Description

  The present invention relates to a stirring device that stirs an object to be stirred in a container mainly in the vertical direction.

  In a fermenter where raw garbage is mixed with large sawdust and decomposed by the action of a fermentation enzyme, stirring is performed so that the upper and lower layers of the sediment in the fermenter are exchanged in order to promote fermentation, and air is uniformly deposited. It is necessary to supply things.

  In an enzyme bath using large sawdust or pellets thereof, rice husk, rice bran, etc., or a mixture thereof as a bathing agent for a bath, heat generated by fermentation by a fermenting enzyme in contact with air becomes uniform in the bath. It is preferable to stir the bathing agent so that the upper layer and the lower layer are interchanged, and to supply air uniformly to the bathing agent.

  Conventionally, stirring and mixing of deposits and bathing agents in these fermenters and baths are often performed manually using a shovel, a scoop or the like, and thus require labor and skill. Conventionally, there have been fermenters and bathtubs that incorporate a screw with wing blades rotating on the peripheral surface of the rotating shaft, but the rotating wing blades are exposed to the outside, giving sufficient consideration to safety. It wasn't done.

  In view of such a situation, the inventor of the present application has developed an agitation transfer device that sequentially removes the diffused material in the fermenter or bathtub (container) from the upper layer toward the lower layer and agitates and transfers it to another container. (Patent Document 1).

  A stirring transfer device according to a conventional technique includes a screw including a spiral blade that forms a spiral path along the outer peripheral surface of a shaft body, and an upper first opening and a lower second opening. A cylindrical casing that accommodates the screw rotatably therein, a drive motor that is disposed above the shaft body and that rotates the screw, a rotation shaft of the drive motor, and an end portion above the shaft body And a shaft coupling that transmits the rotational driving force of the drive motor to the shaft body. With the first opening held upward, the second opening is introduced into the deposit, the second opening is sequentially moved from the upper layer to the lower layer of the deposit, and the screw , The deposit taken in from the second opening is transferred upward while being stirred inside the casing, and is discharged from the first opening.

Utility model registration No. 3170741

  According to the prior art, compared to human work, it can be used safely by a general person without requiring labor and skill, and the object to be stirred in the first container is sequentially taken from the upper layer to the lower layer. Can be stirred and transferred to the second container.

  In the prior art, transfer from the first container to the second container is premised, but if the stirring transfer device is applied to one container, the material to be stirred in the container can be stirred in the vertical direction.

  On the other hand, when stirring also in the horizontal direction, the stirring device (stirring transfer device) is once removed from the container and then inserted in another position. In order to uniformly stir in the horizontal direction, the operator needs to repeat the insertion and removal operations while changing the stirring position.

  By the way, the stirrer according to the prior art is characterized by being small and light. However, the weight of the stirring device cannot be ignored in consideration of repeated insertion and removal operations. The labor burden on the operator still remains. Therefore, further improvement is expected.

  This invention solves the said subject, and it aims at providing the stirring apparatus which can reduce an operator's labor burden especially by achieving weight reduction.

  The inventor of the present application manufactured a conventional stirring device and various improved models, and repeated the demonstration experiment assuming the stirring of the enzyme bath. As a result, the following findings were obtained.

  Since the conventional stirring apparatus assumes transfer of the material to be stirred from the first container to the second container, a cylindrical casing is essential. On the other hand, when the stirring in the container is assumed, there is no problem even if a part of the material to be stirred in the lower layer of the container escapes to the side when the material to be stirred is transferred to the upper layer. That is, a part of the material to be stirred that has escaped to the side temporarily returns to the empty space below and is transported upward again. Further, after stirring at the position, stirring is performed again at the adjacent stirring position. . As a result, it is stirred uniformly.

  Focusing on the above, it was concluded that a cylindrical casing is not always necessary. On the other hand, it was confirmed that the weight of the cylindrical casing cannot be ignored.

  Furthermore, attention was paid to the fact that the cylindrical casing is an obstacle to the device insertion / extraction. That is, an insertion resistance force is generated when the cylindrical casing is inserted into the material to be stirred in the container. A frictional force is generated when the cylindrical casing is removed from the material to be stirred in the container. This increases the labor burden on the operator. That is, the cylindrical casing is not only an increase in weight but also a factor of increasing the labor load than expected.

  The inventor of the present application has come up with the present invention based on the above knowledge.

<First Embodiment>
~Constitution~
FIG. 1 is a perspective view of a stirring device according to the first embodiment (embodiment 1-1). The stirring device includes a shaft 2 (first shaft), a stirring blade 4, a drive motor 6, and an operation handle 8.

