[Problems to be solved by the invention]
In broiler breeding, different feeds according to the growth stage are given from chicks to adult chickens.
Feeding at the stage of chicks with weak resistance is important for growing healthy chickens. At this time, the growth is fast, so it is necessary to give a sufficient amount of nutritious feed. This highly nutritious and oily feed is sticky and easily causes a bridging phenomenon in the falling hood, etc., so that the feed flow gap between the falling hood and the feeding tray is widened to allow the feed to feed. It is preferable to ensure a good supply on top. On the other hand, when it becomes close to an adult chicken, it becomes a hard and smooth feed, and when the feed flow gap is large, feed is excessively produced. Therefore, it is preferable to narrow the feed flow gap.
[0004]
However, in the conventional feeding device, as described above, it is necessary to manually adjust the feed flow gap by operating the locking member, and adjusting a large number of feeding devices requires a great deal of labor. .
Therefore, in practice, the current feed flow gap is adjusted to an intermediate feed flow gap in advance, and the same feed flow gap is set from the chick to the adult chicken stage. It was far from ideal feeding, for example, the amount of feed in Japan was reduced.
[0005]
Therefore, the present invention has been made to solve the above-described problems, and the object of the present invention is to provide a poultry feeding device that can automatically adjust the feed flow gap according to the breeding stage and can perform ideal feeding. To provide.

[0013]
The outer cylinder 20 is locked to the inner cylinder 19 so that the position in the vertical direction can be adjusted in a plurality of stages.
FIG. 5 shows details of the outer cylinder 20.
The lower part of the outer cylinder 20 spreads outward in a trumpet shape, and forms a feed flow gap 30 that allows the feed to flow down on the feeding dish.
Two protrusions 31 protruding inward are provided on the upper edge of the outer cylinder 20 at positions facing each other. Reference numeral 32 denotes a knob portion.
[0014]
The outer cylinder 20 moves the protrusion 31 upward along the inner cylinder 19 so as to enter the vertical groove 23a of the inner cylinder 19 from below, and when the protrusion 31 reaches the upper end of the vertical groove 23a, the outer cylinder 20 By rotating the outer cylinder 20, the protrusion 31 gets over the protrusion 24, enters the vertical groove 23e, and further rotates the outer cylinder 20 in the lateral direction while moving up and down in the vertical groove 23e. It can be made to enter any of the lateral grooves 23b, 23c, 23d.
That is, the height of the outer cylinder 20 can be adjusted in three stages with respect to the inner cylinder 19.
The adjustment hood 18 is composed of the inner cylinder 19 and the outer cylinder 20, but may be formed of a single cylindrical body.
[0015]
A rod-like body 34 extending in the vertical direction is fixed to the center portion of the outer cylinder 20 via a plurality of connecting ribs 33. The ribs 33 are plate-shaped so as not to hinder the fall of the feed. In the embodiment, three ribs 33 are used at intervals of 120 °. Needless to say, the rib 33 is fixed at a position that does not hinder the movement of the outer cylinder 20 relative to the inner cylinder 19.
The rod-shaped body 34 in the embodiment has a pipe shape with its upper end closed, and the upper portion extends into the inner cylinder 19 and has a function of distributing the feed falling in the adjustment hood 18 in the circumferential direction together with the ribs 33.
[0016]
The lower portion of the rod-like body 34 extends longer than the lower end of the outer cylinder 20 and protrudes downward through a through hole provided in the center of the bottom member of the feeding tray described later.
Further, the portion of the rod-like body 34 projecting downward from the bottom member is bifurcated as shown in FIG. 6, and the branch piece 35 approaches the branch piece 35 against the elastic force by sandwiching the branch piece 35 with a finger. It is supposed to be made.
A projecting portion 36 that projects outward from the outer periphery is formed at the lower portion of the branch piece 35.
[0017]
Next, the feeding tray 40 will be described.
As shown in FIG. 1, the feeding tray 40 is configured such that the ring-shaped attachment portion 42 of the net frame portion 41 is inserted between the locking protrusion 16 and the locking ring 15 of the falling hood 14, thereby 14 is attached.
As shown in FIG. 7, the net frame portion 41 has a plurality of arms 43 that extend radially from the attachment portion 41 and extend downward. From the gap between the arms 43, if it is a chick, the chick can enter the feeding tray 40 and pour the feed, and if it is an adult chicken, it can plow the neck and pour the feed.
[0018]
A ring portion 45 that forms a part of the feeding tray 40 is fixed to the net frame portion 41 at the lower ends of the plurality of arms 43.
The ring portion 45 has a cylindrical shape having a required width (for example, about 3 cm) in the height direction.
Further, the lower end portion of the ring portion 45 is formed in a throttle portion (locking portion) 45a having a diameter reduced toward the lower side.
The plate body 46 (FIG. 1) is attached to the ring portion 45.
[0019]
The dish body 46 has a shallow dish shape with a body part 47 (FIG. 8) and a bottom member 48 (FIG. 9).
An engaging portion 47 a that enters the ring portion 45 and engages with the upper surface of the locking portion 45 a of the ring portion 45 protrudes outward from the upper edge of the main body portion 47.
Therefore, the plate body 46 can move up and down with respect to the ring portion 45 within the range of the width (height) of the ring portion 45, and moves downward when the engagement portion 47a is engaged with the engagement portion 45a. Is regulated.
In this manner, the depth of the feeding tray 40 can be adjusted by moving the tray body 46 up and down relative to the ring portion 45.
