In addition, the material cleaning device in the above-described embodiment provided by the present disclosure may further have the following additional technical features:
In the above-described technical solution, the stirring assembly comprises: a rotating member disposed in the cleaning chamber and being capable of rotating in the cleaning chamber under the action of the air streams; and a stirring member disposed in the cleaning chamber, connected to the rotating member and used for rotating in the cleaning chamber under the driving of the rotating member, so as to stir the material and the water in the cleaning chamber.
The stirring assembly comprises a stirring member and a rotating member, the rotating member is capable of converting wind energy into mechanical energy to drive the stirring assembly to rotate in the cleaning chamber, and the stirring member can contact the material and exert a stirring force on the material and the water to rotate and tumble the material and the water, thereby achieving the object of cleaning.
In any of the above-described technical solutions, the material cleaning device further comprises: a bracket disposed in the cleaning chamber, fixedly connected to an inner sidewall of the cleaning chamber, and used for supporting the stirring assembly, the stirring assembly being rotatable relative to the bracket.
By providing a bracket in the cleaning chamber to support the stirring assembly such as the rotating member and the stirring member, on the one hand, it is ensured that the rotating member and the stirring member can rotate stably in the cleaning chamber, and on the other hand, it is possible to ensure, by reasonably arranging the position of the bracket, that the rotating member and the stirring member are in proper positions, thereby ensuring that the stirring assembly can maintain a reasonable rotational speed and effectively stir the material and the water.
In any of the above-described technical solutions, the bracket is provided with a first connecting hole; and the stirring member comprises: a connecting rod partially located in the first connecting hole and rotatable in the first connecting hole, the connecting rod being connected to the rotating member so that the rotating member can rotate relative to the bracket with the connecting rod as a shaft; and a stirring rod connected to the connecting rod, extending in a different direction from the connecting rod, and used for stirring the material and the water in the cleaning chamber.
The stirring member comprises a connecting rod and a stirring rod, and the connecting rod is connected to the rotating member, realizing the connection between the stirring member and the rotating member, and ensuring that the rotating member can drive the stirring member to rotate. Moreover, the connecting rod is partially located in the first connecting hole on the bracket, so the rotating member can rotate relative to the bracket with the connecting rod as the shaft, thus effectively ensuring the rotation stability of the rotating member and avoiding deviation and the like, and also ensuring that the stirring rod can rotate stably in the cleaning chamber to rotate and tumble the material and the water relatively regularly. In this way, the function of automatic cleaning is realized, and excessive noise is avoided.
As for the specific connection relationship between the connecting rod and the rotating member, the connection may be fixed connection, and in this way, the rotating member and the stirring member can rotate synchronously, so that the stirring member can quickly stir the material and the water, thereby improving the cleaning efficiency of the material cleaning device. Of course, the connecting rod may also be movable connected to the rotating member, as long as the rotating member can drive the connecting rod to rotate, i.e., the rotation of the stirring member, and thus the stirring function, can be realized.
In any of the above-described technical solutions, the connecting rod longitudinally passes through the first connecting hole, and upper and lower ends of the connecting rod are connected to the rotating member and the stirring rod, respectively; or, an upper end of the connecting rod protrudes from the first connecting hole, the rotating member and the stirring rod are both connected to an upper portion of the connecting rod, and the stirring rod is located below the rotating member.
The connecting rod longitudinally passes through the first connecting hole, and the upper and lower ends of the connecting rod are connected to the rotating member and the stirring rod, respectively, so that the rotating member and the stirring rod are located on the upper and lower sides of the bracket, respectively, specifically with the rotating member being on the upper side, and the stirring rod on the lower side. In this way, on the one hand, the rotating member is prevented from contacting the material and the water, thereby avoiding the resistance caused by the material and the water to the rotation of the rotating member; and on the other hand, it is ensured that the stirring rod can contact the material and the water, and further effectively stir the water and the material, so as to ensure the cleaning effect of the material cleaning device.
The upper end of the connecting rod protrudes from the first connecting hole, the rotating member and the stirring rod are both connected to the upper portion of the connecting rod, and the stirring rod is located below the rotating member, so that both the rotating member and the stirring rod are located on the upper side of the bracket, which is also the case where the rotating member is on the upper side, and the stirring rod is on the lower side. In this way, it is also possible to prevent the rotating member from contacting the material and the water, thereby avoiding the resistance caused by the material and the water to the rotation of the rotating member; and further, it can also be ensured that the stirring rod can contact the material and the water, and further effectively stir the water and the material, so as to ensure the cleaning effect of the material cleaning device.

