When the bottom member 48 is applied to the main body 47 so that the projection 54 enters the cutout 50 and the bottom member 48 is rotated in the lateral direction, the projection 54 enters the circumferential portion of the cutout 50, As a result, the bottom member 48 can be attached to the main body 47. To remove it, the bottom member 48 may be rotated in the opposite direction. The conical portion of the bottom member 48 projects above the main body portion 47, and the tapered surface of the upper surface thereof and the adjustment hood 18
The gap between the lower surface of the outer cylinder 20 and the lower surface of the tapered surface becomes the feed-down gap 30 as described above. Reference numeral 55 is a reinforcing rib.

Next, the operation will be described. The feeding device 10 is
A large number are attached to the transport pipe 11 in a suspended state.
The carrier pipe 11 is used by being vertically movable by a hanging device (not shown). In the growing stage of the chicks, the transport pipe 11 is lowered, the bottom of the feeding dish 40 is in contact with the floor, and the dish body 46 is moved upward with respect to the ring portion 45, as shown in FIG. As a result, the feeding plate 40
Since the chicks become shallower, the chicks can easily enter the feeding dish 40 and can peck the bait. Further, when the bottom of the feeding dish 40 comes into contact with the floor surface, the rod-shaped body 34 moves upward and the adjustment hood 18 rises, whereby the feed flow gap is widened and the feed is sufficiently placed on the feeding dish 40. Supplied.
Even if the feed contains oil and is highly sticky, the feed flow gap 30 is large, so that the feed is suitably supplied to the feeding tray 40. Therefore, the feed bridging phenomenon is also avoided as much as possible.

As the chicks grow, the carrier pipe 11 is pulled up. As a result, the plate body 46 side remains in contact with the floor surface, but since the ring portion 45 is pulled up, the height of the feeding plate 40 gradually increases, and the feeding plate 40 is adjusted to the growth of the chicks. It will be appreciated that the size of the feed gap 30 does not change. In this way, the chicks can be fully fed. As shown in FIG. 11, when the transport pipe 11 is further pulled up after the engaging portion 47a of the dish body 46 abuts on the locking portion 45a of the ring portion 45, the dish body 46 side is also pulled up accordingly. . The rod-shaped body 34 remains in contact with the floor surface. As a result, the feed gap 3
It is understood that 0 is gradually narrowed.

At this stage, the chicken has grown considerably, the feed is also different from that for chicks, and since it is a free-flowing solid feed, even if the feed flow gap 30 becomes narrow, the feeding plate is sufficiently fed. 40 is fed with feed. Although the chicken is tall, it is possible to easily plunge its neck into the raised feeding tray 40 to grab the feed.

The locking projection 20 of the inner cylinder 19 is used for the drop hood 1.
When the locking ridge 17 of No. 4 is locked, the adjustment hood 18
Also, the size of the feed gap 30 does not change. At this stage, chickens are almost shipped. As described above, since the feed flow gap 30 can be adjusted continuously or stepwise according to the growth stage of the chicks and chickens, ideal feeding can be performed. Although it is particularly important to raise the chicks at the stage, the feeding device 10 can provide sufficient feed.

When the feeding is completed, it is necessary to wash the feeding device 10. The feeding device 10 of the present embodiment can also be easily washed. That is, as shown in FIG. 13, by rotating the bottom member 48 of the feeding tray 40 about the axis, the bottom member 48 is removed from the main body 47. Bottom member 4
8 moves downward and stops at the position where the projecting peripheral edge 52a abuts the projecting portion 36 provided on the lower portion of the rod-shaped body 34. In this way, the bottom of the dish main body 46 can be largely opened, so that the remaining feed can be easily discharged, and the dish can be easily washed with washing water. The wash water will not remain in the dish.

Further, since the bottom member 48 is suspended from the rod-shaped body 34, there is no need to worry about the place where the bottom member 48 is placed, and a very large number of feeding devices 10 can be washed with good workability. Since it is not necessary to place the bottom member 48 on the floor or the like, it is suitable for hygiene. Further, after the cleaning, the work of reassembling the main body portion 47 is easy and can be performed efficiently. Further, the bottom member 48 can be completely separated by squeezing the branch pieces 35. As a result, the outer cylinder 20 can be moved to easily set the height of the outer cylinder 20 with respect to the inner cylinder 19, that is, the initial size of the feed flow gap 30, and other repairs.

[0028]

According to the first aspect of the present invention, the size of the feed flow gap can be automatically adjusted by simply pulling up the feeding device from the abutting portion such as the floor surface according to the growth stage of the chicks and chickens. The feed according to the growth stage can be easily and sufficiently supplied on the feeding plate, and ideal feeding becomes possible. According to claim 2, the initial feed-down gap can be adjusted. Further, according to the third aspect, the depth of the feeding plate can be easily adjusted according to the growth stage of the chicks and chickens, so that suitable feeding can be performed.
