Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of zero speed of seed dropping mechanism being used cooperatively with feed mechanism for seed.
Background technology
With the development of accurate seeding technique in China's agricultural, the zero speed of seed dropping in seeding operation has become guarantee and reality
The now necessary requirement of accurate seeding operation.So-called " zero speed of seed dropping " refers to that the seed being discharged out of feed mechanism for seed is being fallen in kind of a bed soil earth
The horizontal velocity of moment is zero when on surface.During zero speed of seed dropping, seed when being contacted with kind of a bed soil surface relative to
Soil surface without sliding, without bounce, the plant spacing pass rate and accuracy rate of sowing is greatly improved, ensure that seeding operation
Quality.In recent years, numerous universities and colleges, agricultural sciences academy and institute in one's power agricultural machinery enterprise for meet and realize " zero speed of seed dropping " carry out
Equipment researchs and develops, but fails to reach agriculture requirement always.
Invention content
The purpose of the invention is aiming at the actual needs of above-mentioned " zero speed of seed dropping " operation, a kind of zero-speed of design offer
It charges seed mechanism, achievees the purpose that realize zero speed of seed dropping, ensures seeding operation plant spacing pass rate and accuracy rate.
What the purpose of the invention was realized in：Drive shaft, eccentric disc are rotatably inserted on fixed hub
Be packed on fixed hub periphery position, on the eccentric disc cylindrical outer surface by bearing rotatably be equipped with
Runner disc, concentric on one side end of the drive shaft to be fixedly mounted with active wheel disc, the axis in the upper and lower opposite side portion of seed casting pipe
What heart line was mutually parallel be fixedly mounted with respectively turn axis and under turn axis, rotatably insert by above turning axis with servo-actuated wheel disc coordinate and under
It turns axis and active wheel disc and rotatably inserts cooperation and seed casting pipe is fitted between servo-actuated wheel disc and active wheel disc on position, and institute
The axial line for stating seed casting pipe configures in vertical direction, and the axis pin of suit torsion return spring, which is mounted on down, to turn on axis, control of charging seed
Door can circle swing be sleeved on axis pin, one end of torsion return spring location fit on axis pin, the other end with
Control door of charging seed is engaged, and control block of charging seed, the control block of charging seed are equipped in the active wheel disc interior sidewall surface
With control door of charging seed in being engaged or disengage cooperation, charges seed control door described in realization and seed casting pipe lower end is charged seed the beating of mouth
On or off is closed, and a kind of zero speed of seed dropping mechanism is so far constituted.
The invention is used cooperatively with feed mechanism for seed, to seed in the seed that feed mechanism for seed is discharged is conveyed and charged seed
Movement controlled, ensure charge seed direction it is perpendicular to the ground always while so that the seed for being in position of charging seed has
It moves ahead the opposite horizontal tangential speed of directional velocity with equipment, to be offseted with the equipment speed that moves ahead, avoids seed in soil
Zero speed of seed dropping is realized in sliding on earth and spring；Mechanism also considerably reduces seed casting point height and position, reduces seed and hangs down
The acceleration directly to fall；Mechanism structure novel, operation quality is good, and using reliable, generalization degree height, ability to provide the auxiliary items is strong.

Specific implementation mode
The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of zero speed of seed dropping mechanism, in fixation
Drive shaft 2 is rotatably inserted on axle sleeve 1, eccentric disc 3 is packed on 1 periphery position of fixed hub, in the bias
Servo-actuated wheel disc 5 is rotatably equipped on 3 cylindrical outer surface of disk by bearing 4, it is concentric on 2 one side end of the drive shaft
Be fixedly mounted with active wheel disc 6, what axial line was mutually parallel in the upper and lower opposite side portion of seed casting pipe 12 be fixedly mounted with respectively turns 13 He of axis
Under turn axis 7, by above turn axis 13 and servo-actuated wheel disc 5 rotatably inserting cooperation and under turn axis 7 and rotatably inserted with active wheel disc 6
Assembly closes and seed casting pipe 12 is fitted between servo-actuated wheel disc 5 and active wheel disc 6 on position, and the axial line of the seed casting pipe 12 is in
Vertical direction configures, and the axis pin 10 of suit torsion return spring 9, which is mounted on down, to turn on axis 7, and charging seed control door 11 can circle swing
Be sleeved on axis pin 10, one end of the torsion return spring 9 location fit on axis pin 10, the other end and control of charging seed
Door 11 is engaged, and control block 8 of charging seed is equipped in 6 interior sidewall surface of active wheel disc, and described charge seed controls block 8 and throw
Kind of control door 11 charges seed control door 11 and 12 lower end of seed casting pipe is charged seed mouth in being engaged or disengage cooperation described in realization
It opens or closes.
When operation, the seed being discharged by feed mechanism for seed enters the throwing positioned at servo-actuated wheel disc 5 and 6 upside position of active wheel disc
In kind pipe 12, control block 8 of charging seed at this time disengages cooperation with control door 11 of charging seed, in the effect of torsion return spring 9
Under, mouthful block of charging seed of 12 bottom end of seed casting pipe is in closed state by control door 11 of charging seed；Outer defeated rotary power drives through drive shaft 2
The 6 concentric rotation of active wheel disc, active wheel disc 6 rotary motion warp under turn axis 7, seed casting pipe 12, on turn axis 13 drive supporting roller
Disk 5 does the eccentric rotary relative to drive shaft 2 and active wheel disc 6 on eccentric disc 3, while the seed casting pipe 12 of unitary rotation begins
Plumbness is kept eventually, when filling seed-bearing seed casting pipe 12 and turning at servo-actuated wheel disc 5 and 6 downside position of active wheel disc, is thrown
Kind of control block 8 and control door 11 of charging seed are engaged, and making to charge seed controls door 11 and rotated on axis pin 10, by 12 bottom end of seed casting pipe
Mouth opening of charging seed, seed is broadcast in vertical state to be come on kind of bed soil earth, and the seed casting pipe 12 is charged seed the linear velocity and machine of position
Tool moves ahead, and speed is equal, and direction is on the contrary, realize the zero speed of seed dropping operation of seed.After charging seed, control block 8 of charging seed is detached from and throws
The contact of kind control door 11, under the action of torsion return spring 9, control 11 return of door of charging seed, by the throwing of 12 bottom end of seed casting pipe
The salty new block of kind is in closed state.It recycles successively.