  The drive motor 6 is disposed in the motor cover, and the shaft 2 is connected to the drive shaft of the motor. The shaft 2 is rotated by a drive motor 6. On the outer periphery of the shaft 2, stirring blades 4 are arranged in the form of screws.

  The stirring blades 4 are preferably continuous as shown in the figure, but a plurality of stirring blades 4 may be provided intermittently. The rotation radius of the screw, the lead (axial distance corresponding to one rotation), and the number of rotations are appropriately set according to the application.

  An operation handle 8 is provided on the upper portion of the motor cover.

~ Operation ~
As an example of the operation, stirring of the enzyme bath will be described. The bath (container) of the enzyme bath contains large sawdust or pellets thereof, rice husk, rice bran, etc., or a mixture thereof. These are objects to be stirred (objects to be stirred).

  First, the stirring device is supported from above via the operation handle 8. While the drive motor 6 is rotated forward, the lower end of the shaft 2 is inserted into the stirring material upper layer in the container. The shaft tip moves downward by the weight of the stirring device and the reaction force of stirring.

  The stirring device is held in an appropriate position via the operation handle 8. The forward rotation of the drive motor 6 is continued and the material to be stirred is stirred. The stirring blade 4 arranged in a screw form forms a spiral path (transfer path) by rotation. The material to be stirred in the lower layer is transferred upward via a spiral path.

  At this time, it is assumed that the rotational speed of the drive motor 6 is about 300 to 700 RPM.

  When the material to be stirred in the lower layer of the container is transferred to the upper layer, a part of the material escapes to the side. The material to be stirred that has escaped to the side temporarily returns to the empty space below and is transferred upward again. When the material to be stirred in the lower layer is transferred upward, the material to be stirred in the upper layer moves to the side. That is, a steady flow from the lower side to the upper side around the axis is formed. As a result, it is stirred uniformly in the vertical direction.

  Thereafter, in order to stir also in the horizontal direction of the container, the stirring device is once removed from the container and then inserted in another position. The stirring device is pulled up via the operation handle 8. When the driving motor 6 is rotated in the reverse direction and the reaction force is used, the shaft 2 can be easily removed. Change the stirring position, repeat the insertion / removal operation, and stir the container in the horizontal direction.

~effect~
The stirring device of the first embodiment has a sufficient vertical stirring effect even without a cylindrical casing. Since there is no cylindrical casing, the weight can be reduced compared to the conventional type. In the first embodiment, since the holding of the stirring device is involved, the weight reduction of the device directly contributes to reducing the labor burden on the operator.

  Furthermore, since there is no cylindrical casing, the insertion resistance force when inserting the device and the friction force when removing the device are reduced. In this respect as well, the labor burden on the operator can be reduced.

-Modification (Embodiment 1-2)-
FIG. 2 is a perspective view of a stirring device according to a modification (Embodiment 1-2).

  In the above embodiment (Embodiment 1-1), it is necessary to bring the bottom end of the stirring blade 4 close to the bottom surface of the container so as to reliably stir the material to be stirred near the bottom surface of the container. However, when the lowermost end of the stirring blade 4 comes into contact with the bottom surface of the container, a large reaction occurs, and vibration caused by this may be transmitted to the operator via the shaft 2 and the operation handle 8. Since the vibration is suppressed by the human power of the operator, the labor burden increases.

  With respect to this problem, in Embodiment 1-2, the reduced diameter stirring blade 10 is provided so as to be continuous with the lowermost end of the stirring blade 4.

  In the illustrated example, the reduced diameter stirring blade 10 has the same lead as the stirring blade 4. The number of rotations is half rotation (0.5 rotation). The rotation radius at the upper end is the same as that of the stirring blade 4, and the diameter decreases as it goes downward, and the rotation radius at the lower end is half that of the stirring blade 4.

  In Embodiment 1-2, when the bottom end of the reduced diameter stirring blade 10 is in contact with the bottom surface of the container, the contact area is reduced as compared with Embodiment 1-1, so that the reaction that occurs is also reduced. As a result, vibration is also reduced and the burden on the operator can be reduced.

Second Embodiment
~Overview~
FIG. 3 is a perspective view of the stirring device according to the second embodiment.

  In the conventional type and the first embodiment, the operator needs to hold the stirring device in an appropriate position during stirring. Even if the stirrer is reduced in weight, the burden on the operator still remains.

  With respect to this problem, the ground plate 12 is provided at the lower end of the shaft 2 in the second embodiment.

