By the way, in the structure of the said patent document 1, the conveyance and dispersion | distribution of the second object returned from a reprocessing apparatus are mainly performed by the rocking motion of a rocking | flux sorting board. Due to the relationship between the opening direction of the reprocessing apparatus and the rotation direction of the reprocessing cylinder, the rotation of the reprocessing cylinder does not contribute much to dispersing the second object on the swinging sorting panel. For this reason, the second object from the reprocessing apparatus tends to be biased just below the discharge port of the reprocessing apparatus. In addition, the threshing threshed by the barrel of a threshing apparatus tends to fall to one side vicinity of the rotation downstream of a barrel rather than the left and right center part of a rocking | fluctuation sorting board. Therefore, in the vicinity of the rotational downstream side of the barrel of the swing sorting panel (near the immediate side of the discharge port), the threshed matter and the second crop are concentrated and easily deposited, and the ability to sort out the threshed matter and the second crop in the swing sorting panel is reduced.

That is, when the threshing material which fell from the barrel 51 through the crimp net 60 to the upper surface of the feed pan 183 falls from the rear end side of the feed pan 183 to the front end of the chaff sieve 184, the tuyere fan It is made to balloon by the selection wind from 53. FIG.
The second pre-air passage 203 is formed such that the sorting wind from the tuyere fan 53 moves from the front side to the rear side of the grain pan 191 via the lower surface side of the pre-winding body 205. In other words, the second pre-air passage 203 is formed so that the sorting wind from the tuyere fan 53 moves from the front lower side of the chaff sheave 184 toward the rear upper side of the chaff sheave 184. That is, grains and dust falling from the chaff sieve 184 to the grain pan 191 and the grain sheave 185 by the sorting wind from the tuyere fan 53 are ballooned.
In this case, among the threshing products which moved to the upper surface of the chaff sieve 184, the straw flakes (light weight) of the lower layer side near the upper surface of the chaff sieve 184 are transferred to the upper layer side by the sorting wind, and the chaff sieve 184 is carried out. The amount of straw crumbs falling from it is reduced. Moreover, the grain (weight) of the upper layer of threshing material moves to the lower layer side by the specific gravity sorting effect of the chaff sieve 184, and the balloon of the sorting wind from the tuyere fan 53, and it falls early from the chaff sieve 184. The specific gravity sorting action of the chaff sieve 184 is encouraged by the sorting wind from the tuyere fan 53, thereby improving its sorting processing capability (selection accuracy).
In addition, the sorting wind from the tuyere fan 53 supplied from the main sorting winder 201, the first pre-air 202 and the second pre-air 203 is sucked into the above-mentioned exhaust fan 61 and the suction discharge port ( 189 or from the rocking outlet 190. As a result, straw debris, dust, and the like in the threshing material are discharged out of the device from the rear portion of the threshing machine housing 180.

It is fastened. The cylinder flange 221 which penetrated the reduction shaft 212 is fixed to the lower end side of the U-shaped cover 220 by welding etc. The ring part which protrudes downward of the cylinder flange 221 is fitted in the conveyance end side of the reduction cylinder 58. As shown in FIG. The case body 231 of the drive case 230 is bolted to the upper end side of the U-shaped cover 220 and the upper end side of the reprocessing case 216. The conveyance end part of the reduction shaft 212 is rotatably supported by the site | part of the U-shaped cover 220 side among the case main bodies 231.
As shown in FIG.10 and FIG.12, the opening end side of the U-shaped cover 220 in the feed end side of the reduction cylinder 58, and the upper side of the rear part of the reprocessing case 216 communicate. In other words, the opening end side of the U-shaped cover 220 and the upper side of the rear part of the reprocessing case 216 are connected through the upper feed hole 222. The second article inherited by the reduction conveyor 160 is transferred into the reprocessing case 216 on the reverse u-turn when viewed from the side via the upper transfer port 222. As shown in FIG. 12, the peripheral walls 216a and 220a of the upper transfer port 222, that is, the peripheral walls facing each other on the grain tank 7 side in the reprocessing case 216 and the U-shaped cover 220. 216a and 220a (parts along the flow direction of the second article) are straight when viewed in plan so as to be coplanar along a common tangent TL spanning the inner circumference of the reprocessing case 216 and the U-shaped cover 220. Face to face By the combination of the above-mentioned structure and the reprocessing cylinder 161 which rotates counterclockwise in FIG. 12, the second object inherited by the reduction conveyor 58 reduces the conveyance force by the scraping blade 214 much. It is smoothly conveyed to the reprocessing case 216 along the circumferential walls 216a and 220a of the upper conveyance port 222, without making it.

