In the all-return type backhoe of the riding type, the boarding control unit provided on the swivel needs to be arranged so that the excavator can be seen well, and the engine and the excavator are weighed in the front-rear direction. It is necessary to provide a well-balanced structure, and for such a request, a boarding control unit is provided near the one side of the front half of the swivel base, and the base of the excavator is set near the other side of the swivel base. Generally, the engine is mounted in the second half. According to the basic arrangement configuration of the all-turning backhoe as described above, the smaller the aircraft is, the larger the proportion of the boarding maneuvering section on the turntable becomes, and the excavator has to be provided at a position far from the turning center. .. As a result, the turning space required to turn the excavator when it is folded and stored becomes larger as it exceeds the lateral width of the traveling vehicle body, and excavation work including turning cannot be performed in a small work site where the traveling body can enter. The excavation work was limited to the forward and backward movement. Further, the smaller the rut distance of the traveling device and the lower the stability of the machine body, the smaller the size of the machine is. The present invention has been made by paying attention to such an actual situation, and it is an object of the present invention to provide a small-sized backhoe of all-turning type which is capable of turning work in a narrow area and is also excellent in stability. is there.

As described above, according to the present invention, the excavation device can be stored near the center of the swivel base by removing the boarding maneuvering unit which occupies a large space on the swivel base for a small machine. As a result, the turning space can be accommodated within the width of the machine, and excavation work including all turns can be performed well even in a narrow work area. Moreover, since the user does not board the aircraft, it is now possible to safely perform work under adverse conditions in which the attitude of the aircraft is difficult to stabilize.
