Description
The present invention relates to a kind of threshing grader, comprising: one side swings up and down the swing sorting plate of the handled thing after the threshing of one side sorting process; Detect the bed thickness testing agency of the bed thickness of the handled thing on the above-mentioned swing sorting plate; Change the aperture change mechanism of the aperture of leaking down of above-mentioned swing sorting plate; Control the control device that above-mentioned aperture changes mechanism.
In above-mentioned handled thing layer thickness detection apparatus, bed thickness testing agency is for example by being supported in the fuselage rear with pivot freely with the swing of sagging posture and being configured in the rodmeter of swing sorting plate top and this rodmeter being contacted with handled thing and bed thickness sensor that the angular transition of swinging to the fuselage rear becomes the potential difference meter of bed thickness value to form constitutes, and the bed thickness detected value of bed thickness sensor changes in time owing to swing swinging up and down of sorting plate, therefore to sample to its bed thickness detected value by reasonable time interval (for example 100ms), differentiate as the bed thickness value with the moving average of its a plurality of data.
Also have, in threshing grader, bed thickness according to above-mentioned differentiation detects the aperture of leaking down that the swing sorting plate is regulated in information (for example information of bed thickness detected value and rate of change thereof) change, so that make the bed thickness of the handled thing on the swing sorting plate be in optimum range, prevent that whereby crossing when thin the straw slag at above-mentioned handled thing layer sneaks in 1 thing, otherwise and when above-mentioned handled thing floor is blocked up 3 losses increase and 2 undue shortcomings such as grain damage (opening flat 5-21 communique) that cause that increase of the amounts of returning referring to for example spy of Japan.
In above-mentioned technology in the past, if the handled thing bed thickness of swing on the sorting plate changes when slow in time, then the bed thickness value of obtaining according to moving average and the difference of actual bed thickness can be ignored.But the handled thing bed thickness of swing on the sorting plate changes when increasing in time, and then the bed thickness value of obtaining according to above-mentioned rolling average increases with the difference of actual bed thickness, especially can not correctly detect the variation of its bed thickness.Therefore, swing the adjusting control that the adjusting of the aperture of leaking down of sorting plate neither be correct according to this bed thickness detection information, cause the handled thing bed thickness on the swing sorting plate to break away from optimum range greatly, might take place because the adverse consequences that aforementioned processing thing layer is blocked up or thin excessively situation causes.
The present invention proposes in view of above-mentioned truth, and its purpose is, more correctly detects the bed thickness of the handled thing on the swing sorting plate that swings up and down, thereby detects the aperture adjusting etc. of leaking down that information is correctly swung sorting plate according to this bed thickness.
The threshing grader that utilizes the present invention to make comprises: one side swings up and down the swing sorting plate of the handled thing after the threshing of one side sorting process; Detect the bed thickness testing agency of the bed thickness of the handled thing on the above-mentioned swing sorting plate; Change the aperture change mechanism of the aperture of leaking down of above-mentioned swing sorting plate; Control the control device that above-mentioned aperture changes mechanism;
Above-mentioned control device comprises the bed thickness mechanism for identifying of differentiating the bed thickness of above-mentioned handled thing according to the detection information of above-mentioned bed thickness testing agency.
Above-mentioned bed thickness mechanism for identifying is taked the detection information of above-mentioned bed thickness testing agency according to the sampling period shorter than the hunting period of above-mentioned swing sorting plate, and, above-mentioned bed thickness mechanism for identifying carries out the bed thickness of above-mentioned handled thing and differentiates for setting for and synperiodic each cycle of above-mentioned swing sorting plate according to the sampled data of taking in its processing cycle.
