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, as a method for producing crushed stone, aggregate for concrete and aggregate for asphalt, the crushed rock obtained by moving to a rock excavation site or immediately adjacent to a face and crushing the mined rock on the spot is obtained. A mobile crusher that transports the raw material as it is was used. FIG. 7 shows an embodiment of the mobile crusher 1 in which a crusher 30 for crushing rocks received from a hopper 10 is mounted on a frame 3 of a crawler 2 traveling on an endless track by a caterpillar 2a, and the output of a diesel engine 4 is shown. Is driven via a rotary shaft 4a and a chain wheel 5 to a hydraulic pump 6 and a hydraulic motor 7. As shown in FIG. 8, the crusher 30 uses a jaw crusher that crushes the rock by charging the rock between the fixed crush plate 35 and the movable crush plate 36 that swings back and forth.
The movable crush plate 36 swings from the hydraulic motor 7 via the V belt, the V pulley, and the eccentric rotating shaft 33. The crushed crushed product is discharged from the discharge path 30A to the outside of the machine by the belt conveyor 40, and is transferred by the subsequent belt conveyor or another transport machine. 8 is an operator room.

[0003]

In the above-mentioned conventional mobile crusher, when rock is introduced into the hopper 10 by a shovel loader, the rock remains collected at the mining site or at the face, and is about 700 mm. A large impact load is applied to the crushed portion of the crusher 30 disposed immediately below the hopper 10, causing problems such as damage to equipment and shortened life. In addition, in the supplied rock, sediment mixed in the blasting of the mining site and fine grains already crushed to about 20 to 30 mm together with the massive rock are crushers 30.
Therefore, there is a problem in that sediment is mixed into the crusher crushed product, and unnecessary crushing work is performed by supplying fine particles together with large lumps. Also,
Large lumps of 700 mm or more, which is the maximum processing size of the occasional crusher (jaw crusher), are supplied. The large lumps stay at the top of the crusher and do not move without being bitten. In this case, the operation was unavoidably stopped, and the large block was hung with wires and removed with a crane or other cargo-handling machine. Production efficiency was significantly impaired.

[0005]

In mobile crusher the present invention, for example, rocks thrown into the hopper (also referred to as alias grizzly feeder.) Robust vibrating feeder with grizzly to fall, fine and sediment fraction were previously removed here Only the top rock is supplied quantitatively to the crusher located downstream by the transfer action of the vibrating feeder with a grizzly, so that an unnecessarily large impact load and integrated load are not applied to the crusher, which is advantageous in protecting the equipment. Also, the fine particles and sediment that have passed through the grizzly beforehand are supplied to the vibrating sieve and divided into fine particles and sediment,
The sediment is separately discharged to the auxiliary transport machine, and the fine particles on the sieve are joined to the transport machine below the crusher. In addition, when a large block that cannot pass through the crusher stays on the crusher, the rock grasper is operated to remove the large block from the crusher and the operation is continued.

An inclined side wall may be provided at the top of the vibrating feeder 20 with a grizzly.

As shown in FIGS. 1 and 2, a stone gripper 100 is installed near the crusher 30. The stone gripper 100 is supplied to the crusher 30 and is supplied to the crusher 3.
The crusher removes and discharges large blocks of rocks of about 700 mm or more that cannot be processed by the crusher.
Leak that is mounted on the wing and turns horizontally around a vertical axis, and is vertically movable up and down by the operation of two hydraulic cylinders.
A pair of clamps 100e and 100f that are rotatable about 00b and 100c and a pin fulcrum 100d and that open and close by the operation of a third hydraulic cylinder and grip rock. FIG. 2 shows the turning ranges (shaded portions) of the links 100b and 100c, which can move in a fan-shaped range including the vibration feeder 20 with grizzly and the crusher 30. Therefore, as with the large rocks above the crusher 30, large rocks staying in the hopper 10 of the vibrating feeder 20 with grizzly can also be removed. The clamps 100e, 1
00f may open and close in accordance with the advance and retreat of the hydraulic cylinder 103. The mechanism may use gears to rotate in opposite directions, or, as shown in FIG. And a link 100g whose one end is pivotally supported by the edge of the clamp 100f and the other end is pivotally supported by the edge of the clamp 100e. The hydraulic cylinder 103 moves the clamps 100e and 100f simultaneously in opposite directions. May be rotated.

The operation of the mobile crusher of the present invention configured as described above will be described. Mobile crusher 1
The front end (right side in FIG. 1) is directed to the mining site, and after starting the diesel engine 70 to confirm the start of each device, the collected rock is supplied to the hopper 10 by a transport machine such as a shovel loader. While the rock supplied to the hopper 10 is moved to the crusher 30 by the vibrating feeder 20 with grizzly, fine grains and sediment pass between the grizzly bars 20a, and are separated into fine grains and sediment by the vibrating sieve 50.
The fine particles are transferred to the main conveyor 40, and the sediment is transferred to the side conveyor 60. The rock that has entered the crusher 30 by the vibrating feeder 20 with grizzly is crushed into fine granules set to a prescribed size to form the main conveyor 40.
Is transported by subsequent transportation means, for example, a long belt conveyor. When a large lump stays on the hopper 10 or the crusher 30, the stone gripper 100 is operated as needed to remove and move the large lump.

As described above, in the mobile crusher of the present invention, when rocks collected at a mining site or at a face are crushed by the crusher, fine grains and sediment are removed in advance by a vibrating feeder with grizzly. Since only large lumps are crushed, high quality aggregate can be produced. Fine particles that do not need to be crushed pass under the grizzly river before being sent to the crusher and are removed beforehand. After removing impurities such as sediment, they merge with the crushed products of the crusher, so the production efficiency is reduced. And the generation of unnecessary fine particles can be prevented. In addition, even if large lumps that are difficult to process with a crusher are supplied, they can be removed by a stone gripper and continuous operation can be continued.

[0012]

As described above, the mobile crusher according to the present invention is configured as described above, and thus exhibits the following excellent effects. Crushers, conveyors, vibratory feeders with grizzly, vibrating sieves, and a diesel engine and hydraulic unit that are the power source for these are mounted on the crawler, and each device is lightly and compactly arranged so that it can run on its own. It can also be moved to mining sites. Aggregate with impurities removed can be produced, and production efficiency is high. Since each device is driven by a hydraulic motor driven by a diesel engine, it does not require any power supply and can be run or crushed every day just by replenishing fuel oil periodically. The method of loading the raw rock can be freely selected, such as power shovel, yumbo, dump truck, etc., and no special loading equipment is required. The transportation of the crushed product is optional, such as a belt conveyor and a dump truck. Since the stone gripper is installed, large lumps staying in the hopper or crusher can be quickly removed and processed, so that continuous operation is possible.
