Abstract
The utility model discloses an air suction precision seed discharger which comprises a seed chamber, a seed discharge disk and a shaft, a seed scraper is arranged on the seed chamber, a venting shaft is formed on the right end of the shaft, an annular venting passage is fixed at the right side of the seed discharge disk, the annular venting passage is communicated with the venting shaft, seed passages are evenly arranged at the inner side of an air suction disk, and a seed pushing plate is arranged on the seed chamber; the utility model solves the problems of existing seed discharger of unstable seed taking and uneven seed discharging and has the advantages of low technology requirement and low energy consumption.
Description
The utility model relates to the seeding unit of sower.
Seeding unit is one of main working parts of sower.The air-suction seeding unit main working parts be one vertically, have a seed plate of inhaling the hole.There is vacuum chamber at the dish back side, links to each other with the blower fan inlet scoop, makes vacuum chamber produce negative pressure.The front of dish is a seed chamber.During work, the seed plate rotation, inhale the hole and filling kind of district's absorbed seed, through the zigzag seed scraping device, wipe off and inhale unnecessary seed on the hole, make each inhale the hole and only keep one, seed produces vacuum chamber above plough, suction disappears, and seed drops to (agricultural production institutional (this second edition of the north) the agricultural P143-147 of publishing house of Dongbei Agricultural College) in kind of the ditch by deadweight.Chinese patent CN2322365Y disclosed " driven sucking precise dibber ", it comprises seeds sucker, and its characteristics are that a side of seeds sucker is provided with seed chamber, and seed chamber is a semicircle, and its upper side is thrown away seed inlet and is gone out kind of a mouth, and going out kind of a mouth place has the inoculation plate; Seeds sucker is peripheral a week to be provided with the program request mouth, on the seeds sucker wall suction hole is arranged, and the side is provided with the aspiration dish, and the aspiration road of semicircular arc is arranged on the aspiration dish.When their shortcoming is work, vacuum chamber (aspiration dish be buckled on the seed plate and form) is fixing, the seed plate rotation, because of the two contact area bigger, so their air-tightness in rotating relatively are relatively poor, get kind of a negative pressure instability, cause that the amount of getting kind is unstable, seeding is inhomogeneous, be difficult to keep the quality requirement of precision drilling, and energy consumption is more.
The purpose of this utility model be to solve existing driven sucking precise seeder because of vacuum chamber and seed plate contact area big in relative rotation poor air-tightness cause instability, the uneven problem of seeding kind measured of getting.
Because of aspiration dish of the present utility model is fixed on the seed plate, during work, seed chamber is fixed, and seed plate rotates with the aspiration dish.Like this, with regard to solved because of seed plate and aspiration dish contact area big in relative rotation poor air-tightness cause getting kind of an instability, the uneven problem of seeding.It is low to the utlity model has specification requirement, advantage of low energy consumption.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is the cutaway view of present embodiment.
Fig. 2 is the left view of the aspiration dish of present embodiment.
Fig. 3 is the right view of the seed chamber of present embodiment.
With reference to Fig. 1-3, present embodiment comprises seed chamber 6, seed plate 4 and axle 5, seed chamber is provided with seed scraping device 3, the right-hand member of axle is hollow formation ventilating shaft 8, seed plate right side fixed air sucker 7, aspiration dish inboard be provided with seed plate on suction hole 2 corresponding annular air channels 10, annular air channel communicates with above-mentioned ventilating shaft by air flue 9 radially, the uniform kind road 1 that is positioned at the annular air channel outside on the seeds sucker, kind of road for pipe and with radially form an angle, seed chamber is provided with arc ejector blade 1, and ejector blade is positioned at inhales the inboard, hole.
Also can establish a little compression ring on the above-mentioned seeds sucker, be used to link up ventilating shaft and radial hole.Seed chamber also can be established seeds protecting plate outward.Axle, ventilating shaft are provided with sealing ring.
Claims (3)
1, a kind of driven sucking precise seeder, comprise seed chamber, seed plate and axle, seed chamber is provided with seed scraping device, it is characterized in that the hollow formation ventilating shaft of a right-hand member, an aspiration dish is fixed on the seed plate right side, and aspiration dish inboard is provided with and the corresponding annular air channel of suction hole on the seed plate, annular air channel communicates with ventilating shaft by the radially air flue on the aspiration dish, the inboard uniform outer kind road of annular air channel that is positioned at of aspiration dish, seed chamber is provided with ejector blade, and ejector blade is positioned at the inboard, suction hole of seed plate.
2, seed plate as claimed in claim 1, it is characterized in that kind of road for the pipe and with radially form an angle.
3, seed plate as claimed in claim 2 is characterized in that ejector blade is an arc.
