Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for uniformly mixing a water adjusting material such as sawdust and a composting promoting material in which microorganisms are propagated in excrement of livestock. The present invention relates to a stirring device for mixing. 2. Description of the Related Art Japanese Patent Application Laid-Open No.
There are techniques described in Japanese Patent Publication No. 128966 and Japanese Utility Model Publication No. 7-3917. According to the technique described in JP-A-11-128966, a compost material is accommodated in a cylindrical mixing drum and rotated, and a granular material or the like can be relatively easily stirred and mixed. However, for a lump having a high water content such as excrement of livestock, the mixing drum has no crushing function, and it is difficult to sufficiently perform the stirring and mixing action. Also, when discharging the agitated material, the mixing drum needs to be largely inclined, which is not suitable for a large-capacity apparatus.
In addition, even in the technique described in Japanese Utility Model Publication No. 7-3917, stirring is performed by a simple screw auger, and it is possible to cope with stirring and mixing of dried or adjusted granular or powdery substances. A lump having a high rate cannot be sufficiently stirred and mixed. [0003] The present invention solves the above-mentioned drawbacks of the prior art, and can be used as a moisture control material even when the water content is high and it is agglomerated, such as livestock excrement. It is intended to rapidly and uniformly stir and mix with a composting promoting material such as microorganisms and microorganisms, and also to reduce the load at the time of stirring and mixing. [0004] Two stirring shafts 3, 2 provided with a plurality of stirring claws 2, 2 which rotate inwardly on both left and right sides inside a tank 1 and have a transfer function in the same direction A, respectively. 3, a transport shaft 5 having a plurality of transport blades 4, 4 having a stronger transport function in the opposite direction to the agitating shafts 3, 3 under the center thereof. , 3 is provided with a stirrer 2a, 2a having a transfer function in the opposite direction (counter-arrow A direction) over a certain range of the end portion in the transfer direction A, and is configured as a stirrer such as a compost. Operation and effect of the present invention Livestock excrement, a water conditioning material such as sawdust, and a composting promoting material in which microorganisms are propagated are charged into the tank 1 and the left and right sides of the tank 1 are disposed. The agitating shafts 3, 3 and the transport shaft 5 located below the center thereof are driven. Stowage, for example, compost material, located on both sides in the tank 1 is provided on the stirring shafts 3, 3 located on both left and right sides in the tank 1 and rotating inward each other.
By rotating the plurality of stirring claws 2, 2 having a feeding function toward the tank 1, the compost material is sent upward from the lower side, bypassing the side of the tank 1, further toward the center of the tank 1, and stirred. Is sequentially transported in the direction of arrow A.
Further, the compost raw material fed into the center of the tank 1 by the left and right stirring claws 2, 2 is moved in the direction of arrow B by the plurality of transfer blades 4, 4 of the transfer shaft 5 located below the center, that is, the left and right stirring shafts 3, 4. While being conveyed in the direction opposite to the conveying direction of No. 3, it is uniformly stirred and mixed by the interaction with the stirring claws 2 on both sides. Also, even if there are lumps in the compost raw granules, the crushing action due to the forced rotation of the stirring claws 2, 2 and the transport blades 4, 4 and the interaction due to the difference in the rotation direction and the transport direction are caused. The compost material can be finely separated and uniformly stirred and mixed. The end of the stirring shaft 3, 3 in the conveying direction A,
That is, when the compost raw material that reaches the rear plate 15 of the tank 1 is pressed against the rear plate 15 by the transport force, a large driving load is applied to the stirring shafts 3, 3 and each part may be damaged. Is provided with the stirring claws 2a, 2a having a transfer function in the opposite direction (the direction of the opposite arrow A) over a fixed range of the end portion of the left and right stirring shafts 3, 3 in the transfer direction A.
The feed action of the compost material conveyed in the direction of arrow A by the stirring claws 2a, 2a is alleviated, and is partially returned in the opposite direction (counter-arrow A direction). The compost material is not excessively transported and pressed against the rear plate 15 side. [0006] In the example shown in the drawings, the tank 1 is a lower tank 1
a and an upper tank 1b, and are constituted by a front plate 14, a rear plate 15, both side plates 12, 12, a bottom plate 6, and the like, which are appropriately frame-reinforced by columns or the like. Upper frame 19 of lower tank 1a
The lower frame 20 of the upper tank 1b is provided detachably by bolting or the like. To adjust the tank capacity,
An intermediate tank is interposed between the upper and lower tanks 1a and 1b by the same means. On both left and right sides of the lower tank 1a, stirring shafts 3, 3 are rotatably mounted between the front and rear plates 14, 15, respectively. Around the stirring shaft 3, a plurality of mounting brackets 21,
21 is welded over substantially the entire length.
Stirring claws 2, 2 are fitted in 1, 21 and bolted.
