Description

Sweep assist device for sweepers.

Background of the invention

The present invention relates to a sweeping aid device to be applied, in particular, to sweepers in general.

As is known, sweepers are used in urban street cleaning applications, and comprise normally mechanically driven brushes, designed to sweep the surface of the street and collect garbage from it.

The prior art sweepers operate from optimally under certain conditions, for example when the Street is free and lacks obstacles.

However, since there are obstacles, such as parked cars and the like, cleaning brushes cannot reach the edge of the street next to the sidewalk, where the most of the dirt, including that which comes from the sidewalk.

In order to overcome the inconvenience above mentioned, an operator moving on land can pick up, within certain limits, dirt and garbage using a brush or similar, to get the garbage collected accessible to the sweeper brushes.

However, this operation is very tired and, In addition, it is not possible to remove dirt and debris, example, under parked cars.

Patent DE 2916012 describes a device for sweeping aid comprising an oscillating arm mounted on the top of a sweeper, the arm being coupled to a throws blower, to allow the operator to move in dirt collect dirt from areas under cars parked and send it to the sweeping brushes.

Summary of the Invention

The objective of the present invention is provide a sweeping aid device that does not require no physical effort by the operator and can also be used for a comparatively long period of time.

According to the present invention, a sweeping aid device as set out in the claim 1. Preferred embodiments of the invention are described in the dependent claims.

This sweeping aid device can move automatically, so that the movement of the sweeping operator, who must simply grab the spear.

It comprises a series of operating arms servo-controlled, to which the blower lance is applied. The servomotors that control the arms are preferably controlled by rotary displacement sensors, which are actuated by the operator movement

Description of preferred embodiments

In relation to the numerical references of the figures mentioned above, the sweeping aid device according to the present invention, which has generally been indicated by the reference number 1, comprises a first arm 2, in a first end portion thereof, articulated to cabin 3 of a sweeper 4 and that supports, in its second end part, a second arm 5.

The free end of the second arm 5 supports a support element 6 for a duct 7 extending vertically, at whose end a blower lance 8 is coupled which It can be operated by an operator 9 that travels on land.

The first arm 2 is articulated to the cabin 3 by a respect wheel 10, said first arm 12 being rotatably controlled by a servomotor 11.

The second arm 4 is articulated to the first arm 2 through a rotating support element 12 and is articulated rotatably by a second servomotor 12 through a system belt drive 14 and 15.

Blower lance 8 receives the air flow from blowing means, comprising a blower fan 16, driven by a motor 17, and adapted to transport air to through a first conduit 18 that extends into the first arm 2, through a flexible fitting 19.

The first air duct 18 is coupled to a second air duct 20, which extends into the second arm 5, through a passage inside the rotating support 12.

The second air duct 10 goes, in turn, coupled to the vertical duct 7 and, consequently, to the lance air blower 8.

Said air blower lance 8 comprises a push button panel 21, which can be used by operator 9 to control the flow of air and a jet of liquid, normally Water.

The movement of the device and, in consequently, the rotation of arms 2 and 5 and the conduit that extends vertically, they are servo-controlled, so that the operator 9 should limit himself to guiding the air blower lance 8, without No effort to move it.

For this purpose, the rotating support element 6 comprises rotation sensors 22 adapted to detect a rotating movement of the duct 7 extending vertically, applied by operator 9, when handling lance 8, and controlling the operation of servomotors 11 and 13.

The first arm 2 can rotate 240 ° from its initial or resting position, illustrated in figure 1, until its position of maximum rotation, in use, shown by the lines discontinuous in figure 5.

The second arm 5, in turn, can make a 340 ° rotating movement, thus allowing the operator use the air blower lance 8 on virtually any desired point.

The use of the sweeping aid device, according to the invention, it is schematically illustrated in figures 4 and 5.

As illustrated in the drawings, the arms articulated are designed and arranged to easily pass about possible obstacles present at the edge of the street, normally parked cars 23, so as to make the spear blower 8 is readily available to operator 9, for push dirt and debris causing them to pass under the parked car and be picked up by the brushes of the sweeper

Since the device is of the type servo-controlled, the operator must simply orient the lance air blower 8 to the desired direction, while the servomotors perform the work necessary to drive the arms.

It has been found that the invention reaches fully the intended objective.

In fact, the invention provides a sweeping aid device which, when applied to a sweeper, allows an operator to move on land to push waste and garbage to the sweeper brushes, without No effort and in a simple way.

In the application of the invention, the materials used, as well as the possible size, can be any, depending on the requirements and the state of the art.
