Profiling mechanism of rice direct seeder

Abstract

The invention relates to the field of agricultural machinery, in particular to a profiling mechanism of a rice direct seeder.The profiling mechanism comprises a metering device bracket mounted on therear of the rice direct seeder; a plurality of seed metering devices is mounted side by side on the top end of the seed metering device bracket; a ditcher connection frame is fixedly mounted on the bottom end of the seed metering device bracket; a plurality of ditchers is mounted on the ditcher connection frame staggered from the seed metering devices; a support plate is fixedly mounted in the middle of the seed metering device bracket; a lifting frame is mounted on the front end of the support plate; a sleeve is arranged on the lifting frame; the sleeve is hinged to a lifting arm located on the front end of the rice direct seeder; the sleeve is also hinged to an oil cylinder; a switch bracket protruding forward is mounted on the seed metering device bracket; a proximity switch which can move up and down or swing up and down is mounted on the switch bracket; the front end of the proximity switch is of a wedge-shaped structure; a displacement sensor is mounted on the proximity switch; the displacement sensor controls the movement of the oil cylinder to raise the lifting frame; mud is not pushed and blocked during operation of the profiling mechanism, and the profiling mechanism is suitable for improving an existing rice seeder.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a profiling mechanism of a rice direct seeding machine. Background technique [0002] Modern agriculture has basically been mechanized. The front end of the existing rice seeder is usually a working vehicle, and the rear of the working vehicle is equipped with a sowing device. The sowing device includes a seed hopper on the top. , sowing continuously during the process of pulling the sowing device forward by the work vehicle; the sowing device of the existing rice planter is usually hard-connected to the work vehicle, and the terrain in the farmland is often not completely flat. When encountering highly abrupt uplifts, since the sowing device at the rear is hard-connected, it will pass directly through the uplifts. If the resistance is too large, it will not be able to move forward. In actual use, it cannot adapt to the terrain of different fields. Contents of the inventio...
