Abstract
The utility model relates to a wind driving ultramicro ejecting head for ultralight airplanes, which is characterized in that an atomizing cup, a screw propeller and a hollow shaft at one end of the ejecting head are organically combined into the integral structure and the outer part of the sealing ring of the other end of the ejecting head is provided with a pad ring with a concave groove and a sealing bowl to form a movable seal and a pressure relief apparatus. The wind driving ultramicro ejecting head overcomes the abrasion of the atomizing cup, which is caused by the friction torque transmission. Meanwhile, the wind driving ultramicro ejecting head waves away the medical liquid leaked from a sealing ring and ensures that a bearing has no corrosion any more. The utility model has small volume, light weight and small aerodynamic resistance, and can meet the requirements for drop sizes when various different medical agents, such as the insecticide, the germicide, the herbicide and the liquid fertilizer, are ejected.
Description
The utility model relates to atomising device, particularly relates to ultra light aircraft drives ultramicron with wind atomising device.
Along with the development of national economy and aeronautical technology, become the inexorable trend of agricultural plant protection technology development gradually with the aircraft prevention and elimination of disease and pests.The spray appliance of China's ultralight aircraft special use generally adopts fluid pressure type shower nozzle and electricity to drive shower nozzle, and the former atomizing effect is poor, and needs big pressure, and pump and system architecture are had higher requirement; The latter is because each shower nozzle needs a motor-driven, so weight, volume and resistance are bigger, have limited the quantity of shower nozzle, and atomizing effect is relatively poor.
The wind-driven spray appliance of external ultra light aircraft, nut is connected with elastic ring the screw of its shower nozzle one end with atomizing cup.It is by the friction power transmission, because soup often corrodes elastic ring and nut, therefore, the two can produce disengaging, and this harmful disengaging causes shower nozzle to lose efficacy and can gall atomizing cup.The other end of shower nozzle, soup (agricultural chemicals) tend to cannelure from the sealing ring and flow into and infilter bearing cavity corrosion bearing, cause the stuck back of serious corrosion of bearing even bearing enclose shower nozzle to lose efficacy.
The purpose of this utility model is to provide a kind of wind to drive the ultramicron shower nozzle, and it is a kind of with screw, the structure that feeding is bored, atomizing cup is combined integrated and the new type nozzle with movable sealing pressure relief device structure.
The technical solution of the utility model realizes as follows:
The utility model is made up of housing, hollow shaft, screw, atomizing cup, feeding awl;
The end face of shower nozzle one end atomizing cup has equidistant claw type boss more than 3, the end face of screw has corresponding equidistant groove more than 3, the endoporus of screw is connected by key with hollow shaft, makes atomizing cup, screw, hollow shaft organically consist of the structure of one.The shower nozzle other end is equipped with an obturating cup and has an end face that the pad of a cross groove is arranged in the outside of hollow shaft, promptly become movable sealing and pressure relief device.
Advantage of the present utility model is:
1. after the structure that atomizing cup, screw, hollow shaft are combined into one, overcome and to produce break-off between them when depending merely on the friction power transmission and cause the atomizing cup broken invalid.
2. after obturating cup and pad being housed on the hollow shaft, become movable sealing and pressure relief device, after a part of soup is by the cannelure on the hollow shaft inflow sealing-plug, can displaces and can not enter in the bearing bore, thereby guarantee a no longer corrosion of axle through the groove of packing ring.
3. the utility model is in light weight, volume is little, aerodynamic drag is little, in the time of satisfying various different medicament such as spraying insecticide, bactericide, herbicide and liquid fertilizer to the requirement of drop size.
Example in conjunction with the accompanying drawings, the utility model is described in further detail:
Fig. 1: wind drives ultramicron nozzle structure figure.
Fig. 2: movable sealing and pressure relief device figure.
In Fig. 1～2: collar (23), the outer collar (24) of bearing, location collar (25) in housing (1), flow dish (2), sealing-plug (3), pad (4), obturating cup (5), spring (6), hollow shaft (7), lining (8), elastic collar (9), packing ring (10), seal (11), screw (12), atomizing cup (13), nut (14), branch medicine screw (15), feeding awl (16), key (17), bearing (22), elastic ring (21), the bearing.
The end face of the atomizing cup (13) of shower nozzle one end has 4 2.5 * 2.5 claw type boss, the end of screw (12) and 4 corresponding 7.5 * 2.5 groove is arranged, the boss of atomizing cup (13) embeds in the groove of screw (12) and forms one, when screw (12) with make atomizing cup (13), screw (12), hollow shaft (7) composition one after hollow shaft (7) connects with key (17); When screw (12) is subjected to flying power to do the time spent, its turning moment directly drives atomizing cup (13) motion.
The other end of shower nozzle is equipped with a spirality obturating cup (5) and a pad (4) in the outside of hollow shaft (7), the end face of pad (4) has a criss-cross groove.
During spraying, the medicine source is transported to shower nozzle with soup, soup is through flow dish (2) and hollow shaft (7) ejection, forms as thin as a wafer soup curtain by the medicine feed of high speed rotating awl (16), the atomizing cup (13) of soup curtain through radial fine and closely woven teeth groove is arranged becomes strand superfine brin of thigh, under the air stream drives of the screw of shower nozzle (12) when aircraft flight, drive atomizing cup (13) and medicine feed awl (16) rotation at a high speed, under atomizing cup (13) centrifugal action that changes at a high speed, soup is atomized and sprays away.
When soup was flowed through hollow shaft (7), a part of soup can leak to the cannelure of sealing-plug (3) and reduce pressure, though cannelure can play certain sealing function because of decompression makes sealing-plug (3).Hollow shaft (7) is during by screw (12) driven rotary, because spiral obturating cup (5) is very small with the gap of hollow shaft (7), obturating cup (5) had played movable sealing when the medicine that air mass is come the leakage of sealing-plug (3) cannelure because of rotation drives in the spiral was rushed for pad (4), its soup is discharged by the groove on the packing ring (4) and is not entered in the bearing bore, thereby guarantees that bearing is not by corrosion.
Claims (1)
- A kind of ultra light aircraft drives the shower nozzle of ultramicron with wind, form by housing (1), atomizing cup (13), screw (12), hollow shaft (7), feeding awl (16), it is characterized in that: the end face of the atomizing cup (13) of shower nozzle one end has 3 equidistant boss at least, the end face of screw (12) has 3 corresponding equidistant grooves at least, and screw (12), hollow shaft (7) connect by key (17); There is an obturating cup (5) outside of the hollow shaft of the shower nozzle other end (7) and the pad (4) of a cross groove is arranged.
