[0023] When the film laying width needs to be adjusted, the fastening bolts can be loosened, and the length of the inner rods 2 on both sides inserted into the outer rod 1 can be adjusted so that the distance between the two clamping rollers 36 is adjusted to the predetermined distance. Then, the fastening bolts are tightened again. Holding the disc fixed to one end of the insertion shaft 38, pull it outward. At this time, the distance between the clamping rollers 36 on both sides increases, the second spring 39 is compressed, and the film roll of the corresponding specification is placed in the appropriate position. Loosen the disc, and the clamping rollers 36 on both sides move towards each other under the action of the second spring 39 until the clamping rollers 36 are inserted into one end of the film roll. This utility model can flexibly adjust the film laying width according to actual needs, facilitate the disassembly and assembly of the film roll, and is flexible and practical.

[0024] The second connecting plate 35 and the side plate 3 are fastened together by bolts; the second connecting plate 35 has a strip hole for the bolt to pass through. The installation height of the second connecting plate 35 relative to the side plate 3 can be adjusted through the strip hole, thereby adjusting the height of the film roll off the ground, so as to adapt to flat ground and ridging.

[0025] A second sleeve is fixed to the outer wall of the rear end of each of the two side plates 3; a rotating shaft 19 is inserted into each of the second sleeves; a positioning plate 20 is fixed to one end of each of the two rotating shafts 19; the positioning plate 20 fits against the outer wall of the side plate 3; several positioning holes 21 are provided on the side plate 3 in an arc shape with the rotating shaft 19 as the center; the positioning plate 20 is fastened to the side plate 3 by bolts; the two ends of the bushing 22 are respectively fitted onto the two rotating shafts 19; several insertion holes 23 are provided at equal intervals on the bushing 22 and the two rotating shafts 19; the bushing 22 and the rotating shaft 19 are connected by a cylindrical pin passing through them and a cotter pin, or they can be fixed by wrapping with wire, etc.; mounting plates 24 are fixed to the side walls of both ends of the bushing 22; a first connecting plate 25 is installed on each mounting plate 24; a pressure roller 26 is rotatably installed between the two first connecting plates 25.

When the device moves forward, the trenching shovel 11 can perform trenching operations on both sides.

[0029] A soil covering assembly is also installed on the rear side of the movable outer pipe 6. When the installation position of the movable outer pipe 6 is adjusted, the soil covering assembly can be moved together, thereby adjusting the spacing between the two soil covering assemblies to adapt to different membrane laying widths.

When the device moves forward, the soil covering wheel 18 can push the soil from the trench back and press the two sides of the membrane under the soil.

[0031] Both second insertion rods 13 have a pressure roller 14 rotatably mounted on their lower parts; the pressure roller 14 is located in front of the covering roller 18. The pressure roller 14 can flatten both sides of the film to prevent the film from being not pressed under the soil when the covering roller 18 covers the soil.

[0032] The front side of the lower rod 5 is fixed with a connecting part for connecting to an external traction device. During operation, this device is mounted on a traction machine via the connecting part, and the traction machine drives the device to move.

[0033] The working principle of this utility model:

[0034] In use, install this device onto the traction machine. Loosen the fastening bolts according to the required film-laying width, and adjust the length of the inner rods 2 inserted into the outer rods 1 on both sides, thereby adjusting the distance between the two clamping rollers 36 to the predetermined distance. Then, retighten the fastening bolts. Hold the disc fixed to one end of the insertion shaft 38 and pull it outwards. At this time, the distance between the clamping rollers 36 on both sides increases, the second spring 39 is compressed, and the corresponding specification film roll is placed in the appropriate position. Loosen the disc, and the clamping rollers 36 on both sides move towards each other under the action of the second spring 39 until the clamping rollers 36 are inserted into one end of the film roll.
