[0002] Film mulching seeding technology has been widely used in modern agricultural production. This technology can significantly increase soil water storage, reduce water evaporation, effectively reduce water loss to improve the soil environment, and then promote the healthy growth of crops and increase crop yields. The multifunctional film mulching seeder developed on this basis integrates multiple functions such as ridge formation, fertilization, film mulching, laying drip irrigation pipes, sowing and suppression, which saves labor and production costs to a great extent; but the existing equipment needs to rely on manual disconnection of the film after the film mulching work of each ridge is completed, which not only increases the workload and labor intensity of the staff. Summary of the invention

[0003] The purpose of the present invention is to provide a film cutter for a film-covering seeder, which can automatically cut the film when the film-covering operation is finished, thereby improving the mechanization degree of the seeding operation, reducing the workload of the staff, and improving the working efficiency of the film-covering seeder.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0005] A film cutting device for a film covering seeding machine comprises a main frame, both sides of the main frame are fixedly connected to a first connecting rod, the top of the first connecting rod is rotatably connected to a second connecting rod, a mounting frame is fixedly connected between two ends of the second connecting rods away from the first connecting rod, a plurality of film cutting claws are arranged at the bottom of the mounting frame, a third connecting rod is rotatably connected to the bottom of the first connecting rod, a film cutting frame is fixedly connected between two ends of the third connecting rods away from the first connecting rod, a film pressing roller is arranged between the film cutting frame and the main frame, and both ends of the film pressing roller can be rotatably connected to the third connecting rod On the connecting rod, a fourth connecting rod is provided between the second connecting rod and the third connecting rod, the bottom of the fourth connecting rod is rotatably connected to the third connecting rod, the middle of the fourth connecting rod is rotatably connected to the second connecting rod, a fifth connecting rod is provided between the fourth connecting rod and the mounting frame, the two ends of the fifth connecting rod are respectively rotatably connected to the top of the fourth connecting rod and the mounting frame, a fixing rod is fixedly connected to the main frame, both ends of the fixing rod are rotatably connected to connecting plates, a film pressing wheel is rotatably provided on the opposite side of the two connecting plates, and a loading rod is fixedly connected to the middle of the main frame.

[0006] Furthermore, the edge width of the laminating wheel body is greater than the middle width of the wheel body.

[0007] Furthermore, the main frame, the first connecting rod, the second connecting rod, the mounting frame, the film cutting claw, the third connecting rod, the film cutting frame, the film pressing roller, the fourth connecting rod, the fifth connecting rod, the fixing rod, the connecting plate, the film pressing wheel and the loading rod are all made of alloy steel.

[0008] The beneficial effects of the present invention are:

[0009] The device of the present invention is installed on the seeder through a loading rod. When the combined seeder is lowered, the film pressing roller and the film pressing wheel will contact the soil first, and the film passes through the film breaking frame, which applies tension to the film. When the seeder is in operation, the film is laid on the soil through the film breaking frame, and the film pressing roller plays a role in compacting the film and the soil, and the film pressing wheel presses the films on both sides into the soil. When the seeder reaches the end of the farmland, the seeder lifts the loading rod. At this time, as the loading rod is lifted, the film breaking claw closes downward with the film breaking frame under the mutual cooperation of the first connecting rod, the second connecting rod, the third connecting rod, the fourth connecting rod and the fifth connecting rod, so as to cut the film between the film breaking claw and the film breaking frame, thereby achieving the effect of film breaking. The present invention automatically breaks the film at the end of the film covering operation, thereby improving the mechanization degree of the seeding operation, reducing the workload of the staff, and improving the working efficiency of the film covering seeder.