When employing has the structure of such characteristics, handled thing after the threshing of swing on the sorting plate swings up and down along with swinging up and down of sorting plate of swing, and the detection information that is arranged at the bed thickness testing agency on the fixed mount for the bed thickness that detects its handled thing is according to changing the hunting period of above-mentioned swing sorting plate.Like this, according to taking than hunting period in the short sampling period of swing sorting plate after the bed thickness detection information of above-mentioned cyclical swing, for setting and swing synperiodic each cycle of sorting plate for, according to the sampled data of in its processing cycle, taking, for example differentiate the bed thickness of handled thing according to the mean value of its sampled data.According to above processing, can remove the influence that swings up and down information that bed thickness is detected of swing sorting plate, and obtain the just detection information of the bed thickness of handled thing.
Therefore, by removing the influence that swings up and down of swing sorting plate, the bed thickness of the handled thing on the swing sorting plate that can more correctly swing up and down detects, thereby can detect the aperture adjusting etc. of leaking down that information is correctly swung sorting plate according to its bed thickness.
In preferred example of the present invention, have for setting for and swing synperiodic each cycle of sorting plate, differentiate the practice of the bed thickness of handled thing according to the mean value of the maximum of the sampled data of in its processing cycle, taking and minimum of a value.When taking this approach, to average the bed thickness of differentiating handled thing in the maximum and the minimum of a value of the sampled data in the processing cycle, therefore, for example compare with the practice that above-mentioned sampled data is all averaged the bed thickness of differentiating handled thing, not only guarantee the bed thickness accuracy of detection in the practicality, Processing Structure is simplified.
In another preferred example of the present invention, have leak down from the threshing cylinder chamber handled thing amount detection machine structure of the handled thing amount to above-mentioned swing sorting plate of detection, and,
For the bed thickness that makes above-mentioned handled thing is in the zone of reasonableness, above-mentioned control device is according to operational ton control aperture change mechanism, and this operational ton is according to the information decision of the bed thickness detected value of above-mentioned bed thickness testing agency and rate of change and above-mentioned handled thing amount detection machine structure, at this moment, under the identical situation of above-mentioned bed thickness detected value and rate of change thereof, above-mentioned control device makes above-mentioned handled thing amount more strengthen the aforesaid operations amount for a long time than above-mentioned handled thing amount after a little while.
When utilization has the structure of these characteristics, leaking down by drum chamber after a little while to the amount of swinging the handled thing on the sorting plate, than the operational ton that leaks down by drum chamber and more strengthen for a long time to the amount of the handled thing of swing on the sorting plate that bed thickness detected value and rate of change thereof according to the handled thing layer determined, and can change the aperture of regulating the swing sorting plate according to its bigger operational ton in order to the aperture of leaking down of change swing sorting plate.Therefore, because it is few to the amount of swinging the handled thing on the sorting plate to leak down from drum chamber, adapt therewith, in the aperture of leaking down that will swing sorting plate during to the state of closing direction (little direction) operation, for example supply with the fixed handled thing piece that forms such as grain or the grain of band sprig stalk etc. by drum chamber, they stop up the portion of leaking down that is trapped in the swing sorting plate, thereby the bed thickness value of handled thing sharply increases or its increasing rate when becoming big, the aperture of leaking down that sorting plate is swung in the operation more promptly that will adapt therewith makes it change to opening direction (big direction); On the other hand, handled thing piece that causes above-mentioned delay state etc. is removed rapidly from its delay state, the bed thickness value of handled thing sharply reduces or its slip when becoming big, and the aperture of leaking down of the sorting plate of operation swing more promptly that adapt therewith makes it change to closing direction (little direction).
In another preferred example of the present invention, aforementioned control device (H) has the main aperture control program (Le-チ Application) and auxiliary aperture control program of different control cycles for aforementioned aperture change mechanism (M1), when breaking away from optimum range, the bed thickness of above-mentioned handled thing reaches setting value when above, or the bed thickness of above-mentioned handled thing is when changing by the rate of change more than the setting rate, can select above-mentioned auxiliary aperture control program.
