Description

Stalk all standing associating screw sowing machine

Technical field: the utility model relates to a kind of agricultural machinery, specifically is straw-returning, rotary tillage and three kinds of function collection of sowing stalk all standing associating screw sowing machine all over the body.

Background technology: along with carrying forward vigorously of China's agricultural machinery subsidy policy, large and middle tractor has formed universalness and has come into huge numbers of families, promotes laying the foundation for the research and development of large-scale supporting agricultural machinery.And agricultural machinery cooperative society develop rapidly and growth impels soil circulation, make arable land large tracts of land scale, intensive cropping become possibility.The a large amount of surplus labors' in rural area transfer causes rural laborer's in short supply and labour's appreciation, and the particularly raising of fuel price in recent years increases substantially peasant's the cost of cultivating, and this has created condition for the popularization of new and effective agricultural machinery.

But since China promoted straw-returning, the area of straw-returning enlarges rapidly to be popularized, but its shortcoming is also obvious day by day.Because after the straw-returning, cover a thick layer of stalk in the field, to pears, raking the soil level results in blockage, have a strong impact on intensive cultivation, and thick during rotary tillage-layer stalk produces very big resistance to burying of rotary blade, stalk also produces a very large impact rotation soil after mixing soil, causes rotary tillage power to increase, and the rotary tillage quality descends.The also remaining a large amount of stalks in the face of land after the rotary tillage, this is also influential to rotary tillage, sowing, results in blockage, broadcast leakage happens occasionally, and causes the disconnected ridge that is short of seedling.Stalk after screwing in soil is maked somebody a mere figurehead soil, causes and runs wind gas leakage, causes a little less than the dead seedling of seedling.And straw cutting apparatus and the rotovator unit inefficiency sold on the present market, consumed power is big, and integrated cost significantly improves.

The utility model content: the purpose of this utility model provides a kind of associating screw sowing machine, it oversimplifies complicated planting process, realize that straw-returning, rotary tillage, fertilising, sowing once finish, reduce production costs and the stalk all standing associating screw sowing machine of peasant's labour intensity.The technical solution adopted in the utility model is: described straw-returning mechanism device is at big side plate 7 front ends, be connected with the rotary tillage mechanism of device by driving wheel 1 at big side plate 7 middle parts, ferti-seeding mechanism device is at big side plate 7 rear portions, and with wheels 11 drivings of compacting the soil.

The beneficial effects of the utility model are: owing to designed straw-returning, rotary tillage and three kinds of function collection of sowing novel type all over the body, can play mutual supplement with each other's advantages after the combination, reduce power consumption greatly, has synergistic function, 3 times workload once can be finished, operating efficiency is enhanced about more than once, and comprehensive energy consumption reduces 50-60%.And compact conformation, energy-saving and cost-reducing environmental protection can be finished the agronomy planting requirement that the unit operation can't be finished.

1, the utility model biggest advantage is exactly the chopping of crushed stalk and secondary, through kuppe stalk is ejected into then that rotary tillage is crossed and seeded ground.Rotary tillage mechanism is not having the clean ground handling of stalk, and rotary blade rotary-cut resistance over the ground reduces greatly, and does not have the soil flowability of stalk to improve greatly yet, and the energy consumption of rotary tillage mechanism can reduce greatly.Ferti-seeding mechanism can improve greatly in the clean ground trafficability characteristic that does not have stalk, also descends greatly by resistance.Because stalk does not mix soil fully, but all cover after planting ground, at first after the crushed stalk, self contain under the large quantity of moisture and ooze, root with the guarantee wheat seed, and prevent soil water evaporation, play the effect that heats soil moisture conservation, can also check winds and fix drifting sand and play environmental-protection function, and certain grass effect of killing is arranged.Be specially adapted to dust storm, the serious area, great Northwest of arid.Promote report and agricultural production experience for many years according to agrotechnical department of the countries concerned, face of land stalk covers and can reduce single cropping irrigation 1-2 water, and this is not a decimal fractions for those arid areas.The winter-spring season behind the wheat cultivation particularly, wind is many especially, and the face of land is exposed, and soil moisture is scraped dried soon, very easily causes wheat seeding to be freezed to death.So the popularization of this machine is to reducing peasant's labour intensity, catching up with short kind early in farming season, positive role is played in the volume increase of keeping a full stand of seedings.

2, straw-returning mechanism is on the basis of traditional straw cutting apparatus, increasing the conversion of rotation stationary knife group and function rolls, by the straw cutting apparatus main shaft stalk is tentatively pulverized the back impelling and carry out the secondary chopping to rotating the stationary knife place, then stalk flow through kuppe by impelling to the exit, outer tangent plane is rolled in the function conversion that promotes to install, make it to rotate, the kinetic energy that high speed stalk stream is laid in converts the mechanical energy secondary to and promotes driving shaft work, can raise the efficiency about 18.8%.Because the rotation stationary knife is installed in outside the pulverizing chamber, has only blade to put in the pulverizing chamber, so cutterhead (blade) can be sufficiently large, is enough to satisfy job requirement.Cutterhead (blade) adopts the high-quality sawtooth pattern to shear cutterhead (blade), and is sharp.The stalk stream that cutterhead (blade) high speed rotating and main shaft impelling are come is relative motion, and its linear velocity of making a concerted effort can reach about 80 meter per seconds, is enough to cut off soft and fine hair.Because rotation being installed in outside the pulverizing chamber of stationary knife do not form installation step, more be difficult for bonding earth again,, but also save power so its chopping effect can improve more.

3, deep soil loosing shovel is at first installed by rotary tillage mechanism on the basis of traditional rotovator.The powerful forward thrust work that deep soil loosing shovel produces when utilizing rotovator work realizes dark pine, can improve general power about 20%, can also as fertilizer sources layering deep placement utensil.At soil impelling mouth place, rotovator back power conversion being installed rolls, power conversion is rolled by a lot of teeth and is formed, when rolling the tooth of outer tangent plane, the conversion of soil block impact dynamic that the rotary tillage shaft high-speed projectile goes out forms the secondary pulverizing, producing thrust promotion conversion lift-over simultaneously moves, the kinetic energy of being laid in of being turned up soil by throwing soil is converted to mechanical energy, and about 35% the power secondary that can also produce the input general power promotes rotary tillage shaft work.
