Below, with reference to accompanying drawing embodiments of the invention are described.
Fig. 1 represents the combination machine as an example of harvesting machine.This All-China Federation of Taiwan Compatriots closes on the traveling machine body 2 of track unit 1R, the 1L of reaper about having sheller unit 3, Drive Section 4 etc. is being set, and being provided with in the front portion of traveling machine body 2 can be round the transverse axis axle center X harvesting homework department 5 of lifting and swinging freely.
Above-mentioned harvesting homework department 5 is by the crop stem (the stem stalk part of plant) of plantation is propped up into it reciprocating type reaping apparatus 7 of holding up ground device 6, the root of the stem stalk of being propped up being cut off of orthostatism, the stem stalk of cutting off that is orthostatism is altered to gradually vertical feedway 8 formations of the threshing feeding chain belt 3a top portion on the sheller unit 3 that the accumbency posture also is transported to the back simultaneously as the harvesting object.And harvesting homework department 5 makes freely to drive lifting with oil cylinder 9 by the lifting as the descending operation structure.
Whether in the conveying top of above-mentioned vertical feedway 8 one root sensor SO (example of harvesting operating condition detecting device) is being set, being detected by it has the stem stalk of cutting off carrying.
As shown in Figure 2, the walking driving system of body is to give transmission gearbox 12 transmission of power of driving engine 10 by transmission system 11, steering clutch 13R, 13L about being provided with in transmission gearbox 12 supply with left and right sides track unit 1R, 1L to power respectively by them.And be that operation according to the shifter bar that there is not expression among the figure makes transmission system 11 speed changes, set the body speed of travel thus, simultaneously by its to about the intermittent operation of steering clutch 13R, 13L carry out the steering operation of body.
Below, the operating structure of above-mentioned each steering clutch 13R, 13L is described.Each steering clutch 13R, 13L carry out intermittent operation respectively by oil cylinder 14R, 14L, and each oil cylinder 14R, 14L carry out oil pressure control respectively by the conversion operations of solenoid electric valve 15.And on moving transfer part 4, be provided with and can freely carrying out the control lever 16 (referring to Fig. 3) that cross shakes operation respectively towards body fore-and-aft direction and left and right directions, according to the operation of the left and right directions of control lever 16 above-mentioned solenoid electric valve 15 is carried out blocked operation.Promptly, as shown in Figure 3, when this is got back to control lever 16 on the center position towards the left and right sides any one direction shake, thereby when pole changer 17R, 17L are connected, the control mechanism 18 as control setup that is provided with microcomputer is just controlled solenoid electric valve 15, corresponding steering clutch 13R, 13L are changed, the walking of turning thus.
Below, the control structure in the descending operation that gathers in homework department 5 is described.
Above-mentioned lifting is carried out conversion and control with the solenoid electric valve 19 that oil cylinder 9 works by above-mentioned control mechanism 18, can carry out descending operation according to the action of the fore-and-aft direction of control lever 16.Promptly, when make aforesaid operations bar 16 from center position when the body fore-and-aft direction shakes, make decline switch 20 connect or make 21 connections of rising switch, when decline switch 20 is connected, 19 inputs of 18 pairs of solenoid electric valves of control mechanism descend and use control signal, when rising switch 21 was connected, 19 inputs of 18 pairs of solenoid electric valves of control mechanism were risen and are used control signal.
Like this, above-mentioned control lever 16 is equivalent to hand-operated lifting with indicating device (perhaps hand-operated lifting command device), by means of this control lever 16 is rocked back and forth, can manually be adjusted to the lifting position of harvesting homework department 5 on the optional position.
