Then, referring to fig. 8 and 9, when the rotation shaft 401 rotates slowly, the stirring structure 400 is driven to rotate slowly, and then the spline-connected sliding column 502 is driven to rotate slowly through the rotation shaft 401, and the second wedge block 602 rotates around the center of the sliding column 502, so that the first filter plate 504 and the second filter plate 505 are in parallel, and in the process of being in parallel, the first filter plate 504 also drives the first wedge block 601 and the second wedge block 602 to be in the same horizontal line, and when the second wedge block 602 rotates around the center of the sliding column 502, the second wedge block 602 contacts with the first wedge block 601, so that the first filter plate 504 and the second filter plate 505 shake up and down, the effect of the first filter plate 504 is improved, and at the same time, the sliding column 502 also shakes, so that the stirring blade 405 hinged through the cylindrical column 501 also shakes, and the stirring angle can be continuously changed, so that the mixing effect is improved;
When the concrete materials need to be thoroughly mixed, the micro motor 402 drives the pin shaft 404 to rotate continuously to enable the stirring blade 405 to be in a V shape and become parallel, so that the concrete in the bottom mixing of the stirring tank 1 can be thoroughly mixed, the mixing effect is improved, when the stirring blade 405 is in a parallel state, the cylindrical rod 501 is driven to be in a vertical state (refer to fig. 10 and 11 in detail), then the sliding column 502 is driven to continuously move towards the feeding plate 2 against the limiting column 503, then the limiting shaft 506 is driven to move, and the second filter plate 505 is driven to rotate around the limiting shaft 506, so that the second filter plate 505 slides inside the first filter plate 504, the first filter plate 504 and the second filter plate 505 are shown in fig. 10, and when the second filter plate 505 slides at the maximum distance on the first filter plate 504, the second filter plates 505 are not communicated with the filter openings 507 formed on the surface of the first filter plate 504, and the two groups of second filter plates 505 and the first filter plate 504 are in a reversed V shape, so that large sand and stones are received on the surface of the first filter plate 504 and roll off from the surface of the first filter plate 504, and finally fall into a collection box which is placed in advance outside the stirring box 1 from the diversion opening 3, thereby realizing the mixing of the concrete inside the stirring box 1 by the stirring structure 400, closing the channel of the first filter plate 504, providing enough time for the stirring structure 400 to mix the concrete, diversion the sand and stones which are not filtered out of the stirring box 1 to be collected outside, and controlling the opening of a discharge pipe through a control panel after the mixing is finished, so that the mixed concrete is discharged from the discharge pipe to a designated place;
When the stirring structure 400 is not used, the output shaft end of the micro motor 402 is controlled by the control panel to reversely rotate, the pin shaft 404 is driven to reversely rotate, and then the bottom of the stirring blade 405 is driven to face the bottom of the stirring tank 1, so that the sticky concrete on the surface of the stirring blade 405 is prevented from flowing to the bottom of the stirring tank 1, the sticky concrete on the surface of the stirring blade 405 is prevented from being static for a long time and being solidified, and the subsequent effect on concrete mixing is affected.
