Description

One covers the adjustable full straw covering plot no-tillage wheat seeder of straw amount
Technical field
The present invention relates to the seeder in agricultural machinery, be specifically related to the improvement mechanism of Work machine of no-tillage seeding Semen Tritici aestivi after stubble Semen Maydis before being suitable for, Oryza sativa L., cotton crop results.
Background technology
China's corn-wheat, Oryza sativa L.-Semen Tritici aestivi, Cotton Gossypii-Semen Tritici aestivi crop rotation district, sowing in time Semen Tritici aestivi is needed after preceding crop Semen Maydis, Oryza sativa L., cotton harvesting, owing to after mechanized harvest, field has retained a large amount of Semen Maydis, Oryza sativa L., cotton stalk, bring bigger difficulty to lower stubble Semen Tritici aestivi Mechanization sowing.
The patent No. discloses 201210397462.2 " a kind of broken straw, clear straw, fertilising, sow, cover straw Multi-function equipments ", the sowing when front stubble is the straw amount such as Semen Maydis, Oryza sativa L. big crop, cover the straw stalk pulverized, solve the defect of prior art, but during the front stubble of the no-tillage seeding crop that to be the straw amount such as Semen Maydis, Oryza sativa L. big, as straw all covers, or all also field there is problems in that
1, straw all also behind field Nitrogen In Soils element not enough so that microorganism and crop contention nitrogen, result Straw decomposing is slow, and wheat seedling yellow because of nitrogen stress, Seedling are weak, undergrowth;Make soil become too loose, macrovoid too much, cause running the wind loss of moisture, affect germination and grow, make Semen Tritici aestivi take root and loosely occur hanging root.
2, blocked up to easily cause early stage low temperature on the low side for improving straw mulching, affects the supply of nutrient;Low in fertility or when not applying fertilizer, growth of seedling is not good enough, cause that Seedling is yellow, Seedling is weak, make Seedling growth promoter postpone even dead Seedling.
A technical scheme behave that can overcome above deficiency is wished for problem above this area.
Summary of the invention
Present invention aims to above-mentioned the deficiencies in the prior art, a kind of full straw covering plot no-tillage wheat seeding machinery that can regulate and cover straw amount is provided, realize full straw covering plot no-tillage farming and cover the adjustable part flow arrangement of straw amount, realize part straw-returning, part improving straw mulching, and crop-residue incorporation and the adjustable device of overlay capacity ratio.
The purpose of the present invention is realized by following technical scheme.
One covers the adjustable full straw covering plot no-tillage wheat seeder of straw amount, it is characterised in that: following configuration after certainly going to:
Being connected the swivel knife shaft of the horizontal wide cut box-type crushed stalk clear straw machine vertical with direction of travel by tractor motive power output shaft, configure many broken straw cuttves on cutter shaft, the rear of broken straw cutter is a horizontal screw feeder;
Upper encloser panel between broken straw cutter and horizontal screw feeder is laterally offered adjustment seam, regulating seam side secured adjusted seat bar, in regulating seam, inserts the adjustable plate of rectangle, bolt adjustable plate is fixed on adjustment seat bar;
Adjustable plate has stopped the straw stalk horizontal screw feeder of entrance that part broken straw cutter is pulverized;
Offering multiple screw on adjustable plate, bolt connects the screw of diverse location, can change adjustable plate and insert the degree of depth of upper encloser panel, regulates the straw stalk stopping pulverizing and enters the amount of horizontal screw feeder;
The outfan configuration blower fan of horizontal screw feeder, delivers to above wheat fertilizing seeder by the road backward, and the straw scope shed out is suitable with wheat fertilizing seeder width on width;
Wheat fertilizing seeder is configured at the rear of described horizontal screw feeder.
Adopt the technical program, the upper encloser panel between broken straw cutter and horizontal screw feeder is laterally offered adjustment seam, regulating seam side secured adjusted seat bar, in regulating seam, insert the adjustable plate of rectangle, bolt adjustable plate is fixed on adjustment seat bar;Adjustable plate has stopped the straw stalk horizontal screw feeder of entrance that part broken straw cutter is pulverized, and thus regulates part straw-returning, part improving straw mulching, reaches the purpose that can change crop-residue incorporation and overlay capacity ratio.
Further, a described adjustment seam is divided into some sections, and adjustable plate is some pieces accordingly.
Further, described adjustment seat bar is flanging angle steel, and side is fixed on upper encloser panel, and opposite side offers screw.
Beneficial effects of the present invention, pass through technique scheme, adjustable plate has stopped part straw stalk and has entered horizontal screw feeder, part straw directly returning to field, part straw is covered by screw feeder and pipeline, crop-residue incorporation and overlay capacity ratio can be changed, overcome and all go back field such as straw or all cover Problems existing.The technical program simple in construction, cost is low, and assembling is simple, reliable, and effect is notable.
