d. The lower part of the straw rack 3d is constituted by a second shelf 7a for guiding a second object into the second spiral 7, and the dust processing cylinder 25 extends to near the end of the second shelf 7a. It is a configuration that is out. The cross flow fan 8 is for discharging the light dust in the sorting chamber 30 to the outside of the machine, and is provided above the straw rack 3d.

In the combine equipped with the threshing device 4 configured as described above, power from an engine (not shown) is input to the traveling transmission 31 to drive the traveling device 14 by changing the speed to an arbitrary speed. . The combine then starts moving forward. In order to perform the cutting and threshing work, the work is further performed by transmitting the power from the engine to the cutting device 16, the supply and transport device 32, and the threshing device 4. When the combine moves forward in such a state, the planted cereal culm becomes the weeding tool 3
3 and the raising lug 3 of the raising case 34
5 caused. Thereafter, the stalks cut and cut by the cutting blade 36 are conveyed by the stock transfer device 37 toward the rear end of the supply and conveyance device 32.

Then, the cereal culm conveyed to the end of the stock carrier 37 is taken over by the starting end of the supply / conveying device 32 at the rear. Thereafter, the grain culm transported to the end portion of the supply transport device 32 is carried over to the starting end of the feed chain 17 of the threshing device 4, and the grain culm carried over by the feed chain 17 is transported rearward, Threshing is performed by the handling cylinder 1 and the handling net 22. A part of the threshed product falls onto the swing sorting shelf 3 and is sorted by the swinging operation of the swing sorting shelf 3 and by the wind sorting action from Karamin 5 and taken into the first spiral 6. I will go. The grains taken into the first spiral 6 are temporarily stored in a Glen tank 19, and the culms after threshing are discharged from the end of the feed chain 17 to the culm chains 3.
8 is taken over and transported. Then, it is sent to the cutter 39, cut, and discharged to the lower field.

The remaining thresh in the handling room 2 is transported rearward, and some of the thresh is taken into the second processing chamber 29 on the way. The thresh taken in the second processing chamber 29 is threshed by interaction between the second processing cylinder 27 and the second processing cylinder receiving gutter 28 while being conveyed to the upstream side in the sorting wind direction (particularly, branch spikes). The particles are processed) and fall on the swinging sorting shelf 3 below. The handling cylinder 1, the second processing cylinder 27, and the dust processing cylinder 25 are configured to rotate clockwise in a situation in which the downstream side is viewed from the sorting windward side (the front view of the threshing device 4). , Second processing cylinder 27
It is necessary to fix the direction of the processing teeth 27a in such a way that the thresh is sent in the upstream direction in the sorting wind feeding direction.

That is, the processing teeth 27a have the function of transporting the processing object to the upstream side in the sorting air feeding direction, and also have the function of processing the processing object. That is, processed tooth 2
Reference numeral 7a denotes a part of a spiral, which is configured to process an object to be processed by an interaction between a tip end in a circumferential direction of the spiral and the second processing cylinder receiving gutter 28. A blade 27b provided at the transport end of the second processing cylinder 27 forcibly sends out the object to be processed onto the swing sorting shelf 3.

The dust processing teeth 25b of the dust processing cylinder 25
Must be fixed in such a direction as to feed thresh to the lower side in the sorting wind direction. In the present embodiment, the dust processing teeth 25 b have a spiral shape wound around the outer peripheral surface of the dust processing cylinder 25.

However, in this embodiment, since the mesh of the dust treatment net 24 is rough (lattice-like), a part of the short straw waste falls on the swing sorting shelf 3 and the long straw which has not fallen is dropped. The debris is transported to the end of the dust processing chamber 26, and is forcibly discharged onto the straw rack 3d by the blade 40 at the end of the dust processing cylinder 25. And, in this way, the object to be treated is
While being conveyed in the inside 6, the interaction between the dust treatment cylinder 25 and the dust treatment net 24 causes further threshing, and the thresh is loosened and mixed with grains (so-called sari). The particles are taken out, fall on the swinging sorting shelf 3 below, and are further collected into the second spiral 7.

As described above, the thresh in the handling room 2 does not fall on the swing sorting shelf 3 and is not taken into the second processing chamber 29. It is transported to the end. The thresh carried to the end of the handling room 1 is taken into the dust treatment chamber 26, and the taken thresh is carried to the lower side in the sorting air feeding direction.

When the thresh is sent from the terminal end in the handling chamber 2 into the dust treatment chamber 26, the thresh is not clogged.
Also in the transfer part from the handling chamber 2 to the dust treatment chamber 26,
Spiral-shaped dust processing teeth 25b are provided on the outer periphery of the dust processing cylinder 25.
To prevent clogging of the transfer portion with threshing material due to the feeding action of the dust processing teeth 25b.

