[0002]

2. Description of the Related Art Conventionally, a crusher (breaker) for crushing asphalt or rock used at a construction site or the like by vibrating or expanding and contracting a crushing rod at the tip thereof has been known. Breakers are used by humans or attached to excavator tips.

[0003] The asphalt surface partially broken in this way is peeled off by a bucket 62 of a shovel shown by reference numeral 60 in FIG. The asphalt piece 63 excavated in this way is lifted by the single arm 61 and is loaded on a dump truck or the like by a turning operation or an arm operation.

[0004] On the other hand, in recent years, a road construction vehicle has been known which automatically peels off asphalt on a road surface or the like and paving at the same time.

Among them, a peeling vehicle as shown in FIG. 8 is conceivable. That is, in FIG. 8, reference numeral 75 denotes a front cutting portion provided on a substantially asphalt surface with a front end directed downward at the front. Reference numeral 84 denotes a transport conveyor that receives the asphalt peeled off at the rear and transports the asphalt to the rear. Further, reference numeral 73 denotes asphalt, 74 denotes a caterpillar, 83 denotes a drive engine, and 82 denotes a travel control controller.

[0006] Therefore, the asphalt 73 peeled off by the front cutting section 75 is pushed up by the vehicle propulsion force, and is conveyed by the conveyor 8.
The asphalt peeling operation is carried out with the configuration for discharging backward in 4.

[0007]

In the above-mentioned conventional construction, there is a problem in the asphalt peeling work after a part of the asphalt has been shaved by a breaker or the like, and a complicated work with low efficiency is required for the treatment. Automation and speedy stripping work were difficult.

[0008] That is, asphalt pieces shaved off by a bulldozer or excavator remain in the bucket, and therefore, the work must be performed by removing the asphalt piece from the bucket according to the capacity of the bucket. There is a problem that the asphalt peeled must be treated by operating a complicated arm constituted by the indirect link.

As described above, in asphalt stripping where the construction point changes every moment, complicated arm operation and the like hinder automation of unmanned running and the like.

On the other hand, a road construction vehicle that automatically separates asphalt on a road surface and performs pavement at the same time is effective for pavement construction on a highway and the like, but is effective for gas pipes and water pipes in towns and cities. It was not suitable for asphalt peeling work for local construction of.

[0011] That is, it is good for the purpose of automatically paving asphalt on one side of the road immediately after the asphalt is peeled off, but is not suitable for paving through a single work after peeling off only a part of the asphalt of the road surface. In addition to the large size and the high cost, the operation of stripping a line having a width of 1 m, for example, is difficult due to its configuration.

[0012] Therefore, what is desired is a device which can be easily used in an urban area or the like with a simple configuration and which can peel off asphalt in a line with a limited width.

On the other hand, in the case of the present application, asphalt shaved with a quick and simple movement is efficiently processed, as shown in FIG.
Considering the peeling vehicle shown in 71, the peeling width is difficult to adjust, and the end face side remains in the peeled state,
There is a problem that the peeling width is not uniform and the cut surface is distorted.

[0014] Therefore, what is desired is one that can cleanly separate a cut surface with a predetermined peeling width and that can perform work with a quick and simple movement.

It is an object of the present invention to provide a peeling apparatus which peels off a cut surface neatly in a asphalt peeling operation at a predetermined peeling width and cleanly cuts the asphalt work quickly and efficiently.

[0016]
