[0022]
On the other hand, an engine room 41 for accommodating the engine (not shown) is formed below the seat 8, and the grain after threshing is put in a bag in the rear of the engine room 41 (driver's seat 6). A wrinkle receiving portion 42 to be packed is provided. At this time, the upper surface 41a of the engine room 41, that is, the mounting surface of the seat 8 constitutes an inclined surface 40 whose front end is inclined, and the seat 8 is detachably attached to the upper surface of the engine room 41, As shown in FIG. 9, the seat 8 removed from the engine room 41 is configured to be placed on the floor 11 of the driver seat 6.
[0023]
On the other hand, the hanger receiving portion 42 is provided with front and rear hangers 43 that support the bag, and the tip of a whipping tube 44 protruding from the threshing portion 4 is projected between the front and rear hangers 43. ing.
[0024]
In this manner, the threshing part 4 is hooked on the hanger 43 and supported in the cradle receiving part 42, and the tip of the whipping tube 44 is inserted in the vicinity of the throat of the sack bag or inserted into the throat. It is configured so that the grains can be easily moved (discharged) from the bag to the bag.
[0025]
Further, a bracket 46 is attached between the threshing portion 4 and the koji receiving portion 42 so as to be attached to the side of the milling cylinder 44, and the bracket 46 is positioned so as to be located behind the koji receiving portion 42. Left and right side clutch levers 47L and 47R for operating the left and right side clutches and a parking brake lever 48 for operating the parking brake are provided to be swingable back and forth via the same fulcrum shaft 45.
[0026]
That is, as shown in FIGS. 5 and 8, the base end side of the right side clutch lever 47R and the link arms 23 and 24 for the right side clutch are connected via the wire 51, and the left side The base end portion side of the clutch lever 47L and the link arms 21 and 22 for the left side clutch are connected via the wire 52, and either the left or right side clutch lever 47L or 47R is swung rearward. As a result, either the left or right side clutch is disengaged and actuated via the wire 51 or 52 and the link arms 21, 22 or 23, 24, and the body 2 is steered.
[0027]
As shown in FIGS. 6 and 8, the base end side of the parking brake lever 48 and the operation arm 33 are connected via a wire 53, and the parking brake lever 48 is swung rearward. Thus, the operation arm 33 can be swung via the wire 53, and the parking brake can be operated by operating the brake lever 36 of the parking brake.
[0028]
As described above, the steering of the airframe 2 can be operated by operating the left and right side clutch levers 47L and 47R, and the stop of the airframe 2 can be operated by operating the parking brake lever 48. That is, a rear operation section (second operation section) 54 including side clutch levers 47L and 47R, a parking brake lever 48, and the like is provided behind the driver's seat 6 (the saddle receiving section 42). It is possible to control the airframe 2 by the above.
[0029]
At this time, the levers 47L, 47R, 48 of the rear operation unit 54 are provided at positions where the operator can stand up and operate, so that the operator can hold the airframe 2 in a standing posture standing by the rear operation unit 54. A riding type combine that can be steered and that controls the airframe 2 while sitting on the seat 8 can be used as a walking type.
[0030]
On the other hand, a side operation panel 56 is arranged between the seat 8 and the threshing unit 4 from the side of the preprocessing unit 3 to the side of the threshing unit 4. Various levers for operation are projected. In the present embodiment, the side operation panel 56 and the front operation panel 7 are separated and independent, and a space S is formed between the two panels.
[0031]
Thus, as described above, when the operator steers the combiner in the standing posture by the rear operation unit 54, the rear operation is performed so that the operator can visually recognize the position of the divider 3 b provided in front of the preprocessing unit 3. A gap is formed from the upper side of the section 54 to the divider 3b in front of the seat 8, and the operator can easily operate the combine while confirming the position of the divider 3b by the line of sight L1.
[0032]
In particular, the seat 8 can be attached and detached, and when the seat 8 is removed, the upper surface 41a of the engine room 41 is inclined forward to form the inclined surface 40, which is not necessary when used as a walking combine. When the seat 8 is removed and handled as a walking combine, the divider 3b can be easily confirmed, the combine operability is high, and the combine can be easily operated from the rear operation unit 54.
[0033]
As described above, even when the operator steers the combine in the sitting posture by using the front operation unit 13, the operator can visually recognize the position of the divider 3b by using a part of the gap (space S). The operator can easily operate the combine while confirming the position of the divider 3b by the line of sight L2.
