Abstract
Corn stub land clear straw monomer cutter tooth belongs to agricultural machine; Installing single sword circular arc sawtooth knife plate with installing to be connected by torsion web plate on the plane handle of a knife bottom of through hole, being fixedly mounted with curved surface arc spoon plate on single sword circular arc sawtooth knife plate bottom, described torsion web plate reverses 5-8 �� of angle relative to plane handle of a knife; This monomer cutter tooth is rationally novel in design, and structure is simple, cheap for manufacturing cost, it may also be useful to reliable, operation quality is good, and consumption of power is little, and the clear straw operation being especially applicable to corn stub land uses.
Description
Technical field
The invention belongs to agricultural machine, relates generally to a kind of being fitted in and determines axle steel-tooth formula stub land kind bed and reorganize and outfit on facility the monomer cutter tooth for the clear straw operation of corn stub land.
Background technology
In the yellow Huaihai Zone of China, autumn corn stub land is carried out straw clearly when covering straw no-tillage seeding operation, usually adopt the firm tooth-like stub land kind bed of axle of determining developed by applicant to reorganize and outfit facility and complete operation. In production operation is put into practice, the applicant finds to cover straw structure of the cutter body defect due to clear straw, cause determining the firm tooth-like stub land kind bed of axle and reorganize and outfit facility when corn stub land supernatant straw operation, the rate in small, broken bits except stubble rate and root stubble, stalk of corn stubble is not high, plant bed and reorganize and outfit quality difference, restricting and have impact on seeding operation effect, after sowing, seedling rate is low.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing, in conjunction with the actual needs of agriculture production operation, design provides the corn stub land clear straw monomer cutter tooth of a kind of new texture, reaches and improves corn stubble except stubble rate and root stubble, stalk rate in small, broken bits, the object that ensures kind of bed quality.
The object of the invention is achieved in that a kind of corn stub land clear straw monomer cutter tooth, installing single sword circular arc sawtooth knife plate with installing the plane handle of a knife bottom of through hole is connected by torsion web plate, described single sword circular arc sawtooth knife plate bottom is fixedly mounted with curved surface arc spoon plate; Described torsion web plate reverses �� angle relative to plane handle of a knife, and described �� angle is 5-8 ��, so far forms corn stub land clear straw monomer cutter tooth.
The invention is rationally novel in design, and structure is simple, cheap for manufacturing cost, it may also be useful to reliable, operation quality is good, and consumption of power is little.

Fig. 2 is the left direction view of Fig. 1;
Fig. 3 is the direction view of bowing of Fig. 1;
Fig. 4 is the invention operating principle and operation effectiveness schematic diagram.
In figure, part number illustrates:
1, install through hole, 2, straight line handle of a knife, 3, reverse web plate, 4, single sword circular arc sawtooth knife plate, 5, curved surface arc spoon plate.
Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail. A kind of corn stub land clear straw monomer cutter tooth, installing single sword circular arc sawtooth knife plate 4 with installing to be connected by torsion web plate 3 on plane handle of a knife 2 bottom of through hole 1, is fixedly mounted with curved surface arc spoon plate 5 on described single sword circular arc sawtooth knife plate 4 bottom; Described torsion web plate 3 reverses �� angle relative to plane handle of a knife 2. Described �� angle is 5-8 ��. The optimized angle that described torsion web plate 3 reverses �� angle relative to plane handle of a knife 2 is 7 ��.
During operation, monomer cutter tooth is utilized and through hole 1 is installed is packed in and determines the clear straw that axle steel-tooth formula stub land kind bed reorganizes and outfit facility and cover on straw cutter axle assembly, and rotate and carry out operation. Reversing 5-8 �� of torsion(al)angle of web plate 3, decrease the amount of breaking ground during the cutter tooth operation of this monomer, power consumption reduces; Single sword circular arc sawtooth knife plate 4 improve monomer cutter tooth to stalk, root stubble tear effect, it is to increase broken stubble rate and rate in small, broken bits; Curved surface arc spoon plate 5 reliably, effectively by corn stubble digs out, increased substantially except stubble ability and plant bed reorganize and outfit quality.
