Abstract

PROBLEM TO BE SOLVED: To reduce the length of a compost fermenting chamber in a scoop type compost fermenting chamber without reducing the number of days required for the fermentation and not reducing the production amount of the compost. SOLUTION: This material-conveying device is obtained by providing an open up type fermenting chamber for filling compost materials and a transferable conveying cut back device on the upper part of the fermenting chamber along with its longitudinal direction, installing a scoop type scoop conveyer at the conveying cut back device and a transporting conveyer positioned at its lower surface and in the rear direction, arranging the front end edge part of the transporting conveyer in the lower direction of the scoop conveyer and constituting its rear end part as transferable from the lower direction of the scoop conveyer toward its rear direction. Thereby, since it is possible to make the amount of the compost raw materials large in initial period of fermentation and small in its final period, the length of the fermenting chamber can be reduced by making the piling height of the compost in the fermenting chamber constant.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compost fermentation layer using a so-called open-type fermenter having an open upper surface, and more particularly to a method for transferring a compost material put into a fermenter and turning it over. Related to a material feeding device.

[0002]

2. Description of the Related Art Conventionally, an aerobic fermentation is carried out by putting a compost material having an appropriately adjusted water and carbon ratio into a long and narrow groove-shaped fermenter and sending air to the compost material. A composting device for composting is widely known.
The turning machine used there supports the scoop conveyor by tilting it on a trolley, moving forward, scooping up the compost material in front, dropping it back again, mixing air with the compost material, and only a predetermined amount It is equipped with a so-called scoop conveyor that has the function of being transported backward. It is also known that a transfer conveyor is attached to the scoop conveyor of such a turning machine to increase the transfer distance of the compost material (for example, Japanese Patent Application Laid-Open No. 55-113688).

[0003] A fermenter used in a conventional scoop-type fermenter requires a capacity to keep the fertilizer in the tank during the period from the input of compost material to the completion of maturation, and sometimes reaches a length of 100 m. There was something. However, it has been extremely difficult to secure a large site on which such a large fermenter can be installed. Therefore, the inventors first decomposed the fertilizer into the fermenter and decomposed as the fermentation progressed, and reduced the weight of the fertilizer. Focusing on the point of reduction, a device (FIG. 6) for controlling the amount of feed by the transfer-turning machine to be smaller in the latter stage than in the former stage of the fermenter (FIG. 6) was proposed.
-93985). That is, the conveyer cc is wound between the four rollers bb, and the lever dd supporting the right two rollers bb is rotated so that the conveyer material can be adjusted in the range of the feed distance d1 to d3. It was done.

[0004]

However, if the fermenter has a deeper depth, the amount of the fermenter decreases as the fermentation progresses. Therefore, in the turning machine of FIG. 6 shown in the prior application, the compost by the scoop conveyor aa is used. Material feed distances d1 to d3
Can be changed, but the amount that can be changed corresponds to a large amount commensurate with the weight loss of compost material, for example,
It was difficult to expand and contract over a distance of 1 m or more. Therefore,
The inventors tried to move the transfer conveyor provided behind the scoop conveyor horizontally rearward, but when trying to increase the movement distance in the front-rear direction, a gap was formed between the scoop conveyor and the transfer conveyor. As a result, there is a limit to increasing the moving distance. In addition, although it was considered that the transfer conveyor was rotated up and down, the rotation angle had to be increased in order to increase the movement distance.
It was necessary to set the transfer conveyor at a high position, and there was a problem that the turning machine became too tall.

[0005]

An object of the present invention is to provide an open type fermenter for storing compost material, and a transfer turning machine capable of moving the upper part of the fermenter along a longitudinal direction. A scoop-type scoop conveyor and a transfer conveyor located on the rear lower surface of the machine are provided, the front end of the transfer conveyor is arranged below the scoop conveyor, and the rear end is directed downward from below the scoop conveyor. It is solved by making it movable. In this case, it is preferable that the transfer conveyor is configured so as to be rotatable around an instantaneous center set at a position located below the transfer conveyor.

[0006]

[Function] The compost material scooped up from the fermentation tank by the scoop conveyor falls from the upper end of the scoop conveyor onto the transfer conveyor, is sent backward by the transfer conveyor, and falls back into the fermentation tank from the rear end. I do.
As a result, the compost material is transported by the distance from the lower end of the scoop conveyor to the end of the transport conveyor, and is simultaneously turned back. Therefore, if the rear end portion of the transfer conveyor is advanced or retracted rearward, the distance from the front end portion of the scoop conveyor to the rear end portion of the transfer conveyor, that is, the transfer distance expands and contracts. If the rear end portion of the transfer conveyor is rotated about the moment center set at the rear lower side as an axis, the length of the transfer conveyor in the front-rear direction in a plan view is extended from an inclined position substantially parallel to the scoop conveyor. And move backward.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. In FIG. 1, reference numeral 10 denotes a fermenter for fermenting a compost material 17. The fermenter 10 is not shown in its entirety, but is of a well-known open type, and is formed into an elongated groove by an elongated bottom wall 11, side walls 12 erected on both sides thereof, and an end wall 13 provided at an end. Is formed. 17 is the fermenter 10
It is a compost material that is deposited inside. Reference numeral 20 denotes a transfer turning machine which moves the upper surface of the side wall 12 in the longitudinal direction.

