Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side brush holding mechanism projecting to the outside of a bumper, which is tiltably attached to the vehicle body to improve the cleaning ability of the side brush.

[0002]

2. Description of the Related Art Conventionally, a side brush is mounted so as to project obliquely outward from the front of a vehicle body, and the rotation shaft of the side brush is fixed at a predetermined angle. There is a configuration in which the shaft can be moved in the longitudinal direction and the lateral direction of the vehicle body width direction.

[0003]

In the former configuration of the related art, since the rotating shaft of the side brush is fixed at a predetermined angle and the angle cannot be adjusted, the uneven wear of the brush causes There is a problem that the grounding part 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 it is not decided well, the desired ground contact position cannot be obtained, and there is the problem that considerable skill and experience are required for adjustment. The present invention has been devised to solve the above problems.

[0004]

SUMMARY OF THE INVENTION The present invention is an automatic cleaner for cleaning a traveling road surface with a main brush which is arranged in a lower portion of a vehicle body and rotates in a direction perpendicular to the traveling road surface. The above problem is solved by a configuration in which a side brush holding mechanism that is provided and projects to the outside of one of the bumpers is tiltably attached to the vehicle body.

[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.

A side brush mounting mechanism rotatably mounted on the outer front side of the vehicle body 2 of 1, a front bumper 9 fixed to the front of the vehicle body 2 of the automatic cleaner 1, and a rear side of the vehicle body 2 of the automatic cleaner 1. A rear bumper fixed to the vehicle body; an operation panel 11 attached to the vehicle body cover 3;
Is a first dust collection box stored in the vehicle body 2, 13 is stored in the vehicle body 2 and is a second dust collection box arranged at the rear stage of the first dust collection box 12, and 14 is stored in the vehicle body 2. The control unit, 15 is a vacuum hose that connects the hopper 7 and the first dust collecting box 12, and 16 is a battery that supplies 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. FIG. 1 is a side view showing a first mounting bracket 18 having an L-shape and fixed to a vehicle body 2 by 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, the first adjustment bolt 24 and the second adjustment bolt 25, which are movable in the horizontal direction, are screwed into the L-shaped horizontal portion 18B through the elongated holes 26.

A second mounting bracket 19 has an L-shape similar to the first mounting bracket 18. The L-shaped horizontal portion 19B is located in front of the vehicle body, and the corner member 27 is fixed to the end of the upper surface of the horizontal portion. A flat plate 28 having a predetermined thickness is fixed to each 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. Further, a hollow space is provided in front of the vertical wall of the L-shaped member 29. The tubular body 31 is fixed to be horizontally long.

As shown in FIG. 5, the second mounting bracket 19 and the first mounting bracket 18 are the corner member 27 fixed to the end of the horizontal portion 19B of the second mounting bracket 19 and the first mounting bracket. A pair of eighteen members 23 and 18 are rotatably supported by pins 32.

As shown in FIG. 5, a first adjusting bolt 24 is fitted 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 used for the first adjusting bolt 24. When 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 by sliding the bolt 24 along the elongated hole 26, the horizontal portion of the second mounting bracket 19 is pushed up. The side brush 22 separates from the ground. The horizontal portion of the first mounting bracket 18 other than the flat plate can be pushed downward.
The second adjusting bolt 25 at the tip of 8B
The tilt angle of the mounting bracket 19 is adjusted.

Reference numeral 20 denotes a third mounting bracket, which is a member having a U-shaped cross section having a long lower side 41 as shown in FIG. 6, and the lower side 41 is L above the front wall of the vertical portion of the second mounting bracket 19. It is inserted into a space formed by the letter-shaped member 29 and the lower flat plate 30, and is rotatably supported by a pin (not shown). A brush rotation motor 33 for rotating a brush is attached to the upper side 40, and a lower side. 41 and the upper side 40 are fixed by a cylindrical member 20A, and a wedge-shaped member 42 is fixed on 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 the shaft of the brush mounting member 34 for fixing the brush 22. 34A and the rotation shaft 33A of the brush rotation motor 33 are connected via a key, and a bearing 35 is inserted between the outer periphery of the shaft 34A and the inner periphery of the cylindrical member 20A with the brush mounting member 34.

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

As shown in FIG. 3, a pair of protrusions 39 are fixed or attached to the rear end of the lower side of the third mounting bracket 20 so as to be fixed or 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 to stop the traveling of the automatic cleaner 1.

[0016]

As described above, according to the present invention, a bolt is screwed into an elongated hole formed in the L-shaped horizontal portion of the first mounting bracket, and the bolt is slid along the elongated hole. When sandwiched by 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 is pushed down except the flat plate. Since the side brush holding mechanism is tiltably attached to the side, even if the ground contact portion is reduced due to uneven wear of the brush, tilting the side brush holding mechanism can maintain a certain cleaning ability and clean. If not, you can raise the brush above the road to avoid damaging it. Further, in the above-described embodiment, the arm is pulled out from the inside of the vehicle body, so that it is possible to obtain an effect such that the arm easily fits within the vehicle width.
