Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention supports an upper case, on which a handling cylinder is mounted, swingably openable and closable with respect to a lower case around a support shaft substantially parallel to the handling cylinder axis. Relates to a threshing device provided with an arcuate receiving net along the circumferential direction of the handling cylinder.

[0002]

2. Description of the Related Art In this type of thresher, it is desired to increase the leakage area of the net and improve the processing capacity.
In the conventional thresher, since the receiving net is provided only on the lower case side, there is a limit to increase the leakage area of the receiving net. Therefore, as disclosed in Japanese Utility Model Laid-Open No. 4-77739, a structure has been proposed in which an extension net is arranged on an extension line in the circumferential direction of the net on the upper case side to increase the leakage area of the net. Was there. Specifically, this structure is configured such that an extension net is arranged on the extension line so that adjacent ends in the circumferential direction of the lower case side net and the upper case side extended net can be engaged and connected. The support frame for supporting the straw cutting blade is provided along the axial direction at the other end portion of the extension net in the circumferential direction.

[0003]

However, the receiving network is
When the grain leaks, a large force is applied from the processed material such as the grain toward the radially outer side.Therefore, as described above, between the lower case side net and the upper case side extended net. In the structure in which the adjacent ends in the circumferential direction can be engaged and connected to each other, the strength of the connecting structure between the receiving net and the extended receiving net is weak and there is a problem in durability. On the other hand, if the connection structure is to be made strong, there is a problem in that the framework around the receiving net must be made solid and the structure becomes complicated and the manufacturing cost becomes high.

The present invention has been made in view of the above circumstances, and an object thereof is to increase the leakage amount of grain from the net while allowing the net to be received from the treated object in the radial direction. It is an object of the present invention to provide a threshing device capable of firmly supporting the extension net against the force of the other side, having a simple structure, and reducing the manufacturing cost.

[0005]

The threshing device according to the present invention is characterized in that an extension net is provided on an extension line in the circumferential direction of the net on the upper case side, and one end is attached to the back of the extension net. In this state, a plurality of support members are provided along the axial direction of the handling cylinder, the other end of which is locked to the support shaft to receive and support the extension net in the radial direction. .

[0006]

[Function] Since the extension net is provided on the extension line in the circumferential direction of the net on the upper case side, the leakage area of the net is increased,
It is possible to increase the amount of grain leakage from the net.

The support member of the receiving net which receives the force on the radially outer side from the object to be processed is supported and supported in the radial direction. A plurality of the support members are arranged along the axial direction of the handling cylinder. Each support member has one end attached to the back of the extension net and the other end locked to the support shaft. Therefore, the extended receiving net can be firmly supported. Moreover, as the support structure of the extended net, since only a plurality of the support members are provided, the structure can be simplified and the manufacturing cost can be reduced.

[0008]

[Effects of the Invention] Therefore, while the amount of grain leakage from the net can be increased, the extended net can be firmly supported and has excellent durability, and the production cost can be reduced, which is economical. It was possible to provide an excellent threshing device.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a handling barrel 2 that gives a handling action to the grain culms conveyed by the feed chain 1 is arranged inside the handling chamber A, and the lower side of the handling chamber A is along the circumferential direction of the handling barrel 2. Arrangement of an arcuate receiving net 3 and an oscillating sorting device 4 for sieving and sorting the leaked material while oscillatingly transferring it, a sardine picker 5 for sending the sorting air, and the first to collect the grains from the oscillating sorting device 4. A threshing device is configured by providing an object recovery unit 8, a second object recovery unit 9 for recovering the second object from the swing selection device 4, and a dust-exhausting fan 7 for sucking and discharging dust.

The rocking / sorting device 4 has a process of leaking from the handling chamber A into a swinging / sorting case 35 of a hollow frame type which is rockably driven by the slide guide mechanism 31 and the crank rocking mechanism 32. A coarse sorting unit 15 that receives and swings and transfers the rough sorting, and a swinging process of the sorted products leaked from the rough sorting unit 15 while sorting and leaking the grains to the first product collecting unit 8. And a fine sorting section 16 for dropping the second article onto the second article collecting section 9 arranged on the lower side in the transfer direction.

The rough sorting section 15 receives the processed material which has been treated on the upper side of the grain handling direction in the handling room A and which has leaked from the receiving net 3, and sorts the specific gravity by the specific gravity difference.
8, the chaff sheave 19 arranged in a state of being connected to the lower side in the transfer direction of the first Glen pan 18, the second Glen pan 20 that receives the processing object falling from the dust delivery port 33 of the handling chamber A, and the dust delivery port 33 The first straw rack 21 for sending out the scraps of the processed material to the lower side is provided.
