Description

TECHNICAL FIELD The present invention relates to a structure of a threshing net formed of a resin material.

[Conventional technology]

Conventionally, as a net made of a resin material, for example, Jitsuko Sho 36
-15021 gazette, as shown in Japanese Patent Publication No. 15021,
It is known that a peripheral mounting frame portion and a mesh partitioning projection portion are integrally molded with a resin material.

The receiving net integrally molded with the resin material has advantages that straw dust does not bite into the connecting portions of the vertical and horizontal lattice members to cause clogging, it is easy to manufacture, it is lightweight, and it does not corrode. .

[Problems to be solved by the invention]

Resin-made nets have various advantages over ordinary crimp nets, but on the other hand, they are inferior to metal nets in terms of mechanical strength, which makes them practical. It becomes a big problem of.

In the above-mentioned known example, the peripheral mounting frame portion is made wide, and the strength is increased by arranging an arc-shaped mesh partitioning protrusion in the middle of the leakage lower surface, but the strength required only with the resin material is provided. In order to obtain it, it is necessary to make the resin thickness considerably thick, which makes it difficult to form a leaky lower surface with a desired opening ratio, and until now, the resin-integrated molding net has been put to practical use. There wasn't.

The present invention has been made by paying attention to such actual circumstances, and it has been made possible to put the resin net which brings various advantages into practical use by improving the support and reinforcement of the resin net. It is a thing.

[Means for solving problems]

A feature of the present invention is that the receiving net disposed along the handling cylinder is integrally formed of a resin material and is attached to the airframe through a frame. Inside, a mounting frame portion for screw connection to the frame is integrally formed, and the bow metal arranged on the mounting frame portion is fixed to the frame by tightening together with the mounting frame portion, and in the frame, The reinforcing member is provided with a reinforcing frame for receiving and supporting the lattice member constituting the leaking bottom surface from below along the longitudinal direction thereof, and the width of the reinforcing frame is set to be smaller than the width of the lattice member. , And the effects are as follows.

[Action]

According to the configuration of the present invention, in the resin receiving net, the mounting frame portions formed around the leaky lower surface and inside the leaky lower surface are screw-connected to the metal frame, so that the strength of the entire receiving net is high. And the frame supporting it is sufficiently kept, the mounting frame can be suppressed to the width required for screwing, and the leakage lower surface can be made large in the net having a limited area.

Also, since a metal bow is jointly fastened and connected to some of the mounting frame parts, the strength of this part is even higher, and the processed product is pressed against the receiving net side as the handling cylinder rotates. It can face various loads enough.

In addition, the reinforcing frame provided in the frame receives the leaking lower surface from below and counters the threshing load that pushes the leaking lower surface outward, and
In this case, the reinforcing frame is hidden behind the lattice member that constitutes the leakage lower surface, so that the leakage performance is not adversely affected.

In addition, as shown in the examples, when a high molecular weight polyethylene having high abrasion resistance and impact resistance and high water repellency is used as the material of the net, it becomes possible to use it for a long period of time and also at the time of wet threshing. It is possible to perform continuous work because it is unlikely that straw chips will adhere.

〔The invention's effect〕

As described above, according to the present invention, the mounting frame portion of the net is made too wide by rationally supporting the resin-integrated net with the frame with the reinforcing frame and the bow. It was possible to attach the receiving net to the airframe without the necessary strength.

As a result, it was possible to increase the leakage area and improve the leakage efficiency, and also to put a resin net having various advantages into practical use.
