  However, as described in Patent Document 1, in the conventional combine, the two left and right entrance / exit grips are provided only at a high position of the entrance / exit, so that the entrance / exit step is performed while grasping the entrance / exit grip. In addition, because of the vertical climbing posture, there has been a problem that it is difficult to ensure good boarding / exiting performance for a combine that has been increasing in size in recent years.

The present invention was created for the purpose of solving these problems in view of the above circumstances, and in a combine provided with a boarding / unloading grip that is gripped at the time of boarding / alighting on the side of a boarding / alighting step having a boarding / alighting step. The above-mentioned getting on / off grips are provided in three places, the installation height of each getting-on / off grip is set in stages, and the uppermost and lowermost getting-on / off grips are arranged on one side of the getting-on / off entrance, and the middle getting-on / off grips are got on / off It is arranged on the other side of the mouth. In this way, the operator can climb the boarding step while grasping the boarding grip at the higher position in order from the boarding grip at the lower position. In particular, it is possible to greatly improve the ease of getting on and off of a relatively small operator.
In addition, a driving grip that is gripped during driving is provided above the front panel that stands in front of the driver's seat, and a leg portion that supports one end of the driving grip is extended along the outer side of the front panel, so that It is characterized by a boarding / exit grip. If it does in this way, since the lowest boarding grip can be added only by extending the leg part of a driving grip, the increase in a number of parts can be avoided and the rise in cost can be controlled.

  Next, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a combine, and the combine 1 was selected by a pre-processing unit 2 that cuts the stems and a threshing unit (not shown) that threshs and sorts the grains from the cut stems. A grain tank 4 for storing the grain, a discharge auger 5 for discharging and conveying the grain in the grain tank 4 to the outside of the machine, a post-processing unit 6 for post-processing the threshed waste, and an operator board the vehicle. The driving unit 7 and a crawler type traveling unit S are provided.

  As shown in FIGS. 2-6, the operation part 7 is provided in the right offset position of the front part of an airframe, and an operator gets on / off via the entrance 8 formed in a right side part.

There are provided a mowing / working machine clutch switch 15, various automatic control ON / OFF operations and various automatic switch groups 16 for setting, and the front panel 10 is erected in front of the driver's seat 9, A multi-steering lever 17 that can be tilted in the direction and the front-rear direction is provided. This multi-steering lever 17 serves as both a body turning operation tool (left-right direction operation) and a pre-processing lifting operation tool (front-rear direction operation). Normally, an operator always holds the multi-steering lever 17 with the right hand while traveling. ing.

  The front panel 10 is provided with an armrest 18 and a driving grip 19 to reduce operator fatigue. The armrest 18 is disposed on the front side of the multi-steering lever 17 when viewed from the driver's seat 9 side so as to support the wrist or arm of the hand that grips the grip 17a of the multi-steering lever 17. The driving grip 19 is a pipe-shaped grip that is gripped during driving or the like. In the present embodiment, the driving grip 19 is formed in an L shape so as to surround the entire front panel 10 and the front half of the side panel 11 in plan view. ing. The driving grip 19 is disposed above the front panel 10 and the side panel 11 at a predetermined interval, and is extended to the front panel 10 and the side via legs 19a and 19b extending downward from both ends. The panel 11 is fixed.

  The entrance / exit 8 is formed between the right end portion of the front panel 10 and the right end portion of the engine cover 20 (air cleaner cover 21), and the entrance / exit step 24 provided in a stepped manner on the falling surface 23 of the operation step 22. , 25 is used to get on and off. In the present embodiment, since the two steps of getting on / off steps 24 and 25 are configured, the first boarding operation (see FIG. 7) that rises from the ground to the lower step of getting on / off step 25 and the lower step of getting on / off step 25 are performed. The second boarding operation (see FIG. 8) rising from the upper boarding step 24 to the upper boarding step 24 (see FIG. 8) and the third boarding operation (see FIG. 9) going up from the upper boarding step 24 to the driving step 22 are performed in three stages.

  In this type of combine 1, a boarding grip is usually provided on the left and right sides of the boarding gate 8, and the operator goes up and down in the boarding steps 24 and 25 while holding the boarding grip. Conventionally, since two entrance grips on the left and right sides are provided only at a high position of the entrance 8, the entrance / exit posture that climbs vertically when the entrance / exit steps 24 and 25 are performed while holding the entrance / exit grip. Therefore, there has been a problem that it is difficult to secure good boarding / exiting performance in a combine that has been increasing in size in recent years. The combine 1 which concerns on embodiment of this invention has a means for solving such a subject, and demonstrates a solving means concretely below.

