Abstract
The invention discloses an air suction plate type seeder. The air suction plate type seeder mainly comprises a rack, a seed suction plate, a seed box, a guide rod, a pneumatic vibrator, a rotating shaft, an air cylinder I, and an air cylinder II. The pneumatic vibrator is arranged on the seed box; the seed box is driven by the air cylinder I to move up and down along the guide rod; and the seed suction plate is driven by the air cylinder II to turn over. The seeder can be used for air suction type precise seeding of small-particle seeds, the seed suction plate moves steadily, and the seed falling caused by shock vibration can be avoided, so that the miss-seeding rate can be reduced and the seedling cultivation cost is lowered.
Description
Technical field
The invention belongs to agricultural machinery precise sowing field, be specifically related to a kind of board-like seeder of aspiration that is applicable to precision seeder.
Background technology
Aspiration type sowing device is the absorption affinity of utilizing air-flow, and seed is adsorbed from kind of heap, realizes simple grain or many s' precise sowing, and to the seed category strong adaptability, injuring-free seed can the high speed operation, is to use at present maximum seeding methods.According to the version of sowing parts, existing air-suction seeding unit mainly can be divided into suction spindle formula, drum-type and suction disc formula.
The operation principle of the board-like seeder of aspiration is: open air pump switch, extract out and inhale kind of the interior gas of backboard section's air cavity, form negative pressure in air cavity, when seed slips over suction hole, be attracted on suction hole; After each sucker sucts seed, to inhale kind of a plate and be turned to directly over the dish of cave, suction hole and dish hole, cave, cave align, and at this moment cut off source of the gas, and in air cavity, negative pressure disappears, and seed falls in dish hole, cave, cave under Action of Gravity Field, completes seeding process one time.
The board-like seeder of existing aspiration, major part is the auto-manual system seeder; The also board-like seeder of some aspiration.Chinese patent ZL200710028007.4 has announced a kind of aspiration plate type hole disc to target seeder, and this device adopts stepper motor to drive the upset of inhaling kind of plate by shaft coupling and L-type axle; Chinese patent ZL201110448955.X has announced a kind of air-sucking vibration plate type precision seeder for field seedling raising, and this device adopts the two degrees of freedom manipulator to drive sucker and moves.Therefore, during the board-like seeder work of existing aspiration, generally adopting reciprocating swing type mechanism or two degrees of freedom manipulator drive suction kind of a plate to inhale plants and seeding, inhale kind of parts in the moving process middling speed, degree can't be stablized, and impacts greatly, easily causes the seed of absorption to come off midway, thereby cause the hole, affect seeding quality.
Summary of the invention
