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

[0002] Concrete mixing is a method of mixing cement, lime, water and other materials and stirring them evenly. With the rapid development of my country's construction industry, concrete mixers are widely used in my country's industrial, agricultural, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is increasing;

[0003] As shown in the reference case "A concrete mixing device for construction sites" announcement number "CN215920908U", when cleaning the inner wall of the mixing box, the limit rod moves downward, and the block is pressed by the limit groove, so that the end of the rotating arm close to the cleaning arm moves upward, and then the scraper contacts the inner wall of the mixing box, and the stirring motor drives the stirring rod to rotate to clean the inner wall of the mixing box. The rotating motor drives the dispersion disk to rotate to disperse the material and improve the stirring effect;

[0004] When a concrete mixing device is used, since the concrete raw materials all have a certain weight, the raw materials will settle downwards during mixing, which will affect the uniformity of the concrete, causing the lower layer of the concrete to be wetter and the upper layer to be drier, thus affecting the overall quality and strength of the concrete.

[0005] Therefore, a concrete mixing device for construction sites is proposed to solve the above problems. Utility Model Content

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme. A concrete mixing device for construction sites comprises: a mixing tank, a bracket is fixedly installed at the bottom of the mixing tank, a feeding frame is fixedly installed at one side of the mixing tank, and a discharging pipe is fixedly installed at one side of the mixing tank; a mixing and stirring mechanism, wherein the mixing and stirring mechanism is arranged inside the mixing tank for shaking and mixing concrete materials, wherein the mixing and stirring mechanism comprises a motor fixedly installed at one side of the mixing tank, a mixing assembly is arranged at one side of the motor, and a scraping assembly is arranged inside the mixing tank.

When in use, concrete raw materials can be poured into the mixing tank 1 through the feeding frame 2 for mixing and mixing, and when mixing and mixing, the motor 31 can be started to drive the mixing assembly 32 to mix the internal raw materials, and when mixing, the raw materials can be stirred up and down inside the mixing tank 1, so that the raw materials can be stirred more evenly and the mixing effect can be improved. When the mixing assembly 32 is used, the scraping assembly 33 can be driven synchronously, so as to reduce the adhesion of concrete to the inner wall of the mixing tank 1.

Through the rotation of the reciprocating screw 325, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. When stirring, the motor 31 rotates the driving rod 321 to drive the reciprocating screw 325 to rotate, and the reciprocating screw 325 and the driving block 326 to perform threaded motion, so that the driving block 326 can reciprocate on the surface of the reciprocating screw 325, and synchronously drive the driving sleeves 3214 on the upper and lower sides to move. When the driving sleeve 3214 moves, it synchronously moves the movable tube 322, so that the movable tube 322 can move up and down while the driven rod 321 rotates, allowing the movable tube 322 to move synchronously. The mixing tank 1 is provided with two guide plates 324, which are fixedly mounted on the inner wall of the mixing tank 1. The two guide plates 324 are provided on the inner wall of the mixing tank 1. The guide plates 324 are provided on the inner wall of the mixing tank 1. The guide plates 324 are provided on the inner wall of the mixing tank 1. The guide plates 324 are provided on the inner wall of the mixing tank 1.

The two connecting frames 329 are respectively slidably connected to the two guide plates 328. When the moving rod 327 moves, it can slide on the surface of the guide plate 328 through the connecting frame 329, so that the moving rod 327 is more stable when moving inside the mixing tank 1. A fixed plate 3210 is fixedly installed inside the movable tube 322, and a guide rod 3211 is fixedly installed on the surface of the fixed plate 3210. Two protective sleeves 3213 are arranged inside the movable tube 322. The two protective sleeves 3213 are respectively located on both sides of the fixed plate 3210, and the two protective sleeves 3213 are fixedly connected to the inside of the driving rod 321.The surface of the guide rod 3211 is penetrated by two springs 3212, and the other ends of the two springs 3212 are fixedly connected to the inside of the two protective sleeves 3213 respectively. When the movable tube 322 moves, the fixed plate 3210 can be synchronously driven to move, so that the guide rod 3211 drives the corresponding spring 3212 to deform toward the protective sleeve 3213.

The scraper 332 contacts the inner wall of the stirring tank 1, and when the moving rod 327 moves, the two driving plates 331 and the scraper 332 are synchronously driven to move on the inner wall of the stirring tank 1, so that when the moving rod 327 moves back and forth, the inner wall of the stirring tank 1 is cleaned synchronously to reduce the adhesion of raw materials. The scraping assembly 33 also includes scraping rings 333 fixedly mounted on both ends of the movable tube 322, and the two scraping rings 333 are in contact with the surface of the driving rod 321. When the movable tube 322 moves, the scraping rings 333 at both ends can be used to clean the debris on the surface of the driving rod 321, so that the movement of the movable tube 322 is more stable and smooth.

[0026] When the utility model is in use, during stirring, the motor 31 rotates the driving rod 321 to drive the reciprocating screw 325 to rotate, and the reciprocating screw 325 and the driving block 326 perform threaded motion, so that the driving block 326 can reciprocate on the surface of the reciprocating screw 325, and synchronously drive the driving sleeves 3214 on the upper and lower sides to move. When the driving sleeve 3214 moves, the movable tube 322 is moved synchronously, so that the movable tube 322 can move up and down while the driven rod 321 is rotated, and the movable tube 322 synchronously drives multiple stirring rods 324 to stir and shake the raw materials up and down, ensuring that the raw materials can be evenly distributed in the mixing tank 1. This reciprocating motion not only increases the contact opportunities of the various components during the mixing process, but also effectively prevents the sedimentation and agglomeration of the materials by shaking up and down, thereby improving the uniformity and overall quality of the concrete. When stirring, the two stirring rods 324 are set in a V shape, and the stirring rods 324 rotate and move upward. When the movable tube 322 moves downward, cross flow is generated. Such a flow pattern can increase the collision and friction between the materials, thereby achieving more thorough mixing. When the movable tube 322 moves, the fixed plate 3210 can be driven to move synchronously, so that the guide rod 3211 drives the corresponding spring 3212 to deform toward the protective sleeve 3213. When the driving sleeve 3214 is not in contact with the movable tube 322, the movable tube 322 can be synchronously reset by the reset of the spring 3212, so that the movable tube 322 can continuously reciprocate on the driving rod 321, and when the moving rod 327 moves, the two driving plates 331 and the scraper 332 are synchronously driven to move on the inner wall of the stirring tank 1, so that when the moving rod 327 reciprocates, the inner wall of the stirring tank 1 is cleaned synchronously to reduce the adhesion of raw materials. When the movable tube 322 moves, the scraper rings 333 at both ends can be used to clean the debris on the surface of the driving rod 321, so that the movement of the movable tube 322 is more stable and smooth.
