摘要:
The invention relates to a heavy machine-operated sieve screen bucket. 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 the material to be screened can be placed. There are rotatable shafts (4) below the screening surface (2). The shafts (4) are provided with blades (5), which are projecting from the shafts and which extend through the screening slots to above the screening surface (2). The blades (5) taper in a wedge-like manner towards their rounded tips. Side edges of the blades (5) are substantially straight and the angle between the same is in the range of 20-28°.

The invention relates to a replaceable blade piece (1) of a working cylinder of a screen crusher, which as viewed from the side is substantially T-shaped. The blade piece has a frame portion (2) forming the vertical shaft of the T and a blade portion (3) forming the horizontal arm of the T, the longitudinally opposite front surfaces of which form the actual work surfaces (4). The frame portion (2) has a through hole (5) extending in the longitudinal direction of the blade portion (3). Into the frame portion (2) is formed, on the opposite sides containing the hole (5), a channel-like section (6), which extends in the vertical direction of the frame portion (2), between the edge areas (8, 9) of the side with the hole (5). The invention further relates to a replaceable blade piece holder (11) of a working cylinder of a screen crusher, said holder having a U-shaped frame portion comprising arm portions (12, 13), through which extends a longitudinal hole (15) of the frame portion, and a bottom portion (14) with a curved bottom connecting the arm portions (12, 13). On the opposite surfaces of the arm portions (12, 13), onto their middle area is formed a bulge (16), which extends in the vertical direction of the arm portion, travelling at the hole (15).

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. 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.
摘要:
A screening, c rushing or mixing bucket which is designed as the bucket of an excavating machine or a bucket loader, comprising a bottom plate (1), side walls (2), and working drums (3), which are rotatable about their axes at a rear part of the bucket and which, while in rotation, effect screening, crushing or mixing of a material present in the bucket and at the same time delivering of a screened, crushed or mixed material out of the bucket between or through the working drums (3). The bucket also includes enclosures (4) for a transmission and bearing assemblies of the working drums (3), said enclosures being defined by frame panels (5) capable of being fitted with bearing cups (6) for the drums (3). Tool flanges (11) are provided with a butt collar or butt expansion (12a), extending around the drum shaft (9, 10) and dimensioned in the drum shaft direction in such a way that, with the tool flanges (11) at a desired distance from each other, between the butt collars (12a) remains a gap (s) for a welded joint. Two tool flanges (11) and the drum shaft (9, 10) are attached together by a single welded joint present in the gap (s).

The invention relates to a screening, crushing or mixing bucket, which is formed into a bucket of an excavating machine or bucket loader. The bucket comprises a bottom plate (1), side walls (2), and at the back of the bucket working drums (3) 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 (3). In the bucket are casings (4) for the power transmission and bearings of the working drums (3). The casings (4) are limited by frame plates (5) to which the bearing housings (6) of the drums (3) are attachable. On the frame plate (5) and/or on the inner side of the inner wall (2) is fixed a mudguard (10), which extends between the shafts of the working drums (3), next to the lead-throughs of the shafts, and the mudguard (10) comprises cut-outs (11) for receiving the shafts of the working drums (3).
