[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0013] See also Figure 1-2 The utility model provides a technical solution: a film covering device for agricultural planting, including a frame, the frame including mutually parallel beams a1 and beams b3, side plates 2 are connected between the two ends of the beams a1 and b3, the beams b3 are located in front of the frame, and an open card slot 14 is provided on the upper side of the side plate 2, the card slot 14 is used for clamping the film roll, the beams a1 and b3 are both square tube structures, and a mounting seat is fixedly connected to the beam a1, and the mounting seat is used to dock with a tractor.
[0014] Symmetrical guide sleeves are fixedly installed on the left and right sides of the crossbeam b3, and the guide sleeves are installed with upright posts 4 that can be adjusted up and down. The lower end of the upright posts 4 is installed with a soil covering plate 5 that is inclined at a certain angle to the walking direction. The side of the side plate 2 is hingedly installed with a plate-shaped swing arm a6, and a film pressing roller 11 is rotatably connected between the front ends of the two swing arms a6. The side plate 2 is provided with an arc-shaped limiting hole 12, and the swing arm a6 is fixedly installed with a pin, which passes through the limiting hole 12 and is slidably connected thereto. A tension spring 7 is connected between the front part of the swing arm a6 and the side plate 2, and the tension spring 7 pulls the swing arm a6 to swing downward, so that the film pressing roller 11 applies pressure downward, and when rolling over a raised soil block, the swing arm a6 can swing upward for buffering.
[0015] The inner side of the side plate 2 is hingedly mounted with a swing arm b9, and a sponge pressure wheel 8 is mounted on the inner side of the swing arm b9. The distance between the two sponge pressure wheels 8 is smaller than the distance between the two soil covering plates 5. The soil covering plates 5 are used to press soil on both sides of the film. The sponge pressure wheel 8 is light in weight and low in hardness. When rolling the film, the film can be prevented from being crushed. The inner side of the side plate 2 is fixedly connected with a mounting plate, and the mounting plate is slidably connected with a vertically penetrating guide rod 10. The lower part of the guide rod 10 is connected to the mounting plate with a thrust spring 13. The thrust spring 13 applies a downward thrust to the swing arm b9 through the guide rod 10. When the swing arm b9 swings upward, it needs to overcome the elastic force of the spring 13.
[0016] Working principle: The device is towed and moved by a tractor. The film roll is placed between two slots 14. The exiting end of the film roll passes through the film pressing roller 11 and the sponge pressing wheel 8 in turn. The sponge pressing wheel 8 rolls on the film to cover it. Then the covering plate 5 turns the soil to both sides of the film for covering. The elastic pressing method is adopted, and the sponge pressing wheel 8 can reduce the damage to the film.
