The utility model relates to sweet potato planting technical field especially relates to a
medicine spraying device for sweet potato planting. The device includes support baseplate, and one end top surface of support baseplate is welded with
handle, and the top surface fixed connection of support baseplate has the
liquid storage tank, and the top surface of
liquid storage tank is equipped with inlet, and the side of
liquid storage tank is equipped with observation hole, and the other end top surface center position of support baseplate is equipped with limit sliding slot. The utility model discloses the rotation movement of stirring shaft is transmitted to eccentric shaft through the gear meshing structure, and after the conversion
circular motion, limit axle is pushed along the sliding groove reciprocating linear sliding through the rotary link, and through the linkage connecting rod of limit axle, power is transmitted to support pivot through the connecting plate, finally drives the rotation of the flow dividing platform, realizes the automatic reciprocating swing of the spray angle of atomizing
nozzle, effectively expands the contact area of liquid
medicine and sweet potato
plant, can guarantee the uniformity of spraying at the same time, significantly expands the spraying range, and improves the
pesticide application efficiency.
