Drip irrigation device with pesticide spraying function

Abstract

The invention relates to a drip irrigation device with a pesticide spraying function. The drip irrigation device comprises a pressurizing station, a plurality of adjustable nozzles and a pipeline, wherein the adjustable nozzles are mounted on the pipeline, and the pipeline is connected with the pressurizing station; each adjustable nozzle comprises a water pipe, a nozzle pipe and a nozzle cap, theadjustable nozzle is mounted on the pipeline through the water pipe, the nozzle pipe is mounted on the water pipe and communicated with the water pipe, the inner diameter of the nozzle pipe is smaller than that of the water pipe, one end, connected with the nozzle cap, of the nozzle pipe is conical, the lateral wall of the nozzle pipe is provided with an outer thread, one end, connected with thenozzle pipe, of the nozzle cap is a stepped cavity, the first-step cavity is conical and is coordinated with the conical end of the nozzle pipe, the inner wall of the second-step cavity is provided with an inner thread coordinated with the outer thread, and a nozzle body of a flared structure is arranged in the middle of the nozzle cap.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a drip irrigation device with the function of spraying medicine. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Drip irrigation is currently the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to more than double the fertilizer efficiency. It is suitable for irrigation of fruit trees, vegetables, commercial crops an...

AI Technical Summary

Problems solved by technology

Applying foliar fertilizer or foliar spray to kill insects generally requires another spray device, which increases the input cost

In addition, the existing pesticide spraying devices generally spray from top to bottom, and the pesticide spray is generally sprayed on the upper part of the leaf surface, but cannot be sprayed on the lower part of the leaf surface, which affects the insecticidal effect.
