Flue-cured tobacco mulching film row spacing marking device

Abstract

The invention discloses a flue-cured tobacco mulching film row spacing marking device comprising a rack, a motor group and a roller shaft assembly, wherein the roller shaft assembly comprises a guide roller group, a steering roller group and a reversing roller group, the marking device further comprises a printing assembly, the printing assembly comprises a marking roller and a pressing roller, the marking roller is externally tangent to the pressing roller, the marking roller is connected with a printing ink box, and a printing ink scraping knife is arranged on the outer side of the marking roller; and the flue-cured tobacco mulching film row spacing marking device disclosed by the invention marks the common polyethylene (PE) agricultural mulching film by printing at one time online to greatly relieve the labor intensity of farmers and reduce 2 / 3 of labors, the device can be used for accurately and clearly marking the mulching film so as to improve the accuracy of the line spacing and the row spacing during the transplanting process, the location of the row spacing is accurate to guarantee the plants to uniformly grow, so that the fertilization uniformity is large during the fertilization process and the non-fertilization phenomenon is unlikely to happen, thereby further improving the agricultural yield and the crop quality.

Description

technical field [0001] The invention relates to the field of agricultural plastic mulches, in particular to a device for marking the plant-to-plant spacing of flue-cured tobacco mulch films. Background technique [0002] Plastic film mulching cultivation technology is a relatively conventional cultivation technology popularized and applied in crop production. With the development of plastic industry, especially the emergence of agricultural plastic film, some industrially developed countries use plastic film to cover the ground for vegetable and other agricultural production. , forest crops have achieved good results. [0003] At present, polyethylene (PE) agricultural mulch has been widely used in the cultivation of agricultural and forestry plants and can increase the yield of crops (20-30%). The effect of growth. It can also improve the grade of tobacco leaves in tobacco planting, which is very popular among agriculture and tobacco farmers. However, the existing polyeth...

AI Technical Summary

Problems solved by technology

It can also improve the grade of tobacco leaves in tobacco planting, which is very popular among agriculture and tobacco farmers. However, the existing polyethylene (PE) agricultural mulch films are unmarked white films or colored films, which cannot be used to determine plant planting. row and plant spacing

The traditional way is to manually mark on the film, which not only cannot mark accurately, but also wastes time, manpower and money. The irregular spacing of rows and plants will affect the photosynthesis and ventilation of plants, and also affect the further increase of yield.

[0004] Because polyethylene (PE) agricultural mulch film is ultra-wide and ultra-thin, and its tension is difficult to control, it cannot be printed on the printing machine for the second time like ordinary packaging film. It can only be printed online at high speed (90-120 m / min) and Slitting, there is no professional polyethylene (PE) agricultural mulch printing machine on the market