At the upper face of the handle 16a of aforesaid operations bar 16 automatic lifting switch SW as the lifting finger showing device is being set, this automatic lifting switch SW is by constituting with the button switch that thumb is operated.And above-mentioned control mechanism 18 is to make the state that is in connection as root sensor SO, promptly begin in that time detecting the time that is transformed into off-state (non-operating condition) by the harvesting operating condition through time of setting, when operating above-mentioned automatic lifting switch SW, can make harvesting homework department 5 automatically rise to the target hoisting position; After this, when operation automatic lifting switch SW, just make harvesting homework department 5 automatic lowerings carry out to the decline target location that lifting controls.
Lifting and swinging fulcrum location in harvesting homework department 5 is being provided with the lifting position sensor 22 of potentiometer type, it is the relative pendulum angle that detects with respect to traveling machine body, promptly detects the relative lifting position of the relative body of harvesting homework department 5.
Below, with reference to the control flow chart of Fig. 4 and the sequential chart of Fig. 5, the control action of the 1st embodiment of the present invention is described.
When root sensor SO connected and gathers in operation, automatic lifting control was stopped, even at this moment operation automatic lifting switch SW can not be carried out automatic lifting (step 1,2); Read in by the aviation value (promptly gathering in the operation center-line-average) of above-mentioned lifting position sensor 22 detected detected values (lifting position), every section setting-up time of computing, stored (step 3,4) then.
In gathering in operation, the ON Action that makes decline switch 20 or rising switch 21 that forms by means of the action of the front and back of control lever 16 is the height adjustment that gathers in homework department 5 and maintain on the suitable harvesting operation height.
And the harvesting end of job of working as this operation process, root sensor SO converts disconnection to from connection, from this conversion the time be carved into through setting-up time t (for example 5 seconds) during this period of time in, during operation automatic lifting switch SW, 19 outputs of 18 pairs of solenoid electric valves of control mechanism are risen with control signal (step 5～6).Shown in " P " in Fig. 5, in the present embodiment, when the automatic lifting switch SW is connected,, also can implement to go up automatically lift operations even the height and position of harvesting homework department is between decline object height and the climbing target height.
In this case, the descending operation of harvesting homework department 5 just carries out descending operation according to the ON Action of rising switch 21 or decline switch 20.
Then, decline switch 20 or rising switch 21 disconnected, if the instruction that does not have hand-operated lifting to use, then gather in homework department 5 according to the detection information of lifting position sensor 22, rise to upper limit position as the climbing target position.And when harvesting homework department 5 arrives above-mentioned upper limit position, stop to rise and use the output of control signal, make vertical motion stop (step 6～9).
After this, decline switch 20 or rising switch 21 are disconnected, to the initial end of gathering in the operation process next time, operate the automatic lifting switch SW once more, at this moment if gather in homework department 5 at upper limit position or near this position, control mechanism 18 just output decline is used control signal, makes harvesting homework department 5 drop to the last one time harvesting job position that is storing as mentioned above.And when harvesting homework department 5 arrives the lower position, stop to descend and use the output of control signal, thereby make down maneuver stop (step 10～16).
In step 12, if harvesting homework department 5 does not then carry out step-down operation and just turns back to step 1 not at upper limit position or not near this position.
Whether harvesting homework department 5 is in upper limit position or near this position, this is to be determined by the detected value of at that time lifting position sensor 22 and the deviation of detected value that is equivalent to the lifting position sensor 22 of upper limit position, when this deviation below setting value, then be judged as at upper limit position or near upper limit position.And whether harvesting homework department 5 is in as the harvesting operation height of decline target location or near this height, this is to be determined by the detected value of at that time lifting position sensor 22 and the deviation of above-mentioned aviation value (aviation value of harvesting height), when this deviation is in setting value, then is judged as and is in the harvesting operation height or near this height.
Like this, the operation of the automatic lifting switch SW that just can be finished by the simple motion of the sort of press operation that press...withes one's finger just can alternately be carried out rising to the vertical motion of upper limit position and the down maneuver from the upper limit position automatic lowering to the harvesting job position automatically from the harvesting job position automatically.
