Embodiment Construction

[0015] Such as figure 1 and figure 2 As shown, the present invention comprises nozzle pipe (1), static plate (2), moving plate (3), sealing ring (4), snap ring (5), ratchet (6), rocking arm (7), driving lever ( 8), parts such as spring (9).

[0016] The working process is:

[0017] When the rocker-arm nozzle is working, the water flows out from the outlet, impacts the rocker arm (7), deflects the rocker arm (7), and the elasticity of the rocker arm spring makes the rocker arm (7) strike the nozzle pipe (1) to make the nozzle step. At the same time, the driving lever (8) on the rocker arm slides on the teeth of the ratchet (6) due to the elasticity of the spring (9), knocks a tooth in the ratchet (6), and the ratchet (6) steps along the circumferential direction once, dialing The rod (8) slides down automatically, the moving piece (3) is tightly fitted with the ratchet (6), the ratchet (6) drives the moving piece (3) to step together, and the static piece (2) is threadedly ...

Abstract

The invention belongs to key equipment for water-saving irrigation and relates to a rocker-arm nozzle outlet regulating device which can automatically change range when a sprayer works. The device comprises a spray pipe (1), a static plate (2), a movable plate (3), a sealing ring (4), a snap ring (5) and a ratchet wheel (6) and is characterized in that a driving lever (8) on a rocker arm (7) of the rocker-arm sprayer knocks one tooth of the ratchet wheel (6) to enable the ratchet wheel (6) to rotate to drive the movable plate (3) to rotate, and the movable plate (3) and the static plate (2) move relatively to enable the sectional area of the nozzle to change when the sprayer is in stepping A nozzle change device is added at the nozzle of the sprayer, the relative movement of the movable plate (3) and the static plate (2) changes intercepting space at the inlet of the nozzle so as to regulate flow and pressure at the inlet, thereby changing the range of the nozzle and realizing irregular boundary area spraying.

Description

technical field [0001] The invention belongs to the field of water-saving irrigation and sprinkler irrigation machinery, in particular to a rocker-arm type outlet nozzle adjustment device. Background technique [0002] The 21st century will be an era of rapid social and economic development in my country, and an era of unprecedentedly sharp contradictions between supply and demand of water resources. Vigorously developing water-saving irrigation is the fundamental way to solve the shortage of agricultural water in our country. The sprinkler head is the key equipment that affects the quality of sprinkler irrigation. The traditional nozzles are mainly full-circle sprinkler rocker nozzles, which are widely used due to their stable performance and wide application range. However, when the sprinklers are used in a single or single-row configuration, the spraying perimeter and the spraying plot are often not matched, resulting in a large number of missed spraying, over-spraying ...
