In this existing sheller unit, have the revolving drum of breaing up tooth owing to be provided with, thereby can suppress to take off unclean rate and penetrate the generation of loss (being rolled into the incomplete phenomenon of threshing that the handled thing on the threshing cylinder of rotation is directly discharged from drum chamber under butt penetrates situation in the straw grass) etc. in the downstream of the handled thing throughput direction of drum chamber dust mouth.

Yet, though can suppress to take off unclean rate and penetrate loss, but then, when the opposition side of the handled thing of the opposition side that focuses on conveyer chain one side along with the rotation of threshing cylinder deflection conveyer chain one side and from the dust mouth of drum chamber when the downstream of throughput direction is supplied with, owing to have the revolving drum of breaing up tooth is not carried ability from handled thing to conveyer chain one side, thereby supply to the handled thing of revolving drum from the dust mouth deflection of drum chamber at the opposition side of conveyer chain one side, will still keep this amesiality state to supply with to oscillatory sorting device and dust-exhausting port.Therefore, exist the big problem of what is called three class product losses that low problem of the efficiency of separation in the oscillatory sorting device and grain are discharged from dust-exhausting port.

In order to address the above problem, can consider on revolving drum, to be provided with helical blade, with this revolving drum the processing limit is broken up on the handled thing limit of supplying with from the dust mouth deflection of drum chamber and carry, thereby supply with handled thing equably to oscillatory sorting device and dust-exhausting port to conveyer chain one side.

But, even helical blade is set, only can on the periphery of revolving drum, not form the resistance that handled thing is carried to conveyer chain one side by the helical blade that is arranged on the revolving drum on revolving drum yet, exist the low problem of conveying capacity.Otherwise, if improve conveying capacity and the periphery that will have the revolving drum of helical blade as common conveying worm fences up with cartridge, then it is contemplated that, can occur this cartridge form excessive resistance cause conveying capacity too high and with handled thing be transported to too much conveyer chain one side problem and, blocking problem takes place in handled thing on the periphery of revolving drum.

Summary of the invention

The objective of the invention is,, provide a kind of and can evenly and glibly supply with handled thing to oscillatory sorting device and dust-exhausting port and can prevent the sheller unit of efficiency of separation variation by working hard aspect revolving drum and the peripheral structure thereof.

For achieving the above object, the 1st feature structure according to sheller unit of the present invention is, comprising that have can be around carrying in the sheller unit of the conveyer chain that the horizontal side of the drum chamber of the threshing cylinder of the axle center of handled thing throughput direction rotation and the described drum chamber on described handled thing throughput direction extends, it is characterized in that

Above described revolving drum, be provided with guide member, be formed with opening on this guide member.

According to this feature structure, above the periphery of revolving drum, guide member is set, therefore, the revolving drum that periphery is provided with helical blade is handled the limit when conveyer chain one side is carried to breaing up from the handled thing limit of the dust-exhausting port of drum chamber, this guide member can form resistance, improves the conveying capacity that periphery is provided with the revolving drum of helical blade.

In addition, on guide member, form opening, can prevent that guide member from forming excessive resistance with handled thing when conveyer chain one side is carried.

It is contemplated that thus, owing to can improve the conveying capacity that periphery is provided with the revolving drum of helical blade, thereby the handled thing after handling through the threshing cylinder threshing can not supplied with oscillatory sorting device and dust-exhausting port not amesialityly equably, prevent that the efficiency of separation in the oscillatory sorting device from reducing, and reduces the three class product losses that grain is discharged from dust-exhausting port.

In addition, owing to can prevent that guide member from forming excessive resistance with handled thing when conveyer chain one side is carried, thereby it is too high to prevent that periphery is provided with the conveying capacity of revolving drum of helical blade, prevents that handled thing from stopping up on the periphery of revolving drum.That is, can evenly and glibly supply with handled thing to oscillatory sorting device and dust-exhausting port.

Described guide member for example can be made of a plurality of bars, also can be made of the sheet material with porous portion.

