Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 to 4, this embodiment provides a rolling brush mechanism for a road sweeper 10, which aims to solve the problem that the existing rolling brush is easy to sweep up dust and splash the dust when in operation, and at the same time, provides a rolling brush convenient to replace, so as to reduce the use cost, for this reason, the rolling brush mechanism for the road sweeper 10 provided by this embodiment includes a rolling brush support 1 and a rotating shaft 2 rotatably disposed in the rolling brush support 1, the rolling brush support 1 is also disposed in a semi-cylindrical shape as in the conventional art, and is hollow inside, and is provided with a curtain plate at the rear end (using the direction of the vehicle head as the front end) and at the two sides thereof for shielding dust, the rotating shaft 2 mainly functions as fixed bristles for driving the bristles to rotate to generate a centrifugal force, so as to achieve that the brush seedlings 3 are disposed on the rotating shaft 2, the connecting rods 4 for connecting with the road sweeper 10 are disposed at the two sides of the rolling brush support 1, be provided with hydraulic motor 5 on one of them connecting rod 4, adopt chain or belt or coupling joint transmission setting between hydraulic motor 5 and the pivot 2, in this embodiment, adopt chain drive, in order to avoid the dust to cause the influence and guarantee personnel's safety to the chain, in this embodiment, have protection box 6 at the chain dustcoat for realize the protection to drive mechanism and nearby personnel.

In order to solve the problem that the rolling brush throws away dust and flies upward (the rolling brush is arranged behind the road sweeper 10, because the rear end of the rolling brush support 1 is shielded by a curtain plate, for this reason, the rolling brush throws away the dust forward), for this reason, a dust cover 7 is further arranged on the rolling brush support 1, the dust cover 7 is arranged at one end of the rolling brush support 1 close to the road sweeper 10, because the rolling brush throws away not only dust, but also other garbage, if the dust cover 7 adopts a curtain plate structure, the garbage cannot be thrown into the feeding mechanism, and for this reason, the cross section of the dust cover 7 applied in the embodiment is in a circular arc shape. Like this, when guaranteeing to shelter from the dust, because the contact surface that the dust collided is the cambered surface, it can be in the same direction as smooth feed mechanism, and then reach dirt-proof purpose. Of course, other rounded curve shapes may be provided.

In order to reach the purpose that 3 changes of brush seedling, in this embodiment, brush seedling 3 can be dismantled and fix in pivot 2, be provided with slot 21 on specific saying so pivot 2, the lateral wall of slot 21 is the T style of calligraphy setting of invering, like this, arbitrary two adjacent lateral walls just can constitute slot 21, and arbitrary 3 adjacent lateral walls then can constitute 2 slot 21, the number that specific saying so slot 21 is the number of lateral wall subtracts one, and slot 21 is the even distribution of annular on pivot 2, like this, just can place brush seedling 3 at will, according to the condition of the inside, can insert more and brush seedling 3 or reduce placing of brush hair. The brush seedlings 3 are inserted into the slots 21.

Considering that the brush seedlings 3 arranged in the same row have different wear degrees and are integrally replaced after being damaged, a large amount of resources are wasted, and therefore, in the embodiment, a plurality of brush seedlings 3 are arranged in the slot 21. Therefore, the brush seedlings 3 in each row are formed by a plurality of brush seedlings 3, so that the brush seedlings are convenient to replace. In this embodiment, the length of each section of brush seedling 3 is about 10cm, considering that when the rolling brush rotates at a relatively high rotation speed, the brush seedlings 3 may not be fully distributed in the whole slot 21, and the brush seedlings on the whole rotating shaft 2 may be distributed spirally, so that, when the rolling brush rotates at a relatively high rotation speed, the cleaning surface formed by the rolling brush seedling is the same, and the brush seedlings 3 may move in an insertion manner along with the rotation, for this reason, a spring lock catch or pin structure may be added at the bottom of the brush seedlings 3 to achieve fixation, in this embodiment, the brush seedlings 3 are provided with the fixing pins 31, and fixed by using a pin type structural design, it should be noted that the brush seedlings 3 provided by this embodiment have two parts, namely, a brush seedling base and a brush seedling 3, wherein the brush seedling base is made of a resin material, so that the fixing pins 31 have a certain elasticity, and are convenient to clamp the fixing pins 31 to prevent the fixing pins 31 from moving, when the replacement is performed, the fixing pin 31 is pulled out.

In consideration of the smoothness of the road surface and the abrasion condition of the rolling brush, in the embodiment, the connecting rod 4 is arranged on the road sweeper 10 in a shaft coupling mode, the adjusting oil cylinder 8 is arranged on the connecting rod 4, the piston rod of the adjusting oil cylinder 8 is hinged to the middle of the connecting rod 4, the other end of the adjusting oil cylinder 8 is hinged to the road sweeper 10, therefore, the adjusting oil cylinder 8 can control the lifting of the whole rolling brush mechanism, the abrasion and the shortening of the brush seedling 3 of the rolling brush mechanism in the using process are considered, and for this reason, the height adjusting device 9 is arranged at one end, far away from the road sweeper 10, of the connecting rod 4. The height adjusting device 9 comprises a chain 91 fixed on the road sweeper 10 and a basket nut 92 fixed on the connecting rod 4, and the chain 91 and the basket nut 92 are connected. In this way, the height adjustment of the entire roller brush holder 1 can be achieved without the adjustment cylinder 8 being moved. And the stability of the fixation of the whole rolling brush mechanism is ensured by utilizing the connection of three points.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
