Background technology
Raising the multiple-cropping index is to solve to have a large population and a few land, the not enough important measures of ploughing.At China's Huang-Huai-Hai, after winter wheat results, lower stubble also can plant one the last month of summer peanut, soybean or seeding corn and other crops.But the residual a large amount of wheat stalks in farmland have had a strong impact on the sowing of the second stubble crops such as Peanut, soybean or corn, and the peasant tends to stealthily crop straw burning, sow afterwards, but crop straw burning can cause serious air pollution again, and government prohibites.
A large amount of stalks that after harvesting wheat, the field exists very easily cause traditional no-tillage seeding machine to shovel with extension grass, the heap soil or fertilizer over and around the roots of fertile shovel and block up, and complete machine can't work, and namely allows to sowing, also easily causes the consequences such as frame kind, disconnected seedling.
In addition, lower batch peanut, soybean or seeding corn and other crops after winter wheat results require that more planting early enough is better, if adopt labor cleaning's stalk, waste time and energy, and possiblely will cause peanut, soybean or corn seeding untimely, affect output; Plough deeply after adopting crushed stalk, then the technical measures of sowing after rotary tillage, although can solve field from which wheat has been reaped sowing problem, different facility need to descend ground three to four times, time-consuming taking a lot of work.
For above problem, the industry has proposed patent " straw sweeping and covering device for no-till planters " CN101731033A structure-improved, and this scheme is by whole chain or two chain circulation rotatings, pulls out tooth and is fixed on the chain cocycle and moves, and turns over toward sidepiece and pulls out conveying.Patent " dead axle rigid tooth type servicing device for stubble field seedbed " CN102415233A is separately arranged, and is to configure respectively three to pull out tooth on three axles, and synchronous rotation is in succession turned over toward sidepiece and pulled out, transmits, carries.This two scheme overcomes labor cleaning's stalk expense labour, and the problem that wastes time provides two kinds of no-tillage sower structures, has certain advantage and creativeness.
But, also there are two common deficiencies in above-mentioned two kinds of technical schemes, one, the tooth that pulls out of two technical scheme cleaning stalks is advancing forward when the rotation side direction is carried operation, pulling out tooth, to be subject to simultaneously the power of stirring of side direction relative to stalk back pressure, composite square to the stressed cutter shaft distortion fracture that fractureing or stalk cleaning cutter is installed that very easily causes stalk cleaning cutter, to pulling out the stressed adverse influence of tooth, the situation of often pulling out the tooth bending, be out of shape or fracture in using practice, not only maintenance cost is high, and has a strong impact on the work efficiency in farming season.They are two years old, because above-mentioned two technical schemes are that the stalk side direction is renovated, during first time operation, sidepiece not yet carried out sowing, therefore turn over to side the stalk that pulls out and to play after planting covering effect, and last time field after planting is need to cover the time, but operation is completed, do not have stalk to cover for it again, therefore, these two the existing improvement of defective, improving technologies still fail to solve, and restricted applying of aforementioned two patented technologies, or result of use is influenced, and the user of this area urgently wishes further to improve.
