Abstract

Abstract: A dust on a smooth floor surface is only pushed forward by a brush provided in a cleaning car, and is hardly swept up by a brush to collect dust in a dust box. SOLUTION: In a cleaning car for rotating a helical brush 2 by a driving device 3 to sweep dust to a dust box 6 and collect dust, a shaft 9 is horizontally suspended at a rear portion of the truck 1 and a swinging rod 10 is provided at a protruding end of the shaft. And coaxially attach the base end of the connecting rod 11 that abuts the roller cam 14 provided at the eccentric position of the hub surface of the rear wheel to one of the swinging rod base ends, and scoop up between the leading ends of the swinging rods. The plate 13 was placed horizontally and in front of the spiral brush.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor sweeper, and more particularly to collecting dust scattered on a smooth floor.

[0002]

2. Description of the Related Art A roll mechanism mounted on a bogie is rotated in a direction opposite to a rotation direction of a rear wheel by a gear mechanism from a rear wheel or a power transmission mechanism from a driving device to sweep dust on the floor surface and collect the dust in a dust box. Although it is dusty, when the floor is smooth, it is difficult for the roll brush to push the dust forward just to sweep it up into the dust box. In this case, a spatula for scraping up dust provided in front of the roll brush is raised and lowered by hand operation, and the spatula is grounded at a place where it has passed over pebbles and the like, and the pebbles and the like are forcibly flipped up and stored in a dust box.

[0003]

When the floor surface is rough and rough, the dust accumulated in the dents can be scraped up and collected by the tip of the roll brush, but when the floor is smooth, the tip of the brush moves the dust forward. In many cases, the dust does not sweep up and goes over the dust. Further, dust in a narrow place such as under a desk cannot be collected because the tip of the roll brush cannot enter.

[0004]

Means for Solving the Problems A roll brush is laid over the center of a bogie having a rotary brush mounted on a front portion thereof, is rotated by a driving device, and a suction / exhaust device is provided above the roll brush. On a floor sweeper equipped with a dust box for storing swept dust in front of the roll brush, a bracket is projected from the side wall of the bogie behind the position where the roll brush is mounted, and the shaft is rotatably suspended between the brackets. Then, the base end of the swinging rod is fixed to one of the protruding ends of the shaft, and the base end of the swinging rod and the base end of the connecting rod are coaxially fixed to the other protruding end of the shaft. The lifting plate is fixed and positioned in front of the roll brush. A roller cam is mounted at the eccentric position on the hub surface of the rear wheel to intermittently contact the connecting rod, and swings via the connecting rod every rotation of the rear wheel. Swing the moving rod intermittently, And an object thereof is to reliably dust collecting a roll brush scooping dust in plate scoop grounded synovial floor surface.

In addition, a handy type vacuum cleaner is mounted on a trolley, and is connected to an energizing device provided on the trolley to remove dust in narrow places, and a mop for wiping the floor is attached to and detached from the rear of the trolley. They can be installed freely and finish the floor beautifully.

FIG. 1 is a front view showing the present invention, and FIG. 2 is a plan view of the same. The central axis 2a of the roll brush 2 in which a belt-shaped brush group 2b is helically implanted on the central axis 2a is supported across the center of the side wall of the carriage 1.

A driving device 3 for an engine or an electric motor is mounted on a carriage 1.
Is provided, and the belt 4 is hung on the central shaft 2a of the roll brush 2 and is rotated in the direction of the arrow (FIG. 1).

An intake / exhaust device 5 having a filter-intake port and a sirocco fan (not shown) for sucking air containing dust swept up by the roll brush 2 is provided above the roll brush 2.

A dust box 6 for storing dust swept up by the rotation of the roll brush 2 is detachably provided in front of the roll brush 2, and the rear brush 7 is mounted on a rear portion of the carriage 1. The bracket 8 crosses rearward at the corner of the side wall of the bogie behind the position where the is mounted, and the bracket 8 rotatably supports the shaft 9 in a direction parallel to the center axis 2a of the roll brush 2.

The base end of a bell crank type swinging rod 10 is fixed to the projecting end of the shaft 9, and the base end of a straight connecting rod 11 is coaxially arranged with the swinging rod 10 at one projecting end of the shaft 9. In addition, they are fixed almost perpendicularly.

A scooping plate 13 for scooping up a large amount of dust such as wood chips and pebbles scattered on a smooth floor with a roll brush 2 is fixed between the leading ends of the swinging rod 10.

A roller cam 14 is rotatably mounted at an eccentric position of the hub surface 7a of the rear wheel 7 and is brought into contact with the connecting rod 11 for each rotation of the rear wheel 7 to be integrally fixed to the connecting rod 11. The grounding of the scooping plate 13 and the bouncing operation of the scooping plate 13 are intermittently repeated with the swinging rod 10 centered on the fixing point to the shaft 9. In the figure, 15 is a rotating brush, 16 is a caster, 17 is a mop for wiping the floor, which is detachably attached to the rear part of the trolley 1, and FIG. 3 is a handy type vacuum cleaner 18 mounted on a vacuum cleaner according to the present invention. In the case where the roll brush 2 cannot be inserted into the place under the desk or the like, it is connected to an energizing device provided on the carriage 1 to clean a narrow place.

[0013]

According to the present invention, fine dust scattered on a smooth floor surface or large-sized dust such as pebbles can be scooped up by the scooping plate 13 and swept up by the roll brush 2 to collect the dust in the dust box 6 reliably. The floor surface after dust collection can be further wiped clean with a mop 17 and finished beautifully. Further, since the roll brush 2 is a self-propelled type, the work can be performed lightly.

In a narrow place such as under the desk where the roll brush 2 cannot be inserted, the roll brush 2 can be cleaned using the provided handy type vacuum cleaner 18.
