By providing the control lever, engine rotation adjustment by the engine control lever and a series of shifting operations of the auxiliary transmission lever and the main transmission lever can be performed efficiently and smoothly with one hand. In addition, since the engine control lever is not provided on the front control panel unlike the conventional one, it is possible to prevent the engine control lever and the knee from coming into contact with each other when the operator is driving in a standing posture. .

  In addition, by installing the working unit lever behind the auxiliary transmission lever via the engine control lever, when the pretreatment unit or the threshing unit is clogged with cereals, the working unit lever is used as the auxiliary transmission lever. It can be operated immediately without being interrupted.

  In addition, a space is formed behind the main shift lever and closer to the inside of the engine control lever and the working unit lever, and an automatic control operation panel unit is provided. It can be easily performed directly under the side of the operator without being obstructed, and erroneous operation of the switches of the combine work automatic control device having a high operation frequency can be prevented. In addition, since a wide space is formed on the side of the driver's seat via the automatic control operation panel unit, it is possible to easily perform the rearward confirmation and the like.

  An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a combine equipped with the engine control lever 2 according to the present invention shown in FIG. 2 and FIG. 3 in the control unit structure, and a conventional machine base 1b equipped with a crawler type traveling device 1a Similarly, the working units such as the pretreatment unit 3 and the threshing unit 5 are arranged in the front-rear direction, and the control unit 6 and the Glen tank 7 are arranged on the right side of the threshing unit 5 behind the preprocessing unit 3. An engine 9 is mounted in an engine cover 8 a that supports the driver seat 8.

With this configuration, the planted cereal is harvested by the pre-processing unit 3, and the harvested cereal is transported and supplied to the threshing unit 5, and the cerealed and threshed grain is accommodated in the glen tank 7, and the accommodated grain is The grain discharge auger 7a is operated and discharged out of the machine.
The control section 6 of the combine 1 includes a front control panel section 11 standing on the front side of the control step 10 and a side control panel section 12 standing in the front-rear direction on the left side of the control step 10 and the driver seat 8. Is configured in an L shape in plan view.

  The front steering panel 11 has a column-shaped upper part, and a steering wheel 13, a monitor device 13a, and an aircraft horizontal control operation unit 13b arranged in a row from the right side to the left side, and a traveling clutch pedal 14 is disposed below the monitor device 13a. doing. Although the steering 13 in the illustrated example is a steering operation lever system, it can also be a rotating handle system.

  The side control panel unit 12 is formed behind the main transmission lever 15 with a main transmission lever 15 and a sub transmission lever 16 that are operated in the front-rear direction on the front side of the panel 21 to be described later. The automatic control operation panel unit 17 is arranged on a square panel surface in a space where the engine control lever 2, the pre-processing unit 3 and the threshing unit 5 are clutched behind the auxiliary transmission lever 16. The part lever 19 and the like are arranged so as to form a series of linear operation flow lines. In addition, the soot processing operation part 20 such as the soot processing lever for operating the Glen tank 7 and its grain discharge auger 7a, etc., and the waste transport switching lever 20a are installed on the rear side of the driver's seat 8 like the conventional one. ing.

  The panel 21 serving as a cover frame of the side control panel 12 is formed as a flat upper wall surface by a plate member. A main transmission lever guide groove 22, an auxiliary transmission lever guide groove 23, an engine control lever guide groove 25, and a working portion lever guide groove are inserted into the upper surface of the panel 21 to guide the operation in the front-rear direction through the levers. 26 is drilled.

The main transmission lever guide groove 22 is formed by a crank groove-shaped long hole, and as shown in FIG. 3, the central step portion of the crank groove is set to the neutral position, and the main transmission lever 15 connected to a transmission (not shown) from here is connected to the front side and the rear side. When the vehicle is operated to the side, the vehicle speed is changed to forward speed change and reverse speed change according to the operation amount.

If it operates, it can be set as the working part stop state which stopped the threshing part 5 with the pre-processing part 3. FIG.

In the lever structure as described above, the engine control lever 2 installed between the auxiliary transmission lever 16 and the working unit lever 19 is longer than the auxiliary transmission lever 16 and the working unit lever 19 so as to protrude upward from the panel 21. It is shortened.
Accordingly, the engine control lever 2 that is less frequently operated is lowered between the auxiliary transmission lever 16 and the working unit lever 19, and the interval between the auxiliary transmission lever 16 and the working unit lever 19 is substantially increased. As a result, when operating the working unit lever 19 having a high operation frequency or the sub-transmission lever 16 having a slightly low operation frequency, the operation control lever 2 can be easily identified and the erroneous operation can be prevented.

