Anti-drip inner spiral controllable pressure sprinkler

Abstract

The invention relates to an anti-drip internal spiral controllable pressure spray head, which sequentially comprises a stop valve, a pipeline for pressure regulation and an internal spiral pressure spray head. The inner side of the end of the inner spiral pressure nozzle is a conical inner cavity, and several guide vanes are spirally distributed on the wall of the conical inner cavity, and the helical pitch between the spiral guide vanes gradually narrows to the center nozzle; and in the conical inner cavity The middle sleeve has a conical adjustment pressure block. The invention has the advantages of simple structure and convenient use, and can effectively solve the problem of pesticide dripping at the spray head when the pressure is reduced. In terms of structural design, the working principle of the check valve and the existing nozzle are combined, and a controllable device is added to adapt to different pressure types of drug pumps. The nozzle body is designed according to the principle of rotation, and pressure is applied to achieve faster rotation speed and better atomization effect.

Description

technical field [0001] The invention belongs to the technical field of plant protection machinery accessories, and in particular relates to an anti-drip internal spiral controllable pressure spray head. Background technique [0002] At present, domestic plant protection nozzles are still produced based on traditional design methods and manufacturing methods, and their sealing performance is not very good. The remaining drug solution is dripped. It not only causes waste of liquid medicine and increases the cost of medicine, but also drips and leaks when the sprayer completes the work and leaves the work area, causing environmental pollution and even endangering the lives of people or livestock. [0003] However, imported anti-drip nozzles are expensive, mostly made of plastic, easy to age, have a high probability of damage during the action of the spray rack, frequent replacement, and high cost of use. Contents of the invention [0004] The object of the present invention...
