Description

Technical Field

[0001] This utility model relates to the field of grass checkerboard laying technology, and in particular to a sand-prevention grass checkerboard laying machine. Background Technology

[0002] Currently, one of the methods used by the state to combat desertification is to set up sand barriers, including straw checkerboard sand barriers and clay sand barriers. Among them, straw checkerboard sand barriers use materials such as wheat straw, rice straw, and reeds to form windbreaks on shifting sand dunes to weaken wind erosion. They also have the effect of intercepting rainfall, which can increase the water content of the sand layer and is conducive to the growth of psammophytic plants.

[0003] Straw checkerboard, as the name suggests, is made by laying bundles of discarded wheat straw in a checkerboard pattern on sand, then shoveling them into the sand, leaving one-third or half of the straw standing upright on the four sides. Then, the sand in the center of the checkerboard is pushed towards the roots of the straw around the edges, making the straw firmly stand on the sand.

[0004] Currently, the laying of straw grids mainly relies on manpower. First, reed stalks or straw mats are laid flat on the ground, and then workers press the middle of the straw mat into the sand by stepping on iron shovels. This laying method has the following problems: 1. Since the pressure on the straw mat is provided by manpower, but the manpower is different, the depth of the straw mat in the sand cannot be consistent, resulting in the straw mat not being firmly fixed.

[0005] 2. During the laying process, the soles of the feet need to apply pressure to the shovel. After working for a period of time, the soles of the feet will feel sore, which will further reduce work efficiency. Moreover, working in the desert is a great test of the physical strength of the workers, and the labor intensity is extremely high.

[0006] Therefore, there is an urgent need for a sand-prevention grass checkerboard laying machine that can replace manual labor in laying grass checkerboards, improve laying efficiency, reduce labor intensity, and ensure the depth of grass checkerboard insertion. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a sand-resistant grass checkerboard laying machine, which solves the problems of inconsistent grass mat depth in the sand, low laying efficiency, and high labor intensity caused by the current reliance on manual labor when laying grass checkerboards.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A sand-prevention grass checkerboard laying machine includes a main body, which includes a connecting frame and a connecting frame. The connecting frame is provided with a rotating seat, and the rotating seat is provided with a drive gear and a linkage gear. The drive gear and the linkage gear are linked by a chain. The drive gear is provided with a drive shaft, and the drive shaft is equipped with a drive source.

[0010] The linkage gear is provided with a crankshaft arm, the upper shaft of which is connected to a rotating arm. The end of the rotating arm away from the crankshaft arm is connected to a transmission frame. At least one column is hinged to one end of the transmission frame, and a shovel plate is hinged to the end of the column away from the transmission frame.

[0011] The column is hinged to a connecting rod upper beam at the end away from the shovel plate, and a connecting rod vertical beam is hinged to one end of the connecting rod upper beam. The middle part of the connecting rod vertical beam is hinged to the transmission frame. Two parallel swing arms are hinged to the connecting rod vertical beam, and the end of the swing arm away from the connecting rod vertical beam is hinged to the connecting frame.

[0012] Furthermore, the transmission frame includes two parallel transmission beams, the connecting rod vertical beam is hinged to the transmission beams, a first crossbeam is provided between the ends of the two transmission beams away from the column, and an extension plate is provided at the other end of the two transmission beams, the extension plate being hinged to the column.

[0013] Furthermore, a pressure sensor is provided between the column and the shovel plate.

[0014] Furthermore, a torque sensor is provided between the drive shaft and the drive source.

[0015] Furthermore, the connecting frame is provided with three connecting ears, which are located on a virtual isosceles triangle, and the connecting ears are used to connect with the traction device.

[0016] Furthermore, it also includes a transfer frame for transferring the main body, the transfer frame including a base frame, the base frame being provided with casters, the base frame being vertically provided with a gantry, and the gantry being provided with a connecting plate connected to the connecting frame.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] (1) The drive source provides driving force to the drive gear through the drive shaft. The drive gear drives the linkage gear and crankshaft arm to rotate through the chain. The crankshaft arm drives the rotating frame and works together with the swing arm and connecting rod vertical beam to place the straw mat into the sand. It can be seen that the straw grid is laid by mechanical means, which ensures the consistency of the pressure of the shovel plate on the straw mat and ensures the insertion depth. At the same time, mechanical laying replaces manual labor, which improves the laying efficiency and reduces the labor intensity of the workers.

[0019] (2) The use of a transfer frame facilitates the transportation and transfer of the main body, and can make the shovel plate contact the ground during transfer to prevent deformation of the shovel plate. Attached Figure Description

[0026] The present invention will now be described clearly and completely with reference to the embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] See appendix Figure 1-5The image shows a sand-resistant grass checkerboard laying machine, which includes a main body 1 and a transfer frame 2 for transferring the main body 1. The main body 1 includes a connecting frame and a connecting frame. The connecting frame is located on one side of the connecting frame. A rotating seat 3 is provided at one end of the top of the connecting frame. A drive gear 5 is installed on the rotating seat 3. A drive shaft is provided on the drive gear 5 through a keyway and a key block. A drive source 4 is provided at one end of the drive shaft on the connecting frame. A linkage gear 6 is installed above the rotating seat 3 on the drive gear 5. The drive gear 5 and the linkage gear 6 are linked by a chain. A crankshaft arm 8 is mounted on the linkage gear 6. A rotating arm 9 is connected to the end of the crankshaft arm 8 away from the linkage gear 6 through a shaft. A transmission frame 10 is welded to the other end of the rotating arm 9.

