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

[0003] The invention with the publication number CN115573414B discloses a rodent control isolation trench digging and net burying device. By forming a trench inserting mechanism with a mounting plate and an inserting knife, and cooperating with a counterweight block, 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 block 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 control isolation trench digging and net burying device, including a traction device, a fixed frame, a height adjustment hydraulic cylinder, a width adjustment hydraulic cylinder, a transmission mechanism, and a slicing assembly; the fixed frame is installed on the traction device, with a movable bracket on one side and a fixed bracket on the opposite side; height adjustment hydraulic cylinders are symmetrically and respectively installed on the movable bracket and the fixed bracket; a width adjustment hydraulic cylinder 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 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.

[0006] Therefore, we propose a metal mesh burying device for grassland rodent control to solve the problems raised above. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the metal mesh burying device for preventing and controlling rodent pests in grasslands can reduce obstruction by reciprocating lifting of the channel opening plow head with adjustable height during the channel opening process, so that the released metal mesh can be buried by the net entry bracket after being sprayed with the agent, and at the same time, the backfilling turntables distributed in opposite directions cooperate with the reciprocating lifting pressing bottom plate to press the backfilled soil, thereby improving the stability of the metal mesh burying. The specific contents are as follows: 1. The travel guide wheel drives the buried net frame to move during the buried net operation. The servo motor drives the linked lifting threaded rod to rotate, and the buried net frame drives the lifting platform to adjust the height under the action of the thread. The channel opening mechanism, net entry mechanism and backfilling mechanism above the lifting platform are driven to rise and fall, thereby changing the buried net depth to adapt to the buried net requirements under different grassland soils.

[0019] 2. The canal plowshare is inserted into the grass, and the driving shaft connected to the first pulley assembly rotates by engaging the travel guide wheel through the first bevel gear group.

The bottom end of the abutting cam intermittently abuts against the canal plowshare, so that the canal plowshare is lifted and lowered inside the grass, thereby preventing the hardened soil in the grass from affecting the progress of the canal plowshare operation.

[0020] The lifting platform drives the transmission shaft to lift the second bevel gear group connected to the retaining frame, and then the second bevel gear group slides on the outer wall of the driving shaft, so that the channel opening plow head can be driven by the rotation of the travel guide wheel to cooperate with the elastically connected positioning plow seat above to perform channel opening operations under different heights of the buried net operation.

[0021] 3. The metal mesh roll is inserted into the storage net ring frame, and the end of the metal mesh is pulled into the net entry bracket.

[0022] The transmission shaft is driven by the third bevel gear group to rotate the conveying shaft connected to the second pulley assembly, and the conveying shaft drives the guide tube inside the peristaltic guide disk to carry out negative pressure conveying of the medicine liquid, so that the medicine liquid inside the control agent box is conveyed to the spray assembly through the peristaltic guide disk, so that the spray assembly sprays the medicine liquid onto the surface of the unwound metal mesh, and the dual prevention and control of rodent damage is achieved through the burial of the metal mesh and the combination of the medicine liquid.

[0023] 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.

[0024] 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.
