Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a work vehicle for removing ice burns on roads.

[Conventional technology]

If snow accumulates in a short period of time without being removed in time, and a truck with a loaded platform passes over the snow, the snow is likely to become compacted and cause ice burns. Once ice burns form, they harden and condense on the road surface, making it impossible for normal snow removal vehicles such as plows to remove the snow.

Therefore, in the past, ice burns were removed using a truck grader or the like. However, conventional graders have the drawback of not being able to handle ice burns formed in depressions on the road surface, such as ruts, which has been considered a major problem. This is because both ice burns and ruts are caused by a large number of vehicles traveling along the same wheel trajectory, so they tend to form in the same location.

〔Problems to be solved〕

This invention was developed in view of the above-mentioned problems with ice burn treatment using conventional graders. This is a subject to be addressed.

[Means for solving problems]

Therefore, in the present invention, the snow compaction excavator, in which the row incisors are biased downward, is placed near the front of the work vehicle, and the first edge made of an elastic plate is connected to the elastic wire rod arranged densely in a brush-like manner. By placing a composite plow with two overlapping second edges on the front and back of the work vehicle so that they can be pressed against the road, ice burn can be removed even from concave parts of the road surface. be.

〔Example〕

Hereinafter, the present invention will be explained based on examples.

A snow compaction excavator 2 and a composite plow 6 are vertically installed at the bottom of the truck 1. These are pressed against the road surface with appropriate contact pressure when a hydraulic cylinder is activated by an operator's operation. When the truck 1 runs, the snow compaction excavator 2 cuts through the ice burn, extremely reducing the adhesion of the ice burn to the road surface, and then the composite plow 6 cuts the ice burn into strips onto the road. Since it is removed laterally, ice burn treatment is possible.

To explain in more detail below, snow compaction excavator 2
are a support frame 3, a horizontal U-shaped elastic support member 4,
The row cutting teeth 5, 5, ... are vertically installed through the ice burners 4, . tooth 5,
5,... will be biased downward and will bite into the ice burn. If the pressing force of the snow compaction excavator 2 is selected appropriately, the row incisors 5, 5,...
It only bites into ice burns and does not damage the road surface. When the truck 1 is run in this state, the row incisors 5, 5, . . . cut into the ice burn, forming grooves and tearing it into strips, sometimes causing it to turn into blocks of ice. At this time, even if the road surface is uneven, the row incisors 5,
5, ... elastically moves up and down to follow the road surface.

Further, in this embodiment, the composite plow 6 is
The first edge 10 and the second edge 9 are stacked one on top of the other, and are arranged at the bottom of the track 1.

Specifically, the first edge is a rubber plate that maintains its elasticity even at low temperatures, the second edge is a flat bundle of steel wire, and the whole is placed on a bracket with the steel wire bundle superimposed on the back of the elastic plate. It is fixed at the bottom of the truck 1. When the truck 1 runs with both edges of the composite plow 6 in pressure contact with the road, the composite plow 6 removes the band-shaped ice burn produced by the snow excavator 2 laterally.

At this time, since both edges of the composite plow 6 have elasticity, they remove snow while following the unevenness of the road surface.

Due to the difference between plate material and wire material, the first edge
Edge has more elasticity. However, even if an attempt is made to remove ice burns using only the edge of a steel wire, the tip of the steel wire tends to succumb to the drag of the ice burn, resulting in very poor removal efficiency. For this reason, a rubber elastic plate material is used as the first edge to remove the ice burn in the first stage, and in the second stage, a steel wire bundle is removed in the recesses where the edge could not be traced in the first stage. Perform removal work using an edge. This combined work makes it possible to ideally remove ice burns.

In this embodiment, the edges of the composite plow 6 are cut into the road surface at a negative cutting angle. This is to improve the ability of the edge to follow unevenness. Furthermore, the reason why the second edge is arranged immediately behind the first edge is to support the rubber plate with the steel wire.

[Effect of idea]

As described above, the ice burn treatment vehicle of the present invention is capable of ideally removing ice burns while dealing with uneven road surfaces through the combined action of a snow compaction excavator and a compound plow. Highly useful.
