Portion is the lower kinds of bank deposits room 25;The right side of the lower kinds of bank deposits room 25 closely roads Hui Zhong 24;24 upper end of the roads Hui Zhong is cut by baffle 21
Only, middle and upper part bridges back kind of a bridge 23;Bridge opening is formed between described go back to 23 bottom surface of kind bridge and discharge plate allows seed to pass through;The slideway
One 22 left sides connect with kind of a bridge 23 is returned, and right side connects with the slideway 2 27 obliquely;Upper end and 24 upper end opening of the roads Hui Zhong
Connect;Kinds of bank deposits room 26 is closely gone up on the left of 2 27 upper end of the slideway;As shown in figure 3, the gear aperture apparatus 3 is by supporting rod 31, cunning
Axis 32, casing 33, electromagnet 34, compression spring 35, swingle 36 and rubber cup 37 form;34 lower end of the electromagnet is fixed in rear shell
On the bottom plate of 1 vacuum area of body, the affixed casing in upper end 33;The compression spring 35 is sleeved on casing 33;36 upper left face of the swingle is solid
Connect rubber cup 37, right end riser setting through-hole is connected with supporting rod 32, below in affixed 32 plug-in-sleeve 33 of slide-bar in centre and can
It is slided along internal surface of sleeve pipe;As depicted in figs. 1 and 2, the intelligence control system 4 controls electricity by microcontroller as core processor
Magnet is powered and power-off, and signal projector 41 and the pairing of signal receiver 42 receive feed mechanism for seed broadcast leakage signal using detection;Such as Fig. 4
Shown, two circle suckers are arranged in the discharge plate 5 thereon, and outer ring sucker 52 is main seeds elimination structure, and inner ring sucker 51 is that substitute is arranged
Kind structure, structure feature are:The two circle big smallest numbers of sucker are equal, misplace on discharge plate uniformly distributed;The inner ring sucker 51 begins
Final position is in vacuum area;As shown in figure 5, described scrape kind of device 6 by outer seed scraping device 61, interior seed scraping device 62 and scrape kind of seat 63 and form;
It is described to scrape the outer seed scraping device 61 of the affixed cylinder in 63 positive front end of kind of seat, the preceding affixed arc-shaped interior seed scraping device 62 of right end, and be respectively used to
Outside, interior two circles sucker scrapes kind, to reduce feed mechanism for seed replay rate.
Operating process:
Before sowing machine operation, first the present invention is mounted on seeder.When seeding operation, negative pressure makes feed mechanism for seed back casing 1 and row
Vacuum chamber is formed between discharge plate 5, the transmission shaft band dynamic metering plate 5 of seeder rotates, and 5 inner ring sucker 51 of discharge plate is in upper kinds of bank deposits room
Kind is inhaled in 26, outer ring sucker 52 inhales kind in lower kinds of bank deposits room 25, and suction hole band kind leaves kinds of bank deposits room, and kind of device 6 is scraped in arrival, when
When the inhaled seed of suction hole is more than one, scrapes the outer seed scraping device 61 on kind of device 6 and scrape extra seed in outer ring sucker 52, inside scrape
Kind device 62 scrapes seed extra in inner ring sucker 51, to ensure that each suction hole only retains a seed, reaches precision drilling;
The seed scraped enters back kind of a bridge 23 through slideway 2 27, eventually enters into lower kinds of bank deposits room 25;When the inhaled seed of seeds sucker only has one
When grain, to scrape kind of device 6 and do not work, suction hole band seed is rotated further by seed scraping device, when rotating to non-real dead zone, outer ring
Sucker 52 inhales kind and is no longer influenced by negative pressure, falls under the effect of gravity, completes seeding.At the same time, discharge plate inner ring
Sucker 51 also inhales kind of a rotation, and when intelligence control system 4 does not send out mending-leakage signal, the electromagnet 34 1 kept off in aperture apparatus 3 is straight-through
Electricity does not work, reach the seed in vacuum chamber lower part inner ring sucker 51 continue up through the roads Hui Zhong 24 be up shipped up to by
Baffle 21 scrapes, and the continuation of inner ring sucker 51 for being scraped seed is up moved into kinds of bank deposits room 26, into the fortune kind of a new round
Work, while the seed being scraped successively enters lower kinds of bank deposits room 25 through slideway 1 and time kind of bridge 23;When intelligence control system 4 is sent out
When going out mending-leakage signal, i.e., without seed in outer ring sucker 52, in an ON state, broadcast leakage signal transmits for transmitter 41 and receiver 42
To the microcontroller in intelligence control system 4, and the electromagnet 34 controlled in gear aperture apparatus 3 powers off, and compression spring 33 will be hinged on support
Swingle 36 on bar 31 is released, and rubber cup 37 travels forward and blocks inner ring sucker 51 thereon, and it is zero to make its negative pressure, seed
It falls, completes mending-leakage.The device goes detection broadcast leakage by intelligence system, controls mending-leakage, keeps mending-leakage movement response rapid, sensitive,
Substantially reduce the leakage sowing rate of feed mechanism for seed;Extra seed is wiped off by scraping kind of device, avoid repeat sowing, and then greatly simultaneously
Improve the quality of planting with sowing machine.
