The inside of the stirring tank can be flushed through the spray pipe and spray hole, thereby avoiding the adhesion of thick cement on the inner wall of the stirring tank and making it more convenient to use later.

[0003] The applicant believes that the above device still has the following deficiencies that need to be improved: first, the cleaning is only for the stirring tank, and the cleaning of the conveying tank and the feed hopper is not involved; second, the feed hopper is designed as an open type, so there is inevitably dust problem during discharging. Even if a sealing cover is added to the feed hopper, a large amount of dust will be generated and dispersed upward when a large amount of material is discharged into the feed hopper at the same time, and the dispersed dust will invade into the batching pipe in the opposite direction, thereby affecting the discharging speed; third, the clean water is conveyed into the connecting pipe through the first water inlet pipe at the bottom, and the first water inlet pipe and the connecting pipe are connected in rotation. Therefore, it is difficult to avoid the invasion of material from the rotating connection into the first water inlet pipe or the connecting pipe during normal stirring, causing blockage.
