A top-discharging seed meter with clamping

Abstract

The present invention is a type of seed metering device with clamping top and unloading, which is suitable for the field of agricultural machinery for precise sowing of multi-species seeds. Including electric motor, seed metering pipe, seed metering pipe bracket, seed metering pipe bracket fixing frame, seed warehouse, seed warehouse fixing bracket, frame, nut, driven shaft, pin, clamping hole, lower support plate, driving shaft, row species belt. It is characterized in that: the motor is fixed on the frame, the driving shaft is connected to the motor, the driven shaft is fixed on the frame, and the seed metering belt is fixed by the protrusion on the driven shaft and the driving shaft. and rotation, the seed metering pipe and the seed metering belt are gap-fitted, the seed metering pipe bracket, the lower support plate and the seed metering pipe bracket fixing frame are connected together by pins, and are installed on the rack, the seed metering pipe bracket The fixed frame and the seed tube support can move along the frame, and the seed bin is installed on the frame. The invention can realize the high-speed continuous precision seeding operation, improve the operation efficiency, reduce the labor cost, and greatly improve the seeding quality.

Description

technical field [0001] The invention relates to a clamping and top-discharging seed metering device, which is especially suitable for the field of agricultural machinery for precision sowing of multi-variety seeds. Background technique [0002] At present, commonly used seed meters at home and abroad can be divided into precision seed metering and non-precision seed metering according to whether they can form equidistant and uniform seed flow and accurately control the number of seed metering. Precision seed metering can be divided into mechanical and pneumatic seed metering devices, of which pneumatic seed metering devices include three types: air pressure type, air suction type and air blowing type. Its various seed meters have the following characteristics: [0003] The mechanical disc seed metering device is a kind of widely used seed metering device, which can be divided into three types: horizontal, inclined and vertical according to the position of the rotating plane...

AI Technical Summary

Problems solved by technology

It has the advantages of good seed filling performance, easy adjustment of plant spacing and less strict requirements on seed shape, but its production cost is relatively high and its structure is relatively complicated

[0006] The seed metering device proposed above has the following disadvantages: it is easy to cause damage such as fracturing and wear to the seeds during sowing, reducing the emergence rate; the mechanical structure is complex and easy to wear; the sowing accuracy is not easy to guarantee, resulting in multiple or lack of seeds. Affects grain production; high power requirements and high production costs
