Description of the Related Art A concrete mixer is one in which cement, water, sand, gravel and the like are kneaded, but concrete often adheres to the inside of the mixer and hardens. When this concrete adheres and grows, the effect of stirring and mixing weakens, and there is the inconvenience that it becomes a large lump and mixes into the concrete that is the product. Alternatively, the hardened concrete, which had been cleaned with a brush or the like and could not be removed by any means, was peeled off with a hammer or the like. Also, recently
As presented in Japanese Patent Publication No. 7-112695, there is provided a washer capable of automatically injecting high-pressure water into the mixer and automatically changing the injection direction, which is activated at the end of work to prevent concrete from adhering and solidifying. Are known. But,
A conventional washer that sprays high-pressure water and automatically changes the spraying direction is complicated and expensive, and has to be operated after each work, which is troublesome.
The applicant of the present application, as Japanese Patent Application No. 2000-162739, effectively prevents concrete from adhering to the stirring rotary shaft of the concrete mixer with a simple device, and easily attaches, detaches, and replaces it when it is consumed. We provide a cleaning ring for a forced twin-screw concrete mixer that can

発生が著しく減少させるという作用も有する。In order to engage the cleaning ring 3 with the rotary shaft 21, an opening means for opening and joining the cleaning ring 3 in two parts is required.
As shown in the figure, this embodiment has two connecting portions 33, and the cleaning ring 3 is formed by bending a round bar into a hexagonal shape and is divided into two semicircular dividing members 32. At two positions on both ends of the divided dividing member 32, there are provided connecting portions 33 for connecting both dividing members. The specific configuration of the connecting portion 33 is as shown in FIG. 3 (b). Notch portions 331, 331 are formed by cutting the end portion of the member 32 into half, and are fixedly coupled with a countersunk bolt 332 and a female screw portion 333 by a tap.
In this case, there is no protruding portion and the rotary shaft 21 is not damaged more than necessary, and when the ring is a prism, it is easy to process and advantageous. Since the cleaning ring 3 is used semipermanently, the joining means of the dividing member 32 may be joined by welding means even if it is not removable. Since the first embodiment has the above-described structure, the cleaning ring 3 has a simple structure for use, and when the stirring rotary shaft rotates constantly, the cleaning ring also rotates with the rotation of the stirring rotary shaft. On the other hand, it is possible to more effectively and automatically prevent concrete from adhering to the stirring rotating shaft of the concrete mixer due to frictional force. Further, the rotation of the cleaning ring promotes the mixing of concrete and the like in the vicinity of the stirring rotary shaft, and reduces the generation of cement balls that tend to form in the portion within the rotating circle of the stirring blade. Rotation is temporarily blocked at the corners of the to become non-uniform rotation, and this non-uniform rotation acts to resist the flow direction of concrete, etc., further promoting the mixing of concrete, etc. If so, it also has the effect of significantly reducing the generation of cement balls generated in the portion within the rotating circle of the stirring blade.

When used, the cleaning ring has a simple structure, and when the stirring rotary shaft rotates constantly, the cleaning ring also rotates with the rotation, but frictional force is generated on the shaft surface of the rotary shaft 21 and the stirring rotary shaft of the concrete mixer. More effectively and automatically prevent concrete from adhering to. Further, the rotation of the ring is temporarily blocked by the convex protruding portion 62 on the inner circumference of the cleaning ring 6 to cause uneven rotation, but it acts so as to resist the flow direction of concrete or the like and mixes concrete or the like. In this embodiment, the generation of cement balls generated in the portion within the rotating circle of the stirring blade in the conventional mixing device is significantly reduced. Further, since the center line X in the longitudinal direction of the trapezoidal protrusion 62 is provided obliquely to the center line Y of the inner circumference of the cleaning ring 6 at a predetermined angle α, the protrusion close to the rotary shaft 21 The portion 62a is pushed by the concrete flow rotating with the rotating shaft 21 to move the cleaning ring 6 itself in the horizontal direction, and the protruding portion 62b next to the rotating shaft is skewed in the opposite direction. The cleaning ring 6 itself moves in the horizontal direction in the opposite direction to the front by being pushed by the concrete flow that rotates together with the rotating shaft, and as a result, the cleaning ring 6 itself meanders left and right in a wide range of the axial surface of the rotating shaft 21. It has the function of cleaning a wide area. In this case, by further moving the cleaning ring to the left and right, it has the effect of further promoting the mixing around the stirring rotary shaft and further reducing the generation of cement balls. It should be noted that this angle α has no effect of moving to the left or right even if it is too small or too large. The range of 20 ° to 70 ° is good, and in this embodiment, it is set at an angle of about 60 ° alternately in opposite skewed states, and the moving speed is made faster and the moving range is made wider.

As shown in FIG. 9 (a), the two split members 65 are circular when viewed from the direction of the rotation axis. The cleaning ring 3 can be assembled and disassembled at the connecting portion 66, and four projecting portions 67 are provided on the inner circumference of the cleaning ring 3. Then, as shown in FIG. 9 (b), along the circumference of the two split members 65 of the cleaning ring 6,
Its width direction is a horizontal direction, that is, a shape 68 meandering in the left-right direction of the circumferential surface. Since the sixth embodiment has the above-described configuration, the meandering shape 68 has a width Z of the meandering shape 68 that is apparently larger than the actual width of the cleaning ring 6 in use, and thus the cleaning range is wider.

On the contrary, the split member 65 of the ring may have only the meandering shape 68 by removing the protruding portion 67. Further, although the present embodiment is a circular ring when viewed from the direction of rotation, it may be a polygon or an ellipse,
The size of the inner diameter of the cleaning ring 6 was about 1.3 to 2 times the diameter of the rotating shaft 21 of the stirrer 2. Then, as described above, with the simple structure of the cleaning ring, when the stirring rotary shaft rotates constantly, the cleaning ring also rotates with the rotation, and a frictional force is generated on the shaft surface in a wide range of the rotary shaft 21 to cause the concrete to rotate. It has the effect of more effectively and automatically preventing concrete from adhering to the stirring rotary shaft of the mixer. Also,
Although the rotation of the ring is temporarily blocked by the convex protruding portion 62 on the inner circumference of the cleaning ring 6 to cause non-uniform rotation, it acts to resist the flow direction of concrete or the like and promotes mixing of concrete or the like. However, it significantly reduces the generation of cement balls generated in the portion inside the rotating circle of the stirring blade in the conventional mixing device,
Further, since the locus of the cleaning ring 6 meanders, it has the effect of further promoting the mixing around the stirring rotary shaft and further reducing the generation of cement balls.

For example, the partial operation of each embodiment is appropriately combined to perform the cleaning operation and the mixing operation. The configuration should be raised. Also,
In each embodiment, the inner wall surface of the ring is solid, but it may be satin to enhance the cleaning function. In addition, the inner diameter of each embodiment is about 1.3 to 2 times the diameter of the rotary shaft 21 of the stirrer 2. However, if it does not interfere with the stirring blade, it may be about 3 times depending on the material to be fed and the rotation speed. good. In addition to the above, the connecting means of the dividing members may be configured only by the elastic force of the ring itself like a spring washer so that the cut of the ring itself can be widened. It suffices to have a connecting portion that closes after being engaged with the shaft.
