Overhead feeders for cleaning machines, in particular caterpillar belt cleaning machines

The invention relates to an overhead feeder for Cleaning machines, such as those used in particular on caterpillar belt cleaning machines. Through the last Years of increased performance of the centrifugal units for the abrasive of the cleaning machines has meant that the blasting times are increasing could be shortened »but the non-productive times, that isί the times for loading and unloading the Cleaning machine not shortened in the appropriate ratio could be »so that the total time that so-. said batch time despite the increase in performance of the Centrifugal units still remained relatively long «. ... ■ ■ .-., - ■ .. - .-

The introduction of the overhead feeder consisting of a pre-filling bunker with automatically controlled closing flap arranged above the filling opening of the machine, one that can be automatically inserted into and withdrawn from the filling opening of the plastering machine Transfer rod before and corresponding automatic control of the filling opening closing There was a sliding door, could shorten the times necessary for loading the machine, but brought it but a considerable technical effort with it, once in the with a special drive

to be provided »telescopically into the filling opening movable transfer chute j also in the. additional, also to be provided with a special drive Sliding door in front of the filling opening and in the correct order of the opening and closing Closing operations causing control device existed. Difficulties also arose from the need for the filler opening to be closed a flap to use a sliding door, jieil the Arrangement of the pre-filling bunker just above the plastering machine and the one that closes the outlet opening The flap, which was also to be provided with a special drive, prohibited the use of a corresponding opening flap for the machine filling opening.

The invention avoids these difficulties and reduces the manufacturing costs by proposing the unloading flap of the pre-filling bunker as in to form the filling opening of the cleaning room of the cleaning machine pivotable transfer chute, and thereby expedient to train the shop container as part of the cleaning machine housing, when implemented This proposal not only eliminates the need for a special, self-propelled, and to provide sequence-controlled transfer chute, but also the further need to connect the filling opening of the cleaning room with a separately driven, and to equip controlled door, as the inventive designed and arranged unloading flap takes on all of these tasks together. There are also no special supporting structures for the pre-filling bunker necessary, but only an appropriate dimensioning of the plastering machine housing box,

We do the transport level on a caterpillar belt cleaning machine of the unloading conveyor at a distance into the area vertically below the strand of the caterpillar belt arranged running, and between the discharge end of the crawler belt and the conveyor within the Plaster housing created an inclined slide, then a system that is completely closed to the outside is created for the loading and unloading of the plastering machine in the case of extraordinary low manufacturing costs and space requirements

The invention is illustrated with reference to the drawing Embodiment explained in more detail. The drawing shows

a caterpillar belt cleaning machine seen from the side, in schematic representation cut.

The box-like support housing 1 of the cleaning machine with the base part 2 accommodates the caterpillar belt 3 and the centrifugal unit 4. The pre-filling hopper 5 sits on the machine housing, where the closure flap for the filling opening of the housing is arranged in the case of the usual housing shapes. The discharge flap 6 of the pre-filling bunker can be pivoted about a pivot axis 7 from the VeX ¹ final position shown in full lines into the unloading and transfer position shown in broken lines; In the transfer position, it rests on a support extension 8 of the cleaning machine housing. The pivot axis 7 is arranged below the ignition edge of the discharge opening of the pre-filling bunker within the cleaning machine housing.

In the area perpendicularly below the lower strand 3a of the caterpillar belt 3 is a, here as a loop conveyor 9 trained discharge conveyor provided, which the cleaned goods on the slide-like part la ties cleaning machine housing is fed when the caterpillar belt is moved in the direction of the arrow marked r.'it 10. On the outlet side, the loop conveyor has a screen section, not shown, which is used for separating the Blasting media is used.

As can be seen without further ado, this requires Formation of the loading device of the cleaning machine no special locking door for the cleaning machine housing and no additional transfer chute, since the closure flap 6 fulfills all of these tasks. the necessary automatic stop, if such an automatic seems appropriate to ~ the coordination between the caterpillar belt drive and the flap movement be restricted.
