The bottom spiral (cereal grain-discharging device) 10 that the grain that stores in the grain case 3 of combine is provided with from the bottom at grain case 3 is discharged.Constituting of this bottom spiral (cereal grain-discharging device) 10: as shown in Figure 3; Bottom at grain case 3 is equiped with axle; The top of axle is connected on the power transmission shaft 11 outside the machine through discharging clutch 12, and the end side of axle extends to the bottom of the tube 4 of winnowing and is connected to the bottom of the spiral 13 of winnowing of interior dress.

And, row's paddy spiral part 5 (Fig. 4) by the top that can on above-below direction, be connected to the above-mentioned tube 4 of winnowing free lifting fixedly transport tube 6 with fixedly transport tins 6 be connected mobilely transport tins 7 and constitute, specify its structure below.

At first; As shown in Figure 4; Fixedly transport tube 6 constitute: its base portion is connected to the top of the above-mentioned tube 4 of winnowing, and its leading section prolongs to foreign side, top portion is housed in the tube is connected to transporting spiral 14 and transporting from the grain of tube 4 acceptance of winnowing of the above-mentioned spiral 13 of winnowing fixedly transporting.

As shown in Figure 4, the mobile tube 7 that transports offers the outlet 9 of arranging the paddy spiral part at leading section, and its base portion side can be transported tube 6 with said fixing with being free to slide and is connected.In addition; The structure of flexible spiral 15 is as shown in Figure 4; Transport in the tube 7 mobile; Its leading section is supported on the top position of arranging paddy spiral part outlet 9 with bearing, and its rear portion extends to fixedly to transport tube 6 sides and set up and is inserted into the above-mentioned interior power transmission shaft 16 of axle that transports spiral 14 with being free to slide, can be embedded with a plurality of helical elements on this power transmission shaft 16 with being free to slide and can adjust the space.

In addition, as shown in Figure 4, the constituting of retractable driving device 23: upper position equipment flexible that the base end part of helical axis 25 is connected to the tube 4 of winnowing through deceleration device with CD-ROM drive motor 24 on, through flexible with CD-ROM drive motor 24 pressure driving helical axis 25.And the trundle that the structure of mobile device 26 is designed to cooperate through the helicla flute with above-mentioned helical axis 25 moves by the strong hand in the axial direction, and links into an integrated entity with base portion side that said fixing is transported tube 6.

Have again; The structure of retractable driving device 23 is as shown in Figure 4; Contracting of row's paddy spiral part 5 the shortest side with stretch to such an extent that the longest side is respectively equipped with limit sensors S1 and S2; When above-mentioned mobile device 26 arrives limit sensors S1 or limit sensors S2, then stop flexible automatically with CD-ROM drive motor 24.

In addition, can carry out multiple variation though move the position of the leading section that transports tube 7,, the position of the leading section of row paddy spiral part 5 is contained in the row paddy spiral part support portion 35 in the majority in the centre position of the length of fast moving formula row paddy spiral part 5.

Also have, the flexible structure of CD-ROM drive motor 24 of using is that the opening operation according to the upward set switch of the guidance panel (not shown) of control cabinl pulpit 40 (flexible switch) is driven and carries out forward or reverse, thereby drives helical axis 25 rotations; If helical axis 25 is just changeing, then make to move and transport tube 7 elongations, if counter-rotating then forcibly move to shortening direction through the mobile device 26 that cooperates.

Like this; Moving the structure of transporting tube 7 does; Fixedly transport tube 6 state lower edge and fixedly transport tube 6 and stretch being embedded into; And make its leading section row paddy spiral part outlet 9 the position with respect to the base portion of row's paddy spiral part 5 winnow tube 4 away from or closely adjust, thereby can select the lowering position of grain.

Have again; In Fig. 4; Elevating oil cylinder 27 row's of making paddy spiral parts 5 go up and down, row paddy spiral part rotation motor 28 through with the winnow rotation of tube 4 of set driven wheel 30 on the outer circumference portion of the tube 4 of winnowing of swing pinion set in its rotating shaft 29 engagements.

And the structure of support roller 31 is as shown in Figure 4, is erected at the bottom of moving the base position of transporting tube 7, and support fixation is transported tube 6 when the periphery that fixedly transports tube 6 is rotated.In addition, be provided with guiding wheel 32 on the top of moving the base position of transporting tube 7, and be provided with the guide rail (not shown) of this guiding wheel 32 of guiding along the length direction that fixedly transports tube 6.

If plant the harvesting operation of paddy bar when combine like above-mentioned structure is advanced; Then planting the paddy bar is gathered in by reaping apparatus 34 (Fig. 1); Then, be transported to the top portion of sheller unit 37, and when transporting, carry out the threshing screening by the feeding chain.Grain by sheller unit 37 threshings screening is stored temporarily in the grain case 3; When filling grain in this grain case 3; Then the row of making paddy spiral part 5 leaves from row's paddy spiral part support portion 35 (Fig. 4), and to the compartment of truck etc., discharges grain from this row paddy spiral part 5.

