The present invention relates to the field of garden tools, in particular to a device for aerating the lawn.
In the stadium, football field and other sports venues, as well as in the square green space, parks and other leisure sites, a large number of lawns are often laid, even in some family courtyards, lawns are often planted to beautify the environment. However, as the lawn planting time goes by, the soil on the lawn will gradually harden, and the grass growing on the hard soil will not be able to take root easily. And when the soil hardens, even if the grass has taken root, the oxygen and water supply to the root is insufficient, preventing the grass from growing properly. This will cause the lawn not only to expose the bare land and fail to achieve the effect of beautifying the environment, but also more likely to have poor drainage and ponding. This problem can be solved by aerating the lawn.
At present, some large lawns (football fields, greens, etc.) usually use large aerating devices to aerate the lawn, but these devices need to be purchased at a high cost, and their economic cost is high. Moreover, for some small lawns (courtyards, gardens, etc.), the use of large aerating devices is not realistic. Therefore, in order to solve the technical problem of aerating lawns, it is necessary to develop an aerating device with low cost and high convenience suitable for small lawns.
The object of the present invention is to solve the problems existing in the prior art and provide an assembled device aerating the lawn by perforating, the device can realize the loosening of the soil and aeration of the soil by perforating the lawn.
The specific technical scheme of the present invention is as follows:
a holding part for the user to hold;
a connecting part, one end is detachably connected and fixed with the holding part, the other end is detachably connected and fixed with a ground inserting part;
a ground inserting part is used for perforating the lawn under the action of down pressure, the ground inserting part is provided with at least one plug, and the plug is a hard hollow pipe, and the bottom of the hard hollow pipe is an oblique incision with a tip, and the top of the plug is provided with a soil outlet, the inner diameter of the hard hollow pipe gradually increases from the oblique incision to the soil outlet.
It should be noted that the orientation of “bottom” and “top” mentioned here is illustrated by the use of the whole device in
Preferably, the holding part is a T-shaped tube composed of a series of horizontal tubes and a series of vertical tubes,
Preferably, the connecting part is a series of straight tubes.
Preferably, detachable connection and fixing forms comprise snap connection, muff coupling, thread connection or connection through detachable connectors.
Preferably, the connecting part comprises two hard steel pipes side by side, and both ends of each hard steel pipe are processed into concave forms, and the two concave surfaces at the same end of the connecting part are opposite to each other, forming a connection structure holding the holding part or the connecting part.
Preferably, the concave surface is provided with connecting holes for screwing into the connectors.
Preferably, the ground inserting part is provided with a trodden part for applying down pressure to the plug.
Preferably, the trodden part is a pedal made of angle steel.
Preferably, the holding part, connecting part and ground inserting part are made of steel.
Preferably, the ground inserting part is provided with two or more plugs.
The device of the present invention is to aerate the soil by perforating the lawn, after perforating, the air can directly enter the depth of the soil and improve the internal environment, at the same time, the holes can also improve the loose degree of the surrounding lawn soil, so as to facilitate drainage and solve various problems caused by the hardening of the lawn soil. The present invention can be disassembled as a whole and used by the user's own assembly, which reduces the volume and is more suitable for aerating the small lawn.
holding part a, connecting part b, ground inserting part c, handle 1, arc surface 2, pedal 3, plug 4, oblique incision 5, soil outlet 6.
The present invention is further described below in combination with the drawings and specific embodiments. The technical features of each embodiment in the present invention can be combined accordingly on the premise of no conflict.
As shown in
The function of the holding part a is for the user to hold, in this embodiment, its structure adopts T-shaped tube as shown in
Of course, the specific form of the holding part a can be adjusted according to the actual situation, it is not limited to this.
The function of the connecting part b is to detachably connect the holding part a and the ground inserting part c. In this embodiment, the connecting part b is a series of straight tubes, which is composed of two steel pipes as shown in
Of course, the structural form of the connecting part b can also be varied, in addition to the form composed of the above two steel pipes, the connecting part b can also adopt the connection way of the large pipe embracing the small pipe, a thick pipe is connected to the end of the holding part a and the ground inserting part c, and the connection is fixed by interference fit, snap connection, thread connection, etc.
The ground inserting part is used for perforating the lawn under the action of down pressure. The perforating in the present invention is realized through plug 4, so at least one plug 4 is arranged on the ground inserting part c. As shown in
Furthermore, some lawn soil may be too hard to be inserted. The user's pressure on the holding part a alone may not be enough to insert the plug 4 into the soil. Therefore, a trodden part can be installed on the ground inserting part c to apply pressure on the plug 4. In this embodiment, the trodden part is a pedal 3 fixed on the plug connection frame, and the pedal 3 can be made of angle steel and other materials to ensure its strength. Of course, the trodden part is not necessarily a single fixed component, but can also be a convenient position for trampling on the ground inserting part c itself, for example, the plug connection frame in
In addition, generally considering the efficiency, two or more than two plugs 4 can be equipped in order to form a multiple holes to improve the work efficiency. However, too many plugs 4 will also cause the volume of the whole device to be too large, or the pressure required by a single perforating is too large, so the number of plug 4 set on the ground inserting part c can be increased or deleted according to needs. At the same time, the hollow plug 4 can be replaced by solid pointed spikes according to the actual demand, and two or more pointed spikes can also be provided.
Finally, in this embodiment, the holding part a, the connecting part b and the ground inserting part c are all made of steel, but other metal materials, plastics or other high-strength polymer materials can also be used, as long as they can meet the strength requirements for perforating.
The device aerates the soil by perforating the lawn, after perforating, the air can directly enter the depth of the soil and improve the internal environment, at the same time, the holes can also improve the loose degree of the surrounding lawn soil, so as to facilitate drainage and solve various problems caused by the hardening of the lawn soil.
The above embodiments are only a better scheme of the present invention, but they are not intended to limit the present invention. those having ordinary skills in the art may also make various changes and variations under the condition that they do not deviate from the spirit and scope of the present invention. Therefore, all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