In addition, the 2nd feature structure according to sheller unit of the present invention is, comprising that have can be around carrying in the drum chamber of the threshing cylinder of the axle center of handled thing throughput direction rotation and for to described threshing cylinder transport process thing and in the conveyer chain that the horizontal side of described drum chamber extends, it is characterized in that

In order to be transported to described conveyer chain one side from the handled thing of the dust mouth of described drum chamber, being provided with can be around the revolving drum perpendicular to the band helical blade of the axle center rotation of described throughput direction, and,

A plurality of the 1st screening parts are installed on the oscillatory sorting device of the below that is positioned at described drum chamber, and extend to the below of described revolving drum from this oscillatory sorting device, and are formed with the gap between these the 1st screening parts.

According to this feature structure, the 1st screening part extends to the below of revolving drum from the oscillatory sorting device of the below that is positioned at drum chamber, because of than, the revolving drum that this screening part can periphery be provided with helical blade is handled the limit forms resistance when conveyer chain one side is carried breaing up from the handled thing limit of the dust-exhausting port of drum chamber, and the raising periphery is provided with the conveying capacity of the revolving drum of helical blade.

In addition, on the 1st screening part, form opening or gap, can prevent that screening part from forming excessive resistance with handled thing when conveyer chain one side is carried.

It is contemplated that thus, owing to can improve the conveying capacity that periphery is provided with the revolving drum of helical blade, thereby the handled thing after handling through the threshing cylinder threshing can not supplied with oscillatory sorting device and dust-exhausting port not amesialityly equably, prevent that the efficiency of separation in the oscillatory sorting device from reducing, and reduces the three class product losses that grain is discharged from dust-exhausting port.

In addition, owing to can prevent that screening part from forming excessive resistance with handled thing when conveyer chain one side is carried, thereby it is too high to prevent that periphery is provided with the conveying capacity of revolving drum of helical blade, prevents that handled thing from stopping up on the periphery of revolving drum.That is, can evenly and glibly supply with handled thing to oscillatory sorting device and dust-exhausting port.

According to sheller unit of the present invention, can also on the basis of above-mentioned a certain feature structure, have following feature structure.

For example, in a preferred forms, described oscillatory sorting device has: be arranged on described drum chamber the below, carry the limit to carry out the preceding grain pan and the back grain pan of sorting process to fallen handled thing limit from drum chamber, and to carry the limit to carry out the straw grass sieve of sorting process from the handled thing limit in the above-mentioned grain pan;

Described the 1st screening part is arranged on the end of described back grain pan, and the 2nd screening part is arranged on the end of described preceding grain pan, and,

Described the 2nd screening part constitutes to the elastomeric material of the downstream of described handled thing throughput direction one side extension by being the end of single-ended stationary state from described preceding grain pan.Constitute like this, more favourable from the following aspect.

Technology as existing sorting bilge construction, for example disclosed as Japanese kokai publication hei 11-225560 communique, end at grain pan is provided as the routine screening line of one of the 2nd screening part, and is known with the sorting bilge construction that promotes the sheller unit that separates, improves the grain and the careless efficiency of separation of considering to be worth doing of straw that grain and straw grass is considered to be worth doing.In addition, disclosed as TOHKEMY 2000-201524 communique, screening line as one of the 2nd screening part on the end that is arranged on grain pan example is swung up and down, known to promote grain with the sorting bilge construction of the sheller unit of the efficiency of separation of separating, improve grain and straw grass bits of straw grass bits.

Disclosed as Japanese kokai publication hei 11-225560 communique, the screening line is set on the end of grain pan, utilize this screening line that the handled thing piece that falls to straw grass sieve from grain pan is scattered or make upwards spring of handled thing, can promote separating of grain and straw grass bits.In addition, the screening line that is arranged on the grain pan end is swung up and down, with will screen line and be fixed up and compare, the block high efficiency of handled thing is scattered, the handled thing high high bounce that makes progress can also be made, thereby separating of grain and straw grass bits can be promoted better.

