When the operation state detecting means detects that the harvesting operation is being performed while the operation state is being switched to the operating state, the target selection state is determined based on information from the processing amount detection means and the target selection state adjusting means. Zu Activate the sorting control for the harvesting work to be automatically adjusted, and when it is detected that the harvesting work state is not detected by the work state detecting means while the operation state is being switched to the operating state, a preset target sorting state is set. The present invention relates to a combine sorting control device configured to activate a sorting control for a non-cutting work that is automatically adjusted.

[Conventional technology]

In this type of combine sorting control device, even if the amount of processing by the threshing device during the harvesting operation is the same, if the type of grain rods or the growing condition is different, the appropriate target sorting condition will differ. Will occur.

Therefore, the target sorting state is automatically determined by selectively using two types of sorting control, that is, a processing amount detecting means, a target sorting state adjusting means, a work state detecting means, and a sorting control for a cutting operation and a sorting control for a non-cutting operation. Sorting control means for adjusting, and a manually operated switching means for switching the sorting control means between an operating state and a non-operating state of the sorting control are provided, and the sorting control means is switched to an operating state of the sorting control, Further, when the work state detecting means detects that the harvesting work state is in effect, and the target selection state is changed and adjusted while the selection control means is in the activated state of the selection control for the harvesting work, the change adjustment is performed. The target sorting state is automatically adjusted based on information from the processing amount detection means.

[Problems to be solved by the invention]

However, the sorting control means automatically adjusts the target sorting state in the sorting control for the reaping work based on the information of the processed material amount detecting means and the target sorting state adjusting means, and is preset in the sorting control for the non-cutting work. It is configured to automatically adjust to the target selection state, so that when the selection control means is switched to the non-operation state, or when the selection control means is switched to the operation state, the selection control for non-reaping work is performed. Even if the target selection state is changed and adjusted when the is activated, the selection control means does not automatically adjust the changed target selection state based on the information of the processing amount detection means, and the selection state does not change. At the time of inspection, etc.

The present invention has been made in view of the above circumstances,
The purpose is that, when the target selection state of the selection device is changed by the target selection state adjustment means, it is possible to accurately confirm whether or not the selection state of the selection device is changed in conjunction with the change, and the selection control means It is an object of the present invention to prevent erroneous recognition of a failure when the device is switched to a non-operating state or during inspection when the harvesting operation is not performed.

[Means for solving the problem]

In the combine sorting control device according to the present invention, a sorting device that sorts and treats the leaked material from the handling room is provided so as to be adjustable in a sorting state according to the amount of the handled material, and the amount of the leaked material from the handling room is adjusted. , A target selection state adjusting means for changing and adjusting a target selection state for the same processing amount, a work state detection means for detecting whether or not a cutting operation state is present, and a target selection of the selection apparatus. Sorting control means for adjusting the state, and manually operated switching means for switching the sorting control means between an operating state and a non-operating state of the sorting control are provided, and the sorting control means is switched to the operating state. When the harvesting work state is detected by the work state detecting means while the target is in operation, the target sorting state is automatically adjusted based on information of the processed material amount detecting means and the target sorting state adjusting means. When the operating state is detected by the operating state detecting means while the operating state is being switched to the harvesting state, the sorting operation is automatically adjusted to a preset target selecting state. A combine sorting control device configured to start sorting control for non-reaping work, the characteristic configuration of which is a display unit that displays whether the sorting control unit is in the operating state, There is provided a display means for displaying whether the sorting control means is in the activated state of the sorting control for the reaping work or in the activated state of the sorting control for the non-cutting work.

(Operation)

That is, an indication that the sorting control means is in the operating state,
When the sorting control means changes and adjusts the target sorting state of the sorting device by the target sorting state adjusting means by displaying that the sorting control means is in the activated state of the sorting control for the mowing work, the sorting state corresponds to the changed target sorting state. The state of the sorting control means is inactive, and the indication that the sorting control means is in the inactive state and the indication that the sorting control means is in the activated state of the sorting control for non-cutting work are displayed by the target sorting state adjusting means. It can be seen that even if the target selection state of the selection device is changed and adjusted, the selection state does not change in accordance with the changed and adjusted target selection state.

〔The invention's effect〕

Therefore, when the target selection state of the selection device is changed by the target selection state adjusting means, it is possible to accurately confirm whether or not the selection state of the selection apparatus changes, and the selection control means is switched to the non-operation state. This can prevent erroneous recognition as a failure at the time of inspection or when the harvesting operation is not performed.

