Description

Technical Field

[0001] The present application relates to the technical field of concrete mixing, and specifically relates to an efficient concrete mixing device. Background Art

[0002] During the process of engineering construction, it is necessary to mix and stir concrete. Concrete mixing enables various materials to be evenly mixed, and cement can fully contact materials such as stones and sand to form a more solid concrete body. Moreover, the evenly mixed concrete slurry can fully lock in moisture, reduce problems such as cracking and leakage, thereby extending the service life of concrete.

[0003] Patent No. CN 221021731 U discloses an efficient concrete mixing device. By means of a mixing drum, a connecting frame, a mounting plate, a motor, a semi-gear, a rack, a slider, a chute, a spring, and a controller, driven by the motor, the semi-gear rotates continuously, driving the slider and the filter tank to continuously move up and down reciprocally, thereby tumbling and screening the internal raw materials, preventing raw materials with larger particle sizes from entering the inside of the mixing drum, thus improving the mixing quality and speed, and prolonging the service life of the impeller inside the mixing drum. At the same time, the quality of the mixed cement can also be effectively improved.

[0004] However, in use, the following problems remain unsolved:

[0005] Although the slider and the filter tank are used to tumble and screen the internal raw materials by moving up and down, during the process of the raw materials entering the mixing drum for mixing, the concrete will settle at the bottom of the drum due to the action of gravity, with a relatively small contact area with the mixing structure, thus affecting the mixing efficiency. Utility Model Content

[0006] The purpose of the present application is to provide an efficient concrete mixing device, which solves the problem that during the process of the raw materials entering the mixing drum for mixing, the concrete will settle at the bottom of the drum due to the action of gravity, with a relatively small contact area with the mixing structure, thus affecting the mixing efficiency as proposed in the background art.

[0007] To achieve the above purpose, the present application provides the following technical solution: An efficient concrete mixing device includes a mixing drum, a fixed drum, a filter screen, and a fixing plate. Electric push rods are fixedly connected to both sides of the top end of the mixing drum. The bottom telescopic end of the electric push rod penetrates through the top surface of the mixing drum and is fixedly connected to the top surface of the fixed drum. A number of lifting plates are evenly fixedly connected to the inner side wall of the fixed drum. A rotating shaft is rotatably connected to the center of the inner bottom of the mixing drum. A number of mixing rods are fixedly connected to the surface of the rotating shaft. A slot is opened at one end of the mixing rod facing the fixed drum. A fixing plate is movably inserted into the slot, and a cleaning brush is fixedly connected to the surface of the fixing plate facing the inner wall of the fixed drum.

[0008] In this technical solution, after the electric push rod is started, it extends and retracts, driving the fixed cylinder to lift and lower. During the lifting and lowering process, the lifting plate will continuously lift the concrete at the bottom, causing it to turn and circulate, increasing the contact area between the concrete at different positions and the stirring rod, and improving the stirring efficiency; after opening the top cover, the fixing plate is inserted into the slot and fixed by the fixing bolt. At this time, the cleaning brush will contact the inner wall of the fixed cylinder, and during the rotation of the rotating shaft, the residual concrete on the lifting plate and the fixed cylinder will be swept off, avoiding the residual concrete and improving the collection efficiency of the concrete.

[0009] Preferably, the top of the mixing cylinder is movably connected with a top cover, and the center of the top of the top cover is fixedly connected with a feeding groove, and the feeding groove is communicated with the inside of the mixing cylinder.

[0010] Preferably, two horizontal crushing rollers are rotatably connected between the front and rear inner side walls of the feeding groove. One end of the crushing roller is fixedly connected with a first servo motor on the outer side wall of the feeding groove at the horizontal position, and the outer end of the transmission shaft of the first servo motor is fixedly connected with one end of the crushing roller.

[0011] Preferably, a filter screen is movably inserted into the outer side wall of the feeding groove below the crushing roller.

[0012] Preferably, a second servo motor is fixedly connected to the center of the bottom of the mixing cylinder, and the outer end of the transmission shaft of the second servo motor is fixedly connected to the bottom end of the rotating shaft.

[0013] Preferably, a fixing bolt is threadedly connected to the surface of the stirring rod outside the slot, and one end of the fixing bolt passes through the surface of the stirring rod and is threadedly connected to the surface of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] 1. Through the electric push rod, the fixed cylinder and the lifting plate, the present application can lift the concrete. After the electric push rod is started, it extends and retracts, driving the fixed cylinder to lift and lower. During the lifting and lowering process, the lifting plate will continuously lift the concrete at the bottom, causing it to turn and circulate, increasing the contact area between the concrete at different positions and the stirring rod, and improving the stirring efficiency.

[0016] 2. Through the slot, the fixing plate and the cleaning brush, the present application can clean the lifting plate and the fixed cylinder.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved objectives, and functions of the present utility model easy to understand, the following will further elaborate with reference to specific implementation manners.

