Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shutter device for a poultry feeding device, and more particularly, the present invention relates to a shutter device for a poultry feeding device. This invention relates to a shutter device for a discharge port in a poultry feeding apparatus which opens the discharge port and allows the chicken to fall onto a saucer suspended below a feed pipe.

Conventionally, a pipe is arranged horizontally in the chicken house, feed for poultry farming is fed by a screw conveyor built into this pipe, and a large number of feed outlets are opened at appropriate locations on the lower side of this feeding pipe. There is a device in which a receiving tray is provided below each discharge port via a trumpet-shaped drop tube, and feed is fed to each receiving tray at the same time.

However, when using this device, it is possible to use chicken houses that do not require feeding,
If it is necessary to feed a different type of feed only to a specific chicken house, or to leave a part of the feed system in one chicken house idle, install a feed pipe droplet for each feed system. Measures are taken to open and close the

One method is to cut out a piece of steel or synthetic resin pipe in the longitudinal direction, which has the same inner diameter as the outer diameter of the feed pipe, and make it elastic so that the shutter can be attached to and removed from the feed pipe. This is the one that opens and closes the drop port.

To install this shutter, either attach the shutter to either the left or right side of the drop tube attachment part of the feed pipe and slide it into the gap between the feed pipe and the drop tube, or insert the shutter into the drop tube attachment part of the feed pipe. This is done by attaching a shutter to the upper side and sliding it downwards, but these operations are cumbersome and cannot be operated all at once.

In order to be able to operate the shutters all at once, a gutter-shaped receiving part with a hole of the same size as the discharge port is interposed between the feed pipe and the drop tube, and half-moon-shaped side plates are placed on both sides of this receiving part. A shutter with a hole about the same size as the discharge port is provided between the receiving part and the feeding pipe, supported by the half-moon-shaped side plate and the upper edge of the receiving part inside in the longitudinal direction. Some feeders are designed to feed when the discharge port and the holes in each member align and communicate with each other by sliding.

However, because the curvature of the gutter-shaped receiving part is different from the curvature of the feed pipe, two types of drop tubes have to be produced, one with a shutter and one without, with different cutouts on the top edge of the drop tube.

An object of the present invention is to facilitate the opening and closing operation of the shutter,
It is also possible to link the shutters of each feeding device at the same time, and the notch on the top edge of the drop tube almost matches the outside diameter of the feeding pipe, so it can be installed as is on conventional feeding devices without shutters. An object of the present invention is to provide a shutter device for a poultry feeding device that does not require any change in the design of the conventional feeding device.

Embodiments of the present invention will be described in detail below with reference to the drawings.

10 is a feeding pipe, which is installed horizontally inside the chicken house.
Poultry feed is fed by a screw conveyor built into the pipe.

Reference numeral 12 denotes a discharge port, which is opened at an appropriate location on the lower side of the feed pipe.

Reference numeral 14 denotes a drop tube having a trumpet shape, with its wide mouth facing downward and its small mouth covering the discharge port 12 of the feed pipe 10.

A saucer (not shown) with a raised central portion is provided at the lower end of the drop barrel 14, and the distance between the raised portion of the saucer and the drop tube 14 can be adjusted to enable fixed-quantity feeding.

Reference numeral 16 denotes a frame plate, which has the same shape as the feed pipe 10 and has a gutter shape, and is inserted between the feed pipe 10 and the drop tube 14.
0, and is supported by the opening edge of the upper end of the drop tube 14.

A portion of the frame plate 16 corresponding to the portion where the falling tube 14 is fixed to the feed pipe 10 is cut out to allow escape.

A slit 20 is provided along the longitudinal direction approximately at the center of the frame plate 1G, and the discharge port of the feed pipe 10 faces from one end of the slit 20.

Reference numeral 22 denotes upright portions of the frame plate, which stand up at both edges of the frame plate 16 on the slit side, respectively, toward the bottom, and are slightly inclined inward.

A space is created within the slit 20 by the thickness of the frame plate 22.

A shutter 24 slides in the slit 20 and opens and closes so that a wide portion 26 at the tip of the shutter 24 covers the discharge port.

A knob 28 of the shutter 24 is located at the rear end of the shutter 24.
is standing downward.

Reference numeral 30 denotes the origin of the shutter, which stands up downward on both side edges of the shutter 24, is inclined inward at the same angle as the upright part 22 of the frame plate, and has a longitudinal length equal to the diameter of the discharge port 12. It has been made longer.

The upright portion 30 of the shutter is held by the upright portion 22 of the frame plate, and is guided by sliding the shutter 24 within the slit 20.

Note that the wide part 26 at the tip of the shutter 24 is a slit 20.
Both sides of the wide portion 26 located below the surface are in sliding contact with the lower surfaces of both edges of the frame plate 16 on the slit side.

This is because when the wide portion 26 slides the slit 20 surface in the direction of closing the discharge I:] 12, the tip of the wide portion 26 hits the edge of the discharge port 12, completely closing the discharge port 12. This is to prevent this from becoming impossible.

With the above structure, the discharge ports 1 and 2 are opened and closed by pinching the knob 28 and sliding the shutter 24 within the slit 20, and when opened, feed is fed to the saucer through the drop tube 14. Ru.

Thus, according to the device according to the present invention, the shutter 24
The discharge port 12 can be easily opened and closed by simply sliding the knob 2 of each shutter of a large number of devices.
8 can be linked together using wires or the like, allowing multiple devices to be operated at once.

In particular, by adopting a configuration that eliminates the possibility of the end of the shutter hitting the edge of the discharge port, reliable simultaneous operation is possible.

Further, since only the frame plate 16 is interposed between the feed pipe 10 and the drop tube 14, the cut at the upper end of the drop tube 14 may have a shape corresponding to the feed pipe 10, and there is only one type. It can be used for general purposes with or without a shutter device.

Therefore, when a shutter device is attached to a feeding device lζ which does not have a shutter device, it is possible to improve the feeding device lζ by simply adding the frame plate 16 and the shutter 24 without replacing the drop tube 14.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.
