Abstract

PURPOSE:To prevent a trouble from taking place, by forming ribs in the outside part of the inner peripheral surface of a track belt so that mud gripped by the track belt may be smoothly discharged outside of the track belt without the mud being massed into large blocks. CONSTITUTION:A belt body 1 made of resilient materials is formed into an endless shape. A plurality of ribs 2 are formed at equal intervals on the inner peripheral surfaces of both side sections 1b, 1b' which are laid both sies, in the widthwise direction W, of a middle section 1a along the longitudinal direction of the belt body. Further, engaging holes 3 for sprockets are formed in the middle section 1a of the belt body with orthogonal core metals 4 being embeded between these holes 3. When mud A is gripped in the belt body, the mud A is discharged outside ot the belt body under action of the ribs 2 before the mud A is massed into a large block.

Description

[Detailed Description of the Invention] [Technical Field] The present invention is applied to an agricultural combine harvester, etc., which is stretched between a driving wheel and an idler wheel of a vehicle body, and in which a water aquifer is made of an elastic material and is formed into an endless shape. This study concerns an elastic endless track belt.

(Prior Art) A conventional elastic endless track belt, for example, that of an agricultural combine harvester, is stretched between a driving wheel 11 and an idler wheel 12, as shown in FIGS. This orbital belt 100
Generally, the rolling wheels 13 come into contact with each other. When such a track belt 100 is run in a soft field, mud A is trapped mainly on the inner peripheral surface of the track belt 100 when turning (
(See Figure 1(a), state immediately after turning), the trapped mud becomes a lump as shown in Figure 1(b), and is then discharged.

Therefore, when used for rice harvesting, as shown in FIG. 2, the track belt 100 on the left side with respect to the advancing direction of the combine (arrow direction in the figure) runs in contact with the unharvested rice B, and the track belt 100 Mud Δ accumulated in large lumps inside
As shown in Fig. 3, uncut rice B is removed while the combine harvester is running.
(In some cases, it may even knock down the uncut f, 71 B). In this way, mud A is placed at the base of unharvested rice B.
When the clump of mud A is dropped, the combine harvester picks up the clump of mud A and the rice together when harvesting the rice in the next row (on the left), and during the transportation process,
Mud A was clogging during the threshing process, causing trouble. In addition, what is indicated by the reference numeral 10 in FIG. 3 is the vehicle main body of the combine harvester.

〔the purpose〕

This invention was invented to solve the above-mentioned problem, and eliminates the cause of the conventional trouble by discharging the mud trapped by the track belt in relatively small lumps instead of turning it into large lumps. The purpose of this invention is to provide an elastic endless track belt that eliminates the above problems.

〔composition〕

In order to achieve the above object, the present invention provides a fabric body with a large number of ribs arranged at regular intervals on at least the inner peripheral surface of the outside of the vehicle body in both outer parts located on both sides in the width direction of the center part of the cloth body in the longitudinal direction of the cloth body. These ribs are formed by slanting them so that the outer ends of the ribs are located at the rear with respect to the direction of movement of the cloth body, and the inner ends of the ribs are located at the front.1. Ta.

〔Example〕

Preferred embodiments of the present invention will be described below with reference to the drawings below.
