A pre-processing unit 9 provided at the rear end with a handling depth transport body 8 for lifting and transporting the harvested culm to the feed chain 7 so that the harvested culm can be passed on to the feed chain 7 is attached to be able to vertically move and swing. At this time, the front end of the threshing unit 4 is located behind the front end of the driver's seat 6, and the handling depth transport body 8 is located on the left side (inside) of the driver's seat 6 in front of the threshing unit 4. ing. The space on the left side of the driver's seat 6 where the handling depth conveying body 8 and the like are located is referred to as a preprocessing unit side space 16. The harvested grain culm is passed from the handling depth conveying body 8 to the feed chain 7 in the pre-processing unit side space 16 and sent to the threshing unit 4 by the feed chain 7.
[0007]
On the other hand, the driver's seat 67 has a seat 11 and a front operation unit 12 and a side operation unit 13 for controlling a combine in front and on the left side. On the left side of the side operation unit 13, a pre-processing shift lever 14 for shifting the speed of the pre-processing unit 9 is provided so as to protrude from a guide frame 15 on the machine body 1 side that protrudes toward the pre-processing unit side space 16. I have. Further, an engine (not shown) is provided below the driver's seat 6, and an engine cover 10 provided with an intake port on the right side of the engine and the seat 11 is provided with an intake port for taking in air to the engine side in front and side. Covered with.
[0008]
A Glen tank 17 for temporarily storing the grains threshed by the threshing unit 4 is provided behind the driver's seat 6 and on the right side of the threshing unit 4, and a Glen tank 17 is provided behind the Glen tank 17. A grain discharge cylinder 18 for discharging the grains inside the body 17 to the outside of the machine body 1 is provided. The grain discharge cylinder 18 has a shape in which a vertical pipe 18a and a horizontal pipe 18b are substantially L-shaped, and the horizontal pipe 18b determines a horizontal rotation centered on the vertical pipe 18a and a connection point between the vertical pipe 18a and the vertical pipe 18a. Up and down swing as a fulcrum is possible.
[0009]
Except for discharging the grains in the Glen tank 17, the grain discharge cylinder 18 is arranged in the front-rear direction so that the horizontal pipe 18 b is substantially parallel to the machine body frame 2 and the end reaches above the pre-processing unit 9. It is stored above the driver's seat 6 while protruding forward (forward). At this time (at the time of storage), the horizontal pipe 18b passes through the left side of the driver's seat 6 and is inclined in a plan view (FIG. 2A). Further, a shielding sheet 19 described later is attached to the horizontal pipe 18b of the grain discharge cylinder 18 along the horizontal pipe 18b.
[0010]
Next, the structure of the shielding sheet 19 will be described with reference to the perspective view of FIG. The closing sheet 19 includes a U-shaped frame 21 having a storage space 21 a, a roller bar 23 having a spring 22 inside rotatably supported at both ends by the frame 21, and a roller bar 23. A sheet member 24 formed of a transparent member having one end attached to 23, an end rod 26 having a predetermined weight attached to the other end (free end) 24a of the sheet member 24, and the like. ing. The frame 21 is fixed to the horizontal pipe 18 b via an attachment member 20 such as a belt, so that the shielding sheet 19 is attached to the grain discharge cylinder 18.
[0011]
At this time, the shielding sheet 19 is attached to a portion of the horizontal pipe 18b opposite to the front position of the threshing unit cover 3 on the left side of the driver's seat 6 so that a later-described feeding operation can be performed downward. On the other hand, as shown in FIG. 2B, a mounting portion 28 is provided on the end rod 26 so as to be detachable from a fixing portion 27 provided on the driver's seat 6 side of the guide frame 15 so as to protrude downward. Have been. Note that the fixing portion 27 and the mounting portion 28 may be of any type as long as they can be easily attached and detached, such as a pair of detachable tapes.
[0012]
The roller bar 23 can rotate so as to wind the free end 24a side of the sheet member 24 toward the roller bar 23 (the end where the sheet member 24 is attached to the roller bar 23) by the urging force of the spring 22. As described above, the free end 24a of the sheet member 24 wound up and stored in the storage space 21a with the free end 24a wound up toward the mounting end side can be fed out against the urging force. The shielding sheet 19 has the same structure as a so-called roll screen, and the amount of feeding of the free end 24a (the sheet member 24) can be arbitrarily adjusted.
[0013]
That is, when the operator pulls out the free end 24a with the mounting portion 28 or the like and stops the drawing at an arbitrary position, the free end 24a stops at that position, and after the stopped free end 24a is slightly drawn out, the free end 24a Is released, the sheet member 24 is wound up and stored by the biasing force of the spring 22 as described above. With the above structure, the seat member 24 is extended by a necessary amount and the mounting portion 28 is fixed to the fixing portion 27. As shown in FIGS. 1 to 3, the driver's seat 6 and the above-mentioned preprocessing section side space 16 are separated from each other. It is shut off by. At this time, the end rod 26 functions as a weight. It should be noted that the shielding between the driver's seat 6 and the preprocessing section side space 16 by the sheet member 24 can be performed only when the grain discharge cylinder 18 is in the housed state.
