  • the screw conveyor 42 may be fixed in position at the front end region, in particular at the angle gear 45 and at the rear end region, in particular in the region of the conveying channel 43.
  • the pitch of the screw surface may increase from the forward end portion of the auger 42 towards the rear end portion of the auger 42, which can be promoted reliably and without clogging the Rlickwerksaustragung 4 even when a trituration of the stored material.
  • the screw conveyor 42 may be formed conical or frusto-conical and so the screw conveyor 42 may have a continuous, varying outer diameter, wherein the diameter of the central shaft along the longitudinal extent of the screw conveyor 42 may be formed substantially constant or varying.
  • the screw conveyor 42 is arranged exposed in the silo 1, wherein the silo 1 is channel-free and substantially flat.
  • Particularly advantageous has shown in the Rlickwerksaustragung 4 that granular and / or hackschnitzelförmiges stored goods reliably with the exposed in the silo 1 screw conveyor 42 - like this in Fig. 1 to 5 is presented - promoted, so discharged, can be.
  • the screw conveyor 42 is not disposed within the silo 1 within a channel, but is free in the silo 1. In this way, the silo 1 without a channel for receiving the screw conveyor 42, that is channel-free, formed, so that the dead space in the silo 1 and the cost of the silo 1 can be low.
  • the screw conveyor 42 can rotate freely in the stored product. The advantage here is that - due to the lack of the channel in the interior of the silo 1 - too much of the screw conveyor 42 detected and / or promoted stored goods can slide sideways and / or upwards.
  • the advantage here is that the screw conveyor 42 does not have to be tuned to a channel, with which a standardized embodiment of the screw conveyor 42 for different geometries and different sizes of the silo 1 may be suitable. As a result, a standardized screw conveyor 42 on-site can be cut to the required length and installed. As a result, expensive individual productions of the screw conveyors 42 can be avoided, as well as the production costs and the production costs of the silo 1 can be reduced. In particular, it can be provided that the feed screw 42 can be cut to length as an on-site Standard screw conveyor is formed. The advantage here is that it can be dispensed with individual productions of screw conveyors 42 and thus the cost of production are low.
  • the conveyor screw 42 designed as a standard screw conveyor can be delivered to the destination with a predetermined excess length and that it can be cut to length on-site.
  • deviations of the actual silo dimensions from the planned silo dimensions can be compensated, and thus it can be prevented that a conveyor screw 42 prefabricated with a planned length can subsequently be reworked, length-corrected or replaced.
  • the silo shell 3 - as in Fig. 2 shown - be formed substantially round and the silo 1 may comprise four housing supports.
  • embodiments of the silo 1 this - seen in the view from above - also be oval or polygonal, in particular triangular, hexagonal or octagonal.
  • the maximum area 411 which can be painted over by means of the agitator arm 41 is substantially only slightly smaller than an inner circle of the silo bottom 11.
  • the area not covered by the stirrer 9 - at its rotation about the main axis of rotation - can be small.
  • An advantageous direction of rotation 412 of the agitator arm 41, in particular of the two agitator arms 41, is also in Fig. 2 shown.
  • the maximum coatable surface of the agitator arm 42 can be larger than the inner circle of the silo bottom 11. In this way, it can be ensured that the agitator arm 42 can also extend into corners of the silo 1 during its movement-in particular slowly-and can also ensure the emptying of the silo 1 there. As a result, the usable volume for the user, ie the net silo volume, can be made particularly high.
  • the agitator arm 42 may be formed with a flexible free Rlickwerksarmspitze, which has a particularly high deformability. It can thus be ensured that the silo shell 3 is essentially permanently touched by this agitator arm tip, whereby due to the flexibility of the flexible free agitator arm tip it can be provided that the silo shell 3 is not damaged by the agitator arm tip.
  • This can be ensured in an advantageous embodiment of the Rlickwerksarmes 42 by a combination of the spring leaf and the spring-actuated articulated arm, wherein the free Rlickwerksarmspitze, which forms a free end of the Rntontechnikarmes 42, instead of steel and a plastic, in particular a thermoplastic and / or an elastomer may be formed.
  • the at least one agitator arm 42 is designed to minimize friction, in particular as a sliding surface, preferably as a roller mounted so as to be pivotable essentially about the perpendicular, at its free end, in particular on the free agitator arm tip.
  • the abrasion of the silo shell 3 with rotating agitator arm 42 can be particularly low.
  • the advantage here is that while little friction occurs and thus the load of the agitator 9 and the drive of the agitator 9 can be low. In particular, the necessary drive power of the agitator 9 can be kept low.
  • the agitator 9 used may further comprise a central agitator cover 44, which in the region of the main axis of rotation and - seen in the position of use of Rlickwerksaustragung 4 - can be formed above the bevel gear 45.
  • the agitator cover 44 prevent ingress of stored goods in the angular gear 45, whereby the angle gear 45 can be formed in particular substantially maintenance-free.