In spite of the above-mentioned swinging operation of the swinging sorting shelf 3 and the action of the sorting wind from Karino 5, the first spiral 6
The remaining kernels that have not been taken in are sent further back together with other dust and are taken into the second spiral 7. The second product taken into the second spiral 7 is returned to the lower side of the second processing chamber 29 in the sorting air feeding direction by the second fryer 41 and merges with the thresh from the handling chamber 2. Then, while being conveyed to the upstream side in the sorting wind direction, while being conveyed while being threshed by interaction with the second processing cylinder receiving gutter 28, the blade 27 b at the end portion moves to the lower swinging sorting shelf 3. It is forced to fall.

Next, FIG. 5 will be described. In the threshing device 4 that performs a series of operations as described above, the
The dust processing net 24 provided below the dust processing chamber 2
6 is provided detachably from the rear. This specific configuration is shown in FIG.

At both ends in the circumferential direction of the dust treatment net 24,
The screen frames 24a and 24b are provided. In addition, the dust treatment cylinder 2
The upper part of 5 is covered with a casing 9. At both ends of the casing 9 in the circumferential direction, recesses 9a and 9b with which mesh frames 24a and 24b of the dust removal processing net 24 can be engaged are formed, and the recesses 9a and 9b are provided in the recesses 9a and 9b. The mesh frames 24a and 24b of the dust treatment net 24 are engaged, and the dust treatment net 24
Are configured to be slidable in the longitudinal direction of the dust-discharge cylinder 25.

As a result, in the dust treatment chamber 26,
In the case where straw waste or the like is clogged, maintenance management can be easily performed by removing the dust treatment net 24 from the rear. Also,
As shown in FIG. 6, when the dust treatment net 24 is mounted, the stay 11 is fixed to the stay 11 provided on the threshing device 4 side with bolts 10 from behind. Therefore, the work of attaching and detaching the bolt 10 can be easily performed.

Next, FIG. 7 will be described. As described above, the second product is configured to be returned to the second processing chamber 29 from the second deep-frying cylinder 41. The diameter A of the cylinder 27 is configured to be larger than the diameter B of the second processing cylinder 27 in other portions. Thereby, the processing ability of the second product is improved. That is, since the processing effect is increased, the processing of the branch stalk is promoted, and the sorting performance of the first object is improved. Further, the second processing cylinder 27
In particular, when wet straw chips are conveyed, clogging is less likely to occur, and conveys smoothly.

Next, FIGS. 8 and 9 will be described. In this embodiment, the length of the second processing cylinder 27 in the longitudinal direction is reduced. That is, the position where the second product is returned from the second fried grain 41 is provided so as to be deviated to the upper side in the grain culm transport direction by the feed chain 17. Specifically, it is set to a position slightly forward of the intermediate portion of the handling cylinder 1. The grain processing cylinder 12 is formed from the rear end of the shortened second processing cylinder 27 to the start end of the dust processing cylinder 25. The feed direction of the second product of the shortened second processing cylinder 27 is configured to be fed from the lower side to the upper side in the grain stalk transport direction by the feed chain 17, and the feed direction of the processed object by the grain processing cylinder 12 is , Feed chain 1
7 is sent from the upper side to the lower side in the grain stalk transport direction.

The grain processing net 1 is located below the grain processing cylinder 12.
3 are provided to form a grain processing chamber 42.
Since the grain processing room 42 and the handling room 2 are partitioned by the handling net 22, only grains, branch stalks and other short straw chips enter into the grain processing room 42. These workpieces are processed by the processing rod 12b, and the processing teeth 1
While being processed in 2a, it is transported backward by the transport action of the processed tooth 12a. The object to be processed, which has been transported to the end of the grain processing chamber 42, falls on the swinging sorting shelf 3 below by the blades 12c.

Since the shortened second processing cylinder 27 and the grain processing cylinder 12 are partitioned by the partition plate 43, the second product is independently and efficiently processed, and the grain is processed. An object to be processed in the processing chamber 42 is also efficiently processed. Further, the shortened second processing cylinder 27 and the grain processing cylinder 12 are coaxial, and the rotation direction is configured to be opposite to that of the handling cylinder 1. As a result, the second material discharged from the second processing chamber 29 and the processed material discharged from the grain processing chamber 42 have, as shown in FIG. Since the objects fall down, the distribution of the objects to be processed on the swinging sorting shelf 3 can be prevented from becoming uneven. Since the end portion of the grain processing cylinder 12 and the start end portion of the dust processing cylinder 25 are separated by the partition plate 44, the object to be processed in the grain processing chamber 42 containing a relatively large amount of kernels, It is possible to prevent the objects to be processed in the dust processing chamber 26 having a relatively large amount of straw waste from being mixed, thereby preventing the sorting performance from being lowered.

