Abstract
Total banding drive rotary mechanism of threshing cylinder notch board for thresher belongs to agricultural machine, admittedly, adorn annular zone circle on the tip of threshing cylinder notch board assembly, circle in the gridle, join in marriage along the circumferencial direction equipartition and adorn a plurality of round pins axle, install antifriction bearing respectively on the same side end of a plurality of round pin axles, lateral part department at annular zone circle, it is radial with annular zone circle, circumference and axial positioning, and the fixed rolling bearing ring seat that sets up with the axle center, antifriction bearing is located the annular roll slide groove of rolling bearing ring seat, the driving pulley configuration is in annular zone circle lateral part department, the drive belt suit circles at driving pulley and gridle, this mechanism has realized the rotatory operation of threshing cylinder notch board assembly, and novel structure, simple, equitable uses reliably, and the work quality that threshes is good, and production efficiency is high.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to the sheller unit on threebing machinery.
Background technology
Sheller unit on threebing machinery assembles formation primarily of two parts of threshing cylinder axle assembly and threshing concave plate assembly.During operation, carry out threshing operations by the threshing cylinder axle assembly rotated, then under fixed threshing concave plate assembly coordinates, the seed taken off is separated threshing detached job by the gap of threshing concave plate assembly in release unit.On the thresher in latter stage in nineteen sixties to century; its threshing concave plate assembly adopts overall cornerite to be less than the arc surfaced structure of 180 °; entirety is packed in below threshing cylinder axle assembly; during operation; because the seed taken off can only be discharged from the arc surfaced threshing concave plate assembly being positioned at cornerite below threshing cylinder axle assembly and being less than 180 °; operating efficiency is low, seed damage is high, the technical problem of seed cleannes difference is very outstanding; if during de-corn operation; the percentage of damage of corncob is also very high, brings difficulty to the exploitation again of corncob.For the problems referred to above that the threshing concave plate assembly solving fixed arc surfaced structure exists, a kind of entirety is that the threshing cylinder notch board assembly of 360 ° of structures starts to apply on threebing machinery in recent years.During assembling, rotating threshing cylinder axle assembly is configured in fixed 360 ° of threshing cylinder notch board assembly centres, cylinder shaft assembly integral contains by threshing cylinder notch board assembly, seed when achieving threshing operations after threshing can carry out seed detached job within the scope of 360 ° of fixed threshing cylinder notch board assembly, compared with conventional art, threshing operations efficiency and operation quality are improved.But along with the raising of agricultural production work capacity; more and more higher to the requirement of thresher threshing operations production efficiency and production capacity; fixed threshing cylinder notch board assembly can not meet production operation requirement, and the threebing machinery researching and developing a kind of new construction is to meet and to adapt to need of production extremely urgent.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing; research and develop a kind of thresher threshing cylinder notch board assembly band and drive rotating mechanism; by the threshing cylinder notch board assembly be configured on threebing machinery being realized the technical scheme of rotary motion, reach the object of threshing operations efficiency, seed detached job efficiency and the grain cleaning rate increasing substantially threebing machinery.
The object of the invention is achieved in that thresher threshing cylinder notch board assembly band drives rotating mechanism to comprise threshing cylinder notch board assembly, the end of described threshing cylinder notch board assembly fixedly mounts annular zone circle, on described annular zone circle, along the circumferential direction uniform equipped multiple bearing pin, rolling bearing is installed respectively in the end, the same side of described multiple bearing pin, at the sidepiece place of described annular zone circle, radial with annular zone circle, circumference and axial location, and concentric be fixedly installed rolling bearing ring seat, described rolling bearing is positioned at the annular rolling slideway groove of rolling bearing ring seat, coordinate in contact, what driving pulley and annular zone circle were positioned at same transmission plane is configured in annular zone circle sidepiece place, driving-belt is sleeved on driving pulley and annular zone circle.
The invention maintains static the technical problem of technical scheme existence for threshing cylinder notch board assembly on arc surfaced threshing concave plate assembly on traditional thresher and existing thresher on thresher; adopt the equipped threshing cylinder notch board assembly of rolling bearing ring seat supporting; coordinate rotary power drives structure; the unitary rotation of threshing cylinder notch board assembly when achieving threshing operations; fundamentally change conventional solution; create good technique effect, there is novel structure, simply, rationally, use the feature reliable, threshing operations quality is good, production efficiency is high.

Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.A kind of thresher threshing cylinder notch board assembly band drives rotating mechanism to comprise threshing cylinder notch board assembly 1, the end of described threshing cylinder notch board assembly 1 fixedly mounts annular zone circle 7, on described annular zone circle 7, along the circumferential direction uniform equipped multiple bearing pin 3, the end, the same side of described multiple bearing pin 3 installs rolling bearing 2 respectively, at the sidepiece place of described annular zone circle 7, radial with annular zone circle 7, circumference and axial location, and concentric be fixedly installed rolling bearing ring seat 4, described rolling bearing 2 is positioned at the annular rolling slideway groove of rolling bearing ring seat 4, coordinate in contact, what driving pulley 5 and annular zone circle 7 were positioned at same transmission plane is configured in annular zone circle 7 sidepiece place, driving-belt 6 is sleeved on driving pulley 5 and annular zone circle 7.
During use, rolling bearing ring seat 4 is utilized to be fitted on thresher by the invention entirety, described rolling bearing ring seat 4 maintains static, it is inner that original cylinder shaft assembly integral on thresher is positioned at threshing cylinder notch board assembly 1, during operation, entered in sheller unit by de-material from the end-face central hole of threshing cylinder notch board assembly 1, on thresher, original threshing cylinder axle assembly rotates, meanwhile, the driving pulley 5 of active rotation is by driving-belt 6, annular zone circle 7 is at bearing pin 3, under rolling bearing 2 coordinates with rolling bearing ring seat 4, drive threshing cylinder notch board assembly 1 in rolling bearing ring seat 4 in turning to rightabout rotation with threshing cylinder axle assembly, namely threshing cylinder notch board assembly 1 and threshing cylinder axle assembly are backwards rotation, the rotation of threshing cylinder notch board assembly 1 when realizing operation.According to conditions such as Different Crop kind and crop humidity, selection adjustment can be carried out to the rotating speed of threshing cylinder notch board assembly 1.
In scientific research and testing, compared with the existing thresher maintaining static threshing cylinder notch board assembly structure, ensureing that under the prerequisite that seed integrity degree, seed cleannes and power consumption are constant, threshing efficiency and the separative efficiency of the invention improve more than 30%.To in corn ear threshing, except aforementioned index, the integrity degree of corncob reaches more than 70%, for the comprehensive utilization of corncob provides very good material.The invention technique effect is outstanding and remarkable.
