Description

Annular ring type Precision Seeding feed mechanism for seed

Technical field

The present invention relates to the feed mechanism for seeds of agricultural mechanical seeders, especially being capable of precise spot-sowing China the South and the North main file grain Oil: the feed mechanism for seed of grain paddy, paddy and five wheats, eight beans etc..

Background technique

The cereal in China is referred to as millet, and the north is the grain of millet, and south is the rice of rice.

Millet, millet, grain, nominal grain paddy, is northern China time immemorial specialty below.It is water-saving, nutrition, high added value, therefore be It is staple food grain, imperial-cereals, soldier's pay and provisions, currency first of nine paddy.The ancient machinery for producing grain paddy is that the Western Han Dynastry searches grain Zhao Duwei and crosses invention cocurrent Modern an animal-drawn seed plough, drill and stone is reached to ram the loose soil with a stone-roller after sowing.Modern mechanical is the seeder of imitative American-European external recessing, though effect, uniformly Degree, control amount are much improved, but its quality standard, still drilling.Tradition be particular about " one mu two close (sound lattice, ancient ten risen / One, refer to smart amount degree) ", old farmer's wushu is sowed with a drill using an animal-drawn seed plough, can also be reached, and an animal-drawn seed plough is sowed with a drill so continuing into the present.Bottleneck system existing for drilling About, that is, catch full stand, excess planting to rob season, and lead to artificial thinning final singling, time-consuming, hard work is made in crouching.So paddy The atrophy always of field area, staple food grain become small coarse cereals.China is small coarse cereals kingdom, 22 kinds of small coarse cereals that the Ministry of Agriculture arranges, because of machine Tool is not caught up with, and resources advantage becomes always not at economic advantages.And the corn of crop is substituted, lack ternational grain market competition Power has become country and has adjusted production object.So-called " the changing control " given ample rewards to is obtained, is the helpless of breeder, not " fundamental solution ".

Rice, millet, rice, nominal paddy, is south China and northeast time immemorial crop below.Production rice field area, diversion irrigation, Intensive cultivation, it is well-known.But traditional mode of production mode is derived from peasant, seedling rice transplanting, barefoot mire mud, curved work hardships.Though the modern times have Rice transplanter invention, but still it is limited to peasant's thinking.

Precision Seeding feed mechanism for seed, design department column precision seeder, mating various driving forces are researched and developed, and are reformed by agronomy, is one, realizes The successful approach of grain paddy very not thinning, is two, instead of artificial and machine rice transplantation, liberates the dominant direction of its productivity.

The feed mechanism for seed of seeder is to replace by hand, the seed that will gather in reservoir, the cave grain required according to seeding operation Number, cave spacing in the rows etc., go-no-go go out the seed of group amount (containing simple grain), are discharged to underground seed ditch.It is referred to as the heart of seeder as a result, It is dirty, and decide the technical level and economic benefit of seeder.

Classical cell-seed distributor, structure pass through the housing on its housing 32 as shown in Figure 1, seed 121 is contained in kind bucket 1 Input hole 33 is fallen into the indent 36 on beaming roller 35 by self weight, when beaming roller 35 rotates, indent 36, i.e., with falling into wherein Seed 121, leave housing input hole 33, rotate 180 degree, go to the discharge of housing delivery outlet 34.Its indent 36 is with falling into it In seed 121, when leaving housing input hole 33, pressure scrape kind, shearing-crushing.Although classical cell-seed distributor structure letter Single, seed number per is accurate, and cave spacing in the rows is accurate, is spoken approvingly of with " two essence of a letter ".But it is broken in the presence of seed shearing caused by forcing to scrape kind Broken problem.It scrapes kind, i.e., seed extra in indent is removed, and is rotated with to guarantee beaming roller in housing without hindrance, and plants in indent The seed number per requirement of son.Problem is that seed is not spherial body, is not equally big.When the half of Some seeds is fallen into indent, Outside indent, the rear wall of indent is stuck the other half protrusion when pushing the seed to input hole antetheca, generates and shears, causes Broken or de- chaff at rice, can not rudiment, instead at load.The feed mechanism for seed as a result, extensive program request can be with, and seed is broken to make fertilizer, But the precise spot-sowing for precious seed is just dying.Seeder becomes rice mill, " one is broken " rejection.

Make a variation cell-seed distributor, is contained based on aforementioned classical cell-seed distributor as shown in Fig. 2, removing on housing 32 The entire construction of beaming roller 35 and indent 36, side, and in former 33 antetheca position of housing input hole, hairbrush 37 is installed, its structure is made The soft sky of scraping of pairs of seed 121 is sent, and overcomes the shearing-crushing of seed 121.However Crushing Problem solves, seed number per and cave strain It is but lost away from accurate advantage.The reason is that, one, hairbrush frequently rubs, loss deformation, scraping force loses perseverance, takes kind out of control.Two, Seed dials in indent in the case where hairbrush suppresses, with different conditions, generates different wedges from indent wall and puts forth effort, when the seed of discharge generates Between it is poor.Three, indent beaming roller operates, and velocity variations, seed generates different centrifugal force, under the constraint for losing housing, forms nothing Sequence is shed.Four, the north is sowed in spring, and travel fatigue diffuses, and exposure seeding, seed scrapes unrest.