  The radius of the ground plate 12 is preferably 0.6 times or more the radius of the stirring blade 4. Thereby, the dead weight of a stirring apparatus can be reliably transmitted to a container bottom face. If it is less than 0.6 times, the self-weight transmission effect may be insufficient.

  The radius of the ground plate 12 is preferably 1.5 times or less of the radius of the stirring blade 4. Thereby, a stirring apparatus can be inserted and extracted easily. Further, the frictional resistance can be reduced also when the ground plate 12 rotates. If it exceeds 1.5 times, there is a risk that it may become an obstacle at the time of inserting and removing the stirring device. Further, when the ground plate 12 rotates, the frictional resistance may increase.

  The ground plate 12 may have a disk shape, but preferably has a hole or a defect.

  While rotating the stirring blade 4 by the drive motor 6, the grounding plate 12 is inserted into the material to be stirred in the container and grounded to the bottom of the container. Stirring is continued in this state.

  The weight of the stirring device is supported on the bottom surface of the container via the ground plate 12. Thereby, an operator's labor burden can be reduced.

  In the second embodiment, there are the following variations according to the difference in the connecting means between the shaft 2 and the ground plate 12.

-Embodiment 2-1
When the shaft 2 and the ground plate 12 are connected as an integral rigid body, the ground plate 12 also rotates as the shaft 2 rotates. Thereby, a container bottom part can be stirred reliably. Furthermore, the stirring device can be easily inserted and removed.

-Embodiment 2-2
The shaft 2 and the ground plate 12 are connected to each other so as to be rotatable. For example, it connects via a rotary joint. The rotation of the shaft 2 is not transmitted to the ground plate 12. Since the ground plate 12 does not rotate, no frictional resistance is generated, there is no vibration caused by this, and the labor burden on the operator can be reduced.

-Embodiment 2-3
The shaft 2 and the ground plate 12 are connected via a universal joint. The rotation of the shaft 2 is transmitted to the ground plate 12 with a variable shaft angle within a predetermined range. Embodiment 2-3 is substantially a modification of the third embodiment. That is, the shaft 2 (first shaft) and the rotating shaft (second shaft) of the ground plate 12 are formed. On the other hand, there is no stirring blade 16. Refer to the description of the third embodiment for operations and effects.

<Third Embodiment>
~background~
The inventor of the present application prototyped the stirring device of the first embodiment and the second embodiment, and stirred the enzyme bath in which an enzyme bath material was spread by about 0.6 m in a container of width 1 m × length 2 m × height 0.8 m. As a result, the demonstration experiment was repeated. While confirming the effect mentioned above, the further improvement point was also confirmed.

  The stirrer according to Embodiment 1-2 has the effects of improving the stirrability of the container bottom and reducing the vibration. On the other hand, the labor burden of the operator still remains to maintain the manpower of the stirring device. In addition, since the stress increases due to the reduction of the contact area, the bottom surface of the container may be damaged. Note that high-grade wood such as firewood is often used for enzyme bath tubs, so care must be taken when damaging containers.

  The stirrer according to Embodiment 2-1 has the effects of reducing the weight of the apparatus and further improving the stirrability of the container bottom. On the other hand, because of the occurrence of vibration, the labor burden on the operator may be increased due to warping. Furthermore, even if the operation handle 8 is slightly displaced, the angle of the shaft 2 is shaken and the grounding of the grounding plate 12 becomes unstable. As a result, the reaction caused by the rotation of the ground plate 12 increases.

  The stirring device according to Embodiment 2-2 has an effect of reducing the weight of the device and reducing the vibration. On the other hand, there is a possibility that stirring of the container bottom is insufficient.

~Constitution~
FIG. 4 is a perspective view of a stirring device according to the third embodiment. FIG. 5 is an elevational view of the stirring device according to the third embodiment. The stirring device includes a shaft 2 (first shaft), a stirring blade 4, a drive motor 6, an operation handle 8, a grounding plate 12, a shaft 14 (second shaft), and a stirring blade 16 (second stirring). Wing) and a universal joint 18.

  The universal joint (universal joint) 18 transmits the rotation of the first shaft (shaft 2) to the second shaft (shaft 14) with a variable shaft angle within a predetermined range. The universal joint 18 also transmits the axial force of the shaft 2 to the shaft 14. A screw-like stirring blade 16 is disposed on the outer periphery of the shaft 14.

~ Operation 1 and effects ~
FIG. 6 is an explanatory diagram of basic operations according to the third embodiment. The basic operation related to insertion → upper stirring → removal and the operation of stirring by forming a steady flow from below to above are the same as in the first embodiment. The operation of grounding the ground plate 12 to the bottom of the container is the same as in the second embodiment.

