Description

one

This invention relates to an agricultural technique and can be used for automatic portion feeding of animals.

A device is known for determining the amount of feed in accordance with the identifiable number of the animal represented by a sensor comprising coding generators. The known device determines the amount of feed to be discharged as follows 1.

When an animal enters the premises, it is recognized by the code combination of the coding generators of the sensor embedded in its collar and given a certain amount of feed.

However, the known device does not allow a portion of the specified amount of feed to be given out, which leads to its loss of m.

The purpose of the invention is to automate the task of servings of feed and reduce its loss.

The goal is achieved by the fact that detectors, keys, a counter, a decoder, a switch, a trigger, an AND element are introduced into the proposed device, and the output of the first circuit is connected through the first detector to the input of the first key, the output of which is connected to the input of the element I, the output of which is connected to the input of the generator, and the second output of the first key is connected to the input of the counter, the outputs of which through the decoder are connected to the input of the switch, the output of which is connected through a trigger to the second input of the element And, the output of the second

contour through the second detector is connected to the input of the second key, the output of which is connected to the inputs of the initial installation of the counter and trigger.

The drawing shows a block diagram

the proposed device. It consists of a tuned circuit 1, a detector 2, a counter 3, a decoder 4, a switch 5, a key 6, a trigger U, a tuned circuit 8, element I 9, a detector 10, a generator

11, the key 12.

The sensor for automatic portion feeding of animals works as follows. Before feeding the animal, the switch 5 is installed in a positioi, which determines the number of servings, set in accordance with the amount of feed for the individual diet.

When an animal passes by a generator that generates a radio signal with a frequency of / 1, then with the arrival of this signal on the tuned loop of its output through the detector 10 to the input of key 12, the output of key 12 receives a signal to install the memory elements of counter 3 and trigger 7

state of logic 0. In the state of logic O s

of the outputs of counter 3, the code combination corresponding to the zeroed number of feeds delivered, and the output of trigger 7 to the first input of the eletant and AND a "enable" signal is issued, which determines whether single signals from the output of the key 6 are received through AND 9 to the input of the generator 11 for start and generate sigchala frequency / s. in which the dispenser is triggered and the animal feeds a portion of the feed.

When an animal approaches a feeder with a generator that generates a radio signal with a frequency of / 2, this signal enters configured circuit 1 and passes through detector 2 to key 6 input. Then, from the first key 6 output, a single signal is output, which enters the counter 3, recorded as portions of food given to the animal. From the second output of the key 6, a single signal arrives, through element 9, to the input of the generator 11, to start it. Then a radio signal with a frequency fs will be output from the generator 11 output, which is converted into a single signal in the feeder receiver and starts the feed portion dispenser. The animal is thus given one portion of feed to the feeder. Thereafter, the generation of the radio signal with a frequency of / 2 is stopped, and therefore the next portion of the animal is not given until the portion of feed that has been previously released is eaten.

If the animal has eaten a portion of food in the feeder, then a radio signal with a frequency of / 2 will be generated, which, as in the previous case, having entered the tuned circuit 1 and passing detector 2 and key 6 in the vtsde single signal, will go to the input of counter 3, recording the output The next batch of feed, c, will go through element 9, to the input of generator 11, determine its start and transmit the radio signal with frequency / 3, which, after its conversion, in the receiver of the feeder, the portion dispenser is triggered, delivering the next batch of feed to the feeder.

If the cord is given to the animal last in the feed between the portions assigned to it, then in the counter 3, when writing the last portion, the state of the binary bits will determine the binary code combination of the specified number of portions of the feed. Then,

Post-sampling from the outputs of the counter 3 of this binary combination to the inputs of the decoder 4, it is decrypted and from its output, which size is determined by the number of predetermined portions, produces a single signal. Since this output of the downloader 4, in accordance with the installation of the switch 5, is connected to the input of the trigger 7, the trigger 7 also changes its state from its output

the input element And 9 receives a signal "prohibition. This signal prohibits the entry of single signals obtained by conversion in the detector 2 and the key 6 radio signals with a frequency of / 2. Therefore, the jynotny after the last portion of food eaten while it is at the trough will not give out an extra portion of food.

In order to carry out a repeated feeding cycle, the animal must again go through

past the generator that generates a radio signal with a frequency of / 1, in order to write off in the counter 3 the recorded number of portions of food given to the animal earlier, and set trigger 7 to logic 0.