If the sorting state of the sorting apparatus does not change even after the target sorting state of the sorting apparatus is changed and adjusted, it may be because the sorting control means is not in the operating state, or the sorting control means is not used for sorting. It is possible to determine whether it is caused by the control being activated or by both of them, and it is possible to appropriately perform the necessary operations thereafter.

〔Example〕

Hereinafter, an embodiment in the case where the present invention is applied to a sorting control device for an all-rods combine type combiner will be described with reference to the drawings.

As shown in FIG. 9, the all-rods-type combine combines an airframe (V) equipped with a crawler traveling device (1), a boarding operation unit (2), and a threshing device (3), and an airframe at the front thereof. A cutting pre-processing unit (4) mounted so as to be able to drive up and down around a horizontal axis centered in the width direction.

The cutting pre-processing unit (4) includes a weeding tool (5) provided at the tip thereof, a reel (6) for scraping the planted grain stick to the rear side of the body (V), and a scraped grain stick. Clipper-type cutting blade (7) for cutting the base of the sword, an auger (8) for receiving the cutting stick and sending it to the rear of the machine body (V), and a scraping-up transport unit having three rotating drums arranged side by side (9).

The threshing device (3) is provided for a handling room (A) into which all of the cutting sticks transported by the scraping and transporting unit (9) are thrown, and for a processed material leaking from the handling room (A). (B) equipped with an oscillating sorting plate (10) that performs sorting
And Karamin (11), which blows the sorting wind.

In the handling room (A), a handling cylinder (1) having a rotation axis that is inclined in a rearward direction along the front-rear direction of the body (V).
2) is provided, and below the handling cylinder (12), a receiving net (13) for leaking threshing products is provided over substantially the entire length of the handling chamber (A) in the front-rear direction.

Then, as shown in FIGS. 9 and 10, the ceiling cover (14) at the grain rod entrance side portion of the handling chamber (A) determines whether or not the handling chamber (A) is in the grain rod supply state. A contact-type stick detection sensor (S ₀ ) is installed as a stick supply state means for detecting the stick.

If the explanation of the grain stick detection sensor (S ₀ ) is added,
A contact piece (15) swingably mounted around an axis parallel to a rotation axis of the handling cylinder (12) so as to contact a workpiece in the handling chamber (A); A spring (16) for biasing (15) to a side contacting the handling cylinder (12);
A switch (17) that is turned on as the contact piece (15) swings over a set value. That is, when a grain rod is supplied to the handling chamber (A), the contact piece (15) comes into contact with a workpiece to be handled and processed by the handling cylinder (12), and the switch (17) is turned on. When the supply of the rod is stopped, there is no processed material in contact with the switch (17), so that the switch (17) is turned off. The switch (1
When 7) is turned on, it is detected that the rod is being supplied, and when it is turned off, it can be detected that the rod is not being supplied. However, although not described in detail, the switch (17) continues to be set for a set time (set to 2 seconds) for a set time (set to 2 seconds) because a grain stick comes into contact with the contact piece (15) intermittently.
When in the OFF state, the rod is determined to be in the non-supply state.

As shown in FIG. 10, the rocking sorter plate (10) is arranged so as to line up sequentially from the front to the rear, with the Glen pan (18) and the chaff sheave (19), and below the chaff sheave (19). , Each of which is fixed between a pair of left and right side plates (21), and is formed in a plate shape as a whole.

In the lower part of the sorting device (B), a first-part collecting section (22) for collecting the grains leaking from the Glen Sheave (20) as the first, a terminal end of the chaff sheave (19) and the Glen Sheave A second product recovery unit (23) is provided for recovering a processed product (abbreviated as a second product in the following description) mixed with straw chips and the like that fall over the terminal end of (20). ing. Although not described in detail, the second collection part (2
The second product recovered from 3) is returned to the handling room (A) and handled again.

As shown in FIG. 11, the chaff sheave (19) is composed of a plurality of strip-shaped members (19a) juxtaposed in the processing object transfer direction (left-right direction in the figure), with the upper end serving as a fulcrum. The operating rod (24), which is rotatably attached to the side plate (21) of which the lower end of each band-shaped member (19a) is pivotally attached, is pushed and pulled in the front-rear direction, whereby the band The space (t) (which may be abbreviated as a chaff opening in the following description) between the shape members (19a) can be changed and adjusted.

