【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、コンバインやハーベスタに搭載される脱穀機
の受網構造に関し、詳しくは、合成樹脂材料で製作され
た受網の構造に関する。
DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a net structure of a thresher mounted on a combine or a harvester, and more specifically to a net structure made of a synthetic resin material.

〔従来の技術〕 従来、合成樹脂材料で製作された脱穀機用の受網として
は、例えば実公昭36−15021号公報に示されるように、
格子状の漏下面、及び周辺の取付け枠部分を合成樹脂材

[Prior Art] Conventionally, as a net for a thresher made of a synthetic resin material, for example, as shown in Japanese Utility Model Publication No. 36-15021,
It is known that the lattice-shaped leakage lower surface and the peripheral mounting frame portion are integrally formed of a synthetic resin material.

合成樹脂材料で一体成形された受網は、縦横の格子部材

等の利点を有するものである。
The receiving net integrally molded of synthetic resin material has the advantages that it is easy to manufacture, lightweight, and does not corrode, because it does not cause clogging due to straw dust entering the connecting parts of the vertical and horizontal lattice members. Is to have.

〔考案が解決しようとする課題〕[Problems to be solved by the device]

上記のように、合成樹脂製の受網は、金属線を編んで形
成したクリンプ網に比較して、藁屑の付着が少ないな
ど、合成樹脂特有の種々の利点を発揮するのであるが、
その反面、機械的な強度、特に曲げ強度の面では金属製

となっている。
As described above, the synthetic resin receiving net exhibits various advantages peculiar to the synthetic resin, such as less attachment of straw waste, as compared with a crimp net formed by knitting a metal wire,
On the other hand, it is inferior to the metal receiving net in terms of mechanical strength, particularly bending strength, which is a problem in practical use.

つまり、脱穀装置においては、扱胴と受網との間に穀稈

き残しが発生しやすくなるものである。
That is, in the threshing device, since a grain culm is supplied between the handling barrel and the net to perform threshing treatment, a large processing pressure from the handling barrel acts on the lattice-like leakage lower surface of the net, The receiving net tends to recede and deform away from the handling cylinder. When the leaking lower surface of the catching net recedes and deforms in this way, the distance between the catching teeth projecting on the outer periphery of the handling cylinder and the catching net becomes large, the threshing performance deteriorates, and leftovers easily occur.

もちろん、受網の厚さを大きくすれば、それだけ強度も
高まるが、漏下面の目合いの大きさが定められている条
件下で受網の厚さが大きくなると、目合いの大きさに比
較してその奥行きが長くなって、付着しにくい合成樹脂
材料といえども、殊にワラ量の割合が多くなる送塵口側
では目詰まりが生じやすくなり、受網の厚さをむやみに
厚くすることはできないのである。
Of course, if the thickness of the net is increased, the strength is also increased, but if the thickness of the net is increased under the condition that the size of the leakage bottom surface is determined, it will be compared to the size of the mesh. Even if it is a synthetic resin material that is difficult to adhere due to its longer depth, clogging easily occurs especially on the dust inlet side where the ratio of the amount of straw is large, and the thickness of the receiving net becomes unnecessarily thick. You can't do that.

また、漏下面を形成する格子部材の幅を大きくして漏下
面の強度を高めるとすれば、漏下面の開口率が小さくな
って漏下性能が低下してしまうことになる。
Further, if the width of the lattice member forming the leakage lower surface is increased to increase the strength of the leakage lower surface, the aperture ratio of the leakage lower surface is reduced and the leakage performance is deteriorated.

このように、樹脂製受網は、その強度をいかに確保する
かが実用化を図る上での重要な課題となっているのであ

As described above, how to secure the strength of the resin net is an important issue for practical use.

本考案の目的は、このような実情に着目してなされたも

In order to achieve the above-mentioned object, the threshing machine receiving net structure according to the present invention is a lattice member that integrally forms the entire receiving net provided in the lower part of the handling chamber with a synthetic resin material and constitutes a leaking lower surface of this net. Is formed in a vertically long shape having a larger dimension in the direction perpendicular to the leak lower surface than in the direction along the leak lower surface, and the mesh of the catch net in the longitudinal direction of the object to be processed in the handling chamber. The mesh size of the threshing machine is set so that the mesh size is small on the inlet side of the handling room and large on the dust inlet side.

In other words, in constructing a net integrally molded of synthetic resin material, the mesh size of the leakage lower surface is small on the inlet side of the handling chamber and large on the dust outlet side, and the lattice forming the lower surface of the leakage. The cross-sectional shape of the member itself is set to be vertically long so that deformation in the direction perpendicular to the surface of the leakage bottom surface does not easily occur. Therefore, on the inlet side of the handling chamber, the mesh density is increased and the strength of the lattice member is increased by synergizing with the cross-sectional shape having a large pressure resistance strength. The leakage efficiency of the substance can be improved.
