Problems solved by technology

However, the existing truss-type sprinklers are equipped with small sprinkler nozzles and high sprinkler intensity, resulting in the sprinkler irrigation intensity often greater than the soil infiltration capacity, resulting in surface runoff, causing deep seepage and soil erosion, and reducing the operating efficiency of the sprinkler irrigation machine

Abstract

The invention discloses a pulse truss sprinkling machine and an operation method, and belongs to the technical field of agricultural water-saving irrigation. The pulse truss sprinkling machine comprises a truss, a main pipe, capillary pipes, nozzles, branch pipes, capillary pipe jet flow pulse tee joints and branch pipe jet flow pulse tee joints; wherein the jet pulse tee joint comprises a water inlet, a jet pipe, a jet space, a jet reversing device, an output pipe and an outlet; when the pulse truss sprinkling machine works, pressure water flow enters the water inlet of the jet pulse tee joint, enters the jet space through the jet pipe to form jet flow, is attached to one side wall surface of the jet space and enters the branch pipe or the capillary pipe on the side wall surface; through the reversing effect of the vibrator reversing device, water flow is periodically switched and output at the left outlet and the right outlet, and pulse water flow is generated in the branch pipes and the capillary pipes respectively. Pulse water flows of the branch pipes and the capillary pipes are overlapped and then enter the spray heads, so that the spray heads form a pulse spraying effect, the spray irrigation intensity is reduced, and the spraying uniformity is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and relates to a truss type sprinkler irrigation machine, in particular to a pulse truss sprinkler irrigation machine and an operation method. Background technique [0002] The truss type sprinkler irrigation machine has the characteristics of saving water and labor, a high degree of mechanization, a large single-machine control area, and strong adaptability. In recent years, the scope of promotion and application has been expanding year by year. However, the existing truss-type sprinklers are configured with a small nozzle range and a high sprinkler intensity, so that the sprinkler intensity is often greater than the soil infiltration capacity, and surface runoff occurs, causing deep seepage and soil erosion, reducing the operating efficiency of the sprinkler. The invention designs a pulse truss sprinkling irrigation machine, which has the effect of pulse spraying. T...
