Based on Fig. 4 mechanism is sowed to liquid and actuating unit is described.
Cantilever 3 arranges the flexible pipe 18 of liquid of supply spray tank 2, arrange in the way of flexible pipe 18 conveying liquid prevent and kill off pump 19, adjust flux flow control valve 20, select cantilever 3a, right cantilever 3b left whether respectively, hand spray valve 21(left cantilever spray valve 21a, right cantilever spray valve 21b, central cantilever spray valve 21c that central cantilever 3c supplies liquid).The power of engine 6 from power shaft 22 via gear 23 to running gear output shaft 24, prevent and kill off pump output shaft 25 and export.
Based on Fig. 8, operation board 11 is described.
Operation board 11 possesses the operation tool of the action of sowing of liquid and cantilever 3.The left and right directions action of setting operation cantilever 3 and the cantilever actuating strut 26(left cantilever actuating strut 26a of above-below direction action and right cantilever actuating strut 26b).In addition, the folding and unfolding posture of changing left cantilever is set and sows the left cantilever posture changing bar 27a of posture, be similarly provided with right cantilever posture changing bar 27b and change the cantilever posture changing bar 27c of posture of left cantilever and right cantilever simultaneously.
In addition, setting operation sows the spray valve 21(left cantilever spray valve 21a of liquid or stopping, central cantilever spray valve 21c and right cantilever spray valve 21b from cantilever 3).In addition, the amount of the sowing configuration switch 29 of the display meter 28 of the display amount of sowing and the increase and decrease of the setting amount of sowing is set.In addition, arrange: make to prevent and kill off the switch pump 30 that pump 19 is ONOFF; Describe in detail later, the driving vehicle 1 sowed in operation is when carrying out revolution action, automatically carry out making the cantilever 3(outside revolution being in the present embodiment left cantilever 3a) carry out the automatic lifting gauge tap 31 of the control of lifting action; And the left and right posture of driving vehicle 1 tilts also can carry out the automatic horizontal gauge tap 32 cantilever 3 being maintained the control of flat-hand position or approximate horizontal posture.
Sow the basic traveling of vehicle based on the liquid of Fig. 5 ~ Fig. 7 to present embodiment and sow action and be described.
Operator is seated at driver seat 10, and ato unit 6 starts to travel.When entering farmland and operate cantilever posture changing bar 27c, the cantilever travelling the left and right of posture is expanded to the left and right sides of driving vehicle 1, becomes and sows posture.Automatic lifting gauge tap 31 is made to be in ON, automatic horizontal gauge tap 32 is made to be in the state of OFF, the spray valve 21 of cantilever 3 is operating as and opens, when making switch pump 30 be in ON and start to advance traveling, as shown in Figure 3, liquid is sowed from the multiple nozzles 33 be separately positioned on left cantilever 3a and central cantilever 3c and right cantilever 3b.
In the region of the so-called the edge of a field M close to ridge, when steering wheel 9 rotates more than set angle to carry out revolution action by operator, the cantilever 3(of revolution inner side is in the present embodiment for 3b) keep sowing posture while, the cantilever 3(3a in revolution outside) start to rise (between the first tow-away zone S1).When carrying out the revolution actions of roughly 90 degree, when steering wheel 9 is turned back to forward travel state by operator, driving vehicle 1 is at the cantilever 3(3a in revolution outside) under state for rising posture, with forward travel state to the direction running (the edge of a field travels interval S2) along ridge.And, when in the past carry out driving into sow region into the adjacent next one when, when steering wheel 9 rotates more than set angle to identical direction by driver again, the cantilever 3(3a outside the revolution risen) decline and become and sow posture (between the second tow-away zone S3).Further, driving vehicle 1 becomes the posture that forward direction travels, and sows region sow liquid while start to travel towards the next one.To travel via the edge of a field in the interval S2 process that S3 travels between the second tow-away zone at S1 between the first tow-away zone, even if make automatic horizontal gauge tap 32 be in OFF, also can carry out the cantilever 3(3b turning round inner side) automatic horizontal control.
