Moreover, in actual use, vertical concrete mixers often have the problem of material lumps at the discharge port, which causes the discharge port to be blocked. Because in the process of concrete mixing, cement solidifies due to insufficient mixing and dispersion, which makes the discharge port easy to be blocked, and the mixer cannot discharge materials.

[0030] A first rotating shaft 9 is connected to the output end of the first motor 8, and the first rotating shaft 9 is connected to a sliding assembly through a bearing. The sliding assembly is slidably connected to a sliding hole 10 opened on the upper cover 5. The sliding assembly includes a sliding sleeve 23, and the sliding sleeve 23 is slidably connected to the sliding hole 10. A sliding rail 24 is connected to the outer wall of the sliding sleeve 23, and the sliding rail 24 is slidably connected to a sliding groove 25 opened on the inner wall of the sliding hole 10. The first rotating shaft 9 is connected to the inside of the sliding sleeve 23 through a bearing.

[0031] A truncated cone-shaped protective cover 32 is connected to the bottom surface of the upper cover 5. The protective cover 32 is sleeved on the first rotating shaft 9. A sleeve 17 is connected to the bottom of the protective cover 32. The first rotating shaft 9 slides up and down in the sleeve 17. The protective cover 32 prevents splashing materials from damaging the sliding sleeve 23.

[0032] The bottom of the first rotating shaft 9 is placed in the mixing tank 2 and is connected to the crushing body 11 through a buffer assembly.

At the same time, the second motor 16 drives the mixing tank 2 to rotate 180° repeatedly to prevent the material from being blocked at the discharge port 3. When the mixing is completed, the second motor 16 drives the mixing tank 2 to reset so that the discharge port 3 faces downward, and then a trolley is set below the discharge port 3 to open the solenoid valve 4 to discharge the mixed concrete. At the same time, the telescopic end of the hydraulic cylinder 19 rises and falls continuously, thereby driving the crushing body 11 to move up and down continuously in the discharge port 3 to assist in discharging and prevent the concrete from blocking the discharge port 3.