The stirring claw 2 is shaped like a tilling blade, that is, a thin and wide flat plate-like material is fitted and attached to the brackets 21, 21, and sequentially from the mounting portion 2 a having a predetermined height in the rotational direction a. The feeding portion 2c is formed by forming a claw portion 2b that retreats toward the front, and further bending its distal end portion toward the transport direction A side. Further, the front edges in the rotation direction are formed at an acute angle and provided with a blade portion 2d. The stirring claws 2, 2 of the left and right stirring shafts 3, 3
Are inwardly rotated in both directions. The direction of rotation is such that the right side of the front view rotates leftward and the left side rotates rightward, but the conveying direction is the same direction A, A. Are symmetrically configured. In addition, the stirring claws 2, 2 are
The compost material is conveyed in the direction of arrow A while agitating the compost material by successively changing the phase by 90 degrees from the start end side and attaching in a helical manner. In addition, two stirring claws 2, 2 are provided near the front plate 14 at the same phase position to quickly convey the compost material on the front plate 14 side to reduce the load. Further, the end of the stirring shaft 3, that is, several stirring claws near the rear plate 15, are formed with the feeding surface 2 c bent in the opposite direction to form the reverse feeding stirring claws 2 E and 2 E, so that they can be conveyed in the direction indicated by the arrow A. It is composed. Therefore,
The compost raw material sent back in the direction of arrow A by the feed surface 2c springs upward while being stirred with the compost raw material sent in the direction of arrow A by the stirring claws 2 and is sent out to the center side. Therefore, the pressure is not unnecessarily fed to the rear plate 15 side, and the load can be reduced. The transport shaft 5 is
The front and rear plates 14, 1 are located below the center of the lower tank 1a.
5, a plurality of transport blades 4 are provided around the transport shaft 5 over its entire length.
The base is welded. The transport wing 4 is made of a flat plate, and has a feeding action in the direction of arrow B by inclining its base and welding around the transport shaft 5, and a plurality of transport wings 4, 4 around the transport shaft 5. It is configured to be able to be transported in the direction of arrow B by being attached in a helical manner with the phase being sequentially changed every 90 degrees. Further, in order to increase the transfer force of the transfer blade 4, the upper surface of the scoop may be bent. In addition, since the transport shaft 5 is a single one, the compost material is taken over from the end of the two left and right stirring shafts 3, 3 for transport in the direction of arrow A, and is circulated and transported in the direction of arrow B, so that the transport amount is balanced. In order to achieve this, the blade surface of the transfer blade 4 is configured to be larger than that of the stirring claws 2 and the mounting inclination angle is set to be large. A shutter 2 is provided on the bottom plate 6 of the lower tank 1a at the end of the transport shaft 5 at a fixed distance from the front plate 14 side.
2, an openable / closable discharge port 7 is provided. The outlet 7
A plurality of reverse feed wings 4A, 4A capable of reversing the front and back with the other feed wings 4 are provided on the feed shaft 5 between the front plate 14 and the other feed wings 4. This prevents the material from being pressed against each other and increases the discharge efficiency at the time of discharge. Furthermore,
A narrow trapezoidal plate-shaped feed wing 8 is attached to the transport shaft 5 located near the center of the discharge port 7, and the compost raw material transported in the direction of arrow B by the transport wings 4, 4 is moved upward. It is configured so that it is fed up and taken over by the left and right stirring claws 2 and circulated. If the front and rear of the tank 1 are long, the rear plate 1
A similar feed blade 8 may be provided on the transport shaft 5 near the center between the discharge port 5 and the discharge port 7 to feed a part of the compost raw material upward to be taken over by the stirring claws 2 and circulate. At the end of the left and right agitating shafts 3, 3 in the transport direction A, a rake wing that rotates along the rear plate 15 and scrapes the compost material that is attached to the rear plate 15 and that is pressure-fed and rakes it toward the center. 17 is provided, and the compost raw material to be conveyed is moved to the conveying blade 4 side having the conveying function in the direction of arrow B in the center, so that the load on the stirring shafts 3, 3 can be reduced. The stirring shafts 3 and 3 on the left and right sides and the transport shaft 5 at the center are respectively equipped with the stirring claws 2 and
The working ranges are set so as to partially overlap each other in plan view, and the vertical relationship is set such that the lower end of the stirring claws 2 is located near the axis of the transport shaft 5. Also, the upper left and right edges of the transport receiving gutter 23 formed by bending the bottom plate 6 along the outer periphery of the lower portion of the transport wings 4, 4 are connected to the transport shaft 5.
And the receiving troughs 18, 18 of the left and right stirring claws 2, 2 are provided continuously from the left and right upper edges. Therefore, by forming the central upper edges of the receiving troughs 18 and 18 shallowly, the main portion of the stirring claws 2 and 2 is positioned to face the central conveying blades 4 and 4, and the range in which both are opposed to each other. By increasing the size in the vertical direction, the stirring effect due to the interaction between the two can be further improved. Reference numeral 24 denotes a motor, which is mounted on a pedestal 25 attached to the front plate 14, rotates the right stirring shaft 3 inward through a chain 26, and further drives an intermediate shaft 28 through a chain 27. By transmitting the sprockets 29, 29 between the intermediate shaft 28 and the left stirring shaft 3, the left stirring shaft 3 is also driven to be able to rotate inward. Reference numeral 30 denotes a motor, which is also mounted on the gantry 25 and rotates the transport shaft 5 via the chain 31 in the direction of arrow B. Therefore, when clogging or the like occurs when a compost raw material of a specified amount or more is put into the tank 1, the motor 30 dedicated to the transport shaft 5 is used.
And the outlet 7 is opened to discharge the compost material.
