Light reel sprinkling irrigation machine sprinkling truss

A light reel sprinkling irrigation machine sprinkling truss comprises a vehicle frame (1), support rods (2) and a suspension arm (3) arranged on the two support rods (2) which are bilaterally symmetrical. The support rods (2) are fixedly installed on the vehicle frame (1), and a plurality of nozzles (4) are evenly distributed on the suspension arm (3). The sprinkling truss further comprises a suspension arm pull rod (5) and a steel wire (6). The suspension arm pull rod (5) is fixed on the vehicle frame (1), and the suspension arm pull rod (5) is connected with the suspension arm (3) at the positions close to two ends through two symmetrical detachable steel wires (6). The suspension arm pill rod (5) is connected with the suspension arm through the detachable steel wires, the connection strength of the suspension arm and the support rod can be further stabilized in the crop sprinkling process, refraction type nozzles are evenly arranged on the suspension arm, a water fertilizer can be applied to the root of the crop accurately in place, the utilization rate of the water fertilizer is improved, and damage of some powerful fertilizers to the leaves of plants is avoided.
