Description

[Detailed description of the device]

[Field of Industrial Application] [0001] The present invention relates to a feeding device for ornamental fish bred in an aquarium or the like.

[Prior Art] A conventional automatic feeding device for animals uses a sensor, a transistor, a timer, a relay, etc. to drive and control a motor (for example, Japanese Examined Patent Publication 52-14190, Japanese Examined Patent Publication 62-16614, Japanese Patent Publication No. 2-4267, Japanese Patent Application Laid-Open No. 2-242630, Japanese Patent Application Laid-Open No. 4-104745), or a mechanical or manual feeding device which does not use a motor (for example, Japanese Patent Publication No. 58-20569, Japanese Patent Application Laid-Open No. 2-206969). -150224). It is enough to feed the ornamental fish a few times a day, enough to feed it once, but it does not pose a problem even if you give it a little. For feeding ornamental fish, it is sufficient to drive a small motor for tens of seconds to a few minutes a day. However, in order to control this motor, sensors, transistors, timers, relays, etc. must be used, and some kind of current must be kept flowing for a long time, resulting in a waste of energy. The equipment may be complicated and may require a household AC power supply.

[Problems to be Solved by the Invention] When a person is away from home during a trip or the like, an ornamental fish may be killed. Also, if you ask someone to feed you while you are away, the water may have spoiled due to overfeeding. There has been a demand for an inexpensive and simple automatic feeding device that can continue feeding the ornamental fish even during a long absence. The mechanism of the conventional device was complicated. The most desirable automatic feeding device for ornamental fish is one that has a simple structure, is easy to operate, is small and lightweight, and has a low manufacturing cost.

[Means for Solving the Problems] When observing a goldfish in an aquarium, it is often seen that a pebble at the bottom of the water is put into the mouth and spit out when there is no food. This proposal was devised by taking advantage of the habit of ornamental fish in order to eliminate the drawback that the conventional automatic feeding system for ornamental fish has a complicated mechanism and the production cost is high. This can be explained with reference to the figure. (A) The on / off control of the switch (4) is controlled by the combination of the switch-controlled rotating wheel (7) having a recess on the outer periphery, the switch control rod (5) and the switch lever (3). Mechanism B. A bait supply consisting of a bait container (11) with a bait drop hole (12) and a bait transport wheel (10) with a recess on the outer periphery to carry bait dropped from it. Mechanism C Switch control wheel (7) and bait transport wheel (10) are linked by an axle (15) and hung by a mechanism switch lever (3) driven by a motor (8) and a gear (9). The drawstring (2) with the ball (1) is constructed as described above, and instead of the conventional automatic feeding device that electrically or mechanically controls the motor using a clock or the like, , To the ornamental fish itself By starting the motor, the device is simplified.

[Operation and Example] A ball (1) simulating a pebble or a bait is tied to a thread, which is hung on a switch lever (3). When the ornamental fish puts the ball (1) in its mouth and the switch lever (3) is pulled for a moment, the switch (4) is closed and the rotation of the motor (8) is transmitted to the switch-controlled rotating wheel (7). As a result, the upper end of the switch control rod (5), which controls the on / off of the switch (4), moves from the recess of the switch control rotary wheel (7) to the flat part, and the switch control rod (5) is pushed down, and the switch (5) is pushed. 4) is turned on. When this happens, the switch-controlled rotary wheel (7) continues to rotate, but when the switch control rod (5) comes into the recess of the switch-controlled rotary wheel (7), the switch lever (5) is actuated by the spring built in the switch lever (5). 3) is flipped up and the motor (8) stops rotating. During this time, the bait transport wheel (10) connected by the axle (15) also rotates, and the bait that has fallen from the bait drop hole (12) of the bait container (11) is received and transported by the recess (18) of the bait transport car tire. To do. The bait transport wheel (10) is installed directly below the bait drop hole (12) of the bait container (11) and has recesses. The feed amount is adjusted by the number and size of the recesses. be able to. Therefore, some spares of easily replaceable bait truck tires (16) with different numbers and sizes of recesses are prepared. The switch-controlled rotating wheel (7) controls the rotation of the motor (8) by turning on and off the switch (4) by the flat portion and the concave portion. The reactivity when the switch (4) receives an input is determined by the rotation speed of the switch-controlled rotating wheel (7) and the size of the concave portion (length along the outer peripheral direction). That is, in order to feed the ornamental fish in response to one action of pulling the switch lever, the rotation speed of the switch control rotary wheel (7) is increased and the length along the outer circumference of the recess is shortened. To avoid overfeeding the ornamental fish, feed it only after several switch lever pulls. For that purpose, the rotation speed of the switch-controlled rotary wheel (7) should be slow and the length of the concave portion should be long. Prepare some spare tires for the switch-controlled wheel (7) and replace them as appropriate. The slower the rotation speed of the switch-controlled rotating wheel (7), that is, the larger the reduction ratio of the gear (9), the easier the on / off control of the switch. Care should be taken for the bait container so that the load applied to the bait transport car (10) does not fluctuate significantly depending on the amount of bait in the container. If it is installed with an inclination or it is made vertical, its main part should be installed at a position displaced from the feed transport car (10) so that the weight of the feed does not directly impinge on the food transport car (10). As a result, a large amount of food can be processed even with a small motor, and long-term continuous feeding is possible.

[Effect of the Invention] It is possible to keep feeding the ornamental fish while keeping the water clean even during a long absence. Moreover, the device has a simple mechanism, is easy to handle, and does not require a household AC power supply, so it can be used outdoors easily.
