  The heaven processing unit 40 includes a rotatable heaven processing rotor 41. The celestial processing rotor 41 is supported via a celestial power transmission frame 42 so as to be swingable in the vertical direction with respect to the rotation center shaft 61a of the preprocessing rotor 61. The celestial processing rotor 41 is configured by radially attaching a plurality of tilling claws 44 to the rotation center shaft 41a.

  The celestial power transmission frame 42 is disposed between the celestial processing rotor 41 and the preprocessing rotor 61 and extends in a direction orthogonal to the rotation center axis 41 a of the celestial processing rotor 41.

It is supported by the support member 34. The support member 34 extends along the case above the preprocessing power transmission case 62. The heavenly power transmission frame 42 is supported via an urging device 35 provided between the support member 34 so that the vertical position can be adjusted. The mounting portion 10, the support member 34, and the connecting shaft 63 are collectively referred to as a machine body.

  As shown in FIG. 4, the urging device 35 includes a telescopic rod portion 36 and a compression spring 38 that is inserted into the rod portion 36 and urges the heaven processing rotor 41 to the old celestial heaven. Do it. The rod portion 36 includes a base end side rod 36a formed in a cylindrical shape, and a tip end side rod 36b that is inserted into the base end side rod 36a and can freely protrude.

  The proximal end side rod 36a is provided with a proximal end side hole portion into which the pin 39 can be inserted and removed, and the distal end side rod 36b is provided with a plurality of distal end side hole portions 36c arranged at predetermined intervals in the axial direction.

Moreover, the rod part 36 is provided in the state which faced diagonally below so that the front end side may be located below rather than the base end side. For this reason, the celestial processing rotor 41 and a grounding member 50 described later are urged by the compression spring 38 via the celestial power transmission frame 42, and the upwardly acting on the celestial processing rotor 41 and the grounding member 50. The impact force is absorbed by the compression deformation of the compression spring 38, and the impact force is relaxed.

  A celestial cover 47 covering the upper part of the rotor is disposed on the celestial process rotor 41. The support of the heaven cover 47 will be described later.

  Next, a grounding member 50 for grounding to the old fence's heaven field and making the amount of heaven cutting by the heaven field processing rotor 41 constant will be described with reference to FIGS. 4 and 5. FIG. As shown in FIG. 4, the ground member 50 is formed in a plate shape and is disposed so as to extend toward the heaven processing unit 40. The ground member 50 is formed with two inclined surfaces having different inclinations on the front side so that the rear side extends substantially horizontally and the front side is inclined upward as it advances forward. The front side of the grounding member 50 may be the grounding member 50 having a curved inclined surface.

  The grounding member 50 includes a connecting member 51 that is attached to the rear side and extends upward, and is connected to the parallel link mechanism 55. The connecting member 51 is formed in a rectangular tube shape, and a plurality of hole portions 51a arranged at predetermined intervals in the vertical direction are provided on the side surfaces thereof. The hole 51 a communicates with a hole provided in a connection holding member 52 (described later) that holds the connection member 51, and the pin 53 is inserted therethrough.

  The connection member 51 is held by a connection holding member 52 that is supported at the tip of the parallel link mechanism 55. The connection holding member 52 is formed in a rectangular tube shape, the connection member 51 is inserted therein, and a hole through which the pin 53 is inserted is provided on the side surface. For this reason, by inserting the pin 53 between the hole portions of the connection member 51 and the connection holding member 52, the protrusion length of the connection member 51 with respect to the connection holding member 52 is adjusted to the connection holding member 52. The connecting member 51 can be held. Therefore, by adjusting the protruding length of the connecting member 51 with respect to the connecting holding member 52, the vertical position of the grounding member 50 is adjusted, and the amount of cutting of the old fence by the heaven processing rotor 41 can be adjusted. it can. The connection holding member 52 is fixed to a distal end portion of an arm member 59 protruding from a movable member 58 disposed on the right side in the traveling direction of a parallel link mechanism 55 described later.

