A comprehensive test device for anti-clogging performance of drip irrigation emitters

Abstract

The invention relates to a comprehensive testing device for the anti-clogging performance of drip irrigation emitters. The comprehensive testing device is characterized by comprising a frame, wherein a water supply system is arranged below the frame; a drip irrigation system is arranged above the frame; a composite moving device is arranged below the drip irrigation system; a water collecting tank is arranged under the composite moving device; the water supply system comprises an adjusting water tank; a water pump suction pipe is arranged on the side face of the adjusting water tank; the other end of the water pump suction pipe is connected to a water pump; the water outlet pipe of the water pump is connected to primary shunt pipes and secondary shunt pipes respectively; the primary shuntpipes extend into the adjusting water tank respectively; the tail ends of the secondary shunt pipes are connected to a filter bank respectively; the filter bank is connected to the drip irrigation system respectively; the drip irrigation system comprises a drip irrigation pipe, a plurality of drip irrigation emitters and a plurality of water holding units; and the water holding units are arrangedon the top of the composite moving device. The comprehensive testing device can be used for solving the problems of single function, low intelligent degree, not high test accuracy and the like of thepreceding anti-clogging performance testing device, and can be widely applied to the comprehensive test of the anti-clogging performance of the drip irrigation emitters.

Description

technical field [0001] The invention relates to a test device, in particular to a comprehensive test device for anti-clogging performance of a drip irrigation emitter. Background technique [0002] The drip irrigation emitter is one of the most critical components of the drip irrigation system. Due to the narrow flow channel of the drip irrigation emitter (generally only 0.5-1.2mm), impurities such as suspended solids, dissolved salts, chemical precipitation, organic matter, and microorganisms in the water are easily caused. The flow channel and outlet hole of the drip irrigation emitter are blocked, and the water quality factor is the most direct cause of the blockage. Drip irrigation system clogging can be divided into three types: physical, chemical and biological clogging. Among them, physical clogging refers to clogging caused by organic (biological residue) or inorganic (sand, silt and clay) suspended matter contained in water, chemical clogging It is usually caused b...

Problems solved by technology

Many irrigation research institutes and production institutions, such as the California Irrigation Technology Research Institute in the United States, the South African Agricultural Engineering Research Institute, and the Israeli NETAFIM Modern Agriculture Company, all have their own hydraulic performance test platforms for drip irrigation emitters, but the test systems are relatively large, and the investment is high. Single, different standards, and only stay in the hydraulic performance test stage, only the device developed by the California Institute of Irrigation Technology involves a simple anti-clogging performance test

Domestic Li Guangyong et al. (Patent No.: 03149903.1) disclosed a drip irrigation emitter anti-clogging and hydraulic performance comprehensive test device, which realized the comprehensive test of the drip irrigation emitter hydraulic performance and anti-clogging performance, mainly focused on the hydraulic performance test, The anti-clogging performance test of drip irrigation emitters is relatively simple, but there are also problems such as complex system structure, high cost, and limited intelligence.