An electric motor (M ₁ ) is provided as an actuator for changing the opening degree of the chaff, and a link mechanism (25) driven by the electric motor (M ₁ ) and the operating rod (24) are connected by a release wire (26). Linked and linked. In the figure, (27) is spring urges return to side closing said chaff opening, as chaff opening the operation amount of the (S ₂₎ is the operating rod by the electric motor (M ₁₎ (24) A potentiometer-type chaff opening detection sensor for detection, which is attached to the link mechanism (25).

As for the Karino (11), a so-called split pulley type continuously variable transmission is used, and the air flow rate can be changed and adjusted by changing the rotation speed.

To add an explanation, as shown in FIG.
An input pulley (28) for rotating and driving 1) is configured as a split pulley, and an operation arm (29) for changing the diameter of the input pulley (28) is rotated by an electric motor (M ₂ ) as an actuator for adjusting the air volume of the toy. It is provided to be operated dynamically. Thus, by changing and adjusting the rotation speed of the Karamin (11) to high or low by the electric motor (M ₂ ), the blown air amount (which may be abbreviated as tomomi air amount in the following description) can be changed and adjusted to be strong or weak. Has become. In the figure, (30) the electric motor (M ₂₎ linkage mechanism driven by (32) and said operation arm (29) and the interlocking connection to the release wire, (S ₃₎ is the operating arm (29 ) Is a potentiometer-type toy air flow detection sensor that detects the operation amount as a toy air flow, and is attached to the linkage mechanism (32).

In other words, the sorting device (B) adjusts the opening degree of the chaff to large and small, and adjusts the air volume of the turtle to a high level and a low level to sort the leaked material from the handling chamber (A) according to the size. It is configured so that the condition can be adjusted. In addition, as will be described in detail later, basically, the leak amount from the handling chamber (A) is increased such that the larger the amount of the processed material, the larger the chaff opening degree and the stronger the storm air flow. The sorting state is automatically adjusted according to the amount of processed material.

Next, a control configuration for automatically adjusting the sorting state of the sorting device (B) will be described.

As shown in FIG. 1, a control device (33) using a microcomputer is provided, and the control device (33) is provided with a control device based on a grain stick detection sensor (S ₀ ) and a driving speed of a crawler traveling device (1). Speed sensor (S ₁ ) to detect vehicle speed, chaff opening degree detection sensor (S ₂ ), toumi air volume detection sensor (S ₃ ),
A chaff opening degree setting device (S ₄ ) for changing and adjusting a target chaff opening degree for the same processing amount, a tofu air amount setting device (S ₅ ) for changing and adjusting a target torsion air amount for the same processing amount, and a threshing device (3) each of the threshing clutch operating permitting and blocking the driving force transmission threshing switch for detecting whether the state cut or is in a state (not shown) enters (S ₆₎ is connected for. In other words, the chaff opening degree setting device (S ₄ ) and the tomato air volume setting device (S ₅ ) correspond to the target selection state adjusting means for changing and adjusting the target selection state for the same amount of processed material. However, the tomami air volume is set as the value of the rotation speed of the Karamin (11).

In the drawing, (SW ₁ ) is an automatic mode for automatically adjusting the chaff opening and the storm flow according to the amount of the leaked material, and the setting unit (S ₄ ) for the chaff opening and the storm flow. , (S ₅ ), an automatic switch for selecting a manual mode to maintain the target value set by (S ₅ ), (S ₅
W ₂ ) indicates that the type of grain rod supplied to the handling room (A) is rice,
A grain rod type indicating switch for indicating whether it is wheat or soybean, (34) is a bar graph type display for displaying the current value of the chaff opening and the turtle air volume, and (35) is the manual mode selection. wherein each setting device (S _4), the alarm device to alarm activation that incorrect setting of the target value by (S ₅₎ at the time,
(36) is an auto lamp which is lit and displayed when the automatic mode is selected, and (37) is a control state display lamp as a display means which illuminates and indicates that the selection state of the selection device (B) is in a controllable state where the selection state can be automatically adjusted. It is.

