Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is installed in a fishpond or an ornamental fish tank,
The present invention relates to an automatic feeding device that can supply a fixed amount of food at a fixed time.

[Conventional technology]

Generally, it is difficult to supply fish bait quantitatively because of its high hygroscopicity and poor fluidity. Conventionally, a so-called projection type in which the bait is sprayed with a rotary wing is used. Further, as a device for removing powder or fluid, a rice bin used at home is known, which has a rotating bottom, and a predetermined amount of the rotating bottle is provided only when a hole provided in the rotating bottom coincides with an outlet. Rice is being extracted.

[Problems to be solved by the invention]

The projection type is not suitable for taking out a small amount of food, and it is difficult to accurately measure the amount of food.
In addition, when the rice bin is used as a feeding device, when the fish food absorbs moisture and becomes less fluid, it may stick to the feeding device and not fall by weight. Furthermore, since the taking out of the bait depends on its weight, there is a problem that the taking out amount of the bait varies depending on the storage amount.

The present invention has been made in order to eliminate such conventional drawbacks, and it is possible to reliably take out a desired amount of food by measuring the amount of food, and the amount of food taken out depending on the amount of storage. It is an object of the present invention to provide an automatic feeding device that does not change and that can be manufactured at a relatively low cost.

[Means for solving the problem]

This invention has a bait storage chamber formed in a cylindrical body,
A rotation driving means is provided on the lower side of the central portion of the bottom plate of the main body, and its rotation shaft extends upward through the main body bottom plate, and on the main body bottom plate, the stirring member is rotated by the rotation shaft and extends to the outer peripheral portion of the bottom plate. Is disposed in the vicinity of the bottom plate, an opening is formed in the peripheral wall of the main body in the portion in the vicinity of the bottom plate, a bait discharge passage is provided facing the opening, and the opening area of the opening is in the opening. A slide plate for increasing / decreasing the amount of food is arranged, an operation section for operating from outside the main body is formed on the slide plate, and a blower for ejecting the food in this passage to the outside is provided in the food discharge passage. .

[Action]

In the above configuration, the stirring member arranged at the bottom of the food storage chamber is rotated, whereby the food at the bottom of the storage chamber is sequentially sent out from the opening, and is ejected to the outside by the air blown from the blower through the food discharge passage. The amount of bait released can be measured by sliding the slide plate from the outside of the main body by the operation unit to increase or decrease the opening between the slide plates.

〔Example〕

1 to 4, a bait storage chamber 1a is formed in a cylindrical main body 1, and a lid 11 is attached to an upper opening of the bait storage chamber 1a to seal the inside. A motor (rotational drive means) 3 is provided below the central portion of the bottom plate 2 of the main body 1, and a rotary shaft 30 thereof extends through the main body bottom plate 2 and extends upward.
An adapter 4 is attached to the screw 30 with a screw 41, and a stirring member 5 is attached via the adapter 4. In this stirring member 5, peaks 50 and valleys 51 are alternately formed in the circumferential direction (four peaks and valleys in this embodiment), and the peaks 50 extend radially to the outer periphery of the bottom plate 2. Is formed so as to gradually increase toward the center of rotation, and the bottom surface of the stirring member 5 rotates while being substantially in contact with the top surface of the main body bottom plate 2.

The main body 1, the bottom plate 2 and the lid 11 are each made of a plastic plate material, and a core material 13 made of a heat insulating material such as a foam material is included in the center portion in the plate thickness direction.

An opening 10 is formed in the peripheral wall of the main body near the bottom plate 2, and a bait discharge passage 6 is provided so as to face the opening 10, and a blower is provided in the casing 71 above the bait discharge passage 6. (Bait releasing means) 7 is provided and its air injection port
70 is directed to the outlet 60 of the bait discharge passage 6.

A pair of slide plates 8 are provided in the opening 10 so as to face the opening 10.
The slide plate 8 is held slidably in the circumferential direction by the guide portions 61 on both sides of the food discharge passage 6. The bait discharge passage 6 is provided with a screw 63 at the periphery of the guide portion 61.
It is fixed to the main body 1 by. Also guide part 61
A guide hole 62 extending in the circumferential direction is formed in the slide plate 8, and a knob 9 is connected to the slide plate 8 by a shaft 90 thereof.
Movably penetrates through the guide hole 62. Although FIG. 3 shows only the configuration on one side, the other side is also configured symmetrically with this. Further, a small stirring member 81 is provided so as to project on the inner surface side of the slide plate 8 on the rear side in the rotation direction of the stirring member 5 (the direction of the arrow in FIG. 2).

The opening 80 that determines the amount of food taken out may be increased or decreased by sliding only one slide plate 8.

In the above configuration, in order to supply the bait to the fish tank or the like, the slide plate 8 is first slid by the knob (operation part) 9 with the predetermined bait in the bait storage chamber 1a and the lid 11 closed. An opening 80 having a predetermined size is formed between the slide plates 8. Then, the motor 3 and the blower 7 are driven.
When the motor 3 rotates, its rotating shaft 30 and the adapter 4
The rotating force is transmitted through the stirring member 5, the stirring member 5 rotates clockwise in FIG. 2, the stirring member 5 stirs the bait and pushes it in the radial direction, and the bait is discharged through the opening 10 and the opening 80 to release the bait 6 Supply inside. Then, in the discharge passage 6, the food is discharged and supplied to the fish tank or the like through the discharge port 60 by the air blown by the blower 7. At this time, the bait rotating near the outer periphery of the bottom of the bait storage chamber 1a is blocked by the small stirring member 81 and sequentially taken out through the opening 80. That is, as the stirring member 5 rotates, the bait at the bottom is gradually swirled from the center and is sent outward, and the bait at the outer periphery is blocked by the small stirring member 81 and sequentially opened 80.
Sent out from.

The amount of food released is determined by the rotation speed of the stirring member 5 and the opening area of the opening 80, and is not affected by the amount of food stored in the food storage chamber 1a. Therefore, by increasing or decreasing the opening 80 by operating the knob 9, it is possible to accurately weigh and discharge an arbitrary amount of food. Also the food storage room 1a
Since the bait inside is agitated by the agitating member 5 and sequentially released, the bait does not stay in a specific portion.

〔The invention's effect〕

As described above, according to the present invention, by rotating the stirring member arranged at the bottom of the food storage chamber, the food at the bottom of the storage chamber is sequentially sent out from the opening, and the food discharge passage by the air blown from the blower. Is released to the outside through.
The amount of bait released can be accurately measured by sliding the slide plate from the outside of the main body using the operation unit to increase or decrease the opening between the slide plates. Further, since the bait in the bait storage chamber is agitated by the agitating member and sequentially released from the bottom, the bait does not stay in a specific portion.
