Description

Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to a reducer stirrer. Background Art

[0002] The reducer agitator is a device that combines the functions of a reducer and an agitator. It is mainly used to stir liquid or solid mixtures. It converts the high-speed rotation of the motor into the low-speed, high-torque rotation of the agitator, thereby achieving uniform stirring of the liquid or solid mixture, making the stirring process more efficient and smooth.

[0003] In some large mixing equipment, the mixing container is large, so the corresponding stirring rod is also longer, so that the stirring rod can reach the bottom and edge of the container to achieve more uniform mixing. However, due to the long stirring rod, it is easy to shake when it is fixed to the reducer agitator. This not only affects the mixing effect, but also may cause damage to the related structure.

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] according to Figure 1-4 The utility model provides a reducer agitator, comprising: a housing 1, a runner 2, a rotating rod 3, a connecting rod 4, a coupling 5, a fixed bearing 6, a baffle 7, and a clamping ring 8.

[0022] A connecting cavity 11 is provided in the housing 1. The rotating wheel 2 is disposed in the connecting cavity 11. The rotating wheel 2 has a connecting opening 21. The rotating rod 3 passes through the connecting opening 21.

[0023] When installing the rotating rod 3, the rotating wheel 2 is set in the connecting cavity 11, the rotating rod 3 is passed through the connecting port 21, and then fixed. When the rotating rod 3 rotates, the wall of the connecting port 21 forms a radial constraint on the rotating rod 3, preventing the rod from moving in the direction of the vertical axis. The connecting port 21 has a certain length, providing a continuous support surface for the rotating rod 3 within a certain distance. This continuous support disperses the force exerted by the rotating rod 3 on the wall of the connecting port 21 when rotating, preventing local excessive pressure from causing shaking. That is, this structure is conducive to improving the stability of the rotating rod 3 and preventing the rotating rod 3 from shaking when rotating.

[0024] The coupling 5 is arranged in the connecting cavity 11. One side of the coupling 5 is connected to the connecting rod 4, and the other side is connected to the rotating rod 3.

[0025] When assembling the present invention, the connecting rod 4 is connected to the motor, and then connected to the rotating rod 3 through the coupling 5. Starting the motor can rotate the connecting rod 4, and the connecting rod 4 then drives the rotating rod 3 to rotate through the coupling 5. The coupling 5 generally also contains an elastic element (such as rubber, nylon, etc.), which can absorb and disperse vibration energy when subjected to vibration, thereby reducing the impact of vibration on the equipment, that is, it can further avoid the adverse effects caused by the shaking of the rotating rod 3.

[0026] One end of the rotating rod 3 passes through the rotating wheel 2, and the other end is provided with a stirring rod 31. The rotating wheel 2 includes: a friction wheel 22 and a rotating wheel 23. The friction wheel 22 is arranged on the side of the rotating wheel 23 away from the stirring rod 31. The fixed bearing 6 is arranged on the side of the housing 1 close to the stirring rod 31. The fixed bearing 6 is sleeved on the rotating wheel 23. The baffle 7 is arranged on the side of the fixed bearing 6 away from the stirring rod 31. The baffle 7 is arranged in the connecting chamber 11. The baffle 7 has a through hole 71. The friction wheel 22 includes: a small wheel 221 and a large wheel 222. The radius of the through hole 71 is larger than that of the small wheel 221. The small wheel 221 is connected to the large wheel 222. The small wheel 221 passes through the through hole 71. The large wheel 222 conflicts with the baffle 7. The rotating rod 3 also includes: a thin rod 32 and a thick rod 33. The thin rod 32 is connected to the thick rod 33. The stirring rod 31 is arranged on the thick rod 33. The thick rod 33 passes through the rotating wheel 23 on the side away from the stirring rod 31. The end of the thick rod 33 away from the stirring rod 31 conflicts with the small wheel 221. The thin rod 32 passes through the conflict wheel 22 on the end close to the thick rod 33. The thin rod 32 includes: a slot 321 and a collar 322. The slot 321 is provided on the side of the large wheel 222 away from the baffle 7. The collar 322 is provided on the side of the slot 321 away from the large wheel 222. The collar 8 corresponds to the slot 321. The shell 1 also includes: an end cover 12. The end cover 12 is provided on the side of the shell 1 away from the stirring rod 31. A support bearing 121 is provided on the end cover 12. The support bearing 121 is sleeved on the connecting rod 4.

