Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a net for a threshing device, and more particularly to a net made of a resin material.

[Conventional technology]

Conventionally, as a net made of resin material, for example,
As disclosed in Japanese Patent Publication No. 36-15021, there is known one in which a lattice-shaped leaky lower surface is formed of a resin material.

[Problems to be solved by the invention]

Unlike the crimp net made by braiding metal wire, the net with the leaked lower surface integrally molded does not cause straw dust to stick to the intersections of the metal wire and stick to it. Since the kimono can be easily peeled off, it has the advantage of being able to thresh wet crops while suppressing the clogging of the leaking bottom surface, but it is inferior in strength to metal nets and has not yet been put into practical use. There wasn't.

In other words, in the threshing receiving net, the threshing pressure acts strongly from the handling barrel side, so that the leaking lower surface of the resin receiving net with low strength is pressed and deformed to the opposite handling barrel side, and the handling barrel and the receiving net are There was a problem in practical use because the interval between and increased, and untreated material was left unremoved, and the grain-separating performance of the grain decreased.

As a means for increasing the strength of the resin net, it is conceivable to increase the net thickness or increase the width of the lattice member forming the leak lower surface, but in the former case, the length of the leak hole is If the latter is used, the leakage performance tends to deteriorate, and in the latter case, the aperture ratio of the leakage lower surface decreases, which is not practical.

The present invention has been made paying attention to such a point, and it is used with a large strength without increasing the thickness of the whole receiving net and without lowering the opening ratio of the leakage lower surface. It is an object of the present invention to provide a resin net that can be used.

[Means for Solving the Problems]

In order to achieve the above object, the receiving net of the threshing device according to the present invention has a lattice-shaped leaky lower surface integrally molded with a resin material,
A structure in which the lattice member forming the leaking lower surface is received and supported by a support frame provided along the lattice member from the counter-handling cylinder side, and the width of the support frame is set narrower than the width of the lattice member. And

[Action]

When the above features are configured as shown in FIG. 1, for example, the width (F) smaller than the width (G) of the lattice member (4B) forming the leaking lower surface (4F).
Since the support frame (18) of the
When a large pressure is applied to the (4F) from the handle side, the support frame (18) does not catch the lattice member (4B) and the leakage lower surface (4F) is not significantly deformed. Since the frame (18) is positioned within the width of the lattice member (4B), it does not prevent the processed material from passing through the leakage lower surface (4F).

[Effect of device]

Therefore, even if a large pressure is applied to the receiving net made of a resin material in a plate shape from the handling cylinder side, the deformation of the leakage lower surface is suppressed, and the distance between the handling cylinder and the receiving net is not increased. Good threshing can be performed and the net can be supported with great strength, but it does not reduce the leakage performance and the opening ratio on the leak lower surface, and thus the practical use of the resin net is possible. Could be made possible.
