Longitudinal axial flow threshing device with side window

Abstract

The invention discloses a longitudinal axial flow threshing device with a side window, which comprises a frame, a threshing assembly, a window body assembly and a vibrating screen, wherein the threshing assembly is provided with a front half shaft, a spiral conical feeder, a threshing roller, a concave screen and a top cover; the front end of the spiral conical feeder is connected with the front half shaft through a flange and the rear end of the spiral conical feeder is coaxially and rigidly connected with one end of the threshing roller; the other end of the threshing roller is fixedly connected with a rear half shaft; the window body assembly consists of a window, a protective cover, a spring lock, a locking rod and an air spring supporting rod; the window is arranged above one side of the frame; the upper end of the protective cover is hinged with the top of the frame; the spring lock is arranged on the lower part of the protective cover; the locking rod matched with the spring lock is fixed on the frame; and one end of the air spring supporting rod is hinged with the frame and the other end of the air spring supporting rod is hinged with the protective cover. The technical states and working conditions of the threshing roller, the concave screen and the vibrating screen can be clearly seen through the window.

Description

Technical field: [0001] The invention relates to the technical field of harvesters, in particular to a threshing device of a grain longitudinal axial flow combine harvester with side windows. Background technique: [0002] Rice and wheat are the crops with the largest planting area in the world, and the mechanized harvesting of rice and wheat is an important guarantee to ensure a high yield of rice. At present, grain harvesting mainly uses the horizontal axial flow combine harvester which is mature in technology and widely used. However, the threshing drum of the horizontal axial flow combine On the small harvester, the threshing and separation performance is better when harvesting with high stubble, and the feeding amount is large when harvesting with low stubble, the performance of threshing and separation is reduced, and the efficiency is reduced; when the crop is wet, it is easy to block the drum. With the formation of industrialized production scale and moderate-scale ...

AI Technical Summary

Problems solved by technology

But at present, the threshing assembly and the separation and cleaning assembly of the longitudinal axial flow combine harvester are evenly enclosed in the box formed by the frame guard plate, and there is no corresponding function of observation, debris cleaning, and maintenance on the frame guard plate. The window makes it difficult to observe the technical status and working conditions of the machine's threshing assembly, separation and cleaning assembly and other components. Once the grain stalk is blocked when it is wet, the machine cover must be opened to clean it. When the parts are damaged, it is very inconvenient to repair and replace them. User maintenance brings great inconvenience
