Abstract

PROBLEM TO BE SOLVED: To provide a circulation conveyer for conveying the feed for domestic animals to individual animal feed feeders set in every chamber of a livestock barn or for transferring the feed to other conveying lines in which a fullness detection switch is omitted in order to avoid the complication of movement of the fullness detection switch that is required to move according to the variation of feeding mode in the barn as well as to inhibit the overload of the feed on the circulation conveyer caused by the confluence of excessive feed and a fresh feed flow from a feed storage tank. SOLUTION: The circulation conveyer 6 and the animal feed feeder are separately driven. The animal feed is fed to the circulation conveyer via a feed outlet 5 opened at a part of the conveyer until the feed outlet 5 for feeding the feed to prescribed places is filled with the animal feed. When the conveying is completed, the returning of feed as excessive feed is started and the returning feed is conveyed back to the animal feed feeder again. This returning feeding is detected by a feed-returning detector and the animal feed feeder is stopped itself from driving.

2. Description of the Related Art Livestock such as cattle and pigs are housed in a stall divided into a plurality of subdivisions at the time of breeding, and feed is supplied to a feeder attached to the stall. Livestock feed on the feed stored in this feeder.

[0003] Recent large-sized livestock stalls are internally divided into a large number of stalls, and each stall is provided with one or more feeders according to the number of livestock to be accommodated. All feeders must be able to effectively carry the required amount of feed.

[0004] To this end, as shown in FIG. 1, a suitable transport means provided in a circulating transport pipe 6 'passing through a feed outlet 3' connected below the feed storage tank 1 '. (Not shown) is circulated by the drive unit 2 ', and the feed is moved and conveyed along with the movement of the conveying means (not shown), and is provided at an appropriate position in the circulation path of the circulation type conveyance pipe 6'. Feed outlets 4 'provided with a fill detection switch 5' at the bottom of the circulation route while sequentially filling the plurality of feed outlets 4 'and feeders and the like (not shown) below the feed outlets 4'. Is full, the operation of the drive unit 2 'is stopped by the detection of the fullness detection switch 5' and the transfer operation is completed. When the operation of the drive unit 2 'is restarted, the amount of feed in the feeder (not shown) below the filling detection switch 5' is reduced by feeding of livestock, and the filling detection switch 5 'indicates an unfilled state. Alternatively, it is realized by a forced start operation.

[0005] When the breeding system of the livestock barn is the "all-in-all-out" system in which all the livestock accommodated in the entire livestock barn are simultaneously introduced / removed, the filling detection switch described in the preceding section always operates as shown in FIG. If it is located at the bottom of the transport route, the automatic operation of feed transport is reliably achieved.

However, in response to the increase in the size of the livestock barn and changes in the breeding mode, it is impossible to always set the position of the fullness detection switch at the lowest position of the transport route. To keep the livestock always in the stall where the filling detection switch is installed, or
A plurality of fullness detection switches are distributed and arranged at appropriate positions in the transport path in the barn, and the fullness detection switch at the lowest transport position in each breeding mode is selectively operated, and further,
A control circuit for a charge detection switch is laid throughout the animal barn so that it can correspond to any position of the charge detection switch in the entire area of the barn, and the charge detection switch is changed to an arbitrary position as a portable type to respond The method has been taken.

[0007]

SUMMARY OF THE INVENTION According to the present invention, in consideration of the above-mentioned situation, a filling detection switch attached to a circulation path type conveyance device is omitted, and a filling detection switch required every time the breeding mode changes is changed. It is intended to eliminate the inconvenience that the transportation route is filled with surplus feed due to the inactivity of the filling detection switch and the transportation means is damaged, while eliminating the complexity of the movement.

[0008]

In order to solve the above-mentioned problem, according to the present invention, as a feed supply device for feeding feed to a circulating transport device having transport means circulating endlessly, the transport capacity of the circulating transport device is adjusted. The feed supply device that does not exceed the above is driven by a drive system different from the circulation conveyance device, and feed is supplied to the feed supply port of the circulation conveyance device.

[0009] The feed discharge port attached to the circulating conveyance device,
It is installed at one or more arbitrary locations along the circulation path of the circulation transport device, and feeders are provided below each feed outlet, and each is disposed at a predetermined position in the stall. .

