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. 6 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 running 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. 7, the crusher 30 uses a jaw crusher that crushes the rock by charging and pressing 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 conventional mobile crusher described above, when a rock is thrown into the hopper 10 by a shovel loader, the rock remains collected at a mining site or at a face, and is about 700 mm. Because of the large mass, 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,
In order to supply rocks to the mobile crusher, loading machines such as power shovels and tractor shovels were required.

[0004]

In order to solve the above-mentioned problems, in a mobile crusher according to the present invention, a hopper for receiving a supplied rock, a tiltable device about a horizontal axis, is provided on a movable crawler. buckets and a boom and loader supplied from the hydraulic cylinder for tilt becomes Nozumi the rocks to scoop up the hopper such a vibrating feeder with grizzly transferring while selecting the supply rocks Daikatamari and fine, the Daikatamari < a crusher for crushing the crusher, a transporter for the crushed product of the crusher, and a vibrating sieve for removing sediment from the fine particles and discharging the on-screen product to the transporter; And an auxiliary transport machine for transporting the same, wherein the vibratory feeder with grizzly, crusher, loader, transporter, vibrating sieve, and a diesel engine and a hydraulic unit as a driving power unit for driving the auxiliary transporter are provided. It was constructed.

[0005]

In the mobile crusher of the present invention, the piled rock is supplied to the hopper by the loader. The rock put into the hopper falls onto a robust vibratory feeder with grizzly (also known as grizzly feeder), where fines and sediment are removed in advance, and only large blocks are transferred by vibrating feeder with grizzly. Since a constant amount is supplied to the crusher located downstream, an unnecessarily large impact load and a load are 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.

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

[0009] 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 the diesel engine 70 is started to confirm the start of each device, the rock piled up in the hopper 10 is supplied to the hopper 10 by operating the loader 100. The rock supplied to the hopper 10 is moved to the crusher 30 by the vibration feeder 20 with grizzly,
Fine particles and sediment pass between the grizzly rivers 20a, are separated into fine particles and sediment by the vibrating sieve 50, and the fine particles are transferred to the main conveyor 40 and the sediment is transferred to the side conveyor 60, respectively. The rock that has entered the crusher 30 by the vibrating feeder 20 with grizzly is crushed into fine particles set to a prescribed size, and is transported by the main conveyor 40 by a subsequent transport means, for example, a long belt conveyor. You.

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 a crusher, fine particles 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, since rock can be loaded using a loader mounted on a mobile crusher, there is no need to prepare a separate loading machine, and work can be performed closer to the face.

[0011]

As described above, the mobile crusher according to the present invention is configured as described above, and thus exhibits the following excellent effects. Crusher, conveyor, vibratory feeder with grizzly,
The vibrating sieve and the diesel engine and hydraulic unit that are the power source for these are mounted on the crawler, and each device is arranged in a lightweight and compact manner so that it can run on its own and can be moved to any mining site. 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. When loading raw material rocks, loading machines such as power shovels and yumbo are not required, and rocks piled up near the mining site can be loaded as they are. The transport of the crushed product can be arbitrarily selected, such as a subsequent belt conveyor or dump truck.
