Description
Affiliated technical field
The utility model belongs to the air-flowing type precise rape seeding device of the sower seeding unit, particularly a kind of Photoelectric Detection of agricultural machinery.
Background technology
China is rape producing country the biggest in the world, and the rapeseed cultivation area has been broken through 8,000,000 hectares at present, about 1,200 ten thousand tons of gross annual output amount, and cultivated area and yield of rape account for 1/3 of the world, occupy first place in the world.The rape production process and the state of the art of current China, main manual work and the mechanical work dual mode of adopting, because of still planless, the perfect machine coordination of mechanical work, still producing the needs that all lag far behind production operation in the development, not only labour intensity is big, and inefficiency, operation quality can not be guaranteed, and has seriously restricted the paces that China's rapeseed cultivation already develops.Development rape production is badly in need of realizing mechanization, and it be planting link that rape is produced one of key technology of entire mechanization, and mechanical live be the developing direction of rapeseed cultivation mechanization.
Precise seeder is one of core component of mechanical live facility, it is used for precise hole sowing or the simple grain precise spot-sowing of crop, seeding unit is discharged several seed cluster ground at interval during the precise hole sowing operation, and during the simple grain precise sowing, then carries out single seeded discharging by certain time interval.Precise seeder can be divided into two big classes by its seeding principle that adopts, and a class is the mechanical type precise seeder, seed is separated from kind of case with the type hole of seeding unit according to the seed grain type, fills kind, plants clearly and seeding is finished by the deadweight or the mechanical device of seed; Another kind of is the pneumatic type precise seeder; drive blower fan by tractor dynamic power output; produce pull of vacuum or air pressure, make seed be attached to and finish kind of the process of filling on the type hole, clear plant and seeding leans on the deadweight or the mechanical device of seed to finish by grain (simple grain or many).At present the form of the mechanical type precise seeder that uses aborning have that horizontal circle disc type, nest eye are wheeled, spoon disc type, pore area formula etc., the pneumatic type precise seeder comprises air-sucking type, air-sweeping type and vapour-pressure type etc.Horizontal circle disc type seeding unit is relatively poor to the adaptability of sowing at a high speed, and is very tight to the specification requirement of seed; In nest eye Type Seed Metering Device when work,, seed is to rely on gravity to roll in the type hole, relies on gravity fall again, and the deadweight of seed is had certain requirement; Spoon disc type seeding unit be applicable to big seed () sowing of grain seed, and monoseeding operation instability; Pore area formula seeding unit complex structure, volume are big, the sowing of incompatibility fine grain seed; Because rape belongs to the fine grain seed, single seed is in light weight and seeding quantity is little, uses the mechanical type precise seeder, and the precision of sowing is difficult to control.Air-suction seeding unit is to rely on air pressure that seed is evenly distributed on hole roller or the cylinder to finish seeding operation, has operation quality height, Seeding Uniformity is good, the seed percentage of damage is low characteristics, is applicable to the high speed operation; Air-sweeping type seeding unit and vapour-pressure type seeding unit, with seed by steady air current on hole roller, fall by the deadweight of seed then; The pneumatic type precise seeder is mainly used in the precision drilling of big seed seed such as soybean, corn, cotton, can't guarantee the seeding accuracy and the operation quality of fine grain rape seed.Therefore, the characteristics of comprehensive various precise seeders and operation principle are developed the precise rape seeding device that a kind of operation quality is good, seeding accuracy is high and operating efficiency is high, are of great immediate significance for the development of China rapeseed cultivation industry industrialization.
