AUTOMATED SYSTEM OF IN-LINE MEASUREMENT OF GRAIN YIELD Russian patent published in 2018 - IPC G01F1/30 

FIELD: agriculture; engineering.

SUBSTANCE: invention relates to agricultural machinery and can find application in the harvesting of crops by a grain combine when implementing the technology of precision farming. Automated system for the in-line measurement of grain yield includes body 1, flow splitter 2 in the form of an inclined plane, flow stabilizer 3 measuring chamber 4, capacitive sensor 5, temperature sensor 6 and strain gauge 7. It is new that the flowmeter of the general grain flow is made in the form of metal bracket 8 fixed to body 1 with two coaxial threaded holes, and two pressure transducers 9, 10 with frequency signal outputs are clamped in them to meet each other, clamping measuring chute 11 having fixed point of support 12 on body 1. Signal outputs from sensors 9 and 10 are fed to the D and C inputs of the D flip-flop 13, output of the D flip-flop is connected to one of the inputs of frequency input module 14, and the output of humidity sensor 5 is connected to its other input. Output of the frequency input module 14 is connected via the RS485 interface to on-board computer 15. Same signal is received from temperature sensor 6 and load cell 7 digitized by analog input module 16. Onboard computer 15 is equipped with navigator 17, flash memory 18 and a GSM/GPRS cellular communication modem 19.

EFFECT: facilitating the solution of the problem of precision agriculture technology in equalizing the fertility of fields with differentiated fertilizer application, and, as a result, increasing the yield of agricultural crops and reducing the environmental burden on the environment.
