Description

Control nests, also known as trap nests, are known to be used to determine the laying performance of chickens. The desire to mechanize the time-consuming work of trap nest control ζμ- has led to that a number of automatically operating nests have been constructed. Such a thing After laying eggs, Nest releases the chicken through a second exit opening into another stall compartment and thereby separates the hens that have laid from * those who have not laid - but their construction is very complicated. The invention has a simpler one Construction that enables a safer operation to be achieved.

Using the drawings, the method of operation is described as follows, with the structure of the Nest from Figs. 1 and 2 results.

The hen enters the nest via the lid 5 of the egg box 10, which also serves as an approach board. It first opens the first flap 3, which is mounted horizontally in a known form and swings back and forth in the starting position. The hen crosses the fixed bridge 4, which has the corresponding through openings for the approaches of the camshaft and locking bolt, and enters the actual nest 2. The bottom of the nest falls forward and has a through opening a through which the egg is deposited in the direction of the arrow unrolls. The nest 2 can swing about a lateral axis and rests on the other side on the shorter arm of a two-armed lever, which is designed as a locking bolt 11. The longer arm of the locking bolt 11 is so heavily weighted that the empty nest is lifted by it, and it has an upwardly projecting extension 8 which comes through the fixed bridge 4 behind the first flap 3. Under the weight of the hen's body, the nest 2 lowers, whereby the locking bolt 11 comes into action; the first flap 3 can now no longer be opened to the rear, so that no second hen can enter the nest.

If the eggs are not laid, the hen can leave the nest again through the first flap 3, by opening it to the front. As soon as the nest 2 is empty, the locking bolt 11 falls by its own weight down and lifts the empty nest 2, the first flap 3 swings again in both directions.

Under the nest 2 there is another two-armed lever 1, one arm of which is designed as a catch 9 for the egg and is lifted under the through opening α by the barrel weight 16 on the other arm of the lever. By means of the barrel weight 16, the two-armed lever 1 can be adjusted so that it does not respond to eggs that are below a certain weight limit.

In addition to its storage, the lever 1 has a

angular extension 13 on which the angled extension 12 of the camshaft 7 rests. The camshaft 7 is under the lateral pulling action of the spring 17 and has the further approach 19, which is in the starting position stands vertically upwards, reaches behind the second flap 20 and locks it. The second Flap 20 is designed like the first flap 3, but can only be opened to the rear.

The camshaft 7 has a double approach 6 at the front, one part in front of it, the other part behind the first flap 3 engages. In the starting position, the double approach 6 is about 40 ° from the vertical Position deviating, laterally, so does not affect the flap 3.

As soon as an egg falls on the catcher 9, the lever 1 tilts; as a result, the approach 12 slides Camshaft 7 from the angular extension 13 of the lever 1. The camshaft 7 thereby loses the Stop and is rotated by the spring 17 by about 40 °; now there is the double shoulder 6 of the camshaft 7 vertically upwards and locks the flap 3 in both directions; the approach 19 of the The camshaft 7 is to the side so that the flap 20 is no longer locked. The hen can after the Only leave the nest through flap 20 for laying eggs.

When the hen leaves the nest through the flap 20, she walks over the footboard 18. The footboard 18 represents one arm of a two-armed lever, the other arm is under the action of a spring 15 and has an extension 14 which engages under the extension 12 of the camshaft 7. Due to the pulling action of the Spring 15, the footboard 18 is raised. When the footboard 18 is depressed by the weight of the hen the shoulder 14 of the footboard rotates by lifting the shoulder 12 of the camshaft 7

this back to the starting position. This unlocks the flap 3 and locks the flap 20; the locking bolt 11 falls down and lifts the empty nest 2. The automatic control nest can be entered by a second hen.
