2. Description of the Related Art Conventionally, a motor grader or the like has been used to spread and spread a laying material such as roadbed material such as crushed stone or gravel or asphalt material on the ground such as a site such as a road or a building or a plaza. It is constructed using a leveling work machine such as a finisher. The motor grader operates a number of blades mounted on the lower abdomen of the machine to operate an operating lever, which allows a dump truck to pre-press and evenly lay a pile of laying objects on a road surface at a predetermined interval. We perform leveling work rather than doing it. In addition, the finisher accommodates the laying object in a hopper installed in front of the traveling machine body, drops the laying object on the ground while sending the laying material backward with a conveyor equipped in the lower part of the machine, and is installed so as to be able to move up and down at the rear part of the machine body.

The hydraulic cylinder 30 is used for the leveling operation lever 1 installed in the driver's seat 11.
The leveling member 3 can be adjusted up and down by operating 5, and the manual leveling work is prioritized over the operation by the automatic control so that it can be operated at any time.

The structure and mode of each device will be described in detail below. As shown in FIG. 4, the leveling device 2 has a push roller 23 that can be pressed against the rear wheel of the transport vehicle 6 such as a dump truck in front of the front wall 2a that is tilted forward, and can be attached and detached via the mounting arm 23a. It is mounted so that the transport vehicle 6 is pushed and moved by the forward movement of the working machine 1 via the rollers 23. Further, on the back surface of the substantially vertical rear wall 2b, a plate-shaped leveling member 3 capable of projecting downward along the lower end of the discharge port 22 is vertically slid in guide grooves 24, 24 formed at both ends thereof.

The machine 1 is started to start the work. As a result, the personal computer 40 compares the sent current position data with the construction plan data, sends the control data to the control device 4, and the control device 4 sends the sent control data and
Based on the cylinder stroke of the hydraulic cylinder 30 detected by the position sensor 31, the inclination sensor 8 and the gradient of the leveling member 3, the operation amount of the left and right hydraulic cylinders 30, 30 is commanded to be determined, and each hydraulic cylinder 30 is operated in a predetermined manner. Then, the positioning of the leveling member 3 is controlled to smoothly perform the leveling work adapted to the construction plan data and the road surface condition.

The leveling work is performed as shown in FIG. 8 which schematically shows the positions of the leveling member 3 and the mirror 7 associated with the traveling work of the working machine 1, so that the work plan data can be obtained. It is done accurately. That is, work points D1 and D
2 ... D7 indicates each current position of the mirror 7 with respect to the design roadbed height 0 where the leveling member 3 is in accordance with the construction plan data, and the automatic tracking device 5 causes each mirror of the working points D1 to D2 as the working machine 1 advances. 7 When the height is detected and the lower end of the leveling member 3 is higher than the designed roadbed height of 0-Z1 or -Z2 height, this value is sent to the personal computer 40 and the control device 4 controls the hydraulic cylinder 30 to- The leveling member 3 is operated by lowering the Z1 and -Z2 values.
Is lowered so that the design roadbed height is 0, and the working point D

Further, when the leveling member 3 is + Z5 which is lowered below the design roadbed 0 as shown at the working point D5, the hydraulic cylinder 30 is moved up by + Z5 value to operate the leveling member 3 according to the construction plan data. The height of the designed roadbed is increased to 0, and the leveling control is performed as shown at work points D6 and D7 to continuously perform good leveling work. Further, at this time, when the inclination sensor 8 detects the inclination of the machine body or the inclination of the leveling member 3, the detected value is sent to the personal computer 40 through the control device 4 and the one hydraulic cylinder 30 is corrected by the correction difference as described above. Good construction is performed by moving the same and tilting the leveling member 3 as shown in FIGS. 7 (B) and (C).

As described above, the leveling work machine provided with the leveling device 2 according to the present invention can be easily operated without the need for skill, unlike the conventional leveling machine, and the leveling work can be performed with high accuracy. Can be done well. Further, according to the control system of the leveling member 3 having the above-described configuration, even when the specifications such as the construction plan data designed in advance at the time of construction are not input into the personal computer 40, the automatic tracking device 5 is laid out. By setting the construction site at a measurable point, measuring each point with the automatic tracking device 5, and inputting the local data to the personal computer 40, the construction plan data can be promptly and accurately prepared at the construction site. It is possible to perform the work based on the manual construction plan data separately from the construction plan data based on the construction specification, and it is possible to efficiently perform the work at any time. In this case, the personal computer 40 configured to be detachably installed in the machine body is detached and moved to the automatic tracking device 5 side or a desired place so that the input can be conveniently performed.
