Abstract
The utility model discloses a precision single peanut seed metering apparatus based on chain drive, belonging to a seed metering device of a seed sowing tool of agricultural machinery and a novel agricultural technology capable of implementing precision single peanut seed metering. The precision single peanut seed metering apparatus mainly comprises a seed box, a chain wheel, a chain with attachments, a shaft, a bearing, a seed metering plate with special holes, and a fixed plate. Asymmetric special holes in a seed sucking plate are inclined through movement of the seed sucking plate on the chain with the attachments from low to high, so that seeds fall in the special holes in a tangent manner under the action of gravity and a friction force, and low-position seed charging is realized; meanwhile, the width of an outlet of the seed box is limited to ensure that the seeds are charged in the special holes in a direction parallel with the special holes, and the vibration of the chain is combined, so that the single seed charging rate is increased; the chain is inclined and is combined with a special hole design, so that gravity seed clearing is favorably realized, a seed clearing device is omitted, the seed damage is reduced, and the seed charging rate is increased due to high-position seed charging. By changing the design of special holes and replacing a chain plate, the precision single peanut seed metering apparatus can adapt to precision single seed sowing of other seeds. The precision single peanut seed metering apparatus has the characteristics of simple structure, stable performance, reliability in working, high single seed rate, small seed damage, high adaptability, and the like.

Technical field:
The utility model belongs to the dispenser on agricultural mechanical seeders tool, can realize peanut essence amount monoseeding, belongs to agricultural machinery technological field.
Background technology:
Peanut is one of important economic crops of China, approximately 5,000,000 hectares of cultivated areas, and gross yield, 1,400 ten thousand tons of left and right, accounts for the more than 40% of Peanut gross yield, ranks first in the world, and meanwhile, China is also first country of consumption and the exported country of peanut.In recent years, due to the adjustment of pattern of farming, the popularization of new technology, China's peanut cultivation area constantly expands, and output increases year by year, improves energetically peanut cultivation machineryization necessary.
All the time, peanut adopts pair grain sowing of every cave, causes peanut sowing quantity larger, and the whole nation is about 1500kt for cooking the peanut of planting every year, accounts for 10% left and right of national gross yield.Carry out in recent years the research of peanut single grain fine sowing high-yield culturing philosophy and technique, can be in the situation that peanut sowing quantity reduce 1/3～1/4 compared with conventional cultivation, volume increase 3～5%.Change the success of the test that two grains are simple grain, become the production culture technique of a new cost-saving synergistic, synergy is remarkable.
In peanut single grain fine sowing high-yield culture technique, precision planter is the key that ensures single grain fine sowing, and precision seeder is the core component of precision planter.The problems such as traditional peanut hill-drop feed run is taking two bunch plantings as main, and seeding accuracy is 2/cave, and exists percentage of damage high (skin is thin easily to be fallen), and survival rate is low, especially for single grain fine sowing (1/cave), reduce percentage of damage and have prior meaning.For promoting this " cost-saving synergistic " agricultural modernization production technology technology of peanut single grain fine sowing, research and design single-grain precision seeding apparatus, improve peanut seed simple grain seed-filling rate, reduce percentage of damage, and the single grain fine sowing dispenser of simple in structure, stable performance, reliable operation is current peanut single grain fine sowing urgent problem, to increasing economic efficiency, reduce production costs, the development of accelerating peanut production mechanization has important practical significance.
Utility model content:
The purpose of this utility model is to provide a kind of based on chain-drive peanut single-grain precision seeding apparatus, this device can be realized the simple grain precise sowing of peanut, has that simple grain rate is high, simple in structure, a feature such as stable performance, reliable operation, seed damage are little, strong adaptability.
Comprise in order to reach the technical scheme that the purpose of this utility model takes: be arranged on kind case (7), driving shaft (1), driven shaft (3) on fixed head, drive sprocket (10), driven sprocket (9), band annex chain (8), bearing (2), seeding board (4), plants the members such as brush (11).
Above-mentioned based in chain-drive peanut single-grain precision seeding apparatus, drive sprocket (10), driven sprocket (9) are contained in respectively on the axle (1), axle (3) with difference in height; Two band annex chains (8) are contained in respectively on drive sprocket, driven sprocket, and by chain wheel drive; On be bolted seeding board (4), seeding board is duroplasts, easy to process, cost is low, its surface can adhere to elastomeric material to reduce the breakage of peanut seed; On each seeding board, have asymmetrical irregularly-shaped hole (6), on the chain tilting, the shape of irregularly-shaped hole is convenient to seed capsule under Action of Gravity Field and is entered type hole, and chain rotates and makes seeding board be convenient to charge seed down time in type hole, the size of irregularly-shaped hole (6) is relevant to peanut seed shape facility, distributes in carrier bar equal intervals.Vibration in chain drive process is conducive to the kind of filling of seed.
Above-mentioned based in chain-drive peanut single-grain precision seeding apparatus, on the each carrier bar on band annex chain (8) and every seeding board (6), all there is bolt hole (5), be bolted fixing seeding board, easy for installation, be convenient to change, change different structure type hole, can adapt to other seed.
Above-mentioned based in chain-drive peanut single-grain precision seeding apparatus, directly over seeding board, settle kind of a case (7), plant case and adopt the approximate design that is " S " type of unsymmetric structure to optimize the mobility status of seed in kind of case, and reduce the pressure of seed to chain; Plant case exit parallel with chain, its A/F restriction seed fills kind of an attitude, makes seed be parallel to the motion of irregularly-shaped hole direction and is convenient to single seeded filling.
Above-mentioned based in chain-drive peanut single-grain precision seeding apparatus, kind of brush (11) is contained on kind case (7) inwall close to driving wheel (10), in order to brush out seed unnecessary in type hole, and seed is lain low in irregularly-shaped hole, to reach the object of simple grain precision metering device.If chain inclination angle is enough large, inclination chain can be realized gravity seed cleaning, now can save cleaning device, has reduced the damage of seed.
