DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing plant for crushing aggregates such as concrete, asphalt, rocks and the like generated in buildings, structures, excavations, etc. to a desired size to produce reusable crushed materials. TECHNICAL FIELD The present invention relates to a crushing plant vehicle capable of traveling on a road installed on a trailer capable of traveling on a general road towed by being connected to a tractor.

[0002]

2. Description of the Related Art In recent years, especially in cities, residential areas, and urban areas, demolishing and rebuilding of middle- and high-rise houses, buildings, structures, and the like built during the pioneering period of rapid growth have been actively performed.
Redevelopment is underway. However, at that time, as a method of treating the aggregates such as concrete and asphalt generated, the dumping process, which has been general, has no place for dumping the aggregates, so it cannot be easily dumped as in the past. Problems such as illegal dumping have also arisen. Therefore, a method of reusing or recycling waste materials such as buildings and structures, and concrete or asphalt, to effectively use resources to be used, and reducing the amount of discarded materials has been used. In other words, it is necessary to crush lumps such as concrete and asphalt using a crusher, and to reuse the crushed materials as road surface materials, foundation materials such as buildings and structures, and backfill materials after excavation. Began to take place.

[0003] If crushed materials are recycled by processing lumps such as concrete, asphalt, waste materials, etc. at the generation site, landfill disposal sites and dumping locations for these lumps are determined, and the lumps are collected. This eliminates the need for the cost of transporting vehicles over long distances and eliminates the destruction of the environment due to the dumping of lumps, and also makes effective use of limited resources such as gravel, which is extremely effective. .

[0004] Most of the crushing plants for crushing aggregates such as concrete, asphalt, waste materials and the like are crushing plants of an installation type which are installed and used in a treatment plant. A generator, conveyor, etc. are mounted and transported to the specified processing plant. At the processing site for the lump, a crusher is lowered from the trailer and installed.
At present, lump is transported to the treatment plant. Such crushing plants basically consist of concrete,
It is composed of a crusher for crushing lump such as asphalt and waste materials, a sorting mechanism for sorting crushed crushed materials, and a driving device such as a generator. In addition, mobile crushing plant vehicles that can move within the treatment plant have been developed as crushing plants. However, these mobile crushing plant vehicles move only at the treatment plant and are legally required to travel on general roads. I could not run.

Further, as a working vehicle equipped with a crusher on a vehicle, there is, for example, an apparatus for crushing and sorting waste soil disclosed in Japanese Utility Model Laid-Open No. 2001-142142. There is also disclosed a use example in which the crushing and sorting device is mounted on a vehicle. However, these crushing and sorting devices are intended only for the treatment of waste soil, and are used for concrete and the like as waste materials of buildings and structures. It is not intended for hard materials. Therefore, these crushing and sorting devices cannot crush hard materials such as concrete, asphalt, and waste materials.

Similarly, another example of a work vehicle equipped with a crusher in a vehicle is a utility pole crush work vehicle disclosed in Japanese Utility Model Laid-Open No. 58-10050. The utility pole crushing vehicle is used for crushing utility poles with a press machine and then further crushing with a roller crusher. It is intended only for special structures such as utility poles and is not intended for crushing hard materials such as massive concrete waste. As a result, the continuous crushing of massive concrete waste could not be performed.

[0007]

However, for the stationary crushing plant or the mobile crushing plant as described above, a crushing plant should be constructed in the vicinity of a place where lumps such as concrete and asphalt are generated. Is becoming more difficult due to soaring land prices in urban areas. In addition, there is a problem that transporting the lump to a distant crushing plant requires too much transportation cost. In addition, even if a crushing plant can be built close to the place where the lump is generated, the operation of the crushing plant generates noise and vibration, which is not desirable.
Particularly, it is not preferable in an urban area or a residential area.

Further, as the capacity of a crushing plant increases, the size of the crushing machine increases, and accompanying devices such as a conveyor also increase in size. Even if the above mobile crushing plant has wheels, traveling on the road is limited by the safety standards (hereinafter simply referred to as security standards) of the Road Transport Vehicle Law, which limits the width and height of the vehicles. When the crushing plant is mounted, the crushing plant can be moved only inside the crushing plant, and the above-mentioned problem in which it is difficult to secure the processing plant cannot be solved. To move the crushing plant to the site of demolition of buildings and structures and use it, load the crusher on a trailer that can run on the road and transport the crusher to the site of demolition. Therefore, it was necessary to drop crushers and other equipment from the trailer on site and assemble them. However, since these devices are heavy and large devices, the transporting and assembling work is a large task, requiring a lot of manpower and increasing the cost.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and includes waste materials of buildings and structures, concrete,

Since the crushing plant vehicle capable of traveling on the road according to the present invention is constructed as described above, when installing the crushing plant on the vehicle body frame, the vehicle width and the vehicle height are set so that the vehicle can run on a general road. In consideration of the weight balance, the conveyor and return conveyor for connecting the crusher and the vibrating sieve are constructed so that they can be expanded or contracted, and the height of the plant can be reduced if necessary. Safety standards can be met, the trailer can be driven on a general road with the crushing plant loaded and equipped, and if the trailer can run, the crushing plant can be moved to the site where crushed material waste is generated. It can be easily transported, and crushing of waste materials such as concrete and asphalt can be performed while the crushing plant is mounted on the trailer.

In the case of a stationary crushing plant installed in a conventional waste material treatment plant, the waste material must be transported from a waste material generation site to a waste material treatment plant using a vehicle or the like. This has contributed to traffic congestion and increased processing costs. On the other hand, with this crushing plant vehicle that can be driven on the road, the crushing plant can be easily transported to the waste material generation site, and the waste material such as concrete and asphalt can be crushed on the spot. It is possible to reduce the waste of transporting at a distance, and to greatly reduce the processing cost.

In this crushing plant vehicle, in particular, when crushing waste material, the front part of the trailer extends the outrigger provided at the front part of the trailer to the vehicle height of the tractor so as to contact the ground, and the rear part of the trailer is used. The crushing plant, such as a crusher or vibrating sieve, operates while the trailer is supported by the trailer's rear wheel via the air cushion and leaf spring that the trailer originally has, so the impact force and vibration generated by the crusher, etc. The force of this can be buffered not only by the rear wheels but also by air cushions and leaf springs, and vibration and noise can be reduced as much as possible when crushing massive objects. Even if it does, the crushing work can be performed in the environment within the noise regulation range without deteriorating the environment to the surroundings. Therefore, if this crushing plant vehicle is used, it can be processed at the site where lumps such as concrete and asphalt are generated, and the granules can be recycled at the site as a substitute for gravel and the like. There is no need to move to the processing site and remove the crushing plant from the trailer again, and the lump can be immediately crushed again with the trailer set.
