Abstract
A combine harvester comprises pedrail running gear, driving part, running gear of engine and working part consisted of reaping part, threshing part and grain container. This apparatus is equipped with a relatively moving mechanism for moving the running gear and working part relatively in a horizontal direction to improve controllability of a combine harvester, by making the right and left balance of a machine body not change as much as possible even in change of the amount of grain in a grain tank.
Description
The present invention relates to a kind of homework department and the combine that traveling portion can constitute to relative move left and right, at length say it is, can keep the technology that good control feel ground improves left and right sides weight balancing about by Drive Section and running gear are become one.
In the past, disclosed as reaping part and can access and cut and return the combine with the horizontal sliding structure of reaping part (spy opens flat 5-153841 communique etc.) that cuts two states in being suitable for respect to the body move left and right.
In common combine, body left side is provided with threshing portion, and is provided with grain storehouse or pack on the right side of body with grain resettlement sections such as hoppers, therefore, be accompanied by the traveling of harvesting threshing operations, the grain after the threshing stores in the resettlement section, and increase the weight of gradually on the right side of body.Therefore, no matter whether be the combine that reaping part can laterally slide, under the state of fully loaded grain, center of gravity is partial to the right side in the grain resettlement section.Therefore, in the paddy field, often sink to being difficult to rotate, or be difficult to straight line moving etc. performance of running stability is caused harmful effect owing to the crawler belt on right side is serious.
Change even the purpose of this invention is to provide the load of a kind of grain resettlement section, the left and right sides balance of body does not also change as far as possible and improves the combine of maneuvering performance.
In order to reach above-mentioned purpose, combine of the present invention has the traveling portion of crawler belt running gear, Drive Section, engine and has homework department's formation of reaping part, threshing portion, grain resettlement section, it is characterized by, have the relative moving mechanism that the operation support of supporting aforementioned reaping part, threshing portion, grain resettlement section and the traveling support that makes the relative aforementioned traveling of this operation support portion relatively move along the left and right directions of body.
According to such scheme, the adjusting because traveling portion and homework department can relatively move on the left and right directions of body, when making left and right sides changes in balance if increase the weight of the grain resettlement section, traveling portion and homework department can be relative to laterally moving, to absorb its changes in balance, even the grain quantitative changeization of accommodating, about balance also can be maintained at fixed state.
And because Drive Section and traveling portion are one, regardless of laterally moving of homework department, the position relation between Drive Section and crawler belt can not change.For example, the occasion of Drive Section and homework department's one, the grain in the operation traveling in the grain storehouse stores that change is many, and Drive Section also was moved to the left when homework department was moved to the left, and changed with respect to the sight line of field, might produce the illusion of body transversion malposition on the ridge.But, even sight line also can not change because homework department takes place laterally to move among the present invention, operation feeling can be maintained at certain state, be easy to drive.Because engine also is arranged at traveling portion, need not the structure that can laterally move is set in the power train between engine and crawler belt running gear, only such in the past simple structure gets final product in addition.
Thereby, since Drive Section, engine and the incorporate traveling of crawler attachment portion and homework department relative to laterally moving, uncomplicatedization of traveling transmission system can be provided, the relation of Drive Section and traveling occasion can be kept certain and become easy mode of operation, can revise simultaneously and follow operation to carry out so that grain resettlement section side increases the weight of and the left and right sides changes in balance that causes, improve the car body mobile device of performance of running stability and operating characteristics.
On the basis of said structure, in aforementioned grain resettlement section, be provided with the grain amount detecting device that can detect the grain amount that is stored, this grain amount detecting device and relative moving mechanism interrelate, and have following benefit.
Be accompanied by the increase of grain amount, the weight of grain resettlement section strengthens, the left and right sides changes in balance of body.This moment, the grain resettlement section was left by relatively moving with respect to traveling portion by homework department, automatically brought into play the compensation function of left and right sides balance.Therefore, for example, accommodate, also can keep in the threshing operations left and right sides balance become left and right sides balance is equated or make the right side slightly heavily wait decide state.
Also can adopt in the present invention to have and detect the structure that stops the action of aforementioned relative movement mechanism when threshing checkout gear that whether threshing portion move and this threshing portion are failure to actuate.
