Embodiment 1
The mechanism 1 of holding one's breath is the intermediate hemispheric structure containing round stomata 1, and one 5 the inside of mechanism of holding one's breath includes
Permanent magnetism ball 18, the diameter of mechanism of holding one's breath 1 should both ensured through mechanism 1 of holding one's breath between 2.5 to 3 times of 18 diameter of permanent magnetism ball
Ventilatory capacity, it is sphere in turn ensure that permanent magnetism ball 18 has sufficient activity space, permanent magnetism ball 18, and 18 diameter of permanent magnetism ball is more than stomata
One 19 and inhale kind of 3 diameter of mouth, permanent magnetism ball 18 can the free movement in mechanism 1 of holding one's breath, permanent magnetism ball 18 is under the action of permanent magnet 6
Stomata 1 can be completely enclosed.
When operation, transmission mechanism drives air-aspiration type precision seeding disc spins, and gas passes sequentially through suction under the action of wind turbine
Kind mouth 3, mechanism of holding one's breath 1, stomata 1, negative pressure chamber 13, air intake passage 12 are discharged, and negative pressure is generated in negative pressure chamber 13,
Seed is attracted to successively on suction kind mouth 3 under the action of negative pressure, in the process, since the quality of permanent magnetism ball 18 is more than seed
Quality, so can realize seed by absorption the state of the free movement in mechanism 1 of holding one's breath of permanent magnetism ball 18, when the machine of holding one's breath
When structure 1 is by near permanent magnet 6, due to the interaction of magnetic force and the spherical structure features for mechanism 1 of holding one's breath, permanent magnetism ball
18 are absorbed and fixed on stomata 1, realize the function of planting of holding one's breath, and due to the effect of gravity and are closed after by permanent magnet 6
The spherical structure features of mechanism of qi structure 1, the free movement in mechanism 1 of holding one's breath again of permanent magnetism ball 18.
To prevent magnetic ball from interfering the contact for inhaling kind of mouth 3, a limiting device can be added between disc and magnetic ball, to increase
Add the longitudinally-moving space of permanent magnetism ball 18 that can suitably increase the semi-circular ends length for mechanism 1 of holding one's breath, forms cylinder+semi-circular structure
Mechanism 1 of holding one's breath.
Embodiment 2
The mechanism 2 20 of holding one's breath is the intermediate semi-circular cylindrical structure containing round stomata 2 22, and limiting device 21 stretches out circle
Permanent magnetism piece 23 is fixedly mounted in the end of 2 22 part of shape stomata, and the diameter of dress permanent magnetism piece 23 is more than the diameter of stomata 2 22, limit
Certain spacing is maintained with permanent magnet 6 when device 21 is fully extended, is limited after 21 cross of device adds circular ring structure to block
The gas passage of stomata 2 22 is greater than suction kind mouth 3, ensures the structure space for having enough flux, when limiting device 21 is shunk completely
Bottom end does not contact seeding disc 1, and permanent magnetism piece 23 is same polarity magnet with 6 corresponding surface of permanent magnet, and mutually exclusive, permanent magnetism piece 23 is forever
Stomata 2 22 can be completely enclosed under the repulsion effect of magnet 6,2 20 inner wall smooth of mechanism of holding one's breath is convenient for the longitudinal direction of limiting device 21
Movement, it includes the smooth cross of two outer walls that can have certain moving range, limiting device 21 along the inner wall for mechanism 2 20 of holding one's breath
Add circular ring structure, convenient for limiting and gas passes through.
When operation, transmission mechanism drives air-aspiration type precision seeding disc spins, and gas passes sequentially through suction under the action of wind turbine
Kind mouth 3, mechanism of holding one's breath 2 20, stomata 2 22, negative pressure chamber 13, air intake passage 12 are discharged, and negative pressure is generated in negative pressure chamber 13,
Seed is attracted to successively on suction kind mouth 3 under the action of negative pressure, in the process, since the effect permanent magnetism piece 23 of negative pressure drives
Limiting device 21 stretches out stomata 2 22, and the cross among limiting device 21 adds the longitudinal direction of circular ring structure limitation limiting device 21 to stretch
Go out, the cross of 21 end of limiting device adds the horizontal swing of 21 end of circular ring structure limitation limiting device, enables limiting device 21
Preferable metastable state is enough kept, when mechanism 2 20 of holding one's breath is by permanent magnet 6, due to the mutually exclusive work of homopolarity magnetic force
With permanent magnetism piece 23 is crushed on stomata 2 22, the function for planting of holding one's breath is realized, after by permanent magnet 6, due to gas chamber negative pressure
Effect, permanent magnetism piece 23 drive limiting device 21 to stretch out stomata 2 22 again.
Driven sucking precise solid matter discharge plate as described herein and air-suction seeding unit are made of non-magnetic material.
Although conceiving to the object of the invention with reference to attached drawing and example elaborating, those skilled in the art can
It recognizes, under the precondition of no disengaging claims limited range, various improvement still can be made to the present invention
And transformation, and this modifications and variations should belong to the scope of protection of the present invention.
