Description

The present invention relates to an oscillating sorting device that reduces the second reductant separated by the wind sorting unit of a threshing machine to the upper surface of the oscillating sorter and diffuses it to the sorting width.

  Conventionally, in order to concentrate the second reduced product falling through the processing cylinder etc. on one side of the swing sorting device (the lower side of the handling cylinder rotation), the guide plate that diffuses to the sorting width is bent and the inclined surface There is a known technique for forming (see, for example, Patent Document 1). In addition, a guide plate is provided so that the non-sorted material is evenly distributed on the grain pan of the rocking sorter, and the upper edge side of the guide plate is bent laterally outward to bring the second reduced product toward the center of the sorting width. There exists what was comprised (for example, refer patent document 2). However, it has a diffusing structure through a jumping blade and a processing cylinder in which the discharge direction is widened, and the fall amount and the discharge position are not stable with respect to the guide plate.

Japanese Utility Model Publication No. 62-162937 (page 2-3, Fig. 1-2) Japanese Utility Model Publication No. 05-60239 (page 3-4, Fig. 2-4)

  Many handling wholesales that flow from the front of the handling room to the right side of the rocking sorter and the second reductant together cause an imbalance in the sorting layer, resulting in a lack of sorting wind and a good grain recovery rate. There are problems such as lowering. In order to prevent this, the handling material and the second reduced product are supplied to the individual passages and diffused by the combination of the conveying means for the second reduced product and the guide plate.

  The present invention that eliminates such problems is a threshing comprising a second reduction device that discharges the second reduced product separated by the wind sorting unit to the upper surface of the rocking sorter by means of a conveying means connected to a masher. In this machine, a guide plate is attached to the starting end side of the swinging sorter, and a lateral transfer device protruding from the swinging sorter is arranged to straddle the guide plate. It was configured to supply to the passage.

  The upper edge of the guide plate is bent toward the masher side to form an inclined surface, the end of the lateral transfer device is faced above the inclined surface, and the center of the selection width is guided while the reduced product to be discharged is guided inward. The guide plate diffused in the direction.

  A spiral conveyor in which treated teeth are implanted is installed in the lateral transfer device, and the second reduced product is treated while being transported to discharge the entire amount to the outer passage of the swinging sorter.

  Since the form to be discharged onto the rocking sorter 1 has been changed from the conventional jumping method to the lateral transfer device A, the second reduced product is easily discharged to a predetermined position, and the upper edge on the cerealing machine E side. The reduced product is guided to the inner side by the bent inclined surface 5 so that almost the entire amount of the second reduced product can be supplied to the outer passage 37 where the sorting layer is thin, and the diffusion toward the center P of the sorting width can be performed stably. The performance was further improved. Further, since the lateral transfer device A in which the spiral conveyor 43 is installed is used, the momentum of the grains that collide with the guide plate 2 is attenuated and diffusely reflected on the feed pan 30 as compared with the conventional jumping method. Therefore, there is an effect that it is possible to prevent the grains that are discharged without being selected.

  Next, the embodiment of the present invention will be described with reference to an example diagram of a threshing unit mounted on a combine. FIG. 1 is an overall side view of the combine, and FIG. The structural outline is that a threshing part B is mounted on a machine base 11 supported by a pair of left and right crawler traveling devices 10, and a chopping part D that can be moved up and down is attached to adjust the cutting height. The tilted corn straw is levitated by the plate 12, and the corn straw cut by the cutting blade 13 is pinched and conveyed by a lifting and conveying device 15 connected to the rear, and is fed to the starting end side of the feed chain 16 installed horizontally on the threshing portion B. It is a cutting and conveying route that can be inherited. A grain removal process is performed by rotation of a handling cylinder 8 in which the harvested cereals inherited by the feed chain 16 are mounted on the handling chamber 7, and the handling material is fed from the surrounding receiving net 20 to the feed pan 30 of the swinging sorter 1. Rough sorting is performed to separate grains and dust while being transported backward by a chaff sheave 21 or the like that falls upward and swings back and forth, and is not connected to the wind selection unit 22 provided below the swing sorting device. It is the structure of the combine which induced | guided | derived the selection thing, isolate | separated the good grain with the selection wind of the arrow a direction, and carried it out of the machine of the threshing part B.

  The sorting path of the threshed handling wholesale is the oscillating sorter 1 that oscillates back and forth, as the grain generated in the handling chamber 7 and unprocessed items and dust leak from the receiving net 20 to become a handling wholesale. After falling to the top and moving to the lower side while undergoing rough selection, the grains were separated into the wind sorting unit 22 after cerealing to the starting end side of the continuous chaff sheave 21, and collected in the most recovery area 23. The finished grain is dropped to the second collection area 25 where the path for carrying out the first grain outside the machine via the conveyor 24 and the second reduced product mixed with the branch leaf adhering grains and a small amount of single grains are disposed at the rear. It is sorted into a path for reduction onto the rocking sorter 1 by the cerealing machine E connected to the number conveyor 28. In addition, dust such as soot is blown off by the sorting wind of the Kara fan 26 provided in front of the wind selection unit 22 and is discharged to the outside by the suction fan 27 disposed on the rear side of the machine body. It is a thing.

