Description
Technical field
The utility model belongs to agricultural machinery, relates generally to the seeding parts on the seeding machinary.
Background technology
Along with the raising of Tendency of Agricultural Machinery in China level, large-scale dry farmland seeder tool is used widely aborning.For simplifying seeding unit seeding operation drive system structure, on large-scale seeding machinary, begin more employing air-suction seeding unit at present, and the gesture that substitutes the mechanical type seeding unit is gradually arranged.But, on existing air-suction seeding unit structural design, its overall arrangement is that kind of chamber is in the outside portion, induction chamber is in the inside portion, i.e. outside seed filling type aspiration seeding unit, and this class formation makes seeding unit appearance and size increase, volume is big, both be unfavorable for that configuration was installed on facility, increased facility weight again, and changed simultaneously and inhale seed plate inconvenience; In addition, the air-suction seeding unit of said structure is inhaled seed plate by being power transmission shaft, being that an axle of driving shaft drives again, and this driving shaft is low apart from ground level, is very easy to drag native phenomenon during seeding operation, result in blockage, reduce seeding operation quality and operating efficiency.
Summary of the invention
The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides seed filling type seeding unit in a kind of aspiration of new structure, reaches simplified structure, reduces overall dimensions, reduces weight, the convenient purpose of using, reducing the operation fault, improve operating efficiency of adjusting.
Basic design of the present utility model is, installation power transmission shaft that on the upper and lower of housing, is parallel to each other and suction feed shaft, install drive sprocket and drive sprocket respectively on power transmission shaft and suction feed shaft, chain is overlapped on drive sprocket and the drive sprocket, connects; Equipped negative inspiratory pressure assembly on the housing sidepiece, inhaling seed plate is packed on the suction kind shaft end, and between negative inspiratory pressure assembly and housing sidepiece, the negative inspiratory pressure chamber of negative inspiratory pressure assembly contacts with the lateral surface of inhaling seed plate and is sealed and matched, the medial surface of inhaling seed plate is positioned at and fills kind indoorly, so far constitutes seed filling type seeding unit in the aspiration.
The utility model has realized that air-suction seeding unit inhales that power transmission shaft and the driving of seed plate are set up separately, the outside is air-breathing, the filling seed inside structural design, has that new reasonable, the whole device overall volume of structural design is little, in light weight, the operation fault is few, operational benefit is high, change suction seed plate characteristics easily.

Embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Seed filling type seeding unit in a kind of aspiration, installation power transmission shaft 2 that on the upper and lower of housing 9, is parallel to each other and suction feed shaft 6, on the middle part of power transmission shaft 2 and suction feed shaft 6, install drive sprocket 1 and drive sprocket 7 respectively, chain 12 is overlapped on drive sprocket 1 and the drive sprocket 7, connects; The equipped negative inspiratory pressure assembly 5 of symmetry on housing 9 both sides, inhaling seed plate 8 symmetries is packed on suction feed shaft 6 both ends, and lay respectively between the negative inspiratory pressure assembly 5 and housing 9 sidepieces of both sides, the negative inspiratory pressure chamber 3 of negative inspiratory pressure assembly 5 contacts with the lateral surface of inhaling seed plate 8 and is sealed and matched, and the medial surface of inhaling seed plate 8 is positioned at and fills kind of chamber 10.Stirring wheel 4 is installed on the medial surface centre of inhaling seed plate 8, and these stirring wheel 4 integral body are positioned at fills kind of chamber 10.At equipped kind of the tongue 11 of scraping in kind of the chamber 10 that fills of housing 9, this is scraped kind of tongue 11 and cooperates with suction seed plate 8 medial surfaces.
During operation, power transmission shaft 2 rotates, through drive sprocket 1, chain 12, drive sprocket 7, inhaling feed shaft 6 driving suction seed plates 8 and stirring wheel 4 rotates in the lump, the kind grain that fills in kind of the chamber 10 of housing 9 successively splashes under stirring wheel 4 effects, the seed that will fill under 3 suction functions of the negative inspiratory pressure chamber of negative inspiratory pressure assembly 5 in kind of the chamber 10 is adsorbed on the kind hole of seed plate 8 medial surfaces, the suction seed plate 8 that is adsorbing seed on the medial surface rotates continuously, kind of grain 3 cooperates and to escort motion below housing 9 down in the negative inspiratory pressure chamber, when the position of inhaling seed plate 8 absorbed seeds cooperates with 3 disengagings of negative inspiratory pressure chamber, when promptly the kind grain goes to the outside, housing 9 bottoms, sow at the deadweight of kind of grain and centrifugal action and to broadcast in kind of the bed, finish aspiration, row's seeding operation.Scrape kind of tongue 11 and will inhale the unnecessary seed that adsorbs on seed plate 8 medial surfaces and fall clearly in filling the 10 kinds of grains in kind of chamber, the purpose and the effect of reach precision drilling, saving seed.
