In the following description, the material to be separated is used as a livestock litter, the first material is a compost raw material, and the second material is a livestock litter raw material.

  1 to 5 are configuration diagrams of the bucket A. FIG. The bucket A includes a stirring unit 1 disposed between the side plates A10 and A11 in the bucket main body A1 and a filter unit 2 provided on the bottom A12 of the bucket main body A1.

  The bucket main body A1 is connected to the construction machine B and digs up with the construction machine B, thereby digging up the used livestock litter C. Further, the bucket body A1 includes a tooth A13 on the front end side (excavation side) and a connection portion A14 connected to the construction machine B on the rear end side. The bottom portion A12 on the connection portion A14 side is the agitator 1 side. The circular arc is concentric with the rotation locus.

  Here, the construction machine B only needs to be able to connect the bucket body A1 and dig up the bucket body A1, and examples thereof include a hydraulic excavator, a dozer, a loader, and the like.

  The bucket main body A1 includes a stirring chamber A20 that is an independent room in which the stirring unit 1 is built in on the connecting portion A14 side, and a holding space portion that holds the dug used livestock litter C on the tooth A13 side by the wall member A2. It is divided into A21.

  The wall member A2 is concentrically continuous with the arc of the bottom part A12 and is formed to be an arc surrounding the stirring part 1. The wall member A2 and the arc of the bottom part A12 surround the stirring part 1. A built-in stirring chamber A20 is formed. As for this wall member A2, the edge part by the side of connection part A14 is made to continue with the edge part of the filter part 2. FIG.

  In the wall member A2, a communication port A23 that communicates the stirring chamber A20 and the holding space A21 is opened in a range over the entire area between the side plates A10 and A11 (see FIG. 2). The communication port A23 has a total width extending over the entire area between the side plates A10 and A11, and an overall height from the bottom A12 continuing from the stirring chamber A20 to the holding space A21 to the middle of the holding space A21 toward the opening A210. Open as a range.

  According to such a wall member A2, the used livestock litter C can be held in the holding space A21 at the same time as the used livestock litter C is dug by the bucket body A1. Moreover, by making the bucket main body A1 face the tooth A13 side upward (see FIG. 1), the used livestock litter C can be gradually passed from the holding space A21 to the communication port A23, and little by little. It can be moved to the stirring chamber A20. At this time, the used livestock litter C can be smoothly moved by swinging the bucket body A1.

  That is, the amount of used livestock litter C that moves to the stirring chamber A20 can be controlled by the wall member A2 and the communication port A23. Then, by controlling the amount of movement of the used livestock litter C, the stirring efficiency of the used livestock litter C of the stirring unit 1 is increased, and the adverse effect on the stirrer 1 due to stirring of a large amount of used livestock litter C is achieved. Can be prevented.

  The stirring unit 1 includes a rotating shaft 10 that is rotatably supported by the side plates A10 and A11, and a plurality of stirring members 11 that are integrally provided on the outer periphery of the rotating shaft 10. The rotary shaft 10 is formed with support shafts A16 and A17 that are penetrated and supported by the side plates A10 and A11 at both ends.

  The rotating shaft 10 is connected to a rotation transmitting portion B1 whose supporting shaft A16 is operated by the hydraulic pressure of the construction machine B, and rotates together with the supporting shaft A16 that rotates by the rotation of the rotation transmitting portion B1. The rotation transmitting portion B1 is attached to the outside of the side plate A10, and a hydraulic hose B2 from the construction machine B is piped.

  The stirring member 11 stirs the used livestock litter C in the stirring chamber A20 as the rotary shaft 10 rotates, and divides this used livestock litter C into compost raw material C1 and livestock litter raw material C2. The rotary shafts 10 are juxtaposed along the axis of the rotary shaft 10 and radially project along the longitudinal direction of the rotary shaft 10. A tip member 12 for fixing the used livestock litter C and dividing it into the compost raw material C1 and the livestock litter raw material C2 is fixed to the tip of the stirring member 11.

  The stirring member 11 only needs to be able to stir the used livestock litter C and divide the used livestock litter C into the compost raw material C1 and the livestock litter raw material C2, for example, square steel, H steel, Angle steel materials are effective.

  The filter unit 2 holds a plurality of passage spaces 20 through which the compost raw material C1 divided by the stirring unit 1 passes, and holds the livestock litter raw material C2 divided by the stirring unit 1 between the plurality of passage spaces 20 And a holding portion 21 that remains in the stirring chamber A20 (see FIGS. 4 and 5), and is provided in a range from the end of the wall member A2 on the connecting portion A14 side to the vicinity of the communication port A23.

