Description
Technical field
The utility model relates to fertilizer applicator, the Development of Venturi Fertilizer Applicator that in particular a kind of absorption affinity is adjustable.
Background technology
Development of Venturi Fertilizer Applicator can accomplish to apply fertilizer in proportion, constant nutrient can be kept dense, have cheap in irrigation process, easy to use need not the feature of additionaling power.Development of Venturi Fertilizer Applicator is according to venturi principle, because flow velocity during water movement is different thus produce pressure differential, utilizes pressure differential liquid fertilizer to be pressed into a kind of plastics fertilizer apparatus in water transfer pipe network.Specifically be exactly: current pass through one by large gradually little then by (venturi throat) during little gradually large pipeline, current flow velocity when narrow strengthens, pressure drop, make front and back mineralization pressure poor, there is the entrance of a pipe with small pipe diameter in throat, form negative pressure, fertilizer solution is drawn by pipe with small pipe diameter tubule from a uncovered fertilizer tank.The absorption affinity of existing Development of Venturi Fertilizer Applicator is non-adjustable, namely can not regulated fertilization amount as required, and when the insufficient pressure of water transfer pipe network, absorption affinity deficiency also cannot draw fertilizer solution.
utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of Development of Venturi Fertilizer Applicator of adjustable absorption affinity.
For achieving the above object, technical solution of the present utility model is: the Development of Venturi Fertilizer Applicator that absorption affinity is adjustable, comprise Venturi, described Venturi comprises entrance and outlet section, above described Venturi, be communicated with fertilzer sucking pipe, Venturi and fertilzer sucking pipe are one-body molded, and described outlet section comprises the expansion segment and outlet direct tube section that are arranged in order, described fertilzer sucking pipe is connected with the front end of expansion segment, and described entrance is set with disconnectable nozzle; Described nozzle is provided with cavity, and described cavity comprises the entrance direct tube section, contraction section and the trunnion section that are arranged in order.
Preferably, described fertilzer sucking pipe is arranged on the top of nozzle afterbody, and leaves gap between described fertilzer sucking pipe and nozzle.
Preferably, described entrance comprises the cylindrical section and conical section that are arranged in order, and the diameter of described cylindrical section is greater than the maximum gauge of conical section, and described nozzle form volume is consistent with the shaped volumes of entrance, at the tail end of described cylindrical section, the first sealing ring is housed.
Preferably, also comprise joint and spiral cover, joint is connected with the front end of Venturi by described spiral cover.
Preferably, between described joint and Venturi, the second sealing ring is housed.
Preferably, described nozzle afterbody is provided with shirt rim, is also provided with a bulge loop at entrance afterbody, and described bulge loop embeds between shirt rim and outer nozzle wall.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model: the entrance in the utility model Venturi is disconnectable nozzle, the diameter of the shape size of nozzle cavity especially throat's section can be selected as required, adjustment absorption affinity is realized by changing nozzle, to adapt to the demand of different ductwork pressure and Different Fertilization amount, the utility model structure is simple, easy for installation, good seal.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
(identify in figure: 1, Venturi; 2, entrance; 21, cylindrical section; 22, conical section; 3, outlet section; 31, expansion segment; 32, direct tube section is exported; 4, fertilzer sucking pipe; 5, nozzle; 51, entrance straight length; 52, contraction section; 53, trunnion section; 6, joint; 7, spiral cover; 81, the first sealing ring; 82; Second sealing ring; 9, shirt rim; 10, bulge loop).
Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the Development of Venturi Fertilizer Applicator that absorption affinity is adjustable, comprises Venturi 1, and Venturi 1 is divided into entrance 2 and outlet section 3, above described Venturi 1, be communicated with fertilzer sucking pipe 4, and Venturi 1 is one-body molded with fertilzer sucking pipe 4.Entrance 2 comprises the cylindrical section 21 and conical section 22 that are arranged in order, wherein the diameter of cylindrical section 21 is greater than the maximum gauge of conical section 22, form a step, at the tail end (i.e. the junction step of cylinder 21 and conical section 22) of cylindrical section 21, first sealing ring 81 is housed.Entrance 2 is set with disconnectable nozzle 5, and the volume profiles of nozzle 5 is consistent with the volume profiles of entrance 2, load nozzle 5 time, just by the first sealing ring 81 geometrical clamp between nozzle 5 and Venturi 1.The cavity of nozzle 5 comprises the entrance direct tube section 51 and contraction section 52 that are arranged in order, and described outlet section 3 comprises the expansion segment 31 and outlet direct tube section 32 that are arranged in order.Fertilzer sucking pipe 4 is arranged on the top of nozzle 5 afterbody, and leaves gap between described fertilzer sucking pipe 4 and nozzle 5, and namely fertilzer sucking pipe 4 is connected with the front end of expansion segment 31.For being connected with grid, be connected with joint 6 in the front end of Venturi 1, described joint 6 is connected with the front end of Venturi 1, the second sealing ring 82 is housed, enhanced leaktightness between the two.Nozzle 5 afterbody is provided with shirt rim 9, a bulge loop 10 is also provided with at entrance 2 afterbody, described bulge loop 10 embeds between shirt rim 9 and nozzle 5 outer wall, this structure makes nozzle more firmly be sleeved in Venturi 1, being connected of fertilzer sucking pipe 4 and outlet section 3 can also be kept simultaneously, also effectively avoid nozzle 5 too to go deep into blocking in Venturi 1 entrance of fertilzer sucking pipe 4.
In the utility model, the entrance 2 of Venturi is the disconnectable nozzle 5 of suit, the diameter of the shape size of nozzle 5 cavity particularly throat's section 53 can be selected as required, change nozzle 5 can realize adjusting absorption affinity, to adapt to the demand of different ductwork pressure and Different Fertilization amount, the utility model structure is simple, easy for installation, good seal.
