[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 As shown, in this example, the stirring device for water reducing agent includes a mounting plate 1, a driving motor 4, a stirring paddle 3, and a bracket 2. The bracket 2 is fixed on the mounting plate 1, and the driving motor 4 and the telescopic mechanism 5 are installed on the bracket 2. Specifically, the bracket 2 is in an I-shape, and the two horizontal ends at the top are relatively arranged at both sides of the longitudinal end and are arranged in a staggered manner. Figure 1 In the state shown, a driving motor 4 is installed at the upper horizontal end on the right side, and a telescopic mechanism 5 is installed at the upper horizontal end on the left side. The telescopic mechanism is such as a cylinder, an electric telescopic rod, a hydraulic cylinder, etc.

[0021] The horizontal end at the bottom is fixed to the mounting plate 1, such as by bolts. A slide groove 21 is formed at the middle position of the longitudinal end of the bracket 2 along its length direction. The slide groove 21 is slidably connected to the slide seat 7. One end of the slide seat 7 is fixed to the output end of the telescopic mechanism 5, such as by a connecting rod 6. The connecting rod 6 is fixed at the end of the slide seat 7, and the other end of the connecting rod 6 is fixed to the output end of the telescopic mechanism 5.

[0022] The output end of the driving motor 4 is fixed to the connecting shaft 9. The connecting shaft 9 is in the shape of a quadrangular prism and the barrel cavity of the connecting cylinder 12 below it is also in the shape of a quadrangular prism. The connecting shaft 9 is inserted into the barrel cavity of the connecting cylinder 12 to form a sliding key connection. During the rotation of the connecting shaft 9, the connecting cylinder rotates synchronously, and the two can slide relative to each other along the axial direction.

[0023] The end of the connecting tube 12 extends into the sleeve 10 and its peripheral wall is connected to the cavity wall of the sleeve 10 by a bearing to form a rotational fit. The connecting rod 2 8 is fixed at the end of the slide 7 and the other end of the connecting rod 2 8 is fixed to the sleeve 10. The slide is moved by the telescopic mechanism, and the sleeve 1 is moved synchronously, which corresponds to the up and down movement of the connecting tube.

[0024] The head end of the connecting tube 12 extends from the sleeve 10 and fixes the ring body 13. The outer diameter of the ring body 13 is larger than the diameter of the sleeve 10. The ball 14 is arranged between the bottom surface of the ring body 13 and the end surface of the sleeve 10. If the ball is pre-placed in the groove at the end surface of the sleeve, the ball abuts against the bottom surface of the ring body above, which helps to reduce the rotational resistance and improve the bearing capacity of the connecting tube.

[0025] A hole is formed in the middle of the mounting plate 1 and a sleeve 15 is fixed at the hole. The tail end of the connecting tube 12 passes through the sleeve 15 and rotates to fit. Sealing rings 16 are installed at both ends of the sleeve 15 to improve the sealing performance.

[0026] The rear end of the connecting tube 12 is connected to the stirring paddle 3 below the mounting plate 1 , such as the front end of the shaft 31 of the stirring paddle 3 is inserted into the groove at the rear end of the connecting tube 12 and fixed by bolts or pins to rotate synchronously.

[0027] When in use, the mounting plate can be used as a tank cover to fix the tank body, so as to drive the motor to drive the connecting shaft to rotate, and the connecting tube and the stirring paddle to rotate synchronously. When the height needs to be adjusted, the telescopic mechanism moves the slide seat, which causes the sleeve to move accordingly, and the connecting tube moves synchronously relative to the connecting shaft, and the stirring paddle moves synchronously, so that the height can be adjusted.

[0028] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
