Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was developed for various types of concrete mixing equipment, mainly for hard mixing concrete with a small amount of water. This invention relates to a kneading device suitable for cleat.

0002

[Conventional technology]

The conventional method of mixing concrete involves rotating a tilted mixing drum. A method of stirring the concrete material placed inside the container using gravity, or is a method of forcibly stirring the concrete material put into a tank or pipe using a stirring blade. law is exclusively adopted.

0003 However, according to the above conventional method, relatively soft concrete material with a large amount of water cannot be used. If it is a raw material, it can be kneaded relatively easily and uniformly due to its fluidity, but Hard concrete materials with a small amount of water have poor fluidity, so stirring blades etc. It was difficult to knead uniformly.

0004

[Problem that the idea aims to solve]

This idea makes it possible to uniformly mix hardened concrete materials with a small amount of water. The goal is to solve difficult problems.

[0005]

[Means to solve the problem]

This invention solves the above-mentioned conventional problems by Side plates 2b, 3b stand up in parallel from A pair of mixing containers 2 and 3 having plates 2c and 3c are stacked at their mutual ends. and is rotatably pivoted to the central support part 4 at the lower part of the overlapping part. The kneading tank 1 is pivotally connected between the rear ends of the mixing vessels 2 and 3 and the lower base 6, and the front Directly lift each mixing container 2, 3 upward from a horizontal position centering on the pivot point of the central support 4. The cylinders 7 and 8 rotate alternately in an upright position, and the mixing containers 2 and 3 are in a horizontal position. It is a plate that can be fitted into the kneading tank 1 from above, and is supported by the lifting cylinder 13 so that it can be raised and lowered. The concrete is made up of This paper proposes a kneading device for the first time.

[0006]

[Effect]

Concrete material 9 is put into the mixing tank 1 in which the mixing containers 2 and 3 are in a horizontal state, The mixing container 2 on one side is rotated to an upright state by the cylinder 7, and the concrete inside is After filling the mixing container 3 on the other side with the mixed material 9, place the mixing container 2 on the one side horizontally. restore the condition.

[0007] In this state, the press plate 11 is inserted into the mixing tank 1, and the vibration is generated by the vibrating body 14. While feeding the concrete material 9 contained in the mixing container 3 on the other side in the vertical direction Pressure is applied to the entire mixing tank 1.

[0008] Next, the mixing container 3 on the other side is rotated to an upright state by the cylinder 8, and the inside of the mixing container 3 is rotated to an upright state. After the concrete material 9 is loaded into the mixing container 2 on one side, it is poured into the mixing container 2 on the other side. 3 to the horizontal state, similarly fit the pressing plate 11 into the mixing tank 1, and press the vibrating body 14. The concrete material contained in the mixing container 2 on one side while being vibrated by 9 from above and below to apply pressure to the entire mixing tank 1, and repeat the above steps as necessary. By turning, the concrete material with a small amount of water is mixed uniformly.

【Example】

Figures 1 to 9 show the mixing device according to this invention and the mixing of concrete materials using this device. The kneading tank 1 has a rectangular box shape, and the kneading tank 1 has a square bottom plate 2a with both sides of the bottom plate 2a. The side plates 2b, 2b stand up parallel to each other, and the end plate 2c stands up at the rear end of the bottom plate 2a. and a mixing container 2 on one side having A mixture of one side having side plates 3b, 3b and an end plate 3c raised up from the rear end of the bottom plate 3a. The containers 3 are placed opposite each other, and their mutual tips are overlapped closely to form the overlapping portion. It can be freely rotated from a horizontal to an upright position by a pivot 5 on a central support part 4 at the bottom of the It is pivoted to.

0010 At the rear end of each of the mixing containers 2 and 3 is a series whose lower ends are pivotally connected to the lower base 6. The upper ends of telescopic rods 7' and 8' of the undercarriages 7 and 8 are pivotally connected.

[0011] Between the overlapping tops of the bottom plates 2a and 3a of each mixing container 2 and 3, there is a Cover the gaps between seams to prevent leakage of concrete material 9 and water poured inside. A sealing material 10 is attached for this purpose.

0012 Also, in this mixing tank 1, there is a press for vibrating and compressing the concrete material 9 as appropriate. A pressure plate 11 is fitted.

[0013] The pressing plate 11 is placed upward in the kneading tank 1 in which the opposing mixing vessels 2 and 3 are in a horizontal state. It is a plate body that can be tightly fitted between It is supported by an elevating cylinder 13 so as to be able to rise and fall freely, and a vibrating body 14 is installed at the top. Ru.

[0014] Using the mixing tank 1 configured as described above, hardened concrete with a small amount of water can be mixed. To explain how to mix ordinary concrete, as shown in Figure 1, Concrete material 9 is placed in a mixing tank 1 with mixing containers 2 and 3 facing each other in a horizontal state. As shown in Figures 2 and 3, the mixing container 2 on one side is held upright by the cylinder 7. The concrete material 9 inside the concrete material 9 is loaded into the mixing container 3 on the other side.

[0015] Thereafter, as shown in FIG. 4, the upright mixing container 2 is returned to the horizontal state, and In this state, as shown in FIG. 5, the pressing plate 11 is inserted into the mixing tank 1, and the While applying more vibration, the concrete material 9 contained in the mixing container on the other side is Pressure is applied from above and below to the entire kneading tank 1.

[0016] Next, as shown in FIGS. 6 and 7, the mixing container 3 on the other side is held upright by the cylinder 8. The concrete material 9 therein was poured into the mixing container 2 on one side. After that, as shown in Fig. 8, return the mixing container 3 on the other side to the horizontal state, and proceed as above. A pressing plate 11 is inserted into the mixing tank 1, and one side is heated while being vibrated by the vibrating body 14. The concrete material 9 contained in the mixing container 2 is pressed from above and below to form a kneading tank. 1, and then repeat the above steps as necessary.

[0017] In this way, the concrete material 9 is alternately transferred to the mixing containers 2 and 3. Therefore, the concrete material 9 is alternately divided into two parts and stacked one on top of the other, and this is pressed. By vibrating and compressing the plate 11, the concrete material 9 is sequentially layered vertically. The mixture is compressed into a thin layer and kneaded uniformly.

In other words, theoretically, for example, if the thickness of the concrete material 9 initially put into the mixing tank 1 is 30 cm, if the above-mentioned cycle is repeated 10 times, the thickness of the concrete material 9 becomes one layer. becomes 0.03 cm, and if they are stacked 30 more times, the thickness of each layer will be 2.8 x 10 ^-8 cm, about the thickness of a water molecule.

[0019] In this way, the concrete material 9 is divided into left and right parts and piled up and down. By repeating the cycle, no matter the amount of water in the concrete, it will be uniform. And it becomes possible to knead reliably.

[0020]

[Effect of the idea]

As mentioned above, according to this invention, various concrete materials, especially concrete with a small amount of water, can be used. Cleat materials can also be kneaded uniformly and reliably.
