[0002] Grassland rodent damage refers to the phenomenon that rodents (such as plateau pikas, zokors, etc.) in the grassland ecosystem cause destructive impacts on vegetation, soil, and animal husbandry due to overpopulation. The main hazards include vegetation damage, soil structure damage, ecological and economic chain reactions, etc. Existing grassland rodent damage control mainly achieves through trapping, biological control, and fencing.

By forming a trench inserting mechanism with a mounting plate and an inserting knife, and cooperating with a counterweight, a first slider inside the first chute, and a driving mechanism, it can not only continuously insert and pull out on the grassland once to form a thin trench for installing a fine iron wire mesh, avoiding throwing forage and soil into the air, resulting in a poor operating environment, but also the counterweight can increase the initial velocity of the inserting knife moving downward, splitting and crushing hard objects such as stones, avoiding damage to the inserting knife, and improving the efficiency of trench digging and net burying, facilitating the isolation and control of rodent damage.

[0004] The invention with the publication number CN110005005B discloses a rodent damage control isolation trench digging and net burying device, including a traction device, a fixed frame, a height-adjusting hydraulic device, a width-adjusting hydraulic device, a transmission mechanism, and a slicing assembly; the fixed frame is installed on the traction device, one side of which is a movable bracket, and the opposite side is a fixed bracket; height-adjusting hydraulic devices are symmetrically and respectively installed on the movable bracket and the fixed bracket; a width-adjusting hydraulic device is connected between the movable bracket and the fixed bracket; the transmission mechanism includes a transmission bearing seat, a power transmission shaft, a gear fixing box, a first bevel gear, a second bevel gear, and a slicing transmission shaft; the slicing assembly includes a fixed slicing and a movable slicing.

[0005] However, the above metal mesh installation devices for rodent damage control still have the following problems in actual use: during the process of burying the net, the depth of the metal mesh installation device is not easy to adjust. Due to the differences in the soil of different grasslands, the method of burying the net at a unified height cannot ensure the stability of the metal mesh. After digging the trench and burying the net, the backfilling force is insufficient, and manual assistance is often required for compaction and leveling. At the same time, the existing net burying devices usually can only bury single-piece metal meshes, and operators need to continuously replenish the metal meshes, which reduces the net burying efficiency and affects the net burying progress during operation.

[0022] Preferably, the backfilling mechanism includes a contact cone plate, and the contact cone plate is fixedly installed at the upper end of the rotating shaft of the backfilling turntable. After the contact cone plate rotates with the backfilling turntable, it contacts the bottom surface of the pressing plate, and the pressing plate realizes reciprocating lifting in the up and down direction by intermittently contacting the contact cone plate, so as to press the soil in the backfilled ditch, thereby improving the stability of the buried metal mesh.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: For this metal mesh burying device for preventing and controlling rodent pests in grasslands, the adjustable-height ditch-opening plow head reduces obstruction during the ditch-opening process by reciprocating up and down, so that the released metal mesh is buried by the mesh-entering support after being sprayed with the medicament. At the same time, the oppositely distributed backfilling turntables cooperate with the reciprocatingly lifting pressing plate to press the backfilled soil, improving the stability of the buried metal mesh. The specific content is as follows:

[0024] 1. When the traveling guide wheels drive the mesh-burying frame to move during mesh burying, the servo motor drives the linked lifting threaded rod to rotate. Under the action of the thread, the mesh-burying frame drives the lifting platform to adjust the height. The ditch-opening mechanism, mesh-entering mechanism, and backfilling mechanism above the lifting platform are driven to lift, thereby changing the mesh-burying depth to adapt to the mesh-burying requirements under different grassland soils.

[0025] 2. The ditch-opening plow head is inserted into the grassland. The driving rotating shaft connected by the first belt pulley assembly rotates the traveling guide wheels through the engagement of the first bevel gear set. The driving rotating shaft drives the transmission rotating shaft to rotate through the second bevel gear set. The bottom end of the contact cam intermittently contacts and fits the ditch-opening plow head, causing the ditch-opening plow head to lift up and down inside the grassland, thereby avoiding the influence of the hardened soil in the grassland on the progress of the ditch-opening operation.

[0026] The lifting platform drives the transmission rotating shaft to lift the second bevel gear set connected to the cage. Then, the second bevel gear set slides on the outer wall of the driving rotating shaft, so that the ditch-opening plow head can be driven by the rotation of the traveling guide wheels to cooperate with the positioning plow base elastically connected above for ditch-opening operations at different buried mesh heights.

