Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a spreader for a feeder. More specifically, the present invention relates to a spreader that is provided in a feeder for feeding mainly to a seafood farm and that disperses the feed evenly.

[0002]

2. Description of the Prior Art Spreaders for feeders are roughly classified into the following two types. That is, (A) a type in which a blower is used to spread bait by the wind pressure (hereinafter referred to as a blower type), and (B) as shown in FIG. 3, a large number of blades 51 (usually 6 blades) are radiated from the center thereof. The above-mentioned) is used, and the bait dropped on the bait is scattered by the centrifugal force by the rotation of the disk and the striking action of the blades 51 (hereinafter referred to as the disk type). 53.

[0003]

The blower type diffuser is the most widely used at present. Since the bait is sprayed by wind pressure, the bait particles can be blown relatively far (about 4 meters) without being broken, but there is a drawback in that the spray angle is narrowed. In addition, a blower with a large output is required (power consumption is about 150 to 400 watts), so it cannot be practically used in places where a battery must be used as a power source, such as at sea. In addition, when spraying large-grained baits (for example, with a diameter of about 4 mm or more), a blower with a larger output is required, so it is mainly used for baits with a smaller grain size (for example, with a diameter of about 3 mm or less). It is the current situation.

As described above, the blower type spreader is not only limited in the grain size of the bait to which it is applied, but also high in cost and has many failures. In particular, since the feeder is installed on the aquaculture ground, it often inhales air containing a large amount of moisture, and often causes problems such as corrosion of the blower and electric leakage.

On the other hand, although the disk type diffuser cannot fly bait far, it has a wide spraying angle, so that the spreading area is wide and it is possible to feed many fish evenly.
As a result, feeding efficiency is slightly better than that of the blower type. On the other hand, bait that is cracked or pulverized causes poor bait efficiency, and the pulverized bait may attach to rotating discs or feathers and spoil it, giving off a bad odor or impairing fish health. ..

As a result of various investigations, the inventor of the present application has found out that the problem of the disk type spreader that the bait does not fly far away and the bait is powdered as described above is due to the following causes. .. That is, the bait that has fallen onto the disk rolls in all directions on the disk, and because the baits collide with each other and the blades many times, they break or become powdered.

Since the bait rotates together with the disc, the impact effect of the blades, that is, the effect of flying far away is weakened, and the bait does not fly far because it depends largely on the scattering by the centrifugal force of the disc.

As described above, the scattering of the bait depends largely on the centrifugal force, so that the blade is required to have a character as a guide for the scattering of the bait, and as a result, the number of the blades is increased and the impact effect of the blades is further improved. descend. As a result, the flight distance of bait is further shortened.

The present invention has been made to solve the above problems, and provides a spreader capable of suppressing the cracking and pulverization of the bait and flying the bait far with a wide spread angle. The purpose is to do. It is also an object of the present invention to provide a diffuser capable of producing such an effect with a smaller power.

[0010]

The spreader for a feeder according to the present invention is provided with a housing having a floor surface on which the fed food is placed, and a floor surface by rotating on the floor surface. It is composed of a blade for hitting the placed bait and a drive unit for rotationally driving the blade.

In the diffuser, it is preferable that at least four blades are formed.

Further, it is preferable that the blade has a striking surface for striking the bait which forms an obtuse angle with the floor surface of the housing.

In order to surely prevent the crushing of the bait,
It is preferable to provide a cushioning material on the striking surface.

[0014]

In the spreader of the present invention, since the bait that falls into the housing and is placed on the floor of the housing, so to speak, is blown by the blades to be scattered, the conventional disk-type spreader is used. Compared with this, the impact effect is far greater. Therefore, the bait is blown away while maintaining a wide spread angle. Then, since the bait is hit by the blades only once, cracking and pulverization are well suppressed. Moreover, since only the blades can be rotated by the drive unit, a drive device having a much smaller output is used as compared with the above-mentioned disk type diffuser which also rotates the disk integrally as well as the blower type diffuser. be able to. As a result, both the manufacturing cost and the movement cost of the spreader are reduced. Furthermore, using the battery, it can be used safely at sea. By appropriately reducing the number of blades, it is possible to employ a driving device having a smaller output.

On the other hand, the flight distance of the bait can be changed by changing the striking surface angle of the blade with respect to the floor surface of the housing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a spreader of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an embodiment of the spreader of the present invention, and FIG. 2 is an explanatory view showing the spreader of FIG. 1 mounted in a feeder.

In FIG. 2, reference numeral 1 is a spreader mounted inside the feeder 2. The bait F filled in the feeding hopper 3 in the feeder 2 is fed to the lower spreader 1 via the feeding pipe 5 by the feeding mechanism 4 at the bottom of the hopper 3. The fed bait F is scattered from the feeding port 7 to the outside by the rotary blades 6 in the diffuser 1. The rotary vane 6 is rotated by a drive unit 8 including a motor.

As shown in FIG. 1, the diffuser 1 includes a housing 9 and the rotary vanes 6 disposed in the housing 9.
And the drive unit 8.

The housing 9 has a substantially U shape, and U
The opening of the letter forms the feeding port 7. An output shaft in which two rotary vanes 6 project through the floor surface 10 of the housing 9
It is fixed at 11. The output shaft 11 projects at the center of the U-shaped semicircular portion of the floor surface 10. And the rotary blade 6
Has a very small gap between its tip and the side wall 12 of the housing 9, and its bottom edge is on the floor surface.
It is configured to rotate while forming a very small gap with 10.

In FIG. 1, the rotary blade 6 is adapted to rotate in the direction of arrow A, and the surface of the side on which the bait F is hit (hereinafter, hit surface) forms an obtuse angle with the floor surface 10. ing. That is, the striking surface faces slightly upward from the vertical direction so that the bait F can be moved further away.

In the present invention, the hitting surface is not particularly limited to the one tilted upward, but it is preferable to point it slightly upward so as to extend the flight distance of the bait.

Further, it is preferable to provide a mechanism capable of changing the rotation speed of the rotary blade 6.

Although two rotary vanes 6 are attached in this embodiment, the number of rotary vanes 6 is not particularly limited to two in the present invention, and one or more or any number may be used. However, it is preferable to reduce the number of baits to 2 to 4 in order to efficiently disperse the bait by one hit of the rotary blades 6 and to suppress the vibration. Then, by reducing the number of blades in this way, it is possible to employ a driving device having an extremely small output. For example, it has been proved that by using two rotary vanes 6, a motor having a rated output of 4 W can be used, and as a result, the bait can fly to a distance of 5 to 7 meters.

Further, it has been proved that the batting can be prevented further by lining the striking surface of the rotary blade 6 with rubber or the like.

As described above, in the present diffuser 1, the rotor is only the rotary blades 6 (does not have a disk), and the number of blades is smaller than that of the conventional disk diffuser 53,
Also, the structure is much simpler than that of the blower type, so that the output of the drive unit is small, there are few failures, and there is almost no adhesion of food. As a result, both the manufacturing cost and the operating cost are extremely low compared with the conventional spreader.

[0027]

EFFECTS OF THE INVENTION The spreader of the present invention is capable of scattering bait in a wide range while suppressing its cracking and pulverization, has a simple structure, and can employ a drive device of small output. , The manufacturing cost and the operating cost are extremely low.
