At this time, the third linear drive component 340 is turned on, and the third linear drive component 340 is turned on to push out and move up the third output rod 341. The third output rod 341 moves upward to drive the movable plate 41 to move upward.

As the movable plate 41 rotates and moves upward continuously, the coarse aggregate of larger particles can be clamped between the movable plate 41 and the crushing plate 315. At this time, the movable plate 41 rotates, and the crushing plate 315 rotates in the opposite direction to crush the coarse aggregate of larger particles into small particles of coarse aggregate, and re-enters the mixing device 4 through the through hole. Then the third linear drive component 340 is reset, and the mixing device 4 continues to rotate to continue to rotate and mix the crushed aggregate with the concrete, by grinding part of the coarse aggregate of larger size into fine aggregate, the aggregate is sufficient to fill the aggregate gap, resulting in dense particles, avoiding the formation of free gaps, isolating the conditions for the generation of bubbles, reducing the generation of bubbles during concrete mixing, improving the mixing quality of concrete, and facilitating user use;

At this time, similarly, when the first rotary drive assembly 32 rotates, the second linear drive assembly 322, the block 3230, and the connecting piece 331 can drive the screw rod 330 to rotate. The rotation of the screw rod 330 drives the movable block 34 to move toward the left. The movement of the movable block 34 drives the third linear drive assembly 340 to move. The third linear drive assembly 340 moves The movement of the second rotating arm 365 causes the third shaft 360 to move through the first movable slot 30.

At this time, the movement of the third linear drive assembly 340 allows the mixing device 4 to move normally to the auxiliary device 5. The first rotary drive assembly 32 can shake the mixing device 4 during the process of repeatedly moving and resetting the mixing device 4, so as to avoid the free movement gaps between some aggregates, resulting in bubbles inside the aggregates, thereby improving the mixing quality of the device and facilitating the use of the user.

[0057] In the above steps, the second rotary drive assembly 50 can be turned on, and the second rotary drive assembly 50 is turned on to drive the second rotating shaft 500 and the adjusting arm 51 to rotate. The rotation of the second adjusting arm 51 drives the rotating rod 510 to rotate, and the rotation of the rotating rod 510 drives the return groove plate 52 to perform a linear reciprocating motion. The movement of the return groove plate 52 causes the right connecting plate 53 and the knocking plate 530 to perform a knocking motion on the surface of the mixing device 4. The knocking vibration is used to increase the density of the concrete, further reduce the generation of bubbles inside the concrete, and improve the mixing quality of the concrete. The movement of the left connecting plate 53 drives the piston plate 531 to repeatedly pump air and spray air to the outside in the storage bin 54. The internal air pressure of the storage bin 54 increases, and the gas is sprayed out through the output pipe 540 and the spraying plate 542. Since the gas is heated by the heater 541 and sprayed on the outer surface of the mixing device 4, its surface temperature rises, thereby avoiding the slump of the concrete mixing, thereby further improving the mixing quality of the concrete, which is convenient for users to use.
