  Next, the structure of the dust exhaust part 17 which is the principal part of this invention is demonstrated with reference to FIGS.

  In the present embodiment, the discharge port 11 formed at the rear portion of the handling chamber 7 is disposed behind the rear end of the swinging sorter 12, and the discharge discharged from the discharge port 11 of the handling chamber 7 is When discharging from the lower dust outlet 21 to the outside of the machine without returning to the swinging sorter 12, the dust outlet 17 has an inclined posture (front height rear) A low-inclined sink plate 22, a rubber plate 23 that extends at the rear end of the swing sorter 12 and closes the gap between the swing sorter 12 and the sink plate 22, and mainly swings. A dust cover 24 is provided for guiding the discharge discharged from the sorting body 12 side to the dust outlet 21.

  In such a dust discharge unit 17, there is a possibility that the discharge discharged from the dust discharge port 21 interferes with the uncut stem culm and hinders the cutting of the uncut stem culm. In particular, when harvesting crops with a large amount of waste or crops that easily collect waste, the waste has a high possibility of hindering the cutting of uncut stems. In addition, as shown in FIG. 3, when the left side is an uncut area (a region beyond the leftmost divider 25) and the rotation direction of the handling cylinder 9 is a clockwise direction in the rear view, The discharge was easy to be discharged to the uncut area.

  Therefore, in the general-purpose combine 1 according to the embodiment of the present invention, the above-described problem is solved by providing a moving means for moving the discharged material to the already-cut-ground side behind the swinging sorter 12. Specifically, a plurality of guide plates 27 are projected in parallel on the flow surface 22a of the flow plate 22, and the guide plates 27 are inclined so as to approach the already-cut area toward the lower side. In this way, the discharge on the sink plate 22 can be guided to the already cut ground side by the guide plate 27. Moreover, since the guide plates 27 projecting in parallel with a predetermined interval have an action to disperse the discharged matter, even the discharged matter that tends to clump can be brought close to the already-cutted area.

  Further, a rubber plate sliding contact surface 22b that is in sliding contact with the rubber plate 23 is provided at the front end portion of the flow plate 22, and the flow surface 22a is provided between the rubber plate sliding contact surface 22b and the flow surface 22a. A step 22c is provided for lowering the rubber plate sliding contact surface 22b. In this way, the discharge from the handling chamber 7 can be dispersed by the plurality of guide plates 27 while dropping from the rubber plate 23 onto the flow surface 22a of the flow plate 22 through the step 22c. Even if the discharge is easy to collect, it is possible to reliably bring it to the already-cut area.

  The sink plate 22 of the present embodiment is integrally provided with a sink surface 22a, a rubber plate sliding contact surface 22b, a step 22c, and a guide plate 27, and is detachably attached to the threshing portion 3. Specifically, as shown in FIG. 5, the left and right end portions of the sink plate 22 are bolted to the left and right side plates 29 of the threshing portion 3 via L-shaped attachment plates 28, respectively. In this way, by removing the sink plate 22, the rear of the swinging sorter 12 can be widely opened, so that the maintenance of the swinging sorter 12 and the like is facilitated. Although the left L-shaped mounting plate 28 is welded to the sink plate 22, the right L-shaped mounting plate 28 is welded to the right side plate 29 of the threshing portion 3, so that the right end portion of the sink plate 22 is welded. A mounting hole 22d through which a bolt is passed is formed.

  In the present embodiment, the flow surface 22a of the flow plate 22 and the surface of the guide plate 27 are covered with a water repellent material (for example, fluorine-containing paint). In this way, when harvesting a crop with a lot of water, the slipping of the discharge in the sink plate 22 and the guide plate 27 can be promoted by the water repellent material, so that the stagnation and clogging of the discharge in the dust discharge portion 17 are prevented. Can be prevented.

  In this embodiment, the rubber plate slidable contact surface 22 b is substantially the same height as the upper end of the guide plate 27, but the rubber plate slidable contact surface 22 b may be higher than the upper end of the guide plate 27. In this way, it is possible to avoid such inconveniences that the rubber plate 23 interferes with the guide plate 27 and is damaged, or the discharged material is caught between the rubber plate 23 and the guide plate 27 and stagnated.