Equipped. The lower end side of the reprocessing shaft 217 is rotatably supported by the bottom plate of the reprocessing case 216. The upper end side of the reprocessing shaft 217 is rotatably supported by a portion of the case body 231 of the drive case 230 on the reprocessing case 216 side. At least an upper portion of the reprocessing shaft 217 is provided with a scraper plate 224 for preventing the second material (straw scraps, etc.) from being wound around the reprocessing shaft 217. The scraper plate 224 of the embodiment extends from the upper inner surface of the reprocessing case 216 to the lower inner surface, and is wound to rotate integrally with the reprocessing shaft 217. As is apparent from FIG. 12, the radial length R of the scraper plate 224 (the length from the center of the reprocessing shaft 217 to the radially outer side end portion of the scraper plate 224) is measured. It is set to about half of the radius in plan view of the processing case 216.
With the above configuration, when transferring the second object to the reprocessing case 216 side through the upper transfer hole 222, the outer side of the radius of the circumferential walls 216a and 220a of the upper transfer hole 222 and the scraper plate 224 The second article is guided and introduced into the gap between the side ends, and the rotation of the scraper plate 224 can be reliably avoided to prevent the second article from inheriting. Therefore, the second article in the reprocessing case 216 can be inherited very smoothly. In addition, from the relationship between the presence of the scraper plate 224 and the guide / injection direction of the second product, the wrinkling and detachment of the straw flakes to the upper portion of the reprocessing cylinder 161 (upper portion of the reprocessing shaft 217) can be suppressed.
The scraper plate 224 on the reprocessing shaft 217 has a feed auger 243 formed in a set of spirals, and a plurality of second processing teeth 225 for stirring the second object inherited from the reduction conveyor 160; And discharging a plurality of sheets (two sheets in this embodiment) for discharging and scattering the second object from the lower feed port 223 of the reprocessing case 216 communicating with the inlet 215a of the second discharge portion 215.

An accommodating tooth 227 is attached to an inner surface side of the reprocessing case 216 so as to pass between two sets of two process teeth 225. That is, in the reprocessing case 216, as the reprocessing cylinder 161, the scraper plate 224, a set of transfer augers 243, a plurality of second processing teeth 225, and a plurality of receiving teeth ( 227 and two discharge blades 226 are housed.
In the embodiment shown in FIGS. 9-11, the group of the 2nd process tooth 225 and the receiving tooth 227 is located between the both conveyance ports 222 and 223 in the reprocessing case 216. As shown in FIG. Two discharge blades 226 face the lower feed port 223 of the reprocessing case 216. In addition, the upper and lower lengths Lu of the upper conveying hole 222, the upper and lower lengths Ld of the lower conveying hole 223, and the upper and lower lengths Lc between both of the conveying holes 222 and 223 have substantially the same dimensions. It is set (Lu? Ld? Lc). Moreover, each accommodating tooth 227 is integrally provided in the reprocessing case 216 so that it may protrude to the outer surface side of the reprocessing case 216, and comprises the strength member of the reprocessing case 216. As shown in FIG.
The second article conveyed into the reprocessing case 216 through the upper transfer hole 222 by the scraping blade 214 of the reduction conveyor 160 is processed twice while falling from the upper side of the reprocessing case 216 to the lower side. The tooth 97 and the receiving tooth 100 are reprocessed (such as detachment of the embrittlement grain or the unwrapping of straw crumbs). The processed second article transferred to the lower side of the reprocessing case 216 is discharged from the lower conveyance port 223 toward the inclined inner surface of the second article discharge unit 215 by the discharge blade 98.
As shown in FIGS. 8-11, the drive case 230 is attached to the upper end side of the reduction cylinder 58 (U-shaped cover 220), and the upward opening side of the reprocessing case 216. As shown in FIG. The drive case 230 is comprised from the plate-shaped case main body 231 and the case lid 232 which detachably covers this. On the case body 231, a pulley belt transmission mechanism 233 for transmitting the rotational power of the reduction conveyor 160 to the reprocessing cylinder 161 is disposed.
