Power is transmitted from the discharge conveyor to the grain discharge device 15, so that the discharge provided in the grain discharge device 15 is transmitted. The grain in the Glen tank 13 can be discharged from the outlet 19 to the outside.

  The grain discharging device 15 is mainly composed of a vertical discharging auger 17 that vertically communicates grains with a lower end communicating with a discharging conveyor, and a horizontal discharging auger that communicates with the upper ends of the vertical discharging auger 17 and laterally feeds the grains. 30. A base end side of the horizontal discharge auger 30 is pivotally attached to an upper end of a vertical discharge auger 17 standing on the rear side of the Glen tank 13 so as to be vertically rotatable.

A proximal-side auger lid 51 and a distal-side auger lid 52 are provided at the distal-side end and the proximal-side end of the distal-side auger 32, respectively.

  Thereby, the fall of residues, such as a grain by the vibration at the time of cutting work and a movement at the time of auger accommodation, can be prevented. Further, when the proximal end auger lid 51 is closed, even if the distal end auger 32 is to be connected, the proximal auger lid 51 comes into contact with the transport conveyor shaft 46 of the distal end side auger 32. It is possible to prevent clogging and the like. Furthermore, it is possible to prevent insects and the like from entering the proximal end side auger 31 and the distal end side auger 32 during storage.

  Further, an opening for inserting the transport conveyor shaft 46 protruding from the distal end side auger 32 or the proximal end auger 31 is provided in the central portion of the distal end side auger lid 52 or the proximal end side auger lid 51. A regulating member is provided outside the lid of the proximal end auger 31.

  In the present embodiment, the base end side auger lid 51 and the distal end side auger lid 52 are pivotally supported on the upper portions of the flange 34 and the flange 35 via pivot members, respectively, as in the above embodiment. Coil springs 71 and 71 are inserted in the pivotal support portion, and the proximal end auger lid 51 and the distal end side auger lid 52 are urged upward (in the opening direction) by the coil springs 71 and 71. That is, when the stoppers 57 and 58 serving as the fixing portions are released, the proximal end auger lid 51 and the distal end auger lid 52 are opened by the biasing force of the coil springs 71 and 71.

Here, a sliding rod 62 is disposed on the side surface of the base end side auger 31 through a sliding rod case 61 so as to be slidable back and forth. The front end of the sliding rod 62 is in contact with the proximal-side auger lid 51 and the rear end is pivotally supported by the link 64 so as to be capable of mutual rotation. The link 64 is connected to a lock lever 65 pivotally supported by the lock lever stay 63 so as not to be rotatable relative to the lock lever stay 63, and is configured to be rotatable forward and backward by the rotation of the lock lever 65. The lock lever stay 63 is disposed on the side surface of the proximal end auger 31.

The link 67 is pivotally supported by the link stay 66 and is configured to be rotatable by the rotation of the lock lever 65. The link stay 66 is disposed on the side surface of the distal end side auger 32.
Further, a lock pin 70 projects from the link stay 66 so that a hook portion formed at the tip of the lock lever 65 can be engaged.

  In the above configuration, when the operator rotates the lock lever 65 in the unlocking direction indicated by the arrow A in FIG. 9, the link 64 rotates in the direction indicated by the arrow B, and the sliding rod 62 is moved forward. Slide. Then, the sliding rod 62 pivots the proximal end side auger lid 51 forward to release the stopper 57, and the proximal end side auger lid 51 is opened by the biasing force of the coil spring 71. Further, the link 67 rotates in the directions of the arrow D and the arrow E with the rotation of the lock lever 65, and the sliding rod 69 is slid forward. Then, the sliding rod 69 rotates the tip side auger lid 52 forward to release the stopper 58, and the tip side auger lid 52 is opened by the biasing force of the coil spring 71. Thus, in this embodiment, both the base end side auger lid 51 and the distal end side auger lid 52 are configured to be opened with one touch by rotating the lock lever 65.

  On the other hand, by the biasing force of the coil springs 71 and 71, the proximal end auger lid 51 and the distal end auger lid 52 are biased so as to be closed, and the fixtures 55 and 56 which are the fixing portions at the opened positions are used. The sliding rods 62 and 69 are slidably arranged in the vertical direction, the lock lever 65 is pivotally supported by a pivot shaft in the front-rear direction, and a contact body protruding from the lock lever 65 is provided. The sliding rods 62 and 69 are disposed so as to be able to come into contact therewith. In this manner, the proximal end side auger lid 51 and the distal end side auger lid 52 can be automatically closed by pushing the sliding rods 62 and 69 by the rotation operation of the lock lever 65 in the locking direction. Further, the sliding rods 62 and 69 may be connected to arms fixed to the rotation shafts of the proximal auger lid 51 and the distal auger lid 52, and the sliding rods may be slid by an actuator. Is possible.

  Thus, one end of the distal end side auger lid 52 or the proximal end side auger lid 51 is pivotally supported on one side of the distal end side end portion of the proximal end side auger 31 and the proximal end side end portion of the distal end side auger 32, respectively. In addition, a fixing portion is formed on the other side, and a spring that biases the lid 51 or 52 in a closing direction or an opening direction is disposed on the pivot portion. Thereby, it can be easily closed or opened by releasing the fixing of the lids 51 and 52.

As shown by a two-dot chain line in FIG. 3, the horizontal discharge auger 30 is in a state of being placed on the second auger rest 26b. When the horizontal discharge auger 30 is placed and stored in the lower storage position, the distal auger 32 of the horizontal discharge auger 30 can be rotated to store the horizontal discharge auger 30 with a reduced width.

  Specifically, as shown in FIG. 3, the lateral discharge auger 30 can be lowered by a height H in FIG. 3 by moving from the first auger rest 26a to the second auger rest 26b. On the other hand, as shown in FIG. 2, when the horizontal discharge auger 30 is moved to the lower storage position, it is widened by the length of L in FIG. 2, but when the horizontal discharge auger 30 is folded as described above, The horizontal discharge auger 30 can be stored in the lower storage position without increasing the overall width of the machine body.

  In this way, the second augerest 26b is provided at a lower position outside the body than the first augerest 26a. Thereby, it is possible to change from the upper storage position to the lower storage position only by moving the lateral discharge auger 30 from the first auger rest 26a to the second auger rest 26b. Further, since the distal discharge auger 32 can be bent by turning the distal end auger 32, the distal end of the horizontal discharge auger 30 does not protrude from the end surface of the machine body, and the horizontal discharge auger 30 is not changed without changing the entire width of the machine body. 30 can be stored in the lower position.