The transfer turning machine 20 is composed of a carriage 22, a scoop conveyor 30 supported on the carriage 22, and a transfer conveyor 40 provided behind the carriage 22. The scoop conveyor 30 is used to once scoop up the accumulated compost material 17, and
No. 0 transfers the compost material 17 scooped up by the scoop conveyor 30 to the rear and returns it to the fermenter 10 again. The carriage 22 is supported by wheels 23 rolling on rails, and is driven by a traveling motor 26 via a chain 27 to travel. The traveling direction of the carriage 22 is determined by switching the rotational direction of the traveling electric motor 26 between forward and reverse.

The scoop conveyor 30 includes a conveyor frame 31 rotatably supported upward from a position inclined by the carriage 22, a pair of rollers 32, 32 provided on the conveyor frame 31, and a pair of rollers 32, 32. 3
It is constituted by a conveyor belt 33 wound between the two. The scoop conveyor 30 is rotatably supported on the carriage 22 by the support shaft 21, and is configured to be rotatable between a solid line position and an imaginary line position as the electric screw rod 34 shown in FIG. Have been. That is, when the transfer / turning machine 20 moves backward, the scoop conveyor 30
It is configured to be able to retreat upward so as not to interfere with the compost material 17.

[0010] The transfer conveyor 40 is installed to extend rearward from the rear lower surface of the scoop conveyor, and has a front end portion of the scoop conveyor 30 in plan view so that there is no gap for the compost material 17 sent from the scoop conveyor 30 to fall. There is some penetration below. Reference numeral 49 denotes a hopper provided to guide the compost material moving from the scoop conveyor 30 to the transfer conveyor 40 so as not to be scattered around.

As shown in FIG. 4, the transfer conveyor 40 has two support rods 41 swingably supported on a carriage 22;
Rollers 4 are attached to both ends of the frame 42 suspended by
3 and 43, and is constituted by a conveyor belt 44 wound between the rollers 43 and 43. Therefore, one of the support rods 41 is connected to the electric screw rod 45.
When the transfer conveyor 40 is rotated from the upper right solid line position to the lower left virtual line position in the drawing, the transfer conveyor 40 forms an arc around the instantaneous center IC of the two support rods 41, 41 and the frame 42. Draw and rotate. Thereby, the length in plan view when the transfer conveyor 40 retreats to the lower surface of the scoop conveyor 30 can be shortened, and the length in plan view when extending backward from the scoop conveyor 30 can be increased. Can be. Therefore, although the transfer conveyor 40 has a small plan view at the time of leaving, the adjustment range of the feed length of the compost material can be set to be large.

The operation of the above embodiment will be described. The transfer reversing machine 20 simultaneously operates the scoop conveyor 30 and the transfer conveyor 40 in the posture shown by the solid line in FIG. 1, and turns the fermentation tank 10 toward the input side of the compost material 17 with the fermentation end side as the starting end, that is, While turning to the left in the figure, a turn is made. The compost material 17 is scooped up from the fermenter 10 by the scoop conveyor 30 and falls rearward from the rear end thereof in the same manner as in the conventional apparatus. In the present invention, the compost material 17 is transferred by the transfer conveyor 40 installed behind the scoop conveyor 30. It is received, transported rearward, and falls into the fermenter 10. As a result, the compost material 17 is transferred by a distance from the front end of the scoop conveyor 30 to the rear end of the transfer conveyor 40, and fresh air is mixed therein to provide an aerobic environment.

[0013] The transfer conveyor 40 is located at a position where it enters the lower side of the scoop conveyor 30 at the start end side,
Therefore, the feed distance is short. As the transfer turning machine 20 advances to the left in the figure, the transfer conveyor 40 is stepwise or steplessly moved as the support rod 40 supporting the transfer conveyor 40 is rotated by the electric screw rod 34. It gradually projects rearward from the lower side of the transfer conveyor 30, and as a result, the distance for transferring the compost material 17 is gradually increased, and the transfer turning machine 20 reaches several meters to reach the input port.
In front, protrude to the maximum and maximize the feed distance of compost material.

As described above, when the transfer turning machine 20 advances from one end of the fermenter 20 to the other end, the transfer distance of the compost material is shortened at the end of fermentation when the compost material 17 is reduced. The period during which the stagnation stays in the fermenter 10 is prolonged, and sufficient fermentation can be performed. Further, since the final stage of fermentation in the fermenter can be used as a place where the compost material 17 is deposited, it is not necessary to increase the overall length of the fermenter 10 even if the residence time of the compost material 17 becomes longer.

[0015]

According to the first aspect of the present invention, the transfer conveyor is attached to the scoop conveyor, so that the transfer distance of the fermented material that is made by one turn is increased regardless of the setting angle of the scoop conveyor. Can be. In addition, if the transfer distance is increased as the turning machine moves from the start end to the end, a sufficient fermentation time can be obtained even if the length of the fermenter is shortened. According to the second aspect, as the transfer conveyor projects rearward, the transfer conveyor becomes closer to a horizontal angle, and the plane projection distance increases, so that the distance that the rear end moves rearward can be increased. In addition, the angle becomes closer to the vertical as the vehicle retreats below the scoop conveyor, and the plane projection distance becomes shorter, so that the rear end can be largely moved forward. And so on.