  The parallel link mechanism 55 is disposed on the rear side of the celestial power transmission frame 42 and includes a link member 56 extending along the celestial power transmission frame 42 and the celestial power transmission frame 42 (hereinafter referred to as a pair). A pair of link members 56 and 42), and a movable member 58 rotatably connected to the right side of the pair of link members 56 and 42 in the traveling direction. That is, the heaven power transmission frame 42 constitutes a part of the parallel link mechanism 55.

  One end of the link member 56 disposed on the upper side of the pair of link members 56 and 42 is pivotally connected to the lower portion of the bracket 34a provided on the support member 34 and extending downward, and the other end is The movable member 58 is rotatably connected to the upper end portion.

  The movable member 58 is disposed so as to extend in a substantially vertical direction, and a lower end portion of the movable member 58 is rotatably connected to a rear side surface of the heavenly power transmission frame 42, and an upper end portion is rotated to the end portion of the link member 56 described above. It is connected freely. As shown in FIG. 5, the rotation fulcrum Pa of the link member 56 with respect to the bracket, the rotation fulcrum Pb of the link member 56 with respect to the movable member 58, and the rotation fulcrum Pc of the movable member 58 with respect to the heavenly power transmission frame 42. And the rotation fulcrum Pd with respect to the connecting shaft 63 of the heavenly power transmission frame 42 is disposed so as to be positioned at each of the four corners of the parallelogram in a side view. That is, the distance between the rotation fulcrum Pa and the rotation fulcrum Pb is the same as the distance between the rotation fulcrum Pc and the rotation fulcrum Pd, and between the rotation fulcrum Pa and the rotation fulcrum Pd. And the distance between the rotation fulcrum Pb and the rotation fulcrum Pc is the same.

  For this reason, when the celestial power transmission frame 42 swings in the vertical direction around the rotation fulcrum Pd, the movable member 58 moves in the vertical direction while remaining in the vertical direction. Therefore, the grounding member 50 connected to the movable member 58 does not tilt even when the heavenly power transmission frame 42 swings in the vertical direction, and the contact surface with the kite is always maintained in the horizontal direction.

  Next, the heaven cover 47 that covers the heaven processing rotor 41 will be described with reference to FIG. As shown in FIG. 6, the celestial cover 47 is attached to the first connecting member 48 attached to the middle portion in the left-right direction with respect to the traveling direction of the upper part of the back surface, and to the right side of the traveling direction of the back surface of the celestial cover 47. The second link member 49 is supported by the parallel link mechanism 55.

  The first connecting member 48 is bent in a U shape in plan view, and the front side is connected to the back surface of the heaven cover 47 and the rear side is connected to the upper part of the movable member 58. The first connecting member 48 is arranged on the distal end side of the rod portion 36 so that the first connecting member 48 does not contact the rod portion 36 of the urging device 35 that swings in the vertical direction. The second connecting member 49 includes a plate member 49a attached to the back surface of the heaven cover 47, and a connecting arm member 49b having one end connected to the end of the plate member 49a and the other end connected to the arm member 59. It has. For this reason, the heaven cover 47 is stably supported by the parallel link mechanism 55 via the two members of the first connecting member 48 and the second connecting member 49. Therefore, like the grounding member 50, the heaven cover 47 does not tilt even if the heaven power transmission frame 42 swings in the vertical direction, and is always maintained in a constant posture.

  As shown in FIGS. 4 and 5, the grounding member 50 is connected to a movable member 58 that constitutes a part of the parallel link mechanism 55, and the movable member 58 is coaxial with the rotation center axis 41 a of the celestial processing rotor 41. Connected on top. For this reason, the grounding member 50 and the celestial processing rotor 41 move integrally with respect to the swinging of the celestial power transmission frame 42 in the vertical direction. Accordingly, the vertical distance Y between the bottom surface of the grounding member 50 and the lower end of the rotation trajectory of the tillage claw 44 of the top field processing rotor 41 is the same regardless of whether the top power transmission frame 42 swings in the vertical direction. Maintained constant.

