Description
Technical field
The present invention relates to a kind of injection nozzle, particularly about a kind of injection nozzle for center pivot sprinkling machine sprinkler irrigation fertilization, belong to water-Saving Technology of Contemporary Agriculture field.
Background technology
Fertigation is the key character of modern intensive Irrigation farming.Application center pivot sprinkling machine carries out sprinkler irrigation fertilization operation to crop, can accurately control irrigation time, dose, ratio between fertilizer solution concentration and nutrient, raising water and fertilizer utilization, and reduces the pollution to environment to greatest extent.According to incompletely statistics, the recoverable amount of national center pivot sprinkling machine in the end of the year 2011 is ended more than more than 7000 covers, irrigated area about 3,500,000 mu.According to " national water-saving irrigation " 12 " planning ", in provinces and regions, the northeast four high-efficiency water-saving agricultural irrigation area implemented, center pivot sprinkling machine will more than 1,000 ten thousand mu.But, current domestic shortage and the supporting fertile equipment of special note of center pivot sprinkling machine, center pivot sprinkling machine seldom realizes sprinkler irrigation fertilization operation, and substantially continues to use traditional fertilization mode, cause utilization rate of fertilizer and fertilising uniformity low.And by contrast, within 1998, U.S.'s center pivot sprinkling machine sprinkler irrigation fertilization area accounts for the proportion of irrigation area more than 35%.
During center pivot sprinkling machine sprinkler irrigation fertilization, unit is in walking states, this service behaviour to fertilizer apparatus requires higher, require the fertilizer-injecting flow rate of fertilizer apparatus or note fertile fertilizer solution concentration not by the impact of variation in water pressure in irrigation conduit, and accurately can control fertilizer-injecting flow rate and total fertilization amount etc.Therefore the center pivot sprinkling machine sprinkler irrigation fertilization operation fertile pump of note of often selecting external impetus to drive, as the membrane pump that agriculture medical instruments factory produces, guarantees that the fertilizer solution concentration injecting center pivot sprinkling machine water-main is stablized.
Injection nozzle is the key equipment of the pouring-in sprinkler irrigation fertilization device of pump, and its bleed type, specification and mounting means all can have influence on the mixed effect of solution, and then affects the fertilising uniformity of irrigation system; In addition, nozzle also should have one-way flow function, in the fertilizer bucket preventing from the irrigation water reverse flow of water-main from entering storing prewired solution.Can say, whether the service behaviour of injection nozzle reaches designing requirement by finally affecting center pivot sprinkling machine sprinkler irrigation fertilization.The injection nozzle of a excellent performance, had both required its good mechanical property, and namely structure is simple, reliable operation; Require that again its hydraulic performance is good, the main technical requirements of sprinkler irrigation fertilization can be met.At present, domestic minority realizes the center pivot sprinkling machine of sprinkler irrigation fertilization, and its injection nozzle adopts the pipeline of certain section 1/2 inch or 3/4 inch to substitute, and directly in insertion center pivot sprinkling machine water-main, do not have backflow preventing structure, the mixed effect of solution and irrigation water is poor; And some are for the similar injection nozzle of oil, medicine and other fields, profile and mounting means have more specificity.On the whole, most of injection nozzle not designs for center pivot sprinkling machine sprinkler irrigation fertilization, and the current aspect such as profile, mounting means, inner flow passage, gear plunger type formula, the import and export mix for the injection nozzle of center pivot sprinkling machine is unsuitable for the efficient sprinkler irrigation fertilization operation of center pivot sprinkling machine.
