AI Technical Summary

Technical Problem

Existing sprayers are prone to clogging nozzles when impurities are mixed into the pesticide solution, resulting in uneven pesticide application and waste. Current technology has not effectively solved the problems of pesticide sedimentation and clogging by undissolved particles.

Method used

It adopts a structure of filter tube, drive assembly, rotating rod and rubber scraper. The drive assembly drives the rotating rod and rubber scraper to scrape the inner wall of the filter cartridge to avoid clogging by undissolved drugs. At the same time, a conveying assembly is set up to deliver the drug solution to the spray nozzle.

Benefits of technology

It achieves uniform filtration and delivery of the liquid medicine, avoids nozzle clogging, ensures uniform spraying of the liquid medicine, and reduces waste of the medicine.

Abstract

This utility model relates to the field of pesticide spraying technology, specifically disclosing a pesticide spraying machine that dispenses pesticide evenly. It includes a mixing chamber, a filter tube, and a base plate. The filter tube contains a processing component for filtering the pesticide solution. This processing component includes a filter cylinder and a rotating rod. The filter cylinder is snapped into the filter tube, and the rotating rod is rotatably mounted inside the filter cylinder. A cylinder cover is installed on the top of the filter tube, and the rotating rod is rotatably connected to the cylinder cover. This utility model, by incorporating a filter tube, a driving component, a rotating rod, a filter cylinder, rubber scrapers, and a driven wheel, allows the driving component to rotate the driven wheel, which in turn rotates the rotating rod. The rotating rod then drives several sets of rubber scrapers to scrape the inner wall of the filter cylinder, preventing undissolved pesticide from clogging the filter holes and avoiding the accumulation of undissolved pesticide in the spray nozzles, thus preventing waste.
