Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing rocking and sorting apparatus for a threshing machine, and has a mining fan for blowing air to a sorting air passage below the upper side of a rocking and sorting rack. It can also be used for threshing machines such as combine harvesters. 2. Description of the Related Art Conventionally, threshing in a threshing machine in a threshing machine and leaking from a receiving net in a threshing machine has conventionally been performed in a sorting room by a rocking sorting rack. In general, combined sorting was performed by combining wind sorting with wind from Karino. However, at the time of sorting in this sorting room, part of the sorting wind blown out from the Karino discharge outlet is partly due to the oscillating structure that exists between the upper surface of the Karino outlet and the lower side of the transfer shelf of the oscillating sorting shelf. Since it is easy to sneak into the required gap along the flow of wind, sorting dust is sent into the gap along with the sneaking sorting wind, and the dust is gradually accumulated and compressed by swinging of the swing sorting shelf, and finally swings. This would damage the moving sorting shelves and the Karafu wind drum. [0003] Accordingly, the present invention provides a sorting wind that wraps around a gap between the lower surface of the transfer shelf of the swinging sorting shelf and the upper surface of the Karamino discharge port.
In addition to preventing the sneaking into the gap, the swinging shelf is blown out to the outside along the left and right side edges of the swing sorting shelf. SUMMARY OF THE INVENTION The present invention provides a threshing machine in which a Karamin 2 that blows air to a sorting air passage W is arranged below the upper side of an oscillating sorting shelf 1 for oscillating and sorting after receiving threshing material. At the lower side 3a of the transfer shelf 3 of the swing sorting shelf 1, a rubber plate 6 is attached so that the lower end edge 6a is in sliding contact with the upper surface 4a of the Karino outlet 4 and the left and right side edges 6b are in sliding contact with the left and right machine wall surfaces 5. Of the threshing rocking sorting apparatus. According to the above arrangement, the threshing material that has been threshed in the threshing room and has leaked from the receiving net has its sorting area located below the threshing room extending from its upper side to its lower side. It falls on a vertically arranged swing sorting shelf 1, is sent from a transfer shelf 3 located on the upper side of the swing sorting shelf 1 to a straw rack via a chaff sheave, and is sorted by a swing transfer action therebetween. The objects fall into the sorting wind path W, where they are sorted by the sorting wind blown by Karino 2 and are sorted and classified into the first kernel and the second one, respectively. Dust is exhausted outside the machine. At the time of this sorting operation, the lower edge 6a of the rubber plate 6 attached to the lower surface 3a near the rear end of the transfer shelf 3 of the swinging sorting shelf 1 facing the Karamino wind drum is moved to the upper surface 4a of the Karino discharge port 4.
By extending it to its full width,
It is possible to prevent a part of the sorting wind blown out from the discharge port 4 from flowing around the gap between the upper surface 4a of the discharge port 4 and the lower side surface 3a of the transfer shelf 3, and further, the rubber plate 6 The transfer shelf 3 is attached in a belt shape along the lower side surface 3a on both left and right sides thereof, and the left and right side edges 6b are slid on the left and right machine wall surfaces 5 so that the left and right sides of the transfer shelf 3 and the left and right sides of the rubber plate 6 are provided. By using the gap formed by the edge 6b and the left and right machine wall surfaces 5 as an air path, a part of the sorted wind wrapping around from the left and right sides of the transfer shelf 3 can be blown out of the machine. As described above, the gap between the lower side surface 3a of the transfer shelf 3 and the upper surface 4a of the discharge port 4 is closed by the lower edge 6a of the rubber plate 6 attached to the entire lower surface 3a of the transfer shelf 3. In addition to preventing the sewage of the sorting wind, the sorting wind spilled by the air path formed by the gap between the left and right side edges 6b of the rubber plate 6 attached to the left and right sides of the transfer shelf 3 and the left and right machine walls 5 is output to the outside of the machine. By blowing through, the accumulation and compression of the sorting dust sent along with the sorting wind into the gap between the lower side surface 3a of the transfer shelf 3 and the upper surface 4a of the Karino discharge port 4 is prevented, and the rocking sorting shelf 1 and Karomi wind drum are damaged. Can be prevented. An embodiment of the present invention will be described with reference to the drawings. Numeral 7 is a threshing machine which can be mounted on a combine.

