According to the multifunctional accurate seed metering device, seeds in the seed box enter a seed filling region in the inner cavity of the regulation ring through the seed inlet, the inner cavities of the seed taking pipes are fully filled with the seeds after the seed taking pipes rotate to the seed filling region to perform seed taking, and the seeds fall into the seed discharging pipe so as to be discharged when the seed taking pipes rotate to the top of the seed taking disc. The multifunctional accurate seed metering device has the advantages that seed scraping hairbrushes or other seed scraping sheets are not used, the seeds are uniformly metered and are not damaged, the seeding quantity per acre is conveniently regulated, the seeds are easily cleared, the universality is good, the working process is reliable, and the structure is simple.
Description
Technical field
The utility model relates to agricultural machinery, particularly, is a kind of seed dropping mechanism that is mainly used in the various crop such as seeding corn, soya bean, mung bean, Chinese sorghum.
Background technology
Sower is the key equipment of whole entire mechanization system, the development of flow chart and other facility after the quality of seeding quality directly affects.Seeding unit is the core component of sower, and current seeding unit type has: Traditional Wood an animal-drawn seed plough, outer groove wheel, indent type, push away by force kind of a formula, oscillatory type, duck-beak type, paper tape formula, belt-type, sponge formula etc.These seeding units have the basic functions such as the filling kind, plant clearly, protect kind of general seeding unit, seeding.But all there is different defects and can not meet preferably planting requirement, for example, plant clearly hairbrush quick abrasion, the evenly poor difficult adjusting of each row, the coefficient of variation is large, and percentage of damage is high; Complex structure, is difficult for renewal part; Mechanism is heavy, gets kind of an inaccuracy, and manufacturing cost is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of multi-functional accurate seed dropping mechanism, and this device has seeding and evenly, do not damage seed, regulates the mu amount of broadcasting feature convenient, that easily plant clearly.
For solving above technical problem, the technical solution adopted in the utility model is:
A multi-functional accurate seed dropping mechanism, comprises kind of a case, adjustable ring, seed taking disc, gets kind of a pipe, seed plate, discharging tube, axle and bearing; Adjustable ring is hollow circular cylinder, and middle part, side has axis hole, and bottom has plants clearly mouth, and lower side has seed inlet, plants case bottom and is communicated with this seed inlet; Seed plate is the hollow cylinder with annular wing plate, and wing plate and adjustable ring are fixed, and top, the face of cylinder has feed outlet, and discharging tube is connected in feed outlet; In adjustable ring, be provided with seed taking disc, on seed taking disc, be evenly equipped with and get kind of a pipe; Get the hollow column that kind of pipe is both ends open, get kind of a tube column surface and have and get kind of a mouth, bottom support is on the face of cylinder of seed plate; The center of axle front end and seed taking disc is fixed.
By external drive unit by transmission of power to axle, axle drives kind of the pipe of getting on connected seed taking disc and seed taking disc to rotate, the seed of planting in case flows into adjustable ring inner chamber Chong Zhong district from seed inlet, turning to getting after kind of pipe is got kind by Qu Zhong Kou Chongzhong district of Chong Zhong district fills up and gets kind of a tube cavity, seed unnecessary in Chong Zhong district is removed from clear kind mouthful automatically by Action of Gravity Field, when getting kind of a pipe and turning to seed plate top, seed falls in discharging tube and discharges from feed outlet, energy over-rotation adjustable ring can change the position of the seed inlet of side, thereby can change the quantity that enters Chong Zhong district seed.
As a kind of preferred technical scheme, the wing plate of adjustable ring and seed plate is fixed by clamping screw, and rotational lock bolt withstands seed plate by screw tip, gets final product secured adjusted ring, contributes to rotating adjustment ring.
As a kind of preferred technical scheme, get kind a pipe top adjusting bolt be housed, by rotation adjusting bolt, can change the volume of getting kind of tube cavity, change enter get kind of pipe seed number, thereby can conveniently regulate the mu amount of broadcasting.
As a kind of preferred technical scheme, adjustable ring is equipped with lucite on the sidewall of seed taking disc one side, can help operating personnel to observe seeding unit inside and fill the duties such as kind of amount.
The multi-functional accurate seed dropping mechanism that the utility model provides, does not need to scrape kind of hairbrush or other and scrapes that kind of a sheet, seeding evenly, do not damage seed, regulate the mu amount of broadcasting conveniently, easily clear to plant, versatility is good, reliable operation, simple in structure.
