The upward impact force acting on 60 is reduced.

  A celestial cover 38 that covers the upper portion of the rotor is disposed on the celestial processing rotor 32. The heaven cover 38 is attached to the heaven power transmission frame 33.

  Next, a grounding member 60 for grounding to the old fence's heaven field and breaking the heaven field at a certain depth by the heaven field processing rotor 32 will be described with reference to FIGS. As shown in FIGS. 2 and 3, the grounding member 60 is attached to the front end portion of the rotation center shaft 32 a of the celestial processing rotor 32.

  The grounding member 60 is formed of a plate-like metal material, and includes an arm part 60a that is attached to the rotation center shaft 32a and extends downward, and a grounding main body part 60b that is connected to the lower part of the arm part 60a and extends forward. It becomes. The arm portion 60a is attached to the rotation center shaft 32a so as to always extend downward regardless of the rotation of the rotation center shaft 32a.

  As shown in FIG. 4A, the grounding main body 60b is formed in a plate shape and extends forward in the traveling direction. The rear side of the grounding member 60b extends substantially horizontally, and the front side of the grounding main body 60b is formed to tilt upward as it advances forward. The front side of the grounding main body 60b may have a curved shape. The grounding member 60 is not limited to a plate shape, and may be formed of a rotating body such as a cylinder, a sphere, or a wheel.

  4B is further described, the ground contact member 60 is in front of the traveling direction of the heaven field processing rotor 32 in the excavation range H where the heaven field rotor 32 cuts off the heaven field Kt of the old fence K. It arrange | positions below the rotation center axis | shaft 32a of the heaven field processing rotor 32 (just below in drawing). Further, the lower surface of the grounding main body 60b is disposed at a position having a predetermined distance Y inside the rotation locus L of the tip of the tilling claw 32b of the heaven processing rotor 32. For this reason, when the grounding main body 60b contacts the heaven field Kt of the old fence K, the heaven field processing rotor 32 can cut the heaven field Kt at a certain depth corresponding to the predetermined distance Y.

  Here, as a comparison with the present invention, refer to FIGS. 5A to 5D for the breaking of the heaven field Kt when the grounding member 60 is disposed outside the excavation range H of the heaven field processing rotor 32. FIG. While explaining.

  5A shows the case where the heaven field Kt extends in a substantially horizontal direction, FIG. 5B shows the case where the heaven field Kt is inclined, and FIG. 5C shows the heaven field Kt being recessed. FIG. 5D shows a case where the heaven field Kt is formed in a step shape.

  As shown in FIG. 5A, when the heaven field Kt extends in a substantially horizontal direction, the tilling claw 32b of the heaven field processing rotor 32 is positioned below the lower surface of the grounding main body 60b of the grounding member 60. Since the rotation trajectory L at the tip of the traverse passes, the heaven field Kt can be cut at a certain depth.

  In addition, as shown in FIG. 5C, when the center part in the width direction of the heaven field Kt is formed in a concave shape that is depressed downward, the grounding main body part 60b touches the concave bottom part of the heaven field Kt. Since the portion of the heaven field Kt facing the field processing rotor 32 is in a state where the soil is raised, the amount of the heaven field Kt cut by the heaven field processing rotor 32 increases.

  Further, as shown in FIG. 5D, when the ground field Kt is formed in a step shape such that one side in the width direction is higher in height than the other side, the grounding member 60 has a high step shape. If the part of the heaven Kt that is in contact with the part and faces the celestial processing rotor 32 is a part having a low height, the celestial processing rotor 32 is lifted from the celestial Kt and cuts off the celestial Kt. I can't.

  As described above, when the grounding member 60 is disposed outside the excavation range H of the celestial processing rotor 32, the celestial processing rotor 32 cannot cut the celestial field at a certain depth when the state of the celestial field Kt changes. .

  On the other hand, as shown in FIGS. 4A and 4B, the grounding member 60 according to the present invention is within the excavation range H of the celestial processing rotor 32 and the celestial processing rotor 32 advances. Since it is arranged forward in the direction and further below the rotation center shaft 32a of the celestial processing rotor 32, when the grounding member 60 is grounded to the celestial field Kt regardless of the state of the celestial field Kt, the grounding member 60 is provided. The celestial field Kt grounded by the grounding member 60 is cut off by the celestial field processing rotor 32 arranged on the rear side in the traveling direction. For this reason, the celestial field Kt can be cut at a certain depth regardless of the state of the celestial field Kt.

  The position of the grounding member 60 is not limited to the position just below the rotation center shaft 32a of the heaven processing rotor 32, but is within the excavation range H of the heaven processing rotor 32 and in front of the heaven processing rotor 32. The position may be shifted laterally with respect to the center of the rotation center shaft 32a.

  The ground member 60 is shown attached to the front end of the rotation center shaft 32a. However, the grounding member 60 is attached to the front side of the heaven cover 38 that covers the heaven processing rotor 32, or the heaven field that supports the heaven cover 38. You may attach via the power transmission flame | frame 33. FIG.
