DEVICE FOR SPRAYING AGROCHEMICAL

摘要

PROBLEM TO BE SOLVED: To provide a device for spraying an agrochemical, capable of preventing the pile and attachment of powdery agrochemical at the bottom part of a duct around the putting-in port when spraying the powdery agrochemical by a method for spraying the agrochemical by putting it in the duct so as to reduce its using amount by spraying the agrochemical without waste. SOLUTION: This device for spraying the agrochemical 1 equipped with a tubular body 2 installed with a powdery agrochemical-dispersing means 3 and an agrochemical-weighing means 4 for weighing the agrochemical by a prescribed amount each and putting it into the inside of the tubular body 2 is provided with that the powdery agrochemical-dispersing means 3 is fixed at the lower part 2d of the peripheral edge of an opening part 2b which is the one end of entrance side of wind sent into the inside of duct of the tubular body 2, and consists of a string-formed material 3a having a longer length than that of the tubular body extending to the opening part 2a side which is an exit side of the wind and a plate-formed body 3b attached at the terminal of the string-formed body 3a.
