The present invention relates to an improved device of a seeding
machine or a fertilization seeding
machine in agricultural machines, and discloses a driving
control signal collecting device for a seed or
fertilizer discharge groove wheel of the seeding
machine or the fertilization seeding machine, roller wheels are arranged on the seeding machine or the fertilization seeding machine, the roller wheels are contacted with the ground, the roller wheels rotate along with the forward moving of the seeding machine or the fertilization seeding machine, and electrical signals which are outputted while the roller wheels rotate are transmitted to a driving control device of the groove wheel (12) of the seeding machine or the fertilization seeding machine. A rotating shaft (8) of the roller wheels collects the electrical signals by a rotation speed sensor to transmit to the driving control device of the groove wheel (12) of the seeding machine or the fertilization seeding machine. The rotating shaft (8) of the roller wheels is provided with a
grating disc (4), an
infrared probe (10) on the side of the
grating disc (4) collects the electrical signals to transmit to the driving control device of the groove wheel (12) of the seeding machine or the fertilization seeding machine. The driving
control signal collecting device has the
advantage of simple structure, the whole driving
control signal collecting device combines two technical characteristics, the driving control
signal collecting device can sensitively and accurately reflect and collect actual operation conditions of the seeding machine or the fertilization seeding machine, also can conveniently and quickly transfer the actual operation conditions to the driving control device of the groove wheel of the seeding machine or the fertilization seeding machine to obtain accurate signals so as to achieve the purpose of the driving control
signal collecting device.
