2. The device according to claim 1, wherein the program unit is made in the form of a micromotor that is kinematically connected through a coupling to a shaft on which the first and second disks are fixed with grooves along the peripheral surface in which the disks are installed perpendicularly plates with reflective surfaces and transverse grooves on the outside, with the plates

secured with locking rings, in the lower part of the program node an additional light source is mounted with the slings and the first and second blocks of photoresistors optically connected through the arcing surfaces of the plates with the additional light source and electrically connected to the inputs of the control unit; .

The invention relates to agriculture, in particular to the batch preparation of feed on livestock farms.

A feeding device is known, including a feed dispenser. with Mobile feeders and Dbzer, consisting of a hopper, a feeder with a drive disk and an nporpaNBwiHoro device in the form of a pack of plates made of elastic material installed on the side walls of the mobile feeders.

When kopMyiaeK is moving, the plate packs interact with the drive disk of the feeder, and the feed from the hopper I enters the feeder. The change in the rate of discharge is made by adjusting the length of the working, part of the package by unscrewing the appropriate number of plates on the rod of the Cl7 bag. The disadvantages of this device are the high complexity of setting up the dosing program and the low reliability.

The closest to the present invention is a program-controlled feeding device containing a screw-driven feeder, with movable feeders on an infinite C 2 chain located under the discharge window.

However, this device is characterized by low reliability in operation.

The purpose of the invention is to increase the reliability of the device in operation.

The goal is achieved by the fact that the feeding device with programmed control is equipped with a software node, a command unit, a control unit and a discrete one, and movable feeders - with Yignal flags mounted on an infinite chain against each movable root, the command unit being in the form of a light source, photoresistor fixed on the base with a gap between them with the possibility of passing in it the signal flags of the mobile feeders /

the first output of the control unit is connected to the first input of the diffuser, the second input of which is connected to the photoresistor of the comand block, the other outputs of the control unit are connected to the metering drive.

The software is made in the form of a micromotor, which is kinematically connected through a sleeve to the shaft, on which the first and second disks are fixed. With grooves on the peripheral surface, in which plates with reflective surfaces and transverse, nyish grooves on the outer side are installed, and the plates are fixed with locking rings, and in the lower part of the program node there is an additional light source with lenses and the first and second blocks of photoresistors, optically connected through reflective surfaces and plates with an additional light source and electrically connected to the inputs of the control unit, the output of the same discrete1 is electrically connected to the micromotor; iporpaMMHoro node.,

FIG. 1 shows the device, a general view; in fig. 2 - software node, section / in FIG. 3 is a plate with reflective surfaces; FIG. 4 - block diagram of the software node

The device contains a screw dose of Ifop 1 with a drive 2, under the discharge window 3 of which there are movable feeders 4 on the endless chain 5 and is equipped with a software node b, a command block 7, a control unit 8 and a discrete 9, a-movable feeders 4 signal flags 10, mounted on an endless chain 5 opposite each moving trough 4, the command block 7 being designed as a light source 11, a photoresist 12 mounted on the base 13 with a gap between them with the possibility of passing the signal flags 10 of the moving trough in it 4, the first control unit 8 is connected to the first input diskretora 9, a second input coupled to the command block 12 frtorezistorom 7, the other outputs of the control unit 8 is connected to the actuator 2 of the dispenser 1.'s Program. The mountable unit 6 is made in the form of a micromotor 14, which, through the sleeve 15, is kinematically connected with the shaft 16, on which the first and second disks 17 and 18 are fixed with grooves 19 on a peripheral surface, in which plates 20 are perpendicular to the disks 17 and 18. with reflective surfaces 21 and transverse grooves 22 on the outer side, the plates 20 are fixed with locking rings 23, and an additional light source 24 with lenses 25 and the first and second blocks of photoresistors 26 and 27 is optically mounted hd resizing surfaces 2 with an additional light source 24 and electrically connected to the inputs of the control unit 8, the output of the sampler -9 is electrically connected to the micromotor 14 of the program node 6. The digitizer 9 includes an indicator made in the form of a relay with opening contacts and a delay mechanism, consisting of a relay and a capacitor The control unit 8 consists of a gain unit, a reference unit, a speed selection unit and a drive control. The device works as follows.

F & g When the mobile feeder 4 approaches under the discharge window 3 of the dispenser 1, the signal flag 10 overlaps the light beam from the light source 11 to the photoresistor 12 command block 7. The resulting signal of the photoresistor 12 passes through the discrete 9 to the program node b, which turns on the micromotor 14 to turn the disk 17 on one step. The signal from the additional light source 24 through the lens 25 hits the reflector surface. 21 plates 20 and further to the corresponding photo-cutter of the photoresistor 26, from where the signal goes to the control unit 8, where each photoresistor has its own time relay channel with a certain setpoint. From the control unit 8, a signal is sent to the discrete 9 to open;) the micromotor 14 and the command to turn on the actuator 2 of the dispenser 1. After the installation time of the time relay has expired, the actuator 2 is turned off. At the approach of the next mobile feeder, the 4 steps of the operation of the device is repeated. After the disk 17 has completely rotated, the disk 18 with the photoresistors block 27 is put into operation. The operation time of the dispenser 1 above the moving trough 4 determines the required dose. The invention allows to increase the reliability of the device, due to a simpler design, which has a significant economic effect.