  For this reason, as shown in FIG. 7A, FIG. 7B, and FIG. 7C, when the height of the heaven Ut of the old fence Uk is a predetermined height (see FIG. 7B). ), When the height of the old fence Uk heaven Ut is higher than the old fence Uk shown in FIG. 7B (see FIG. 7A), or the height of the heaven Ut of the old fence Uk. Even if it is lower than the old fence Uk shown in FIG. 7B (see FIG. 7C), the heaven field power transmission frame 42 is swung according to the height of the heaven field Ut of the old fence Uk. When the celestial processing rotor 41 is moved onto the celestial field Ut of the old fence Uk, the bottom surface of the grounding member 50 is always moved in a horizontal state, and the bottom surface of the grounding member 50 and the celestial processing rotor 41 are moved. The distance in the vertical direction from the lower end of the rotation trajectory of the tilling claw 44 is maintained at Y.

  As a comparison with the present invention, the movement of the grounding member 50 in the case where the parallel link mechanism 55 is not employed in the heaven cover 47 and the grounding member 50 but is simply connected to the end of the heavenly power transmission frame 42 is shown. This will be described with reference to FIG. 8 (a), 8 (b), and 8 (c) correspond to FIGS. 7 (a), 7 (b), and 7 (c), and FIG. 8 (b) The case where the height of the heaven field Ut of the old fence Uk is a predetermined height is shown, and FIG. 8 (a) shows that the height of the heaven field Ut of the old fence Uk is higher than that of the old fence Uk shown in FIG. 8 (b). FIG. 8C shows a case where the height of the heaven field Ut of the old fence Uk is lower than that of the old fence Uk shown in FIG. 8B.

  As shown in FIGS. 8 (a), 8 (b), and 8 (c), the heaven field power transmission frame 42 is swung in accordance with the height of the heaven field Ut of the old kite Uk, and the heaven field processing rotor. When 41 is moved onto the heaven field Ut of the old fence Uk, the bottom surface of the grounding member 50 is horizontal when the height of the heaven field Ut of the old fence Uk is a predetermined height. When the height is high and low, the bottom surface of the ground contact member 50 is inclined. Further, the vertical distance Y between the bottom surface of the grounding member 50 and the lower end of the rotation trajectory of the tillage claw 44 of the top field processing rotor 41 is such that the height of the old kite Uk is high when the height of the old kite Uk is high. Is larger than the predetermined height (Ya> Y), and when the height of the old ridge Uk is low, the height of the old ridge Uk is smaller than the predetermined height (Yc <Y ) In some cases, the bottom surface of the grounding member 50 is positioned below the heaven field Ut of the old fence Uk. In such a case, the heaven field cannot be cut. For this reason, when the parallel link mechanism 55 is not employed for the heaven field cover 47 and the grounding member 50 and is simply connected to the end of the heaven field power transmission frame 42, if the height of the old fence Uk changes, The cutting amount of the field Uk cannot be made constant.

  Next, the amount of heaven cut by the heaven field processing rotor 41 when the grounding member 50 is grounded to the old fence heaven field will be described with reference to FIGS. 9 (a) and 9 (b). First, the heaven field processing rotor 41 is grounded on the heaven field Ut of the old cage Uk, and the length of the rod portion 36 is adjusted so as to be in the middle of the movable range of the compression spring 38 of the urging device 35. Then, when the traveling machine body is caused to travel along the old fence Uk and the hammer coater 1 is driven, the heaven field processing rotor 41 rotates in the direction of arrow A as shown in FIG. The heaven Ut is cut away, and the shaved soil is released to the pretreatment rotor 61 side. On the other hand, the pretreatment rotor 61 rotates in the direction of the arrow B to cut the side surface Us of the old paddle Uk, and discharges the cut soil to the side of the old paddle Uk to perform filling. The trimming unit 70 (see FIG. 1) smears the piled up soil on the old sheared Uk.

