The rotation control of discharging spiral conveying mechanism 12 is described.If the operator handles rotary switch SW4 and switches to the right rotation position, the right rotation control command that then will discharge spiral conveying mechanism 12 sends to controlling organization 60.Controlling organization 60 obtain from rotary switch SW4 the right rotation control command during in, drive electro-motor M so that discharge spiral conveying mechanism 12 and carry out right rotation.If the operator handles rotary switch SW4 and switches to the neutral position, the neutral control command that then will discharge spiral conveying mechanism 12 sends to controlling organization 60.Controlling organization 60 obtain from rotary switch SW4 neutral control command during in, electro-motor M is quit work.If the operator handles rotary switch SW4 and switches to left side rotating position, then will discharge the anticlockwise control command system of sending to of spiral conveying mechanism 12 and drive mechanism 60.Controlling organization 60 obtain from rotary switch SW4 the anticlockwise control command during in, drive electro-motor M so that discharge spiral conveying mechanism 12 and carry out anticlockwise.When detect the right terminal position P2 (bearing position) that discharges spiral conveying mechanism 12 by the first limit switch SW2, or when detecting the left-end point position P1 (drain position) that discharges spiral conveying mechanism 12 by the second limit switch SW3, controlling organization 60 quits work electro-motor M.Thus, the slewing maneuver scope of discharging spiral conveying mechanism 12 is set between left-end point position P1 and the right terminal position P2.
(lifting control)
The lifting control of discharging spiral conveying mechanism 12 is described.Switch to the position of standing up as if operator's operate lifting switch SW 5, the control command of standing up that then will discharge spiral conveying mechanism 12 sends to controlling organization 60.If controlling organization 60 obtains discharging the control command of standing up of spiral conveying mechanism 12 from direction switch SW5, then during the control command that obtains from direction switch SW5 standing up in, controlling organization 60 drives hydraulic cylinder CY so that discharge spiral conveying mechanism 12 and stand up.Switch to the neutral position as if operator's operate lifting switch SW 5, the neutral control command that then will discharge spiral conveying mechanism 12 sends to controlling organization 60.If controlling organization 60 obtains discharging the neutral control command of spiral conveying mechanism 12 from direction switch SW5, then obtain from direction switch SW5 neutral control command during in, controlling organization 60 quits work hydraulic cylinder CY.Switch to the lodging position as if operator's operate lifting switch SW 5, the lodging control command that then will discharge spiral conveying mechanism 12 sends to controlling organization 60.If controlling organization 60 obtains discharging the lodging control command of spiral conveying mechanism 12 from fluctuating switch SW 5, then during the control command that obtains from direction switch SW5 lodging in, controlling organization 60 drives that hydraulic pressure make cylinder CY so that discharge spiral conveying mechanism 12 lodging.When stopping and support when discharging spiral conveying mechanism 12 that by stopping that sense switch SW1 detects controlling organization 60 quits work hydraulic cylinder CY.
