The invention relates to a harvester component, in particular relates to a harvester for axial flow threshing system. A set of axial flow threshing system, including roller, transmission parts, bracket, wherein the conveying member is in above the outside of the drum, the conveying member is composed of stem plate and conveyor chain, the stem plate installed in the drum cover, conveyor chain conveying part is arranged on the support of the two a threshing nail comprises a nail body and a nut, wherein the nail body is a triangle, the triangle in the bottom out of a fit with the nut screw. Compared with the traditional lower threshing system, the invention adopts the method of lifting the height of the conveying part so that the grain passes through the threshing drum and is threshing. In this case, the ear head of the grain falls naturally, and the angle formed with the direction of the threshing nail on the roller is very favorable for threshing the grain, and can avoid excessive breaking of the spike, so that the threshing is more thorough.
【技术实现步骤摘要】
本专利技术涉及一种收割机部件，具体涉及一种收割机上置轴流式脱粒系统。
技术介绍
如图1所示，现有的脱粒系统主要由脱粒滚筒a、脱粒副滚筒b、凹板筛c以及茎杆 输送部件d组成，结构比较复杂。由于该下置式系统的茎杆输送部件d出于脱粒滚筒a偏 下方，谷物是随茎杆输送部件d从脱粒滚筒a的下方通过并被脱粒的。这种结构下由于谷 物的穗头是呈下垂的，与脱粒滚筒a上的脱粒齿运动方向不一致，导致穗头很容易折断。大 部分的杂物倾入了凹板筛并堆起，极易造成堵塞，导致大量的谷粒不能通过凹板筛，反而掉 落在杂物上，并随杂物茎杆一同排出，造成了粮食的浪费。并且飞扬的杂物容易飞入清选系 统，对清选装置造成堵塞，影响清选工作。
技术实现思路
本专利技术的目的是针对上面所述问题，提供一种结构更加简单，且不易堵塞、脱粒更 彻底的收割机脱粒系统。本专利技术是通过以下技术方案予以实现的。一种上置轴流式脱粒系统，包括滚筒、输送部件、支架，其中所述输送部件处于滚 筒外侧的偏上方，所述输送部件由茎杆压板和输送链构成，茎杆压板安装在滚筒盖上，输送 部件的输送链安装在支架上所述二次脱粒钉包括钉身和螺母，所述钉身为三...