Information age, take an overall view of network, variation cell-seed distributor is in cereal, millet so that use part in the precision seeders such as vegetables Volume accounts in eight or nine cases out of ten.Problem: seeding is overstocked to cry replay, excessively dilute to cry broadcast leakage, can all influence yield per unit area.

It is forefathers to cell-seed distributor in addition, air-suction type accurate sower, damaged helpless of seed has walked complication Route.Negative pressure is airtight, increases cost on foot.Turning u-turn, suction is insufficient, and sky is broadcast seriously.Duckbilled drum-type seeder.Duckbilled punching, It is intercutted on sharp film.Roller landing, sharp cave strain spacing.But the built-in feed mechanism for seed is also not up to " two essence zero of a letter is broken ".

Correlation, traditional an animal-drawn seed plough are sowed with a drill, so that modern precision seeder, plough, an animal-drawn seed plough ploughshare continue shovel formula more.Penetration performance is good, but Trench digging cross section is V-arrangement, and seed landing is uneven, connects that moisture in the soil is poor, and the earthing such as stick of wearing cloth shoes with the backs turned in addition, clod dry ground is scraped together into ridge eye, extensive Multiple soil moisture content, delays time.Its land presser, stone roller, restricted building stones prejudice take circle drum shape.Pressure is good, but ridge is now It is recessed, it rains after broadcasting, water product ridge eye, seedling top plate knot can not be unearthed, and Gu Miao can be enclosed extremely, manually be abolished.

Summary of the invention

The present invention is broken in order to overcome the seed of classical cell-seed distributor, variation cell-seed distributor seed number per, cave strain Away from accurately technical problem is lost, the annular ring type Precision Seeding feed mechanism for seed of a kind of " two essence zero of a letter is damaged " is provided.

The present invention is achieved by the following technical scheme:

A kind of annular ring type Precision Seeding feed mechanism for seed, including vertical disk discharge plate；The seeding disk center is equipped with bottom water flat raft together Kind axis；In the feed shaft, lateral inclination runs through a delivery outlet；The upper port of the delivery outlet, positioned at the top surface of feed shaft；Institute It states outside feed shaft circumference, is cased with type hole ring；On the type hole ring, uniformly distributed type hole column；The seeding axial end, extension axle journal head, Axle bolt；The seeding lid, stem knob is welded in inside, with the around-France flange aperture grafting of type hole；The seeding lid, the quiet dress sprocket wheel in outside Set；The seeding lid presss from both sides control by the flange nut of axle bolt, dynamic to be coupled on axle journal head, covers discharge plate and seeding Axial end should rotate flexibly, tight-closed again, be allowed to not leak seed；The discharge plate, by its center line, the row of being welded in On the center line of kind pipe lateral incision；In the discharging tube lateral incision, interior weldering tilts spacing sheet, and discharging tube is divided into two pipe up and down Chamber；The discharge plate, bottom surface annular groove left side are provided with input hole；The input hole passes through seed guiding groove after disk and discharging tube upper tube Chamber connection；The lower port of the delivery outlet is connected to lumen under discharging tube after disk.

The type hole ring of the annular ring type Precision Seeding feed mechanism for seed, be from beaming roller, the indent differentiation of existing classical cell-seed distributor and Come.Discharge plate, seeding lid, annular groove are that the housing of existing classical cell-seed distributor is expanded sky.Delivery outlet is then solely to ward off Odd diameter, the key of inventive point.Input hole demotion leaves its point of kind path for.

When work, lumen into discharge plate, inputs seed through seed guiding groove, discharge plate input hole on discharging tube after disk Below hole, i.e., at 6-9 point of annular groove, forms dynamic and fill kind of an angle, flour heap dissipates angle principle, digs one and points out a bit, profit and loss are flat Weighing apparatus.The chain wheel case of power drive seeding outer side of lid rotates clockwise, and type hole ring is rotated around feed shaft.Seed is filling kind as a result, Entered angle-style hole in angle to scoop out.When the type hole for scooping out seed goes at 9-10, center of gravity does not enter the seed of type hole, then can be certainly Row, which falls, recharges kind of an angle, to complete the separation of extra seed.The type hole after separation of extra seed goes to feed shaft upper surface When at 12 points, i.e., seed is sent into delivery outlet, seed falls, lumen under discharging tube is returned after placing, so that the kind that plough is outputed Cunette.

The discharge plate inner bottom surface input hole upper end, is equipped with a scale plate by pressing plate bolt；The scale plate is to input Upper limb height in hole is adjusted, and kind of an angle height is filled in change, can relative changes type hole take kind of an angle.If wooden dipper bails, it is flat scoop it is then more, tiltedly It scooping and then lacks, side scoops hanging point, thus form the variable that type hole takes kind, i.e. the fine tuning of seed number per.

The present invention changes classical cell-seed distributor, and former end level on the circumferential surface takes kind, and the method for forcing to scrape kind is Periphery side takes kind, point kind, periphery upper end seeding form.The separation of its seed, completely by self weight, rather than forces external force, institute With absolutely not damaged.

The present invention, seed are scooped out under loose state, in constrained output duct under longitudinally perpendicular row, because forming Cave property, cave spacing in the rows precision are guaranteed.

The present invention, due to taking above-mentioned measure, Precision Seeding grain paddy, paddy, five wheats, eight beans have surmounted national ministry standard more Specification, and can realize that " paddy vegetable cigarette medicinal herbs " are multi-functional, " drag and help micro- poultry people " is complete mating.
