Description

[Detailed description of the invention] [Industrial field of application] The present invention has one end fixed to a truck frame on the front side of the wheel at the rear end, which is equipped with a rubber crawler belt wrapped around it, and the other end fixed to the truck frame. This invention relates to a crawler traveling device for a reaping harvester, which is equipped with a cantilevered clod-breaking bar extending toward the rear end through the outside of the rear wheel.

[Prior Art] In the crawler traveling device of such a reaping/harvesting machine, mud adhering to the inner periphery of the crawler belt is moved outward in the winding direction of the belt with little escape displacement, and the peeled mud is returned onto the belt. Conventionally, as shown in FIG. 4, the clod breaking rod 6 is placed at a position as low as possible relative to the ground in order to enhance its soil clod breaking action. I was trying to install it.

[Problem that the invention attempts to solve]

At the installation position of the clod breaking rod 6, the upward curling locus a of the outer edge of the crawler belt 5 interferes with the outer end of the clod breaking rod 6, so each time the outer edge of the crawler belt 5 turns up, the crawler belt 5 comes into contact with the corner of the outer end of the clod breaking rod 6 and damages the crawler belt 5, resulting in early damage to the crawler belt 5.

By the way, the core metal 7 is attached to the rubber crawler belt 5.
Since the crawler belt 5 is not buried over its entire width, the outer end of the crawler belt 5 may curl up when the aircraft travels over uneven fields or the like.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to suppress damage to the crawler belt due to the curling up of the outer edge of the crawler belt.

[Means for solving problems]

The characteristic configuration of the present invention is that the outer end of the clod breaking bar is provided in such a way that it does not protrude beyond the outer edge of the crawler belt, and the interference position between the curling up trajectory of the outer edge of the crawler belt and the clod breaking bar is The installation height of the soil clod breaking rod is set so that it is located slightly inward from the outer end of the soil clod breaking rod, and its functions and effects are as follows.

[Effect]

According to the above configuration, since the outer end of the clod-breaking bar does not protrude outward beyond the outer edge of the crawler belt, the clod-breaking bar is prevented from being deformed or damaged by contact with other objects while traveling. This makes it possible to maintain the position of the clod breaking bar in the set state, and even if the outer edge of the crawler belt rolls up and comes into contact with the clod breaking bar.
The outer edge of the belt simply slides into contact with the outer circumferential surface of the clod breaking rod near the outer end, and no large scratches occur.

[Effect of idea]

In other words, in this invention, rather than avoiding contact between the outer edge of the crawler belt and the clod-breaking rod, the mounting height of the clod-breaking rod is set so that they come into contact in a sliding state that does not cause major damage. By arranging the clod-breaking rod so that its outer end does not protrude beyond the outer edge of the crawler belt, the clod-breaking rod can be maintained in a state where it can effectively perform its function, while also improving the crawler belt. Now we can control the damage.

[Example] As shown in FIG. 3, a crawler traveling device installed in an agricultural vehicle such as a combine harvester is configured by:
A drive wheel body 2 and a crawler tensioning wheel body 3 are provided at both front and rear ends of the left and right pair of track frames 1, 1, and a guide wheel body 4 is provided between the wheels 2, 3.
At the same time, a rubber crawler belt 5 is wound around the wheels 2, 3, 4, and so on.
A large number of core metals 7 protruding inward from the belt 5 are embedded at equal intervals in the belt longitudinal direction.

As shown in FIG.
A clod breaking rod 6 is attached in a cantilevered manner extending rearward and outward from a location near the rear end to a position corresponding to the outer edge of the crawler belt.
The soil clods generated within the winding loop are broken up and removed laterally and outwardly.

As shown in FIG. 1, the clod breaking bar is set so that the curling trajectory a of the outer edge of the crawler belt 5 interferes with the clod breaking bar 6 at a location slightly inward from the outer end of the clod breaking bar 6. The installation height of 6 is set to prevent the crawler belt 5 from coming into contact with the corner of the outer end of the clod breaking rod 6 due to the outer edge of the crawler belt 5 turning up.
