[Technical field]

[0001] The present invention relates to a kneading device. [Background technology]

[0002] Conventionally, there has been a technique for kneading raw materials such as resin-based paving materials using a mixer equipped with a rigid mixing blade or agitating rod (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-117581 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional kneading devices, cleaning the kneaded material that adheres to the kneading section after kneading the raw materials is cumbersome. Also, the raw materials near the inner surface of the container are not mixed sufficiently. The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a kneading device that can improve the cleanability of the kneading section and facilitates mixing of raw materials. [Means for solving the problem]

[0005] The present invention relates to a kneading device that kneads raw materials to produce a kneaded product, and is characterized in that it comprises a container for storing the raw materials and a kneader, and the kneader has a kneading section formed in a lattice shape using a flexible material. Effect of the Invention

[0006] According to the present invention, the cleaning property of the kneading section can be improved, and the raw materials can be easily mixed. [Brief description of the drawings]

[0007] [Figure 1]FIG. 1 is a diagram showing an entire kneading device. [Diagram 2] FIG. [Diagram 3] FIG. 2 is a schematic diagram showing a container and a kneading section when the kneading device is in operation. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] (Embodiment) [1-1. Configuration] [1-1-1. Configuration of the kneading device] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a diagram showing an entire kneading device 1 according to the present embodiment, in which UP indicates the upward direction. The kneading device 1 includes a main body frame 2, a kneader 3 supported by the main body frame 2, and a container 4 in which raw material P is stored.

[0009] The main body frame 2 has a loading platform 5 at its lower part. The loading platform 5 is formed in a rectangular shape in a plan view. The main body frame 2 has a pair of first pillars 6 extending obliquely upward from each side extending in the longitudinal direction of the loading platform 5, and a pair of second pillars 7 extending vertically from one side extending in the lateral direction of the loading platform 5.

[0010] The pair of first pillars 6 are connected at their upper parts to the second pillars 7 by connecting parts 10. One of the first pillars 6 is provided with a reel support plate 11 in the center in the up-down direction. A rope reel 12 equipped with a handle 13 is provided on the reel support plate 11. A support rope R is hung on the rope reel 12. The support rope R supports the kneader 3 via a first pulley 14 and a second pulley 15 (described later) that are further provided on the one of the first pillars 6.

[0011] A bridge portion 16 is provided at the upper ends of the pair of second pillar portions 7, connecting the respective second pillar portions 7. A hook portion 17 formed in an arc shape is provided below the center of the bridge portion 16. A second pulley 15 is connected to the hook portion 17. A support rope R extending from the first pulley 14 is hung on the second pulley 15. The pair of second pillars 7, the bridge portion 16, the second pulley 15, and the support rope R hanging down from the second pulley 15 constitute a gate-shaped member that supports the kneader 3. The kneader 3 is disposed between the pair of second pillars 7.

[0012] The kneader 3 is operated by a drive source (not shown) and is configured as a device that rotates a kneading shaft portion 41. The kneader 3 includes a kneader body 30. A gripping portion 31 formed in a hollow shape is provided on the upper portion of the kneader body 30.

[0013] The end of the support rope R hanging vertically downward from the second pulley 15 is passed through the gripping part 31 of the kneader 3 and secured by a rope clip 18. The kneader 3 is installed so that it can move up and down by turning the handle 13. The support rope R is a flexible rope made of multiple twisted metal wires.

[0014] In addition, the pair of second pillars 7 include a second bridging portion 19 that connects the pair of second pillars 7 to each other and is provided so as to be inserted into the grip portion 31. Even if the handle 13 is excessively operated in a direction that moves the kneader 3 downward, the grip portion 31 abuts against the second bridging portion 19, and the kneader 3 does not move further downward.