[0014]
On the other hand, in the combine, during the operation of the engine, the air for cooling the engine enters the engine side through the intake port of the engine cover 10 to cool the engine. For this reason, the air for cooling the engine is heated by the heat of the engine to become hot air, and this hot air leaks into the pretreatment section side space 16. During the combine operation, the harvested grain culm is transferred from the preprocessing section 9 to the threshing section 4 from the preprocessing section 9 in the form in which the harvested grain culm is passed from the handling depth transfer body 8 to the feed chain 7 in the preprocessing section side space 16 as described above. As a result, dust is also generated in the pretreatment unit side space 16 due to the harvested and harvested culm.
[0015]
On the other hand, when the driver's seat 6 side and the pre-processing unit side space 16 side are closed and closed by the sheet member 24 as described above, the hot air, dust, and the like accumulated in the pre-processing unit side space 16 as described above are discharged. The driver's seat 6 is kept from entering the driver's seat 6 side without being hindered by the 24. Further, at this time, the grain discharge cylinder 18 (lateral pipe 18b) passes through the left side from the driver's seat as described above and is stored in an inclined manner in plan view as shown in FIG. The end (roller bar 23) side is vertically inclined in a direction away from the driver's seat 6 to the left, the mounting end side of the seat member 24 expands forward, and the free end 24a side is on the side of the driver's seat 6. The driver's seat 6 side and the preprocessing unit side space 16 side are closed in a curved state along the side.
[0016]
Accordingly, the seat member 24 functions to guide and discharge the hot air, dust, and the like to the left side of the body 1, and more effectively guards the driver's seat 6 from the hot air, dust, and the like. Further, the closed state between the driver's seat 6 side of the seat member 24 and the preprocessing unit side space 16 side is such that the mounting end side of the seat member 24 is widened forward in the left-right direction as described above, Since the free end 24a is curved along the side of the driver's seat 6, the living space of the driver's seat 6 is relatively large, and the livability in the driver's seat 6 and the front operation part 12 and the side operation part 13 The operability is good and the front view is also good.
[0017]
In a state where the driver's seat 6 and the pre-processing unit side space 16 are closed by the seat member 24, the pre-processing speed change lever 14 is located on the pre-processing unit side space 16 side. However, by detaching the mounting portion 28 from the fixing portion 27 and winding and storing the sheet member 24 in the storage space 21a as described above, the above-mentioned closing is easily released and the pre-processing shift lever 14 is easily operated. can do. At this time, since the free end 24a side of the sheet member 24 is wound around the mounting end side, the sheet member 24 does not hinder the operation of the pre-processing shift lever 14. In addition, since the sheet member 24 is formed of a transparent member, the pre-processing shift lever 14 and the like can be checked silently even during the closing operation, so that an operation error is not missed.
[0018]
Next, a case where the above-mentioned shielding sheet 19 is attached to the front end portion of the threshing unit cover 3 will be described. As shown in FIG. 5, the frame 21 is fixed in the left-right direction above the front end of the threshing unit cover 3 so that the shielding sheet 19 can be fed forward, and for example, A fixing unit 31 similar to the fixing unit 27 is provided on the preprocessing unit 9 side. In this embodiment, the sheet member 24 is fed out and the mounting portion 28 is fixed to the fixing portion 31 in the same manner as in the above-described embodiment, so that the upper part of the pretreatment portion side space 16 is approximately at the height of the threshing portion cover 3. The driver's seat 6 side and the preprocessing unit side space 16 can be closed and closed like a lid.
[0019]
Thus, similarly to the above-described embodiment, the hot air, dust, and the like in the space 16 are not blocked by the seat member and do not enter the driver's seat 6 side, and the environment in the driver's seat 6 is maintained. At this time, since the sheet member 24 is transparent, it is possible to silently check the working state of the transport of the harvested grain culm at the handling depth, the transfer to the feed chain 7, and the like, without missing any trouble in the process.
[0020]
【The invention's effect】
According to the present invention configured as described above, the closing sheet shields the driver's seat side and the space on the preprocessing unit side located inside the driver's seat, so that the space on the preprocessing unit side There is an effect that the environment inside the driver's seat is maintained because hot air from the engine and dust and the like generated by the harvested stalks are not hindered by the seat and enter the driver's seat side. If necessary, the lower end or the front end, which is the attaching / detaching side of the sheet member, can be removed from the fixing portion of the machine body or the threshing unit cover to operate the threshing unit or the preprocessing unit.
[0021]
In particular, the detachable side of the shielding sheet has a structure capable of being retracted and retracted with respect to the mounting side, and the sheet member removed from the fixed portion for the purpose of performing operations on the threshing unit or the preprocessing unit side. The detachable end is compactly stored on the mounting end side, so that the closing sheet does not hinder the above-mentioned operations.
[0022]
Further, when the seat member is formed of a transparent member, there is also an effect that the above-mentioned operation portion and the like can be visually checked from the driver's seat through the transparent sheet member.
