Below the swing shelf 9, A Karamin 10 is provided at the start end of the sorting wind, and a spiral 11 is provided on the lower side in the feeding direction of the sorting wind blown from the Karin 10; A spiral number 12 is provided.
[0010]
The configuration of the swing shelf 9 will be described. The swinging shelf 9 includes, in order from the starting end side in the sorting and feeding direction, a transfer shelf 9a for transferring dropped threshing material backward, a chaff sheave 9b for selecting threshing material, and a straw rack for transferring and discharging dust to the outside of the machine. 9c. Below the straw rack 9c, a second shelf 12a for guiding a second object into the second spiral 12 is formed, and the dust discharge processing cylinder 7 extends to near the end of the second shelf 12a. Is out.
[0011]
The cross flow fan 33 is for discharging light dust in the sorting chamber 34 to the outside of the machine, and is configured above the straw rack 9c. In the combine equipped with the threshing device 1 configured as described above, power from an engine (not shown) is input to the traveling transmission 24, and the traveling device 16 is driven by shifting the speed to an arbitrary speed. The combine then starts moving forward. In order to perform the harvesting and threshing work, the power is further transmitted from the engine to the reaper 18, the supply / transportation device 19, and the threshing device 1 to perform the work. When the combine moves forward in such a state, the planted cereal culm is weeded by the weeding tool 20 and raised by the raising case 21. Thereafter, the stalks that have been cut and cut by the cutting blade 22 are conveyed by the stock transfer device 23 toward the rear end of the supply and transfer device 19.
[0012]
The grain culm transported to the terminal end of the stock transport device 23 is taken over by the start end of the feed transport device 19 at the rear. Thereafter, the grain culm transported to the terminal end of the supply transport device 19 is carried over to the start end of the feed chain 3 of the threshing device 1, and the grain culm carried over by the feed chain 3 is transported rearward, Threshing is performed by the handling cylinder 4 and the handling cylinder receiving net 30. A part of the threshed after threshing falls on the rocking shelf 9 and is selected by the rocking operation of the rocking shelf 9 and the wind selection action from the Karamin 10, and is taken into the first spiral 11. Go. The grains taken into the first spiral 11 are temporarily stored in a Glen tank 26, and the culms after threshing are carried over from the end of the feed chain 3 to the beginning of a culm chain 27. Then, it is sent to the cutter 28 where it is cut and diffused by the lower diffuser 29 to be uniformly discharged to the field scene.
[0013]
The remaining thresh in the handling room 2 is transported rearward, and some of the thresh is taken into the processing chamber 6 on the way. The thresh taken in the processing chamber 6 is threshed by the action of the processing cylinder 5 and the processing cylinder receiving net 31 while being conveyed to the upstream side in the sorting wind direction, and falls onto the swinging rack 9 below. To go. All of the handling cylinder 4, the processing cylinder 5, and the dust processing cylinder 7 are configured to rotate clockwise in the front view of FIGS. 5 and 6 (when viewed from the sorting windward side to the downstream side). The direction of the processing teeth 5a of the body 5 needs to be fixed in such a manner that the thresh is sent in the upstream direction in the sorting wind feeding direction. Further, the dust-extraction teeth 7a of the dust-exhaust cylinder 7 need to be fixed in such a direction as to feed the thresh to the lower side in the sorting air feeding direction. FIG. 5 is an S1-S1 cross section of the threshing apparatus 1, and FIG. 6 is a S2-S2 cross section of the threshing apparatus 1.
[0014]
As described above, the remaining thresh that has not fallen on the swinging shelf 9 due to threshing in the handling room 2 and has not been taken into the processing chamber 6 is transported to the terminal end of the handling room 2. . The thresh conveyed to the end of the handling room 2 is taken into the dust treatment chamber 8, and the thresh taken in is conveyed to the lower side in the sorting air feeding direction, while being conveyed to the dust treatment cylinder 7. By the interaction of the dust-removing drum support net 32, the threshing is further released, and the threshing is loosened to take out the grains (so-called sari grains) mixed therein, and put on the swinging shelf 9 below. Fall down.
[0015]
Despite the action of the rocking movement of the rocking shelf 9 and the action of the sorting wind from the Karamin 10, the remaining kernels that were not taken into the spiral 11 most are sent further back together with other dust. It is taken into the second spiral 12. The second product taken into the second spiral 12 is returned to the lower side of the sorting air feeding direction of the processing chamber 6 by the second fryer 35 and merges with the threshing material from the handling chamber 2, Thereafter, while being conveyed to the upstream side in the sorting wind direction, threshing is performed by the interaction with the processing drum receiving net 31 and falls onto the swinging shelf 9 below.
