1 to 6 show examples of embodiments of the present invention, and as shown in FIGS. 1 and 2, reference numeral 1 denotes a towed machine, which is towed by a towing mechanism (not shown), and as these towing mechanisms, for example, a field. Various structures such as a winch mechanism having a take-up drum arranged in the peripheral part of the field, a tractor having a winch mechanism arranged in the field scene M, and a winch mechanism arranged in the peripheral part of the field are used, and towed by these various towing mechanisms. A towing member R such as a rope or a towing wire is provided, and a connecting portion 1a to be detached and connected to a towing member R such as a towing rope or a towing wire of a towing mechanism (not shown) is provided at the front portion in the traveling direction of the towed machine 1. The towed machine body 1 is towed by a towing mechanism (not shown), and is formed so as to be able to travel on a field surface M, for example, a paddy field surface. A groove cutting body 2 capable of forming the above is arranged.

In this case, the grooves Setsutai 2 is formed by metal plate, FIGS. 1, 2, 3, as shown in FIG. 6, left and right to suit both inner slope W ₁ · _{W 1} of opposing culvert W 2a and 2a, upper edge plates 2b and 2b projecting from the upper edges of each of the inclined plates 2a and 2a, and a bottom plate 2c facing the bottom surface. The side view is formed in a substantially tapered triangular shape, and the groove cutting body 2 is attached by the rear transfer plate 1b of the towed machine body 1, the front vertical plate 1c and the cross plate 1d, and is attached to the cross plate 1d in pairs on the left and right. The holding plates 1e and 1e of the above are projected, and a connecting portion 1a that is detachably connected to a traction member R such as a traction rope or a traction wire of the traction mechanism (not shown) is provided between the front portions of the pair of left and right holding plates 1e and 1e. The axle 3a is attached to the rear portion of the towed machine 1 so as to be orthogonal to the traveling direction, and the stable wheel bodies 3 and 3 are orthogonal to the traveling direction at both left and right ends of the axle 3a by the position adjusting mechanism 4. The stable wheel bodies 3 and 3 are provided so as to be adjustable in position in the direction, and the stable wheel bodies 3 and 3 are composed of a hub portion 3b, a spoke portion 3c and a wheel portion 3d. In this case, a plurality of stable wheel bodies 3 and 3 are provided as the position adjusting mechanism 4 in the axial direction of the axle 3a. Selection holes 3e ・ 3e ・ ・ are formed, the hub part 3b of the stable wheel body 3 and 3 is inserted into the axle 3a, the hub part 3b is arranged between the selected selection holes 3e and 3e, and the selection holes 3e ・ ・A stop pin 3f is inserted through the 3e to adjust the arrangement position of the stable wheel bodies 3 and 3 to the left and right.

Reference numeral 5 denotes a weight body, and as shown in FIGS. 4, 5, and 6, an installation portion 6 capable of hooking the hooking portion 5a of the weight body 5 is formed at the rear portion of the towed machine body 1, and the weight body is formed. By installing 5 and adjusting the weight of the heavy cone 5, the penetration position of the groove cut body 2 with respect to the field soil is adjusted via the towed machine body 1, and the above drainage is adjusted by adjusting the penetration position of the groove cut body 2 with respect to the field soil. It is configured to adjust the groove depth H of the groove W.

Since the example of this embodiment has the above configuration, as shown in FIG. 5, a tow member R such as a tow rope or a tow wire of various tow mechanisms (not shown) is connected to a connecting portion 1a of the towed machine body 1 to be towed. The machine body 1 is towed by a towing mechanism (not shown), and the towed machine body 1 is towed and advanced in the field scene M, and as the towed machine body 1 is towed, the groove cutting body 2 drains the machine body 2 into the field scene M. A groove W can be formed, and by pulling the towed machine body 1 by a towing mechanism, a drainage groove W can be formed in the field scene M by the groove cutting body 2, and the operator can form a groove cutting body in the field. It is not necessary to accompany the towed machine 1 provided with 2, and the labor of the operator can be reduced and the grooving workability can be improved, and the left and right sides of the towed machine 1 can be improved. Since the stable wheel bodies 3 and 3 are arranged on both side portions, the towed machine body 1 can be towed in the field scene M in a stable state, and the grooving work can be smoothly performed by the grooving body 2. This can be done and the grooving workability can be improved.

In this case, since the towed machine 1 is provided with the position adjusting mechanism 4 for adjusting the arrangement position of the stable wheel bodies 3 and 3, the stable wheel is provided according to the rice stock K and impurities existing in the field scene M. The arrangement position of the bodies 3 and 3 can be adjusted, the stable wheel body 3 and 3 can be smoothly towed, and the grooving body 2 can smoothly perform the grooving work. Further, in this case, since the installation portion 6 of the weight body 5 for adjusting the groove depth H of the drainage groove W is arranged in the towed machine body 1, the weights of different weights are different. The degree of immersion of the groove cutting body 2 with respect to the field scene M can be adjusted by adjusting the number of the weight bodies 5 and the weight bodies 5, and the groove depth H of the drainage groove W can be adjusted by adjusting the degree of immersion of the groove cutting body 2. Can be adjusted, and the drainage groove W having an arbitrary groove depth H can be grooved.

The present invention is not limited to the above embodiment, and for example, the structure of the towed machine body 1, the groove cutting body 2, the stable wheel body 3, the position adjusting mechanism 4, the weight body 5, and the installation portion 6 The form and the like are appropriately changed and designed.

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