  In this embodiment, the guide plate 27 is fixedly attached integrally to the flow plate 22, but the guide plate 27 may be adjustable in angle as shown in FIG. For example, the upper end portion of the guide plate 27 is attached to the sink plate 22 via the hinge 30 so that the guide plate 27 can be turned left and right around the hinge 30 and the lower end portion of the guide plate 27 is moved to the sink plate. Bolts are attached to the sink plate 22 through arc-shaped long holes 22 e formed in the plate 22. If it does in this way, since the angle of the guide plate 27 can be adjusted arbitrarily, the angle of the guide plate 27 can be optimized according to the kind of crop, the amount of moisture, and the like.

  Next, the dust cover 24 of this embodiment will be described. As shown in FIG. 4, the dust cover 24 of the present embodiment is disposed behind the rocking sorter 12 in order to guide the waste discharged mainly from the rocking sorter 12 side to the dust outlet 21. In addition, a rear cover 31 having a U-shaped cross section that is disposed on the rear upper side of the sink plate 22 and is inclined in a front-rear and a rear-lower shape. A guide plate 32 is provided on the front surface of the rear cover 31 that guides the discharged material to the dust outlet 21 and guides the discharged material to the already cut ground. Thereby, the discharge | emission discharged | emitted from the rocking | swiveling sorter 12 side is also brought near to the uncut area side, and interference with an uncut stalk is avoided.

  The guide plate 32 may be fixedly attached integrally to the rear cover 31, but the guide plate 32 may be adjustable in angle as shown in FIG. For example, the upper end portion of the guide plate 32 is attached to the rear cover 31 via the hinge 33 to enable the guide plate 32 to turn left and right around the hinge 33, and the lower end portion of the guide plate 32 is connected to the rear cover. The rear cover 31 is bolted through an arc-shaped long hole 31 a formed in the base 31. If it does in this way, since the angle of the guide board 32 can be adjusted arbitrarily, the angle of the guide board 32 can be optimized according to the kind of crop, the amount of moisture, and the like.

  As shown in FIG. 4, the rear cover 31 can include an expansion cover 34 that expands the opening area of the dust exhaust port 21 as necessary. For example, the lower half of the rear cover 31 is notched, and the notched portion is covered with an extended cover 34 that can be retracted and rotated backward with the upper end hinge 35 as a fulcrum. In this way, when the discharge is clogged in the dust discharge portion 17, the extension cover 34 is retracted and rotated backward by the load of the clogged discharge, so that the dust discharge port 21 is expanded to facilitate discharge of the discharge. In addition, the dust cover 24 can be prevented from being damaged by the load of the clogged discharge.

  As shown in FIGS. 7 and 8, the dust cover 24 of the present embodiment is configured so that it can be stored compactly when not in operation, and can be easily attached and detached during maintenance of the threshing unit 3. More specifically, the dust cover 24 of the present embodiment is freely rotatable via left and right side plates 36 attached to the rear end surface portion of the threshing portion 3 and an upper rear end portion of the side plate 36 via a hinge 37. The above-described rear cover 31 to be connected is provided. A pair of front and rear screw holes 31b and 31c are formed in the left and right side portions of the rear cover 31, respectively, while one hole 36a is formed in each of the left and right side plates 36. Then, the front screw hole 31b is aligned with the hole 36a, and a bolt 38 with a knob is screwed into the screw hole 31b through the hole 36a, so that the rear cover 31 is fixed in the above-described front high rear low working posture. Is done. Also, the rear cover 31 is fixed in the stowed position by aligning the rear screw hole 31c with the hole 36a and screwing the knob bolt 38 into the screw hole 31c through the hole 36a. In this storage position, the rear cover 31 is stored in the left and right side plates 36, so that the length of the machine body when not working can be shortened as shown in FIG.

  Further, left and right pins 39 are integrally welded to the front lower ends of the left and right side plates 36, and holes 36b are formed in the front upper ends of the left and right side plates 36, respectively. Then, the left and right pins 39 are engaged with the left and right hooks 40 projecting from the rear end surface lower portion of the threshing portion 3, and the screw hole (not shown) formed in the upper portion of the rear end surface of the threshing portion 3 has a hole 36b. The dust cover 24 is detachably attached to the rear end portion of the threshing portion 3 by screwing the bolt 41 with the knob through the screw.

  In the present embodiment, the front surface of the rear cover 31 and the surface of the guide plate 32 are covered with a water repellent material (for example, fluorine-containing paint). In this way, when harvesting a crop with a lot of water, the slip of the discharged matter in the rear cover 31 and the guide plate 32 can be promoted by the water-repellent material, so that the stagnation or clogging of the discharged matter in the dust discharging unit 17 is prevented. Can be prevented.
