    Abstract: PURPOSE:To provide a lifting and lowering apparatus of a reaping working machine capable of previously preventing trouble of a reaping working part from lifting and lowering in a direction opposed to will of an operator by error of operation in a state in which the reaping working part is located at the intermediate position in a lifting and lowering range regardless of having the advantage capable of carrying out lifting and lowering operation of the reaping working part by a simple apparatus. CONSTITUTION:This lifting and lowering apparatus of a reaping working machine is equipped with a hydraulic cylinder 9 for driving, lifting and lowering a reaping working part and a controller 18 for controlling the hydraulic cylinder 9. The lifting and lowering apparatus is provided with an automatic lifting and lowering switch SW for giving order for lifting and lowering to the controller 18 and a lifting and lowering position sensor 22 for detecting lifting and lowering position of the reaping working part and the hydraulic cylinder 9 is controlled so as to raise the reaping working part to raising target position when order is given by the automatic lifting and lowering switch SW from a time when the lifting and lowering position of the reaping working part detected by the lifting and lowering position sensor 22 is in the set range for reaping operation and a plant foot sensor S detects to change over from reaping working state to non-working state until set time is passed.

    Abstract: PURPOSE:To provide an elevator of a reaping working machine, capable of efficiently performing elevation operation of a reaping working unit while reducing troublesome labors. CONSTITUTION:This elevator unit of a reaping working machine is equipped with a hydraulic cylinder 9 for driving and elevating a reaping working unit, an elevation control lever capable of freely switching between an elevation position for ordering elevation, a lowering Position for ordering descent and a neutral position for ordering stop of elevation and a control unit 18 for controlling elevation of the hydraulic cylinder 9 based on a switch operation of the elevation control lever. In this elevator unit, a control unit (SW) for direction of automatic elevation capable of giving a direction for automatic elevation is attached to the grip part of the elevation control lever so that it may be operated with the fingers. The control unit 18 is designed so that it may perform an automatic elevation control for controlling the hydraulic cylinder 9 so as to automatically elevate the reaping working unit up to a preset target elevation position based on an automatic elevation direction from the control unit (SW).

    Abstract: PURPOSE:To normally carry out reverse drive of a fan in the reverse drive of the fan by energizing a switching member onto a normal rotation position side, operating the switching member to a reverse rotation position against the energizing force to be pressed and energized onto a transmission belt so as to maintain tension of the transmission belt. CONSTITUTION:When a switching member 16 is operated in a normal rotation position, tension of a transmission belt 14 is maintained by two of a normal rotation pulley 17 and a tension pulley 15, so that the tension of the transmission belt 14 is surely maintained without affected by vibration even when the transmission belt 14 is vibrated according to the rotation. Inversely, when the switching member 16 is operated by an operation means 26, the tension pulley 15 in another position is pressed onto a transmission belt 14 while the transmission belt 14 is pressed by a reverse rotation pulley 18, even though operation quantity of the operation means 26 to the reverse rotation position B is fixed. In this way, in the reverse rotation position B, the tension pulley 15 follows up and the tension of the transmission belt 14 can be maintained without affected by the vibration, even though the transmission belt 14 is vibrated according to the rotation.

    Abstract: PURPOSE:To provide a combine harvester enabling cloggings of grain culms being in conveyance to be easily removed. CONSTITUTION:In a combine harvester designed that reaped grain culms are conveyed toward a thresher, their feet are held by a holding conveyer 8 and conveyed, during which their ear tips are threshed inside the thresher, a device A is equipped so as to be switchable for the holding conveyer 8 between (a) holding action mode with which reaped grain culms can be conveyed and (b) holding release mode with which the hold of reaped grain culm feet are released, and an another sensor 30 is also equipped so as to detect cloggings of grain culms being in conveyance at the holding conveyer 8; and, when the sensor 30 is actuated, the device A is controlled to switch from the mode a to the mode b.

    Abstract: PURPOSE:To provide an engine cooling device having a mechanism capable of easily removing dust passing through a dust protection net and adhering to the cooling fin of a radiator without any need of a troublesome cleaning work. CONSTITUTION:A dust protection net 14 is fitted to an intake duct 11 for drawing the fresh air on the operation of a cooling fan 10 for a radiator 9, thereby constituting a fresh air intake section 13. A perforated plate 15 having a plurality of draft holes for evenly supplying the air drawn via the section 13 to the radiator 9 is laid at the immediate front thereof. In addition, a shutter plate 16 freely selectable between ventilation mode for allowing the suction of the fresh air through the holes of the plate 15 and screening mode for prohibiting such air suction is provided in such state as nearly superposed on the plate 15.

    Abstract: PURPOSE:To carry out uniform and quick discharge of grains from a grain tank by placing an adjustment plate in a specific state to form a gap between the bottom of the grain tank and the plate. CONSTITUTION:An adjustment plate 18 is placed to form gaps La, Lb between the plate and the bottom face 7 of a grain tank 3. The gap is widened toward the downstream side in the delivery direction of a grain delivery screw 5 to eliminate the difference of the grain delivery speed in the direction of the length of the screw 5. The gap Lb is made to be wider than the gap La to increase the flow-down rate of grains near an auxiliary tank 8. The level of stored grains can nearly uniformly be decreased in the whole grain tanks.