If adopt structure with these characteristics, the bed thickness of the handled thing on the swing sorting plate breaks away from optimum range, less than setting value and its bed thickness rate of change during less than the setting rate, for example consider in the required time of the alter operation of the aperture of leaking down of swing sorting plate etc., can change the aperture of leaking down of regulating the swing sorting plate according to above-mentioned bed thickness detection information with regulation control cycle by long time set.On the other hand, when the bed thickness of the handled thing of swing on the sorting plate break away from optimum range reach more than the setting value or its bed thickness rate of change when the setting rate is above, can change the aperture of leaking down of regulating the swing sorting plate according to above-mentioned bed thickness detection information with the control cycle shorter than afore mentioned rules control cycle.
Therefore, change at the bed thickness of the handled thing of swing on the sorting plate little, under the more stable situation of bed thickness detected value, the aperture of leaking down of the change swing sorting plate that should do one's utmost to avoid unnecessary; On the other hand, change under the rapid situation at bed thickness, swing the aperture change of leaking down of sorting plate with the short cycle, so that can be adapted to the bed thickness of its handled thing rightly changes, therefore, for example with no matter the size that above-mentioned bed thickness changes is all carried out above-mentioned control by certain cycle compares, the bed thickness that can do one's utmost to keep the handled thing layer on the swing sorting plate is in optimum range and carry out appropriate sorting process.

Utilize above-mentioned control device H, constitute the bed thickness mechanism for identifying 100 of differentiation aforementioned processing thing bed thickness according to the detection information of aforesaid bed thickness sensor S1.This bed thickness mechanism for identifying 100 is according to than the sampling period (for example 5ms) of lacking with the hunting period (for example 125ms) of the detected swing sorting plate 19 of aforementioned speed probe S7 the detection information of bed thickness sensor S1 being sampled, and, for the hunting period of setting and swinging sorting plate 19 in synperiodic each cycle, carry out the bed thickness of aforementioned processing thing according to the sampled data that in its processing cycle, is extracted and differentiate.Specifically, be exactly with the mean value of the maximum of the sampled data of aforementioned processing in the cycle and minimum of a value bed thickness as the aforementioned processing thing.
For the bed thickness that makes the aforementioned processing thing is in the suitable scope, aforementioned control device H changes the aperture control of the aperture of leaking down of regulating aforementioned swing sorting plate 19 according to the information control cycle according to the rules of aforementioned bed thickness mechanism for identifying 100.Simultaneously, the bed thickness of aforementioned processing thing breaks away from optimum range and reaches setting value when above, or the bed thickness of aforementioned processing thing is when changing by the rate of change more than the setting rate, assist aperture control, i.e. the aperture of leaking down that swing sorting plate 19 is regulated in the short control cycle change of aforementioned regulation control cycle according to than aforementioned aperture control the time.Specifically, shown in Figure 27 (a), the deviation of (left part among the figure) and above-mentioned bed thickness is between big setting value S2 and little setting value S1 and its rate of change (the right side part among the figure) when setting rate Δ S is above carries out above-mentioned auxiliary aperture and controls when the big setting value S2 of deviation in the setting value of 2 sections of sizes of the bed thickness detected value that departs from suitable bed thickness scope S0 is above.In addition, example illustrates the variation of carrying out the clever shell aperture before and after the above-mentioned auxiliary aperture control in Figure 27 (b).Be used for regulation control cycle that the aperture of leaking down of the swing sorting plate 19 when the control of above-mentioned aperture regulates and set aforesaid 2 times of return (for example 3 seconds) on sorting unit B for.Control cycle during above-mentioned auxiliary aperture control set for basically can be considered as continuous control short period (as described later, 250ms).
