Abstract

The invention discloses a needle-socket type anti-blocking artificial field rainfall simulation device. The device is composed of an artificial rainfall device, a raininess test device and a lifting type rainfall machine needle dredging device; with the lifting type rainfall machine needle dredging device, a needle does not need to be pulled out to clean by an iron wire after each rainfall, the cleaning process of the needle is time-saving and labor-saving, the permeability of the needle of a rainfall machine is guaranteed, and stable raininess is provided for an experiment. Furthermore, a whole bottom plate is divided into parts through a needle distribution plate at the bottom of an artificial rainfall machine water tank, and a whole line of needles can be fast replaced by replacing needle distribution plates on which needles of different specifications are distributed, thereby achieving the aim of fast regulating different raininess according to experiment demands, and simplifying the process of replacing the needles while regulating the raininess. Therefore, the needle-socket type anti-blocking artificial field rainfall simulation device disclosed by the invention is excellent in experimental result, and can be widely applied to the artificial field rainfall simulation.

Description

technical field [0001] The invention belongs to the technical field of soil property research equipment, and in particular relates to a pinhole anti-clogging artificial field simulated rainfall device. Background technique [0002] At present, a large number of experiments on soil erosion and solute migration are measured by indoor artificial rainfall in the artificial rainfall hall. Indoor artificial rainfall provided stable rain intensity and uniform raindrop strikes for the experiment, but most of the indoor research focused on simulating the impact of rainfall on disturbed soil, which was affected by human factors, and the measurement results were quite different from the actual situation in the field. Truly represent the actual situation in the wild. Therefore, at present, colleges and universities and scientific research units mostly use side spray simulated rainfall devices or pipe network (spray) to carry out simulation experiments in the field. The two methods of ...
