[0030] Working principle: When in use, install the film cylinder, and flexibly adjust the distance and height of the two soil-pulling discs 8, the two drive wheels 23, and the two soil plow blades 20 to the appropriate position according to different terrain and ridge width requirements, so as to improve the versatility and practicality of the film laying machine. The two soil plow blades 20 are aligned with the two film pressing wheels 12. After firmly grasping the adjustment handle 27 and adjusting the handle 26 to the appropriate position, release it. Insert the key into the main power switch 30 and turn it. Press the drive motor controller switch 31, drive wheel controller switch 32, left wheel drive control switch 35, and right wheel drive control switch 36 respectively to power up the film laying machine. Hold the end of the handle 26 and rotate the speed control handle 28 to move the film laying machine forward. After reaching a suitable speed and holding it for 5 seconds, release the speed control handle 28. During the forward movement of the film laying machine, the soil plow blade 20 opens a trench to form a groove. The film tube installed on the film hanging tube base 4 rotates to lay the film on the soil. Under the action of the two film pressing wheels 12, the two sides of the film fall into the inside of the groove along the edge. Then, the soil pushing disc 8 pushes the soil into the groove to compact the two sides of the film, thus realizing the film laying function. When the field plot is small, press the drive motor controller switch 31 again to disconnect the power of the drive motor controller 34. The soil pushing disc 8 becomes driven, which saves electricity. When the film-laying machine needs to turn left, press the left wheel drive control switch 35 again to de-energize the left drive wheel 23; when the film-laying machine needs to turn right, press the right wheel drive control switch 36 again to de-energize the right drive wheel 23; when you need to stop film-laying, turn the speed control handle 28 slightly and then release it.