In addition, aforementioned control device H makes when carrying out aforementioned aperture control and assisting aperture control, the operational ton that is determined according to bed thickness detected value and rate of change thereof according to aforementioned bed thickness sensor S1 makes aforementioned sieve electromotor M1 action, thereby the change of carrying out aforementioned clever shell aperture is regulated.Also have, as described later, windmill electromotor M2 also moves according to the actuating quantity of above-mentioned sieve electromotor M1.Specifically, control device H is constructed as follows: will ask in advance to count in according to fuzzy deduction and state the operational ton data that operational ton draws and store as numerical tabular, promptly select the data in the above-mentioned numerical tabular to decide the aforementioned operation amount according to its operational ton data, and among 2 control laws (2 numerical tabulars) of when its fuzzy deduction, selecting to set 1, and then obtain aforementioned operation amount data corresponding to the size of the aperture of leaking down of swing sorting plate 19 according to aforementioned clever shell aperture.Also have, control device H obtains the desired value of clever shell aperture and windmill rotating speed according to the operational ton of above-mentioned decision, and each desired value is become zero with the Deviation Control of the detected value of clever shell jaw opening sensor S2 or windmill speed probe S3.Be illustrated with regard to the control law in the aforementioned fuzzy deduction below.As the array element of fuzzy graph shown in Figure 24, can obtain as bed thickness detected value (connotation is identical with the screening measured value) with respect to bed thickness deviation of the deviation of the bed thickness desired value (connotation is identical with the sieve mesh scale value) of handled thing (connotation is identical with the sieve deviation) and bed thickness variable quantity (connotation is identical with the sieve variable quantity) as the variable quantity of the bed thickness detected value in the stipulated time.At this, if the bed thickness detected value when bigger, then sieve than bed thickness desired value deviation on the occasion of; Otherwise, then be negative value.Have, the bed thickness detected value has when increasing tendency again, the sieve variable quantity be on the occasion of; Having when reducing to be inclined to, then is negative value.Under the little situation of clever shell opening ratio regulation aperture (for example 19mm), the master map (Figure 24 (a)) among 2 fuzzy graphs selecting to be prepared; Under than the big situation of regulation aperture, select auxiliary view (Figure 24 (b)), according to above-mentioned sieve deviation and the fuzzy deduction of sieve variable quantity as the fuzzy variable of independent variable (former piece portion), asking gets it right promptly sieves the output of electromotor M1 in the operational ton of clever shell aperture.Promptly, the sieve deviation is subordinate to (membership) function as Figure 23 (a) and (b) with the sieve variable quantity, fuzzy variable as the dependent variable (consequent portion) of rule shown in Figure 24, the membership function of operational ton that is clever shell aperture shows as discrete monodrome (シ Application グ Le ト Application) set shown in Figure 23 (c).Respectively scheme one or more rules among shown 25 rules from Figure 24, the grade (グ レ-De) (being also referred to as the goodness of fit (grade of fit)) of each membership function according to sieve deviation and sieve variable quantity can obtain output, and the resulting value of smaller value that the output that draws from the rule that is fit to be multiply by among the grade of sieve deviation or sieve variable quantity promptly becomes the output that obtains from its rule.Draw from a plurality of rules under the situation of a plurality of outputs, with their mean value as final output.Also have, above-mentioned output also is to represent with positive and negative 8 bit digital value, on the occasion of expression clever shell aperture is operated to the direction that increases, and negative value is represented clever shell aperture to the direction operation that reduces.By above-mentioned control law (Figure 24) also as can be known, selected master map (Figure 24 (a)) stipulates that with clever shell opening ratio selected auxiliary view (Figure 24 (b)) compares under the big situation of aperture under the little situation of clever shell opening ratio regulation aperture, and the operational ton of clever shell aperture strengthens.Particularly under the sieve deviation condition all big with sieving variable quantity, clever shell aperture is set at bigger operational ton.Therefore swing the aperture hour of leaking down of sorting plate 19 and will strengthen the operational ton that bed thickness detected value and rate of change thereof according to bed thickness sensor S1 are determined when bigger than the aperture of leaking down of swing sorting plate 19.
Below, utilize the flow process of the threshing control that control device H carries out according to Fig. 7～flowchart text shown in Figure 22.In main flow chart (Fig. 7), at first, after carrying out the initial setting processing, carry out the setting processing that processing and conventional data are surveyed in screening, the screening survey is handled for the bed thickness detection data of utilizing bed thickness sensor S1 to obtain and is handled.Then, after the mark or counter O reset with each control usefulness when threshing switch SW 1 off-state, check the self diagnosis processing that sensor class and each one are unusual.On the other hand, when threshing switch SW 1 is transformed into the on-state threshing operations and is begun by off-state, carry out threshing control according to the control cycle (250ms) of each regulation and handle.Thereafter, carrying out above-mentioned self diagnosis handles.