[0015] A container 4 containing raw material P is placed on the loading platform 5. The raw material P is, for example, a resin-based paving material. The raw material P is, for example, a resin mortar used for paving, and is composed of a base material made of epoxy resin, a hardener for hardening the base material, aggregate, and water. The raw material P may also be composed of cement, aggregate, and water. The container 4 is not fixed to the loading platform 5, and after the mixed material is prepared, it can be replaced with another container 4. The kneading device 1 is particularly suitable for small-scale paving construction.

[0016] As shown in FIG. 1, a cover 4A is provided in the container 4 to prevent the raw material P contained in the container 4 from scattering. The platform 5 has four wheels 8 on the bottom surface thereof via casters 9, which allows the kneading device 1 to be moved. In addition, the platform 5 allows the drive source (not shown) of the kneader 3 to be placed thereon.

[0017] [1-1-2. Composition of the kneading section] FIG. 2 is a perspective view of the kneading section 40. As shown in FIG. 1 and 2, the kneader 3 includes a kneading shaft portion 41 extending vertically downward from the kneader main body 30, and a rod-shaped member 43 formed at the lower end of the kneading shaft portion 41 and extending in a direction perpendicular to the kneading shaft portion 41. The kneading shaft portion 41 and the rod-shaped member 43 extending from the lower end are formed in a substantially T-shape. When the kneader 3 operates, the kneading portion 40 and the rod-shaped member 43 rotate integrally with the kneading shaft portion 41.

[0018] The kneader 3 includes a pair of cylindrical members 45 through which the rod members 43 are inserted. Since the pair of cylindrical members 45 are configured symmetrically, one of the cylindrical members 45 will be described and the description of the other cylindrical member 45 may be omitted.

[0019] The tubular member 45 is formed in a hollow cylindrical shape. A female screw portion 47 that screws into the fixing member 49 is formed on the side of the tubular member 45. The fixing member 49 is composed of a screw with a hexagonal head. When the fixing member 49 is tightened, the tip of the fixing member 49 abuts against the rod-shaped member 43, and the tubular member 45 can be fixed to the rod-shaped member 43. When the fixing member 49 is loosened, the tubular member 45 becomes slidable in the direction W shown in FIG. 2.

[0020] The kneading section 40, which is formed in a lattice pattern, is connected to the cylindrical member 45. The kneading section 40 is composed of wires arranged in a lattice pattern. The wires in the kneading section 40 are flexible ropes made by twisting together multiple wires of metal bundles, similar to the material forming the support rope R. Note that the wires in the kneading section 40 may be flexible and may have a different diameter from the support rope R. The number, diameter, and twisting method of the metal bundles constituting the wires in the kneading section 40 can be changed as appropriate.

[0021] Three wire insertion parts 51A, 51B, 51C are welded to the lower surface of the cylindrical member 45 in a state in which the rod-shaped member 43 is inserted through the cylindrical member 45. A first vertical wire 53, a second vertical wire 55, and a third vertical wire 57 are inserted into holes (not shown) of the wire insertion parts 51A, 51B, 51C in the order of approach to the kneading shaft part 41, and the first vertical wire 53, the second vertical wire 55, and the third vertical wire 57 are welded to the wire insertion parts 51A, 51B, 51C, respectively.

[0022] The first vertical wire 53, the second vertical wire 55, and the third vertical wire 57 are provided to hang down vertically and are formed to a predetermined dimension. The first vertical wire 53, the second vertical wire 55, and the third vertical wire 57 are examples of "vertical wires".

[0023] The kneading section 40 includes a first horizontal wire 59, a second horizontal wire 61, and a third horizontal wire 63, which are welded perpendicularly to the first vertical wire 53, the second vertical wire 55, and the third vertical wire 57. The first horizontal wire 59 is disposed at the lower tip portions 53A, 55A, and 57A of the vertical wires, the second horizontal wire 61 is disposed above the first horizontal wire 59, and the third horizontal wire 63 is disposed above the second horizontal wire 61. The vertical distance between the lower surface of the tubular member 45 and the third horizontal wire 63 is wider than the vertical distance between the first horizontal wire 59 and the second horizontal wire 61.

