The specific embodiment:
At first, in order to improve air curtain wind speed uniformity, realize low volume, reduce float of mist droplet, design philosophy of the present invention is to change gas to get into the jet inertia effect in the air duct.Be used for air inlet of its surface arrangement of air duct and a plurality of linearly aligned exhaust vent 5 that wind helps technology; In order to change the inertia effect of jet; The present invention installs a slice ellipsoid arc grid deflector 1 below the inner air inlet of air duct; Ellipsoid arc grid deflector is the ellipsoid arcuation, and ellipsoid arc grid deflector 1 both sides tilt to be bowed downward to arcuation gradually along the air duct length direction; Ellipsoid arc grid deflector thickness is 1mm to 3mm, preferentially selects 2mm for use; Ellipsoid arc grid deflector is made up of a plurality of hollow grid bars, and hollow grid bar begins to be distributed on the ellipsoid arc grid deflector along the air duct length direction from ellipsoid arc grid deflector center, both sides hollow grid bar symmetry.Along circumferentially being uniformly distributed with 4 rectangle thin slice links 7, link is fixed on the blower fan retainer plate at air inlet place with clip 3 through welding or bolt connecting mode ellipsoid arc grid deflector through welding manner.The grid distance of ellipsoid arc grid deflector is between 2cm to 6cm, and excessive grid distance causes the guide performance of air-flow poor, and too small grid distance causes the air-flow back pressure excessive, influences the air duct muzzle velocity.Usually, grid distance is preferentially selected 4cm for use.In order to increase radiating effect, the thickness of ellipsoid arc grid deflector is even basically, and its value is selected 1 to 3mm scope for use, preferentially selects 2mm for use, and the material selection metal alloy is like stainless steel.Gas quickens laggardly to go into air duct when inner through wind speed, because inertia is concentrated and impacted on ellipsoid arc grid deflector; Part is through the airflow fence glazing bar of ellipsoid arc grid deflector then; A part has promptly changed the inertia effect of jet because the drag effect of this deflector flows to side in addition, arrives the outlet opening position of air duct equably; Pass through venthole accelerating jetting chimney fan at last, form uniform air curtain at the air duct length direction.
Below through accompanying drawing and practical implementation the present invention is carried out detailed explanation.
The use that matches of the present invention and boom sprayer, as shown in Figure 1, boom sprayer connects use with 11 suspensions of the wheeled tractor with rearmounted power output shaft.Air-flow assist type boom sprayer comprises frame 12, be installed on the frame 12 medicine-chest 15, spray pump, blower fan 13 and wind help the parts such as air-flow accessory system, spray boom 14 and medicine liquid spray system (shower nozzle) 16, hydraulic system of air duct 4 to form.
The course of work of air-flow assist type boom sprayer is following: after tractor 11 starts, drive hydraulic pump through power output shaft, spray boom developping solution cylinder pressure launches spray boom 14, and the tractor driver adjusts spray boom 14 height according to plant height through lifting hydraulic cylinder.There is an air duct 4 shower nozzle 16 back at linear distribution along whole frame length, and there is row's exhaust vent 5 bottom of air duct along frame, in spraying machine spraying operation, form air curtain.The wind-force of air duct is supplied with by hydraulically powered aerofoil fan, and wind speed can steplessly be adjusted.When environmental condition does not need wind to help, can close fan, carry out the routine spraying.At extraneous natural wind hour, the air curtain that air duct forms can stop droplet because effect of inertia drift backward, thereby can improve the operating speed of machine.Higher when extraneous wind speed, in the time of possibly causing drift, suitably adjust the angle and the wind speed of air curtain, to stop drift or to reduce the drift amount. in addition, the wind of the air duct droplet that the height place of 30cm and shower nozzle produce below shower nozzle greatly meets, and droplet is had acceleration.The speed of droplet has very big influence to the drift performance, so need on the air duct length direction, keep the uniformity of wind speed in the operation process, otherwise can cause formulation rate inconsistent.Because air curtain directly blows to plant leaf surface, leaf is had inverting action simultaneously, help the leaf back side and adhere to droplet, this is very important for eliminating those insects that colonize in the leaf back side.
In Fig. 2 a, Fig. 2 b, the present invention has added a slice ellipsoid arc grid deflector 1 at the corresponding back segment of the inner air inlet of air duct, and the appearance profile of ellipsoid arc grid deflector is oval camber, and hollow grid bar 6 is distributed on the deflector along the air duct length direction.Gas quickens laggardly to go into air duct when inner through hydraulically powered axial flow blower 13, because inertia is concentrated and impacted on ellipsoid arc grid deflector 1; Part is through the hollow grid bar 6 of ellipsoid arc grid deflector 1 then; A part has promptly changed the inertia effect of jet because the drag effect of this deflector flows to side in addition, arrives the outlet opening position of air duct equably; Pass through venthole accelerating jetting chimney fan at last, form uniform air curtain at the air duct length direction.The ellipsoid arc grid deflector 1 related grid type radiator structure of patent of the present invention design has increased the area of dissipation with cold wind, the high temperature hydraulic oil the grid chamber in can be fully and greatly the cold air of air quantity carry out heat exchange, thereby have good heat-radiation effect.
Fig. 3 a, Fig. 3 b, Fig. 3 c have provided the three-view diagram of ellipsoid arc grid deflector.
What should explain at last is: above embodiment only be used to explain patent of the present invention and and the described technical scheme of unrestricted patent of the present invention; Therefore, to the greatest extent this specification has carried out detailed explanation with reference to each above-mentioned embodiment to patent of the present invention, and still, those of ordinary skill in the art is according to the understanding of oneself, still can make amendment or is equal to replacement patent of the present invention; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of patent of the present invention, and it all should be encompassed in the claim scope of patent of the present invention.
