Description
【０００１】[0001]
本考案は脱穀装置に関し、詳しくは、樹脂材で製作された受網を有する脱穀装 置の改良に関する。 The present invention relates to a threshing device, and more particularly, to improvement of a threshing device having a net made of a resin material.
【０００２】[0002]
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が存在し、この引例では格子状の濾過面と、枠部とが樹脂材 で一体的に構成されている。 Conventionally, as a net made of a resin material, for example, there is one shown in Japanese Utility Model Publication No. 36-15021. In this reference, the lattice-shaped filtering surface and the frame are integrally made of a resin material. It is configured.
【０００３】[0003]
ここで、前記引例のように格子状の濾過面を有する受網を用いる場合について 考察するに、扱室内では扱胴の回転方向に沿って処理物が高速で運動するため、 例えば、濾過面を形成する縦横夫々の格子部材の断面形状を等しくしたものでは 、一方の格子部材のみの摩耗が促進され、受網の寿命を短かくすることも考えら れ改善の余地がある。 本考案の目的は、長期に亘る使用によっても受網の濾過面には偏った摩耗を生 じ難い脱穀装置を構成する点にある。 Here, considering the case of using a net having a lattice-shaped filtering surface as in the above-mentioned reference, the processed object moves at a high speed in the handling room along the rotation direction of the handling cylinder. If the vertical and horizontal lattice members to be formed have the same cross-sectional shape, abrasion of only one of the lattice members is promoted, which may shorten the life of the net, and there is room for improvement. An object of the present invention is to construct a threshing device that is less likely to cause uneven wear on the filter surface of the net even after long-term use.

本考案の特徴は、扱胴の回転方向に沿って配置される多数の縦格子部材と、扱 胴の回転軸芯の方向に沿って配置される多数の横格子部材とで矩形の開口を多数 形成して受網を構成すると共に、縦格子部材の幅に対し、横格子部材の幅を大き く設定し、かつ、この受網を、高耐摩耗性、高撥水性の樹脂材で一体成形して成 る点にあり、その作用、及び効果は次の通りである。 A feature of the present invention is that a large number of rectangular lattice members are arranged along the rotation direction of the handling cylinder and a large number of horizontal lattice members are arranged along the direction of the rotation axis of the handling cylinder. In addition to forming the net, the width of the horizontal grid member is set to be larger than the width of the vertical grid member, and this net is integrally molded with a resin material with high wear resistance and high water repellency. The actions and effects are as follows.
【０００５】[0005]
上記特徴を例えば図１に示す如く構成すると、縦格子部材２４の幅Ｄ24に対し て、横格子部材２５の幅Ｄ25が大きく設定されているので、扱胴２の回転に起因 して高速で運動する処理物が摺接しても、縦横夫々の格子部材２４，２５の摩滅 量の均一化を図れる。When configured as shown the above characteristics in FIG. 1 for example, with respect to the width D 24 of the longitudinal grid members 24, the width D 25 of the transverse grid members 25 is set to be larger, due to the rotation of the threshing drum 2 Fast Even if the object to be moved is slidably contacted with each other, the wear of the lattice members 24 and 25 can be made uniform.
【０００６】[0006]
従って、格子部材の幅の設定という比較的簡単な改良によって、長期に亘る使 用によっても受網の濾過面には、偏った摩耗を生じ難い脱穀装置が構成されたの である。 Therefore, with the relatively simple improvement of setting the width of the grid member, a threshing device was constructed that was less likely to cause uneven wear on the filtration surface of the net even after long-term use.

本考案は脱穀装置に関し、詳しくは、樹脂材で製作された受網を有する脱穀装 置の改良に関する。 The present invention relates to a threshing device, and more particularly, to improvement of a threshing device having a net made of a resin material.
【０００２】[0002]
この種の脱穀装置で用いれる受網として、近年、合成樹脂材で格子状の網目を 一体的に樹脂成形することにより製作されたものが用いられてきている（例えば 、実公昭36-15021号公報または実開昭54-14964号公報参照）。 As a net used in this type of threshing device, in recent years, a net made by integrally molding a lattice-shaped mesh with a synthetic resin material has been used (for example, Japanese Utility Model Publication No. 36-15021). (See the official gazette or Japanese Utility Model Publication No. 54-14964).

