step 3: after all the raw materials of the polycarboxylate water reducer are added into a stirring cup (6) and are uniformly mixed to prepare the polycarboxylate water reducer, the polycarboxylate water reducer moves to a driven wheel (5) and turns over, so that the polycarboxylate water reducer is poured into a corresponding container, and when the cup body (601) turns over to the lower part of the conveying belt (3), the movable plate (205) inclines to the edge of the conveying belt (3) under the action of gravity;
step 4: when the stirring cup (6) moves to the area where the partition plate (4) is located, the partition plate (4) is arranged between the movable plate (205) and the conveying belt (3) in an isolating mode, so that water mist flowing transversely can wash the cup body (601) and can be isolated from the conveying mechanism by the partition plate (4);
step 5: the stirring cup (6) turns over again when moving to the driving wheel (1), and the raw materials of the polycarboxylate water reducer are added again.
4. The conveying and mixing mechanism for preparing the polycarboxylate water reducer as claimed in claim 2, wherein in the area of the partition plate (4), the stirring cup (6) is washed with water mist and dried with hot air; in the step 3, the inclination angle of the movable plate (205) is 30 degrees; the stepping advancing distance of the stirring cups (6) is the same as the interval between adjacent stirring cups (6), and the time interval of the stepping advancing is not shorter than the longest adding time of the raw materials of the polycarboxylate water reducer; the volume of the stirring cup (6) is not more than 4L.
