Description

Technical Field

[0001] The utility model relates to the technical field of concrete homogenizing equipment, in particular to a concrete homogenizing device for building construction. Background Art

[0002] Concrete homogenizing devices are equipment used in the concrete production process to ensure the mixing and homogenization of concrete raw materials. These devices include mixers, mixer trucks, concrete mixing plants, mixing rods, concrete mixing drums and concrete mixing machinery. Their role is to ensure the uniform distribution of concrete ingredients and ensure the quality and stability of concrete during transportation and construction.

[0003] A vertical concrete mixer disclosed in Chinese patent publication number CN219325372U can not only mix concrete at the inner corners of the mixing barrel, but also make the mixing effect of the concrete more uniform through the cooperation of a support frame, a mixing barrel, a through-hole boss, a rotating fixed platform, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, an elastic block, an inner scraper, a middle scraper, an outer scraper, a first drive motor, a rotating mixing blade, a discharge port, a movable panel door, a hinged seat, a control handle, a supporting beam, a right-angle transmission device, a second drive motor, a transmission shaft, a first pulley, a second pulley and a transmission belt.

[0004] However, compared with the existing technology in the related field, when using it, firstly, in order to ensure the operation of the rotating stirring blades, it is necessary to set a motor to rotate synchronously with the transmission shaft. If the motor is powered by wires during implementation, the wires are prone to entanglement, resulting in the equipment being unable to operate. If the motor is powered by a battery, it needs to be charged regularly, and the overall production cost of the equipment and the subsequent maintenance cost will also increase accordingly. Secondly, the material cannot form a strong shear, extrusion, tumbling and kneading state, making it difficult to mix the material evenly, increasing the mixing time and reducing the production efficiency.

[0029] like Figure 1-4 As shown, a concrete homogenizing device for construction includes a mixing drum 1, a rotating shaft 2 is rotatably provided at the center of the mixing drum 1, stirring components 3 are equidistantly provided on the outer surface of the rotating shaft 2, and a power component 4 is provided on the rotating shaft 2; the power component 4 includes a fixed plate 401 fixedly installed on the top of the rotating shaft 2, and a stirring mechanism 5 is axially slidable and circumferentially rotated at one end of the fixed plate 401 away from the rotating shaft 2, and the stirring mechanism 5 is used to provide upward turning force and downward pressure to the material, and a gear 402 for controlling the rotation of the fixed plate 401 is rotatably provided on the side close to the stirring mechanism 5, and a gear ring 6 meshing with the gear 402 is fixedly provided on the inner wall of the mixing drum 1 corresponding to the position of the gear 402, and a plurality of protrusions 7 for controlling the axial sliding of the stirring mechanism 5 are fixedly provided on the bottom surface inside the mixing drum 1.

[0030] The stirring assembly 3 includes a fixed shaft 301 fixedly arranged on the outer surface of the rotating shaft 2, a fixed block 302 is fixedly arranged at one end of the fixed shaft 301 away from the rotating shaft 2, a connecting rod 303 is longitudinally arranged at the center of the fixed block 302, and a scraper 304 is fixedly installed at the bottom end of the connecting rod 303. The scraper 304 can squeeze the concrete inside the mixing drum 1 toward the outside, thereby improving the working effect of the stirring mechanism 5.

[0031] A sleeve 403 is fixed at the center of the gear 402, and a rotating hole is opened at the position of the fixed plate 401 corresponding to the sleeve 403. The sleeve 403 is connected to the rotating hole through a bearing. The bearing is used to reduce the friction force of the gear 402 during rotation, thereby ensuring the stability of the gear 402 during rotation.

[0032] The mixing mechanism 5 includes a movable rod 501 that longitudinally slides with the sleeve 403. The outer surface of the movable rod 501 is fixed with a plurality of spiral paddles 502 for providing an upward force to the material. The outer surface of the movable rod 501 is fixed with a plurality of pressure plates 503 for providing a downward pressure to the material. The plurality of pressure plates 503 are all inclined, and the inclination angle is between thirty and sixty degrees. A rectangular column 504 is fixed at the top of the movable rod 501. The center of the sleeve 403 is a quadrilateral slot 4031, and the rectangular column 504 is adapted to the quadrilateral slot 4031.

[0038] S3, when the movable rod 501 rotates, the spiral belt paddle 502 of the stirring mechanism 5 will provide an upward force to the material, and the pressing plate 503 will provide a downward pressure to the material, thereby improving the axial circulation and radial mixing of the concrete during stirring;

When the movable rod 501 is separated from the protrusion 7, under the action of gravity, the movable rod 501 can drive the spiral paddle 502 and the pressure plate 503 to slide downward, thereby utilizing the up and down reciprocating sliding of the movable rod 501 to enrich the stirring trajectory, so as to improve the shearing, squeezing, tumbling and kneading state of the material.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model.