[0027] 3. The metal mesh roll is inserted into the internal storage mesh ring frame, and the end of the metal mesh is pulled into the mesh-entering support. At the same time, the end of the metal mesh enters the ditch opened by the ditch-opening mechanism through the mesh-entering chute. At the same time, during the movement of the mesh-burying frame, the mesh-entering guide wheel set driven by the motor inside the mesh-entering support rotates, so as to drive the attached metal mesh downward by the mesh-entering guide wheel set.

[0028] The transmission rotating shaft drives the conveying rotating shaft connected by the second belt pulley assembly to rotate through the third bevel gear set. The conveying rotating shaft drives the guiding pipe inside the worm conveying disc to conduct negative pressure conveying of the liquid medicine, so that the liquid medicine inside the pest control medicine tank is conveyed and sprayed by the worm conveying disc spraying assembly, so that the spraying assembly sprays the liquid medicine onto the surface of the unrolled metal mesh, and the double prevention and control of rodent pests are realized through the burial of the metal mesh and the liquid medicine.

[0029] 4. The driving motor drives the meshing backfill turntable to rotate in the opposite direction through the fourth bevel gear group, so as to push the soil of the previously excavated ditch into the ditch, so that the ditch can be backfilled with soil and the metal mesh below can be buried in the ditch.

[0030] The backfill turntable drives the resistance cone to rotate continuously. The cone head of the resistance cone moves to the bottom surface of the pressing bottom plate and is driven to rise upward. After the cone head of the resistance cone rotates out of place, it is driven to quickly press the grass after backfilling through the contraction of the elastic telescopic slide rod, thereby achieving reciprocating pressing and compacting of the backfilled soil to prevent rodents from digging and affecting the stability of the buried metal mesh.

A metal mesh embedding equipment for grassland rodent control includes a mesh embedding frame 1 and traveling guide wheels 2 rotatably arranged at the four corners of the bottom end of the mesh embedding frame 1. A lifting platform 3 is slidably arranged inside the mesh embedding frame 1. Lifting screw rods 10 are rotatably arranged at the four corners of the top end of the lifting platform 3 through bearings. The upper ends of the lifting screw rods 10 thread through the inside of the mesh embedding frame 1. The symmetrically arranged lifting screw rods 10 are interconnected through a sprocket assembly. A servo motor 11 is fixedly arranged at the top end of the lifting screw rod 10. The servo motor 11 drives the rotation of the lifting screw rod 10 to drive the lifting platform 3 to adjust the mesh embedding height.

[0045] As Figure 1 , Figure 3 shown, the mesh embedding frame 1 moves through the traveling guide wheels 2 arranged at the four corners of the bottom surface for mesh embedding operations. At the same time, the servo motor 11 installed above the mesh embedding frame 1 drives the interconnected lifting screw rods 10 to rotate. Thus, under the action of the thread between the lifting screw rods 10 and the mesh embedding frame 1, the lifting platform 3 arranged at the bottom end is driven to adjust the height. The canal-opening mechanism, mesh-entering mechanism, and backfilling mechanism arranged above the lifting platform 3 are driven to lift, thereby changing the mesh embedding depth to adapt to the mesh embedding requirements under different grassland soils.

[0048] As Figures 4-6 shown, the descending lifting platform 3 drives the open-channel plow head 5 arranged at the front end to insert into the grassland. Then, the movement of the burying net frame 1 causes the traveling guide wheel 2 to rotate. The driving rotating shaft 12 connected through the first belt pulley assembly 14 rotates through the first bevel gear set 13 meshing with the traveling guide wheel 2. Then, the rotating driving rotating shaft 12 drives the transmission rotating shaft 15 to rotate through the second bevel gear set 16 connected by sleeved sliding.

The bottom end of the contact cam 18 intermittently contacts and fits the open-channel plow head 5, so that the open-channel plow head 5 moves up and down inside the grassland, thereby avoiding the hardened soil in the grassland affecting the progress of the open-channel operation.

[0049] Furthermore, when the lifting platform 3 adjusts its height up and down, it drives the transmission rotating shaft 15 at the left end to drive the second bevel gear set 16 connected by the cage 17 to lift. Then, the second bevel gear set 16 slides on the outer wall of the driving rotating shaft 12, so that the open-channel plow head 5 can be driven by the rotation of the traveling guide wheel 2 to cooperate with the positioning plow base 4 elastically connected above for open-channel operation under burying net operations at different heights.
