It is configured as possible.

Reference numeral 9 denotes a water channel opening mechanism, which is formed at the rear position in the advancing direction D of the grooved body 2, that is, in the grooved body 2 at the front position, at the left position in FIGS. The groove cut body 2 is formed at the right position in the figure, and is as shown in FIGS. 1, 2, 3, 4, 5, 6, 7, 8, and 9. parts and top _{T 1} and the lower surface _{T 1} of the respective grooves Setsutai 2.2 of the right and left slopes member 2a, 2a each triangular rear position consists of a rectangular three sides _{T 2,} T 2, _{T 2} collapse while pivoted to one of the corner edges extending obliquely vertically of the corner edge of the crossing angle of the side surface T ₂ and the side surface T ₂ of the triangular tubular member shaped collapse member 9a by the pivot portion 9b three interior slope of the side surface 9c of the outer position culvert W of the rectangular side _{T 2 · T 2 · T 2} W of the pressing to collapse member 9a toward the member 9a outward ₁ The pressing spring member 9d to repression contact with W ₁ are configured by providing.

Thus, as shown in FIG. 10, at the time of groove switching progression, the three sides 9c of the outer positions of the rectangular side T _{2 ·} T ₂ · T ₂ is pushed spring member 9d collapse member 9a When it comes into contact with the inner slopes W ₁ and W ₁ of the drainage groove W and reaches the drainage groove W that has been cut as shown in FIGS. 10 to 11, the inner slope of the drainage groove W disintegrating member 9a that repression contact with W ₁ is押開swung outwardly by pushing the spring member 9d as a fulcrum pivot portion 9b is released from the inner slope W ₁ of the culvert W, the disintegrating member 9a As shown in FIG. 1 and FIG. 2, the side soil discharges W ₂ and W ₂ caused by the progress of the groove cutting closing the water channel of the intersecting drain grooves W are collapsed as shown in FIGS. the side surface 9c of the outer position of the member 9a Hyde W ₂ · _{W 2} to level the field surface M by pushing outward Broken, thereby would prevent the waterway blockage of the drainage groove W intersecting grooves cut already by dumping W ₂ · _{W 2} on both sides the position of the drainage grooves W due to the grooves cut progresses.

  Since the first embodiment of the present invention has the above-described configuration, as shown in FIG. 12, the advancing mechanism 4 including the drive source 3 can be remotely controlled by the radio control means 8, and the body 1 is advanced by the remote control to move the groove. It is possible to cut the drainage groove W between the plurality of strips or the stock of the farm scene M with the cut body 2, reduce the labor of the operator, and improve the grooving workability.

  In this case, it is possible to rotate the helical propulsion shaft 5 having the helical scraper blade 5a on the outer peripheral portion by remote control, and the rotational axis L of the helical propulsion shaft 5 is provided in the traveling direction D of the airframe 1. The machine body 1 can be advanced in the farm scene M by the rotation of the spiral propulsion shaft 5, and the machine body 1 can be reciprocated in the farm scene M by the forward / reverse rotation of the spiral propulsion shaft 5. The body 1 is advanced by maneuvering, and the drainage groove W can be grooved between a plurality of strips or stocks of the farm scene M by the grooving body 2, which can reduce the labor of the operator, and the grooving work. Can be improved.

  In this case, since the grooved bodies 2 and 2 are provided at both the front position and the rear position of the airframe 1, the airframe 1 can be moved forward by the forward rotation of the helical propulsion shaft 5, and the spiral propulsion is performed. The body 1 can be moved backward by the reverse rotation of the shaft 5. For example, an operator on the kite F can advance the aircraft 1 forward by remote control between the striations or between the stocks toward the facing kite F. The drainage groove W can be grooved by the grooving body 2 at the position, and immediately before the airframe 1 reaches the opposite side F, the airframe 1 is moved backward by remote control, and the groove at the rear position is moved forward during the backward movement. The drainage groove W that has been grooved by the cut body 2 when it advances forward can be grooved or repaired again, and immediately before the machine body 1 reaches the heel F on the near side, the backward movement of the machine body 1 is stopped, and the machine body Lift 1 and fuselage 1 The installation is made between the adjacent strips or between the stocks, and, as described above, the worker on the kite F advances the machine body 1 forward by remote control between the strips or the stock toward the facing kite F. 2, the drainage groove W can be grooved, and immediately before the aircraft 1 reaches the opposing kite F, after the aircraft 1 is stopped by remote control, the vehicle 1 is moved backward and immediately before the aircraft 1 reaches the kite F. , The backward movement of the machine body 1 is stopped, and by repeating the reciprocating movement of the machine body 1, the drainage groove W can be grooved by a single worker between a plurality of strips or stocks in the field scene M. Labor can be reduced, and grooving workability can be improved.

  Also, for example, as another embodiment, by providing the grooved body 2 at one of the front position and the rear position of the airframe 1, work is performed on the front side F and on the opposite side F respectively. Two workers can divide the drainage groove W in the field M by lifting and moving to the next streak or stock with advance and reversal by remote control of the airframe 1 by two operators. The labor of a worker can be reduced, and the grooving workability can be improved.

Also, in this case, since the meandering preventing member 2d for preventing the meandering of the airframe 1 is provided in the grooved bodies 2 and 2, the straightness of the forward and backward reciprocation of the airframe 1 can be improved, and the drainage function can be improved. A good drainage groove W can be cut, and in this case, the machine body 1 intersects the machined body with the drainage W ₂ and W _{2 on} both sides of the drainage groove W as the groove cutting progresses. waterway blockage of the drainage groove W because there is provided a water passage opening mechanism 9 for preventing collapse the dumping W ₂ · _{W 2,} it is possible to prevent the water channel blockage of the drainage groove W intersecting grooves cut already, cross It is possible to maintain the mutual water channel of the drainage grooves W and W, and to cut the drainage groove W having a good drainage function.

  The second embodiment shown in FIGS. 13 and 14 shows another structure. In this case, blade portions 5c, 5c,... Capable of removing weeds in the farm scene M are arranged on the outer peripheral edge of the spiral propulsion shaft 5. doing.

  In the second embodiment, the same effects as the first embodiment can be obtained, and the weeds in the field M are removed by the blade portions 5c, 5c,. The weeding operation can be performed simultaneously with the grooving of the drainage groove W.

The present invention is not limited to the above-described embodiment. For example, in the first embodiment, the grooved bodies 2 and 2 are arranged at the front and rear positions and the rear position of the machine body 1. When the structure in which the grooved body 2 is provided at one of the front position and the rear position of the body 1 shown as the other embodiment is employed, the front of the body 1 in which the grooved body 2 is not provided. the part position or rear position also possible to use a construction in which to place the structure or member, such as during retraction progress is not inhibited by the inner slope W ₁ ditch W were grooved by forward progress, also body 1, a groove The structure and form of the cut body 2, the meandering prevention member 2 d, the drive source 3, the advance mechanism 4, the spiral propulsion shaft 5, the rotation drive mechanism 7, the radio control means 8, and the water channel opening mechanism 9 are designed with appropriate changes.

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