The limiting groove cooperates with the first limiting bump, realizing the fixed connection between the connecting rod and the rotating member, which leads to a simple structure and convenient assembly. Specifically, during assembly, the rotating member is supported on the bracket, and the second connecting hole on the rotating member is made to communicate with the first connecting hole on the bracket; then the stirring member is installed from bottom to top, so that the connecting rod of the stirring member is inserted into the first connecting hole and the second connecting hole sequentially from bottom to top; and finally the connecting rod is rotated, so that the first limiting bump on the connecting rod is clamped in the limiting groove, in this case, the limiting groove can limit both the rotation of the connecting rod in the second connecting hole and the downward movement of the connecting rod, that is, the limiting groove not only limits the position of the connecting rod, but also supports the connecting rod, thereby ensuring the reliable connection between the rotating member and the stirring member, ensuring that the rotating member and the stirring member can rotate synchronously, and further improving the use reliability of the device.
In any of the above-described technical solutions, the lower end of the connecting rod protrudes from the first connecting hole, and the lower end of the connecting rod is formed with a second limiting bump having a larger cross-sectional area than the first connecting hole.
The lower end of the connecting rod protrudes from the first connecting hole, i.e., whether the stirring rod is connected to the upper portion or the lower portion of the connecting rod, the connecting rod always longitudinally passes through the first connecting hole, which maximizes the depth of insertion of the connecting rod into the first connecting hole, thereby effectively avoiding inclination of the connecting rod, etc., and further improving the stability of the stirring member and the rotating member when rotating. The arrangement of the second limiting bump can limit the upward movement of the connecting rod, which further ensures the relative stability between the connecting rod and the bracket, thereby further ensuring the stable supporting of the stirring assembly by the bracket, and further ensuring the relative stability between the stirring member and the rotating member and ensuring that the stirring member and the rotating member can rotate stably. In addition, for the technical solution in which the stirring rod is connected to the lower end of the connecting rod, the stirring rod can be directly connected to the limiting bump, which is simple in structure and is an ingenious design.
In any of the above-described technical solutions, the stirring rod extends in a direction close to the bottom of the inner sidewall of the cleaning chamber.

In any of the above-described technical solutions, there are a plurality of stirring rods, and the plurality of stirring rods each form a different angle with the connecting rod.
As there are a plurality of stirring rods and the plurality of stirring rods each form a different angle with the connecting rod, the plurality of stirring rods each have a different stirring radius, which further increases the material and the water the stirring rod can stir, and enables the material and the water to tumble while rotating, thereby further improving the cleaning effect of the material cleaning device.
In any of the above-described technical solutions, the bracket comprises: a support column, by which the stirring assembly is supported and in which the first connecting hole is provided; and a support rib having one end connected to the support column and the other end fixedly connected to the inner sidewall of the cleaning chamber.
The bracket comprises a support column and a support rib. The support column is capable of supporting the stirring assembly such as the rotating member and the stirring member, thereby realizing the supporting function of the bracket; the first connecting hole is provided in the support column, and the connecting rod is partially located in the first connecting hole, ensuring that the rotating member can rotate relative to the bracket with the connecting rod as the shaft, thereby ensuring the reliable connection between the stirring assembly and the bracket; and one end of the support rib is connected to the support column and the other end thereof is fixedly connected to the inner sidewall of the cleaning chamber, realizing the fixed connection between the bracket and the cleaning chamber.
In any of the above-described technical solutions, the support column, the support rib and the cleaning chamber are a one-piece structure; and/or there are a plurality of support ribs, and the plurality of support ribs are uniformly distributed in a circumferential direction of the support column.
The support column, the support rib and the cleaning chamber are a one-piece structure, which, on the one hand, improves the connection strength between the support column and the support rib and the connection strength between the support rib and the cleaning chamber, and reduces the probability that the bracket will fall off or break, thereby further improving the use reliability of the material cleaning device; and on the other hand, improves the production efficiency of the product and reduces the production cost of the product, as the support column, the support rib and the cleaning chamber can be integrally formed.
There are a plurality of support ribs, and the plurality of support ribs are uniformly distributed in a circumferential direction of the support column, which further improves the strength and supporting stability of the bracket.

