| The invention relates to a dosing technique and can be used for individually automated portion feeding of animals.

The purpose of the invention is to improve the efficiency of the dispenser by reducing feed losses during feeding and improving the accuracy of dosing.

Figo I shows the dispenser; Fig 2 shows a control system for the operation of the feed dispenser; on - a block diagram of the control of the metering unit with the interpretation of the structure of the program development block; FIG. 04 is an electrical circuit diagram of the load sensor of drive 0.

The automatic feed dispenser contains a vibrating feeder 1, a scale with a rocker 2 mounted on the prism 3 of the support post 4o. The left shoulder of the rocker arm is equipped with a storage unit 5c bottom 6 and an electromechanical latch 7 o

The right shoulder of the rocker arm is equipped with a counterweight in the form of a nut 8, which can be moved along the arm of the rocker arm within the specified limits, and the bar 9 with a foil-marked mark.

For discharging the weighed dose of feed, the dispenser is equipped with an inclined chute 10c.

The control system of the dispenser contains in series the animal recognition unit 11, the software device 12 and the software testing block 13.

The programmed number of pulses of the software device is processed by the program testing unit. The discharger discharges the electric actuator 15, releasing the bottom 6 of the accumulator 5, as a result, the feed dose is discharged into the feeding trough 30. After scooping the bottom, the bottom is closed and the rocker returns to its original position. The vibrating coil 28 of the feeder begins to work until the foil-tag of the strip 9 leaves the sensor gap 16. The feeder stops working.

At the output of the recognition unit, the number of the animal is generated in a binary-decimal code, which is fed to the address input of the software device,

As a software device

12, a permanent storage device (ROM) is used, for example, of the type K573RF20. The number of the animal is sent to the address input of the ROM from the recognition unit. According to this number, the information on the number of It is necessary to issue an animal with this number. This information enters the block 13 of the program,

The inputs of blocks 11 and 13, respectively, of recognition and testing of the program, are fed to information from the outputs of sensor 14 of the presence of an animal,

The figoZ shows part of the flowchart control block diagram with decoding the structure of the program development block 13. It contains the software device 12, the unloading electric drive 15, the accumulator loading sensor 16 and the vibrating feeder 17, the block

The program run, the program run consists of a low frequency generator 18, keys 19 and 20, an inverter 21, AND circuit 22, a stand-by multivibrator 23, an IS-NOT 24 circuit, a comparison circuit 25 and a counter 26 "

The unit functions as follows.

In the absence of an animal at the feeder, from the output of the software device 12 to the input of the circuit IS-NOT 24, all units arrive. At the input of the circuit IS-NOT, a zero signal is generated that locks the element AND 22, and the feed is not unloaded with any signal from the sensor 160 If the feed drive the portion of the sensor 16 is zero, which is inverted by the NOT circuit, the key 19 is opened, the low-frequency oscillations from the generator 1 are fed to the feeder solenoid 17, the feed enters the hopper. When the feed weight in the accumulator is equal to the preset, the state of the sensor 16 changes, at the output of the circuit a zero appears that locks the key 19, the process of loading the accumulator stops, however, the unloading of the accumulator does not occur, since the operation of the electric drive 15 unloads

When an animal appears at the feeder, information about the amount of coma that is required to be outputted to this animal comes from the output of the software device 12. At the output of the AND-HAY 24 circuit, a unit appears. This triggered zhivuschy multivibrator 23, which

The second impulse is fed to the counter 26, in which the batch is counted. After the accumulator is unloaded, the sensor 16 changes its state and the accumulator is loaded, which was described earlier0 The drive of the accumulator sensor 16 again changes its state, through the circuit AND 22, the waiting multivibrator 23 is started, and the next portion is unloaded. Subsequently, the operation cycle is repeated. The number of portions issued is taken into account by counter 26 and constantly compared by the comparison circuit 25 with the number specified from the software device 12. As soon as the number of portions issued equals the predetermined one, the output of the comparison circuit 25 forms a zero. 20 operation of the electric drive 5 unloading ,,

If in the process of giving out food the animal leaves the feeding trough, the delivery of food will not occur, because the delivery signal will be blocked from the program device through the AND-24 element 24

Unit 13 of working out the program with its outputs is connected with sensor 14 of the presence of an animal,. Once the load of the ca-dose of feed from accumulator 5 is carried out by opening the bottom 6 with the help of an electromechanical latch 7 under the action of an electric unloading actuator 15, controlled by a 15-hour drive 16

Sensor 16 — commercially available sensor. The principal electrical circuit of the sensor is shown in FIG. 40. A sinusoidal oscillator is assembled on transistor VI. If there is no metal plate between coils L1 and L3, oscillations generated in circuit L1C3 are induced in coil L3 and rectified by a diode V20 Open-25C transistors V3 and V4, close transistors V5 and V7. At the output of the sensor, the signal is one. When a metal plate hits between the coils L1 and L3 of a metal plate, the connection between them breaks and the V3 coil does not oscillate V4 is closed, and transistors V4 and V7 are opened. At the output of the sensor, the signal is zero

Structurally, the sensor is designed in such a way that between the coils L1 and L3 there is a slot in which the plate can move,

As a sensor 14 40, for example, a reed switch can be used, which

It works by interacting with a magnet located on the collar of an animal.

The feed dispenser also contains a vibrating coil 28 of the feeder and a counterweight to the 29 of storage 5, the feed dose is discharged into the feeder 300

The dispenser works as follows

When an animal moves through the recognition unit 11, its number is read with a signal transmitted to the software device 12, which is recorded for each animal. The programmed number of pulses or dosing cycles is detected by the program development unit 13. when the sensor 14 is activated, the electric actuator 15 unloads the dispenser, triggers the bottom 6 of the accumulator 5 from the electromechanical latch 7 V As a result, the pre-weighed feed dose or feed remaining to the previous animals that were not eaten is discharged along the slope chute 10 into the feeder 300. The 2 weight mechanism returns to its original position under the action of the counterweight 8, and the foil mark of the bar 9, which was left unloaded on d sensor 16, lowering the sensor, enters the sensor gap and causes the appearance of a logical unit, which characterizes the beginning

When the weight of the loaded feed reaches equality with the weight of the counterweight 8, the beam starts to take a horizontal position. Planck 9, pivotally connected to the rocker, begins to lift, and when the foil tag leaves the sensor 16, the feeder stops working. inclined towards the feeder to the inclined chute 10, and at the end of the pause, the electric drive 15 is unloaded - the dispenser is discharged. The number of dosing cycles depends on the preset program. The single cycle does not end with the actuation of the electric drive 15 unloading the dispenser. When the next animal passes through the recognition unit, the cycle of issuing the first batch and further working out the program repeats
