Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a pig feeder suitable for feeding piglets, and particularly to a feeder for pigs that can always feed a constant amount of feed regardless of the type or amount of feed. Regarding feeding devices.

[Conventional technology]

BACKGROUND OF THE INVENTION Feeders have traditionally been used in pig farms to feed pigs. These feeders are equipped with a hopper at the top, and the food in the hopper is sequentially supplied to the feeding tank at the bottom.

[The problem that the idea attempts to solve]

However, in the above-mentioned method, the feed may harden at the outlet of the hopper due to the pig's saliva or moisture when eating the feed. As a result, it was sometimes necessary to manually remove the hardened bait.

Therefore, the present invention is a pig feeder that has a simple structure that prevents the feed from clumping at the outlet of the hopper, allows a constant amount of feed to be fed at all times, and that allows the feed amount to be easily controlled according to the pig's intake. is intended to provide.

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the pig feeder of the present invention is a pig feeder in which a hopper having a feed drop opening at the bottom is disposed at the top of the feeding tank, and a cylindrical small diameter shaft part at the top. A boss portion having a stepped portion substantially in the middle of the body is provided in the feeding tank, and a shaft provided with the hopper is erected with the hopper screwed onto the boss portion such that the hopper can move up and down; A flange-shaped horizontal bait receiving portion is formed approximately in the middle of the outer peripheral wall of a hollow cylindrical body having a top plate through which the shaft passes and is open at the bottom, and an appropriate number of vertical grooves are formed in the inner peripheral wall of the hollow cylindrical body, and A feed holder having a discharge port communicating with the vertical groove formed in the lower part of the hollow cylindrical body is fitted onto the small diameter shaft portion of the boss portion so as to be vertically movable and rotatable, and is supported by the step portion. The upper part of the bait holder supported by the horizontal bait holder is inserted into the hopper from the drop opening, and a plurality of protrusions are formed on the lower surface of the outer edge of the horizontal bait holder.

[Effect]

Therefore, the bait falling from the hopper is deposited on the horizontal bait receiver and is also scattered in the bait tank.
When an appropriate amount of bait falls from the hopper, the bait is deposited in a column shape on the horizontal bait receiver, and the bait stops falling. In this state, the pigs can eat the food in the horizontal feed receiver or feed tank.

In the process of eating food, the pig's nose and mouth come into contact with the horizontal food receiver, causing the feed tray to move up and down, and the pig's nose and mouth coming into contact with the protrusions on the horizontal food receiver, causing the food receiver to move up and down. The table rotates, and due to this vertical movement and rotation, the bait accumulated in the horizontal bait receiver falls into the feeding tank, and the bait is replenished from the drop opening of the hopper into the horizontal bait receiver as appropriate.

Also, even if the bait hardens near the opening of the hoppa,
Since the top of the feed tray faces into the hopper from the drop opening, bait is pulled out from inside the hopper by vertical movement and rotation of the feed tray, and is constantly supplied from the hopper to the horizontal bait receiver and feeding tank. This prevents the bait from clumping at the outlet of the hopper, allowing a constant amount of bait to be fed at all times.

Moreover, since the shaft provided with the hopper is screwed onto the boss part so that the hopper can move up and down, the gap between the drop opening of the hopper and the horizontal bait receiving part can be adjusted.
The feed amount can be easily controlled according to the pig's intake.

Furthermore, an appropriate number of vertical grooves are formed on the inner circumferential wall of the bait holder, and a discharge port communicating with the vertical grooves is formed at the bottom, so that the bait can be removed from the gap between the shaft and the insertion hole in the top plate through which the shaft passes. Even if the bait gets into the cradle, it is discharged through the vertical groove from the outlet into the feeding tank, and the vertical movement and rotation of the bait cradle can be maintained smoothly for a long period of time.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

The pig feeder 1 is composed of a feeding tank 10, a feeding stand 20, and a hopper 30.

In the feeding tank 10, a side plate 12 is provided around the outer periphery of the bottom plate 11, and an appropriate amount of concrete C is filled in the area surrounded by the lower surface of the bottom plate 11 and the lower part of the side plate 12 to ensure stability. On the top,
A large number of protrusions 13 are formed, which stimulate the pig's nose and increase its appetite when it comes into contact with the nose when eating food.

A cylindrical boss portion 14 is formed by raising the center of the upper surface of the bottom plate 11 upward, and a male screw portion 15a of the shaft 15 is screwed into a female screw hole 14a screwed in the center of the boss portion 14. Together, a shaft 15 is erected, and the boss portion 14 and shaft 15 constitute a support column 16 for the hopper 30.

