The upper end of the second vertical rod 63 is fixedly connected to the upper end of the first vertical rod 61 through a connecting rod 62, and the lower end of the second vertical rod 63 is threadedly sleeved on the screw rod 64. When the second motor 65 drives the screw rod 64 to rotate, under the sliding and limiting action of the limiting sleeve 15, it can drive the second vertical rod 63 to move up and down, and then drive the first vertical rod 61 to move up and down through the connecting rod 62, realizing the up and down movement of the lifting plate 5 inside the stirring tank 1.

[0026] The cleaning ring 3 is provided with a fixing component for fixing the cleaning ring 3 at the movable opening 14 or on the first vertical rod 61. Specifically, the fixing component includes a telescopic cylinder 71 (which can adopt an oil cylinder structure), a housing 8, and a first sliding rod 72. The telescopic rod is horizontally installed above the cleaning ring 3 towards the first vertical rod 61 side. The housing 8 is fixed on the cleaning ring 3. A first sliding groove 81 is horizontally opened inside the housing 8 along the length direction of the telescopic rod, and two second sliding grooves 82 are horizontally opened in communication with each other perpendicular to the first sliding groove 81; a clamping groove 610 is opened on the side wall of the lower end of the first vertical rod 61; the first sliding rod 72 is slidably clamped in the first sliding groove 81, and one end of it is fixedly connected to the piston rod of the telescopic cylinder 71, and the other end is clamped and matched with the clamping groove 610 on the first vertical rod 61. Wedge-shaped blocks 721 are fixedly provided on both the left and right sides of the middle of the first sliding rod 72.

The piston cylinder of the telescopic cylinder 71 drives the first sliding rod 72 to extend, so that the end of the first sliding rod 72 can be arranged in the card slot 610 of the first vertical rod 61. At the same time, under the elastic force of the spring 732, the second sliding rod 73 retracts into the second sliding groove 82, so that the end of the second sliding rod 73 disengages from the snap ring 16, releasing the connection between the cleaning ring 3 and the movable port 14, enabling the cleaning ring 3 to descend into the mixing tank 1 along with the lifting plate 5 and the first vertical rod 61, and cooperating with the high-pressure nozzle 4 to spray high-pressure water in all directions, thereby effectively flushing and cleaning the inner wall of the mixing tank 1, making the cleaning of the inside of the mixing tank 1 simpler and more convenient. After the cleaning is completed, the lifting drive mechanism drives the cleaning ring 3 to rise to the uppermost end through the first vertical rod 61, and by using the contraction of the telescopic cylinder 71, the first sliding rod 72 and the second sliding rod 73 are driven to reset, releasing the fixation of the cleaning ring 3 on the first vertical rod 61 and re-fixing it at the movable port 14 of the mixing tank 1 for the next mixing use.

[0028] When using the utility model, the mortar raw materials are injected into the mixing tank 1 through the feed port 11, and the first motor 21 drives the mixing paddle 23 to rotate for sufficient mixing operation, and then the mortar is discharged through the control valve 12. When it is necessary to clean the inside of the mixing tank 1, the lifting drive mechanism drives the lifting plate 5 to support below the cleaning ring 3 through the second vertical rod 63, the connecting rod 62 and the first vertical rod 61. By using the action of the telescopic cylinder 71, the first sliding rod 72 and the second sliding rod 73 are driven to cooperate, releasing the fixed connection between the cleaning ring 3 and the movable port 14 and fixing the cleaning ring 3 in the card slot 610 of the first vertical rod 61 at the same time. The cleaning ring 3 descends into the mixing tank 1 along with the first vertical rod 61, and cooperates with the high-pressure nozzle 4 to spray high-pressure water in all directions, thereby effectively flushing and cleaning the inner wall of the mixing tank 1, making the cleaning of the inside of the mixing tank 1 simpler and more convenient. After the cleaning is completed, the lifting drive mechanism acts to drive the cleaning ring 3 to rise and reset, and by using the action of the telescopic cylinder 71, the first sliding rod 72 and the second sliding rod 73 are driven to reset, releasing the fixation of the cleaning ring 3 on the first vertical rod 61 and re-fixing it at the movable port 14 of the mixing tank 1 for the next mixing use.