In addition, operate the operation of descend switch 20 or 21 connections of rising switch according to rocking back and forth of control lever 16, promptly, if the decline instruction (Fig. 4 is expression decline switch 20 operated situations) that has climb command that vertical motion uses or down maneuver to use, at this moment then stop above-mentioned automatic lifting control, according to the making operation of decline switch 20 or rising switch 21, carry out hand-operated lifting control ( step 7,10,14,17,18).That is, the operation of control lever 16 is carried out than automatic lifting operator precedence.
Like this, after stopping according to the making operation of decline switch 20 or rising switch 21, by the control of hand-operated lifting operation handlebar automatic lifting,, turn back to step 1 even operation automatic lifting switch SW can not be carried out lifting action (with reference to the some Ω of Fig. 5); From root sensor SO judge from connection be transformed into be carved into when open circuited through the time t that setting during this period of time in, if operation automatic lifting switch SW just can be carried out by automatic lifting and control the automatic vertical motion that forms.
Like this, after connecting decline switch 20 or rising switch 21, convert to during this period of time open circuitedly from connection to root sensor SO judgement, become and forbid automatic lifting operating period, in during this, stop automatic lifting control according to automatic lifting indication (instruction).
If it is longer that non-operating condition continues, even operation by the automatic lifting indicating device, harvesting homework department 5 is risen to when walking under the sort of state of upper limit position, also might make and gather in homework department's 5 execution down maneuvers because of by mistake operating the automatic lifting indicating device.Because when this operation with the automatic lifting switch SW of generation is mistaken, might cause with operator's wish makes harvesting homework department 5 carry out the improper of automatic lifting operation mutually on the contrary, thereby, make control mechanism 18 not carry out controlling according to the automatic lifting of automatic lifting switch SW at this moment by cutting off automatic transfer switch 23.
The 2nd embodiment
Before end is faced in the harvesting operation, with manual mode lift operations is gone up in order to avoid obstacle such as ridge by harvesting homework department 5 and when gathering in operation, have when harvesting homework department 5 has risen on the harvesting job position of regulation, needn't carry out going up automatically the situation of lift operations to harvesting homework department 5 according to the operation of the SW of automatic lifting indicating mechanism.Like this, when the harvesting end of job, when harvesting homework department 5 is in the midway location (between lower limit target location and the upper limit target location) of range,, can make following structures to jacking system for automatic lifting indicating mechanism is failure to actuate.
Promptly make and make the harvesting end of job of operation process, converting root sensor SO to disconnection from connection, from this conversion the time be carved into through setting-up time t (for example 5 seconds) following period of time, operation automatic lifting switch SW, have only when harvesting homework department 5 to be on the harvesting operation height or near this height the time, control mechanism 18 just to solenoid electric valve 19 outputs rise and use control signals.The same with the above embodiments, whether harvesting homework department 5 is in as the harvesting height of decline target location or in its vicinity, be to judge by the detected value of at that time lifting position sensor 22 and the deviation of above-mentioned aviation value (aviation value of harvesting operation height), when this deviation in setting value, then be judged as harvesting homework department 5 and be near harvesting operation height or this height.
The operation order of the jacking system in this structure as shown in Figure 6 and Figure 7.
Represent to be clear that after the diagram of circuit of the 1st embodiment operation order is compared with Fig. 4, in the operation order of the jacking system of the 2nd embodiment, be between the step 5 of the diagram of circuit (Fig. 4) of the 1st embodiment and step 6, to have added to confirm whether harvesting homework department 5 is in the step (step 6) of Fig. 6 on the harvesting job position.According to this additional step, if the height of the reaping part 5 during operation automatic lifting switch SW is when being in the also high position of harvested position than regulation, harvesting homework department 5 to be risen automatically.Therefore, when being judged as " No ", do not carry out the automatic lifting operation in step 6.And when only being judged as " Yes " in step 6, just enter step 7 and gather in homework department 5 go up lift operations automatically, just carry out identical order after this with above-mentioned the 1st embodiment.Here, for fear of the explanation that repeats, step 6 the following description has been omitted.
