DEVICE FOR AUTOMATIC CONTROL OF TECHNOLOGICAL PROCEDURE OF AGRICULTURAL MACHINE Russian patent published in 2013 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: device comprises n impulse photoelectric sensors for measuring the rate of seeding (SS), n sensors for measuring the rate of granular mineral fertiliser application (SF), two summing circuits of signals of SS and SF 1,2, the control unit (controller) 4 of seeding and fertiliser application with flash memory 5 and a terminal of operator control 6, a navigator, two generators of control signals 7,8 with actuating mechanisms 10,11 of control of rate of seeding and fertiliser application in the form of electric control drives of effective width of seeding dispenser coils with use of flaps 12,13, the control sensor of minimum seed level (SSL) in the seed hopper, the control sensor of minimum fertiliser level (SFL) in the fertiliser hopper, the control sensor of the elevated state of the openers (CSESO), the control sensor of rotation of working bodies (SRWB). At that the SSL, SRWB are connected to the first unit of discrete input 14, CSESO, SFL are connected to the second unit of discrete input 15. The outputs of units of discrete input are connected via RS485 interface to the controller 4, the frequency input module 3 and the terminal of the operator control 6. At that, the SS and SF are made with one channel of registration of the sown material, provided with the memory elements on the capacitor C4 and resistor R5, connected to the inputs of units of discrete input 14 and 15, respectively, and through diode VD2 and capacitor C3 to the outputs of amplifiers.

EFFECT: use of the invention enables to improve the performance characteristics of the agricultural machine in sowing crops.