[0016]
In the combine equipped with the threshing device 1 that performs such a series of operations, the processing cylinder 5 and the dust processing cylinder 7 are formed of a coaxial core of the shaft 14, and the dust processing cylinder 7 is A cylindrical body 15 for constituting is provided. The processing cylinder 5 has a processing tooth 5a implanted in the front part of the shaft 14, and the processing tooth 5a transfers the thresh in the processing chamber 6 to the upstream side in the direction of the sorting wind by the Karamin 10. It is implanted on the shaft 14. Further, the dust processing teeth 7a are planted in the cylindrical body 15 so as to transfer the thresh in the dust processing chamber 8 to the lower side in the direction of the sorting wind by the Karin 10. The cylindrical body 15 is fixed to the shaft 14, and is formed by a flange portion 15a and an outer peripheral portion 15b.
[0017]
As described above, since the processing cylinder 5 and the dust processing cylinder 7 are configured, there is no need to transmit each of them by a separate drive system, and the configuration is simplified accordingly. Further, the dust processing teeth 7a of the dust processing cylinder 7 are fixedly provided on the outer peripheral portion 15b of the cylindrical body 15, and therefore, since the space between the shaft 14 and the cylindrical body 15 is a space, the weight is reduced by that much. Be converted to Next, the handling cylinder receiving network 30 and the processing cylinder receiving network 31 shown in FIG. 5 will be described.
[0018]
At the contact point 36 with the processing cylinder receiving net 31, the handling cylinder receiving net 30 is divided into an upper treating cylinder receiving net 30a and a lower treating cylinder receiving net 30b. Here, in forming the mesh of the upper handling cylinder receiving net 30a and the mesh of the processing cylinder receiving net 31, the mesh of the processing cylinder receiving net 31 is more than the mesh of the upper handling cylinder receiving net 30a. Is made larger. This makes it easy for the thresh in the processing chamber 6 to fall on the swinging rack 9 below, so that the thresh in the processing chamber 6 is not persistently threshed. As a result, an excessive load is not applied to the paddy, so that the so-called detaching phenomenon, in which the portion of the paddy skin peels off, can be prevented.
[0019]
Also, as a different way of thinking from the mesh of the above-described net, the mesh of the processing cylinder receiving net 31 is made smaller than the mesh of the upper handling cylinder receiving net 30a. As described above, some of the thresh in the handling room 2 leaks from the upper handle receiving net 30a and enters the processing chamber 6, but even in the same state of threshing, It easily leaks from the net 30a and hardly leaks from the processing cylinder receiving net 31. Therefore, the branch stalk remaining without being threshed in the handling room 2 is sufficiently threshed again in the processing chamber 6, and the branch stalk becomes a normal kernel. In particular, since the lower spiral 11 is located below the processing chamber 6, it is possible to prevent the branch stalks from directly entering the Glen tank 26 and being harvested.
[0020]
【The invention's effect】
According to the present invention, as described above, the processing cylinder 5 and the dust processing cylinder 7 are configured by the shaft 14 having a coaxial core, and the processing teeth 5a of the processing cylinder 5 are configured by being implanted at the front portion of the shaft 14. Since the dust processing teeth 7a of the processing cylinder 7 are fixed to the outer peripheral portion 15b of the cylindrical body 15 fixed to the shaft 14, it is necessary to transmit the processing cylinder 5 and the dust processing cylinder 7 by separate drive systems. Therefore, the configuration is simplified and the weight is reduced. In addition, since the space between the shaft 14 and the cylindrical body 15 is a space, the weight is reduced accordingly. The handle cylinder receiving net 30 is divided into an upper handle cylinder receiving network 30a and a lower handle cylinder receiving network 30b at a contact point 36 with the processing cylinder receiving network 31. Since the structure of the processing cylinder receiving net 31 is configured to be larger than the structure, thresh in the processing chamber 6 is more likely to fall on the swinging rack 9 below, and thresh in the processing chamber 6 is persistent. No more threshing. As a result, an excessive load is not applied to the paddy, so that the so-called detachment phenomenon that the pad portion of the paddy peels can be prevented.
