For this purpose, it is necessary to remove the crawler from a drive wheel called an idle roller by using a burl or the like. However, it was difficult to remove the flora because the raised portion inside the flora meshed with the idle roller. Also, the mounting after removing it on the contrary was difficult because the convex portion did not easily mesh with the idle roller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A detachable tool A of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of the tool A and FIG.
-X sectional drawing is shown. FIG. 3 is a side view. In the figure, (1) is a substrate, and this substrate (1) is curved so as to match the arc curve of the idle roller (11) with reference to FIG. And three window holes (2-1) are formed in the center of the curved bottom part of this substrate (1).
(2-2) and (2-3) are provided. This window hole is for fitting the raised portion (12) on the inner surface of the crawler (10), whereby the tool A is fed as the idle roller (11) rotates. (3) and (4) are opposite 2
It is provided by sandwiching the central window hole (2-2) with a strip guide plate, and the guide plates (3) and (4) are installed upright at an angle α as shown in FIG. As shown in the drawing, they are curved outwardly, and as shown in FIG. 3, the rising angles with respect to the height h are opposite to each other. FIG. 4 is a diagram showing an embodiment, and shows a part of a drive unit of the combine, (10) shows a crawler which is an endless track, and (11) shows an idle roller which is a drive wheel. (12) is a raised portion provided inside the idle roller, and the raised portion (12) meshes with the idle roller (11) so that the combine travels. (1
Reference numerals 3) and (14) denote track rollers that are auxiliary wheels. Further, (15) is a tension bolt for adjusting the tension of the crawler (10). Next, the mode of use of the crawler attachment / detachment tool A of the present invention will be described. The tool A is an idle roller by fitting two of the three window holes at the bottom of the tool A into the protrusions (12) inside the crawler. At (11), the crawler (10) is pressed to be in a fixed state. The guide plates (3) and (4) of the tool A guide the idle roller to the outside or inside of the raised portion (12) of the crawler according to the rotation of the idle roller (11) to facilitate the attachment / detachment. Guide plates (3), (4)
Idle roller (1
1) is prevented from riding on the tool A and is slid inward (guide side) so that it can be more easily guided in the detaching direction. The guide plate only works on one side at the time of attachment / detachment. By raising the rotation direction and the rear part of the plate, the idle roller is guided so as to surely get over the protrusion. Also, by changing the combination of three window holes, 1
Although it is possible to attach and detach the crawlers on both the left and right sides with one tool,
By pairing the inner guide plates with those with opposite angles, the left and right crawlers can be attached and detached more safely simply by always setting them on the lower side of the crawlers.

【発明の効果】本発明のクローラ脱着工具Aは前述の如
き構成であるため、単にクローラとアイドルローラの間
に噛み合せて僅かにアイドルローラを回転させるのみで
簡単にクローラをアイドルローラから外すことができる
ため、コンバインの足廻りの整備および補修が楽に行え

である。またこの操作は本発明の脱着工具を2個使用す
ることによって左右2条のクローラを同時行える。
Since the crawler attaching / detaching tool A of the present invention has the above-described structure, the crawler can be easily removed from the idle roller by simply engaging the crawler and the idle roller and rotating the idle roller slightly. As a result, it is possible to easily carry out the maintenance and repair of the underbody of the combine, which is an effect that has not been heretofore considered. Further, this operation can be performed simultaneously by using the two detachable tools of the present invention for two right and left crawler crawlers.