[0010] The feed supply port penetrates and opens a part of the path of the circulating conveyance device below the box connected to the feed supply device to supply the feed into the conveyance path, and at the same time to supply the feed into the conveyance path. Therefore, it is possible to receive the feed from the feed supply device of the separate drive system, and to receive the surplus transported feed after filling all the feeders installed along the transport route described in the preceding paragraph with the feed. I do.

The surplus feed is detected by a feed recirculation detection device provided in the feed supply unit, and the feed recirculation detection device stops the operation of the feed driving device of another drive system, and further moves to the transport path of the circulating transport device. By stopping the inflow of surplus feed and preventing excessive inflow into the transport route, overload on each component of the circulating transport device is prevented.

[0012]

In the circulating transport device according to the present invention having the above-described structure, surplus feed in the circulatory transport route is reliably detected by the feed recirculation detecting device, and excess feed is allowed to flow into the circulatory transport route. And always maintain the appropriate transport level,
Suppress excessive load generation in the components of the transfer device,
In addition, the feed can be always supplied to the feeder at any position in the barn.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 2, a circulating conveyance device according to the present invention includes a feed supply port 4 for receiving feed supplied by a feed supply device 3 connected below feed storage tank 1, and a feed supply port. 4 has an opening through which feed can be supplied, and constitutes a closed system path in which an endless conveying means (not shown) is provided.

The circulating transfer device 6 having the closed system path described above.
Has a suitable transport means (not shown) for transporting the feed therein, and the transport means is circulated by a transport drive unit 2 having one or a plurality of suitable drive systems. The feed supplied from the feed supply port 4 is moved and conveyed along with this movement.

Here, in order to realize the present invention, it is assumed that the relationship of "feeding ability of the circulating transporting apparatus≥transporting ability of the feed feeding apparatus" is maintained with respect to the feeding ability of the feed. This is because if the reverse relationship is set, the feed in the circulating and conveying device 6 becomes overfilled in the circulating and conveying device, and an excessive load is applied to the conveying means to make it impossible to operate.

The above-mentioned circulating transport device 6 is provided with one or a plurality of feed outlets 5, and the moving feed is fed through the feed outlet 5 to a feeder below. The feed is supplied to another feed transport path (not shown) or another feed transport path (not shown). As can be easily understood from FIG. 2, the plurality of feed outlets 5 are located on the upper side of the circulation path. The feed outlet 5 on the lower side is filled while filling the feed outlet 5 sequentially.

When all the feed outlets 5 are filled with feed, the surplus feed reaches the return feed outlet 71 provided below the final feed outlet 51 located at the lowest position in the circulation path, and the feed returns. Via the discharge port 71, it comes into contact with the feed reflux detection device 7 fixed inside the box 41 constituting the feed supply port 4.

The surplus feed that has come into contact with the feed recirculation detecting device 7 falls as it is and is again sent to the circulating transport device 6 via the feed supply port 4.
When it detects that the surplus feed comes into contact, the operation of the feed supply device 3 is stopped, and the supply of further new feed to the circulation / conveyance device 6 is stopped.

In the embodiment shown in FIGS. 2 and 4, all surplus feed does not flow out from the return feed outlet 71, but remains in the circulating transport device 6 so as not to return to the feed supply port 4 again. The surplus feed is allowed to flow down from the reflux feed withdrawal hole 8 and returned to the feed supply port 4 again. This configuration is equivalent to the non-discharge range 6
1, the partition plate 81 has an effect of maintaining the function of the feed recirculation detecting device 7.

When the operation of the feed feeding device 3 is stopped, the supply of new feed is naturally stopped in the circulating transport device 6, so that the quantitative level of the transported feed in the circulating transport device 6 is determined during normal transport. Therefore, it is possible to prevent the occurrence of a failure in each part constituting the circulating transport device 6 without causing an overload in the transport route.

If the operation of the circulating transport device 6 is further maintained while the operation of the feed supply device 3 is stopped, each feed outlet 5
Even if a gap occurs in the feed outlet 5 due to the livestock feeding the feed from a feeder below the feeder or the like, the feed existing in the path of the circulation conveying device 6 between the feed outlets 5 is immediately replaced by the gap. However, if the volume of the generated voids is larger than the volume of the above-mentioned remaining feed, there is no feed reaching the return feed outlet 71, and there is no feed that comes into contact with the feed reflux detection device 7, and at this time, , The operation of the feed supply device 3 is restarted,
Feed supply to the circulating transport device 6 starts again, and feed supply is continued while appropriately maintaining the quantitative level of the transported feed in the transport path.
