By expanding the discharge port, it is possible to discharge the waste straw cut evenly and uniformly in the field.

  1 to 3 are a side view, a plan view, and a rear view of the combine of the present invention. A body frame 2 is supported on the left and right crawler type traveling devices 1. A driver's seat 3 is provided on the right side of the vehicle body frame 2. A pre-processing unit 4 is provided in front of the driver's seat 3 so as to be movable up and down on the body frame 2 side. The pre-processing unit 4 cuts the grain culm in the field and conveys it backward.

  On the left side of the driver's seat 3, there is provided a handling depth transport body that adjusts the handling depth of the cereal that has been cut by the preprocessing unit 4 and transports it to the rear. A threshing device 6 for threshing cereals conveyed by the handling depth carrier is mounted on the machine body frame 2 behind the handling depth carrier.

  Behind the threshing device 6 is mounted a cutter 7 for cutting the waste after threshing. On the side of the threshing device 6 and the cutter 7, there is provided a Glen tank 8 that is located behind the driver's seat 3 and temporarily stores the threshed grain. A discharge auger device 9 that discharges grains from the grain tank 8 is provided behind the grain tank 8.

  The fuselage 11 of this combine is comprised as mentioned above. This combine harvests the cereals by the pre-processing unit 4 by traveling on the field, and transports the harvested cereals to the threshing device 6 while adjusting the handling depth by the handling depth transporter. The threshed grains are stored in the glen tank 8 and the waste after threshing is cut by the cutter 7 and discharged to the field. The grain in the Glen tank 8 is discharged out of the machine by a discharge auger device 9 as necessary.

  This combine is a combine for cutting 4 lines. The width of the cutter 7 is smaller than the cutting width by the preprocessing unit 4. Therefore, when the waste is cut by the cutter 7 and the cut waste is dropped directly below the cutter 7 and discharged outside the machine, the difference waste between the cutting width and the width of the cutter 7 is not discharged to the field ( A line that does not fall) is created.

  In order to avoid this, a diffusion spiral (not shown) is provided in the cutter 7. Further, an openable / closable discharge cover 12 is provided on the right side to expand the discharge port of the cutter 7 in the width direction. By opening the discharge cover 12 outward (on the right side), it becomes possible to discharge the waste to a range that is equal to or larger than the width of the cutter 7, and it is possible to eliminate the above-mentioned line where the waste does not fall. Since the discharge cover 12 is openable, it can be closed.

  On the side of the cutter 7, a longitudinal cutter column 13 for supporting the cutter 7 is provided at a position in front of the discharge cover 12. The cutter column 13 is erected from the body frame 2. An arm 14 protrudes rearward from the cutter column 13. The arm 14 is fixed to the cutter column 13. The arms 14 are provided on the upper and lower sides, respectively. Both cutter arms 14 are positioned above the discharge cover 12. The cutter arm 14 does not prevent the discharge cover 12 from being opened and closed.

  A cutter fulcrum shaft 16 protrudes upward from the tip of the arm 14. The cutter 7 is rotatably attached to the cutter fulcrum shaft 16 at the rear end portion on the right side. The cutter 7 can be opened and closed with the cutter fulcrum shaft 16 disposed at the rear end position on the right side of the cutter 7 as a rotation fulcrum.

  The discharge auger device 9 includes a vertical spiral cylinder 17 in the vertical direction in which a vertical spiral is accommodated, and a horizontal spiral cylinder 18 in the front-rear direction in which the horizontal spiral is accommodated. The vertical spiral cylinder 17 is located behind the grain tank 8 and substantially next to the cutter 7 so that the vertical spiral can inherit the grain from the spiral for discharging and feeding the grain provided in the grain tank 8. Has been placed.

  A lower end portion of the vertical spiral cylinder 17 is rotatably attached to a connecting cylinder 19 having a substantially L shape in a side view in which grains are transferred from the helix to the vertical helix on the grain tank 7 side. Between the vertical spiral cylinder 17 and the connecting cylinder 19, a rotation driving mechanism for the vertical spiral cylinder 17 by the auger motor 21 is provided.

  The vertical spiral cylinder 17 can be rotated around the axis center with respect to the body frame 2 by a rotation drive mechanism (auger motor 21). The auger motor 21 is disposed substantially directly behind the vertical spiral cylinder 17. The Glen tank 8 is openable and closable about the vertical spiral cylinder 17.

  The horizontal spiral cylinder 18 is attached to the upper end portion of the vertical spiral cylinder 17 so as to be swingable up and down. The horizontal spiral cylinder 18 pivots in the horizontal direction by the rotation of the vertical spiral cylinder and swings up and down with respect to the vertical spiral cylinder 17. A grain discharge portion 22 is provided at the tip of the horizontal spiral cylinder 18. The horizontal helix rotates in synchronization with the vertical helix, inherits the grain conveyed to the upper end of the vertical helix, conveys the inherited grain toward the tip of the horizontal helix 18, and discharges it from the discharge unit 22.