At this moment, if when the position of the outlet 9 of row's paddy spiral part does not reach the length in the compartment of truck etc., then elongation is moved and is transported tube 7 can discharge grain further.And, the mobile tube 7 that transports is stretched so that grain is discharged in the lorry compartment equably.Like this, during grain in finish discharging grain case 3, then will arrange paddy spiral part 5 once more in the row of the being contained in paddy spiral part support portion 35.

The mobile flexible spiral 15 that transports tube 7 shown in Figure 4 is made up of plastic a plurality of helical elements.

In addition; Though Fig. 5 is the simple block diagram of the control device 50 relevant with the control of the row paddy spiral part 5 of embodiment of the present invention; But; Discharge switch 46 that the clutch of clutch 12 uses, discharge clutch apparatus position-detection sensor 48, discharge mode selection switch 53, the accelerator position sensor 49 of engine and the input side that engine rotation sensor 57 all is connected to control device 50, on the outlet side of control device 50, then be provided with the tension motor 44 of discharging clutch and lamp 47 etc.

Motor driven power is delivered to the clutch for clutch control of the discharge clutch 12 (with reference to Fig. 4) of the bottom spiral 10 in the grain case 3, and the tension motor 44 by start-up control regulating wheel 45 carries out in the present embodiment.The switch of this motor 44 carries out with electric power, and lighting and extinguish the state that can discern the clutch for clutch control of discharging clutch 12 through lamp 47.

In the present embodiment, as shown in Figure 5, the switch 46 that is provided with instantaneous formula when the driver opens this switch 46, is discharged clutch 12 as the Isolating Switch of discharging clutch 12 in order to close, tension motor 44 entrys into service, and tension arm 44a starts working.Meanwhile, lamp 47 is lighted.

As shown in Figure 6, discharge clutch position detecting sensor 48 and detect the position (A) that this tension arm 44a starts working, and this position (A) is stored in the memory in the control device 50 in advance.That is,,, the driver starts working so can confirming tension arm 44a because tension arm 44a lamp 47 when leaving position (A) is slightly lighted.But at this moment, tension arm 44a does not move to the position that tightener sheave 44b makes the state of discharging clutch 12 runnings.

Thereafter, if tension arm 44a moves scheduled volume, then tightener sheave 44b rotates belt 43 tensionings and belt pulley 45, discharges clutch 12 entrys into service.At this moment; The electric power that stops tension motor 44 is supplied with; Simultaneously, discharge the position (B) that clutch position detecting sensor 48 detects these discharge clutch 12 entrys into service (state that belt pulley 45 begins to rotate), and this position (B) is stored in the memory in the control device 50.At this moment, lamp 47 is lighted.

As above above-mentioned, at tightener sheave 44b belt 43 tensionings and belt pulley 45 are rotated, under the state of driving discharge clutch 12 engine is stopped, when making power supply become the state of connection once more, then lamp 47 is lighted.Under such state, engine start electricity key forwards the engine start side to and engine does not start.For ato unit once more, console switch 46, and make tension arm 44a get back to position (A) at once.Make engine start electricity key forward engine start side, then engine start under the state of position (A) if get back at tension arm 44a.Like this, can prevent the unexpected grain of discharging.

If connect above-mentioned switch 46 and tension arm 44a moves to the process of position (B) from position (A), engine stopped, then tension arm 44a be in transit in the state of position.Then, if become the state of energized once more, then tension arm 44a is in the state that middle position in transit stops, and lamp 47 is also lighted.Under such state, forward engine start electricity key to the engine start side, then engine does not start.In this type of situation, if console switch 46, then tension motor 44 entrys into service, then tension arm 44a moves to position (A), and lamp 47 extinguishes.Like this, but ato unit.

That is, rolling motor starts electric key (not shown) and energized, even be not delivered under the state of belt pulley 45 at power, (A) leaves if tension arm 44a is from the position, and then lamp 47 is lighted.If this lamp 47 is illuminating states, even then the driver forwards engine start electricity key to the engine start side, engine is not opened moving yet.This is because owing to opened discharge clutch 12, so suppose that then the bottom spiral (cereal grain-discharging device) 10 of grain case 3 might rotate like engine start, grain is all of a sudden discharged.That is, belt 43 produces swing with tightener sheave 44b owing to vibration waits, and its result when belt pulley 45 rotates intermittently, though grain might all of a sudden be discharged, still can prevent trouble before it happens this type of undesirable condition.

