[0048] Secondly, the multi-section transmission on the soil turning shaft 21 indirectly drives the film covering shaft 5 through the transfer shaft 4, and the film covering shaft 5 rotates synchronously with the soil turning shaft 21 to start the film covering operation. The edge pressers 6 on both sides of the film covering shaft 5 press the edges of the film into the soil through the horn-shaped edge pressing corners 61, so as to ensure that the film is fixed on the soil surface and prevent wind blowing or external interference.

[0050] The transmission stroke is reduced by the transfer shaft 4 and the transmission belt 41 system of the device through multiple transmission sections, ensuring the orderly operation of the soil turning, seeding and film covering operations. The whole process is efficient and orderly, and the integrated operation of soil turning, seeding, film covering and edge pressing is completed.
