In general, construction wastes are generated from the dismantling of construction structures of buildings and civil works, and in particular, in recent years, a large amount is generated by active reconstruction of apartments according to the urban development plan.

Construction wastes generated during the reconstruction of construction structures destroyed by floods, etc. and the reconstruction of old buildings include aggregates, earth and sand, waste concrete, rebars, styrofoams, waste wood, vinyls, and papers.

Soil and waste concrete among such construction wastes can be recycled, so that it is possible to reduce the cost of purchasing raw materials by recycling them with other kinds of construction wastes, and reduce environmental pollution and destruction. To this end, the Waste Management Act stipulates the criteria for recycling recycled construction materials such as recycled aggregates and earth and sand into landfills, subsidiary materials, road substrates or cover materials to less than 1% by volume.

However, since it is difficult and inconvenient to sort construction wastes by type, most companies dispose of all recyclables, and thus there is a problem of destroying the natural environment due to waste of resources and environmental pollution due to landfilling of wastes.

In order to solve this problem, construction wastes are sorted by type.

As a method for screening foreign matters from construction wastes, it is common for a worker to visually identify the wastes in a hopper in which construction wastes are stored, and manually separate the wastes into aggregates, concretes, rebars, styrofoams, woods, papers, and vinyls.

On the other hand, construction wastes contain foreign matters such as dust to sort out foreign matters for recycling of construction wastes.

The foreign matter sorting according to the prior art is usually as shown in Figure 1, by transporting the wind through the blower (2) to the construction waste that is transported through the conveyor belt (1) and falling to remove the foreign matter (W) contained in the construction waste Screening from construction waste The foreign matter separated from the construction waste by the blower 2 is loaded into the construction waste treatment plant. The foreign matter (W) is left in the construction waste treatment plant without being loaded in a separate loading facility. If a certain amount is loaded, the foreign matter (W) is loaded in a transport vehicle and transported to the foreign matter processing facility.

However, according to the foreign matter sorting device included in the construction waste according to the prior art has the following problems.

Foreign substances (W) selected from construction waste are left untreated in the treatment plant, and the working environment of the treatment plant is not good, and the foreign substances (W) left in the treatment plant are scattered to the surroundings, causing serious environmental pollution, resulting in civil complaints. There is a disadvantage in that a lot of money is required for the purchase of the site because the space for the loading of foreign matters (W) to be secured.

Even if the above-mentioned disadvantages are overlooked, the work of sorting the foreign matter from the construction waste and the task of loading the selected foreign matter into the vehicle have to be performed separately.

The present invention is to solve the above-mentioned problems, to provide a foreign matter screening device for sorting foreign matter from the construction waste, and to treat the selected foreign matter without leaving the construction waste treatment plant. There is this.

Another object of the present invention is to allow a process of sorting foreign matters from construction waste and a process of loading the selected foreign matters on a vehicle and the like as a series of processes.