As has a threshing checkout gear, traveling portion and homework department relatively move, and when moving in threshing portion, promptly reclaim in the threshing operations of grain quantitative changeization and can carry out, on the way reach not variation of grain amount in the wagon box loading and unloading of truck in the traveling, do not relatively move in the time of need not revising left and right sides balance.Promptly have and do not carry out the unnecessary benefit that relatively moves.
Thereby, relatively move the terse combine that does not relatively move when unnecessary in the time of can providing necessary correction left and right sides balance.
If when there was the receipts harvested cereal culm in reaping part, traveling portion and homework department got in touch to become and do not relatively move, owing in the operation traveling of harvesting threshing, do not relatively move, more suitable.In other words, if in the operation traveling, relatively move, when the left and right sides balance of body changes, since its reaction, the necessity that has direction to operate sometimes.When this direction operation, reaping part may shift out beyond the field of plantation paddy stalk, it is not relatively moved can eliminate this possibility.Like this, relatively moving of traveling portion and homework department only limits to by gathering in the ridge to next when not gathering in the headland turn on ridge or use unloader to discharge and carry out when left and right sides changes in balance such as grain does not become problem.
In the present invention, traveling portion and homework department do not relatively move when receiving harvested cereal culm in order to exist at reaping part, can adopt to be provided with in combine and for example can detect the structure that stops the relative moving mechanism action when paddy stalk that has or not the paddy stalk in the reaping part is deposited no sensor and harvested cereal culm is received in existence in this reaping part.
Like this, relatively move in the time of beyond the unquestioned operation traveling of left and right sides changes in balance, can not produce problems such as body relative ridge dislocation.
Aforementioned relative movement mechanism is made of the driver that the operation support that sets up the traveling support that can make traveling portion and homework department relatively moves.
If this driver is made of the oil hydraulic cylinder move left and right of carrying out traveling portion and homework department, two ends piston rod type, have the following advantages.For example the piston two ends are linked to each other respectively with the traveling support with operation support, cylinder tube, can be set to double an one of doing the traveling support by the oil tube, or as reinforcement.Promptly an oil hydraulic cylinder can be brought into play move left and right device and two kinds of functions of support stiffening device.
As mentioned above, the oil hydraulic cylinder that constitutes relative moving mechanism can make the stent reinforcement and the lightweight of traveling portion or homework department, and rational car body mobile device can be provided.
Under the situation that driver is made of oil hydraulic cylinder, the piston of prevention oil hydraulic cylinder and the lockable mechanism that relatively moves between cylinder tube can be set.
In the relative movement device that constitutes by oil hydraulic cylinder, stop under the ground situation that tilts at combine, because the deadweight oil hydraulic cylinder is to the opposite pressure of oil hydraulic circuit effect, might take place because leakage causes the dislocation of traveling portion and homework department to move, or easily from problems such as hermetic unit leakage of oils.Owing to have lockable mechanism, relatively moving between the piston rod of prevention oil hydraulic cylinder and cylinder tube then can stop from the contrary Hair Fixer of oil hydraulic cylinder when making the lockable mechanism action and give birth to effect, eliminated foregoing problems.
Like this, no matter how the residing position of combine tilts, can both prevent to reach the purpose of protection oil hydraulic circuit because the dislocation of traveling portion that leakage causes and homework department is moved or the problems such as leakage of oil of hermetic unit.

Below with reference to the accompanying drawings embodiments of the invention are described.
At first the 1st embodiment of the present invention is described with reference to Fig. 1-Figure 15.
As the vertical view of the end view of the combine of Fig. 1 and Fig. 2 respectively shown in, a is a reaping part, b is a threshing portion, c is the grain resettlement section, 1 be the crawler belt running gear, 2 is Drive Section, 3 is the power part with engine 4 and gearbox 24.
Reaping part a is by pull-up device 5, and reaping apparatus 6 is indulged carrying device 7 compositions such as grade, can be with respect to the body lifting.The b of threshing portion has feeding chain 8, is provided with the drum chamber 10 of threshing cylinder 9, shaker screen screening device 11, and row's straw cutter 12 grades are equipped on the left side of body.Grain resettlement section c discharges outer unloader 14 formations such as grade of machine by the grain storehouse 13 that stores the grain that the b of threshing portion sends here with the grain that reclaim in this grain storehouse 13.
