Definitions
- the present invention relates to improvements to silo emptying devices.
- This device consists of hollow ribs arranged on the bottom of the silo, said ribs being joined by perforated plates constituting the bottom of buckets, the sides of which are formed by the sides of the ribs.
- Each rib has orifices opening out under the perforated plates, means being provided for sending pressurized air into the passage formed by each of the ribs.
- the object of the invention is to provide a drainage device using ribs of a known type, that is to say made of corrugated sheet metal, bent in the form of a tunnel, so as to obtain all the advantages inherent in this type of rib without having the disadvantages.
- the base of the usual troughs is formed by profiles with trapezoidal section, fixed on the bottom of the silo and the lateral wings of which are flared outwards, the internal face of each wing being covered by the edge of the tunnel corrugated iron, the latter being judiciously cut to form flaps allowing the air circulating under the tunnels to enter the buckets and to advance the grain contained in the latter, the seal between the buckets and the tunnels being obtained by a cement bed deposited on the bottom of said profiles.
- tunnels 2 made of a corrugated and curved sheet, each providing between its internal face and said bottom 1 a corridor 3 in which we send air.
- trapezoidal section profiles made of folded sheet metal for example, are fixed to the bottom 1 of the silo, the bottom 4 of which is fixed against the said bottom 1 and the wings 5 of which flare outwards.
- each tunnel is cut according to two incisions, one of which 6 extends parallel to the corrugations of the sheet and the second 7 of which extends perpendicular to the first, substantially up to the top of the corresponding corrugation, the part thus cut being raised to form a flap 8 ( Figure 1).
- the lateral part 9 of each tunnel is fixed, by any usual means, against the internal face 5a of the wing 5 of the trapezoidal profiles.
- a bed of cement 11, or the like, extending in height, is placed on the bottom of the trapezoidal profiles, at least, up to the lower corner 8a of the flaps 8.
- the air flowing in the corridors 3 enters the troughs 10, through the openings formed by the flaps 8, in a direction which extends substantially parallel to the axis of said troughs.
- the wings 5 extend in height, well above the upper angle 8b of the flaps 8. In this way, the flaps 8 can provide outlet openings air having a relatively large section without risk of grain penetrating into the corridors 3.
