Description

[Detailed Description of the Invention] The present invention efficiently and quickly mixes concrete materials such as gravel, sand, cement, etc. with water, and produces concrete suitable for kneading fast-acting cement with a reduced amount of water. This relates to kneading and conveying equipment.

Conventionally, concrete materials such as gravel, sand, and cement are transported to the site where the concrete will be poured, and then those materials are mixed with water at the site, where the required amount of concrete is dug and placed at the specified location. Concrete mixing and conveying equipment is known, but in such equipment it is desirable that the concrete material and water be mixed quickly and thoroughly. Since the kneading is carried out by the rotation of a screw provided inside the kneading machine, there was a problem in that the desired kneading could not be achieved.

In view of the above, it is an object of the present invention to provide a concrete drilling and conveying device with a simple structure, which can quickly and uniformly mix concrete material and water.

Hereinafter, embodiments of the present invention will be explained with reference to the drawings.
On the body frame 1 of the car cocoon V, the Bethel 2 is attached to the pivot shaft 3.
It is mounted around the neck with a lift cylinder 4 so that the neck can be tilted backwards.

A hawk bran container 5 of the concrete mixing and conveying device of the present invention is attached to the rear lower end of the vessel 2 so as to be able to rise and fall. The kneading container 5 is
It can be raised and rotated. As shown in the solid line in FIG. 1, if the vessel 2 is placed in a state where the thickening vessel 5 is extended, concrete materials such as gravel, sand, cement, etc., which are accommodated in the vessel 2, are woven into the mixing vessel 5. This is carried in by those eyes. Next, while the vessel 2 is tilted as shown in the line in Figure 1), water is supplied into the mixing container 5 through the water supply pipe 7, and the concrete is kneaded and transported by a concrete mixing and transporting device as described later. can. Next, the concrete kneading and conveying apparatus of the present invention will be explained with reference to FIGS.

A frame-like frame 26 is attached to the upper surface of the entrance of the kneading container 5 to prevent concrete from flowing out from the opening edge of the kneading container 5.

In the figure, 27 and 28 are Nada Azusa cars, and 29 and 30 are quantitative discharge feeders.

Next, the operation of the embodiment of the present invention will be explained. After the telescopic cylinder 6 is extended to extend the mixing container 5, the concrete material is fed into the mixing container 5 by the mirror tilt of the vessel 2, and then the prime mover 16 , 17, the second,
When the fourth kneading shafts S2 and S4 are both rotated synchronously in the right direction, the first, third and fifth kneading vessels S, S3 and S5 are rotated in the left direction through the transmission gear groups 18 to 22. Rotate.

Also, water is supplied into the kneading container 5 from the water supply pipe 7. In this case, the water supply port of the water supply pipe 7 is connected to the third mixing shaft S3 rather than the second kneading shaft S2.
Since it is on the side, there is a water-free concrete material around the first kneading axis S,. First, concrete materials such as gravel, sand, and cement that have entered the base of the kneading container 5 are rotated in the right direction of the first kneading shaft S, and the left and right centering blades 231, 231 attached thereto are... , 23r
, 23r, . The concrete material sent to the second kneading shaft S2 is mixed with water from the water supply pipe 7, and is mixed with the water from the water supply pipe 7 by rotating the second to fourth kneading shafts S2, S3, and S4 to the left, right, and right. The attached central and left stone sea bream cutting blades 24c, 241, and 24r give deep push and pull action to the left and right in the axial direction of these shafts, and the mixture is efficiently kneaded and transferred to the second kneading shaft S.
2, the material is fed into the fifth moat kneading shaft through the third and fourth kneading shafts S3 and S4. Finally, the mixed concrete that has reached the fifth mixing shaft S5 is further transferred to the central, left, and right folding blades 2.
5c, 251, and 25r, the wires are crossed, and are gathered into the center of the ball S5 and raised toward the exit 9. When the kneading container 5 is filled with concrete above the lower edge level of the carry-in port 9, the amount of concrete input through the carry-in port 8 is carried out from the carry-in port 9. The concrete materials and water are sufficiently kneaded by the first to fifth kneading shafts S, . and water become homogeneous, and high-quality concrete can be quickly mixed and produced. This is particularly effective when sufficiently mixing quick-acting cement, which is made to harden quickly by mixing a small amount of water. Furthermore, by forming the bottom wall 10 of the mixed twill container 5 with an elastic plate 11,
By eliminating the jamming of the concrete material between the bottom wall 10 and each blade 23, 24, 25, the cement is removed from the bottom wall 1.
You can go to the river. As described above, according to the present invention, a plurality of kneading shafts are horizontally suspended in a kneading container, a center blade is provided on the kneading shaft on the inlet side of the container, a folded blade is provided on the kneading shaft on the outlet side, and furthermore, A cutting blade was attached to each of the intermediate kneading shafts in between, and these kneading shafts were forcibly driven to rotate, so each concrete material contained in the kneading container was transported through the internal conveyance path from the entrance to the exit. While the concrete is being sent to the concrete plate, the actions of filling, cutting, pushing and pulling, and folding are sequentially applied as described above, and each material and water are quickly and uniformly mixed into a bran, resulting in high-quality ready-mixed concrete. It is extremely effective for mixing fast-acting cement that hardens early, especially when the amount of water mixed is small.
