Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a concrete mixing device, including a mixing bucket 1, a bucket cover 2, and a mixing assembly 4. A mounting frame 3 is bolted to the bucket cover 2. The mixing bucket 1 is used to contain the concrete raw materials to be mixed and to provide a mixing space. The bucket cover 2 is bolted to the opening of the mixing bucket 1. A feed hopper 5 is connected to the bucket cover 2. A discharge pipe 6 is connected to the bottom of the mixing bucket 1. A valve is installed on the discharge pipe 6. The feed hopper 5 is used to add concrete raw materials into the mixing bucket 1, and the discharge pipe 6 is used to discharge the mixed concrete.

[0024] The stirring assembly 4 is mounted on the mounting frame 3. The stirring assembly 4 includes a cylinder 401 and a gear ring 405. Two bushings 402 are rotatably fitted on the cylinder 401. The cylinder 401 acts as the drive shaft, transmitting clockwise power to the first gear 406 and the first stirring blade 409. Connecting plates 403 are bolted to opposite sides of the bushings 402. Support columns 404 are bolted to the connecting plates 403. The bottom of the gear ring 405 is bolted to the two support columns 404. The first gear 406 is connected to the cylinder 401 via a key. A connecting column 407 is bolted to the mounting frame 3. A second gear 408 is connected to the connecting column 407 via a bearing. 8 meshes with the first gear 406, and the second gear 408 meshes with the gear ring 405. The first gear 406 can drive the second gear 408 to rotate counterclockwise, and the second gear 408 can drive the gear ring 405 to rotate synchronously. The first stirring blade 409 is bolted on the cylinder 401, and the second stirring blade 410 is bolted on the connecting plate 403. The first stirring blade 409 and the second stirring blade 410 are arranged alternately. The first stirring blade 409 rotates clockwise with the cylinder 401, directly shearing and breaking up the material. The second stirring blade 410 rotates counterclockwise with the connecting plate 403, forming an alternating stirring, covering more areas in the mixing tank 1, avoiding dead corners in the stirring, and improving the homogeneity of the concrete.

[0025] The mounting frame 3 has a connection hole 301. The cylinder 401 is rotatably engaged with the connection hole 301 through a bearing. One end of the cylinder 401 passes through the connection hole 301 and is connected to the power output shaft of the drive source through a coupling. The drive source is a suitable three-phase asynchronous motor. The three-phase asynchronous motor is mounted on the L-shaped plate with bolts. The L-shaped plate is mounted on the top of the mounting frame 3 with bolts.

[0026] Both the first stirring blade 409 and the second stirring blade 410 have serrated edges. The serrated edges can cut up lumpy materials and improve the uniformity of mixing. A scraper 411 is bolted on the connecting plate 403. The scraper 411 abuts against the inner wall of the mixing tank 1. The scraper 411 rotates synchronously with the connecting plate 403. The scraper 411 is used to scrape off the material adhering to the inner wall of the mixing tank 1 to prevent the material from sticking to the wall and hardening.

[0027] The two bushings 402 are arranged in parallel, and the connecting plate 403 is arranged in a U-shaped rod shape. The two extended ends of the U-shaped rod of the connecting plate 403 are respectively installed on the outer walls of the upper and lower bushings 402 by bolts.

[0028] The bucket lid 2 has a through hole 201. The outer wall of the support column 404 slides against the inner wall of the through hole 201. The through hole 201 is used to prevent the support column 404 from being obstructed when rotating. The gear ring 405, the first gear 406 and the second gear 408 are all coated with anti-rust paint. At the same time, the material is added according to the actual situation. The height of the material will not be too high to ensure that the height of the splash when the material is stirred will not affect the gear ring 405, the first gear 406 and the second gear 408.

[0029] During operation, cement, sand, water, and other raw materials are first added to the mixing tank 1 through the feed hopper 5. Then, the three-phase asynchronous motor is started through the external controller. The power output shaft of the three-phase asynchronous motor drives the cylinder 401 to rotate clockwise. The cylinder 401 drives the first gear 406 to rotate clockwise synchronously. The first gear 406 drives the second gear 408 to rotate counterclockwise. The second gear 408 drives the gear ring 405 to rotate synchronously. The gear ring 405 drives the connecting plate 403 to rotate synchronously through the support column 404. At this time, the first mixing blade 409 rotates clockwise with the cylinder 401, and the second mixing blade 410 rotates counterclockwise with the connecting plate 403, working together to mix the materials. The serrated edges can cut up lumps of materials. The scraper 411 rotates with the connecting plate 403 to scrape off the materials adhering to the inner wall of the mixing tank 1. After mixing is completed, the discharge pipe 6 valve is opened, and the materials are discharged through the discharge pipe 6, thus completing the concrete mixing work.
