DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a side brush holding mechanism protruding outside a bumper on a vehicle body so as to be tiltable to improve the cleaning ability of the side brush.

[0002]

2. Description of the Related Art Conventionally, a side brush is projected and mounted diagonally forward and outward of a vehicle body, and a rotation axis of the side brush is fixed at a predetermined angle. There is a configuration in which the shaft can be moved in the front-back and left-right directions in the vehicle body length direction and the vehicle body width direction.

[0003]

In the former configuration, the rotation axis of the side brush is fixed at a predetermined angle and cannot be adjusted, so that the brush is partially worn due to uneven wear of the brush. There is a problem that the grounding portion is reduced and cleaning cannot be performed. On the other hand, in the latter configuration, adjustment in the front-rear and left-right directions is possible, but the adjustment mechanism is complicated, and both adjustments are required. If not properly determined, a desired ground contact position cannot be obtained, and there is a problem that adjustment requires considerable skill and experience. The present invention has been devised to solve the above problems.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to an automatic cleaner for cleaning a running road surface with a main brush rotating in a direction perpendicular to the running road surface, the bumper being provided at a lower portion of the vehicle body. The above object has been achieved as a configuration in which a side brush holding mechanism protruding outside one of the bumpers is attached to the vehicle body so as to be tiltable.

[0005]

When the ground contact portion is reduced due to uneven wear of the brush, the side brush holding mechanism is tilted so as to cover the reduced portion.

Reference numeral 1 denotes a side brush mounting mechanism rotatably mounted on the oblique front outside of the vehicle body 2, 9 denotes a front bumper fixed in front of the vehicle body 2 of the automatic cleaner 1, and 10 denotes a rear side of the vehicle body 2 of the automatic cleaner 1. The rear bumper 11 is fixed to the operation panel 11 mounted on the vehicle body cover 3,
Is a first dust collection box accommodated in the vehicle body 2, 13 is a second dust collection box arranged in the rear of the first dust collection box 12, and 14 is accommodated in the vehicle body 2. A control unit, 15 is a vacuum hose connecting between the hopper 7 and the first dust collection box 12, and 16 is a battery for supplying energy for driving the automatic cleaner 1.

The side brush mounting mechanism, which is a feature of the present invention, will be described in detail with reference to FIGS. 3 to 6. FIG. 3 is a plan view showing the mounting relationship with the vehicle body 2, and FIG. In the side view shown, reference numeral 18 denotes a first mounting bracket, which has an L-shape, and is fixed to the vehicle body 2 at an L-shaped vertical portion 18A. Moreover, a pair of members 23 are fixed to the vertical portion 18A toward the front of the vehicle body 2 and a hole is formed in the center. On the other hand, a first adjustment bolt 24 and a second adjustment bolt 25 that can move in the horizontal direction are screwed into the L-shaped horizontal portion 18B with a long hole 26.

Reference numeral 19 denotes a second mounting bracket, which has an L-shape similar to the first mounting bracket 18, and an L-shaped horizontal portion 19B is located in front of the vehicle body, and a corner member 27 is fixed to an end of the upper surface of the horizontal portion. A flat plate 28 having a predetermined thickness is fixed to the lower surface.

On the other hand, an L-shaped member 29 is fixed to the upper portion of the front wall of the vertical portion 19A, and a flat plate 30 is fixed to the lower portion thereof at predetermined intervals. The cylindrical body 31 is fixed horizontally long.

As shown in FIG. 5, the second mounting bracket 19 and the first mounting bracket 18 are composed of a corner member 27 fixed to an end of a horizontal portion 19B of the second mounting bracket 19 and a first mounting bracket. A pair of members 18 are rotatably supported by pins 32.

As shown in FIG. 5, a first adjusting bolt 24 is inserted into an elongated hole 26 formed in the L-shaped horizontal portion 18B of the first mounting bracket 18, and the first adjusting bolt 24 is inserted therein. When the bolt 24 slides along the elongated hole 26 and the lower surface of the flat plate 30 having a predetermined thickness fixed to the lower surface of the horizontal portion of the second mounting bracket 19 is sandwiched, the horizontal portion of the second mounting bracket 19 is pushed up, The side brush 22 moves away from the ground. In the case other than the flat plate, the horizontal portion is pushed down, so that the horizontal portion 1 of the first mounting bracket 18 is
The tilt angle of the second mounting bracket 19 is adjusted by the second adjustment bolt 25 at the tip of 8B.

Reference numeral 20 denotes a third mounting bracket, as shown in FIG. 6, which is a member having a lower side 41 having a long U-shaped cross section. It is inserted into the space formed by the letter-shaped member 29 and the lower flat plate 30 and is rotatably supported by pins (not shown). A brush rotation motor 33 for rotating the brush is mounted on the upper side 40, and the lower side is 41 and the upper side 40 are fixed by a cylindrical member 20A, and a wedge-shaped member 42 is fixed to the outer periphery of the cylindrical member 20A.

As shown in FIG. 6, the cylindrical member of the third mounting bracket 20 serves to connect the brush rotating motor 33 and the brush 22, and a shaft of a brush mounting member 34 for fixing the brush 22. 34A and the rotating shaft 33A of the brush rotating motor 33 are connected via a key, and a bearing 35 is inserted between the outer periphery of the shaft 34A with the brush mounting member 34 and the inner periphery of the cylindrical member 20A.

As shown in FIG. 6, a spring 36 is provided in the hollow cylindrical body 31 fixed to the front of the vertical wall of the L-shaped member of the second mounting bracket 19 in a horizontally long manner, and the spring 36 is pressed. The rod 37 is inserted into the cylindrical body 31, a disk 38 is rotatably mounted on one end of the rod 37, the disk 38 is fitted into the wedge 39, and an external force applied to the side brush is a drag of the spring 36. If it is larger than that, the spring 36 is compressed, and the third bracket 20 rotates at a position supported by the pin.

As shown in FIG. 3, a pair of projections 39 are fixed to the rear end of the lower side of the third mounting bracket 20 or mounted so as to be adjustable in the length direction or the width direction.
When the third mounting bracket 20 rotates by a predetermined angle or more, one of the protrusions 39 comes into contact with the front bumper 9 and stops the traveling of the automatic cleaner 1.

According to the apparatus according to the above-described embodiment, a bolt is screwed into the long hole formed in the L-shaped horizontal portion of the first mounting bracket, and the bolt is slid along the long hole, When sandwiched between the lower surface of a flat plate having a predetermined thickness fixed to the lower surface of the horizontal portion of the second mounting bracket, the horizontal portion of the second mounting bracket is pushed up, and the horizontal portion of the other than the flat plate is pushed up. Since the side brush holding mechanism is installed to be tiltable, even if the ground contact area is reduced due to uneven wear of the brush, by tilting the side brush holding mechanism, it is possible to maintain a constant cleaning ability and perform cleaning. When not, the brush can be raised above the traveling road surface so as not to damage the brush.