[0022] An efficient concrete mixing device, refer to Figures 1 to 2 , including a mixing drum 1, a fixed cylinder 8, a filter screen 6, and a fixing plate 15. Electric push rods 7 are fixedly connected to both sides of the top end of the mixing drum 1. The bottom telescopic end of the electric push rod 7 penetrates the top surface of the mixing drum 1 and is fixedly connected to the top surface of the fixed cylinder 8. A plurality of lifting plates 9 are evenly and fixedly connected to the inner side wall of the fixed cylinder 8. When the fixed cylinder 8 moves up and down, the lifting plates 9 will continuously lift the concrete at the bottom during the lifting and lowering process, causing it to turn and circulate, increasing the contact area between the concrete at different positions and the stirring rod 12, and improving the mixing efficiency.

[0023] The central part of the inner bottom of the mixing drum 1 is rotatably connected with a rotating shaft 11. A plurality of stirring rods 12 are fixedly connected to the surface of the rotating shaft 11. A slot 13 is formed at one end of the stirring rod 12 facing the fixed cylinder 8. A fixing plate 15 is movably inserted into the inner side of the slot 13. And a cleaning brush 16 is fixedly connected to the surface of the fixing plate 15 facing the inner wall of the fixed cylinder 8. The cleaning brush 16 will contact the inner wall of the fixed cylinder 8. During the rotation of the rotating shaft 11, the concrete remaining on the lifting plates 9 and the fixed cylinder 8 will be swept down, avoiding the residue of concrete.

[0024] Specifically, as Figure 2 shown, the top end of the mixing drum 1 is movably connected with a top cover 2. The central part of the top end of the top cover 2 is fixedly connected with a feeding trough 3, and the feeding trough 3 is communicated with the inner side of the mixing drum 1. The top cover 2 can be disassembled, which is convenient for cleaning the inner side of the mixing drum 1 and disassembling and assembling the fixing plate 15.

[0025] It should be noted that, as Figure 1 and Figure 2 shown, two horizontal crushing rollers 4 are rotatably connected between the front and rear inner side walls of the feeding trough 3. One end of the crushing roller 4 is fixedly connected to the outer side wall of the feeding trough 3 at the horizontal position. The outer end of the transmission shaft of the first servo motor 5 is fixedly connected to one end of the crushing roller 4. During the rotation of the crushing roller 4, larger raw material particles will be crushed, so that all the stirred raw materials can maintain a smaller particle state, facilitating more uniform stirring and mixing.

[0026] It should be noted that, as Figure 1 shown, a filter screen 6 is movably inserted into the outer side wall of the feeding trough 3 below the crushing roller 4. The filter screen 6 can intercept larger particles, and the filter screen 6 is located below the crushing roller 4, and the distance between the two is extremely small. The intercepted large particles can contact the crushing roller 4 and can only pass through the filter screen 6 after being crushed. The filter screen 6 is designed to be pulled out for cleaning.

[0027] It should be noted that, as Figure 2 shown, a second servo motor 10 is fixedly connected to the center of the bottom of the mixing cylinder 1. The outer end of the transmission shaft of the second servo motor 10 is fixedly connected to the bottom end of the rotating shaft 11. After the second servo motor 10 is started, it drives the rotating shaft 11 to rotate, so that the mixing rod 12 starts to mix the raw materials.

[0028] It should be noted that, as Figure 2 shown, a fixing bolt 14 is threadedly connected to the surface of the mixing rod 12 outside the slot 13. One end of the fixing bolt 14 passes through the surface of the mixing rod 12 and is threadedly connected to the surface of the fixing plate 15. Slots 13 are provided on each side of the mixing rod 12. Therefore, the fixing plate 15 can be randomly installed on any side of the mixing rod 12, thus improving the convenience. The fixing bolt 14 does not need to be screwed in on the side where the fixing plate 15 is not installed.

[0029] During actual use, concrete raw materials are added to the feeding trough 3. The first servo motor 5 starts to drive the crushing roller 4 to rotate, crushing the larger particles in the raw materials. The crushed raw materials pass through the filter screen 6 and enter the mixing drum 1. At this time, the second servo motor 10 starts to drive the rotating shaft 11 and the mixing rod 12 to rotate, and begins to mix the raw materials. Through the electric push rod 7, the fixed cylinder 8 and the lifting plate 9, the concrete can be lifted. After the electric push rod 7 starts, it extends and retracts, driving the fixed cylinder 8 to move up and down. During the lifting and lowering process, the lifting plate 9 will continuously lift the concrete at the bottom, making it turn over and circulate, increasing the contact area between the concrete at different positions and the mixing rod 12, and improving the mixing efficiency. After the mixing is completed, the concrete leaves the mixing drum 1 along the discharge port 17. At this time, through the slot 13, the fixing plate 15 and the cleaning brush 16, the lifting plate 9 and the fixed cylinder 8 can be cleaned. After opening the top cover 2, the fixing plate 15 is inserted into the slot 13 and fixed by the fixing bolt 14. At this time, the cleaning brush 16 will contact the inner wall of the fixed cylinder 8, and during the rotation of the rotating shaft 11, the residual concrete on the lifting plate 9 and the fixed cylinder 8 will be swept off, avoiding the residue of concrete and improving the collection efficiency of concrete. After the cleaning is completed, the fixing plate 15 can be taken out for cleaning to avoid the residue of concrete.
