在播种作业中,经常要将划印器由作业机组的这一边移到另一边,这样很耽误时间。今年我们设计了一种可以自动起落的划印器,并已制成了一台,在原地试验时,起落自如(在实际作业中是否存在问题,尚待试验)。今将划印器的制造方法介绍如下,以供大家作进一步的研究。自动升降划印器是按照联接四台播种机作业的宽度设计的,分左右两部,当作物行距为15公分时,左边全长8,205公厘,右边全长6,345公厘。播大豆和其他作物时,因行距不同,可以随意调整 In sowing operations, it is often time-consuming to move the scribe from the side of the work unit to the other side. This year we designed a kind of scribing device that can automatically take off and land, and has made a set, which can be up-and-down freely when it is in-situ test (whether there is any problem in the actual work yet to be tested). Now the manufacturing method of scribing device is introduced as follows, for your further study. Automatic lifting scriber is in accordance with the width of the four seeding machines connected to the design, divided into about two, when the crop row spacing of 15 cm, the full length of the left 8,205 mm, the right length of 6,345 mm. Sow soybeans and other crops, due to different line spacing, can be adjusted
