BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hopper device for a processing vehicle equipped with a device for crushing empty containers such as empty bottles and other processes.

[0002]

2. Description of the Related Art Conventionally, as devices for crushing empty bottles and the like are disclosed in JP-A-2-4483, JP-A-3-118848 and the like. A carry-in conveyor that lifts and carries the empty bottles and the like to the input port of the above-described apparatus, a hopper that stores the processed waste and a transfer conveyor that transports the waste from the processing device to the hopper, and the like on the vehicle body of the traveling vehicle. Mounted processing vehicles are known.

[0003]

However, in the conventional processing vehicle, in order to discharge the processing waste from the rear of the hopper, the hopper is disposed at a position in front of or at the side of a carry-in conveyor for lifting and carrying empty containers from the rear of the vehicle. Installation space required installation space for the conveyor and hopper installation space on the car body, and the space on the car body was narrow, and there was little space for other equipment to be installed. . In order to eliminate these inconveniences, it is necessary to reduce the size of conveyors and hoppers, and it is necessary to keep the overall processing capacity low, which greatly restricts the duration of work and the regional size of processing. There was a problem.

[0004]

The hopper device according to the present invention for solving the above-mentioned problems inclines so that the terminal side rises on the vehicle body 2 and lifts and loads the empty container 13 toward the processing section. When the carry-in conveyor 11 is installed, the carry-in conveyor 1 is located below the carry-in conveyor 11.
A transfer conveyor 19 for lifting and transferring the processing waste of the empty container 13 by inclining in a direction opposite to that of the transfer conveyor 1 is provided.
The apparatus is characterized in that processing waste transferred to a mountain-shaped space surrounded by the transfer conveyor 1 and the transfer conveyor 19 is accommodated, and a hopper 22 having a trapezoidal shape is installed along the space.

[0005]

The empty container 13 carried in by the carry-in conveyor 11 is processed by a processing machine such as a crusher 18 and the processing waste is transferred to the hopper 22 by the transfer conveyor 19 and stored therein. The processing waste is finally discarded or transferred from the vehicle body 2 to the outside. Since the transfer conveyor 19 is located below the carry-in conveyor 11 so as to overlap with the carry-in conveyor 11, the installation space on the vehicle body 2 can be shared. In addition, the hopper 22 moves along the trapezoidal space 21 surrounded by the conveyors 11 and 19. Since it is formed, the size is increased without occupying a useless space, and the installation space and working space for other devices can be widened.
