Description

Die Erfindung betrifft Siebeinrichtungen, die auch als Plansichter zum Absieben von Schüttgut gemischter Körnung bekannt sind. Bei herkömmlichen Plansichtern steht die differenzierte Trennung des Siebgutes im Vordergrund der Patentansprüche.The invention relates to screening devices, which also as Plansifters for screening bulk material of mixed grain size are known. At Conventional plan sifters stand for the differentiated separation of the material to be screened Foreground of the claims.

Im Gegensatz dazu will diese Erfindung Auffang und Abtransport des gesiebten Materials verbessern. Ferner soll die manuell betriebene Vibration von Sieb und Siebgut erleichtert und verbessert werden. In der GB 20 52 311 A wird ein Gartensieb mit ähnlichen Eisenschaften beschrieben. Es besteht prinzipiell aus einem gerahmten Siebgitter und einem Fußgestell. Das Fußgestell ermöglicht die Montage des Siebes auf den Rand einer Schubkarre. Dabei kann der Rahmen in einem beliebigen Winkel zum Fußgestell angebracht werden.In contrast, this invention seeks to collect and remove the improve screened material. Furthermore, the manually operated vibration of sieve and screenings can be facilitated and improved. In GB 20 52 311 A a Garden sieve with similar ice properties described. It basically consists of one framed screen grille and a base. The base frame enables assembly of the sieve on the edge of a wheelbarrow. The frame can be in one any angle to the base frame.

Im Gegensatz zur oben beschriebenen Erfindung GB 20 52 311 A werden nun, neben erheblichen konstruktiven Erleichterungen, weitere Benutzervorteile erreicht. Im einzelnen betrifft dies:In contrast to the invention GB 20 52 311 A described above now, in addition to considerable structural simplifications, further user benefits reached. In particular, this concerns:

  • i) die Erweiterung der manuell betriebenen Anregung von Sieb und Siebgut von bisher einem auf zwei Freiheitsgrade.i) the expansion of the manually operated excitation of sieve and screenings from so far one on two degrees of freedom.
  • ii) der Abtransport des gesiebten Materials kann erfolgen, ohne daß ein Ab- oder Umbau der Siebvorrichtung notwendig ist.ii) the screening of the screened material can take place without a removal or Conversion of the screening device is necessary.

Dazu wird das Sieb an vier aufrechten, rechtwinklig angeordneten Baustahlstangen gleicher Länge befestigt, so daß es sich anschließend in einem Abstand von ca. 1 m parallel zum Boden befindet. Die zueinander parallel aufgerichteten Stahlstangen bilden ein Viereck. Die Bodenverankerung der Stangen erfolgt mit Hilfe eines Holzrahmens, der eine einseitige Aussparung besitzt, um den Zugang mit einer Schubkarre oder ähnlichen Transportmitteln zu ermöglichen. Die Geometrie der Anordnung erlaubt einen allseitigen Zugang des Betreibers. Die Flexibilität des Gestänges ermöglicht die Vibrationsanregung von Sieb und Siebgut. Dabei ist wesentlich, daß konstruktionsbedingt die Bewegung des Siebes parallel zum Boden in alle Richtungen möglich ist.For this purpose, the sieve is arranged on four upright, right-angled Structural steel rods of the same length attached so that it is then in one Distance of approx. 1 m is parallel to the floor. The parallel to each other Upright steel bars form a square. The rods are anchored to the floor using a Wooden frame that has a one-sided recess around the Allow access with a wheelbarrow or similar means of transport. The The geometry of the arrangement allows the operator access from all sides. The Flexibility of the boom enables vibrations to be sieved and screened. It is essential that the movement of the sieve parallel to Soil is possible in all directions.

Im folgenden wird das bevorzugte Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert, die die räumliche Darstellung einer erfindungsgemäßen Siebhalterung mit Basisgitter zeigt. The preferred embodiment of the invention is described below a drawing explains the the spatial representation of a sieve holder according to the invention Base grid shows.  

Zum Aufbau der Siebhalterung werden die fünf Bodenrahmenteilstücke 10-11 gemäß Fig. 1 zu einem offenen Viereck angeordnet. Die vier Baustahlstangen werden durch die paarweise übereinander liegenden Bohrlöcher getrieben. Auf das so entstandene Gestänge wird das Basisgitter gelegt. Es dient dann als Halterung für mögliche feinmaschigere Siebauflagen.To construct the screen holder, the five base frame sections 10-11 according to FIG. 1 are arranged in an open square. The four structural steel rods are driven through the boreholes lying in pairs one above the other. The base grille is placed on the frame thus created. It then serves as a holder for possible fine-meshed screen supports.

Einsatzbereiche der Erfindung sind in Anlehnung an herkömmliche Gartensiebe vorzugsweise im Garten- und Landschaftsbau sowie im Forst- und Bauwesen zu erwarten.Areas of application of the invention are based on conventional garden sieves preferably in gardening and landscaping as well as in forestry and construction expect.
