DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inspecting a crusher, which is capable of externally monitoring the crushing state of the crusher.

[0002]

2. Description of the Related Art Conventionally, an inspection port is opened above a crusher and a monitoring camera is arranged above the inspection port so that the crushing state of the crusher and the blocking state of an input port can be monitored by the monitoring camera. An inspection device for a crusher is already known (see Japanese Patent Application Laid-Open No. 57-171450).

[0003]

In the conventional inspection apparatus for a crusher, an inspection port is opened on an upper surface of an inlet cover at an upper portion of the crusher, and a monitoring camera is disposed above the inspection port to perform the crushing process. Even if crushed pieces are repelled in all directions by the hammer group, surveillance cameras may be damaged by the crushed pieces,
It is configured not to be damaged.

However, even with this configuration, it is difficult to completely prevent the surveillance camera from interfering with the crushed pieces, and the mounting position of the surveillance camera with respect to the crusher is naturally limited. In addition, there is a problem that it is difficult to mount the monitoring camera at an optimum position.

Therefore, in order to solve the above-mentioned inconvenience, it is conceivable to provide a see-through plate at the inspection port. However, even in this case, the see-through plate is contaminated by dust or the like or interferes with crushed pieces. Another problem is that it must be replaced frequently because it is damaged, and the workability deteriorates.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a new inspection device for a crusher capable of solving all of the above problems.

Is provided with a movable see-through plate, the see-through plate has a plurality of see-through portions that can correspond to the inspection port at a plurality of positions, and the see-through portion can be changed to the above-described check port sequentially to cope therewith. In this way, it is characterized in that the movement is adjusted, and according to such a feature, it is easy to change the see-through portion of the see-through plate corresponding to the inspection port,
It can be easily performed, eliminating the need for frequent replacement of the see-through board, and increasing the degree of freedom of mounting the surveillance camera on the crusher. As a result, the surveillance camera always checks the inside of the crusher. As a result, the crushing efficiency of the crusher can be greatly improved.

According to a second aspect of the present invention, in order to achieve the above object, in the first aspect, the see-through plate slides on a straight line.
The plurality of transparent portions are characterized in that they can be sequentially moved and adjusted to a position corresponding to the inspection port,
According to this feature, in addition to providing the above-described effects, it is easy for the see-through portion of the see-through plate to correspond to the inspection port.

Further, according to the third aspect of the present invention, in order to achieve the above object, in the first aspect, the see-through plate is rotated so that the plurality of see-through portions are formed by the plurality of see-through portions. It is characterized in that it can be sequentially moved and adjusted to a position corresponding to the inspection port, and according to such a feature, in addition to the above effect, it is easy for the transparent portion of the see-through plate to correspond to the inspection port. .
