Anti-drift knapsack spray device

Abstract

The invention discloses an anti-drift backpack type spraying device which comprises a water tank, a knapsack binding band arranged on the water tank and a water suction pipe arranged in the water tank, wherein the water suction pipe penetrates through the water tank in a sealing way, a spraying rod is communicated with a penetrating end, and the free end of the spraying rod is communicated with aspray head; the spray head comprises a flow dividing column, a vibration chamber, a spraying mechanism, wherein the spraying mechanism comprises a cylindrical joint, the joint is communicated with thevibration cavity, a plurality of flow guiding cavities are uniformly arranged through the joint, each flow guiding cavity comprises an inverted round table cavity and a cylindrical cavity which are arranged along the direction far away from the joint, wherein the bottom end of the cylindrical cavity is coaxially communicated with a flow guiding pipe, each flow guiding pipe is connected with a blow pipe, a steel wire for rolling the blow pipe is arranged on the blow pipe; mist outlet holes are formed on the flow guiding pipe and the blow pipe at intervals. The anti-drift backpack type sprayingdevice has the advantages of reducing the spraying granularity of the spraying liquid, increasing the plant absorption effect and reducing the drift loss caused by the reduction of the spraying granularity.

Description

technical field [0001] The present invention relates to the field of nebulizer devices. More specifically, the present invention relates to an anti-drift knapsack spray device. Background technique [0002] At present, in order to remove the damage caused by foliar diseases and insect pests to crops, crops need to use insecticides, insecticides and herbicides for spraying operations. For traditional small-scale family planting, knapsack sprayers are often used, and knapsack sprayers have the following problems. : [0003] First, because the operator directly relies on the operator's arm to shake the operating handle up and down to pressurize and spray the liquid medicine, the operator is very prone to fatigue, resulting in uneven pressure during spraying; [0004] Second, the particle size of the spray nozzle is too large to cause poor absorption, which directly affects the spray effect. Although the existing nozzle can provide small particle spray effect, first of all, it...

AI Technical Summary

Problems solved by technology

[0003] First, because the operator directly relies on the operator's arm to shake the operating handle up and down to pressurize and spray the liquid medicine, the operator is very prone to fatigue, resulting in uneven pressure during spraying;

[0004] Second, the particle size of the spray nozzle is too large to cause poor absorption, which directly affects the spray effect. Although the existing nozzle can provide small particle spray effect, first of all, its structure is too complicated and not suitable for traditional small-scale family planting, and the particles Too small will cause the spraying liquid to be easily affected by wind force during the spraying process, resulting in drifting and reducing the utilization rate of pesticides
