Row-aligning rootstalk cutting machine for corn rootstalks

Abstract

The invention discloses a row-aligning rootstalk cutting machine for corn rootstalks. The row-aligning rootstalk cutting machine comprises a stander, a spline shaft, a transmission box, a transmissionshaft group, an upper side plate, a belt wheel group, a cutter shaft, a plurality of sleeve cutter seats, a main rootstalk long cutter, a main rootstalk middle cutter, a main rootstalk short cutter,a left-bending long cutter, a left-bending middle cutter, a left-bending short cutter, a right-bending long cutter, a right-bending middle cutter, a right-bending short cutter and a positioning locking bolt, wherein the stander is an existing rootstalk cutting machine stander; the transmission box is fixedly mounted on the stander; the upper side plate is welded to the right side of upper part ofthe stander; the transmission shaft group is fixedly mounted on the right side of the transmission box; the right end of the transmission shaft group is connected with the upper side plate; the belt wheel is fixedly mounted on the right side of the upper side plate; the cutter shaft is mounted on a support plate under the stander, and the right end of the cutter shaft is connected with the belt wheel group; the sleeve cutter seats are uniformly mounted on the cutter shaft along the axial direction; and long and short cutters are combined with straight and bent cutters. According to the row-aligning rootstalk cutting machine, the layered row-aligning rootstalk cutting of corn rootstalks can be realized after the corn straws are crushed, so that the power of the rootstalk cutting machine isreduced, and the rootstalk cutting machine can meet the agricultural requirements.

Description

technical field [0001] The invention relates to a farmland leveling device, in particular to a corn stubble breaking machine in rows. Background technique [0002] The corn stalk grinder can only crush the corn stalks above the ground, but cannot crush the secondary roots of the corn stubble below the ground. Although the rotary tiller can crush the soil below the ground, the stubble breaking effect is poor. After rotary tillage Corn stubble is mixed in the crushed soil, which affects the planting of crops and the germination rate of crops. At present, the Chinese invention patent "Banded Stubble Broken Soil No-tillage Seeder" with the application number CN201610497573.9 has different row spacing adjustments, but the blades have the same length, and the blades are not spirally arranged. The blades mainly throw the stubble to the soil. side, instead of breaking and cutting the stubble, and the existing corn stubble breaker has a large stubble breaking area, and the corn stub...