  As described above, in the discharge auger device 9, the vertical spiral cylinder 17 conveys the grains in the grain tank 7 in the vertical direction as described above, and the horizontal spiral cylinder 18 inherits the grains from the vertical spiral cylinder 17 and discharges them. It is structured to discharge from the part 22. The position of the discharging part 22 (the discharging position of the grain) can be arbitrarily adjusted by turning and swinging the horizontal spiral cylinder 18.

  However, the discharge spiral device 9 is stored in a storage state in which the horizontal spiral tube 18 is inclined in a plan view and substantially horizontal in a side view so that the horizontal spiral cylinder 18 is directed to the left front of the body 11 when the grain is not discharged. .

  A vertical auger column 23 for supporting the discharge auger device 9 is provided substantially parallel to the right side (substantially right side) of the cutter column 13. The auger column 23 is disposed substantially beside the vertical spiral cylinder 17 and is erected from the machine body frame 2. A bracket 24 is provided on the upper portion of the auger column 23. The upper portion of the vertical spiral cylinder 17 is supported by the bracket 24 in a state where rotation is permitted.

  In the discharge spiral device 9, the lower end of the vertical spiral cylinder 17 is supported by the connecting cylinder 19, and the upper portion is supported by the auger column 23 via the bracket 24. Supported in a stable state in space. The upper end of the auger column 23 and the upper end of the cutter column 13 are connected and fixed by a plate 26.

  A space surrounded by the auger column 23, the cutter column 13 and the plate 26 is closed by the plate 25. The plate 25 is welded to the auger column 23, the cutter column 13, and the plate 26. The auger column 23 and the cutter column 13 are configured as an integral frame, and the strength is improved, so that the discharge spiral device 9 (vertical spiral cylinder 17) and the cutter 7 can be supported stably and firmly.

  The vertical spiral cylinder 17 is provided as close to the rear and right side as possible within a range in which the discharge auger device 9 does not protrude from the body width in the stored state. Thereby, the open / close space of the discharge cover 12 can be secured between the side surface of the cutter 7 and the vertical spiral cylinder 17. The discharge cover 12 can be easily opened and closed without being obstructed by the vertical spiral cylinder 17, and it is not necessary to reduce the opening and closing angle of the discharge cover 12, and a sufficient discharge range of the straw can be secured.

  Compared to the combine in which the vertical spiral cylinder 17 is arranged on the side of the threshing device 6 as in the prior art, since the vertical spiral cylinder 17 is provided to move backward, the Glen tank 8 is the front end face of the cutter 7. It is enlarged toward the back to the vicinity position. Thereby, the capacity | capacitance of the grain tank 8 is expanded, without making the height of the grain tank 8 high. That is, it is not necessary to increase the glen tank 8 in order to increase the capacity of the glen tank 8, and deterioration of the rear field of view due to an increase in the glen tank 8 height is prevented.

  The vertical spiral cylinder 17 is surrounded and protected by a cover 27 that is substantially L-shaped in plan view so as to connect the right end of the back surface of the cutter 7 and the rear end of the side surface of the glen tank 8. However, the upper part of the vertical spiral cylinder 17 protrudes above the cover 27. The rotation mechanism including the auger motor 21, the hydraulic piping, the cutter support 13, and the auger support 23 are also located in the cover 21 and are protected by the cover 27.

  As a result, the vertical spiral cylinder 17 is located rearward compared to the conventional combine. However, the peripheral parts (rotation mechanism, hydraulic piping, etc.) provided on the vertical spiral cylinder 17 and the vertical spiral cylinder 17 side, the cutter column 13, Damage to the auger column 23 and the like is prevented by the cover 27. The cover 27 is pivotally supported by a lower fixed cover 28 fixed to the back surface of the cutter 7 and the side surface of the grain tank 8 and a pivot shaft 29 on the side surface side of the grain tank 8. And a rotating cover 31.

  The rotation cover 31 is openable and closable. By opening the fixed cover 31, at least the upper part of the auger motor 21 is bare and maintenance of the auger motor and the like can be easily performed.

  The fixed cover 28 and the rotating cover 31 are continuous with the back surface of the cutter 7 and the side surface of the grain tank 8 without any substantial difference, and the appearance of the combine is improved. That is, the cutter fulcrum shaft 16 allows the fixed cover 28 and the rotary cover 31 to be brought into contact with the back surface of the cutter 7 without the cutter 7 and the cover 27 (the fixed cover 28 and the rotary cover 31) coming into contact with each other when the cutter 7 is opened and closed. And it arrange | positions in the rear-end vicinity of the cutter 7 so that it can provide continuously with the side surface of the Glen tank 8, and substantially no level | step difference.
