Description
【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に搭載される脱穀装置に係り、特に
扱胴の下側に沿って配置される円弧状の受網の構造に特
徴を有する脱穀装置に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a threshing device mounted on a combine, and is particularly characterized by the structure of an arcuate receiving net arranged along the lower side of the handling barrel. Regarding threshing equipment.
コンバインに搭載される脱穀装置においては、濡れ脱穀
時における受網の目詰まり低減、及び受網からの穀粒漏
下性能向上を図る為に、受網を扱胴の円周方向に沿って
強制的に振動させることが提案されている。In the threshing device mounted on the combine, the net is forced along the circumferential direction of the handling cylinder in order to reduce the clogging of the net during wet threshing and to improve the grain leakage performance from the net. It has been proposed to mechanically vibrate.
前記受網は金属製の受網フレームに金属製のクリンプ網
を取り付けたような構造で、受網の重量が比較的重いも
のとなっている為に、この受網を振動駆動するには比較
的大きな動力が必要となっている。The receiving net has a structure in which a metal crimping net is attached to a metal receiving net frame, and the weight of the receiving net is relatively heavy. A huge amount of power is needed.
又、受網を振動機構するとなると、扱室側にレールのよ
うなガイドを設けると共に、受網にローラーを取り付け
て受網のローラーを前記ガイドに乗せ付け受網を扱胴の
円周方向に移動可能に支持し、さらに受網がガイドから
浮き上らないようにする押さえ部材等が必要になってく
る。In addition, when the receiving net is a vibrating mechanism, a guide such as a rail is provided on the side of the handling room, a roller is attached to the receiving net, the roller of the receiving net is placed on the guide, and the receiving net is placed in the circumferential direction of the handling cylinder. It is necessary to provide a pressing member that movably supports the net and prevents the net from floating from the guide.
ここで、本考案は前述のような問題に着目してなされた
ものであり、消費動力及び構造の複雑化を抑えながら受
網の振動構造を得ることを目的としている。Here, the present invention has been made in view of the above-mentioned problems, and an object thereof is to obtain a vibrating structure of a receiving net while suppressing power consumption and complexity of the structure.
本考案の特徴は以上のような脱穀装置において、扱胴の
下側に沿って配置される円弧状の受網を樹脂材で一体成
形し、この受網の網目を、網内面側が突曲形状の格子状
部分によって形成すると共に、前記受網の円弧状側辺を
板状面に形成し、その板状面部を直接に上下から支持し
て受網を扱胴の円周方向に沿って摺接移動可能に案内す
るガイドと、受網をガイドに沿って設定ストロークで強
制振動させる受網振動機構を備えてあることにあり、そ
の作用及び効果は次のとおりである。The feature of the present invention is that, in the threshing device as described above, an arc-shaped receiving net arranged along the lower side of the handling cylinder is integrally molded with a resin material, and the mesh of this receiving net has a curved inner surface side. And the arc side of the net is formed into a plate surface, and the plate surface is directly supported from above and below to slide the net along the circumferential direction of the handling cylinder. The present invention is provided with a guide that guides so that the net can move in contact, and a receiver net vibration mechanism that forcibly vibrates the receiver net at a set stroke along the guide, and the operation and effect are as follows.
前述のように受網全体を樹脂材で一体成形すると受網全
体の軽量化が図れるので、これにより受網の振動駆動用
の消費動力を抑えることができるのである。このように
受網を樹脂製とすると振動駆動中に受網が浮き上がって
扱胴の扱歯に接触するおそれが生ずるが、受網の円弧状
側辺をガイドにより上下から挾み込むように支持してい
る為に、受網は扱胴より一定間隔を維持した状態で振動
駆動されることになる。As described above, if the entire receiving net is integrally molded with a resin material, the overall weight of the receiving net can be reduced, so that the power consumption for vibration driving of the receiving net can be suppressed. If the net is made of resin in this way, the net may float during vibration drive and come into contact with the handle teeth of the handle cylinder, but the arc side of the net is supported by a guide so that it is sandwiched from above and below. Therefore, the receiving net is oscillated and driven while maintaining a constant distance from the handling cylinder.
そして、従来構造において用いられていたローラー及び
その支持構造（支持軸及びベアリング等）が不要となっ
て構造の簡略化が図れる。また、ガイドにより上下から
挾み込まれる受網の前記円弧状側辺を板状面に形成し
て、その板状面部をガイドで案内するので、特に潤滑油
等を用いなくても樹脂の滑動性を利用して円滑に摺動が
行われる。Further, the roller and its supporting structure (supporting shaft, bearing, etc.) used in the conventional structure are not required, and the structure can be simplified. Further, since the arcuate side of the net that is sandwiched by the guide from above and below is formed into a plate-like surface and the plate-like surface portion is guided by the guide, sliding of the resin is possible even without using lubricating oil or the like. Sliding is performed smoothly by utilizing the property.
さらに、受網の網目を、網内面側が突曲形状の格子状部
分によって形成するので、処理物が受網に堆積し難い。Furthermore, since the mesh of the net is formed by the lattice-shaped portion having the curved inner surface, the processed material is hard to deposit on the net.
以上のように、脱穀装置において受網の軽量化を図るこ
とにより、振動駆動用の消費動力を抑えることができる
ようになって動力の節約ができるようになると共に、樹
脂の性質を有効に利用して円滑で構造の簡単な受網の振
動構造が得られ、製作コストの低減を図ることができ、
しかも処理物が受網に堆積し難いので網の目詰まりを防
止できた。As described above, by reducing the weight of the net in the threshing device, it becomes possible to reduce the power consumption for driving the vibration, save power, and effectively use the properties of the resin. As a result, a vibrating structure of the receiving net that is smooth and has a simple structure can be obtained, and the manufacturing cost can be reduced.
Moreover, it is difficult to deposit the treated material on the net, so that the net can be prevented from being clogged.
