device is reciprocable and has a number of cutting pins. This clearing chain has the task of getting that out falling out of a chamber filter press arranged above the bunker To cut up the filter cake on its way into the funnel and then to crush and loosen it. The crushed filter cakes are then transported away by the trough chain conveyor and at the end of the Conveyor thrown off.

This known device is very complex, since the * clearing chain consists of a large number of intricately shaped cutting members and a special drive for their Requires back and forth movement. In addition, the known device cannot prevent the in the conveyed goods reaching the discharge funnel in front of the discharge side The front wall of the bunker accumulates and does not get into the conveyor there due to the formation of bridges.

The object of the invention is to avoid these disadvantages and to design the device for bunkering and pulling off viscous bulk goods in such a way that also the one on the Bulk material accumulating on the outlet side end wall is easily brought into the trough chain conveyor and from this can be transported away, so that the entire usable length of the bunker to accommodate the falling into it Material to be conveyed is available.

This object is achieved with the invention in that the comminution and circulation device of a i'friction and the cutting wave is formed immediately above of the trough chain conveyor is arranged in the area of the outlet-side end wall of the bunker.

This configuration has the advantage that the conveyed goods lying above the conveyor in the bunker outlet and pressed by the chain of the conveyor against the end wall of the bunker on the outlet side are loosened at this point and forced into the trough of the conveyor so that it can be transported away from it . This makes it possible to bunker even a sticky, moist viscous material to be conveyed, such as crushed sewage sludge filter cakes, and to pull it off with relatively narrow trough chain conveyors of about 500 to 600 mm in width. Since the filter cakes are not only pressed into the conveyor by the drive and chopping shaft, but are also largely crushed at the same time, jams at later transfer points to other conveyors cannot occur.

The drive and cutting shaft can have radially arranged drive arms and cutting arms, which are arranged alternately offset from one another by 90 ° in the longitudinal direction of the shaft. Hierdurr-h \ i ± vd achieves a spiral-like way of working, which is very even, bump-free

operation enabled and an even supply qcg r'ürce flutes in the trough chain conveyor;:; ev; uiirriegel'c.

According to the invention, in Föraerricntung de ^ TrocKe'c conveyor before the driving and Zerschneidev. ^R elle a rake can be arranged, the prongs of which reach down approximately to the height of the shaft and between which the drive arms and cutting arms of the shaft reach through the drift and snow level turns.

According to the invention, the rake is square in the plane the front wall of the bunker on the outlet side is arranged irio the driving and cutting shaft is in a special, Send to the front wall of the bunker, from outside sen housed accessible housing. This refinement; makes it possible to use the entire length of the bunker as a collecting and to use federal space. Besides that. can the driving and The cutting shaft can be easily cleaned, replaced and repaired without having to open the bunker and be The discharge funnel must be emptied.

The invention is illustrated by the drawing using an exemplary embodiment explained in more detail. It shows:

is derived. Any water that has backed up is caught by a second, slightly higher drain 17 and discharged through a second discharge pipe 18.

The conveyed goods falling into the upper trough 13b are discharged from the upper run 19 of the conveyor in the direction of the arrow and dropped into a hopper at the front reversing station 20, from where it is transported further in some way will. The drive 22 for the trough chain conveyor is located at the front reversing station

On the outlet-side end wall 23 of the bunker 11 is an opening extending over the entire width of the bunker 24 arranged, which is partially closed in the upper part by a rake 25. The tines 26 of the rake extend approximately to the height of the shaft 27 of a drive and cutting shaft 28, which is immediately above of the trough chain conveyor 13 is arranged in the area of the outlet-side end wall 23 of the bunker 11, and is transverse extends to the trough chain conveyor. The drive and cutting shaft carries several radially arranged drive arms 29 and cutting arms 30, which are arranged alternately in the longitudinal direction of the shaft and offset from one another by 90 ° are (Fig. 2). When the shaft 27 rotates, the drive and cutting arms engage between the prongs 26 of the Rake 25 through it, shred the material to be conveyed and press it from above into the trough chain conveyor. For this purpose

the driving and dissolving wave turns in the in 1 shown in the counterclockwise direction in the direction of arrow 31.

In order to be able to easily cut the conveyed material, the cutting arms 30 are provided with cutting knives 1) 2 bent back in the direction of rotation. provided, dij allow a pulling cut. The drive arms 29 carry plates 33 at their free ends which extend radially and transversely to the direction of rotation of the shaft 2? extend.

As can be seen from FIG. 1, the drive and cutting shaft is arranged in a special housing 34 which adjoins the end wall 23 of the bunker 11 on the outlet side. This housing 34- has a closable opening J> b, through which the housing 34 is accessible and the drive and cutting shaft can be cleaned or removed and repaired. The drive 36 of the drive and cutting shaft is located outside on the side of the housing