When initial setting is handled (Fig. 8), check whether the data of the fully open position that is stored in the glume-shell screen 24 in the memory (EEPROM) and full close position are normal.If normal, according to these data set for respectively the upper limit position that clever shell aperture is regulated be positioned at than the fully open position of above-mentioned data a little by closing the position of side; Make the lower position be positioned at than the full close position of above-mentioned data a little by opening the position of side.In addition, when only the difference in upper limit position and lower position is bigger than setting (suitable aperture amount), upper limit position is reset and on the lower position, add the resulting position of its setting (suitable aperture amount).On the other hand, if when the data of fully open position of glume-shell screen 24 in the memory (EEPROM) and full close position are undesired (for example all being 0) then as abnormality processing.
Survey handling for screening is that bed thickness detects and handle (Fig. 9～Figure 11), to the sampling period (5ms) according to the rules the detected value of bed thickness sensor S1 be sampled, just detect the used processing time (setting 125ms for) of its minimum of a value and maximum the most at the beginning, above-mentioned sampled data is stored as minimum of a value and maximum value data.After, upgrade processing in turn, last till through the above-mentioned processing time (125ms) always, promptly, upgrade the minimum of a value data by its detected value when the detected value of the bed thickness sensor S1 that takes during less than the minimum of a value data; When detected value during, upgrade maximum value data by its detected value greater than maximum value data.Through above-mentioned processing time when (125ms), obtain the mean value of minimum of a value and maximum value data, and obtain this mean value and the mean value in preceding 1 processing time and W.Then, carry out (after promptly passing through 250ms) after the above-mentioned processing of secondary, for the bed thickness data of storing each processing time respectively are up-to-date screening measured value, screening measured value before the 250ms and the screening measured value before the 500ms, with regard to 250ms data (2), the 250ms data (1) and 250ms data (0) that are provided with in the memory, the memory contents of 250ms data (2) and 250ms data (1) will be transferred to respectively in 250ms data (1) and the 250ms data (0), be that up-to-date screening measured value stores in the 250ms data (2) with above-mentioned that try to achieve and 1/2 of W simultaneously.Thereby, by above processing, having constituted aforesaid bed thickness mechanism for identifying 100, the processing cycle of its bed thickness differentiation usefulness is corresponding with the above-mentioned processing time (125ms).
Then, the sieve deviation is obtained as the predefined sieve mesh scale value and the difference of up-to-date screening measured value (contents of above-mentioned 250ms data (2)), will be sieved differential value (variable quantity) and obtain as the difference of screening measured value before the 500ms (contents of above-mentioned 250ms data (0)) and up-to-date screening measured value (contents of above-mentioned 250ms data (2)).Also have, above-mentioned sieve mesh scale value becomes different values by each crop conversion condition enactment of wheat described later and rice.Such (referring to Figure 27) as described above, when the bigger setting value among the sieve deviation is being set 2 sections setting value of size for is above and the sieve deviation between bigger setting value and less setting value and the sieve differential value when setting value (corresponding with the setting rate) is above, make permission continuously (in fact control cycle is 250ms) carry out in principle permitting the mark connection with the continuous control that the threshing control of carrying out at interval in 3 seconds is handled.On the other hand, during situation beyond above-mentioned, continuous control permission mark is disconnected.
Then, up-to-date screening measured value (contents of above-mentioned 250ms data (2)) is divided into 5 sections sieve values, promptly rises and be divided into 0,1,2,3,4 grade in turn by the little person of detected value.Then, have only the different state of sieve Value Data in sieve value that ought above-mentionedly be divided into grade and the memory that stores former sieve value to continue continuously with the control cycle of 250ms under the situation of 5 times (in other words 250ms * 4=1 more than second) at least, just the usefulness sieve value of newly trying to achieve is upgraded above-mentioned sieve Value Data.
