Abstract

PURPOSE:To make the bottom rotor disk high on its periphery by 1 step to form a narrow gap between the periphery and the downward projection of the top-cut cone at the bottom of the bait box whereby the rotor disk operates smoothly. CONSTITUTION:In a feed box for fish cultivation, a face 5c inclined inward from the periphery is formed as a part of the an inverted cone on the upper periphery of the rotor disk 5 with a feeding hole 5a corresponding to the bottom of the cylindrical feed box 2. Opposing to the face 5c, the largest diameter part 2c is formed at the bottom of the box to form a downward projection of the top-cut cone at the step. The feed for fish on the rotor disk can be prevented from coming into the gap between the inner surface of the box and the rotor disk.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an automatic feeding device that is installed in a fish pond or ornamental fish tank and is capable of supplying a fixed amount of food at a fixed time. A rotary bottom plate is provided on the bottom surface, and only when a bait exit hole provided on the bottom plate matches a bait receiving hole provided below the rotating bottom plate, bait K passes through the bottom plate and is fed to the aquarium.

[Conventional technology]

The applicant previously proposed a cylindrical rotary automatic feeding device that is suitable for being installed in a fish tank and feeding a predetermined amount of fish food at a fixed time (Japanese Patent Application No. 62-248159). This is a system in which a cylindrical feeding box and a machine box are separably fitted together, and the rotating bottom plate, which forms the bottom of the feeding box, is fully supported by the dividing plate sandwiched between them. The hole is designed so that the bait passes through the hole and is fed into the aquarium only when the bait outlet hole and the bait receiving hole provided below are aligned.

[Problem that the invention seeks to solve]

However, when feeding boxes are equipped with a rotating bottom plate, the fish tank is inserted between the inner surface of the feeding box and the rotating bottom plate, and when used for a long period of time, it solidifies and the rotating bottom plate becomes smooth. There was a problem that made rotation difficult.

[Means for solving problems]

This invention was made with the aim of eliminating such problems and allowing the rotating bottom plate to operate smoothly over a long period of time.The invention is made with the aim of eliminating such problems and ensuring smooth operation of the rotating bottom plate over a long period of time. The upper surface of the partition plate supports a rotating bottom plate arranged concentrically with the inner circumferential surface of the bait box, and the lower surface supports a motor connected to the rotating bottom plate. In addition, a bait receiving hole corresponding to the bait outlet hole is formed in the partition plate, and a bait take-out pipe is connected to the bottom surface of the bait receiving hole, while a large diameter part is formed at the lower end of the cylindrical feeding box. A truncated conical downward protrusion is formed on the stepped portion thereof, and a cone-shaped inclined surface with a concave inner surface is formed on the periphery of the rotary bottom plate, and the inclined surface faces the downward protrusion. There are characteristics.

[Effect]

The fish food placed in the feeding box is deposited on the rotating bottom plate, slides downward along a mortar-shaped slope formed on the top surface, and is fed through the bait outlet. At that time, the fish bait descends from above the feeding box and slides toward the bait hole along the mortar-shaped slope on the upper surface of the rotating bottom plate, but the periphery of the rotating bottom plate is higher. A narrow space formed between the bait box and the truncated conical downward projection provided at the lower end of the bait box prevents the fish bait from reaching the periphery of the rotary bottom plate.

〔Example〕

Hereinafter, the present invention will be explained with reference to the illustrated embodiment. In the figure, 1 is an automatic feeding device according to the present invention, which is composed of a cylindrical feeding box 2 and a mechanical box 3 that are fitted in a vertically separable manner. ing. The feeding box 2 and the machine box 3 are made of transparent synthetic resin such as acrylic or heat-insulating synthetic resin such as styrofoam, and there is a connecting part A that connects them.
The small diameter outer surface formed at the upper end of the machine box 3 is tightly fitted into the large diameter inner surface formed at the lower end of the bait box 2. That is, at the lower end of the feeding box 2, which forms the outer surface, there is formed a 2 m long reed (2 meters shorter than the length of the upper end), and the outer surface of the upper end of the machine box 3, which is made to have a slightly larger diameter than the inner diameter of the reed, is The feed box is fitted firmly enough that it can be inserted and removed, and even if rain or water drops run down the outside of the feed box, it will not get inside.

