Description

  

   <Desc/Clms Page number 1> 
 



  Löffel für Baumaschinen 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 Schürfbewegung im Erdreich über diese gekrümmte   Fläche-9-abrollt,   so dass ein Festfressen des Löffels in ungünstigem Erdreich verhindert ist, weil der Schneidzahn-7-dabei eine nach aufwärts gerichtete Bewegung mit entsprechenden Hebelwirkungen ausführt. 



   Wie Fig. 5 zeigt, ist der Aufnahmekörper mit einer   Bohrung --10-- in Längsrichtung   versehen, in die der   Schneidzahn--11--mit   seinem   Einsatzstück--lOa--eingesteckt   und mit Hilfe eines   Querbolzens --12-- mit   dem Aufnahmekörper verbunden ist. Dadurch ist eine leichte Austauschbarkeit des Schneidzahnes ermöglicht. 



   Der Schneidzahn besitzt Meisselform. Damit der Meissel möglichst sicher und mit einer gewissen Führung vom Aufnahmekörper getragen wird, ist der Aufnahmekörper an seinem Vorderteil mit Keiloder   Kegelflächen--13, 14--   versehen. Der rückwärtige Teil des Schneidzahnes besitzt eine entsprechende Ausbildung. 
 EMI2.1 
 



   Die   Wangenflächen--3--des   Löffels laufen nach hinten konisch zu, um die Reibung mit dem Erdreich möglichst herabzusetzen. 



   Bei der in der Fig. 4 dargestellten Ausführungsform ist der Aufnahmekörper --5b-- unter dem Bodenvorderteil--16--des gekrümmten Bodens angeordnet. Die Art der Befestigung des Schneidzahnes ist die gleiche wie bei der Ausführungsform gemäss den Fig. l bis 3. Auch bei der Ausführungsform gemäss   Fig. 4 verläuft   die   Mittellinie--17--in   Richtung der   Mittellinie --18-- des   gekrümmten Bodens. 



   PATENTANSPRÜCHE : 
1. Löffel für Baumaschinen mit einem in Arbeitsrichtung konkav gekrümmten Boden, wobei an der Bodenvorderkante mehrere   meisselförmige   Schneidzähne angeordnet sind, die von Aufnahmekörpern 
 EMI2.2 
 Schneidzähne stetig und nach einer Tangente an die Mittellinie (8) des gekrümmten Bodens (2) in den Aufnahmekörper anschliesst, wobei diese Tangente parallel zur Arbeitsrichtung verläuft, die Aussenfläche (9) der Aufnahmekörper (5, 5a, 5b) in Arbeitsrichtung stromlinienförmig ausgebildet ist und dass jeder Aufnahmekörper   (5, 5a, 5b)   eine Bohrung (10) für die Einführung des Einsatzstückes (10a) des Schneidzahnes (7) aufweist.

 EMI1.1
 

 <Desc / Clms Page number 2>

 The digging movement in the earth rolls over this curved surface-9-so that the scoop is prevented from seizing in unfavorable soil, because the cutting tooth-7-carries out an upward movement with corresponding leverage.



   As Fig. 5 shows, the receiving body is provided with a bore --10-- in the longitudinal direction, into which the cutting tooth - 11 - with its insert piece - 10a - is inserted and with the aid of a transverse bolt --12-- is connected to the receiving body. This enables the cutting tooth to be exchanged easily.



   The cutting tooth has a chisel shape. So that the chisel is carried by the receiving body as securely as possible and with a certain guidance, the receiving body is provided with wedge or conical surfaces - 13, 14 - on its front part. The rear part of the cutting tooth has a corresponding training.
 EMI2.1
 



   The cheek surfaces - 3 - of the spoon are tapered towards the rear in order to reduce the friction with the soil as much as possible.



   In the embodiment shown in FIG. 4, the receiving body - 5b - is arranged under the front floor part - 16 - of the curved floor. The type of attachment of the cutting tooth is the same as in the embodiment according to FIGS. 1 to 3. Also in the embodiment according to FIG. 4, the center line - 17 - runs in the direction of the center line - 18 - of the curved bottom.



   PATENT CLAIMS:
1. Bucket for construction machinery with a bottom that is concave in the working direction, with several chisel-shaped cutting teeth being arranged on the front edge of the bottom, which are held by receiving bodies
 EMI2.2
 The cutting teeth adjoin the center line (8) of the curved bottom (2) in the receiving body continuously and according to a tangent, this tangent running parallel to the working direction, the outer surface (9) of the receiving bodies (5, 5a, 5b) being streamlined in the working direction and that each receiving body (5, 5a, 5b) has a bore (10) for the introduction of the insert piece (10a) of the cutting tooth (7).
 EMI2.3