[0030] The transmission frame 10 is U-shaped and includes two parallel transmission beams 18. A first crossbeam 19 and a second crossbeam 20 are welded parallel to each other at one end of the two transmission beams 18. The rotating arm 9 is connected to the first crossbeam 19 and the second crossbeam 20 respectively. The other ends of the two transmission beams 18 are respectively provided with extension plates 12. One end of the extension plate 12 is hinged to a column 11, and the extension plate 12 is hinged to the middle of the column 11. A pressure sensor 13 is installed at one end of the two columns 11, and the column 11 is connected to a shovel plate 14 through the pressure sensor 13. The other end of the column 11 is hinged to a connecting rod upper beam 15, and the end of the connecting rod upper beam 15 away from the column 11 is hinged to a connecting rod vertical beam. The middle part of the connecting rod vertical beam 16 is hinged to the transmission beam 18. The middle part and the other end of the connecting rod vertical beam 16 are respectively hinged to a swing arm 17. The two swing arms 17 are parallel to each other, and the other ends of the two swing arms 17 are hinged to the connecting frame through the horizontally arranged rotating shaft 21. In use, the drive source 4 drives the drive gear 5 to rotate. The drive gear 5 drives the linkage gear 6 and the crankshaft arm 8 to rotate in a circle by using a chain. When the crankshaft arm 8 rotates in a circle, it drives the rotating arm 9 and the transmission frame 10 to move up and down in conjunction with the connecting rod upper beam 15, the connecting rod vertical beam 16 and the swing arm 17. The shovel 14 further places the straw curtain in the sand to complete the laying of the straw grid.

[0031] Therefore, the above-mentioned mechanical linkage mechanism can drive the shovel plate 14 to complete the laying of grass squares. On the one hand, it replaces manual labor and realizes mechanical laying. Mechanical laying ensures that the pressure of the shovel plate 14 on the grass mat is the same, which further ensures the insertion depth. At the same time, the mechanical replacement of manual labor improves the laying efficiency and reduces the labor intensity. It can achieve continuous operation under the action of the drive source 4.

[0032] Furthermore, the connecting frame is provided with three connecting ears 22 in the shape of an isosceles triangle. The connecting ears 22 are provided with connecting holes. During the laying process, the main body 1 is connected to the traction equipment, such as a tractor, through the three connecting ears 22, and then the traction equipment drives the main body 1 to move.

[0033] Furthermore, a torque sensor 7 is provided between the drive shaft and the drive source 4. During the laying process, the pressure sensor 13 on the shovel 14 feeds back the pressure currently received by the shovel 14 to the industrial control device. The industrial control device then makes a judgment and changes the output torque through the drive source 4. The torque sensor 7 then feeds back the new torque to the control unit. In this way, the pressure sensor 13, the torque sensor 7, the industrial control device, and the drive source 4 form a control closed loop to achieve the adjustment of the pressure of the shovel 14.

[0034] As a sand-prevention grass grid laying machine, the transfer frame 2 includes a base frame 23, with casters 24 on the base frame 23 and a gantry 25 vertically mounted on the base frame 23. The gantry 25 is equipped with a connecting plate 26 that connects to the connecting ear. When transferring the main body 1, the main body 1 can be connected to the connecting plate 26 on the gantry 25 by a pin through the connecting ear 22, and then move through the casters 24. The transfer frame 2 can provide a dedicated parking position for the main body 1.

[0035] It should be noted that the drive source 4 is a three-phase asynchronous motor, and the output torque of the three-phase asynchronous motor is changed by the industrial control device in conjunction with the frequency converter.

[0036] The beneficial effects of this utility model are as follows: When laying grass squares, the drive source 4 drives the drive gear 5 to rotate. The drive gear 5 uses a chain to drive the linkage gear 6 and the crankshaft arm 8 to rotate circumferentially. When the crankshaft arm 8 rotates circumferentially, it drives the rotating arm 9 and the transmission frame 10 to move up and down in conjunction with the upper beam 15 of the connecting rod, the vertical beam 16 of the connecting rod, and the swing arm 17. The shovel 14 further places the grass mat in the sand to complete the laying of grass squares. The mechanical linkage mechanism drives the shovel 14 to complete the laying of grass squares. On the one hand, it replaces manual labor and realizes mechanical laying. The mechanical laying ensures that the pressure of the shovel 14 on the grass mat is the same, which further ensures the depth of placement. At the same time, the mechanical replacement of manual labor improves the laying efficiency and reduces the labor intensity. It can achieve continuous operation under the action of the drive source 4.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
