Description

[Detailed description of the invention] This invention mainly consists of a feeding device that supplies feed from a feed tank to a feeding pipe, a feeding trough connected to the feeding pipe, and a disk that circulates within the feeding pipe and transfers the feed to the feeding trough. The present invention relates to a feeding device that has a type link chain and a drive device that drives the link chain at a relatively high speed, and is capable of feeding feed to a large number of chickens at the same time.

In this type of feeding device, feeding starts when the link chain is driven by the drive device, the feed device starts feeding feed into the feed pipe, and the link chain passes through the feeding trough and enters the device. Feeding is completed when the feeder stops after completing one cycle. Since the driving speed of the link chain is fast, chickens cannot forage in earnest while the link is driving, but when the link stops, they can forage by pecking at the feed in the feeding trough all at once.

Normally, the feeding device is equipped with a sliding adjustment plate to control the size of the feed outlet opening in order to variously adjust the amount of feed depending on the breeding conditions of the chickens, for example.

However, since the adjustment plate is manually operated, it is difficult to handle it and it is difficult to accurately control the feeding amount. Therefore, in such a system, excess feed is often supplied, which increases the cost of feed and also increases the amount left over by the chickens, making it difficult to constantly supply fresh feed.

This invention is intended to eliminate these inconveniences, and will now be described with reference to illustrated embodiments.

The feeding device shown in FIG. 1 has a feeding device 2 that feeds a fixed amount of feed from a feed tank (not shown) into a feed pipe 1 while stirring the feed, and the feed fed into the feed pipe 1 is fed through a link chain. 3 (2nd, 4th
) into the feeding trough 4. This link chain 3 includes a motor, a take-up pulley,
It is driven at a relatively high speed of 40 to 50 m/min by a drive device 5 comprising a sprocket, tension spring, etc. A feeding trough 4 is placed in front of a chicken holding cage (not shown), and the chickens in the cage are allowed to peck at the feed transferred to this trough 4. The entire feeding device is constructed in a rectangular shape, and the supply pipes 1 connecting each device are connected to each other at each corner by a connecting device 6 provided with a sprocket. As shown in FIG. 2, the link chain 3 is formed by welding two discs 7 that engage with the sprockets of the drive device 5 with pins 7a to form a number of transfer parts, and these transfer parts are connected to washers 8. The connecting pieces 9 are connected to each other by rod-shaped connecting pieces 9 through the
The feeding section is designed to be able to move jointly, and the feed is transferred by the transfer section. The feeding trough 4 also has, as shown in FIG. 3, a bottom part 10 through which the link chain 3 passes and which acts as a feeding part, and an opposing wall inclined towards this bottom part 10 and provided with flanges 11a, 12a, respectively. 11 and 12 are integrally molded, and the lower wall 11 is installed on the side of the chicken housing cage so that the chickens can cross this wall and feed on the feed in the bottom part 10,
On the other hand, the higher wall 12 is formed to prevent feed from scattering.

As shown in FIG. 4, the feeding device 2 has a housing 13 connecting the feeding pipe 1, the bottom 13
A stirring member 14 is formed obliquely with respect to the supply pipe 1 and is rotatably provided with several teeth. This stirring member 14 has teeth that are connected to the housing 13.
It is mounted so as to be driven by said disc 7 of the link chain 3 which passes through the housing to prevent feed from forming bridging within the housing.
A hopper 15 for storing feed from the feed tank is provided on the side wall of the housing 13, and the delivery end of the hopper 15 is positioned above the inclined bottom 13a. Further, an auger 16, which is a screw-type transfer member, is rotatably supported at the bottom of the hopper 15, and this auger 16 is connected to a drive shaft 17a of a motor 17 attached to the opposite side wall of the housing 13, and rotates. The feed in the hopper is sequentially and quantitatively fed into the housing 13 from the delivery end. The motor 17 is connected to a control unit 18 having an electric circuit to control its operating timing and duration, and when the motor 17 is stopped, the auger 1
The supply of feed by No. 6 will also be stopped. Therefore, the amount of feed supplied is proportional to the operating time of the motor 17, and this control unit 18 is connected to the drive device 5.
Since the feeding amount and feeding timing are also controlled by the control unit 18, various settings and control can be performed.

With the above configuration, the control unit 18
When the link chain 3 is driven by the drive device 5 and the auger 16 in the hopper 15 is rotated by the motor 17 at the same time, the feed in the hopper is sequentially sent to the housing 13 by the auger 16, and then transferred to the link chain. A fixed amount of the liquid is supplied into the supply pipe 1 from the housing 13 while being stirred by the stirring member 14 which is rotating by 3. When the amount of feed supplied reaches the amount preset by the control unit 18, the motor 17 and auger 16 are stopped, and the feed supply is stopped. On the other hand, when the link chain 3 circulates within the feeding device and transfers the feed in the supply pipe 1 to the feeding trough 4, the drive device 5 stops driving the link chain 3 according to a command from the control unit, and the feeding device 3 stops driving the link chain 3. is completed.

Note that a limit switch 19 is provided above the housing 13 as necessary to detect the feed amount in the housing, and when the housing is full of feed, the motor 17 is stopped, and the feed is stopped. The supply may be stopped.

In this way, according to this invention, a hopper equipped with an auger that can supply a fixed amount of feed is provided to the feed supply device of the feeding device, and the auger is driven by a motor controlled by a control unit, so that the conventional adjustment plate is not required. Unlike control methods such as those described above, the feeding amount can be accurately controlled in various ways.
Therefore, it is possible to eliminate the supply of excess feed, to feed chickens in a way that is suitable for their rearing conditions, and to constantly supply fresh feed.