Set processing (Figure 12) for conventional data, only when the detected value of aforementioned windmill adjusting potentiometer VR surpassed the dead band width than the variation of storing the windmill potentiometer data value in its detection memory of data, its detected value just upgraded as the value in the windmill potentiometer data.Next, check the state of aforementioned crop change-over switch SW2, according to wheat, rice and moisteningly respectively shift one's position, make pattern (mode) value be respectively 0,1,2.Having, is that aforementioned sieve value is 0 and 1 o'clock under wheat and rice pattern again, and as described later, sieve value 0 usefulness that aperture is set usefulness is set with the minimum aperture of clever shell of sieve value 1 usefulness respectively.
Handle (Figure 13) for threshing control, at first judge the crop condition, when moistening pattern, carry out moistening pattern control (Figure 14) according to pattern (mode) value.On the other hand, when wheat and rice pattern, as described below, according to the state of strain root sensor S4 and the content of aforementioned sieve value, carry out speed of a motor vehicle induction type control (Figure 15) and fuzzy control (Figure 16 and Figure 17), speed of a motor vehicle induction type is controlled under the situation that bed thickness sensor S1 breaks down and regulates clever shell aperture and windmill wind-force according to the speed of a motor vehicle; Fuzzy control is to regulate according to the clever shell aperture that fuzzy rule carries out.Then, the sieve electromotor M1 and the clever shell output of windmill electromotor M2 action are handled and windmill output processing according to the above-mentioned adjusting actuating quantity that sets when respectively controlling.
In other words, when wheat and rice pattern, when strain root sensor S4 is in on-state, its by disconnect to change become connection after during through the stipulated time (6 seconds), mark set in 6 seconds (this 6 seconds marks reset when strain root sensor S4 becomes off-state), on the other hand, when strain root sensor S4 is in off-state, after it is transformed into disconnection by connection, be that aforementioned sieve value in the time of 8 seconds, makes mark set in 8 seconds (this 8 seconds marks reset when strain root sensor S4 becomes on-state) at 0 state continuance.Then, check whether the detected value of bed thickness sensor S1 is normal, for example, because causes such as broken strings, detected value is 0 volt or is equivalent to supply voltage value etc., when being judged as the fault of bed thickness sensor S1 therefrom, carries out the control of speed of a motor vehicle induction type.If bed thickness sensor S1 is normal, during through the control cycle (3 seconds) of regulation, though and when not passing through the aforementioned continuous control permission of control cycle (3 seconds) mark and connecting, carry out fuzzy control.
For moistening pattern control (Figure 14), the desired value of clever shell aperture is set in fully open position, go out the windmill rotating speed according to aforementioned windmill potentiometer data computation.In other words, when windmill adjusting potentiometer VR was in normal place, the windmill rotating speed was rated rotational frequency (for example 1300rpm); When turning to strong side or weak side along with windmill adjusting potentiometer VR by normal place, the windmill rotating speed is converted to high-speed side or low speed side by above-mentioned rated rotational frequency.Then, when its windmill rotating speed of calculating is lower than windmill minimum speed (for example 1000rpm), with its minimum speed as the windmill rotating speed of target; When being higher than windmill maximum speed (for example 1500rpm), with its maximum speed as the windmill rotating speed of target; In the time of between above-mentioned windmill minimum speed and windmill maximum speed, with the windmill rotating speed of calculating as the windmill rotating speed of target.
For speed of a motor vehicle induction type control (Figure 15), at first, the speed of a motor vehicle for example is divided into 0～0.35m/s, 0.35～0.55m/s, 0.55～0.75m/s, 0.75～0.95m/s, 0.95m/s～5 section, according to for the calculating chart of the pre-prepd speed of a motor vehicle of this each section of speed of a motor vehicle to clever shell aperture, as shown in figure 26, obtain clever shell aperture desired value respectively by wheat, rice pattern.Then, handle (Figure 18 and Figure 19), calculate the windmill rotating speed of target according to above-mentioned clever shell aperture desired value by windmill speed setting described later.
