Description

Poultry egg incubator.

Field of the Invention

The object of the present invention relates to a bird egg incubator, mainly chicken eggs, without ruling out those of other species, this incubator being Automatic operation with multi-parameter control of treatment.

Background of the invention

Incubators of this class are usually constituted by an open chamber with two opposite ends, inside which chamber is a belt or conveyor belt on which the eggs are arranged by one end or entrance to said camera; motor means produce the slow advance of said band with the cited eggs (with a regular progress day by day) and after of a certain time, by the opposite end of the same band, chicks come out after hatching the corresponding ones eggs

To favor the aforementioned incubation, during certain environmental conditions must intervene, for which said chamber is usually equipped with heating means, humidifying means and light emitting means.

Documents are already known, for example, the DE 3900012, which deal with incubators as a camera equipped with a egg conveyor belt, even with heating means and humidifiers, as in GB 170.1652.

Apart from these climatic conditions, which they occur in natural incubation, there is another condition. Indeed, For some time now, scholars on this subject realized that during incubation eggs must be moved or changed periodically position, at least for a certain time, in order that the embryo does not stick to the inside of the shell which It would spoil the future chick. In the natural incubation this movement also instinctively, the same chicken; in artificial incubators it was done manually by poultry farmer, which was still a very burdensome task, and currently said movement of the eggs is carried out with means mechanics, such as probes, brushes, staples or equivalent, however, the variation of position of the eggs by means of said mechanical means, in addition to the complexity inherent in its assembly and adequate control (and subsequent associated construction cost), has the inconvenience of not being completely reliable: there is always some left egg that has not been moved or conveniently moved to the detriment of the correct incubator progress thereof.

Exhibition of the invention

The bird egg incubator proposed by the The present invention is composed of a tunnel-like camera, open at two opposite ends, where it has paths doors defining an entry end and an exit end, having inside a chamber a structure endless belt conveyor mounted between two pairs of chain wheels: a pair of driven drive wheels by a motor and a pair of driven wheels; which structure transportadora is endowed with a plurality of accommodations transversal for rows of eggs that transports them, with advances very short distance, from the mentioned entrance to the exit where there is a tray of hatched eggs, being characteristic that said transverse housings are devoid of substance and consist of a series of bars parallel to each other and transverse to the structure itself, connected to the links of openwork chains in the aforementioned chain wheels, with the particularity that under a first area of the upper section of the conveyor structure Endless, from the entry end, there is a fixed platform on which the eggs pass and when pushed by the respective bar are forced to roll by turning continued during its advance towards the exit end, and because to then there is a second zone of the same upper section of the conveyor structure, prior to the receiving tray, in which below the same band is a circulating tape endlessly experiencing the same speed of advance that the conveyor belt with what the eggs when entering in said second zone they are carried on said circulating belt towards the exit end without experiencing any turning.

The displacement of the structure transporter is slow and in general the treatment includes some advances and setbacks, from time to time, originating each of said displacements a turn of the eggs a certain angle, at least 90 degrees, and subsequently, at the end of each day It produces an effective advance of each row of eggs towards the exit. To ensure these advances and setbacks the engine is equipped with a control equipment for example a servomotor.

The length of the said first zone of the Conveyor belt and fixed platform corresponds, according to the effective displacement of advance of the conveyor structure, to a time of incubation in which the eggs must be turned every certain period of time

Instead, the length of the said second zone of the conveyor structure and top of the belt Endless circulator corresponds, according to this advance effective, daily of the endless conveyor structure, to a incubation time when eggs should no longer be turned around

It is evident that with the present invention the egg turning procedure is greatly simplified during incubation, while ensuring that all of them participate in a regular manner of said essential turning.

These and other features will become apparent. in the description that follows.

Brief description of the drawings

In order to facilitate the understanding of the explanation that follows later, some drawings are attached in the that:

Figure 1 schematizes a sectional view length of an incubator according to the present invention.

And figures 2 and 3 are sections transversal, partial, of the same incubator carried out by the cutting planes II-II and III-III of Figure 1 respectively.

