Description

Annular ring type Precision Seeding feed mechanism for seed

Technical field

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

Background technology

The cereal in China, millet is referred to as, 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 special product below.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 of grain paddy is produced, is that the Western Han Dynastry searches grain Zhao Duwei and crosses invention cocurrent An animal-drawn seed plough, drill and the stone for reaching the present ram the loose soil with a stone-roller after sowing.Modern mechanical, be imitate American-European external recessing seeder, though effect, uniformly Degree, controlled quentity controlled variable are much improved, but its quality standard, still drilling.Tradition is particular about " one mu of two conjunction（Sound lattice, one it is ancient rise ten/ One, refer to smart amount degree）", old farmer's wushu, sowed with a drill using an animal-drawn seed plough, can also reached, 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 cause 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 machine Tool does not catch up with, and resources advantage can not become economic advantages always.And the corn of crop is substituted, lack ternational grain market competition Power, country is turned into and has adjusted production object.So-called " the changing control " given ample rewards to is obtained, is the helpless of breeding man, 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, come from peasant, seedling rice transplanting, barefoot mire mud, curved work hardships.Though the modern times have Rice transplanter is invented, but is still limited to peasant's thinking.

Precision Seeding feed mechanism for seed, design department row precision seeder, supporting various driving forces are researched and developed, and are reformed by agronomy, are one, are realized 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 that instead of craft, the seed that will gather in reservoir, according to the cave grain of seeding operation requirement Number, cave spacing in the rows etc., go-no-go go out a group amount（Containing simple grain）Seed, be discharged to underground seed ditch.Thus, it is referred to as the heart of seeder It is dirty, and decide the technical level and economic benefit of seeder.

Classical cell-seed distributor, structure pass through the overcoat on its overcoat 32 as shown in figure 1, seed 121 is contained in kind bucket 1 Input hole 33, fallen into by deadweight in the pocket 36 on beaming roller 35, when its beaming roller 35 rotates, its pocket 36, i.e., with falling into wherein Seed 121, leave overcoat input hole 33, rotate 180 degree, go to overcoat delivery outlet 34 and discharge.Its pocket 36 is with falling into it In seed 121, when leaving overcoat 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 " essence of a letter two ".But its exist pressure scrape kind caused by seed shearing it is broken Broken problem.It scrapes kind, i.e., seed unnecessary in pocket is removed, rotated with to ensure beaming roller in overcoat it is without hindrance, with being planted in pocket 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 pocket, Second half projection the rear wall of pocket, when promoting the seed to input hole antetheca, that is, is stuck outside pocket, produces shearing, causes It is broken, or de- chaff is into rice, can not rudiment, instead into load.Thus, the feed mechanism for seed, 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, based on foregoing classical cell-seed distributor, as shown in Fig. 2 removing on overcoat 32, contains Beaming roller 35 and pocket 36, the whole construction of side, and in the former antetheca position of overcoat input hole 33, hairbrush 37 is installed, makes its structure The soft sky of scraping of paired seed 121 is sent, and overcomes the shearing-crushing of seed 121.But Crushing Problem solves, seed number per and cave strain Away from it is accurate the advantages of but lose.Reason is, one, hairbrush frequently rub, loss deformation, scraping force is lost permanent, takes kind out of control.2nd, Seed dials in pocket in the case where hairbrush suppresses, with different conditions, and the wedge different from the generation of pocket wall is puted forth effort, when the seed of discharge produces Between it is poor.3rd, pocket beaming roller operates, velocity variations, and seed produces different centrifugal force, under the constraint for losing overcoat, forms nothing Sequence is shed.4th, 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 seeder 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.Turn and reverse end for end, suction deficiency, sky is broadcast seriously.Duckbilled drum-type seeder.Duckbilled punches, Intercutted on sharp film.Roller lands, sharp cave strain spacing.But the built-in feed mechanism for seed, also it is not up to " essence zero of a letter two is broken ".

Correlation, traditional an animal-drawn seed plough are sowed with a drill, so that modern precision seeder, its 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 rod of wearing cloth shoes with the backs turned in addition, clod dry ground is scraped into ridge eye together, extensive Multiple soil moisture content, delays time.Its land presser, stone roller, restricted building stones prejudice, take circle drum profile.Pressure is good, but ridge is now It is recessed, rain, water product ridge eye, seedling top plate knot, can not be unearthed, Gu Miao can be enclosed extremely, manually be abolished after broadcasting.

The content of the invention

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

The present invention adopts the following technical scheme that realization：