[0020]
A central portion of the main body 47 is largely opened in a circular shape, and a lower wall 49 extending downward in a substantially cylindrical shape is formed in the opening. The lower wall 49 is provided with a plurality of notches 50 that extend in the circumferential direction and then open at the lower edge at appropriate intervals in the circumferential direction.
As shown in FIG. 9, the bottom member 48 is formed in a substantially conical shape, and a through hole 52 through which the lower portion of the rod-shaped body 34 passes is formed at the top. The edge of the through hole 52 is a protruding peripheral edge 52a that protrudes slightly inward. A bottom wall of the bottom member 48 is formed with a substantially cylindrical fitting wall 53 that fits into the lower wall 49 of the main body 47 from the inside. A plurality of protrusions 54 are provided on the outer surface of the fitting wall 53 at appropriate intervals in the circumferential direction.
[0021]
When the bottom member 48 is applied to the main body 47 so that the protrusion 54 enters the notch 50 and the bottom member 48 is rotated in the lateral direction, the protrusion 54 enters the circumferential portion of the notch 50, thereby The bottom member 48 can be attached to the main body 47. To remove it, the bottom member 48 may be rotated in the reverse direction.
The conical portion of the bottom member 48 protrudes above the main body 47, and the feed flow gap 30 as described above is the gap between the tapered surface of the upper surface and the lower surface of the tapered surface below the outer cylinder 20 of the adjustment hood 18. It becomes.
Reference numeral 55 denotes a reinforcing rib.
[0022]
Next, the operation will be described.
Many feeding apparatuses 10 are attached to the transport pipe 11 in a suspended state. The transport pipe 11 is used by being able to move up and down by a suspension device (not shown).
In the growth stage of the chicks, the transport pipe 11 is lowered, and the bottom of the feeding tray 40 is in contact with the floor as shown in FIG.
Thereby, the feeding tray 40 becomes shallow, the chick can easily enter the feeding tray 40, and can feed the food.
Further, when the bottom of the feeding tray 40 comes into contact with the floor surface, the rod-shaped body 34 moves upward, the adjustment hood 18 rises, thereby widening the feed flow gap, and the feed is sufficiently placed on the feeding tray 40. Supplied. Even if the feed is highly sticky and contains oil, the feed flow gap 30 is large, so that the feed is suitably supplied to the feeding tray 40. Therefore, the bridging phenomenon of feed is also avoided as much as possible.
[0023]
As the chicks grow, the transport pipe 11 is pulled up. As a result, the dish main body 46 side remains in contact with the floor surface, but the ring portion 45 is pulled up, so that the height of the feeding dish 40 is sequentially increased to match the growth of the chicks. It will be appreciated that the size of the feed flow gap 30 does not change.
In this way, the feed can be sufficiently fed at the chick stage.
As shown in FIG. 11, after the engaging portion 47a of the plate main body 46 abuts on the locking portion 45a of the ring portion 45, when the transport pipe 11 is further pulled up, the plate main body 46 side is also raised accordingly. . The rod-like body 34 remains in contact with the floor surface. Thereby, it is understood that the feed flow gap 30 is gradually narrowed.
[0024]
At this stage, the chicken has grown considerably, and the feed is also different from that for chicks, and is a free-flowing solid feed. Therefore, even if the feed flow gap 30 becomes narrow, the feed is sufficiently on the feeding tray 40. Feed is supplied.
Although the chicken is tall, it can easily pour its neck into the raised food tray 40 and pour the food.
[0025]
When the locking protrusion 20 of the inner cylinder 19 is locked to the locking protrusion 17 of the drop hood 14, the adjustment hood 18 is also lifted thereafter, so that the size of the feed flow gap 30 remains unchanged. This stage is almost time for shipping chickens.
As described above, since the feed flow gap 30 can be adjusted continuously or stepwise according to the growth stage of chicks and chickens, ideal feeding can be performed.
In particular, although feeding at the chick stage is important, this feeding device 10 can provide sufficient feed.
[0026]
When the breeding is finished, the feeding device 10 needs to be washed.
In the feeding device 10 of the present embodiment, cleaning can be easily performed.
That is, as shown in FIG. 13, the bottom member 48 is removed from the main body 47 by rotating the bottom member 48 of the feeding tray 40 about the axis.
The bottom member 48 moves downward and stops at a position where the protruding peripheral edge 52a abuts on the protruding portion 36 provided below the rod-like body 34.
In this way, the bottom of the dish body 46 can be greatly opened, so that the remaining feed can be easily discharged and can be easily washed with washing water. Washing water does not remain in the dish.
[0027]
Further, since the bottom member 48 is suspended from the rod-like body 34, there is no need to worry about the place of placement, and a large number of feeding devices 10 can be cleaned with good workability. Since it is not necessary to place the bottom member 48 on the floor surface or the like, it is also hygienic. In addition, it is easy to assemble the main body 47 again after cleaning, which can be performed efficiently.
Further, the bottom member 48 can be completely separated by shrinking the branch piece 35. Thereby, the outer cylinder 20 is moved, and the height of the outer cylinder 20 relative to the inner cylinder 19, that is, the initial size of the feed flow gap 30 can be easily set, and other repairs can be easily performed.
[0028]
【The invention's effect】
According to claim 1, according to the growth stage of chicks and chickens, the size of the feed flow gap can be automatically adjusted just by pulling up the feeding device from the abutting part such as the floor surface. Feed can be easily and sufficiently supplied onto the feeding tray, and ideal feeding becomes possible.
According to the second aspect, the initial feed flow gap can be adjusted.
According to claim 3, since the depth of the feeding dish can be easily adjusted according to the growth stage of the chicks and chickens, suitable feeding can be performed.
