8. A method of using the constructional concrete mixing apparatus as defined in claim 1, comprising the steps of:

firstly, starting: liquid is filled in the buffer cavity (43), then the first motor (3) is started, the first motor (3) drives the first gear (4) to rotate, the first gear (4) rotates to drive the second gear (6) to rotate, the second gear (6) rotates to drive the first rotating shaft (5) to rotate, the first rotating shaft (5) rotates to drive the first rotating disc (26) to rotate, and the first rotating disc (26) rotates to drive the second rotating disc (8) to rotate through the connecting column (14).

Secondly, stirring: first carousel (26) promote push rod (68) through lug (7) when rotatory, push rod (68) drive commentaries on classics board (69) are rotatory, and then make connecting rod (71) pulling elevator (13) descend, elevator (13) drive fourth spring (47) when descending and hold up power, stirring vane (61) reciprocate this moment and stir the concrete in box (46), because commentaries on classics board (69) are by the continuous drive rotation of lug (7), lead to long press switch (63) can't be in long and press the state this moment, therefore can not be triggered.

Thirdly, scraping materials: after the push rods (68) are sequentially pushed by the plurality of convex blocks (7), the push rods (68) slide along the outer side of the first rotary disc (26), in the process of sliding, the supporting plate (67) pushes the semicircular block (24), the semicircular block (24) pushes the first sliding plate (40) through the stabilizing rod (23), the first sliding plate (40) is pushed and then drives the main shaft (31) to slide through the sliding rod (44), at the moment, the first electromagnet (39) adsorbs the first metal plate (37), the clamping column (29) is clamped at the clamping hole (32), the protruding part (12) pushes the first pressure rod (11) to ascend, the first pressure rod (11) ascends to push the fixed block (10) to ascend, the fixed block (10) ascends to drive the convex blocks (7) to ascend, the push rods (68) are located between the convex blocks (7) and the outer side of the first rotary disc (26) and slide along the first rotary disc (26), and at the moment, the rotary plate (69) does not rotate for a, when the long-press switch (63) is triggered, the air cylinder (54) drives the third fixing plate (55) to lift and scrape off the cement on the inner wall of the box body (46).

Fourthly, resetting: when the push rod (68) slides, the second pressure rod (35) is pressed to descend, the second pressure rod (35) descends to enable the second electromagnet (27) to adsorb the second metal block (28), and further enable the clamping column (29) to be separated from the clamping hole (32), but at the moment, the main shaft (31) cannot reset because the first electromagnet (39) adsorbs the first metal plate (37), at the moment, along with the sliding of the push rod (68), when the push rod (68) presses the first travel switch (25), the first electromagnet (39) and the second electromagnet (27) are disconnected briefly, when the first electromagnet (39) is disconnected, the first spring (41) pushes the main shaft (31) to reset rapidly, and further the lug (7) descends to be attached to the outer side of the first rotating disc (26) again, when the second electromagnet (27) is disconnected, liquid is arranged in the buffer cavity (43), so that the speed of the third spring (15) pushing the second sliding plate (76) is slightly slower, further prevent the clamping column (29) from being clamped into the clamping hole (32) to cause resetting failure, and at the moment, the rotating plate (69) can be pushed to rotate through the lug (7) along with the rotation of the first rotating disc (26).
