of the outlet is bent outwards.

Patented in the German Empire on October 7, 1910.

When filling material from silos, containers and the like, the disadvantage is often that the outflow of the material cannot be completely prevented because when closing of the silos larger pieces to lie between the flaps and the discharge end come so · that the flaps-not quite can close and therefore fine-grained material falls. This material falls when the transport trolley moved away and a new one has not yet been placed under the outlet is on the ground and the track and must be removed from time to time.

The previously known closures of such discharge devices are also closure flaps with larger weights required, which 'take up a relatively large amount of space and, for example, in the case of double silos an offset arrangement of the closures to one another or the arrangement of the closures at greater distances from each other. A simultaneous filling of two or more Closures in one and the same trolley is therefore with such facilities not possible.

The present invention relates to a spout closure for silos, containers, etc., where larger pieces of material are jammed between the flap and the outlet end prevented and a Safe leakage of the material with the shutter open is achieved by worry is responsible for the fact that constipations in the Cannot enter the run-out. This happens because the approximately perpendicular standing front wall formed by the rest of the walls converging at an angle Outlet at the point at which the outlet has the smallest cross-section is bent on the outside, so that the leaking good from this point onwards is getting bigger and bigger Has to pass cross-sections, which prevents the material from arching will.

According to the invention, in a sol-

Through such a transverse wall that braces the side walls the resistance increases, and, as part of the material pressure from the bulkhead is recorded, and the flap both in the closed state and in particular at the beginning of closing relieved. In addition, through this transverse wall, the flowing out of the outlet is also created Material flow pushed down. The latter two circumstances cause the when closing the spout due to its own weight falling shutter at Hitting the stream of material has already acquired sufficient vital force to to cut through the flow of material with its leading edge • with certainty, thereby creating a

Jamming of pieces of material between the outlet end and the flap is avoided will.

In the drawing, an embodiment of the subject matter of the invention is shown.

Fig. Ι shows the closure in vertical section. A reverse arrangement of the The outlet is here with dotted lines

ίο indicated. Fig. 2 is a view in the direction of of the arrow I of FIG. 1 seen. Of the two flaps of the spout is one closed and the other omitted to represent the interior to be able to. Fig. 3 is. a top view of the spout.

The silo has above the spout by the three walls A, B, C a funnel-shaped rectangular cross-section tapering to a horizontal plane a, b, c, d, while the fourth front wall D is almost perpendicular from the horizontal. The hopper wall A ₁ which forms a slide is extended at 45 ° from the horizontal and downwardly inclined. On both sides of the sliding wall A , the walls E and F stand vertically, the lower edges e, f, g of which are curved around the axis of rotation G. The front end is formed by the elongated, outwardly curved wall D, which ends at e , and by a Quenvand L at /. The latter is used to support the flaps and to partially relieve them of the material pressure.

.A possible formation of vaults in the dangerous cross-section /; and underneath, which would carry the material in the discharge funnel and thereby prevent it from running out, is through the appropriately selected cross-section Λ, through the radially outwardly curved, almost vertical wall D, and 4 <> the one between the transverse walls D and L. Prevented a gap in the front wall, which means that interference during the run-out is excluded.

The closure is produced by a radially curved flap K , which can also be replaced by several flaps arranged next to one another. The flap K rotates around a shaft mounted at G and is curved around the axis of rotation, so that when it closes it cuts through the outlet flow without forcing material back into the outlet.

The purpose of arranging several flaps next to each other is to keep the goods to be drained in to be able to drain any amount.

The shutter is opened by lifting the flaps using a winch device, closing by dropping the flaps.

Claims (1)

Patent claim: Outlet closure for silos, containers, storage rooms, etc., in which the front wall of the outlet is bent outwards, characterized in that the Front wall stops shortly after the turn and at a certain distance from the lower edge of the front wall a spans the two vertical side walls-η end, in front of the mouth of the outlet and, if the outlet is closed, within the closing flap lying transverse wall is arranged, which the closing flap relieved when closing and in the closed position. 1 sheet of drawings.