But, as if the screening line of being put down in writing as TOHKEMY 2000-201524 communique, thereby use lever or roller to make oscillatory sorting device and screening line interlock that the screening line is swung up and down, then roller will move forward and backward regularly with respect to the swing of oscillatory sorting device, causes screening line with certain speed swing.Therefore, for example when the amount increase and decrease of handled thing, the efficiency of separation of screening line will produce difference.It is contemplated that thus,, just the block of handled thing is scattered more efficiently, handled thing is more popped up on the highland, thereby improve the efficiency of separation as long as can make the swing of screening line quick irregular.

With respect to this, according to above-mentioned feature structure of the present invention, the 2nd screening part is set at the end of grain pan, therefore, when supplying on the end of grain pan when the oscillatory sorting device swing, with handled thing, this handled thing just contacts with the 2nd screening part.In case handled thing contacts with screening part, the block of handled thing is scattered, and handled thing can be popped up, thereby promote grain and separating that the straw grass is considered to be worth doing.

In addition, making the 2nd screening part be single-ended stationary state extends towards the downstream of handled thing throughput direction from the end of grain pan, and constitute the 2nd screening part with elastomeric material, therefore, in case oscillatory sorting device is swung, being single-ended stationary state is that fulcrum utilizes the strain of the screening part of elastomeric material formation itself to swing up and down with the end of grain pan just to the 2nd screening part of the downstream extension of handled thing throughput direction.So, except the swing of oscillatory sorting device, add the effect of the recuperability that strain produced of the 2nd screening part itself, screening part is swung fast and brokenly.

Owing to make screening part be single-ended stationary state as mentioned above from the end of grain pan downstream extension to the handled thing throughput direction, and constitute this screening part, thereby needn't for example as the screening line, take the structure of using lever or roller to make it to swing with elastomeric material.

Therefore, can promote separating of grain and straw grass bits, thus at rotary fan when the end of grain pan provides sorting wind, the heavier grain of conduct oneself with dignity will fall, the straw of conduct oneself with dignity lighter are careless considers to be worth doing then by the downstream of sorting wind band to the handled thing throughput direction.Therefore, can carry out the sorting of grain and straw grass bits.

In addition, can think, because screening part is vibrated fast and brokenly, thereby the block of handled thing is efficiently scattered, with the high upward high bounce of handled thing.Therefore, can promote grain and separating that the straw grass is considered to be worth doing better, thereby improve the efficiency of separation of grain and straw grass bits.

In addition, owing to do not need to adopt the structure that makes it to vibrate with lever or roller, thereby the structure of screening part vibration can be realized simply.Therefore, thus can reduce number of components and parts and reduce manufacturing cost.

In a preferred forms, described threshing cylinder has preceding threshing cylinder and can be with respect to the counterrotating rear threshing roller of this preceding threshing cylinder,

The barrel dliameter of threshing cylinder and the barrel dliameter of described rear threshing roller design roughly the samely before described,

Below described threshing cylinder, be provided with can make and carry out the spacer screen that the handled thing after threshing is handled leaks down through this threshing cylinder, the end of the conveyance direction downstream side of this spacer screen is positioned at the below of the boundary portion of described preceding threshing cylinder and rear threshing roller.Constitute like this, more favourable from the following aspect.

As prior art, for example as TOHKEMY 2006-75128 communique is disclosed threshing cylinder is divided into before threshing cylinder and rear threshing roller, rear threshing roller with the sheller unit of the speed rotation higher than preceding threshing cylinder, and the sheller unit that revolving drum is set as the disclosed handled thing conveyance direction downstream side in the drum chamber dust mouth of TOHKEMY 2003-38 communique is known.

As TOHKEMY 2006-75128 communique is disclosed, make rear threshing roller with the speed rotation higher, can reduce and take off unclean rate and penetrate loss than preceding threshing cylinder.In addition, the setting of revolving drum also can reduce and takes off unclean rate and penetrate loss.