Reference numeral 4 denotes a disc-shaped synthetic resin partition plate sandwiched between the boxes 2 and 3 to partition the bait box 2 and the machine box 3. A rotating bottom plate 5, which forms the bottom surface of the feeding box 2, is provided on the upper surface of the partition plate 4 in contact with the feeding box 2, and an electric motor 6 for driving this is bolted to the lower surface. The feeding box 2 itself is made up of two members, a relatively small-diameter cylindrical portion 2b and a large-diameter cylindrical portion 2c, which are fitted together and glued together. It is said to be a pointed, truncated, conical, downward-pointing projection.

In addition, the small diameter cylindrical part 2b is connected to the auxiliary cylinder B in the same manner as the connecting part A, and by preparing several auxiliary cylinders B of different lengths, the capacity of the feeding box 2 can be reduced. It is designed to be adjustable in size. Reference numeral 7 denotes a lid placed on the upper opening of the feeding box 2 to close it.

The rotary bottom plate 5 has a bait outlet hole 5a opened at a position slightly away from the axis of rotation, and correspondingly, the bait outlet hole 5a is formed in the partition plate 4 to have a slightly larger diameter or a downwardly-opening tapered shape. One bait receiving hole 4a is opened, and the fish bait will fall through it only when both holes 5m and 4m are aligned. The rotating bottom plate 5 has a conical protrusion 5b in the center and a protrusion 5c on the outer periphery consisting of a sloped surface with a raised outer surface. The opening is made to allow the fish bait to fall smoothly into the bait outlet hole 5a.

Further, the upper surface of the outer end of the annular projecting edge 5c is connected to the small diameter cylindrical portion 2.
A narrow gap facing upward is formed facing the conical surface provided at c, thereby preventing the feed in the feeding box 2 from falling into the gap 5d between the lower cylindrical portion 2c and the rotating bottom plate 5. There is.

8 is a bait take-out pipe υ, which is a bait receiving hole 4a provided in the partition plate 4.
It is made of rubber-like synthetic resin and consists of a vertical section 8a and an air blowing section 8b connected to the vertical section 8a.

One end of the blower section 8b is connected to the blower 9, and the other end is opened to the outside through the wall of the machine box 3, so that the fish bait falling from the vertical section B& can be prevented from being stagnated by the air blown from the blower 9. It is designed to be discharged to the outside. In addition, 3a
3b is the air intake port of the blower 9 provided on the wall of the machine box 3;
is the bottom plate of the machine box 3, and the blower 9 is bolted to it.

Note that this feeding device is not necessarily limited to use in fish tanks, but can also be used for dogs and tubes.

Next, the operation of this automatic feeding device 1 will be explained.

First, granular or powdered feed is put into the feeding box 2 and the power is turned on. After a predetermined period of time has elapsed or at a predetermined time, the timer switch operates and 'r!' is activated for the set time. Electricity is applied to the LfIh machine 6 and the blower 9. As a result, the counter-rotating bottom plate 5 rotates, and during the period when its oblique outlet hole 5a and the feed receiving hole 4a of the partition plate 4 are aligned, the feed falls into the lower take-out pipe 8 and is carried outside by the blower 9. It is blown out and falls into a live fish tank (not shown).

〔Effect of the invention〕

As described above, this invention forms a mortar-shaped inclined surface with a concave inner surface on the upper surface periphery of a rotary bottom plate provided with an oblique exit hole that forms the bottom of a cylindrical feeding box, and a cylindrical feeding box corresponding to this A large-diameter portion is formed at the lower end, and a downward protrusion in the shape of a truncated cone is formed at the stepped portion to face the inclined surface, so that the fish bait placed on the rotating bottom plate can be transferred to the inner surface of the feeding box. This has the effect of preventing it from entering the gap between the base plate and the rotating bottom plate.
