In one embodiment, the driving means 61 may be, but is not limited to, an electric cylinder.

Further, both ends of the left roll brush 10 and both ends of the right roll brush 20 are respectively connected to the first swing assembly 53 and the second swing assembly 54. The concrete implementation is as follows: the two ends of the left rolling brush 10 are respectively arranged on the connection of the first cross rod 531 and the second swing rod 533 and the connection of the second cross rod 541 and the fourth swing rod 543, and the two ends of the right rolling brush 20 are respectively arranged on the connection of the first cross rod 531 and the first swing rod 532 and the connection of the second cross rod 541 and the third swing rod 542.

Further, the second swing assembly 54 further includes a pneumatic spring 544, and two ends of the pneumatic spring 544 are respectively connected to the bracket 30 and the third swing link 542.

It should be noted that, the working process of the rotation driving assembly 60 to drive the first swinging assembly 53 and the second swinging assembly 54 to move to realize the rotation of the baffle 40 is as follows: when the driving device 61 drives the push rod 62 to stretch and retract relative to the driving device 61, the two ends of the first cross rod 531 connected with the push rod 62 are driven to move along the pair of inclined grooves 311 to realize downward movement of the first cross rod 531, the downward movement of the first cross rod 531 drives one end of the first swing rod 532 to rotate around the first shaft 511 and the other end of the first swing rod 532 to swing along the inclined groove 311 along with the first cross rod 531, and the downward movement of the second cross rod 541 also drives one end of the second swing rod 533 to rotate around the second shaft 512 and the first end of the second swing rod 533 to swing along with the first cross rod 531 along with the inclined groove 311; since the two ends of the left rolling brush 10 and the right rolling brush 20 are respectively connected to the first swinging component 53 and the second swinging component 54, under the action of the movement of each component of the first swinging component 53, the movement force is transmitted to the second swinging component 54 through the left rolling brush 10 and the right rolling brush 20, and meanwhile, the pneumatic spring 544 also gives the third swinging rod 542 a pushing action towards the ground, so that: one end of the third swing link 542 rotates around the first shaft 511 and the other end swings along the inclined groove 311, and one end of the fourth swing link 543 rotates around the second shaft 512 and the other end swings along the inclined groove 311, and the second cross bar 541 is moved downward and both ends of the second cross bar 541 to which the third swing link 542 and the fourth swing link 543 are connected move along the pair of inclined grooves 311, respectively; the action of the fourth swing rod 543 and the second cross bar 541 drives the driving plate 52 to move, so as to drive the baffle 40 fixedly connected with the driving plate 52 to rotate around a rotation shaft arranged on the bracket 30, so as to realize the aforementioned inclined arrangement of the baffle 40.

Further, the rolling brush cleaning structure 100 further includes two cleaning driving assemblies, and the two cleaning driving assemblies are respectively connected to the left rolling brush 10 and the right rolling brush 20, and are used for driving the left rolling brush 10 and the right rolling brush 20 to reversely rotate so as to throw the ground garbage up to the garbage box.

Specifically, each cleaning driving assembly comprises a motor, a driving wheel connected with the motor, a driven wheel and a synchronous belt in transmission connection with the driving wheel and the driven wheel, wherein the driven wheel is arranged on the left rolling brush 10 or the right rolling brush 20. The motor drives the driving wheel to rotate so as to drive the synchronous belt to turn round, and further drives the driven wheel to rotate, and the driven wheel rotates to drive the rolling brush on the driven wheel to rotate so as to clean.

In the brush cleaning structure 100, the baffle 40 is arranged in an area surrounded by the bracket 30, the left roller brush 10 and the right roller brush 20, the connecting rod assembly 50 arranged on the bracket 30 is connected with the rotation driving assembly 60 and the baffle 40, the driving assembly drives the baffle 40 to rotate through the connecting rod assembly 50 so as to enable the baffle 40 to be obliquely arranged between the left roller brush 10 and the right roller brush 20, and the obliquely arranged baffle 40 is used for promoting garbage which is taken up by the roller brush rotation and passes through the space between the left roller brush 10 and the right roller brush 20 to move towards the left roller brush 10. Therefore, the possibility that the garbage carried by the left rolling brush 10 rotates and falls back to the left rolling brush 10 and continues to rotate along with the left rolling brush 10 can be effectively reduced, the garbage carried by the left rolling brush 10 faces to the right rolling brush 20 as much as possible, and the garbage is rotated and thrown into the garbage box at one side of the right rolling brush 20 through the right rolling brush 20, so that the cleaning effect is effectively improved.

It should be noted that, since both ends of the left rolling brush 10 and the right rolling brush 20 are connected to the first cross bar 531 and the second cross bar 541, when the first cross bar 531 and the second cross bar 541 move downward to a certain position, the left rolling brush 10 and the right rolling brush 20 also press downward toward the ground, so that the left rolling brush 10 and the right rolling brush 20 can be cleaned as close to the ground as possible. Moreover, as the left and right rolling brushes 10 and 20 continue to clean, the brushes of the rolling brushes become shorter, and the shortened brushes may not be able to clean close to the ground, both ends of the left and right rolling brushes 10 and 20 are disposed on the first and second cross bars 531 and 541, and when the first and second cross bars 531 and 541 move downward, the left and right rolling brushes 10 and 20 also move downward toward the ground. Therefore, the structure of the baffle 40 can simultaneously realize the rotation of the baffle 40 and the downward movement of the left and right rolling brushes 10 and 20, so that the shortened rolling brushes can be cleaned by sticking and the garbage carried by the rotation of the left rolling brush 10 is blocked by the baffle 40 and falls back onto the left rolling brush 10, thereby improving the cleaning effect.

The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
