Description

[0001]
[Industrial applications]
The mobile crusher of the present invention relates to a self-propelled mobile crusher that crushes rock collected at a mining site on site and produces aggregate and crushed sand for concrete and asphalt.
[0002]
[Prior art]
Conventionally, for the production of crushed stone, crushed sand, aggregate for concrete, and aggregate for asphalt, the mine was moved to a location near a rock mining site, where the mined rock was crushed on the spot, and the resulting crushed product was dumped by a dump truck. A mobile crusher that transports as it was was used. FIG. 3 shows an embodiment of a conventional mobile crusher. The mobile crusher 1 is equipped with a crusher 30 for crushing rocks received from a hopper 10 on a frame 3 of a crawler 2 running on an endless track by a caterpillar 2a. The output of the diesel engine 4 drives a hydraulic pump 6 and a hydraulic motor 7 via a rotary shaft 4 a and a chain wheel 5. As shown in FIG. 4, the crusher 30 uses a jaw crusher that inserts rock between a fixed crushing plate 35 and a movable crushing plate 36 that swings back and forth and crushes the rock. The movable crush plate 36 swings via the pulley and the eccentric rotation shaft 33. The crushed crushed product is discharged from the discharge path 30A to the outside of the machine by the belt conveyor 40. 33a is a flywheel.

A crusher, wherein the various devices are detachably attached to the frame and fastened to a plurality of boom cylinders which are vertically provided on both outer sides of the crawler, and are extended when a piston rod of the boom cylinder is extended. A separate device that can be erected on the ground via a boom cylinder and the remaining devices fixed on the frame can be separated, and the width between the boom cylinders is fixed on the frame. The gist is a mobile crusher that is wide enough to pass the remaining equipment.
The various devices described above consist of a hopper, a vibrating sieve, a crusher, a transport conveyor, a diesel engine, an oil tank, and a hydraulic unit. Therefore, the present invention provides a hopper, a vibrating sieve, a crusher, a transport conveyor on a movable crawler frame. A mobile crusher equipped with a diesel engine, an oil tank, and a hydraulic unit, wherein the various devices are detachable from the frame, and a plurality of boom cylinders are vertically installed on both outer sides of the crawler. , And can be separated into a separate device that can be erected on the ground via the boom cylinder when the piston rod of the boom cylinder is extended, and a remaining device fixed on the frame, and is preferable. Is a mobile crusher in which the width between the boom cylinders is such that the remaining equipment fixed on the frame can pass through. It is the gist.
Said separate devices are a hopper, a vibrating sieve and a crusher, which are integrally formed, so that the present invention provides a hopper, a vibrating sieve, a crusher, a transporter on a frame of a movable crawler. A mobile crusher equipped with a conveyor, a diesel engine, an oil tank, and a hydraulic unit, wherein these various devices are detachably attached to the frame, and a plurality of booms vertically installed on both outer sides of the crawler. A separate device integrally formed with a hopper, a vibrating sieve and a crusher that is fastened to a cylinder and can be erected on the ground via the boom cylinder when the piston rod of the boom cylinder is extended, and fixed on the frame; And the width between the boom cylinders preferably passes through the remaining equipment fixed on the frame. It is summarized as a possible width of mobile crusher.
The crusher described above is a jaw crusher or a cone crusher.
A preferred embodiment of the mobile crusher according to the present invention is a mobile crusher having a hopper, a vibrating sieve, a jaw crusher or a cone crusher, a transport conveyor, a diesel engine, an oil tank, a hydraulic unit, and the like mounted on a frame of a movable crawler. Wherein, of the devices mounted on the frame, the frame is detachably attached to the frame, and is fastened to a plurality of boom cylinders vertically provided on both outer sides of the crawler, When the piston rod is extended, a separate device that can be erected on the ground via the boom cylinder and the remaining device fixed on the frame are separable. The width between the boom cylinders is preferably such that the remaining equipment fixed on the frame can pass through.
[0005]
[Action]
In the mobile crusher according to the present invention, of the equipment mounted on the frame, a separate equipment which is detachable from the frame and which can be erected on the ground with the boom cylinder as a column base by extending the piston rod of the boom cylinder. , Which is separated from the rest of the main body equipment fixed to the frame, the above-mentioned separate equipment is erected on the ground via a boom cylinder on site, and the crawler mounted with the remaining equipment The main body is moved between the column pedestals, and is stopped at a predetermined position, and the separate device and the crawler frame are fastened and integrated. After these operations are completed, the piston rod of the boom cylinder is retracted to complete the operation.