Detailed description of a preferred embodiment of the invention

According to the cited figure, the incubator that proposes it consists of a tunnel-like camera 1 with a input end 2 and an output end 3 provided with respective doors, within which chamber 1 is located a Endless belt structure 4, conveyor of eggs 5a, 5b installed between two pairs of chain wheels, one of them 9 driven by a servomotor (not visible) and the other driven 12, The conveyor structure 4 carries the eggs to incubate from said input 2 to output 3 of chamber 1, heating means being provided within said chamber, media that impart moisture inside it and media light emitters that have not been represented so as not to recharge the drawings and because, in addition, they are all of the conventional type.

According to the present invention said structure conveyor 4, endless is materialized by a series of bars 14, parallel to each other and transverse. Those cited bars 14 of structure 4, conveyor define about bottomless housings 16, the ends of said being joined bars 14 to the respective endless chain 7 mounted on those pairs of chain wheels 9 and 12. The function of said bars 14 is double: procure said housing for rows of eggs 5a, 5b separating one from another consecutive row and push said rows of eggs towards exit 3 of chamber 1 5a, 5b. The distance between the bars is such that it allows the eggs can rotate in the space they delimit, as will be seen in the explanation that follows.

In the case of chicken eggs, the period total incubation, that is, since each egg is disposed in the chamber 2 input until a respective chick has hatched and exits through exit 3 of the chamber, it is estimated at about twenty one days However, this period must be subdivided into two: a first period of about eighteen days in which the 5th eggs they must be moved or turned from time to time to avoid sticking from the embryo to the inside of the shell, as already mentioned principle, and during which the same 5th eggs should receive a certain temperature and a certain degree of humidity; and a second period in which 5b eggs should no longer be turned and should receive another temperature and a different degree of humidity. The areas where different degrees of heat and humidity must be observed They are separated by a curtain (not illustrated). It is also foreseen a third area, also separated by a curtain, where they are Chicks delivered and that is at another temperature and humidity.

Also, in the transport structure itself 4 there are two zones "A" and "B". Indeed, it is important in the present invention that to achieve this differentiation of flipping and non-flipping of the eggs during their advance Inside the incubator chamber 1, a first area of the conveyor structure 4 in which under a first section "A" thereof, corresponding to the length that the structure 4, bearing the eggs it travels (movements in advance, effective, daily) for eighteen days (according to the same course of chicken eggs) there is a fixed platform 17.

Equally important is that following said first section of the conveyor structure there is a second section "B", equivalent to the length of the route itself structure 4 during the remaining three days of incubation, endowed of an endless treadmill 18 mounted between a drum 20 attached to the same axis 22 of the driving wheel pair 9 and a crazy roller 24 thus participating, said circulating belt 18 of the same forward speed as the cited bars 14. Said belt 18 It has substantially a width equal to the length of those pusher bars 14.

With such an arrangement, during your tour initial corresponding to zone "A" the 5th eggs are pushed laterally by the respective bar 14 with the result that, when moving on that fixed platform 17, the same 5th eggs do not slide on it but roll on it fixed platform making a slow and steady turn around your axis length during said first travel.

Instead, when eggs 5b enter the second zone "B" of the conveyor structure 4 the same they go to rest on the endless treadmill 18 participating in the same forward or reverse speed as the pusher bars 14 and therefore, said eggs 5b neither slide nor they roll: they are relatively motionless with respect to their axis longitudinal.

As indicated by the incubator, in operation imposes several advance cycles over a day and recoil, of equal amplitude, and very short development, ending For an effective advance.

To achieve this operation, an engine is used servo-controlled that provides the aforementioned structure 4 several forward-reverse cycles spaced throughout the day, ending with an effective advance per day, so that the 5th eggs being pushed by the Bottom 16 housing walls, are forced to roll over the fixed platform 17 performing a turn with an amplitude of at least 90 degrees, during each forward or reverse movement, while the eggs resting on the circulating tape Endless 18, experiencing the same speed of forward or reverse that the conveyor structure 4, do not suffer I turn some.

Near the open end of exit 3 of the incubator there is a collection tray 26 where the conveyor structure 4 throwing on it the chicks 5c that They have already hatched. Advantageously said tray 26 is coated on its reception face with a layer of fluffy material 28, such as plush or similar and the immediate area is another temperature and humidity to dry the chick 5c separated by another curtain from the rest of the incubator.

A subject matter expert could introduce changes and modifications in the described embodiment example, without depart from the scope of the invention, as defined in the attached claims.
