Abstract
The invention relates to a wheat wide-seed-strip planting uniform seeder. The wheat wide-seed-strip planting uniform seeder comprises a seed tube, protecting plates, separating plates, a baseplate and an auxiliary seed metering cone, wherein the seed tube is connected with an external seed metering device and conveys seeds discharged out of the seed metering device; the auxiliary seed metering cone uniformly disperses seeds in the seed tube and used for improving the equalization probability when the seeds fall down from the seed tube; the protecting plates are used for preventing the seeds from leakage; the baseplate keeps a certain dip angle with the ground, so that the seeds can conveniently fall down along a seed metering ditch on the inclined baseplate; the separating plates are used for dividing the baseplate into a plurality of seed metering ditches and enabling the seeds to be discharged out of the seed metering ditches so as to increase the seeding uniformity. The semi-circular-ring-shaped structure is adopted for uniform distribution of falling seeds, the auxiliary seed metering cone enables the falling seeds to be uniformly distributed in the seed metering ditches, the necking seed metering ditches restrain the seed falling process, and the wheat wide-seed-strip planting uniform seeder is simple in integral structure, high in seeding quality, good in uniform distribution effect and convenient to refit.
Description
Technical field
The present invention relates to agricultural mechanical field, especially a kind of wheat wide seedling belt sowing Even seeding device, for being uniformly distributed between the wheat seeds after seeding in wheat wide seedling belt precision drilling operation.
Technical background
" wide seedling band precise sowing " technology is that state key promotes one of " cost-saving synergistic " agricultural modernization production technology, wide width precise sowing is compared with existing cropping pattern, wheat wide seedling belt precise sowing narrow drilling intensive for traditional seed is become the equally distributed wide cut grain of seed to broadcast, wheat single file sown scope is by traditional 2 ~ 3 centimetres, be widened to 8 ~ 10 centimetres, all seeds in wide seedling band all reach maximum spacing.Its advantage is to guarantee that wheat distributes in root uniform plane, decrease the contention of moisture between individuality, nutrient, be conducive to ventilation, printing opacity in wheat population, promote that ontogeny is healthy and strong, improve photosynthetic rate and water and fertilizer utilization, wheat mature spike number increases, and can obtain big panicle many grains per panicle, realize wheat increase yield and increase income.
Wheat seeder traditional at present uses the plough of boots shovel, arrow spade type or disc type to output kind of a ditch, and wheat seed is discharged to grain tube through seeding unit, is then dispensed onto into strips in kind of ditch by seed by grain tube.This traditional approach cannot form the required evenly seeding belt of " wheat wide seedling belt precision drilling " agronomy.Therefore, after ending kind of ditch, the even seeding belt of 8 ~ 10 centimetres can be completed to complete seed-distributing operation in the urgent need to a kind of high-efficiency precision amount seeder, to reduction wheat seeds input cost, boost productivity, realize wheat increase yield and increase income, there is important society and economic implications.
By finding the document retrieval of prior art, present seeder kind is few, function is few, efficiency is low, if Chinese invention patent " the Simple negative-pressure formula seeder " patent No. is 201320750199.0, structure is made up of sucker and extractor fan two parts, seeds sucker is surrounded by upper bottom surface, bottom surface and the sealing support edge between upper bottom surface on four edges, seeds sucker is made to become negative pressure cavity, this kind of mode power consumption is large, complex structure and being controlled seeding quantity, but the Even seeding of wide seedling band cannot be realized.Chinese invention patent " the two flap disc trench digging of wheat wide kind band divides kind of a device " patent No. is 201220566186.3, provide a kind of two flap and divide kind of a device, but being uniformly distributed of this structure seed planting position, uncontrollable whereabouts, does not therefore just reach the requirement of seed Even seeding yet
Summary of the invention
The present invention is directed to the defect of prior art, solve the problem of existing sower fabric lack of homogeneity, invented a kind of wheat wide seedling belt sowing Even seeding device, have that wide seedling band seed is evenly distributed, seeding quality is good, advantages of simple structure and simple.
The present invention adopts following technical scheme:
A kind of wheat wide seedling belt sowing Even seeding device, comprises grain tube, protective plate, demarcation strip, base plate and auxiliary seeding cone.Described grain tube is connected with outside dispenser, carries the seed of discharging from dispenser; Seed in grain tube leaves along the conical surface is dispersed, for improving the probability that seed is divided equally when grain tube falls by described auxiliary seeding cone; Described protective plate is used for preventing seed from leaking outside; Described base plate and ground keep certain inclination angle, are convenient to seed and fall along the seeding ditch on inclined floor; Described demarcation strip is used for base plate to be divided into multiple seeding ditch, and seed is discharged along seeding ditch, increases fabric uniformity.
The pipe that the pipe that described grain tube top is hollow, middle part are band scarf, bottom are semi-circular tube, grain tube top is connected with dispenser, grain tube bottom is provided with auxiliary seeding cone, and the seed that the scarf of grain tube inside makes dispenser discharge is semi circular surface distribution by the disc transition gradually that distributes, described protective plate is rectangular thin plate, and protective plate comprises back shroud and side protective plate, described side protective plate stops seed to leak outside on the one hand, is used for water furrow planting on the other hand, described auxiliary seeding cone is half-conical, its cone angle is between 50 ~ 80 °, auxiliary seeding cone stretches into grain tube inside, its upper end is concordant with the scarf lower surface of grain tube, the plane of auxiliary seeding cone plane side and grain tube lower semicircular pipe fits tightly, auxiliary radial distance between seeding cone and grain tube is within the scope of 0.5 ~ 1.5cm, adopt between the bottom surface semicircle of auxiliary seeding cone and base plate and be connected smoothly, seed is avoided to be slipped to by auxiliary seeding cone the phenomenon occurring collision reaction in base plate process, the planar side both sides of auxiliary seeding cone are fixed with back shroud, described base plate both sides are separately installed with side protective plate, base plate top is fixed with demarcation strip, need demarcation strip and side protective plate base plate to be divided into the seeding ditch of equidistant from distance according to fabric, seeding ditch adopts the dropping process of reducing type structural constraint seed, thus seed is evenly distributed on seedling band.
Present invention also offers the course of work of a kind of wheat wide seedling belt sowing Even seeding device, comprise the steps:
1) seed landing after the scarf of grain tube inside that dispenser is discharged is bored on the conical surface to auxiliary seeding;
2) seed makes it fall to base plate in the even slippage of all directions through the conical surface of auxiliary seeding cone;
3) through the seed of auxiliary seeding cone even drop down, continue to fall in the seed furrow of ground along the reducing type seeding ditch that inclined floor is separated, make fabric reach even density, effect that little line space is equal.
Beneficial effect of the present invention:
1, the present invention adopts semicircular ring structure to realize being uniformly distributed of whereabouts seed, the seed that auxiliary seeding wimble structure causes to fall and break can be evenly distributed in seeding ditch, further by the dropping process of reducing type seeding groove structure constraint seed, thus reach and be evenly distributed on the seedling band of 8 ~ 10cm.
2, structure of the present invention is simple, and top connects any dispenser by grain tube, and while not changing existing wheat seeder primary structure, increase seeder and can complete the sowing of wide seedling band, seeding quality is high, uniform effective, and repacking is convenient.
