As shown in fig. 9 and 10, the center of the limiting frame 24 is a connecting hole 2401, the connecting hole 2401 is sleeved outside the dust inlet pipe 23 and fixedly connected with the dust inlet pipe 23, and meanwhile, the limiting frame 24 is attached to a limiting inclined plane 2101 of the rotary pipe 21. When the rotary pipe 21 rotates, the limiting frame 24 on the limiting inclined plane 2101 can be driven to rotate, so that the dust inlet pipe 23 also rotates by taking the axial line of the rotary pipe 21 as an axis, and the dust inlet 2301 forming the dust inlet pipe 23 horizontally rotates in 360 degrees in a circulating way relative to the frame 1, so that dust on the periphery of the omnibearing adsorption frame 1 is realized.
In addition, the rotary pipe 21 is fixedly provided with connecting pins 2105 on both sides of the limiting inclined plane 2101, and bearings 212 are respectively arranged on the two connecting pins 2105. Referring to fig. 9 and 10 again, the limiting frame 24 is an annular through groove in the first gear 26, the bearings 212 of the two connecting pins 2105 are respectively contacted with two sides of the inner side wall of the through groove, and in this structure, the two bearings 212 can play a role in limiting the limiting frame 24, so as to avoid the limiting frame 24 from deviating to the side edge of the limiting inclined plane 2101.

Referring again to fig. 13, the second gear 27 is an internal gear, and an inclined relief slope may be provided above the inner side of the second gear 27 in order to avoid the upper portion of the first gear 26 cutting into the second gear 27. When the rotary pipe 21 rotates to drive the limiting frame 24 to rotate, the first gear 26 is meshed with the second gear 27, so that when the limiting frame 24 and the dust inlet pipe 23 rotate around the ball joint 2302 of the dust inlet pipe 23, the dust inlet 2301 of the dust inlet pipe 23 can rotate up and down circularly relative to the frame 1 while the dust inlet pipe 23 rotates horizontally by 360 degrees relative to the frame 1, the passing range of the dust inlet 2301 is improved, the dust collection range is improved, and the dust raising suppression efficiency is improved. Further, the limiting inclined plane 2101 is fixed with a plurality of bullnose wheels 211, and the limiting frame 24 is attached to the bullnose wheels 211 to rotate, so that friction force generated when the limiting frame 24 is driven to rotate through the first gear 26 and the second gear 27 is reduced.
As shown in fig. 11 and 12, the rotating mechanism 2 further comprises a rotating seat 25 and a swinging motor, a rotating ring 11 is arranged above the frame 1, an annular step (not shown in the drawings) is arranged on the inner wall of the rotating ring 11, and the rotating seat 25 is embedded on the annular step to rotate. Referring to fig. 6 again, the upper and lower sections of the rotary tube 21 are an expanded section 2103 and a reduced section 2104 with a relatively reduced diameter, wherein the reduced section 2104 passes through the rotary seat 25, so that the expanded section 2103 is clamped on the rotary seat 25 to form the axial fixation of the rotary tube 21 relative to the rotary seat 25, and the rotary tube 21 rotates relative to the rotary seat 25, and referring to fig. 14 and 15 again, a plurality of bull eyes 211 are distributed on the bottom surface of the expanded section 2103 to enable the rotary tube 21 to smoothly run relative to the rotary seat 25. The rotary motor 28 is fixed at the bottom of the rotary seat 25 to rotate the rotary tube 21 by the transmission of the third gear 29 and the fourth gear 210. This structure allows the rotary pipe 21, the transition pipe 22 and the dust inlet pipe 23 to rotate integrally with respect to the frame 1, thereby facilitating the dust inlet 2301 of the integral dust inlet pipe 23 to be in a prescribed upward or downward orientation at a prescribed position with respect to the frame 1. Meanwhile, the second gear 27 is also fixed on the rotating seat 25, so that the dust inlet pipe 23 and the limiting frame 24 rotate relative to the rotating seat 25 by taking the connecting hole 2401 of the limiting frame 24 as an axis while rotating relative to the rotating pipe 21.
Referring again to fig. 3, the swing motor 213 is fixed in the frame 1, and an output shaft of the swing motor 213 is fixedly connected to one end of the first link 214, one side of the rotating base 25 is provided with a connection lug 2501, the connection lug 2501 is pivoted to one end of the second link 215, and the other end of the first link 214 is pivoted to the other end of the second link 215. When the dust collector works, the swing motor 213 drives the first connecting rod 214 to rotate, so that the first connecting rod 214 rotates and simultaneously pulls the second connecting rod 215 to swing, thereby realizing the reciprocating rotation of the rotary seat 25 relative to the frame 1 in a certain angle range, and driving the dust inlet 2301 of the dust inlet pipe 23 to sweep in a large range outside the frame, further improving the dust absorption range and further improving the dust suppression effect.
In summary, in the structure of the present invention, the rotation of the rotary tube 21 drives the limiting frame 24 attached to the limiting inclined plane 2101 to rotate therewith, so as to drive the dust inlet tube 23 to rotate on the transition tube 22 relative to the frame 1 with the axis of the rotary tube 21 as the axis, thereby forming 360 ° circular rotation relative to the frame 1; meanwhile, in the process of rotating the limiting frame 24, the first gear 26 at the periphery of the limiting frame 24 rotates relative to the second gear 27, so that the dust inlet 2301 rotates up and down while the dust inlet pipe 23 is driven to horizontally rotate, and finally, the dust inlet 2301 forms two axial directions with the axial line of the rotary pipe 21 and the axial line of the connecting hole 2401 of the limiting frame and continuously rotates along the two axial directions.
The foregoing is merely illustrative of specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention by using the design concept shall fall within the scope of the present invention.