Then, using the control device (33), the processing amount detection means (100) for detecting the amount of material leaking from the handling room (A), and the selection state of the selection device (B) can be automatically adjusted. Determining means (10) for determining whether or not control is possible;
1) When the determination means (101) determines that the controllable state is established, the target selection state is determined by the chaff as the processing amount detection means (100) and the target selection state adjustment means. is the respective opening setter (S ₄₎ and winnowing fan air volume setter sorting device based on the information of the (S ₅₎ sorting control means for automatically adjusting the selection state of (B) (102) is configured . Therefore, the automatic switch (SW ₁ ) is configured as a manually operated switching means for switching the selection control means (102) between the operation state and the non-operation state of the selection control, and the automatic lamp (36) is provided with the selection control means ( 102) is configured as a display means for displaying whether or not it is in the operating state.

 Next, each means will be described.

If the processing amount detection means (100) is described,
As the vehicle speed of the combine increases, the supply amount of grain rods to the handling room (A) increases, and as a result, the amount of material leaked from the handling room (A) increases. That is, the amount of material that has leaked from the handling room (A) increases or decreases in proportion to the vehicle speed. Therefore, in the present embodiment, the chaff opening degree and the wind volume
By correcting according to the value of the vehicle speed detected by the vehicle speed sensor (S ₁ ) with reference to the target value set by the chaff opening degree setting device (S ₄ ) and the tongue air volume setting device (S ₅ ) The sorting state of the sorting device (B) is automatically adjusted to the sorting state according to the amount of material leaked from the handling room (A).

The target value set by the setting devices (S ₄ ) and (S ₅ ) will be described. As shown in FIG. 3, the target value of the chaff opening degree is determined by setting the chaff opening degree setting device (S ₄ ). When operated to the minimum value, it becomes a value corresponding to the state of slightly opening from the fully closed state, and the maximum value of the chaff opening degree setting device (S ₄ ) corresponds to the maximum value of the adjustable chaff opening degree. , The adjustment range is set. As shown in FIG. 4, the maximum value of the toy air volume setting device (S ₅ ) is the minimum rotation speed (800 rpm) and the maximum value is the maximum rotation speed (1250 rpm). Thus, the adjustment range is set.

However, the threshing chamber when Koku桿supplied to (A) is a wheat and soybeans, the winnowing fan air volume the winnowing fan air volume setter regardless Moshita processing amount (S ₅₎ set by the target value Is maintained. In addition, when the grain is made of wheat, the chaff opening degree setting device (S ₄ ) adjusts the chaff opening degree to the closing side as the vehicle speed decreases, as shown in FIG. The upper limit of the target value is automatically adjusted according to the vehicle speed, and the air flow rate is set by the air flow rate setting device (S ₅ ) in the range of 1000 rpm to 1200 rpm as shown in FIG. The target value is maintained.

When the cereal rod is rice, the chaff opening is automatically adjusted according to the vehicle speed, as in the case of wheat, as shown in FIG. The winnowing fan air volume, as shown in FIG. 8, it is constituted such that it is automatically adjusted the winnowing fan air volume setter as the vehicle speed becomes larger the more strong side target value set by the (S ₅₎ as the lower limit. However, at the same vehicle speed, the chaff opening degree is adjusted to be closer to the closing side than wheat.

When the grain rod is soybean, although not shown, both the chaff opening and the turtle air volume are determined by the setting device (S ₄ ),
It is so as to maintain the target value set by the (S _5).

Next, determining means (10) for determining whether or not the sorting state of the sorting apparatus (B) is in a controllable state in which the sorting state can be automatically adjusted.
1) will be described.

Whether the type of grain rod is rice, wheat, or soy,
If the threshing device (3) is not in operation, the sorting process cannot be performed. Similarly, since the tow air volume is adjusted by a split pulley type transmission, power cannot be adjusted unless power is transmitted and Karino (11) is not rotating. If the automatic mode is not selected, the automatic adjustment of the sorting state is not performed. Furthermore,
In a state where no grain rod is supplied to the handling room (A), the sorting state cannot be automatically adjusted.

Therefore, there is a threshing switch (S ₆₎ of the threshing device ON (3) is operational, is in the automatic mode selection state auto switch (SW ₁₎ is in ON, winnowing fan (11) is set rotational speed (500 rpm)
In the state where the rotator is driven to rotate, and when the type of the grain rod is rice or wheat, the controllable state is provided on condition that the handling chamber (A) is in a state where the grain rod is supplied. Is determined. However, in the case of soybeans, the setter sorting state (S _4), since it is so as to maintain the target value by (S _5), Koku桿the threshing chamber (A) is supplied That is, whether or not the vehicle is in the control state is not included in the condition for determining whether or not the vehicle is in the controllable state.

