Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an agitation conveyance device used, for example, in a compost fermentation tank or the like to periodically stir the compost in the fermentation tank.

``Prior Art'' Conventional stirring and conveying devices of this type include rails installed above a fermentation tank formed in the shape of a vertical pool for fermenting compost, and a drive source installed on the rails. A traveling frame is provided, which is driven by the fermentation tank, and an agitator is installed below the traveling frame, and the driving source moves the traveling frame on a rail along the fermentation tank, and the agitator is driven. A device that stirs the compost in a fermentation tank is known.

``Problems to be Solved by the Invention'' However, in the conventional agitation conveyance device, the number of parts increases because the device runs on rails using a drive source mounted on a traveling frame. As the mechanism becomes more complex, the weight of the device increases, which increases the initial cost and running cost of the device.Also, since the device is driven by a drive source, the agitator is constantly energized by the compost. As a result, the load for driving the stirrer increases accordingly, which also causes problems such as an increase in running costs.

The present invention has been made in view of the above problems, and
It is an object of the present invention to provide an agitation conveyance device that does not require a driving source for running, reduces the weight of the device, and reduces initial cost and running cost.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides a rail that is laid above the pile, a traveling frame that is movable on this rail, and a conveyor that is attached to this traveling frame. Along with supporting the frame,
An endless conveyor strip is rotatably mounted around the conveyor frame, and a plurality of blade members protruding outward are fixed to the outer peripheral surface of the endless conveyor strip to drive the endless conveyor strip. , an agitation conveyance device equipped with a drive source that uses a blade member to scrape up sediment in the traveling direction and drop it to the rear side, wherein the endless conveyor strip is oriented perpendicularly to the conveyor frame. A pressure receiving plate is arranged vertically at a slight interval behind the endless conveyor strip, and this pressure receiving plate is fixed to the traveling frame.

"Function" In the present invention, by rotating the endless conveyor strip disposed perpendicularly to the conveyor frame in a predetermined direction by a drive source, the blade members of the endless conveyor strip move forward. It scoops up some sediment and transports it to the rear, where it falls.

On the other hand, a pressure receiving plate is provided at a slight interval on the rear side of the endless conveyor strip, so that the sediment scraped up by the endless conveyor strip is deposited on the rear side of the pressure receiving plate. That will happen.

That is, in the agitation conveyance device of the present invention, the amount of deposits on the front side of the endless conveyor strip is reduced;
The amount of deposits on the rear side of the endless conveyor strip and on the rear side of the pressure receiving plate increases, and as a result, the traveling frame moves forward via the pressure receiving plate due to the accumulated pressure of the deposits.

Therefore, in the stirring and conveying device of the present invention, the traveling frame can be moved forward via the pressure receiving plate by the pressure of deposits, so there is no need to provide a dedicated drive mechanism for driving the traveling frame.

On the other hand, a pressure receiving plate is provided at a slight interval on the rear side of the endless conveyor strip, so that the sediment scraped up by the endless conveyor strip is deposited on the rear side of the pressure receiving plate. As a result, the deposits do not come into direct contact with the rear side of the endless conveyor strip, thereby preventing an excessive load from being applied to the rear endless conveyor.

is attached, and this rotation shaft 7,
An endless conveyor strip 8 is rotatably mounted between the conveyor belts 7 and 7. The endless conveyor strip 8 has flat bars 8a, 8a, . . . of a predetermined length disposed in parallel and at regular intervals in a sash-like manner, and at least both ends thereof are connected in an annular manner by a band-shaped member, and is formed in an elongated elliptical shape. flat bars 8a, 8
Wing members 9, 9, . . . whose tips protrude outward are fixed at regular intervals on the outer circumferential surfaces of the blades a, . Further, the blade members 9, 9, . . . cover the front surface of the endless conveyor strip 8 by sequentially shifting and fixing their positions for each flat bar 8a. Then, an electric motor (drive source) 10 is mounted on the traveling frame 4 to rotate the endless conveyor strip 8 in the direction of scraping up the deposits T in the traveling direction upward by means of blade members 9, 9, . . . At the same time, a pressure receiving plate 11 that covers one side of the endless conveyor strip 8 is attached to the rear of the endless conveyor strip 8 at a slight distance from the endless conveyor strip 8 by a support member 12 fixed to the traveling frame 4. There is.

The traveling frame 4, as shown in FIG.
It is a rectangular frame extending radially along the central axis of the fermentation tank 1, and both ends thereof are supported by running wheels 4a, 4a, . . . mounted at opposing positions. A raw material conveyor 13 is mounted on the opposite side of the running frame 4 from where the endless conveyor strip 8 is installed, and a raw material hopper 1 is mounted near the end of this conveyor 13.
One end of a conveyor 15 for conveying raw materials from 4 is provided. In addition, a compost discharge port 16 is provided at a predetermined position on the side plate 2, and the traveling frame 4 is equipped with a driving drive source so that it can run on its own when the inside of the fermenter 1 is empty.

Next, the operation of the agitation conveyance device S according to the present invention configured as described above will be explained along with an example of its use.

According to the agitation conveyance device having the above configuration, the raw material fed from the raw material hopper 14 to the raw material inputting part 5a via the conveyors 15 and 13 passes through the vicinity of the bottom of the fermentation tank 1 sequentially along the obstacle plate 5, and then enters the fermentation tank 1. It becomes a deposit T while moving outward. Then, the sediment T that has moved to the outside is moved by an agitation conveyance device S that rotates within the fermentation tank 1 at a speed of about one rotation per day (i.e., moves as the endless conveyor strip 8 rotates). (by the blade members 9, 9, . . . ), which are scraped up from below to above, and then fall to the rear of the pressure receiving plate 11 and accumulate. Next, when the deposits T accumulated on the back surface of the pressure receiving plate 11 reach a certain amount, the pressure receiving plate 11 is pushed forward by the heavy pressure resultant force of the deposits T, thereby causing the agitation conveyance device S to move. It is propelled forward and gradually rotated and transferred inside the fermentation tank 1.
