It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a stirring device for water reducing agent production, comprising: a motor base 1 and a stirring device for concrete water reducing agent production with the motor base 1 installed, a stirring rod 2 is rotatably connected on the surface of the motor base 1, a motor 10 is fixed to the top of the motor base 1, the top of the stirring rod 2 extends out of the top of the motor base 1, a stirring rod support ring 3 is fixed on the rod body of the stirring rod 2 extending out of the top of the motor base 1, a ball groove 4 is opened at the bottom end of the stirring rod support ring 3, a steel ball 5 is rotatably connected in the ball groove 4, the bottom end of the steel ball 5 extends from the ball groove 4, and the steel ball 5 is rotatably connected to the top of the motor base 1, a plurality of groups of ball grooves 4 are provided, and the plurality of groups of ball grooves 4 are distributed circumferentially about the stirring rod 2.

[0023] During actual use, the weight on the stirring rod 2 is transferred to the steel ball 5 through the stirring rod support ring 3 and then to the motor base 1 which is rotatably connected to the ball groove 4, and is converted into pressure on the motor base 1. The motor base 1 is fixed at the top of the stirring barrel, so the motor base 1 can withstand greater pressure, thereby preventing the weight on the stirring rod 2 from being transferred to the drive shaft of the motor 10, causing the drive shaft of the motor 10 to be pulled out of the body of the motor 10 and causing damage to the motor 10. At the same time, when the stirring rod 2 rotates, the steel ball 5 can be rotatably connected to the top of the motor base 1, so that the stirring rod support ring 3 can rotate with the stirring rod 2. There is rolling friction between the steel ball 5 and the top of the motor base 1, which can prevent the stirring rod support ring 3 from directly contacting the motor base 1, resulting in excessive friction that affects the rotation of the stirring rod 2.

[0024] Embodiment 2

[0025] On the basis of Example 1, in order to enable the rotating shaft of the motor 10 to drive the stirring rod 2 to rotate, an axis groove 7 is opened at the top of the stirring rod 2, and the transmission shaft of the motor 10 is movably inserted in the axis groove 7, and a key groove 8 is opened on the inner wall of the axis groove 7 and the rotating shaft of the motor 10, and a flat key 9 is movably inserted in the key groove 8.

[0026] The transmission shaft of the motor 10 is inserted into the shaft groove 7 opened at the top of the stirring rod 2. Key grooves 8 are provided on the transmission shaft of the motor 10 and the inner wall of the shaft groove 7. One end of the flat key 9 is inserted into the key groove 8 opened on the transmission shaft of the motor 10, and the other end of the flat key 9 is inserted into the key groove 8 opened on the inner wall of the shaft groove 7. As a result, the transmission shaft of the motor 10 can drive the stirring rod 2 to rotate through the cooperation of the flat key 9 and the key groove 8 when rotating. At the same time, the stirring rod 2 and the transmission shaft of the motor 10 are no longer fixedly connected, thereby avoiding the weight of the stirring rod 2 being transferred to the transmission shaft of the motor 10.

[0027] Embodiment 3

[0028] On the basis of Example 2, in order to limit the steel ball 5, the ball groove 4 is movably connected with a clamping ring 6 in the opening set at the bottom end of the stirring rod support ring 3. The clamping ring 6 is annular in structure, and the inner ring of the clamping ring 6 matches the shape of the steel ball 5. The bottom end of the clamping ring 6 is flush with the bottom end of the stirring rod support ring 3, and the bottom end of the stirring rod support ring 3 is fixed with a limiting rod mounting cylinder 11, and a limiting rod 12 is movably inserted in the limiting rod mounting cylinder 11. A spring 13 is fixed at one end of the limiting rod 12 extending into the limiting rod mounting cylinder 11, and the other end of the spring 13 is fixed on the inner wall of the limiting rod mounting cylinder 11. The end of the limiting rod 12 away from the spring 13 extends from the surface of the limiting rod mounting cylinder 11, and the top of the part of the limiting rod 12 extending out of the limiting rod mounting cylinder 11 is against the bottom end surface of the clamping ring 6.

[0029] After the steel ball 5 is placed in the ball groove 4, first retract the two groups of limit rods 12 next to the group of ball grooves 4 completely into the limit rod mounting tube 11, so that the spring 13 is compressed, and then put the snap ring 6 into the ball groove 4, and then release the limit rod 12. The spring 13 pushes one end of the limit rod 12 out of the limit rod mounting tube 11 under the influence of its own elastic action, and the top of the part of the limit rod 12 extending out of the limit rod mounting tube 11 abuts against the bottom end of the snap ring 6, thereby limiting the snap ring 6 to the ball groove 4, and the snap ring 6 limits the steel ball 5 to the ball groove 4.

[0030] During actual use, the weight on the stirring rod 2 is transmitted to the steel ball 5 through the stirring rod support ring 3 and then to the motor base 1 which is rotatably connected in the ball groove 4, which is converted into pressure on the motor base 1. The motor base 1 is fixed at the top of the stirring barrel, so the motor base 1 can withstand greater pressure, thereby preventing the weight on the stirring rod 2 from being transmitted to the transmission shaft of the motor 10, causing the transmission shaft of the motor 10 to be pulled out of the body of the motor 10 and causing damage to the motor 10. At the same time, when the stirring rod 2 rotates, the steel ball 5 can be rotatably connected to the top of the motor base 1, so that the stirring rod support ring 3 can rotate with the stirring rod 2. There is rolling friction between the steel ball 5 and the top of the motor base 1, which can prevent the stirring rod support ring 3 from directly contacting the motor base 1, resulting in excessive friction and affecting the rotation of the stirring rod 2. The transmission shaft of the motor 10 is inserted into the shaft groove 7 opened at the top of the stirring rod 2, and key grooves 8 are opened on the transmission shaft of the motor 10 and the inner wall of the shaft groove 7. One end of the flat key 9 is inserted into the key slot 8 provided on the transmission shaft of the motor 10, and the other end of the flat key 9 is inserted into the key slot 8 provided on the inner wall of the slot 7, so that when the transmission shaft of the motor 10 rotates, the stirring rod 2 can be driven to rotate by the cooperation of the flat key 9 and the key slot 8. At the same time, the stirring rod 2 and the transmission shaft of the motor 10 are no longer fixedly connected, so as to avoid the weight of the stirring rod 2 being transferred to the transmission shaft of the motor 10. After the steel ball 5 is placed in the ball slot 4, the first The two groups of limit rods 12 next to the group of ball grooves 4 are completely retracted into the limit rod mounting tube 11, and the spring 13 is compressed. Then the retaining ring 6 is placed in the ball groove 4, and then the limit rod 12 is released. The spring 13 pushes one end of the limit rod 12 out of the limit rod mounting tube 11 under the influence of its own elastic action, and the top of the part of the limit rod 12 extending out of the limit rod mounting tube 11 abuts against the bottom end of the retaining ring 6, thereby limiting the retaining ring 6 to the ball groove 4, and the retaining ring 6 limits the steel ball 5 to the ball groove 4.
