[0025] The mixing tank 8 is arranged in the U-shaped frame 3. The bottom of the mixing tank 8 is rotatably connected to the U-shaped frame 3 through the fixed shaft 4. The crushed stone is put into the mixing tank 8 through the upper port of the mixing tank 8, and the concrete mixing element mixes the cement stone.

[0026] The first bracket 1 and the second bracket 5 are rotatably connected to the left and right sides of the U-shaped frame 3. The upper end of the first bracket 1 is provided with a first driving member for controlling the flipping of the U-shaped frame 3, and the upper end of the second bracket 5 is provided with a second driving member for controlling the rotation of the mixing tank 8.

[0027] During the mixing process, the second drive member controls the rotation of the mixing tank 8 in the opposite direction of the mixing direction of the concrete mixing element, thereby accelerating the mixing of the cement and stone materials in the mixing tank 8. During unloading, the first drive member controls the turning of the mixing tank 8 via the U-shaped frame 3. During the turning, the mixing tank 8 coordinates its rotation with the rotation of the concrete mixing element to quickly pour out the stone materials, making the unloading of cement and stone materials convenient.

[0028] About concrete mixing parts:

[0029] The concrete mixing element includes a fixing frame 15 and a third motor 16. The fixing frame 15 is fixedly connected to the upper end of the mixing tank 8. The mounting end of the third motor 16 is fixedly connected to the upper end of the fixing frame 15. The output end of the third motor 16 is fixedly connected to the mixing shaft 17 provided in the mixing tank 8. A plurality of mixing blades 18 are fixedly connected to the outside of the shaft of the mixing shaft 17.

[0030] The rotation of the stirring shaft 17 is controlled by the third motor 16. The stone is put into the stirring tank 8 through the upper port of the stirring tank 8. The third motor 16 controls the rotation of the stirring shaft 17. The stirring shaft 17 stirs the stone through the stirring blades 18 during rotation to mix the stone.

[0031] For the specific structures of the first driving member and the second driving member, please refer to the following description.

[0032] The first driving member includes a first rotating shaft 7, which is fixedly connected to one side of the U-shaped frame 3. The end of the first rotating shaft 7 away from the U-shaped frame 3 is rotatably connected to the first bracket 1. A first motor 6 is installed on the upper end of the first bracket 1, and the output end of the first motor 6 is fixedly connected to the first rotating shaft 7.

[0033] During unloading, the first motor 6 drives the first rotating shaft 7 to rotate. Since the U-shaped frame 3 is fixed to the first rotating shaft 7, when the first rotating shaft 7 rotates, the U-shaped frame 3 will turn over, and the mixing tank 8 inside the U-shaped frame 3 will also turn over.

[0034] The second driving member includes a second rotating shaft 11, which is arranged through the other side of the U-shaped frame 3. The second rotating shaft 11 is fixedly connected to a gear 10 at one end close to the stirring tank 8. The gear 10 is engaged with a gear ring 9 sleeved on the outside of the stirring tank 8. The gear ring 9 is fixedly connected to the stirring tank 8. The second rotating shaft 11 is rotatably connected to the second bracket 5 at one end away from the stirring tank 8. A second motor 12 for controlling the rotation of the second rotating shaft 11 is installed on the upper end of the second bracket 5.

[0035] The second motor 12 drives the second rotating shaft 11 to rotate, and the second rotating shaft 11 drives the gear 10 to rotate, the gear 10 meshes with the gear ring 9, and drives the gear ring 9 to rotate, because the stirring tank 8 is fixed with the gear ring 9, so the stirring tank 8 also rotates. The second rotating shaft 11 penetrates the U-shaped frame 3, and when the U-shaped frame 3 is turned over, the rotation of the second rotating shaft 11 is not affected.

[0036] Regarding the fixed shaft 4:

[0037] The lower end of the fixed shaft 4 is fixedly connected with the U-shaped frame 3, the upper end of the fixed shaft 4 penetrates the bottom of the stirring tank 8, and the fixed shaft 4 is rotatably connected with the stirring tank 8. A bearing member for supporting the stirring tank 8 to rotate around the fixed shaft 4 is arranged at the connection between the fixed shaft 4 and the stirring tank 8. Since the stirring tank 8 needs to bear the stones, when the stirring device is assembled, it is necessary to check whether the connection between the fixed shaft 4 and the stirring tank 8 has good structural strength.

[0038] In order to facilitate the staff to clean the inner side wall of the stirring tank 8, in the preferred scheme, a connecting plate 14 is arranged in the stirring tank 8, the connecting plate 14 is arranged below the stirring shaft 17, the connecting plate 14 is fixedly connected to the upper end of the fixed shaft 4, and the left and right ends of the connecting plate 14 are fixedly connected with the scraping plates 13, and the scraping plates 13 are in contact with the inner side wall of the stirring tank 8.

[0039] When the stirring tank 8 rotates, the connecting plate 14 fixed with the fixed shaft 4 is in a state of not moving, the scraping plates 13 are fixed at the two ends of the connecting plate 14 and are in contact with the inner side wall of the stirring tank 8, the stirring tank 8 rubs against the scraping plates 13 through its rotation, and the scraping plates 13 scrape off the debris attached to the inner side wall of the stirring tank 8.

[0040] In order to improve the structural strength of the fixed support, in the preferred scheme, a reinforcing rib is arranged at the connection between the fixed plate 2 and the first support 1, and the reinforcing rib is a triangular rib plate fixedly connected at the included angle between the first support 1 and the fixed plate 2.

[0041] The working principle of the present application is as follows:

[0042] The stirring tank 8 is arranged in the U-shaped frame 3, the bottom of the stirring tank 8 is rotatably connected with the U-shaped frame 3 through the fixed shaft 4, the stones are poured into the stirring tank 8 through the upper port of the stirring tank 8, and the cement stones are stirred by the concrete stirring member. During the mixing process, the second driving member controls the stirring tank 8 to rotate, the rotating direction of the stirring tank 8 is opposite to the stirring direction of the concrete stirring member, so as to accelerate the mixing of the cement stones in the stirring tank 8. When discharging, the first driving member controls the stirring tank 8 to turn over through the U-shaped frame 3, and the stirring tank 8 rotates in cooperation with the rotation of the concrete stirring member, so that the stones in the stirring tank 8 are quickly poured out, and the cement stones are conveniently discharged.
