Abstract

The invention discloses a pumpless float type constant and uniform low-pressure trickle irrigation device, which comprises a water delivery part, a pipe network part and a water dropper part, wherein the pipe network part consists of a main pipe, a branch pipe and a capillary; the water delivery part comprises a water storage tank and an adjustable main pipe water pressure adjusting mechanism; the adjustable main pipe water pressure adjusting mechanism comprises a water supplementing pipe, a slide water supplementing switch, a water transfer tank and a constant water level tank; an unidirectional inlet valve is arranged between the water transfer tank and the constant water level tank; one end of the water supplementing pipe is connected with the water storage tank; the other end of the water supplementing pipe is connected with the interior of the water transfer tank; the slide water supplementing switch is arranged in the water transfer tank and slidingly connected with the slide water supplementing pipe; and the water storage tank is arranged at the upper end of the water transfer tank. Compared with the prior art, the device does not adopt a water pump, but depends on the gravity flow to provide a continuous power source for trickle irrigation; the outflow rate of orifices are identical basically; and the device is excellent in anti-blocking performance and convenient to overhaul, saves water and energy and is appropriate for popularization in vast rural areas.

Description

technical field [0001] The present invention aims at low irrigation uniformity of drip irrigation irrigators under low pressure, poor anti-clogging performance of drippers, unsatisfactory irrigation effect and high cost of use, and a pumpless float type constant and uniform low-pressure drip irrigation device designed by using the present invention The device can implement energy-saving and water-saving automatic uniform irrigation, and belongs to the technical field of agricultural water-saving irrigation. Background technique [0002] The existing low-pressure drip irrigation technology mainly relies on the water pump to provide continuous water supply power in terms of the power required by the dripper for continuous drip irrigation. Under low pressure, the loss of water head in the capillary has a more obvious impact on the uniformity of irrigation, resulting in unequal flow rates from each dripper. Irrigation uniformity is poor. Due to the small size of the dripper flo...
