Abstract
The utility model discloses an improved Venturi fertilizer applicator and relates to the technical field of agricultural tools. A thumb screw is arranged on a pipeline; a metal thread groove is formed in the lower end of the thumb screw, so that an adjustable inside section is formed on the pipeline; a fertilizer solution inlet channel opening is formed in the lower side of the pipeline corresponding to the thumb screw. The improved Venturi fertilizer applicator is simple in structure and convenient to carry and use; during the dropper fertilizer application process, the concentration of the fertilizer solution is adjusted in a manual spiral manner; as four right angles of a common fertilizer applicator are changed into straight tubes, head loss caused by branch pipe connection is reduced, and energy consumption is decreased.
Description
Technical field:
The utility model relates to a kind of modified Development of Venturi Fertilizer Applicator, belongs to agriculture apparatus technical field.
Background technology:
Along with the development of water-saving irrigation technique, fertilizer practice combined with it, the research of particularly fertigation technology is subject to showing great attention to of more and more Water Saving Irrigation Works persons.Fertigation is as advanced water-saving irrigation fertilizer practice, at worldwide spread, the advantage of its water-saving fertilizer-preserving volume increase manifests day by day, to be liquid manure directly enter soil and to all directions diffusion of soil from drip irrigation emitter to its feature, the moisture oozing due to water dropper is moistening crop root zone only, make root system fully absorb irrigation liquid manure, reduce deep percolation and environmental pollution, make the moisture condition of crop be in all the time under optimum state, the periodicity excess moisture of other irrigation methods generations and the generation of water deficit situation have been avoided, significantly improve crop yield and liquid manure utilization ratio.
Development of Venturi Fertilizer Applicator is a kind of generally fertilizer apparatus of application, it is to be installed in parallel with the feed pipe by-pass valve control of irrigation system or porch, irrigated area, during use, by-pass valve control is turned down, before and after causing by-pass valve control, there is certain pressure reduction, make current through the arm of Development of Venturi Fertilizer Applicator is installed, the pull of vacuum of utilizing current to produce by Venturi tube, applies fertilizer fertilizer solution even suction pipe-line system from uncovered fertilizer bucket.
In dropper fertilising process, venturi tube fertilising pipe and feed pipe by-pass valve control are installed in parallel, and as the Yi Ge branch that is connected to supervisor, current will pass through four 90 ° of turnings during by venturi pipeline, serious increase local head loss.This is totally unfavorable in the middle of river construction, and this design has not only increased energy consumption but also wasted material.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of modified Development of Venturi Fertilizer Applicator.
A kind of modified Development of Venturi Fertilizer Applicator of the present utility model, it comprises hand tighten screw, metal threaded groove, fertilizer solution admission passage mouth, on pipeline, be provided with hand tighten screw, the lower end of hand tighten screw is provided with metal threaded groove, make to have formed adjustable flow section on pipeline, the downside of the pipeline corresponding with hand tighten screw is provided with fertilizer solution admission passage mouth.
The beneficial effects of the utility model are: simple in structure, carry with easy to use, in dropper fertilising process by manual adjustable diameter and screw adjusting fertilizer solution concentration, due to four right angles of arm in common fertilizer applicator are become to straight tube, therefore reduced because connecting branch causes the loss of flood peak, reduced energy consumption.
Accompanying drawing explanation:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the structural representation of metal threaded groove in the utility model.
In figure: 1-hand tighten screw; The metal threaded groove of 2-; 3-fertilizer solution admission passage mouth; The adjustable flow section of 4-; The 5-cross-section of river.
Embodiment:
For making the purpose of this utility model, technical scheme and advantage more cheer and bright, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.
As Figure 1-3, this embodiment is by the following technical solutions: it comprises hand tighten screw 1, metal threaded groove 2, fertilizer solution admission passage mouth 3, on pipeline, be provided with hand tighten screw 1, the lower end of hand tighten screw 1 is provided with metal threaded groove 2, make to have formed adjustable flow section 4 on pipeline, the downside of the pipeline corresponding with hand tighten screw 1 is provided with fertilizer solution admission passage mouth 3.
The operation principle of this embodiment is: Development of Venturi Fertilizer Applicator is connected in fertigation hydraulic pipeline, utilize the cross-section of river 5 sizes in manual adjustable diameter and screw adjusting Venturi tube, when the cross-section of river 5 size reduction, before and after causing by-pass valve control, there is certain pressure reduction, make current through the arm of Development of Venturi Fertilizer Applicator is installed, the pull of vacuum of utilizing current to form by Venturi tube, can apply fertilizer fertilizer solution even suction pipe-line system from fluidsupply container; Change existing " groove " type waterline into " one " font waterline, thereby reduced water delivery energy consumption.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
