Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automatic feeding device for feeding rabbits, guinea pigs and the like.

(Prior Art) A conventional feeding device is one in which a container for putting food has a drum shape having an opening, and the drum makes one rotation to feed the food from the opening portion (actually, KOKAI Sho 50-45281).
No., Jitsukai Sho 58-35852, etc.), or a box type with a shutter-type outlet.

(Problems to be solved by the invention) In the conventional feeding device, when the drum type is used, when the drum rotates when the food is discharged into the take-out port, the sliding part is clogged with the food and the rotation of the drum is hindered. There was a problem that automatic feeding could not be done.

Further, in the case of the shutter type, there is a drawback that the food is caught during the opening and closing of the shutter and feeding becomes impossible.

An object of the present invention is to solve the above-mentioned problems and to provide a device in which food is not clogged between the drum and the device body.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, the bait is dropped from the delivery port provided at the bottom of the bait container into the bait discharge container, and when the timer is set, the food discharge container is reached. In an automatic feeding device for feeding food by rotating by a motor, the food discharging container has a semi-cylindrical shape having a recess, and both ends thereof are closed by outer walls, and further, the food discharging container is rotated to feed food. After being dropped from the concave portion, a reversing mechanism for reversing the food discharge container without rotating it once was provided.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The feeding device of the embodiment is, for example, a device for automatically feeding the food to be eaten by rabbits and guinea pigs in the breeding cage,
1 is a schematic perspective view of the apparatus, FIG. 2 is a partial cross-sectional perspective view of a food discharging container which is a part of the feeding apparatus, and FIG. 3 is a plan view of the apparatus.

The feeding device according to the present embodiment includes a food container 1 and a food discharge container 2.
And a food receiving container 3. Wheels 4 and 5 are provided at the bottom of the food container 1 (Fig. 1), and wheels 4 and 5 are provided.
The discharge container 2 is rotatably attached between the and.
Grooves 1a, 1b (Fig. 2) are formed in the food container 1 and the frames 3a, 3b (Fig. 1) of the food receiving container 3 are inserted into these grooves to connect them. Further, a fixing rod 24 is provided on the upper part of the food receiving container 3, and this rod 24 is sandwiched by fixing tools 25a and 25b attached to the side surface of the food receiving container 1 so that the food receiving container 1 is separated from the food receiving container 3. I try not to come off.

The bait discharging container 2 is a semi-cylindrical container having a recess 2a, and disk-shaped outer walls 4a and 5a are fixed to both ends of the bait discharging container 2, and both ends of the bait discharging container 2 are slidable in wheels 4 and 5. It is movably attached. The food discharge container 2 has a recess 2a for the food container 1
It is arranged so as to face the distribution port 1c of the
Figure). The recess 2a is formed along the longitudinal direction of the bait discharge container 2 with edges 2b, 2
have c.

As shown in FIG. 2, an outer claw 6 protruding toward the inner side of the wheel 4 is attached to the inner side of the wheel 4, and a claw rotating plate 8 is rotatably attached to a shaft 19 on the outer wall 4a. . Claw rotating plate 8
Is urged clockwise by a spring 7. A main shaft 16 of a motor 15 is inserted through the center of the outer wall 4a, and a claw 17 is attached to the tip of the main shaft 16 with a screw 18. The pawl rotating plate 8 has two abutting portions, that is, a portion that abuts the pawl 17 and a portion that abuts the outer pawl 6.

On the other hand, a groove 5b is formed inside the ring 5, and a spring 20 is embedded in the groove 5b. One end of the spring 20 is fixed to the wheel 5 by a screw fixing tool 9, and the other end is fixed to the outer wall 5a by a screw 27. A shaft 10 is provided at the center of the outer wall 5a, and the shaft 10 is attached to a hole 11 formed in the food container 1. On the shaft 10, as shown in FIG.
The disk 13 has a protrusion 12 fixed thereto. Protrusion
A switch 21 is provided at a position where 12 contacts, and this switch 21 is connected to a timer 23. The timer 23 is for supplying power to the motor 15 at a desired time, and this power supply is controlled by a signal from the switch 21.

Next, the operation of the above device will be described.

First, the bait discharge container 2 stores the bait dropped from the distribution port 1c. When the time set by the timer 23 is reached, the motor 15 is driven and the pawl 17 fixed to the main shaft 16 rotates clockwise in FIG. 2 to abut on one abutting portion of the pawl rotating plate 8 to rotate the pawl. The plate 8 is pushed, which causes the bait discharge container 2 to rotate clockwise in FIG. 2 against the pulling force of the spring 20. When the other contact portion of the claw rotating plate 8 contacts the claw 6, the claw rotating plate 8 rotates counterclockwise against the force of the spring 7, and the claw rotating plate 8 rotates.
The engagement with 17 is released, and the rotating force of the motor 15 causes the bait discharge container 2 to rotate.
Will not be transmitted to. Then, the food discharge container 2 is pulled to the original position by the restoring force of the spring 20 and rotates in the reverse direction.

The timing at which the food discharge container 2 is reversed is when the food discharge container 2 rotates and reaches the position indicated by the chain line, as shown in FIG. At this position, the food in the food discharge container 2 has fallen into the food receiving container 3.

When the food discharge container 2 rotates in the reverse direction, the disk 13 also rotates in the reverse direction, the protrusion 12 pushes the switch 21, and the rotation of the motor 15 is stopped. The switch 21 also serves as a stopper for the disc 13.

In the conventional device, as illustrated in FIG. 4, the bait discharging device 2 rotates once, and at this time, the rim 2b of the bait discharging container holds the bait between the rim 1e of the delivery port of the bait container 1. I will end up. This is the cause of food clogging.

However, according to the device according to the present invention, when the bait discharging device 2 rotates halfway, the bait can be dropped and discharged, and the edge 2b of the food discharging container 2 is reversed before reaching the edge 1e of the food container 1. Therefore, it is possible to reliably feed the bait, because the bait does not get caught in this part as in the conventional device. Further, in the above device, since the spring 20 is used for reversing the bait discharging container 2, the container 2 quickly returns to its original position, so that bait can be prevented from spilling from the bait container 1 to the bait receiving container 3. . In addition, the spring 20
Since it uses, the momentum to return to the original position is strong, so the axis
A large vibration is applied to the food container 1 through the switch 21, which also functions as a stopper for the disks 12 and 13, and the next food is rapidly supplied to the food discharge container 2 without being stagnant in the vicinity of the distribution port 1c. .

(Effect of Device) As described above, according to the device of claim 1, it is possible to reliably feed food without causing food clogging between the food discharge container and the food container. According to the second aspect of the present invention, in addition to the above, it is possible to prevent the bait from spilling from the bait container, and to vibrate the bait container 2 so that the bait can be supplied smoothly.