In the embodiment, the driving pulley 234 is fixed to the protruding end portion of the reduction end shaft 212 supported by the case main body 231. Similarly, the driven pulley 235 is fixed to the protruding end of the feed start end of the reprocessing shaft 217 supported by the case main body 231. An endless belt 236 is wound around these spur gears 234 and 235. The endless belt 236 is configured to adjust the tension by the tension roller 237. By the action of the pulley belt transmission mechanism 233, the reprocessing cylinder 161 is rotated counterclockwise (reduction conveyor 160 around the reprocessing shaft 217 in FIG. 12 using the rotational power of the reduction conveyor 160). Rotation drive in the same direction as). The case lid 232 is bolted to the case main body 231 in the state which covered the pulley belt transmission mechanism 233 from upper direction. When the bolt is removed and the case lid 232 is removed, the pulley belt transmission mechanism 233 is exposed on the case body 231. The power transmission mechanism from the reduction conveyor 160 to the reprocessing cylinder 161 is not limited to the pulley belt transmission mechanism 233 described above, but may be a sprocket chain type or a gear type.
By the said structure, when the uncut grain stem of a package is harvested by the harvesting | reaping apparatus 3, and the harvested grain stem supplied from the harvesting apparatus 3 was threshed by the threshing apparatus 5, it fell down from the threshing apparatus 5 The threshing grains are sorted by the rocking | fluctuation sorting board 52. As shown in FIG. Sizing as the first material sorted by the rocking | fluctuation sorting board 52 is collected by the 1st conveyor 55 in the grain tank 7. In addition, when the mixture of grain and straw crumbs which were sorted by the rocking | waste sorting board 52 fell on the conveyor 2, the second article will be transferred from the conveyor 56 to the reduction conveyor 160. It is inherited and conveyed from the reduction conveyor 160 into the reprocessing case 216.
The second article introduced into the reprocessing case 216 from the transfer end side (upper side) of the reduction conveyor 160 by the scraping blade 214 is applied to the second treatment tooth 225 and the receiving tooth 227. After reprocessing (such as desorption of the pellets and separation of straw debris, etc.), the discharge blade 226 is discharged from the second discharge portion 215 to the upper surface of the feed pan 183 to swing the shake screening plate 52. Is screened again). Therefore, the grain which remained in the 2nd thing falls to the 1st conveyor 55, and is carried in to the grain tank 7. In addition, the straw crumbs in the second article are discharged out of the apparatus from the suction discharge port 189 or the swing discharge port 190 of the exhaust fan 61 via the upper surface of the chaff sheave 184.
In addition, although the second conveyor 56, the reduction conveyor 160, and the reprocessing cylinder 161 rotate in interlocking manner, each rotation speed is different. In the embodiment, the reduction conveyor 160 rotates at a higher speed than the second conveyor 56, and the reprocessing cylinder 161 rotates at a higher speed than the reduction conveyor 160. That is, the conveyed amount per unit time of the reduction conveyor 160 is made larger than the conveyed amount per unit time of the second conveyor 56, and the conveyed amount per unit time of the reprocessing ridge 161 is larger than the conveyed amount per unit time of the reducing conveyor 160. By increasing the number, the second article is prevented from clogging during conveyance from the reduction conveyor 160 or the reprocessing cylinder 161.
(6). Drive structure of swinging screen
Next, the drive structure of the swing selector 52 will be described with reference to FIGS. 13A and 13B. As shown in Fig. 13 (a), a pair of left and right support bosses 251 are bolted in a downwardly protruding position to the lower surface side of the rear portion of the swing sorting plate 52. The guide roller 253 is rotatably provided in the one end side (left and right outer side) of the horizontal roller shaft 252 inserted and fixed to the boss | hub part of each support boss body 251. The left and right guide rollers 253 are supported by the rear guide rails 182 so as to be able to roll. The other end side (left and right inner side) of each roller shaft 252 is rotatably supported at the one end side of the front-back direction of the swinging link 254 through a bearing member (not shown). On the other end side of the swinging link 254 in the front-rear direction, the length middle portion (reciprocating shaft portion 162y described later) of the swinging shaft 162 is rotatably supported through the bearing member 255.
