Round silo with pneumatic removal device. ·,

The invention relates to a pneumatic extraction device according to the preamble of claim ί. .

In the case of the above-mentioned pneumatic extraction devices, the type of conveyor disks or the like of the rotating type is known Radial arms conveyed from the outside to the inside to the suction mouth «Silage is pneumatically sucked in and conveyed away, however, the silage is not picked up by the suction mouth in the area of the surface part bordered by the surrounding suction mouth and promoted if it is relatively long Fibrous silage is involved, which is firmly hooked to the underlying silage, so that it is through the negative pressure Pneumatic alone cannot be sucked in in the suction mouth. In practice, therefore, the procedure was that for the silage within of the circle of conveying devices described by the rotating suction mouth, e.g. »Conveyor disks attached to the radial arms that the Sila.ge from the middle of the silo to the circumference of the Promote suction mouth described circle so that it can be loosened pneumatically here.

-A-

The object of the invention is to remove the material that is not conveyed sufficiently evenly from the outside to the inside to the suction mouth is not completely picked up by the suction mouth and remains, to be brought back into the product surface or over the product surface to distribute evenly in order to block blockages in the conveyor pipe by other unevenly distributed goods avoid and prepare the silage located within the conveyor mouth turning circle in such a way that they are pneumatically removed from this area can be removed from the suction mouth. It should also be achieved that any long dragging parts hanging out of the suction mouth Straws are pulled out of the suction mouth.

This object is achieved according to the invention by the characterizing features of claim 1.

The spiked roller, which is driven by a disc that engages the silage with circumferential teeth or a universal pin, and which can also be provided with an external drive, distributes too much remaining silage over the surface again over the surface and otherwise loosens the silage surface in the middle area in question that the silage readily that also receives the power supplied by the external of the circuit conveyor discs silage _r entrained by the air flowing into the air far Saucjmund conveyor on. It is. thus the arrangement of other conveying organs or conveying devices from the central axis to that described by the suction mouth

Promote circulation circuit, superfluous, especially since it is considerable constructive Difficulties are caused by such conveying organs or conveying disks within the central area with a relatively small To accommodate a radius that cannot be increased as desired without disadvantages, since blockages in the delivery pipe then occur can occur in the event of a fall.

The invention is explained below with reference to the drawing, in which an embodiment is shown. Show it:

Figure 1 is a horizontal schematic section through a round silo with which the silage to a suction mouth pneumatic suction system promoting organs and the arrangement of the spiked roller according to the invention,

FIG. 2 is a partial side view, seen in the direction of arrow X in FIG.

According to the invention is in a known manner centrally in a round silo 1 from top to bottom an expandable and Collapsible telescopic tube introduced, which is connected to a suction-pressure fan. The telescopic tube is at the lower end with a rotatable about the silo axis or telescopic tube axis, angled or cranked to the axis Suction trunk 2 provided with suction mouth 3. For removing silage from the silo, the silage is passed through the silage surface Conveyor organs fed from the outside to the inside ^ n the suction mouth 3, where it is pneumatically picked up and conveyed away.

The conveying elements consist, for example, of wheels or discs with teeth or pegs 4a provided on the circumference, which are driven to rotate together with the suction mouth 3 on radial Support arms 5 are freely rotatable and have an angle of attack to the direction of rotation. By intervention of the original catch in the silage and the angle of attack, these rotating discs, rotating around the silo axis, gradually convey the silage to the suction mouth 3 as it is known.

To now, within the circulation circuit described by the suction mouth 3, the silage through the suction nozzle 2 with suction mouth 3 as well to be able to remove and convey away is according to the invention in the direction of rotation behind the trunk 2 between the silo axis and the turning circle described by the suction mouth 3 has a spiked roller 6 with a horizontal, radial or approximately radial axis on one the support arms 5 are freely rotatable. This spiked roller b can be cylindrical or frustoconical and is provided on the outer end face with a disk 7, the diameter of which is greater than that of the roller 6 and the circumference thereof Teeth or pins to engage in the silage is equipped. This disk 7 forms the drive disk for the spiked roller 6, which loosens the silage within the circle described by the suction mouth 3 in such a way that it is absorbed by the flow of conveying air and can be conveyed away pneumatically.

^{the spiked roller 6} is designed in the shape of a truncated cone, the smaller end face being directed towards the silo axis. Due to the truncated cone formation, any stalks that curl up on the roller fall off the roller again.

The spiked roller 6 can also be set in rotation by an external drive, e.g. in that one of the Support arms 5 a toothed on the circumference, tangential to the orbit and the drive wheel engaging in the silage is mounted, which drives the spiked roller through a transmission gear 6 drives. This makes it possible to increase the speed of the spiked roller.

Finally, it is possible according to the invention to additionally place a finger star behind the spiked roller 6 around one to the perpendicular to store inclined axis freely rotating, whose fingers with their ends also into the silage to their further Loosening intervening.
