The invention relates to agricultural instrumentation, in particular, to devices for counting seeds of agricultural crops. The purpose of the invention is to increase the reliability and performance of the device.

Figure 1 shows the proposed device, a common VSh1; figure 2 is a section in figure 1; on fig.Z - functional diagram of the device.

The device comprises a housing 1 in which a container 2 is installed for loading seeds. On the case it is fixed 5 on the partition 3 with the upper part 4 of the partition. The housing 1 has a left wall 5 and a right wall 6, on the housing 1 a first guide 7 and a second guide are mounted. 8, a seed disc 9, an electric motor 10 with a shaft 11. On the surface of the disc 9 for seed feeding, jacks 12 are filled. On the first axis 13, there are 20

sensor 41 sets the required number of seeds in the sample to be counted. The agitator 14 and the valve mounted on the first axis 13 are driven back and forth by an electric motor 10 with the shaft 11. At the same time, the disk 9 rotates to feed the m with the slots 12. Seeds along the first guide 7 and the second direction 8, the valve 17, located on the second axis 16, receives a cut valve 15 into the slots 12. A partition with an arcuate upper part 4 is installed between the left wall 5 and the right wall of the housing 1, the torus prevents slipping of miniature slots 12. Then nests seeds with the help of the third direction the solid guide 20 is pushed onto a separation mechanism 21 consisting of triangular prisms 22 arranged in a chess pattern.

with a valve 15. On the second axis 16 there is a cleaning valve 17 with a handle 18. Under the disk 9 for feeding the seeds, a third guide 19 and a fourth guide 20 are installed. Between the right wall 6 of the housing 1 and the partition 3 there is a mechanism 21 division consisting of correct-. triangular prisms 22 and n vertical lines kmtsih 23, forming with partition 3 and right wall 6 n + 1 channel 24 for seeds with holes 25 in which the first valve 26 and the second valve 27 are connected, connected to the first electromagnet 28 and second an electromagnet 29. Between the left wall 5 of the housing 1 and the partition 3 is installed the first receiving capacitance 30, and between the partition 3 and the right wall 6 of the housing 1 the second receiving capacitance 31 is installed. In the channels 24 there are photosensors 32 connected to amplifiers 33, triggers 34, multiplexer 3 5, counter 36, decoder 37, digital display element 38, first comparator 39, second comparator 40, unit 41, pulse generator 42, binary counter 43, and element 44.

The device works as follows.

The seeds prepared for counting are loaded into the container 2 of the housing 1, 30

triangular prisms 22 are scattered and enter channels 24 for counting. The passage of the seeds is recorded by the photon sensors 32, and the pulses are fed to the inputs of the amplifiers 33, and from their outputs to the inputs of the flip-flops 34, turning them from state O to state 1 The outputs of the flip-flops 34 are cyclically polled using a binary counter 43, 42 pulses and a multiplexer 35, the oscillator frequency of the 4 pulses generator significantly exceeds the maximum frequency of passage through channels 24. From the multiplex output, the pulses go to the input of the counter 36, which thus fixes the total number passageway through all channels 24 sem. The information is displayed on the element 38 and the dictation, which receives signals from the counter 36 through the decoder 37. At the end of each polling cycle, the triggers 34 through the element 44 are brought to the O state. At the end of the counting, a given number of thousand, hundreds and ten From the second comparator 40, a signal is sent to the first electromagnet 2 which closes the first valve 2 installed in the openings 25. After the predetermined number of units is reached, the second electromagnet 29 is triggered by the signal from the first comparator 39 and closes the last (n + 1) - and

sensor 41 sets the required number of seeds in the sample to be counted. The agitator 14 and valve 15, mounted on the first axis 13, are driven back and forth by an electric motor 10 with the shaft 11. At the same time, the disk 9 is driven to rotate to feed the seeds with the slots 12. Seeds along the first guide 7 and the second direction 8, through the cleaning valve 17 located on the second axis 16, flow through valve 15 into slots 12. Between the left wall 5 and the right wall 6 of the housing 1 there is a partition 3 with an arched top 4, which prevents the slots 12 from slipping. Then from the nests of 12 seme and via a third guide 1U and fourth guide 20 arrive at the separation mechanism 21, consisting of spaced staggered triangular prisms 22.

triangular prisms 22 are scattered and enter channels 24 for counting. The passage of the seeds is recorded by the photosensors 32, and the pulses go to the inputs of the amplifiers 33, and from their outputs to the inputs of the flip-flops 34, transfer them from the state O to the state 1 The outputs of the flip-flops 34 are cyclically polled using a binary counter 43 controlled by a generator 42 pulses, and multiplexer 35, and the oscillation frequency of the generator 42 pulses significantly exceeds the maximum frequency of the passage of seeds through the channels 24. From the multiplexer output, the pulses arrive at the input of the counter 36, which thus permanently fixes its number passing through all channels is 24 seeds. The information is displayed on the display element 38, which receives signals from the counter 36 through the decoder 37. At the end of each polling cycle, the triggers 34 through the element 44 are brought to the state O. At the end of the counting, a given number of thousands of hours, hundreds and tens of seeds from the second the comparator 40 receives a signal to the first electromagnet 28, which closes the first valve 26 installed in the openings 25. After the predetermined number of units is reached, the second electromagnet 29 is triggered by the signal from the first comparator 39 and overlaps the last (n + 1) -and

24 with the second valve 27. After that, all the seeds begin to flow instead of the second receiving tank 31 into the first receiving tank 30. After the end of the counting, the electric motor 10 is turned off,

If it becomes necessary to switch to another seed pattern, then the counter is cleaned as follows. By turning the knob 18, the cleaning valve 17 opens, at the same time the electric motor 10 is turned on and drives the disk 9 to feed the seeds and the seeds from the tank 2 fall into the first receiving tank 30, and the seeds left at the time of the termination of the count in the slots 12, through the channels 24 get onto the first 26 and second 27 shutters closed and through them into the first receiving container 30. The separation mechanism 21 is made in the form of regular triangular prisms 22, which are arranged in a checkerboard pattern, with an edge up, with an interval corresponding to the size of Here, along the contour of an equilateral triangle with vertices formed by regular triangular prisms 22 and sides along which n regular triangular prisms 22 are placed. The number of channels 24 formed by vertical guides 23, partition 3 and right wall 6 of housing 1 is equal to n + 1, the number of photosensors 32, amplifiers 33, triggers 34 is n + 1.

The technical and economic effect from the use of the invention consists in increasing the productivity and reliability of the seed count.
