A kind of crop seeding film

Abstract

Provided are a crop sowing membrane and a membrane preparation device. The crop sowing membrane comprises two layers of degradable membranes connected with each other. A plurality of holding cavities are uniformly distributed between the two layers of degradable membranes. Each holding cavity holds seeds, fertilizer, and pesticide. The crop sowing membrane is advantaged by saving manpower and cost, having no pollution, saving water, saving fertilizer, being beneficial for increasing production, and being easy to popularize. The membrane preparation device comprises a rack, a first membrane placing roller, a second membrane placing roller, and a membrane collecting roller. The membrane collecting roller is connected with a first rotation driving assembly. A material aggregating and dropping hopper is above the first degradable membrane. The material aggregating and dropping hopper is provided with a plurality of material aggregating and dropping channels. Two sets of laying-off devices are arranged above the material aggregating and dropping hopper. The rack is also provided with a steering roller and a hot-press device, making the second degradable membrane fits the first degradable membrane. The steering roller and the material aggregating and dropping hopper are arranged along the motion direction of the first degradable membrane in sequence. The membrane preparation device is advantaged by simple structure, low manufacturing cost, high production efficiency, and high automation degree.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a crop seeding film and film-making equipment. Background technique [0002] At present, most crops are cultivated first and then transplanted. From seedling raising to transplanting is the most expensive part of the crop cultivation process. It has problems such as high labor intensity, high labor cost, low economic benefits, etc., and also wastes seedlings and seedlings. Therefore, the aspect of raising seedlings is a difficulty that the agricultural revolution has not overcome. Although there are rice throwing technology and rice transplanters, the status quo has not been fundamentally changed. Among them, the technology of throwing seedlings reduces the labor intensity to a certain extent, but the transportation and throwing of seedlings are insurmountable problems, and the labor intensity is still too high, and many young people are reluctant to do it; Therefore,...

AI Technical Summary

Problems solved by technology

Among them, the seedling throwing technology has reduced the labor intensity to a certain extent, but the lifting and transportation of the seedlings and the throwing of the seedlings are both insurmountable problems. The labor intensity is still too high, and many young people are unwilling to do it; Therefore, it is impossible to ensure that the seeds in each hole are uniform, and the seedlings grown are also different in strength and thinness; it is also impossible to ensure the uniformity of the seedlings when throwing seedlings. Regularity, farmers can't get off the ground even when they go to the field, and it also affects lighting and production

The rice transplanter only reduces the labor intensity of the farmers, but does not fundamentally solve the problem, and its cost is high, the applicability is poor, the seedlings are damaged, the popularity rate is low, and it also consumes a large amount of national agricultural machinery subsidies.

[0003] Nowadays, due to the large number of young and middle-aged farmers in rural areas entering the city, only the old, weak, sick and disabled are left in the countryside. The phenomenon of changing double-cropping rice to single-cropping rice, sowing and sowing, and even abandonment is serious. In some rural areas, the government plows the fields and raises seedlings intensively, and farmers are only responsible for transplanting and management. , but there are still phenomena of abandonment and double reform, which seriously restrict the development of agriculture and threaten national food security.
