Abstract

PROBLEM TO BE SOLVED: To speedily and certainly collect crushed waste materials on a road surface by feeding them to an accumulation box by a cross feeding device and delivering left-over small waste materials to the cross feeding device by a rotary brush and high pressure injection air. SOLUTION: A working machine 3 is constituted of a machine frame connected to a rear part connector 25 of a tractor 1 and long in the cross direction of a road, a cross feeding device 17, a rotary brush 19, a plurality of injection nozzles 21 and an accumulation box 23. At the time of working, the cross feeding device 17 feeds crushed waste materials to the inside of the accumulation box 23 and pushes them out to a collection device 37 by air pressure from a compressor 11. At this time, as cross feeding speed of the cross feeding device 17 increases as it approaches the box 23, residence of the waste materials in the box 23 does not occur. Remaining small waste materials are blown off toward the rotary brush 19 by injection pressure of the injection nozzle 21 and delivered to the cross feeding device 17 by the rotary brush 19. Consequently, it is possible to certainly collect the waste materials by one work without leaving the left-over.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road surface crushed waste material recovery device for recovering crushed waste material generated when crushed on a road surface during repair.

[0002]

2. Description of the Related Art Conventionally, as a first work for repairing a concrete board, for example, on an airport runway or the like, the surface of a damaged road surface is crushed by high-pressure water by a water jet or the like. The crushed waste materials, etc.
As a second work, the work is collected by a work machine such as a load sweeper.

[0003]

The crushed waste material and the like are collected by a working machine such as a road sweeper. In particular, a road surface crushed by high-pressure water by a water jet or the like has a small depression. At present, it is difficult to reliably collect crushed waste materials and the like that have been crushed into small pieces because they have irregularities, because the crushed waste materials and the like fall into the grooves.

[0004] For this reason, the work is repeatedly performed, or the portion where the leftover occurs is manually performed. For example, as in an airport runway,
If the repair location is wide and long, a large amount of time and labor is required, which is not desirable in terms of workability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a road surface crushed waste material collecting apparatus capable of reliably and promptly completing the operation of collecting crushed waste materials and the like.

[0006]

In order to achieve the above object, the present invention firstly provides an accumulation box supported by a fuselage, and an intake opening supported by the fuselage along the width direction of a road. A traverse device that is disposed in a cover case having a front side and laterally feeds crushed waste materials and the like along the cover case into the accumulation box, and a brush portion disposed in the cover case behind the traverse device. It comprises a rotating brush having substantially the same length as the traverse device acting on the road surface, and a plurality of spray nozzles arranged behind the cover case and spraying toward the road surface into the cover case.

Secondly, a stacking box supported by the fuselage and a guide case supported by the fuselage along the width direction of the road and having an intake opening opening rearward in the traveling direction are arranged in a guide case, and crushed waste materials, etc. And a plurality of injection nozzles that are disposed behind the intake opening of the guide case and feed crushed waste materials and the like to the intake opening by the injection pressure. It is composed of

[0008] In a preferred embodiment, the traverse device is formed in a spiral shape, and the feed pitch of the spiral is gradually increased toward the accumulation box so that the feed speed is gradually increased.

Alternatively, the plurality of injection nozzles can swing back and forth, left and right.

Alternatively, the injection of the injection nozzle is air or water or a combination of air and water.

In such a road surface crushed waste material recovery apparatus,
In the first embodiment, the crushed waste material on the road surface crushed by the crushing means is traversed by the traverse device and fed into the accumulation box. At this time, the feed speed by the traverse device gradually increases as approaching the accumulation box, so that no stagnation occurs at the accumulation box,
A smooth feeding state is ensured.

On the other hand, small crushed waste materials left by the traversing device are sent out to the traversing device by the action of the brush portion of the rotating brush acting on the road surface. At the same time, the injection pressure applied from the plurality of injection nozzles toward the road surface into the cover case acts. At this time, since the high-pressure air is ejected from the ejection nozzle while swinging back and forth, and left and right, the leftover does not occur in one operation, and the air is reliably collected.

In the second embodiment, the crushed waste material on the road surface crushed by the crushing means is directed toward the intake opening of the guide case by the injection pressure injected from the plurality of injection nozzles. And blow it off. This is a so-called broom-dust removal relationship in which the dust removal is moved backward and fed by a broom. In this case, the injection nozzle injects while swinging back and forth, left and right,
Even in the case of small crushed waste materials, there is no leftover and they are collected in one operation.

On the other hand, the crushed waste material and the like sent into the intake opening are traversed by the traverse device, and are smoothly fed without staying in the accumulation box.

Further, according to the present invention, an airframe movable along the longitudinal direction of the road, and a work supported by the airframe and capable of reciprocating in the width direction of the road orthogonally to the traveling direction of the airframe. A machine main body, a traverse device that is supported by the work machine main body and traverses along the traveling direction of the machine toward the suction port, and is disposed behind the traverse device, and the brush portion acts on a road surface. It comprises a rotating brush having substantially the same length as the traversing device, and a plurality of spray nozzles arranged behind the rotating brush and spraying toward a brush portion of the rotating brush acting on a road surface.

The spray nozzle has a first spray nozzle for spraying water and a second spray nozzle for spraying air behind the first spray nozzle.
The structure consists of a combination of the injection nozzles.

Therefore, according to this embodiment, the work is performed while repeating the operation of reciprocating the work implement body along the width direction of the road while moving the machine body along the longitudinal direction of the road.

During this operation, the crushed waste material and the like are traversed by the traverse device along the traveling direction of the machine body and sent out to the suction port. At the same time, the crushed waste material and the like are sent out to the lateral feeder by the brush portion of the rotating brush acting on the road surface. At the time of rotation of the rotating brush, water is sprayed from the first spray nozzle onto the road surface, and subsequently air is sprayed from the second spray nozzle, and enters into the concave portion of the road surface due to the interaction between water and air. Even the small crushed waste material is surely scraped out by the brush portion and sent out to the lateral feeder for recovery work.

In this case, since the work proceeds in the width direction of the road with respect to the traveling direction of the machine, the size of the machine can be reduced, and the maintenance, management and maintenance of the machine can be facilitated. .
