Abstract:
     It works on the principle of the gravity of human body. In operation the operator puts on a pair of pumping boots. When a feet steps on the ground the pumping boot pumps air out while a feet takes off the ground the pumping boot sucks air in. Therefore when the operator walks forward the alternative pumping and sucking will take place, resulting from the alternative steping on and taking off the ground of two boots. The liquid chemicals in a tank will spray out through the air pressure. If the body weight is 50 kg the pressure to the liquid level may reach 50 atm. Thus the sprayer has high spray efficiency and long spray distance, and it is suitable for killing insects in large area crop.
