Pneumatic conveying type multiway discharging device used for discharging seeds or fertilizer

Abstract

The invention discloses a pneumatic conveying type multiway discharging device used for discharging seeds or fertilizer. The pneumatic conveying type multiway discharging device comprises a case, a discharging assembly, a driving unit, a blower and an unloading pipe; an unloading area formed by a material cabin, an air cabin and a plurality of unloading channels are arranged in the case; discharging assemblies which are as many as the unloading channels are mounted in the case; the discharging assemblies are driven by the driving unit to rotate; the air cabin is in a shape of a long strip, andthe blower is mounted at one side end of the air cabin and can blow airflow into the air cabin; an air outlet is formed in the side edge of the air cabin; and the unloading pipe is used for bearing an agricultural material falling from the unloading channel and airflow overflowing from the air outlet. By means of the case provided with the material cabin, the air cabin and the unloading area, thedischarging assemblies and the blower, multiway discharging and pneumatic assisted unloading can be realized, the overall structure is simple and compact, unified charging and concentrated discharging can be realized, and the falling uniformity is good.

Description

technical field [0001] The invention relates to the technical field of agricultural tillage and sowing machinery, in particular to a pneumatic conveying multi-way discharger for seed or fertilizer discharge. Background technique [0002] Agricultural machinery is the foundation of modern agriculture. Agricultural machinery can realize automatic plowing and sowing of agricultural materials such as seeds and chemical fertilizers, greatly improving the efficiency of plowing and sowing. In order to achieve the uniformity of seeding or fertilization in the process of automatic tillage and sowing, a discharger is needed. The discharge components in the discharger can make the flow of agricultural materials be discharged stably and continuously for sowing, so as to meet the needs of uniform spreading of agricultural materials . [0003] Existing agricultural machinery generally adopts a single-unit seed metering device. As many rows as the plowing and sowing machinery can sow at a...

AI Technical Summary

Problems solved by technology

[0003] Existing agricultural machinery generally adopts a single-unit seed metering device. As many rows as the plowing and sowing machinery can sow at a time, as many dischargers (one device per row) need to be installed. The single-piece discharger not only takes up a lot of space, but also requires The hopper of each discharger is charged separately, and it is inconvenient to adjust the discharge volume. Most of them rely on adjusting the effective length of the discharge trough to adjust the discharge volume, which requires high assembly accuracy for each seed discharger.
