[0001] The utility model relates to the technical field of concrete, in particular to an efficient mixing device for commercial concrete. Background Technique

[0002] Concrete mixing is an operation method of mixing materials such as cement, lime, and water evenly. Concrete mixing is divided into two types: manual mixing and mechanical mixing. Concrete mixing plants are widely used in construction projects such as industry, agriculture, transportation, national defense, water conservancy, and municipal administration in China, and the demand is increasing continuously.

[0003] In the patent document with the authorized publication number of CN214561939U, a field of concrete mixing is disclosed. In the present utility model, it includes a box body and a feeding pipe. A box door is arranged on the front surface of the box body. A motor box is fixedly installed on the top of the box body. A second motor is fixedly installed inside the motor box. A second feeding port is opened on one side of the top of the box body close to the motor box. A discharge port is opened at the bottom of the box body. A one-way control valve is arranged at the bottom of the discharge port. This device is more convenient during feeding, eliminating the need for manual feeding, being simple and convenient, saving labor costs, and improving work efficiency. By the simultaneous rotation of the mixing blades and the mixing rods, a shearing force is formed with the round holes on the mixing rods, making the concrete mixing sufficient, improving the quality and safety of the project. When the device finishes working, the staff can open the box door to clean its interior.

[0004] When the above device is implemented, when the mixing drum mixes concrete, the inner wall of the mixing drum will continuously adhere to the concrete, thereby reducing the mixing space inside the mixing drum and thus reducing the efficiency of concrete mixing. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an efficient mixing device for commercial concrete, which solves the problem that when the above device is implemented, when the mixing drum mixes concrete, the inner wall of the mixing drum will continuously adhere to the concrete, thereby reducing the mixing space inside the mixing drum and thus reducing the efficiency of concrete mixing.

A plurality of pneumatic hammers are installed at the upper and lower ends of the fixed ring respectively. A plurality of impact blocks are fixedly installed on the outer wall of the mixing drum at the telescopic ends of the plurality of pneumatic hammers.

[0007] By adopting the above technical solution, when the rotating block rotates, it can drive the outer stirring blades to rotate. When the outer stirring blades rotate, they can mix the concrete. After the concrete is mixed and then discharged, when the outer stirring blades rotate, they will continue to strike the vibrating blades. The vibrating blades can rotate with the rotating rod to unload the force. When the concrete is stirred, the stirring mechanism generally does not rotate too fast, so the striking force will not be too large. Thus, without damaging the outer stirring blades, the outer stirring blades can vibrate. And the pneumatic hammer can strike the impact block to make the inner wall of the mixing cylinder vibrate, so that the concrete on the inner wall of the outer stirring blades and the mixing cylinder can fall, effectively preventing the accumulation of concrete on the inner wall of the mixing cylinder and ensuring that the internal space of the mixing cylinder plays a better role in mixing the concrete.

[0010] Optionally, a first bevel gear is installed at the upper end of the rotating block, and a second bevel gear is fixedly connected to the upper end of the stirring rod.

[0011] By adopting the above technical solution, the rotating block can fix the first bevel gear, and the stirring rod can fix the second bevel gear.

[0012] Optionally, a motor is installed at the upper end of the mixing cylinder, and an output shaft of the motor is fixedly connected with a third bevel gear, and the third bevel gear meshes with the first bevel gear and the second bevel gear.

[0013] By adopting the above technical solution, the motor can drive the third bevel gear to rotate, and the third bevel gear can drive the first bevel gear and the second bevel gear to rotate.

[0014] Optionally, a feed hole is formed in the upper side of the mixing cylinder, and a feed cylinder is installed at the upper end of the mixing cylinder above the feed hole.

[0015] By adopting the above technical solution, the arrangement of the feed hole and the feed cylinder can play a role in adding concrete raw materials.

[0016] Optionally, three supporting feet are fixedly connected to the lower end of the fixed ring, and the three supporting feet are evenly arranged in a ring.