樹脂成形した受網は、金属の線材を編んで製作した受網、いわゆるクリンプ網 のように、縦横の線材の交差部分において隙間が存在しないため、ワラ屑の喰い 込みを生じ難く、しかも、腐蝕を生じ難いという良好な面を有する。 又、金属製受網は撥水性が低いため、濡れた作物を脱穀する場合、濡れたワラ 屑が表面でベタつき受網に付着堆積して早期に目詰まりが発生するという欠点が あるのに対して、樹脂製受網は、撥水性、滑性が良くて濡れたワラ屑が表面に付 着し難いという特性を有し、この点で目詰まりが発生し難く濡れた作物の脱穀作 業にも強いという注目すべき長所がある。 その反面、旧来の樹脂製受網は、耐摩耗性、剛性に難点があり、扱胴によって 穀稈や処理物が、受網表面に強力にこすりつけられる際の摩耗、衝撃による破損 等のために、受網を比較的短期間のうちに交換する必要が生じることになり、こ の点において樹脂受網の実用化に問題があった。 つまり、樹脂受網は、金属線材で構成されるクリンプ網に比べては、面方向で のある程度の厚み幅を有した縦横の格子部材によって構成されるものであるが、 脱穀処理物の漏下粒度を制限する目的のためには網目開口を必要以上大きくする ことができず、それでいて、処理物の漏下をスムースに行わせるために所定以上 の開口率が必要である。このため、縦横夫々の格子部材の厚み幅が極力小さく制 限させられることから充分な強度を得難く、したがって、脱穀処理物に押されて 扱胴軸芯からの距離が変化するというような扱き性能の劣化につながる剛性の低 下や、前記の耐摩耗性の低下が問題となる。そして、単に充分な強度や耐摩耗性 を得ることだけを考えて格子部材を太く構成すると、開口率が低下し、如何に樹 脂受網とはいえ詰まり発生が生じ易くなって実用的ではない。 しかしながら、濡れた作物を支障なく脱穀できるようにとの強い要請があるこ とも事実で、この要請に基づき、プラスチック分野において、撥水性、滑性とと もに耐摩耗性に優れた高分子樹脂材が商品化されていることに着目して、樹脂受 網の開発に着手した。 本考案の目的は、所定の開口率で漏下面積を確保しながら脱穀性能に悪影響を 及ぼさない形状で、受網全体の寿命の向上を図り、撥水性、滑性に優れていると いう樹脂材の特性を生かして濡れた作物の脱穀にも強く、かつ、漏下性能の高い 樹脂製受網の実用化を図ることにある。 Unlike the so-called crimp net, which is produced by weaving metal wire rods, the resin-molded net does not have any gaps at the intersections of the vertical and horizontal wire rods, so it is difficult for bite debris to bite in and to corrode. It has a good aspect that it is unlikely to occur. In addition, since the metal net has a low water repellency, when threshing a wet crop, there is a drawback that wet debris sticks and deposits on the net and sticks to the net at an early stage. In addition, the resin net has the property of being water-repellent and of good lubricity, and making it difficult for wet debris to adhere to the surface, which is why clogging is less likely to occur and threshing operations for wet crops are difficult. There is a remarkable advantage that it is also strong. On the other hand, the conventional resin nets have drawbacks in wear resistance and rigidity, and because of the abrasion and impact damage caused by the rubbing of the grain culms and the processed material on the surface of the net strongly by the handling cylinder. However, it was necessary to replace the receiving net within a relatively short period of time, and there was a problem in putting the resin net into practical use in this respect. In other words, the resin net is composed of vertical and horizontal lattice members that have a certain thickness width in the plane direction compared to the crimp net made of metal wire, but The mesh opening cannot be made larger than necessary for the purpose of limiting the particle size, and yet an opening ratio of not less than a predetermined value is necessary for smooth leakage of the processed material. For this reason, it is difficult to obtain sufficient strength because the thickness widths of the vertical and horizontal lattice members are limited as small as possible.Therefore, the distance from the handling cylinder axis is changed by being pushed by the threshing material. There are problems such as a decrease in rigidity leading to deterioration of performance and a decrease in wear resistance as described above. If the lattice member is made thicker only in order to obtain sufficient strength and wear resistance, the aperture ratio will decrease, and clogging will occur easily even though the resin net is not practical. . However, it is also true that there is a strong demand for threshing wet crops without hindrance, and based on this demand, in the plastics field, polymer resin materials that are excellent in water repellency and lubricity as well as abrasion resistance are used. Focusing on the commercialization of resin, we started the development of resin nets. The object of the present invention is to ensure a leaking area with a predetermined opening ratio and not to adversely affect threshing performance, to improve the life of the whole receiving net, and to say that the resin is excellent in water repellency and lubricity. The aim is to put into practical use a resin net that is highly resistant to threshing of wet crops by taking advantage of the characteristics of the wood and has high leakage performance.

上記目的を達成するために講じた本考案の技術手段は、扱胴の回転方向に沿っ て配置される多数の縦格子部材と、扱胴の回転軸芯の方向に沿って配置される多 数の横格子部材とで、それらの縦格子部材と横格子部材とに囲繞される多数の矩 形の開口からなる網目を備えた受網を構成し、この受網を、前記縦格子部材の長 手方向に沿って前記扱胴の回転軸芯周りで往復揺動自在に装着するとともに、夫 々の網目部分における前記縦格子部材の網面に沿う方向での厚み幅に対し、横格 子部材の網面に沿う方向での厚み幅を大きく設定し、かつ、この受網を、高耐摩 耗性、高撥水性の樹脂材で一体成形した点にある。 The technical means of the present invention taken to achieve the above object includes a large number of vertical lattice members arranged along the rotation direction of the handling cylinder and a plurality of vertical lattice members arranged along the direction of the rotation axis of the handling cylinder. And a horizontal lattice member of the vertical lattice member and a horizontal lattice member, the net having a mesh of a large number of rectangular openings surrounded by the vertical lattice member and the horizontal lattice member. It is mounted so as to be capable of reciprocatingly swinging about the axis of rotation of the handling cylinder along the hand direction, and the horizontal grid member is different from the thickness width of each mesh portion in the direction along the mesh surface of the vertical lattice member. The point is that the thickness width in the direction along the mesh surface is set to a large value, and this mesh is integrally molded with a resin material having high abrasion resistance and high water repellency.

