Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled mobile crusher used for collecting and crushing rocks and the like.

[0002]

2. Description of the Related Art Conventionally, for the production of aggregates for crushed stones, concrete and asphalt, the crushed stones have been moved to a rock mining site or in the vicinity of a cutting face and crushed on the spot to crush the rocks. A mobile crusher was used to transport the slab as it was. FIG. 6 shows an embodiment of the mobile crusher 1, in which a crusher 30 for crushing rock received from a hopper 10 is loaded on a frame 3 of a crawler 2 which travels by an endless track by a caterpillar 2a, and an output of a diesel engine 4 is output. The hydraulic pump 6 and the hydraulic motor 7 are driven via the rotary shaft 4a and the chain wheel 5. As shown in FIG. 7, the crusher 30 uses a jaw crusher for crushing by rocking the rock between a fixed crushing plate 35 and a movable crushing plate 36 that swings forward and backward, and uses a V belt, V The movable crush plate 36 is swung through the pulley and the eccentric rotation shaft 33. The crushed crushed products are fed from the discharge passage 30A to the belt conveyor 40.
Is discharged to the outside of the machine by a belt conveyor and other transportation machines. 8 is an operator room.

[0003]

In the conventional movable crusher described above, when rocks are put into the 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 lump, a large impact load is applied to the crushing portion of the crusher 30 arranged immediately below the hopper 10, which causes problems such as damage to equipment and shortening of life. Also, in the supplied rock, the crusher 30 together with the large rocks, the sediment content mixed at the time of blasting at the mining site and the fine particles already crushed to about 20 to 30 mm are included.
Since it was supplied to the crusher, there were problems such as soil and sand being mixed in the crusher crushed product, and unnecessary crushing work being performed by supplying fine particles together with a large lump.

[0004]

In order to solve the above-mentioned problems, in the movable crusher of the present invention, a hopper for receiving the supplied rock and a large mass of the supplied rock are provided on a movable crawler. A vibrating feeder with grizzly that sorts and transfers it to fine particles, and a crusher that crushes the rock,
A grinder is equipped with a crushed product transporter, and is provided with a vibrating screen that removes sediment from the fine particles and discharges the sieve product to the transporter, and an auxiliary transporter that transports the sediment. It was equipped with a diesel engine and a hydraulic unit as a power unit for driving the attached vibrating feeder, crusher, transport machine, vibrating screen, and auxiliary transport machine.

[0005]

In the mobile crusher of the present invention, the rocks thrown into the hopper fall onto a vibrating feeder with grizzly grips (also called grizzly feeders), where fine particles and sediment are removed in advance and the rocks are removed. Only by the transfer action of the vibrating feeder with grizzle, it is supplied to the crusher located downstream of the crusher in a fixed amount, which is advantageous in terms of equipment protection because an unnecessarily large impact load or cumulative load is not applied 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 auxiliary transport machine and the fine particles on the sieve are transported under the crusher. Join the plane.

The movable crusher 1 is provided on a frame 3 of a crawler 2 which is run by an endless caterpillar 2a, a hopper 10 and column-shaped pedestals 10a and 10b, and a vibrating feeder 20 with a grizzle disposed below the hopper 10. As shown in FIGS. 2 and 3, the grizzling vibrating feeder 20 has a plurality of parallel grizzle bars 20a arranged at appropriate intervals in the longitudinal direction, and the whole of the greasing vibrating feeder 20 faces horizontally or downstream toward the downstream. It is slightly inclined to the upper side, and is configured so that the driving motor 20b can give high-speed micro-vibration for transferring the load to the downstream side. A chute 21 is provided below the grizzling vibrating feeder 20 to receive fine particles and sediment that have passed between the grizzling rivers 20a and sort the fine particles and sediment, for example, a vibrating screen 50 having a mesh of 10 mm is provided. Under the vibrating screen 50, the auxiliary screen 6 is collected under the screen and protrudes to the side surface of the movable crusher 1.
A chute is provided to drop to zero. On the other hand, a chute is provided so that the fine particles on the screen of the vibrating screen 50 can be dropped to the transportation machine 40 described later. Vibration feeder with grizzling 2

As described above, in the mobile crusher of the present invention, when crushing the rock collected at the mining site or face by the crusher, fine particles and sediment are removed by the vibrating feeder with grizzly, so that impurities are removed. High-quality aggregate can be produced because only the large lumps are crushed. Fine particles that do not need to be crushed pass through under the grizzly river before being sent to the crusher and are removed beforehand. The impurities and sediment are removed and the crushed products of the crusher are combined later to improve the production efficiency. Good and can prevent the generation of unnecessary fine particles.