In this combine, has the relative moving mechanism 15 that the A of traveling portion and the B of homework department can be relatively moved and regulate at the left and right directions of body.Wherein the A of traveling portion has crawler belt running gear 1, Drive Section 2 and power part 3, and homework department has reaping part a, the b of threshing portion and grain resettlement section c.
As Fig. 1, Fig. 4-shown in Figure 6, the A of traveling portion is by having sprocket wheel 16, the left and right sides turning rack 19 of regulating wheel 17 and a plurality of driven pulley 18,19, support the traveling chassis 21 of above-mentioned member and carry to support the Drive Section 2 and the traveling support 27 of power part 3 to constitute by elevating mechanism 20.
As Fig. 1, Fig. 4, Fig. 5 and shown in Figure 7, the B of homework department is propped up to be held in by lift-launchs such as reaping part a, the b of threshing portion, grain storehouse 13, fuel tanks 26 and constitutes on the operation support 25, and can support glidingly on left and right directions with respect to traveling support 27 by the mounted tracks structure.
And, relate to the traveling support 27 of the A of traveling portion and the operation support 25 of the B of homework department, forwardly reach the rear portion and set up oil hydraulic cylinder (one of driver example) 22,23.
Piston rod 23A is passed by the two ends of the tubular cylinder tube 23a of back oil hydraulic cylinder 23, and the two ends of piston rod 23A are connected in the left and right end portions at operation support 25 rear portions.Tubular cylinder tube 23a double as be about link the member of traveling support 27.After this oil hydraulic cylinder 23 short preceding oil hydraulic cylinders 22 also are that its piston rod 22A is passed by the two ends of tubular cylinder tube 22a, and the two ends of piston rod 22A are connected in the left and right end portions of operation support 25 front portions.Cylinder tube 22a is fixed on the traveling support 27.
As shown in Figure 8,4 piston rod 22A, 23A are connected by elastomer connector F with operation support 25.Elastomer connector F is made of the substrate 50,51 of rubber section 51 with its two ends, and a side substrate 50 is fixed in the end of piston rod 22A, 23A, and the opposing party's substrate 50 is fixed on the operation support 25.
The piston rod 22A of each oil hydraulic cylinder, 23A since will form the 22b of grease chamber, 23b about hold bar 22c, 23c to be connected by tube connector 22d, 23d and to form strip.
By regulating, make outstanding length increase and decrease by piston rod 22A, 23A outstanding about cylinder tube 22a, 23a by the action oil supply amount of solenoid electric valve 38 (Figure 15) the subtend 22b of grease chamber, 23b.At this, because each outer end of piston rod 22A, 23A is fixed on the operation support 25 by elastomer connector, therefore the total length of each oil hydraulic cylinder 22,23 is certain, when the overhang increase and decrease of piston rod 22A, 23A, produces between piston rod 22A, 23A and cylinder tube 22a, the 23a and relatively moves.Because cylinder tube 22a, 23a be fixed on the traveling support 27 of the A of traveling portion side, the piston rod 22A, the 23A that are fixed on the operation support 25 of the B of homework department side are relatively moved to the left and right directions of body by cylinder tube 22a, 23a.Therefore, operation support 25 can horizontally slip in deciding scope with respect to traveling support 27.
The right plate 13a in the overhang of direction and grain storehouse 13 is from overhang about equally the state of right-hand track chiain 1R to right left from left crawler belt 1L for the left plate 28 that Fig. 3 (a) shows the b of threshing portion, and promptly the B of homework department is quantitative by the horizontal to the left and right side-prominent institute of the A of traveling portion quantitative standards.Fig. 3 (b) show the B of homework department thus the relative traveling A of portion of standard move to the final shift position in left side that has the opposition side of side as the grain resettlement section.Between normal place and shift position, can the B of mobile operating portion and the relative moving mechanism 15 of the relative position of the A of traveling portion constitute by the oil hydraulic cylinder 22,23 of front and back.The action equal in length of displacement between normal place and the shift position and oil hydraulic cylinder 22,23.
