Abstract

A synchronous-reseeding seed-metering device for seeding absence during seed sowing is disclosed and belongs to the field of agricultural machines. The device comprises a reseeding indent roller, a power transmission sleeve the external end surface of which is provided with a boss, a clutch sleeve the inner side surface of which is provided with detent teeth, a pressure spring, a driving shaft the end surface of which is provided with detent teeth, a ratchet wheel A the inner side surface of which is provided with a boss, a reseeding control shaft, a rocker arm, a reseeding control arm and a tension spring, or comprises a reseeding indent roller, a cam pedestal, a power transmission column, an inner tooth driving sleeve, arc cams, cam rocker arms, cam rocker arm tension springs, a ratchet wheel B, a reseeding control shaft, a rocker arm, a reseeding control arm and a tension spring .The device achieves synchronous reseeding for seeding absence during seed sowing by indent roller type seed-metering devices, provides machine and tool guarantees for popularization and application of a high-density corn planting agricultural technology, and is characterized by a novel and reasonable structure, good working quality, a low seeding absence rate and reliable using.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical seed-discharging roller-type seed metering device. Background technique [0002] The socket roller seed metering device is a traditional seed metering device suitable for corn and soybean sowing operations developed in the late 1980s. The device can sow single rows of soybeans, single rows of corn, or double rows of corn on large ridges. Operation, because of its simple structure, low cost, and performance that can still meet the production requirements, it has been used in northern China, especially in Northeast China. However, with the improvement of agronomic technology requirements, more and more attention has been paid to the index of the missed sowing rate of the seed meter, especially the promotion of high-density corn planting agronomy, and the number of seedlings per unit area has increased significantly. How to reduce the problem of missed sowing of the seed m...
