SOIL DISINFECTING MACHINE

Japanese Patent JP3809480

B2

PROBLEM TO BE SOLVED: To provide a soil disinfecting machine prevented from inadvertently issuing a liquid chemical therefrom.
SOLUTION: This soil disinfecting machine 10, which works in such a way that a liquid chemical in a liquid chemical tank 18 is issued from an injection blade 19 by the action of a liquid chemical pump 15 driven by the rotation of a rolling wheel 14 on a machine frame 11, has the following construction: the inner circumferential surface of the rolling wheel 14 is provided with a tooth part 21 as a sequence of many recesses 21a and a check pawl 22 is erected on a sleigh 20 vertically movably attached to the machine frame 11 and adjoining to the rolling wheel 14. In carrying out a disinfecting work, the sleigh 20 is in contact with the ground and the check pawl 22 is not engaged on the tooth part 21, in contrast, when the rolling wheel 14 is lifted off the ground, the sleigh 20 descends by its own weight, resulting in engagement of the check pawl 22 on the recesses 21a of the tooth part 21 and checking the rolling wheel 14, thereby stopping issuing the liquid chemical.
