1. Field of the Invention
This invention relates to a wooden debris compressor, particularly to one compressing wooden debris into wooden debris blocks for use.
2. Description of the Prior Art
Common wooden machines produce lots of wooden debris in their operation, and light and fluffy wooden debris may easily fly around in the air, giving bad effect to the air quality and human health. In disposing it in a bag or container, it needs much space, and moreover, it is also very flammable, having potential danger of get burned to cause disaster to lives and real estates.
A conventional wooden debris compressor has been developed, storing wooden debris in a storing tank with a poking device provided therein, for poking wooden debris to fall into a compressing device. Then a pressing rod in the compressing device compresses wooden debris into debris blocks.
However, common wooden debris is not in power condition to cause bridged conditions in case it is deposited and accumulated in a vertical condition so wooden debris may not easily fall into the feeding device in the conventional wooden debris compressor just described above. Therefore a poking device is used in the conventional compressor for an attempt of breaking bridging conditions. But the poking device has an elongate poking rod with only a little dimension for poking, incapable to break bridging condition completely and leaving some unbroken portion of the bridging conditions of wooden debris. Therefore, wooden debris cannot smoothly be fed into the feeding device, interrupting the operation of the conventional wooden debris compressor. In addition, during the process of wooden debris falling from the bottom of the storing tank to the feeding rod, bridging conditions may also happen so enough wooden debris may not move into the compressing device, causing interruption of compressing operation. Besides, the compressing device may also operate even in case of no load, resulting in waste of time and troubles in operational process.
This invention has been devised to offer a wooden debris compressor, which is provided with a plural poking rods in a poking device under a storing tank, for controlling falling volume of wooden debris by back-and-forth rotation of the poking rods, and also for breaking bridging conditions of wooden debris by ax-shaped knives at the end of the poking rods so as to let wooden debris smoothly fall down through the feeding hole. Further, a cutting device with a cutter is provided on a material room of the feeding device so the bridging conditions of wooden debris formed in the upper portion of the material room can be also broken by the cutter to fall easily down to the bottom. Thus, the wooden debris compressor in the invention breaks in due time bridging conditions possible formed under the storing tank and on the feeding device to continuously and smoothly compress wooden debris, effectively getting rid of the drawbacks of the conventional wooden debris compressor, that is, interruption of compressing operation and idle running of the power under no load.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a wooden debris compressor in the present invention, as shown in
The compressing device 20 consists of a base member 21, a compress room 211 formed on the base member 21, a liquid cylinder 22 with a compress rod 23 that extends and reciprocates in the compress room 211 for compressing wooden debris into blocks, and a pressure tube 24 fixed at the other end of he liquid tank 22 and communicating with the compress room 211. The pressure tube 24 has two opposite lengthwise slots 241 to divide it into two half tubes 242 that can expand to some extent in case of pressure caused by wooden debris compressed therein. Further, a debris block outgoing tube 25 is fixed with an outer end of the pressure tube 24, for finished debris blocks to stay therein temporarily and be gradually pushed out.
The feeding device 30 shown in
The storing tank 40 is fixed on the feeding device 30, having a storing hollow 41 to store wooden debris therein, a fall hole 42 formed in the bottom of the storing tank 41 and communicating with the dropping hole 312 of the feeding device 30 for wooden debris to fall from the fall hole 42 into the material room 311.
The poking device 50 is located under the storing tank 41, consisting of a rotary shaft 51 and three poking rods 52 all connected with and rotated simultaneously by the rotary shaft 51, an ax-shaped knife 53 respectively formed at the ends of two of the three poking rods 52 and able to move back and forth on the hole 42 during back-and-forth rotation of the poking rods 52.
The reciprocating device 60 is fixed under the poking device 50, consisting of a pull rod 61 fixed at the outer side of the feeding rod 33 of the feeding device 30 and moving together with the feeding rod 33, and a first connect rod 62 pivotally connected to the other end of the pull rod 61, a second connect rod 63 pivotally connected with the other end of the first connect rod 62 and having its other end fixed firmly with the rotary shaft 51 so the rotary shaft 51 may be rotated back and forth, with the poking rods 52 rotated back and for the forth alternately.
The cutting device 70 is located on the material room 311 of the feeding device 30, consisting of a liquid cylinder 71 with a piston rod having its outer end fixed with a cross-shaped cutter 72 so that the cutter 72 may move back and forth in the upper portion of the material room 311.
The cooling device 80 is fixed on the base 10, consisting of a blower 81, and a wind pipe 82 connected to the blower 81 for sending cool air sucked into the pressure tube 24 to cool down the pressure tube 24 to prevent it from inflating by heat.
The clamping device 90 is fixed on the base 10, consisting of a stationary clamping block 91, a movable clamp block 92 and a liquid cylinder 93. The stationary clamp block 91 is fixed on an outer surface of one of the two half tubes 242 of the pressure tube 24, and the movable block 92 is connected to and moved back and forth by the piston rod of the liquid cylinder 93, fixed on the other of the two half tubes 242 so that the pressure tube 24 may be clamped by the two blocks 91 and 92 together to restrict the expansion of the pressure tube 24. Further, the liquid cylinder 93 can be adjusted in its liquid pressure for adjusting the density of wooden debris blocks to be compressed.
In operating the wooden debris compressor, referring to
Next, it is necessary to mention that as shown in
The invention has the following advantages, as can be understood from the foresaid description.
1. Provision of the ax-shape knives fixed at the outer ends of he poking rods 52 and the cutting device 70 on the material room 311 of the feeding device 30 can break bridging conditions of wooden debris in due time, ensure smooth dropping of wooden debris through the fall hole 42 of the storing tank 41 and then in the lower portion of the material room 31, carrying out compressing operating without interruption or idle operation.
2. As the ax-shape knives 53 of the poking rods 52 have the same size as the fall holes 42, the volume of wooden debris dropping therethrough are almost the same every time so as to let the volume of the wooden debris falling down controllable.
3. As the pressure tube 24 is clamped elastically by the clamping device 90, the pressure tube 24 can be restricted in its expansion by adjusting the liquid pressure in the liquid cylinder 9, for controlling the density of the finished debris blocks (a), and besides, the liquid pressure can be adjusted according to the condition of wooden debris, such as its powder or particle or thin sheet shape, density, coarseness, etc., for making debris blocks (a) of a preset density.
4. The density of debris blocks can be effectively controlled, as the pressure tube 24 can be prevented from inflating caused by heat, as the cooling device 80 is matched with the compressing device 20 for cooling the pressure tube 24.
5. The pull rod 61 of the reciprocating device 60 is moved by the liquid cylinder 32, so the reciprocating device 60, the poking device 50 and the feeding device 30 are all operated by the same liquid pressure system, saving the cost of the machine and ensuring accurate operational sequence of those devices.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
