Specific embodiment
The invention embodiment is described in detail with reference to the accompanying drawing.A kind of and matching used electricity of feed mechanism for seed
Control strength blows the seed spout 3 that She Shidaozhong mechanism includes seeding-apparatus assembly 1 and is connected to the seeding-apparatus assembly 1, described defeated
The equipped air flow blowing and jetting grain conductor 4 being interconnected on kind 3 lower end of pipe, defeated kind of sensor 2 are fitted on seed spout 3；In frame body
Cylinder block 18 is fixedly mounted on 16, what rack-and-pinion piston 19 was axially movable is mounted on 18 fluid chamber of cylinder block, in the cylinder block 18
In body cavity, compression spring 17, the both ends of the compression spring 17 are equipped at position between rack-and-pinion piston 19 and frame body 16
Face is engaged with rack-and-pinion piston 19 and frame body 16 respectively, is parallel to each other and can be rotated at 18 outside left of cylinder block
I axis 11 of configuration and II axis 13, electric notor 10 and driving gear 12 be packed on I axis 11, driven gear 14 and sector gear 15
It is packed on II axis 13, the driving gear 12 is engaged with driven gear 14, and the sector gear 15 is in rack-and-pinion piston 19
Cooperation is engaged or be disengaged from, opens up air inlet 8 and gas vent 21, exhaust check valve 20 respectively on the end cap 9 of cylinder block 18
It is fitted on end cap 9, and with gas vent 21 in cooperation is turned off or on, the air inlet end of air flow blowing and jetting grain conductor 4 and end cap 9 are close
Envelope connection, and gas vent 21 is contained, filter screen 22 is fitted in 4 lumen of air flow blowing and jetting grain conductor, is passed through on the end cap 9
Breather check valve 7 is equipped with air cleaner 6, and the air cleaner 6 is in be connected to or close with air inlet 8 by breather check valve 7
Close cooperation；Automatic controller 5 is connected to defeated kind of sensor 2 and electric notor 10 by conducting wire respectively.
When operation, when seed is sent by seeding-apparatus assembly 1 passes through defeated kind of sensor 2 in seed spout 3, defeated kind of sensor 2
The electric notor rotated immediately to automatic controller 5 10 is sent to pass sequentially through I axis 11, driving gear 12, driven gear electric signal
14, II axis 13 driving sector gear 15 rotates, and enters in the seed of seed spout 3 from lower port same in air flow blowing and jetting grain conductor 4
When, the teeth of sector gear 15 are detached to be engaged with 19 rack gear of rack-and-pinion piston, in the case where compression spring 17 acts on, rack-and-pinion piston
19 quickly to mobile at end cap 9, and the gas in cylinder block 18 opens exhaust check valve 20 after being compressed, and pressed gas is through gas vent
21 are blown into seed on kind of bed soil in air flow blowing and jetting grain conductor 4；Thereafter, the teeth and rack gear of the sector gear 15 of rotation
19 rack gear of formula piston enters meshing state, and drive rack formula piston 19 is transported in cylinder block 18 to 17 side of compression pressure spring
Dynamic, gas vent 21 is closed at this time, and breather check valve 7 is opened, and air cleaner 6 is connected to air inlet 8, the air warp in atmosphere
Negative pressure is drawn into cylinder block 18 after filtering, to blow kind of a deposit gas next time, is circuited sequentially.Filter screen 22 avoids air flow blowing and jetting
Impurity in grain conductor 4 blocks gas vent 21.