Is provided so as to extend parallel to and adjacent to the handling cylinder 12 from the vicinity of the discharge port toward the lower side. A receiving net 15 surrounding the outer circumference of the tooth 11 and a processing net 16 surrounding the outer circumference of the processing tooth 13 are disposed below the handling cylinder 12 and the processing cylinder 14, respectively. A dust fan 31 for discharging threshing straw chips sent out without leaking from the processing net 15 and the processing receiving net 16 is provided at a lower position from the terminal end of the processing cylinder 14. In the sorting chamber 9, from the inlet side to the outlet side along the axial direction of the handling cylinder 12, threshing material leaking from the handling net 15 and threshing material leaking from the treatment receiving net 16 are provided. A vertically long swinging sorting shelf 1 that performs sorting while swinging and transferring a processed material is handled and installed with the entrance side of the drum 12 as a good side. By the rotation of a plurality of Karamin blades 18 provided inside the Karamin wind drum 17 below the rocking sorting shelf 1, a sorting wind for threshing is generated and sent to the sorting air passage W. Karamino 2 is arranged and provided. [0010] The swing sorting shelf 1 is a rack-shaped transfer shelf 3 for transferring threshing material to the lower side over the area above the Karamin 2.
And a chaff sheave 19 in which the amount of the threshing material can be adjusted by changing the angle of the shutter-shaped blade toward the lower side following the transfer shelf 3, and a chaff sheave 19 following the chaff sheave 19 toward the lower side. A straw rack 20 for receiving rough waste that does not leak from the handling net 15 and the processing net 16 together with the contaminants that do not leak from the storage rack 20, and a rough selection that leaks from the sheave 19 below the chaff sheave 19. And mesh-like mesh sheaves 21 for further selecting are arranged and provided. The sheave 21 is located below the Glen sheave 21.
The sorted material leaked from the straw rack 20 is provided with a first sorting unit 23 for sorting the first grain by air selection on a fixed first sorting shelf 22 and the sorted material leaked from the straw rack 20 is fixed. A second sorting unit 25 is provided on the second sorting shelf 24 for sorting the second items by wind selection, and the first sorting unit 23 and the second sorting unit 25 are provided.
Then, a separation wind path W is formed in which the wind from each of the Karino 2 is subjected to the sorting wind distributed vertically by the wind splitter 26 located at the Karamino discharge outlet 4. The bottom plate of the Karamin wind drum 17 is extended linearly to the lower side to form a lower lip portion 17a of the Karamin outlet 4 and the end of the lower lip portion 17a and the first sorting shelf 22 The uppermost gutter 28 containing the first grain to be sorted down and fed by the first spiral 27 is connected to the upper side, and the lower side thereof is connected to the first selection shelf 22 in a straight line. The upper end of the first sorting shelf 22 is connected to the upper side of the second trough 30 that accommodates the second item that is sorted down from the second sorting shelf 24 and feeds the second item by the second spiral 29, and the lower side thereof. Are linearly connected to the second sorting shelf 24, and the upper end of the second sorting shelf 24 is arranged and provided so as to be opened outside the machine. [0013] The sorting wind flowing from the upper lip portion 17b into the gap A formed by the lower side surface 3a of the swinging sorting shelf 1 near the end of the transfer shelf 3 and the upper lip portion 17b upper surface 4a of the Karamin outlet 4 is prevented. As shown in FIGS. 3 and 5, the rubber plate 6 is attached over the entire width of the lower side surface 3a of the transfer shelf 3, and the lower edge 6a is slid over the entire upper surface 4a of the upper lip 17b. The gap A is closed. Further, in a gap B between the left and right side portions 3b of the transfer shelf 3 and the left and right machine wall surfaces 5, there is formed an air passage 3c portion through which the sorting wind wrapped around from the left and right side portions 3b of the transfer shelf 3 blows out to the outside. Therefore, as shown in FIG. 4 and FIG.
The transfer shelf 3 is attached along the left and right sides 3b of the lower side surface 3a of the transfer shelf 3 along the left and right sides 3b to the left and right side walls 5a. The upper edge of 3b is slidably slidably contacted by the dustproof cover 1a. The grain stalks conveyed by the feed chain 10 of the threshing machine 7 are handled in the threshing chamber 8 by the handling cylinder 12 and the processing cylinder 1.
