Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は脱穀装置の受網に関し、詳しくは、樹脂材で製
作された受網に関する。[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.
従来、樹脂材で製作された受網としては、例えば実公昭
36-15021号公報に示されるもののように、格子状の漏下
面を樹脂材で体成形したものが知られている。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.
漏下面を樹脂材で一体成形した受網は、金属線を編んだ
クリンプ網のように金属線の交差部にワラ屑がささり込
んで付着することがなく、かつ、金属網に比較して付着
物が剥離しやすいために、濡れた作物の脱穀を漏下面の
目づまりを抑えながら行える利点を有するものである
が、金属網に比較して強度的に劣るために現在まで実用
化には至っていなかった。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.
つまり、脱穀用の受網は、脱穀圧力が扱胴側から強力に
働くために、強度の低い樹脂製受網はその漏下面が反扱
胴側に押圧変形されてしまい、扱胴と受網との間隔が増
大して扱き残しが発生するとともに、穀粒の単粒化性能
が低下することになり、実用上に難点があったのであ
る。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.
樹脂製受網の強度を高める手段としては、網の厚さを大
きくしたり、漏下面を形成する格子部材の幅を大きくす
る等の手段も考えられるが、前者では漏下孔の長さが大
きくなって漏下性能が低下しがちとなり、後者では漏下
面の開口率が低下することになり、実用的ではない。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.
本考案は、このような点に着目してなされたものであっ
て、受網全体の厚さを大きくすることなく、かつ、漏下
面の開口率を低くすることなく、大きい強度でもって使
用することができる樹脂製の受網を提供することを目的
とする。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.
上記目的を達成するための本考案に係る脱穀装置の受網
は、格子状の漏下面を樹脂材で一体成形するとともに、
この漏下面を構成する格子部材を、該格子部材に沿うよ
う配備された支持フレームで反扱胴側から受止め支持
し、かつ、この支持フレームの幅を前記格子部材の幅よ
り狭く設定した構成とした。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
上記特徴を例えば第1図に示すように構成すると、漏下
面(4F)を形成する格子部材(4B)の幅(G)より小さい幅(F)
の支持フレーム(18)が反扱胴側に位置するので、漏下面
(4F)に対して扱胴側から大きい圧力が作用した場合に
は、支持フレーム(18)によって格子部材(4B)が受け止め
られて漏下面(4F)を大きく変形させることが無く、しか
も、支持フレーム(18)は格子部材(4B)の幅内に位置する
ので漏下面(4F)に対する処理物の通過を妨げ無い。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).
従って、板状に樹脂材で成形されて成る受網に対して大
きい圧力が扱胴側から作用した場合でも、漏下面の変形
が抑えられ、扱胴と受網との間隔を大きくすることなく
良好な脱穀を行うことができ、しかも、受網を大きい強
度を持って支持できるものでありながら、漏下面での漏
下性能及び開口率を低下させることがなく、もって樹脂
製受網の実用化を可能にすることができた。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.
