Sand cleaning machine

A sand cleaning machine (also called " sand processing machine " or " sand bonuses " ) or beach cleaning machine ( short beach cleaner) is an inserted for cleaning and surface preparation of sandy beaches, sand volleyball courts or playgrounds mobile device. The term " sand bonuses " has been formed in accordance with resurfacers on artificial ice rinks, which have received the generic name for the inventor and manufacturer of Frank J. Zamboni in English speaking countries.

Operation

A sand cleaning machine is either a self-propelled vehicle on wheels or crawler, which is driven by a motor, or a trailer for a tractor. Usually gas powered or diesel motors are used for propulsion. Larger machines are attached as a pendant on Unimogs or tractors. This utility vehicles come mostly from the field of agriculture or municipal engineering and enable the use of more complex treatment plants. The smallest units are performed by the operator and pushed like a lawn mower.

The sand is transported on a pick up and isolated on a shaker or sifter in different large and heavy components. The machine separates characteristic waste in a separate container and gives the sand back to the beach or the playing field. Not only coarser particles are sorted depending on the process, but also excreted finer fractions such as silt or silt. The sand comes in contact with air, is broken and has a lower valence and higher flowability. For sports applications such as playgrounds so hygiene and fall protection be improved.

Application

At the 1996 Summer Olympics in Atlanta, the term " sand bonuses " has been applied to stationary systems with which the long jump pits were smoothed after the jump. The sports official Phillip L. According to Henson, the athletes were very pleased. Among the possible elimination of the jobs of human scavengers who must retrain to computers in the wake, Henson said only that it was the traditional man-machine competition.

A special feature of the 2008 Summer Olympic Games in Beijing were remotely controlled, futuristic sand Bonis, which were used for the beach volleyball courts of the tournament in the Chaoyang Park.

An out sporting application were sand Bonis, which were used for the cleaning of beaches after the oil spill in the Gulf of Mexico in 2010. The machines used therein on the Gulf of Mexico are the Members of the Company Cherrington from North Dakota, where there are no beaches. They are usually to clean the tourist beaches of human legacies such as cigarette butts and broken glass and for the removal of sharp-edged shells go. Smaller machines clean sand in children's playgrounds and sandboxes.

The 36 km long beaches of the Gold Coast in Queensland, Australia are visited by millions of tourists every night and cleaned the area between the water line and the dunes of four tractor -drawn beach cleaning machines. This type refers to the top 15 -cm layer of sand and cleans them. Other parts of the beach region only be visited weekly. A total of 31 tons of gravel, waste, seaweed, jellyfish and flotsam smaller are removed weekly.

In 2009, the Miami -Dade County, Florida, in a tender conducted a competition for beach cleaning, where the four leading North American producers took with their devices: Barber with Surf Rake, Cherrington with Beach Cleaner, Rockland with Beach King and Kässbohrer with BeachTech. In the competition there was in addition to the acquisition and operating costs and the cleaning result also depends on the wrong recorded sand, as this is added the waste containers ahead of schedule and the beach hurt by sand erosion.