Incidentally, whether it is in a state where the winnowing fan (11) is rotated at a set rotation speed (500 rpm) or more, it will be determined based on the information of the winnowing fan air amount detecting sensor (S _3), and Whether or not the handling rod (A) is being supplied with the pestle is determined based on the information of the pestle detection sensor (S ₀ ).

Incidentally, the sorting control means (102) automatically adjusts the sorting state of the sorting device (B) in accordance with the type of grain rod to be threshed, in accordance with the amount of material that has been leaked from the handling room (A). Become. Therefore, if the sorting device (B) is not in a controllable state, the chaff opening degree and the toumi air volume do not change even if the chaff opening degree setting device (S ₄ ) and the toy air volume setting device (S ₅ ) are operated. May be mistaken for a failure.

Therefore, based on the information of the determination means (101), whether or not the selection control means (102) is in a controllable state is displayed by turning on / off the control state display lamp (37). It is.

The description of the selection control means (102) will be added.
When the automatic mode is selected, a first control state in which the amount of air blown by the Karin (11) is automatically adjusted in accordance with the amount of the material to be leaked from the handling room (A) in accordance with the type of grain rod to be threshed; It is configured to be freely switchable to a second control state in which the set value is maintained. However, the first control state and the second control state
In any of the control states, the opening degree of the chaff is automatically adjusted according to the amount of the leaked material.

By the way, since there is no leaked material from the handling room (A) until the mowing operation is started, the sorting state cannot be automatically adjusted according to the vehicle speed, so that the chaff opening is maintained at a preset minimum value. In addition, the air volume of the turtle is maintained in the weakest state. Note that the control state up to the start of the mowing operation is abbreviated as mode 1 in the following description. However, the minimum value of the chaff opening degree in the mode 1 is set so that rice is more open than wheat.

After the mowing operation is started, as described above, the chaff opening degree and the wind volume are automatically adjusted based on the information from the vehicle speed sensor (S ₁ ) so as to be in a sorting state in accordance with the amount of leaked material. Become. However, in the case of wheat and soybeans, the turtle air volume is maintained at the set target value. The control state during the mowing operation is abbreviated as mode 2 in the following description. That is, the control state of mode 2 corresponds to the state in which the determination means (101) determines that the selection state (B) is in the controllable state.

Next, when the mowing operation is completed, the state returns to the state (mode 1) before the mowing operation is started. However, even after the mowing operation is completed, the processed material remains in the handling room (A) for a while. Therefore, the leakage of the processed material to the sorting state (B) does not stop immediately, but gradually decreases with time. Therefore, after the mowing operation is completed, the current chaff opening and the tomami air volume are maintained until the set time elapses, and then the mode 1 is changed to the mode 1 while gradually decreasing the chaff opening and the tomami air volume to a weak level. It is made to shift. The control state at the end of mowing is abbreviated as mode 3 in the following description.

However, when the grain type indicated by the grain type indicator switch (SW ₂ ) is wheat, only the chaff opening is automatically adjusted, and the turtle air volume is the target set by the turtle air volume setting device (S ₅ ). Value will be maintained. In the case of soybeans, both the chaff opening degree and the turtle air volume are maintained at the set target values. Note that the time for maintaining the chaff opening at the current value is such that the rice is longer than the wheat and the minimum value when returning to the mode 1 is:
Rice is larger than wheat. In the case of rice, when the mode is shifted from the mode 3 to the mode 1, the air volume of the turtle is decreased stepwise.

The start of cutting and the end of cutting are determined based on the information of the grain stick detection sensor (S ₀ ).

Next, the operation of the control device (33) will be described based on the flowchart shown in FIG.

As the control is activated, the automatic switch (S
It is determined whether or not the automatic mode is selected based on information of the W _1).

When the automatic mode is selected, the control means determines whether or not the state is controllable by the determination means (101). If the control mode is enabled, the control state display lamp (37) is turned on to enable control. If not, the control status indicator lamp (37) is turned off.

Next, based on the information of the grain stick detection sensor (S ₀ ),
It is determined whether the cutting is in progress, during cutting, or after cutting.

When the stick detection sensor (S ₀ ) is OFF and the stick is not supplied, it is determined that the stick is in a state before the start of cutting, and the mode shifts to the mode 1 control state.

