Can be marked.

  Further, as is clear from FIGS. 3 and 6 and the like, one pin hole 61 and two bolt holes 62 are formed on the upper surfaces of the left and right ends of the outer pipe 56. Note that, on each lower surface of the left and right end portions of the outer pipe 56, one pin hole portion 63 is formed so as to face the upper surface side pin hole portion 61.

  Then, the bolt 67 inserted into the bolt hole 62 is screwed to the nut 66 welded and fixed to the upper end portion of the plate-shaped stopper member 65, so that the stopper member 65 is fixed to the outer pipe. Arranged and fixed in the end of 56. The stopper member 65 has an inverted U-shape, and the stopper member 65 has an opening 65a that opens downward.

  Next, the configuration of the left marker body 52 will be described. The left marker body 52 is slidable in the left-right direction along the rotating body 51 with respect to the rotating body 51 and is at a predetermined angle (for example, at least 90). Degree) a movable member 71 that is horizontally movable in the left-right direction, a marker member 72 that is provided in the movable member 71 so as to be pivotable in the front-rear direction, and that marks a field (for example, a groove), and the marker member And a coil spring 73 that is an urging member for rotating the 72 forward.

  As shown in FIGS. 3, 6, 7, and the like, the moving member 71 has an inner pipe 76 that is an elongated cylindrical portion that is elongated in the left-right direction, and this inner pipe 76 is the outer pipe of the rotating body 51. Access to the pipe 56 is possible.

  An engagement member 77 that prevents the inner pipe 76 from coming out of the outer pipe 56 due to the engagement with the stop member 65 of the rotating body 51 is fixed to the inner end portion of the inner pipe 76 by welding or the like. The engaging member 77 includes a plate-shaped annular portion 78, a U-shaped portion 79 having a U-shaped cross section formed by a bent plate fixed to the lower portion of the annular portion 78, and the U-shaped portion.

The U-shaped portion 79 abuts and engages with the stopper member 65 to prevent the inner pipe 76 from coming out of the outer pipe 56. Further, the convex portion 80 enters the opening 65a of the stop member 65 and restricts the inner pipe 76 from rotating with respect to the outer pipe 56. As a result, the use position pin on the inner end side of the inner pipe 76 The hole 81 is opposed to the upper and lower pin holes 61, 63. And if the positioning pin 70 which is a positioning means is inserted in these opposing hole parts 61, 63, 81, the left marker body 52 will be positioned in the use position.

  In addition, a stopper plate 83, which is an abutting member having an L-shaped cross section made of a bent plate, is fixed in the vicinity of the outer end portion of the inner pipe 76 by welding or the like. The stopper plate 83 has a contact portion 84 that contacts the outer end surface of the lower surface portion of the outer pipe 56. When the contact portion 84 of the stopper plate 83 contacts the outer end surface of the lower surface portion of the outer pipe 56, the non-use position pin hole portion 82 on the outer end side of the inner pipe 76 becomes the upper and lower pin hole portions 61, Opposite to 63. When the positioning pin 70 is inserted into the opposed holes 61, 63, 82, the left marker body 52 is positioned in a state where it is located at the non-use position. The non-use position pin hole 82 on the outer end side is shifted by 90 ° with respect to the use position pin hole 81 on the inner end side.

  Further, in the vicinity of the outer end portion of the inner pipe 76, a protruding plate 85 made of a flat plate is fixed by welding or the like so as to protrude toward the side opposite to the stopper plate 83 side. A plurality of, for example, three spring pressure adjusting holes 86 are formed in the protruding plate 85. One end of a coil spring 73 is attached to one spring pressure adjusting hole 86 selected from the three spring pressure adjusting holes 86. The other end of the coil spring 73 is attached to the spring hole 89 of the pin attachment plate 88.

  As shown in FIGS. 7 and 8, the marker member 72 includes a turning portion 91 that is rotatably attached to the outer peripheral side of the outer end portion of the inner pipe 76 of the moving member 71, and the turning portion 91. The arm portion 94 is mounted on the arm mounting collar 92 with a retaining bolt 93 so that the vertical position can be adjusted, and the substantially disc-shaped groove is rotatably mounted on the lower end portion of the arm portion 94 via the shaft portion 96. And a marker portion 95 for attachment.

  The rotating portion 91 is, for example, a cylindrical rotating collar 97 that is rotatably fitted to the outer peripheral side of the outer end portion of the inner pipe 76, and is fixed to the outer peripheral surface of the rotating collar 97 by welding or the like. A cylindrical arm mounting collar 92 and a pin mounting plate 88 fixed to the rotating collar 97 by welding or the like are used. The rotating collar 97 is attached to the outer end portion of the inner pipe 76 by a mounting bolt 98 and a washer 99. The arm mounting collar 92 is formed with a screw hole portion 100 into which a set bolt 93 can be screwed.

  A plurality of, for example, three pin mounting holes 101 are formed in the pin mounting plate 88. A contact pin 102 is detachably attached to a pin attachment hole 101 selected from these three pin attachment holes 101 by a pin fixing member (for example, an R pin) 103. Yes.

