Definitions

the invention relates to a sieve grate for separating Bulk goods with grate bars arranged side by side, that form gaps between themselves and those on crossbars are attached.
Conventional sieve grids for rough separation of Bulk goods consist of crossbeams with larger ones Distances and screwed or screwed or on or welded-on grate bars with smaller distances. According to the arrangement of the crossbars and the Rust bars result in gaps.
the grates can be arranged with an inclination and / or in steps.
the material of these gratings is made of steel. Are the grates screwed together, so are assembly and disassembly complex. If they are welded together, there is assembly and disassembly also complex and it can not individual grate bars to be replaced, but it must the entire welded frame can be replaced. There is also a risk of rust formation. For softer ones materials to be screened / dewatered (for Example root crops such as potatoes, beets, etc.) damage from the hard materials.
the object of the invention is in a sieve grid Production, assembly, disassembly and simplify and improve maintenance and to achieve high operational reliability.
this object is achieved by that the grate bars on the crossbar are positive are releasably attached.
Such a grate screen is particularly easy to manufacture and preferably to be assembled without tools. In particular, it has high operational reliability and an easy repair on.
the grate has at least two crossbeams 1 and 1 releasably attached grate bars 2.
the one for crossbeams and grate bars used is rubber-elastic preferably polyurethane 5.
the cross beams and the Grate bars can be provided with reinforcements.
the Crossbars contain open ones Mounting recesses 6 in which the grate bars 2 from Be pushed in from above.
One in particular sawtooth-shaped locking recess 7 in the Mounting recess 6 in the crossbar 1 and a Locking projection 8 of the same cross section on Grate bar 2 prevent accidental loosening by the application vibration could occur.
the gap length is determined by the distance between the Crossbar determined.
the grate bars 2 preferably have a profile tapering downward in cross section Gap area to avoid the jamming of boundary grain. For further protection of "soft" screenings and for the head profile of the Grate bar preferably be rounded (Fig. 4, 5, 6).
the mounting profile 9 is preferably at the end arranged at the ends of the grate bars 2.
the Mounting profiles 9 can also be centered on the grate bars 2 to be appropriate. This is the top of the Crossbar 1 and that of the grate bars 2 on one level. To increase the open screen area, the The mounting profiles on the grate bars protrude downwards (Fig. 8a). The grate bars run when assembled then over the crossbar, which is such a continuous Form a gap.
Mounting profile 9 is angular. But as soon as one conical gap course is necessary, this is achieved through tapering training in the direction of conveyance the grate bars and / or by a widening one another Arrangement of the grate bars (Fig. 9, 10) so that the columns widen between the grate bars.
Mounting profile preferably round, especially cylindrical (Fig. 9, 10) formed, that is, the mounting profiles are down (Fig. 9a to 9c) or face (Fig. 10a to 10c) parts protruding from the grate bars, especially cones with in particular round horizontal cross section and in particular cylindrical shape with vertical cylinder axis. In order to distribution of the screenings is achieved at the same time.
FIG. 2a and 2b can preferably in the lower area of the grate bars on one or both sides Spacer knobs (3a and 3b) must be worked in on the side.
the Flank slope 3-20 degrees, preferably 5-10 degrees should and the mounting profile with an oversize is to ensure a secure hold on the crossbeam to reach.
horizontal Collar bolts 11 are provided, each half in semi-cylindrical recesses of the mounting profile 9 and the mounting recess 6 on both sides of the mounting profile insert and therefore preferably the Locking projection 8 and the locking recess 7 replace.
Vertical drainage or cleaning openings 10 extend from the bottom of the locking recess down through the crossbar.
the mounting profiles under the Profile bars may be arranged. As a result, the Crossbeam below the profile bars.
the recesses and mounting profiles are subject to stress conical.
