However, the blades of the concrete mixer are fixed by welding, which means that when the blades are replaced, the entire shaft needs to be replaced, which increases the cost loss. Therefore, in order to solve the problem that the blades of the existing concrete mixer are fixed by welding, which means that when the blades are replaced, the entire shaft needs to be replaced, which increases the cost loss, the present solution provides a mounting groove 2 to facilitate the disassembly of the mounting ring 1 and the shaft, thereby making it more convenient for subsequent disassembly. After the mounting ring 1 is disassembled from the shaft, the stud 12 is rotated out of the fixing block 3 by an auxiliary tool to separate it from the fixing block 3 and the blade 7, thereby facilitating the upward pulling of the blade 7 so that the plug block 8 at the bottom can be separated from the slot 5 on the fixing block 3, and the positioning piece 10 is separated from the positioning block 6, thereby quickly completing the disassembly of the blade 7 and the mounting ring 1, preventing the inconvenience of disassembly and replacement caused by the welding fixing method, thereby reducing the cost and inconvenience of replacement.

[0025] In this embodiment, the fastening ring 13 is first taken out of the first fixing groove 4 and the stud 12, and the stud 12 is rotated outward from the fixing block 3 by an auxiliary tool to disengage it from the first fixing groove 4 on the fixing block 3, and then the blade 7 is pulled upward to disengage the plug block 8 at its bottom from the slot 5 on the fixing block 3. At the same time, the positioning pieces 10 arranged on both sides of the blade 7 will be separated from the positioning blocks 6 arranged on one side of the fixing block 3 when the blade 7 is pulled, thereby completing the disassembly of the blade 7 and the mounting ring 1, making it easier to replace and repair it. In addition, a wear-resistant layer 14 and a reinforcing rib 15 are respectively arranged in the blade 7, which can improve the overall strength and wear resistance of the blade 7, thereby increasing its service life and avoiding the need to replace the blade 7 for a long time, which leads to increased costs.
[0026] In a further preferred embodiment of the present invention, Figure 2 As shown, the outer wall of the fastening ring 13 is movably connected to the inner wall of the first fixing groove 4, and the fastening ring 13 is a hard rubber fastening ring.
