Abstract

The invention relates to the agricultural machinery, in particular to a variable control device for fertilizing and sowing and belongs to the variable input technology of the fine agricultural intelligent machinery. The variable control device overcomes the defects and solves the problems of an actuating mechanism of a conventional variable control device for fertilizing and sowing and solves the problems of inconvenience use and increased cost caused by an IC card serving as the variable work prescribing information storage medium. The device comprises a singlechip and a GPS or DGPS communication control module connected with the singlechip, wherein the singlechip is connected with a USB memory device read-write control module and a step motor driving circuit; a step motor adjusts and controls the actuating mechanism; the actuating mechanism comprises an impulse stepless speed variator; and the step motor drives an adjusting shaft of the impulse stepless speed variator through a worm wheel-worm reducing mechanism. The variable control device of the invention is specially used for controlling the fine agricultural variable fertilizing and variable sowing work.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to agricultural machinery for fertilizing and sowing, in particular to a variable control device for fertilizing and sowing, which belongs to the variable input technology of intelligent agricultural machinery in fine agriculture. Background technique [0002] "Precision agriculture" is a hot field of agricultural scientific research in the world in recent years. It is an organic combination of existing agricultural production measures and modern high-tech.
