  Usually, in order to perform a harvesting operation along the grain row, the worker advances the aircraft while visually checking a divider arranged on the outermost side of the aircraft. However, since the combine described in Patent Document 1 raises the headlamp and the work lamp and arranges them above the apparatus, the headlamp and the work lamp are moved upward from the upper cover that covers the lateral transmission cylinder of the pretreatment unit. Or it was the structure which protrudes ahead largely. For this reason, when an operator sits in the cabin, the projecting headlamps and work lamps that protrude greatly interfere with each other, and there is a problem in the visibility of the divider.

  Then, this invention aims at providing the combine which has arrange | positioned so that the protrusion amount to the upper direction or the front of a work lamp may be suppressed, and has solved the subject mentioned above.

  Here, the arrangement of the headlamp 22 and the work lamp 23 of the left light unit 20 and the headlamp 26 and the work lamp 27 of the right light unit 21 will be described in detail. First, the left light unit 20 will be described. In the following description, of the five pulling devices 12,..., The pulling device arranged on the outermost side in the left-right direction is referred to as the outermost pulling device, and in particular in FIG. The arranged raising device is called the leftmost raising device 12L, and the raising device arranged on the rightmost side is called the rightmost raising device 12R.

  As shown in FIG. 4, the left light unit 20 has a center line C1 (center) above the leftmost pulling device 12L (outermost pulling device) and in the left-right direction of the leftmost pulling device 12L. Part) outside the fuselage. The headlamp 22 of the light unit 20 is disposed so as to overlap the leftmost pulling device 12 </ b> L in the left-right direction and on the outer side of the fuselage 39 in the left-right direction than the transmission cylinder 39. The work lamp 23 is disposed outside the machine body in the left-right direction of the leftmost pulling device 12 </ b> L and the lateral transmission cylinder 31. Moreover, the work lamp 23 is arrange | positioned behind the headlamp 22 (refer FIG. 6).

  The area of the reflector 22 a of the headlamp 22 is set larger than the area of the reflector 23 a of the work lamp 23. Further, as shown in FIG. 5A, the socket 22c into which the light main body 22b of the headlamp 22 is screwed is lower than the axial center of the lateral transmission shaft 32 and more than the leftmost pulling device 12L. It is arranged above. As shown in FIG. 5A, the socket 22 c of the headlamp 22 is arranged at a position where it does not interfere with the connection case 36 and the transmission gear case 35, and is located on the side of the transmission cylinder 39 in a side view. Yes.

  Next, the right light unit 21 will be described. As shown in FIG. 4, the right light unit 21 is located above the rightmost pulling device 12R (outermost pulling device) and on the center line C2 (center of the rightmost pulling device 12R in the left-right direction). Part) outside the fuselage. The headlamp 26 of the light unit 21 is disposed on the outer side of the fuselage 39 in the left-right direction so as to overlap with the rightmost pull-up device 12 </ b> R in the left-right direction. The work lamp 27 is disposed outside the machine body in the left-right direction of the rightmost pulling device 12 </ b> R and the lateral transmission cylinder 31. The work lamp 27 is disposed behind the headlamp 26.

  The area of the reflector 26 a of the headlamp 26 is set larger than the area of the reflector 27 a of the work lamp 27. Further, as shown in FIG. 5B, the socket 26c into which the light main body 26b of the headlamp 26 is screwed is lower than the axial center of the lateral transmission shaft 32 and more than the rightmost raising device 12R. It is arranged above. As shown in FIG. 5B, the socket 26 c of the headlamp 26 is disposed at a position where it does not interfere with the support frame 37 and beside the transmission cylinder 39 as shown in FIG.

  Next, the irradiation directions of the headlamps 22 and 26 and the work lamps 23 and 27 will be described. However, since the left light unit 20 and the right light unit 21 are substantially bilaterally symmetric, Only the irradiation direction of the work lamp 23 will be described. As shown in FIGS. 6 and 7, the headlamp 22 irradiates light in the direction of arrow F toward the front and slightly below the pretreatment unit 5. The work lamp 23 emits light toward the periphery of the divider 11 arranged on the leftmost side, outward of the machine body, and forward and downward, that is, in the direction of the arrow W. Since the light main body 22b of the headlamp 22 and the light main body 23b of the work lamp 23 are mounted in the same direction, irradiation is performed depending on the orientation and shape of the reflector 22a of the headlamp 22 and the reflector 23a of the work lamp 23. The direction, that is, the directions of arrows F and W are defined. Since the light main bodies 22b and 23b are attached in the same direction, the attachment / detachment workability can be improved.

