Description

Intensive seeder of millet without thinning

Technical field

The utility model relates to a kind of agricultural machinery, especially for the facility of sowing millet.

Background technology

Being commonly called as millet after the millet processing, is one of main small coarse cereals of China, because of it contains abundant nutrition, is subjected to liking of people, has vast market prospect.Because grain is very little, general thousand kernel weight 2.5-3 gram, therefore, seedling is very thin, pushes up extremely fragility of native ability when unearthed.Add the multiple ground of planting in drought and barren of millet, whole ground quality is not good enough, becomes the seedling growing environment abominable, and emerging by colony's symbiosis top soil becomes the essential measure that millet is saved seedling from damage.Often form for saving seedling from damage: the vicious circle of " amount of broadcasting → high density → difficult thinning greatly ".General mu seeding quantity be stay the seedling amount 10-15 doubly, during thinning, thinning person need bend knee and squat down, the step reach of squatting of thinning limit, limit, every mu needs hard-working more than 5 days under burning sun, the slow person of rhythm needs 8-10 days, its labour intensity can't bear the heavy load.Sometimes cause the waste seedling underproduction because of thinning is untimely, finally influence the harvest of millet.Therefore, the labour intensity factor of artificial thinning has become the restriction peasant and has greatly developed one of principal element of millet plant husbandry enthusiasm.To this, domestic many R﹠D institutions improve agricultural tool, to alleviate the labour intensity of peasant's thinning.As the 2BJ-4 type millet precision planter of southeast, former Shanxi agricultural machinery Research Institute, grain seed simple grain can be broadcast equidistantly into kind of a bed.The patent No. is 90210967.7 Chinese patent, discloses a kind of " manpower millet half-precision seeding machine ", and one of its purpose also is in order to alleviate the labour intensity of thinning, and its primary structure is to adopt a seed wheel, reaches the requirement that seed-grain is sowed in smart amount control.Because whole ground of soil difficult quality control, a little less than the again for a short time native ability in top, back of emerging of seed-grain, individual plant or a small amount of millet seedling are difficult to push up soil and emerge, and emergence rate is very low as a result, soil insect pest factor usually causes the phenomenon of being short of seedling in addition, and existing seed Precision Seeding facility are difficult to satisfy the needs of producing reality.Millet not thinning after planting or few thinning become the important topic on the agricultural already, the many R﹠D institutions in the whole nation have carried out primary study, in order to solve this difficult problem, allow this important food resource of millet fully be developed, the seedling thinning seed has been studied successfully in the tackling key problem in nearly ten years of academy of agricultural sciences, Shanxi Province millet research institute process.To the presowing treatment of seedling thinning seed, broadcast the middle back of burying and equally emerge with other seed, help millet seedling top soil, but be natural death after emerging.Also can the seedling thinning seed not carried out presowing treatment, and normally sow, wait and spray a kind of medicament along row of seedlings again after emerging, the seedling that the seedling thinning seed sends is dead voluntarily immediately.The millet seedling survival that need to keep the like this continued growth of getting off no longer needs thinning.Yet,, also do not have special-purpose supporting seeding machinary at present though this seedling thinning seed provides condition for realizing no thinning sowing.Though, also can utilize existing precision sower after changing the kind hole on the big seed wheel, to sow, also there are some problems.At first, existing sower all is the single packing list seed wheel of planting of employing, and perhaps single structure of planting a plurality of seed wheels of case just must fully be put into kind of a case after the mixing with millet kind and seedling thinning kind during use by a certain percentage.Though millet kind and seedling thinning kind have been carried out abundant mixing, be difficult to also to guarantee that each plants the ratio of millet kind and seedling thinning kind in cave, and the millet kind is difficult to separate after finishing kind with the seedling thinning kind, it is inconvenient to come for the conserving species subband; Secondly, common sower now, all similar as the seeds elimination structure that sowers such as corn, peanut, bean or pea adopt, mechanism is more complicated all, and especially ejector blade mostly adopts elastomeric element, and time one is long tired easily and break down, and the reliability that pushes away kind is not high.As: the patent No. is 89202611.1 Chinese patent, discloses a kind of " manpower corn precision drilling fertilising multi-purpose machine ", and it adopts the elastic force seed pushing wheel to prevent card type.Cause elastomer fatigue easily after long-time the use, correct return influences and pushes away kind of an effect.Simultaneously, because elastomer is a movable part, frequent movement breaks down easily during use, and the reliability of work is not high.

Summary of the invention

The purpose of this utility model provides a kind of intensive seeder of millet without thinning, and this intensive seeder of millet without thinning is precision drilling millet seed and seedling thinning seed simultaneously, and is difficult for breaking down during sowing, the reliability height that it pushes away kind.

The technical solution of the utility model is to realize like this, comprise frame, land wheel, plough, press wheel, plant case, chain, discharging tube, scrape kind of a brush and a seeding unit, the land wheel wheel shaft is contained on the frame, the land wheel wheel shaft is connected with the seeding unit axle by chain, plough and press wheel are contained in the frame below respectively, plough is positioned at press wheel the place ahead, plant case and be arranged on the frame top, plant to be provided with in the case and scrape kind of a brush, feed mechanism is positioned at kind of a lower box part, plant the case bottom and be provided with discharging tube, discharging tube is near after the plough, and described seeding unit is made up of two seed wheels, each seed wheel top is provided with independently plants case, feed shaft on two seed wheels is by gears engaged, and one of them feed shaft links to each other with the land wheel wheel shaft by chain, the shared discharging tube of two seed wheels.

Kind hole on another seed wheel of kind boring ratio on seed wheel is big; Described seed wheel is edge-on bowl-shape, and its center is provided with the axis hole of band keyway, is uniformly distributed with kind of a hole on the outer fringe surface of seed wheel along the circumference, and inner peripheral surface is provided with groove along circumference, and this groove communicates with planting the hole, and the width of groove is less than kind of an aperture, hole; Shell one side is fixed with two and pushes away kind of a sheet, and this pushes away kind of a sheet front end and stretches in the groove of seed wheel, and pushing away kind of a sheet front end is arc; Two feed shafts are contained on the bearing bracket stand on the shell.

Because the utility model adopts two seed wheels and two independently to plant box structure, guaranteed that each plants the ratio of millet seed and seedling thinning seed in cave; Seed wheel is provided with groove, pushes away kind of a sheet front end and stretches in the groove of seed wheel, and pushing away kind of a sheet front end is arc.Therefore, pushing away kind of sheet is fixed structure, is difficult for breaking down, and it pushes away the reliability height of planting.The utility model is looked into seedling on the spot and is measured through county's multiple spot test such as in Qin County, Shanxi Province, Tunliu in 2004 after emerging, 8 centimetres of average emergence rate X=1.3～2.1 strains are short of seedling seldom, has reached the requirement of not thinning after millet is broadcast or few thinning.The mu amount of labour used is no more than 0.5 workday, makes a millet thinning difficult problem obtain effective solution.
