Abstract

(57) [Summary] (Modified) [Purpose] To prevent the deformation of both sides of the rubber crawler and to prevent mud gathering and slipping on both sides of the wetland so that it can exert its power in running in the wetland. [Structure] Core bars (2) are embedded at regular intervals in an endless belt-shaped rubber body (1) having a lug (1a) formed on the outer peripheral surface side, and a reinforcing wire is provided along the outer peripheral side of the core bar (2). In the rubber crawler in which the strip (3) is embedded, the lug (1a) is provided with a protrusion (1b) projecting downward from portions corresponding to both ends (2a) of the cored bar (2).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rubber crawler used for a traveling device of a combine.

[0002]

[Prior Art]

 Conventionally, in the rubber crawler used for the combine, as shown in "Fig. 4", the strength of both sides outside the core metal is insufficient, and in the case of traveling in a wetland, the direction is as shown by the arrow (a). It curves and becomes a dish shape. By transforming into this dish shape, the mud moves like the arrow (b) and rises, U-turns the aircraft and returns to the next step, the cutting blade scoops the mud and The mud adheres to the root of the plant and is supplied to the threshing section while hindering the transportation, and the threshing process also becomes unpredictable. In addition, since both sides are curved and dish-shaped, the traction force is lost and slippage occurs, which makes traveling difficult. In addition, (C) shows the planted culm.

[0003]

[Problems to be solved by the device]

 As described above, the conventional rubber crawler has the problems described in the previous section when running in a wetland. Therefore, the present invention prevents deformation of both sides to prevent mud and slip on both sides in a wetland. It provides a rubber crawler that is effective for running in wetlands where the occurrence of

[0004]

[Means for Solving the Problems]

 Therefore, in order to provide the above-mentioned rubber crawler, the present invention embeds metal cores at regular intervals in an endless belt-shaped rubber body having a lug formed on the outer peripheral surface side, and along the outer peripheral side of the metal core. In the rubber crawler in which the reinforcing wire is embedded, the lug is provided with a protrusion protruding downward from portions corresponding to both ends of the cored bar.

[0005]

[Action]

 As a result, the strength of both sides of the rubber crawler increases, it does not deform even when running in a wetland unlike the conventional one, and the projection suppresses the mud that is trying to move outward, so the mud gathers. It is possible to keep the amount of sinking to a minimum and to drive with good performance without causing slippage.

[0006]

【Example】

 Hereinafter, the rubber crawler according to the present invention will be described with reference to an example of the one used as a traveling device of a combine, and this combine is mounted on a traveling device (a) composed of a rubber crawler as shown in FIG. The threshing section (A) is installed on the left side of the installed machine stand (4), and the grain storage, which is a grain tank that stores the grains selected by the threshing section (A) and wind-selected Part (G) and engine (E) for driving are mounted front and back, and a control part (C) is provided in front of the grain accommodating part (G), and the control part is provided from the front side of the threshing part (A). The reaping unit (B) is arranged toward the front side of (C), and the planted culm is cut and struck with the forward movement of the aircraft, and the grains are stored in the grain storage unit (G). Straws fell to the rear of the machine and the grains stored in the grain container (G) were fried by the fried cylinder (5). It has been discharged Oh - adapted to be removed to a suitable place inherited by gas (6).

Next, the main part of the rubber crawler of the present invention will be described with reference to FIGS. 1 and 2, and this rubber crawler has a lug (1a) formed on the outer peripheral surface side. The cored bar (2) is embedded in the endless belt-shaped rubber body (1) at regular intervals, and the reinforcing wire (3) made of wire is embedded along the outer peripheral side of the embedded cored bar (2). It consists of a front sprocket (9) pivotally mounted on a drive shaft (8) projecting outward from the mission case (7), several wheels (10) and a rear side. It is hung around the tension wheel (11) and the outer peripheral surface serves as a grounding surface for running the aircraft.

Then, the lug (1a) extends downward from the reference ground contact surface (d) from a portion slightly inward from both side ends (2a) of the core metal (2) to an outer end of the lug (1a). The protruding portion (1b) is integrally molded, and the protruding portion (1b) has an inverted triangular shape as shown in FIG. 1, and the outer end surface (12) has an inclined surface as shown in FIG. In addition, the front side surface (13) and the rear side surface (14) are also formed as slopes connected to the lug (1a) portion on the side forming the reference ground contact surface (d).

The rolling wheel (10) rotates while stepping on the inner peripheral surface of the endless belt-shaped rubber body (1) while straddling the two rows of the detachment preventing projections (15), and the front and rear core bars ( A hole (16) into which the sprocket (9) meshes is provided at a position corresponding to between the disengagement preventing projections (15) between the two.

As a result, the rubber crawler has a portion extending from a portion slightly inward from both side ends (2a) of the core bar (2) to an outer end of the lug (1a), that is, both sides of the core bar (2). The strength of the part increases, and even when running in a wetland, it does not bend and deform upward, and the protrusion (1b) suppresses the mud that is trying to move outward, and prevents the mud from coming outward. The amount of subsidence is minimized, and the car can run with good performance without causing slippage.

[0011]

[Effect of the device]

 As described above in detail, the rubber crawler according to the present invention has cored bars (2) embedded at regular intervals in an endless belt-shaped rubber body (1) having lugs (1a) formed on the outer peripheral surface side thereof. In a rubber crawler in which a reinforcing filament (3) is embedded along the outer peripheral side of (2), the lug (1a) is projected downward from portions corresponding to both ends (2a) of the core metal (2). Since it is characterized by having a protruding portion (1b), the strength of both sides of the rubber crawler increases, and it does not deform like the conventional one even when running in a wetland, In addition, since the protrusion (1b) suppresses the mud that is trying to move outwards, mud is eliminated and the amount of subsidence is minimized, and slippage does not occur and performance is excellent and it is effective for running in wetlands. It became a thing.
