Description

Technical Field

[0001] The present application relates to the technical field of agricultural equipment, and in particular to a plateau rapeseed breeding film coating device and method. Background Art

[0002] Rapeseed breeding refers to the process of improving and enhancing rapeseed yield, quality, resistance and other characteristics by selecting and cultivating rapeseed varieties with excellent traits. By selecting and screening a large number of rapeseed germplasm resources, individuals with excellent traits are selected for mating, and selected from generation to generation, excellent varieties are finally cultivated. When breeding rapeseed, it is necessary to cover it with film to improve the growth environment of rapeseed, promote the growth and development of rapeseed, and achieve the purpose of increasing yield and improving quality. Covering can increase soil temperature, maintain soil moisture, improve photosynthetic efficiency, increase photosynthesis, promote plant growth and nutrient accumulation, and inhibit weed growth.

[0003] For example, in the existing Chinese patent with the publication number CN212035154U, a film covering device for agricultural planting is disclosed, which includes a frame and a push frame, a walking wheel is fixed at the lower end of the frame, a front support seat, a rear support seat and a push frame are fixed to the upper end surface of the frame, a first bearing seat is installed on it, a first connecting sleeve is installed inside the first bearing seat, a moving block is slidably installed inside the rear support seat, a second bearing seat is fixedly installed on the front side wall of the moving block, a second connecting sleeve is installed inside the second bearing seat, a rotating shaft is installed between the first connecting sleeve and the second connecting sleeve, and a ground film is wound on the outer wall of the rotating shaft. Through the above-mentioned prior art, after the film covering is completed, the pull rod is pulled by hand, and the wire rope will pull the rectangular frame to move to the left along the inside of the U-shaped groove, and the cutter will move to the left with the rectangular frame, so that the unfolded ground film can be cut off. The operation is simple, and there is no need for farmers to hold a blade and bend down to cut the ground film, which reduces the labor degree of farmers and has high film covering efficiency.

[0004] However, the above prior art has the following technical defects:

[0005] The above-mentioned existing technology can only achieve the effect of eliminating the need for operators to bend down to cut the film after the film covering is completed. During the film covering process, the planting ground is often uneven. When encountering raised areas, the above-mentioned device is difficult to respond in time, and there is no corresponding device for adjusting the height of the ground film or the frame, so that the overall film covering work cannot be completed smoothly and conveniently; secondly, after film covering, it is usually necessary to cover both sides of the film with crushed soil to complete the entire film covering work, and the above-mentioned device is not equipped with a corresponding device for preparing both sides of the film after film covering. Subsequently, the operator is required to compact and prepare both sides of the film again, which increases the working time of the operator and reduces the efficiency of the film covering work.

[0006] Based on this, on the basis of the existing agricultural planting film covering equipment, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention
