[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage cage for egg collection.

[0002]

2. Description of the Related Art In conventional multistage cages for egg collection,
As shown in FIG. 6, the upper cage 1 and the lower cage 2 are deeply stacked to reduce the area occupied by the site. However, when the upper and lower cages 1 and 2 are deeply stacked, chicken droppings in the upper cage 1 are caught on the chickens in the lower cage. Therefore, conventionally, as shown in FIG. Bottom net 1
The vinyl sheet 5 as shown in FIG.

Further, in the above-mentioned slanted ceiling net 3, the horizontal wire 3a at the uppermost end thereof, as shown in FIG.
The upper cage 1 was reinforced by supporting the entire vertical wire in the bottom net 1a of the upper cage 1 with the horizontal wire 3a.

[0004]

In the prior art, the bottom wire 1b of the bottom net 1a of the upper cage as shown in FIG. Abut.

Therefore, due to the load of the chicken in the upper cage 1, the bottom net 1a bends around the wire 3a as a fulcrum as shown by the chain line A in FIG. As shown in FIG. 5, the egg 4 rolling on the bottom net 1a in front of the cage is stagnated at the wire 3a portion, causing a problem of soiled eggs and broken eggs.

The present invention prevents such stagnation of eggs,
The purpose is to prevent dirty eggs and egg breakage.

[0007]

In order to solve the above-mentioned problems, the present invention has a bottom net (1a) in an upper cage (1).
In which the front lower surface of the above is supported by the upper end of the slant ceiling net (3) of the lower cage (2), upward convex portions (3b) are provided on both sides of the upper end of the slant ceiling net (3). The part (3b) supports both sides of the bottom net (1a) in the upper cage (1), and the middle part of the bottom net (1a) is not supported by the slant ceiling net (3). is there.

[0008]

[Function] In the bottom net (1a) of the upper cage (1), the vertical wire (1b) in the middle portion through which the laid eggs pass
Since its lower surface is not supported by the slant ceiling net (3), it bends around the front wall net of the cage (1) as a fulcrum.
Therefore, even if the flexible shape is plastically deformed, the egg does not stay in the middle of the bottom net (1a) and rolls to the egg receiving portion 1d formed in the front portion and is discharged.

Further, the reinforcement of the upper cage (1) by the slant ceiling net (3) is sufficient only by supporting both sides of the bottom net (1a).

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in FIGS. 1 to 4 will be described. Reference numeral 1 is an upper cage, and 2 is a lower cage, which are held at predetermined positions by columns 6 and beams 7, respectively. The bottom net 1a of each cage 1 and 2 has a plane shape as shown in FIG. 4 and is formed of a large number of horizontal wire 1c.
An egg receiving portion 1d is formed in the front portion and is installed in the front downhill as shown in FIG.

Reference numeral 3 denotes a slanted ceiling net which constitutes a rear portion of the lower cage 2, and an upper portion of which projects above the ceiling net 2a of the lower cage 2. Further, on both sides of the upper end of the slant ceiling net 3, there are formed convex portions 3b projecting upward from the intermediate portion.

That is, the uppermost horizontal wire rods 3a, 3a on both sides are made short and only this supports the lower surface of the vertical wire rods 1b 'on both sides of the bottom net 1a of the upper cage 1, and the other bottoms. Vertical wire 1b in the middle of the net 1a
A predetermined gap D is provided between the upper horizontal wire 3c of the slant ceiling net 3 and the vertical wire 1b in the middle portion is not supported by the slant ceiling net 3. The vertical wire 1b 'and the horizontal wire 3a on both sides are connected to each other by sealing or the like.

Reference numeral 8 in the figure is an egg guard. 5 is a vinyl sheet hung on the slanted ceiling net 3 in the lower cage 2,
This is to prevent feces from chickens in the upper cage 1 from falling into the lower cage 2.

The upper cage 1 and the lower cage 2 are shown as one each, but these cages are arranged in multiple stages in the vertical direction and are continuously arranged in the horizontal direction.

With the above-mentioned structure, the vertical wire bars 1b 'and 1b' at both end portions of the bottom net 1a of the upper cage 1 are supported by the convex portions 3b formed on the slant ceiling net 3 of the lower cage 2. It Therefore, when the bottom net 1a is bent by the load of the chicken, the vertical wire 1b ', 1b' bends as shown by the chain line A in Fig. 5 with the horizontal wire 3a of the convex portion 3b as a fulcrum. However, since the vertical wire bars 1b 'and 1b' are located at the side edges, the eggs that have laid are not rolled through in this portion, so that the eggs do not stall midway.

Further, the vertical wire bars 1b ', 1b' on both sides are provided.
The vertical wire 1b in the middle part other than the above is not supported by the slant ceiling net 3 in the lower part thereof, so that the vertical wire 1b shown in FIG.
Bend like chain line B in FIG. Therefore, even if the flexural shape is plastically deformed over time, the eggs laid in the vertical wire 1b portion roll to the egg receiving portion 1d without stagnating in the middle of the bottom net 1a. Even if the egg stops at the front fulcrum c of the vertical wire 1b, the egg will not be stepped on by the chicken due to the existence of the egg guard 8.

[0017]

As described above, according to the present invention, since the laid eggs do not stay in the middle of the bottom net of the cage, it is possible to prevent soiled eggs and ruptured eggs. Also, the bottom net of the upper cage can be sufficiently reinforced.
