CHEMICAL SCATTERING APPARATUS FOR RICE TRANSPLANTER

摘要

PROBLEM TO BE SOLVED: To provide a practical chemical scattering apparatus for a rice transplanter to deliver a powdery chemical stored in a chemical hopper with a delivery mechanism at a prescribed rate and scatter the delivered chemical with a diffusing mechanism and effective for the delivery of the chemical in high accuracy in a manner to enable easy change of the chemical scattering state with a simple structure. SOLUTION: The delivery mechanism 31 is provided with a single mesh plate 40 placed close to a chemical discharging port (a) at the lower end of the chemical hopper and having a plurality of delivery holes (b), a mesh plate driving mechanism 50 to reciprocate the mesh plate 40 and a plurality of right and left chemical dropping ports (c) to guide the chemical dropped from the delivery holes (b) to the diffusing mechanism 32.
