[0015]
Next, the operation switch of the present invention will be described.
The operation switches 60 are switches for releasing the drawing markers 40, 40 or pulling them up for storage or the like. As shown in FIG. 4, the operation switches 60 are connected to a controller 72. The controller 72 includes motors 71, 71 for releasing and pulling up the markers 40, 40 via relays 73, 73. Connected. The motors 71, 71 are connected to the markers 40, 40 via wires 74, 74. By operating the motors 71, 71 by operating the operation switches 60, 60, the markers 40, 40 are released.・ It is configured to pull up. It should be noted that it is also possible to adopt a configuration in which the wires 71 are directly provided without providing the wires 74 between the motors 71 and the markers 40. Further, the storage of the markers 40 may be performed in conjunction with the elevation of the planting portion, as in the related art, and may be operated by the operation switches 60 when releasing and lowering. As described above, by using the controller 72, the marker 40 is released or pulled up by pressing the operation switch 60 once, that is, the operation of releasing or pulling up the marker 40 is completed. Until then, there is no need to keep pressing the operation switches 60, and the operability is improved.
[0016]
Next, the arrangement of the operation switches will be described.
The operation switches 60 are arranged in the handle wheel 14b of the steering handle 14. Here, as shown in FIG. 5, the steering handle 14 has spokes 14a projecting from the upper end of the handle shaft 28 in the radial direction (radial direction), and the steering wheel 14b is fixed to the tips of the spokes 14a. The inside of the handle wheel 14b means that it is located inside the handle wheel 14b (center side) in plan view.
The operation switches 60 are arranged at positions where the operator can operate the operation switches 60 and 60 with fingers (for example, thumbs) while holding the steering handle 14.
In the present embodiment, as shown in FIG. 5, the steering wheel 14 is formed with a substantially circular handle wheel 14b, and the spokes 14a, 14a extend diagonally left and right from the center of the handle wheel 14b. Is formed.
The operation switches 60 are disposed on the left and right spokes 14a in the handle wheel 14b or in front of the spokes 14a 14a, and the mounting portion 17 disposed in front of the spokes 14a 14a.・ Mounted on 17. Further, the mounting portions 17 may be arranged behind the spokes 14a.
The mounting portions 17 are disposed at positions surrounded by the left and right spokes 14a and 14a and the handle wheel 14b, and forward from the front surfaces of the left and right spokes 14a and 14a. It is formed to protrude inward from the side surface.
[0017]
The operation switches 60 are mounted on the upper surfaces of the mounting portions 17, and the upper surfaces of the operation switches 60 are disposed lower than the upper surface of the handle wheel 14 b.
As shown in FIG. 6, the mounting portion 17 is formed so as to protrude from a lower portion of the handle wheel 14b, and has a thickness of about half or less of the diameter of the handle wheel 14b.
The operation switch 60 is mounted on the upper surface of the mounting portion 17, and the upper surface of the operation switch 60 is configured to be lower than the upper surface of the handle wheel 14b.
By arranging the operation switches 60 and 60 at a position lower than the upper surface of the handle wheel 14b of the steering handle 14 as described above, the operation switches 60 and 60 are erroneously operated, that is, the operation switches 60 are erroneously operated when the steering handle 14 is operated. It is possible to prevent unintended operations such as touching 60.
[0018]
As shown in FIG. 6, the operation switches 60 are constituted by seesaw switches.
The operation switch 60 is a neutral return type switch that returns to an original position (neutral position) when the hand is released from the operation section of the switch. The marker 40 is released by pressing one side of the operation switch 60. , By pressing the other side, the marker 40 is pulled up.
The operation switch is not limited to a seesaw switch, and a toggle switch, a push button switch, or the like can be used.
[0019]
The operation switches 60 and 60 are disposed on both left and right sides of the steering handle 14. The operation switches 60 and 60 are provided on the right side of the steering handle 14 at a position where the vehicle is going straight. The operation switch 60 for operating the operation of the marker 40 is arranged on the left side, and the operation switch 60 for operating the left marker 40 is arranged on the left side.
Since the release and pull-up operations of the markers 40 and 40 are normally performed when the vehicle is in a straight-ahead state, the operation switches 60 and 60 are located on both left and right sides while the steering handle 14 is in a straight-ahead state. The left and right positions of the operation switches 60 are the same so that an error is unlikely to occur when releasing or pulling up. Therefore, since the position of the operation switch 60 matches the direction of the selected marker 40, the operation of the marker 40 becomes easy.
[0020]
As described above, the operation switches 60, 60 for releasing and raising the markers 40, 40 are provided in the handle wheel 14b of the steering handle 14, so that the operation can be performed with the hand on the steering handle 14. Thus, the operability of the markers 40 is significantly improved, and as a result, the work efficiency can be greatly improved.
[0021]
Also, the operation switches 60 can be mounted on the left and right spokes 14a of the steering handle 14.
As shown in FIG. 7, the operation switches 60 are disposed on the upper surfaces of the spokes 14a. The operation switches 60 are arranged at positions where the operator can operate the operation switches 60 and 60 with fingers (for example, thumbs) while holding the steering handle 14.
The operation switches 60 are disposed for each of the left and right spokes 14a. When the vehicle is in a straight-ahead state, the operation switches 60 disposed on the left side of the steering handle 14 are used to operate the left and right spokes 14a. The marker is operated, and the operation of the right marker is performed by the operation switch 60 arranged on the right side of the steering handle 14. With this configuration, the position of the operation switch 60 matches the direction of the selected marker 40, as described above, so that the marker 40 can be easily operated.
[0022]
As shown in FIG. 8, a recess 14c is formed at the position where the operation switch 60 is attached to the spoke 14a, and the operation switch 60 enters the recess 14c.
The recess 14c is formed such that the upper surface of the operation switch 60 does not protrude from the upper surface of the spoke 14a when the operation switch 60 is disposed inside.
Thus, by arranging the operation switches 60 on the spokes 14a of the steering handle 14, the operation can be performed while the hand is being attached to the steering handle 14, and the operability of the markers 40 is significantly improved. As a result, the working efficiency can be greatly improved.
Further, by disposing the operation switches 60, 60 at a position lower than the upper surfaces of the spokes 14a, 14a of the steering handle 14, erroneous operation of the operation switches 60, 60, that is, the operation switch 60 -It is possible to prevent an unintended operation such as touching 60.
[0023]
