Description

[Detailed description of the invention] This invention relates to a feeding device that simultaneously feeds a large number of chickens.

In general, this type of feeding device mainly consists of a feeding device that feeds feed from a tank into a feeding pipe, a feeder connected to the feeding pipe, a link chain that transfers the feed in the feeding pipe to the feeding device, and a drive link chain. The feeder is provided with a drive device that allows the chickens to peck at the feed that is sequentially fed into the feeder by means of a link chain.

However, most of the above-mentioned feeding devices are in the form of a hopper that stores the feed fed from a feed tank, and therefore the feed is fed by dropping the feed in the hopper into the feeding pipe simply by the action of gravity. There is.

For this reason, with such a hopper-type feeding device, there is a lot of variation in the feed amount, and if a large amount of feed is fed at once, there is a risk that the feed pipe will be blocked and the chain link will become difficult to drive. In addition, due to the occurrence of so-called pritzing, the feed in the hopper becomes bridging and stagnates near the sunrise, resulting in the disadvantage that old feed remains in the hopper.

Moreover, the feed is sequentially supplied from the feeder closest to the feeder by a link chain driven at a low speed of 10 to 20 m per minute, and during this time the chickens are allowed to forage the feed in the feeder. For example, the length is 100m.
If the link chain is driven at a speed of 10 m/min in a feeding device, it will take 10 minutes to complete one round of the device, and as a result, the feeder closer to the feeder and the feeder farther away will be separated. There will be a time difference in feed supply.

Therefore, the chickens will start feeding from the feeder that was supplied with feed first, and since chickens have a tendency to eat coarse feed first, the feeder that is fed later will start to feed. Only fine-grained feed was fed to the chickens, making it impossible to feed even and homogeneous feed to all chickens at the same time.

The purpose of this invention is to install a sprocket driven by a link chain in the feed supply device to supply a fixed amount of feed while stirring it into the feed pipe, and to control the feed amount of the hopper of the feed device that accommodates the feed. In addition, by driving the link chain at high speed, the chickens cannot feed while the link chain is being driven, thereby making it possible to constantly supply fresh, uniform, and homogeneous feed in a constant quantity at the same time. It is to provide.

Next, this invention will be explained with reference to illustrated embodiments.

In FIG. 1, a feeding device 1 feeds a fixed amount of feed from a tank (not shown) into a feeding pipe 2 while stirring the feed, and the feed fed into the feeding pipe 2 is fed by a chain link (
2 and 3).

This chain link is driven at a speed of 40 to 5 Qm per minute by a drive device 3 comprising a motor, a reduction gear, a sprocket, etc.

A feeder, for example a feeding trough 4, is arranged 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 arranged in a rectangular shape, and the supply pipes 2 connecting each device are connected to each other at each corner by a connecting device 5 provided with a sprocket.

As shown in FIG. 2, the link chain 6 is made by welding two disks 7 that engage with the sprocket of the drive device 3 with a pin 7a, and connecting them to a rod-shaped connecting piece 9 through a washer 8.
The connecting pieces 9 are connected to each other so that they can move indirectly, and the feed is transferred by the disc 7.

As shown in FIG. 3, the feeding device 1 has a housing 1a, the bottom 1b of which is obliquely shaped, and a sprocket 10 driven by a disc 7 of a chain link 6 is rotatably mounted thereon.

A hopper 11 for accommodating feed is provided on the inner side wall of the housing 1a of the feeding device 1, and this hopper 11 is connected to the bottom 1.
The sprocket 10 has an open bottom obliquely shaped along the direction b, and the bottom is provided so as to cover a portion of the sprocket 10 and relatively close to the portion.

The sprocket 10 is arranged so that its teeth pass under the hopper 11 close to said side wall.

Therefore, the feed in the hopper 11 can be agitated by the sprocket 10 and fed in fixed amounts from the outlet end of the hopper 11 toward the chain link 6 by its teeth.

The outlet end through which the feed passes has an opening 11a, which is formed into a slot 1lb formed on the hopper 11.
It is controlled by an opening/closing plate 13 fitted with a thumb screw 12 guided therein, and the operator can adjust this opening/closing plate 13 to control the amount of feed supplied as required.

As shown in FIG. 4, the feeding trough 4 also has a bottom 14 through which the link chain 6 passes and which acts as a feeding section which also serves as a feeding section;
Opposite walls 15 and 16 are integrally formed and are inclined toward the bottom and have seven lunges 15a and 16a, and the lower wall 15 is installed on the cage side so that the chickens can cross this wall and reach the bottom 14.
The upper wall 16 is shaped to prevent forage from scattering.

With the above structure, feeding starts when the chain link 6 is driven by the drive device 3, the sprocket 10 in the feeding device 1 rotates, and feed starts to be fed into the feeding pipe 2, and the chain link 6 Feeding is completed when the chicken passes through each feeding trough 4, goes around the inside of the device, and is stopped. Because the driving speed of the chain link 6 is fast, the chicken cannot forage while the chain link 6 is being driven. When it stops, the feed in the trough 4 can be foraged all at once.

In this case, setting of the feeding time and control of the drive device can be performed electrically by a control unit having an electric circuit.

Note that a bread-type feeder may be used instead of the feeding trough 4.

According to this invention, the feed supply device is equipped with a sprocket driven by a link chain to supply a constant amount of feed while stirring it into the feed pipe, and the chain link is driven at a relatively high speed. It is possible to avoid clogging of the supply pipe and the remaining of old feed in the hopper, which occur in conventional feeding devices, and it is possible to constantly supply fresh, uniform, and homogeneous feed at a fixed amount at the same time.

Furthermore, it is possible to adjust the amount of feed supplied as necessary using the hopper of the feeding device that accommodates the feed.