Yet, take off unclean rate and penetrate loss though can reduce, but then, if with the threshing cylinder separated into two parts and make rear threshing roller with than the rotation of the higher speed of preceding threshing cylinder, then can make the opposition side that focuses on conveyer chain one side through the handled thing after the threshing processing in a large number, the handled thing after handling through threshing will be partial to the opposition side of conveyer chain one side and be supplied with to the downstream of throughput direction from the dust mouth of drum chamber.So, even if as TOHKEMY 2003-38 communique is disclosed, downstream at the handled thing throughput direction of the dust mouth of drum chamber is provided with revolving drum, also because this revolving drum does not have the ability that handled thing is carried to conveyer chain one side, thereby the opposition side of deflection conveyer chain one side is supplied with revolving drum from the dust mouth of drum chamber handled thing will still keep this amesiality state to supply with to oscillatory sorting device and dust-exhausting port.Therefore, exist the big problem of what is called three class product losses that low problem of the efficiency of separation in the oscillatory sorting device and grain are discharged from dust-exhausting port.

It is contemplated that thus, as long as the handled thing after threshing can being handled is not partial to the opposition side ground of conveyer chain one side and not supplied with oscillatory sorting device and dust-exhausting port equably, just can prevent the low problem generation of the efficiency of separation in the dust mouth of above-mentioned oscillatory sorting device and drum chamber.

With respect to this, work hard by configuration aspects at revolving drum, the present invention can prevent that the efficiency of separation from reducing when effectively reduction is taken off unclean rate and penetrated loss.

That is, threshing cylinder is designed to the rotary speed height of the rotary speed of rear threshing roller, can reduces and take off unclean rate and penetrate loss than preceding threshing cylinder.And on the other hand, can focus on the opposition side of conveyer chain one side in a large number through the handled thing after the threshing processing.This handled thing that focuses on the opposition side of conveyer chain one side is in a large number supplied with the revolving drum in downstream of the handled thing throughput direction of the dust mouth be arranged on drum chamber, and broken up by the helical blade limit on the periphery that is arranged on this revolving drum and to handle the limit and carry to conveyer chain one side.That is to say, the handled thing that focuses on the opposition side of conveyer chain one side in a large number can be carried to conveyer chain one side by the helical blade on the periphery that is arranged on revolving drum.Therefore, the opposition side ground of the handled thing after handling through threshing can be partial to conveyer chain one side is supplied with oscillatory sorting device and dust-exhausting port equably.

At this moment, by the barrel dliameter of preceding threshing cylinder and the barrel dliameter of rear threshing roller are designed to identical degree, compare with the situation that for example designs the barrel dliameter of rear threshing roller littler than the barrel dliameter of preceding threshing cylinder, can make the periphery length lengthening of rear threshing roller, thereby a plurality of threshing teeth can be installed on the periphery of rear threshing roller.In addition, the barrel dliameter of rear threshing roller hour, the straw grass is wound on the rear threshing roller easily, and the barrel dliameter of preceding threshing cylinder and the barrel dliameter of rear threshing roller are designed to identical degree, can make the barrel dliameter of rear threshing roller bigger, thereby prevent that the straw grass is wound on the rear threshing roller.

In addition, the spacer screen that leaks down by the handled thing that can make after the threshing cylinder threshing is handled is arranged on the below of threshing cylinder, and the mode of the below of the boundary portion of threshing cylinder and rear threshing roller before spacer screen is positioned at the end of the conveyance direction downstream side of spacer screen and constituting can make to form the space that does not have spacer screen below rear threshing roller.So, the fringe end of the paddy bar of being supplied with by conveyer chain is formed below rear threshing roller not to have the space of spacer screen to let droop, and rear threshing roller can carry out threshing to the fringe end of the paddy bar that is in this hang to be handled.Therefore, the rear threshing roller fringe end whipping significantly that can make the paddy bar.

