  At this time, in the mixing tank 24 of the mixing apparatus 23, two rotating shafts (not shown) provided with a plurality of paddles are rotating, and the earth and sand supplied to the mixing tank 24 and the soil quality improving material Are mixed with stirring. Thereby, the improved soil in which the earth and sand and the soil conditioner are appropriately mixed is generated in the mixing tank 24, and the improved soil falls from the mixing tank 24 onto the belt 25 </ b> B of the discharge conveyor 25, and the discharge conveyor 25. Is discharged to the outside of the soil improvement machine 1.

  When the soil improvement machine 1 is in operation, as shown in FIG. 7, an operator who puts soil into the hopper 14 using the hydraulic excavator 32 is moved from the cab 32 </ b> A of the hydraulic excavator 32 to the lower side of the hopper 14. The left and right indicator lamps 26 and 27 and the rear indicator lamp 28 provided can be surely visually observed.

  For example, when none of the yellow lamps 26A, 27A, 28A and the red lamps 26B, 27B, 28B of the indicator lamps 26, 27, 28 are lit, the earth and sand by the mixing device 23 and the soil quality improving material Since the mixing operation is performed smoothly, the operator can operate the hydraulic excavator 32 to continuously put earth and sand into the hopper 14.

  On the other hand, for example, when the yellow lights 26A, 27A, 28A of the indicator lights 26, 27, 28 are lit, it indicates that the load acting on the mixing device 23 exceeds a preset value. By temporarily stopping the introduction of earth and sand into the hopper 14, it is possible to prevent an excessive load from acting on the mixing device 23.

  Further, for example, when the yellow lamps 26A, 27A, 28A and the red lamps 26B, 27B, 28B of the indicator lamps 26, 27, 28 are turned on, this indicates that an excessive load is acting on the mixing device 23. The operator can get off the hydraulic excavator 32 and operate the operation panel 13 of the soil improvement machine 1 to quickly stop the operation of the mixing device 23 and protect the mixing device 23.

  Thus, according to the present embodiment, the left and right indicator lamps 26 and 27 and the rear indicator lamp 28 are arranged below the hopper 14, so that as shown in FIG. When the soil and sand are put into the hopper 14 of the soil improvement machine 1 using 32, the worker who has entered the cab 32A of the excavator 32 visually observes the indicator lamps 26, 27 and 28 at close positions. be able to. Thereby, the operator who operates the excavator 32 can surely check the lighting state of any one of the left indicator lamp 26, the right indicator lamp 27, and the rear indicator lamp 28, and the operation state of the mixing device 23 can be determined. It can be accurately grasped. As a result, according to the operation state of the mixing device 23, the amount of earth and sand introduced into the hopper 14 can be appropriately adjusted, and workability when generating the improved soil using the soil improvement machine 1 can be improved. . Further, by preventing an excessive load from acting on the mixing device 23, the mixing device 23 and the like can be protected.

  Further, the left and right indicator lamps 26 and 27 and the rear indicator lamp 28 are arranged at positions hidden under the funnel-shaped peripheral wall surface 15 constituting the hopper 14 when the hopper 14 is projected from above. Therefore, when the earth and sand are put into the hopper 14 using the hydraulic excavator 32, it is possible to suppress the earth and sand from colliding with the indicator lights 26, 27, and 28. As a result, each of the indicator lamps 26, 27, 28 can be protected from earth and sand, and the operation state of the mixing device 23 can be accurately notified over a long period of time by these indicator lamps 26, 27, 28. In addition, since it is not necessary to separately provide covers for protecting the indicator lamps 26, 27, 28 from the earth and sand that is thrown in, it is possible to contribute to a reduction in the number of parts.

  Further, the right indicator lamp 27 is arranged at a position where the line of sight L of the worker M reaches when the worker M operates the operation panel 13 of the soil improvement machine 1 as shown in FIG. As a result, not only when the operator operates the hydraulic excavator 32 but also when operating the operation panel 13 of the soil improvement machine 1, the operating state of the mixing device 23 is accurately determined by observing the right indicator lamp 27. I can grasp it.
