Summary of the invention

(the problem to be solved in the present invention)

(1) problem corresponding with background technique (1) is as follows.

In above-mentioned existing structure, for example, processed material is blocked in the inside of sheller unit when the progress with harvesting Whens delay etc., need that the top plate portion of sheller unit is switched to rising posture manually after grain box to be switched to rising posture, Keep threshing chamber open to be overhauled.The top plate portion of sheller unit is made of thicker metal plate, thus will not be because with de- The threshing of grain cylinder is handled and the contact etc. with processed material causes to wear and breakage earlier.As a result, the weight of top plate portion is larger, Weight load by the open operation of the top plate portion of manual operation progress is larger.

In addition, in the prior art, in order to mitigate the weight load of top plate portion, such as with gas damper, thus into The auxiliary of row lifting operations, however, for large-scale sheller unit, only the booster action with 1 gas damper not enough, The burden on labour is caused to operator.It is also contemplated that using multiple gas dampers, but number of components increase leads to cost Rise.

Herein, it is desirable to cost increase will not be caused, and can easily be done the upkeep operation of sheller unit.

(2) problem corresponding with background technique (2) is as follows.

In above-mentioned existing structure, make multiple thread-like members in sieve line extended in cantilever manner by having, from threshing chamber The processed material leaked down carries out difference in specific gravity sorting by sieve line, and then carries out making grain and with branch while rearward transferring grass cuttings The secondary object such as the grain of stalk is leaked to the sorting process of lower section.Mitigate the processing load of chaffer as a result, and prevents on chaffer The case where accumulation includes the processed material of a large amount of grain and side's discharge is immediately rearward so as to cause a large amount of grain losses.

However, carrying out threshing to crop by the thrashing cylinder being driven in rotation in threshing chamber in above-mentioned existing structure Processing, bearing net are provided only on the half-cycle portions of the lower side of the peripheral part of thrashing cylinder.According to above structure, in the position of bearing net In the direction of rotation upstream side of thrashing cylinder, the processed material transferred is removed by thrashing cylinder and is leaked together along upper half side half-cycle portions Under, therefore, side is swum in a rotational direction, compared with the downstream side part of direction of rotation, there are a large amount of processed materials to leak down.

As a result, the processed material leaked down from threshing chamber is leaked down with the state for the side being biased against on oscillatory sorting device, One end side in width direction corresponding with the direction of rotation upstream side of thrashing cylinder, there are a large amount of processed materials to cause It is thicker, and other side position is that amount is less and relatively thin, to form unbalanced state.

Also, sieve line and chaffer makes the secondary object such as grain and the grain with branch stalk while rearward transferring processed material Leakage is to lower section, in the state of forming uneven thickness along width direction as described above, even if being provided to the processing of sheller unit Object amount generally suitably handle object amount, the thicker position of processed material also have more processed material be deposited on chaffer from And foreign side is discharged, thus likely result in a large amount of grain discharges and cause damages.

However, can be arranged in the upper side of grain pan for making processed material in the direction of the width if not using sieve line Equally distributed screed, but grain pan can rearward transfer whole processed materials, cause the processing load of chaffer larger.

Herein, it is desirable to the processing load of chaffer can not only be mitigated using sieve line, and oscillatory sorting device can be made On processing object amount equalization, loss caused by avoiding grain from being largely discharged.

(3) problem corresponding with background technique (3) is as follows.

In the above prior art, when dismounting oscillatory sorting device, need to remove or install lateral connection shaft, the installation Operation and remove the more difficult progress of operation.That is, needing on one side when taking out oscillatory sorting device with hand bearing oscillatory sorting device Weight, on one side to connection shaft is laterally extracted out, to cause biggish labour to bear to operator.Also, when installation swings sorting When device, similarly, the weight of the rear portion side with hand bearing oscillatory sorting device on one side is needed, makes wobble drive portion and pendulum on one side Swing arm is directed at position, to cause biggish labour to bear to operator.

Then, to solve the above-mentioned problems, it is contemplated that following structure-improved.

In the bond sites of connection oscillatory sorting device and wobble drive portion, in the pivot branch of the eccentric axial portion to rotation It holds bond sites and clips the state that eccentric axial portion is dispersed in two sides, there is the first linking part for being integrally attached at oscillatory sorting device Part and to clip the second connecting member that the state of eccentric axial portion is removably attached at the first connecting member.

In the structure-improved, in the state of releasing connection, the first connecting member can be temporarily set to be supported on eccentric shaft Portion carries out labour's burden when dismounting operation so as to mitigate to make eccentric axial portion weight to oscillatory sorting device. However, in this configuration, there are still following problems.

First connecting member and the second connecting member clip eccentric axial portion and are dispersed in two sides, due to clipping eccentric axial portion dispersion It is made respectively in the first connecting member of two sides and the second connecting member, therefore, the error etc. that group is loaded onto when because of both connections can It can cause at the position for clipping eccentric axial portion connection, a part in a circumferential direction forms minimum step, as rotation is transported Movable property gives birth to gap.As a result, thering is the position in gap to damage earlier with lasting use, so as to cause durability decline.

Herein, it is desirable to provide one kind can not only mitigate labour's burden when the dismounting operation for carrying out oscillatory sorting device, And it can be improved the combine harvester of durability.