[0034]
On the other hand, in the case of the present embodiment, the main transmission lever 57 as the lever arranged on the side operation panel 56 is turned on to the side of the preprocessing unit 3 (the front side of the seat 8) and the operations of the threshing unit 4 and the preprocessing unit 3 are turned on. Clutch levers 58 for cutting are provided on the side of the threshing section 4 (on the rear side of the seat 8).
[0035]
At this time, the clutch lever 58 is swingable back and forth, and the main speed change lever 57 is swingable back and forth or back and forth and left and right. The main speed change lever 57 rotates the rotation direction and the number of rotations (running speed). And the front and rear traveling directions) can be switched by the clutch lever 58 between the operations of the pretreatment unit 3 and the threshing unit 4.
[0036]
That is, the clutch lever 58 is operated by oscillating the threshing unit 4 by a predetermined angle from the stopped state of the pretreatment unit 3 and the threshing unit 4, and further by oscillating the threshing unit 4 by an oscillation angle that activates the threshing unit 4. A clutch for switching the operation of the threshing unit 4 and the preprocessing unit 3 is linked to operate the preprocessing unit 3.
[0037]
In addition, since the structure of the one clutch lever 58 which switches the action | operation of the pre-processing part 3 and the threshing part 4 is conventionally well-known, detailed description is omitted. Further, since a mechanism for adjusting the rotation direction and the number of rotations of the output from the engine side by the main transmission lever 57 is also known in the art, a detailed description thereof will be omitted.
[0038]
The clutch lever 58 is disposed between the front operation unit 13 and the rear operation unit 54 as described above. When the operator controls the airframe 2 by the front operation unit 13, the operator sitting on the seat 8. If the operator slightly extends his / her hand to the rear, and the operator steers the airframe 2 by the rear operation unit 54, the operator can extend the hand slightly to the front, so that the operator can control the operation by the operation units 13 and 54. It is possible to operate the clutch lever 58 at the same time.
[0039]
On the other hand, the main transmission lever 57 is pivotally supported in a forward / backward swing, and has a structure in which the travel speed and the forward / backward travel direction can be set and adjusted by the forward / backward swing as in the prior art. The fulcrum shaft 55 of the main transmission lever 57 is attached to a counter 60 that is attached to the transmission 14 side and outputs the driving force from the engine separately to the drive system and the pre-processing unit system via a bracket 65.
[0040]
Further, the side panel 56 is fixed to the threshing portion cover 70 side and the floor 11 side, the support structure of the main transmission lever 57 and the side panel 56 is simplified, and the airframe is also reduced in weight.
[0041]
On the other hand, in the present embodiment, a tachometer 75 that displays the rotation of the threshing unit 4 (cylinder) is disposed behind the seat 8 and between the seat 8 and the rear operation unit 54, and the right side of the threshing unit 4. It is attached to the wall side. As a result, the operator can easily check the tachometer 75 when operated by the front operation unit 13 (when used as a riding combine) and when operated by the rear operation unit 54 (when used as a walking combine). It is possible to easily check whether the threshing portion side maintains an appropriate rotation in accordance with the type of grain in both operation postures.
[0042]
Since the combine of this invention is comprised as mentioned above, when an operator steers the airframe 2 by the front operation part 13 in a farm field (a mowing threshing work driving | running | working), an operator is seated on the seat 8 and an engine is operated. The airframe is operated by lowering the preprocessing unit 3 by the multi-control lever 9 and operating the threshing unit 4 by the clutch lever 58 and by operating the preprocessing unit 3 and swinging the main transmission lever 57 forward. 2 travel is started.
[0043]
The body 2 can be steered by swinging the multi-operation lever 9 left and right. Further, when the operator depresses the parking brake pedal 12, the preprocessing unit 3 can be stopped and the parking brake can be operated to stop the airframe 2. In other words, this combine is used as a riding combine.
[0044]
On the other hand, when the operator steers the body 2 in the field by the rear operation unit 54 (runs the cutting and threshing operation), the parking brake lever 48 is first swung backward to stop the preprocessing unit 3 and activate the parking brake. In this state, the engine is operated by moving to the front control unit 13 side, the pre-processing unit 3 is lowered by the multi-operation lever 9, and the main transmission lever 57 is swung forward.
[0045]
And it moves to the back operation part 54 side, operates the clutch lever 58 in a standing posture, operates the threshing part 4, operates the pre-processing part 3, and rocks the parking brake lever 48 forward, and the parking brake. The work travel of the airframe 2 is started by canceling. At this time, the airframe 2 can be steered by swinging the left and right side clutch levers 47L and 47R.
