Abstract

The invention relates to a seed distributor of a pneumatic conveying type wheat seeding machine, and belongs to the technical field of seeding devices of agricultural machinery. The seed distributor of the pneumatic conveying type wheat seeding machine comprises a seed distributor body, a flow distribution cover, seed guide pipe connecting ports, a seed guide wall, a gas and solid mixing wall, anda seed conveying pipe connecting port, wherein the flow distribution cover is arranged at the center position of the upper end of the seed distributor body; the upper end surface of the seed distributor body is provided with the multiple seed guide pipe connecting ports, the upper end surface of the seed distributor body is connected with one end of a first side wall, the other wall of the firstside wall is connected with one end of an inclined side wall, and the inclined side wall is used as the seed guide wall; and the other end of the inclined side wall is connected with the gas and solidmixing wall, the other end of the gas and solid mixing wall is connected with the side wall of the seed conveying pipe connecting port, and the inner surface of the gas and solid mixing wall is uniformly distributed with annular bulges. The seed distributor involved in the invention has the beneficial effects that the uniformity in seed discharging is good; the breaking rate of seeds is low; thecost is low; and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery sowing devices, and in particular relates to a seed divider of a pneumatically conveyed wheat seeder. Background technique [0002] Wheat seeder is a very important machine in grain planting. There are few studies on pneumatic conveying wheat seeder in my country. High-speed operation of pneumatic conveying wheat seeder will affect the quality of sowing, high production cost, high seed breakage rate during high-speed operation, Problems such as poor consistency of the displacement of each row will affect the uniformity of seeding when the air flow is disordered. [0003] The seed meter is the core working part of the dry hole direct seeding machine, and the performance of the seeder is directly related to the quality of the seed meter. With the continuous expansion of the large-scale wheat planting area, it is very urgent to develop a wheat seeder that can achieve high-speed and wid...
