A double efficient sprayer, which comprises a water tank (24), infusion tube (32), a liquid spraying pipe (6), a handle (1), screw cap (2), a piston rod (19), the extension tube (11) and a nozzle (29), which is characterized in that: with the water tank (24) connected to the infusion tube (32) through the three liquid inlet joint (4) with a liquid spraying pipe (6) connected with the rear end; the connecting pipe (31) at one end and three transverse connector (5) connected to the other end of the spray pipe (6) outside the front of the bolted joint (8) (with a liquid spraying pipe 6) is communicated with the back pressure output tube; (30) the front and rear ends respectively through the screw joint (13) and outer screw joints (20) with a liquid spraying pipe (6) communicated with the piston rod; (19) there is a bidirectional leather wrist top (18); three (4), a liquid inlet joint outside the screw joint (8 A valve bead (3), (6), (9), (14) and (15) are respectively arranged in the outer screw joint (13) and the spray pipe of the outer screw.
【技术实现步骤摘要】
【国外来华专利技术】本技术涉及一种喷雾器,尤其是一种用于对农作物喷洒农药的来复式高效喷雾器。目前,市场上出售的各类喷雾器均存在或这或那的不足,如工农16背负式喷雾器、价格高,背负箱上肩要借地形坡度,操作时左手往下压气,左肩增加重量加大负荷,药剂快完时,压气柄往上提,背负箱也跟着往上提,既麻烦,又劳动强度大;还有一种简易水箭式喷雾器,虽然价格低廉,但每喷一次,就得在另外药剂容器中提吸一次药液,不能连续喷洒,喷雾不均匀,耗药量大,不是间喷就是重喷,功效不高。本技术旨在提供一种价格适中,操作简便,劳动强度低,喷药效果好的来复式高效喷雾器。以下结合附图时本技术予以详细说明附图说明图1为本技术整体结构示意图;图2为喷液管内部结构示意图;图中1、手柄2、螺盖3、阀珠4、三通进液接头5、三通横接头6、喷液管7、垫圈8、外螺接头9、阀珠10、拦销11、延伸管12、雾化接头13、外螺接头14、阀珠15、阀珠16、螺帽17、垫圈18、双向皮腕19、活塞杆20、外螺接头21、密封圈22、上框架23、背带24、水箱25、下框架26、挂销27、皮筋28、支架29、喷咀30、回压输出管31、连接管32、输液管。本技术主要由水箱(24),输液管(32),喷液管(6),手柄(1),螺盖(2),活塞杆(19),延伸管(11)和喷咀(29)构成,其特点是;与水箱(24)相连的输液管(32)通过三通进液接头(4)与喷液管(6)后端相连;连接管(31)一端与三通横接头(5)相连,另一端通过喷液管(6)前部之外螺接头(8)与喷液管(6)相通;回压输出管(30)前、后两端分别通过外螺接头(13)和外螺接头(20)与喷液管 ...
