Description

The invention relates to a device for Obeneütnahae of the content, b.B * green fodder, of silos, with a das Well-releasing conveying means that work from the edge of the silo to the center, the material is a motor-driven ejector, s ^ jft, a | a blower »supplies,

So far, the detached conveyed goods have been removed from the top discharge devices given up to the fan in its direction of rotation " Vöbei the fan axis and the drive axis of the conveyor, s.B. a clearing chain, run parallel *

With this type of assignment of fan axis and "SinvaLrfrichtung" have "in practice decisive disadvantages set.

Furthermore, in the case of "heavy goods" only a part * of the tangential from the conveyor links of the chain hurled good from the impellers v / earthed, while the other part hits the casing and falls out downwards.

In the case of the known top-taking devices, the fan and the clearing chain are immediately shut down ^{with 1} the ^ b- ^{fc * switching of the motor.} The goods thrown into the blower at this point in time remain, unless they are nafcö

falls out at the bottom, on the impellers, on the clearing chain often lie and can in the corners of the casing Bake together with the appropriate consistency. This fact repeatedly led to teething problems when the device is started up again.

The invention effectively avoids these disadvantages in that the blower axis runs approximately in the direction of the conveyed goods and the blower housing has a suction opening in the axial direction into which the conveyed goods are thrown by the conveying means ¹ .

In a preferred embodiment, the fan is with respect to of the putter level at about the same height as the funding arranged and provided with a funnel on the suction side, the smallest diameter of which is smaller than the Impeller diameter of the fan is dimensioned ·. "~" ■■■■■■ ■ '· - ·. '■. ■

When using a clearing chain as a means of conveyance, the ' Fan axis advantageously perpendicular to the front the drive axle of the clearing chain lying next to the hopper arranged and the drop end of the chain brought up to or into the hopper. -

This type of arrangement has several advantages. Since the blower and discharge side of the chain are next to each other, the goods do not have to, v; ie previously, from. following the chain