Therefore, handled thing after threshing can being handled is not partial to the opposition side ground of conveyer chain one side and is supplied with oscillatory sorting device and dust-exhausting port equably, thereby can handle effectively to reduce by breaing up of rear threshing roller and revolving drum and take off unclean rate and penetrate loss, prevent that the efficiency of separation in the oscillatory sorting device from reducing, and reduces the three class product losses that grain is discharged from dust-exhausting port.

In addition, owing on the periphery of rear threshing roller many threshing teeth can be installed, thereby a plurality of threshing teeth can be installed take off unclean rate and penetrate loss with effective reduction.

In addition, because the fringe end that rear threshing roller can make paddy bar whipping significantly, thereby can effectively reduce and take off unclean rate and penetrate loss.

For example in a preferred forms, described drum chamber is made of upper shell that is provided with described threshing cylinder and the lower house that is provided with the spacer screen of the below that is positioned at described threshing cylinder,

Described upper shell is connected on the described lower house, and can approach the job position of described spacer screen and described threshing cylinder at described threshing cylinder and carry out opening and closing operations between away from the maintenance position of described spacer screen, and,

Be provided with the fixation kit that constitutes in the mode that can between the disarm state that the stationary state and the permission that stop described upper shell from described job position displacement are shifted from described job position, switch and drive the switching driven unit that this fixation kit switches.Constitute like this, more favourable from the following aspect.

Opening and closing structure as existing sheller unit, have by the pair of locking bar that can be installed on the upper structure (upper shell) with freely swinging, and the locking mechanism (fixation kit) that is fixedly mounted in the formations such as pair of locking pin on the main structure body (lower house), when the hook of each securing rod is fastened on the corresponding locking pin, upper structure can be locked on the decline closed position (job position), when the hook of each securing rod is removed with the engaging of corresponding locking pin, upper structure can be removed at the lock-out state of decline closed position, and the locking of this locking mechanism and remove operation utilizes handle that the pair of locking bar is coupled together to carry out (for example can with reference to TOHKEMY 2001-190137 communique) with manual type.

According to above-mentioned prior art, when cutting the obstruction of receiving the paddy bar in the threshing path that is being formed between spacer screen and the threshing cylinder, can take place to engage bad phenomenon such as tension because of obstruction causes hook and locking pin, make that their fastening state is difficult to remove by manual operation, thereby will remove the stationary state of upper shell on the job position very trouble that will become.Its result, the measure that just may implement when upper shell is opened to maintenance position, solve threshing path two-story valley bar blockage problem is delayed enforcement, causes operating efficiency to reduce.

With respect to this, according to the present invention,, stops up by the paddy bar even if taking place in the threshing path, and the stationary state of upper shell on job position also is easy to remove, and can take measures to the obstruction of threshing path two-story valley bar rapidly.

Promptly, according to above-mentioned feature structure, even be formed to cut in the threshing path between spacer screen and the threshing cylinder and receive the obstruction of paddy bar, and, obstruction is fixed on state tension on the job position by fixation kit because of causing upper shell, also can rely on the action of switching driven unit to be easy to realize fixation kit from the switching of stationary state to disarm state, upper shell can carry out rapidly to opening of maintenance position from job position.

Therefore, can take measures to the obstruction of threshing path two-story valley bar rapidly, its result can improve operating efficiency.

In a preferred forms, the described upper shell of ratio above the described lower house and on the described handled thing throughput direction more position in downstream is provided with and effluxes straw grass conveying plant,

In described lower house, be provided with to get around and efflux the support frame of straw grass transport path can the mode that the described conveying initiating terminal that effluxes straw grass conveying plant supports being formed,

In described upper shell, be provided with the framework that extends towards described support frame,

Be provided with can and will connecting the coupling assembly that switches between the disarm state of removing and constitute in the coupled situation that described support frame and described framework are linked up, and,

Along with described fixation kit switches to disarm state from described stationary state, described coupling assembly switches to disarm state from coupled situation,

Along with described fixation kit switches to stationary state from described disarm state, described coupling assembly switches to coupled situation from disarm state.

