This invention is being applied to the equipment of the foundry, in particular to obtain casting eMUhi melted models, and can be used in installations for applying bulk refractory material to model blocks coated with ceramic suspension. The known unit for dusting the prayer unit is zeunisty1-4 a material comprising a chamber, a porous partition and a compressed air supply collector, in which the dusting is carried out in a fluidized bed ij. The disadvantage of the installation is that the sanding is carried out with one fraction of sand, and for applying another fraction a similar installation and transfer of the model is necessary. This delay is dangerous because it can dry the suspension and the next coating, the sand can not stick to it. The closest in technical essence and the achieved result to the proposed is an elevator sandbox containing a chamber, dusting of model blocks, an elevator, a sweat hopper and a manipulator for moving and turning the model block 2. The disadvantage of this grain elevator is that the sanding is also carried out in one fraction of the sand. Sand flow from the hopper to the vibrating screen is uneven. To clean the parts of the manipulator hands that are wetted by the suspension, additional installation is necessary - sandblasting, located in another place. sandblasting and moving the manipulator to the sandblaster reduces the productivity; The purpose of the invention is the leadership of ka. model blocks and performance enhancement. This goal is achieved by the fact that the elevator sandbox containing a sprinkling chamber of model blocks, an elevator, a distributing hopper with a vibrating screen and a manipulator for moving and turning the model block, is equipped with an additional elevator, conveyor connecting the elevator with bukkerom, as well as an elevator, overlapping the lower part of the chamber, and a device for cleaning the working parts of the manipulator, which is built into the chamber wall, and in the bottom of the bunker there are grilles, one of which has funnel-shaped cells and another TCA is in the form of longitudinal strips that of overlapping bottom cell and coupled with vibrating screen. In this case, the paOi device is cleaned.) Of the HFJIK.UIHOHO manipulator torus as separate containers that are located opposite each working part of the manipulator and are equipped with sandblasting nozzles fixed outside the tanks in a concentric manner relative to the working parts of the manipulator, and the device is supplied with a drive. its horizontal movement. FIG. 1 shows a grain elevator, a general view, a section j in FIG. 2 - the same plan view; in fig. 3 - the same, a section, respectively, in the place of installation of the manipulator and the CLEANING DEVICE worker1: .x parts of the manifest bargaining ... The device includes a dusting chamber 1, two elevators 2 and 3, a feed bin 4, a conveyor belt 5, a vibrating screen b, a manipulator 7. In the bunker 4, there are gratings with cells B in the form of funnels 8 and longitudinal strips 9, In a narrow section of the dusting chamber gate 10 overlaps one or the other ;; anal depending on sand friction. The manipulator 7 has working parts 11 and 12, which are cleaned with the same sand by the cleaning device 13, consisting of two tanks 14 and 15 with sandblasting nozzles 16 and 17 installed in them; The entire device 13 is moved to the manipulator by a drive 18. The device is as follows. The sand of the fine fraction through the elevator 2 enters the conveyor 5, which supplies sand to the feed hopper 4. In the bunker 4, the grooves of which overlap the longitudinal strips, the grating 9, the sand fills the funnels of the grating 8. When the vibrating screen is turned on, the longitudinal strips begin to return -available movements, feeding and dispersing sand evenly throughout the vibrating screen b, Tew itself creating a uniform flow - sand rain. Using the manipulator 7, the model block is moved in falling streams of sand and simultaneously rotated so that its entire surface is saturated with sand. Unused sand through the fines canal at the bottom of the dusting chamber 1, opened by gate 10, goes to elevator 2 and goes up. The longitudinal bars of the lattice 9 play the role of a shutter, a flow meter and a diffuser. As flowmeters, they work by moving them in a vertical plane. When working with coarse sand, they include an elevator 3, which supplies sand to the conveyor 5, and

that is in OyiiKeii 4. IiJii6op 10 oTKpfjBapT is the coarse fraction channel and kills the fines channel. Unused sand is directed through the coarse fraction canal and is fed by elevator 3 to the top.

When cleaning the working parts of the manipulator, the cleaning device 13 is fed to it. These parts are in containers in the middle of the nozzles.

Sand 1k is given in the tank and then into the nozzles. The energy of the supplied compressed air is transferred to the sand, which also cleans the working parts of the manipulator from the crust, consisting of hardened slurry and sand.

The proposed elevator sanding allows improving the quality of model blocks and productivity by 1.3 times compared to the known.
