Self-propelled crushing machines are used to improve the cost and reduce costs. FIG. 8 shows a side view of an example of the self-propelled crushing machine 1. The self-propelled crushing machine 1 includes a feeder 2, a crusher 3, a transporter 4, a traveling device 5, a power source 6, and a hopper 7. The material to be crushed, which has been put into the hopper 7 by an unillustrated excavator or the like, is conveyed to the crusher 3 by the feeder 2, crushed by the crusher 3, falls down, and is discharged by the conveyor 4. In addition, the transporter 4 is installed from between the left and right traveling devices 5 and 5 near the ground surface to the upper front. Feeder 2 by power source 6 such as engine,
The crusher 3, the transporter 4, and the traveling device 5 are driven, and move between sites by the traveling device 5.

[0003] The transporter 4 of the mobile crushing machine 1 as described above.
The crushed material discharged in the above is often piled up once in a predetermined place. At this time, it is necessary to increase the height of the leading end of the transporter 4 as much as possible in order to stack as much as possible at the stacking place in terms of work efficiency. Also, when the piled crushed materials are scraped by an excavator and loaded into a truck or the like, the height of the tip of the transporter 4 should be as high as possible so as not to hinder the work of the excavator. Good. On the other hand, in order to prevent the crushed material placed on the transporter 4 and being transported obliquely upward from sliding down,
There is a limit to the installation angle of the conveyor 4 from the horizontal. For this reason, in order to raise the tip position of the transporter 4, a long transporter 4 is required.

However, when the self-propelled crushing machine 1 is transported and transported by a trailer or the like, the height and length are restricted by the Road Traffic Law, so that the transporter 4 needs to be shortened during transportation. The technology to solve this is Utility Model Registration No. 260

Payout conveyor 1 in working posture
The procedure for changing 0 to the storage position will be described. First, the conveyor elevator 24 is rewound to loosen the conveyor undulating wire 25. Then, the payout conveyor 10 rotates and descends around the hinge portion 18 until it becomes horizontal. Further, the conveyor hoisting wire 25 is slackened by rewinding the conveyor elevator 24, and the intermediate portion of the wire 25 is passed through the storage wire locking portion 23. Next, when the conveyor elevator 24 is involved, the payout conveyor 10 moves backward while maintaining the horizontal state. Then, when the movement to the final end is completed, thereafter, the payout conveyor 1
The first half of 0 rotates upward, and at the stage when it rotates to a predetermined angle, the storing operation of the payout conveyor 10 is completed.

[0007]

However, the above prior art has the following problems. In order to change the working posture to the storage posture, the conveyor hoisting wire 25 of the conveyor elevator 24 is loosened and the payout conveyor 10 is leveled,
Thereafter, the conveyor hoisting wire 25 is slackened, and the conveyor elevator 24 is temporarily stopped. Then, the conveyor hoisting wire 25 is changed so as to pass through the storage wire locking portion 23, and the conveyor elevator 24 is operated again. This time, the conveyor hoisting wire 25 is taken up and the payout conveyor 10 is moved to the rear of the vehicle body. And rotate upward. In order to change from the storage posture to the work posture, the above procedure is performed in reverse. Thus, the payout conveyor 10
The work procedure to change the posture of the
Since it is complicated over a plurality of steps, it takes a long time to change the attitude, and there is a problem that the attitude of the payout conveyor 10 cannot be easily changed. Furthermore, since it is composed of a plurality of components such as the sliding member 17, the hinge portion 18, the conveyor elevator 24, and the conveyor hoisting wire 25, there is a problem that the structure is complicated and expensive.

An object of the present invention is to provide a crushing apparatus provided with a conveyor storage device which is easy to operate and has few failures, focusing on the above-mentioned problems of the prior art.

[0009]

Means for Solving the Problems, Functions and Effects In order to achieve the above object, a first invention is a crushing apparatus having a crusher and a carrier on a base, wherein the carrier has a discharge end. The crusher is configured to have an inclined portion so as to be higher than the discharge portion of the crusher, and the inclined portion is provided with a moving mechanism of the transporter.

According to the first aspect of the invention, the transfer device has an inclined portion such that the discharge end is higher than the crusher discharge portion, and the inclined portion is provided with a moving mechanism for the transfer device. As a result, the discharge end of the transporter can be retracted toward the vehicle body and positioned lower, so that even if the transport length and / or height of the crusher exceeds the transport regulation value, the transport regulation value can be obtained. You can easily move settings below. Further, since the posture of the transporter can be changed simply by moving the transporter, the operation is simple and the set time is short. Moreover, the structure is simple and inexpensive.

A second invention is based on the first invention, wherein the base is provided with a traveling device, and the moving mechanism of the transporter is provided outside the traveling device.

According to the second invention, the crushing device includes the traveling device, and the moving mechanism of the transporter is provided outside the traveling device. As a result, the moving mechanism is provided not to the inside or the lower part of the vehicle body but to the outside of the traveling device, so that the worker can easily approach the moving mechanism, so that the working posture can be easily changed from the working posture to the stowed posture, and assembly and maintenance can be performed.

As a result, the discharge end of the transporter can be retracted toward the vehicle body and positioned lower, so that even if the transport length and / or height of the crusher exceeds the transport regulation value, the transport regulation value can be obtained. You can easily move settings below. Further, since the posture of the transporter can be changed simply by moving the transporter, the operation is simple and the set time is short. Moreover, the structure is simple and inexpensive. The crushing device includes a traveling device, and the moving mechanism of the transporter is provided outside the traveling device. As a result, the moving mechanism is provided not to the inside or the lower part of the vehicle body but to the outside of the traveling device, so that the worker can easily approach the moving mechanism, so that the working posture can be easily changed from the working posture to the stowed posture, and assembly and maintenance can be performed. A good crusher can be obtained. In addition, the transport device is divided into a plurality of portions and can be bent mutually. Accordingly, when the transport device is changed from the transport position to the storage position, the transport device is bent, and the transport device can be stored more compactly. In addition, since the transporting device is lifted up and brought into close contact with the base by the swing mechanism, there is no possibility that the transporting device will collide with the end of the transporting device and be damaged during transportation. Further, since the rear transfer device is moved up and down by the lifting device, the operator can easily set the height of the transfer device. Thus, in the case of waste concrete containing foreign matter (iron piece or the like), the gap between the base and the transporter can be increased to prevent clogging. Further, at the time of crushing without foreign matter, the gap can be made small to prevent breakage of the unloader (particularly the belt) due to falling of non-crushed material.