Constitute like this, more favourable from the following aspect.

According to this feature structure, when making fixation kit switch to stationary state to stop upper shell when job position is opened from disarm state, coupling assembly will switch to coupled situation from disarm state thereupon, the support frame of lower house and the framework of upper shell are linked up, therefore, the conveying initiating terminal that effluxes straw grass conveying plant is not only by the support frame supports of lower house, but by the frame supported of this support frame and upper shell.

In addition, when making fixation kit switch to disarm state and allow upper shell when job position is opened from stationary state, coupling assembly will switch to disarm state from coupled situation thereupon, with the releasing that connects of the framework of the support frame of lower house and upper shell, thereby allow upper shell to open from job position.

Promptly, when upper shell being fixed on job position by fixation kit, do not need coupling assembly is switched to the trouble of coupled situation from disarm state, the conveying initiating terminal that effluxes straw grass conveying plant can be by the framework of the support frame of lower house and upper shell with higher support strength, better stability supports.

In addition, remove at the fixed solution that will be undertaken by fixation kit and to allow upper shell when job position is opened, do not need coupling assembly is switched to from coupled situation the trouble of disarm state, connecting reliably between the framework of support frame just that can realize by coupling assembly, lower house and upper shell removed, and upper shell can carry out rapidly from opening of job position.

And, owing to do not need the switching driven unit of the special use that the switching to coupling assembly drives, thereby can correspondingly seek the simplification of structure and the reduction of cost.

Therefore, except can simplified structure and reduce cost and improve the opening and closing operations of upper shell, can also improve with upper shell be fixed on job position when carrying out operation, to effluxing intensity and the stability that straw grass conveying plant supports.

As for the favourable effect of further feature structure and generation thereof, can read following explanation by the reference accompanying drawing and learn.

When the current location of upper shell 12 is job position, the opening operation instruction from opening switch 52 of this moment is judged as is intended to instruction that upper shell 12 is opened to the 2nd maintenance position from job position, and make the 1st electro-motor 68 and the counter-rotating of the 2nd electro-motor 70, thereby make fixation kit 58 switch to disarm state from stationary state according to this judgement.When motion detection assembly 72 detects when having switched to the releasing state by this counter-rotating fixation kit 58, just according to this testing result the 1st electro-motor 68 and the 2nd electro-motor 70 are quit work, afterwards, make the oil cylinder 55 of opening and closing drive component 51 extend action and make upper shell 12 open (rise and drive) to the 2nd maintenance position from job position.Detect when having arrived the 2nd maintenance position when opening and closing detection components 49, just make oil cylinder 55 stop to move and electro-motor 92 just being changeed, thereby engagement pin 90 is advanced by leaps and bounds towards the 2nd recess 45b according to this testing result by this elongation action upper shell 12.When detecting by this operation sheet dowel pin 90 of advancing by leaps and bounds, advance and retreat detection components 99 arrived when advancing by leaps and bounds extreme position, electro-motor 92 is quit work and light the 1st indicator lamp 93 that is arranged in the driver's cabin, inform that driver's upper shell 12 has arrived the 2nd maintenance position (with reference to Figure 14).

When the current location of upper shell 12 is the 2nd maintenance position, the opening operation instruction from opening switch 52 of this moment is judged as is intended to instruction that upper shell 12 is opened to the 1st maintenance position from the 2nd maintenance position, and make electro-motor 92 counter-rotating, thereby engagement pin 90 is kept out of the way to the direction that breaks away from the 2nd recess 45b according to this judgement.Keep out of the way operation sheet dowel pin 90 by this and arrived when keeping out of the way extreme position when advance and retreat detection components 99 detects, electro-motor 92 is quit work and make the oil cylinder 55 of opening and closing drive component 51 extend action, make upper shell 12 open (rise and drive) to the 1st maintenance position from the 1st maintenance position.Detect when having arrived the 1st maintenance position when opening and closing detection components 49, just make oil cylinder 55 stop to move and electro-motor 92 just being changeed, thereby engagement pin 90 is advanced by leaps and bounds towards the 1st recess 45a according to this testing result by this elongation action upper shell 12.When detecting by this operation sheet dowel pin 90 of advancing by leaps and bounds, advance and retreat detection components 99 arrived when advancing by leaps and bounds extreme position, electro-motor 92 is quit work and light the 1st indicator lamp 93, and light the 2nd indicator lamp 94 that is arranged in the driver's cabin, inform that driver's upper shell 12 has arrived the 1st maintenance position (with reference to Figure 15).

