Patent number: 9481014Abstract: The invention relates to a sieve screen, which can be positioned in a utility machine-operated screen bucket or in a screening station maneuverable with its own actuator. As shown in FIG. 7, a plurality of screening plates (3) are spaced from each other and establish a screening surface (2), which is provided with screening slots and on top of which can be placed the material to be screened. Rotatable shafts (4) are present below the screening surface (2). The shafts (4) feature blades (5), which protrude from the shafts and extend through the screening slots to above the screening surface (2). Fraction size is adapted to be changed without removing the shafts (4), by re-grouping the blades (5) and a necessary number of the screening plates (3). The blades (5) can be grouped in such a way on the shafts (4) that at least two blades (5) are set adjacent to each other and the adjacent blades are located within the same screening slot.Type: GrantFiled: August 13, 2015Date of Patent: November 1, 2016Assignee: Allu Finland OyInventor: Antti Rautamies

Patent number: 8122620Abstract: A screening, crushing or mixing bucket is formed into a bucket of an excavating machine or bucket loader. The bucket comprises a bottom plate, side walls, and at the back of the bucket working drums rotatable about their shafts, which screen, crush or mix the material in the bucket as they rotate and at the same time deliver screened, crushed or mixed material out of the bucket, between or through the working drums. In the bucket are casings for the power transmission and bearings of the working drums. The casings are limited by frame plates to which the bearing housings of the drums are attachable. On the frame plate and/or on the inner side of the inner wall is fixed a mudguard, which extends between the shafts of the working drums, next to the lead-throughs of the shafts, and the mudguard comprises cut-outs for receiving the shafts of the working drums.Type: GrantFiled: January 28, 2010Date of Patent: February 28, 2012Assignee: Allu Finland OYInventors: Ari Männikkö, Joonas Eloranta, Anatoli Lappalainen
