suction pump

Aiming at the problem that the seeds picked up by the suction plate of the seed metering device cannot accurately fall into the seed pit opener as well as into the seed pit , an innovated seed metering device on which the seed dropping angle can be adjusted within a certain range and a new testing stand have been developed in accordance with the mathematical calculation model that had “ in accordance with the mathematical calculation model that had been established previously . then an experimental study is conducted and the seed dropping law has been found out through the study 本論文根據2bqm - 2型氣吸式精量鋪膜播種機的結構和工作原理,針對該機在實際播種中,吸種盤吸出的種子不能滿足準確地落入在膜上滾動開穴的鴨嘴內,并及時地排入到鴨嘴所成的穴孔內的設計要求,進行了一定的試驗研究,利用已建立的計算數學模型,設計新的試驗臺,改進排種器,使排種器的落種角度可以在一定的范圍內調整。
