Abstract

An automatic controller based on GPS for the sower in order to apply fertilizer in variable mode is sequentially composed of radio data transceiver, GPS receiver, velicular computer, variable control driver and electrically controlled stepless speed variator. Its control procedure includes such steps as receiving GPS information by GPS receiver to determine the position of sower in field, transmitting the position information to computer, combining the data about applying fertilizer in variable mode with said position information, sending instructions to the variable control driver and controlling the drive ratio of fertilizer-discharging system.

Description

technical field [0001] The present invention relates to an agricultural machine, in particular to a GPS-based planter variable fertilization automatic control device. The field position of the planter is determined by the vehicle-mounted GPS, and the position information is transmitted to the computer through a serial interface. The variable fertilization data is combined with the field position information to send instructions to the variable control driver, and the variable control driver controls the electronically controlled continuously variable transmission to change the transmission ratio of the seeder fertilizer discharge drive system to achieve the purpose of variable fertilization. Background technique [0002] The fertilizer discharge power of the traditional seeder depends on the transmission of the ground wheel, and the change of the fertilizer discharge amount is realized by changing the fertilizer discharge transmission ratio. Contents of the invention [00...