[0017] By adopting the above technical solution, the fixed ring can fix the supporting feet, and the supporting feet can support the mixing cylinder.

[0018] Optionally, a blanking pipe is fixedly installed at the lower end of the mixing cylinder, and a valve is installed inside the blanking pipe.

[0019] By adopting the above technical solution, the blanking pipe can play a role in discharging concrete, and the valve can play a role in closing and opening the blanking pipe.

[0020] Optionally, the vertical cross-section of the rotating block and the stirring rod is cross-shaped.

[0021] By adopting the above technical solution, since the vertical cross-section of the rotating block and the stirring rod is cross-shaped, it can effectively make the rotating block and the stirring rod play a role in rotational support during installation.

The vibration blades can rotate with the rotating rod to unload the force. When the concrete is stirred, the rotation speed of the stirring mechanism is generally not too fast, so the striking force will not be too large. Thus, without damaging the outer stirring blades, the outer stirring blades can be vibrated. And the pneumatic hammer can strike the impact block to make the inner wall of the mixing cylinder vibrate, so that the concrete on the inner wall of the outer stirring blades and the mixing cylinder can fall, effectively preventing the accumulation of concrete on the inner wall of the mixing cylinder and ensuring that the internal space of the mixing cylinder plays a better role in mixing the concrete.

Specific embodiments

[0031] Please refer to Figures 1-4 , the present utility model provides a technical solution: an efficient mixing device for commercial concrete, including a mixing cylinder 1, a rotating block 2 is rotatably installed on the inner top wall of the mixing cylinder 1, two groups of outer mixing blades 3 are installed on the outer wall below the rotating block 2, a rotating rod 4 is rotatably installed on the inner top wall of the mixing cylinder 1, a plurality of vibrating blades 5 are fixedly connected to the outer wall of the rotating rod 4, and the positions of the plurality of vibrating blades 5 correspond to those of the outer mixing blades 3. A fixing ring 8 is fixedly installed on the outer wall of the mixing cylinder 1, and a plurality of pneumatic hammers 10 are installed on the upper end and the lower end of the fixing ring 8 respectively. A plurality of impact blocks 9 are fixedly installed on the outer wall of the mixing cylinder 1 at the telescopic ends of the plurality of pneumatic hammers 10. A feed hole is opened on the upper side of the mixing cylinder 1, and a feed cylinder 15 is installed at the upper end of the mixing cylinder 1 above the feed hole.

[0032] In the technical solution of the present utility model, when the rotating block 2 rotates, it can drive the outer mixing blades 3 to rotate, and when the outer mixing blades 3 rotate, they can mix the concrete. After the concrete is mixed and then discharged, when the outer mixing blades 3 rotate, they will continue to strike the vibrating blades 5, and the vibrating blades 5 can rotate with the rotating rod 4 to unload the force. When the concrete is being mixed, the mixing mechanism generally does not rotate too fast, so the striking force will not be too large. Thus, without damaging the outer mixing blades 3, the outer mixing blades 3 can vibrate. And the pneumatic hammers 10 can strike the impact blocks 9 to make the inner wall of the mixing cylinder 1 vibrate, so that the concrete on the inner wall of the outer mixing blades 3 and the mixing cylinder 1 can fall, effectively preventing the accumulation of concrete on the inner wall of the mixing cylinder 1 and ensuring that the internal space of the mixing cylinder 1 plays a better role in mixing the concrete.

[0033] In addition, through the arrangement of the feed hole and the feed cylinder 15, the concrete raw materials can be added.

