[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 6 As shown, a roller brush structure for a road snow removal vehicle includes a bracket 1, a brush roller unit and a drive unit; the drive unit includes a hydraulic motor 2 and a drive shaft 4; the drive shaft 4 is rotatably mounted on the bracket 1; the hydraulic motor 2 is fixed to one side of the bracket 1 and is in transmission connection with the drive shaft 4; the brush roller unit includes a plurality of brush roller assemblies 3 mounted on the drive shaft 4, the plurality of brush roller assemblies 3 are arranged in an array at equal intervals along the axial direction of the drive shaft 4, the hydraulic motor 2 drives the drive shaft 4 to rotate, and the snow on the road surface is cleaned by the rotational movement of the brush roller assembly 3 on the drive shaft 4; the brush roller assembly 3 includes a collar 39, a stopper 33 and a plurality of brush head assemblies ; The collar 39 is sleeved and fixed on the drive shaft 4; the brush head assembly is arranged on the outer side of the collar 39, and multiple brush head assemblies are distributed in a circular array with the axis of the collar 39 as the center; the brush head assembly includes an arc seat 32, a brush 31, a connecting rod 36, a spring 310 and a connecting tube 35; one end of the connecting tube 35 is fixed to the outer side of the collar 39; the axis of the connecting tube 35 is arranged perpendicular to the axis of the collar 39; one end of the connecting rod 36 is slidably placed in the connecting tube 35, and the connecting rod 36 can move along the axis direction of the connecting tube 35 in the connecting tube 35, and the other end of the connecting rod 36 extends to the outside of the connecting tube 35 and is connected to the arc seat 32 is fixedly connected to drive the arc seat 32 to move synchronously; the spring 310 is placed in the connecting tube 35, one end of which is fixedly connected to the connecting tube 35, and the other end is fixedly connected to the connecting rod 36, and is used to pull the connecting rod 36 into the connecting tube 35 to prevent the connecting rod 36 from falling out of the connecting tube 35; the brush 31 is fixed on the side of the arc seat 32 away from the connecting rod 36; a guide plate 34 is fixedly provided on the side of the arc seat 32 close to the connecting rod 36, and the height of the guide plate 34 gradually increases from both sides to the center; the limiter 33 is horizontally placed on one side of the arc seat 32; one end of the limiter 33 is fixedly connected to the bracket 1, and the other end is provided with a roller 3 11. The roller 311 is in rolling contact with the guide plate 34. When the driving shaft 4 drives the roller brush assembly to rotate, when the arc seat 32 rotates to the roller 311 of the limiter 33 and contacts the guide plate 34, the roller 311 rolls along the contour curve of the guide plate 34. When the roller 311 moves from one side of the guide plate 34 to the center, the roller 311 applies a thrust to the guide plate 34 in the direction away from the axis of the driving shaft 4, so that the arc seat 32 moves in the direction away from the driving shaft 4. Multiple brush roller assemblies 3 contact the limiter 33 in turn, so that the roller brush assembly reciprocates along the axis of the connecting tube 35 while rotating, so that the snow on the brush 31 is shaken off.

[0022] Furthermore, two guide plates 34 are provided on the arc seat 32 and are symmetrically arranged on both sides of the connecting rod 36; two limiters 33 are provided corresponding to the guide plates 34, so that the forces on both sides of the arc seat 32 are balanced and the service life is extended.

[0023] Furthermore, the brush head assembly also includes a guide rod 37 and a guide cylinder 38; one end of the guide cylinder 38 is fixedly connected to the arc seat 32; the axis of the guide cylinder 38 is arranged parallel to the axis of the connecting cylinder 35; one end of the guide rod 37 is slidably placed in the guide cylinder 38, and the other end extends to the outside of the guide cylinder 38 and is fixedly connected to the arc seat 32, and the guide rod 37 moves synchronously with the arc seat 32. Through the arrangement of the guide rod 37 and the guide cylinder 38, the connecting rod 36 is prevented from rotating around the axis of the connecting rod 36 in the connecting cylinder 35.

[0024] Furthermore, a paddle 5 is fixedly provided inside the bracket 1; the paddle 5 extends along the axial direction of the driving shaft 4, and one end of the brush 31 is in frictional contact with the paddle 5. When the connecting rod 36 extends to the outside of the connecting tube 35, the snow on the brush 31 is scraped off by the paddle 5, thereby improving the snow cleaning effect on the brush 31.

[0025] Furthermore, two paddles are provided; the limiter 33 is arranged on the area of ​​the bracket 1 between the two paddles, and scrapes the upper and lower parts of the brush 31 at the same time, so that the snow on the brush 31 can be cleaned more cleanly.

[0026] When in use, after the hydraulic motor 2 is started, the brush roller unit is driven to rotate through the drive shaft 4 to clean the snow on the road surface. When the arc seat 32 of the brush roller assembly 3 rotates to the position of the limiter 33, the contact between the roller 311 of the limiter 33 and the guide plate 34 causes the arc seat 32 to move in a direction away from the drive shaft 4. When the guide plate 34 is out of contact with the roller 311, the spring 310 drives the arc seat 32 to reset, so that the brush 31 on the arc seat 32 is vibrated by the reciprocating motion during the rotation, so that the snow on the brush 31 is shaken off, thereby improving the working effect.
