[0002] A technology widely promoted for winter heat preservation planting of some off-season crops such as vegetables is to cover the cultivated ground with plastic film. After cultivation, using plastic film mulch has the advantages of increasing soil temperature, reducing soil moisture evaporation, and preventing weed growth. The plastic film is usually black PE film or transparent, and there are also green and silver films for ground covering to maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote the growth of plants. Manual film laying has a slow progress, high labor intensity, and high labor cost. Therefore, film laying machines have been widely used.

[0003] The existing film laying machine presses the film material through the soil covering baffles on both sides, and can only achieve side film pressing of the film material. If the film pressing quality is to be ensured, it is necessary to manually use a spade to cover the soil in the middle position of the film material later, which is time-consuming and laborious.

[0034] Among them, the elevator 2 is inclined. One end of the elevator 2 is located above the diversion hopper 3. During the progress of the elevator 2, it lifts the loose soil in front of it. After the soil reaches the highest point, it falls into the diversion hopper 3.

[0035] Among them, a diversion groove 31 is arranged inside the diversion hopper 3. A discharge port 32 is arranged at the bottom of the diversion hopper 3. The discharge port 32 is located in the middle position of the diversion hopper 3. The loose soil falling into the diversion hopper 3 is diverted by the diversion groove 31, concentrated and enters the discharge port 32 located in the middle position, and is discharged through the discharge port 32, falling to the middle position on the surface of the film material to achieve film pressing.

[0036] Among them, the frame 1 includes a cross-frame 13. The diversion hopper 3 is fixedly connected to the cross-frame 13 through a connecting frame 33.

The connection method is simple, and it is convenient to install and disassemble the second soil covering assembly 5, which is beneficial to maintenance.

[0039] Among them, mounting plates 14 are welded and fixed on both the first side frame 11 and the second side frame 12. Notches are formed in the mounting plates 14. The frame 1 is installed and fixed on the film laying machine through the mounting plates 14. The connection between the frame 1 and the film laying machine is detachable. It further includes a collecting and compacting mechanism. The collecting and compacting mechanism includes a baffle 34, an arc-shaped baffle 35, a leakage groove 36 and a conduction port 37.

[0040] Working principle: During use, the film pressing mechanism is installed and fixed on the film laying frame of the film laying machine. The film pressing mechanism moves along with the film laying machine. A film spreading roller and a furrowing opener are installed on the film laying machine. During the process of the film laying machine moving forward, the furrowing opener loosens the soil on both sides. The film spreading roller will automatically roll during the traction to unfold the film material and lay the film material. The film laying machine drives the film pressing mechanism to move. The first soil covering assembly 4 and the second soil covering assembly 5 on both sides drive the loose soil to cover inward through the soil covering wheels 52 in a shape of an eight, pressing the two sides of the film material to achieve side film pressing. At the same time, the conveyor belt 22 of the elevator 2 drives multiple sets of material plates 23 to move at a constant speed under the drive of the motor reducer 24. During the process of the elevator 2 moving forward, the loose soil in front of it is lifted. After the soil reaches the highest point, it falls into the diversion hopper 3 and finally is discharged through the discharge port 32 at the bottom of the diversion hopper 3. The discharged soil falls to the middle position on the surface of the film material, pressing the surface of the film material. During the process of the film laying machine driving the film pressing mechanism to move forward, film pressing on the surface of the film material is realized.

[0041] To improve the effect of covering soil and gathering it in the middle of the film, the central collection of the film is realized through the leakage trough, which facilitates the accumulation of the covering soil along the center of the film. The central part of the film is effectively compacted. The arc-shaped baffle and the conduction port realize the conduction of large particles, stones and sundries, effectively ensuring the smooth covering of the leakage trough on the arc-shaped baffle and preventing the large materials from jamming and blocking the leakage trough during the operation of the machine.