Furthermore, the boss portion 14 has a stepped portion 1 approximately in the middle of the body.
4b, and a cylindrical small-diameter shaft portion 14c is formed at the top of the stepped portion 14b.

The hopper 30 has a bait storage space inside, a bait drop opening 32 at the lowest end of a tapered part 31 formed below, a stay 33 fixed inside the tapered part 31, and a center of the stay 33. said shaft 15
The shaft 15 is supported by a nut 17 fixed to the male screw portion 15a of the shaft 15 inserted through the insertion hole 34.

The stay 33 has a semi-cylindrical upper surface, and is provided with protective plates 33a below both ends to prevent bait from entering around the nut 17.
5 has an upper part bent to form a handle 15b, and by turning the handle 15b, the screwing position between the male threaded part 15a of the shaft 15 and the female threaded hole 14a of the boss part 14 is changed, and the hopper 30 can be moved up and down. It makes it possible.

The bait pedestal 20 is attached to the small diameter shaft portion 14 of the boss portion 14.
The hollow cylindrical body 21 has a top plate 22 having an insertion hole 23 through which the shaft passes through the hollow cylindrical body 21, which has an inner diameter slightly larger than c and is open at the bottom.
A flange-shaped horizontal bait receiving portion 24 is formed approximately in the middle of the outer peripheral wall.

In addition, the feeding stand 20 has an appropriate number of vertical grooves 21a, for example eight, formed at equal intervals on the inner peripheral wall of the hollow cylindrical body 21, and two vertical grooves 21a on the lower part of the hollow cylindrical body 21.
A discharge port 21b communicating with 1a is formed.

Further, on the lower surface of the horizontal bait receiver 24, a plurality of protrusions, for example, four protrusions are provided radially, thereby forming four protrusions 24a on the lower surface of the outer edge of the horizontal bait receiver 24.

When using the above-described feeder 1, first attach the feed holder 2 to the small diameter shaft portion 14c of the boss portion 14 of the feed tank 10.
0 is fitted so as to be vertically movable and rotatable, and its lower end is abutted and supported by the stepped portion 14b. Next, hoppa 30
The shaft 15 is inserted into the insertion hole 34 formed in the stay 33 and supports the hopper 30 with the nut 17.
The male screw portion 15a of the boss portion 14 is inserted into the female screw hole 14a of the boss portion 14.
At the same time, the upper part of the bait holder 20 supported by the stepped portion 14b is inserted into the hopper 30 from the drop opening 32 so as to face the inside of the hopper 30.

At this time, the gap between the drop opening 32 of the hopper 30 and the horizontal feed receiver 24 is adjusted according to the condition of the feed and the amount of food ingested by the pig.

When bait is put into the hopper 30 in this state, the bait falls from the drop opening 32, is deposited on the horizontal bait receiver 24, and is also scattered in the food tank 10. Hotupa 3
When an appropriate amount of bait falls from zero, the bait is deposited in a column shape on the bait receiver 24, and the bait stops falling. In this state, the pigs can eat the food in the food tank 10 and the horizontal food receiver 24.

During the process of eating food, the pig's nose and mouth touch the horizontal feed receiver 2.
4, the bait holder 20 moves up and down,
In addition, the pig's nose and mouth are connected to the protrusion 24a of the horizontal feeding portion 24.
The bait holder 20 rotates by contacting the hopper 30, and due to this vertical movement and rotation, the bait accumulated on the horizontal bait holder 24 falls into the bait tank 10, and the bait is released horizontally from the drop opening 32 of the hopper 30. The bait receiver 24 is replenished as appropriate.

Furthermore, even if the bait solidifies near the drop opening 32 of the hopper 30, since the upper part of the bait holder 20 faces into the hopper 30 from the drop opening 32, it will not be affected by the vertical movement or rotation of the bait holder 20. The bait is scooped out from inside the hopper 30 and always supplied from the hopper 30 to the horizontal bait receiving part 24 and the feeding tank 10, preventing the bait from solidifying at the outlet of the hopper 30, and allowing a constant amount of bait to be fed at all times.

Furthermore, the bait holder 2 is inserted through the gap between the shaft 15 and the insertion hole 23 of the top plate 22 through which the shaft 15 passes.
Even if food gets into the feed tank 10, the entered feed is discharged into the feed tank 10 from the outlet 21b through the vertical groove 21a, and the vertical movement and rotational movement of the feed holder 20 can be maintained smoothly for a long period of time. .