[0027] The rotating wheel 2 includes a contact wheel 22 and a rotating wheel 23, so that the two rotating wheels 2 simultaneously prevent the rotating rod 3 from rotating, thereby enhancing the stability of the rotating rod 3. The fixed bearing 6 is sleeved on the rotating wheel 23, so that the rotating wheel 23 is fixed on the fixed bearing 6 and can rotate relative to the fixed bearing 6. When assembling the present invention, the small wheel 221 of the interference wheel 22 passes through the through hole 71, and then the end of the rotating rod 3 away from the stirring rod 31, that is, the thin rod 32, passes through the rotating wheel 23, and then passes through the through hole 71 and the interference wheel 22, and is connected to the coupling 5, so that the rotating rod 3 is fixed, and at the same time, the large wheel 222 is in conflict with the baffle 7, and the small wheel 221 is in conflict with the thick rod 33. At this time, the groove 321 is on the side of the large wheel 222 away from the baffle 7, and the ring 322 is set on the side of the groove 321 away from the large wheel 222. Open the end cover 12 and put the clamping ring 8 into the groove 321. At this time, one end of the clamping ring is in conflict with the collar 322, and the other end is in conflict with the large wheel 222, so that the two ends of the large wheel 222 are respectively in conflict with the clamping ring 8 and the baffle 7, so that the large wheel 222 is fixed, that is, the interference wheel 22 is fixed. When the rotating rod 3 rotates, it can drive the interference wheel 22 and the rotating wheel 23 to rotate. The friction force of the rotating wheel 23 when rotating is mainly the action force between the fixed bearing 6, and the friction force of the interference wheel 22 when rotating is mainly the friction force between the baffle 7. If the rotating rod 3 does not drive the interference wheel 22 and the rotating wheel 23 to rotate, the friction force of the rotating rod 3 when rotating is the friction force between the wall of the connecting cavity 11. In this process, the contact area between the rotating rod 3 and the rotating wheel 2 is larger, and the friction force is also correspondingly larger. The resistance received during rotation is greater, and it is easier for the interaction to cause shaking. The friction force of the rotating rod 3 of the utility model is smaller when rotating, which reduces the burden on the motor while preventing excessive force from causing shaking of the rotating rod 3 or damage to part of the equipment structure. The radius of the through hole 71 is larger than the small wheel 221, so that when the interference wheel 22 rotates with the rotating rod 3, the small wheel 221 will not contact the side wall of the through hole 71 and cause friction. At the same time, since the thin rod 32 first passes through the rotating wheel 23 and then passes through the interference wheel 22, the thin rod 32 will be limited by the connecting port 21 when passing through the rotating wheel 23. When it subsequently moves to pass through the interference wheel 22, the thin rod 32 will not move in a direction other than the axis. Since the radius of the through hole 71 is larger than the small wheel 221, the position of the interference wheel 22 is difficult to fix. According to the above content, the interference wheel 22 can be adjusted to a suitable position according to the thin rod 32 so that the thin rod 32 just passes through the interference wheel 22, which is conducive to the positioning of the interference wheel 22.

[0028] The working principle and use process of this utility model:

[0029] During assembly of the present invention, the end cover 12 is opened, and the rotating rod 3 is moved away from one end of the stirring rod 31, that is, the thin rod 32, and is passed through the rotating wheel 23 along the side of the fixed bearing 6 provided along the shell 1, and then through the through hole 71. Then, the position of the interference wheel 22 is adjusted so that the thin rod 32 passes through the interference wheel 22 and is connected to the coupling 5 to fix the rotating rod 3. Then, the small wheel 221 of the interference wheel 22 is moved toward the thick rod 33 so that the small wheel 221 conflicts with the thick rod 33, and at the same time, the large wheel 222 conflicts with the baffle 7. Then, the clamping ring 8 is put into the clamping groove 321, and then one end of the connecting rod 4 is fixed to the coupling 5. The end cover 12 is closed, and the support bearing 121 is put on the connecting rod 4, and then the connecting rod 4 is connected to the motor. When the utility model needs to be used, start the motor, click to drive the connecting rod 4 to rotate, the connecting rod 4 drives the rotating rod 3 to rotate through the coupling 5, and at the same time the resistance wheel 22 and the rotating wheel 23 rotate together with the rotating rod 3, and the rotating rod 3 then drives the stirring rod 31 to rotate for stirring.

[0030] To sum up, the utility model is provided with a shell, a rotating wheel and a rotating rod. The rotating wheel is arranged in the shell, and the rotating rod passes through the rotating wheel. When the rotating rod rotates, the rotating rod is difficult to shake or vibrate significantly due to the limitation of the inner wall of the rotating wheel, thereby avoiding poor stirring effect or even damage to the equipment structure.