  As shown in FIG. 7, a substantially half-moon-shaped recess 17 a is formed in the side cover 17 immediately below the work lamp 23. The concave portion 17a is formed so as not to prevent light irradiation in the direction of the arrow W of the work lamp 23, can reliably illuminate the periphery of the leftmost divider 11, and improves the visibility of the divider 11. Can do. The recess 17a is provided with a lock handle 17b, and the side cover 17 can be easily attached and detached by operating the lock handle 17b. The side cover 17 on the right side surface of the pretreatment unit 5 is similarly provided with a recess 17a and a lock handle 17b, and of course has the same effect.

  Since this Embodiment consists of the above structures, an operator sits on the driver's seat in the cabin 6, operates the combine 1, and performs the harvesting / threshing work of the cereal. The operator turns on the left and right light units 20 and 21 when sunset approaches during the work.

  By turning on the headlamps 22 and 26, the front visibility of the preprocessing unit 5 can be improved. Then, by turning on the work lamps 23 and 27, the visibility of the leftmost and rightmost dividers 11 and 11 can be improved, and the cutting operation can be efficiently performed in accordance with the grain row. At this time, since the concave portion 17a is formed in the side cover 17, the left and right dividers having poor visibility for the worker who has entered the cabin 6 can illuminate directly below the work lights 23 and 27. 11 and 11 can be reliably illuminated.

  Moreover, since the right and left light units 20 and 21 are disposed above the plurality of pulling devices 12,..., The left and right light units 20 and 21 are attached to a relatively long grain pod extending from the field or the mounting portion 41 of the pulling device 12. The visibility of the divider 11 and the front can be improved without obstructing the irradiation of light by the auxiliary pulling device. Then, when the side covers 17 and 17 are removed by operating the lock handle 17b of the side cover 17, the left and right light units 20 and 21 are positioned so as not to interfere with the leftmost pulling device 12L and the rightmost pulling device 12R. Since it is arranged, maintenance such as replacement of the light main bodies 22b, 23b, 26b, and 27b can be easily performed.

  The left and right light units 20 and 21 are arranged outside the fuselage from the center lines C1 and C2 of the leftmost and rightmost pulling devices 12L and 12R. More specifically, the headlamps 22 and 26 are respectively leftmost. In addition, the right and left pulling devices 12L and 12R are arranged so as to overlap in the left-right direction, and the work lamps 23 and 27 are arranged in the left-right direction with respect to the left-most and right-most pulling devices 12L and 12R and the lateral transmission cylinder 31, respectively. Therefore, the protrusions of the light units 20 and 21 in the forward and upward directions can be reduced while reducing the width of the airframe and having a compact structure. Thereby, the operator seated in the cabin 6 can visually recognize the leftmost and rightmost dividers 11 and 11 without being obstructed by the light units 20 and 21, and the visibility of the divider can be improved. .

  Further, since the sockets 22c and 26c of the headlamps 22 and 26 are disposed below the lateral transmission shaft 32 of the lateral transmission cylinder 31 and are pulled up to avoid the transmission cylinder 39 laterally, these lateral transmissions are performed. The protrusions forward and upward of the light units 20 and 21 can be reduced without interfering with the cylinder 31 and the raised transmission cylinder 39 while being close to each other. More specifically, the socket 22c of the left headlamp 22 is raised and disposed at a position surrounded by the transmission cylinder 39, the connecting case 36, and the transmission gear case 35, and the socket 26c of the right headlamp 26 is lateral. The transmission cylinder 31 and the support frame 37 are disposed so as to avoid the sides. In addition, the work lamps 23 and 27 are arranged behind the headlamps 22 and 26.

  Combined with such a configuration, the headlamps 22 and 26 and the work lamps 23 and 27 are disposed above the pulling device 12,. Therefore, the protrusion of the light units 20 and 21 forward and upward can be reduced, and the visibility of the divider can be improved.

  Further, while the headlamps 22 and 26 and the work lamps 23 and 27 are arranged in a limited space, the area of the reflector of the headlamps 22 and 26 is larger than the area of the reflector of the work lamps 23 and 27. Since it is set, it is possible to irradiate light well in accordance with the irradiation range.

  Note that the headlamp and the work lamp may both be disposed outside the machine body in the left-right direction with respect to the outermost raising device.

  Further, the area of the reflector of the headlamp or work lamp may be either a projected area or a surface area in front view.

  Further, in this embodiment, the shape of the concave portion of the side cover is formed in a substantially half-moon shape, but if the straight line connecting the work lamp and the divider is not obstructed by the side cover, the shape of the concave portion is It may be formed.
