Description

Technical Field

[0001] This utility model relates to the field of vertical shaft mixer technology, and in particular to a planetary gear structure for a vertical shaft mixer. Background Technology

[0002] Compared to traditional horizontal mixers, vertical shaft mixers have a more stable structure and a longer service life. However, existing vertical shaft mixers have the following drawbacks: the drive unit is generally located on the sun gear, and the planetary gears rotate through a fixed gear ring to drive the mixing rod to complete the mixing. Therefore, its transmission ratio is fixed, and the speed is controlled by the motor speed, resulting in a limited mixing speed. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a planetary gear structure for a vertical shaft mixer, which effectively solves the problem of a small mixing speed range.

[0004] The technical solution to the technical problem is: a planetary gear structure for a vertical shaft mixer, including a housing, a rotating ring rotatably arranged inside the housing, the rotating ring having an "H" shaped structure, a sun gear and a planet carrier rotatably arranged at the center of the rotating ring, planet gears meshing with the sun gear rotatably arranged on the planet carrier, a first internal gear ring meshing with the planet gears at the bottom of the rotating ring, a second internal gear ring at the upper part of the rotating ring, a first gear at the upper end of the sun gear, a second gear slidably arranged on the housing, the second gear being driven by a motor, and after the second gear slides, a pump meshes with the first gear or the second internal gear ring, forming a structure in which the motor drives the sun gear or the rotating ring to rotate.

[0005] Preferably, the inner side of the housing has a protrusion, and the outer side of the rotating ring has a groove. The protrusion and the groove cooperate to form a structure in which the housing and the rotating ring are rotatably connected.

[0006] Preferably, four planetary gears are evenly distributed on the outer side of the planet carrier.

[0007] Preferably, a groove is provided on the upper part of the housing, the rotating shaft of the second gear slides in the groove, a bracket is slidably provided on the upper part of the housing, the motor is fixed on the upper part of the bracket, and a hydraulic cylinder connected to the motor is provided on the upper part of the housing.

[0008] Preferably, the housing is provided with a first limiting rod that cooperates with the first gear and a second limiting rod that cooperates with the second internal gear ring. Connecting plates extend from both sides of the bracket, and inclined grooves are provided on the connecting plates. The upper end of the first limiting rod or the second limiting rod is provided with a pin inserted into the inclined groove, thus forming a structure in which the movement of the bracket drives the first limiting rod and the second limiting rod to rise and fall.

[0009] This invention features a simple and ingenious structure that is easy to use. By switching the active component of the planetary gear structure and changing the transmission ratio of the planetary gear structure, the mixing speed range of the mixer can be increased, thereby enabling it to be applied to the mixing of more materials and expanding its application range.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 It is known that a planetary gear structure for a vertical shaft mixer includes a housing 1, a rotating ring 2 rotatably disposed inside the housing 1, the rotating ring 2 having an "H" shaped structure, a sun gear 3 and a planet carrier 4 rotatably disposed at the center of the rotating ring 2, planetary gears 5 rotatably disposed on the planet carrier 4 and meshing with the sun gear 3, four planetary gears 5 evenly distributed on the outer side of the planet carrier 4, a first internal gear ring 6 meshing with the planetary gears 5 at the bottom of the rotating ring 2, a second internal gear ring 7 at the upper part of the rotating ring 2, a first gear 8 at the upper end of the sun gear 3, a second gear 9 slidably disposed on the housing 1, the second gear 9 being driven by a motor 10, and after the second gear 9 slides, the pump meshes with the first gear 8 or the second internal gear ring 7, forming a structure in which the motor 10 drives the sun gear 3 or the rotating ring 2 to rotate.

[0016] In practical use, this utility model

[0017] First, move the second gear 9 to mesh with the first gear 8 or the second internal gear ring 7. The motor 10 drives the second gear 9 to rotate, causing the first gear 8 or the second internal gear ring 7 to rotate. That is, the sun gear 3 or the rotating ring 2 acts as the active component, driving the planetary gear 5 to rotate. The stirring rod is set below the planetary gear 5 to achieve stirring of the material. By changing the speed of the motor 10, the stirring speed can be controlled.

[0018] Since the transmission ratio of the planetary gear structure is different when using the sun gear 3 or the rotating ring 2 as the driving component, the transmission ratio between the planetary gear 5 and the motor 10 can be expanded, increasing the range between the maximum and minimum stirring speeds, thereby expanding the application range.

[0019] A protrusion 11 extends from the inner side of the housing 1, and a groove 12 is provided on the outer side of the rotating ring 2. The protrusion 11 and the groove 12 cooperate to form a structure in which the housing 1 and the rotating ring 2 are rotatably connected.

[0020] A slide groove 13 is provided on the top of the housing 1. The rotating shaft of the second gear 9 slides in the slide groove 13. A bracket 14 is slidably provided on the top of the housing 1. The motor 10 is fixed on the top of the bracket 14. A hydraulic cylinder 15 is provided on the top of the housing 1 and connected to it. The hydraulic cylinder 15 drives the bracket 14 to move to realize the meshing of the second gear 9 with the first gear 8 or the second internal gear ring 7.

[0021] The housing 1 is provided with a first limiting rod 16 that engages with the first gear 8 and a second limiting rod 17 that engages with the second internal gear ring 7. The bracket 14 has connecting plates 18 extending from both sides. The connecting plates 18 have inclined grooves 19. The upper end of the first limiting rod 16 or the second limiting rod 17 is provided with a pin that is inserted into the inclined groove 19. This forms a structure in which the bracket 14 moves to drive the first limiting rod 16 and the second limiting rod 17 to rise and fall. After the first limiting rod 16 descends, it is inserted into the tooth gap of the first gear 8 to limit the first gear 8. Similarly, after the second limiting rod 17 descends, it can limit the second internal gear ring 7. That is, when the sun gear 3 is the driving component, the rotating ring 2 is fixed. Similarly, when the rotating ring 2 is the driving component, the sun gear 3 is fixed, thereby fixing the transmission ratio. This allows the planetary gear 5 to rotate under the drive of the motor 10, thereby realizing the stirring of materials.

[0022] The lifting and lowering of the first limiting rod 16 and the second limiting rod 17 are controlled by the inclined groove 19 on the connecting plate 18, which cooperates with the movement of the second gear 9. When the second gear 9 approaches the first gear 8, the first limiting rod 16 moves upward to disengage from the first gear 8, while the second limiting rod 17 moves downward to limit the second internal gear ring 7. Conversely, when the second gear 9 approaches the second internal gear ring 7, the first limiting rod 16 moves downward to limit the first gear 8, while the second limiting rod 17 moves upward to disengage from the second internal gear ring 7, ensuring smooth power transmission and stability of the planetary gear structure.

[0023] Compared with the prior art, this utility model has the following advantages: the motor can drive the sun gear or the rotating ring, thereby changing the transmission ratio of the planetary gear structure, increasing the output speed of the planetary gear, expanding the application range of the mixer, and enabling it to be applied to the mixing of more materials.