When relative moving mechanism 15 was made of oil hydraulic cylinder, because the A of traveling portion is only taken on by oil hydraulic cylinder 22,23 with the left and right sides determining positions of the B of homework department, occurrence positions was offset bit by bit when oil leaks.At this,, be provided with and limit the combining mechanism H that traveling support 27 and operation support 25 relatively move as Fig. 5, Fig. 6 and Fig. 9-shown in Figure 11.The acting as of this combining mechanism H make A of traveling portion and the B of homework department be in fixed relative adjustment position.Operation support 25 mountings relatively move by the rolling of roller 52 with respect to the rolling surface 53 of operation bracket side on a plurality of oblique rollers 52 of being installed on the traveling support 27.And, being positioned at least significant (aforesaid standards position) in grain storehouse 13 and forming recess 53a, 53a with 2 places that are positioned at leftmost position (aforementioned shift position), roller 52 enters among this recess 53a, the 53a.Owing to constitute combining mechanism H by roller 52 with recess 53a like this, on two positions of aforesaid normal place and shift position, even cause the location function of oil hydraulic cylinder 22,23 incomplete owing to leak to wait, by the action of combining mechanism H, the relative position skew of a of traveling portion and the b of homework department roughly can not take place yet.Moreover, can provide resistance to laterally moving of a of traveling portion and the b of homework department by combining mechanism H, oil hydraulic cylinder 22,23 and combining mechanism H both sides' effect is arranged on the fixed adjusting position, can roughly not have offset movement ground with a of traveling portion and the b of homework department stop.
Combining of the present invention mechanism has control device 37 as shown in figure 15, and control device 37 has for making relative moving mechanism 15 move the control loop that carries out various controls.Control device 37 has for making the B of homework department move the slide control device C that grain amount detecting device and relative moving mechanism 15 are connected to the left with respect to the A of traveling portion according to the grain amount increase that stores in the grain storehouse 13, and switch the automatic mode of this slide control device C action and by workman's operation to the relatively move mode-changeover device 39 of manual operation mode of adjusting of the A of traveling portion and the B of homework department.In control device 37, also be provided with the weight meter (example of grain amount detecting device) 41 that can detect the grain amount that stores in the grain storehouse 13.
In control device 37, the solenoid electric valve 38, mode selector switch 39 that is connected with the action oil mass that the 22b of grease chamber, the 23b that regulate oil hydraulic cylinder 22,23 forwards, backwards supply with and the move left and right action bars 40 of operation solenoid electric valve 39 usefulness and be arranged on the weight meter 41 of 13 bottoms, grain storehouse.Automatic control by slide control device C, weight meter 41 detected weight (during no grain) when the lightest, homework department places by the rightest normal place, weight meter 41 detected weight (grain full load) when the heaviest, and the B of homework department places and leans on the most left shift position.And under the situation of the fully loaded grain when this shift position in the grain storehouse 13, set left and right directions weight balancing in case about crawler belt running gear 1,1 on effect about equally weight is arranged.
When mode selector switch 39 switched on " automatically ", above-mentioned slide control device C action was automatically laterally slided according to the grain amount B of homework department that reclaims in the grain storehouse 13.Actual slip is only moved at strain root switch 46 and direction switch 47 (both are the paddy stalk and deposit a not example of sensor) when being all OFF, promptly there is not conveyance paddy stalk in vertical carrying device 7 parts, when not gathering in object paddy stalk simultaneously (the back half of headland turn for example, during to the ridge, during the mobile traveling of interblock) carry out.
After this as clutch switch that to make the detection threshing b of portion described later be driving condition 45 when switching to ON by OFF but, slide control device C becomes operating state, and this moment, the B of homework department laterally slid into the corresponding position of the grain amount of storing with grain storehouse 13.When clutch switch 45 switched to OFF by ON, slide control device C became non-action state, and for example the B of homework department is back to automatically near the rightest normal place (receiving state).The condition that is the move left and right of car body is that threshing switch 45 is ON, and the root of strain simultaneously switch 46 is OFF.
As previously discussed,, do not need, make operation simple by correction guarantees this unnecessary operation of straight line moving to the caused lateral shake travel direction of horizontal mobile inertia because it is mobile not slide in the operation traveling.In addition, the automatic direction control of conduct of working is known technology, Therefore, omited detailed description thereof with the direction switch 47 of sensor to the root that is arranged at the strain root switch 46 on vertical carrying device 7 and is arranged at the careless tool 48 of branch with planting that upright paddy stalk contacts.
