本発明は、扱胴の下側に沿って配置される円弧状の受網
の内面に、且つ、扱胴軸芯方向の略中間部と後部に、弓
金を突設してある脱穀装置の受網構造に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a structure in which a wire is provided on the inner surface of an arc-shaped receiving net disposed along the lower side of the handling cylinder, and at a substantially intermediate portion in the axial direction of the handling cylinder. This invention relates to a receiving net structure of a threshing device having a bow metal protruding from the rear part.
一般に脱穀装置の受網構造は、扱胴軸芯方向における。 Generally, the receiving net structure of a threshing device is in the axial direction of the handling cylinder.
前部側の穂先部分に対応する箇所が脱穀処理に伴って早
期に摩耗する傾向にある。The area corresponding to the tip of the ear on the front side tends to wear out early during the threshing process.
従来、上記脱穀装置の受網は、弓金が受網に一体的に溶
着さ、れていた為、前部の穂先側部分が摩耗すれば受網
全体を取り替えていた。Conventionally, in the receiving net of the above-mentioned threshing device, the bow metal was integrally welded to the receiving net, so if the front part on the ear side wore out, the entire receiving net had to be replaced.
受網全体を取り替える構造のものでは、取り替えの為の
コストが高くつくといった不都合がある。A structure in which the entire receiving net is replaced has the disadvantage that the replacement cost is high.
そこで、上記欠点を解消する手段として、網目を形成す
る線材を太（して耐久性を増すことが考えられるが、斯
かる場合には、清掃等の着脱の為に軽量化が望ましい受
網の重量が増大するばかりでなく、網目が小さくなり、
その網目を大きくすると、受網に対する網目の絶対量が
不足して漏下率が低下するといった不都合が生じる。Therefore, as a means to eliminate the above-mentioned drawbacks, it may be possible to increase the durability by making the wire material that forms the mesh thicker. Not only does the weight increase, but the mesh becomes smaller,
If the mesh is made larger, the absolute amount of the mesh relative to the receiving net is insufficient, resulting in a disadvantage that the leakage rate decreases.
本発明は、受網の重量を増大させることなく、又、漏下
率を低下させることなく、受網の耐久性を増大させるこ
とを目的とする。An object of the present invention is to increase the durability of a receiving net without increasing the weight of the receiving net or reducing the leakage rate.

を前後反転して装着可能に構成するとともに、前記後部
の弓金を受網に対して着脱自在に装着し、かつ、前記後
部の弓金を装着するための取付部を受網の前部に設けた
点にあり、その作用、効果は次の通りである。The characteristic configuration of the present invention for achieving the above object is that the receiving net is configured to be able to be attached by reversing the receiving net front and back, and the bow metal at the rear part is detachably attached to the receiving net; The main feature is that a mounting part for attaching a bow metal is provided at the front part of the receiving net, and its functions and effects are as follows.
受網の前部の穂先側部分が摩耗してくると、受網を水平
面内で回転させて、比較的摩耗の少ない後部側を利用す
るようにしたから、受網の耐久年数を増大させることが
できるに至った。When the front tip side of the catch net becomes worn, the catch net is rotated in a horizontal plane and the rear side, which is relatively less worn, is used, increasing the lifespan of the catch net. I was able to do it.
上記構成の結果、網目を形成する線材を太くして耐久年
数を増大させる場合に比して、受網の軽量化がはかれ、
受網の着脱作業が容易に行えるとともに、受網に対する
網目の絶対量を確保して処理物を良好に漏下できる。As a result of the above configuration, the weight of the receiving net can be reduced compared to the case where the wire rods forming the mesh are made thicker to increase the durability life.
The work of attaching and detaching the receiving net can be easily performed, and the absolute amount of mesh relative to the receiving net can be ensured to ensure good leakage of the processed material.

レーム（３）にボルト（４）を介して固定されている。The drawing shows the receiving net of the threshing device mounted on the combine harvester.
An arc-shaped receiving net (2) is arranged below the handling cylinder (1). The receiving net (2) is integrally molded from ultra-high molecular weight polyethylene material with excellent wear resistance and water repellency, and is fixed to the frame (3) on the threshing device side via bolts (4).
前記受網（２）の内面には、その扱胴軸芯方向の略中間
部と後部に弓金（５）、（６）が設けられている。Bow metals (5) and (6) are provided on the inner surface of the receiving net (2) at approximately the middle and rear portions in the axial direction of the handling cylinder.

、各取付ブラケット（５ａ）。The bow metals (5) and (6) are used to loosen the tangles of the threshed material. In other words, by letting the threshed material ride over the bow metal, it is separated into straw waste and grains. The bow metals (5) and (6) are separate mounting brackets (5a).
（６ａ）が受網（２）の嵌合用凹部（２Ａ）に嵌め込ま
れていてビス（７）にて固定されている。(6a) is fitted into the fitting recess (2A) of the receiving net (2) and fixed with screws (7).

部（２Ｂ）が設けられている。Then, the receiving net (2) is attached to the front part of the inner surface of the receiving net (2).
A fitting recess (2B) is provided with a screw hole as a mounting portion to which the rear bow metal (6) can be attached when the case is reversed from front to back.
上記実施例においては、樹脂製受網について例示したが
、パンチングメタル等の打ち抜き受網でも良い。In the above-mentioned embodiment, a resin-made receiving net is exemplified, but a punched receiving net made of punched metal or the like may be used.
