Vibrationsausschlagrostc are known with un- placement of molding boxes with or without a casting, Balancing drive, including those that simultaneously oscillate a shape that is arranged under the grate exert the effect and wherein a resonating tub 2 is open at the breaker rope end 3 and Gutter the sand that has fallen through the grate then continues into the sloping one without interruption transported. There are also additional equipment breaker gap 4 over. The chemically bound The large passage openings necessary for such vibration conveyors are known to be necessary for molding sand for chopping tubers. These consist of 60 »and 18 of the knock-out grids, which require pre-marking.

It should be noted here that it is not limited to such a drive, otherwise the passage openings of a vibrating mandrel can also be used, for example, with a hydraulic

Claims (7)

Impact rust door longebundenc molding sand be small Patent claims: can, so that only small bulbs are to be processed. In the case of chemically bound molding sands, the 1. Vibrating grate with crusher, the grate-like means not, as the through openings of the Holding back molding box and castings, sand 5 rash rosles must be very large, which means But lets the tubers pass, resulting in large tubers, and because the tubers a lot indicates that under the grate (1) are harder than those of clay-bound Forrnsanan known each other, open to one side, with each other. Besides, the amount of these crumbs is bigger, vibrating tub (2) is provided, which is The reason is that in contrast to the longebis at the beginning of an inclined io bound molding sand, which mostly breaks up by itself (4), one of which is encountered, almost all of the sand is in the form of these hard tubers flat crushing jaw (6) from the extension of this accrues. Tub is formed. "To recover such chemically bound 2. vibrating grate with crusher according to claim 1, molding sand was therefore previously necessary, a strong characterized in that the upper, not an- 15 and large breaking device immediately behind Provide driven crushing jaw (13) to the exit of a shaking grate, as bulbs of here Crushing gap (4) into a horizontal size that comes into question badly or even at all Do not allow the axis (15) of the oscillating counter-pulse hammer to be transported on continuous conveyors, especially (14) passes that its movement impulses from special with increasing promotion, and because the the driven jaw (6) receives. 20 Reclamation of the sand, crushing in each 3. vibrating grate with crusher according to claim 1, makes the case necessary. The invention replaces that characterized in that the previous vibration devices for knocking out drove an unbalance exciter (7), the directed molding box and the separate breaking of the tubers. Vibrations generated. inJcm with a drive within a device 4. vibrating grate with crusher according to claim 1 25 device both the knocking out of the molding box as and 2. characterized in that the Schwin- also the breaking of the tubers are carried out level (8-8) a slope (9) of 20 to It is characterized by an under the grate 40 ° from the vertical in the direction of the crusher, open to one side and oscillating has.