When mode selector switch 39 switches on " manually ", can operate solenoid electric valve 38 by the operation of move left and right action bars 40, can the horizontal arbitrarily B of mobile operating portion.Be that the B of homework department accompanys or follow the operating position of move left and right action bars 40 and moves, when left and right sides action bars 40 being operated among Figure 15 the rightmost side, move to normal place, move to the shift position when being operated to the leftmost side.As shown in Figure 5, detect moving of back oil hydraulic cylinder 23 by the stroke sensor 49 that constitutes by linear potentiometer etc., with the B of homework department with respect to the position, the left and right sides of the A of traveling portion to control device 37 feedbacks.
Move left and right action bars 40 is not limited to form shown in Figure 15, for example also can constitute central authorities for neutral, the B of homework department is moved to the left when toppling over left, the move left and right action bars 40 of the connection that moves right when toppling over to the right, disconnect type, by making left and right sides action bars turn back to neutrality after operation is moved relative moving mechanism 15, the B of homework department can be placed desired position by toppling over of left and right sides action bars.
Usage as the manual control pattern, be to consider for example when selecting automatic control mode, the B of homework department relies on the right side before the harvesting threshing operations begins, but when the occasion in the narrow place by overhanging projection is arranged, mode selector switch 39 is placed " manually ", so that the B of homework department is moved to the left and can passes through.
In this combine, have whether the threshing of the detection b of portion is the threshing checkout gear 42 of driving condition.Threshing control device D is arranged in the control device 37, slide control device C and mode selector switch 39 and threshing checkout gear 42 are got in touch and are become, when having selected the state of automatic control mode, slide control device C can move when the b of threshing portion moves, and, slide control device C akinesia when the b of threshing portion is failure to actuate.
Threshing checkout gear 42 by threshing clutch (not shown) is connected, clutch switch 45 formations of the threshing clutch lever 44 of opening operation and this lever position action during for " connections ".When mode selector switch 39 is switched the occasion that is operated to " automatically ", it is when clutch switch 45 action during for " connections " that slide control device C is controlled so as to, and is failure to actuate when clutch switch 45 is " disconnection ".
This combine also is provided with and detects body traveling whether traveling checkout gear 43.Traveling control device E is arranged in the control device 37, getting in touch between mode selector switch 39 and traveling checkout gear 43 and the relative moving mechanism 15 becomes, when being chosen as the manual control pattern, the action of relative moving mechanism 15 is only can carry out when body stops traveling.
Promptly, speedometer 43a as traveling checkout gear 43 is connected on the control device 37, at mode selector switch 39 handover operations is " manually ", when the detection speed of speedometer 43a is zero (or utmost point low speed is following), use move left and right action bars 40 can carry out the manual operation that the B of homework department laterally moves, but the non-vanishing occasion (or occasion higher) of detection speed than extremely low speed as speedometer 43a, equal solenoid electric valve 38 and be locked in the neutral position, even operation move left and right action bars 40, relative moving mechanism 15 is not moved yet.
The action of relevant decision slide control device C, the key element of non-action can be strain root switch 46 only also, are ON as strain root switch 46, and A of traveling portion and the B of homework department can not relatively move, and strain root switch 46 is OFF, and A of traveling portion and the B of homework department can relatively move.In view of the above, be at the edge of a field in the traveling of harvesting threshing operations and the laggard line slip of harvesting end is moved.
The action of decision slide control device C, the key element of non-action can only be clutch switch 45 also, are ON as clutch switch 45, and A of traveling portion and the B of homework department can relatively move, and clutch switch 45 is OFF, and A of traveling portion and the B of homework department can not relatively move.In view of the above, for the slip mobile status, be the mobile status of not sliding in the mobile traveling in the traveling of harvesting threshing operations.For example the plot is harder, and some slips of the B of homework department are moved under the situations such as influencing the direction operation hardly effective in the operation traveling.
For the control of moving of the B of homework department with respect to the A of traveling portion, can consider to be set at increase according to the grain amount (or weight) that reclaims to grain storehouse 13, homework department is moved to the left, perhaps be set at the B of mobile operating portion so that about the load of crawler belt running gear 1,1 often keep the various schemes of phase or the like.In addition, also can slide the B of homework department mobile arbitrarily by manual operation.
