FIELD: agriculture. ^ SUBSTANCE: invention concerns agriculture, particularly plant protection devices. Bar sprinkler includes frame where a bar with sprinklers and work fluid tank are mounted on suspension device, the tank connected to sprinklers by hydraulic main featuring pump with work fluid flow controller. Bar is divided at least into one middle and two lateral sections, each lateral section attached to suspension device by interlinked vertical and horizontal joints. Each lateral section can rotate against the last joint around lengthwise section axis and is additionally attached to the suspension device by three cables, with two cables attached to upper supports of suspension device and one cable attached to lower support. The cables are sprung against supports, allowing for significant reduction of shock impact and swaying amplitude of lateral bar sections against the frame during bar sprinkler operation, and thus maintain bar protection against damage. ^ EFFECT: significant reduction of bar break possibility by the contact of loose bar ends with ground surface or obstacle. ^ 3 dwg |
