A crusher (crushing device) 30 for crushing the rock received from 0 is loaded, and the output of the diesel engine 4 is driven by the hydraulic pump 6 and the hydraulic motor 7 via the rotary shaft 4 a and the chain wheel 5. The crusher 30 is shown in FIG.
As shown in the figure, a jaw crusher is used between a fixed crushing plate 35 and a movable crushing plate 36 swinging back and forth, and a rock, which is a material to be crushed, is injected and crushed. And the movable crush plate 36 is swung via the eccentric rotation shaft 33. The crushed crushed product is discharged from the discharge path 30A to the outside of the machine by the belt conveyor 40, and is transferred by the subsequent belt conveyor or another transport machine. 8 is an operator room. Reference numeral 9 denotes a cover which is located at a rear portion of the operator room 8 and collectively covers each device on the frame 3 such as the crusher 30, the diesel engine 4, the hydraulic pump 6, and the hydraulic motor 7.

[0003]

In the above-mentioned conventional mobile crusher, rock is thrown in by a hopper 10 by a shovel loader, dropped in the hopper 10 by its own weight, and introduced into the crusher 30. ing.

At this time, depending on the size and amount of the rock introduced into the hopper 10, the clogging of the rock may occur in the hopper 10 and it may be difficult for the rock to be sent to the crusher 30. Further, when a rock having a size or an amount exceeding the crushing ability of the crusher 30 is thrown in, or a foreign matter (for example, a piece of wood, a reinforcing bar, or the like) that is difficult or impossible to crush is mixed and crushing is hindered, the crusher 30 is damaged.
Must be stopped to remove the foreign matter from inside the crusher 30.

[0005] Further, for example, in the crusher 30, rocks mesh with each other with a certain time signature, and do not happen to be crushed by the relative movement of the fixed / movable crushing plates 35, 36, but merely lift up between the crushing plates 35, 36. In some cases (a so-called bridge state).
In such a case, after temporarily stopping the crusher 30,
Generally, an operator applies an impact such as a work tool to the engaged rock to restore the crushing ability of the crusher 30.

[0006] In order to promptly take the above measures,
During the crushing operation, the presence or absence of clogging of the rock in the hopper 10, the feeding state, the crushing state of the crusher 30 and the like are constantly monitored, and when the above-mentioned situation occurs, the charging to the hopper 10 is immediately stopped or the crusher 30 is stopped. It is necessary to take measures such as stopping.

However, in the conventional mobile crusher 1, the rear part of the operator room 8 is covered by the cover 9, and only the upper part of the hopper 10 projects outside the cover 9. Therefore, crusher 30
The vicinity of the connection portion to the crusher 30 at the lower portion of the hopper 10 is covered with the cover 9, and it is difficult to visually check the inside of the hopper 10 and the crushing state of the crusher 30 during the crushing operation.

[0008] A first object of the present invention is to provide a self-propelled crusher capable of easily visually checking the crushing state of a crushing device during a crushing operation.

A second object of the present invention is to provide a self-propelled crusher which can easily visually confirm the condition inside the hopper during crushing operation.

In order to achieve the first object described above, a self-propelled crusher of the present invention comprises a frame, a traveling means provided on the frame, and a crushed object received by the hopper. A hopper for receiving an object, a crushing device for crushing the object to be crushed, and an inspection landing provided at least on one side in the longitudinal direction of the frame and capable of monitoring at least the crushing device. In the present invention, by providing the inspection landing, the worker always stands at this landing during the work, so that at least the operating state of the crushing device can be easily monitored and visually inspected.
Therefore, for example, when a crushed object having a size or an amount exceeding the crushing capacity of the crushing device is thrown in from the hopper, or a non-crushable foreign matter is mixed, and clogging or crushing trouble occurs in the crushing device. When a so-called bridging state occurs, it can be easily and immediately found visually. This makes it possible to quickly take measures such as stopping charging into the hopper and stopping the crusher.

Preferably, in order to achieve the first and second objects, the inspection landing is configured to monitor the inside of the hopper. This allows the worker to stand on the landing and easily monitor and inspect the state inside the hopper by visual confirmation. Therefore, for example, when the crushed object put into the hopper is too large or too large and the crushed object is clogged in the hopper, it can be immediately and easily found visually. This makes it possible to quickly take measures such as stopping the charging to the hopper.

[0012] More preferably, there is further provided a feeder provided between the hopper and the crushing device, for conveying the object to be crushed received by the hopper to the crushing device. The feeder is configured to be monitored.