Like this, will make and discharge that clutch 12 is in open mode and belt pulley 45 begins to rotate, thereby can the situation that grain is all of a sudden discharged be prevented trouble before it happens.Under such state; If push switch 46 then tension motor 44 starts; Owing to have a structure that makes tightener sheave 44b get back to stop position (A), so if the moment rolling motor of getting back to stop position (A) at tightener sheave 44b starts electric key, then can heuristic moving engine.

Then; If in the operating condition of discharging clutch 12; Be that state ShiShimonoseki make and break that belt pulley 45 rotates closes 46; Then tension motor 44 entrys into service, tension arm 44a is from discharging the position that clutch 12 closes, i.e. and the position (B) of 12 runnings of the discharge clutch apparatus under tightener sheave 44b tightening belt 43 states turns back to stop position (A).At this moment, even close the operation of switch 46, lamp 47 can not extinguish at once yet.The formation of extinguishing of lamp 47 is that lamp 47 also extinguishes when tension arm 44a comes position (A) and tension motor 44 and stops.

That is, if close switch 46, though tension arm 44a leaves position (B) at once, under the state that tension arm 44a leaves from belt 43 a little, because tightener sheave 44b also only leaves belt 43 a little, so produced so-called phenomenon of trailing.What is called is trailed phenomenon and is meant that tightener sheave 44b waits moment tightening belt 43 and to the phenomenon of belt pulley 45 transferring power because of vibration.Trail phenomenon if produce this, then belt pulley 45 rotates intermittently.

Therefore, extinguishing when tension arm 44a comes position (A) of lamp 47 carries out.

Like this, know just that by closing of lamp 47 discharging clutch 12 is in the state that breaks off fully, promptly tightener sheave 44b leaves from belt 43 fully.At this moment; Because but basis is in the state of ato unit from the signal control device 50 of the position-detection sensor 48 of discharging clutch; So after engine start electricity key being rotated and engine is stopped; Under the situation of ato unit, if rolling motor starts electric key, then engine can start at once once more.Even ato unit under such state, grain can all of a sudden not discharged yet.

In addition, if close above-mentioned switch 46 and move to shutting engine down (state that power supply also breaks off) the process of position (A) from position (B) at tension arm 44a, then tension arm 44a is in the state of position on the way.Then, if become the state of power connection once more, because tension arm 44a is in the state that middle position in transit stops, so lamp 47 also is the state of lighting.Under such state, even make engine start electricity key forward the engine start side to, engine does not start yet.In such situation, if pressing operation switch 46, then tension motor 44 entrys into service, tension arm 44a moves to position (A), and lamp 47 extinguishes.Like this, but ato unit.

In addition, if close above-mentioned switch 46 and the process that moves to position (A) from position (B), make engine stop (state of power connection) at tension arm 44a, then tension arm 44a is in the state of position on the way.Under this state, because tension arm 44a is in the state that middle position in transit stops, so lamp 47 also is in the state of lighting.Under such state, even forward engine start electricity key to the engine start side, engine does not start yet.In such situation, if pressing operation switch 46, then tension motor 44 entrys into service, tension arm 44a moves to position (A), and lamp 47 extinguishes.Like this, but ato unit.

Like this, lighting and extinguishing and make the structure that the detected value according to the position-detection sensor 48 of discharging clutch switches of lamp 47 do not have related with the folding of switch 46.And, the lighting and extinguish the clutch of confirming to discharge clutch 12 of lamp 47 capable of using, simultaneously, can only be discharging the startup that carry out engine under the state that clutch 12 breaks off fully, to guarantee safety.

As above above-mentioned, if owing to adopted tension arm 44a (A) leaves a little from the position,, discharge so can not carry out grain even rolling motor starts the structure that electric key can not ato unit.In addition; 44a checks operation and tension arm 44a is left under the state of position (A) a little at other operator grasps tension arms; If other operators make engine start; In the hole though belt 43 rotates with belt pulley 45, pass through as above above-mentioned structure, even the operator of driver's seat unconsciously rolling motor start electric key and want ato unit; Because if control device 50 adopts tension arm 44a to leave the structure that position (A) engine does not start a little, so can guarantee safety.

The discharge clutch position detecting sensor 48 that detects the clutch position of above-mentioned discharge clutch 12 is used the potentiometer (not shown) of position of the tension arm 44a of the running position of detecting the formed belt 43 of above-mentioned tightener sheave 44b respectively and stop position.Near the limit switch (not shown) that is disposed the wobble area of the tension arm 44a that also can use at the running position of the formed belt 43 of above-mentioned tightener sheave 44b and stop position in addition, replaces potentiometer.

Have again, as other instances of the discharge clutch position detecting sensor 48 that detects the clutch position of discharging clutch 12, the limit switch (not shown) of discharging in the clutch tension motor 44 that is contained in capable of using.At this moment, if this limit switch takes to detect the structure of the operating position of the tension arm 44a when discharging clutch 12 disconnections, then the limit switch of available cheapness detects the position of discharging clutch 12.

