Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kneading apparatus for kneading cement, aggregate, water, additives and the like to obtain homogeneous concrete or mortar.

[0002]

2. Description of the Related Art Concrete for forming buildings or civil engineering structures, and various concrete products such as precast concrete boards are mixed with cement, coarse aggregate, fine aggregate, and various additives when water is added and kneaded. It is made into concrete, which is then poured into a mold or the like and cured and hardened. For example, a precast concrete plate is obtained by pouring and uniformly curing the fresh concrete that has been uniformly kneaded into a formwork.

By the way, ready-mixed concrete used for forming structures and producing concrete products is generally obtained by homogenizing each material such as cement by a container rotary type kneading device or a container fixed type kneading device. It is common. That is, in order to obtain ready-mixed concrete, for example, the above materials are individually or preliminarily added as a mixture to a tilting drum mixer as a container rotating type kneading device or a ribbon type mixer as a container fixed type kneading device. Then, the mixture made of the material is subjected to the moving kneading or the diffusion kneading by the rotational movement of the drum or the spiral ribbon to homogenize the mixture.

[0004]

However, according to recent research on the kneading process, it is possible to achieve optimum homogenization of concrete only by subjecting the mixture to moving kneading or diffusion kneading by rotational movement of a drum or a spiral ribbon. It has been found that it is difficult and that even if homogenization can be achieved, the kneading takes a long time.

On the other hand, theoretical research on the optimum homogenization of the kneaded product is just the beginning, and although there are many unclear points, for example, there are research reports by Yoji Akao, Hisakazu Shindo, and Angel Hernan. "Synthesis of mixed system and its optimum layer formation" [Journal of Powder Engineering, Vol. 19 N
o. 11 (1982)], the feed layer (optimal layer) that most quickly reaches the complete mixing state is a layered mixture obtained by the folding operation of the basic model of moving mixing, that is, compression and bisection is overlaid. It is described as corresponding to a layered mixture obtained by repeating the operation of.

However, few examples of applying such a theory to a concrete kneading technique are known, and therefore, at present, a kneading device capable of carrying out such a kneading technique is not provided.

The present invention has been made in view of the above circumstances, and an object of the present invention is to put the above-mentioned kneading theory into practice in order to obtain sufficiently homogeneous concrete or mortar by a kneading operation in a short time. It is to provide a kneading device.

Concrete kneading apparatus 1 having such a structure
In order to knead the concrete material by using, the concrete material C previously put in the hopper 10 is supplied into the main body container 5 as shown in FIG. Here, the supply amount is an amount corresponding to a volume up to about half the height of the side plates 3 and 3 of the main body container 5. At this time, the hydraulic cylinder 1
4 is operated to raise the rolling roll 11 to the upper limit position as shown in FIG.

Next, the motor 27 is driven to drive the traveling platform 1.
6 is moved to move the rolling roller 11 to the position shown by the virtual line on the right side in FIG. 4, and then the rolling roller 11 is lowered to the position shown by the virtual line in FIG. Thereafter, the motor 27 is driven to rotate the rolling roller 11 and the traveling platform 16 is moved to the end plate 4a side (left side in the figure) of the main body container 5 to move the concrete (concrete in the main body container 5). Material) C is rolled into a layer.

This layered rolling state is shown in FIG.
As shown in the figure, the concrete C is rolled from the bottom plate 2 to the side plates 3 and 3 of the main body container 5 into a layered shape having a semicircular cross section which is curved so as to correspond to the inner surface shape thereof.

Next, as shown in FIG. 4, after the rolling roller 11 is raised by the hydraulic cylinder 14 to the position shown by the solid line in the figure, the cylinder devices 13 and 13 are actuated to move the left and right side plates 3 and 3. As shown in FIG. 6, it is largely tilted inward. Then, among the rolled and layered concrete C, the portion of the concrete C located on the inner surfaces of the side plates 3 and 3 is dropped in an inverted state onto the concrete C located on the bottom plate 2. overlap. In this case, since the side plates 3 and 3 are set to about 1/4 of the length of the circular arc having a semicircular section including the bottom plate 2, they are substantially folded in two as shown in FIG. Overlapping in two layers.

Next, the cylinder devices 13 and 13 are operated to return the side plates 3 and 3 to their original positions as shown in FIG. 5, and then the rolling roller 11 is lowered, after which the motor 27 is turned on. The rolling process is performed by driving and rotating the rolling roller 11, and the concrete C is rolled into a layer again. Then, the concrete C is sufficiently kneaded by repeating these rolling steps an appropriate number of times.

In the concrete kneading apparatus 1 as described above, the concrete C rolled in layers by the rolling roller 11 is piled up on the other half by the left and right side plates 3 and 3 and rolled again. Further, by repeating these operations, the operation of compressing and partially stacking on the remaining part can be repeated, so that the concrete C can be homogeneously kneaded in a short time.

