DESCRIPTION:
BRIEF SUMMARY
The object of the present invention is to provide equipment by which feed can be dispensed automatically and continuously into the feeding-troughs of batteries of cages on several levels, for poultry keeping, in particular for laying hens or also for other types of rearing.
It is known, particularly in laying hen instalations, that they have to be provided with very regular and constant feed, though it must be possible to adjust the quantity on the basis of the growth of the animals being reared.
It is known, that a present feed is dispensed into the feeding-troughs of batteries of cages on one or several levels by means of equipiment that does not allow uniform dispensing of the feed, which is greatly prejudicial to the results obtained.
With the use of the equipment in accordance with the invention, however, the feed is dispensed automatically and continuously along each row of feeding-troughs, breaking off in the gap between one row and the next and resuming along the adjoining row of feeding-troughs, until dispensing is finished on a specific level.
Next, when the dispensing screw has been transferred to the following level, e.g. the level below, feed is dispensed into the feeding-troughs on this next level and the whole operation is thus repeated until all levels of feeding-troughs have been supplied.
One of the essential characteristics of the equipment is due to the fact that the quantity of feed to be dispensed is adjusted by altering the rate of advance of the screw previously located on the bottom of the dispenser.
An essential characteristic of the device is the face that the feed is dispensed with complete uniformity into all the feeding-troughs and at each level, in the required quantity and in a manner entirely adjustable at will.
The invention will now be described in greater detail with the help of the attached plates of drawings, in which:
FIG. 1 shows a diagrammatical front view of a battery of cages, with the equipment according to the invention mounted on it;
FIG. 2 shows a diagrammatical top planar view of the equipment for supplying a series of batteries of cages;
FIG. 3 shows a side view, in partial section, of the dispensing device with a rotating screw.
The equipment according to the invention comprises a dispensing hopper 1 (FIG. 1), mounted on a mobile chain 2, which makes it possible to locate it at the required height on the supporting upright 3.
The latter is mobile on the bottom tubular rail 4, on which the shaped rollers 5 rest, while at the top it can slide on the tubular rail 6, this, too, being fixed to the framework bearing the cages, while shaped roller 7 rotates on a vertical pin fixed to an arm projecting from upright 3, while roller 8, equipped with a driving motor 9, moves the upright 3 along the side of the framework bearing the cages. The shaped roller 7 is advantageously fixed elastically to the framework via spiral spring 10, so as to provide elastic adherence between roller 8 and rail 6.
FIG. 2 shows the planimetric course of rail 6, which alternating course is fixed along both sides of each battery of cages, indicated diagrammatically in the drawing by the numerals 11, 12 and 13.
During the travel of hopper 1, in unloads the feed exclusively in the rectilinear sections corresponding to each battery of cages, in order to tip the predetermined quantity of feed into the feeding-troughs, along these stretches only.
The dispensing screw is therefore fitted with a closing device which operates automatically, touching a stop component 22, in correspondence with each rectilinear stretch, to remain motionless, due to the stopping of the motor, in the ensuing curved stretch and start again on the next rectilinear stretch.
At the end of one passage along all the batteries of cages, e.g. on the first level, the driving motor of the chain 2 (FIG. 1) comes into operation automatically and lowers hopper 1, so as to bring it to the level of the next feeding-troughs, after which the travel to supply this second level starts, along which the dispensing screw returns to point 14
