Description

Technical Field

[0001] The utility model belongs to the technical field of film covering devices, and particularly relates to a film covering device for agricultural planting. Background Art

[0002] Agricultural film covering refers to a technology of using film materials to cover soil, crops or facilities in agricultural production. It can improve soil conditions, promote plant growth, increase crop yields and protect crops from adverse weather conditions. By covering the film in the planting area, the growth conditions can be optimized and environmental stress can be reduced, the yield and quality of crops can be improved, water evaporation and weed growth can be reduced, thus saving water resources and labor, improving soil temperature and humidity, and extending the planting and growth cycle of crops;

[0003] A film covering device for agricultural planting proposed in the patent with the publication number of CN 218072728 U includes a film covering device frame, a film covering device body, a film covering device lifting frame and a film tube. The film covering device body is fixedly connected to the outside of the film covering device frame. A control lead screw is rotatably connected at the top position inside the film covering device body. In the utility model, by setting the film covering device lifting frame, when adjusting the height position between the film tube and the planting soil, the lead screw control motor drives the control lead screw to rotate. Under the action of the thread structures on both sides of the control lead screw in opposite directions, the lifting control nuts on both sides of the control lead screw pull the lifting control rods, so that the lifting control rods drive the film covering device lifting frame to move in the vertical direction. By adjusting the position of the film covering device lifting frame, the position between the film tube at the lower end of the film covering device lifting frame and the planting soil can be adjusted, so that the position of the film tube can be automatically adjusted according to the height of different planting soils;

[0004] This film covering device winds the protective film on the rotating cylinder and allows the trolley to carry the rotating cylinder and move on the planting area. However, this device only provides the functions of automatic film covering and height adjustment. In actual film covering operations, since the widths of the planted fields are different, this device cannot adjust the wheel spacing of the moving device, so it cannot adapt to the film covering operations of fields with different widths. Moreover, after the film covering operation is completed, an additional tool is needed to cut the protective film, and the operation is rather cumbersome.

[0005] Therefore, those skilled in the art have proposed a film covering device for agricultural planting to solve the problems raised in the background art.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of the utility model. Therefore, it may include prior art that is not known to ordinary skilled persons in this field. Summary of the Utility Model
