FIG. 1 is a side sectional view of a threshing apparatus to which the present invention is applied. The threshing apparatus 1 is installed on a machine body frame 2 of a traveling machine body to which a pretreatment unit of a self-removing combine machine is connected. In the threshing apparatus 1, an upper handling chamber (threshing portion) 4 and a lower sorting chamber 6 are separated by a receiving net 3. A cylindrical handling cylinder 7 and a processing cylinder 8 extending in the forward / backward direction (front / rear direction) of the combine are supported in the handling chamber 4 so as to be rotatable around an axis. The sorting body 9 is supported by a back-and-forth reciprocating drive (oscillation drive), and a tang fan 11 and a dust exhaust fan 12 are installed before and after the sorting chamber 6, respectively.

  Grain harvested by the pre-processing unit and transported to the front (left) front end of the traveling machine body is inserted into the handling chamber 4 by the feed chain 13 extending in the front-rear direction along the handling chamber 4. In this state, the stock market side is sandwiched and conveyed rearward along the handling chamber 4. In this way, the cereals passing through the handling chamber 4 are handled and thrown down by the handling cylinder 7 and the processing cylinder 8 that are rotationally driven to be slaughtered, and the slag is conveyed behind the feed chain 13. Passed to body 14. On the other hand, the processed material that is handled by the handling cylinder 7 includes grains such as straw and swarf and the like, falls through the receiving net 3 and is introduced into the sorting chamber 6. .

  The waste conveyed rearward by the waste conveying body 14 is discharged as it is or after being introduced into the post-processing unit (cutter unit) 16 from the rear end portion of the threshing apparatus 1. The waste introduced into the post-processing unit 16 is cut out and then discharged outside the machine.

  After the processed material introduced into the sorting chamber 6 is swung and sorted by the swing sorter 9, the grain and sawdust and the like are separated by the sorting wind that is raised diagonally and rearward by the Kara fan 11 and the dust exhaust fan 12 and the like. Sorted out. Specifically, with the sorting wind, the treated material is slightly affected by the sorting wind and the first thing that falls slightly forward from the central portion in the front-rear direction of the sorting chamber 6 with little influence from the sorting wind. Sorted into No. 2 that falls backward from No. 1 and soot and the like blown up to the dust exhaust fan 12 side of the sorting chamber 6 under the influence of sorting wind and the like.

  The 1st thing is conveyed by the 1st spiral 17 and the whipping cylinder 18, and is accommodated in the glen tank 19 as a grain. The second product is reduced again by the second spiral 21 and the reduction cylinder 22 to the upper side of the swinging sorter 9 in the sorting chamber 6 and wind-selected. Sawdust and the like are discharged out of the machine by the dust exhaust fan 12 and the like.

  FIG. 2 is a perspective view of the swing sorter. FIG. 3 is a perspective view of the oscillating sorter with the Glen pan, chaff sheave and strollac removed. The swing sorting body 9 described above includes a frame portion (swing body) 9a supported by the frame body 1a (see FIG. 1) of the threshing apparatus 1 through the swing link 23 so as to be able to swing back and forth. The frame portion 9a is configured by connecting and fixing a pair of plate frames 24, 24, which are long in the front-rear direction facing each other, by a plurality of plate-like connection frames 25 extending in the left-right direction.

  Between the pair of plate frames 24, 24, a grain pan (transfer plate) 26 that receives, on the upper surface side, a processed product that has passed through the receiving net 3 from the handling chamber 4 and moves it to the rear side, and a grain pan 26 The chaff sheave 27 for sorting and dropping (leakage) the processed material that has been transferred by the grain pan 26 and the rear side of the chaff sheave 27 and transporting the long spear contained in the processed material rearward, and the processed material. Strollac 28 that drops down the short rice cakes and grains contained in the above as the second item, and a Glen sieve 30 that receives the processed material leaked from the chaff sheave 27 and selectively drops it (see FIG. 1) and are fixedly installed. The Glen pan 26, chaff sheave 27, stroller 28 and Glen sheave 30 are provided on the frame portion 9a so as to reciprocate back and forth integrally with the frame portion 9a.