In any of the above-described technical solutions, the bottom of the cleaning chamber is provided with a material outlet; and the material cleaning device further comprises a valve connected to the cleaning chamber and movable relative to the cleaning chamber to close or open the material outlet.
The arrangement of the material outlet and the valve facilitates the automatic discharge after the completion of material cleaning, thereby further improving the automation degree of the material cleaning device and further increasing the market competitiveness of the product. Specifically, in the cleaning process, the valve is kept closed, and the material and the water rotate and tumble in the cleaning chamber to realize automatic cleaning; and after the completion of the cleaning, the valve moves relative to the cleaning chamber to open the material outlet, and the material is discharged through the material outlet under the action of gravity to realize automatic discharge.
In any of the above-described technical solutions, the bottom of the cleaning chamber is completely opened to form the material outlet.

In any of the above-described technical solutions, a sealing member for sealing the material outlet is further provided between the valve and the cleaning chamber.
The arrangement of the sealing member effectively ensures the sealing connection between the valve and the cleaning chamber, thereby preventing the air streams or water from leaking to the outside through the joint between the valve and the cleaning chamber, and further improving the use reliability of the device.
In any of the above-described technical solutions, the sealing member is a sealing ring.
The sealing member is a sealing ring, and the sealing ring is reliable in sealing and low in price.
In any of the above-described technical solutions, the top of the cleaning chamber is completely open; and the material cleaning device further comprises a cleaning cover being capable of covering the cleaning chamber so as to close the cleaning chamber.
The top of the cleaning chamber is completely open, facilitating the assembly, repair and replacement of the stirring assembly.
In any of the above-described technical solutions, the air inlet coincides with the material inlet or the water inlet.
The air inlet coincides with the material inlet or the water inlet, that is, the air inlet shares a single inlet with the material inlet, or the air inlet shares a single inlet with the water inlet, which simplifies the structure of the cleaning chamber and is beneficial to product cost saving.
It should be explained that, since the material cleaning device of the present disclosure mainly utilizes air streams to drive the stirring assembly to rotate so as to realize the stirring of the material and the water, there is no strict requirement on the order of the transport of the material and the water into the cleaning chamber, and it is only required that after the material and the water are transported into the cleaning chamber, air streams can enter the cleaning chamber and drive the stirring assembly to rotate; and as to whether the air streams are transported therein through a special air inlet, through the material inlet (i.e. the air inlet shares a single inlet with the material inlet), or through the water inlet (i.e. the air inlet shares a single inlet with the water inlet), it makes no difference, and they can all achieve the object of the present disclosure.
It should be noted that, for the technical solution in which the air inlet shares a single inlet with the material inlet, pneumatic feeding can also be realized, i.e., the material is fed into the cleaning chamber by means of the air streams, which has high feeding efficiency, and is clean and pollution-free. For the order of transport of the air streams and the material, it is feasible to first transport the material through the material inlet, and then transport the air streams through the material inlet for cleaning; and it is also feasible to transport the material and the air streams simultaneously, i.e., the material is transported into the cleaning chamber under the action of the air streams, and then the water and the material rotate and tumble under the action of the air streams to realize automatic cleaning. The latter is preferable, and in this way, in the process of transporting the material into the cleaning chamber under the action of the air streams, tumbling and rubbing will also occur to the material under the action of the air streams, so that particles such as starch adhered to the surface of the material will partially fall off, i.e., the air stream feeding has certain dry cleaning effect on the material, thereby further improving the material cleaning effect of the material cleaning device.
In any of the above-described technical solutions, the cleaning chamber is further provided with an air outlet and a water outlet.
The arrangement of the air outlet can prevent the air pressure in the cleaning chamber from being too high, so that high-pressure air streams can be continuously introduced into the cleaning chamber, thereby ensuring the cleaning effect of the device. The arrangement of the water outlet makes it convenient to automatically discharge the water after the completion of the cleaning, and the water outlet is kept in the closed state during the cleaning process, which not only can prevent loss of the air streams, but also can avoid the use of a large amount of water.
In any of the above-described technical solutions, the air outlet is porous; and/or the water outlet is porous; and/or the air inlet, the water inlet, the air outlet and the water outlet are all provided on the sidewall of the cleaning chamber; and/or the material inlet is located at the upper portion of the cleaning chamber.
The air outlet is porous, and the pore diameter of the air outlet is smaller than the particle diameter of the material in the cleaning chamber, which not only ensures normal air exhaust of the cleaning chamber, but also prevents the material from being discharged from the air outlet, thus further improving the use reliability of the device. The water outlet is porous, and the pore diameter of the water outlet is smaller than the particle diameter of the material in the cleaning chamber, which not only ensures normal water drainage of the cleaning chamber, but also prevents the material from being discharged from the water outlet. The air inlet, the water inlet, the air outlet and the water outlet are all provided on the sidewall of the cleaning chamber, which is simple in structure, facilitates the overhaul of the device and also does not affect automatic material discharge of the device. The material inlet is located at the upper portion of the cleaning chamber, which can prevent the water in the cleaning chamber from pouring into the material inlet. In the specific use process, at the time of cleaning the material, the air outlet is opened and the water outlet is closed so as to reduce the loss of air streams, and use of a large amount of water can also be avoided; and when cleaning has been completed, the air outlet is closed and the water outlet is opened, so that the water can be discharged under the action of gravity and the air streams.

