PROBLEM TO BE SOLVED: To provide a technology capable of mounting/dismounting a soil disinfector simply and independently without using an exclusive stand, whereas, in a conventional soil disinfector, a stay thereof is required to be mounted/dismounted with a pin, while being held on a position mountable on/dismountable from a hitch of a running vehicle, by lifting the soil disinfector or the like when being mounted on/dismounted from the running vehicle.SOLUTION: A chemical injection claw 16L of a soil disinfector has an extension mechanism 15L sliding vertically in a cylindrical support 44 provided in a machine body, for inserting and fixing a fixture 54 from a bearing hole thereof to adjustment holes 51a...51d, 52a, 52b of the chemical injection claw 16L, to thereby set so as to have a prescribed extension length L. The adjustment holes 51a...51d, 52a, 52b comprise a first adjustment hole group 51 for setting an injection depth, and a second adjustment hole group 52 for performing attitude control of the machine body in the state where the tip of the chemical injection claw 16L is allowed to abut on the ground 57, and the second adjustment hole group 52 is constituted so as to have a smaller diameter than the first adjustment hole group 51, on the lower side than the first adjustment hole group 51. |