上記技術手段を講じたことによる作用は次の通りである。 前記の技術的課題に基づく研究の結果、次の事実が判明した。すなわち、扱胴 の回転に伴って扱室内の処理物は受網の縦格子部材の長手方向に沿って移動する ので、この縦格子部材は扱胴に面する表面が処理物の移動方向にほぼ沿う方向で の摺接によって比較的緩やかに摩耗してゆくのに対して、横格子部材には処理物 が交差する状態で衝突及び摺接してゆくのでこの横格子部材は縦格子部材よりも 単位時間当たりの摩耗が早いものとなる。 ここにおいて、本発明では、夫々の網目部分において、摩耗進行の早い横格子 部材の網面に沿う方向での厚み幅を、摩耗進行の遅い縦格子部材の幅よりも広幅 に設定する構成を採用することで、同一開口率のもとで両格子部材の夫々の厚み 幅を均等に構成する場合に比べて、横格子部材の厚み幅をより大きくすることが でき、その耐摩耗性を向上させられる。 そして、横格子部材が太くなった反面、同一開口率のもとでは縦格子部材の厚 み幅は小さくなっているが、格子部材全体としての厚み幅が削減される訳ではな く、必要強度が損なわれるものではない。 また、受網を縦格子部材の長手方向に沿って往復揺動自在させるので、脱穀処 理物に対して往復揺動による衝撃を与え、この点で受網の開口面積の割に目詰ま り少なく漏下させられるものである。しかも、合成樹脂材の特性である表面の撥 水性、滑性が優れている点を、目詰まりや摩耗軽減のために生かすことができ、 受網の往復揺動との相乗により、濡れた作物を脱穀しても、濡れたワラ屑や葉の 付着が生じにくく、漏下性能が良い。 The effect of taking the above technical means is as follows. As a result of the research based on the above technical problems, the following facts have been revealed. That is, as the handling cylinder rotates, the processed material in the handling chamber moves along the longitudinal direction of the vertical grid member of the net, so that the surface of the vertical grid member facing the handling cylinder is almost in the moving direction of the processed material. The slidable contact along the direction of wear causes the wear to occur relatively gently, while the horizontal grid member collides and slides in contact with the workpieces in a crossed state. Wear per hour will be faster. Here, in the present invention, in each mesh portion, the thickness width in the direction along the mesh surface of the horizontal lattice member with fast wear is set to be wider than the width of the vertical lattice member with slow wear. By doing so, it is possible to make the thickness width of the horizontal lattice member larger and improve its wear resistance compared to the case where the thickness widths of both lattice members are made uniform under the same aperture ratio. To be While the horizontal lattice members are thicker, the thickness of the vertical lattice members is smaller under the same aperture ratio, but the thickness of the lattice members as a whole is not reduced, and the required strength is Is not impaired. In addition, since the receiving net is allowed to reciprocally swing along the longitudinal direction of the vertical lattice member, a shock due to the reciprocating swing is given to the threshing treatment object, and at this point, the opening area of the receiving net is clogged. It is a small leak. Moreover, the excellent water repellency and lubricity of the surface, which are the characteristics of synthetic resin materials, can be utilized to reduce clogging and wear, and in combination with the reciprocating swing of the receiving net, wet crops can be used. Even after threshing, it is difficult for wet straw chips and leaves to adhere and the leakage performance is good.

【考案の効果】 以上説明したように、本考案によれば、表面の撥水性、滑性が優れている合成 樹脂材で受網を成形し、かつ、その受網を扱胴軸芯周りで往復揺動自在に装着す ることで、穀粒漏下性能に優れ、しかも、ワラ屑などの付着による目詰まりを抑 制して、濡れ脱穀時にも高い処理能力を発揮させることができる高性能の脱穀装 置を得られた。 しかも、受網の格子仕様を合理的に設定することで、縦格子部材に対する横格 子部材の先行摩耗・破損のために受網を早期に交換するようなことがなく、受網 全体の寿命を向上して長期間使用することができ、実用上有効な受網とすること ができた。As described above, according to the present invention, the net is formed of a synthetic resin material having excellent water repellency and lubricity on the surface, and the net is placed around the handling cylinder axis. By installing it so that it can swing back and forth, it has excellent grain leakage performance, and it also suppresses clogging due to the adherence of straw debris, etc. Threshing equipment was obtained. Moreover, by reasonably setting the grid specifications of the receiving net, there is no need to replace the receiving net early due to preceding wear or damage to the horizontal grid member with respect to the vertical lattice member, and the life of the entire receiving net is reduced. It was possible to improve the service life and use it for a long time, and it was possible to obtain a practically effective receiving network.
