Self-driven plug-in type centrifugal seeding device

Abstract

The invention discloses a self-driven plug-in type centrifugal seeding device and aims to provide a self-driven plug-in type centrifugal seeding device which has the advantages of high reliability, high production efficiency and high operating quality. The self-driven plug-in type centrifugal seeding device consists of a supporting shaft, a width disc, a cam bracket, a cam, a return spring, a plurality of seed metering bodies, a flexible seed tube, a revolving shell, a seed filling tube, a seed metering spoon, a positioning pin and an arc-shaped positioning hole, wherein the supporting shaft is horizontally fixed on a seeder rack, the side end face of the revolving shell is coupled with the width disc in a matching way and is supported on the end of the supporting shaft in a rotating way, the other side end of the revolving shell is supported on the horizontal section of the seed filling tube in a rotating way; and at least six seed metering bodies are uniformly distributed in the radial direction and are embedded in the revolving shell, the root part of the seed metering spoon is hinged with the outer ends of the seed metering bodies, and the inner tongue body of the seed metering spoon is hinged with the outer end of the flexible seed tube. The invention is applicable to the precise seeding of inter-tilled crops.

Description

technical field [0001] The invention relates to a sowing part in an agricultural machine, in particular to a self-driven inserting type centrifugal seeder. Background technique [0002] The row crop seeder is mainly used for sowing operations of row crops such as corn and soybeans. Especially in recent years, due to the continuous increase in the price of high-quality seeds, the reduction of seedling management costs during the seedling period, and the development of cultivation techniques for increasing production and efficiency, the mechanized precision seeding technology has been widely promoted and applied. The representative models are mainly Mechanical precision seeder. This model adopts socket brush type seed metering device, which is driven by the ground wheel of the planter. The driving sprocket is installed on the ground wheel shaft, and drives the sprocket on the seed metering device shaft through the chain. Drive the seed meter to work. The technical solution ...

AI Technical Summary

Problems solved by technology

There are still deficiencies, first, the transmission mechanism is complicated, and the reliability of the operation is reduced. If the field sundries are stirred in again, the transmission system will fail; And the sprocket wheel on the seed metering device shaft, the conversion operation is very time-consuming and inconvenient, which reduces the production efficiency; the third is that the rotating agitation of the socket eye wheel of the mechanical socket brush type seed metering device is easy to cause the seeds to be broken, so that the quality of the sowing operation is not good. ideal

It can be seen that there are problems of poor reliability, low production efficiency and unsatisfactory operation quality.
