Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は主として湿田で使用される農機用のクローラ
走行装置に係り、詳しくは、クローラベルト内の排土機
能を備えたものの改良に関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a crawler traveling device for an agricultural machine mainly used in wetlands, and more particularly to an improvement of a crawler belt having a soil discharging function.
従来、排土機能を備えたクローラ走行装置としては、
例えば特開昭64-41483号公報に示されるものがあった。Conventionally, as a crawler traveling device having a soil discharging function,
For example, there is one disclosed in JP-A-64-41483.
すなわち、クローラベルトのループ内の後部でテンシ
ョン輪の横側に位置する箇所に、排土用の円盤スクレー
パを傾斜姿勢で設けると共に、前記クローラテンション
輪で前記円盤スクレーパを回転駆動するように構成し、
クローラベルトの内周面に載って後方に移送されてくれ
る土を、傾斜姿勢で回転する円盤スクレーパで掻き寄せ
てクローラベルトの横外側に排出するようになっている
のである。That is, a disk scraper for earth removal is provided in a tilted position at a position located on the side of the tension wheel in the rear part of the crawler belt loop, and the crawler tension wheel is configured to rotate and drive the disk scraper. ,
The soil that is placed on the inner peripheral surface of the crawler belt and transported to the rear is scraped by a disk scraper that rotates in an inclined posture and discharged to the lateral outside of the crawler belt.
従来の上記排土手段においては、クローラベルトの内
周面側からの排土を円滑、かつ、確実に行うことができ

て取付ける機構や、テンション輪と前記円盤スクレーパ
とを連動連結する機構が必要で、構造が複雑でコスト高
につくものであり、この点に実用上に難点があった。In the conventional soil discharging means, soil can be smoothly and surely discharged from the inner peripheral surface side of the crawler belt, but a mechanism for mounting the scraper in an inclined posture and a tensioner A mechanism for interlocking the wheel and the disc scraper is required, and the structure is complicated and the cost is high, which is a practical problem.
本考案は、クローラベルトの内周面側からの排土を確
実にできうる走行装置を構造簡単なものとして提供する
ことにある。An object of the present invention is to provide a traveling device having a simple structure that can surely remove soil from the inner peripheral surface side of the crawler belt.
本考案による農機用クローラ走行装置が特徴構成とす
るところは、クローラベルトのループ内の後部に備えら
れたテンション輪の外側部に該テンション輪よりやや小
径の弾性筒を、その弾性復元力がテンション輪の外側部
で筒半径方向外方側へ作用するように、筒軸線方向での
一端側を支持する状態で取り付けてあることにあり、そ
の作用及び効果は次のとおりである。The characteristic feature of the crawler traveling device for agricultural machines according to the present invention is that an elastic cylinder having a diameter slightly smaller than the tension wheel is provided on the outer side of the tension wheel provided at the rear part of the loop of the crawler belt. The outer side portion of the ring is attached in a state of supporting one end side in the cylinder axis direction so as to act outward in the cylinder radial direction, and the operation and effect are as follows.
湿田走行を行うと、クローラ走行装置の沈下に伴って
クローラベルト内に泥土が入り込みクローラベルトの内
周面に載って後方に移送されてくる間に塊状に成長す
る。そして、この土塊がテンション輪の外側部に取り付
けてある弾性筒とクローラベルトの隙間に持ち込まれる
ことによって土塊が圧縮され、土が柔らかい場合には土
塊は押し崩され、一部の土は外側方に押し出されるとと
もに、一部の土はクローラベルトの回動に伴って前記隙
間を通って持ち回され、テンション輪の前部付近に崩れ
落ちる。When traveling in a wetland, mud enters the crawler belt as the crawler traveling device sinks and grows in a lump while being carried on the inner peripheral surface of the crawler belt and being transferred rearward. When this soil mass is brought into the gap between the elastic cylinder attached to the outer side of the tension ring and the crawler belt, the soil mass is compressed, and when the soil is soft, the soil mass is pushed down and some soil is moved outward. While being pushed out, part of the soil is carried around through the gap with the rotation of the crawler belt and collapses near the front part of the tension wheel.
又、硬い土塊が前記隙間に持ち込まれた際には、弾性
筒が中心側に弾性変形され、傾斜変形した弾性筒外面に
よって土塊は横外方に押し出される。Also, when a hard soil mass is brought into the gap, the elastic cylinder is elastically deformed toward the center side, and the soil mass is pushed laterally outward by the outer surface of the elastic cylinder that is inclined and deformed.
以上説明したように、本考案によればテンション輪に
弾性筒を取付けるだけの極めて簡単、かつ、安価に製作
できる構造でありながら、大きい土塊に生成させること
なく外方に排出あるいは押し崩すことができ、実用上有
益である。As described above, according to the present invention, the elastic cylinder is attached to the tension ring, which is extremely simple and can be manufactured at low cost. It is possible and practically useful.
