Abstract

The dual-hole air-suction universal energy-saving seed metering device for soybeans and corn belongs to the technical field of agricultural machinery. The edge of the seed metering device in the present invention is provided with a double-suction hole seed-taking groove, and a groove is arranged in the seed-taking groove for soybean harvesting. The double suction hole is connected with the air suction channel, and the air suction channel is connected with the double suction hole and the negative pressure chamber. The negative pressure chamber is formed by the cooperation of the disc body and the gas cover. There is an isosceles cone ring on the body; the air cover fits on the bearing, and the ring fastens the air cover on the bearing; The isosceles cone ring clearance fit of the disc body and the gas cover is ensured. The invention realizes the universal seeding of soybeans and corns, and it is known from aerodynamics that the clearance fit between the waist surface of the isosceles cone ring will form a continuous curved path, which will have a throttling effect on the air flow, thereby reducing the air-suction discharge rate. The air pressure loss of the seeder.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a double-hole air suction universal energy-saving seed metering device for soybeans and corn. Background technique [0002] Most of the current seeding trays have single air suction holes, which have poor adsorption effect on irregularly shaped corn. For the single-hole air-suction general-purpose pan for soybeans and corn, the design difficulty is increased. In addition, for the existing air suction method, the negative pressure chamber is mostly used to directly cooperate with the air suction hole on the disk body. Necessary air pressure loss. And because the 3D printing technology for the materials required for the seed tray is mature, it is possible to design parts with more complex structures. Therefore, it is necessary to design a seed meter that can better absorb irregular seeds and reduce air pressure loss. Contents of the invention [000...
