In the conventional mobile crusher described above, when rocks are loaded into the raw material hopper 10 by the shovel loader, the rocks are still collected at the mining site or the cutting face, and are about 700 mm. Since it is a large block, a large impact load is applied to the crushing portion of the crusher 30 arranged immediately below the raw material hopper 10, which causes problems such as damage to the equipment and shortening of the service life. In addition, the amount of sediment that is mixed in at the time of blasting at the mining site and 20 to 3
Fine particles crushed to about 0 mm are supplied to the crusher 30 together with large rocks, so crushed products are mixed with earth and sand, or unnecessary particles are supplied together with large lumps to perform unnecessary crushing work. There was a problem such as. In addition, with the arrival and departure of a transportation vehicle such as a dump truck that transports the crushed products, an operator is required to stop and operate the vibrating feeder with grizzly that receives the raw rock, and the crushed products are crushed and dumped. Transportation efficiency was poor because there was a time lag for the trucks to be supplied.

[0004]

In order to solve the above-mentioned problems, in the movable crusher of the present invention, a raw material hopper for receiving the supplied rock and a large mass of the supplied rock are provided on a crawler that can travel.

[0005]

In the mobile crusher of the present invention, the rocks thrown into the raw material hopper fall on a vibrating feeder with a grizzly grip (also called grizzly feeder), where fine particles and sediment are removed in advance. Only the rocks are supplied to the crusher downstream by a fixed amount by the transfer action of the grizzled vibrating feeder, which is advantageous in protecting the equipment without applying an excessively large impact load or cumulative load to the crusher. The fine particles and sediment that have passed through the grizzly in advance are supplied to the vibrating sieve and separated into fine particles and sediment. The sediment is separately discharged to the rib replacement machine, and the fine particles on the sieve are under the crusher. Merged with transport aircraft. The crushed product stored in the product hopper with the gate closed in advance is controlled by the control device based on the signal from the sensor when the transportation vehicle such as a dump truck is in the standby state under the product hopper. A command signal is sent to the gate of the car to open the gate, and the crushed products stored are loaded into the dump truck. On the other hand, when the storage volume of the product hopper during operation becomes full, a full signal from the raw material level meter enters the control device and the grizzled vibrating feeder, crusher and other equipment are stopped in sequence.
