At this moment, described speed change detecting sensor 113 can be used the potential measurement instrument (potential meter) that can detect foot-operated HST pedal 110 swing offsets and pressure sensor etc.Certainly, can utilize the RPM detecting sensor that detects the engine revolution in addition.
At this, described foot-operated HST pedal 110 can constitute when stepping on first half accelerations that realize advancing as shown in Figure 9, step on and realize the rear acceleration when latter half of, perhaps constitutes the special structure of advancing, retreat pedal is set respectively.This speed changing structure that is made of pedal and linkage belongs to the well-known technology in this area and related industry field, can select to adopt the bar linkage structure of various ways by various equivalent modifications, so it is not defined as ad hoc structure in this specification.
Aforesaid saddle type rice transplanter provided by the present invention can have the various work patterns that utilize touch type action bars 140 and foot-operated HST pedal 110, roughly may be defined as three kinds of following work patterns.At first, input rice transplanting clutch made the action of rice transplanting pincers when first work pattern was 200 declines of rice transplanting homework department, and hydrostatic formula drives the pattern of advancing and carrying out the rice transplanting operation by foot-operated HST pedal 110.Secondly, second work pattern is that rice transplanting homework department 200 realizes the advance pattern of the edge of a field cycle action of turning to of steering wheel 120, foot-operated HST pedal 110 when rising.Secondly, turning to of steering wheel 120 roughly kept the craspedodrome state when the 3rd operation pattern was 200 declines of rice transplanting homework department, and hydrostatic formula drives the pattern of slowly travelling or keeping halted state.
Below with reference to Figure 10 a to Figure 10 c rice transplanting homework department 200 control logics that are used to carry out this rice transplanting work pattern are described.
Figure 10 a to Figure 10 c is the flow chart of rice transplanting homework department control logic in the expression saddle type rice transplanter provided by the present invention, though its content with korean patent application 10-2004-0075790 number is identical, but, in explanation of the present invention, it is quoted for the The whole control logic of the saddle type rice transplanter that the embodiment of the invention provides is described.
Described control logic realizes by the control program of being imported in the microcomputer of automaton inside that is installed in instrument board or driver's seat below usually.
For ease of understanding, the implication represented such as " switch " on the description of flow diagram or " sensor " at first.
At first, " rising switch " is connected switch when upwards side direction is operated with described touch type action bars 140, described rice transplanting homework department rise (below, the last side direction operation table of touch type action bars is shown the connection of " rising switch ") when this switch is switched on.
Secondly, " decline switch " is connected switch during with the downward side directions operation of described touch type action bars 140, described rice transplanting homework department descend (below, the lower side of touch type action bars is shown the connection of " decline switch " to operation table) when this switch is switched on.
Then, whether " kickboard sensor " is and the sensor of the adjacent layout of described kickboard of rice transplanting homework department lower end, is used to detect kickboard and contacts with ground.
That is, the signal value of described kickboard sensor reaches to set value and represents that the rice transplanting homework department that comprises kickboard contacts with ground.
Then, " upper limit limit switch " is the switch with the adjacent layout of trailing wheel protective plate at the described main part rear of travelling, and is used to detect described rice transplanting homework department and whether arrives upper limit position.
That is, this switch is switched on expression rice transplanting homework department and rises to upper limit position.
Then, " HST pedal sensor " as previously mentioned, be arranged on the speed change checkout gear that travels of foot-operated HST pedal 110 bottoms, function with the speed change state of travelling that detects saddle type rice transplanter self, playing will advance to travel or retreat whether to travel about the lifting control of rice transplanting homework department notifies the effect of described automaton.
Below, describe each flow chart in detail.
Figure 10 a is the flow chart about the decline control logic, each step of the down maneuver of expression control rice transplanting homework department.
At first, on the flow chart " automatic/hand selector switch ' ON '? " step is " automatically " or " manually " the whether step on the described rice transplanting of the affirmation homework department control model, if the affirmation result is a "Yes", the control model of then described rice transplanting homework department is " automatically ", if instead the affirmation result is a "No", then its control model is " manually ".
Shown in flow chart, under described automatic/hand selector switch is connected to the state of " automatically ", if the operating personnel pushes described " decline " switch, then rice transplanting homework department is along with the energising of decline solenoid (solenoid), and continuing to descend reaches setting value (ooze surface in contact water) up to described kickboard sensor.
