Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a threshing device mounted on a combine.

[Conventional technology]

A crimp net woven of metal wire is generally used as a net to control grain leakage from the handling room of the threshing device, but straw chips may be caught and attached to the intersection of the wire, which In order to avoid the above, for example, as shown in Japanese Utility Model Publication No. 54-14964, a receiver net integrally molded with a resin material, or as shown in Japanese Patent Laid-Open No. 57-8712, a crimp net is used. It has been proposed to use a receiving net covered with a resin material.

[Problems to be solved by the invention]

When the receiving net with the above-mentioned configuration is used, the clogging caused by the trapping or sticking of the straw dust at the wire crossing portion, which is seen in the conventional crimp net, does not occur, but the straw dust on the receiving net surface is eliminated. It was not possible to avoid the occurrence of clogging due to the adhesion of the particles or the clog of straw scraps on the wire material forming the mesh.

In particular, when wet threshing is performed in the early morning harvest with morning dew, or after harvesting after rain, the processed material easily adheres on the net and clogging occurs in a short time, Frequent cleaning of the net was necessary, and harvesting work under severely wet conditions was practically impossible.

The present invention has been made in view of the above circumstances, and by improving the net receiving structure, it is possible to continue the threshing process without lowering the leakage efficiency even during wet threshing. To aim.

[Means for solving problems]

In order to achieve the above-mentioned object, the threshing device according to the present invention integrally forms a receiving net body with a resin having excellent water repellency, and has a large number in the longitudinal direction and the horizontal direction so as to form a mesh in the receiving net body. The surfaces of the wire rods arranged in parallel on the handling cylinder side are formed into convex curved surfaces, and the heights of the respective wire rods on the handling cylinder side are set to be the same so that the leakage lower surface of the net body is flush with each other, and A net-receiving vibrating mechanism for vibrating the net-receiving main body in the circumferential direction of the handling cylinder is provided by being connected to the net-receiving main body at an upper portion of the handling chamber on the side opposite to the handling port. Guided members are provided at both front and rear edges, and guide members are provided to guide the members in the circumferential direction of the handling cylinder while sandwiching the guided members above and below in the thickness direction of the net body. And

The operation and effect of this characteristic configuration are as follows.

[Action]

That is, in addition to forming a net body integrally with a resin having excellent water repellency that does not easily adhere to threshed products, and forming a convex curved surface on the handle side of the wire into which water droplets do not spread easily, By vibrating forcibly in the circumferential direction of the handling cylinder by the net vibrating mechanism, the processed material that has entered the opening of the leaking net is quickly dropped, and the wet or near the surface of the receiving net The treated product is easily separated from the net surface. Furthermore, since the leakage lower surface of the net body is made flush by setting the height of each wire rod on the handling cylinder side to be the same, for example, a vertical wire rod and a horizontal wire rod can be placed on the handle cylinder side. It is also possible to eliminate the problem that the higher wire caught on the lower wire hinders the movement of the wire to the saw and the processed material stays, as is different in the above. In addition, since the net-receiving vibrating mechanism is installed in the upper part of the handling room on the side opposite to the mouth, it is also connected to the net-receiving main body. In addition, the receiving net vibration mechanism does not hinder the movement of the culm.
Further, since the receiving net body is provided in such a manner that the guided members at both front and rear edges thereof are vertically sandwiched by the guide members in the thickness direction, vibration in the vertical direction is small and the receiving net body can be firmly held. become.

[Effect of device]

Therefore, continuous wet threshing is possible without drastically reducing the capacity, and because the leakage performance of the receiving net is high,
When the amount of wetness is low, it is possible to perform high-load threshing with a large amount of processed material, and it is possible to obtain a threshing device with high work efficiency, and also to place the receiving net vibration mechanism in a good position that does not hinder the movement of grain culms. In addition, the receiving net body can be firmly held without undue vertical vibration.
