[0026] As Figure 1-Figure 3 shown, a concrete mixer proposed by the present utility model includes a body 1, an anti-blocking mechanism and a stirring mechanism. The top and bottom of the body 1 are respectively communicated with a feed pipe 2 and a discharge pipe 3. A hopper 4 is arranged at the top of the feed pipe 2. An anti-blocking mechanism for preventing blockage during feeding and discharging is arranged outside between the feed pipe 2 and the discharge pipe 3. A stirring mechanism for stirring concrete is arranged inside the body 1, and it has a linkage assembly for driving the anti-blocking mechanism to operate.
[0027] As Figure 2 shown, the anti-blocking mechanism includes a guide frame 5, a sliding frame 6 and an impact frame 8. The cross-section of the guide frame 5 is U-shaped, and two groups of it are symmetrically arranged, respectively located at the top and bottom of one side of the body 1. A sliding frame 6 is slidably arranged between the two groups of guide frames 5. The structure of the sliding frame 6 is C-shaped, and limit sleeves 7 located outside the guide frame 5 are arranged on both sides of its vertical section. One ends of the two horizontal sections of the sliding frame 6 are respectively connected with an impact frame 8. The impact frame 8 is arranged in a frame structure, and an opening is provided on one side of it. Rubber blocks 9 are arranged on both sides of the opening.
[0028] Among them, the feed pipe 2 and the discharge pipe 3 are respectively located at the openings of the impact frame 8.
[0029] As Figure 1 shown, a valve 16 is arranged on the discharge pipe 3, and a handle is arranged outside the valve 16. The valve 16 is opened through the handle, so as to conduct the discharge pipe 3.
[0030] Embodiment 2
[0031] As Figure 1-Figure 3 shown, a concrete mixer proposed by the present utility model, on the basis of the above embodiment, this embodiment also details the detailed structures of the stirring mechanism and the linkage assembly, as well as their connection manners with the body 1.
[0032] As Figure 3As shown, the mixing mechanism includes a motor 10, a rotating shaft 11 and a mixing blade 12. The motor 10 is installed on the side of the body 1 away from the sliding frame 6, and its output end is connected to the rotating shaft 11 that passes through the body 1. The mixing blade 12 is arranged on the outside of the rotating shaft 11 located in the body 1. The motor 10 is used to drive the rotating shaft 11 and the mixing blade 12 to rotate, thereby mixing the concrete in the body 1.
