Abstract
The utility model provides a manually operating electrostatic powder blower and a spray head with corona effect. The manually operating electrostatic powder blower can be widely used to spread agricultural chemical powders for preventing pest and disease damages. Proved by tests, after the utility model is adopted for spreading agricultural chemical powders, the deposit rate can be increased by 50-80%, and the deposit rate of the back side of a target drone can be increased by 4-5 times.
Description
The utility model relates to a kind of manual electrostatic duster and corona charging shower nozzle thereof, 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, this dispenser machinery and technology is used 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 manual electrostatic duster and corona charging shower nozzle thereof, and 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 the manual electrostatic duster structure chart of the utility model.
1, crank, 2, explosive barrel, 3, handle, 4, dc source, 5, high pressure generator, 6, shower nozzle, 7, duff pipe.
Above-mentioned dc source 4, high pressure generator 5 and handle 3 are fixed on the duff pipe 7 by screw, and by wire bond, shower nozzle 6 directly inserts or links to each other with duff pipe 7 by screw thread between dc source 4 and the high pressure generator 5.Explosive barrel 2 and duff pipe 7 can cast solids, but also split casting to each other by threaded connection or will duff pipe 7 directly insert in the medicine-chests 2 and fuse.
Fig. 2 is corona charging nozzle structure figure of the present utility model.
11, duff pipe mouthpiece, 12, center high pressure negative electrode, 13, the supplemantary electrode binding post, 14, supplemantary electrode, 15, flour extraction pipe.
Fig. 3 is a vertical view of the present utility model.
As shown in Figure 1 and Figure 2, the duff pipe mouthpiece 11 of the utility model corona charging shower nozzle 6 links to each other with the duff pipe 7 of hand gun duster by screw thread, the caliber size of its mouthpiece can according to different model existing hand gun duster the duff pipe bore and change; High pressure generator 5 high pressure negative output terminals (-) are attached on the group switching centre high pressure negative electrode 12, and high pressure positive output end (+) is attached on the supplemantary electrode 14 by supplemantary electrode binding post 13; Supplemantary electrode 14 is a ring-type conducting metal (as a copper etc.), links with duff pipe mouthpiece 11, flour extraction pipe 15 respectively by the screw thread of both sides.Great number tested data proves that the distance between center high pressure negative electrode 12 and supplemantary electrode 14 is that 0.5-4cm is good, and its optimum distance is 0.8-1.2cm.When the shower nozzle diameter can be provided with 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 6 is received the front end of the duff pipe 7 of hand gun duster; On the shell of duff pipe 7 by screw fixedly dc source 4, high pressure generator 5, handle 3, the power line of high pressure generator 5 is linked to dc source 4(and is made up of battery) on, the high pressure negative output terminal (one) of high pressure generator 5 is attached on the (see figure 2) center high pressure negative electrode 12, and high pressure positive output end (+) is attached on the supplemantary electrode 14 by supplemantary electrode binding post 13; Supplemantary electrode 14 is a ring-type conductive material copper, and it links with duff pipe mouthpiece 11, flour extraction pipe 15 respectively by the screw thread of both sides.Behind hand crank, under powerful air-flow and pressure effect, pulvis is blown into corona charging shower nozzle 6; The power line that passes through of dc source provides 6-12 volt voltage in high pressure generator 5 on the other hand, through its rectification, boost, rectification, it can produce the DC voltage of 5-15 kilovolt on high pressure center negative electrode 12 and supplemantary electrode 14.When the high pressure draught of band powder passes through central negative electrode 12 and supplemantary electrode 14, 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 so that powder is easy to be attached on the target body, does not run off, the mistake of wafing less, thus greatly reduced pollution to environment. Because powder is with electric charge, the deposition of target reverse side is 3-4 times of non-static.
2, medication economizes. The raising of agricultural chemicals utilization rate can reduce by 50% pesticide dosage during actual the use.
3, cover evenly at target, under effect of the present utility model, powder repels in the directed movement process mutually with identical electric charge, so do not condense phenomenon, covers evenly at target.
4, because powder is charged in the absorption of target thing firmly, thereby powder loses less because of wind and weather after sprinkling.
5, the utility model is simple in structure, and is easy to maintenance.
