[0026] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0027] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0029] like Figure 1 to Figure 4 As shown, the present embodiment proposes a revolving body structure for a vertical axis planetary mixer, the vertical axis planetary mixer comprises: an equipment housing 1, a driving motor 2, a reducer 3, at least one driving motor 2 is arranged on the top of the equipment housing 1, and each driving motor 2 is connected to a reducer 3 at the bottom; a revolving body structure 4 is arranged in the equipment housing 1; the revolving body structure 4 comprises a primary revolving body 41 and a secondary revolving body 42; the reducer 3 is meshed with the upper gear ring of the primary revolving body 41, and the lower gear of the primary revolving body 41 is meshed with the secondary revolving body 42; the secondary revolving body 42 is meshed with a plurality of autorotating body structures 5, and a stirring component 6 is connected to the bottom of the autorotating body structure 5;
[0030] When the revolving structure 4 rotates under the power of the driving motor 2 and the reducer 3, the primary revolving body 41 drives the driving motor 2, the reducer 3 and the secondary revolving body 42, and the secondary revolving body 42 drives the self-rotating structure 5 and the stirring component 6 to revolve around the central axis of the equipment housing 1 in the equipment housing 1; the secondary revolving body 42 is circumferentially provided with a plurality of self-rotating structures 5, and the self-rotating structure 5 revolves around the center of the secondary revolving body 42; the bottom of the self-rotating structure 5 is connected to the stirring component 6, and the self-rotating structure 5 revolves around the secondary revolving body 42 while driving the stirring component 6 to rotate.
[0031] When working, the driving motor 2 converts electricity into power and transmits it to the reducer 3, which adjusts the torque and speed and drives the revolving structure 4 to rotate through the gear transmission; the revolving structure 4 drives the self-rotating structure 5 and the stirring component 5 to revolve around the central axis of the equipment shell 1, and at the same time the self-rotating structure 5 drives the stirring component 6 to rotate, realizing the combined orbital and self-rotation motion of the stirring component 6, and completing the uniform stirring of the stirring material.
[0032] like Figure 2 and Figure 3 As shown, the primary revolving body 41 includes a revolving disk 411 and a central shaft 412; the revolving disk 411 is provided with a circle of gears along the inner wall; one side of the reducer 3 is meshed with the revolving disk 411, and the other side is meshed with the central shaft 412;
[0033] The central shaft 412 is arranged in the revolving disk 411 , and a circle of gears is arranged along the outer wall of the central shaft 412 . The upper part of the outer wall gear of the central shaft 412 meshes with the gear of the reducer 3 , and the lower part of the outer wall gear meshes with the gear of the secondary revolving body 42 .
[0034] The primary revolving body 41 in the revolving body structure 4 is mainly responsible for driving the driving motor 2 and the reducer 3 to revolve around the central axis of the equipment housing 1, and at the same time transmits power to the secondary revolving body 42, driving the secondary revolving body 42 to rotate; the range of the primary revolving body 41 driving the driving motor 2 and the reducer 3 to revolve is inside the primary revolving body 41, so that the operation of the driving motor 2 and the reducer 3 is relatively stable, ensuring the stability of the equipment.
[0035] The center of the bearing of the central shaft 412 is hollowed out, and the outer diameter of the bearing of the central shaft 412 is equal to the linear distance between the two symmetrical drive motors and the housing. The cavity of the central shaft 412 can increase the space occupied by the middle of the device housing 1 and reduce the edge space; the reduction of the edge space can reduce the use of lubricating oil, thereby achieving the effect of cost saving.

[0038] During operation, the primary revolving body 41 drives the secondary revolving body 42 to rotate through gear transmission, simplifying the internal electromechanical design; with the central gear 421 as the active part and the multiple planetary gears 422 as the driven parts, a planetary reduction mechanism is formed when they rotate in the same direction, which can achieve a reduction effect and make the vertical axis planetary mixer run more stably.
[0039] like Figure 4 As shown, multiple self-rotating structures 5 can be arranged in the circumference of the planetary gear 422 as needed; the planetary gear 422 only needs to mesh with the gear of each self-rotating structure 5 on one side, so the planetary gear 422 can drive the self-rotating structure 5 to rotate through the gear, and the self-rotating structure 5 drives the stirring component 6 to rotate; when multiple stirring components 6 are needed, as long as the multiple stirring components 6 can rotate without interfering with each other, multiple self-rotating structures 5 can be arranged on the planetary gear 422 as needed, thereby increasing the number of stirring components 6 to meet the stirring requirements.
[0040] The above embodiments only express the preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model.
