However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1 - Figure 3 As shown, the utility model provides a concrete mixing device, including a mixing barrel 1, a top cover 2 is provided on the top of the mixing barrel 1, a double mixing mechanism 3 is connected to the surface of the top cover 2, the double mixing mechanism 3 includes a motor 301, the output end of the motor 301 is connected to a first gear 302, a mixing rod 303 is inserted at the top center of the top cover 2, a second gear 304 is connected to the surface of the mixing rod 303 close to the first gear 302, a third gear 305 is connected to the top of the mixing rod 303, a fourth gear 306 is connected to one side of the third gear 305, and the fourth gear 307 is connected to the other side of the mixing rod 307. 6 is connected to one side of the sixth gear 307, the bottom of the sixth gear 307 is connected to the fifth gear 308, the bottom of the fifth gear 308 is connected to the stirring rod 310, and the surface of one side of the top cover 2 is connected to the stirring barrel 309. The motor 301 is electrically connected to the external power supply through the control switch. The output end of the motor 301 is fixedly connected to the first gear 302. The position and size of the first gear 302 match the position and size of the second gear 304. The second gear 304 is meshed with the first gear 302, and the sixth gear 307 is meshed with the fifth gear 308.

[0024] The effect achieved by the entire embodiment 1 is that when mixing concrete materials, the motor 301 can be started by controlling the switch, so that the output end of the motor 301 can drive the first gear 302 to rotate, and the first gear 302 can drive the second gear 304 to rotate. When the second gear 304 rotates, it also drives the mixing rod 303 to rotate inside the mixing barrel 1. When the mixing rod 303 rotates, it also drives the third gear 305 on the top to rotate and mesh with the fourth gear 306 to rotate, so that the fourth gear 306 can drive the sixth gear 307 to rotate, and then The fifth gear 308 is driven to rotate by the sixth gear 307, so that the fifth gear 308 can drive the stirring rod 310 to rotate in the mixing barrel 309, and the bottom end of the stirring rod 310 is connected to a group of support bars, which can support the stirring rod 310. At this time, the base material can be poured into the mixing barrel 309, so that the stirring rod 310 in the mixing barrel 309 can perform preliminary mixing of the materials. After the preliminary mixing, the materials will enter the mixing barrel 1 and be mixed for the second time through the stirring rod 310, thereby improving the mixing efficiency of the concrete, preparing the required concrete more quickly, and speeding up the construction progress.

[0025] Example 2, as Figure 1 and Figure 4 As shown, the outer surfaces of both sides of the mixing rod 303 are connected with a cleaning component 4, and the cleaning component 4 includes a support frame 401, a slot 402 is opened inside the support frame 401, a spring 403 is arranged inside the slot 402, one side of the spring 403 is connected to a push block 404, one side of the push block 404 is connected to a push rod 405, and one side of the push rod 405 is connected to a scraper 406, an elastic structure is formed between the push block 404 and the spring 403, and the outer surface of the scraper 406 is in contact with the inner wall of the mixing barrel 1.

[0026] The effect achieved by the entire embodiment 2 is that while the mixing rod 303 is mixing the materials, the spring 403 will also push the push block 404 through its own elastic force to drive the push rod 405 outward, and then push the scraper 406 to stick to the inner wall of the mixing barrel 1. While mixing the materials, it can also achieve automatic cleaning, thereby improving the overall practicality.

[0027] Working principle: By starting the motor 301, the gear is driven to transmit, thereby driving the mixing rod 303 and the stirring rod 310 to rotate simultaneously. After the material is poured into the mixing barrel 309, it is initially mixed and then enters the mixing barrel 1 for secondary mixing, thereby improving the mixing efficiency of the concrete material. The elastic force of the spring 403 pushes the scraper 406 to close to the inner wall of the mixing barrel 1 for cleaning, thereby improving the cleanliness of the inner wall of the mixing barrel 1.
