Description

[0001]
[Technical field to which industry belongs]
The mobile crusher of this invention is related with the self-propelled mobile crusher which crushes the rocks etc. which were extract | collected in the mining site on the spot, and produces the aggregate for concrete and asphalt, and crushed sand.
[0002]
[Prior art]
Conventionally, for the production of crushed stone, crushed sand, concrete aggregates and asphalt aggregates, the rocks were moved to the nearest mining site, and the mined rocks were crushed on the spot, and the obtained crushed products were dumped on a dump truck. A mobile crusher was used to transport it as it was. 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 that runs on an endless track by a caterpillar 2a. The hydraulic pump 6 and the hydraulic motor 7 are driven by the output of the diesel engine 4 through the rotating shaft 4a and the chain wheel 5. As shown in FIG. 4, the crusher 30 uses a jaw crusher that inserts and crushes rocks between a fixed crushing plate 35 and a movable crushing plate 36 that swings back and forth. The movable crushing plate 36 is swung through the pulley and the eccentric rotating shaft 33. The crushed crushed product is discharged out of the machine by the belt conveyor 40 from the discharge path 30A. 33a is a flywheel.

[Problems to be solved by the invention]
In such a conventional mobile crusher, all the devices mounted on the crawler frame are fixed, and the total height of the device is usually as high as about 5500 mm to 6000 mm. Therefore, when moving from the face to the face in the quarry, it was impossible to pass through the tunnel with a low ceiling, and it was inconvenient to move around the tunnel, resulting in a loss of work time.
[0004]
[Means for solving problems]
In order to solve such a problem , the present invention is a mobile crusher in which a crusher, a vibration sieve, a transport conveyor, a diesel engine, and a hydraulic unit are mounted on a frame of a crawler that can run freely. Among these devices, a device that occupies a relatively high position during operation is disposed so as to be movable up and down or tilted, and a mobile crusher in which the height during movement is 60 to 70% of the height during operation is set. It is a summary. Equipment that occupies a relatively high position during the above operation is a transport conveyor and a vibrating screen, and is arranged to be movable up and down or tilted via a telescopic link mechanism and a hydraulic cylinder. A mobile crusher equipped with a crusher, vibrating sieve, transport conveyor, diesel engine, and hydraulic unit on a flexible crawler frame, and the transport conveyor and vibrating sieve occupying a relatively high position during operation can be raised or lowered. The gist of the mobile crusher is such that it can be tilted and the height during movement is 60 to 70% of the height during operation.
The crusher is a jaw crusher or cone crusher.
Therefore, a preferred embodiment of the mobile crusher of the present invention is a mobile crusher in which a crusher such as a jaw crusher or a cone crusher, a vibration sieve, a transport conveyor, a diesel engine, a hydraulic unit, etc. are mounted on a frame of a crawler that can run freely. Transportation conveyors and vibrating screens that occupy a relatively high position during operation are arranged to be movable up and down or tilted via a telescopic link mechanism and a hydraulic cylinder. it is obtained by a 60% to 70% compared to the high.
[0005]
[Action]
In the mobile crusher of the present invention, when moving to the face including the tunnel, the link mechanism and the hydraulic cylinder attached to the transport conveyor and the vibrating screen are operated to lower the overall machine height by operating the link mechanism and the hydraulic cylinder. Without passing through the tunnel.

【Example】
Embodiments of the mobile crusher of the present invention will be described below with reference to the drawings.
The present invention is not limited by these examples.
[0007]
Example
1 to 2 show an embodiment of a mobile crusher according to the present invention, FIG. 1 is a side view during operation, and FIG. 2 is a side view during movement.
In the figure, 100 is a mobile crusher, 110 is a feed conveyor, 120 is a vibrating sieve, 130 is a cone crusher, 140 is a diesel engine, and 150 is a conveyor for transporting products. Reference numerals 160 and 162 denote hydraulic cylinders. Reference numerals 170 and 172 denote links of a link mechanism that connects the frame 103 of the crawler 102 and the vibrating screen 120, and each end portion is a pin hinge. Therefore, at the time of movement in FIG. 2, the piston rod of the hydraulic cylinder 160 is extended, the piston rod of the hydraulic cylinder 162 is contracted, and the links 170 and 172 are bent to lower the vibrating sieve 120. On the other hand, the transport conveyor 110 is supported at the center by a pin hinge 110b at the tip of the column 110a, and the right end of the vibrating screen 120 and the pin hinge 110c are connected at the left end in the figure. As a result of the change to the state, the total machine height is lowered to about 0.6 to 0.7 of the total machine height H during operation of FIG. In the operation of FIG. 1, since the total weight of the vibrating screen 120 is large, in order to maintain this state, the stand 180 is placed between the ground and the vibrating screen 120 to support the load of the vibrating screen 120.
[0008]
As described above, by configuring the vibrating sieve 120 and the transport conveyor 110 so as to be movable up and down or tilted, for example, the total machine height H is 5 m, and the total machine height is reduced to 3 to 3.5 m, which is low. Even tunnels with a ceiling height can be easily passed. It should be noted that a crusher, a diesel engine, or the like installed at a relatively low position is not hindered even if it remains fixed on the frame.
[0009]
【The invention's effect】
As described above, in the mobile crusher of the present invention, the device at a relatively high position is configured to be movable up and down or tilted, so that the site can be moved on the shortest route without detouring the tunnel. Therefore, the setup time is reduced and the production efficiency is improved.
