Description
Technical Field
The utility model relates to a spray head.
Background
Corn is the main grain crop in China, and the planting area is large. The growth period of the corn is generally 3-4 months, the period comprises three main physiological periods of emergence period, jointing period and heading period, and weeding, insect killing and the like are required in the growth period of the corn to prevent the occurrence of corn diseases and insect pests. At present, the most effective prevention and treatment measure for corn diseases and insect pests is pesticide spraying, high-concentration pesticide is diluted by water and then is sprayed out in a mist form by a spray head after being pressurized by high-pressure equipment, in order to form water mist, the size difference of a water inlet and a water outlet of the spray head is large usually, the water outlet is very small, so that the water outlet of the spray head is blocked very easily, and the spraying efficiency or uniformity is further influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that current pesticide shower nozzle easily blockked up, provide a pesticide shower nozzle for maize is planted.
The pesticide sprayer for planting the corn of the utility model consists of a main pipe body, a pipe cap and a cylindrical plug; the pipe cap is arranged at the water outlet end of the main pipe body, and a through hole is formed in the center of the pipe cap; the cylindrical plug is arranged in the main pipe body, and one end of the cylindrical plug extends out of the pipe cap from the through hole in the center of the pipe cap; a limiting circular plate with the diameter larger than that of the central through hole of the pipe cap is arranged at the end part of the cylindrical plug in the main pipe body, and a first spring is sleeved on the cylindrical plug between the pipe cap and the limiting circular plate; the diameter of the first spring is larger than the through hole in the center of the pipe cap; the cylinder stopper below is provided with the cylinder, and the cylinder upper end is provided with the arch, and the cover is equipped with the second spring in the arch, and the cylinder lower extreme passes through several connecting rod rigid coupling with being responsible for the internal wall of body.
The utility model discloses principle and beneficial effect do:
the utility model discloses be provided with pipe cap one end when the maize is planted and use pesticide shower nozzle for going out the water end, the other end is for intaking the end, and the end of intaking is connected the maize and is spouted the spray tube of medicine machine. High-pressure liquid medicine in the main pipe body is sprayed out from a gap between the cylindrical plug and the through hole in the center of the pipe cap to generate mist pesticide, when no sundries exist in the main pipe body, the spraying flow rate of the liquid medicine is constant, and meanwhile, the gap between the cylindrical plug and the through hole in the center of the pipe cap is kept unchanged. When sundries exist in the main pipe body and the sundries block the gap between the through hole in the center of the cylindrical plug and the pipe cap, the liquid medicine is blocked to be discharged, the instantaneous liquid medicine discharge pressure fluctuates, and meanwhile, the springs are arranged on the two sides of the cylindrical plug, so that the cylindrical plug can shift under the changed water pressure, the sundries existing in the shifting process and in the gap can be discharged to the outside of the spray head along with the springs, and the blockage is avoided. Therefore, the utility model discloses a delivery port of shower nozzle is difficult to take place to block up, has guaranteed to spout medicine efficiency and homogeneity.
