(ri4) DEVICE FOR LV TOLA ATI не a certain FACI 103-4 NAVDEG ANIMALS NODES

The invention relates to the mechanization and electrification of the processes in animal husbandry and can be used for the automatic distribution of feed in milking plants, as well as in the automatic control system. The known device for automatic recognition of the animal number, containing a tag with a hodded HOMepoivi hung on a collar, is used on farms with a psgolovy herd up to .100 cows. In order to increase operational reliability and simplify the design of the device, it is proposed. The device is equipped with an electromagnet for capturing the tag mounted under the feeder and a camera with sensors transmitting a signal corresponding to the animal number to the reading mechanism. FIG. 1 shows the proposed device, side view; in fig. 2 - camera with sensor KavK; in fig. 3 - tag in two projections; in fig. 4 - Shane fishing. The device includes an electromagnet 1 located under the trough, made in the form of a stator of a flat electric motor. Magnetic wire msh-nit is made of electrical steel sheets. In the grooves wo, there is a threex (|) az on. winding 2 so that a running magnetic field, which ensures the tag's capture from the surrounding space and its orientation, is present above the stator surface. The gripping sector is guided by the guiding flaps 3. The tag moves along the stator) and the eloctromagnet into the chamber 4 is in the best way ocyi BCTB- is in a non-uniform magnetic field created by the non-magnetic material plane and the movement at an angle of 5 to the surface of the stator. The camera (see Fig. 2) consists of two pro- congents, the boxes 6 are located opposite, the KOTVijs are attached to the guide plane at the distance of the tag width. Sensors 7 are placed in each of the crust, which are represented by a coil with a mshm-gitk core. . The sensor rods are perpendicular to the middle of the side of the coil 8.

An adjusting steel screw 9 is installed against each sensor.

The maximum number of sensors in the camera, for example, when reading serial numbers / o 6; ipKB from 1 to 1024, written in binary; system is 10 pieces, up to 2048 11 pieces, etc.

The tag (see Fig. 3) consists of an iron plate 10, to which an aluminum is attached | «| niev box 11. On the sides, the co-I are timidly fixed from 12 of the non-magnetic. material. The number and mutual sonnet-strips encode the serial number of the dog. 15

Shanela is a bundle of hydrastavla (see fig. 4) belt 13, which is attached to the neck of the animal. Its ends are enclosed by a metal clip-14 and fastened with a bolt 15Г. A half-ring 16 is inserted into the hole of the metal-2 clamp and the tag 18 is suspended by the flexible flat belt 17; the length of the bend belt 17 is constant for all animals; 25

The mode of operation of the vehicle for animal number recognition is short-term and is implemented as follows.

When an animal enters the milking machine, an electromagnet is turned on. The tag is attracted to the guide plane, is oriented along the stator and moves into the chamber. Sensors transmit to the mechanism of reading; signal on the presence of a tag in the camera and sig-i in: On the i Niger in accordance with the location of the strips of magnetic material on the croftaaax. tags. At the signal of the code (the reading mechanism deciphers the number of the cow that entered the milking sta-i nok and connects the animal to the milking and feeding automated control system.

Formulas a and goiter

The device for automatic recognition of the animal number, containing a tag with a coded number, placed on the collar, a readout mechanism and a feeding trough, which is due to the fact that, with an increase in reliability and simplification of the design, an electromagnet for trapping the tag is installed under the gas a feeder, and a camera with sensors, which cause a signal corresponding to the number of stomachs on the reading mechanism. x // COUNT / x;
