Description

Technical Field

[0001] The present invention relates to the technical field of concrete manufacturing, and in particular to concrete manufacturing equipment and a control method thereof. Background Art

[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and then mixed with water (which may contain admixtures and additives) in a certain proportion. The mixture obtained by stirring is cement concrete. With the rapid advancement of urbanization, the amount of engineering projects in cities is increasing, and the use of concrete is gradually increasing.

[0003] At present, most concrete processing methods are to mix and evenly mix them through mixers. In this operation, concrete is prone to caking problems. Generally, the caking problem in the concrete mixing process is solved by extending the mixing time. However, the mixing operation is carried out by rotating multiple mixing rollers. Therefore, even under long-term mixing operations, the relatively firmly solidified concrete blocks will still rotate with the water flow and cannot be mixed evenly. At this time, the staff needs to manually break them up.

[0004] Although the above-mentioned solution to the agglomeration problem during concrete mixing is simple and easy to operate, it will waste a lot of time for the preparation of concrete and requires manpower to supervise and assist the concrete mixing process, which not only reduces the manufacturing efficiency of concrete, but also causes delays in the progress of the project.

The guide rod 47 passes through the inner wall of the cavity 45 near the vertical groove 44 and extends into the vertical groove 44 and is slidably connected to the fixed ring 35. The end of the guide rod 47 is pressed and fitted with the upper part of the movable rod 3, and the top surface of the clamping block 48 is pressed and fitted with the bottom surface of the movable ring 34. A compression spring 49 is fixed between the clamping block 48 and the inner wall of the cavity 45, and a clamping groove 50 is provided on the inner wall of the movable ring 34 to clamp and fit with the clamping block 48.

[0043] Working principle: In the preparation stage, the staff needs to connect the external water source and the output end of the feed pump used to supply concrete powder to the water inlet pipe 10 and the feed pipe 11 in the device respectively. The ends of the two far away from the outer tube 1 are connected with flanges and corresponding seals to facilitate the staff to connect them with external equipment. At this time, the water inlet pipe 10 and the feed pipe 11 are blocked by the sealing plate 25, and the movable ring 34 is supported by the elastic force of the support spring 38 and will be at the highest point. The ratio of the inner diameters of the two pipes is equal to the ratio of water and powder used in concrete manufacturing. At the same time, the ratio of powder and water flowing into the device must meet the production requirements;

[0044] After the preparation work is completed, the staff can start the motor 31 to drive the driving disk 27 to rotate at a constant speed, and then the multiple tooth columns 29 on the driving disk 27 will drive the turntable 6 to rotate through the tooth grooves 30, and the turntable 6 will squeeze the upper end of the movable rod 3 through the first guide groove 32 and the second guide groove 33, and then make it produce a linear reciprocating movement under the limiting effect of the movable groove 24. The tooth columns 29 are provided with a specified number, and the number is just enough to make the movable rod 3 move from the outside to the inside or from the inside to the outside under the drive of the turntable 6, so that it is at the innermost or outermost end of the movable groove 24 when the tooth columns 29 and the tooth grooves 30 are not engaged. The former is to provide sufficient time for feeding and water entry, and the latter is to provide sufficient time for the raw materials on the movable ring 34 to enter the inner cylinder 14;

[0045] During the inward movement of the movable rod 3, its lower end will pull the metal cable 37 to move inward, and then the metal cable 37 will prompt the movable ring 34 to overcome the elastic force of the supporting spring 38 and move downward, and then the movable ring will first contact the support plate 41, and then the baffle 39 will be moved out of the bottom groove 40 by pressing down the support plate 41 (the top surface of the baffle 39 relative to the inside of the two pipes is provided with a semi-cylindrical through groove consistent with the inner diameter of the two pipes. When the baffle 39 drops to the lowest point, the bottom surfaces of the two grooves are respectively flush with the inner bottom surfaces of the two pipes. Such a structure can prevent materials from pouring into the groove where the baffle 39 is located). At this time, the inside of the water inlet pipe 10 and the material inlet pipe 11 will be converted into a through state, and the external materials and water will pour into the gap between the outer cylinder 1 and the inner cylinder 14 from the two and move with the movement of the movable ring 34, and the movable rod 3 moves in position. Before reaching the innermost end of the movable groove 24, the bottom surface of the movable ring 34 will squeeze the top inclined surface of the block 48 and make the block 48 retract into the cavity 45 by overcoming the elastic force of the compression spring 49. When the position of the slot 50 on the movable ring 34 moves to the position of the block 48, the compression spring 49 will push it out and snap it into the slot 50 so that the position of the movable ring 34 cannot rise. The height of the lower opening end of the cavity 45 is lower than the height of the inner wall of the movable ring 34. When the movable ring 34 is at the lowest position, the lower opening end of the cavity 45 will not be connected with the space above the movable ring 34, so there will be no problem of powder or water entering the cavity 45. When the block 48 is located outside the cavity 45, the rotating rod 46 is in a vertical state, and the guide rod 47 at the upper end of the rotating rod 46 will extend into the vertical groove 44. This state is maintained by the elastic force of the compression spring 49, and the movable ring 34 cannot move up without external force.

