The mounting frame 3 and the machine frame 4 are not raised or lowered, and the traveling machine body 1 can be continuously rotated to perform the forming operation continuously, thereby improving the work efficiency. And the penetration groove S is formed continuously, It can be improved drainage and breathable P.

  In this case, since the formation body 28 capable of forming the underdrain H in the field P soil W is disposed at the lower end of the penetration beam 6, the formation body 28 penetrates as the traveling machine body 1 advances Q. A culvert H can be formed in the trace groove S, and the drainage and air permeability of the field P can be improved due to the presence of the longitudinal channel T and the culvert H. In this case, the penetration beam 6 of the penetration beam 6 can be improved. Since the housing 30 is disposed at the lower end, the penetration of the penetration beam 6 into the soil W can be improved, and the penetration trace groove S can be formed smoothly.

  In this case, the pivot mechanism 5 is provided with the turning longitudinal axes 5a and 5b for connecting the mounting frame 3 and the machine frame 4 so as to freely turn in the horizontal direction E. Therefore, as shown in FIGS. The mounting frame 3 and the machine frame 4 can be easily connected and the structure can be simplified. In this case, the no-load posture of the machine frame 4 is shown in FIG. Since the posture holding mechanism 25 that can be held in the straight traveling direction is provided, it is possible to hold the no-load posture of the machine frame 4 in the straight running direction in a non-longitudinal path forming work state or the like. When the machine frame 4 is lifted away from the field P surface and the machine frame 4 is in a free state, it is possible to suppress unintentional left-right swinging around the center position of the machine frame 4 as the straight traveling direction. In this case, as the posture holding mechanism 25, the mounting frame 3 Since the pair of left and right posture holding springs 25a and 25a are installed between the machine frame 4, the structure of the posture holding mechanism 25 can be simplified and the machine frame 4 can be swung in the left and right directions. In this case, one of the pair of left and right posture holding springs 25a and 25a forcibly causes the posture of the machine casing 4 to be restored and swiveled in the traveling direction of the traveling machine body 1, Unexpected lateral swing of the machine casing 4 due to the presence of the landing mechanism 5 can be suppressed.

  The present invention is not limited to the above-described embodiment, and the structure and the like of the pivoting mechanism 5 are designed with appropriate changes.

  As described above, the intended purpose can be sufficiently achieved.
