Description

[Detailed Description of the Invention] The present invention relates to an improvement of a device for collecting bulk materials such as coal.

The inventors of the present invention have developed a system that can reliably and quickly collect bulk materials such as coal, is lightweight, and consumes little power. We have developed a device in which a cutting cutter with a number of cutting claws is rotatably attached to the part.

However, a portion of the bulk material scraped by the scraping cutter is caught between the tip of the receiving plate provided at the lower front end of the collection conveyor and the scraping claw, and these receiving plates There was a problem that the raking claws were damaged.

The present invention has been devised to solve the above-mentioned problems, and its purpose is to at least prevent the receiving plate from being damaged when a load of more than a predetermined value is applied to the tip of the receiving plate due to the sandwiching of loose materials. By configuring the tip of the plate to retreat to release the pinching of the bulk material and immediately return to its original state,
To provide a device that can safely and reliably collect bulk materials.

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 is a retaining wall, for example
They are approximately 700 to 800 meters long and are placed in parallel at intervals of approximately 50 meters, between which bulk materials such as coal C are piled up and stored. A rail 2 is laid on the top surface of the retaining wall 1, and a movable beam 3 is placed on top of the rail 2.
is constructed so that it can move in parallel along the retaining wall 1. There are two rails 4 on the top surface of the moving beam 3.
has been laid, and a trolley 5 is mounted on it so that it can run freely. A turning board 6 is rotatably mounted on the truck 5, and a turning motor (not shown) is installed on the truck 5.
This allows it to turn left and right. A sampling device main body 7 is mounted on the turning table 6, and the base of a sampling conveyor arm 8 is pivotally mounted. The collection conveyor arm 8 is also held by lift arms 9a, 9b, and can be raised and raised by respective cylinders.

The collection conveyor arm 8 includes a collection conveyor 10 made of a rubber flexible belt conveyor belt.
is attached, and its upper part is adapted to move in the direction of arrow A in FIG. As is clear from FIGS. 2 and 3, this collection conveyor 10 has partition plates 10a integrally arranged at appropriate intervals, and bellows-shaped side plates 10b integrally formed on both sides of the partition plates 10a. It is structured as follows. This side plate 1
0b, the partition plate 10a is the collection conveyor arm 8.
The bellows spreads out in a fan shape when going around the hanging roll 11 attached to the tip of the bellows.

A scraping cutter 12 having a large number of scraping claws 12a is attached to the front part of the collection conveyor 110, and is rotated by an oil motor 13 in the direction of arrow B in FIG. 3 to remove the piled up coal C. It is designed to be partially broken and scraped into the tip of the collection conveyor 10.

Reference numeral 14 denotes a receiving plate, which is disposed on the lower side of the front end of the collection conveyor 10 along the outside of the movement locus of the tip of the partition plate 10a.
A part of the coal C scraped in by the partition plate 10a is received and scooped out by the partition plate 10a.
The receiving plate 14 is attached to a rotating plate 15 that is pivotally attached to the frame at the tip of the collection conveyor arm 8, and is configured to be able to rotate as shown in phantom lines in FIG. It is always urged by a spring 16 to return to the solid line state.
17 is a stopper.

Since this embodiment is configured as described above, when discharging the piled up coal C,
The moving beam 3 and the cart 5 are moved to appropriate positions, the collection conveyor 10 is raised upwards, and the scraping cutter 12 is set at the upper position of the pile.

Subsequently, the motor 13 is operated to remove the scraping cutter 1.
2 is rotated to scrape the coal C into the front end of the collection conveyor 10. Some of the scraped coal C is taken into the partition plate 10a of the collection conveyor 10, and some of the coal C enters into the receiving plate 14. The coal C that has entered the receiving plate 14 moves from the lower rear side to the partition plate 10a.
It is scooped up and conveyed in the direction of arrow A.

The coal C collected by the collection conveyor 10 and sent to its base is dropped onto a moving beam conveyor 18 provided inside the moving beam 3, and is discharged as appropriate.

As is clear from FIG.
, a part of the coal C scraped by the scraping cutter 12 may be caught between the scraping claw 12a and the tip 14a of the receiving plate 14. However, at this time, the receiving plate 14 retreats against the spring 16 to the state shown by the imaginary line in FIG. 3, and its tip 14a separates from the scraping claw 12a to release the trapped coal C. When the coal C is released and disappears, the receiving plate 14 is immediately returned to its original solid line position by the spring 16.

Although the receiving plate of this embodiment is rotatably attached by a rotary plate, the present invention is not limited to this. For example, the tip portion 14a may be structured in a sliding manner. In short, the tip portion When coal is caught in the plate and a predetermined load is applied to the tip of the receiving plate due to the scraping action of the scraping claw, at least the tip elastically retreats to release the coal C and immediately return to its original position. Any configuration that allows recovery may be used.

Since the present invention is constructed as described above, there is no risk of bending or damaging the tips of the scraping claws or receiving plate due to the pinching of loose materials, and the effect is that bulk materials can be collected safely and reliably. .
