A movable drug mixer

Abstract

The invention discloses a moveable chemical mixer. The chemical mixer comprises a drug bag, a shrinkage section, an expansion section, a leaking screen and a spiral organ; the spiral shrinkage section is in threaded connection with the expansion section, and the leaking screen is adaptively connected with the shrinkage section and the expansion section; the spiral organ is arranged in the expansion section and in threaded connection with the expansion section; both ends of the drug bag are in threaded connection with the shrinkage section and the expansion section. By adopting the chemical mixer, pesticide is integrated to the mixer, so that the online mixing is realized, the mechanical structure is simplified, flowing path of the pesticide is greatly reduced, pesticide pollution to agricultural implements are reduced, and environment is protected; besides, the mixing efficiency of the chemical mixer is improved.

Description

technical field [0001] The invention relates to a pesticide mixer for spraying pesticides, in particular to a movable pesticide mixer. Background technique [0002] Pesticide online mixing This kind of mixing technology focuses on environmental protection and operator safety. The use of pesticides is controlled online through the mixer, which greatly reduces the harm of pesticides to operators and reduces the pollution to the environment and surrounding non-target organisms. And the spray device is more convenient to clean after application, it can be disassembled, recycled and refurbished or disposed of safely and worry-free for a long time. [0003] At present, there are many researches on online drug mixers, and some achievements have been made, but there are still some problems. For example, the sprayer uses a synchronous injection mixer (patent number 200910101373.7). This patent provides a driving signal from the engine to simultaneously inject the pesticide mother li...

AI Technical Summary

Problems solved by technology

However, the problem of synchronous injection type drug mixers for sprayers has not been solved, and the screw unit is composed of 3-5 pieces of screw blades, and the screw blades are rectangular plates with a length ratio of 1 or 1.25 and a thickness of 1-3 mm twisted 180° Forming, the connection relationship between one end of the helical blade and the other end of the helical blade is a 90° cross-welding. Although the mixing effect is good, the resistance is too large, which directly affects the spraying effect of the pesticide, and the practicability is not good.

A vehicle-mounted drug mixing device (Patent No. 201210585002.2), a design method of a jet drug mixer with a high mixing ratio (Patent No. 201410420915.8), these patents did not solve the problem of synchronous injection drug mixer
