Abstract
The utility model provides a corona electrified blowing head. Cooperated with the blowing head, an automotive dusting machine and a large size agricultural medicine spread machine can become electrostatic powder blower medicines. The corona electrified blowing head can be widely used for spreading agricultural chemical powders for preventing pest and disease damages. Proved by tests, after the corona electrified blowing head is adopted on the powder blower medicines, the deposit rate of the agricultural chemical powers can be increased by 50-80%, and the deposit rate at the back side of a target drone can be increased at 4-5 times.
Description
The utility model relates to a kind of corona charging shower nozzle, and it belongs to the medicinal apparatus of a kind of agricultural chemicals.
On the domestic market hand gun duster and the multiple model of power-driven powder-spraying machine are arranged at present, dust main by air-flow disperse, powder is not charged, it is bigger to be affected by the external environment, the target deposition is low, environmental pollution is serious, makes this dispenser machinery and application technology be subjected to considerable restraint.Existing large-scale electrostatic dusting machinery is sold on the overseas market, as american documentation literature US3339840, but only is applicable to that large-scale agricultural machinery (as tractor) upward uses, the cost height, and the operating technology difficulty is big, does not meet China's national situation.
The purpose of this utility model is to provide a kind of electrostatic duster corona charging shower nozzle, and it and former non-electrostatic dusting machinery (as WFB-18AC), high pressure generator are combined into electrostatic dusting machinery.The utility model can make static on the powder band, and the agricultural chemicals deposition is improved greatly, and then increases substantially the agricultural chemicals availability, reduces the pollution of agricultural chemicals to environment.
Fig. 1 is a structure chart of the present utility model.
1, duff pipe mouthpiece, 2, center high pressure negative electrode, 3, the supplemantary electrode binding post, 4, supplemantary electrode, 5, flour extraction pipe, 6, high pressure generator, 7, shower nozzle.
Fig. 2 is a vertical view of the present utility model.
As shown in Figure 1, the utility model is made up of duff pipe mouthpiece 1, center high pressure negative electrode 2, supplemantary electrode 4 and flour extraction pipe 5 four big parts, center high pressure negative electrode 2 is fixed by screws on the duff pipe mouthpiece 1, and supplemantary electrode 4 links to each other with duff pipe mouthpiece 1, flour extraction pipe 5 by the screw thread of both sides. Duff pipe mouthpiece 1 another side of the present utility model links to each other by the pipe that dusts of screw thread and power duster tool, the caliber size of its mouthpiece can according to different model the existing facility that dust the jet pipe bore and change; Can fix a high pressure generator 6(by screw on the shell of the present utility model also can be fixed on the jet pipe of the former facility that dust), its power line is linked on the carbon electrode coil of power duster, high pressure negative output terminal (-) is attached on one group of center high pressure negative electrode 2, and high pressure positive output end (+) is attached on the supplemantary electrode 4 by supplemantary electrode binding post 3; Supplemantary electrode 4 is a ring-type conducting metal (such as copper etc.), links with duff pipe mouthpiece 1, flour extraction pipe 5 respectively by the screw thread of both sides, and by the distance between this threaded adjusting center high pressure negative electrode 2 and the supplemantary electrode 4. Mass data proves that the distance between center high pressure negative electrode 2 and supplemantary electrode 4 is that 0.5-4cm is good, and its best distance is 0.8-1.2cm. When the shower nozzle diameter can arrange a plurality of centers high pressure negative electrode greater than 2.5cm, the distance between the high pressure negative electrode of center is 1.0-1.5cm.
Be described in detail embodiments of the invention (the invention is not restricted to present embodiment) below in conjunction with accompanying drawing:
The utility model corona charging shower nozzle 7 is received the jet pipe front end of power-driven powder-spraying machine (Huairou, WFB18AC Beijing product); On the shell of duff pipe mouthpiece, fix a high pressure generator 6 by screw, its power line is linked on the carbon electrode coil of this power duster, high pressure negative output terminal (-) is attached to (distance of adjoining between the center high pressure negative electrode 2 is 1.2cm) on three center high pressure negative electrodes 2, and high pressure positive output end (+) is attached on the supplemantary electrode 4 by supplemantary electrode binding post 3; Supplemantary electrode 4 is a ring-type conductive material copper, and its screw thread by both sides links with duff pipe mouthpiece 1, flour extraction pipe 5 respectively, and to make the spacing between center high pressure negative electrode 2 and the supplemantary electrode 4 be 1.0cm by regulating this screw thread.Behind the gasoline engine of the motor-driven duster WFB18AC of starting, under powerful air-flow and pressure effect, pulvis is blown into the corona charging shower nozzle; The power line that passes through of magneto provides 6-9 volt voltage in high pressure generator 6 on the other hand, through boost, rectification, voltage stabilizing, it can produce the DC voltage of 5-20 kilovolt on high pressure center negative electrode 2 and supplemantary electrode 4.When the high pressure draught of band powder passes through central negative electrode 2 and supplemantary electrode 4, under the effect of electrostatic field, be with static, realize electrostatic dusting.
The utility model is compared than prior art has following remarkable advantage:
1, pollution is little.Because the electrostatic effect of charged powder makes that powder is easy to not run off attached on the target body, lack drift, thereby significantly reduced pollution environment.Because powder has electric charge, the deposition of target reverse side is 3-4 a times of non-static.
2, medication economizes.The raising of agricultural chemicals availability can reduce by 50% pesticide dosage during actual the use.
3, on target, cover evenly.Under effect of the present utility model, powder has identical electric charge, repels mutually in the directed movement process, so coacervation does not take place, covers evenly on target.
4, adsorb firmly on object owing to powder is charged, thereby powder loses less because of wind and weather after sprinkling.
5, the utility model is simple in structure, and is easy to maintenance.
