[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] A dust collection mechanism of a sweeper, comprising a dust collection head 1, a conveying hose 2 is installed on the top of the dust collection head 1, a bracket 4 is installed on one side of the dust collection head 1 through a connecting rod 3, two driving plates 5 that can move away from or approach each other are arranged on one side of the dust collection head 1, brushes 6 are arranged at the bottom of the two driving plates 5, and the two driving plates 5 are movably arranged at the bottom of the bracket 4 through a reciprocating mechanism;

[0027] The reciprocating mechanism includes a slide 7, a traction rod 8, a guide rod 9, an elastic member and a driving member. The slide 7 is arranged on the surface of the bracket 4. The traction rod 8 is vertically fixed to the top surface of the driving plate 5 and is slidably arranged in the slide 7. The guide rod 9 is horizontally fixed to the inner wall of the slide 7. The traction rod 8 is slidably arranged on the guide rod 9 and cooperates with the slide 7 through the elastic member. The driving member is movably arranged on the bracket 4 through the driving mechanism and cooperates with the traction rod 8. The elastic member is a spring 10 fixed to the inner wall of the slide 7 and the surface of the traction rod 8. The spring 10 is sleeved on the surface of the guide rod 9. The driving member is a trapezoidal plate 11 and a square plate 12. The square plate 12 is fixed to one side of the trapezoidal plate 11, and the guide rod 9 is in conflict with the side of the square plate 12.

[0028] See also Figure 1 and 2 The reciprocating mechanism can simultaneously drive the two driving plates 5 to approach or move away from each other, so that the driving plate 5 drives the brush 6 to move synchronously. Since the bottom of the brush 6 is in contact with the ground, the brush 6 can brush the road surface during the continuous reciprocating movement. Moreover, since the bristles of the brush 6 are elastic, the initial height of the brush 6 can be set relatively low. At this time, the bristles of the brush 6 will become bent due to extrusion, but when the bristles go deep into the gaps in the road surface, the bent bristles can easily enter the gaps to clean the dust.

[0029] The driving mechanism includes a limit rod 13, a sleeve 14, a connecting arm 15 and a cylinder 16. The limit rod 13 is fixed between the dust collector head 1 and the bracket 4. The sleeve 14 is movably arranged on the limit rod 13. The cylinder 16 is installed on the side of the dust collector head 1. One end of the connecting arm 15 is fixed to the bottom of the sleeve 14, and the other end of the connecting arm 15 is fixed to the output end of the cylinder 16.

[0030] See also Figure 3 and 4 When the output end of the cylinder 16 is extended to the maximum stroke, the sleeve 14 can be driven to move to the farthest end on the limit rod 13 through the connecting arm 15. At this time, the sleeve 14 drives the trapezoidal plate 11 to move synchronously, which makes the inclined part of the side of the trapezoidal plate 11 constantly approach the traction rod 8 and gradually squeeze the traction rod 8. After the traction rod 8 is squeezed in the X-axis direction of the trapezoidal plate 11, since the traction rod 8 cannot move in the X-axis direction inside the slide groove 7, the squeezing force of this part will drive the traction rod 8 to move in the Y-axis direction inside the slide groove 7, thereby realizing the two driving plates 5 to move away from each other, and at this time, the traction rod 8 will compress the spring 10 inside the slide groove 7. When the trapezoidal plate 11 is reset, the spring 10 will drive the traction rod 8 to reset through its own elastic force, so that the traction rod 8 drives the driving plate 5 to reset. At this time, the two driving plates 5 are close to each other, and the control cylinder 16 is continuously extended and reset, which can make the two driving plates 5 continuously reciprocate in the Y-axis direction, so that the road surface can be brushed by the brush 6.

[0031] Two rollers 20 are fixed to the other end of the vacuum cleaner head 1 , and the bottoms of the rollers 20 are in contact with the ground. A pipe 21 is also fixed to the other side of the vacuum cleaner head 1 , and five nozzles 22 are arranged at the bottom of the pipe 21 .

[0032] See also Figure 2 The setting of the roller 20 can assist the vacuum cleaner head 1 to move when the vacuum cleaner head 1 moves with the vehicle body, and can also play a certain supporting role for the vacuum cleaner head 1.

[0033] Embodiment 2:

[0034] In the above scheme, since the driving plate 5 needs to reciprocate in the horizontal direction, and the traction rod 8 that provides power to the driving plate 5 is arranged at one end of the driving plate 5, the other end of the driving plate 5 will be slightly tilted due to the unevenness in the hand, causing the cleaning effect to be affected. Therefore, in this embodiment, a guide structure is arranged between the driving plate 5 and the dust collector head 1, and the guide structure includes a track 17, a slot 18 and a support arm 19. The support arm 19 is welded to one end of the driving plate 5, the track 17 is arranged on the surface of the dust collector head 1, the slot 18 is arranged on the surface of the support arm 19 and cooperates with the track 17, and the support arm 19 is inclined. One side of the support arm 19 is in contact with the surface of the dust collector head 1.

[0035] See also Figure 1 and 5 When the driving plate 5 moves horizontally, the driving plate 5 can drive the supporting plate to move synchronously. During the movement of the supporting plate, one end of the supporting plate will always move synchronously on the surface of the track 17 through the card slot 18. When the driving plate 5 moves to the maximum stroke in two different directions, the supporting arm 19 will not detach from the surface of the track 17, so that the driving plate 5 can be supported in the vertical direction to prevent the driving plate 5 from tilting in the vertical direction during the movement.

[0036] Working principle: When in use, the cylinder 16 is driven to perform reciprocating motion. The cylinder 16 can drive the trapezoidal plate 11 to reciprocate on the surface of the limit rod 13 through the connecting arm 15 and the sliding sleeve 14. The inclined side of the trapezoidal plate 11 can squeeze the two traction rods 8 at the same time, so that the traction rod 8 moves axially along the guide rod 9 inside the slide groove 7. At this time, the two driving plates 5 are away from each other, and the traction rod 8 will compress the spring 10 inside the slide groove 7. When the trapezoidal plate 11 is reset, the spring 10 will drive the traction rod 8 to reset through its own elastic force, so that the traction rod 8 drives the driving plate 5 to reset. At this time, the two driving plates 5 are close to each other. Through the above process, the reciprocating motion of the brush 6 can be realized, so as to clean the road surface.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