In the present embodiment, be configured to, what cantilever 3 carried out is sowed and stops being undertaken by operator's manual operation spray valve 21, but also can adopt following structure: if identify revolution action, then automatically stop sowing of cantilever (3a) in revolution outside.
If control part 13 reads out the rotating operation information of more than the set angle of the steering wheel 9 when revolution starts, then make the cantilever 3(3a outside revolution) rise, and store the rotating operation information of this steering wheel 9, when reading out steering wheel 9 second time to more than the set angle of equidirectional rotating operation information, then start the cantilever 3(3a turning round outside) decline.Before obtaining the rotating operation information of this second time steering wheel 9, even if read out the operation information, the steering wheel rotation operation information below set angle that temporarily retreat in order to alignment bar etc., the cantilever 3(3a made outside revolution also can be maintained) posture that rises.
The judgement of revolution action both can according to the testing result of steering wheel operation detection sensor 41 of rotational angle detecting as mentioned above steering wheel 9, also can according to the testing result of running vehicle wheel rotation angle detecting sensor 42 of rotational angle detecting running vehicle wheel.
Make the cantilever 3(3a outside revolution for during revolution) rising rise to for which position, consider several method.First, can adopt from rising rise to the structure of setting-up time (such as 10 seconds), also can based on the testing result of cantilever angle of elevation detecting sensor (not shown), this cantilever angle of elevation detecting sensor detects until examine set angle it.
The automatic lifting of cantilever during above-mentioned revolution controls to be configured at automatic lifting gauge tap 31 as ON and switch pump 30 are also for carrying out control action during ON.
In addition, when turning round, under normal circumstances, operator is under the state making switch pump 30 be ON, cantilever 3(3a by by revolution outside) spray valve 21(21a) operation is to closed condition, travel interval S2 from S1 between the first tow-away zone via the edge of a field until S3, the cantilever 3(3b of revolution inner side between the second tow-away zone) and central cantilever 3c continue to sow liquid.Further, in the adjacent farmland of not sowing, when starting to sow, operator is by carrying out the cantilever 3(3a opening revolution outside) spray valve 21(21a) operation, thus again start to sow liquid from whole cantilever 3.
The feature of the liquid of present embodiment being sowed to the revolution action of vehicle is described.
Under normal circumstances, the revolution action of tractor or rice transplanter starts to terminate to revolution from revolution, continues rotation steering wheel 9 and once carries out the revolution of 180 degree.To this, there is larger difference in the following areas in the revolution action that vehicle sowed by the liquid of present embodiment, namely, rotate steering wheel 9 and start to turn round action, when between the first tow-away zone, S1 carries out the revolution of roughly 90 degree, for the time being steering wheel 9 is turned back to progressive position, after the edge of a field travels interval S2 traveling, if again rotate steering wheel 9 and turn round roughly 90 degree and via S3 between the second tow-away zone, then becoming towards the adjacent posture of not sowing region.Namely until carry out twice revolution action (operation) before returning turnback.
Namely, sow in vehicle at liquid, the cantilever 3 when sowing posture is longer than the width of driving vehicle 1 far away in left and right, the cantilever 3(3b of revolution inner side) enter the region of having sowed by means of only revolution, thus cause repeatedly on crops, sowing liquid.As in the present embodiment, travel interval S2 by arranging the edge of a field when turning round, thus as shown in Figure 6, the cantilever 3(3b of revolution inner side) do not repeat with the farmland of sowing, can sow.
In addition, even if under the state making automatic horizontal gauge tap 32 be OFF, can be also the occasion of ON at automatic lifting gauge tap 31, and liquid sow in when starting to turn round action, carry out the cantilever 3(3b turning round inner side) level control.
Fig. 9 is the figure that the state that level controls is described, illustrates that running vehicle wheel 4 abuts the concavo-convex of face, farmland G and driving vehicle body when tilting, cantilever 3 is maintained the state of flat-hand position or approximate horizontal posture.Under normal circumstances, to advance and the region of sowing liquid mostly is face, farmland is become smooth state by ploughing and weeding, if make the automatic horizontal of cantilever 3 control to be in ON, there is the situation causing following undesirable condition on the contrary, namely, because of rocking of cantilever 3 make to sow posture confusion reigned etc.
