Horizontal type weeding wheel anti-block device

Abstract

The invention discloses a horizontal active weeding wheel anti-blocking device used in a no-tillage seeding machine, and belongs to the technical field of agricultural machinery. The whole structure of the device consists of a frame and 2-8 horizontal active weeding wheel anti-blocking elements. The horizontal active weeding wheel anti-blocking elements are arranged in parallel on the square beamof the frame, with the same space from the left side and the right side of a gear box. The power output by a rear shaft of a tractor is transferred to all active square shafts of the horizontal activeweeding wheel anti-blocking elements by the gear box through a belt gear, which causes the horizontal weeding wheels to rotate horizontally on the ground surface to push the met straws to the area between two seeding zones. The weeding wheels are arranged right ahead a furrow opener to prevent the straws from blocking the furrow opener during furrowing operation. The anti-blocking device solves the problem of anti-blocking delay resulting from clearing only after the blockage of the traditional anti-blocking device, ensures the furrow opener finishes the furrowing operation on the straw-freeseeding zone, and is particularly suitable for no-tillage corn seeding machines.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and relates to an anti-blocking device of a horizontal active mowing wheel, which is used on a no-tillage seeder, and is especially suitable for a no-tillage corn seeder. Background technique [0002] In recent years, my country has actively promoted mechanized conservation tillage technology. After a lot of scientific research and field experiments, no-tillage seeding technology has made great progress, and the anti-blocking performance of no-tillage seeders has become more and more perfect. However, the current no-tillage seeder mainly relies on the anti-blocking device installed on the machine tool to remove the stalks blocked on the opener after the machine tool is blocked, so as to prevent further blockage. The main anti-blocking technology of this kind The blocking principle is: after the equipment is blocked, rely on the anti-blocking device to clean up the blocked straw. Th...

However, the current no-tillage seeder mainly relies on the anti-blocking device installed on the machine tool to remove the stalks blocked on the opener after the machine tool is blocked, so as to prevent further blockage. The main anti-blocking technology of this kind The blocking principle is: after the equipment is blocked, rely on the anti-blocking device to clean up the blocked straw. This anti-blocking technology has anti-blocking lag phenomenon. Far wider than the theoretical ditch width, which seriously affects the quality of sowing