Further, as shown in FIG. 2, when the engine control lever 2 is at the work rotation position A and the work part lever 19 is operated to the front side and the pretreatment part 3 and the threshing part 5 are in the powered work position, the engine control lever 2 And the working unit lever 19 are close to each other, and the engine control lever 2 and the auxiliary transmission lever 16 are separated from each other.
As described above, when the engine control lever 2 is at the work rotation position A and the work part lever 19 is at the work position, both levers are close to each other, but the work part lever 19 is longer than the engine control lever 2 and therefore the engine The control lever 2 can be operated without being obstructed.

  On the other hand, the automatic control operation panel portion 17 is disposed behind the main transmission lever 15 and on the side (inward side) of the engine control lever 2 and the working portion lever 19, and is located directly below the side of the operator in the vicinity of the driver seat 8. Installed. The automatic control operation panel unit 17 includes sensor switches for various automatic operation of combine operations such as automatic handling depth, automatic direction, automatic sorting, and horizontal control of the machine, and various switches and volumes. An operation tool, a monitor, and the like are arranged in a compact manner on a substantially flat surface. A wide space is formed above the automatic control operation panel 17 between the levers and the driver seat 8.

  When the engine 9 is started, the combine 1 having the control unit 6 configured as described above first sets a secondary shift of the auxiliary transmission lever 16 and then operates the engine control lever 2 to rotate the engine. Adjust to work rotation. Next, in a state in which the working unit lever 19 is turned on and operated, the operation of the main transmission lever 15 and the like are performed in series, and the combine work is started.

  In this combining operation, the main transmission lever 15 and the auxiliary transmission lever 16 are juxtaposed so as to be operable in the front-rear direction on the inner side and the outer side of the front part of the side operation panel 12 of the control unit 6. Since the engine control lever 2 that adjusts the engine rotation by operating in the front-rear direction is provided on the rear side, it is possible to avoid the installation of the engine control lever 2 on the front control panel 11 side as in the prior art.

  Therefore, when the operator stands up in the maneuvering step 10 or rides forward from the driver's seat 8, the front maneuvering panel unit 11 has no fear of bringing the operator's knee into contact with the engine control lever 2. In addition, it is possible to smoothly perform the driving operation without causing an erroneous operation that causes the engine rotation to be changed inadvertently or knee injury.

  In addition, the working unit lever 19 installed behind the auxiliary transmission lever 16 via the engine control lever 2 is operated at a work rotation position A at an emergency stop when the pretreatment unit 3 or the threshing unit 5 is clogged with cereals. Without being obstructed by the engine control lever 2 and the auxiliary transmission lever 16 and the like, the operation can be immediately performed and the working portion can be reliably stopped.

  Even if the hand accidentally touches the engine control lever 2 during the operation of cutting only the pre-processing unit 3 with the working unit lever 19, the engine control lever 2 rotates the working unit lever 19 in the cutting direction. Since the position A is set, the threshing operation can be continued because the engine rotation is not rotated at a low speed.

  Further, an automatic control operation panel unit 17 disposed in a space formed behind the main transmission lever 15 and on the side of the engine control lever 2 and the working unit lever 19 is brought close to the driver seat 8 and directly below the side of the operator. Therefore, it is possible to perform the operation of each switch quickly and without error without being obstructed by the various levers, and the visual check of the switches of the combine operation automatic control device with high operation frequency is ensured. it can.

  In addition, since the space above the automatic control operation panel 17 is a large space, the operation lever 19 and the like can be quickly operated, and the main transmission lever 15 and the like that are frequently operated on the left front side can be quickly operated. Or when the body is twisted to check backwards or when operating the rear heel processing operation unit 20 or the like, the fear of contacting the elbow or the like with the engine control lever 2 or the working unit lever 19 or the like can be eliminated. .

  Further, the engine control lever 2 without the engine control lever 2 on the front control panel unit 11 side and provided with the engine control lever 2 on the side control panel unit 12 side according to the above-described configuration is used for the vehicle speed and the left hand during the combine operation. A series of lever operations of the work is performed smoothly with the left hand with a substantially straight operation flow line without unnecessary operations, and the right hand can be dedicated to the steering operation, facilitating the steering operation. The working unit lever 19 is not limited to the illustrated example, and a pretreatment working unit lever and a threshing working unit lever may be provided in parallel as in the conventional example.

It is a side view of the combine provided with the control part structure of this invention. It is an enlarged side view which shows the structure of the control part of FIG. FIG. 3 is a plan view of FIG. 2.