And, adopt following structure: discharge clutch 12 when closing fully when detecting in the operating position of tension arm 44a with this limit switch, but ato unit then.

With near two limit switches of the configuration wobble area of the both sides of tension arm 44a in the past; In order to detect to discharge clutch apparatus 12 whether tensioning structure relatively; Owing to only use one to be contained in the position-detection sensor 48 that the limit switch of discharging in the clutch tension motor 44 is used as the discharge clutch, so can constitute at an easy rate.In addition owing to break off sides and use limit switches discharging clutch 12, so only discharge clutch 12 when being in the state that breaks off fully lamp 47 extinguish because engine can start, so the driver is easy to understand.

Have the mechanism that makes above-mentioned discharge clutch 12 work of present embodiment through tension motor 44, and can carry out being provided with the switch 53 that to select the pattern of discharging from the grain of grain case 3 in the combine of this work control.

And, when not operating above-mentioned grain and discharge mode selection switch 53, can carry out common grain and discharge continuously with switch 46 as the grain waste cock.In addition, when operation grain is discharged mode selection switch 53, be employed in to discharge and begin through automatically stopping to discharge the structure of grain after the scheduled time from row paddy spiral part 5 from grain.

The reason that this grain discharge mode selection switch 53 is set is to eliminate following undesirable condition when (be called as the so-called grain that packs and discharge operation) for the operation of discharging at the sacks of directly using to splendid attire grain from the row paddy spiral part outlet 9 of row paddy spiral part 5.That is, so-called pack operation is, though the operator in the control cabinl pulpit 40 begins the grain discharging operation; On the other hand, the support staff outside combine is supportting sack and is receiving grain near the outlet 9 of the leading section of row paddy spiral part 5; But the operator carries out the grain discharging operation according to support staff's gesture when this operation; Perhaps stop this operation, when inconsistent, then can produce grain and spill into the outer unfavorable condition of sack in both time.

For addressing the above problem, discharge mode selection switch 53 through opening grain, can one carry out grain and discharge operation, thereby the discharging operation when making pack becomes very simple by the mode of discharging grain in right amount or slightly at every turn.And, even forgetting, the contingency operator is in the so-called pack operation, owing to beginning from the grain discharge through automatically stopping after the scheduled time from row paddy spiral part 5 discharge grain, so grain can not overflow from sack.

In addition, when carrying out under the state of not pushing discharge mode selection switch 53, push sometimes and discharge mode selection switch 53 from row paddy spiral part 5 discharge grain.

In this case, with the control that stops to discharge grain at once.This is because because the possibility of maloperation is arranged, so at first discharge through promptly stopping grain, can be avoided discharging in vain grain when grain is discharged.

Have again, exist to have forgotten to push and discharge mode selection switch 53, be used to carry out the switch 46 that common grain is discharged and pushed, and the so-called packed situation of beginning.The operator finds to have forgotten to push to discharge mode selection switch 53 and press the situation of discharging mode selection switch 53 in a great rush in packed process though have; If discharge and stop control, then can stop the leeway that grain is discharged and fallen and the operation that next will carry out is considered but carry out above-mentioned grain this moment at once.

In addition, can reduce the grain velocity of discharge and slowly discharge grain, stop control to replace above-mentioned grain to discharge.At this moment, through engine revolution being dropped to for example below the rated revolution, can reduce the grain velocity of discharge.

On the other hand; Discharge mode selection switch 53 and in carrying out the grain discharging operation, cut off discharge mode selection switch 53 even connect; Also can make grain discharge the scheduled time that sets when running lasts till beginning, the grain of exercising the packed completion that has begun of going forward side by side is discharged control.

Have again; The pattern that can adopt has: at connection discharge mode selection switch 53 and when implementation grain discharging operation breaks discharge mode selection switch 53; If connect the switch 46 that grain is discharged usefulness; Then still carry out common grain continuously and discharge running, when cut-off switch 46, then stop grain and discharge.

Also have, when pushing discharge mode selection switch 53, can use the engine revolution of engine rotation sensor 57 detection combines, and according to detected engine revolution, setting begins to be discharged to the time that stops from grain.This is because the revolution and the engine revolution of grain case bottom spiral (cereal grain-discharging device) 10 that is used for discharging from grain case 3 grain is proportional, thereby can make the discharge rate of grain certain through this control.

And; Have at combine under the situation of engine revolution controlling organization; Discharge mode selection switch 53 if press, the low predetermined number of revolutions of engine revolution of (carrying out grain with specified engine revolution usually discharges) in the time of engine revolution being dropped to discharge than common grain.

This be because, owing to consider that when so-called packed operation began, the support staff did not have packed preparation at heart, thus when packed, adjust the grain velocity of discharge slower so-called, thereby safety and carry out this operation simply.