Moreover, the connecting rod 221 is partially located in the first connecting hole 311 on the bracket 30, so the rotating member 21 can rotate relative to the bracket 30 with the connecting rod 221 as the shaft, thus effectively ensuring the rotation stability of the rotating member 21 and avoiding deviation and the like, and also ensuring that the stirring rod 222 can rotate stably in the cleaning chamber 10 to rotate and tumble the material and the water relatively regularly.

The connecting rod 221 longitudinally passes through the first connecting hole 311, and the upper and lower ends of the connecting rod 221 are connected to the rotating member 21 and the stirring rod, respectively, so that the rotating member 21 and the stirring rod 222 are located on the upper and lower sides of the bracket 30, respectively, specifically with the rotating member 21 being on the upper side, and the stirring rod 222 on the lower side. In this way, on the one hand, the rotating member 21 is prevented from contacting the material and the water, thereby avoiding the resistance caused by the material and the water to the rotation of the rotating member 21; and on the other hand, it is ensured that the stirring rod 222 can contact the material and the water, and further effectively stir the water and the material, so as to ensure the cleaning effect of the material cleaning device 1.
Alternatively, the upper end of the connecting rod 221 protrudes from the first connecting hole 311, the rotating member 21 and the stirring rod 222 are both connected to the upper portion of the connecting rod 221, and the stirring rod 222 is located below the rotating member 21, so that both the rotating member 21 and the stirring rod 222 are located on the upper side of the bracket 30, which is also the case where the rotating member 21 is on the upper side, and the stirring rod 222 is on the lower side.

In the above-described embodiments, the arrangement of the material outlet and the valve 40 facilitates the automatic discharge after the completion of material cleaning, thereby further improving the automation degree of the material cleaning device 1 and further increasing the market competitiveness of the product. Specifically, in the cleaning process, the valve 40 is kept closed, and the material and the water rotate and tumble in the cleaning chamber 10 to realize automatic cleaning; and after the completion of the cleaning, the valve 40 moves relative to the cleaning chamber 10 to open the material outlet, and the material is discharged through the material outlet under the action of gravity to realize automatic discharge.
The bottom of the cleaning chamber 10 is completely opened to form the material outlet, which maximizes the size of the material outlet, thereby significantly increasing the material discharge speed of the material cleaning device 1.
The arrangement of the sealing member effectively ensures the sealing connection between the valve 40 and the cleaning chamber 10, thereby preventing the air streams or water from leaking to the outside through the joint between the valve 40 and the cleaning chamber 10, and further improving the use reliability of the device.
The sealing member is a sealing ring 50, and the sealing ring 50 is reliable in sealing and low in price.
The top of the cleaning chamber 10 is completely open, facilitating the assembly, repair and replacement of the stirring assembly 20.

