Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The crushing equipment of the present invention is a combination of a self-propelled mobile crusher for crushing rocks or the like at a mining site and a plurality of mobile conveyors connected thereto.

[0002]

2. Description of the Related Art Conventionally, a mobile crusher has been used for manufacturing aggregates for crushed stones, concrete, and asphalt, and moving to a rock mining site or in the vicinity of a cutting face and crushing the mined rock on the spot. The resulting product was then loaded into an open field, then loaded onto a dump truck with a power shovel and secondly crushed to be transported to a crushing stone factory where aggregate and sand are manufactured. As shown in FIG. 8, the mobile crusher 1 that has been used up to now is a crawler 2 that travels on an endless track by a caterpillar 2a.
A jaw crusher 30 for crushing the rock received from the hopper 10 is loaded on the frame 3 and the output of the diesel engine 4 is driven by the hydraulic pump 6 and the hydraulic motor 7 via the rotary shaft 4a and the chain wheel 5. As shown in FIG. 9, the jaw crusher 30 throws rocks between the fixed crushing plate 35 and the movable crushing plate 36 that swings back and forth to crush the rocks.
Swing the V pulley and the eccentric rotation shaft 36. The crushed crushed product is discharged from the discharge path 30A to the outside of the machine by the belt conveyor 40. The above operation management is performed in the operator room 8.

In such a conventional mobile crusher, most of the rocks collected at the mining site are block-shaped rocks containing a large block of about 700 mm, and a large amount of sediment and blasting are involved. It contains a large amount of fine particles of rock debris generated in mine and it is difficult to produce only high-purity aggregate at the mining site. Moreover, as shown in FIG. 10, the piston transportation is repeated in the dump truck until the crushed stone factory far away from the mining site is obtained only by obtaining a crushed product having a raw material size of about 150 mm to be used for the secondary crushing. The labor cost was high and the cost was high.

[0004]

Therefore, the inventor of the present invention
As shown in FIG. 11, a crushing facility for transporting crushed products of the crusher to, for example, a permanent crushing stone factory by connecting a movable conveyer and a fixed conveyer, which are the same as the self-propelled movable crusher, to each other. Proposed. This eliminates the need for transportation means such as dump trucks, thus significantly reducing transportation costs. However, with this method, the mobile conveyor requires a self-propelled function equipped with a diesel engine or generator device, and requires a new layout of the mobile conveyor due to a change in the mining site. ， This work took time.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems and to easily and quickly deal with the high-purity primary crushed products even if the mining site is changed to a fixed location such as the nearest quarry factory. According to a first aspect of the present invention, there is provided a crushing facility including a mobile crusher and a plurality of mobile conveyors for transporting the crushed products of the mobile crusher, wherein the crusher is provided between the mobile crusher and a subsequent mobile conveyor, and A crushing facility was used in which each movable conveyor was connected by a pin joint that was rotatable around a vertical axis. The crushing equipment of the second invention is the first
The mobile crusher of the invention of claim 1 is provided with a hopper for receiving a supplied rock, a vibrating feeder with a grizzle for transferring the supplied rock into large lumps and fine particles, and crushing the rock, on a crawler that can travel freely. A jaw crusher, a transporter for crushed products, a vibrating sieve that removes sediment from the fine particles and discharges the sieve top to the transporter, an auxiliary transporter that transports the sediment, and a drive for each device. It has a diesel engine and hydraulic unit.

[0006]

In the crushing equipment of the present invention, the mobile crusher is moved to the immediate vicinity of the mining site, and the soil content and fine particles mixed with the rock are removed in advance by the vibrating feeder with grizzly and then the rock is crushed by the jaw crusher. .. The crushed products are guided to a plurality of mobile conveyors connected to a mobile crusher, transported to a predetermined fixed position, that is, a crushed stone factory of permanent equipment nearest to the mining site, and secondarily processed and aggregated. And produce sand. When the mobile crusher moves due to a change in the mining site, the subsequent mobile conveyor connected to it with a pin joint is pulled by the mobile crusher and moves following it, so the layout is changed automatically.
Work can be resumed immediately after the change.
