Problems solved by technology
At present, soybean double-row, triple-row and corn single-row seed metering devices cannot be used universally
If two seeders are used to sow double strips on the ridge, or to achieve single, double, or triple seeding by replacing the seeders, it will not only increase the manufacturing cost, but also bring difficulty in replacement.

A corn and soybean air suction type universal seed metering device belongs to an agricultural machine; a chamber formed by a casing and a casing cover plate is separately provided with a double-row soybean seed discharge plate or a three-row soybean seed discharge plate or a corn seed discharge plate which can be switched, a seed discharge plate sealing plate is mounted on the end part of one sideend of the double-row soybean seed discharge plate or the three-row soybean seed discharge plate or the corn seed discharge plate, a negative pressure air chamber is formed in the chamber of the double-row soybean seed discharge plate or the three-row soybean seed discharge plate or the corn seed discharge plate, the negative pressure air chamber is connected with an air suction port, air suctionholes on the double-row soybean seed discharge plate or the three-row soybean seed discharge plate or the corn seed discharge plate communicate the negative pressure air chamber and a seed chamber inthe casing; the corn and soybean air suction type universal seed metering device is reasonable and simple in structure, high in degree of generalization, simple and quick in operation and replacementand high in use efficiency.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a universal seed metering device for double and triple row sowing of soybeans and single row sowing of corn. Background technique [0002] In Heilongjiang Province, two or three rows of soybeans and a single row of 65-70 cm for corn are commonly used in planting agronomy. Sowing of regular granular seeds such as soybeans mostly adopts edge-type hole-type seed meters or socket-type seed-meterers, while corn uses spoon wheels, finger clips, air-suction flat porous discs, etc. device. At present, soybean double-row, triple-row and corn single-row seed metering devices cannot be used universally. If two seeders are used to sow double strips on the ridge, or to achieve single, double, and triple seeding by replacing the seeders, it will increase the manufacturing cost and cause difficulty in replacement. Contents of the invention [0003] The purpose of the present invention is to s...