Slidably homework department normal place shown in Figure 3 and shift position also can be set shown in Figure 12 and 13 like that.
Shown in Figure 12 (b), right plate 13a (with reference to the double dot dash line among Figure 12 (a)) is from the overhang of right-hand track chiain 1R about equally to the overhang of right and the machine in the past that relative moving mechanism 15 will be set from right-hand track chiain 1R for the right plate 13a that also can be set at grain storehouse 13 on the shift position.In this occasion, shown in Figure 12 (a), grain storehouse 13 is compared aforesaid machine in the past to the overhang of right and is wanted significantly on normal place, but be the state of sky in the storehouse in the case, with the deterioration so of balance about the occasion of machine was compared in the past.The example of Figure 12 is specially adapted to have the combine in big capacity grain storehouse.
As shown in figure 13, the right plate 13a in grain storehouse 13 is become by slide construction etc. can be to right-hand structure of stretching out displacement.It is the most inboard to be retracted into body as Figure 13 (a) normal place right plate 13a that is shown in.Grain storehouse 13 is for stretching out most when the shift position shown in Figure 13 (b), but the set positions of the right plate 13a of this moment is identical when becoming with normal place.
Like this, right plate 13a also can be got in touch with respect to the left/right movement device (not shown) of grain storehouse 13 body move left and right and front and back oil hydraulic cylinder 22,23 to be become: right plate 13a for the position of the left and right directions of the A of traveling portion no matter the B of homework department whether slide mobile, on the position when all being maintained at normal place.
For the driver that constitutes relative moving mechanism 15 also can Figure 14 (a) and (b), structure shown in (c) replaces oil hydraulic cylinder 22,23.
Shown in Figure 14 (a), can adopt electromotor 29 and the relative transverse moving mechanism 15 of feed screw mechanism 30 as the electronic housing structure of driver, this electronic cylinder body 15 be arranged at position of centre of gravity on the left and right directions of the B of homework department under near, move efficiently with minimum power.
Shown in Figure 14 (b), also can by the steel wire 31 that is connected in operation support 25 left and right sides, by the pars intermedia of the left and right directions of this steel wire 31 reel a circle roller 32, be installed on drive motors 33 on the traveling support 27 and constitute relative moving mechanism 15 (driver).In this example, drive motors 33 also be arranged on position of centre of gravity on the left and right directions of the B of homework department under better.

Brake seat 55 supportings brake cam 57 free to rotate is erect with stationary state simultaneously and is supported steady pin 58.Brake seat 55 is embedded on the outside of cylinder tube 23a and fixes by bolt etc.A pair of brake(-holder) block 54,54 is applied in pulling force by spring 60, and this spring 60 clips brake(-holder) block 54 and is provided with each a pair of 4 altogether the both sides of steady pin side and brake cam side.
Oval-shaped cam 57 and brake(-holder) block 54 become parallel contactless state (Figure 19 (a)) by pressure surface 54b the time, effect by 4 springs 60, a pair of brake(-holder) block lining 54a, 54a contact with the periphery of piston rod 23A is powerful, become the lockup state that stops piston rod 23A and cylinder tube 22a to relatively move.
When the locking state shown in Figure 19 (a), in case geared dynamo 56 is connected, owing to overcome the elastic force of spring 60, cam 57 rotates, a pair of brake(-holder) block 54,54 is expanded to the external diameter direction, cut-out brake(-holder) block lining 54a, 54a contact with piston rod 23A periphery, become the releasing lockup state, become the state (state of Figure 19 (b)) that allows piston rod 23A and cylinder tube 22a to relatively move.
In the 2nd embodiment, as shown in figure 20, promising driving relative moving mechanism 15 is set and the control loop that carries out various controls.At this, omit the explanation part identical with the 1st embodiment.
Be connected with the ignition switch 61 of geared dynamo 56 and engine 4 on the control device 37, engine 4 becomes oil hydraulic cylinder 23 free-moving locking disarm states automatically when turn state; When engine 4 stops, becoming automatically and can not carry out relatively moving of piston rod 23A and cylinder tube 23a, that is to say the lockup state that relatively moves of A of traveling portion and the B of homework department.Be that lockable mechanism R constitutes under non-action status and to stop relatively moving of piston rod 23A and cylinder tube 23a, the anti-brake that relatively moves (non-action status of lockable mechanism and the on-position of brake are corresponding) of permission piston rod 23A and cylinder tube 23a under operating state.
