[0025] When in use, the concrete distribution vehicle 1 is moved to the concrete distribution location, and the concrete is placed in the mixing drum 30 through the feed port 34. The mixing motor 33 is started, and the mixing motor 33 rotates to drive the stirring and mixing rod 31 to rotate. The stirring and mixing rod 31 rotates to stir the concrete in the mixing drum 30, effectively preventing the concrete from segregating. The rotation of the stirring and mixing rod 31 drives the lever gear 37 to rotate, and the lever gear 37 rotates to drive the lever belt 38 to rotate. The lever belt 38 rotates to drive the moving gear 36 to rotate, and the moving gear 36 rotates to drive the distribution vehicle 1 to move forward, and the concrete is started. The concrete pump 32 draws the concrete from the mixing cylinder 30 and transfers it to the anti-splash cylinder 18, and the concrete falls through the anti-splash cylinder 18 to start the defoaming motor 8. The rotation of the defoaming motor 8 drives the driving rod 9 to rotate, and the rotation of the driving rod 9 drives the linkage rod 10 to rotate. The rotation of the linkage rod 10 drives the limit rod 11 and the transmission rod 12 to rotate, and the rotation of the transmission rod 12 drives the connecting rod 13 to rotate. The rotation of the connecting rod 13 drives the defoaming trigger column 7 to rise and fall. The defoaming column rises and falls to vibrate the concrete, effectively discharge the bubbles in the concrete, make the concrete more dense, and improve the concrete. Strength and durability ensure that the concrete is evenly distributed. When the defoaming column descends, the rotation angle of the driving rod 9 is much smaller than the rotation angle when the defoaming column rises. Therefore, the technical effect of fast insertion and slow extraction can be achieved, which effectively reduces the chance of bubbles being brought into the concrete. When the defoaming trigger column 7 rises and falls, the trigger pressure plate 14 is driven to rise and fall. The trigger pressure plate 14 descends to squeeze the pressure plate 23. The pressure plate 23 is pressed down. At this time, the spring 22 is extended, and the pressure plate 23 descends to drive the torsion column 24 to descend. After the torsion column 24 descends with the pressure plate 23 and enters the torsion groove 19, the torsion column 24 The spiral structure of the groove 19 drives the anti-splash tube 18 to rotate. At this time, the scraper plate 25 fits tightly against the inner wall of the anti-splash tube 18 to scrape off the adhered concrete, triggering the pressure plate 14 to rise, and the squeezing force on the pressure plate 23 disappears. The pressure plate 23 rises and resets under the action of the spring 22. The rising of the pressure plate 23 drives the torsion column 24 to rise. Under the action of the torsion groove 19, the torsion column 24 rises and drives the anti-splash tube 18 to rotate and reset, thereby achieving the technical effect of reciprocating scraping and cleaning the anti-splash tube 18. The above is the specific working process of the present invention, and this step can be repeated the next time it is used.
