Description

The invention relates to agriculture, to the field of livestock, and can be used on livestock farms to divide the herd of animals into groups depending on the state of health.

The aim of the invention is to improve the accuracy and performance of the device, allowing to divide the animal herds into healthy and with deviations by assessing their state according to the degree of tension of the regulatory mechanisms of organisms, the determination of biological signs (pregnancy, hunting, and others).

The drawing shows a block diagram of a device for dividing a herd of animals into groups for health reasons.

The device for dividing the herd of animals into groups for health reasons contains three opening gates 1, 2, 3 for exiting and one gate 4 for entering animals, equipped with actuators 5, 6, 7, 8, positioning blocks 9,10,11 and block 12 determining the location of the animal, which are connected respectively to the four outputs and inputs of the control unit 12, an identifier consisting of a sensor 14 on the collar connected via an electromagnetic field with antennas 15 connected to the animal number recognition unit 16, memory unit 17, diagn the rest of the platform 18 for determining animals by groups, platforms 19, 20, 21 for dividing into groups of animals, cattle drive 22, sensors 23, 24 of the electrocardiogram and thermal field, mounted on the moving part of the system 25 for fixing animals in a given position, a logical block 26, the first input of which is connected to the first output of the animal number recognition unit 16, the second input - to the output of the cardiac amplification unit 27. and the third input 5 to the output of the signal amplification unit 28 of the thermal field sensor, the deviation unit 29, which is connected via the bus to the memory unit 17 and the output '' is connected to the input of the control unit 13. 10, the fifth output of which is connected to the first input of the electromagnetic valve block 30. new, which serves to supply compressed air to the animal fixation system 25, while the outlet pipe of the electric pump 32 is connected to the 3Q unit through a receiver 31, the device also includes a timer 33.

The control unit 13, the memory unit 17, the logical unit 26, the deviation unit 29 are made at the level of known functions.

The device operates as follows.

An animal from cattle drive 22 with an open entrance gate 4 and a closed output gate 25 !, 2,3 enters diagnostic platform 18 for distributing animals into groups.

After the animal passes through the entrance gate 4, the unit 12 for determining the location of the animal is triggered, the signal from which is sent to the control unit 13, issuing a command to the actuator 8 to close the entrance gate 4. At the same time, the control unit 13 provides a signal 35 to the solenoid valve unit 30, which open access of compressed air to the pneumatic system 25 of fixing the animal in a predetermined position. In this case, the sensors 23 and 24, respectively, of the electrocardi5 of the signal and the thermal field are pressed to the corresponding places of the animal's body.

After receiving confirmation signals about closing the entrance gate 4 and fixing the animal, the identifier, consisting of a sensor 14 with the encoded number of the animal, two antennas 15 and the recognition unit 16, recognizes the number of the animal and starts the timer 33 on the second output of the recognition unit 16, which turns on the second output 28 amplification of signals from the sensor 24 of the thermal field. The amplified signal enters the logic block 26, in which the current values of the parameters of the thermal field are determined. The current values of the parameters of the thermal field are compared with the deviations set in block 29, while the set values are read in the memory block by the recognized animal number.

If there are deviations in the parameters of the thermal field, then the signal from the control unit 13 is fed to the actuator 7, which opens the output gate 3 for the animal to enter the animal care area 21.

The signal from the first output of the timer 33 turns on the block 27 amplification of the signal of the sensor 23 of the cardiac signal. The amplified signal is fed to the logic unit 26, in which the current values of the parameters of the cardiac signal are determined. The current values of the parameters of the cardiac signal are compared in the block 29 deviations with the set, which are read by the recognized number in the block 17 of the memory. If there are deviations in the parameters of the electrocardiogram, then the signal from the control unit 13 is fed to the actuator 5, which opens the gate 1 for passage of the animal to the platform 19 for self-service.

If there are no deviations in the parameters of the cardiac signal and the thermal field, then the control unit 13 gives a command to the actuator 6 to open the gate 2 and the animal passes to the platform 20 for healthy individuals.

After the animal has passed through one of the exit gates 1,2, 3, the corresponding positioning blocks 9,10, 11 are triggered and the control unit 13 issues a command to the actuators 5. 6, 7.8 to close the corresponding exit gates 1, 2, 3 and open the entrance gate 4 .

In the future, the cycle of the device is repeated.

The device for the separation of animals for health reasons provides an earlier and objective determination of deviations in the state of animal health and thereby reduces the loss of the resulting product.

The use of only one identification and diagnostic unit in the device simplifies the device, reduces the cost of materials and labor costs in its manufacture.
