During operation, the operator pours the concrete raw materials to be mixed into the conveying cylinder 12 through the feed pipe 13, and then starts the conveying component. The conveying component will slowly and evenly transport the concrete raw materials to the top of the mixing cylinder 14. At this time, the concrete raw materials will be transported into the mixing cylinder 14 in batches by the conveying component. Then the operator starts the crushing component and the mixing component. When the concrete raw materials enter the mixing cylinder 14, the crushing component will initially crush the concrete raw materials. The crushed concrete raw materials will be fully mixed by the mixing component inside the mixing cylinder 14. Then the mixed concrete inside the mixing cylinder 14 will be taken out through the discharge pipe 15.

[0025] like Figures 1 to 4As shown, the transport assembly includes a first motor 2; the first motor 2 is mounted on the side wall of the transport cylinder 12; a first movable shaft 21 is fixedly connected to the output end of the first motor 2; a spiral blade 22 is mounted in the middle of the side wall of the first movable shaft 21; the spiral blade 22 is located inside the transport cylinder 12; a limit rod 23 is rotatably connected to the middle of the inner side wall of the spiral blade 22; the other end of the limit rod 23 is fixedly connected to the transport cylinder 12; a second motor 24 is mounted on the top of the base 1; a movable cover 25 is fixedly connected to the output end of the second motor 24; the movable cover 25 is rotatably connected to the stirring cylinder 14. A feed inlet 26 is provided in the middle of the side wall of the movable cover 25; the feed inlet 26 is correspondingly provided with the conveying cylinder 12; during operation, the operator starts the first motor 2, which drives the first movable shaft 21 to rotate. When the first movable shaft 21 rotates, it drives the spiral blades 22 to rotate inside the conveying cylinder 12. After the concrete raw material enters the conveying cylinder 12 through the feed pipe 13, the spiral blades 22 will transport the concrete raw material towards the discharge end of the conveying cylinder 12. When the concrete raw material is transported to the top of the movable cover 25, the operator starts the second motor. 24. The second motor 24 drives the movable cover 25 to rotate. At this time, the movable cover 25 will reciprocate at the top of the mixing drum 14. When the inlet 26 on the side wall of the movable cover 25 is connected with the outlet of the conveying drum 12, the concrete raw material will pass through the movable cover 25 and enter the mixing drum 14.

Moreover, this setting adopts a closed structure, which can effectively reduce dust flying during the material transportation process and reduce the health hazards to operators. At the same time, the low-speed rotation of the spiral blade 22 can reduce noise and meet environmental protection requirements. By setting the second motor 24, the movable cover 25 and the inlet 26, the material can be fed into the mixing drum 14 in batches, reducing the problem of uneven mixing caused by adding too much material at once. In addition, by controlling the input of raw materials in batches, the mixing time can also be shortened and the energy consumption of the equipment can be reduced.

Then, the operator starts the third motor 3, which drives the second movable shaft 31 to rotate. When the second movable shaft 31 rotates, it drives the first crushing roller 32 inside the mixing drum 14. The first crushing roller 32 and the raw material rotate, while the second crushing roller 33 rotates inside the mixing drum 14. At this time, the raw material is pre-crushed under the combined action of the first crushing roller 32 and the second crushing roller 33. This step, by setting the third motor 3, the second movable shaft 31, the first crushing roller 32 and the second crushing roller 33, can effectively crush large particles of aggregate in the raw material, making the particle size of the raw material more uniform, reducing the problem of excessively high porosity in concrete caused by unreasonable gradation, thereby improving the density and strength of concrete. Moreover, the crushed concrete raw material is easier to mix evenly, which can shorten the mixing time, reduce the power requirements of the mixing device, and extend the equipment life.

