A track chassis planter frame suspension structure

Abstract

The utility model discloses a caterpillar chassis seeding machine frame suspension structure, specifically relates to seeding equipment technical field, including two caterpillars, a plurality of caterpillar plates in the caterpillar are swingly arranged through caterpillar pin, and the driving wheel of caterpillar inner side end portion is installed with chassis through bearing. The utility model changes the position of sowing assembly by electric push rod to do the stretching movement, when electric push rod elongation, push support arm rotates around hinge point, because support arm is connected with sowing assembly, sowing assembly also will drop along with the rotation of support arm, and support arm rotates clockwise around hinge, drives sowing assembly to carry out up and down movement, guarantees that sowing assembly is in parallel state with sowing ground every moment, improves sowing quality, and allows the relative motion between each part, and sowing operation is carried out through the drop of sowing assembly, and in the whole movement process, two support arms always keep parallel, ensure that sowing assembly can stably contact and sow to ground.
