Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a feeding device that supplies feed to each of a plurality of livestock stalls in a livestock barn, and is designed to correctly supply a different amount of feed to each livestock stall. This paper relates to the feeding amount setting mechanism of the feed supply hopper used for this purpose.

(b) Prior art and its problems Conventional mechanisms of this type in this field include: (a) A slideable drop pipe is attached to the feed drop opening of the conveyance line, and its lower end is guided into the feed supply hopper. , a method for setting the feed amount by adjusting the height of the opening at the bottom end of the drop pipe; (b) A cylindrical structure with a shutter at the bottom and a movable partition plate inside, corresponding to the feed drop opening of the transport line. Two typical methods have been adopted: fixing the feed supply hopper and moving the movable partition plate to adjust the internal volume of the feed supply hopper to set the feed amount.

However, in the case of (a), since the adjustment mechanism is open, foreign matter may get into the feed supply hopper, and settings cannot be made accurately.In addition, the drop pipe makes the device long. There are drawbacks to doing so. In the case of (b), the movable partition plate and its operation mechanism are all built into the feed supply hopper, and the operation is transmitted using a link mechanism, etc., so the overall structure is complicated and the operation mechanism is difficult to maintain over a long period of time. There was a drawback that the mechanism could not be operated smoothly due to the adhesion of feed.

(c) Purpose of the invention In order to solve the above-mentioned problems, this invention first makes the feed supply hopper cylindrical in order to prevent foreign matter from entering the feed supply hopper and to eliminate the length of the device. Although it is fixed to the conveyor line as a closed structure and has a built-in internal volume adjustment mechanism, the adjustment operation is possible by eliminating indirect operation mechanisms such as link mechanisms and directly operating the adjustment mechanism from the outside. The present invention aims to provide a feeding amount setting mechanism that has a simplified structure and maintains a simple operation and a stable feeding amount setting function over a long period of time.

(d) Structure of the invention The feed supply hopper equipped with the feeding amount setting mechanism of this invention is a cylinder with a feed supply opening corresponding to the feed drop opening of the conveyance line at the upper end and a shutter that can be opened and closed near the lower end. It has a closed structure. Inside the feed supply hopper, there is built-in a hollow cylindrical adjustment tube which is fixed directly to the feed supply port at its upper end and hangs down, and which is made up of a plurality of stacked tubes and is extendable and retractable, and has an adjustment tube at its lower end. One end of the operation plate that operates the vertical expansion and contraction of the feed supply hopper is fixed, and the other end of the operation plate is made to protrude to the outside through a lip-shaped elastic body attached to a part of the outer wall of the feed supply hopper. The feed supply hopper is configured so that the internal volume of the feed supply hopper can be set by directly operating the built-in adjusting cylinder to extend and contract it up and down without using any component from the outside of the hopper.

(E) Description of Embodiments Hereinafter, the feed amount setting mechanism for livestock according to this invention will be explained in detail based on specific embodiments shown in the drawings.

Inside the conveyance line 1 connected to the feed tank (not shown), there are a suitable conveyance mechanism (not shown),
For example, a screw is built in, and a plurality of feed drop ports 2 are opened at appropriate intervals. The feed supply hopper 3 is fixed to the conveyance line 1 by stop bands 31a and 31b so that the feed supply port 4 corresponds to each feed drop port 2. Inside the feed supply hopper 3, an adjustment tube 5 is attached to the feed supply port 4 so that the adjustment tube 5 hangs down.
The upper end of the adjustment cylinder 5 is fixed, and the operation plate 6 is fixed to the lower end of the adjustment cylinder 5.

Since the adjustment cylinder 5 is composed of a plurality of stacked cylinders that engage with each other, even when it is extended downward by the operation plate 6, it always forms a cylinder shape as a whole.

Therefore, by operating the operating panel 6, the distance between the lower end opening of the adjustment cylinder 5 and the shutter 8 provided near the lower end of the feed supply hopper 3 can be arbitrarily set, and the distance between the lower end opening of the adjustment tube 5 and the shutter 8 provided near the lower end of the feed supply hopper 3 can be set arbitrarily. The acceptable volume of feed within 3 can be arbitrarily set depending on the interval setting.

One end of the operation plate 6 is fixed to the lower end of the adjustment cylinder 5, and the other end is connected to the outer wall of the feed supply hopper 3 in order to operate the adjustment cylinder 5 vertically and retractably from the outside of the feed supply hopper 3. A lip-shaped elastic body 7 having a length equal to the entire movement range of the operating plate 6 is provided in this penetrating portion.

The lip-shaped elastic body 7 consists of a pair of elastic bodies 7a and 7b.
are fixed to the outer wall 32 in a mountain-like manner toward the inside of the feed supply hopper 3 with both ends touching each other, and the operation plate 6 is inserted between the joints and penetrates the feed supply hopper 3. Therefore, no gap is created around the operating plate 6 due to mutual pressure, and the set position of the operating plate 6 is maintained. In order to prevent feed from leaking from the upper and lower ends of the lip-shaped elastic body 7, protruding plates 33a and 33b are provided.

When the supply of feed to the feed supply hopper 3 having such a feeding amount setting mechanism is completed, the shutter 8
The shutter 8 is opened and the feed stored inside the feed supply hopper 3 falls downward to be fed to the livestock.As shown in Fig. 5, the opening/closing mechanism of the shutter 8 is linked to the outside of the feed supply hopper 3. A mechanism is provided so that the shutter 8 can be opened and closed as desired by operating the crank arm 83.

When the feed supply hopper 3 having the structure described above is used, when the shutter 8 is closed and the lower end of the adjustment cylinder 5 is brought into contact with the shutter 8, the feed is only filled into the adjustment cylinder 5 to reach the set minimum amount and the feed is adjusted. As the lower end of the cylinder 5 moves away from the shutter 8, feed is filled inside the feed supply hopper 8 and into the adjustment cylinder 5. Therefore, by arbitrarily setting the position of the lower end of the adjustment cylinder 5, the amount of feed can be set as desired. You can set it.

(f) Effects of the invention As explained in detail above, the present invention realizes a feed supply hopper with a simple and closed structure, and can provide direct adjustment operation.
Effects such as making the feeding device more compact, preventing feed contamination, simplifying the feeding amount setting operation, improving setting accuracy, and facilitating maintenance due to the simple structure are produced.

By constructing the front surface of the outer wall of the feed supply hopper 3 with a transparent plate, the inside can be observed, and the inside can be easily cleaned by opening the shutter and pushing an air gun through the lip-shaped elastic body. This is possible.
