■ 3. Operation Next, the operation of the present embodiment will be described.
When the self-propelled soil improvement machine 1 is started and the raw soil S is put into the first hopper 4, the raw soil S is conveyed to the crushing unit 6 by the conveyor 41, and the soil improvement is performed from the second hopper 5 in the middle. Agent D is sprinkled from above.
Inside the crushing unit 6, the raw soil S is kneaded with the soil conditioner D by the soil cutter 61 and the rotary hammer 62, and is crushed to a predetermined particle size, and is carried out as product soil M by the carry-out conveyor 7.

At this time, since fine dust rises on the carry-out conveyor 7, this dust is collected by driving the fan 91 of the dust collector 9.
Dust on the carry-out conveyor 7 is taken in from the opening 933 on the lower surface of the filter box 932, and the dust is collected by the filter 95 mounted in the filter box 932.
At this time, since the filter 95 is formed in a slightly larger cylindrical shape than the cage 943, the inner space of the filter 95 becomes low pressure by the fan 91 and is deformed inside the cage 942 as shown in FIG. In this state, the dust F is collected in the recessed portion.

If the filter 95 is clogged with dust F during the operation of the dust collector 9, the air that has been pressurized to a predetermined pressure inside the header pipe 961 is opened by the control signal from the pilot valve box 962 and blown. Spray from the tube 963 to the filter mounting hole 941.
Then, as shown in FIG. 8, the inner space of the filter 95 becomes high pressure, and the filter 95 is deformed so as to expand to the outside of the cage 943. Thereby, the collected dust F drops from the filter 95 and is discharged onto the carry-out conveyor 7 from the opening 933 on the lower surface of the filter box 932.

Further, since the dust collector 9 is arranged so that the dust collector main body 92 and the fan 91 are juxtaposed, the length does not increase more than necessary even when the dust collector 9 is mounted on the carry-out conveyor 7. When transporting the soil-type soil conditioner 1 with a trailer or the like, it is not necessary to remove and transport the dust collector 9 regardless of the transport height restriction.

Further, since the dust collecting device 9 is provided on the carry-out conveyor 7 and is set to have a width dimension so as not to jump out to the outside in the width direction of the carry-out conveyor 7, the dust collection device 9 becomes an obstacle at the time of running and working. Furthermore, since the self-propelled soil conditioner 1 can be run with the dust collector 9 attached, the traveling performance of the self-propelled soil conditioner 1 is not impaired.
Moreover, since the fan 91 and the air blowing device 96 of the dust collector 9 are driven by the supply of pressure oil from the hydraulic pump, similarly to the drive portions of the respective parts of the self-propelled soil improvement machine 1, separately. The dust collector 9 and the air spray device 96 can be driven without preparing a power source.