  The filter part 2 should just be a form which can ensure the passage space 20 and the holding | maintenance part 21, for example, can be achieved by making it into a punching metal shape, a mesh shape, and a slit shape. As a configuration in which such a filter portion 2 is provided on the bottom portion A12 of the bucket body A1, a configuration in which the bottom portion A12 of the bucket body A1 is processed into a punching metal shape, a net shape, or a slit shape, and a slit or a through hole is formed in the bucket body A1. This can be achieved by the configuration using the provided skeleton bucket. Moreover, if the slits and through holes of the skeleton bucket are of a size that allows the livestock litter raw material C2 to pass through, the slits and through holes of the skeleton bucket are fixed so as to cover the punching metal or net. Etc. can be achieved.

  According to the bucket A having the above-described configuration, the used animal litter C held in the holding space portion A21 is moved from the holding space portion A21 to the stirring chamber A20 by operating the bucket body A1 so that the tooth A13 faces upward. It can be moved gradually little by little.

  Further, the used livestock litter C moved to the stirring chamber A20 is stirred by the rotation of the stirring member 11 accompanying the rotation of the stirring unit 1, and at the same time the livestock excrement lump that becomes the compost raw material C1 is crushed and made fine. The stirring member 11 hooks and pulls out a long rice straw or the like which becomes the livestock litter raw material C2 contained in the livestock dung lump etc., and the wood chip that becomes the livestock litter raw material C2 contained in the livestock dung lump etc. The used livestock litter C can be separated into compost raw material C1 and livestock litter raw material C2.

  Further, when the tip member 12 of the rotating stirring member 11 faces the filter part 2, the compost raw material C 1 is reliably grounded so that the tip part of the tip member 12 and the filter part 2 are ground. The compost raw material C1 can be pushed into the passage space 20 of the filter portion 2 while being ground and passed through the passage space 20 while being ground.

  The composting raw material C1 which is separated from the livestock litter raw material C2 by the stirring of the stirring unit 1 and gradually refined while being crushed or crushed as described above is passed through the passage space 20 of the filter unit 2. Thus, it can be left in the stirring chamber A20 by dropping it outside the bucket main body A1 and holding the separated livestock litter raw material C2 by the holding part 21 of the filter part 2.

  The animal litter raw material C2 remaining in the stirring chamber A20 can be moved from the communication port A23 to the holding space A21 by operating the bucket A so that the tooth A13 side faces downward (not shown). The animal litter raw material C2 moved to the holding space A21 can be discharged out of the bucket body A1 by operating the bucket A so that the opening A210 faces downward (not shown).

  Further, since the bucket A is used by being connected to a construction machine B capable of traveling, the composting raw material C1 and the livestock litter of the used livestock litter C can be quickly moved to each place and moved to a plurality of places. The operation of dividing into the raw material C2 can be performed efficiently.

  Therefore, since the bucket A of this embodiment divides the used livestock litter C into the compost raw material C1 and the livestock litter raw material C2 by the bucket A itself, the compost raw material C1 and the livestock bedding raw material contained in the used livestock litter C are used. The efficiency of the work divided into C2 can be achieved.

  The wall member A2 may be fixed to the bucket main body A1, or may be supported so as to open and close the stirring chamber A20 (not shown). The configuration of the wall member A2 that can open and close the stirring chamber A20 can be achieved by a configuration that supports the bucket body A1 in a detachable manner, or a configuration that supports the stirring chamber A20 so as to be rotatable in the opening and closing direction (not shown). ) As a configuration in which the wall member A2 is detachably supported with respect to the bucket body A1, the wall member A2 can be achieved by attaching the wall member A2 to the bucket body A1 using bolts and nuts (not shown).

  According to the opening and closing of the stirring chamber A20, the opening of the stirring chamber A20 can facilitate the maintenance of the stirring unit 1 and the stirring chamber A20 and the removal of the livestock litter raw material C2 held in the stirring chamber A20.

  As shown in FIG. 6, the stirring unit 1 is arranged along a spiral (shown by a one-dot chain line) D in which a plurality of stirring members 11 are coaxial with the rotation shaft 10, and radially along the longitudinal direction of the rotation shaft 10. It is good also as the form which protruded in.

  According to such a stirring part 1, there exists an effect similar to the stirring part 1 shown in FIGS. 1-3. Further, since the plurality of stirring members 11 are arranged along a spiral that is coaxial with the rotary shaft 10, the used livestock litter C can be moved along the axial direction of the stirring unit 1 while stirring. Therefore, as described above, since the grinding operation for moving the compost raw material C1 along the axial direction of the stirring unit 1 is added to the grinding operation in the rotation direction of the stirring member 11, the compost raw material C1 is more reliably made finer. And can pass through the passage space 20 more quickly.

  It should be noted that the present invention is not limited to the illustrated embodiments, and can be implemented with configurations within a range that does not deviate from the contents described in the respective claims.
