Description
Technical field
the utility model relates to field of agricultural machinery, particularly a kind of air-suction seeding unit.
Background technology
Sower is the class planting machinery for crops seeding, is the main facility of farmland operation, plays an important role in agricultural production.Seeding unit is as the critical component of sower, and its service behaviour directly affects the operation quality of whole sower.
At present, seeding unit mainly contains mechanical seed sowing device and Pneumatic seeding apparatus, and air-suction seeding unit is as the seeding method the most ripe in current known seeding technique, precision is the highest, is more and more subject to the attention of sead feeder manufacturer.Negative pressure is produced by high-speed fan during air-suction seeding unit work, pass to the vacuum chamber of seeding unit, during seed plate revolution, absorbed seed under vacuum chamber suction function, and rotate with seed plate, after seed produces vacuum chamber, no longer bear negative pressure, just by conducting oneself with dignity or dropping in ditch under seed scraping device effect.Traditional air-suction seeding unit comprises a seed plate usually, and realize " single ditch single line " seeding, namely a line seed broadcast by a seeding unit, and sowing efficiency is low.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of air-suction seeding unit, improves sowing efficiency.
For solving the problems of the technologies described above, technical scheme provided by the utility model is: a kind of air-suction seeding unit, comprise seeding body, seed plate and seed cabin, the vacuum chamber and antivacuum room that mutually cut off is provided with in described seeding body, described vacuum chamber is connected with air holes, described antivacuum room is connected with sowing opening, in the axial center hole of described seeding body, bearing is installed, in described bearing, feed shaft is installed, it is external that described seeding unit is all stretched out at the two ends of described feed shaft, described seed plate is positioned at the side of described seeding body, be rotatably connected on described feed shaft, and described seed plate is provided with circumferentially equally distributed groove and sucker, wherein, described feed shaft there is the seeding body that two symmetrical, described seed cabin is between described two seed plates.
Preferably, in above-mentioned air-suction seeding unit, also comprise and to stir kind dish, described in stir the side that kind of dish is positioned at described seed plate, be rotatably mounted on described feed shaft.
The beneficial effects of the utility model are: a kind of air-suction seeding unit, comprise seeding body, seed plate and seed cabin, the vacuum chamber and antivacuum room that mutually cut off is provided with in described seeding body, described vacuum chamber is connected with air holes, described antivacuum room is connected with sowing opening, in the axial center hole of described seeding body, bearing is installed, in described bearing, feed shaft is installed, it is external that described seeding unit is all stretched out at the two ends of described feed shaft, described seed plate is positioned at the side of described seeding body, be rotatably connected on described feed shaft, and described seed plate is provided with circumferentially equally distributed groove and sucker, described feed shaft there is the seeding body that two symmetrical, described seed cabin is between described two seed plates.Negative pressure is produced by high-speed fan during air-suction seeding unit work, pass to the vacuum chamber of seeding unit, during seed plate revolution, absorbed seed under vacuum chamber suction function, and rotate with seed plate, after seed produces vacuum chamber, no longer bear negative pressure, just by conducting oneself with dignity or dropping in ditch under seed scraping device effect.The air-suction seeding unit that the utility model provides is containing two seed plates, and during seeding unit work, two seed plates operate simultaneously, once sow and broadcast two row seeds simultaneously, realize " single ditch two-wire " seeding, improves sowing efficiency.

Embodiment
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the utility model.On the contrary, they only with as in appended claims describe in detail, the example of device that aspects more of the present utility model are consistent.
A kind of air-suction seeding unit, comprise seeding body 1, seed plate 2 and seed cabin 3, the vacuum chamber A and antivacuum room B that mutually cut off is provided with in described seeding body 1, described vacuum chamber A is connected with air holes C, described antivacuum room B is connected with sowing opening D, in the axial center hole of described seeding body 1, bearing 6 is installed, in described bearing 6, feed shaft 7 is installed, the two ends of described feed shaft 7 are all stretched out outside described seeding body 1, described seed plate 2 is positioned at the side of described seeding body 1, be rotatably connected on described feed shaft 7, and described seed plate 2 is provided with circumferentially equally distributed groove 4 and sucker 5, wherein, described feed shaft there is the seeding body that two symmetrical, described seed cabin 3 is between described two seed plates 2.
During air-suction seeding unit work, seed cabin 3 includes a large amount of seed E, air holes C is connected with high-speed fan, feed shaft 7 is connected with motor, high-speed fan work produces negative pressure, pass to the vacuum chamber A of seeding unit, machine operation drives feed shaft 7 thus drives seed plate 2 to rotate, owing to seed plate 2 being circumferentially uniformly distributed the sucker 5 of fluted 4 and communication groove 4 and vacuum chamber, therefore, when seed plate 2 rotates, the seed E in groove 4 absorbed seed storehouse 3 is made under the suction function of vacuum chamber A, and seed E is rotated with seed plate 2, when seed E produces vacuum chamber A with seed plate, when forwarding antivacuum room B to, no longer bear negative pressure, seed E in groove 4 is fallen in the ditch on ground by the sowing opening D be communicated with antivacuum room under the effect of deadweight.In the present embodiment, the number of seed plate 2 is two, and during seeding unit work, two seed plates 2 operate simultaneously, once sow and broadcast two row seeds simultaneously, realize " single ditch two-wire " seeding.
In the present embodiment, air-suction seeding unit comprises and to stir kind dish 8, described in stir the side that kind of dish 8 is positioned at described seed plate 2, be rotatably mounted on described feed shaft 7.
During seeding unit work, stir kind of dish 8 under the drive of feed shaft 7, and seed plate 2 rotates simultaneously, stirs the seed in seed cabin 3, facilitates the groove 4 absorbed seed E under suction function on seed plate 2.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any make within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
