Rear-suspension dynamic straw throwing device for longitudinal-axial-flow harvester

Abstract

The invention discloses a rear-suspension dynamic straw throwing device for a longitudinal-axial-flow harvester. The rear-suspension dynamic straw throwing device comprises a straw guide plate, disc throwing structures, a suspension supporting frame, power structures and a retaining structure. The straw guide plate realizes angle adjustment; each disc throwing structure comprises throwing blades,a throwing disc and a disc connection flange; the suspension supporting frame comprises U-shaped suspension plates, two side supporting plates, a motor supporting plate and disc rotating shaft mounting frames; the power structures are in hydraulic transmission or mechanical transmission; the retaining structure comprises a retaining cloth supporting pipe, rubber retaining cloth, a supporting pipeupper connector, a supporting pipe lower connector and angle iron. The disc throwing structures provide kinetic energy for crushed straw, and the straw can be thrown to a width matched with an operating width; the throwing blades comprise front and rear straw gripping plates, gripping and uniform throwing of the crushed straw are facilitated; the retaining structure effectively prevents influencesof crosswind on the throwing width and uniformity in a straw throwing process.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a combine harvester, in particular to a rear-hung straw power throwing device of a longitudinal axial flow harvester. Background technique [0002] In the prior art, the mechanized returning of crop straws is the main way of comprehensive utilization of straws, and the mechanized returning of straws requires the crushed straws to be spread evenly across the entire working width, otherwise the process and quality of subsequent operations will be affected. [0003] In order to improve operating efficiency and reduce secondary operating expenses, when harvesting crops, the wheat and rice combined harvester hangs a straw crushing device at the tail, which is used to crush and throw the straw after drum threshing. [0004] At present, most of the full-feed harvesters use multi-directional deflectors to divert and scatter the crushed straw, but this way of sc...

AI Technical Summary

Problems solved by technology

Therefore, the prior art is badly in need of a detachable rear suspension power throwing device that can be matched with the existing harvester, to solve the existing problem of insufficient power for straw throwing after crushing, and to overcome various defects in the prior art
