Description

The invention relates to amateur fish farming, and in particular to devices for automatically feeding fish for a long time.

A device for distributing feed to fish in an aquarium is known, including a float mounted on an axis rotatably with a feed accommodation device, the device being provided with a fixed gear sector, on which a leash is rotatably mounted, and a gear wheel for engaging with a gear sector placed on the same axis with the float and rigidly connected with it. The free end of the leash is attached to the axis to rotate it together with the gear when the water level in the aquarium / cm changes. patent of the Russian Federation No. 2038012, cl. A 01 K 61/02, 1992 /.

There is also known a device for distributing food to fish in an aquarium, including a hinge mounted at one end on a fixed axis, a device for placing food and a float that monitors the decrease in water in the aquarium, while the device for placing food is made in the form of a fixed bin in the cavity of which the axis of the rotary feeder for feed, while the device is equipped with a flexible link, one end of which is connected with the free end of the leash, and the second is wound on the axis of the rotary feeder, The wok is placed on a leash with the ability to move along the length of the last / cm. application of the Russian Federation No. 96105440, cl. A 01 K 61/02, 1996 /.

The specified device is the closest to the proposed and is adopted as a prototype.

The disadvantage of the prototype / as well as the analogue / is the dependence of the rate of feed delivery on the rate of decrease in water level in the aquarium, and the rate of decrease in water level depends on many factors, for example, the ambient temperature, the area of the water mirror in the aquarium, etc. This does not allow for constant device performance. In addition, the feed in the prototype is issued constantly.

The technical result of the invention is the creation of a device with constant indicators for the issuance of feed and with the possibility of changing this indicator, for example, on the number of fish in the aquarium.

The technical result is achieved by the fact that in the device for feeding fish to the fish in the aquarium, which includes a drive, a feed hopper and a feeder with a drive shaft located at the bottom of the hopper, according to the invention, the drive is made in the form of a clock mechanism, the output link of which is connected to the feeder shaft.

In addition, the output link of the clockwork is made in the form of a disk with one or a group of lugs placed on the disk with the possibility of periodic engagement with a lance sprocket mounted on the drive shaft of the feeder.

In addition, the device feeder is made screw.

In addition, the lugs on the drive disk are removable.

The invention is illustrated by drawings, which depict:

figure 1 is a General view of the proposed device for the issuance of feed to fish in the aquarium;

figure 2 - section aa in figure 1, the mounting unit of the device on the aquarium.

The device for distributing food to fish in the aquarium includes a drive 1 in the form of a clock mechanism, the output link - the hour hand is made in the form of a disk 2 with one or a group of tines 3 fixed on it.

The watch case is attached to the bracket 4, to which, in turn, is attached a hopper 5 for filling feed 6 into it. At the bottom of the hopper there is a pipe 7 for accommodating a screw feeder 8 in it with a drive shaft 9.

A sprocket sprocket 10 is fixed to the drive shaft, interacting with its teeth with the spindles 3.

The bracket 4 is made with a gripper 11 mounted on the wall 12 of the aquarium and having a screw clamp 13.

A device for distributing food to fish in an aquarium works as follows.

When the disk 2 is rotated by a clock mechanism 1, the pin 3 enters between the teeth of the sprocket 10 and rotates the latter by a certain angle. The value of this angle through the shaft 9 rotates the screw feeder 8, capturing feed 6 from the hopper 5 and pouring it into the aquarium.

Increasing the number of consecutive tars (which are attached with the device), increase the angle of rotation of the feeder, and therefore the amount of feed delivered to the aquarium.

The clock mechanism has the simplest design and is calculated on the rotational speed of the disk 2, equal to one revolution in 12, 24 or 36 hours. Since the effort in the parts of the device is measured in grams, many parts can be made of low cost plastic.

The clock mechanism can have a mechanical / spring / drive or electronic-mechanical with battery power.

Claims (1)

A device for distributing feed to fish, mainly in an aquarium, including a drive in the form of a clock mechanism with an output link, made in the form of a disk, a feed distribution mechanism and a hopper for the latter, characterized in that the feed distribution mechanism is designed as installed under the hopper and placed in the nozzle a screw having an asterisk fixed on its drive shaft, while a sprocket is mounted on the disk with the ability to interact with the asterisk of the auger drive shaft, sockets for installing additional evok, and the device is equipped with a set of lobes by the number of sockets in the disk.
