Irrigation device for irrigation and water conservancy engineering

The irrigation device comprises a main machine body, a water pump, a diesel engine and a power box, the power box is fixed to the center of the top of the main machine body, a rotating disc is movably arranged in the center of the top of the main machine body through a limiting wheel, and a main shaft is movably arranged in the center of the interior of the power box; a driven wheel is fixed to the bottom of the main shaft, a rotary driving part is fixed to one side in the power box, the output end of the rotary driving part is connected with a driving wheel, and a belt is connected between the driving wheel and the driven wheel. By starting the rotary driving piece, the rotary driving piece enables the driving wheel to rotate, the driving wheel enables the belt to rotate so as to enable the driven wheel to rotate, the driven wheel enables the main shaft to rotate so as to enable the rotary disc to rotate, and the rotary disc enables the connecting piece to rotate so as to enable the direction of the nozzle t