Further, the configuration of the dust processing cylinder 25 is the same as the configuration described with reference to FIG. That is, the direction of rotation of the dust processing cylinder 25 is the same as that of the handling cylinder 1. The processing object is taken in from the terminal end of the handling room 2 and is processed while being transported rearward. Thereby, the intake of the object to be processed from the end portion of the handling chamber 2 into the dust treatment chamber 26 is improved. The remaining objects not to be taken into the dust treatment chamber 26 from the end of the handling chamber 2 are discharged to the discharge port 4 at the end of the handling chamber 2.
6 falls on the swing sorting shelf 3 below. A fin 45 that swings together with the swing sorting shelf 3 is provided in this falling portion. As a result, the workpiece falling from the discharge port 46 at the end of the handling chamber 2 is released by the swinging motion of the fins 45, so that the sari grains are collected and fall into the lower grain sheave 3b or the chaff sheave 3c. At this time, the action of the swinging movement of the swinging sorting shelf 3 and the action of the sorting wind from Karamin 5 further improve the grain sorting performance.

Next, FIG. 10 will be described. The threshing apparatus shown in FIG. 10 is a modification of the above-described threshing apparatus of FIG. The different point is that the position of the discharge port of the second fried grain cylinder 41 and the feed direction of the second product of the shortened second processing cylinder 27 are reversed. That is, the feed direction of the second product of the shortened second processing cylinder 27 is configured to be sent from the upper side to the lower side in the grain culm conveying direction by the feed chain 17. As a result, the material to be treated, which has a large amount of straw waste, which falls from the starting end of the handling room 2 to the starting end of the swing sorting shelf 3, and the second material, which falls from the second processing chamber 29, are mixed at a large ratio. Can be prevented. This is because most of the second articles in the second processing chamber 29 are transported backward.

Next, FIGS. 11 and 12 will be described.
In this configuration, only the second processing cylinder 27 is provided on one side of the handling cylinder 1. The feed direction of the second processing cylinder 27 is
In this configuration, the stalks are sent from the upper side to the lower side in the grain conveying direction. Therefore, the discharge port 41a of the second deep-frying cylinder 41
Is the starting end side of the second processing chamber 29. In addition, a continuous spiral 47 is provided on the outer periphery of the second processing cylinder 27, and is configured to process while transporting the second product backward. Further, the second processing chamber 29 and the handling chamber 2 are separated by a partition plate 48 in the longitudinal direction thereof. Waiting room 29
It is designed not to get inside. As a result, the processing efficiency of the second product in the second processing chamber 29 is improved, and the number of branch stalks is reduced.

Below the second processing chamber 29 is a second net 49.
, The second object falls onto the lower swing sorting shelf 3 while being conveyed rearward. Then, the processing object remaining up to the terminal end is configured to be discharged outside the machine. Further, the swing sorting shelf 3 has a configuration in which no straw rack is provided at the end portion. That is, behind the chaff sheave 3c, a space 50 is formed, and from the space 50, all the objects to be processed are taken into the lower second spiral 7. As a result, all the objects to be processed, which have been transported to the end of the chaff sheave 3c, are taken into the second spiral 7, except for light dust, and are then unhulled by the second hoisting cylinder 41, whereupon the second hoist It is sent to the starting end of the processing cylinder 27 and is processed again. As a result, the third loss is reduced and the number of branch stalks is also reduced, so that the first sorting performance is improved.

Next, FIG. 13 will be described. In the threshing apparatus shown in FIG. 13, the threshing apparatus described with reference to FIGS.
Side) is provided with a fan 51. The fan 51
Are arranged in parallel with the second processing cylinder 27, and the second processing cylinder 7
Is provided on the front side. The specific length is approximately
Is desirable, but may be longer or shorter.

The function of the fan 51 is to make the layer thickness of the object to be processed on the swing sorting shelf 3 uniform. In particular, in the configuration of the threshing apparatus shown in FIG.
Since no straw rack is provided at the end of the second processing chamber 27, the third object is also transported to the second processing cylinder 27 for processing. Is increased, and accordingly, the amount of the object to be dropped downward is also increased, so that the object to be processed on the swing sorting shelf 3 is prevented from being biased to one side.

As described above, since the fan 51 is provided on one side of the second processing cylinder 27, the thickness of the object to be processed on the swing sorting shelf 3 becomes uniform, and the sorting performance is also improved. become. As described above, the second processing cylinder 27 is provided on one side of the handling cylinder 1 so that only the second product is processed exclusively. Will be improved. Further, the second processing cylinder 27 has a length from the start end of the handling cylinder 1 to the end of the threshing device, and the processing stroke is lengthened, so that the processing efficiency is improved.
