[0033] See also Figure 2 In order to reduce the labor intensity of the staff, the lifting mechanism 5 in this embodiment includes a support frame 51, an electric push rod 52, a fixed box 53, a driving member 54 and a containing box 55. The electric push rod 52 is arranged on the inner bottom wall of the support frame 51 and is used to raise the height of the fixed box 53. The output shaft of the electric push rod 52 is fixed to the upper surface of the fixed box 53.

The driving member 54 is arranged in the inner cavity of the fixed box 53 and is used to adjust the angle of the containing box 55. The left side of the containing box 55 is connected to the left side of the fixed box 53 by a hinge.

The threaded sleeve 543 and the threaded rod 541 are threadedly connected. The output shaft of the driving motor 542 rotates, thereby driving the threaded rod 541 to rotate. The rotation of the threaded rod 541 causes the threaded sleeve 543 threadedly connected to its surface to move. The two hinge shafts 545 are distributed on the upper surface of the threaded sleeve 543 and the right end of the lower surface of the holding box 55. The hinge rod 544 is set between the two hinge shafts 545. The movement of the threaded sleeve 543 drives the hinge shaft 545 fixed on its upper surface to move, thereby changing the angle of the hinge rod 544, so that the hinge shaft 545 fixed on the lower surface of the holding box 55 drives the angle of the right side of the holding box 55 to rise, so that the cement in the inner cavity of the holding box 55 can be poured out, so that the cement can fall on the guide plate, and the remaining cement in the inner cavity of the holding box 55 can be manually shoveled out by the staff and then enter the mixing tank 1 through the through hole.

[0037] See also Figure 3-4 In order to reduce pollution to the environment, the dust extraction mechanism 6 in this embodiment includes an installation box 61, a partition 62, a fan 63, a feed pipe 64 and an air diffusion hood 65. The installation box 61 is arranged at the right end of the upper surface of the mixing tank 1 and is used to collect dust. The partition 62 is arranged in the middle of the inner bottom wall of the installation box 61 and is used to block the fan 63 and dust.

[0038] In this embodiment, the upper surface of the installation box 61 is hinged with a sealing cover through a door hinge, the height of the partition 62 is equal to the height of the inner cavity of the installation box 61, the air inlet end of the fan 63 passes through the partition 62 and extends to the right side of the partition 62, and the inner cavity of the air inlet end of the fan 63 is fixed with a dust-blocking net.

[0039] The working principle of the above embodiment is:

[0040] (1) When lifting cement, the worker first shovels the cement into the inner cavity of the holding box 55, then starts the electric push rod 52, the output shaft of the electric push rod 52 moves upward, and moves the fixed box 53 upward until it moves to the upper side of the guide plate, then stops the electric push rod 52, starts the drive motor 542, and the output shaft of the drive motor 542 rotates, thereby driving the threaded rod 541 to rotate, and the rotation of the threaded rod 541 causes the threaded sleeve 543 threadedly connected to its surface to move, and the movement of the threaded sleeve 543 drives the hinge shaft 545 fixed on its upper surface to move, thereby changing the angle of the hinge rod 544, so that the hinge shaft 545 fixed on the lower surface of the holding box 55 drives the angle of the right side of the holding box 55 to rise, so that the cement in the inner cavity of the holding box 55 can be poured out, so that the cement can fall on the guide plate, and the remaining cement in the inner cavity of the holding box 55 can be manually shoveled out by the worker, and then enter the mixing tank 1 through the through hole.

[0041] (2) When the cement is poured out, there will be a lot of dust. In order to reduce the pollution to the environment, the fan 63 is started. The air inlet end of the fan 63 generates negative pressure in the inner cavity of the installation box 61, and then the dust floating in the air is sucked into the inner cavity of the installation box 61 through the feed pipe 64 and the air expansion hood 65, so that the dust can be collected for reuse.
