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

However, the receiving network is
When the grain leaks, it receives a large force radially outward from the processed material such as the grain, so as described above, the lower case side receiving net and the upper case side extending receiving net In the configuration in which the adjacent ends in the circumferential direction are merely capable of being engaged and connected, the strength of the connection structure between the receiving net and the extended receiving net is weak, and there is a problem in terms of durability. On the other hand, if the connection structure is strengthened, the frame around the receiving net or the like must be made firm, which causes a problem that the structure becomes complicated and the production cost increases.

[0004] The present invention has been made in view of such a point, and it is an object of the present invention to increase the amount of kernels leaking from a receiving net while preventing the receiving net from receiving a treated material from the radial direction. It is an object of the present invention to provide a threshing apparatus capable of firmly supporting an extension receiving net against a force on one side, having a simple structure, and reducing manufacturing costs.

[0005]

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

[0006]

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

[0007] The support member receives a radially outward force from the workpiece and is supported and supported by the support member in the radial direction. A plurality of the support members are arranged along the axis of the handle cylinder, and each support member locks the other end to the support shaft with one end attached to the back of the extension receiving net. Therefore, the extended receiving net can be strongly supported. Moreover, since only a plurality of the support members are provided as a support structure for the extension receiving net, the structure can be simplified and the production cost can be reduced.

[0008]

As described above, while it is possible to increase the amount of grains leaking from the receiving net, it is possible to firmly support the extended receiving net, to have excellent durability, to reduce the production cost, and to reduce the cost. Excellent threshing equipment could be provided.