  The shaft 14 is rotated by the drive motor 6 via the shaft 2 and the universal joint 18. As the shaft 14 rotates, the stirring blade 16 and the ground plate 12 also rotate. Thereby, a container bottom part can be stirred reliably.

  At this time, the grounding plate 12 is moderately pressed from above by the reaction force that the stirring blade 16 moves the material to be stirred upward, and the grounding plate 12 continues to be stably grounded.

  Further, even if the operation handle 8 is moved and the angle of the shaft 2 is changed, the angular displacement is absorbed by the universal joint 18 and the ground plate 12 continues to be stably grounded.

  Since the stable grounding continues, there is no fear of reaction due to the rotation of the grounding plate 12.

  On the other hand, the contact with the bottom surface of the container is caused by the rotation of the ground plate 12. However, since the universal joint 18 is not a complete fixed end, reaction force due to contact is reduced. Furthermore, even if vibration due to frictional resistance occurs, the vibration is absorbed by the universal joint 18 and is not transmitted to the shaft 2 and the operation handle 8.

In summary, the following effects can be obtained.
The ground plate 12 can reduce the weight of the apparatus itself.
By the reaction force by the stirring blade 16 and the angle adjustment by the universal joint 18, the ground plate 12 can continue stable grounding.
Vibration can be reduced by the universal joint 18.
Thus, the labor burden on the operator can be remarkably reduced.

  Furthermore, the bottom of the container can be reliably stirred by the rotation of the stirring blade 16 and the ground plate 12. In addition, since the ground plate 12 disperses the stress, there is no possibility that the bottom surface of the container is damaged.

~ Operation 2 and effects ~
FIG. 7 is an explanatory view of the operation related to the horizontal stirring in the third embodiment.

  After the stirring in the vertical direction is continued for a predetermined time, the shaft 2 is tilted by an appropriate angle via the operation handle 8 (about 30 degrees in the clockwise direction in FIG. 7). As described above, the ground plate 12 is stably grounded by the reaction force by the stirring blade 16 and the angle adjustment by the universal joint 18.

  In this state, the operation handle 8 is pressed in the direction of the axis 2. The pressing force is transmitted to the ground plate 12 through the universal joint 18 and the shaft 14. As described above, since the contact reaction force (friction resistance) between the ground plate 12 and the bottom surface of the container is reduced, the ground plate 12 moves while continuing the ground contact (proceeding in the left direction in the illustration of FIG. 7). A part of the reaction force of the stirring blades 4 and 16 with respect to the upward movement of the material to be stirred acts as a horizontal driving force.

  In the adjacent stirring position, the vertical stirring is performed again. In this way, vertical stirring and horizontal movement are repeated to perform horizontal stirring.

  By the way, in the conventional type, the first embodiment, and the second embodiment, the operator repeats the operation of inserting and removing the apparatus and the change of the stirring position many times, and these operations are burdened by the operator.

  On the other hand, in the third embodiment, the apparatus insertion / extraction operation is performed only once, and the horizontal agitation can be performed with only a slight pressing operation. As a result, the labor burden on the operator can be greatly reduced.

<Fourth embodiment>
FIG. 8 is a configuration diagram of the main part according to the fourth embodiment. The fourth embodiment is a modification of the third embodiment, and adds an angle restraining mechanism 20.

  In the fourth embodiment, the universal joint 18 has an angle restraining mechanism 20. The angle constraining mechanism 20 includes two constraining rings 20a and 20b that face the joint center. When the angle formed between the shaft 2 and the shaft 14 is displaced, the tip of the restraining ring 20a and the tip of the restraining ring 20b interfere with each other. This restrains the angular displacement beyond the predetermined range.

  The following knowledge was obtained as a result of the verification experiment of the inventor of the present application. If the displacement is more than 45 degrees, a sufficient vertical stirring effect cannot be obtained. On the other hand, if it is less than 5 degrees, horizontal movement (operation 2 of the third embodiment) is difficult. The restraint angle is preferably about 15 to 30 degrees.

  The restraining rings 20a and 20b are rigidly connected to a commercially available universal joint. Commercially available parts can be used.

<Fifth Embodiment>
FIG. 9 is a main part configuration diagram according to the fifth embodiment. The fifth embodiment is a modification of the third embodiment and limits the configuration of the stirring blade 16.

  If the shaft 14 is too long, the moment generated on the shaft 14 cannot be ignored, and the effects of the third embodiment may not be obtained. Therefore, the shaft 14 is preferably as short as possible.

