Abstract
The utility model provides a thresher for agricultural crops, which is characterized in that the thresher adopts a rolling type and is composed of a roller and a press roller. The roller is axially parallel to the press roller, and the main power of threshing is from the self-rotation torsion of the roller. Threshing process is mainly finished by the function of rolling. Thus, the breaking of seed removing straw and energy consumption are effectively lowered.
Description
The utility model relates to a kind of improved crops sheller unit, particularly a kind of device that adapts to the legume crop threshing.
The sheller unit that adopts on the existing various thresher almost is drum-type entirely.Its separating mechanism mainly is made up of cylinder and notch board.Threshing course is to finish by the interaction between cylinder, crop, the notch board.The main weakness of threshing legume crop (relying on strike, kneading action) is that the straw standing grain is broken serious.So threshing energy consumption height, the seed damage loss is big, the separating cleaning operational difficulties after the threshing.
The purpose of this utility model is that a kind of improved sheller unit will be provided.It greatly reduces the straw standing grain fragmentation of legume crop threshing.
The utility model is to realize like this.Owing to press stone roller threshing course (as stone roll extrusion field) very little to the effect of tearing of crop, this sheller unit adopts roller type.This presses stone roller mechanism mainly to be made up of roller and nip drum.Roller and nip drum axially are parallel to each other, and press the stone roller gap to float with the variation of crop feed quantity.The threshing active force from roller from torque.Flailing action power--the size of pressing stone roller power is by nip drum gravity and given with joint efforts (the pressure values scope is preferably rolled pressure to ground a little more than the stone of having a meeting, an audience, etc. well under one's control) of executing elastic force outward.The nip drum that this pressure is ground mechanism can rotate or rotation with the motion of being taken off crop, and its rotary resistance or rotational velocity are preferably adjustable, in order to adjust the assisted action of rubbing of threshing course, improves the real scope of answering of threshing.According to the designing requirement difference of threshing condition and scope, this sheller unit can be provided with some grades and press and grind mechanisms' (comprising one-level).
Below reaching accompanying drawing in conjunction with the embodiments is further described realization of the present utility model.
Accompanying drawing is a kind of three grades and presses the side-looking structural representation of the present utility model of grinding mechanism.
With reference to accompanying drawing, this sheller unit is provided with three grades and presses stone roller mechanism.Main working parts by roller (1) nip drum (2), (3), (4), roll (5) conveyer belt (6) and conduction wheel (8) is formed.Along pressure (Pn) direction the nip drum axis rail is set.Pressure (Pn) is nip drum deadweight, guide rail support reaction and outer executing making a concerted effort of elastic force.During the work of this sheller unit, roller (1) is done uniform rotation, is taken off crop (7) to feed separating mechanism equably by conveyer belt (6) nip drum (2), (3), (the 4) (P that is stressed respectively
1), (P
2), (P
3) and taken off the force action of the wiping power of crop (7), rotate, and along pressure (P
1), (P
2), (P
3) direction floats, and carries out threshing work, implement the pressure of crop (7) is ground flailing action.
Claims (4)
1, a kind of to press the crops sheller unit that grinds flailing action, it is characterized in that the separating mechanism of this device mainly is made up of roller and nip drum.
2, device according to claim 1 is characterized in that roller and nip drum axially are parallel to each other, and nip drum rotates under external force and floats by self track.
3,, it is characterized in that the driving torque (or rotating speed) of nip drum is adjustable according to claim 1,2 described devices.
4, device according to claim 1 is characterized in that the roller of separating mechanism and the drive of intake mechanism conveyer belt are same workpiece.