Can know by " R " of the sequential chart of Fig. 7 and to find out, press the form of present embodiment, in the setting-up time t after the harvesting operation is ended, if operation automatic lifting switch SW, the height and position of harvesting homework department 5 does not at that time just carry out the automatic lifting operation if be on the midway location of lower limit target location and upper limit target location.
Like this, if harvesting homework department 5 does not just carry out by the formed automatic vertical motion of the operation of automatic lifting switch SW not near harvesting operation height or this height; If harvesting homework department 5 is not near upper limit position or this position, do not carry out the automatic lowering action that the operation by the automatic lifting switch SW forms yet, just can prevent from thus to gather in homework department 5 under the state of the midway location of range, towards the direction automatic lifting opposite with operator's wish.
The 3rd embodiment
Control setup can also be made following structure, promptly in the final stage of gathering in flow chart, run into non-operation location and be under the narrow situation, for avoiding contacting with obstacles such as field bunds, not only after the harvesting end of job of a stroke, can operate the automatic lifting switch SW and carry out automatic lifting, and carry out also carrying out automatic lifting in the process in the harvesting operation.
Below, the operation order of the jacking system of the control mechanism 18 with this structure is described with reference to Fig. 8 and Fig. 9.
A bit different except having with above-mentioned the 2nd embodiment, that is, to carry out also operating the automatic lifting switch SW under the state that root sensor SO is switched on beyond this point of automatic lifting, this operation order is identical with the order of above-mentioned the 2nd embodiment basically.Promptly in step 2～4 of Fig. 8, represented to be under the on-state (promptly at the harvesting operating condition) order during operation automatic lifting switch SW at root sensor SO.
In step 1, when root sensor SO is on-state, then transfer to step 2 and step 3, read in the data of the lifting position of harvesting homework department 5, detect the harvesting height mean place under this harvesting operating condition.This with the 1st and the 2nd embodiment in step 2,3 identical.Then, in step 4, when connecting, the automatic lifting switch SW then transfers to next step 6, in the lower position (promptly whether the position of judgement harvesting homework department 5 at this moment, scope at the harvesting job position), if it is the setting range of harvesting job position, then next step 7 gather in homework department 5 automatically on lift operations.Certainly, can omit step 6 here, that is, even output per litre can not gone up at harvesting job position (being the lower position) by harvesting homework department 5 yet.Following step is all identical with the foregoing description, thereby the repetitive description thereof will be omitted.
Below, with reference to the sequential chart of Fig. 9 above-mentioned this operating state is described, especially to note with " S " mark represent that part of.Promptly in the above-described embodiment, be under the on-state at root sensor SO, do not carry out the operation of automatic lifting switch SW, present embodiment then with the actuating wire of root sensor SO be in on-state irrespectively, in operating time by the automatic lifting switch SW shown in " S ", the actuating wire of last output per litre becomes on-state.And, by that part of actuating wire of the lifting position in the operating time that is illustrated in the automatic lifting switch SW shown in " S " to upper right lifting, the jacking condition of this expression harvesting homework department 5.
Like this, even root sensor SO is under on-state, when harvesting homework department 5 is in the harvesting job position, also can carry out the automatic lifting operation.
The 4th embodiment
The common ground of the foregoing description be in the automatic lifting operation the automatic lowering operation carry out state.Promptly, the form of above-mentioned all embodiment all is an operation automatic lifting switch SW, satisfy under the situation of rated condition in the transfer time of root sensor SO and/or the harvested position of harvesting homework department 5, after harvesting homework department 5 rises automatically, carry out the automatic lowering operation.Also have, even with the operation of automatic lifting switch, make after harvesting homework department 5 arrives upper limit positions, to next operation automatic lifting switch SW during this period of time in, if the operation of hand-operated lifting bar 16 is arranged, the automatic lowering operation of harvesting homework department 5 just is cancelled.