The swing shaft 162 is for converting its rotational motion into a reciprocating motion of the swing sorting plate 52 and is mounted across the left and right side walls 180a and 180b of the threshing housing 180 (both beam beam shape). Is supported). The swing shaft 162 of the embodiment includes a first rotating shaft portion 162x supported by the left wall 180b of the sheller housing 180 and a second rotating shaft portion supported by the right wall 180a of the sheller housing 180. 162z and the reciprocating shaft part 162y which connects both rotating shaft parts. As shown in FIG. 13, the shaft center (rotation center) of both rotating shaft parts 162x and 162z is located on the same axis line. The shaft center of the reciprocating shaft portion 162y extends substantially in parallel with the shaft center (rotational center) of both the rotation shaft portions 162x and 162z in an eccentric state. In addition, on the protruding end side (the supporting shaft portion 162x1 to be described later) projecting outward from the threshing housing 180 in the first rotating shaft portion 162x, the rotational power from the tuyere fan shaft 156 is transmitted through the transmission belt 257. Receiving drive input pulley 256 is fixed.
Each rotating shaft portion 162x (162z) is constituted by a supporting shaft portion 162x1 (162z1) serving as a rotation center and a boss portion 162x2 (162z2) that is integrally addressed thereto. The left and right front ends of the reciprocating shaft portion 162y are inserted into each boss portion 162x2 (162z2). The boss portion 162x2 of the first rotary shaft portion 162x and the front end side of the reciprocating shaft portion 162y are detachably connected by the key 258 and the pin 259. The boss portion 162z2 of the second rotary shaft portion 162z is formed with a slit 260 (notch groove) communicating with the boss hole of the boss portion. The second rotary shaft portion 162z and the reciprocating shaft portion 162y are connected so as not to be pulled out by welding using the slit 260 while the front end side of the reciprocating shaft portion 162y is inserted into the boss portion 162z2 (Fig. 13). (a) and FIG. 13 (b) shows the welded portion as w]. Accordingly, the swing shaft 162 of the embodiment is configured to be separated into two members by a set of the first rotation shaft portion 162x, the reciprocating shaft portion 162y, and the second rotation shaft portion 162z. Consideration has been given to the ease of separation of 162). In this case, there is a merit that maintenance work such as replacement of the bearing member 255 supporting the swing shaft 162 is easy, for example.
When both rotation shaft parts 162x and 162z rotate coaxially by the rotational power which passed through the drive input pulley 256 from the tuyere fan shaft 156, the reciprocating shaft part 162y will move around the shaft center of both rotation shaft parts 162x and 162z. To circular motion. The circular motion of the reciprocating shaft portion 162y is converted into a reciprocating motion along the rear guide rails 182 of both the supporting boss bodies 251 through both swinging links 254. As a result, the swing selector 52 is reciprocated in a forward obliquely downward to an obliquely upward upward (swinging motion).

Therefore, the space occupied in the left and right width directions of the threshing apparatus 5 and the grain tank 7 can be enlarged without enlarging the left and right width directions of the combine, thereby improving the threshing capacity and the grain storage capacity without increasing the combine. It has an effect that can be planned.
Further, as described above, the reprocessing so as to overlap the region of the feeding chamber 173 of the threshing apparatus 5 when viewed from the side between the graining apparatuses 57, 159 and the second reducing apparatus 58, 160. Since the apparatus 59 is located, it is possible to return to the supply chamber 173 of the threshing apparatus 5 smoothly, without scattering the reprocessed 2nd thing by no operation. Therefore, it becomes possible to ensure the distance which the processed second object moves while sorting in the threshing apparatus 5 enough, and it has the effect that it can contribute to the improvement of the sorting process capability in a combine.
As is evident from the substrate and from FIGS. 6, 10 and 11, the rotary shaft 212 of the reduction conveyor 160 in the second reduction devices 58, 160 and the reprocessing device 59 are provided. Since the rotating shaft 217 of the reprocessing cylinder 161 is extended in parallel, it is possible to lengthen the length of the reprocessing cylinder 161 in the direction of the rotating shaft 217 along the reduction conveyor 160. Become. Therefore, a sufficient distance for the second article to move in the reprocessing apparatus 59 can be secured for reprocessing (recursion), thereby improving the reprocessing function of the second article by the reprocessing cylinder 161. It has the effect that it can be planned.
