A combination unit for drought-resistant seeding in dry land

Abstract

The invention discloses a combination unit for drought-resistant sowing in dry land, which comprises a ditching shovel, a suspension frame, a main frame, a seed fertilizer box, a seed potato sorting mechanism, a seed potato box, a ridge scraper, and a soil ridge shaper , Movable support, pressing film wheel mechanism, disc covering mechanism, L-shaped telescopic frame, film roll support, ground wheel, transmission mechanism, seed potato ditch opener and other components. Its advantages are as follows: 1. Under the tractor tractor, the unit can complete ditching, fertilization, sowing, ridging, shaping, film covering, film pressing, soil covering and other operations at one time in the field. 2. Realize the drought-resistant sowing and dry farming agricultural planting mode of ridge-film furrow planting, which greatly improves the drought resistance and yield of crops, and has a significant effect of saving film. 3. The unit is designed as a two-station foldable frame to improve the safety performance of the unit during transportation. 4. Compared with the same type of seeder at home and abroad, its structure is simple, the model is small and flexible, the machine tool is cheap, and it is easy to manufacture and popularize.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a combined unit used for drought-resistant sowing in dry land for field operations. Background technique [0002] Film-covered crop cultivation is a new technology of protected cultivation that is being vigorously promoted. It is used to partially control environmental conditions and create a cultivation method suitable for crop growth. It can promote early maturity, high yield and high quality of crops, and has significant economic benefits. . Film mulching technology was initiated in the 1950s, and was used abroad for horticultural cultivation, vegetables and other crops suitable for small-scale intensive cultivation, and later developed to the cultivation of field crops. The film laying technology has developed from manual film laying to the combined operation of film laying and seeding, that is, laying plastic films on the seedbeds of the well-organized land, and simultaneously sow...

AI Technical Summary

Problems solved by technology

However, these relatively mature potato planters are expensive, have high investment costs, and are complex in structure, and some of them cannot meet the agronomic requirements of planting operations in my country, such as the requirements of ridge row spacing, water point planting, ridge film furrow planting, etc.

[0007] At present, the sowing machinery matched with this technology cannot fully meet its agronomic requirements