[0024] The first horizontal wire 59, the second horizontal wire 61, and the third horizontal wire 63 are examples of “horizontal wires.” In addition, in the description of this embodiment, the vertical wires and horizontal wires may be collectively referred to simply as “wires.”

[0025] The first horizontal wire 59, the second horizontal wire 61, and the third horizontal wire 63 are formed to a predetermined dimension. One end of each of the first horizontal wire 59, the second horizontal wire 61, and the third horizontal wire 63 is welded to the side surface of the first vertical wire 53 on the kneading shaft portion 41 side, and the other end is welded to the side surface of the third vertical wire 57 on the opposite side to the kneading shaft portion 41. The first horizontal wire 59 may be welded to the tip of the tip portion 53A, 55A, 57A of the vertical wire.

[0026] The second horizontal wire 61 and the third horizontal wire 63 are welded to one side of the second vertical wire 55. In other words, the second vertical wire 55 is welded to the same side of each of the second horizontal wire 61 and the third horizontal wire 63.

[0027] The kneading section 40 includes a wire insertion section 51B to which the second vertical wire 55 is connected, a third horizontal wire 63, and a reinforcing wire 65 welded to the second horizontal wire 61 and arranged along the second vertical wire 55. When viewed in a direction perpendicular to the lattice-shaped surface constituting the kneading section 40, the second vertical wire 55 and the reinforcing wire 65 overlap each other. In addition, the reinforcing wire 65 is arranged so that the third horizontal wire 63 and the second horizontal wire 61 are located between the second vertical wire 55 and the reinforcing wire 65.

[0028] [1-2. Effects, etc.] FIG. 3 is a schematic diagram showing the container 4 and the kneading section 40 when the kneading device 1 is in operation. The container 4 is a kneading tank made of resin and has a cylindrical shape. The container 4 has a bottom surface 71, a wall portion 73 rising from the bottom surface 71 so as to widen in the outer circumferential direction, and an opening 75 formed in the upper part of the wall portion 73.

[0029] When kneading the raw material P to produce a kneaded product, as shown in FIG. 1, the container 4 is placed on the loading platform 5 so as to be located directly below the kneader 3. At this time, if the kneader 3 is lifted upward by operating the handle 13, it is easier to place the container 4. Next, the kneader 3 is lowered by operating the handle 13 so that the kneading section 40 enters the container 4. At this time, if the kneader 3 is lowered to the extent that the tip of the vertical wire comes into contact with the inner surface of the bottom surface 71 of the container 4, it is easier to knead the raw material P near the bottom surface of the container 4. The height of the kneader 3 relative to the container 4 may be adjusted either before or after the raw material P is placed in the container 4.

[0030] When the kneader 3 adjusted to the appropriate height is operated, the kneading shaft portion 41 rotates integrally with the kneading section 40 around the axis L. As shown in FIG. 3, when the kneader 3 is operating, centrifugal force acts on the kneading section 40, and the vertical wires are bent in a direction away from the kneading shaft portion 41.

[0031] The first vertical wires 53 are bent by centrifugal force and come into contact with the inner surface of the wall portion 73 of the container 4. This makes it easy to knead the raw material P near the inner surface of the wall portion 73. In addition, the tip portions 53A of the first vertical wires 53 to which the first horizontal wires 59 are welded make it easy to knead the raw material P near the corner portions 77 between the bottom surface 71 and the wall portion 73.

[0032] The kneading part 40 may bend in the opposite direction to the rotation direction due to resistance to the raw material P, and the first horizontal wire 59 may move away from the bottom surface 71 of the container 4. Since the kneading part 40 includes the reinforcing wire 65, the bending of the kneading part 40 in the opposite direction to the rotation direction can be reduced, and the raw material P near the bottom surface 71 can be easily kneaded.

