Precision grain drill with seedling-cultivation plate of rice

Abstract

The invention discloses a rice seedling raising precision planting machine with a rice seedling disk, which comprises a frame (1), a rice seedling disk limit mechanism (2) for limiting the position of the rice seedling disk, a bottom soil laying device (5) and a precision planting device (8) which are sequentially arranged on the front section of the frame (1), a chain-type strip conveying mechanism (16) which is arranged inside the frame (1) for conveying the rice seedling disk and an air compressor (3) which is arranged at the underside of the frame (1) and connected with the precision planting device (8) and a main motor (14) which is arranged at the underside of the frame (1) and connected with all mechanisms. The rice seedling raising precision planting machine with the rice seedling disk has the advantages of simple structure, good planting performance, reliable work and high productivity.

Description

technical field [0001] The invention relates to a seeding machine, in particular to a precision seeding machine for rice seedling tray seedling raising. Background technique [0002] With the continuous development and improvement of rice varieties, rice planting methods have presented various forms. In order to adapt to the new rice planting methods, rice planting mechanization has also developed greatly in our country, among which rice transplanting mechanization is the main one, so the development of rice seedling raising Machinery adapted to the development of rice production. Although the rice seedling-raising techniques of different varieties are basically similar, that is, the operations of laying the bottom soil, sowing, covering soil, cleaning, and watering are used; grains / hole (grid), hybrid rice seedlings usually require 3 to 5 grains / hole (grid), while super rice requires 1 to 2 plants / hole (grid). Therefore, with the continuous development and improvement of ...

AI Technical Summary

Problems solved by technology

At present, vibrating or pneumatic seeders are mainly used. The vibrating seed metering device has a simple structure and less damage to the seeds, which can meet the precision and small amount of sowing of hybrid rice, but the seeding accuracy is not high, and the existing seed metering devices cannot meet the precision requirements. Seeding requirements, the pneumatic seed metering device has good seeding accuracy, but has the characteristics of high price, clogged suction holes, and low productivity.

In addition, the existing sowing assembly line is generally only suitable for a single type of seedling tray, and the adjustability of the sowing rate is relatively poor. It is difficult to adapt to the sowing requirements of different types of seedling trays and the sowing accuracy requirements of different rice varieties.
