Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a recycling vehicle that crushes concrete, blocks, asphalt waste materials, and other materials to be processed that are generated at construction sites and the like to make them reusable products.

[0002]

[Prior art]

 A large amount of waste materials such as concrete, blocks, and asphalt are generated at construction sites such as the demolition and rebuilding of buildings and structures. These were once disposed of as waste, but in recent years it has become difficult to obtain a disposal site that can be disposed of, and even if a disposal site that can be disposed of is obtained, long-distance transportation is required.

Therefore, in order to crush such waste near the construction site and reuse the product as a foundation material for building structures, a roadbed material, a backfill material after excavation, etc. A movable recycling vehicle equipped with a crusher and a sieve has been developed. Such a recycling vehicle is provided with a hopper for inputting the processing target and a feeder for supplying the processing target input into the hopper to the crusher.

[0004]

[Problems to be solved by the device]

 However, since the plate feeder was used in the feeder of the recycling car to reduce the height of the entire device as much as possible, the entire amount of the processing object put in the hopper is supplied to the crusher regardless of its properties. It had been. Therefore, in conventional recycling vehicles, even fine particles such as soil and sand that do not need to be crushed contained in the material to be processed are supplied to the crusher. Finally, it was passed through the sieve into the product, and was then delivered from the unloading conveyor to the truck as a product.

Such a recycled product containing a large amount of fine particles such as earth and sand has an inadequate particle size distribution as a foundation material for building structures, a roadbed material, and a backfill material after excavation The price drops. In order to remove fine particles such as earth and sand from this product, it is necessary to install a sieve with a different mesh separately, which makes the entire device large. Also, if fine particles such as earth and sand that do not need to be crushed are supplied to the crusher, not only will the load on the entire device increase, but it will also adhere to the inside of the crusher and reduce crushing efficiency, It is not preferable because it adheres to the feed conveyor and the carrying capacity is reduced.

Further, in the plate feeder itself, fine particles such as earth and sand are likely to adhere to the plate due to its structure, which may make it difficult to smoothly supply the object to be processed. The present invention solves such a problem in a recycling vehicle, in which fine particles such as earth and sand which are not necessary to be crushed and which are contained in the object to be treated are removed in advance before being supplied to the crusher. As a result, it is an object of the present invention to provide a recycled vehicle capable of reducing the mixing of fine particles such as earth and sand into the product and improving the processing capacity.

[0007]

[Means for Solving the Problems]

 According to the present invention, a hopper for loading an object to be processed, a crusher for crushing the object to be processed supplied from the hopper, and an object to be crushed by the crusher are reprocessed on a sieve and a sieve on a trolley. A sieve that sifts to the product below, a conveyer that conveys the material crushed by the crusher from the crusher to the sieve, and a reprocessed material that has been sieved on the sieve and returns to the crusher In a recycling vehicle equipped with a return conveyor and a carry-out conveyor that carries out the sieved product to the outside of the vehicle, a grizzly vibration feeder is provided between the hopper and the crusher, and the grizzly vibration feeder is under the sieve. The above problem is solved by installing a discharge conveyor that discharges the fine particles of the above to the outside of the vehicle.

In this recycling vehicle, the object to be processed supplied to the hopper is quantitatively supplied to the crusher while removing fine particles such as earth and sand by the grizzly vibration feeder. The object to be processed supplied to the crusher is crushed, conveyed to the sieve by the conveyor and screened, the reprocessed product on the sieve is returned to the crusher by the return conveyor, and the product under the sieve is removed by the conveyor. It is taken out of the car. Fine particles such as earth and sand removed by the grizzly vibration feeder are discharged outside the vehicle by the discharge conveyor.

As described above, since the grizzling vibration feeder removes fine particles such as earth and sand from the object to be processed before putting it into the crusher, a large amount of fine particles are not mixed in the product, and a separate sieve is added. A product of appropriate particle size can be obtained without installation. In addition, since the grizzly vibration feeder cuts out the object to be processed by vibration, the adhesion of fine particles to the feeder is greatly reduced.

By providing a folding mechanism and a traversing mechanism, the discharge conveyor can secure a sufficient discharge distance to the outside of the vehicle at the time of work, and can be easily stored in a size range in which the truck can travel on a general road when traveling. You can