[0034] In the technical solution of the present utility model, such as Figure 1 , Figure 3 and Figure 4As shown in the figure, a stirring rod 6 is rotatably installed inside the rotating block 2. A plurality of inner stirring blades 7 are installed on the outer wall of the stirring rod 6 located inside the mixing cylinder 1. The rotating rod 4 can play a role in rotatably supporting the stirring rod 6, and the stirring rod 6 can drive the inner stirring blades 7 to rotate, thereby playing a role in mixing the concrete. A first bevel gear 11 is installed at the upper end of the rotating block 2, and a second bevel gear 12 is fixedly connected to the upper end of the stirring rod 6. The rotating block 2 can play a role in fixing the first bevel gear 11, and the stirring rod 6 can play a role in fixing the second bevel gear 12. A motor 13 is installed at the upper end of the mixing cylinder 1, and an output shaft of the motor 13 is fixedly connected to a third bevel gear 14. The third bevel gear 14 meshes with the first bevel gear 11 and the second bevel gear 12. The motor 13 can drive the third bevel gear 14 to rotate, and the third bevel gear 14 can drive the first bevel gear 11 and the second bevel gear 12 to rotate.

[0035] In the technical solution of the present utility model, as Figure 5 shown, the vertical cross-sections of the rotating block 2 and the stirring rod 6 are cross-shaped. By setting the vertical cross-sections of the rotating block 2 and the stirring rod 6 to be cross-shaped, it can effectively play a role in rotatably supporting the rotating block 2 and the stirring rod 6 during installation.

[0036] In the technical solution of the present utility model, as Figure 1 shown, three support feet 16 are fixedly connected to the lower end of the fixed ring 8. The three support feet 16 are evenly arranged in a ring shape. The fixed ring 8 can play a role in fixing the support feet 16, and the support feet 16 can play a role in supporting the mixing cylinder 1.

[0037] In the technical solution of the present utility model, as Figure 1 shown, a discharge pipe 17 is fixedly installed at the lower end of the mixing cylinder 1. A valve 18 is installed inside the discharge pipe 17. The discharge pipe 17 can play a role in discharging the concrete, and the valve 18 can play a role in closing and opening the discharge pipe 17.

[0038] During use, first, check whether all components are in good condition, especially key components such as the motor 13, pneumatic hammer 10, and stirring rod 6. Open the valve 18 on the material discharge pipe 17 to ensure that there is no residual concrete inside the mixing drum 1. Then close the valve 18 and prepare for feeding. Pour the concrete raw materials into the mixing drum 1 through the feeding cylinder 15 and the feeding hole. According to the concrete mix ratio, ensure that the proportions of various raw materials are correct. Start the motor 13, and the motor 13 drives the third bevel gear 14 to rotate. The third bevel gear 14 meshes with the first bevel gear 11 and the second bevel gear 12 simultaneously, driving the rotating block 2 and the stirring rod 6 to rotate at the same time. The rotating block 2 and the stirring rod 6 rotate in opposite directions, and the outer stirring blades 3 and the inner stirring blades 7 that rotate in opposite directions start to stir the concrete in the mixing drum 1 driven by the rotating block 2 and the stirring rod 6. At the same time, the pneumatic hammer 10 on the fixed ring 8 starts to work, and its telescopic end continuously impacts the impact block 9 on the mixing drum 1. The vibration generated helps prevent the concrete from adhering to the inner wall of the mixing drum 1. The rapid rotation of the outer stirring blades 3 and the inner stirring blades 7, together with the vibration generated by the pneumatic hammer 10, act together to make the concrete in the mixing drum 1 be mixed evenly and efficiently. The vibration blades 5 and the force field generated by the vibration help break the agglomeration in the concrete and make it more uniform. The vibration effect of the pneumatic hammer 10 not only helps improve the stirring efficiency and effectively reduces the generation of air bubbles inside the concrete, but more importantly, it effectively prevents the concrete from adhering to the inner wall of the mixing drum 1. The vibration causes the concrete to continuously fall off from the inner wall, maintaining the effective mixing space inside the mixing drum 1. When the concrete is mixed evenly, turn off the motor 13 and the pneumatic hammer 10, open the valve 18 on the material discharge pipe 17, and discharge the concrete from the mixing drum 1. Through this working process, this commercial concrete high-efficiency stirring device can mix the concrete efficiently and evenly, and effectively prevent the concrete from adhering to the inner wall of the mixing drum 1, thereby improving the efficiency and quality of concrete mixing.
