FIG L

The invention relates to agriculture, industrial livestock.

The aim of the invention is to improve the accuracy of controlling the loading of the working body of the feeder.

J - timing diagrams of the operation of frequency filter elements; Fig 4 is a generalized filter circuit diagram; Fig. 5 is a generalized block diagram of an adder.

The device for feeding the animal includes a receiving funnel 1, a feeder with a working body 25 placed therein mechanically connected to the drive 3, equipped with a speed controller 4, which is connected to the output of the adder 5S connected to the outputs of the setters of the NORM for feeding out the feed 6, the number of animals 7 , the feeding front 8, the capacity of the feeder 9, the feed feed speed 10, the mass meter 11 with the mass sensor 12, installed between the mass meter 11 and the feeding trough, the intermediate feed conveyor with the worker Body 13.1 mechanically associated with a drive 14 provided with a speed regulator 15 which is input connected to the first output frequency filter 16, a second output of which is connected to the input adder 5, and the input - to the output of sensor 12 weight meter 11

Frequency filter 6 is a device that separates the input non-sinusoidal signal TM (t), which carries information about the mass change on the sensor 12, into two output with given frequency ranges Ium, (t) and ISbK2. (T) The block diagram of the frequency filter 16 depends on the filtering method used and the element base used. You can, for example, use an electrical filter and digital filters on integrated circuits and microprocessors.

The frequency filter 16 contains a driver amplifier 17, a block 18 for dividing the input signal according to specified frequency characteristics, blocks 19 and 20 amplification and matching with low and high respectively.

A change in the block diagram leads to a change in the algorithm of operation of the frequency filter 16. In any case, the input and output signals should correspond to those shown in FIG. 3,

As speed controllers 4 and 5, thyristor frequency transducers of the TPRD type can be used.

The adder 5 includes input signal amplifiers 22 and a summation unit 23.

The device in which the method of distribution of feed is carried out, works as follows.

Upon receipt of the first portion of the feed from the receiving funnel 1 to the meter 11, its sensor 12 triggers and starts drives 3 and 14. Drive 3 starts to sweep the working body 2 of the feeder at a speed determined by the signals coming after summation IdCh9 by adder 5E from the setters feeding the feed 6, the number of animals 7, the feeding front 8, the performance of the feeder 9, the feed speed 10, and the second output of the frequency filter 16. The drive 14 begins to move the working member 13 of the feed gygro-intermittent conveyor at a speed determined by The signal received from the first output of the frequency filter 16, the input of which is connected to the output of sensor 12, mass meter 11. In the process of operation of the feed line of sensor 12, mass meter 11 receives a full signal, characterizing the uneven feed flow, which is divided by frequency filter 16 into two components, one of which (high frequency) controls the speed controller 15, and the other (low frequency) enters the adder 5, which controls the speed controller 4. The speed controllers 4 and 15 affect the drives 3 and 14, which change the speed of movement of the working bodies 2 and 13 of the feed element and the feeder.

When the working device 2 reaches the end position (the last animal), the actuators 4 and 14 are switched off by the operator. Therefore, the method of distribution of food to animals allows 51

It is necessary to take into account both the low and high frequency components of the input signal characterizing the mass of the incoming feed, i.e. the uniform distribution of feed along the working body 2 of the feeder is regulated by two signals. Each output component of the original signal at the output of the frequency filter 16 carries information about the change in the mass of the feed on the mass meter 11, i.e. instantaneous performance (feed velocity through the mass meter 11 is constant).

Thus, the given method of feeding the animals and the device for its implementation allows to achieve an even distribution of the feed stream along the working body of the feeder, which in turn makes it possible to provide all animals with adequate food and in equal amounts to increase their productivity.
