Abstract

PROBLEM TO BE SOLVED: To prevent earth and sand from being deposited on the frame of a crawler vehicle. SOLUTION: This crawler belt, which is formed by embedding metallic cores 8 engaged with respective teeth of a drive wheel in an endless rubber belt 7 wound around a running part, is provided with an earth removing plate 10 protrudingly-fitted at the right and left end parts on the rolling surface 9 side of the crawler belt 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crawler belt with an earth discharging device to be wound around a tracked vehicle including construction machines such as an all-terrain vehicle, a bulldozer, and a hydraulic excavator.

[0002]

2. Description of the Related Art In current tracked vehicles, upper and lower rolling wheels are mounted on a track frame provided between an idle wheel and a raceway wheel, and a rubber belt or iron crawler belt is wound around each of these wheels. It is common practice to drive the vehicle by rotating the rubber belt or iron crawler belt by the power transmitted to the starter wheels, but conventionally, when working on mud, etc., the dirt and sand that rides on the rolling surface side causes the belt or iron crawler belt to rotate. In order to prevent it from being rolled up and accumulated on the track frame, a plate is welded to the upper surface of the track frame to form a taper so that the upper surface of the track frame does not easily accumulate even when soil is applied.

[0003]

In the tracked vehicles centering around the above-mentioned conventional construction machines, the structure of the track frame is devised to prevent the accumulation of earth and sand, etc. When working in a quality area,
The adhesion of earth and sand is strong, and the earth and sand remain on the track frame only by changing the track frame structure. In such a case, if soil is left, it will dry if the temperature is high, and when it is cold, the water will solidify and the soil will become very hard.If it is a rubber crawler belt, the rolling surface side will rub and scratches or early wear will occur. Cause of.

For such highly viscous soil, it is not enough to change the structure of the truck frame as described above, and it is necessary to actively pulverize and discharge the soil. The present invention was developed to deal with such a problem, and an object thereof is to actively remove soil during traveling.

[0005]

The structure of the present invention for achieving the above object is a crawler belt in which an endless rubber belt wound around a running portion is embedded with a metal cored bar that meshes with each tooth of the starting wheel. Or, in a crawler belt in which a pair of left and right links are fastened with iron plates by bolts and adjacent links are endlessly joined by pins, an earth-discharging plate is provided at the left and right ends on the rolling surface side of the crawler belt. It is characterized by being projected.

Further, the earth discharging plate is provided so as to project at a point that divides the circumferential length of the belt into two or three equal parts.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will now be described with reference to the drawings, in which 1 indicates a traveling device, and a track frame 4 provided between an idler wheel 2 and a starting wheel 3 of the traveling device 1. The upper rolling wheel 5 and the lower rolling wheel 6 are attached to the endless rubber crawler belt 7 wound around these wheels, and the metal cored bar 8 meshing with each tooth of the starting wheel 3 is engaged as shown in FIG. The earth-discharging plate 10 was provided in a protruding manner at the left and right ends of the crawler belt 7 on the rolling surface 9 side. The earth removing plate 10 was fastened to the metal cored bar 8 at the point where the circumference of the belt is divided into two or three equal parts on the rolling surface side by bolts 11 as shown in FIG.

Thus, the rotation of the starter wheel 3 causes the crawler belt 7 to move in the direction of arrow A or B, and at the same time, the earth discharging plate 10 installed on the crawler belt 7 to move at the same time in the mud zone or the like. When traveling by the traveling device, the earth and sand that have entered from between the lower rolling wheels 6 ride on the rolling surface 9 of the crawler belt 7 and move in the moving direction B or C of the crawler belt 7. If the sediment continues to run on the truck frame 4 from the idler wheel 2 side or the starter wheel 3 side,
It is deposited, but when it reaches a certain height, the earth removal plate 1
Emitted by 0.

Since the earth unloading plate 10 has a considerable distance to the next earth unloading plate 10, even if the earth and sand adheres to the earth unloading plate 10 itself, it will drop during rotation and will not affect the performance. Although the soil discharging plate 10 can be used for a rubber crawler belt used in a place where soil quality is highly viscous, a high effect can be obtained, but it is not limited to this.

[0010]

As described above, according to the present invention, since the earth discharging plates are provided at the left and right ends of the crawler belt on the rolling surface side, the earth and sand accumulated on the track frame also rolls on the crawler belt. It is positively discharged by the earth-discharging plates protruding from the left and right ends of the surface side, facilitating cleaning and maintenance at the end of work and extending the life of machines such as upper wheels and using it for more expensive rubber crawlers In this case, it has an effect of preventing scratches and abrasion of the crawler.
