SOIL DISINFECTOR

PROBLEM TO BE SOLVED: To settle the problem that a conventional soil disinfector, which is attached to a traction traveling vehicle and injects chemicals into the soil with chemical injecting claws, is required to have a small size to be usable in the narrow field such as an agricultural greenhouse, but, when shortening the machine body longitudinal length by setting the travelling wheel mark erasing element near the chemical injecting claws, a large solid furrow is caused by the mark erasing element and the right behind chemical injecting claws, and the soil disinfection and insecticide effects are much decreased. SOLUTION: A first chemical injection claw 16 of chemical injecting claws 16, 17 and positioned right behind travelling wheels 61L, 61R includes a claw body 54 keeping a front obliquely downward inclining posture in the advancing direction F, a claw blade 55 and a chemical nozzle 57 are respectively set at a front surface 54F and a rear surface 54B of the claw body 54, and, on at least one of right and left surfaces 54L, 54R of the claw body 54, soil removing plates 58R, 58L capable of guiding the harrowed soil of the claw blade 55 to the soil surface 30a is equipped.
