Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a road cleaning brush used in a road cleaning vehicle.

[Prior Art] A Gatsuta brush used in a conventional road sweeping vehicle is a single Gatsuta brush 11 with a conical open hem.
As shown in FIG. 2, it is attached to the front of the work vehicle 12 and rotates around a vertical axis while contacting the road surface under the control of an operator riding on a drive vehicle 13 to clean the road surface. Therefore, as shown in FIG. 3, when the road shoulder 14 has two levels, for example, in the first cleaning operation, the rattle brush 11 is raised higher than the road surface to clean the higher level of the road shoulder 14 first. Then, in the second operation, the rattling brush 11 must be lowered to clean the lower step, and the same road must be traveled twice and the cleaning operation performed twice. This resulted in a disadvantage that the work took a long time and was inefficient.

[Problems to be solved by the invention] This invention can solve problems even when the road shoulder is two steps.
To provide a road cleaning brush that can clean the road shoulder in one operation.

[Means for Solving the Problem] An upper brush and a lower brush are mounted on vertical mounting shafts connected at one end to a drive device, and the relative positions of both brushes are adjustable.

[Operation] By adjusting the vertical relative positions of the upper and lower brushes to match the level difference on the road shoulder, the upper brush cleans the upper part of the road shoulder, and at the same time, the lower brush cleans the lower road surface.

[Example] Fig. 1 is a partial cross-sectional view of a two-stage road cleaning brush according to the present invention. An upper brush A is attached to the upper part of a mounting shaft 3 whose one end is connected to a hydraulic motor 10 serving as a drive device to rotate, and a lower brush B is attached to the lower part thereof. The upper brush A consists of a mounting plate 1 to which brush bristles are attached, a fixing plate 5 to which the bristles are fixed, and two lock nuts 4a and 4b which fix these to a threaded mounting shaft 3 from above and below. Lower brush B has the same structure, including brush bristle mounting plate 6, brush bristle 7, and brush bristle 7.
fixing plate 8 and lock nuts 9a, 9 for fixing
Consists of b. Note that the width of the hem of the conical bristles 2 of the upper brush A, that is, the radius, is larger than that of the lower brush B, and therefore the radius of the bristle mounting plate 1 and the fixing plate 5 is also larger than that of the lower brush B. Brush B
The radius is larger than the radius of the brush bristle mounting plate 6 and the fixing plate 8. Relative position of upper brush A and lower brush B,
That is, to change the interval, for example, lower brush B
Loosen the upper and lower nuts 9a and 9b, move the brush bristle mounting plate 6 and the fixed 8 up and down along the mounting shaft 3 to desired positions, and fix them to the mounting shaft 3 with the upper and lower nuts 9a and 9b.

Therefore, when cleaning the road shoulder 14 which is divided into two stages as shown in FIG. ), if both of these brushes are driven at the same time, the upper brush A will move to the road shoulder 1.
The lower brush B cleans dirt, dust, fallen leaves, etc. on the upper stage of the road shoulder 14, and the lower brush B simultaneously cleans the earth, sand, trash, fallen leaves, etc. on the lower stage of the road shoulder 14.

[Effect of the invention] An upper brush and a lower brush are attached to a vertical mounting shaft whose one end is connected to a drive device, and the relative positions of both brushes can be adjusted according to the level difference on the road shoulder to be cleaned. Therefore, the two-tiered roadside can be cleaned simultaneously in one operation using the upper and lower brushes, reducing cleaning time and improving work efficiency.