When the stick detection sensor (S ₀ ) is ON and in the stick supply state, it is determined based on the ON / OFF change direction whether cutting is in progress or the transition from cutting to end of cutting is being performed.

That is, when the grain stick detection sensor (S ₀ ) changes from OFF to ON to determine the start of cutting, the state shifts to the control state of mode 2 for cutting and automatically adjusts the sorting state. When the cutting stick detection sensor (S ₀ ) changes from ON to OFF to determine the end of cutting, the mode shifts to cutting end mode 3.

Therefore, the sorting control means (102) uses the grain stick detection sensor (S
If _{the 0)} is in Koku桿supply state ON, the processing target selection state quantity detecting means (100) and the target selection condition adjusting means (S _4), reaper automatically adjusted based on the information of (S ₅₎ When the sorting control in the work mode 2 is started, and the stick detection sensor (S ₀ ) is OFF and the stick is not supplied, the sorting control is automatically adjusted to the preset target sorting state. Since the selection control of mode 1 or mode 3 is activated, the operation corresponds to the work state detecting means for detecting whether or not the grain stick detection sensor (S ₀ ) is in the cutting work state.

In addition, the control status display lamp (37) is turned on when the selection control in the mode 2 for the mowing work is activated, and when the selection control in the mode 1 or the mode 3 for the non-cutting work is activated. Since the control status display lamp (37) is turned off, the control status display lamp (37) is switched to the sorting control means (102).
Corresponds to a display means for displaying whether the sorting control in the mode 2 for mowing work is activated or the sorting control in mode 1 or mode 3 for non-cutting work.

When the type of grain rod is soybean, and when the automatic switch (SW ₁ ) is in the manual mode selection state, the chaff opening degree and the turtle air volume are set by the setting device (regardless of the detection state of various sensors). S _4), thereby to maintain the target value set by the (S _5). However, although not described in detail, when the manual mode is selected, the target value set by the setting devices (S ₄ ) and (S ₅ ) is smaller than the set value corresponding to the state where the processing amount is small. If it is set to, in order to inform that it is erroneous, the grain桿検detection sensor (S ₀₎ is in accordance with the changes to oN from OFF, the alarm (3
5) is activated to give an alarm.

By the way, the reel (6) of the pre-cutting unit (4) can change the drive rotational speed by using a split pulley type transmission like the Karin (11).

In addition, as shown in FIGS. 13 and 14, a pair of input pulleys (38) and output pulleys (39) attached to the side surfaces of the pre-cutting unit (4) are both split pulleys. When one of the diameters is changed to the large side by the shifting arm (40) that slides in the lateral direction of the machine body, the other diameter is changed to the small side in conjunction with the change. The shifting arm (40) is provided with a link member (43) linked to a nut (42) externally engaged with a screw shaft (41) rotatably driven by an electric motor (M ₃ ) as an actuator. It is designed to be slid toward. In the figure, (S ₇ ) is a potentiometer type sensor for detecting the operation stroke of the shifting arm (40), and (SW ₃ ) and (SW ₄ ) are the shifting arm (40).
Are a pair of limit switch type sensors for detecting whether the operation upper limit or the operation lower limit has been reached.

The amount of air supplied to 1) may be varied to adjust the air flow, and the specific configuration for changing and adjusting the air flow of the tow may be variously changed.

Further, in the above embodiment, the case where the amount of the material to be leaked from the handling room (A) is detected based on the vehicle speed is exemplified. However, for example, the detection may be performed based on the torque of the handling cylinder (12). The detection may be performed based on the drive torque of the auger (8) or the scraping / conveying unit (9), and the specific configuration of the processing amount detection means (100) can be variously changed.

Further, in the above-described embodiment, the case where the contact type grain stick detection sensor (S ₀ ) is provided in the handling room (A) to determine the start of cutting and the end of cutting is exemplified. In the same manner as in the means (100), the detection may be performed based on the torque change of the handling cylinder (12) and the driving torque of the auger (8) and the scraping-up conveyance section (9). The specific configuration for determining whether or not there is any change can be variously changed.

Further, in the above-described embodiment, the case where the present invention is applied to the all-rods-in-type combine is illustrated. However, the present invention is also applicable to a so-called self-removing combine, and the structure and the structure of the threshing device (3) The specific configuration of each part such as a structure for changing and adjusting the sorting state of the sorting device (B) can be variously changed.
