Vibration disturbance seed filling and air-blowing attitude-control seed metering combined type seed metering device

Abstract

The invention discloses a vibration disturbance seed filling and air-blowing attitude-control seed metering combined type seed metering device, and belongs to agricultural machinery. The seed metering device comprises a vibration disturbance seed filling and metering system and an air-blowing attitude-control seed metering system, wherein the vibration disturbance seed filling and metering system consists of an annular groove-shaped seed box, an annular vibration disturbance plate, an annular rubber vibration absorption pad, a pressure spring, a rotating cylinder, a hollow transmission shaft, an upper seed metering pipe, a lower seed metering pipe, a supporting plate, a hollow motor, a fixed vertical shaft, a cam, a vibration exciter, a spring seat plate, a seed conveying plate, a roller, a transmission shaft and a seed box fixed supporting seat, and the air-blowing attitude-control seed metering system is composed of an air blower, a fixator frame, a connecting sleeve, an air pipe, a pipe bundle frame and a pipe seat. While the vibration disturbance seed filling and metering system adjusts the seed filling attitude, the seed fluidity is improved, the seed filling efficiency is high, the air-blowing attitude-control seed metering system effectively and reliably regulates and controls the attitude of seeds discharged from the lower seed metering pipe, and the germination parts of the seeds are ensured to be upward; and the seed metering device has the characteristics of unique, scientific and reasonable structure, good seed filling and metering operation quality, high efficiency and reliability in use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a combined seed metering device for seed filling with vibration disturbance and air blowing to control seed posture. Background technique [0002] When the existing hole and socket type seed metering device and the finger clip type seed metering device are carrying out the seed filling operation, the seeds are all filled into the above-mentioned seed metering device from the flow capacity generated by the dead weight in the seed box. Due to the shape of the seeds and the posture in the seed box, and the extrusion between the seeds due to gravity, the fluidity of the seeds is poor, and it is very easy for the seeds to be leaked, resulting in cavities and reducing the quality of sowing. In addition, when the seeds are discharged from the seed metering device through the seed guide pipe, the postures of the seeds are chaotic, and the posture of the seeds being sown into the soil of the...

Problems solved by technology

Due to the shape of the seeds and the posture in the seed box, coupled with the extrusion between the seeds due to gravity, the fluidity of the seeds is poor, and the phenomenon of seed leakage is easy to occur, resulting in cavities and reducing the quality of sowing.

In addition, when the seeds are discharged from the seed metering device through the seed guide pipe, the postures of the seeds are chaotic, and the posture of the seeds being sown into the soil of the seedbed cannot be controlled, and it is difficult for the seeds to germinate, especially in recent years. With the improvement of scientific and technological level and agronomic requirements, how to reliably and effectively adjust and control the filling posture and seeding posture of the seeds during the filling and rowing operations has become a technical problem that agricultural machinery research and development technicians should solve.