[0033] Since the reinforcing wire 65 is arranged along the second vertical wire 55, it does not suppress the bending of the first vertical wire 53, and it is easy to knead the raw material P near the wall portion 73. Furthermore, since the reinforcing wire 65 extends from the wire insertion portion 51B to the second horizontal wire 61 and is not located on the first horizontal wire 59, it does not suppress the bending of the kneading section 40 below the second horizontal wire 61. As a result, even if the height of the kneader 3 is adjusted to a height where the first horizontal wire 59 contacts the bottom surface 71, the kneading section 40 can knead the inner surface of the bottom surface 71 by rubbing it against the inner surface of the bottom surface 71 by bending the kneading section 40 below the second horizontal wire 61 of the kneading section 40 when the kneading section 40 rotates.

[0034] In addition, the diameter of the opening 75 of the container 4 and the ratio of the diameter of the opening 75 to the bottom surface, etc., can be appropriately changed. Since the pair of cylindrical members 45 each include a fixing member 49 and are formed to be slidable along the rod-shaped member 43, the position of the kneading section 40 can be appropriately changed according to the shape of the container 4. This makes it easier to mix the raw material P near the inner surface of the wall portion 73 of the container 4.

[0035] As described above, the raw material P is kneaded, and a kneaded product is prepared in the container 4. The kneading section 40 in this embodiment is also easy to knead the raw material P in the portions where it is likely to remain, such as the bottom surface 71, the wall portion 73, and the corner portion 77 of the container 4. After the preparation of the kneaded product is completed, the kneading section 40 is cleaned, and the container 4 is placed on the loading platform 5 again, so that the kneaded product can be prepared again.

[0036] After the kneaded material is produced, the kneaded material adheres to the kneading section 40. When the kneaded material is dry, the kneaded material can be easily peeled off by shaking the wire of the kneading section 40 or by applying a large tension to the wire after loosening it. In other words, the kneading section 40 is made of a flexible wire, so that the kneading section 40 is easy to clean.

[0037] [1-3. Effects, etc.] As described above, the kneading device 1 of this embodiment kneads the raw material P to produce a kneaded product, and is equipped with a container 4 for storing the raw material P and a kneader 3, and the kneader 3 is equipped with a kneading section 40 formed in a lattice shape from a flexible material.

[0038] According to this configuration, the kneading section 40 is bent, which improves the cleanability of the kneading section 40 and makes it easier to mix the raw material P.

[0039] In addition, the kneading section 40 is provided with a first vertical wire 53, a second vertical wire 55, and a third vertical wire 57 that are arranged to hang down, and when the kneader 3 is operating, the first vertical wire 53 (first vertical wire) that is arranged at the outermost side in the circumferential direction of the container 4 may come into contact with the inner surface of the wall portion 73 of the container 4.

[0040] According to this configuration, when the kneader 3 is in operation, the first vertical wires 53 bend so as to contact the inner surface of the wall portion 73 of the container 4. Therefore, the raw material P near the inner surface of the wall portion 73 of the container 4, where the raw material P is likely to remain, is also easily kneaded.

[0041] In addition, the kneading section 40 includes a first horizontal wire 59, a second horizontal wire 61, and a third horizontal wire 63 connected to the first vertical wire 53, the second vertical wire 55, and the third vertical wire 57, and the first horizontal wire 59 arranged at the bottom of the kneading section 40 may be connected to the lower tip portions 53A, 55A, and 57A of the first vertical wire 53, the second vertical wire 55, and the third vertical wire 57.

[0042] According to this configuration, the first horizontal wires 59 can form a lattice near the lower tips 53A, 55A, and 57A of the vertical wires, and the raw material P can be efficiently kneaded by the kneading section 40.

[0043] In addition, the first horizontal wire 59 is connected to the lower ends of the first vertical wire 53 , the second vertical wire 55 , and the third vertical wire 57 , and is disposed at a position where it contacts the bottom surface 71 of the container 4 . According to this configuration, the kneading section 40 easily comes into contact with the inner surface of the bottom surface 71 of the container 4. The raw material P near the inner surface of the bottom surface 71 of the container 4 where the raw material P is likely to remain is easily mixed.