Next, the configuration of the Glen pan 26 will be described in detail with reference to FIGS.
The Glen pan 26 is configured by bending upward the front end portion of a rectangular plate-like member that extends in the horizontal direction and the longitudinal direction is the longitudinal direction, and the bent portion extending upward becomes the wall portion 26a, and the other portions The upper surface side is a transfer surface 26b that spreads forward, backward, left and right. A flat front portion 29 and a rear end portion 31 are formed at the front and rear end portions of the transfer surface 26b, and a transfer portion 32 is formed at a position between the front portion 29 and the rear end portion 31 of the transfer surface 26b. ing. In addition, a plurality of partition plates (closer plates) 33 are fixedly installed (fixed) on the transfer surface 26b.

  4 and 5 are a side view and a rear view of the main part showing the configuration of the transfer part and the partition plate. As shown in FIGS. 2 and 4, the transfer portion 32 includes a mountain surface 32a that gently slopes upward toward the rear, which is the downstream side (transfer side, downstream side), and a flat flat surface. The surface 32b is configured by alternately arranging toward the transfer side, and has a wave shape as a whole. When the Glen pan 26 is moved back and forth, the reaction product accumulated on the front portion 29 or the flat surface 32b moves over the mountain surface 32a and moves to the flat surface 32b on the downstream side. That is, by moving the rocking sorter 9 back and forth, the processed materials are sequentially transferred backward.

  Each of the plurality of partition plates 33 inclines upward from the transfer surface 26b of the Glen pan 26 and is inclined outward (to the left) in the transfer direction, and falls from the handling chamber 4 to the left and right sides of the Glen pan. This is a close-up plate that draws a part of the processed product biased to the inner side of the machine body on one side to the outer side of the machine body on the other side of the left and right in the transfer process by the above-described longitudinal movement. In other words, the partition 33 is used for diffusing and transporting the processed product so that the left and right amounts of the processed product on the downstream side are more equal than those on the upstream side. For this reason, of the front and back surfaces of the partition 33, the left side surface with a small amount of processed material falling becomes the approach surface (working surface) 33a that brings the processed material together.

  The attachment of the partition plate 33 to the grain pan 26 will be described. The lower end portion of the partition plate 33 is formed in a wave shape corresponding to the wave shape of the transfer portion 32 and abuts against the flat surface 32b of the transfer portion 32. Further, a plate-like contact piece 33 b that contacts the rear end portion 31 in a planar shape extends from the rear end portion 31 side of the lower end portion of the partition plate 33. The abutting portion between the partition plate 33 and the transfer surface 26b is bonded and fixed (fixed) by spot welding or the like, so that the partition plate 33 is fixedly mounted on the transfer surface 26b of the Glen pan 26.

  Incidentally, in the illustrated example, two partition plates 33 are arranged side by side, the right partition plate 33 is formed in the range from the downstream side of the transfer unit 32 to the front portion of the chaff sheave 27, and the left partition plate 33 is It is formed in a range from the upstream side of the transfer part 32 to the rear end part 31.

  The Glen pan 26 having the above operation is detachably attached and fixed to the frame portion 9a, and the entire transfer surface 26b, the entire surfaces of each partition plate 33, and the entire upper surface of the contact piece 33b are subjected to water repellent finishing. For this reason, a fluororesin film 34 is formed. As described above, by performing the water repellent treatment, it is possible to minimize the degradation of the sorting performance when the processed product is wet. Incidentally, the water-repellent treatment may be performed collectively with the partition 33 attached to the Glen pan 26, or may be performed on the partition plate 33 and the Glen pan 26 before attaching the partition plate 33 to the Glen pan 26, respectively.

  FIG. 6 is a perspective view of the main part showing the mounting structure of the Glen pan. The Glen pan 26 is located between the left and right mounting brackets 36, 36 disposed in the opposing inner surfaces of the pair of left and right plate frames 24, 24 and extending in the front-rear direction, and the rear ends of the pair of mounting brackets 36, 36.