  Here, in the case where the surface of the farm field H on which the traveling machine body travels is uneven, when the traveling machine body travels on the unevenness, the traveling machine body moves up and down, and the hull coater 1 also moves up and down. However, since the celestial processing rotor 41 and the grounding member 50 are always urged by the urging device 35 to the heaven Ut of the old kite Uk, for example, the traveling machine body travels on the convex portion and the coating machine 1 Is moved upward, the top side power transmission frame 42 swings downward about the rotation fulcrum Pd even if the entire coater 1 moves upward relative to the top field Ut of the old basket Uk. Then, the grounding member 50 is maintained in a state of being grounded to the heaven field Ut of the old fence Uk.

  At this time, since the vertical distance Y between the bottom surface of the grounding member 50 and the lower end of the rotation trajectory of the tillage claw 44 of the celestial processing rotor 41 is maintained constant (see FIG. 9A), As long as the member 50 is in contact with the heaven field Ut of the old fence Uk, the amount of cutting in the vertical direction of the heaven field Ut of the old fence Uk can be made constant Y by the heaven field processing rotor 41.

  On the other hand, when the traveling machine moves to the concave portion of the field and the spreader 1 moves downward, even if the entire spreader 1 moves downward, the heaven power transmission frame 42 has the rotation fulcrum Pd. The tip side swings upward as the center, and the grounding member 50 is maintained in a state where it is grounded to the heaven field Ut of the old kite Uk. For this reason, the cutting amount of the heaven field Ut of the old kite Uk by the heaven field processing rotor 41 can be maintained at a constant Y.

  Further, when the surface of the farm field H is not uneven and the height of the heaven field Ut of the old fence Uk changes or when the heaven field Ut is uneven, for example, a place where the grounding member 50 is low in the height of the heaven field Ut. When moving to the concave portion, the heavenly power transmission frame 42 swings downward on the rotation fulcrum Pd and keeps the grounding member 50 in contact with the inner surface of the concave portion (FIG. 7C). reference). Even in such a case, the cutting amount of the heaven field Ut of the old kite Uk by the heaven field processing rotor 41 can be maintained at a constant Y.

  On the other hand, when the grounding member 50 moves to a place where the heaven field Ut is high or to the convex part of the heaven field Ut, the heaven field power transmission frame 42 swings upward about the rotation fulcrum Pd, and the grounding member 50 is grounded. The member 50 is maintained in a state of being grounded on the convex portion (see FIG. 7A). Even in such a case, the cutting amount of the heaven field Ut of the old kite Uk by the heaven field processing rotor 41 can be maintained at a constant Y.

  As described above, the paddle coater 1 of the present application keeps the cutting amount of the top field Ut of the old paddle Uk by the top field processing rotor 41 regardless of the unevenness of the field H or the height change or unevenness of the old paddle Uk. can do. In this way, since the Xinjiang heaven field is formed on the heaven field cut to a certain depth, the Xinjiang heaven field is stably formed, and the formed Xinjiang heaven field is difficult to collapse. can do.

  In the above-described embodiment, the ground member 50 is provided on the right side in the traveling direction of the parallel link mechanism 55. However, the ground member 50 may be provided on the heaven cover 47. Even in this case, similarly to the case where the ground contact member 50 is provided on the right side in the traveling direction of the parallel link mechanism 55, the effect of making the amount of heaven cut by the heaven processing rotor 41 constant can be obtained.

  In the above-described embodiments, the grounding member 50 is a plate, but a cylindrical roller may be used. Also, as shown in FIGS. 10A and 10B, the grounding member 50 is located on the left side in the left-right direction with respect to the traveling direction of the heaven cover 47 in front of the traveling direction of the celestial processing rotor 41. Further, it may be disposed at the rear side in the traveling direction of the celestial processing rotor 41 and on the left side in the left-right direction with respect to the traveling direction of the celestial cover 47. As described above, the arrangement position of the grounding member 50 is not limited to the above-described embodiment, and may be in the vicinity of or close to the celestial processing rotor 41.