Moreover, if the feed composition is changed during the growth process, the amount of feed replenished in one action of contacting the pig's snout changes depending on the viscosity, dryness, grain size, etc. of the feed.

Therefore, when the handle 15b is rotated in one direction,
The shaft 15 is fed upward and the hopper 30 is moved upward, increasing the distance between the food tank 10 and the hopper 30, thereby increasing the amount of food replenished into the horizontal food receiver 24. , If you want to reduce the amount of food to be replenished, turn the handle 15b in the opposite direction to the above.
All you have to do is turn the .

In this way, by adjusting the gap between the drop opening 32 of the hopper 30 and the horizontal feed receiver 24, the amount of feed can be easily controlled in accordance with the amount of food ingested by the pig.

Furthermore, a feeding tank 10, a feeding stand 20, a hopper 30
Since it can be easily disassembled, it is easy to clean, and as the pig grows, it is possible to initially use only the feeding tank 10, and when the pig grows to a certain extent, the feeding tank 10, feeding stand 20, and hopper 30 can be assembled and used. can.

For example, when the piglet is 0 to 3 days old and has started feeding, only the feeding tank 10 is used because the amount of food ingested by the piglet is small and there is no need to frequently replenish the food.

When the piglet grows up to about 14 days after birth, the amount of food it ingests increases and the frequency of replenishment increases. , the shaft 15 is attached to the feeding tank 10 and used.

When they reach the age of 21 to 23 days and grow up to weaning stage,
The handle 15b is rotated to adjust the amount of bait that comes out of the drop opening 32.

Therefore, there is no need to replace the feeder during the growth process of the pig, and the amount of feed replenishment and the amount falling into the feed tank can be easily adjusted, which reduces the labor of the breeder.

[Effect of idea]

As explained above, the pig feeder of the present invention has a boss portion in the feeding tank that has a small diameter cylindrical shaft portion formed in the upper part and a stepped portion approximately in the middle of the body, and a shaft provided with a hopper. , the hopper is vertically movable screwed into a boss part and stands upright, and a flange-shaped horizontal bait receiving part is provided approximately in the middle of the outer peripheral wall of a hollow cylindrical body having a top plate through which the shaft passes and having an open bottom. Since the formed bait holder is fitted into the small diameter shaft portion of the boss portion so as to be vertically movable and rotatable and supported by the stepped portion, the bait falling from the hopper is deposited on the horizontal bait holder portion. They are also placed in the food tank. When an appropriate amount of bait falls from the hopper, the bait is deposited in a column shape on the horizontal bait receiver, and the bait stops falling. In this state, the pigs can eat the food in the horizontal feed receiver or feed tank.

In addition, a bait holder having a horizontal bait holder with a plurality of protrusions formed on the lower surface of the outer edge is fitted into the boss part so that it can move up and down and rotate, and is supported by the stepped part of the boss part, so that the bait can be eaten easily. In the process, the feed tray moves up and down as the pig's nose and mouth come into contact with the horizontal feed tray, and
When the pig's nose and mouth come into contact with the protrusions on the horizontal feed receiver, the feed receiver rotates, and due to this vertical movement and rotation, the feed deposited on the horizontal feed receiver falls into the feeding tank, and the feed is removed. is replenished from the droplet of the hopper into the horizontal bait receiver as appropriate.

Furthermore, even if the bait solidifies near the drop opening of the hopper, the upper part of the bait pedestal supported by the step faces into the hopper from the drop opening, so it will not be affected by the vertical movement or rotation of the bait holder. Feed is drawn out from inside the hopper and constantly supplied from the hopper to the horizontal feed receiver or feeding tank, which prevents the bait from clumping at the outlet of the hopper and allows a constant amount of bait to be fed at all times.

Moreover, since the shaft provided with the hopper is screwed onto the boss part so that the hopper can move up and down, the gap between the drop opening of the hopper and the horizontal bait receiving part can be adjusted.
Feeding amount can be easily controlled according to intake amount.

Furthermore, an appropriate number of vertical grooves are formed on the inner circumferential wall of the bait holder, and a discharge port communicating with the vertical grooves is formed at the bottom, so that the bait can be removed from the gap between the shaft and the insertion hole in the top plate through which the shaft passes. Even if the bait gets into the cradle, the bait is discharged from the outlet through the vertical groove into the feeding tank, and the vertical and rotational movements of the bait cradle can be maintained smoothly for a long period of time.