  FIG. 3 is a side view showing the starting end side of the swing sorter. The guide plate 2 which is the gist of the present invention is combined with the plan view of FIG. 4 and the front view of FIG. Explaining the joint structure, a feed pan 30 is stretched on the upper surface on the start end side of the swinging sorter 1, and a group of fins 31 connected to the feed pan 30 is attached so as to be adjustable in angle, thereby forming a chaff sheave 21. The rocking and sorting device integrated with the Glen sheave 32 provided in is used to perform rough sorting of unsorted items by the rocking motion of the front and rear.

  Such a lateral transfer device A that discharges onto the feed pan 30 protrudes from the outer plate 33 of the wind selection chamber 22 above the swinging sorter 1, and the right guide plate 35 and the guide plate fixed to the feed pan 30 are provided. 2, a discharge cylinder 36 is opened on the inner side, and a processing cylinder in which processing teeth 44 are implanted on the outer periphery of the spiral conveyor 43 is installed in the lateral transfer device A so that unprocessed materials mixed in the second reduced product are mixed. It is made into the structure made into a single grain during horizontal conveyance.

The second reduced product after the treatment is discharged into the outer passage 37 indicated by the arrow b, and is a passage that is diffused together with the handling material falling from the upper receiving net 20 on which the handling cylinder 8 rotates,
The handling goods in the direction of the arrow C falling from the lower side where the handling cylinder 8 rotates flows down into the middle passage 38, and the handling goods are mainly supplied to the middle passage 38, and the outer passage 37 described above has two parts. This is separated into diffusion passages for supplying the reductant. Further, the right guide plate 35 for equalizing the handling material that is shifted to the right side of the sorting width is installed on the lower side of the lateral transfer device A so that the front end thereof is joined to the swing sorting frame 40 so as to be swingable. The right-hand passage 45 is configured such that the handling material falling from the handling chamber 7 behind the transfer device A can easily flow into the right side on the swing sorter 1.

  The structure of the guide plate 2 juxtaposed to the right guide plate 35 fixed to the feed pan 30 is such that the upper edge side 41 is bent toward the masher E side and protrudes inward of the swinging sorter 1. The bent inclined surface 5 has an inwardly inclined shape with respect to the end portion 3 of the transfer device A and is swingably mounted together with the feed pan 30. Further, in order to diffuse deeply in the sorting space 42 where the gap between the lower end of the receiving mesh 20 and the feed pan 30 becomes narrow, the release of the second reduced product is once received by the bent inclined surface 5 and then the lead angle C In the same manner as the right guide plate 35 described above, the second reduced product is guided to a position close to the center P of the selection width.

  The diffusion passage formed on the feed pan 30 by the right guide plate 35 and the guide plate 2 in this way is a right passage 45 that diffuses what falls from the rear of the handling chamber 7 from the right side in a plan view, and then the handling chamber 7. An intermediate passage 38 is provided between the guide plate 2 and the outer passage 37 on the left side separated by the guide plate 2 having the bent inclined surface 5. The total amount of the second reduced product formed and processed by the lateral transfer device A is made into three different diffusion passages for flowing into the outer passage 37 to enable the equalization of the sorting layer and effectively perform the rough sorting. It became a dynamic sorting device.

  FIG. 5 is an enlarged view of the guide plate, and the flow of the diffusing grains will be described with reference to the plan view of FIG. 4. The flow of the middle passage 38 sandwiched between the guide plate 2 and the right guide plate 35 will be described. Even when the quantity of handled wholesales increases, the inclined surface 5 made into a bowl-shaped grain that gets over the grain in the direction of arrow D is pressed down and overflows the outer passage 37 to prevent the sorting layer from becoming uneven. The guide plate 2 has a structure in which the phenomenon of the overflow of the transporting grain accompanying the swinging motion is suppressed and the diffusion can be continuously performed toward the center P of the selection width.

  As described above, since the horizontal transfer device A in which the spiral conveyor 43 is installed is used in the form of discharging onto the swing sorter 1 from the conventional jumping structure, the second reduced product is reduced to a predetermined position. In addition, the second reduced product is guided to the center P side of the sorting width by the inclined surface 5 bent toward the cereal mill E side, and discharged into the outer passage 37 where the sorting layer is thin. Both the reduced product and the wholesaler can diffuse over the entire width of the sorting range, and the sorting performance is further improved. In addition, since it is discharged by the spiral conveyor 43, the momentum of the grains that collide with the guide plate 2 is attenuated, and the grains that are irregularly reflected on the feed pan 30 and can be prevented from being discharged out of the machine without being selected. There is.

  In addition, when the amount of handling material that moves on the feed pan 30 increases, the sorting plate may flow over the guide plate 2 adjacent to the middle passage 38 to the outer passage 37 and make the sorting layer non-uniform. In addition, the phenomenon that the inclined surface 5 provided on the guide plate 2 overflows in a bowl shape and suppresses the phenomenon that the non-sorted material is continuously diffused toward the center P of the sorting width even in high-efficiency work. Has the property of reducing layer changes.

  When swinging and sorting grains, etc., in a narrow space, the upper edge of the guide plate with a low height is bent to guide the grains, and the grain layer is equalized over the entire conveying width to stabilize the sorting performance. Can be used for sorting equipment.
