Description
Technical field
The utility model belongs to agricultural spray device technical field, is specifically related to a kind of air suction type agricultural sprayer nozzle of flow-controllable.
Background technology
At present, spray pesticide is main, the most effective means of disease pest and weed integrated control in China's agricultural production.Interrelated data shows, and in use, effective rate of utilization is only about 20% to China's agricultural chemicals, and the agricultural chemicals of 80% floats in air, works the mischief to environment and human health.How effectively to improve agricultural chemicals to target deposition, the drift of minimizing agricultural chemicals becomes the subject matter that China's technique in using agriculture chemical faces.Domestic and international research shows, spraying droplet size is the one of the main reasons causing agricultural chemicals to drift about, and fogdrop diameter is less, easier wind-engaging and climatic influences and produce drift.Special in fogdrop diameter is less than 150 μm, droplet very easily produces drift.Shower nozzle is the atomising device of liquid, is the critical component directly affecting spraying droplet diameter and atomization quality.Current China mister head kind is comparatively single, and it is main for being mainly eddy spray head, and its droplet produced drips based on the mist that diameter is 100 ~ 200 μm, and the droplet very easily producing drift accounts for more than 30 ~ 50% of total spray amount.Therefore, by changing nozzle structure, develop a kind ofly can improve spraying droplet diameter, effectively reduce agricultural chemicals drift, the air suction type agricultural sprayer nozzle of flow-controllable is desirability.
Summary of the invention
The purpose of this utility model is to provide a kind of air suction type agricultural sprayer nozzle that can improve spraying droplet diameter, effectively reduce agricultural chemicals drift, flow-controllable.
The purpose of this utility model realizes like this, comprise feed tube joint and sprayer body, external screw thread is processed with outside feed tube joint, the longitudinal center line of feed tube joint and sprayer body liquid feeding end is processed with feed pathway, the longitudinal center line of sprayer body outlet end is processed with liquid spray orifice, liquid spray orifice and feed pathway junction are provided with gas-liquid mixed room, the feed pathway of sprayer body is provided with trunnion, in feed pathway between trunnion and gas-liquid mixed room, radial direction is provided with air port, air port is provided with throughput adjusting device.Described throughput adjusting device comprises air inlet, adjustment screw and spring, the sprayer body of air inlet processing outside air port is communicated with air port, adjustment screw radial direction is movably arranged on sprayer body, the conical plug coordinated with air port is processed in the end of adjustment screw not with nut one end, and spring housing is contained in outside adjustment screw.
The air suction type agricultural sprayer nozzle compact conformation of the flow-controllable that the utility model provides, reliable operation, spraying droplet diameter can not only be improved, effectively reduce agricultural chemicals drift, and the disease and pest different demands to different agricultural chemicals different according to crops can regulate spray value, save agricultural chemicals, avoid waste, there is high economy and practicality.

Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but limited the utility model never in any form, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in Figure 1, the air suction type agricultural sprayer nozzle of a kind of flow-controllable described in the utility model, comprise feed tube joint 2 and sprayer body 5, external screw thread is processed with outside feed tube joint 2, the longitudinal center line of feed tube joint 2 and sprayer body 5 liquid feeding end is processed with feed pathway 1, the longitudinal center line of sprayer body 5 outlet end is processed with liquid spray orifice 7, liquid spray orifice 7 and feed pathway 1 junction are provided with gas-liquid mixed room 6, the feed pathway 1 of sprayer body 5 is provided with trunnion 3, in feed pathway 1 between trunnion 3 and gas-liquid mixed room 6, radial direction is provided with air port 4, air port 4 is provided with throughput adjusting device.Described throughput adjusting device comprises air inlet 8, adjustment screw 9 and spring 10, air inlet 8 to be processed on the sprayer body 5 outside air port 4 and is communicated with air port 4, adjustment screw 9 radial direction is movably arranged on sprayer body 5, the conical plug coordinated with air port 4 is processed in the end of adjustment screw 9 not with nut one end, and spring 10 is sleeved on outside adjustment screw 9.
Further, described feed pathway 1 is provided with tapering transition section with junction, gas-liquid mixed room 6.
Further, arc transition is all processed into, to reduce fluid resistance in each expanding channels place of being processed with of feed tube joint 2 and sprayer body 5 inside and reducing place.
Further, for being threaded between described feed tube joint 2 and sprayer body 5, assembling for convenience detach.
As shown in Figure 2, during work, liquid enters into jet pipe by medicine-chest under the effect of nebulizer pressure, then enters shower nozzle feed pathway 1.At trunnion 3 place due to reduced cross-sectional, liquid flow velocity speeds, pressure drop, produces vacuum.The vacuum at trunnion 3 place makes air be drawn into below trunnion 3 by air inlet 8 and air port 4, and in gas-liquid mixed room 6, place mixes with liquid, and the droplet forming air bubble is abrim sprayed by the liquid spray orifice 7 of nozzle again.The droplet of ejection is owing to being mixed with a large amount of air bubbles, and fogdrop diameter increases, and tack strengthens, and reduces drift.The aperture of air port 4 is controlled by adjustment screw 9, thus controls to suck air capacity.When adjustment screw 9 is tightened inwards, air port 4 aperture reduces, and the air capacity of suction reduces, and correspondingly increases the ratio of gas-liquid mixture liquid; Otherwise when adjustment screw 9 is outwards back-outed, air port 4 aperture increases, the air capacity of suction increases, the corresponding minimizing of liquid ratio.Therefore, the air suction type agricultural sprayer nozzle of the utility model flow-controllable, not only effectively can reduce drift, but also can according to the different disease and pest of crops to the different demands of different agricultural chemicals, control spray value number, save agricultural chemicals, avoid waste.In addition, the air suction type agricultural sprayer nozzle compact conformation of the flow-controllable that the utility model provides, reliable operation, has high economy and practicality.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
