Although it is one cross section, the processing object leaking from the handling cylinder receiving net 13 is configured to be taken into the second processing chamber 2b, so that the second processing cylinder 2a is removed from the inside of the handling chamber 1b that has joined the second processing chamber 2b. Are also processed together. Below the handling cylinder 1, the second processing cylinder 2a, and the dust processing cylinder 2c,
3 and a second processing drum receiving net 14 and a dust discharging drum receiving net 15 are provided.

Below the handling room 1b, the second processing room 2b, and the dust processing room 2d, there is provided a swinging shelf 16 for receiving and sorting the falling threshing material. Is provided at the start end side of the sorting air feeding direction below the
The first spiral 18 is provided on the lower side in the feed direction of the sorting wind blown from 7, and the second spiral 19 is provided on the lower side in the sorting wind sending direction of the first spiral 18.

The structure of the swing shelf 16 will be described. The swinging shelf 16 includes, in order from the starting end side in the sorting and feeding direction, a transfer shelf 16a for transferring dropped threshing material backward, a chaff sheave 16b for selecting threshing material, and a straw rack for transferring and discharging dust to the outside of the machine. 16c. The lower part of the straw rack 16c is constituted by a second shelf 19a for guiding a second object into the second spiral 19, and the dust treatment cylinder 2c extends to near the end of the second shelf 19a. It is a configuration that is out.

The casing fan 20 is for discharging the light dust in the sorting chamber 21 to the outside of the machine. Make up. In the combine equipped with the threshing device 3 configured as described above, power from an engine (not shown) is input to the traveling transmission device 22 to drive the traveling device 5 by changing the speed to an arbitrary speed. The combine then starts moving forward. In order to perform the harvesting and threshing work, power is further transmitted from the engine to the mowing device 7, the supply and transport device 23, and the threshing device 3 to perform the work. When the combine advances in such a state, the planted grain culm is weeded by the weeding tool 24 and raised.
5 is caused by the raising lug 25a. Thereafter, the stalks cut and cut by the cutting blade 26 are conveyed by the stock transfer device 27 toward the rear end of the supply transfer device 23.

The grain culm transported to the end of the stock transporter 27 is taken over by the start end of the feed transporter 23 at the rear. Thereafter, the grain culm transported to the end of the supply transport device 23 is carried over to the start end of the feed chain 8 of the threshing device 3, and the grain culm carried over by the feed chain 8 is transported rearward, Threshing is performed by the handling cylinder 1 and the handling cylinder receiving net 13. A part of the threshed threshed
It falls down and is selected by the rocking operation of the rocking shelf 16 and the wind selection action from the Karamin 17, and is taken into the spiral 18 most. The grains taken into the first helix 18 are temporarily stored in the Glen tank 10, and the culms after threshing are carried over from the end of the feed chain 8 to the beginning of the culm chain 28. Go. Then, it is sent to the cutter 29, cut, and discharged to the lower field.

The remaining thresh in the handling room 1b is transported rearward, and some of the thresh is taken into the second processing chamber 2b on the way. The thresh taken in the second processing chamber 2b is threshed by the operation of the second processing cylinder 2a and the processing cylinder receiving net 14 while being conveyed to the upper side in the sorting air feeding direction, and the lower swinging shelf 16 Falling up. The handling cylinder 1, the second processing cylinder 2 a, and the dust processing cylinder 2 c are all configured to rotate clockwise in a state where the lower processing side is viewed from the sorting windward side. Processing means 4
It is necessary to fix the direction of the thresh (hereinafter referred to as “processed tooth”) in such a direction that the thresh is sent in the upstream direction in the sorting air feed direction. The processing teeth 4 have an operation of transporting the object to be processed toward the upstream side in the sorting air feeding direction, and further have an operation of processing the object to be processed. That is, the processing tooth 4 is a part of a spiral, and its distal end in the circumferential direction and the second processing cylinder receiving net 1
4 is configured to process an object to be processed by an interaction between the object and the object. The dust processing teeth 2e of the dust processing cylinder 2c need to be fixed in such a direction as to feed the thresh to the lower side in the sorting wind feeding direction.

