Description

A kind of hill-drop planter

Technical field

The present invention relates to a kind of hill-drop planter, is the hill-drop planter that a kind of direct seading rice is used specifically.

Background technology

Eighties of last century the fifties northern China once large tracts of land is promoted rice direct-seeding, and rice direct-seeding accounts for 70% before the 1980's of Heilongjiang Province, and southern china also adopted live the sixties.In recent years, along with expanding economy, the between twenty and fifty labouring population in a large amount of rural areas enter the labour market, city, rural laborer's minimizing, and chemical herbicide etc. is extensive use of, the Direct-seeding Rice cultivation presents the situation that develops rapidly again.This technology is compared with traditional paddy rice growing method, link such as saved raising rice seedlings, transplant seedlings, seed rice through soak germinate after directly with the drilling machine sowing, have advantages such as saving of labor, abridged edition, synergy.Existing in the market a lot of paddy planters, most paddy planters are the big machinery that the large tracts of land sowing is used, and its complex structure, volume is big, weight is big, transportation is inconvenient, can't be applicable to the use of small size farmland, China rural area.

Summary of the invention

In order to solve deficiency of the prior art, the invention provides the hill-drop planter that a kind of direct seading rice is used, it is simple in structure, compact, and volume is little, in light weight, transportation, easy to use is fit to the small size farmland and uses, and sowing evenly, and plant is clearly demarcated, helps the paddy rice high and stable yields.

The technical solution used in the present invention is: a kind of hill-drop planter, mainly comprise framework and a plurality of kinds of bank deposits bucket, a plurality of kinds of bank deposits buckets are evenly distributed to be bearing in the framework, its technical characterstic is that described framework upper end is connected a bent axle through bearing block with bearing, bent axle one end connects power input shaft through gear, toothed chain, crankshaft two end is movably hinged two vertical links respectively, and the lower end of two vertical links connects the lifting cross-arm; All vertical cross-under pillar in described a plurality of kinds of bank deposits bucket, pillar is provided with the seed inlet of corresponding kinds of bank deposits bucket bottom, the pillar upper edge pillar direction of seed inlet below is provided with the lifting groove, be with grain tube in the pillar, grain tube from top to bottom is provided with successively and first sows mouthful, lift pin holes and second is sowed mouth, first of the grain tube corresponding setting of seed inlet with pillar of sowing mouthful, grain tube by lifter pin pass lift pin holes, pillar lifting groove is fixedly connected on the lifting cross-arm, second mouth of sowing is arranged at carrier pipe bottom and is the indentation pillar or stretches out the pillar state.After the input of hill-drop planter power, by toothed chain, the gear driven crankshaft rotating, on the vertical links that is movably hinged on the bent axle, following elevating movement, vertical links drives on the lifting strut rail, following lifting, the lifting strut rail drive to connect thereon grain tube in pillar on, following lifting, grain tube rises in pillar and grain tube first is sowed mouthful be communicated with the seed inlet of pillar, grain tube second is sowed bottom mouthful indentation pillar, the seed of kinds of bank deposits bucket bottom storage is successively by the pillar seed inlet, grain tube first mouth of sowing enters grain tube, grain tube descends in pillar and makes grain tube first the stagger seed inlet of pillar of mouth of sowing, grain tube second mouth of sowing exceeds pillar bottom, and the seed in the grain tube is dropped out and sowed by second mouth of sowing.

Further, also be with regulating tube in the described pillar, regulating tube top is provided with fixed pin holes, and pillar top is provided with dowel hole, and fixed pin holes is connected by alignment pin with dowel hole, and the regulating tube bottom is provided with the regulation and control mouth; Described regulating tube does not have the gap and is placed between pillar and grain tube, or regulating tube do not have the gap and be placed in the grain tube, and regulation and control mouthful and seed inlet, the first mouthful position of sowing is corresponding.The sow connection place size of mouth of regulating tube upper and lower lifting control pillar seed inlet and grain tube first in pillar is controlled the seeding quantity of hill-drop planter thus.

Again further, the two ends of described lifting cross-arm also are provided with two lifting sleeves, and the bottom, two ends of framework is provided with two lifting columns, and two lifting column pivot bush units are in lifting sleeve.Lifting column cooperates lifting sleeve to guarantee that the lifting cross-arm rises, descends along fixed-direction.

The present invention utilizes bent axle to drive grain tube lifting in pillar through vertical links, lifting cross-arm to make first of the seed inlet of pillar and the grain tube mouth of sowing be regular and connect and stagger, realize that seed is sowed at interval in the kinds of bank deposits bucket, kind of the density that falls is even, the saving amount of sowing, the plant of emerging is clearly demarcated, ventilation and penetrating light, sick light worm are difficult for lodging less, need not follow-uply fill the gaps with seedlings, promote the high and stable yields of paddy rice, hill-drop planter is simple in structure, compact, volume is little, and is in light weight, transportation, easy to operate, hand labor intensity is low, is fit to the small size farmland and uses.
