Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is to put dust collected by a garbage collection vehicle into a pit for temporarily storing dust supplied to a processing device such as a crusher. The present invention relates to a dust throwing device.

[Conventional technology]

For example, as shown in FIG. 4, the processing equipment using a crusher is provided with a conveyor 2 in the length direction on the bottom surface of a dust storage pit 1 having an inverted trapezoidal cross section. It is configured to be sent to the crusher 3.

In this equipment, as described in Japanese Utility Model Publication No. 1-204004, a front edge of a damping box 4 is rotatably attached to an upper edge of a pit 1, and the box 4 can be tilted by a hydraulic cylinder. This box 4
The garbage truck A is moved in and out of the box, and the dust is put into the pit 1 directly from the box 4, or the dust is put into the box 4 to remove dangerous substances such as a gas cylinder, and then the box 4 is tilted. , There is a device to put in the pit 1.

[Problems to be solved by the device]

In this dust throwing device, the lower side of the damping box 4 is a hole of the platform 5, and the fall prevention means into the hole may be provided with a screen on the side platform 5 from its side surface side. A partition cannot be provided on the approaching side of the dust collecting vehicle A, that is, on the trailing edge side of the box 4.

Therefore, when the box 4 is tilted, a worker may fall from the platform 5 on the trailing edge side of the box 4 into the hole. The dust collection vehicle A is normally moved in and out of the damping box 4, and if it enters without checking the tilting of the box, it may fall into the hole. This is likely to occur in the initial stage of the tilting motion.

An object of this invention is to prevent falling into the hole.

[Means for Solving the Problems]

In order to solve the above problems, in the present invention, as described above, the damping plate is provided between the platform and the dust storage pit, and the front end of the damping plate is rotated to the upper edge of the dust storage pit. It is supported freely and can be tilted up and down by the driving means, and its rear end can be connected to the platform in a horizontal state, and dust can be collected from the platform to the damping plate via the rear end continuous portion. In the dust throwing device to the dust storage pit where cars go in and out, a vertical shutter is provided at the continuous portion of the platform, and this shutter is movable below the continuous portion of the platform, and the wire from the lower end of the shutter is movable. , The above-mentioned damper pin through the fixed pulley above the required distance The shutter is retracted from the upper surface of the continuous portion of the platform when the damper plate is connected and the damping plate is in the horizontal state.

The fixed pulley moves the wire up and down along the shutter to move the shutter up and down, and its position (predetermined length) is higher (longer) than the moving distance of the shutter.

[Action]

In the dust throwing device configured in this manner, the shutter is retracted when the damping plate is in a horizontal state. To do.

When the dumping is completed and the damping plate is tilted, the shutter projects above the damping plate continuous portion via the wire in accordance with this movement. For this reason,
This shutter prevents the dust collecting vehicle from entering the damping plate and from falling below the damping plate tilted from the continuous portion by the worker.

〔Example〕

This embodiment is provided in the dust treatment facility shown in FIG. 4 described above, and as shown in FIGS. 1 and 2, a damping box 10 is provided between the platform 5 and the dust storage pit 1. The front end of the box 10 is rotatably supported by the upper edge of the pit 1 and can be tilted up and down by a hydraulic cylinder 11, and the rear end thereof continues to the platform 5 in a horizontal state.

Vertical guides 12 having a U-shaped cross section are provided on both sides below the continuous portion so as to be supported by the frame F.
A shutter 13 is movably fitted between the guides 12, 12. A wire 14 is led out from both sides of the lower end of the shutter 13, and the wire 14 is fixed pulley above the lower end.
It is fixed to the lower surface of the damping box 10 through a fixed pulley 16 at the same level as the pulley 15 and its pulley 15, and when the box 10 inclines as shown by the chain line in FIG. Project above the continuous portion to prevent the garbage truck from entering and exiting. Box 10
When is returned to the horizontal state, the shutter 13 descends due to its own weight, and the garbage truck can enter and leave.

It should be noted that the shutter 13 does not have to be plate-shaped, but a plurality of parallel rod-shaped,
Any shape, such as a lattice shape, that can prevent entry and exit can be used. Further, the damping box 10 may be a plate having only a bottom plate.

[Effect of device]

This invention is configured as described above, and the shutter is moved in conjunction with the movement of the damping plate (damping box) to prevent the dust collecting vehicle and the worker from falling below the tilted damping plate. It has the effect of ensuring safety.
