  The operation, operation, and effect of the present embodiment configured as described above will be described.

  During the operation of the sieving device 3, when the object to be sorted is thrown into the loading part 55 of the sieving device 3 by, for example, a loading heavy machine such as a hydraulic excavator, a recycling machine, a belt conveyor, or the like, It passes through the sieve member and is guided onto the transport surface of the discharge conveyor 2, transported forward by the discharge conveyor 2, and discharged forward of the machine body. On the other hand, those larger than the selected particle size descend on the sieve member and are discharged to the rear of the machine body.

  In such a self-propelled vibrating screen, a maintenance work (cleaning) such as removal of earth and sand treated objects adhering to the input portion 55 (hopper 47, sieve member, etc.) or removal of clogged objects to be treated is performed. Work) is necessary. However, in the self-propelled vibrating screen of the prior art, since there is no place for hooking the work safety belt around the input part, the worker cannot enter the input part and perform maintenance work. It was necessary to perform maintenance work using tools from a conveyor with stop control for work or from the top of a pile of processed objects built on the side of the machine. Therefore, there is a problem that there is a part that cannot be reached from the position of the worker or that maintenance of details is difficult, and workability is remarkably deteriorated.

  On the other hand, in the present embodiment, a plurality of vertical strut members 103 and 104 are provided upright on the outer periphery of the insertion portion 55 into which the object to be processed processed by the processing apparatus is input from the outside of the machine body, Since the plurality of vertical strut members 103 and 104 are connected by the horizontal connection member 105 capable of hooking the work safety belt above the outer edge portion of the input portion 55, the operator works on the horizontal connection member 105. Maintenance work can be performed by entering into the charging unit 55 with the hook of the safety belt hooked, and therefore the workability of the maintenance work of the charging unit 55 in the self-propelled processing machine can be improved.

  In addition, since the vertical strut members 103 and 104 are extracted from the holding members 101 and 102 and can be stored from the top of the sieve device 3 (that is, on the input unit 55), this hinders work during the processing operation of the workpiece. It can be suppressed.

  Furthermore, since the work safety belt hooking device 100 (that is, the holding members 101 and 102) at the time of storage is stored within the range of the transport limit width and the transport limit height, it prevents the hull transportation from being hindered. be able to.