On the other hand, in the edge of a field M, concavo-convex more on the G of face, farmland, the left and right posture of driving vehicle 1 is easily chaotic.Especially, there is the situation of following undesirable condition of causing, namely, the cantilever 3(3b of revolution inner side) right ground level position, front end become too low because of vibration, abut with crops.In the present embodiment, when advancing and sow liquid, even if make the automatic horizontal of cantilever 3 control be in OFF, also can by turn round time carry out turn round inner side cantilever 3(3b) automatic horizontal control, prevent above-mentioned undesirable condition, sow smoothly and turn round.
Secondly, the condition that the automatic lifting of the cantilever 3 when limiting revolution controls below is illustrated.
The first, automatic lifting gauge tap 31 is the occasion of OFF state.Now, operator, when the edge of a field M turns round, operates cantilever actuating strut 26(26a when needing to make cantilever 3 increase) and make the cantilever 3(3a outside revolution) rise.
The second, in traveling, switch pump 30 is the occasion of OFF.This occasion, control part 13 is judged as not sowing liquid but simply travels, even if operator carries out revolution operation, the cantilever 3(3a in revolution outside) also do not rise.According to this structure, can prevent unexpected cantilever 3 to rise the undesirable condition caused.In addition, this occasion, detects with flow detection sensor 36 and does not have the situation of the flowing of the flow of liquid identical, even the structure of not carrying out elevating control is also passable.
3rd, if cantilever seat detecting sensor 14a detects the situation of cantilever 3 folding and unfolding on cantilever seat 14, then control part 13 is judged as the simple traveling of not sowing liquid, even if operator carries out revolution operation, and the cantilever 3(3a in revolution outside) also do not rise.
According to this structure, revolution during by moving in warehouse operation, other in the wall in the cantilever 3 that can prevent beyond thought rising from causing and warehouse or warehouse are placed thing and are collided and breakage etc.
In addition, in above-mentioned second occasion and the 3rd occasion, adopt automatic lifting gauge tap 31 be the structure that the state of ON does not also carry out elevating control, thus can prevent the cantilever 3 when have forgotten cut-out automatic lifting gauge tap 31 from unexpectedly carrying out lifting action.
4th, be ON, switch pump 30 at automatic lifting switch be also the occasion of ON, also can control as follows: if be detected as more than the setting speed of a motor vehicle by vehicle speed sensor 43 during revolution, then the cantilever 3(3a in restriction revolution outside) elevating control.When moving from whole farmland of having sowed to the farmland that other is not sowed, sometimes automatic lifting switch be ON and also make switch pump 30 be in ON state under, spray valve 21 cuts out and moves.Therefore, the occasion more than the setting speed of a motor vehicle, by being judged as not being the state of sowing and the elevating control limiting cantilever 3, thus can prevent the undesirable condition of cantilever 3 beyond thought rising when turning round.This occasion, also can adopt following structure: can carry out the occasion of the structure of conversion operations with traveling bar 44 pairs of operating speeds and travel speed, if traveling bar 44 is operated travel speed, then the automatic lifting of not carrying out cantilever 3 controls.
Secondly, the checking mode of cantilever 3 is described.
Automatic lifting when this checking mode is for confirming above-mentioned revolution controls, revolution time level controls the pattern that can work, it is characterized in that, under the state of not sowing liquid, carry out these control.The inspection switch 37 of operation board 11 is made to be in ON wanting checking mode.Further, if make automatic lifting gauge tap 31 be in ON and travel, under the state of not sowing liquid making switch pump 30 be in OFF, the past carries out driving into row revolution operation, then carry out above-mentioned automatic lifting and control and level control.
Thus, the confirming operation that automatic lifting controls and automatic horizontal controls when liquid also can turn round is not sowed.
