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 device 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 terminal end of the stock transfer device 37 is taken over by the start end of the supply and conveyance device 31 at the rear. Thereafter, the grain culm transported to the terminal end of the supply transport device 31 is carried over to the start 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 a function of transporting the object to be processed to the upstream side in the sorting air feeding direction, and also have an effect of processing the object to be processed. 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 the present embodiment, since the mesh of the dust treatment net 24 is rough (lattice-like), some short straw wastes fall onto 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 threshing material in the handling room 2 which does not fall on the swing sorting shelf 3 and is not taken into the second processing room 29 is the remaining threshing material in the handling room 1. 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 threshing is sent from the terminal end in the handling room 2 into the dust treatment chamber 26, the threshing is prevented from being 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-described action of the swing operation of the swing sorting shelf 3 and the action of the sorting wind from the Karamin 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, FIGS. 5 to 7 will be described. As described above, when the harvesting operation is performed by the combine, if the threshing operation of wet handling continues, the object to be processed adheres to each portion in the threshing device 4. In particular, if it adheres to the swing sorting shelf 3, the sorting performance is reduced, and the swing sorting shelf 3 and its driving mechanism are damaged by the weight of the object containing water.

In view of the above, a heat generating means 46 (hereinafter, referred to as a heat generating device) is provided on the left side plate 44 and the right side plate 45 provided at both left and right end portions of the swing sorting shelf 3. Specifically, a plurality of heat generating devices 46 are provided at predetermined intervals. Thereby, the straw debris adhering to the swing sorting shelf 3 can be dried and removed, so that efficient work can be performed without interrupting the work for cleaning. Even if one or several pieces are damaged, the operation can be continued by the other heat generating devices 46. Further, since the heating device 46 itself is compact, maintenance of the heating device 46 can be easily performed. Further, since only necessary portions need to be heated, the electricity of the battery 48 can be used efficiently. The heat generating device 46 is of an electric heating type, and is configured to generate heat when a current flows from a battery 48. Since the battery 48 is constantly charged from the dynamo when the engine is operating, the battery 48 does not rise.

The heating device 46 generates a large amount of heat when the current value increases, and the amount of heat generated by the heating device 46 depends on the left and right side plates 4.
4,45 becomes reddish. However, if the left and right side plates 44, 45 generate heat so as to be redder, the attached straw wastes burn beyond the dry state, and the heat generated by the heating device 46 is such that the attached straw wastes are dried. It is desirable to drop it. As a result, the straw debris adhering to the oscillating sorting shelf 3 dries and falls downward, and is moved backward by the oscillating operation of the oscillating sorting shelf 3 and the action of the sorting wind from Karino 5. Is discharged from the rear part of the threshing device 4 to the outside of the machine.

Accordingly, it is possible to prevent the sorting performance from deteriorating and to prevent the swing sorting shelf 3 and its driving mechanism from being damaged. Further, since the swing sorting device 3 is made of iron, which is a metal, or stainless steel, which is an alloy, it has good heat conduction efficiency, and is therefore stretched over the left and right side plates 44, 45. Glen Sheave 3b or Chaff Sheave 3
Since heat is also conducted to c, the straw debris attached to the Glen Sheave 3b and the chaff Sheave 3c are also dried and fall downward. As a result, the objects to be processed on the swing sorting shelf 3 are efficiently sorted by the Glen Sheave 3b and the Chaff Sheave 3c.

The heating device 46 may be manually operated by a worker using a switch 49 provided on the operation section 18, or may be configured to be automatically operated. This automatic configuration will be described with reference to FIG. A moisture detecting means 47 (hereinafter, referred to as a moisture sensor) is provided at an arbitrary position in the threshing device 4, and when the moisture sensor 47 detects a moisture value equal to or more than a predetermined value, the heat generating device 46 is driven. The position where the moisture sensor 47 is provided may be any location as long as the moisture amount of the object can be detected. Moisture sensor 4
The specific configuration of 7 measures by irradiating an electromagnetic wave including a water absorption wavelength band. The wavelength absorbed by moisture is 1450
It is good to irradiate nm (nanometer). That is, when an object having a high moisture content is irradiated with the electromagnetic wave having the above wavelength, the moisture content becomes 1
Since the wavelength of 450 nm is absorbed, 1450 nm returned by reflection is measured. If the amount is small, the object to be treated contains a large amount of moisture.

As the installation position of the moisture sensor 47, specifically, above the transfer shelf 3a of the swing sorting shelf 3, near the first spiral 6, near the second spiral 7, the Glen tank 1
In 9, the upper part of the grain sheave 3b and chaff sheave 3c is good. The arrangement of the moisture sensor 47 is shown in FIGS. As described above, the heating device 46 can be automatically turned on and off so that the worker can efficiently continue the work without interrupting the mowing work for cleaning the swinging sorting shelf 3. Become.

Since a plurality of heat generating devices 46 are arranged on the swing sorting shelf 3, if the amount of heat generated by the heat generating device 46 is changed depending on the installation location of the heat generating device 46, the energy of the battery 48 can be efficiently reduced. It can be used. As a specific method, the area of the transfer shelf 3a of the swing sorting shelf 3 is large, and the area of the Glen sheave 3b and the chaff sheave 3c is small.
If the detected values of moisture by the same are the same moisture value, the transfer shelf 3a
Generates more heat. Basically, it is preferable to increase the difference in the amount of heat by converting the difference in the area by the ratio. Similarly, if the moisture value obtained by the moisture sensor 47 is the same, the amount of heat generated by the heating device 46 may be changed depending on the amount of the object to be processed.

As another embodiment, the amount of heat generated by the heating device 46 may be changed depending on the difference between the detection values of the moisture sensor 47. This makes it possible to efficiently remove an object to be processed attached to the swing sorting shelf 3 and efficiently use the electric energy of the battery 48.

As described above, according to the present invention, a plurality of heat generating means 46 are provided on both left and right sides of the swing sorting shelf 3 at predetermined intervals.
The straw debris adhering to the swing sorting shelf 3 can be dried and removed, and efficient work can be performed without interrupting the work for cleaning. And even if one or several are damaged,
The operation can be continued by another heating means 46. Also,
Since the heat generating means 46 itself is compact, maintenance of the heat generating means 46 can be easily performed. Furthermore, since only necessary portions need to be heated, energy can be used efficiently.

According to the second aspect of the present invention, when the moisture value detecting means 47 detects a moisture value equal to or more than a predetermined value, the control means 100 for turning on the heat generating means 46 is provided. The work can be efficiently continued without interrupting the mowing work for the cleaning work of the swing sorting shelf 3.
