Description

Film-coating and hole-punching integrated equipment for flue-cured tobacco

Technical Field

The invention relates to the technical field of tobacco planting, in particular to a film covering and hole punching integrated device for flue-cured tobacco.

Background

The mulching cultivation is a widely applied technology in flue-cured tobacco production in China, mulching films can effectively improve the ground temperature, keep moisture, improve the ecological conditions of tobacco field soil, promote the early growth and fast growth of tobacco seedlings and the late mature and yellow falling of tobacco plants, and have important effects on improving the yield and quality of tobacco leaves and increasing the benefits of tobacco growers. The concrete operation of flue-cured tobacco transplanting comprises the procedures of land preparation, ridging, film covering, hole digging, transplanting and the like. At present, film covering and hole digging for flue-cured tobacco transplanting are two processes and are respectively operated, because a part of tobacco areas (southeast tobacco areas of China) need to be ridged and covered in advance due to rainy weather in the transplanting period, and then hole digging and transplanting are carried out; however, the more important reason may be due to the lack of suitable film-covering and hole-punching integrated machinery, especially in the mainstream production areas of flue-cured tobacco in China, such as Yunnan, Guizhou, Sichuan and the like. Therefore, the research and development of the film covering and hole digging all-in-one machine are very important for promoting modern agriculture mechanization, reducing the cost of agriculture and increasing the income of farmers.

Researchers at home and abroad have made many studies on film-coating and punching machines (hole making machines). For example, Kennco agricultural machinery manufacturing Inc. in the United states developed a semi-automatic on-film hole punch that was capable of simultaneously punching holes in a single or multiple rows of film, but the machine was relatively less automated and less efficient. For another example, the full-automatic duckbilled membrane upward transplanting punching machine capable of adjusting the plant spacing to realize multi-row transplanting is developed by japan jusha corporation, but the machine has a complex structure, high cost and little popularization and application. Recently, Jiangsu university proposes the design of a flue-cured tobacco well cellar type transplanting film covering and hole inserting machine, the technology can realize the automatic well cellar punching function, but the film covering and punching cannot be integrated. In addition, the existing film covering and punching equipment rarely considers the collection and treatment of residual agricultural films in the hole opening process, and the residual agricultural films in soil easily cause environmental pollution, which is also a problem that the existing film covering and punching equipment is not ignored. In conclusion, a suitable tobacco covering and hole punching integrated machine is not developed at present. Therefore, aiming at the problems, the invention designs the flue-cured tobacco film covering and hole digging integrated equipment which can realize the functions of automatically covering the film and opening the hole and digging the hole, and meanwhile, the opened agricultural film is automatically recycled, so that the environmental pollution is less, and the flue-cured tobacco film covering and hole digging integrated equipment has a better application prospect in the technical field of mechanized and efficient transplanting of flue-cured tobacco.