[0027] like Figures 1 to 3 As shown, the stirring assembly includes a fourth motor 4; the fourth motor 4 is mounted at the bottom of the stirring drum 14; a third movable shaft 41 is fixedly connected to the output end of the fourth motor 4; multiple stirring plates 42 are fixedly mounted on the middle of the side wall of the third movable shaft 41; the multiple stirring plates 42 are staggered; multiple stirring rods 43 are fixedly connected to the middle of the side wall of the stirring plates 42; the stirring plates 42 and stirring rods 43 are all located inside the stirring drum 14; during operation, the operator starts the fourth motor 4, which drives the third movable shaft 41 to rotate, and the rotation of the third movable shaft 41 drives the multiple stirring plates 42. The mixing plate 42 rotates, and at this time, the multiple mixing rods 43 on the side wall of the mixing plate 42 will rotate inside the mixing drum 14. The mixing plate 42 and the mixing rods 43 will fully mix the concrete raw materials inside the mixing drum 14. This step, by setting the fourth motor 4, the third movable shaft 41, the mixing plate 42 and the mixing rods 43, can make the cement and water in the raw materials fully mixed, reduce the porosity and weak layers inside the concrete, improve the compressive strength of the concrete, and the uniformly mixed concrete raw materials can reduce the scrap caused by the substandard concrete performance, and save raw materials and transportation costs.

[0028] like Figure 1 and Figure 4As shown, a dustproof plate 5 is installed in the middle of the inner wall of the feed pipe 13; the dustproof plate 5 is made of deformable material; by setting the dustproof plate 5 on the side wall of the feed pipe 13, this step can prevent concrete raw materials from splashing due to impact force during feeding, reduce the raw materials from falling outside the equipment, reduce material waste, and the dustproof plate 5 and the feed pipe 13 form a semi-enclosed structure, which effectively reduces the dust overflow generated during the feeding process.

[0029] like Figure 1 and Figure 2 As shown, a shock-absorbing pad 6 is fixed to the bottom of the base 1; the shock-absorbing pad 6 is made of elastic material; this step can absorb the vibration energy of the stirring device by setting the shock-absorbing pad 6, reduce the vibration amplitude of the equipment, and reduce fatigue damage to the equipment.

[0030] like Figure 1 As shown, an observation window 7 is provided in the middle of the side wall of the mixing drum 14; the observation window 7 is made of transparent material; by setting the observation window 7, the state of the concrete inside the mixing drum 14 can be observed in real time, reducing equipment overload or idling caused by uneven mixing, and reducing equipment energy consumption and carbon emissions.

[0031] Working Principle: The operator pours the concrete raw materials to be mixed into the conveying cylinder 12 through the feed pipe 13, and then starts the conveying assembly. The conveying assembly slowly and evenly transports the concrete raw materials to the top of the mixing cylinder 14. At this time, the concrete raw materials are transported into the mixing cylinder 14 in batches by the conveying assembly. Then, the operator starts the crushing assembly and the mixing assembly. When the concrete raw materials enter the mixing cylinder 14, the crushing assembly will initially crush the concrete raw materials. The crushed concrete raw materials will be fully mixed by the mixing assembly inside the mixing cylinder 14. Then, the mixed concrete inside the mixing cylinder 14 is taken out through the discharge pipe 15. The operator starts the first motor 2, which drives the first movable shaft 21 to rotate. When the first movable shaft 21 rotates, it drives the spiral blades 22 to rotate inside the conveying cylinder 12. When the concrete raw materials enter the conveying cylinder 12 through the feed pipe 13, the spiral blades 22 will transport the concrete raw materials towards the discharge end of the conveying cylinder 12. When the concrete raw materials are transported to the top of the movable cover 25, the operator starts the second motor 24. The second motor 24 will drive the movable cover 25. The movable cover 25 rotates back and forth on the top of the mixing drum 14. When the inlet 26 on the side wall of the movable cover 25 aligns with the outlet of the conveying drum 12, the concrete raw material passes through the movable cover 25 and enters the mixing drum 14. After entering the mixing drum 14, the concrete raw material accumulates between the first crushing roller 32 and the second crushing roller 33. Then, the operator starts the third motor 3, which drives the second movable shaft 31 to rotate. When the second movable shaft 31 rotates, it drives the first crushing roller 32 to rotate inside the mixing drum 14. The second crushing roller 33 rotates inside the mixing drum 14 under the drive of the first crushing roller 32 and the raw material. At this time, the raw material is pre-crushed under the combined action of the first crushing roller 32 and the second crushing roller 33. The operator starts the fourth motor 4, which drives the third movable shaft 41 to rotate. When the third movable shaft 41 rotates, it drives multiple mixing plates 42 to rotate. At this time, multiple mixing rods 43 on the side wall of the mixing plate 42 rotate inside the mixing drum 14. The mixing plate 42 and the mixing rods 43 will fully mix the concrete raw material inside the mixing drum 14.