10 and 12, the lower part of the reprocessing apparatus 59 communicates with the threshing apparatus 5 through the second discharge portion 215, and the threshing apparatus ( Since the discharge port 215b of the second discharge portion 215 is opened in front of the support frame 218 for supporting the crimp net 60 on one side wall of the 5), the secondary discharge portion 215 Can be smoothly guided and discharged from the discharge port 215b to the front side in the threshing apparatus 5 (front side of the swing sorting plate 52) without being scattered without any manipulation. have. For this reason, it is possible to suppress the possibility that the processed second article is locally deposited, for example, in the vicinity of the second article discharge part 215, and further contributes to the improvement of the sorting capability in the combine. Has
6 to 11, the second material is reprocessed on the conveying end side of the second reducing devices 58 and 160 which return the second product after threshing sorting to the threshing apparatus 5, as clearly shown in the above description and FIGS. A combine having a reprocessing device 59 for the purpose of being used, wherein the lower portion of the reprocessing device 59 is located at a lower portion than the rotation shaft 158 of the barrel 51 in the threshing device 5. The lower part of the reprocessing apparatus 59 is connected to the threshing apparatus 5 through 215, and the lower part of the reprocessing apparatus 59 is connected to the upper side of the rear part of the second discharge portion 215. The second object is hard to collide with the barrel 51, the crimp network 60, etc., and can be transferred into the threshing apparatus 5 from a position lower than the rotation shaft 158 of the barrel 51. The collision and the like of the barrel 51 and the like have the effect of suppressing detachment and crushing of the processed second product.
As clearly shown in the above description and FIGS. 10 to 12, the second reduction apparatus in a posture in which the graining apparatuses 57 and 159 for conveying the first product after threshing sorting to the grain tank 7 are extended in the longitudinal direction. It is disposed in front of the 58, 160, the outer shape of the second discharge portion 215 is formed in a funnel shape spreading obliquely downward in front of the one side wall of the threshing apparatus 5 as it goes forward and downward The second discharge portion 215 is inclined to approach 180a, and the second discharge portion 215 is disposed so as to partially overlap with the middle length portion of the grains 57 and 159 when viewed from the side, so that the left and right widths become narrower toward the front. The secondary discharge portion 215 formed is extended forward by using a gap space between the threshing apparatus 5 and the grain apparatuses 57 and 159. For this reason, it has the effect that it can disperse | distribute and disperse | distribute widely the processed 2nd thing in the said threshing apparatus 5. In addition, since the secondary discharge portion 215 is inclined to approach the threshing apparatus 5 downwardly, the secondary discharge portion 215 is smoothly processed from the lower portion of the reprocessing device 59 through the secondary discharge portion 215. There is also an advantage that the second guide can be dropped.
6, 7, and 10 to 12, the front end side of the discharge port 215b in the second discharge portion 215 is viewed from the side of the threshing apparatus 5, as clearly seen from the substrate and FIGS. The rear end side of the discharge port 215b is located on the chaff sieve 184 of the threshing apparatus 5, and thus, the second discharge part 215 The discharge port 215b is widely opened in one side wall 180a of the threshing apparatus 5, and the treatment is performed from the discharge port 215b of the second discharge part 215 toward the feed pan 183. The finished second article can be efficiently guided and released. Therefore, it is possible to sufficiently secure the distance that the processed second article moves while being sorted in the threshing apparatus 5, and has the effect of improving the sorting capability of the combine.
As is clearly seen from the above description and FIGS. 9 to 11, the second article is reprocessed on the feeding end side of the second reducing devices 58 and 160 which return the second article after threshing screening to the threshing apparatus 5. As a combine having a reprocessing device 59 for communicating with the reprocessing device 59, the reprocessing device 59 communicates with an upper feed port 222 communicating with the second reducing devices 58 and 160 and the threshing device 5. The lower conveyance port 223 is formed, and a plurality of receiving teeth 227 is provided between the upper conveyance port 222 and the lower conveyance port 223 of the inner surface side of the reprocessing device (59). On the other hand, the reprocessing cylinder 161 provided in the reprocessing apparatus 59 is provided with the processing tooth 225 located between the said accommodating teeth 227, and in the said reprocessing apparatus 59, said 2 The bulge is configured to move from the upper feed hole 222 toward the lower feed hole 223 Control because, the second beonmul succession from the two-time reduction device (58, 160) is able to fall by its own weight the inside of the material processing device (59). For this reason, the said process tooth 225 and each said accommodation tooth 227 only need to be provided with the function of desquamation of a lodging grain and the lump of rice straw, and the conveyance function of a second object becomes unnecessary. Therefore, it has the effect that each said process tooth 225 and each said accommodation tooth 227 can be made into a simple structure, without reducing the reprocessing (retreatment) ability.
