Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to an anti-winding strip soil preparation device.
Background
In order to implement no-tillage or minimal-tillage seeding technology, currently, a bent knife, a chisel knife or a straight knife is mostly adopted to carry out rotary tillage operation on stubble left on an original seed bed before seeding operation, and the knife types not only have the problems of large disturbed soil quantity and power consumption, easy grass winding and high failure occurrence rate, but also cause great damage to soil especially due to deep tillage and deep tillage, thereby influencing the popularization and application of the no-tillage seeding or minimal-tillage seeding advanced agricultural technology; but due to the straw coverage of the original stubble field, the problems of easy blockage, easy grass winding, poor seedbed quality and the like are brought to no-tillage seeding, and the popularization and the application of advanced agricultural technology of protective farming are influenced.
Disclosure of Invention
The invention aims to solve the problems in the prior art, and researches and designs a protective tillage strip land preparation saw-tooth disc stubble-breaking rotary blade with a new structure by combining with the practical requirements of popularization and application of no-tillage or minimal-tillage seeding agricultural technologies, so that the aims of good original ridge stubble-breaking and soil rotary tillage quality, high strip seedbed quality, small operation resistance, few faults and providing technical support for popularization and application of the minimal-tillage and no-tillage seeding agricultural technologies are fulfilled.
The invention aims to realize the purpose that a sawtooth disc stubble breaking cutter is fixedly arranged on a driving shaft, side cutting edges are respectively and fixedly arranged on two side surfaces of the sawtooth disc stubble breaking cutter, an included angle α between each side cutting edge and the radius line of the sawtooth disc stubble breaking cutter ranges from 50 degrees to 60 degrees, the width dimension L of each side cutting edge ranges from 5cm to 6cm, the width dimension H between the outer ends of the side cutting edges on the two side surfaces of the sawtooth disc stubble breaking cutter ranges from 13cm to 16cm, the diameter dimension phi of the sawtooth disc stubble breaking cutter ranges from 46cm to 50cm, and the working surface of each side cutting edge is an arc surface, so that the winding-proof belt disc type land preparation device is formed.
The invention adopts the sawtooth disc stubble breaking cutter to break and cut original stubbles and straws on the ridge seedbed part, and the side cutting edges on the two sides of the sawtooth disc stubble breaking cutter complete the soil rotary tillage and soil breaking operation of the stripe seedbed in the width dimension determined by the two sides of the stubbles, and the sawtooth disc stubble breaking cutter has the characteristics of novel, simple and reasonable structure, low manufacturing cost, small disturbed soil quantity, good quality of the processed stripe seedbed, small operation power consumption and reliable use.

Detailed Description
The invention provides an anti-winding disc type strip land preparation device, which is characterized in that a sawtooth disc stubble breaking cutter 1 is fixedly arranged on a driving shaft 2, side cutting edges 3 are respectively fixedly arranged on two side surfaces of the sawtooth disc stubble breaking cutter 1, an included angle α between each side cutting edge 3 and a radius line of the sawtooth disc stubble breaking cutter 1 is 50-60 degrees, the width dimension L of each side cutting edge 3 is 5-6 cm, the width dimension H between outer end heads of the side cutting edges 3 on the two side surfaces of the sawtooth disc stubble breaking cutter 1 is 13-16 cm, the diameter dimension phi of the sawtooth disc stubble breaking cutter 1 is 46-50 cm, and the working surface of each side cutting edge 3 is an arc-shaped surface.
During operation, external input power drives the serrated disc stubble breaking cutter 1 to rotate through the driving shaft 2, the serrated disc stubble breaking cutter 1 moves forwards under the traction of a power machine, the sawteeth of the serrated disc stubble breaking cutter 1 which rotates and moves forwards cut off crop roots and straws on an original ridge table, meanwhile, the side cutting edges 3 on two sides of the serrated disc stubble breaking cutter 1 which moves in a trochoid track complete rotary tillage soil breaking cultivation on soil on the ridge table, and thus strip seedbeds with the transverse width of 13 cm-16 cm on two sides of the longitudinal center line of the original root stubble are formed on the ridge table.
The included angle α between the radius line of the side cutting edge 3 and the sawtooth disc stubble breaking knife 1 is 50 degrees-65 degrees, the width dimension L of the side cutting edge 3 is 5 cm-6 cm, the rotary tillage and soil breaking operation quality is ensured, the agricultural requirement of seedbed soil is met, meanwhile, the consumption of traction and rotary driving power is selected in a fully reasonable matching mode, the sawtooth disc stubble breaking knife 1 with the diameter dimension phi of 46 cm-50 cm can adapt to and meet the requirement of the largest cutting and stubble breaking depth of the original stubbles on the strip-shaped seedbed, and the applicability is expanded on the premise of ensuring the cutting and stubble breaking quality.
