Crank connecting rod power-cutter type anti-plugging device

Abstract

The invention relates to agricultural machinery, in particular to a power-cutter type anti-plugging device used on a non-tillage seeder. The crank connecting rod power-cutter type anti-plugging device comprises a stand (1), a ground wheel (8) arranged on the stand (1), a speed reducer (15) and a furrow opener (17) and is characterized in that symmetrical power driving mechanisms (29) are arranged at two sides of the speed reducer (15) at the front part of the stand (1); a crank connecting rod cutter mechanism (28) is connected with the symmetrical driving mechanisms (29) through a crank short shaft (7); a combined cutter working component (28) is positioned in front of the furrow opener (17); one end of a stand connecting rod (2) is movably connected with the stand (1), and the other end of the stand connecting rod (2) is movably connected with a U-shaped groove on a combined cutter; and constrained by the stand connecting rod (2), the combined cutter moves back and forth along the vertical direction under the driving of a power crank.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a power cutter type anti-blocking device used on a no-tillage seeder. Background technique [0002] At present, the anti-blocking devices of no-tillage seeders in my country mainly have two forms: passive anti-blocking and power-driven anti-blocking. Patent No. ZL98218325.9 "Gear-tooth anti-blocking device for no-tillage mulching seeder", patent No. ZL200720033098.6 "Elastic-tooth anti-blocking device for no-tillage seeder", and patent No. 200420002414.X "Deep fertilization for no-tillage corn seeding The anti-blocking device of the depth-limiting grass cutter in the pine combined operation machine, the patent number 01222698.X, the anti-blocking device of the grass pressing wheel in the "less-tillage mulching seeder", the patent number 200420002414.X "the combination of corn no-tillage sowing and fertilization The double-toothed grass-turning anti-blocking device in the "Working Machi...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method that can effectively cut off the straw and root stubble in front of the ditch opener to prevent blockage in front of the shovel handle of the ditch opener, thereby completing fertilization and sowing and improving the quality of sowing; Realize the row-to-row cutting operation of wheat and corn straw in flat cropping and ridge cropping, and adjust the angle between the cutting knife and the forward direction of the machine according to the amount of residual stubble, which overcomes the ability of the previous anti-blocking device to adapt to different straw coverage in the field Crank-connecting rod power cutter type anti-blocking device with poor and poor versatility
