BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sweeper equipped with a side brush.

[0002]

2. Description of the Related Art Conventionally, a road cleaning vehicle provided with a side brush has
As shown in FIG. 2, the rotation axis of the side brush 4 is perpendicular to the floor including the longitudinal center line XX of the frame of the vehicle body.
9b and a support 39 having a pivot 39a parallel to the center line XX has a bracket 39c at one end of the parallel pivot 39a, and the bracket 39c holds a side brush. The one end of the parallel arm 30 is pivotally mounted to hold the side brush so as to be able to swing up and down, and the side brush is pivotally mounted to the vehicle body by a vertical pivot 39b so that the side brush can be rotated in the horizontal direction. keeping. Since the longitudinal center line XX of the vehicle body is inclined forward and downward, the rotation axis of the side brush 4 is also inclined forward, and the parallel axis 39a of the support 39 is rotated by an appropriate angle by visual measurement. The rotation axis of the side brush 4 is inclined so that a tilt angle suitable for the inclination of the road surface is given to the side brush 4, and the side brush 4 is adjusted so as to form an ideal ground contact shape with the road surface as shown in FIG. Had become.

[0003]

Since the above-mentioned conventional road cleaning truck is not provided with a display device for displaying the inclination of the rotation axis of the side brush 4, the inclination of the rotation axis of the side brush 4 is first set. Since there is no reference for the given inclination angle a ° when giving it, since a rough inclination angle is given by visual measurement, an ideal grounding shape of the side brush with respect to the ground (FIG. 4)
, And thus leaving a postcard (FIG. 5),
There is a disadvantage that the tilt angle must be adjusted many times.

An object of the present invention is to provide a tilt angle display device which can easily set the tilt angle a ° given to the rotation axis of the side brush to an optimum angle based on experience.

[0005]

SUMMARY OF THE INVENTION A side brush inclination angle display device for a road cleaning vehicle according to the present invention is provided on a side portion of a vehicle body, and has a pivot axis perpendicular to a floor including a longitudinal center line of a frame of the vehicle body. A support having a pivot parallel to the center line, having a bracket at one end of the parallel pivot;
The bracket pivotally connects one end of two parallel arms holding a side brush to hold the side brush so as to be able to swing up and down, and is pivotally attached to the vehicle body by the vertical pivot. The brush can be rotated in the horizontal direction, and the side brush extends to the side of the vehicle body with the rotation of the brush itself, and moves forward. A pointer provided at right angles to the center line of the pivot, and a scale plate fixed to the support for reading an angle displayed by the pointer.

[0006]

Since the side brush is held by a pivot parallel to the floor of the vehicle body to be fitted with the support, the tilt angle of the rotation axis of the side brush can be set by rotating the pivot. . The angle of inclination can be directly known by the scale shown on the scale plate of the pointer provided at the end of the pivot, and can be visually recognized by the rearview mirror of the vehicle body even during driving.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the tilt angle display device 5 and the side brush 4 of the present invention.

A bracket 8 fixed to a vehicle body (not shown)
However, the support body 9 is horizontally rotatably supported by a vertical pivot 9b on the floor including the longitudinal center line XX of the body frame. A bracket 9c is provided at one end of a parallel pivot 9a penetrating the support 9 in parallel with the floor surface, and two parallel arms 10 pivotally attached to the bracket swing the side brush 4 up and down. Holding as possible. Therefore, if the parallel direction pivot 9a is rotated around its center line YY, the angle of rotation is perpendicular to the floor Z including the longitudinal centerline XX of the body frame of the rotation axis of the side brush 4 of the body frame. The inclination angle a ° with respect to −Z is shown. At the other end of the parallel direction pivot 9a, an indicator needle 5a is fixed at a right angle to the center line Y-Y.
Is displayed, the inclination angle a ° of the rotation axis of the side brush 4 can be known. By setting the dimensions of the indicator hand 5a and the scale plate 5b to appropriate sizes, the operator can visually recognize the indicated angle even during driving with the rearview mirror in the driver's seat.

[0009]

As described above, according to the present invention, the pointer for indicating the inclination of the side brush is provided at the end of the pivot for holding the side brush with respect to the vehicle body, and the scale plate is provided for the support for holding the pivot. Since the inclination of the rotation axis of the side brush is read directly by the scale plate, the inclination angle of the side brush can be set to a desired angle, so that there is an effect that the ground shape of the side brush with respect to the road surface can always be ideally set. Further, since the inclination angle of the side brush can be visually recognized from the driver's seat, it is possible to easily determine whether the set inclination angle of the side brush is appropriate while observing the cleaning condition of the road surface, and thus there is an effect of improving work efficiency.
