Wind Structure Dust Removal System of Wheat Combine Harvester

Abstract

The invention discloses a wind-force structured dust removal system for a wheat combine harvester, which comprises a reel cover, an elbow pipe for transporting dust particles, a centrifugal fan attached to the wheat combine harvester, and a gravity separation and dust removal device for dust and wheat straw; The reel cover is installed at the header of the wheat combine harvester and covers the upper part of the reel; the gravity separation and dedusting device for dusty wheat straw includes an ascending pipe connected in sequence to the outlet end of the centrifugal fan and extending along the upward direction, a horizontal Pipe I, vertical pipe I, straight pipe II, straight pipe III, straight pipe IV and straight pipe V, the angle between straight pipe II and vertical pipe I counterclockwise is 135°, straight pipe II, straight pipe III, straight pipe The angles between the four adjacent pipes of pipe IV and straight pipe V are all 90°. The invention designs a reasonable and effective dust-removing structure for the dust-prone parts in the operation process of the wheat combine harvester. The structure design is reasonable, the cost is low, and the dust pollution caused by the operation of the wheat combine harvester is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural harvesting machinery, and relates to a wind-driven structural dust removal system for a wheat combine harvester, in particular to a system for solving the problem of dust pollution during operation of the wheat combine harvester by optimizing the overall structure of the wheat combine harvester. Background technique [0002] Since the reform and opening up, the rapid development of my country's heavy industry, light industry, agriculture and handicraft industry has made my country's economic growth rate increase year by year, but it has also brought some negative problems to our country, especially the problem of environmental pollution. my country's ecological civilization construction has been paid more and more attention by relevant departments and the general public. People are more and more eager not only to be satisfied materially and economically, but also to live in a pollution-free en...
