1气吸播种机工作原理气吸式播种器工作时由高速风机产生负压,传给排种单体的真空室。排种盘回转时,在真空室负压作用下吸附种子,并随排种盘一起转动。当种子转出真空室后,不再承受负压,就靠自重或在刮种器作用下落在沟内。气吸式播种器主要影响因素有真空度、吸孔形状、种子尺寸、及刮种器的构造和调整。气吸式播种器的真空度:真空度越大则吸附种子的能力越强,越不易产生空穴;但单个吸孔吸附几粒种子的可能性加大,使
1 air suction seeder works Air suction planter work by the high-speed blower to produce negative pressure, passed to the monomer row of vacuum chamber. Seed plate rotation, the negative pressure in the vacuum chamber adsorption of seeds, and with the seed plate with the rotation. When the seed out of the vacuum chamber, no longer bear negative pressure, rely on their own weight or in the role of scraper fall in the trench. The main influencing factors of the air suction seeder are the degree of vacuum, the shape of the suction hole, the size of the seed, and the structure and adjustment of the scraper. Vacuum degree of air suction seeder: the greater the degree of vacuum, the stronger the ability to adsorb seeds, the less likely to produce holes; but the possibility of a few holes to adsorb a few seeds, so that
