  The main panel 61 and the entry panel 62 are formed of a lattice frame material and a mesh material applied to the frame material. The entry panel 62 has a triangular projecting inclined portion 62A protruding at both ends thereof. The wheels of the carry-in vehicle 2 that enters while making a turn ride on the slope 11 via the overhanging inclined portion 62A. Thereby, the turning radius of the carrying-in vehicle 2 moving backward can be reduced.

  The main panel 61 is grounded on the platform 1 via a plurality of end side support legs 64 and a plurality of intermediate support legs 65. Each end side support leg 64 is disposed in the vicinity of the rotation center axis of the slope 11 on which the support pin 12 is provided. Each intermediate support leg 65 is disposed in the vicinity of the rotation center axis of the slope 11 on which the hinge pin 63 is provided.

  The hole 54 through which the support pin 12 of the slope mounting bracket 51 is inserted is formed in a long hole shape extending in the vertical direction. Accordingly, the base end portion of the main panel 61 can be displaced in the vertical direction corresponding to the undulations (unevenness) of the platform 1.

  A lower end portion of the actuator 13 is rotatably connected to the main panel 61 via a support pin 55. In a state where the upper end portion of the actuator 13 is connected to the actuator mounting bracket 53 via the support pin 52, the slope 11 rotates around the support pin 12 as the actuator 13 expands and contracts.

  As a configuration in which the attachment position of the slope 11 is changed, a hydraulic hose (not shown) that supplies and discharges hydraulic oil guided from the hydraulic unit is detachably connected to the actuator 13. As shown in FIG. 4, as the actuator 13 contracts from the state in which the slope 11 is deployed, the slope 11 rotates upward with the support pin 12 as a fulcrum, and is held in the retracted position extending in the vertical direction. The On the contrary, as the actuator 13 is extended from this retracted position, the slope 11 is rotated downward with the support pin 12 as a fulcrum, and is grounded to the platform 1.

  As described above, the slope 11 attached to the slope attachment portion 15 on the left side develops so as to extend to the left side of the conveyor extension portion 20E. On the other hand, the slope attachment portion 16 on the right side has the same configuration as the slope attachment portion 15 described above. The slope 11 attached to the slope attachment portion 16 on the right side develops so as to extend to the right side of the conveyor extension portion 20E.

  The inspection work of the carry-in is performed according to the following procedure.

  The inspection conveyor 6 is moved to the front side of the processing pit 4 so that the front end folding portion 20C of the conveyor 20 faces the processing pit 4.

  -Unfold the slope 11 from the left side of the inspection carrier 6. The slope 11 attached to the slope attachment portion 15 on the left side extends to the left side of the conveyor extension portion 20E.

  The incoming vehicle 2 is moved rearward and in the right direction (Y-axis direction), stopped at the position on the slope 11, and the discharge portion of the incoming vehicle 2 is made to face the conveyor 20 of the inspection transporter 6.

  At this time, since the slope 11 extends in a direction (Y-axis direction) orthogonal to the circulation direction (X-axis direction) of the conveyor 20, a path through which the incoming vehicle 2 enters the inspection transporter 6 is indicated by an arrow in FIG. As indicated by A, the processing pit 4 is formed in a straight line extending in parallel with the gate 5. Thereby, when the approach route of the incoming vehicle 2 is taken in a direction parallel to the gate 5 of the processing pit 4, it is not necessary for the incoming vehicle 2 to turn in front of the slope 11, as indicated by an arrow B in FIG. The space required for the carry-in vehicle 2 to enter the inspection carrier 6 does not have to be large.

  On the other hand, when the approach path of the carry-in vehicle 2 is secured on the right side of the inspection transporter 6, the slope 11 is replaced with the slope mounting portion 16 on the right side, and the slope 11 is on the right side of the conveyor extension portion 20E. Expanded to extend.

  Since the attachment position of the slope 11 can be changed to the left side or the right side of the inspection transporter 6, it is possible to switch the route in which the incoming vehicle 2 enters the inspection transporter 6 in accordance with the space of the waste disposal factory.

  However, the present invention is not limited to this, and a slope attaching portion to which the slope 11 is attached may be provided at the rear portion of the inspection transport machine 6.

  -A loading thing is dropped on the conveyor 20 from the discharge part of the carrying-in vehicle 2, and the inspection work of a loading thing is performed on the conveyor 20. FIG.

  When this inspection work is finished, the conveyor 20 is circulated, and the load on the conveyor 20 is carried out to the processing pit 4.

  -When the said inspection work is complete | finished, the expand | deployed slope 11 is stored, the conveyance machine 6 for an inspection is made to self-propel and it removes. As a result, a normal carrying-in operation is performed in which the carrying-in vehicle 2 enters the front of the processing pit 4 and directly drops the loaded material from the discharge unit of the carrying-in vehicle 2 into the processing pit 4. As a result, the operating rate of the processing pit 4 can be increased in the waste processing factory.

  (C) The slope attaching portions 15 and 16 are provided on the side portions of the main body frame 57, and the slope 11 is attached so as to extend in a direction (Y axis direction) orthogonal to the circulation direction (X axis direction) of the conveyor 20. And

  Based on the above configuration, the route for the incoming vehicle 2 to ride on the slope 11 and enter the inspection transporter 6 is arranged in parallel with the gate 5 of the processing pit 4 arranged in the waste disposal plant, and the incoming vehicle 2 enters. The required space can be reduced in the circulation direction (X-axis direction) of the conveyor 20.

  (D) The slope mounting portions 15 and 16 are provided side by side behind the traveling device 14, and the traveling device 14 is disposed in front of the center of gravity G of the conveyor 20, and supports the main body frame 57 by rolling on the platform 1. The caster 17 to be arranged is arranged behind the conveyor 20.

  Based on the said structure, the slope 11 is not arrange | positioned above the traveling apparatus 14, the installation height of the slope 11 is restrained low, and the approach of the carrying-in vehicle 2 is performed smoothly.

  And since the weight concerning the rear part of the conveyor 20 is supported by the caster 17, it arrange | positions the traveling apparatus 14 in the front part of the conveyor 20 so that it may not interfere with the slope 11, and the rear part of the conveyor 20 does not contact the platform 1. You can do both.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.
