Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic feeding device that performs periodic automatic feeding over a plurality of times.

Conventionally, a large number of devices have been devised and manufactured that automatically perform feeding once in one feeding, and these devices have been put into practical use for testing and research purposes or for use in the stock farming industry.

As shown in Figure 1a, the basic method of these devices is that feed is supplied in advance to a feed holding container 1 with the lid 2 open, and when feeding time comes, the bottom plate 3 is automatically opened. Alternatively, as shown in Fig. 1b, the feed is supplied to the feed tank 4 in advance and the animals 6 are fed at feeding time. There is a method that automatically pulls up the shield 5 that has been preventing foraging.

Note that in either case, the power source of the drive device is an electromagnetic coil (solenoid) or a motor.

However, in these conventional feeding devices, the feed holding container 1 or feed tank 4 must be replenished with feed each time feeding is performed, so the effects of automation are not so great.

Therefore, a method has been proposed in which multiple devices shown in Figure 1 are simply lined up in order to perform automatic feeding multiple times, but this method requires as many power sources as the number of devices lined up. Furthermore, there are problems in that it takes up a lot of space and is expensive.

On the other hand, as another method for performing automatic feeding multiple times, the methods shown in FIGS. 2 and 3 have been proposed.

In the systems shown in FIGS. 2a and 2b, the cylindrical feed holding container 1 is divided into radial sections, and the partition plate 7 is rotated by a certain angle at predetermined time intervals to supply water through the opening of the feed holding container. keep

Note that FIG. 2a shows a case where the rotational axis of the partition plate 7 is horizontal, and FIG. 2b shows a case where the rotational axis of the partitioning plate 7 is vertical.

In addition, in the method shown in FIG.
Feed is fed through the opening 10 by moving the feed holding container 1 divided by 1 in a straight line on the bottom plate 9 having the opening 10.

However, in the conventional systems shown in Figs. 2 and 3, automatic feeding can be performed multiple times using a single power source, but the mechanism is complicated and the entire device becomes large. There is a problem in that the entire feed in the container 1 must be driven, which requires a large driving force and strength.

The present invention aims to solve these problems, and uses a simple mechanism to reduce and simplify the driving part for feeding, thereby improving the feeding management.
The purpose is to provide an automatic feeding device with a wide range of applications.

For this reason, the automatic feeding device of the present invention is provided with a feed holding container which integrally has a plurality of feed holding chambers arranged in tandem, each having an opening/closing door pivotally connected at one end to the bottom, and through each of the opening/closing doors. A single animal feeding tank is provided below each of the above-mentioned feed holding chambers to receive feed, and an automatic door opening mechanism is provided to sequentially open each of the above-mentioned doors. An automatic opening mechanism is provided with a locking part that is provided at equal intervals a in the feed holding container and can keep each of the opening/closing doors closed, and a locking part that is provided along the feed holding container with a single drive by a motor for a distance b ( <
a push rod that advances by a); an unlocking section provided on the push rod at equal intervals (a-b) to engage the locking section and open the opening/closing door; and the motor periodically It is characterized by comprising a clock means for operating the clock.

An automatic feeding device as an embodiment of the present invention will be described below with reference to the drawings. FIG. 4 is an exploded perspective view showing its overall configuration, FIG. Fig. 6 is a partially cutaway plan view of the main part, Fig. 7 is a partially cutaway front view of the main part, and Fig. 8 is for explaining the operation of the automatic door opening mechanism. FIG. 9 is an electric circuit diagram for driving the motor.

As shown in FIGS. 4 to 7, a feed holding container inner box 11 into which a partition plate 7 is fitted can be freely inserted into a feed holding container 1 having a lid 2. A plurality of feed holding chambers 1' are integrally formed in tandem.

One end of an opening/closing door 12 is pivotally attached to the bottom of each feed holding chamber 1', and in order to supply feed to the breeding animals 6 through each opening/closing door 12, a door is provided below each feed holding chamber 1'. A single animal feeding tank 4 is installed via a hopper 4'.

Further, an automatic door opening mechanism A that sequentially opens each door 12 is provided. A plurality of opening/closing door fixing hooks 13 as locking parts are engaged and pivotally connected to the feed holding container 1 via pins, and the hooks 13 and the protrusions are connected by engaging with these hooks 13 and rotating the hooks 13 respectively. A push rod 14 having an opening/closing door opening protrusion 15 as an unlocking portion for releasing the engagement with the shaped engaging portion 12', and a push rod 14 that is driven along the feed holding container 1 and installed in the feed holding container 1. A drive circuit C having a gear reduction motor 16 and a timing means for periodically operating the motor 16 (see FIG. 9).
It is made up of.

