Adjustable and sliding chemical sprayer for rice field

Abstract

An adjustable push-pull agricultural chemical sprayer for killing the rice pests including plant hopper is composed of a hand pushed frame, a liquid chemical tank, the combined rod for spraying agricultural chemical, a quadrangular regulating frame, a liquid chemical pump and several turnable slide plate installed to the legs of hand pushed frame for sliding in rice field. Its advantages are high insecticiding effect and low residue of agricultural chemical in rice grains.

Description

Technical field: [0001] The invention relates to a pesticide sprayer, in particular to a rice sprayer. Background technique: [0002] During the growth of rice, it will be harmed by many diseases and insect pests. The damage parts of these diseases and insect pests on rice plants are different, especially the diseases and insect pests that harm the middle and lower parts of rice such as sheath blight and rice planthopper. Very difficult. In the mature stage of rice filling, the harm of rice planthoppers is particularly serious, often causing a substantial reduction or failure of rice production. In order to prevent and control rice planthoppers, the commonly used culling method is to spray the rice with a knapsack sprayer or a fog machine, and the sprayed liquid will slowly flow down the upper leaves of the rice, but the liquid will be stained by the upper leaves. Sticking a considerable part, therefore, can not fully reach the middle and lower part, the drug effect can no...

In the mature stage of rice filling, the harm of rice planthoppers is particularly serious, often causing a large reduction in rice yield or failure

In order to prevent and control rice planthoppers, the commonly used culling method is to spray the rice with a knapsack sprayer or a fog machine, and the sprayed liquid will slowly flow down the upper leaves of the rice, but the liquid will be stained by the upper leaves. Therefore, it cannot fully reach the middle and lower parts, and the drug effect cannot be fully exerted, and the control effect is poor. At the same time, the residual amount of pesticides in the rice grains increases, which affects the quality of rice.

Although the sprayer used is small and convenient, the labor intensity of the user is high, the safety is poor, and the liquid medicine is easy to drip on the operator, which often causes the operator to be poisoned.

In recent years, due to the increased damage of rice planthoppers, in order to effectively control rice planthoppers, people often use spraying after branching of rice plants. Once lodging, the yield will be reduced by 10%-30%, and the income of farmers will suffer huge losses
