In the case of an icy surface, not only does the crawler slip and hinders running, but also the crawler may skid and pose a danger to running. In particular, in snow removal work on slopes such as ski slopes, the crawler slips frequently, and the work efficiency may be significantly reduced or the work may not be possible.

Accordingly, the present invention is directed to a traveling work vehicle provided with a rubber crawler traveling device, which can prevent a crawler from slipping or skidding on a slippery traveling surface such as a snow surface or an icy surface, thereby achieving good work. It is an object of the present invention to provide a non-slip device for a traveling work vehicle, which can ensure safety and prevent danger during traveling.

[0005]

In order to achieve the above object, a non-slip device for a traveling work vehicle according to the present invention relates to a traveling work vehicle equipped with a rubber crawler traveling device. And a non-slip chain wound around the running surface.

In the present invention, the rubber crawler has a groove in the rotation direction on the outer periphery thereof, and the anti-slip chain is wound around the groove of the rubber crawler so that a part thereof is buried. Is preferred.

In the present invention, the anti-slip chain has a length substantially the same as the entire length of the anti-slip chain winding portion of the rubber crawler, and is provided with engaging mechanisms which can be disengaged from each other at both ends. Is preferred.

Further, in the present invention, it is preferable that the non-slip chain includes a large number of non-slip reinforcing portions in a portion wound around the rubber track.

In FIG. 1, reference numeral 1 denotes a traveling work vehicle, and a mowing machine 2 is mounted on a front portion of the traveling work vehicle 1 by a work machine mounting mechanism 3 so as to be adjustable up and down and detachably. A driver's cab 4 is located on one side of the front of the traveling work vehicle 1.
However, a motor room 5 is provided at the rear. 6 is a rubber crawler traveling device, 7 is a rubber crawler, 8 is a sprocket, 9 is an idler, and 10 is a track roller.

The rubber track 7 of the rubber track traveling device 6
As shown in FIG. 2, the outer circumference of the
1 is provided, and a non-slip chain 12 is wound around the concave groove 11. The non-slip chain 12 wound around the concave groove 11 has a part buried in the concave groove 11 and a part bulging from the outer peripheral surface of the rubber crawler 7. The non-slip chain 12 is provided with a large number of non-slip reinforcing portions 13 at the winding portion around the rubber crawler 7.
As shown in FIG. 3, the non-slip reinforcing portion 13 is formed by alternately extending a chain into an annular shape on both sides, or alternately extending a branch-like chain (not shown) on both sides. Any structure may be used as long as it has a non-slip member that floats on the main chain, and the configuration is appropriate.

The anti-slip chain 12 is a rubber crawler 7
Is approximately the same length as the entire length of the anti-slip chain winding part,
As shown in FIG. 4, both ends of the non-slip chain 12 are provided with engagement mechanisms 14 that can be engaged and disengaged from each other. That is,
As shown in FIG. 4, one end of the non-slip chain 12 is a hook 15 and the other end is a hook ring 16.
Is detachable from the hanging ring portion 16. Non-slip chain 1
4, a plurality of hook rings 16 are formed in a chain, as shown in FIG. 4, and the entire length of the non-slip chain 12 including the portion of the hook ring 16 is the entire length of the anti-slip chain winding portion of the rubber track 7 If you make it a little longer, rubber crawler 7
Even when the length of the anti-slip chain 12 is greatly increased by use, the winding length of the non-slip chain 12 can be adjusted by appropriately selecting the hook ring 16 with which the hook 15 is engaged.

FIG. 1 shows a traveling work vehicle 1 equipped with a mowing machine 2.
FIG. 5 illustrates an example in which the snow removal work machine 17 is mounted on the traveling work vehicle 1. The snow removing work machine 17 shown in FIG. 5 is a snow blower,
Numeral 18 is the snow discharge tube.

The rubber track 7 of the rubber track traveling device 6
In order to attach the non-slip chain 12 to the rubber crawler traveling device 6 with a jack or the like, the anti-slip chain 12 is wound around the rubber crawler 7 in the concave groove 11, and the hook 15 at one end is connected to the other end. With the hooking ring portion 16. Further, as another mounting means, the non-slip chain 12 is stretched in a straight line on a flat place, and the traveling work vehicle 1 is slowly moved forward or backward, so that the rubber track 7 is put on the non-slip chain 12. Try to get on. Then, both ends of the non-slip chain 12 are turned to the upper side of the rubber track 7 and a hook 15 at one end is formed.
Is engaged with the hook ring 16 at the other end. In addition, according to this mounting means, since it is not necessary to lift the traveling work vehicle 1, the mounting of the non-slip chain 12 is easy.

The anti-slip chain 12 attached to the rubber track 7 can be removed by lifting the rubber crawler traveling device 6 using a jack or the like. 16, and the traveling work vehicle 1 can be easily removed by slowly moving forward or backward.

In the anti-slip device according to the present invention, the anti-slip chain 12 is wound and mounted so as to be partially buried in the concave groove 11 of the rubber crawler 7, so that it does not come off during running, and in particular, does not slip. Even if a strong stress is applied in the direction, there is no possibility that the non-slip chain 12 will come off.

In the anti-slip device according to the present invention, the anti-slip chain 12 may be entirely buried in the concave groove 11 of the rubber crawler 7. Can be expected.
In some cases, the anti-slip portion 13 may not necessarily be provided. In any case, road surface damage during traveling on the road can be prevented.

The length of the anti-slip chain 12 is substantially the same as the length of the anti-slip chain winding portion of the rubber crawler 7, that is, the entire length of the bottom surface of the concave groove 11 in the illustrated embodiment. Is engaged, the anti-slip chain 12 is firmly attached to the rubber track 7. If the anti-slip chain 12 is slightly shorter than the entire length of the bottom surface of the groove 11, the anti-slip chain 12 can be mounted more firmly by using the bending on the rubber track 7 side.

The anti-slip chain 12 is provided with a number of anti-slip reinforcements 13 at the winding portion around the rubber track 7, and when the rubber crawler traveling device 6 travels on the traveling surface, the anti-slip reinforcement 13 is applied to the traveling surface. It has a mode of contacting and biting in various states, so that it has a high anti-slip function especially when traveling on a snowy surface or an icy surface, and has an excellent anti-skid function during traveling.

[0020]

According to the present invention, in a traveling work vehicle equipped with a rubber crawler traveling device, the crawler can be prevented from slipping or skidding on a slippery traveling surface such as a snow surface or an icy surface. Thus, there can be obtained an effect that a high workability can be ensured and a danger during traveling can be prevented.
