目前,生产上常用的喷雾器主要有电动式和背负式两种。电动式喷雾器作业效率高,但步速快,劳动强度大,易发生药害;背负式喷雾器额定容量大,“常压”稳定,但耗水量大,不宜大面积推广应用。1990年,我们将两种喷雾器进行串联,实施化学除草。 1.组装方法选用上海产3 WCD—5型电动超低量喷雾器和晋城产3 WB—16型背负式喷雾器,分别将电动式喷雾器药液瓶和背负式喷雾器喷杆组件拧下,把外径1.5厘米、长1.5米的空心塑料管一头插在螺口中央孔内,另一头密接在滤网组件螺丝上。在背负式药箱内将药液混合均匀,按拉摇杆手柄,调节开关间隙与滴管孔口相同,使药液顺着空心管自然流入雾化盘,按下电源开关,每走6～8步摇动1次手柄,即可雾化作业。
At present, the production of commonly used sprayer mainly electric and knapsack two. Electric sprayer operating efficiency, but the pace fast, labor-intensive, prone to injury; Knapsack sprayer rated capacity, “atmospheric pressure” stable, but the water consumption, should not be large-scale promotion and application. In 1990, we connected two nebulizers in series to carry out chemical weeding. 1. Assemble the method Choose Shanghai WCD-5 electric ultra-low volume sprayer and Jincheng 3 WB-16 type backpack sprayer, unscrew the electric sprayer liquid medicine bottle and backpack sprayer spray bar assembly, respectively, the outer diameter 1.5 cm, 1.5 m long hollow plastic pipe inserted in the central hole of a screw, the other end of the filter assembly screws closely. In the knapsack medicine tank will be mixed evenly, according to pull the joystick handle, adjust the switch gap and the same dropper orifice, so that liquid medicine along the hollow tube into the atomizer disk, press the power switch, each walking 6 ~ 8-step shake 1 handle, you can fog operation.