[0046]
Further, when the operator swings the parking brake lever 48 backward, the preprocessing unit 3 can be stopped and the parking brake can be operated to stop the machine body 2. That is, this combine is used as a walking combine.
[0047]
In addition, the above-described operation example using the front and rear operation units 13 and 54 is for operation traveling (reaping and threshing the rice cake while running), but the threshing unit 4 and the preprocessing unit are operated by operating the clutch lever 58. By stopping the operation of 3, the vehicle body 2 can be simply driven (without working).
[0048]
As a result, by using the combine as a walking type (steering by the rear operation unit 54 in a standing posture), it is possible to easily move a relatively narrow steep agricultural road in a mountainous area, work on a relatively narrow field, etc. In particular, the front operation unit 13 is arranged on the side of the pre-processing unit 3, the seat 8 is arranged behind the front operation unit 13, and the rear operation unit 54 is arranged behind the seat 8 (the heel receiving unit 42). Is located on the rearmost side of the airframe 2, and the combine is relatively compact with a total width of about 1.2m, a total length of about 2.3m, and a total height of about 1.3m. Can be performed more easily.
[0049]
Since the clutch lever 58 is disposed between the operation sections 13 and 54 and can be operated by the operator regardless of whether the combine is used as a walking type or a riding type, the Even when the combine is used as a walking type (steering is performed by the rear operation unit 54), the operations of the pre-processing unit 3 and the threshing unit 4 can be operated. Can be operated, and is configured to have high maneuverability when used as a walking combine.
[0050]
Furthermore, by providing a parking brake operation part (the parking brake lever 48 and the parking brake pedal 12) on both the front and rear operation parts 13, 54, the parking brake can be operated by both the operation parts 13, 54. When used as a combine, by operating the parking brake lever 48, an emergency stop or the like can be performed, and the operability as a walking type is further improved.
[0051]
Note that the combine transmission 14 of the present invention steers the vehicle body 2 by cutting the side clutch of the traveling device 1 inside the turn during turning by turning the multi-control lever 9 left and right or by turning the left and right clutch levers 47L and 47R back and forth. However, when the multi-operation lever 9 and the left and right clutch levers 47L and 47R are further swung from the swing angle when the side clutch is disengaged, the traveling device 1 on the inside of the turn is braked.
[0052]
As a result, the airframe 2 can be turned (steered) with a smaller turning radius. At this time, both the clutch levers 47L and 47R are swung in the rear operation portion 54 and both the traveling devices 1 are braked. The airframe 2 is also configured to stop and obtain the same effect as the parking brake.
[0053]
Since the parking brake pedal 12 is urged to the initial posture by the return spring 38 as described above, it automatically returns to the initial posture when the stepping operation is released. Therefore, on the side of the parking brake pedal 12, a lock pedal 61 that locks the parking brake pedal 12 in the depressed state is provided in the vicinity of the fulcrum shaft 32 of the parking brake pedal 12 and is pivotally supported on the corner frame 20 side. The parking brake pedal 12 is depressed by the lock pedal 61 and locked in a posture to hold the airframe 2 in a stopped state.
[0054]
That is, the parking brake pedal 12, the lock pedal 61, the return spring 38, and the parking brake-related wires 34, 37, 53, and the like are concentrated on the corner frame 20, so that the attachment of each part can be easily performed. In addition to being able to be performed, the number of mounting members and the like is reduced, which is advantageous for reducing the weight of the machine body 2.
[0055]
FIG. 10 is a rear view of the combine according to the present embodiment. In the present embodiment, the battery 80 is disposed on the upper right side of the dust removal chamber 81 in the threshing portion 4, and the body 2 is configured compactly. By arranging the relatively heavy battery 80 at the above position, the front / rear and left / right balance of the airframe 2 is well maintained, and the running performance is improved.
[0056]
【The invention's effect】
According to the structure of the present invention configured as described above, the operator can visually recognize the divider from the rear operation unit through the gap from the upper side of the rear operation unit to the divider in front of the seat. When handling by the rear operation unit as a walking type, the operator can confirm (view) the position of the divider in the steering posture (standing posture), the combine operability is high, and the combine operability from the rear operation unit is high. There is an effect that maneuvering becomes easy.
[0057]
Also, by detachably attaching the seat, removing the seat at the time of maneuvering using the rear operation unit, a relatively large gap is formed in front of the rear operation unit, and the field of view on the divider side becomes wider. The tip portion of the divider can be confirmed more easily, and the maneuverability is further improved.
