Problems solved by technology

At the same time, due to the large difference in the sowing amount of rapeseed and wheat in agronomic cultivation, the sowing amount per mu of rapeseed is 150-250g, and the sowing rate of wheat is 5.0-20.0kg per mu; the skin of rapeseed is thin and has high oil content, which is easily damaged, which significantly affects the sowing quality
The existing air-flow seed metering device is suitable for large-sized seeds such as wheat, but not suitable for precision sowing of small-sized seeds such as rapeseed. poor uniformity

Abstract

The invention discloses a rape and wheat dual-purpose pneumatic centralized discharging device. The device comprises a fan, a pressure regulation valve, a support frame, a seed supply unit, a seed box, a seed discharging tube, a pressure increasing tube, a distributing unit, a seed delivery tube, a seed delivery elbow, a supply unit, a double-disk opener and a speed changing unit for regulating the rotation speed of the seed supply unit and transmitting power. According to the centralized discharging device, sowing in eight lines can be completed simultaneously, seed feeding, exchanging and discharging are facilitated, a transmission system and the whole device structure are simplified, and the device is convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of crop seeding equipment, in particular to an oil-and-wheat dual-use air-supplied collector. Background technique [0002] Seeding is a key link in agricultural production. "Seven divisions, three divisions" shows the importance of sowing quality. Seeding quality significantly affects the quality of seedling emergence, seedling growth, water and fertilizer utilization, yield and production benefits, etc. The seeder determines the sowing quality Technical support. The seed metering device or the seed metering system is the core working part of the planter. The single-type seed metering adopts the "one machine and one line" layout, which mainly has the problems of complex machine and transmission system, high cost and cumbersome seed loading and unloading; Multi-row seeding adopts the "one device, multiple rows" seeding method, which mainly uses a set of seeding components, a seed box and a unified seeding system...
