DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled crusher, and more particularly to a self-propelled crusher including a crusher suitable for crushing rocks and concrete, and a shredder suitable for shearing plastics and the like.

[0002]

2. Description of the Related Art Conventional self-propelled crushers include, for example, a self-propelled crusher for crushing concrete or rock, and a self-propelled shredder suitable for shearing paper or plastic. The traveling crusher is selectively used depending on the material to be crushed.

FIG. 6 shows a conventional self-propelled crusher. A self-propelled traveling body 2 and a belt conveyor 3 for carrying crushed products to the outside are provided below a main body (main frame) 1. Having. A power unit 4 including an engine and a hydraulic pressure source is mounted on a rear portion of the main body 1, a crushing device 5 and a controller 6 are mounted on an intermediate portion, and a hopper 7 is mounted on a front portion of the main body 1. And a feeder 8 for feeding the material to be crushed into the hopper 7 to a crushing unit of a crushing device (crusher) 5. Further, at the forefront, the crushed raw material conveyed on the belt conveyor 3 is provided. A magnetic separator 9 for discharging the reinforcing bars and the like included in the above to the outside is attached.

[0004] The crushing device 5 comprises fixed teeth 11 and moving teeth 12.
And a pulley 1 attached to an output shaft of the hydraulic motor 13.
4, a pulley 15 attached to an eccentric shaft to which a moving tooth 12 is attached, and a V-belt 1 wound around pulleys 14 and 15.
6

In the self-propelled crusher, the moving teeth 12 are moved in the front-rear direction by a hydraulic motor 13 so that
The crushed material is crushed between the moving teeth 12 and the fixed teeth 11. Then, the crushed raw material is transported to the outside by the belt conveyor 3, and the reinforcing bars and the like contained in the raw material are separated by the magnetic separator 9 and discharged out of the machine.

On the other hand, in the self-propelled shredder, as shown in FIG. 7, a traveling body 2 and a belt conveyor 3 are attached to a lower portion of a main body 1 in the same manner as described above, and the power unit 4 is mounted on a rear portion of the main body 1. A crushing device (shredder) 10 for shearing an object to be crushed and a hopper 17 are mounted on a front portion of the main body 1, and a crushing roller 20 forming a pair of the crushing device 10 is driven in an intermediate portion of the main body 1. The hydraulic motor 18 and the controller 19 are mounted.

The crushing roller 20 of the self-propelled shredder crushing device 10 has a plurality of cutting blades provided on an outer peripheral portion thereof, and the rotating shafts are rotated in opposite directions so as to draw the crushed material therebetween. And crushing by shearing between adjacent blades. The raw material sheared by the shredder is discharged out of the machine by the belt conveyor 3.

[0008]

In the self-propelled crusher shown in FIG. 6, the distance between the hydraulic motor 13 for driving the crusher 5 and the pulley 15 on the crusher 5 side is equal to the distance between the pulley 14 of the hydraulic motor 13 and It is almost determined by the angle between the V-belt 16 and the pulley 15. The included angle of the V-belt 16 greatly affects slippage of the V-belt 16 and is an element that affects the life of the V-belt 16. Further, since the crusher 5 itself is a heavy object, the arrangement of the crusher 5 is determined in consideration of the weight balance. The hydraulic motor 13 is installed in front of the main body 1 in consideration of the life and weight balance of the V-belt 16.

On the other hand, in a self-propelled shredder shown in FIG. 7, a shredder 10 and a hydraulic motor 18 for driving the shredder 10 are provided.
Are integrated, the hydraulic motor 18 is mounted slightly behind the center of the main body 1 to maintain the vehicle weight balance.

As described above, since the positions of the hydraulic motors 13 and 18 are changed depending on the crushing device to be mounted, the arrangement of the pipes for supplying the pressure oil for driving the motors is different. The connection and connection between the main body 1 and the crushing devices 5 and 10 are performed by bolts and nuts.

As described above, the conventional self-propelled crusher has a plurality of models such as a self-propelled crusher and a self-propelled shredder depending on the object to be crushed, and the arrangement of each device is different depending on each model. Therefore, it does not have a configuration in which only the crushing devices 5 and 16 can be easily replaced. For this reason, the user must purchase a self-propelled crusher suitable for the raw material, which increases the economic burden on the user.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a self-propelled crusher having a configuration capable of providing a crusher having a crusher corresponding to various objects to be crushed with a small economic burden.
