Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 to 4, the concrete mixing equipment comprises a vertical multi-shaft mixer 1, a layered material receiving bin 2 and a transportation bin 12; the vertical multi-shaft stirrer 1 is fixed on the upper floor of a building through a high-foot support, and a layering material receiving bin 2 is also arranged on the floor; the layered material receiving bin 2 is positioned below the vertical multi-shaft stirrer 1 and is used for receiving materials in the vertical multi-shaft stirrer 1.

When the vertical multi-shaft mixer 1 is used for mixing, the heavy aggregate is sunk, and the light cement is located in the upper layer. Therefore, the lower part is heavy material containing more aggregate, and the upper part is light material containing less aggregate.

In this embodiment, as for the structure of the layered material storage bin 2, as shown in fig. 2: the lower heavy material cavity 201 and the upper light material cavity 202 are separated by an openable and closable opening and closing door panel A3. The heavy material cavity 201 and the light material cavity 202 are respectively communicated with a material pipe A4 and a material pipe B5, the two cavities respectively feed materials through corresponding flood dragon shafts A, a vertical pipe 6 is arranged at the outlet of the material pipe A4, and an inclined pipe 7 is arranged at the outlet of the material pipe B5; the outlet of the inclined pipe 7 is communicated with the wall of the vertical pipe 6 to form a structure for reuniting heavy materials and light materials.

In the scheme, a transportation bin 12 is arranged below an outlet of the vertical pipe 6, and the transportation bin 12 sends the collected weight and light materials to the distributing machine; the transportation bin 12 is arranged on the track through a sliding block 13, a switch door B14 which is used for receiving materials and can be opened and closed is arranged on the transportation bin 12, and a material leakage port corresponding to the switch door B14 is arranged on the sliding block 13.

Further, the material conveying bin 12 is in a horizontally arranged barrel shape, and a switch door B14 is arranged on the cylindrical surface of the material conveying bin; the transportation bin 12 is rotatably arranged on the sliding block 13 through a rotating shaft and a mounting lug, and the rotating shaft is connected with the self-locking overturning motor 15 to form an overturning structure; the heavy and light materials can be further mixed in the transport silo 12. The transportation bin 12 is also provided with a stirring shaft and a corresponding stirring motor 16.

The working principle comprises the following steps:

after the materials in the vertical multi-shaft stirrer 1 are stirred, the outlet is opened, the heavy materials at the lower part firstly leak down, and the switch door plate A3 is opened at the moment, so that the heavy materials are positioned in the heavy material cavity 201; when the heavy material leaks to a certain degree, the door panel A3 is closed through the switch, and then the light material cavity 202 is used for the light material.

Finally, the heavy materials and the materials are respectively conveyed through a material pipe A4 and a material pipe B5 and finally are collected in the vertical pipe 6. According to the structure, when the heavy material and the light material are converged, the speed of the light material is higher, so that the heavy material is gradually mixed into the light material.

Then the mixed heavy materials and light materials enter the transportation bin 12 together, the rear switch door B14 is closed, the self-locking turnover motor 15 drives the transportation bin 12 to rotate and roll, and the stirring motor 16 works in the rotating and rolling process, so that the heavy materials and the light materials are further mixed. Because the transportation barrel 12 is in an inverted state, the situation that heavy materials are gathered at the bottom of the transportation barrel 12 does not exist, and therefore the uniform mixing of the heavy materials and the light materials is further ensured. When the material is distributed, the uniform mixing of the concrete can be ensured, thereby ensuring the preparation quality of the prefabricated member.

In this embodiment, the switch door panel a3 is formed by two arc-shaped plates 301, so that the bottom of the light material cavity 202 is arc-shaped; the bottom of the heavy material cavity 201 is also arc-shaped; arc-shaped grooves 203 are formed in two side walls of the layering storage bin 2, arc-shaped pieces 8 are arranged on the outer sides of the arc-shaped grooves 203, and the arc-shaped pieces 8 are connected with the arc-shaped plates 301 through connecting rods 9; the arc-shaped piece 8 is meshed with a gear 10, and the gear 10 is driven by a corresponding door driving motor to form a structure for driving the opening and closing of the door panel A3. That is, the bottom of the light material chamber 202 is formed into an arc shape, which is beneficial to feeding.

In this embodiment, the flood dragon axis a correspondingly extends into the material pipe a4 and the material pipe B5. Consequently flood dragon axle A's length is longer, needs both ends all to support just can guarantee the intensity requirement, and this structural design is shown in FIG. 2 for this reason: a flood dragon shaft B is arranged at the end of the material pipe A4 and the end of the material pipe B5; flood dragon axle B and flood dragon axle A push away the material opposite direction, and corresponding vertical pipe 6, inclined pipe 7 are set up to the department that converges between them.
