Abstract

PURPOSE: To enable an electric cleaner for cleaning with a rotating brush a surface on which the electric cleaner moves to control ground pressure easily, by having a hopper in the rear surface of the front of the electric cleaner, which hopper is capable of turning on a vertically movable rotation shaft. CONSTITUTION: An electric cleaner 1 comprises in the lower part of a body 2 thereof a main brush 6 for cleaning a surface on which the electric cleaner moves and a hopper 7 for containing dust which has been swept up with the main brush 6. The hopper 7 is positioned in front of the main brush 6. The electric cleaner 1 further comprises a rotatable side brush supporting mechanism 8 in the outer diagonal front of the car 2 and bumpers 9 and 10 in the front and rear of the body 2. In this case, the happen 7 is attached to the rear surface of the front of the body 2, such that the hopper 7 is capable of turning on a vertically movable rotation shaft. Illustratively stated, the hopper 7 is supported, such that the hopper 7 is capable of turning on a shaft 19 in the vertical directions and an attachment 17 for supporting the shaft 19 is capable of vertically moving along a long hole 20, so that ground pressure is easily controlled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts a hopper on a vehicle body in such a manner that it can be tilted about a rotary shaft that can move in the vertical direction to facilitate adjustment of ground pressure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a structure in which a hopper 7 is connected to a front lower surface of a vehicle body 2 by a parallel link mechanism 27, and another structure is shown in FIG. So that the hopper 7 is rotatably supported on the vehicle body 2 by inserting the pin 19 into the hole 22 formed in the lower front surface of the vehicle body 2 and the hole 24 formed in the mounting piece 25 of the hopper 7. There is.

[0003]

In the former configuration of the related art, there is a problem that if the adjustment range is large, the link becomes long and a large space is required.
On the other hand, in the latter configuration, there is a problem that it is difficult to adjust the orientation of the cleaning device at the time of grounding. 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 traveling road surface with a rotating brush which is arranged at a lower portion of the vehicle body and rotates in a direction perpendicular to the traveling road surface. The above-described problem is solved by a configuration in which a hopper mounted so as to be tiltable about a movable rotation shaft is used.

1 is a side view of an automatic cleaner used in the present invention, and FIG. 2 is a plan view of the automatic cleaner used in the present invention. Where, 1 is an automatic cleaner, 2 is a vehicle body of the automatic cleaner 1, 3 is a vehicle body cover that covers the upper portion of the vehicle body 2, 4 is a drive wheel attached to the lower center of the vehicle body of the automatic cleaner 1, and 5 is automatic The casters mounted on the rear part of the vehicle body of the vacuum cleaner 1, 6 are arranged at the lower part of the vehicle body of the automatic cleaner 1, rotate in the direction perpendicular to the traveling road surface and clean the traveling road surface, 7 is the automatic cleaning device 1 Is a hopper that is detachably attached to the vehicle body 2 in the lower part of the vehicle body and in front of the main brush 6, and collects dust blown up by the rotation operation of the main brush 6, and 8 is an oblique front side of the vehicle body 2 of the automatic cleaner 1. Side brush holding mechanism rotatably mounted on the outside, Front bumper which is fixed to the front of the vehicle body 2 of the automatic cleaning device 1, 10 is a vehicle body 2 of the automatic cleaner 1
Rear bumper fixed to the rear of the vehicle, 11 is the body cover 3
An operation panel mounted on the vehicle body 12, a first dust collection box 12 housed in the vehicle body 2, a second dust collection box 13 housed in the vehicle body 2 and arranged at a rear stage of the first dust collection box 12, Reference numeral 14 is a control unit housed in the vehicle body 2, 15 is a vacuum hose connecting the hopper 7 and the first dust collecting box 12, and 16 is a battery for supplying energy for driving the automatic cleaner 1.

Reference numeral 17 is a mounting member having a house-like shape,
A pair of elongated holes 20 are formed in the vertical direction, and a circular hole 22 is formed in a pointed portion 21 having a house-like shape. The mounting member 17 is fixed to the front lower surface of the vehicle body 2 with a bolt 23. When the bolt 23 is loosened and the mounting member 17 is moved in the vertical direction, the mounting member 17 is moved in the vertical direction of the vehicle body 2 along the elongated hole 20. it can.

Reference numeral 18 denotes a hopper mounting member, which has a mountain-like shape, and a circular hole 24 is formed in a pointed portion 25 of the mountain-shaped shape, leaving a central portion on the vehicle body mounting surface side of the hopper 7. The hopper mounting member 18 is formed.

The mounting member 17 mounted on the vehicle body 2 and the hopper mounting member 18 formed on the hopper 7 have a shaft 19 inserted into a circular hole of a pointed portion, and the hopper 7 is mounted on the shaft of the vehicle body 2. The mounting member 17 can be vertically moved vertically with respect to the vehicle body 2 while being vertically rotated about 19. 26 is hopper 7
It is a caster that supports.

[0009]

As described above, the present invention includes the hopper mounted on the lower surface of the front of the vehicle body so as to be tiltable about the vertically movable rotary shaft, that is, the mounting member mounted on the vehicle body 2. 17 and the hopper mounting member 18 formed on the hopper 7, the shaft 19 is inserted into the circular holes of the pointed parts, and the hopper 7 is mounted on the shaft 1 with respect to the vehicle body 2.
Since the mounting member 17 can be vertically moved vertically with respect to the vehicle body 2 while rotating about 9 as a center, the ground pressure can be easily adjusted with a simple structure. You can also adjust the orientation of the cleaning device when it touches the ground.