4, and the threshed after threshing is
Oscillating sorting shelf 1 leaking from handling network 15 and processing network 16
Fall on. Threshing straw chips that do not leak from the handling net 15 and the processing net 16 are sent out from the outlets of the nets 15 and 16 and discharged outside the machine by the dust fan 31. The thresh falling on the rocking sorting shelf 1 is sent to the chaff sheave 19 of the sorting section 23 by the transfer shelf 3, leaks from the chaff sheave 19 to the Glen Sheave 21, and further from the Glen Sheave 21. While dropping to the sorting shelf 22, the swinging transfer operation of the swing sorting shelf 1, the first sorting shelf 22 side from the Karamin 2 in the sorting air passage W and the Glen Sheave 2
Due to the blowing action of the sorting wind to the first side, the first selected grain flows down the first sorting shelf 22 and is housed in the first gutter 28 to be carried out of the machine. The thresh that does not leak from the chaff sheave 19 is sent to a straw rack 20, where the leaked material roughly selected by the straw rack 20 and the scattered matter from the first sorting unit 23 are separated by a second sorting shelf 24. During the dropping to the second sorting shelf 24, the second sorting is performed by the swinging transfer action of the swing sorting shelf 1 and the blowing action of the sorting wind from Karamin 2 in the sorting wind path W.
Flows down, is stored in the second gutter 30 and is returned to the processing cylinder 14. In addition, the sorting dust in the sorting air passage W and the straw waste from the straw rack 20 are discharged to the outside from the third port (dust discharging port). At the time of such a sorting operation, a gap A formed by the upper lip portion 17b upper surface 4a of the Karino discharge port 4 and the lower side surface 3a of the transfer shelf 3 of the swinging sorting shelf 1 is removed.
The lower end edge 6a of the rubber plate 6 attached to the upper lip portion 17b is slid over the entire upper surface 4a of the upper lip portion 17b so as to close the upper edge portion 4b. It is possible to prevent the sorting wind from circumventing 17b. Along with this blocking, the right and left sides 3 of the transfer shelf 3
The upper and lower portions of the gap B formed by the b and the left and right machine wall surfaces 5 are connected to the left and right side edges 6 of the left and right dustproof covers 1 a and the rubber plate 6.
b, the air path 3c is secured by blocking the air, and the selected air flowing to the left and right side portions 3b of the transfer shelf 3 is blown out from the air path 3c to the outside of the machine, thereby preventing the sorted air from flowing into the gap A. At the same time, the lower side 3a of the transfer shelf 3 and the
Since the accumulation of dust brought in by the sorting wind with the upper surface of the tray 7 can be prevented, unlike the related art, the swing sorting shelf 1 and the Karamin wind drum 17 are not damaged by the dust accumulation compression. . As another embodiment different from the above, as shown in FIG.
The distal end where the upper lip 17b is in contact with the upper lip 17b is opened to a narrow width to provide the auxiliary discharge port 32.
The wind piece 33 is made to protrude downward from the connection between the a and the Karamatsu wind drum 17. Kara-minoh 18 at the Karamin outlet 4
And the gap between the upper end of the upper lip 17b and the outer end of the upper lip 17b is b.
The gap between the wind section 33 and the wind section 33 is denoted by c, and the wind section 33 in the gap c is positioned on substantially the same circumference as the Karaoke wind tunnel 17, and the relation between the gaps a, b, and c is a>b> c. As a result, the separation wind discharged from above and below the wind split 26 of the Karino discharge port 4 causes the clearance between the lower side surface of the transfer shelf 3 of the swing sorting shelf 1 and the upper surface of the Karamine wind drum 17 from the upper lip 17b. However, at this time, the lower surface 3a of the transfer shelf 3 and the Karamin wind tunnel are separated by the sorted wind by being interrupted by the wall of the strong wind by the wind piece 33 discharged from the auxiliary discharge port 32 at this time. Since no dust is brought into the gap A between the top 17 and the top 17, it is possible to prevent the swing sorting shelf 1 and the Karamin wind drum 17 from being damaged due to the accumulation and compression of the dust. Further, as shown in FIG. 7, a wind selection unit clogging sensor 34 is fixed to the machine wall 5 at a triangular portion formed by the upper lip 17b and the upper surface 4a thereof.
The contact 34a of the sensor 34 is arranged in the space of the gap A formed by the lower surface 3a of the transfer shelf 3 of the swinging sorting shelf 1 and the upper surface 4a of the upper lip portion 17b, so that the first kernel has some sort of grain. When overflow occurs due to a factor and fills the sorting wind path W and reaches the gap A, the contact 3a of the sensor 34 is pressed by the pressure of the filled first kernel, and the sensor 34 is turned on. 7 is stopped, or an alarm is issued to notify the operator, so that the swing sorter 1
In addition, damage to the wind and wind drum 17 can be prevented.