However, in the present embodiment, the dust receiving cylinder 1
Since the mesh of No. 5 is rough, some of the dust processing teeth 2e have no feeding action. As described above, the thresh in the handling room 1b, which does not fall on the swinging shelf 16 and is not taken into the second processing chamber 2b, is transported to the terminal end of the handling room 1b. Is done. The thresh conveyed to the end of the handling room 1b is taken into the dust treatment chamber 2d, and the thresh taken in is conveyed to the lower side in the sorting air feed direction while the thresh is in contact with the dust treatment cylinder 2c. Through the interaction of the dust-removing drum support net 15, 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 rack 16 below. Fall down.

When threshing is sent from the end of the handling chamber 1b into the dust treatment chamber 2d, a feeding spiral 31 is provided on the dust treatment cylinder 2c so as to prevent the threshing from being clogged. The feeding action prevents thresh from clogging. Such a rocking operation of the rocking shelf 16 and the
Despite the action of the sorting wind from, the remaining grains that were not taken into the spiral 18 most are sent further back together with other dust and are taken into the second spiral 19. . The second product taken into the second spiral 19 is
In the second lifted grain cylinder 30, it is reduced to the lower side of the second processing chamber 2 b in the sorting air feeding direction and merges with the threshing material from the handling room 1 b, and then transported to the upper side of the sorting air feeding direction. The threshing process is performed by the interaction with the second processing cylinder receiving net 14, and the falling thrust falls on the swinging shelf 16 below.

In a combine equipped with a threshing device 3 for performing such a series of operations, only the processing action of the processing teeth 4 provided on the second processing cylinder 2a cannot process the object to be processed, and Had a problem that was left. Therefore, as shown in FIG. 5, a processing means 4c (hereinafter, referred to as a processing rod) having no feeding action is provided between the processing teeth 4 provided on the second processing cylinder 2a.
The shape of the processing rod 4c is characterized by the second processing cylinder 2
It is a great feature that it bends A from the upper side to the lower side in the rotation direction of a. This is because the tip of the processing rod 4c is formed at an acute angle so that the grain is not damaged at this portion such as a shed. As a result, the processing action of the object to be processed in the second processing chamber 2b is improved, and the number of branch stalks is reduced and the sorting performance is improved. In the present embodiment, the processing rod 4c has a rod shape, but may have a polygonal shape. In short, any object can be used as long as the object can be processed.

Next, FIG. 6 will be described. This is an embodiment of another configuration of the second processing cylinder 2a. A continuous spiral 31 is provided on the outer peripheral surface of the second processing cylinder 2a. The continuous spiral 3
Providing 1 has not only a feeding action of the object to be processed, but also a processing action by an interaction between the leading end of the continuous spiral 31 and the second processing cylinder receiving net 14. The effect of the continuous spiral 31 is that the second processing chamber 2b is not clogged by a large feeding action even if a large amount of the workpiece is fed. However, since the feeding action is slightly large, the processing action of the workpiece is slightly inferior.

Therefore, as shown in FIG. 6, when the processing rod 4c having no feeding action as described above is provided, when the processing rod 4c acts on the workpiece, the feeding action is performed in the direction opposite to the continuous spiral 31. It is configured to be provided to give. Of course, the processing rod 4c itself has no feeding action,
If the processing rods 4c are continuously arranged, a slight feeding action occurs to the processing object. As a result, the object to be processed receives resistance, so that the continuous spiral 31 and the plurality of processing rods 4c are formed.
The interaction with the above makes it possible to give a processing action to the object to be processed, and therefore, it is possible to reduce the number of branch stalks, so that the sorting performance is improved.

Next, FIG. 7 will be described. As described above, the culm chain 28 takes over and conveys the culm conveyed to the terminal end of the feed chain 8 and conveys it toward the rear cutter 29. The culm chain 28 is provided with a tension 32 for stretching a chain 33. Conventionally, since the tension 32 was not provided, the chain 33 fluttered and generated noise, and the culm was easily clogged. Thus, by providing the tension 32, even if a load acts on or does not act on the chain 33, the chain 33 is always properly stretched, so that noise can be prevented without flapping. .

Although the tension 32 is always lifted upward by the spring 34 via the arm 35, any structure can be used as long as it can be lifted upward.
