Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage type paddle feeder which cuts out and transfers powder particles to a conveyor belt below a hopper for storing powder particles such as coal. In addition,
The "paddle" also means a "plow", and the "paddle feeder" means a structure having a function of cutting out powder particles and transferring the powder particles onto a conveyor belt, and it does not necessarily include a "paddle".

[0002]

2. Description of the Related Art Conventionally, for example, in a silo for storing coal, rotary paddles are used to store coal separately for each type of coal and to dispense a plurality of types of coal onto the same conveyor to perform mixed coal. The feeder is equipped.
Typical prior art is disclosed in Japanese Utility Model Publication No. 37-1024. In such a single-sided prior art,
A conveyor for transportation is provided at the bottom of the hopper, and coal accumulated at a natural angle of repose on a horizontal shelf at the bottom of the hopper is cut out by scraping with a paddle and transferred to a conveyor belt. The slicing paddles, also called plows, can be combined radially to form a swivel wheel for unloading coal deposited on one side of the conveyor.

In Japanese Patent Publication No. 43-11126, it is possible to move on a track installed along a conveyer conveyor in a conveying direction or a vertical direction thereof, and a wheel having a cutting angle is used at an arbitrary place in a coal storage facility. Swirl during deposition and let in,
A single swivel type configuration capable of performing cutting work on a conveyor is disclosed. When moving in the transport direction on the orbit, the cutting wheel can be retracted in a direction away from the accumulation and moved to an arbitrary cutting position at high speed so that the coal does not interfere with the accumulation of coal.

Further, Japanese Patent Laid-Open No. 61-267615 discloses a double-cut type structure in which coal and the like can be cut out at the same time on both sides in the conveying direction by turning a cutting wheel. Further, in the configuration known as the double swivel type, it is possible to travel on a track along the conveyor and move to any place such as a coal storage facility,
A configuration is disclosed in which a cutting wheel turns into one of the one or the other of the other cutting openings and is inserted to perform cutting, and can move in the transport direction at a high speed at a central neutral position.

For example, when coal is mixed, it is necessary to cut out raw materials from a plurality of hoppers on the same conveyor, and generally one conveyor is installed through a plurality of hoppers. ing. The payout device is
It is necessary to be able to quickly run along the transport conveyor and stop at a required position to quickly dispense.
In a structure such as the Japanese Utility Model Publication No. 37-1024, in which the turning wheel for cutting out cannot move away from the accumulated coal or the like during movement, undesired extra cutting is performed and the movement is performed quickly. It is not possible. Japanese Examined Japanese Patent Publication 43-1
The single swivel type as disclosed in Japanese Patent No. 1126 allows quick movement when the dispensing is not performed, but the single swivel type has a poor cutting efficiency. In the case of the double-cutting type structure as disclosed in Japanese Patent Laid-Open No. 61-267615, the cutting can be performed efficiently from both sides of the conveyer conveyor, so that the cutting wheel can be efficiently used. It cannot be evacuated. If it is a double swivel type, it can be cut from both sides of the conveyor, and at the time of movement it is possible to move the swivel wheel to the neutral position and move at high speed, but cutting can not be done on both sides at the same time, Since it is on each side, it is inefficient as well as the one-sided type.
