BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled crushing and sieving apparatus for crushing and sieving waste such as concrete, wood, earth and sand and rocks generated at construction sites.

[0002]

2. Description of the Related Art In general, waste such as concrete, wood and earth and sand is generated at construction sites such as demolition and construction of buildings.
In recent years, the amount of such waste generated has increased, and it has become extremely difficult to secure an appropriate disposal site at hand. Therefore, the transportation cost to the disposal site increases, and the dump truck for transportation. Has hindered road traffic and caused illegal dumping, which is an obstacle to construction work.

Therefore, in order to reduce the amount of waste generated and protect the environment, the waste is crushed in the vicinity of the site, and a self-propelled type equipped with a crusher on a traveling carriage in order to reduce the volume and recycle the resources. Crushing device (see JP-A-5-31394).

[0004]

However, if the waste is crushed only by a crusher, the sizes of the waste become uneven,
It is difficult to recycle as a resource. On the other hand, a crusher and a sieving machine are provided on the traveling carriage to screen the crushed waste, and if the particle sizes are made uniform, it becomes easier to reuse as resources, but a crusher on one traveling carriage is used. When equipped with a sieving machine, the size of the machine becomes large, making it difficult to transport to the site by a trailer or the like, and it cannot be used at a narrow construction site.

The present invention solves such a problem of waste treatment, and can crush and screen the waste to facilitate recycling, so that the size of the machine does not increase and the site does not increase in size. It is an object of the present invention to provide a self-propelled crushing and sieving device that can be easily transported to and moved within a site, and can be used even in a narrow construction site.

[0006]

According to the present invention, a crushing vehicle having a crusher mounted on a traveling carriage, a sieving wheel having a sieving machine mounted on the traveling trolley, and the crushing machine and the sieving machine are connected to each other for crushing. The above problem is solved by constructing a self-propelled crushing and sieving device in combination with a conveyor for conveying objects. The conveyor, which is arranged outside the vehicle width of the traveling carriage, is pivotally attached to a support frame that is detachable from the traveling carriage.

[0007]

[Operation] When treating waste, stop the crushing wheel and the sieving wheel at the predetermined positions on the construction site, place the conveyor,
Supply waste to crusher. The waste crushed by the crusher is sent to the sieving machine by a conveyor and sieved, and the wastes classified by particle size are separately discharged and reused or disposed.

Since the crusher and the sieving machine are not mounted on one traveling trolley but separated into a crushing truck and a sieving truck, the traveling trolley can be a small one and can be used away from the construction site. When carrying a distance, by removing the conveyor so that the machine body is within the width of the traveling carriage, it can be easily carried by being loaded on a trailer or the like. It can be easily moved within the construction site by making the traveling carriage self-propelled.
