Abstract

PROBLEM TO BE SOLVED: To provide a feeding device for preventing feed from being stuck inside a discharge route by moisture. SOLUTION: A rotary blade 4 disposed on the bottom surface of a hopper 2 for housing the feed is provided with a lid part 5, and when a position detection means detects that the lid part 5 is present at the position of closing a discharge port 3, a stopping means 14 stops a gear motor 8 for driving the rotary blade 4. When an operation is stopped, since the discharge port is closed by the lid part, the feed is prevented from falling down to the discharge route.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a feeding device for feeding cultured fish and the like.

[0002]

2. Description of the Related Art A conventional feeder of this type will be described with reference to FIG. 51 is a hopper for accommodating food, 52 is a rotating blade, 53 is a gear motor for rotating the rotating blade 52, 54
Is a discharge port, 55 is a discharge path, and 56 is a blower that blows air to the discharge path 55.

[0003] The blower 56 is started with the start of operation of the equipment, and then power is supplied to the gear motor 53. As a result, the rotating blades 52 operate, the bait collapses, and falls from the discharge port 54 to the discharge path 55. The fallen bait receives the wind pressure from the blower 56 and is discharged outside the machine. Thereafter, when a stop operation or the like is performed, the rotary blades 52 and the blower 56 stop,
Feeding is completed.

[0004]

In the above-mentioned feeder, the rotating blades 52 are stopped simultaneously with the operation stop operation. Therefore, in many cases, the discharge port 54 is open, and when there is vibration or the like, the food in the hopper 51 easily collapses into the discharge path 55. In general, there are many foods that easily absorb moisture. Therefore, the broken food is moist and sticks to the discharge path 55 as shown in FIG. 5, which hinders the blow-off of the food and hinders the feeding. further,
If food remains in the discharge path 55, there is a problem that pests and small animals may enter. The present invention has been made to solve such a problem.

[0005]

In order to achieve the above object, a feeder according to the present invention comprises a hopper for accommodating bait, a rotary blade provided on a bottom surface of the hopper, a gear motor for rotating the rotary blade, and a bait. Has a discharge port for discharging the outside of the hopper, a discharge path through which the bait discharged from the discharge port flows, and a blower that blows the discharge path, and a lid is provided on the rotary blade, and the lid is Position detection means for detecting that the discharge port is closed is provided, and stop means for stopping the gear motor based on the detection result of the position detection means is provided.

[0006]

According to this structure, the position detecting means detects that the lid is at the position at which the outlet is closed, and stops the gear motor. Therefore, when the operation is stopped, the outlet is in the closed state.
It is possible to prevent the food from collapsing into the discharge route.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a housing of a feeder, 2 denotes a hopper for accommodating granular or pellet-shaped food to be given to cultured fish and the like, 3 denotes a discharge port provided on the bottom surface of the hopper 2, and 4 denotes a rotation. It is a feather. The rotary blade 4 is provided with a ribbon-shaped lid 5 for closing the discharge port 3 as shown in an exploded view of FIG. Here, the lid portion 5 has a ribbon shape, but is not limited to this shape. A magnet 6 is provided at one end of the lid 5, and a reed switch 7 is provided on the bottom surface of the hopper 2 as a position detecting means that is turned on / off by the magnet 6.

A gear motor 8 for rotating the rotary blades 4;
Reference numeral 9 denotes a discharge path, and the discharge path 9 communicates with the discharge port 3 through a vertical passage 10. A blower 11 is provided at one end of the discharge path 9, and a discharge port 12 at the other end is slightly projected outside the housing 1 and opened. A control unit 13 controls the operation of the electrical components.
Various means are provided, such as a stopping means 14 for stopping power supply to the gear motor 8 when is turned on. Incidentally, the stopping means 14 and the like are actually constituted by a microcomputer.

Next, the operation of the above configuration will be described. Feed is stored in the hopper 2, and in this state, when an operation switch (not shown) is operated, or when a set timer time comes, the operation is started and the blower 11 is started. After a short time, when the blowing amount of the blower 11 is sufficiently increased, power is supplied to the gear motor 8 and the rotating blades 4 start rotating. Therefore, the food in the hopper 2 is discharged little by little into the outlet 3.
, Falls into the discharge path 9, is blown off by the wind pressure,
The liquid is discharged from the discharge port 12 to the outside of the housing 1 vigorously.

When the feeding is continued for a predetermined time or when the stop switch is operated, a stop operation is performed. Regarding the operation stop operation, when the side of the lid 5 that rotates together with the rotary blade 4 without the magnet 6 comes to a position covering the entire discharge port 3, the reed switch 7 changes from OFF to ON. Stop means 14 stops power supply to the gear motor 8. That is, since the rotating blades 4 always stop at a predetermined position that closes the discharge port 3, the bait in the hopper 2 is discharged from the discharge path 9 even after receiving vibration or the like.
Can be completely prevented from falling.

[0011] Even after the rotating blades 4 stop, the blower 11 continues to be driven for a while. This is to completely discharge the bait in the discharge path 9. As a result, the blower 11 stops and the operation is stopped. However, as described above, the bait does not collapse into the discharge path 9, so that it is possible to effectively prevent the bait from becoming wet and hindering the next feeding. You.

[0012]

As described above, the feeder of the present invention is provided with a cover on the rotating blades rotated by the gear motor, and with the position detecting means for detecting that the cover is in the position to close the discharge port. And stopping means for stopping the gear motor based on the detection result of the position detecting means. Therefore, the operation of the device is stopped with the lid closing the outlet, preventing the food from collapsing from the outlet to the discharge path, preventing the food from getting wet, pests and small animals entering. It has an excellent effect that normal feeding can be performed for a long time.
