Description

DESCRIPTION OF THE DRAWINGS

[0016] To complete the description, the present specification is accompanied by a set of figures constituting an integral part of the same, which represent the following:

[0017] FIG. 1 shows a perspective view of the device for cleaning artificial turf object of the invention.

[0018] FIG. 2 shows an exploded view of all of the components of the device for cleaning artificial turf object of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

[0019] The object of the present invention, as previously mentioned and as can be seen in the figures, is a device for cleaning artificial turf comprising a frame (1) supported on four wheels (2), the wheels (2) being connected to a front axle (3) and to a rear axle (4) in pairs.

[0020] The device for cleaning artificial turf object of the invention comprises an electric motor (5) housed in an upper part of the frame (1) and protected by an upper cover (6) that has a plurality of slits (7) for cooling the electric motor.

[0021] Also located on the inside of the frame (1) is a roller shaft (8) that holds a single brush roller (9), which has a plurality of bristles (10) distributed in one direction on one half of the brush roller (9) and in the opposite direction on the other half of the brush roller (9), and thus the rotation of the roller shaft (8) in a single direction enables the brush roller (9) to sweep the dirt using the entire the surface of the brush roller (9) when passing over the artificial turf.

[0022] The front axle (3) is a pivoting axle, which allows the frame (1) to be lifted and lowered and allows the brush roller (9) to be moved closer to the artificial turf, while the rear axle (4) is an axle fixed in its position in the frame (1).

[0023] In order for the roller shaft (8) to rotate, the device object of the invention has a transmission for transmitting the rotation of the electric motor (5) situated in the upper part of the frame (1) to the roller shaft (8) which is in a lower part of the frame (1), logically as close to the ground as possible to condition the artificial turf.

[0024] The transmission comprises a transmission belt (11) and a plurality of rollers (12) on the roller shaft (8) which achieve a gear reduction in the rotational movement that reaches the brush roller (9) from the electric motor (5).

[0025] The device object of the invention has collection box (13) connected to the rear part of the frame (1) which, by means of a rear outlet of the frame (1), is configured for collecting the debris that the brush roller (9) picks up on the turf, sweeping and projecting them into the collection box.

[0026] The collection box (13) is configured to be able to be removed from the frame (1) and be emptied when necessary, and to this end it comprises two hook-shaped ends that are housed on a rear part of the frame (1).

[0027] When the collection box (13) is not fixed to the frame (1), the device object of the invention comprises a hinged cover (14) which covers the rear part of the frame and is fixed to the upper part of the rear outlet of the frame, such that it can rotate around the fastening area.

[0028] In addition, the collection box (13) has a parallelepiped shape, with two side walls (15), a base (16), a rear wall (17) and a ceiling (18), such that the ceiling (18) extends over the side walls (15) but leaves space so that the hinged cover (14), in the position in which the rear outlet of the frame (1) is open, is supported on the side walls (15) and, along with the ceiling (18) of the collection box (13), covers the entire upper part of the aforementioned collection box, such that with the collection box (13) fixed to the frame, a closed space behind the rear outlet of the frame (1) is created, where the debris picked up by the brush roller (9) ends up.

[0029] To be able to handle the device object of the invention, a U-shaped structure (19) is fixed to the frame (1), fixed to the frame (1) by branches of the U shape, while a core serves as a support for the user of the device. Furthermore, the U-shaped structure (19) serves as a guide for an electric installation that provides electric energy to the electric motor, such that coming from the core of the U is a cable (20) with a plug (21) to be able to connect the device object of the invention to the electrical grid.

[0030] Located at the same point at which the cable (20) with the plug (21) comes out, there is a safety switch of the device object of the invention, of those known in the state of the art, such that it is only necessary to press a bar (23) and a button (22) at the same time to start up the electric motor (5) of the device object of the invention.

INDUSTRIAL APPLICATION

[0031] The device for cleaning artificial turf object of the invention can be applied in the industry of light garden machinery.