[0044] The kneading device 1 also includes a pair of second pillar sections 7, a bridging section 16 connecting the upper parts of the second pillar sections 7, and a second pulley 15 provided on the bridging section 16, and includes a kneader 3 supported so as to hang down from the second pulley 15 on a support rope R extending from the rope reel 12. According to this configuration, the height of the kneader 3 can be changed by rotating the rope reel 12, and the distance between the kneading section 40 and the bottom surface 71 of the container 4 can be adjusted. Therefore, the raw material P near the inner surface of the bottom surface 71 of the container 4, where the kneading section 40 is likely to come into contact with the inner surface of the bottom surface 71 of the container 4 and where the raw material P is likely to remain, can be easily mixed. In addition, when the container 4 is replaced with another container, the kneader 3 can be moved upward to improve workability.

[0045] In addition, the kneader 3 is provided with a kneading shaft portion 41 (kneading shaft), the kneading shaft portion 41 is provided with a rod-shaped member 43 extending in a direction perpendicular to the kneading shaft portion 41, the kneading portion 40 is provided with a pair of tubular members 45 through which the rod-shaped members 43 are respectively inserted, the tubular members 45 are fixed to the rod-shaped members 43 by a fixing member 49 (fixing device), and the first vertical wire 53, the second vertical wire 55, and the third vertical wire 57 may be connected to the tubular member 45.

[0046] According to this configuration, the position of the kneading section 40 can be changed in accordance with the diameter of the vessel 4. Therefore, the raw material P near the inner surface of the wall portion 73 of the vessel 4, where the raw material P is likely to remain, is also easily kneaded.

[0047] The kneading section 40 may also include a reinforcing wire 65 that hangs down along at least one of the multiple vertical wires.

[0048] According to this configuration, the reinforcing wire 65 reduces the flexibility of the kneading section 40. Therefore, it is possible to suppress a phenomenon in which the kneading section 40 is excessively bent due to the resistance of the raw material P, and the raw material P cannot be kneaded sufficiently.

[0049] In addition, the reinforcing wire 65 may be disposed inside the first vertical wires 53 and the first horizontal wires 59 .

[0050] According to this configuration, the reinforcing wire 65 can maintain the flexibility of the first vertical wires 53 and the first horizontal wires 59 constituting the portion near the bottom surface 71 and the wall portion 73 of the container 4 in the kneading section 40 while reducing the flexibility of the kneading section 40. The raw material P near the bottom surface 71 and the inner surface of the wall portion 73 of the container 4 is easily mixed.

[0051] (Other embodiments) As described above, the above embodiment has been described as an example disclosed in this application. However, the technology in this disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the above embodiment to form a new embodiment. Therefore, other embodiments will be exemplified below.

[0052] Although the number of vertical wires and horizontal wires is three, the present invention is not limited to this, and the number of wires may be changed appropriately as long as the kneading section 40 is formed in a lattice shape. Although the first vertical wire 53, the second vertical wire 55, and the third vertical wire 57 are configured to have a predetermined dimension, the dimensions of the vertical wires may be different from each other. Although the first horizontal wire 59, the second horizontal wire 61, and the third horizontal wire 63 are configured to have predetermined dimensions, the dimensions of the horizontal wires may be different from one another.

[0053] The position and number of the reinforcing wires 65 are not limited as long as they suppress excessive bending of the entire kneading section 40 and allow the portions of the kneading section 40 near the bottom surface 71 and wall portion 73 of the container 4 to bend.

[0054] The fixing member 49 may be configured to slidably fix the cylindrical member 45 to the rod-shaped member 43. For this purpose, for example, the fixing member may be configured by providing a plurality of holes in the rod-shaped member 43, providing rod-shaped pins in the cylindrical member 45, and inserting the pins into the holes.

[0055] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents. [Explanation of symbols]
