Description
Technical field
The utility model belongs to agricultural mechanical field, relates to a kind of seeding unit of sower, especially relates to a kind of seeding unit of novel fine grain precision sower.
Background technology
Seeding unit is the core component of sower, and the quality of seeding unit service behaviour directly affects the emergence rate etc. of seeding accuracy, seeding uniformity, seed.
For fine grain crops that seed sizes is little, quality is light such as rape, tobacco, millets, traditional seeding method is with soing with a drill or slipping seed drilling with artificial hand after certain instrument trench digging, this mode disadvantage is a lot, one is because seed is too small, the amount of broadcasting is difficult to accurate control, seeding is uneven, increases follow-up thinning and final singling workload, affects the yield and quality of crop; Two is that seed waste is relatively more serious, increases the cost of seed; Three is that sowing efficiency is low, and production capacity is relatively lower, can not adapt to the requirement of establishing in large scale operation, limit the Mechanization Development of fine grain crop to a certain extent, hinders the expansion of fine grain crop-planting industry.
Existing fine grain precision seeder mainly contains mechanical type and pneumatic type two kinds.Mechanical seed sowing device structure is simple, cheap, stable performance, but machinery integral size is comparatively large, and easily causes extruding and fragmentation to fine grain seed during seeding, and seeding precision is low, cannot adapt to high-speed job.Pneumatic seeding apparatus requires not tight to the appearance and size of seed, seed breakage is few, and complete machine versatility is good, be easy to realize precise sowing, speed of drilling is high, is easy to realize automatic control, but it is with high content of technology, machining accuracy is tight, and power consumption is large, requires good air-tightness and voltage stabilizing, require higher to blower fan system, and fuel oil takes, manufacturing expenses and maintenance cost high, price is relatively high, and peasant is difficult to bear.
Because current used fine grain precision seeder exists above-mentioned deficiency and shortcoming, therefore Optimal improvements seeding unit structure, the seeding quality improving fine grain crop is imperative.
Summary of the invention
In order to overcome all deficiencies and defect that exist in prior art, the purpose of this utility model is to provide a kind of simple and reasonable, easy for installation, low-profile, cheap novel fine grain precision seeder.
It is a kind of novel fine grain precision seeder that the utility model solves the technical scheme that its technical problem adopts, and mainly comprises seeding unit shell 1, seed plate 2, rolling bearing 3, cam 4, screw 5, push rod 6, Compress Spring 7, hairbrush 8, nut 9, bolt 10, packing ring 11.It is characterized in that: the interference of described rolling bearing 3 is installed on seed plate 2, the interference of described cam 4 is installed on the outer ring of rolling bearing 3, and be fixed on seeding unit shell 1 by screw 5, described push rod 6 is fixed between seed plate 2 and cam 4 by Compress Spring 7, described hairbrush 8 is fixed on seeding unit shell 1 by bolt 10, packing ring 11, nut 9, described seed plate 2 is embedded in seeding unit shell 1, described seed plate 2 has three nibs be used for filling kind, the inner circular arc portion of described seeding unit shell 1 is for scraping off unnecessary seed.
In use, be arranged in the Power output rotating shaft of sower, both sides fix position by stopping means to above-mentioned seed dropping mechanism, avoid seeding unit along rotating shaft transverse shifting.
The operation principle of above-mentioned a kind of novel fine grain precision seeder is:
Seed plate is connected with the rotating shaft of exterior power transmitting device, when power occurs, rotating shaft drives seed plate to rotate, seed plate drives bearing inner race to rotate, cam is connected with bearing outer ring interference and is fixed by screw with seeding unit shell, cam keeps motionless, push rod is driven to rotate along cam face while seed plate rotates, when the nibs on seed plate arrive seeding unit shell upper fill kind of region time, nibs starts to fill kind, when being rotated further seeding unit enclosure circular arc portion, scrape off the seed that nibs is unnecessary, and protect the seed in nibs not fall, when continuing to move to cam rise position, push rod pushs out seed inside seed plate nibs, complete seeding, along with being rotated further of seed plate, under the effect of back-moving spring, push rod rebounded to cam radial direction gradually in the cam backhaul stage, be reset to and can fill kind of a state, hairbrush is used for clean nibs, nibs is avoided to block, circulate and so forth, thus realize the process of filling kind and seeding.
The beneficial effects of the utility model are: seeding unit structure is simple, easy for installation, low-profile, cheap, consumed power is low, a Power output rotating shaft can install multiple seed dropping mechanism and work simultaneously, greatly improve sowing efficiency; Rotating speed in the course of the work also by regulating the rotating shaft output speed of exterior power transmitting device to control seed plate, effective control kind of distance, be convenient to the precise sowing realizing fine grain crop, effective saving seed, reduce labour, improve sowing efficiency, increase crop yield, increase plantation family income.
