' respectively.

Further, a support shaft 25 is provided in the upper interior of the control column 18 in the lateral direction.
The boss portions 26 and 26' of both side clutch levers 23 and 23' are rotatably installed on the support shaft 25, and the arm 27 extending from each boss portion 26 and 26' is provided with a side clutch actuator. Spring wires 28 and 28' are connected to each other.

Boss portions 29 of the levers b and a are provided at both ends of the support shaft 25. 30 are attached freely to rotate, and two bent interlocking rods 32 . 32' are connected respectively, and the interlocking rod 3
A connecting rod 33 is connected to 2', and a spring wire 34 for operating the tension pulley 16 is connected to the other connecting rod 32. When the threshing clutch lever b is rotated forward, the spring wire 34 and When the connecting rod 33 is pulled upward, the threshing transmission part B is operated to engage the clutch by the spring wire 34, and when the threshing clutch lever b is operated backward, the clutch is disengaged.

A bending interlocking rod 36 is connected to the intermediate portion of the reaping clutch lever a via a pin 35, and the interlocking rod 36
A spring 37 is connected to the lower end, and when the reaping clutch lever a is rotated forward, the spring 37 is pulled upward to engage the clutch, and when operated backward, the clutch is disengaged. An actuating portion D is connected between the wire 38 for actuating the -15, the connecting rod 38, and the spring 37.

That is, the actuating portion D includes arm portions 3 extending upward at both ends of an actuating plate d having a horizontally elongated hole 42 in the center.
9. 39', the lower end of the connecting rod 33 is connected to one arm part 39', the lower end of the spring 37 is connected to the other arm part 39, and the U connected to the upper end of the wire 38 is connected. The connecting pin 41 of the shaped link 40 is movably inserted into the elongated hole 42, and both levers a,
The structure is such that the reaping actuator A is operated to engage the clutch via the actuator D only when the actuators b are operated to engage the clutch at the same time.

In addition, in the figure, 43 is a battery box, 44 is a storage part of a tool box, 45 is a rearview mirror, and 46 is a straw removal chain.

Therefore, during combine harvesting work, the clutch of the traveling transmission section C can be operated by operating the tension pulley 12, but even if the clutch of the reaping transmission section A is engaged, if the clutch of the traveling transmission section C is disengaged. , the reaping transmission section A automatically enters a transmission-stop state.

Further, when the threshing clutch lever b is operated to engage the clutch, the spring wire 34 and the connecting rod 33 are pulled upward, and the spring wire 34 operates the tension pulley 16 to operate the threshing transmission part B to engage the clutch. When the threshing clutch lever b is turned backward to disengage the clutch, the threshing transmission section B can be operated to disengage the clutch.

By operating the reaping clutch lever a, the clutch of the reaping transmission section A can be operated, but both levers a and l)
When the clutch is disengaged, as shown in FIG. 8, the position of the connecting pin 41 that fits into the long hole 42 of the actuating plate d is at the clutch disengagement position A, and the reaping transmission section A is in the clutch disengaged state. As shown in Fig. 9, even if the reaping clutch lever a is engaged and the spring 37 is pulled upward, if the threshing clutch lever b is in the clutch disengaged state, the connecting pin 41 is moved by the slight inclination of the operating plate d. As a result, the reaping transmission section A is in a state where it is not operated to engage the clutch even if the clutch is slightly raised from the clutch disengaged position A.

In addition, as shown in FIG. 10, when the threshing clutch lever b is engaged and the connecting rod 33 is raised, and the reaping clutch lever a is in the clutch disengaged state, the position of the connecting pin 41 will not change much. Transmission part A maintains the clutch disengaged state.

When both levers a and b are operated to engage the clutch, the spring 37 and the connecting rod 33 are pulled upward, and the first
As shown in FIG. 1, the connecting pin 41 is pulled upward to the clutch disengaged position A, and the reaping transmission section A can only be operated to engage the clutch while the wire 38 is being pulled upward.

That is, the transmission state of the reaping transmission section A is influenced by the clutch operation of the traveling transmission section C, the threshing transmission section B can be independently operated as a clutch by operating the threshing clutch lever b, and the clutch disengagement operation of the reaping transmission section A can be performed independently. can be performed by the reaping clutch lever a, but the clutch engagement operation can be performed by the clutch engagement operation of the reaping clutch lever a only when the threshing clutch lever b is in the clutch engagement state, Each operation allows you to operate the combine harvester during work or inspection.

In this way, the present invention allows driving mission 1 to be started from engine E.
The traveling transmission section C moves the traveling mission 1 to the reaping section 2.
The structure is such that power is transmitted from the engine E to the threshing part 3 by the threshing transmission part A, and from the engine E to the threshing part 3 by means of clutches that can be freely disconnected. When both the reaping clutch lever a and the threshing clutch lever b are engaged, the clutch of the reaping transmission section A is engaged, but when only one of the levers a and l) is engaged, the clutch of the reaping transmission section A is engaged. Since the structure is such that the threshing clutch lever b side is connected to the operating system of the reaping clutch lever a side via the actuating part D so that it does not operate when the threshing clutch lever b side is activated, the interlocking relationship between the traveling part and the reaping part 2 is facilitated and reaping is possible. If the machine stops during work, the reaping unit can be safely stopped by stopping the running unit without causing clogging due to entanglement of culms, etc., and the clutch of the threshing transmission unit A can be operated independently. It can be operated or stopped independently when a problem occurs or when an inspection is performed.

In the power transmission of the reaping section 2, the clutch can be disengaged by operating the reaping clutch lever a, but the clutch cannot be engaged unless the threshing clutch lever b is engaged. The third aspect of the present invention is to operate in a state where safety can be ensured, so that combine harvester work and inspection and repair of various parts can be carried out safely and favorably.