  On the other hand, stirring blades 16 are arranged on the outer periphery of the shaft 14 to assist stirring at the bottom of the container and stabilize the grounding of the grounding plate 12. In order for the stirring blade 16 to function reliably, the number of rotations is preferably 0.5 to 1 rotation. Therefore, the length of the shaft 14 is preferably as short as possible within the range in which the stirring blades 16 are provided.

  Via the universal joint 18, the lower end of the stirring blade 4 and the upper end of the stirring blade 16 are divided. On the other hand, since the upper end of the stirring blade 16 is extended to the position corresponding to the universal joint 18, the continuity of the material to be stirred can be ensured.

  The to-be-stirred material transferred to the upper end of the stirring blade 16 jumps to the lower end of the stirring blade 4 after jumping over the parting position at the position corresponding to the universal joint 18. This ensures agitation in the vertical direction.

<Sixth Embodiment>
FIG. 10 is a perspective view of a stirring device according to the sixth embodiment. The sixth embodiment is a modification of the third embodiment, and adds a transfer assisting means 22.

  The transfer assisting means 22 is composed of three frames arranged parallel to the shaft so as to enclose the stirring blades 4 and 16. The three frames are joined to two upper and lower rings to form a cylindrical framework. The upper ring is connected to the cover of the drive motor 6, and the transfer assisting means 22 is supported.

  As the drive motor 6 rotates, the stirring blades 4 and 16 form a spiral path. The material to be stirred is transferred via a spiral path. When transporting, some of the materials to be stirred escape to the side. The transfer auxiliary means 22 suppresses the amount of escape to the side and assists the transfer. That is, a part of the material to be stirred that tries to escape to the side collides with the frame, moves upward along the frame, and returns to the transfer path. Thereby, the vertical stirring effect is improved.

  Incidentally, it can be said that the transfer assisting means 22 is a modification of the conventional cylindrical casing. Therefore, there was concern that the same problems as in the prior art would occur.

  As a result of the proof experiment of the inventor of the present application, if the opening ratio of the transfer assisting means 22 is 60% or more (vs. the cylindrical casing ratio) or more, the influence of the increase in the weight of the apparatus and the labor load of the insertion / extraction work is small. On the other hand, an ascending steady flow is more reliably formed and the agitation is improved. In other words, it was confirmed that the disadvantages of the problem generation were small, the effects of the present application were maintained, further merits were added, and the effects were more than the trade-off.

  FIG. 11 is a perspective view of a stirring device according to a modification of the sixth embodiment. The transfer auxiliary means 24 is constituted by a 1/3 case (one third case) instead of the three frames. That is, the aperture ratio is 66% (ratio of cylindrical casing).

  By the way, the universal joint 18 can adjust the angle between the shaft 2 and the shaft 14. The shaft 2 is slightly inclined toward the one third case side through the operation handle 8.

  A part of the material to be stirred that tries to escape from the side to the one third case side is restrained by the one third case and moves upward along the one third case. On the other hand, part of the material to be stirred that tries to escape from the side opposite to the one-third case side is subjected to the weight of the material to be stirred and returns to the transfer path. Thereby, the vertical stirring effect is improved.

<Seventh embodiment>
FIG. 12 is a perspective view of an additional kit according to the seventh embodiment.

  The additional kit 26 is connected to the shaft 2 (first shaft) that is rotationally driven by the drive motor 6. The additional kit 26 includes a connection portion 28, a shaft 14 (second shaft), the universal joint 18, and the ground plate 12.

  The connecting portion 28 is provided at one end of the universal joint 18 and connects the shaft 2 (first shaft).

  An existing and commercially available stirring device includes a first shaft, a drive motor that rotationally drives the first shaft, and a stirring blade provided on the first shaft. Therefore, the additional kit 26 can be attached with a little processing of a commercially available stirring device.

  Thereby, it becomes a stirring apparatus equivalent to Embodiment 2-3.

For example, the first embodiment (basic form) and the sixth embodiment (transfer assist) may be combined, or the fourth embodiment (angle constraint) and the fifth embodiment (details of the lower stirring blade) may be combined. good.

  Furthermore, the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope of the present invention.

  For example, the universal joint 18 is shown as a specific example of the rotation transmission / vibration reduction means interposed between the first axis (axis 2) and the second axis (axis 14). The rotation of the shaft 2 is transmitted to the shaft 14, the axial force of the shaft 2 is transmitted to the shaft 14, and the vibration transmitted from the shaft 14 side to the shaft 2 side is reduced (even if it can be completely cut off). ) What is necessary is just to have a function. For example, it can be replaced by hard rubber.
