点种器是铺膜播种机的核心部件,关于点种器株距的确定,理论设计与实际运用有一定的差距,多年实践证明,为了清楚描绘点种器滚动一周的周长与株距之间的关系,找出它们之间的变化规律,准确测定点种器的株距参数,应运用测定点种器株距的节圆理论。 一、株距测定的节圆理论 1、点种器工作时,点嘴入土后,滚动一周所经过的距离等于这个点种器点嘴数乘以株距之间的平均距离。滚动一周形成的圆,称为节圆;滚动一周经过的距离,称为节圆周长。节圆周
Dot seed planter is the core component of the planter, the point of plant spacing to determine the theoretical design and practical use of a certain gap, many years of practice has proved that, in order to clearly describe the point of the perimeter of a rolling device and spacing between Relationship, find out the law of variation between them, and accurately measure the plant spacing parameters of the seed, should be used to determine the plant pitch pitch circle theory. First, the determination of pitch pitch circle theory 1, the point of work when the mouth after the mouth into the soil, the distance traveled through a week is equal to the point multiplier dot spacing multiplied by the average distance between plant spacing. Rolling a circle formed by the week, known as the pitch circle; rolling a week through the distance, known as the pitch circle circumference. Festival circle
