Background
In recent years, as rural labor is rapidly transferred to the third industry, the aging of population is increased and the labor concept of farmers is changed, the labor force of vegetable production is greatly reduced, and the problems of high labor cost, difficult labor use and the like are highlighted. Therefore, mechanization of the whole vegetable production process is an important way to solve the problems and is a necessary way for the development of the vegetable industry. The production of the vegetables relates to a plurality of links such as soil preparation, seeding and seedling raising, field management, harvesting and processing, and the mechanization of the production refers to the whole process of penetrating through the whole vegetable industry chain by using mechanical equipment, so that the production process becomes large-scale, standardized and intensive. The method mainly comprises the following procedures of ditching and ridging, rotary tillage and soil crushing, shaping and compacting, film covering, soil covering, compacting and the like. Because of various vegetable varieties, different vegetable planting agronomic requirements, wide regions and large difference of physical characteristics of soil in China, the traditional finishing floor machine in China is difficult to adapt to the operation requirements of vegetable finishing floor. At present, the soil preparation link of the open vegetable production in China still takes a common rotary cultivator as a main part, and the soil preparation quality is poor; the soil preparation link of facility vegetable production requires more meticulous operation, and it all puts forward very high requirements to technical index such as soil breaking rate, soil compactness, tilling depth stability, ridge surface flatness and straightness accuracy, and especially in the four seasons of the north, the weather is cold area, in order to increase vegetable growth cycle, guarantees that vegetables are listed in advance, in the operation of finishing ground, increases the operation processes such as rectangular pieces of land in a field, shop's membrane, suppression, then punches by the transplanter rupture of membranes and transplants the vegetable seedling, practice verifies, current finishing ground shop membrane machine has following shortcoming: firstly, the film can not be covered with soil uniformly after the film is spread, and the film is easy to be blown or torn by wind; and secondly, when the film is drilled by the transplanter after the film is broken, the holes are punched, the transplanted vegetable seedlings grow and drill out the film, the contact film is easily burned by the film, the contact film needs to be manually shoveled to cover about 1 cm-2 cm, a large amount of labor is consumed, and the farming season is often delayed. Therefore, after the film is spread by the transplanter, the machine tool is required to be provided with a soil covering and compacting device which can simultaneously complete the operations of soil taking, covering and soil layer compacting. At present, most of foreign advanced finishing machines applied in actual production are provided with similar devices, but are not suitable for the agricultural requirements of vegetable planting in the northern area in China, and the foreign advanced finishing machines are high in price, inconvenient to maintain and need to be matched with a tractor with large horsepower, so that the problem of unstable operation performance exists in the actual operation process.
