Description

The invention relates to a weight measuring technique and is intended to determine the weight of animals contained in common machines having auto drinkers,

The purpose of the invention is the determination of the accuracy of determining the average daily weight gain of animals and the forgiveness of their culling.

Figure 1 shows the block diagram of the device; Fig 2 - schematic block marking animal

The device contains a platform 1 installed in the machine, a weight-measuring unit 2, which has a weight-to-sig- nal converter 3, w5 an autodrinker 4, a recording circuit 5, and a marking unit b. The weight measuring unit 2 also has an animal presence sensor 7 and a signal processing resolution unit 8, and the recording circuit 5 is equipped with a comparison unit 9 of the measured and minimum allowable weight; a register 10 of the minimum allowable weight, an additional register 11 (average weight register for the next 24 hours), the counter 12 of the number of weighings, the summation unit 13, the average weight calculation unit 14, the weight gain calculation unit 15, the calculation unit 16 calculates the minimum allowable weight, the timer 17, the zeroing circuit 18 and the data logger 19.

The marking unit of animals 6 (FIG. 2 contains a spring 20, an electromagnet 21, a goo 22, a piston 23, a measuring cup 24, an outlet 25 and an inlet valve 26, a dye tank 27, an outlet 28,

The sensor 7 of the animal has a mechanical connection with the push pedal of the automatic drinker 4 (not shown). The weighing unit 2 is mounted directly at the automatic drinker 4. The unit

8 connected to the outputs of the block inputs

9 comparison of the measured weight with 1 is the minimum allowable and the counter 12 is the number of weighings, and the inputs with the outputs of the converter are 3 weights with the signal and the sensor 7 have a slot. Comparison unit 9 is connected to the output of register 10, and the outputs to the inputs of the marking units 6 and summation TOR, the latter is connected to the output of the average weight calculation unit 14, the inputs of which are connected to the outputs of the counter 12 and timer 17, and the outputs - to the inputs of the weight gain calculation unit 15 and the register 11, which by its outputs is connected to the inputs of the weight gain calculation unit 15,

the data recorder 19 and the minimum permissible weight calculation unit 16 connected by the output to the input of the register 10, the outputs of the zeroing circuit 18 are connected to the counter inputs

12 and the block from intermixing 13, and the input to the output of timer 17, the output of block 15 is connected to the input of data recorder 19.

The device works as follows.

Before the device is put into operation, the measuring cup 24 is filled and the dye connecting pipelines are then pressed several times until the dye appears on the outlet nozzle 28. After the device is put into operation, the animal will go to the automatic drinking machine 4. platform 1. As a result, the weight of the animal is sensed by the converter 3, the signal of which is fed to the input of the processing resolution block 8

the signal, but does not pass to the recording circuit 5, since there is no resolution signal from the sensor 7 of the presence of an animal, which comes in when the animal presses the autodrinker pedal 4. The signal from the sensor 7 to the Chinese of the animal’s signal, as a result, the information about the weight of this animal enters through block 8 from converter 3 into recording circuit 5, the readings of counter 12 of the number of weighings increase by one. The information is fed to the comparison block 9, where a comparison is made to a given weight with a weight arriving from register 10 of the minimum acceptable weight. If the weight of the animal is less than the minimum allowable, then a signal is given to the marking unit 6, under the action of which the electromagnet 21 is triggered and the piston 23 is pulled up by a ton ha 22. Pru-: “ina 20 is compressed. The dye from measuring cup 24 through the exhaust valve 25 enters the outlet nozzle 28, which is located above platform 1, and, following from it, falls on the back of the weighed animal, painting it. Duration

the signal from block 9 is limited. After the cessation of the signal, the piston 23 returns to the rest position under the action of the screw 20, and the cup 24 is filled with dye from the tank 27 through the inlet valve 26. When the next signal from block 9 is applied, the device is similar. In addition, the weight information of the animal is summarized in block 13 with data on the weight of animals weighed up to this point. With the approach of subsequent animals to the auto-drinking device, the operation of the device and the sequence of information processing are similar.

At the end of the day, according to the signal from timer 17, block 15 determines the average weight per day, dividing the total ve from block 13 by the number of weighing from counter 12, block 15 determines the weight gain per day comparing the average weight for two adjacent days from block 14 and register 11. Thereafter, the average weight information from block 14 is written in register 11. Then the information goes to block 16, where the value of the minimum allowable weight is determined as the product of the average animal weight per day and the coefficient of 0.75, and then remembered in register 10. Timer 17 gives s drove to circuit 18, which zeroed the counter 12 and block 13, and the average weight and weight information is recorded by the data logger 19. On the next day, the operation of the device and the sequence of information processing are similar.

Thus, the device allows to increase the accuracy of determination .-: the average daily weight gain, as the weight of not only the heaviest and lightest animal is studied, but the weight of all animals that come up to auto-drinking and reduced labor costs for maintenance, simplifying the process of culling lagging behind in growth animals.
