The invention relates to dosing techniques in agriculture and can be used for individual automatic batch feeding of dairy cows outside the milking parlor.

The purpose of the invention is to improve the metering accuracy for mixed fractions feeds by phased loading and the use of a dampening system.

To achieve this goal, loading the balance takes place in two stages. At the first stage of dosing, the vibrator feeder operates at a frequency (p, which ensures its maximum performance. In this operating mode, the scales are subjected to maximum dynamic loads, which lead to large errors. To dampen these loads, an additional damper is installed to ensure their damping. At a frequency 1 part of the feed is loaded, equal to approximately 90% of the dose per 100 g. Then, the vibrator feeder is automatically switched to the frequency (pi, which ensures maximum accuracy five dosing. Download speed thus decreases the dynamic loads are reduced and that are quenched and also via damper that reduces the error. The total batch time is also reduced with the contraction due to the load time of the first stage dosing.

The automatic feed dispenser contains a vibrating feeder 1, rigidly connected to a vibrating coil 17 mounted between the storage hopper and the balance, the balance with the beam 2 resting on the swinging prisms 3 of the support column 4, which are pivotally attached to one arm: a one-piece drive 5 with a folding the bottom 6, swinging on the axis and a mechanical latch 7 attached to the wall of the drive 5, facing the feeder, as well as the stock of the damper 8. and to the other

10 with a foil label with a counter-. som 14 at one end and an adjustable stop stop 15 at the other, freely moving in the sensor 12 and connected to the arm of the rocker arm by means of an adjustable stop stop. The discharge electromagnet is attached to the base of the feeder so that, when activated, the core of the electromagnet opens the latch 7, the inclined chute 10 for moving the feed from the accumulator 5 to the feeder 16, located between the drive and the feeder. The control system includes a unit for recognizing the number of a live animal 11, the input of which is connected to the output of the animal presence sensor 21, and the output to the input of the software device 19, for setting the amount of feed to be fed, the output of which is connected to one of the inputs

5, a read-only memory device, for example of type K573RF2, is used as a software device 19.

An animal number is received at the address input of the ROM from the recognition unit. According to this number, information on the amount of feed that needs to be fed out is preliminarily written to this cell from the corresponding memory cell of the ROM at the information input

5 animals with this number. This information enters the block 20 of the program. Information from the outputs of the animal presence sensor 21 is supplied to the inputs of blocks 18 and 19, respectively, of recognition and execution of the program.

In FIG. 5 shows the electrical circuit of the sensor 12 and 13 of the storage device, the sensor type FOOD - commercially available sensor. A transistor V1 has a sinusoidal oscillator. If there is no metal plate between the coils L1 and L2, the oscillations created in the circuit L103 are induced in the coil L3 and rectified by the diode V2. Transistors V3 and V4 open, and transistors V5 and V7 close. At the output of the sensor, the signal is unity. If there is a metal plate between the coils V1 and V3, the connection between them is broken, and no oscillations are induced in the coil L3. Transistors V3 and V4 are closed, and transistors V4 and V7 are opened. At the output of the sensor, the signal is zero. Structurally, the sensor is designed so that between the coils VI and V3 there is a slot in which the plate can move.

As the sensor 21 can be used, for example, a hermetic window, which is triggered by interaction with a magnet located on the collar of the animal .; : .. In a cylindrical body 1 filled with liquid 2, the rod 3 moves in the guide cover 4. At one end of the rod there is a piston 5 with capillary holes 6. At the other end of the rod and the lower end of the body are fixed earrings 7 and 8 for fastening, respectively to the rocker arm and to the base of the weight mechanism.

The dispenser works as follows. When the animal moves through recognition unit 18, its number is read with a signal transmitted to software device 19, in which the feed rate for each animal is recorded. The programmed number of pulses or dosing cycles is processed by the program execution unit 20. The monitoring of the development of the program is automatically carried out by the sensor 21 of the presence of the animal at the feeder. Simultaneously with the actuation of the presence sensor 21, the dispenser unloading actuator 22 is activated (Fig. 1), releasing the bottom 6 of the accumulator 5 from the electromechanical latch 7. As a result, the pre-weighed dose of feed, or left with the previous animal not eaten, is discharged along the inclined chute 17 into the feeder 16. After feeding the feed, the electric drive 22 is de-energized, the bottom of the drive returns to its original position and is fixed by an electromechanical latch 7 due to the inertial force of the counterweight 24. After unloading the drive The balance arm 2 of the weighing mechanism with the help of the damper 8 smoothly returns to its original position under the action of the counterweight 9, and the foil marks of the slats Yui.11, which were unloaded above the sensor 12 and 13, respectively, lowering the fit, enter the gaps of the sensors, with an additional counterweight 14 mounted on the lower end of the bar 10 is lowered to touch with the base of the weight mechanism. The return of the weighing mechanism to its initial position causes the appearance of a logical unit at the output of the sensor 13, which characterizes the beginning of the operation of the vibrating coil 23 of the feeder at the maximum production frequency f |. The damper 8 dampens the dynamic impact of large feed particles and protects the balance from sudden dynamic vibrations. When the weight of the loaded feed reaches an equal weight with the weight of the counterweight 9, the rocker will begin to occupy a horizontal position as far as it will go into the limiter 15 of the bar 10, which was in a resting state when it was being measured at the maximum production frequency. In this position, the beam will be held by the limiter 15 and the counterweight 14 of the bar 10. The bar 11, pivotally connected to the beam, rises, and at the moment the foil mark leaves the sensor 13 (coincides with the moment the beam rests on the limiter 15), switching to low-frequency frequency f2 .

The first loading stage is completed, with 90% of the feed dose weight loaded into the drive. When, when the feeder is operated at a low production frequency fe, the weight of the feed loaded is equal to the weight of the counterweight 14, the beam will begin to tilt towards the gutter. In this case, the bar 10, together with the counterweight 14, coupled to the beam, begins to rise and, at the moment the foil mark leaves the sensor 12, the operation of the feeder is stopped. The beam tilts towards the feeder towards the inclined trough 17 and at the end of the pause, the unloading electric drive 22 is turned on and the dispenser is unloaded.

The number of dosing cycles depends on the Preset program. Moreover, the last

the cycle does not end with the actuation of the dispenser discharge electric drive 22. When the next animal passes through the recognition unit, the feed dispensing cycle of the first portion and the further development of the program is repeated.

Reducing the dosing portion to a discrete value of 100 grams, which, when weighed by the dispenser n times, will make up the portion for any animal depending on the milk yield.

The proposed automatic feed dispenser was manufactured and tested as part of an automated station for managing and recording feeding modes of concentrated feed to cows outside the milking parlor. The portion weighed by the dispenser was taken equal to 100 g. The operating frequencies of the vibrator feeder were equal: fi 20 Hz, fa 14 Hz. As a result of laboratory tests, it was found that the dosage error with the proposed dispenser does not exceed ± 1.5% (the laboratory test report is given in the appendix).
