[0002] Lightweight aggregate concrete refers to concrete using lightweight aggregate, and its apparent density is not more than 1950kg / m3. The so-called lightweight aggregate is an aggregate used to reduce the mass of concrete and improve the thermal effect, and its apparent density is lower than that of ordinary aggregate. Artificial lightweight aggregate is also called ceramsite. When mixing lightweight aggregate concrete, the raw materials of lightweight aggregate concrete are put into a mixing tank, and then the motor is used to drive the stirring rod to rotate, so as to mix the lightweight aggregate concrete.

[0003] In actual use, the position of the stirring rod is fixed, so the stirring rod can only stir the lightweight aggregate concrete at the same position of the mixing tank, and cannot stir the lightweight aggregate concrete at different positions, thereby reducing the stirring effect and increasing the limitations of the device, which is not conducive to actual use.

[0011] As a preferred embodiment, a feeding port is provided at the bottom of the stirring tank, and a feeding trough is fixedly connected to one end of the bottom of the stirring tank which is located away from the feeding port and away from the outside.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are: when mixing concrete, the motor drives the rotating shaft to rotate, and through the cooperation of the flat key and the keyway, the rotating shaft drives the stirring rod to rotate, and the roller at one end of the stirring rod rotates in the circular track.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] Example 1

[0021] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: it includes a stirring tank 15, the top of the stirring tank 15 is fixedly connected to a top cover 18, a rotating shaft 8 is rotatably connected between the bottom of the inner wall of the stirring tank 15 and the bottom of the top cover 18, a shaft sleeve 11 is slidably connected to the outer side of the rotating shaft 8, a stirring rod 5 is equidistantly fixedly connected to the outer side of the shaft sleeve 11, a connecting component is arranged between the shaft sleeve 11 and the rotating shaft 8, an annular track 12 is slidably connected to the inside of the stirring tank 15, a motor 13 is fixedly installed at the bottom of the stirring tank 15, an output shaft of the motor 13 is fixedly connected to one end of the rotating shaft 8, electric telescopic rods 6 are fixedly installed at both ends of the top of the top cover 18, and one end of the movable rod of the electric telescopic rod 6 is fixedly connected to the top of the annular track 12.

[0022] Through the above embodiment, when the lightweight aggregate concrete is stirred, the rotating shaft 8 is driven by the motor 13. Since a connecting assembly is provided between the rotating shaft 8 and the shaft sleeve 11, the shaft sleeve 11 is driven to rotate, and the stirring rod 5 is driven to rotate at the same time, thereby stirring the lightweight aggregate concrete. Then, the electric telescopic rod 6 is used to drive the annular track 12 to move up and down, thereby driving the stirring rod 5 to move up and down, and then the lightweight aggregate concrete at different heights inside the mixing tank 15 can be stirred, thereby enhancing the stirring effect and avoiding the traditional stirring by a stirring shaft, making it more conducive to practical use and enhancing the practicality of the device.

[0023] Example 2

[0024] like Figure 1-Figure 4 As shown, the connection assembly includes a flat key 16, which is fixedly connected to the inner side of the shaft sleeve 11. A key slot 17 is provided on one side of the rotating shaft 8, and the outer side of the flat key 16 is slidably connected to the inner wall of the key slot 17. One end of the stirring rod 5 is rotatably connected to the roller 3, and the inner wall of the annular track 12 is provided with an annular groove, and the outer side of the roller 3 abuts against the inner wall of the annular groove on the inner side of the annular track 12. Slide blocks 10 are fixedly connected to both ends of the annular track 12, and two slide rails 9 are fixedly connected to the inner wall of the stirring tank 15, and the slide blocks 10 are slidably connected to the slide rails 9. Since a key slot 17 is provided on one side of the rotating shaft 8 and the flat key 16 is fixedly connected to the inner side of the sleeve 11, the rotating shaft 8 rotates to drive the sleeve 11 to rotate through the cooperation of the key slot 17 and the flat key 16, and then drives the stirring rod 5 to rotate. Since one end of the stirring rod 5 is rotatably connected to the roller 3 and abuts against the inner wall of the annular groove on the inner side of the annular track 12, the roller 3 rolls in the annular groove of the annular track 12, thereby limiting the stirring rod 5. The electric telescopic rod 6 is used to drive the annular track 12 to slide on the inner wall of the slide rail 9, thereby driving the stirring rod 5 to slide up and down, and then the stirring rod 5 is rotated up and down in the stirring tank 15.

[0025] Among them, the bottom of the mixing tank 15 is fixedly connected with a bracket 2 at equal intervals, and the bottom ends of the brackets 2 are fixedly connected with a base 1. The top of the top cover 18 is fixedly connected with a feed port 7. The bottom of the mixing tank 15 is fixedly connected with a discharge port 4, and a valve is provided on one side of the discharge port 4. The bottom of the mixing tank 15 and below the discharge port 4 is fixedly connected with a discharge trough 14. The base 1 fixedly connected by the bracket 2 increases the force-bearing area of ​​the bracket 2, thereby increasing the stability of the mixing tank 15. The feed port 7 is set to a funnel shape to avoid leakage during feeding and prevent waste. The material is discharged through the discharge port 4, and the concrete discharged from the discharge port 4 can be concentrated through the discharge trough 14 to guide it for easy collection.

[0026] Working principle: when mixing concrete, the motor 13 drives the rotating shaft 8 to rotate, and the flat key 16 fixedly connected to the inner wall of the sleeve 11 is slidably connected with the key groove 17 opened on one side of the rotating shaft 8, thereby driving the sleeve 11 to rotate. Because one end of the stirring rod 5 is fixedly connected to the outer side of the sleeve 11, the stirring rod 5 is driven to rotate, and the sleeve 11 can slide up and down, and the outer side of the roller 3 rotatably connected by one end of the stirring rod 5 abuts against the inner wall of the annular groove in the annular track 12, and the roller 3 rolls in the annular groove. Slide blocks 10 are fixedly connected at both ends of the annular track 12, and the slide block 10 is slidably connected to the slide rail 9 fixedly connected to the inner wall of the mixing tank 15, so that the annular track 12 can slide up and down, and one end of the movable rod of the electric telescopic rod 6 is fixedly connected to the top of the annular track 12. When the electric telescopic rod 6 drives the annular track 12 to move up and down, the annular track 12 slides up and down in the mixing tank 15, thereby driving the stirring rod 5 to slide up and down. At this time, the stirring rod 5 rotates up and down in the mixing tank 15, so that concrete at different heights in the mixing tank 15 is evenly stirred, thereby enhancing the stirring effect.
