Abstract

PURPOSE: To provide a weighing apparatus for feeding, capable of smoothly cutting feed without causing clogging of feed and enabling feeding of a small amount of bait per time. CONSTITUTION: A discharge pipe 2 connecting to a funnel-like hopper is brought into contact with a disc face of a vertical disc 4 oscillated by a prescribed angle by a rotary solenoid 3 having a horizontal rotating shaft and a weighing pocket 7 is provided on the disc face. Thereby, a definite amount of feed is charged from the discharge pipe 2 to the weighing pocket 7 and a definite amount of feed made to flow into the weighing pocket 7 is released and fed to the downward direction when the disc is rotated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic feeding device mounted on a feeding cage for aquaculture cages or marine farms.

[0002]

2. Description of the Related Art Conventionally, as an automatic feeding method for aquaculture cages, generally, as shown in FIG. 6, a feeding rotary cup is provided corresponding to a discharge port of a hopper for accommodating the bait, As shown in (A) to (B) of the figure, a motor is used to rotate 180 ° to disperse a fixed amount of food, or the shutter type weighing shown in Japanese Patent Application No. 62-144940. The device has been used.

[0003]

According to the conventional method, it is difficult to smoothly cut the bait due to the downward pressure of the bait outlet and the pressure of the bait from above. If you try to lower it, the cross-sectional area of the discharge pipe will become narrow, which will cause food jams, making it difficult to throw small amounts of food.

[0004] The present invention overcomes the above-mentioned disadvantages of the prior art,
The feeding metering device enables smooth feeding cutting, can feed a small amount at a time, and can easily change the feeding amount.

[0005]

In order to achieve this object, in the present invention, the pressure of the bait from above is made to escape by making the bait cutout sideways to reduce the density of the bait in the bait cutting part and Make it happen smoothly.

For this purpose, the discharge pipe following the funnel-shaped hopper is brought into contact with the disk surface of a vertical disk which is swung by a rotary solenoid having a horizontal axis of rotation by a predetermined angle, and a measuring pocket is provided on the disk surface. A fixed amount of food is allowed to flow from the discharge pipe into the measuring pocket, and when the disc is rotated by a predetermined angle, the fixed amount of food which has flowed into the measuring pocket is thrown downward.

Further, it is possible to change the feeding amount by providing measuring pockets having different capacities on both sides of the vertical disk and changing the surface of the disk contacting the discharge pipe following the funnel-shaped hopper.

Further, it is possible to provide a plurality of measuring pockets having a plurality of capacities on the surface of the disk and change the mounting position of the disk to change the measuring pocket to be used.

By providing a striking mallet driven by a rotary solenoid for impact-vibrating the discharge pipe portion following the funnel-shaped hopper, a bridge or the like is prevented from occurring in the discharge pipe portion.

[0010]

[Function] Since the bait outlet is oriented laterally, the bait pressure is not applied from above, so the bait density at the bait cutting part can be reduced, the bait can be cut smoothly, and the feeding amount can be increased. Is determined by the capacity of the measuring pocket provided on the disc and is not related to the cross-sectional area of the discharge pipe, so it is possible to feed small amounts.

By changing the surface of the disk contacting the discharge pipe, the disk surface to be used of the vertical disk provided with the measuring pockets having different capacities on both surfaces is selected, and the mounting position of the disk is changed. Thus, the weighing pocket to be used can be selected from the weighing pockets having a plurality of capacities provided on each disc, and the feeding amount per serving can be changed.

By providing a hammer with which the discharge pipe portion following the funnel-shaped hopper is impacted and vibrated, the discharge pipe portion can be cut smoothly without causing a bridge or the like, and the hammer can be driven by rocking a disc. It can also be used as a rotary solenoid.

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

FIG. 1 is a partially cut front view showing an example of a feeding apparatus embodying the present invention. In the figure, 1 is a funnel hopper, 2 is a discharge pipe, 3 is a rotary solenoid, 4 is a vertical disc, and 5 is a circle. A plate cover and 6 are feeding tubes. The discharge pipe 2 comes into contact with the vertical disc 4 through the disc cover opening 5a, and the bait filled in the funnel-shaped hopper 1 is discharged through the discharge pipe 2 and the disc cover opening 5.
It is supplied to the vertical disc 4 through a, and every time the vertical disc 4 is swung by the rotary solenoid 3 at a predetermined angle, the bait is cut out in a fixed amount and fed through the bait barrel 6.

FIGS. 2 and 3 are explanatory views showing the weighing device for feeding according to the present invention, and 7 is a weighing pocket. Figure 3 (A)
2 shows a cross-section AA of FIG. 2, showing a state in which the bait flows from the discharge pipe 2 into the weighing pocket 7 through the disc cover opening 5a.

FIG. 3B shows a rotary solenoid 3 which moves the vertical disk 4 at a predetermined angle (4 in this example) from the above state (A).
5 °) showing a state of rotation, blocking the inflow of food from the discharge pipe 2 into the measuring pocket 7, and passing through the clearance 5b provided between the vertical disc 4 and the disc cover 5 to the inside of the measuring pocket 7. The food is discharged downward and thrown.

The vertical disc 4 is swung by the rotary solenoid 3, and the state shown in FIGS. 3 (A) and 3 (B) is alternately repeated to perform the metering and feeding. The weighing pocket 7 is set to a shape that is convenient for quantitatively holding the bait in (A) and for discharging and feeding the held bait in (B). FIG. 3 shows an example in which measuring pockets 7 are provided at three locations on the vertical disc 4.

A hammer 8 is attached to the rotary shaft of the rotary solenoid shown in FIG. 3, and when the vertical disc 4 is swung, the discharge pipe 2 is shock-excited and the funnel-shaped hopper 1 or the discharge pipe is used. 2 shows an example in which a bridge is prevented from occurring and the bait is smoothly cut.

FIG. 4 shows an example in which measuring pockets 7b, 7c and 7d having different capacities are provided at three locations on the vertical disc 4, and FIG. 5 shows an example in which the measuring pockets 7 are provided on both sides of the vertical disc 4. Indicates. The mounting position of the vertical disc is changed according to the required feeding amount, and the weighing pocket 7 to be used is selected.
