Cereal seed sowing device with detachable elastic rotating seed protection device

Abstract

The invention relates to a grain feed with a detachable elastic rotation seed retaining device; the grain feed mainly consists of a shell of the grain feed, a seed-metering wheel, a seed brushing wheel, a seed filling chamber, a seed control baffle of the seed filling chamber and a seed spout, and is characterized in that the invention further includes the detachable elastic rotation seed retaining device which consists of an elastic seed retaining band, a seed retaining band axis, a tension axis, a bearing and a bracket; the elastic rotation seed retaining device is matched with the seed-metering wheel for work, the seed retaining band is an elastic rubber band with an enclosed structure, one section of the elastic seed retaining band firmly leans on the outer surface of the seed-metering wheel to form a seed retaining zone between the seed brushing wheel and the seed spout in virtue of elasticity thereof. The power that drives the elastic rotation seed retaining band to rotate derives from the friction of the surface of the seed-metering wheel, or the power is transmitted to the seed retaining band axis from the axis of the seed-metering wheel through a gear or a chain so as to realize the rotation.

Description

Technical field: [0001] The invention belongs to a seeding operation device on a sowing implement in agricultural machinery, in particular to a grain metering device with a detachable elastic rotating seed protection device. Background technique: [0002] At present, a fixed seed guard plate is generally used on the hole wheel type metering device. The effect of the seed guard plate is to escort the seeds through the seed protection area to prevent it from falling off from the hole until the seeds enter the seed pipe. When the fixed seed protection plate realizes the above functions, it will inevitably rub the seeds passing through the seed protection area, causing damage to the seeds, especially the damage to rice buds is more serious. Rubbing will not only damage the seeds, but long-term wear will also cause the inner surface of the seed protection board to form grooves on the track where the seeds pass, which reduces the seed protection effect and service life of the seed...

AI Technical Summary

Problems solved by technology

While the fixed seed protection board realizes the above functions, it will inevitably rub the seeds passing through the seed protection area, causing damage to the seeds, especially for rice buds.

Rubbing will not only damage the seeds, but long-term wear will also cause the inner surface of the seed protection board to form grooves on the track where the seeds pass, which reduces the seed protection effect and service life of the seed protection board. Between the seed plate and the hole wheel, it will have an adverse effect on the normal operation of the seed meter, and even cause damage
