Description

Technical Field

[0001] The utility model relates to the technical field of agriculture, in particular to a plastic film laying device for agricultural vegetable planting. Background Technique

[0002] Generally, plastic film mulching is carried out in greenhouse vegetable planting, which is abbreviated as film mulching planting. Film mulching planting can sow in advance or cultivate out of season. The function of plastic film mulching is to increase the soil temperature, and can also effectively prevent the evaporation of soil moisture, so that the moisture is stored in the soil for a long time. After the vegetables are planted, they are more likely to slow down seedlings under higher moisture conditions. The plastic film can also reduce the occurrence of various diseases. Because the humidity in the greenhouse is very high, it is easy to cause low-temperature and high-humidity diseases such as gray mold, phytophthora blight, and soft rot. Secondly, after the plastic film is covered, the soil is not easy to harden, has good air permeability, and can accelerate the decomposition of organic matter and the nitrification of nitrogen. The temperature increase effect of the plastic film is also conducive to the activities of microorganisms in the soil, promoting the decomposition of organic matter and improving soil fertility. The covering of the plastic film also has the effect of inhibiting weed growth.

[0003] At present, a Chinese patent discloses a plastic film laying device for agricultural vegetable planting, with the application number 2023201065703. Through the combined use of the adjustable support component and the soil covering component, the plastic film to be laid can be sleeved on the telescopic rod two of the adjustable support component, and then the plastic film can be pulled and fixed on the ground surface, so that the plastic film is placed under the two pressing wheels on the soil covering component. Then, soil blocks are added to the weight box on the soil covering component, so that the weight box presses the two soil shoveling plates to insert into the soil to shovel and turn up the soil to cover both ends of the plastic film. Then, a person pulls the device forward to move it, so that the device can not only lay the plastic film but also cover and press the soil at both ends of the laid plastic film. In this way, the effect of laying the plastic film by one person pulling can be achieved, making the operation of the device not only simple but also improving the laying efficiency. Then, through the telescopic adjustment component, the plastic film to be laid can be supported and clamped. Secondly, through the action of the telescopic rod two, plastic films of different sizes can be sleeved for laying, so that the application of the device to the plastic film is not single and can cope with plastic films of different sizes for laying.

[0004] Combined with the above disclosed technical solution, due to the possible unevenness of the ground surface, when the soil shoveling plate shovels and covers the soil on the plastic film, the situation of unevenness will occur, resulting in the failure of some plastic film surfaces to be covered with soil, leading to air leakage in the plastic film laying, thus affecting the heat preservation and moisture preservation effects of the plastic film. Therefore, we propose a plastic film laying device for agricultural vegetable planting. Content of the Utility Model

[0005] To solve the technical problems of plastic film laying, the utility model provides a plastic film laying device for agricultural vegetable planting.

[0006] The present utility model is implemented by the following technical solutions: A device for laying plastic film on agricultural vegetable planting land, comprising a frame, a bidirectional lead screw, and two connecting components. The frame is U-shaped, and a perforation is provided at the bottom inside the frame. One side of the frame is rotatably connected to a transfer rod.

[0007] The bidirectional lead screw has both ends rotatably connected to the frame. On both sides of the surface of the bidirectional lead screw, there are movable frames threadedly connected. At the top and bottom of the movable frame, an elastic clip and a telescopic rotating shaft are respectively fixedly connected. Inside the elastic clip, a plastic film covering component is penetrated.

[0008] The two connecting components are fixedly connected to the side surface of the movable frame. One end of the connecting component is fixedly connected to a collection box. One side of the collection box is fixedly communicated with a soil shovel plate. On both opposite sides of the two collection boxes, there is a discharge pipe. One end of the discharge pipe is rotatably connected to a pressing wheel, and holes are provided at the bottom of the discharge pipe.

[0009] As a further improvement of the above solution, the plastic film covering component includes two fixed seats, a film winding cylinder, and a rotating rod. Inside one of the fixed seats, there is a rotating seat rotatably connected. One end of the film winding cylinder is rotatably connected inside the rotating seat. One end of the film winding cylinder is abutted between the fixed blocks of the other fixed seat through a card slot. One end of the film winding cylinder abuts against a rotating rod, and one end of the rotating rod is rotatably connected to the inner wall of the frame, making it convenient to place the plastic film on the film winding cylinder.

[0010] As a further improvement of the above solution, the bottom of the movable frame passes through the perforation provided inside the frame and is connected to the telescopic rotating shaft, so that the movable frame drives the telescopic rotating shaft to retract and extend.

[0011] As a further improvement of the above solution, at both ends of the telescopic rotating shaft, there are moving wheels installed through bearings. Inside one of the moving wheels, there is an installation groove, and a rotating column is slidably connected inside the installation groove. One end of the rotating column is connected to the plastic film covering component through a transmission belt, so that the moving wheel drives the film winding cylinder to rotate.

[0012] As a further improvement of the above solution, the connecting component includes an L-shaped rod. Inside the L-shaped rod, there is a lead screw threadedly connected. On the surface of the lead screw, there is a moving rod threadedly connected. One end of the moving rod is fixedly connected to the collection box, which can adjust the height of the collection box.

[0013] As a further improvement of the above solution, an arc-shaped counterweight block is fixedly connected inside the collection box, which can counterweight the collection box and at the same time guide the soil.

[0014] As a further improvement of the above solution, one side of the pressing wheel is fixedly connected to a spiral blade. One end of the spiral blade penetrates into the collection box, so that the rotation of the pressing wheel drives the spiral blade to rotate.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The utility model uses a shovel board, a collecting box, a spiral blade and a pressure wheel. After the shovel board shovels the soil into the collecting box, the spiral blade is driven to rotate by the pressure wheel, so that the soil in the collecting box can be evenly transported to the surface of the ground film, thereby solving the problem of uneven soil coverage on the surface of the ground film and improving the sealing of the ground film coverage.

[0017] 2. The utility model uses a moving wheel, a rotating column, a rotating rod and a film rolling drum, so that the moving wheel rotates to drive the rotating column, and the rotation of the rotating column drives the transmission belt to drive the rotating rod to rotate, and the rotation of the rotating rod drives the film rolling drum to rotate. When the device moves, the film rolling drum can be driven to rotate, and the ground film sleeved on the outside of the film rolling drum can be retracted and released, preventing the ground film from being torn by a large pulling force when it is retracted and released, thereby reducing the damage rate of the ground film.
