Title
(EN) SCREENING DEVICE
(FR) DISPOSITIF DE CRIBLAGE
Abstract
(EN)
This invention relates to a screening device, intended to be detachably fastened on a bucket of a digging machine, which in a suitable way comprises a hydraulically operable arm, which is arranged to be detachably fastened on the bucket, the outer portion of the arm comprising a plate-formed means provided with two hooks, which are intended to mesh with means on the bucket, which are adapted to these ones, and the plate-formed means being moveably arranged in relation to the arm by means of hinges and a hydraulic piston cylinder. According to the invention the screening device is characterized by the combination of the following features: the screening device comprises a frame portion (1) and a screening means (10), which are articulately fastened to each other, and which can be adjusted in direction towards or from each other in a hydraulic way, the hydraulic power being taken from the digging machine (4); the frame portion (1) is provided with two hooks (22, 23), which are intended to be fastened onto means (20, 21), which are adapted to these ones and are arranged on the bucket (3) for positioning of the screening device on the bucket, the frame portion (1) being fastened by squeezing against the bucket (3) by means of the plate-formed means (5) on the outer portion of the arm (6) of the digging machine.

La présente invention concerne un dispositif de criblage conçu pour se fixer de façon détachable sur le godet d'une pelleteuse comportant normalement un bras à man÷uvre hydraulique. Le dispositif de criblage est agencé pour se fixer de façon détachable sur le godet. La partie extérieure du bras comporte un organe plat pourvu de deux crochets qui sont conçus pour s'engager dans des organes du godet prévus pour ces crochets. L'organe plat est mobile au bout du bras grâce à une articulation et un cylindre à piston hydraulique. La particularité de l'invention est de combiner deux caractéristiques: d'abord, le dispositif de criblage comporte un châssis (1) et un crible (10) qui s'articulent l'un sur l'autre et qui peuvent s'écarter ou se rapprocher l'un de l'autre sous l'effet d'un actionnement hydraulique, l'énergie hydraulique étant fournie par la pelleteuse (4); ensuite, le châssis (1) est pourvu de deux crochets (22, 23) conçus pour se fixer sur des organes (20, 21) prévus pour ces crochets et agencés sur le godet (3) de façon à positionner le crible sur le godet. En l'occurrence, le châssis (1) est attaché au godet (3) grâce à la pression qu'exerce contre le godet l'organe plat (5) fixé à la partie extérieure du bras (6) de la pelleteuse.
