adding kind of a case guide groove 1242, when adding kind of case 43 and moving to add kind of case guide groove 1242 end, Motor 2 41 shuts down, and motor 3 434 starts running, and driven gear 4 436 operates, the gear five being meshed therewith 439 operatings, thus drive link 438 rotates, and allows with sponge rotor plate 435 to medial motion, so that sponge 4352 is pasted Tightly adding kind of pipe 437, reach seed and cannot continue to fall, the seed adding kind of case 43 is uniformly added in trapezoidal kind of case 21, adds The process of kind terminates.After adding and having planted, controller 5 controls motor 1 reversion, thus driven gear 2 38 adverse movement, And then driving rotary shaft 33 to rotate backward, seeds sucker connecting plate 36 rotates backward therewith, until seeds sucker 35 moves Time directly over trapezoidal kind of case 21, motor 1 shuts down.Electricity during controller 5 controls vibration seed tray device 2 simultaneously Magnetic vibrator 25 is started working, and electromagnetic vibrator 25 drives oscillating plate 22 up-down vibration, simultaneously straight on linear bearing 24 Bobbin holds take-off lever 241 and moves up and down, and vibrating spring about 26 deforms, thus drives on the seed group in trapezoidal kind of case 21 Lower vibration, air pump 62 is started working, and is passed through negative pressure by telescopic plastic flexible pipe 61 to inhaling kind of a device, and hydraulic cylinder exports Bar 342 moves down, and drives seeds sucker 35 to move down so that the suction nozzle 352 in seeds sucker 35 is near trapezoidal kind of case 21 Interior seed group, cylinder cavity 3562 enters negative pressure, cylinder take-off lever 3563 by cylinder air inlet/outlet 3561 simultaneously Move upward, drive thimble link 357 to move upward, thus thimble 353 is away from suction nozzle 352, when in seeds sucker 35 Suction nozzle 352 is with when in trapezoidal kind of case 21, the seed group of motion contacts, and hydraulic cylinder take-off lever 342 stop motion, seed is inhaled To inhaling on kind of mouth 352, hydraulic cylinder take-off lever 342 dwell time is set to 1s, and then hydraulic cylinder take-off lever 342 moves up, Seeds sucker 35 is driven to move up, when seeds sucker 35 is moved upwards up to suction nozzle 352 position higher than trapezoidal kind of case 21 upper end During face, motor 1 is started working, and driven gear 1 rotates, thus driven gear 2 38 rotates, and then drive turns Moving axis 33 rotates, and rotates along with rotary shaft 33 therewith seeds sucker connecting plate 36 and rotates, thus drives seeds sucker 35 to rotate, During seeds sucker 35 rotates, after seeds sucker 35 relative initial position turns over 45 °, hydraulic cylinder take-off lever 342 is downward Mobile, drive seeds sucker 35 to move downward, when turning over 90 °, motor 1 quits work, simultaneously hydraulic cylinder take-off lever 342 stop motions, seeds sucker 35 carries out seeding, and now controller 5 controls air pump 62 and is passed through positive air pressure, is passed through positive air pressure Rear seed falls in the middle of kind of dish from suction nozzle 352, and cylinder cavity 3562 enters positive air pressure by cylinder air inlet/outlet 3561 simultaneously, Cylinder-driven axle 3563 moves downward, and drives thimble link 357 to move downward, thus thimble 353 moves downward and reaches Eject undischarged seed in suction nozzle 352.After seeding completes, motor 1 is started working, and repeats said process, when Seed in trapezoidal kind of case 21, less than time a certain amount of, carries out above-mentioned adding kind of a process.It is less than certain when adding seed in kind of case 43 Carry out during amount manually being added in kind of case 43 by seed.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention Any amendment, equivalent or the improvement etc. made within god and principle, should be included in protection scope of the present invention it In.
