[0027] A stirring device 8, which is arranged on the upper surface of the support base 1, and is used to help the concrete in the protective device 6 to be mixed more fully;
[0028] Furthermore, according to the example Figure 2 As shown, the upper opening of the discharge chute 2 is set to be arc-shaped, the discharge chute 2 is inclined, and the inclination direction is toward the discharge port 3, so that the mixed concrete can flow out more conveniently through the slope of the discharge chute 2, avoiding excessive concrete remaining on the inner wall of the discharge chute 2.
[0029] Furthermore, according to the example Figure 4 As shown, the protection device 6 includes a mixing drum 61, a first baffle 62 is fixedly connected to the upper surface of the support seat 1 on one side of the mixing drum 61, and a first motor 63 is arranged on the inner wall of one side of the first baffle 62, a mixing rod 64 is fixedly connected to the output end of the first motor 63, and a limiting disk is arranged at the other end of the mixing rod 64, a spiral blade is arranged on the outer surface of the mixing rod 64, and a second baffle 65 is sleeved on one end of the mixing rod 64 provided with the limiting disk, and the second baffle 65 is fixedly connected to the upper surface of the support seat 1, so that the mixing rod 64 has the function of breaking up the concrete when rotating, so as to facilitate more uniform mixing of the concrete.
[0030] Furthermore, according to the example Figure 2 and Figure 4 As shown, an opening is provided at the bottom of the mixing drum 61 close to the discharge trough 2, and the size of the opening at the bottom of the mixing drum 61 is compatible with the size of the closing block 4 inserted into one end of the support seat 1, so that the closing block 4 can block the opening at the bottom of the mixing drum 61 to prevent the concrete from flowing out during the mixing process.
[0031] Furthermore, according to the example Figure 3 and Figure 5As shown, the stirring device 8 includes two groups of second motors 81, and the two groups of second motors 81 are respectively arranged at two opposite corners of the upper surface of the support base 1, and the output ends of the two groups of second motors 81 are fixedly connected with connecting rods 82. Openings are opened at both ends of the upper surface of the support base 1, and pinions 83 are fixedly connected at the opening positions of the upper surface of the support base 1 on the outer surface of the connecting rod 82, and two groups of pinions 83 are provided, and one side of the pinion 83 is meshed with a stirring gear 84, and the inner wall surfaces of the two groups of stirring gears 84 are fixedly connected with a circular ring, and the inner wall surfaces of the circular rings are fixedly connected with stirring blades 85, and multiple groups of stirring blades 85 are provided, and the multiple groups of stirring blades 85 are all in contact with the inner wall of the mixing drum 61, and the two groups of stirring gears 84 are respectively inserted at both ends of the mixing drum 61, so that when the stirring blades 85 rotate to stir the concrete inside the mixing drum 61, the concrete on the inner wall of the mixing drum 61 can be scraped for full mixing, and when the mixing drum 61 is cleaned, the residual concrete inside the mixing drum 61 can be scraped for cleaning.
[0032] Furthermore, according to the example Figure 5 As shown, both ends of the mixing blade 85 are set to be inclined, and the inclination direction is toward the middle position of the mixing blade 85, so that the concrete can move on the surface of the mixing blade 85 during the mixing of the concrete by the mixing blade 85, which improves the mixing efficiency of the concrete to a certain extent, and also allows the water for cleaning the inside of the mixing drum 61 to be gathered to the middle position of the inner wall of the mixing drum 61 through the slope, so that the water flow can be better discharged.
[0033] Working principle: When using the concrete mixer, move the support seat 1 to a suitable position, pour the concrete raw materials into the mixing drum 61 from the feeding port 7, and the first baffle 62 and the second baffle 65 seal the concrete raw materials in the mixing drum 61. When the raw materials are added, connect the power supply, and the first motor 63 drives the stirring rod 64 to rotate inside the mixing drum 61. At the same time, the second motor 81 drives the connecting rod 82 to rotate on the inner wall of the upper end of the support seat 1. The two groups of pinions 83 on the outer surface of the connecting rod 82 respectively drive the two groups of stirring gears 84 to rotate. While the two groups of stirring gears 84 rotate on both sides of the mixing drum 61, the multiple groups of stirring blades 85 between the two groups of stirring gears 84 are driven to rotate synchronously with the stirring gears 84. The stirring blades 85 drive the concrete inside the mixing drum 61 to stir and mix. When the stirring blades 85 drive the concrete to rotate to the upper end of the inner wall of the mixing drum 61 and fall off, the fallen concrete is broken up by the rotating stirring rod 64, and then mixed by the rotation of the stirring blades 85, and this is repeated.
[0034] After the concrete has been mixed by the protection device 6 and the stirring device 8, the power of the first motor 63 and the second motor 81 is reduced. At this time, the concrete inside the mixing drum 61 flows to the middle position of the mixing drum 61 through the slopes at both ends of the surface of the stirring blade 85, and the closing block 4 is pulled to open the opening at the bottom of the mixing drum 61. The concrete flows from the opening at the bottom of the mixing drum 61 to the inner wall of the discharge trough 2, and then is discharged to the outside of the mixer through the discharge port 3. When the concrete inside the mixing drum 61 is completely discharged, the closing block 4 is released. At this time, the return springs 5 at both ends of the closing block 4 reset the closing block 4 through their own elasticity, and water is poured into the mixing drum 61 from the feed port 7. The water is scraped by the rotation of the stirring blade 85, so that the small amount of concrete remaining on the inner wall of the mixing drum 61 is completely cleaned, and the power is turned off, and the closing block 4 is opened to completely discharge the water inside the mixing drum 61 through the discharge port 3. At this time, the device is cleaned.
