Abstract

Zu einer mobilen Sandreinigungsvorrichtung gehört ein auf der Sandoberfläche (3) fahrbares Gestell (10), an dem ein Sandelevator (60) verstellbar, insbesondere absenkbar und anhebbar gehalten ist, der mit einer endlosen, motorisch antreibbaren, umlaufenden Fördereinrichtung (70) ausgerüstet ist. Die jeweilige Grabtiefe hängt vom Ausmaß der jeweiligen Verstellung/Absenkung des Sandelevators (60) bezüglich des Gestells (10) ab. Sandkästen können ein Sandtiefenprofil mit unterschiedlichen Sandtiefen aufweisen, und eine sachgerechte Sandreinigung erfordert eine Anpassung an dieses Sandtiefenprofil. Um ein Verfahren und/ oder eine Vorrichtung zur insbesondere gewerblichen Sandreinigung anzugeben, bzw. bereitzustellen, das/die eine objektive Angabe und Kontrolle der tatsächlich gereinigten (aufgelockerten, belüfteten, gesiebten bzw. umgewälzten) Sandmenge ermöglicht, ist vorgesehen, daß die Sandreinigungsvorrichtung mit einer Signalverarbeitungseinrichtung (100) ausgerüstet ist. Weiterhin ist ein Grabtiefensensor (Sl) vorhanden, welcher die jeweilige Verstellung/Absenkung des Sandelevators (60) bezüglich des Gestells (10) erfaßt und entsprechende elektrische Signale erzeugt und an die Signalverarbeitungseinrichtung (100) übermittelt. Vorzugsweise kann dieser Grabtiefensensor ein Längenmeßsensor sein.

A mobile sand cleaning device includes a frame (10) which can be moved on the sand surface (3) and on which a sand elevator (60) is adjustable, in particular lowered and raised, which is equipped with an endless, motor-driven, rotating conveyor device (70). The respective digging depth depends on the extent of the respective adjustment / lowering of the sand elevator (60) with respect to the frame (10). Sandpits can have a sand depth profile with different sand depths, and proper sand cleaning requires adaptation to this sand depth profile. In order to specify or provide a method and / or a device for in particular commercial sand cleaning, which enables an objective indication and control of the actually cleaned (loosened, aerated, sieved or circulated) amount of sand, it is provided that the sand cleaning device with a Signal processing device (100) is equipped. There is also a digging depth sensor (S1) which detects the respective adjustment / lowering of the sand elevator (60) with respect to the frame (10) and generates corresponding electrical signals and transmits them to the signal processing device (100). This digging depth sensor can preferably be a length measuring sensor.
