Description

A kind of centralized pneumatic precision seed-metering device
Technical field
The present invention relates to seeding technical field in the agricultural machinery, be specifically related to a kind of centralized pneumatic precision seed-metering device, emphasis is the essence amount seeding problem that solves crop seed, applicable to the essence amount seeding of seeds such as rape seed, test tube seed potato, mung bean, soybean, corn, wheat.
Background technology
General seeding unit comprises mechanical type and pneumatic type two classes both at home and abroad.The mechanical type seeding unit mainly is applicable to the sowing of big-and-middle particle diameter seeds such as soybean, corn, wheat at present, and there are problems such as seeding accuracy difference in the sowing that is used for the small particle diameter seed.Precision and stability as mechanical type rape seed seeding unit are all poor, and particularly breakage and the blockage problem of rape seed in seeding unit is to hinder the technical bottleneck of mechanical type rape seed seeding unit large-scale application always; And for example, mechanical type potato seeding unit can be realized the sowing of potato, but the damage problem of bud base in seeding unit in precision and poor stability, the especially potato seed is the bottleneck that hinders mechanical type potato seeding unit large-scale application always.
Compare with the mechanical type seeding technique, the pneumatic type sowing seeds technology has, complete machine versatility good, operating speed advantages of higher tight to the requirement of seed appearance and size, becomes the main developing direction that sowing seeds technology and equipment are developed.The pneumatic type sowing seeds technology can guarantee that in theory the seed breakage rate is lower than the mechanical type precise seeder, makes its seed-metering performance be better than the mechanical type precision drilling.But the most complex structure of pneumatic type seeding unit involves great expense; And, in the at present general all kinds seeding unit, no matter be mechanical type or pneumatic type, a general seeding unit only is responsible for sowing delegation, in order to realize the operation of high efficiency multirow wide cut, on the sower a plurality of seeding unit monomers must be installed, both increase machine quality and manufacturing cost, and caused implement structure complexity, power consumption height, I﹠M inconvenience, reliability decrease.Therefore, researching and developing a kind of efficient, energy-conservation, compact conformation, installation and pneumatic type easy to use, succinct practicality concentrates seeding unit to have important practice value.
Summary of the invention
Defective such as the objective of the invention is to overcome existing seeding unit complex structure, the complete machine quality is big, power consumption is high, I﹠M is inconvenient and involve great expense, provide a kind of simple and compact for structure, low in energy consumption, quality is little, and seeding accuracy height, the centralized precise seeder of potato strength that seeding quality is good.The present invention adopts the main body of cylinder as seeding unit, multirow is installed on cylinder is inhaled kind of a tube (inhale kind of the line number of tube and determine according to producing actual needs, this explanation is an example to sow 6 row rape seed), places negative pressure distributing pipe in the cylinder; Negative-pressure air fan provides negative pressure for seeding unit, and distributing pipe is evenly assigned to each with negative pressure and inhaled kind of a tube, and suction kind of a tube forwards seed-box to and fills kind of district's absorption single seed, and seed falls into sowing port in the effect of scraping kind of offset plate when forwarding the seeding district to, finishes seeding; The present invention uses a seeding unit, realizes the multirow seeding of seed, can simplify the seeding process, improves the seeding quality, has the sower of alleviating quality, reduces advantage such as sower manufacturing cost significantly.
The present invention realizes by following technical proposal:
A kind of centralized pneumatic precision seed-metering device, it comprises sowing port (1), seed-box (3), cover plate combination (4) and drive sprocket (8), and it also comprises cylinder combination (6), retaining kind of combination (7), scrapes kind of combination (2) and a cylinder sealing device (5).Described cylinder combination (6) is made of left spindle nose (24), suction kind of tube (25), a negative pressure distributing pipe (26), cylinder (27) and right spindle nose (28).Wherein, left and right sides spindle nose (24,28) and cylinder (27) welding are inhaled kind of a tube (25) and are welded on the cylinder (27), and air inlet (22) is connected with negative pressure distributing pipe (26) interference, and cylinder combination (6) is installed in the middle of the seed-box (3); Retaining kind of a combination (7) comprises connecting plate (29), fixed head (30) and offset plate (31), and fixed head (30) is welded as a whole with connecting plate (29), and connecting plate (29) is fixed on seed-box (3) below; Cylinder sealing device (5) is made of air inlet (22), sealing ring (23), is installed on cylinder combination (5) left end; Cover plate combination (4) comprises cover plate side plate (17), rotating shaft (18), sleeve (19), split pin (20) and upper cover plate (21), and cover plate combination (4) is installed in the seed-box top; Sowing port (1) is made up of seeding sidewall 1 (9), seeding sidewall 2 (10), seeding sidewall 3 (11) and kind separator for container (12), sowing port (1) below with lead kind of a mouth (13) and be connected, lead kind of a mouth (13) and go out kind of a mouth (14) and link to each other, go out kind of mouth and can connect grain conductor, sowing port (1) is positioned at scrapes kind of combination (a 2) the place ahead;
The invention has the beneficial effects as follows:
1, the pneumatic type seeding can realize the simple grain precision drilling, and the damage of kind of bud is reduced, and saves seed, improves the seed availability, can significantly reduce field management work such as follow-up thinning, final singling.
2, simplify the seeding process, with the filling kind of general pneumatic type seeding unit, inhale plant, plant clearly, protect kind, many processes such as seeding are reduced to kind, seeding two processes of inhaling, and have strengthened the controllability in the seeding process, can significantly improve the seeding quality.
3, compare with general seeding unit, the present invention has replaced a plurality of seeding unit monomers with a concentrated seeding unit, has alleviated the sower quality, has simplified the sower structure, is convenient to Installation and Debugging and maintenance, has saved manufacturing cost, and the use that helps sower is promoted.
