DESCRIPTION:
BRIEF SUMMARY
FIELD OF TECHNOLOGY
The present invention relates to a device for supplying a constant feed for domestic fowls, pigs, etc., in more detail to a constant-feed supplying device which is capable of supplying a constant feed irrespective of the amount of charge in a feed-supplying hopper.
BACKGROUND TECHNOLOGY
In supplying a feed from a feed hopper to a feeder conduit, it is desirable that a prescribed feed rate should be maintained. A simple, conventional device for constant feed is based on feed control effected by adjusting the sectional area of a path through which the feed is sent from the feed hopper. However, such a device has a disadvantage in that the feed rate depends on the amount of the feed charge in the feed hopper. Another kind of device has been developed in which a cylinder with a rugged surface, capable of rotation, is placed horizontally within a vertical feed path from a hopper, a control plate is placed along the cylinder, and in which the feed is controlled by adjusting the interval between the cylinder and the control plate, thereby adjusting the width of the feed path, and is also controlled by forcing the feed to flow by means of the rotational force on the cylinder. This kind of device, though better than the other above-mentioned device, is still incapable of providing any satisfactory degree of constant feed; especially when plural control plates have been set within the vertical feed path for intended supply of feed to plural feeder conduits, a control of one of the control plates to narrow the corresponding path will cause more feed to flow in the direction toward the other control plates, and thus there is a mutual interaction among feed paths which prevents constant feed from being kept.
OUTLINE OF THE INVENTION
The object of the present invention is to offer a constant-feed supplying device capable of precise control, which is free of the disadvantages mentioned above. The present invention is characterized in that a desired number of flow paths are provided independently which lead a feed, introduced from a supply port connecting to the outlet opening of a feed hopper, to a discharge port practically horizontally and on an arc trace, each of the flow paths is provided with a control plate for adjusting the flow space, and that a driving mechanism is provided within the flow paths which transfers the introduced feed toward the discharge port.
The present invention may arrange a desired constant feed since a feed introduced from a feed hopper is forced to transfer horizontally and during this transfer the deposited feed layer is made uniform and adjusted in its thickness which determines the flow rate.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a side-view indicating the positional relation to the feeder conduit,
FIG. 2 shows a perspective drawing illustrating the attachment to the fixing frame,
FIG. 3 shows a view of the central vertical section indicating the inside of the casing,
FIG. 4 shows a view of the section specified by the A--A line in FIG. 3, and
FIG. 5 shows a plan for the rotary disk.
THE BEST STRUCTURE FOR THE EMBODIMENT OF THE INVENTION
As shown in FIG. 1, two-story cages 1 and 2 are provided with feeder conduits 3 and 4, and 5 and 6, respectively, along the upper and lower lines of the stories. Over the cages 1 and 2 is set parallel a pair of support rails 7 and 8. These support rails 7 and 8 support a fixing frame 13 capable of traveling via wheels 9, 10, 11, and 12. As shown in FIG. 2, the wheels 9 and 10 are fixed on a rotary shaft 14 supported on the fixing frame 13. These wheels 9 and 10 are allowed to serve as driving wheels when the set of a pair of pulleys 17 and 18 and a pulley belt 19 are arranged and are connected to the wheel shaft 14 with the output shaft 16 of a reversible motor 15 set on the fixing frame 13. On the other hand, the wheels 11 and 12 are supported capable of rotation as free wheels on the fixing frame 13 via wheel shafts 20 and 21, respectively. A feed-supplying hopper 23 (and 22) is provided in its lower section wit
