BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kneading apparatus for various kinds of concrete, mainly a kneading apparatus suitable for solidified concrete having a small amount of water.

[0002]

2. Description of the Related Art A conventional concrete kneading method is a method in which a concrete material put into the mixing drum is stirred using gravity while rotating a tilting mixing drum.
Alternatively, a method in which a concrete material charged into a tank or a pipe is forcibly stirred by a stirring blade is exclusively adopted.

According to the above-mentioned conventional method, a relatively soft concrete material having a large amount of water can be uniformly kneaded relatively easily because of its fluidity, but a hard concrete material having a small amount of water can be used. Due to poor fluidity, it was difficult to uniformly knead with a stirring blade or the like.

[0004]

The object of the present invention is to solve the problem that it is difficult to uniformly knead a hardened concrete material having a small amount of water.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the present invention solves the above-mentioned conventional problems by forming side plates 2b, 3b rising parallel from both side edges of rectangular bottom plates 2a, 3a, and bottom plates 2a, 3a.
A pair of mixing containers 2 and 3 having end plates 2c and 3c raised at the rear end are overlapped at their mutual leading ends, and rotatably pivotally attached to a central support portion 4 below the overlapped portion. Between the mixing vessel 1 and the rear end of each of the mixing vessels 2 and 3 and the base 6 below. The mixing vessels 2 and 3 are horizontally moved about the pivot point of the central support 4. Cylinders 7 and 8 that rotate alternately from up to upright
And a pressing plate 11 which is supported by a lifting cylinder 13 so as to be able to move up and down and is provided with a vibrating body 14 at an upper portion thereof.
The present invention proposes a concrete kneading device composed of the following.

[0006]

The concrete material 9 is put into the kneading tank 1 in which the mixing containers 2 and 3 are in a horizontal state, and the mixing container 2 on one side is turned upright by the cylinder 7 to remove the concrete material 9 therein. After being incorporated in the mixing container 3 on the side, the mixing container 2 on the one side is returned to a horizontal state.

In this state, the pressing plate 11 is
The concrete material 9 loaded in the mixing container 3 on the other side is pressed from above and below while vibrating by the vibrating body 14 to compress the entire mixing tank 1.

Next, the mixing container 3 on the other side is turned upright by the cylinder 8 so that the concrete material 9 inside the mixing container 3 is rotated.
Is placed in the mixing vessel 2 on one side, and the mixing vessel 3 on the other side is returned to a horizontal state. Similarly, the pressing plate 11 is fitted into the mixing vessel 1, and vibration is applied by the vibrator 14. Concrete material 9 contained in one side mixing vessel 2
Is pressed from above and below to roll the entire mixing tank 1, and the above steps are repeated as necessary to uniformly knead the concrete material having a small amount of water.

[0009]

1 to 9 show a kneading apparatus according to the present invention and a method for kneading a concrete material using the kneading apparatus. A rectangular box-shaped kneading tank 1 is parallel to both side edges of a square bottom plate 2a. Mixing container 2 having side plates 2b, 2b raised at the bottom and an end plate 2c raised at the rear end of the bottom plate 2a.
And one side of the mixing vessel 3 having side plates 3b, 3b raised up from both side edges of the square bottom plate 3a in parallel and an end plate 3c raised up at the rear end of the bottom plate 3a. At the distal end portion, they are closely overlapped with each other, and are pivotally attached to the central support portion 4 at a lower portion of the overlapped portion by a pivot 5 from a horizontal to an upright state.

At the rear end of each of the mixing vessels 2 and 3, the upper ends of telescopic rods 7 'and 8' of cylinders 7 and 8 whose lower ends are pivotally connected to the lower base 6 are pivotally connected.

[0011] Between the overlapping end portions of the bottom plates 2a and 3a of the mixing vessels 2 and 3, a concrete material 9 put into the inside and a sealing material 10 for preventing leakage of water cover the gap of the joint. Is attached.

Further, a pressing plate 11 for appropriately vibrating the concrete material 9 is fitted into the kneading tank 1.

The pressing plate 11 is a plate body which can be tightly fitted from above into the kneading tank 1 in which the mixing containers 2 and 3 facing each other are in a horizontal state. A vibrating body 14 is mounted on the cylinder 13 so as to be movable up and down.

A method of kneading hardened concrete or ordinary concrete with a small amount of water using the kneading tank 1 constructed as described above will be described. As shown in FIG. The concrete material 9 is put into the kneading tank 1 located in the above, and as shown in FIGS. 2 and 3, one side of the mixing vessel 2 is turned upright by the cylinder 7 so that the concrete material 9 in the other side is turned upside down. Put in the mixing container 3.

Thereafter, as shown in FIG. 4, the mixing vessel 2 in the upright state is returned to the horizontal state, and in this state, the pressing plate 11 is fitted into the mixing vessel 1 as shown in FIG.
The concrete material 9 contained in the mixing container on the other side is pressed from above and below while vibrating by 4 and pressed into the entire kneading tank 1.

Next, as shown in FIGS. 6 and 7, after the other mixing vessel 3 is turned upright by the cylinder 8, the concrete material 9 therein is put into the one mixing vessel 2. As shown in FIG. 8, the mixing vessel 3 on the other side is returned to a horizontal state, the pressing plate 11 is fitted into the mixing vessel 1 in the same manner as described above, and the mixing vessel on one side is vibrated by the vibrator 14. The concrete material 9 contained in the inside 2 is pressed from above and below to consolidate the entire kneading tank 1, and thereafter the above steps are repeated as necessary.

As described above, the concrete material 9 is alternately transferred to the mixing containers 2 and 3 so that the concrete material 9 is alternately divided into two parts and stacked one above the other. Then, the concrete material 9 is thinly rolled up and down in multiple layers, and is uniformly kneaded.

In other words, theoretically, for example, if the thickness of the concrete material 9 initially charged into the kneading tank 1 is 30 cm, and this is repeated 10 times by repeating the above cycle, the thickness of Becomes 0.03cm and 30 more
When stacked, the thickness of one layer is 2.8 × 10 ^-8 cm, which is about the thickness of a molecule of water.

As described above, the concrete material 9 can be kneaded uniformly and reliably regardless of the amount of water by repeating the cycle in which the concrete material 9 is divided into right and left and piled up and down to repeat the pressing.

[0020]

As described above, according to the present invention, various concrete materials, particularly concrete materials having a small amount of water, can be uniformly and reliably kneaded.