  As shown in FIGS. 7 to 9, in the combine 1 according to the embodiment of the present invention, the entrance / exit grips 26 to 28 that are gripped at the time of getting on and off are provided at three places on the side of the entrance 8 having the entrance and exit steps 24 and 25. The installation height of each of the entrance / exit grips 26 to 28 is set stepwise, the uppermost and lowermost entrance / exit grips 26, 28 are arranged on the right side of the entrance / exit 8, and the middle entrance / exit grip 27 is placed on the entrance / exit 8. Located on the left side. In this way, the operator can ascend the getting-on / off steps 24, 25 while grasping the getting-on / off grips 27, 28 in order from the getting-on / off grip 26 at the lower position, so that the operator does not take the getting-on / off posture like climbing vertically. Thus, it is possible to easily get on the driving unit 7, and in particular, it is possible to greatly improve the boarding / exiting performance of a relatively small operator.

  In other words, taking the case of boarding as an example, as shown in FIGS. 7 to 9, the first boarding operation that rises from the ground to the lower boarding step 25 can be performed while grasping the lower boarding grip 28 with the right hand. (See FIG. 7) Further, the second riding operation that rises from the lower boarding step 25 to the upper boarding step 24 is performed while holding the lower boarding grip 28 with the right hand and the middle boarding grip 27 with the left hand. In addition, the third riding operation that rises from the upper boarding / unloading step 24 to the driving step 22 is performed while holding the middle boarding / grip grip 27 with the left hand and the top boarding / grip grip 26 with the right hand. (See FIG. 9). Hereinafter, the specific structure of each boarding grip 26-28 which concerns on this embodiment is demonstrated.

  The uppermost entrance / exit grip 26 is configured using the armrest 18. Specifically, the leg portion 18 a that supports the right end portion of the armrest 18 is arranged at the uppermost stage on the right side of the entrance 8 and serves as the uppermost boarding grip 28. In this way, the uppermost entry / exit grip 28 can be configured without adding parts, so that an increase in the number of parts can be avoided and an increase in cost can be suppressed. The middle boarding / alighting grip 27 is attached to the upper end of the engine cover 20 and the front end of the cleaner cover 21, and the shape thereof is the same as that shown in Patent Document 1.

  The lowermost boarding / alighting grip 28 is configured using the driving grip 19. Specifically, the leg portion 19b that supports the right end (one end) of the driving grip 19 is extended along the right side (outer side) of the front panel 10 to form a lowermost boarding grip 28. In this way, since the lowermost boarding / alighting grip 28 can be added by simply extending the leg 19b of the driving grip 19, an increase in the number of parts can be avoided and an increase in cost can be suppressed.

  Reference numeral 29 denotes a support stay for fixing the leg portion 19b of the driving grip 19 to the right side surface portion of the front panel 10, and extends the leg portion 19b downward beyond the support stay 29, and the lower end of the extension portion. The lower portion of the getting-on / off grip 28 is configured by bending the portion inwardly and inserting the tip portion into an insertion hole 10 a formed on the side surface of the front panel 10. In addition, the support stay 29 is also used as a support portion of the mirror 30, so that an inexpensive mirror can be attached.

  According to the present embodiment configured as described, in the combine 1 in which the entrance / exit grips 26 to 28 that are gripped at the time of getting on / off are provided on the side of the entrance 8 having the entrance / exit steps 24 and 25, the entrance / exit grips 26 to 28 are provided. Provided at three locations, the installation height of each of the entrance / exit grips 26 to 28 is set in stages, and the uppermost and lowermost entrance / exit grips 26, 28 are arranged on the right side of the entrance / exit 8, and the intermediate entrance / exit grip 27 Is placed on the left side of the entrance 8 so that the operator can ascend the entrance / exit steps 24 and 25 while grasping the entrance / exit grips 26 and 27 at the higher position in order from the entrance / exit grip 28 at the lower position. It is possible to easily get on the driving unit 7 without taking a climbing posture such as climbing, and in particular, it is possible to greatly improve the getting on and off of a relatively small operator.

  Further, a driving grip 19 that is gripped during driving is provided above the front panel 10 erected in front of the driver's seat 9, and a leg portion 19 b that supports one end of the driving grip 19 extends along the outer side of the front panel 10. By extending the lowermost grip 28, it is possible to avoid an increase in the number of parts and to suppress an increase in cost.