Furthermore, the push rod 1 is driven by the gear reduction motor 16.
4, a drive protrusion 18 is attached to the motor 16 to drive the motor 16.
A drive wheel 17 is provided, and a rack 20 engages with the drive protrusion 18 to drive the push rod 14.
is provided on the push rod 14, and the motor 16 is
In order to operate only the rotation, the feed holding container 1 is provided with a limit switch 19 which is driven by the drive protrusion 18 to open and close the drive circuit C of the motor 16.

On the other hand, as shown in FIG.
It is set apart.

Moreover, the push rod 14 is driven a distance b (<
The push rod 14 is set to advance by a), and the opening/closing door opening protrusions 15 provided on the push rod 14 are provided at equal intervals (a-b).

From this, the maximum number of feed holding chambers 1' that can be installed in the feed holding container 1 is a/b, where a/b.
If b=n (integer), (a-b)=(n-1)・
a/n, and a and (a-b) have a relationship between a regular scale and a vernier scale, that is, the principle of a vernier scale is applied.

Note that in this embodiment, the case where n=5 is used.

The drive circuit C is configured as shown in FIG. 9, and when the feeding time comes, the first timer _T1 causes the first timer switching contact _T1S to switch on the control circuit for the second timer _T2 for a certain period of time. Close, second timer
T ₂ is activated.

The operation of the second timer _T2 causes the interlocking
The timer switching contacts T ₂ S and T ₂ S' are switched to a position where the contact T ₂ S is open and the contact T ₂ S' is closed, and at this time, the switch piece 19' of the limit switch 19 is closed, The motor 16 is activated, which causes the drive protrusion 18 of the drive wheel 17 to
advances the push rod 14 by a distance b.

Further, since the drive protrusion 18 that has rotated once moves the limit switch 19, the switch piece 19'
is opened, and the associated switch piece 19'' is closed.

After that, the contact is closed due to the time-limited operation of timer _T2 .
By opening T ₂ S' and closing contact T ₂ S, the motor 16 is energized again.

As a result, the motor 16 rotates, and the drive protrusion 18
passes through the limit switch 19, the switch piece 19'' is opened and the switch piece 1
When 9' is closed, the motor 16 stops and the drive wheel 17 also stops rotating.

Then, when the energization time set by the first timer T elapses, the contact T ₁ S is opened, so the second timer
The control circuit for T ₂ opens and waits for the next feeding time. At this time, each contact and limit switch 19
The switch pieces 19', 19'' have returned to their initial positions as shown in FIG.

Since the automatic feeding device of the present invention is configured as described above, the motor 16 periodically rotates once by the drive circuit c controlled by the timer, and the drive protrusion 18 of the drive wheel 17 rotates with this rotation. Rack 20 is engaged to move push rod 14 a distance b.

By moving this push rod 14, the distance (a-b)
The opening/closing door opening protrusion 15 provided on the push rod 4 engages with the opening/closing door fixing hook 13 pivotally attached to the feed holding container 1 at a distance a, and the hook 13 is rotated to open the protruding engaging portion 12'. disengage with.

As a result, the opening/closing door 12 on the left side in the figure is opened in order, and the feed holding chamber 1' is opened at predetermined intervals.
The feed inside is fed to the domestic animals 6.

After all of the supplemented feed has been fed, the push rod 14 is pulled back manually or by reversing the motor 16, and the opening/closing door 12 is engaged with the hook 13 to close the door.

In this case, if another similar protrusion 15' is provided in front of the first opening/closing door opening protrusion 15 provided on the push rod 14 with an interval (a-b), the push rod 14 can be pulled back. You can continue automatic feeding without having to do this. Note that a plurality of these protrusions 15' may be provided at equal intervals (a-b).

As described above, the automatic door opening mechanism A using the principle of a vernier constitutes a simple drive unit having a simple structural principle, and enables regular automatic feeding with a small driving force.

The automatic opening/closing mechanism A can also be configured by an electrical mechanism using an electromagnet as the locking part and a device that generates an electrical signal to open the circuit of the electromagnet as the unlocking part.

As detailed above, according to the automatic feeding device of the present invention, the following effects and advantages can be obtained.

(1) The drive unit that opens the door can be significantly reduced and simplified, reducing its strength and driving force.

(2) Since the opening/closing doors can be sequentially opened using the vernier principle, the drive unit can be further downsized and simplified.

(3) The main resistance during driving is only the frictional force on the locking part of the opening/closing door due to the weight of one feed, and even heavy feed (raw grass for cattle, silage, etc.) Since there are only a few parts, automatic feeding can be easily performed with a relatively small driving force.

(4) Since the drive unit is simply constructed and the feed holding container is fixed, it is easy to install a cooling device, etc., and even feed that is easily spoiled or deteriorated can be automatically fed for a long time.
