Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bow on a inner surface of a resin receiving net arranged along a lower side of a handling cylinder and at a plurality of positions in a direction of a handling cylinder axis. The present invention relates to a net receiving structure of a shell removing device provided with gold.

[Conventional technology]

Compared to metal-made nets with wires, resin-made nets have less adhesion of straw chips during wetting and shelling, and also have the advantage that straw chips do not narrow at the intersections of wires. However, it has a disadvantage that it is easily worn as compared with a metal receiving net.

Generally, in a net receiving structure of a shell removing device, a portion corresponding to a tip portion on the front side in the axis direction of the handling cylinder tends to wear out early with the shell removing process.

Conventionally, in the receiving net of the above-mentioned shell removing device, since the bow metal for loosening the entanglement of the unshelled material is disposed at the substantially middle portion and the rear portion in the axial direction of the cylinder with respect to the receiving net and integrally welded, If the tip side of the part became worn, the entire receiving net was replaced.

[Problems to be solved by the invention]

In a structure in which the entire receiving network is replaced, there is an inconvenience that replacement costs are high.

Therefore, as a means for solving the above-mentioned disadvantage, it is conceivable to increase the durability by increasing the thickness of the wire forming the mesh,
In such a case, not only does the weight of the receiving net whose weight is desirably reduced for the attachment and detachment of cleaning or the like increase, but also the mesh becomes small, and if the mesh is enlarged, the absolute amount of the mesh with respect to the receiving net becomes insufficient. There is an inconvenience that the leakage rate decreases.

An object of the present invention is to increase the durability of a receiving net without increasing the weight of the receiving net and without reducing the leakage rate.

[Means for solving the problem]

The net receiving structure of the shell removing apparatus according to the present invention is configured such that a bow is protruded at an inner surface of a resin receiving net arranged along the lower side of the handling cylinder and at a plurality of positions in the axial direction of the handling cylinder. A net receiving structure of a shell removing device, wherein the receiving net is turned forward and backward so as to be mountable on the shell removing device, and the plurality of metal bows are provided so as to be positioned symmetrically in front and rear or substantially symmetrically. This is a characteristic configuration.

 The operation and effect are as follows.

[Action]

When the front end of the receiving net is worn, the receiving net is turned around in the horizontal plane and mounted on the shelling device, so that the rear side with relatively little wear can be used.
Even after the change of the orientation, the function of each bow does not change from that before the change.

Further, since the metal bow is formed, the durability against abrasion and the like is higher than that of, for example, a structure in which a bow-shaped structure is integrally formed with a resin receiving net. Therefore, it is possible to avoid a problem that the receiving net as a whole must be replaced with a new one due to abrasion of the bow-shaped structure despite the fact that the receiving net can be used by inverting the receiving net.

〔The invention's effect〕

As described above, the receiving net is turned upside down so that it can be mounted on the shelling device, and the metal net is constructed so that the durability of the receiving net as a whole increases, and the durability of the receiving net is increased. As compared with the case where the wire forming the mesh is made thicker to increase the service life, the weight of the receiving net can be reduced, and the work of attaching and detaching the receiving net can be easily performed. , The processed material can be satisfactorily leaked.

〔Example〕

The drawing shows a receiving net of the shell removing device mounted on the combine, and an arc-shaped receiving net (2) is arranged below the handling cylinder (1). The receiving net (2) is integrally formed of an ultrahigh molecular weight polyethylene material having excellent wear resistance and water repellency, and is fixed to a frame (3) on the shell removing device side via a bolt (4).

On the inner surface of the receiving net (3), a pair of front and rear bows (5) and (6) are provided symmetrically in the front-rear direction so as to divide the receiving net (2) into three equal parts in the direction of the axis of the handling cylinder. , Even if the receiving network (2) is reversed and replaced, the bow metal (5), (6)
Are set to have the same positional relationship as before the inversion.

The bows (5) and (6) are used to loosen the entanglement of the shelled material, that is, by passing the shelled material over the bow metal to form straw and shell particles. The bow metals (5) and (6) are:
Each of the mounting brackets (5A) and (6A) is fitted into the fitting recess (2A) of the receiving net (2), and is fixed by screws (7).

When three bows are used, the middle bow is located at the front and rear center of the receiving net (2), and the front and rear bows are arranged at an equal distance from the bow.

Further, in the claims, reference numerals are written for convenience of comparison with the drawings, but the present invention is not limited to the structure of the attached drawings by the entry.