When the current location of upper shell 12 is the 1st maintenance position, the opening operation instruction is judged as maloperation, upper shell 12 is remained on the 1st maintenance position.

In addition, in case receive the shutoff operation instruction of upper shell 12 from closing switch 53, just according to the current location of judging upper shell 12 from the detection information that opens and closes detection components 49.

When the current location of upper shell 12 is the 1st maintenance position or the 2nd maintenance position, the shutoff operation instruction that comes self closing switch 53 of this moment is judged as the instruction that is intended to make upper shell 12 to close to job position from the 1st maintenance position or the 2nd maintenance position, and make electro-motor 92 counter-rotating, thereby engagement pin 90 is kept out of the way to the direction that breaks away from the 1st recess 45a according to this judgement.Keep out of the way operation sheet dowel pin 90 by this and arrived when keeping out of the way extreme position when advance and retreat detection components 99 detects, electro-motor 92 is quit work and make the oil cylinder 55 of opening and closing drive component 51 carry out contractive action, make upper shell 12 close (descend and drive) to job position from the 1st maintenance position or the 2nd maintenance position.Detect when having arrived job position when opening and closing detection components 49 by this contractive action upper shell 12, just make oil cylinder 55 stop action according to this testing result and the 1st electro-motor 68 and the 2nd electro-motor 70 are just being changeed, thereby make fixation kit 58 switch to stationary state from disarm state.When motion detection assembly 72 detects when just changeing fixation kit 58 and switched to stationary state by this, just according to this testing result the 1st electro-motor 68 and the 2nd electro-motor 70 are quit work, and the 2nd indicator lamp 94 or the 1st indicator lamp 93 are extinguished, inform that driver's upper shell 12 is fixed and held at (with reference to Figure 13) on the job position.

When the current location of upper shell 12 is job position, the shutoff operation instruction is judged as maloperation, upper shell 12 is remained on the job position.

That is to say, even if carry out the opening and closing operations of upper shell 12 at the driver's cabin of the opened and closed positions that is difficult to hold upper shell 12, by according to opening switch 52 or closing the open and close controlling assembly 50A that the operation of switch 53 is controlled, upper shell 12 is positioned among predefined job position and the 1st maintenance position and three positions of the 2nd maintenance position, with from opening switch 52 or closing on the corresponding position of instruction of switch 53, can avoid before upper shell 12 arrives these positions, will continuing to opening switch 52 or closing the trouble that switch 53 is operated.

When upper shell 12 was positioned at job position, along with open and close controlling assembly 50A controls according to instructing from the opening operation of opening switch 52, upper shell 12 will arrive the 2nd maintenance position.Its result, be used for sending the special switch that makes the instruction that upper shell 12 opens to the 1st maintenance position with being provided with, and, the scheme of the special switch of the instruction of opening to the 2nd maintenance position is compared, can avoid taking place this scheme contingent following bad phenomenon: because the incorrect switching when the threshing path 19 two-story valley bar plugging faults that taken place in the operation process are disposed, cause upper shell 12 to be opened to the 1st maintenance position from job position quickly, thereby be held cutting that conveying mechanism 22 clampings carry and receive the paddy bar, become the fringe end under its butt weight effect with conveyer chain 20 be fulcrum raise up significantly outwards below the posture that tilts be slipped to outside the car body.

