The movable crush plate 36 swings via the pulley and the eccentric rotation shaft 33. The crushed crushed product is fed from the discharge path 30A to the belt conveyor 40.
And is transported by a subsequent belt conveyor or other transport machine. 8 is an operator room.

[0003]

In the above-mentioned conventional mobile crusher, when rock is introduced into the raw material hopper 10 by a shovel loader, the rock is still collected at a mining site or a face, and is about 700 mm. Since a large mass is used, a large impact load is applied to the crushing portion of the crusher 30 disposed immediately below the raw material hopper 10, causing problems such as damage to equipment and shortened life. In addition, some of the supplied rocks contain sediment and sediment mixed when the mining site is blasted.
Since the fine grains crushed to about 0 mm are supplied to the crusher 30 together with the large blocks of rock, unnecessary crushing work is performed by mixing earth and sand with the crusher crushed product or supplying the fine particles together with the large blocks. There was a problem such as. In addition, with the arrival and departure of transport vehicles such as dump trucks for transporting crushed products, it is necessary to have an operator to stop and operate the vibrating feeder with grizzly to receive the raw material rocks. The transportation efficiency was poor because a time lag occurred for the supply to the truck.

[0004]

In order to solve the above-mentioned problems, in a mobile crusher of the present invention, a raw material hopper for receiving supplied rock and a large block of supplied rock are placed on a movable crawler. Doo and vibrating feeder with grizzly transferring while screened granules, placement and crusher to crush the Daikatamari, and transport aircraft crushed products, at the discharge end lower portion of the transport
It is equipped with a product hopper that stores a crushed product by providing an openable gate at the bottom and a raw material level gauge at the top, and removes sediment from the fine particles and discharges the sieved product to the transport machine. A vibrating sieve and an auxiliary transport machine for transporting the sediment are provided, and a bar code sensor for reading a bar code describing a load of the transport vehicle for receiving and transporting the crushed product is provided at a lower side of the product hopper. A control device for transmitting a command signal for opening and closing the gate of the product hopper in response to a signal received by the sensor, the vibrating feeder with grizzly, a crusher, a transporter, a gate of a product hopper, a vibrating sieve, and an auxiliary transport. The system was equipped with a diesel engine and a hydraulic unit as the power unit for driving the machine.

[0005]

In the mobile crusher of the present invention, the rock put into the raw material hopper falls into a robust vibrating feeder with a grizzly (also called a grizzly feeder), where fine particles and sediment are removed in advance. Since only the large mass is supplied to the crusher downstream thereof by the transfer action of the vibrating feeder with a grizzly, an unnecessarily large impact load or load is not applied to the crusher, which is advantageous in protecting the equipment. Fine particles and sediment that have passed through the grizzly beforehand are supplied to a vibrating sieve to be divided into fine particles and sediment, and the sediment is separately discharged to an auxiliary transport machine and fine particles on the sieve are transported under a crusher. Joined the machine. The crushed product stored in the product hopper with the gate closed beforehand is read by a barcode sensor on the side of the transport vehicle when a transport vehicle such as a dump truck enters the product hopper below the product hopper. A command signal is sent to the gate of the product hopper for the time corresponding to the time, the gate is opened, and the stored crushed products are loaded on the dump truck. On the other hand, when the storage amount of the product hopper during operation becomes full, a full signal from the raw material level meter enters the control device, and the vibrating feeder with grizzly, the crusher and other devices are sequentially stopped.