For fuzzy control (Figure 16 and Figure 17), obtain screening measured value (contents of above-mentioned 250ms data (2)) for the sieve deviation of the deviation of sieve mesh scale value and up-to-date screening measured value (contents of above-mentioned 250ms data (2)) sieve variable quantity, as the array element of fuzzy graph for the variable quantity of the screening measured value before the 500ms (contents of above-mentioned 250ms data (0)).Then, such as described above, under the situation of clever shell aperture at that time, according to master map (Figure 24 (a)) less than regulation aperture (19mm); Under situation,,, obtain output for sieve electromotor M1 according to above-mentioned sieve deviation and the fuzzy deduction of sieve variable quantity as the fuzzy variable of independent variable according to auxiliary view (Figure 24 (b)) greater than the regulation aperture.
Then, check the state of strain root sensor S4, when it was in on-state, clever shell aperture at that time added that the above-mentioned operational ton of obtaining is exactly clever shell aperture desired value.Have again, be under the situation of set at aforementioned 6 seconds marks, be after strain root sensor S4 connects during through 6 seconds, identical with aforementioned speed of a motor vehicle induction type control, the speed of a motor vehicle is divided into 5 sections, obtain the minimum aperture of clever shell according to pre-prepd figure with respect to each speed of a motor vehicle stage, when above-mentioned clever shell aperture desired value during less than the minimum aperture of its clever shell, with the minimum aperture of its clever shell as clever shell aperture desired value.
On the other hand, when strain root sensor S4 is in off-state, for forbid to clever shell aperture open side change, checks above-mentioned operational ton of trying to achieve whether be on the occasion of, be on the occasion of the time to make operational ton be zero.Have again, when aforementioned 8 seconds marks are under the situation of set, after promptly strain root sensor S4 becomes disconnection by connection, during aforementioned sieve value 0 state continuance to 8 second, with the minimum aperture of clever shell of clever shell aperture desired value as sieve value 0 usefulness of aforementioned setting.Under the situation that 8 seconds marks reset, the sieve value is when (0 and 1) below 1, and with the clever shell minimum aperture of clever shell aperture desired value as sieve value 1 usefulness of aforementioned setting, the sieve value is more than 2 when (2,3,4), with clever shell aperture desired value as at that time clever shell aperture.Then, according to the clever shell aperture of above-mentioned each of trying to achieve desired value, handle (Figure 18 and Figure 19) by windmill speed setting described later and calculate the windmill rotating speed of target.
Handle (Figure 18 and Figure 19) for the windmill speed setting, utilize the straight line transform to calculate the windmill rotating speed with respect to clever shell opening value, wheat pattern when as shown in figure 25, this calculating is to use and regulates potentiometer VR and be in normal place about aforementioned windmill and the transform of rice pattern.Also has the minimum speed t that sets the windmill rotating speed accordingly with the full cut-off side and the standard-sized sheet side of clever shell aperture
MinWith maximum speed t
Max' as a reference,, also express the transform when windmill regulated potentiometer VR and turn to strong side or 1 scale of weak side by normal place for the rice pattern.Next, when the windmill rotating speed that aforementioned calculation draws is lower than aforesaid windmill minimum speed (1000rpm), with its minimum speed as the windmill rotating speed of target; When being higher than windmill maximum speed (1500rpm), with its maximum speed as the windmill rotating speed of target.Thereafter, the position of regulating potentiometer VR according to aforementioned windmill is carried out the increase and decrease of windmill rotating speed of target and is proofreaied and correct, and the rotating speed after it is proofreaied and correct is lower than to be regulated potentiometer VR with windmill and carry out above-mentioned minimum speed t in after changing the transform
MinThe time, with its minimum speed t
MinAs the windmill rotating speed of target; When being higher than maximum speed t
MaxThe time, with its maximum speed t
MaxAs the windmill rotating speed of target.
