Description

Technical Field

[0001] The utility model relates to the technical field of laying ground films for crop planting, in particular to a device for laying ground films for crop planting. Background Art

[0002] Crop cultivation refers to the process by which humans, through a series of agricultural production activities such as tillage, sowing, and management, enable crops to grow and develop in farmland, ultimately achieving harvest, based on their ecological adaptability and production needs. This process involves selecting appropriate crop types, suitable land conditions, rational planting methods, and scientific management measures. Crop types: Based on their different growth cycles, uses, and ecological needs, crops can be divided into food crops (such as wheat, rice, and corn), cash crops (such as cotton, tobacco, and sugar crops), oil crops (such as rapeseed and soybeans), vegetable crops, and fruit crops. Cropping system: refers to the rational arrangement of the time and space layout of crop planting within a certain area according to natural conditions, economic conditions, and social needs, and includes crop rotation, continuous cropping, intercropping, and interplanting. Ground film, also known as ground cover film, is a plastic film used in agricultural production. It is mainly applied to the soil surface to improve the crop growth environment and increase agricultural production efficiency. The use of ground film is an important part of modern agricultural technology and is widely used in the cultivation of vegetables, fruits, food crops, and other crops.

[0003] The patent document with application number CN202221361594.5 discloses a device for laying ground film for agricultural planting, which "includes two mounting rods, both ends of the mounting rods are fixedly installed with sleeves; the inner sliding sleeve of the sleeve is connected with a stabilizing rod and is locked by a fastening bolt, and the stabilizing rod is slidably connected with a pull rod; the mounting rod is installed with a roller, and the sleeve is installed with a guide wheel; the side of the mounting rod is fixedly installed with a right-angle block, and the right-angle block is provided with a mounting groove; the sleeve is fixedly installed with a shovel. The utility model proposes a device for laying ground film for agricultural planting, which is convenient for changing the right angle by sliding the sleeve and the stabilizing rod. The distance between the blocks is determined, and the rolled ground film is placed. A shovel is provided to shovel the soil. After the ground film is laid, the shovel covers the soil to the edge of the ground film, which is convenient for one person to operate. Based on the search of the above patents and in combination with the agricultural crop planting ground film laying device in the prior art, it is found that the agricultural crop planting ground film laying device has few functions when used, especially in fixing the ground film.