[0046] During the outward movement of the movable rod 3, the pulling force of its lower end on the metal cable 37 will disappear. However, the movable ring 34 at this time is restricted by the engagement of the block 48 and the slot 50. Therefore, the support spring 38 cannot lift the movable ring 34. Only after the movable rod 3 is re-engaged with the vertical slot 44, the outer wall of the movable rod 3 will squeeze the guide rod 47, thereby causing it to enter the cavity 45, and then the rotating rod 46 will be squeezed into an inclined state again, and the block 48 at its lower end will be pulled into the cavity 45 again under the drive of the rotating rod 46. Subsequently, the movable ring 34 without the restriction of the block 48 will rise to its original position under the elastic force of the support spring 38, and the partition plate 39 will also rise synchronously with it. The partition plate 39 will pull the two pipes together again. The movable ring 34 is sealed for the second time to stop the injection of external raw materials. During the rising process, the powder and water simply mixed on the top surface of the movable ring 34 will be gradually poured into the inner cylinder 14 from the feed groove 36. The top surface of the movable ring 34 is designed as a slope structure with a low inside and a high outside, which is more convenient for the raw materials to flow toward the inner cylinder 14. With such a design, it can be ensured that the movable ring 34 will inject the raw materials into the inner cylinder 14 only after the movable rod 3 is inserted into the vertical groove 44, and it is ensured that all the raw materials are mixed on the inner side of the multiple baffles 4. In addition, the powder and water can be gradually added to the outer cylinder 1 through the multiple up and down movements of the movable ring 34, avoiding the large-area agglomeration problem easily caused by a large amount of powder and water being put in at one time, reducing the difficulty of stirring and the possibility of agglomeration;

[0047] During the inward movement of the movable rod 3, the baffle 4 thereon serves to intercept the concrete agglomerates, pushes them toward the direction of the rotating shaft 7 and cooperates with the external structure of the rotating shaft 7 to break them up. On the other hand, during the continuous rotation of the turntable 6, the rotating shaft 7 coaxially fixedly connected to its bottom surface will also rotate synchronously, thereby driving the multiple extrusion plates 9 slidably connected on its outer wall to rotate. During the rotation, the semi-cylindrical end of the fixed plate 16 will continue to slide in contact with the outer wall of the extrusion rod 22. When the fixed plate 16 is at the position corresponding to the groove 23, it moves inward under the pulling force of the tension spring 20 and contacts with the groove 23. When the movable rod 3 is staggered, the extrusion plate 9 is squeezed outward by the outer wall of the extrusion rod 22. The reciprocating movement can stir the powder and water to make them fluid. The mixing effect can be achieved by cooperating with the reciprocating movable rod 3 and the baffle 4. At the same time, when the movable rod 3 moves to the innermost end, the extrusion plate 9 will move outward when corresponding to the baffle 4. Under the wave-shaped structure of its outer wall and the concave design, the agglomerated concrete is crushed and dispersed. When the extrusion plate 9 retracts, it corresponds to the position of the movable rod 3, and at this time, it is prevented from having a hard contact with the protruding movable rod 3.

[0048] Finally, the staff only needs to stop injecting the raw materials after injecting a certain amount of raw materials, and then use the device to fully stir and mix the raw materials already in the inner cylinder 14 to release them from the discharge pipe 12. The discharge pipe 12 can be opened and closed by the valve 13.
