Description
Technical field
The utility model relates to a kind of corn replay wheatland kind cunette stalk gearshift.
Background technology
In irrigated land, China Yellow River-Huai River region, 1 year two work of Wheat Maize is its essentialspecies implant model.Since entering this century, along with compact compact corn kind large-area applications, this region corn planting density improves nearly 20% left and right compared with the middle and later periods in last century; In recent years, along with popularizing of corn harvest mechanization, a large amount of maize straws of high-density planting stay in replay wheatland top layer, wheat rotary tillage sowing suppression all-in-one makes a large amount of stalks screw in seeding layer in rotary tillage process process, the disk coulter of sower in seeding operation process (being characterized in being difficult for forming blocking up) is planted cunette by the maize straw in seeding layer " rotation incision " again, planting stalk in cunette adulterates serious with soil, this situation often causes: the one, in kind of cunette, plant, native conjugation is poor, at the bottom of causing emergence rate, the disconnected ridge phenomenon of being short of seedling is general; The 2nd, root in kind of cunette, native conjugation are poor, and normal formation hangs the dead seedling of root; The secondary disasters such as the 3rd, because soil microhabitats in kind of cunette is hanged void, wheat seeding root growth is affected, and is unfavorable for that the normal growth of Wheat Seedling and the middle and late growth stage is grown, and normal initiation is non-irrigated, freeze.In order to solve wheat emerge difficulty, the difficulty of keeping a full stand of seedings and reduce Wheat Seedling and raw middle and later periods secondary disaster, domestic scholars has been carried out more research, and the technology of application mainly contains at present: the one, to staying after corn harvest mechanization in the maize straw airing on top layer, field, after 2-3 days, burn; The 2nd, increase substantially seeding quantity (every mu of seeding quantity reaches 35 kilograms); The 3rd, take the mode of pouring water after broadcasting to improve emergence rate, planting percent and slow down the secondary disaster that the outstanding void of soil is brought.By crop straw burning, increase seeding quantity and broadcast after pour water, though have certain effect to improving wheat seeding rate, planting percent and slowing down later stage secondary disaster, increased considerably Wheat Production cost and be unfavorable for that agricultural land soil fosters and apply fertilizer.
Summary of the invention
The utility model object is the deficiency that overcomes above-mentioned prior art, and a kind of stalk amount in kind of cunette that reduces is provided, and production operation cost is low, the corn replay wheatland kind cunette stalk gearshift that operating efficiency is high.
The utility model is arranged between the rotovator and sower of existing wheat rotary tillage sowing suppression all-in-one, supports the use with existing wheat rotary tillage sowing suppression all-in-one.This wheat rotary tillage sowing suppression all-in-one is by before and after comprising successively rotovator, sower and pack roller, and rotovator is connected with tractor-drawn power.
The utility model comprises support and open-minded stalk member; Support comprises crossbeam, the back rest, pedal, left and right longeron and support stalk; Crossbeam two ends are fixed by backing plate and bolt with left and right longeron respectively; Support stalk front end is welded on crossbeam, and support stalk rear end is fixed by bolt and the back rest; Support stalk has three, along rack beam and the back rest, is evenly arranged; Pedal is buckled on longeron and is bolted.The open-minded stalk member of rack beam comprises fork and rotating cylinder, and fork comprises yoke, fork handle and prong; Prong has two, be welded on respectively yoke two ends, fork handle lower end and yoke welding, upper end is fixed by nut and rack beam, fork handle is respectively equipped with one section of screw thread near upper/lower terminal place, the upper-lower position of the position-adjustable fork handle by regulating nut on fork handle screw thread, and then regulate prong embedded depth; Rotating cylinder is provided with circular hole and lower circular hole, and fork handle is through upper and lower circular hole, and rotating cylinder is enclosed within on fork handle, and rotating cylinder upper/lower terminal is fixed by nut and fork handle respectively.
Stalk member totally ten two covers that slit, wherein six covers are evenly distributed on the support back rest, six covers are evenly distributed on rack beam, 12 covers slit stalk member all with sower on the longitudinal contraposition of disk coulter.The fork handle upper end of the open-minded stalk member on rack beam is fixed by nut and rack beam, and the fork handle upper end of the open-minded stalk member of installing on the back rest is welded with backing plate, and backing plate is fixed by bolt and the back rest; Or fix by being arranged on the bolt on disk coulter annex and sower front beam on sower front beam.By the upper-lower position of the adjustable fork handle of screw on backing plate, and then regulate prong embedded depth; The structure of other prong, yoke, rotating cylinder connects identical with the prong of installing on rack beam, yoke, rotating cylinder.
Support is positioned at after rotovator, before sower.The forward and backward two ends of left and right longeron respectively be positioned at the rotovator longeron before support and be positioned on the sower longeron after support and be bolted; The back rest can directly adopt support sower front beam below to substitute.Rack beam by U-steel make, support longeron by square steel make, strut made by i shaped steel.Two prongs are identical with the sown scope of wheat seed with the width of yoke, are about 3.5cm; Prong embedded depth is 5cm, is slightly larger than the sowing depth 3-4cm of wheat seed.
Between rotating cylinder and fork handle, all have certain gap between nut and rotating cylinder, when the stalk moving on guaranteeing in prong operation is close to rotating cylinder, rotating cylinder can rotate, by stalk displacement in the ranks.Rotovator is about 30cm by the reach of support longeron, the open-minded stalk member of installing on sower front beam is 12cm apart from the disk coulter of installing on sower rear cross beam, and the open-minded stalk member of installing on rack beam is about 15cm apart from the disk coulter of installing on sower front beam.
After the utility model and the supporting installation of existing wheat rotary tillage sowing suppression all-in-one, by traction power (large and middle tractor), once can complete rotary tillage, plant the displacement of cunette stalk, sowing and suppression operation.The utility model in the ranks, reduces the stalk amount in kind of cunette by the stalk displacement in kind of cunette, is conducive to kind, soil, and root, native combination, efficiently solve replay wheatland emerge difficulty, the difficult problem of keeping a full stand of seedings, and improved the drought resisting frost resistance of wheat growth middle and later periods.Be connected easyly with wheat rotary tillage sowing suppression all-in-one, operating efficiency is high, and production cost is low.
