Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a scraping device for a flight conveyor that conveys highly adhesive substances such as sludge.

Conventionally, for example, sludge has been transported as shown in FIG.

Reference numeral 1 denotes a main body of the conveying section, in which a flight conveyor 2 is provided.

The flight conveyor 2 transfers sludge introduced from the sludge supply ports 3, 3 to the left or right.

On the other hand, below the transport section main body 1, a plurality of hopper parts 4a to 4d are provided in parallel in the transport direction.

The sludge transferred by the rotation of the flight conveyor 2 is sequentially stored in a portion of one of the hoppers through the openings 5a to 5d.

In this case, arbitrary gates (not shown) are provided in the openings 5a to 5d, and by controlling them,
The storage state mentioned above is controlled.

However, in this case, as shown in the diagram, the flight conveyor 2
There is a drawback that sludge adheres to the flight 2a and prevents it from falling naturally.

Therefore, a scraping device is absolutely necessary, but if this scraping device is provided in the intermediate portion, it will actually become an obstacle to transport when a part of the hopper is changed.

This invention was made to eliminate these drawbacks, and by providing a scraping part at the opening of each hopper that protrudes and sinks in response to the opening and closing of the gate, it is possible to reliably scrape off the substances adhering to the flights. To provide a scraping device for a flight conveyor that can be removed and does not become an obstacle during transfer.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG.

2 is a flight conveyor, and 2a indicates its flight.

A hopper portion 4 is provided below the flight conveyor 2 in the same manner as in the prior art.

A gate 7 that is opened and closed by a cylinder 6 is provided at the upper end of the upper opening 5 of the hopper part 4.

Therefore, by opening and closing this gate 7, the transfer path 8 of the transfer section main body 1 is communicated with the hopper part 4.

The lower surface of the gate 7 is provided with a tapered portion 12a that operates an operating lever 12, which will be described later.

On the other hand, a hook-shaped arm 9 is fixed to the frame on the side of the opening 5 of the hopper part 4, and an operating lever 12 is rotatably supported on the upper end of the arm 9.

The tip of the operating lever 12 is inserted into the opening 5 of the hopper part 4 through the sulin l-12b and pivotally supports the scraping arm 13, and has a balance weight 14 at the rear end. The scraping arm 13 is normally urged upward.

At the same time, a pressing piece 15 is provided in the middle part, and a roller 16 is pivotally attached to the tip thereof, and when the gate I is closed, this roller 16 is pressed by the tapered surface of the tapered part 12a, so that the actuating lever 12 is tilted to the state shown by the imaginary line, and the scraping arm 13 is eventually lowered to the state shown by the phantom line.

Therefore, when the gate 7 is closed, the scraping arm 13 is completely housed within the opening 5.

On the other hand, the scraping arm 13 has a rectangular ring-shaped scraping piece 11 fixed to its upper end with the upper side arched, and a return weight 18 is provided at its lower end, so that it is normally supported vertically.

Therefore, when the flight 2a on which the sludge 19 is attached approaches, for example, in the state shown by the solid line in the figure, it eventually engages with the scraping piece 17 and is scraped off.

After that, the scraping arm 13 is rotated to the illustrated position A by the movement of the flight 2a, and after passing the flight 2a, it returns to its original position again by the action of the return weight 18.

This operation is repeated several times to complete the supply of sludge to the hopper.

These operations are exactly the same even when the transport direction of the flight conveyor 2 is reversed.

As described above, according to the present invention, since the scraping part that protrudes and sinks in response to opening and closing of the gate is provided in the opening of a part of each hopper, it is possible to reliably scrape off substances attached to the flights, and during transfer. It does not become an obstacle.

Therefore, stable distributed transportation is possible.

In addition, in the above description, although sludge was illustrated as an adhesive substance, it is not limited to sludge, and various substances can be targeted.