It should be noted that at this, if more than described " decline " switch press certain hour (being exemplified as " 0.5 second " on the flow chart), then singly not that rice transplanting homework department descends, the rice transplanting clutch is connected when down maneuver takes place, and its result can directly carry out the rice transplanting operation in rice transplanting homework department kiss the earth.
This is one of feature of the present invention, can be described as the preferred control form of the intention that begins operation rapidly that can realize the operating personnel very effectively.
And, as previously mentioned, if because of operating personnel's error or mechanical breakdown etc., more than " decline " switch connection certain hour (being exemplified as " 5 seconds " on the flow chart), then described automaton stops the further decline of rice transplanting homework department by the "on" position of removing the decline solenoid.
If the manual control model of flow chart the right expression, the lasting decline till the operating personnel no longer pushes " decline " switch of then described rice transplanting homework department.
In described manual control model, even consider that ignoring rice transplanting homework department has contacted ooze surface in the water and continued to make the action of decline solenoid, can not cause factors such as saddle type rice transplanter breakage yet, therefore can be as the "on" position of described automatic control mode compulsory commutation decline solenoid.
Certainly, even as described automatic control mode, adopt the control logic of the "on" position of compulsory commutation decline solenoid when " decline " switch connection certain hour (for example, " 5 seconds ") is above also harmless.
Figure 10 b is the flow chart about the rising control logic, each step of the vertical motion of expression control rice transplanting homework department.
On the flow chart " automatic/hand selector switch ' ON '? " implication in the decline control logic of the implication that step had and described Figure 10 a is identical.
Shown in flow chart, under described automatic/hand selector switch is pushed state into " automatically ", if the operating personnel operates described " rising " switch, then rice transplanting homework department is along with the energising of rising solenoid, and the described upper limit limit switch that continues to rise on the trailing wheel protective plate is switched on.
In addition, when rising rice transplanting homework department, at first disconnect the rice transplanting clutch to cut off the power that is delivered to rice transplanting homework department fully.
Thereupon, have as a kind of rice transplanting clutch lamp (lamp) of concentrator marker function and lighted.
Identical with described decline control logic, if because of operating personnel's error or mechanical breakdown etc., more than " rising " switch connection certain hour (being exemplified as " 5 seconds " on the flow chart), then described automaton stops the further rising of rice transplanting homework department by the "on" position of compulsory commutation rising solenoid.
The manual control model that is illustrated in the flow chart left side is identical with described automatic control mode, this be for no matter control model automatically, the whether manual serious damage that can both effectively prevent the saddle type rice transplanter that the excessive rising because of rice transplanting homework department causes.
In the rising control logic, difference between automatic control mode and the manual control model is: in automatic control mode, discern the ceiling of described rice transplanting homework department by described upper limit limit switch, and in manual control model, the ceiling of described rice transplanting homework department is given the operating personnel and is judged.
Figure 10 c is for about retreating the flow chart of rising control logic, each step of control rice transplanting homework department vertical motion when being illustrated in the main part that travels and retreating.
On the flow chart " automatic/hand selector switch ' ON '? " the implication that step had is identical with rising control logic and the implication in the decline control logic of described Figure 10 a and Figure 10 b.
Shown in flow chart, under described automatic/hand selector switch is connected to the state of " automatically ", if the operating personnel steps on the position of drawing back with described HST gear shift pedal, then in the alarm tone that sounds, rice transplanting homework department rises along with the energising of rising solenoid, and the described upper limit limit switch on the trailing wheel protective plate is switched on.
That is, impaired in order to prevent rice transplanting homework department because of retreating of the main part that travels, when described HST gear shift pedal is placed in going-back position, rice transplanting homework department is risen overally.
But, owing to also carry out the situation of special operation when existing rice transplanting homework department to retreat by ooze surface in the smooth water of described kickboard etc., therefore tackle this situation, connecting at described automatic/hand selector switch is the state of " manually ", promptly under manual control model, when retreating, do not export the main part that travels alarm tone, the rice transplanting homework department of yet not rising yet.
That is to say that under manual control model, the operating personnel can determine seedling-transplanting device portion whether to rise according to different situations at least.
Those skilled in the art can carry out various modifications and changes to the present invention with above-mentioned structure and effect according to aforesaid various embodiment.Thus, the content that the technical scope of reality of the present invention should not be defined as in the specification to be put down in writing, and should determine by claims.
