Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、脱穀装置に装備される樹脂製の受網の構造に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of a resin net which is installed in a threshing device.
従来における上記の脱穀装置の受網構造としては、例え
ば特開昭63−248318号公報に開示されているように、受
網を高分子量ポリエチレンで一体成形して構成するとと
もに、扱胴の扱歯と受網との隙間を穀稈がすり抜けてし
まうことが原因で扱き残しが発生するのを阻止するため
の弓金を、その両端と中間部との３箇所において、受網
の内面側からビス止めするよう構成するものがあった。As a conventional net-receiving structure of the threshing device, for example, as disclosed in Japanese Patent Laid-Open No. 63-248318, the net is integrally formed of high-molecular-weight polyethylene, and the tooth of the handle is treated. Bow wires for preventing leftovers from being left behind due to the grain culm slipping through the gap between the net and the net, and screws from the inner surface side of the net at three points, both ends and the middle part. Some were configured to stop.
上記従来構造では、樹脂製受網に弓金を取付けるため
に、溶接等の全幅固着は不可能であるので、適宜箇所を
ビス止めするよう構成したものであるが、固定部以外の
中間領域では、弓金は受網内面に接当しているのみであ
るので、脱穀処理物が多い場合等において弓金の中間部
に対して横向き荷重が加わり、撓み変形することがあ
り、又、ビス止め部にダレが生じてガタつき、その結果
弓金がはずれてしまうおそれもあった。In the above-described conventional structure, since the full width fixing such as welding is impossible because the bow is attached to the resin receiving net, it is configured to be screwed at an appropriate position, but in an intermediate region other than the fixing portion. Since the bow metal is only in contact with the inner surface of the receiving net, a lateral load may be applied to the middle part of the bow metal when there are many threshing products, and it may bend and deform. There was a risk that the parts would sag and rattle, resulting in the dislodgement of the bow.
本考案は、簡単な構造改良で上記不具合点を解消するこ
とを目的としている。An object of the present invention is to solve the above-mentioned problems by a simple structural improvement.
本考案の特徴は、扱胴の回転軌跡に沿って配置される受
網を、高耐摩耗性、高撥水性の樹脂材で一体形成すると
ともに、この受網表面に弓状部材を複数箇所で取付け固
定し、取付け固定部以外の領域において、弓状部材から
突設した突片を受網に形成した嵌合孔に嵌め込み装着し
てある点にあり、その作用・効果は次の通りである。The feature of the present invention is that the net, which is arranged along the rotation trajectory of the handling cylinder, is integrally formed of a resin material having high wear resistance and high water repellency, and an arcuate member is formed at a plurality of points on the surface of the net. It is mounted and fixed, and in the area other than the mounting and fixing portion, the protruding piece protruding from the arcuate member is fitted and mounted in the fitting hole formed in the receiving net. Its action and effect are as follows. .
つまり、前記受網は摩耗が少なく長期的の使用に耐え、
かつ、水分を多く含む穀稈を扱処理する場合でも水分の
付着がなく目詰りを抑制できる。しかも、金属線を編ん
で網目を形成したクリンプ網構造に比較して、一体成形
網目を形成するので、処理物の引っ掛かりや詰まりが発
生しにくい。そして、弓状部材を複数箇所で取付け固定
して位置固定するとともに、突片を嵌合孔に嵌め込み、
これらの嵌合により、固定部以外における弓状部材の横
荷重を高耐摩耗性の樹脂材である受網で受止め支持でき
るので、数少ない固定部での取付けるものでありながら
弓状部材の撓み変形や受網における弓状部材固定部のダ
レの発生を抑止できる。In other words, the receiving net wears little and withstands long-term use,
Moreover, even when the grain culm containing a large amount of water is treated, clogging can be suppressed because water does not adhere. Moreover, since the integrally formed mesh is formed as compared with the crimp mesh structure in which the mesh is formed by knitting the metal wire, catching or clogging of the processed material is less likely to occur. Then, the arcuate member is attached and fixed at a plurality of positions to fix the position, and the projecting piece is fitted into the fitting hole.
Due to these fittings, the lateral load of the bow-shaped member other than the fixed part can be received and supported by the net which is a highly wear-resistant resin material, so that the bow-shaped member can be flexed even though it is mounted at a few fixed parts. It is possible to prevent deformation and sagging of the bow-shaped member fixing portion in the receiving net.
従って、本考案によれば、樹脂材により一体成形するこ
とで嵌合孔を簡単に形成することができ、しかも、弓形
形状に成形加工する必要がある弓状部材に嵌め込み用の
突片を突設するという簡単な構造改良により、又、前記
取付け固定部を隙間なく多数設けて組付け工数を増加さ
せるといった手間を掛けることなく、簡易な組付け作業
により、弓状部材の強固な支持を行えることとなった。Therefore, according to the present invention, it is possible to easily form the fitting hole by integrally molding the resin material, and to project the fitting projection piece to the bow-shaped member which needs to be formed into the bow-shaped shape. By providing a simple structural improvement, and without the trouble of increasing the number of assembling fixing portions without gaps to increase the number of assembling steps, a simple assembling work can firmly support the arched member. It became a thing.
以下、本考案の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