Promptly, for harvesting homework department 5 is carried out the automatic lowering operation, must satisfy on carrying out automatically after the lift operations, hand-operated lifting bar 16 condition such as be failure to actuate, on the smooth ground that operating environment less changes, perhaps be out of question when carrying out identical harvesting operation repeatedly, but consider under another kind of operating environment, can carry out the automatic lowering operation when also wishing the condition beyond satisfying the foregoing description.
Present embodiment then is at this point, makes and can carry out automatic lowering operation when meeting the following conditions.That is, harvesting homework department 5 by operation automatic lifting switch SW, just can carry out automatic lowering to harvesting homework department 5 and operate at upper limit position (perhaps climbing target position) or near this position the time.That is,, all can carry out the automatic lowering operation no matter whether carried out going up automatically lift operations in advance.
Below, with reference to the control flow chart of Figure 10,10A and 10B, illustrate that the control action that automatic lifting is controlled is carried out in the instruction according to the automatic lifting switch SW of present embodiment.

At first, whether the operation condition of judging automatic lifting control sets up (step 1).
Promptly, the engine revolution that threshing switch 25 connecting (another form of implementation of above-mentioned operating condition detecting device), detected by tachometer generator 24 is more than the revolution (for example 500rpm) of regulation, if and the output of lifting position sensor 22 output normal value, the operation condition that then is judged as automatic lifting control is set up.Wherein, can set another more suitable value for as the above-mentioned engine revolution of the operation condition of automatic lifting control.
And even also can make under non-operating condition, the operation condition of automatic lifting control is also set up.
If above-mentioned operation condition is set up, when then providing the automatic lifting instruction by the automatic lifting switch SW, if by the detected value of lifting position sensor 22 learn the harvesting homework department 5 lifting position be in the climbing target position or near this position (as an example, get from upper limit position 150mm with interior position), the sign ( step 2,3,4) that descends then is set.
Then, when root sensor SO is on-state, perhaps the harvesting end of job, the root sensor SO at certain operation stroke converts disconnection to from connection, is carved into this following period of time through setting-up time t (for example 4 seconds) when this changes, and the sign (step 5,6) that rises is set.
And, if the sign that rises is set, just goes up output per litre and handle, if the sign that descends is set, (step 7～10) are handled in the output that then descends.
Shown in Figure 10 A, it is to make the lifting position of harvesting homework department 5 rise to predefined height (for example in upper limit position 15mm) that last output per litre is handled, perhaps make output time abovely arrive the rising screw actuator with signal output, carry out automatic vertical motion rising through the predefined time (for example 3 seconds).That is, when lifting position rises to predefined height (for example in upper limit position 15mm), perhaps when output time when the predefined time, (for example 3 seconds) were above, will rise indicates removing (step 81～84).
Shown in Figure 10 B, it is to make the lifting position of harvesting homework department 5 drop to predefined height (for example below upper limit position 450mm) that the output that descends is handled, perhaps make output time abovely arrive the decline screw actuator with signal output, carry out the automatic lowering action descending through the predefined time (for example 2 seconds).That is, preestablish height (for example below the 450mm) when lifting position drops to from upper limit position, perhaps output time passed through when the predefined time, (for example 2 seconds) were above, and the sign that will descend is removed (step 100～103).
Even carrying out according to from the automatic rising control of the automatic climb command of automatic lifting switch SW or carrying out in the process of automatic lowering control, when manual lever 16 is shaken any direction of operating the body fore-and-aft direction from center position, decline switch 20 or rising switch 21 connected when providing the hand-operated lifting instruction thus (during step 11), also can make the control of automatic rising control or automatic lowering stop to carry out, the rise sign or the sign that descends are removed (step 12), thus preferentially carry out manually going up lift operations or manually step-down operation according to the making operation of decline switch 20 or rising switch 21.
