| 1992 | Invention patented by Jean C. Thoer on February 3rd, 1992. Abstract: Beach cleaning machine comprises a self-propelled vehicle carrying a tippable skip and at the front an apron adapted to pivot about an axis perpendicular to the longitudinal axis of the machine. The inclination of the apron can be varied and its lower forward end is provided with a blade adapted to dig into the ground. To the rear of the blade, extends a first grid conveyor discharging onto a conveyor belt adapted to convey detritus picked up by the apron to the skip. Above the first grid conveyor is a second grid conveyor provided with paddles and whose upper end is pivoted to one end of two links whose other ends are pivoted to the apron. Rams are coupled to the links intermediate their ends. The lower end of the second grid conveyor is connected to the apron by rams. The second grid conveyor is driven by a motor in an opposite direction to the first grid conveyor. The apron is in two parts, an upper part and a lower part. Each part comprises a grid conveyor driven by a motor. The lower part comprises at is forward lower end the blade and its upper part extends over the upper part. The lower part is slidably mounted on the upper part and can occupy two positions, an operative position in which the two apron parts are disposed one in front of the other and a transport position in which the two apron parts are stacked one on top of the other. |