56 of aforesaid gears driving motors are arranged on the long oil cylinder 23 in the oil hydraulic cylinder 22,23 and only at the end of cylinder tube 23a.In Figure 18 as only be conceived to half one that geared dynamo 56 1 sides are arranged of oil cylinder 23, on operation support 25, be provided with and detect oil hydraulic cylinder 23 maximums and stretch out the shortest sense switch 63 that the maximum of state (the piston rod 23A of Figure 18 upside is outstanding to greatest extent state) is stretched out sense switch 62 and can be detected maximum indentation state (state that this piston rod 23A returns to greatest extent) here.These switches 62,63 by with control device 37 connect can with warning device 68 interlock mutually.By be installed on cylinder tube 23a on action movie 64 contact, when the B of homework department is positioned at close the most left shift position with respect to the A of traveling portion, be that maximum is stretched out sense switch 62 and is ON, when the shortest sense switch 63 is the OFF state simultaneously, engine 4 stops, send attentions such as " car body is in slip " electronics sound or alarm tone by alarm device 68, report the operator and be in sliding mode.(with reference to Figure 20).
As will being in this shift position state and the shortest sense switch 63 is ON, the maximum simultaneously switch that stretches out is that the indicator lamp of normal place state by console panel etc. of OFF represented to the operator, can confirm the moving state of car body expediently.
For example, the harvesting threshing operations finishes, and when buy securities with all one's capital in grain storehouse 13, the B of homework department is under the state that moves left the position most and is shifted out by the plot, and combine temporarily stops under this state.After this waiting during mobile traveling once again, the B of homework department is still in the shift position, is when turning round again in normal place if operator's this moment takes for, the body left end just might with wall etc. on every side object contact.In order to prevent the generation of this type of state of affairs, stopping during shutting engine down and want traveling again and when making ignition switch 61 become ON, can send aforementioned signal the operator is noted will be very convenient.
In addition, even when mode selector switch 39 is positioned at " automatically " pattern, if also can send warning when engine 4 stops under being in the shift position state, therefore be under the state of shift position by unloader 14 paddy is discharged after, when engine is restarted, can identify the B of homework department in advance and will be immediately suit to the normal place this point of laterally sliding.In this occasion, alarm device 68 becomes confirms that cross-car moves the monitor of usefulness.
Figure 21 and Figure 22 show the variation of the 2nd embodiment.In this variation, lockable mechanism R is made of the cover member.
On the piston rod side substrate 50 of each elastomer connector F of the left and right sides of oil hydraulic cylinder 23 piston rod leading section, the piston rod cover that section is the U font (example of cover member) 66 with pivotal support at fulcrum P.From fulcrum P with this piston rod cover 66 when piston rod side is swung, can embed between the cylinder tube end face 22e of piston rod side substrate 50 and piston rod side, so that it is under reach to stop oil hydraulic cylinder 23 to carry out.The side-to-side dimensions of piston rod cover 66 is set and is embedded for this reason and can only carry out when the maximum of oil hydraulic cylinder 23 is stretched out state.
Cylinder tube side at piston rod cover 66 is connected with action bars 67.The common position that the inner slide that cylinder tube 23a can enter piston rod cover body 66 of showing Figure 21 (b), Figure 22 (b) moves.When this common position, oil hydraulic cylinder 23 is for stretching out most state.At this moment as operating operation bar 67, be pressed into piston rod cover 66, the cover end 66a of oil hydraulic cylinder side embeds with lucky and the tight contact condition of cylinder tube end face 22a, so oil hydraulic cylinder 23 by locking, can not carry out under reach.
Because on the piston rod 23A of this piston rod cover 66 about being installed in respectively, can stop relatively moving of on 2 positions of normal place and the shift position A of traveling portion and the B of homework department.We can say that piston rod cover 66 is to constitute lockable mechanism R as the brake of stop on maximum elongation and the shortest 2 positions, to stop moving of oil hydraulic cylinder 23.
