Multi-spiral grass throwing wheel arrangement mechanism for harvester

Abstract

The invention provides a multi-spiral grass throwing wheel arrangement mechanism for a harvester, which comprises a grass throwing wheel transmission shaft and a cylindrical wheel body coaxially sleeved on the grass throwing wheel transmission shaft, a plurality of groups of first grass throwing plate components are mounted on the outer wall of the wheel body, and each group of first grass throwing plate components comprises a plurality of first short grass throwing plate components; the first short grass throwing plate assemblies are arranged on the axial projection plane of the wheel body in an equal-angle circumferential array mode, the first short grass throwing plate assemblies are arranged at intervals in the axial direction of the wheel body, and the first short grass throwing plate assemblies are distributed on the outer wall of the wheel body in a spiral mode. The multi-spiral grass throwing wheel arrangement mechanism is light in weight and is installed at the grass discharging port of the harvester, the grass discharging and throwing capacity is improved, grass throwing is smooth and even, the grass discharging port cannot be blocked, and normal operation of the whole machine is guaranteed; and the structure is simple, the cost is low, and disassembly and assembly are convenient.

Description

Technical field [0001] The present invention relates to a combined harvester technology structure, in particular, involving a multi-spiral measuring meter arrangement for a harvesting machine. Background technique [0002] Existing combined harvesters are generally mounted on the rear of the harvester vents, for discharging crop straw after the threshing; the current market trend is also a combine harvester toward high power, the large feeding direction; With the increasing amount of the big-feeding combined harvester, rice wheat production is also increasing, resulting in more and more crops fed in the harvester, and the amount of row also increases Therefore, the smoothness of the crash is especially important for the normal operation of the whole machine. If the throwing is not smooth, it will cause the threshing cleaning system to block the clogging of the system, which will eventually affect the normal operation of the whole machine; Meet the smooth dramatic rhinar of the bi...

AI Technical Summary

Problems solved by technology

[0002] The weed throwing wheel of the existing combine harvester is generally installed at the rear of the threshing drum of the harvester to discharge the threshed crop straw; the current market trend is that the combine harvester is developing towards high power and large feeding volume; With the increasing number of high-power and large-feeding combined harvesters, the output of rice and wheat has also continued to increase, resulting in more and more crops fed by the harvesters, and the amount of grass discharged will also double. , so the smooth discharge of grass is particularly important for the normal operation of the whole machine. If the grass is not thrown smoothly, it will cause the blockage of the threshing and cleaning system, which will eventually affect the normal operation of the whole machine; and the existing grass throwing wheel rack structure cannot Satisfying the smooth grass discharge of large feed harvester, resulting in grass blocking and affecting the normal operation of the whole machine, so it is urgent to design a grass throwing wheel mechanism with smooth grass throwing and strong grass throwing ability
