Cleaning blower for combined grain harvester

Abstract

The invention relates to a cleaning blower for a combined grain harvester. The cleaning blower for the combined grain harvester comprises a hydraulic motor, an air inlet, an upper air outlet, a volute and a lower air outlet; the lower air outlet is provided with a lower air outlet division plate I and a lower air outlet division plate II; the air inlet is equipped with an air inflow adjusting mechanism; a first angle adjusting mechanism is installed on the lower air outlet division plate I, and a second angle adjusting mechanism is installed on the lower air outlet division plate II; the hydraulic motor, the air inflow adjusting mechanism, the first angle adjusting mechanism and the second angle adjusting mechanism are connected with a control processor. After using the cleaning blower provided by the invention, the production efficiency and the working time of the complete machine without fault of the combined grain harvester are improved obviously.

Description

technical field [0001] The invention belongs to the design field of a grain combine harvester, and in particular relates to a cleaning fan for a grain combine harvester. Background technique [0002] The cleaning device is the "digestive system" of the combine harvester, and it is the core working part that affects the operation quality, efficiency and adaptability of the whole machine. Most of the rice combine harvesters with the largest stock in my country's market use traditional wind screen cleaning devices. (Including grains, short stalks, glumes and a small amount of light debris, etc.) The floating characteristics are different, and the double-layer vibrating woven screen or fish scale sieve is used to complete the separation and cleaning of grains, stems, and debris. Due to the significant differences in the operating objects of the combine harvester, the ever-changing operating conditions, and the extremely complex operating environment, all of which have significan...

AI Technical Summary

Problems solved by technology

Compared with the advanced combine harvesters of European and American multinational companies, most of my country's grain combine harvesters are only equipped with a small number of alarm devices such as blockage and full grain tanks, and generally lack intelligent monitoring such as monitoring of working parameters and performance, electric / automatic adjustment of working parameters, etc. The device makes the operation performance of the machine unstable, and the operation efficiency depends on the proficiency of the machine operator, and the operation intensity is high, and the blockage failure occurs frequently. Operational requirements for chemical production and rice-oil (wheat) rotation areas such as rush harvesting and rush planting
