ruling device. Figure 1 shows the scheme of an automatic feed dispenser; Fig. Dispenser control circuit. The automatic feed dispenser includes a drive 2 installed under the feeder 1 with a flap bottom 3 and an electromagnetic latch 4 installed on one of the arms of the rocker arm 5, the other arm of which has a feed dose metering sensor 6 and connected to the core 8 of the electromagnet 9 and winding through a hinge 7. 10, the sensor 11 of the position of the feeder 12, the load 13 of returning the flap bottom 3 to the initial position, the mechanism 14 of the partial reaction / performed in the form of a traction electromagnet 15 connected by means of a flexible rod 16 to the rocker arm 5 and interacting with a load 17, a power unit 18. the initial current setting resistor 19, the block contacts 20 and 21, controlled by the relay 22, pin 23, the switching device 24 connected through the amplifier 25, the decoder 26 and the trigger register 27 with the program device 28, the switching device 24 has several parallel circuits including resistors 29, connected via switching contacts 30, controlled by relays 31 to control buttons 32 for manually setting the feed of the feed and switch 33 for switching the operation mode to automatic or manual, in which winding 10 of electromagnet 9 is connected Through the block contact 20, contact 23 and the switching device 24 with the power source 18, and the initial current setting resistor 19 is connected in parallel with the switching device 24, made in the form of a binary-to-analog converter, to an analog signal of a stabilized direct current. The dispenser works as follows. According to the signal of the recognized animal, the software device 28, in accordance with a predetermined dose of food for the animal, gives signals to the nareley 31 of the switching device 24. At the same time, contacts 39 are closed in combination corresponding to the given dose of food. At the same time, the relay 22 triggers, as a result of its release, the block-contact 20 and through the included resistors 29 and the initial current setting resistor 19 across the winding 10 of the electromagnet 9 a current flows, under the action of which the measles 8 is held with a force greater than the weight of the feed by the value specified initial current with pbmoschiyu resistor 19 set the initial current. The blocking contact 21 closes the power supply circuit of the traction electromagnet 15, which, attracting the load 17, creates an oppositely directed force, which compensates for the action of the initial current, thus excluding the operation of the electromagnet 9 in the initial nonlinear part of the characteristic. When the weight of the feed in the storage unit 2 supplied by the feeder 1 is equal to a given dose, the measles B of the electromagnet 9 rises and the rocker 5 rotates at an angle sufficient to trigger the feed dose sensor 6, which turns off the feed supply to the storage unit 2 and using contact 25 turns off the electromagnet 9, de-energizing the winding 10. The signal from the sensor 11 of the position of the feeder 12 triggers the electromagnetic latch 4 and the folding bottom 3 of the drive 2 turns under the action of the weight of the feed at an angle sufficient to drop the feed into feeder 12. When the sensor 11 is activated, the position of the feeder 12 sets the trigger register 27 to the zero position. Relays 22 and 31 are de-energized by disconnecting power to the traction electromagnet 15 by the block contact 21. The interaction of the load 17 with the traction electromagnet 15 stops and the beam 5 and the measles 8 of the electromagnet 9 return to their original position. After dropping the feed, the flap bottom 3 of the accumulator 2 under the action of the load 13 returns to its original position (closes) and is connected to the beam 5 using an electromagnetic latch 4. The dosing and delivery of the feed to the next animal is similar to the above. In the event of malfunctions in the amplifier 25, decoder 26, trigger register 27, or software device 28, the operation switch 33 triggers and the dispenser adjusts to the average feed delivery rate that is the same for all animals. Thus, the dispenser provides improved metering accuracy and reliability. Claims 1.
