Reciprocation-swing type seed breeding and discharging device of discharge plate

Abstract

The invention discloses a reciprocation-swing type seed breeding and discharging device of a discharge plate, and belongs to agricultural machines. A driving shaft and a supporting shaft are assembled in parallel on a seed discharging device shell assembly provided with a seed filling chamber and a seed discharging chamber. A chain wheel and a crank are fixedly installed at the two ends of the driving shaft, a pressing limiting sleeve can rotate in the circumferential direction, and the supporting shaft can be sleeved with the pressing limiting sleeve in an axial moving mode. A swing disc is fixedly installed on the supporting shaft and sleeved with a seed discharging disc, the seed discharging disc is pressed on the swing disc under cooperation among a plane bearing, a pressure spring and the pressing limiting sleeve, spherical protruding pillars on the side face of the seed discharging disc are in insertion cooperation with spherical pits in the side face of the swing disc, and seed filling hole sets of four specifications are evenly formed at 90-degree intervals in the seed discharging disc. Circular-arc-shaped through holes and pin holes are formed in the swing disc and the seed discharging disc respectively, and a seed discharging amount regulation plate and a seed guiding pipe are assembled on the lower side portion of the seed discharging device shell assembly. The device is novel and reasonable in structure, wide in application range, high in utilization rate of operation and easy and convenient to adjust.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical seed metering device. Background technique [0002] The currently used seed-filling hole seeding discs are uniformly arranged with filling-type holes of a certain size on the peripheral edge of the seeding disc. Rotate to complete the filling and sorting operations. In the above technology, one kind of seed tray can only adapt to the sowing requirements of one variety or the same specification of seeds. Seed grains of different varieties and sizes need to be completed by different seed-filling hole seed trays. The seed metering device not only needs to be equipped with Seed trays with multiple specifications and sizes increase the manufacturing cost and poor adaptability, and the operation of replacing the seed trays is cumbersome, which reduces the operating efficiency of the machine tool. Especially for plot breeding and sowing operations, seed varieties and seed sp...

Problems solved by technology

In the above technology, one kind of seed tray can only adapt to the sowing requirements of one variety or the same specification of seeds. Seed grains of different varieties and sizes need to be completed by different seed-filling hole seed trays. The seed metering device not only needs to be equipped with Seed trays of various specifications and sizes increase the manufacturing cost and poor adaptability, and the operation of replacing the seed trays is cumbersome, which reduces the operating efficiency of the machine tool

Especially for plot breeding and sowing operations, seed varieties and seed specifications are often changed and replaced. It is difficult for the above-mentioned existing seed-filling hole metering devices to meet and adapt to the needs of breeding operations.