And, be arranged in the driver's cabin by opening switch 52 and closing switch 53, for example when sheller unit 4 is safeguarded, can realize by sequence of operations: be intended to make and utilize hydraulic pressure that upper shell 12 is carried out the starting that opening operation becomes possible engine 9 at driver's cabin; Fixation kit 58 is from the switching of stationary state to disarm state; Coupling assembly 84 is from the switching of coupled situation to disarm state; Upper shell 12 is from job position opening to the 1st maintenance position or the 2nd maintenance position; Open stopping of rear engine 9.And after the maintenance to sheller unit 4 finishes, can realize by sequence of operations at driver's cabin: be intended to make and utilize hydraulic pressure that upper shell 12 is carried out the starting that shutoff operation becomes possible engine 9; Upper shell 12 is closing to job position from the 1st maintenance position or the 2nd maintenance position; Fixation kit 58 is from the switching of disarm state to stationary state; Coupling assembly 84 is from the switching of disarm state to coupled situation; Be fixed on stopping of job position rear engine 9.

Its result, the operability except can improve the opening and closing operations of upper shell 12 time, can also improve sheller unit 4 is carried out the replacing of the cleaning of spacer screen 16 and threshing cylinder 18 or spacer screen 16 and cutting of will stopping up received the paddy bar took out and be put into the first-class upkeep operation of conveying initiating terminal of conveyer chain 20 from threshing path 19 operability.

As shown in figure 12, in control device 50, has a kind of like this assembly 50B that pins down as control program, promptly, when the detection information according to the threshing clutch sensor 95 that detects from the operating state to the threshing clutch detects the closure state of clutch, the opening and closing operations of the handover operation and the upper shell 12 of fixation kit 58 and coupling assembly 84 is carried out in prevention by the control of open and close controlling assembly 50A, and light the 3rd indicator lamp 96 that is arranged in the driver's cabin, inform that driver's threshing clutch is in closure state, and detect the threshing clutch cut off state the time, allow to be undertaken the opening and closing operations of the handover operation and the upper shell 12 of fixation kit 58 and coupling assembly 84 by the control of open and close controlling assembly 50A.

Therefore, when making upper shell 12 be opened to the 1st maintenance position and the 2nd maintenance position, generation switches to the threshing clutch necessity of the state of cutting off, its result, when making upper shell 12 be opened to the 1st maintenance position or the 2nd maintenance position and sheller unit 4 safeguarded, formation from opening and closing drive component 51, even be necessary to make engine 9 work when upper shell 12 is opened, forget after perhaps opening engine 9 cuts out, out-of-work sheller unit 4 work halted states such as threshing cylinder 18 and conveyer chain 20 also can appear in the stage before carrying out upper shell 12 opening operations, and the maintenance of sheller unit 4 can be carried out under the work halted state of sheller unit 4.

Threshing clutch sensor 95 is made of the limit switch that is pushed to cutting off position operation along with the threshing clutch lever.

Pining down assembly 50B constitutes like this, promptly, detecting an output tube 8A in the detection information according to the outgoing position detection components 97 that detects from the operating position to the output tube 8A of grain output device 8 is not positioned at predefined upper shell and opens when using retreating position, the opening and closing operations of the handover operation and the upper shell 12 of fixation kit 58 and coupling assembly 84 is carried out in prevention by the control of open and close controlling assembly 50A, and light the 4th indicator lamp 98 that is arranged in the driver's cabin, inform that the driver exports a 8A and do not operate retreating position, and detect when being positioned at retreating position, allow to be undertaken the opening and closing operations of the handover operation and the upper shell 12 of fixation kit 58 and coupling assembly 84 by the control of open and close controlling assembly 50A.

Therefore, make upper shell 12 when the 1st maintenance position and the 2nd maintenance position are opened, the two comes in contact and impaired can to avoid upper shell 12 and output tube 8A.

The rotating potentiometer that outgoing position detection components 97 is detected by the lifting and swinging angle to output tube 8A and the rotating potentiometer that the angle of circling round of output tube 8A detects constituted.