In the above-described embodiments, the air inlet coincides with the material inlet 11 or the water inlet 12, that is, the air inlet shares a single inlet with the material inlet 11, or the air inlet shares a single inlet with the water inlet 12, which simplifies the structure of the cleaning chamber 10 and is beneficial to product cost saving.
It should be explained that, since the material cleaning device 1 of the present disclosure mainly utilizes air streams to drive the stirring assembly 20 to rotate so as to realize the stirring of the material and the water, there is no strict requirement on the order of the transport of the material and the water into the cleaning chamber 10, and it is only required that after the material and the water are transported into the cleaning chamber 10, air streams can enter the cleaning chamber 10 and drive the stirring assembly 20 to rotate; and as to whether the air streams are transported therein through a special air inlet, through the material inlet 11 (i.e. the air inlet shares a single inlet with the material inlet 11), or through the water inlet 12 (i.e. the air inlet shares a single inlet with the water inlet 12), it makes no difference, and they can all achieve the object of the present disclosure.
It should be noted that, for the embodiment in which the air inlet shares a single inlet with the material inlet 11, pneumatic feeding can also be realized, i.e., the material is fed into the cleaning chamber 10 by means of the air streams, which has high feeding efficiency, and is clean and pollution-free. For the order of transport of the air streams and the material, it is feasible to first transport the material through the material inlet 11, and then transport the air streams through the material inlet 11 for cleaning; and it is also feasible to transport the material and the air streams simultaneously, i.e., the material is transported into the cleaning chamber 10 under the action of the air streams, and then the water and the material rotate and tumble under the action of the air streams to realize automatic cleaning. The latter is preferable, and in this way, in the process of transporting the material into the cleaning chamber 10 under the action of the air streams, tumbling and rubbing will also occur to the material under the action of the air streams, so that particles such as starch adhered to the surface of the material will partially fall off, i.e., the air stream feeding has certain dry cleaning effect on the material, thereby further improving the material cleaning effect of the material cleaning device 1.

In the above-described embodiments, the arrangement of the air outlet 13 can prevent the air pressure in the cleaning chamber 10 from being too high, so that high-pressure air streams can be continuously introduced into the cleaning chamber 10, thereby ensuring the cleaning effect of the device. The arrangement of the water outlet 14 makes it convenient to automatically discharge the water after the completion of the cleaning, and the water outlet 14 is kept in the closed state during the cleaning process, which not only can prevent loss of the air streams, but also can avoid the use of a large amount of water.
The air outlet 13 is porous, and the pore diameter of the air outlet 13 is smaller than the particle diameter of the material in the cleaning chamber 10, which not only ensures normal air exhaust of the cleaning chamber 10, but also prevents the material from being discharged from the air outlet 13, thus further improving the use reliability of the device. The water outlet 14 is porous, and the pore diameter of the water outlet 14 is smaller than the particle diameter of the material in the cleaning chamber 10, which not only ensures normal water drainage of the cleaning chamber 10, but also prevents the material from being discharged from the water outlet 14. The air inlet, the water inlet 12, the air outlet 13 and the water outlet 14 are all provided on the sidewall of the cleaning chamber 10, which is simple in structure, facilitates the overhaul of the device and also does not affect automatic material discharge of the device. The material inlet 11 is located at the upper portion of the cleaning chamber 10, which can prevent the water in the cleaning chamber 10 from pouring into the material inlet 11. In the specific use process, at the time of cleaning the material, the air outlet 13 is opened and the water outlet 14 is closed so as to reduce the loss of air streams, and use of a large amount of water can also be avoided; and when cleaning has been completed, the air outlet 13 is closed and the water outlet 14 is opened, so that the water can be discharged under the action of gravity and the air streams.