In the present embodiment, the surface of the rolling roller 11 is formed into a curved surface having a smaller diameter toward both ends in the axial direction, and the bottom plate 2 and the side plates 3, 3 of the main body container 5 are formed.
Since the inner surface shape of is also formed into a curved surface corresponding to the surface shape of the rolling roller 11, the rolling action on the mixture or the admixture is uniformly performed, whereby concrete or mortar kneaded in a sufficiently homogeneous manner can be treated in a short time. You can get it at home.

Further, in the concrete kneading apparatus according to this embodiment, the rolling roller 11 is supported by the hydraulic cylinder 14 so as to be movable up and down, and the interval h between the surface of the rolling roller 11 and the bottom plate 2 of the main body container 5 is arbitrarily set. Since it can be adjusted, the rolling force for the concrete C can be freely adjusted, and therefore, the optimal rolling force can be set according to the compounding material of the concrete C and the input amount. become.

In the above embodiment, an example in which only the left and right side plates 3 and 3 can be tilted and returned is shown, but the side plates before and after the rolling roller 11 in the traveling direction, that is, the end plates 4a and 4b are also shown. Alternatively, an operating mechanism including a hinge, a cylinder device, and the like may be provided so as to be able to tilt and return inward. By doing this, the end plates 4a, 4b
The concrete C located above can also be dropped onto the concrete C on the bottom plate 2 and overlapped.

FIG. 7 shows another embodiment of the present invention. In this embodiment, one end of the mixture or admixture (concrete C) rolled by the rolling roller 11 in the running direction of the rolling roller is shown. Means B1 and B2 for transporting and stacking approximately half of the above on the remaining portion on the other end side
Are respectively provided. That is, the front and rear portions of the traveling base 16 in the traveling direction are provided with cylinder devices 35 and 36 that operate by hydraulic pressure, pneumatic pressure, electric power, or the like.
The transfer plates 35b and 36b are provided on the rods 35a and 36a of 36, and the transfer plates 35b and 36b are configured to move up and down by moving the rods 35a and 36a up and down, respectively. The plates 35b and 36b are configured to be movable along the main body container 5.

Here, although not particularly shown, it is desirable to provide a pair of left and right cylinder devices 35 and 36 in consideration of stable support of the transfer plate. Also, the transfer plate 3
The shapes of 5b and 36b are not particularly limited, but in consideration of the transferability of concrete C, the illustrated example shows a shape curved in the transfer direction toward the tip. Therefore, the transfer plates 35b and 36b are provided so as to face each other. Further, in this case, the tips of the transfer plates 35b and 36b are rounded in an arc shape so as to be uniformly slidably in contact with the surface of the bottom plate 2 corresponding to the inner surface shape of the main body container 5. .

In the case where the transfer means B1 and B2 having such a structure are provided, of the concrete C rolled by the rolling roller 11, approximately half of one end in the running direction of the rolling roller 11 is the other end. It is possible to transfer and top-load on top of the rest. That is, the rolling roller 11 is shown in FIG.
When traveling in the direction of arrow A at
When the moving locus K of the tip of the transfer plate 35b is moved as indicated by the chain double-dashed line in the figure by operating the rod 35a of No. 3, approximately half of the rolled concrete C on the end plate 4a side is moved to the end plate 4b side. It is transferred and piled up on the other half of the.

When traveling in the direction of arrow B, the rod 36b of the transfer means B2 is operated to lower the transfer plate 36b, and the movement locus K of the tip of the transfer plate 36b is intermediate between the end plates 4a and 4b in the figure. If you move it symmetrically,
Almost half of the concrete C on the end plate 4b side is transferred and piled up on the remaining half on the end plate 4a side. Therefore, by repeating the rolling process using the rolling roller 11 and the transfer process (two-layer stacking process) using the transfer means B1 and B2, it is possible to obtain concrete, mortar, or the like that has been uniformly kneaded.

In the two-layer stacking process of concrete C, both of the transfer means B1 and B2 and the method of tilting the side plates 3 and 3 may be adopted. When both are adopted, the side plates 3 and 3 are tilted as shown in FIG.
As shown in FIG. 7, a so-called alternate method may be adopted, in which the transfer means B1 is used to carry out the two-layer stacking step and then the rolling step is followed by the two-layer stacking step using the side plates. Further, a method may be employed in which after the stacking process using the side plates, the stacking process using the transfer means is performed to form four layers, and then the rolling process is performed. By doing so, the kneading in the running direction of the rolling roller 11 and the kneading in the direction perpendicular thereto (direction between the side plates 3 and 3) can be performed at the same time, so that the kneading state can be made more uniform.

In the above embodiments, the present invention is applied to a concrete kneading apparatus, but it is needless to say that the present invention can also be applied to an apparatus for kneading mortar. Further, although the example in which the cylinder devices 35 and 35 are provided as the support means of the transfer plates 35b and 36b of the transfer means B1 and B2 is shown, a link mechanism or other mechanical means may be used.
