[0002]
[Prior art]
Conventional self-propelled crushers include, for example, self-propelled crushers for crushing concrete and rocks, and self-propelled shredders suitable for shearing paper or plastic. These self-propelled crushers are Depending on the material to be crushed, it is selected and used.
[0003]
FIG. 6 shows a conventional self-propelled crusher. A self-propelled traveling body 2 and a belt conveyor 3 for carrying out the crushed material to the outside are provided at a lower portion of a main body (main frame) 1. A power unit 4 including an engine and a hydraulic pressure source is mounted on the rear portion of the main body 1, a crushing device 5 and a controller 6 are mounted on the intermediate portion, and a hopper 7 is mounted on the front of the main body 1. And a feeder 8 for feeding a material to be crushed into the hopper 7 to a crushing unit of a crushing device (crusher) 5, and a crushed raw material conveyed on the belt conveyor 3 at the foremost part A magnetic separator 9 for discharging the reinforcing bars and the like contained in the outside is attached.
[0004]
The crushing device 5 includes a fixed tooth 11 and a moving tooth 12, and in order to drive the moving tooth 12, a hydraulic motor 13, a pulley 14 attached to an output shaft of the hydraulic motor 13, and the moving tooth 12 are attached. The pulley 15 is attached to the eccentric shaft and the V belt 16 is wound around the pulleys 14 and 15.
[0005]
In the self-propelled crusher, the object 12 is crushed between the moving tooth 12 and the fixed tooth 11 by moving the moving tooth 12 in the front-rear direction by the hydraulic motor 13. The crushed raw material is conveyed 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 to the outside.
[0006]
On the other hand, as shown in FIG. 7, the self-propelled shredder has a traveling body 2 and a belt conveyor 3 attached to the lower portion of the main body 1 in the same manner as described above, and the power unit 4 is mounted on the rear portion on the main body 1. 1. A hydraulic motor 18 for mounting a crushing device (shredder) 10 for shearing an object to be crushed and a hopper 17 at a front portion of 1 and driving a crushing roller 20 forming a pair of the crushing device 10 in the middle portion of the main body 1. The controller 19 is mounted.
[0007]
The crushing roller 20 of the crushing device 10 for the self-propelled shredder is provided with a plurality of cutting blades on the outer peripheral portion thereof, and the rotation shafts are rotated in the opposite directions so as to draw the object to be crushed between them. It is comprised and crushes by the shear between adjacent blades. The raw material sheared by the shredder is discharged out of the machine by the belt conveyor 3.
[0008]
[Problems to be solved by the invention]
In the self-propelled crusher shown in FIG. 6, the distance between the hydraulic motor 13 that drives the crusher 5 and the pulley 15 on the crusher 5 side is the V belt 16 between the pulley 14 of the hydraulic motor 13 and the pulley 15. It is almost determined by the sandwiching angle. The sandwiching angle of the V-belt 16 greatly affects the 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 crushing device 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.
[0009]
On the other hand, in the self-propelled shredder shown in FIG. 7, since the shredder 10 and the hydraulic motor 18 that drives the shredder 10 are integrated, the hydraulic motor 18 is slightly more than the center of the main body 1 in order to maintain the vehicle weight balance. Mounted on the back.
[0010]
As described above, the positions of the hydraulic motors 13 and 18 vary depending on the crushing device to be mounted, and therefore the arrangement of the pipes for supplying the pressure oil for driving the motors is different. Moreover, the connection and connection of the main-body part 1 and the crushing apparatuses 5 and 10 are performed with the volt | bolt and the nut.
[0011]
As described above, conventional self-propelled crushers have multiple models such as self-propelled crushers and self-propelled shredders depending on the object to be crushed. There is no configuration in which only the devices 5 and 16 can be easily replaced. For this reason, the user must purchase a self-propelled crusher suitable for the raw material, increasing the economic burden on the user.
[0012]
The present invention has been made in view of the above problems, and an object of the present invention is to realize a self-propelled crusher having a configuration capable of providing a crusher having a crushing device corresponding to various objects to be crushed with less economic burden. To do.