As is apparent from the substrate and FIG. 10, the upper and lower lengths Lu of the upper conveying hole 222, the upper and lower lengths Ld of the lower conveying hole 223, and the both conveying holes 222, Since the upper and lower lengths Lc between the 223s are set to substantially the same dimensions (Lu ≒ Ld ≒ Lc), the reprocessing apparatus 59 is divided into approximately three equal parts, and the reprocessing apparatus 59 is reprocessed. It is possible to reduce the risk that each processing tooth 225 and each receiving tooth 227 remain in the reprocessing device 59 for a long time while maintaining the (re-bending) capability. Therefore, it has the effect that the blockage in the said reprocessing apparatus 59 can be suppressed, and the processed second object can be returned to the threshing apparatus 5 side smoothly.
As apparent from the substrate and FIGS. 8 to 11, the receiving teeth 227 protrude to the outer surface side of the reprocessing device 59, and the strength member of the reprocessing device 59 is formed. Since each receiving tooth 227 itself plays the role of the reinforcement member with respect to the said reprocessing apparatus 59, since it is comprised. For this reason, the rigidity of the said reprocessing apparatus 59 (reprocessing case 216) can be improved.
As is clearly seen from the above description and FIGS. 10 to 12, the second article is reprocessed on the transfer end side of the second reducing devices 58 and 160 which return the second article after threshing screening to the threshing apparatus 5. As a combine having a reprocessing device 59 for the purpose, a rotary shaft 212 of the reduction conveyor 160 in the second reduction devices 58 and 160 and a reprocessing copper in the reprocessing device 59 The rotating shaft 217 of the 161 extends in parallel and is reduced in the second of the circumferential walls of the upper feed hole 222 connecting the second reducing devices 58 and 160 and the reprocessing device 59. Portions 216a and 220a along the flow direction of the second product from the apparatuses 58 and 160 to the reprocessing apparatus 59 are formed on the inner circumference of the second reducing apparatus 58 and 160 and the reprocessing apparatus 59. Since it has a shape along the common tangent TL that is spread, the second article inherited to the reduction conveyor 160 is Along the portions 216a and 220a of the circumferential wall of the upper conveyance port 222, the radially outer side of the reprocessing cylinder 161 is not reduced without significantly reducing the conveyance force by the conveying end side of the reduction conveyor 160. To the reprocessing device 59 side. Therefore, it is possible to smooth the inheritance of the second product from the second reducing devices 58 and 160 to the reprocessing device 59, thereby preventing the residence during the inheritance and preventing the second reducing devices 58 and 160. And the blockage between the reprocessing device 59 can be suppressed.
As apparent from the substrate and FIGS. 10 to 12, at least an upper portion of the rotary shaft 212 in the reprocessing cylinder 161 prevents the second article from being wound onto the rotary shaft 212. And a gap between a portion 216a, 220a along the common tangent of the circumferential wall of the upper transfer hole 222 and a side end portion of a radially outer side of the scraper plate 224. Since the second article is configured to be fed in the direction of the second article, the rotation of the scraper plate 224 is caused by the succession of the second article when the second article is conveyed to the reprocessing device 59 through the upper conveying port 222. Obstructions can be reliably avoided. Therefore, there is an effect that the second article can be transferred very smoothly in the reprocessing apparatus 59. In addition, there is an advantage that the wrinkling and detachment of the straw scraps to the upper portion of the reprocessing cylinder 161 can also be suppressed from the relationship between the presence of the scraper plate 224 and the guide / injection direction of the second product.
As clearly seen from the substrate and FIGS. 9 to 11, the scraper plate 224 extends from the upper inner surface of the reprocessing device 59 to the lower inner surface, and the scraper plate 224 of the scraper plate 224. Since a plurality of processing teeth 225 are attached to a position lower than the upper feed hole 222, the presence or absence of the scraper plate 224 causes the wrinkling or detachment of straw flakes to the entire reprocessing cavity 161. It has the effect that it can support each said process tooth 225 stably, suppressing.
