BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled construction waste material crusher for crushing construction waste materials such as concrete waste and asphalt waste.

[0002]

2. Description of the Related Art As an example of a prior art of a self-propelled construction waste material crusher (not shown), a main vehicle body is connected to an upper portion of a crawler traveling body, and concrete trash is provided on an upper front side of the main vehicle body. It has a hopper that receives construction waste such as, and also has horizontal horizontal spindles with flywheels and large pulleys attached to both left and right ends, and a crusher that performs a crushing operation by rotation of the spindle is provided on the main body. The construction waste material supplied to the hopper is fed into the crusher by the feeder from the discharge port at the bottom of the hopper, and is crushed into predetermined fine particles.

[0003]

In the prior art self-propelled construction waste material crushing machine, there are one in which the upper side of the main shaft of the crusher is covered with a flat plate cover and the other in which the crusher is opened without a cover. . Therefore, in both cases, an operation to adjust the clogging of the crushed material at the discharge port at the bottom of the hopper,
It was difficult to visually check the feeding condition of the feeder and the crushing condition of the crusher. It is an object of the present invention to provide a step structure that can solve the above problems.

[0004]

It has a horizontal horizontal spindle with a flywheel and a large pulley attached to it, and a crusher that performs a crushing operation by rotation of the spindle is installed on the main body, and the construction waste supplied to the hopper is discharged from the bottom of the hopper. In a self-propelled construction waste material crusher that feeds to the crusher with a feeder and crushes it to a predetermined fine grain, near the upper side of the crusher main shaft, at a position between the left and right flywheels and the large pulley, A step-like step was formed in which the upper part of the rear side of the main body was lifted toward the hopper. Then, a pair of side plates is fixedly attached to the left and right end surface portions of the stepped step, respectively, and a part of each of the lower end edges of the pair of side plates is provided with an upper end portion of each of the left and right bearings supporting the main shaft of the crusher. I placed it on. Further, the lower end edge of the above step and the main vehicle body are connected to each other via a hinge member so that the entire step can be rotated in the front-rear direction. Alternatively, a multi-step step among the step-like steps is formed separately from the step body, the multi-step step portion and the step body are connected via a hinge member, and the multi-step step portion is rotated in the front-rear direction. Made possible In addition, a flywheel and a cover that covers the upper side of the large pulley are provided above the pair of left and right side plates.

[0005]

In the present invention, since a step-like step which rises from the upper surface of the rear side of the main body toward the hopper is formed, the worker climbs up the step to crush the crushed material at the discharge port at the bottom of the hopper. It is possible to easily perform the operation of adjusting the clogging of the material and the visual confirmation of the feeding status of the feeder and the crushing status of the crusher. Also, a pair of side plates are fixedly attached to the left and right end surface portions of the stepped step, respectively, and a part of each of the lower end edges of the pair of side plates is provided with an upper end portion of each of the left and right bearings supporting the main shaft of the crusher. Since it is placed on the vehicle, the step can be stably installed on the main vehicle body. In addition, the lower end of the step and the main vehicle body are connected via a hinge member so that the entire step can be rotated in the front-rear direction.
Alternatively, among the stepped steps, a plurality of steps are formed separately from the step body, and the plurality of steps are connected to the step body via a hinge member, and the plurality of steps can be rotated in the front-rear direction. Therefore, when each part of the crusher arranged below the step is adjusted or inspected, the entire step or the multi-step steps can be pivotally released to perform the maintenance work. Further, since the flywheel and the cover portion that covers the upper side of the large pulley are provided on the upper portions of the pair of left and right side plates, the operator can secure the safety of the flywheel and the large pulley by setting the side plate and the cover portion. .

According to the prior art self-propelled construction waste material crusher,
In some cases, the upper side of the crusher main shaft is covered with a flat plate cover, and in other cases, the crusher is opened without a cover. For this reason, it is difficult to visually check the operation of adjusting the clogging of the material to be crushed at the discharge port at the bottom of the hopper, the feeding status of the feeder, and the crushing status of the crusher. However, in the present invention, since a step-like step that rises from the upper surface of the rear side of the main body toward the hopper is formed, the worker can move up the step to break the crushed material at the discharge port at the bottom of the hopper. It is possible to easily perform the operation for adjusting the clogging of the paper and the visual confirmation of the feeding status of the feeder and the crushing status of the crusher. Also, a pair of side plates are fixedly attached to the left and right end surface portions of the stepped step, respectively, and a part of each of the lower end edges of the pair of side plates is provided with an upper end portion of each of the left and right bearings supporting the main shaft of the crusher. Since it is mounted on the vehicle, the steps can be stably arranged with respect to the main vehicle body. In addition, the lower end of the step and the main vehicle body are connected via a hinge member so that the entire step can be rotated in the front-rear direction, or a plurality of steps among the step-like steps are formed separately from the step body. However, since the multi-step step portion and the step body are connected via a hinge member, and the multi-step step portion is rotatable in the front-rear direction, adjustment and inspection of each part of the crusher arranged below the step is performed. When performing the above, the maintenance work can be performed by rotating and opening the entire steps or the step portions. Further, since the flywheel and the cover portion that covers the upper side of the large pulley are provided on the upper portions of the pair of left and right side plates, the operator can secure the safety of the flywheel and the large pulley by setting the side plate and the cover portion. . Therefore, in the self-propelled construction waste material crusher equipped with the steps of the present invention, it is possible to ensure the safety of the worker with respect to the left and right flywheels, the large pulley and the crusher, and to adjust the clogging of the construction waste material at the discharge port under the hopper. Operation and visual confirmation of the feeder feeding condition and crusher crushing condition, and maintenance work such as adjustment and inspection of each part of the crusher located below the step can be performed easily. it can.
