For this reason, between the front end of the side plate portion 84 ′ between the pair of insertion holes 84a where no packing 87 is interposed and the mounting plate 71, as shown in FIG. A through-hole 88 that communicates with each other is formed. The through hole 88 allows the moisture in the housing recess 82a to be discharged to the outside. The packing 87 is made of elastically deformable rubber, cork rubber, or the like. The control box 82 is integrally formed of resin, synthetic resin (ABS resin, FRP) or the like, and can transmit a command signal transmitted from the wireless command device 60.

  The electronic board 100 accommodated in the control box 82 includes an antenna 101 that receives a command signal from the wireless command device 60, and an electric hydraulic cylinder 57 (see FIG. 2) according to the command signal received by the antenna 101. A control unit 102 that controls the operation of an actuator such as a drive motor is provided. The antenna 101 is formed on the surface side of the electronic substrate 100, and the length of the antenna 101 is set by the wavelength of the electromagnetic wave transmitted from the wireless command device 60.

  Referring to FIG. 1 (b), the electronic board 100 is further described with reference to a board-side electric wire 103 electrically connected to the control unit 102. A board-side connector 104 is connected to the tip of the board-side electric wire 103. Is attached. The board-side electric wire 103 extends to the outside of the control box through a through hole 84 a provided in the control box 82, the tip side thereof goes around the lower end outside the mounting plate 71, and the board-side connector 104 is connected to the back surface of the mounting plate 71. It is arranged around the lower end of the side. The board-side connector 104 is connected to a drive-side connector 106 attached to the distal end portion of the drive-side electric wire 105 connected to the actuator.

  The control box 82 attached to the attachment plate 71 is covered with a cover 110 as shown in FIGS. 1 (a) and 1 (b). The cover 110 is configured to cover the top plate portion 83 and the side plate portion 84 of the control box 82 and is detachably attached to the attachment plate 71. The cover 110 has an upper wall portion 111 that covers the top plate portion 83 and side wall portions 112 a and 112 b that extend downward from the outer periphery of the upper wall portion 111.

  The upper wall portion 111 is formed in a planar shape, and extends substantially parallel to the top plate portion 83 in a state where the cover 110 is attached to the attachment plate 71. The side wall 112 a that covers the upper side of the control box 82 among the side walls 112 is locked to the peripheral edge of the mounting plate 71 to which the upper side of the control box 82 is attached. A step 113 is formed at the tip of the side wall 112 a, and the step 113 locks the tip of the side wall 112 a to the peripheral edge of the mounting plate 71.

  Side wall part 112b which covers the lower side of control box 82 among side wall parts 112 has stepped part 114 latched to the peripheral part of mounting plate 71 which attached the lower side of control box 82, and the tip of side wall part 112b The portion extends further downward beyond the mounting plate 71 and surrounds the board side connector 104 and the drive side connector 106. Similar to the control box 82, the cover 110 is integrally formed of resin, synthetic resin (ABS resin, FRP) or the like, and can transmit a command signal transmitted from the wireless command device 60.

  As described above, the electronic substrate 100 accommodated in the wireless reception control device 70 is placed on the side of the worker who has boarded the traveling machine body 90 in the working state of the tilling work machine 1 as shown in FIGS. Since the posture is maintained, when the worker M who has boarded the driver's seat 91 of the traveling machine body 90 faces the agricultural work machine side, the electronic board 100 in the wireless reception control device 70 faces the worker side. The worker M can operate the wireless command device 60 with the wireless command device 60 facing the electronic substrate 100. For this reason, the radio signal transmitted from the radio command device 60 can be reliably received by the electronic substrate 100.

  Further, the control box 82 of the wireless reception control device 70 has the flange portion 84b attached to the attachment plate 71 via the packing 87, so that the opening portion 82b of the accommodating recess 82a can be liquid-tightly closed with respect to the attachment plate 71. . For this reason, the situation where water infiltrates into the accommodation recessed part 82a from between the flange part 84b and the attachment plate 71 can be suppressed.

  The electronic board 100 is disposed in the vicinity of the inside of the top plate portion 83 of the control box 82 and extends in the vertical direction along the top plate portion 83, so that the electronic substrate 100 is separated from the mounting plate 71. For this reason, even if water permeates into the accommodation recess 82a from between the mounting plate 71 and the flange portion 84b, the water flows on the mounting plate 71, so that the situation of adhering to the electronic substrate 100 can be suppressed.

  Further, as shown in FIG. 5A, the lower end of the control box 82 is provided with a through hole 88, so that moisture in the accommodation recess 82 a can be discharged, and water adheres to the electronic substrate 100. The situation to do can be suppressed more.

  Further, as shown in FIG. 1B, the control box 82 is covered with a cover 110 that surrounds the top plate portion 83 and the side plate portion 84, so that water is controlled when the tilling work machine 1 is washed. A situation of adhering to the surface side of the box 82 can be prevented. In addition, since the water flow direction changing plate 79 is provided on the back surface of the mounting plate 71, the water flowing from the upper part to the lower side of the back surface of the mounting plate 71 hits the water flow direction changing plate 79 and falls downward. Further, the lower portion of the cover 110 below the water flow direction changing plate 79 in the cover 110 extends further downward beyond the mounting plate 71. For this reason, even if the water at the time of car wash is poured on the lower back side of the mounting plate 71, the water hits the lower part of the cover 110 and bounces off. Therefore, it is possible to reduce the adhesion of water to wiring components such as the board-side connector 104 and the drive-side connector 106 arranged below the back surface side of the mounting plate 71.

  Now, FIG. 6, FIG. 7 (a) (side view), and FIG. 7 (b) (side view) show the tilling work machine 1 removed from the traveling machine body 90 and held by the caster stand 7. FIG. . The posture of the tilling work machine 1 held by the caster stand 7 is further inclined downward in the vertical direction as compared to the posture during the tilling work (see FIG. 3A). For this reason, the cover 110 covering the control box 82 has a posture extending in a substantially vertical direction, and the electronic board 100 accommodated in the control box 82 is similarly in a posture extending in a substantially vertical direction. Therefore, by operating the wireless command device 60 from the front of the tillage work machine 1 with the electronic board facing toward the electronic board, it is the same as when the operator M who has boarded the driver's seat of the traveling machine body 90 operates the wireless command device 60. In addition, the radio signal transmitted from the radio command device 60 can be reliably received by the electronic substrate 100.

  Even when the posture of the control box 82 extends in a substantially vertical direction, the surface side (the top plate portion side and the side plate portion side) of the control box 82 is covered with the cover 110, and the control box 82 is covered with the packing 87 ( Wiring components such as the board-side connector 104 and the drive-side connector 106 that are attached to the mounting plate 71 via the lower side of the control box 82 and are attached to the mounting plate 71 (see FIG. 5A) (see FIG. 1B). Is still covered by the water flow direction changing plate 79 (see FIG. 1B) and the lower portion of the extended cover 110. For this reason, it is possible to suppress the situation where water enters the control box 82 when the tilling machine 1 is washed, and to reduce the adhesion of water to the wiring components.
