Description

Self-propelled soil selector {Frequently the earth and sand selector}

The present invention relates to a self-propelled earth and sand separator, and more particularly, to sewage used to prevent the flow and breakage of the embedded pipe or cable in the aggregate and soil obtained through the trench when the pipe or cable is installed or replaced in the ground. The present invention relates to a self-propelled earth and sand sorter which can be easily sorted and supplied without interruption.

Generally, the mixture material obtained by digging in industrial sites, construction sites, and roads includes soil, sand, aggregate, steel, wood, etc., which can be reused for building materials or road paving materials using a sorting device. To be separated.

That is, the conventional sorting device is to put a mixture of soil, sand, aggregate, steel, wood, etc. to sort and recycle by type, among which the sorting machine drills a hole at a predetermined interval in the cylindrical drum drum Is installed horizontally or slightly inclined so that the mixture can be rotated by using a conveyor installed in the upper feeder. As the drum rotates, soil or sand smaller than the diameter of the hole is discharged downward through the hole and larger than the diameter. Aggregate and the like is configured to be discharged to the other side by taking a cylindrical drum.

In particular, the conventional sorting machine is widely used for sorting sand, soil and aggregate, but the biggest problem in use is that the sand or soil containing water when the mixture containing a large amount of water blocked the holes of the drum was impossible to sort.

Therefore, one method to solve the above problems and increase the efficiency is to stop the work periodically to drill the hole of the drum periodically and artificially shake off the soil or sand that clogged the drum hole manually, so many times There is a drawback that requires a lot of effort and effort, so an alternative solution is required.

For example, the Republic of Korea Patent Registration No. 10-0160227 (registered on August 17, 1998) sand separator, the Utility Model Registration No. 20-0312535 (registered on April 24, 2003) to prevent clogging of the discharge hole of the cylindrical drum, the Utility Model No. 20 -0349345 (registered on April 24, 2004) A sorter hole clogging prevention device has been disclosed.

The devices are installed to contact the hair plate, the impact belt, the elastic material to the outside of the cylindrical drum, and to blow or vibration generated when the drum rotates to shake off the sand, dirt, etc. blocked in the perforated hole, the impact or vibration Due to the complicated structure, the production cost is increased, and the wear caused by contact is severe, and thus the material contacting the drum needs to be replaced at any time, which causes a great deal of trouble, increase in labor cost, and loss due to delay in working time.

In addition, the Republic of Korea Patent No. 10-0203410 (registered on March 23, 1999) waste landfill sorting device, and Patent Registration No. 10-0694234 (registered on March 6, 2007) screen sorting prevention device of the waste sorter It became.

The apparatus is equipped with a burner or a nozzle moving to the outside of the cylindrical drum to the left and right to dry the sand and soil by combustion heat or by using compressed air to shake off the sand, soil, etc. blocked in the perforated hole, the combustion heat Or the disadvantage of requiring expensive equipment for generating compressed air, and the complicated structure for supplying this combustion heat or compressed air, which leads to an increase in manufacturing cost, and additional costs incurred by the use of combustion fuel and electricity, and the structure is complicated. As a result of frequent breakdowns, there was a problem in that the loss due to the increase of the labor cost of labor and the delay of working time was great.

And the conventional sorting devices operate in the most fixed state, so there was a inconvenience to move the collected mixture and separated sand, soil or aggregate to separate equipment from time to time.