  The contact pin 102 is in contact with the protruding plate 85 of the moving member 71 based on the biasing force of the coil spring 73 in a normal state. However, when an external force of a predetermined magnitude or more is applied to the marker unit 95 due to, for example, a collision with a clot or stone, the marker member 72 rotates backward with respect to the moving member 71 against the biasing force of the coil spring 73. As a result, the contact pin 102 moves away from the protruding plate 85 of the moving member 71. For this reason, it is possible to prevent the marker member 72 from being damaged by an external force from the field side. When the external force no longer acts, the marker member 72 rotates forward with respect to the moving member 71 by the biasing force of the coil spring 73 and returns to the original state (see FIG. 8).

  Next, the operation and the like of the farm work machine 1 will be described.

  When the agricultural work machine 1 is connected to the rear part of the tractor T and moved forward in the traveling direction by the forward traveling of the tractor T, the coulter 32 of the groove forming means 5 forms a sowing groove on the surface part (uncultivated soil) of the field, Thereafter, the sowing means 6 sows seeds and fertilizers in the sowing grooves, and behind them, the pressure ring 46 suppresses the covering soil covering the seeds and fertilizers in a cross-sectional mountain shape.

  Thus, the sowing fertilization work is performed. At this time, as shown in FIG. 9, the tractor T travels in the field along the marks (for example, grooves) attached to the field by the marker bodies 52 and 53.

  Specifically, first, the left and right marker bodies 52 and 53 respectively positioned at the use positions are used to mark the field. At this time, the operator inserts the fixing pin 60 into the left and right use holes 23 of the protruding frame 21 to set the rotating body 51 in a horizontal state.

  Next, after reaching the end of the field (the end opposite to the entrance / exit side) and turning the tractor T, this time, using only the right side marker body 53 located at the use position, a mark is placed on the field. wear.

  At this time, the operator rotates the rotating body 51 in the horizontal state with respect to the support portion 20 of the work machine body 2 by a predetermined angle (for example, 3 °) about the rotation center axis X, and then the fixing pin 60. Is inserted into the right use hole 22 of the projecting frame 21, and the rotating body 51 is set in a downwardly inclined state. Note that the left marker body 52 remains in the use position, but is not grounded and has no mark.

  Next, after reaching the end of the field (end on the entrance / exit side) and turning the tractor T, this time, only the left marker body 52 located at the use position is used to mark the field.

When the work is finished, both the left marker body 52 and the right marker body 53 are stored in the non-use position so as not to disturb.

  And according to such a farming machine 1, when using only the left marker body 52, the rotating body 51 is set in a downwardly inclined state, and when using only the right marker body 53, the rotating body 51 is set. Therefore, it is easy to switch the left and right markers at the end of the field compared to the conventional configuration, and work efficiency can be improved.

  In addition, since the tilt angle α with respect to the horizontal direction of the rotating body 51 in the inclined state is an angle in the range of 2 ° to 7 °, the rotating angle of the rotating body 51 is small, and the work efficiency can be appropriately improved. In addition, the rotating body 51 can be easily arranged in a narrow place.

  Further, each of the left marker body 52 and the right marker body 53 is provided on the central rotating body 51 so that the position of the left marker body 52 and the right marker body 53 can be changed between the use position and the non-use position. It can be stored in a non-use position.

  In the above embodiment, the manual type in which the rotating body 51 is manually rotated around the rotation center axis (shaft portion 57) X with respect to the support portion 20 of the work machine body 2 has been described. As shown in FIG. 10, the rotating body 51 is moved in the vertical direction about the rotation center axis X with respect to the support portion 20 of the work machine body 2 so that the work efficiency can be improved more easily than the manual type. It may be configured to include a motor (electric motor, hydraulic motor, etc.) 110 that is a driving means for rotating the motor.

  As shown in FIG. 10, the motor 110 includes a motor body 111 attached to the projecting frame (driving means attachment portion) 21 of the work machine body 2, and a motor side fixed to the output shaft 112 of the motor body 111. And a gear 113. The motor side gear 113 meshes with a fan-like rotating body side gear 114 fixed to the front surface of the rotating body 51 near the outer end portion of the outer pipe 56.

  For example, when an operator on the tractor T presses the left and right use buttons of the remote control means (not shown), the rotating body 51 is set and fixed in a horizontal state. In this state, the left marker body 52 and the right marker body 53 are fixed. Both can be grounded to the field to mark the field. Further, when the operator presses the left use button of the remote control means, the rotating body 51 is set and fixed to the lower left inclined state (inclination angle α). In this state, only the left marker body 52 is grounded to the field. It is possible to mark the field. Further, when the operator presses the right use button on the remote control means, the rotating body 51 is set and fixed to the right-down inclination state (inclination angle α). In this state, only the right marker body 53 is grounded to the field. It is possible to mark the field.

  The driving means is not limited to the motor 110, and may be, for example, an extendable cylinder.

  Further, for example, in the manual type shown in FIG. 1, when an operator who rides on the tractor T operates an operation member (a wire, a string, or the like), the rotating body 51 rotates up and down with respect to the support portion 20. It is also possible.

  Furthermore, in any embodiment, the type of farm work by the work machine body 2 is not limited to the sowing work or the like and is arbitrary.

  Further, for example, a configuration in which the marker bodies 52 and 53 are detachably provided on both sides of the rotating body 51 may be used. Furthermore, the marker part 95 of the marker bodies 52 and 53 may be constituted by, for example, a chain or the like.
