In many cases, crushed materials are processed. Therefore, it is necessary to make it easy to check the transport state of the crushed material and to remove the clogged one. However, in the device described in Patent Literature 1, the crushing device is the jaw crusher 53, and the crushed material is rock or reinforced concrete, and is hardly clogged. Further, the crushed material is fine (it is difficult to form an expansion string). An opening 57 having a small opening area (low height) is provided only below the jaw crusher 53. Accordingly, in the case of the twin-shaft shearing crusher, when an opening is provided only below the crusher, it is difficult to remove the crushed material when a large amount of clogging occurs during the conveyance.
(2) In recent years, in a two-shaft shearing type crusher, crushed materials have been discharged to the rear of the vehicle (the power source chamber 65 side in FIG. 5) for convenience of operation. Therefore, the transport distance of the belt conveyor passing between the left and right side plates 66, 66 becomes long, and it is very difficult to inspect and clean the vehicle from the front and rear direction of the vehicle via the space above the belt conveyor as disclosed in Patent Document 2. Difficult.

The present invention has been made in view of the above problems, and has a biaxial shearing type in which crushed materials are transported by a conveyor to a power source side arranged in line with a biaxial shearing type crushing device. It is an object of the present invention to provide a twin-screw type crusher that can easily check for entanglement or clogging of crushed material on the conveyor and remove the crushed material.
[0011]
Means for Solving the Problems, Functions and Effects
In order to achieve the above object, a first invention is directed to a biaxial shearing crusher, which comprises a frame, a biaxial shearing crushing device mounted in a row in the longitudinal direction of the frame, and a power source therefor. It is provided with a shaft shearing type crushing device and a belt conveyor for transferring crushed material disposed below the power source thereof, and has a configuration in which inspection ports are provided at different positions along the flow direction of the belt conveyor.
[0012]

According to a second aspect of the present invention, in the first aspect, the inspection port is provided at least below the two-axis shearing type crushing device or the driving device and at a vehicle body outlet of the belt conveyor.
[0014]
According to the second invention, it is possible to easily inspect the lower part of the two-axis shear crushing device or the driving device, which is most likely to be clogged when the crushed material is conveyed by the belt conveyor, and the vehicle body exit portion of the belt conveyor. The object can be efficiently removed, and the operation can proceed smoothly.
[0015]
In a third aspect based on the first or second aspect, the upper surface of the frame on which the power source is mounted is higher than the upper surface of the frame on which the biaxial shearing crusher is mounted.
[0016]
According to the third invention, since the upper surface of the frame on the power source mounting side is higher than the biaxial shear type crusher mounting side, an inspection port having a large vertical dimension can be provided in this portion. Therefore, the inspection work and the removal work when the crushed material is clogged can be easily performed, and the work efficiency can be improved.
