Secondly, with reference to Fig. 4 etc., automatic lifting control describes during for the turning in the rice transplanter of this form of implementation.

Usually, as shown in Figure 4, while make car body directly carry out the plantation of rice shoot.At this moment, utilize any line concentrator marker 18 of the left and right sides, on the ground in field, form datum line.In addition, in the example of Fig. 4, utilize the line concentrator marker 18R on car body right side to form datum line.The datum line of the line parallel of the rice shoot that forms whereby, and plant on the car body right side.

If car body arrives the end in field, then the operator turns car body, the travel direction conversion.When car body was turned, at first, the operator operated the plantation elevating lever, and plantation portion 3 is risen.When the operator detects when plantation portion 3 is risen automatic lifting control when control part begins to turn.

At first, control part automatically cuts off plantation clutch 50, interrupts the plantation of rice shoot.The position of in addition, plantation being interrupted is called " plantation interruption position ".In addition, control part utilizes the portion of reporting to begin to report action in the front and back that cut off plantation clutch 50.Specifically, utilize the portion of reporting to pipe intermittently and constantly and report sound.Whereby, can report automatic lifting control when turning towards periphery.But, reporting sound also can pipe continuously.

In addition, control part begins the instrumentation to the distance of going from plantation interruption position car body.In addition, the structure for being used to detect operating range will be described later.

Before and after the rising of plantation portion 3, control part makes concentrator marker supporting arm 9 upright, line concentrator marker 18 is in holds state.

Secondly, the operator operates steering wheel 7, makes car body turning (state of Fig. 5).As shown in Figure 5, will the distance of (turning starting position) be called " operating range before turning " to the position that begins to turn from the plantation interruption position." operating range before turning " can be obtained by " the just distance-negative distance of advancing of advancing ".Wherein, so-called " the just distance of advancing " refers to the distance that after the plantation of interrupting rice shoot, car body is advanced, and so-called " the negative distance of advancing " refers to the distance that after the plantation of interrupting rice shoot, car body is retreated.Like this, between after the plantation of seedling breaking seedling therefrom, turning, car body is retreated to the beginning car body.In addition, operating range also can become negative value (that is, also can beginning to turn being made by the plantation interruption position after car body retreats) before turning.

The rice transplanter 1 of this form of implementation, a certain amount of when above by operation at steering wheel 7, the side clutch 41 of turning medial is cut off.Whereby, because the trailing wheel 5 of turning medial becomes free state, so, can be along the car body of turning slidingly.

When car body carried out turning to a certain degree, the operator turned back to the neutral position with steering wheel 7.When steering wheel 7 was returned, the cut inboard side clutch 41 that circles round was connected once more.After the inboard side clutch 41 that circles round was connected, operator's operating grip was finely tuned the car body posture, returns the straight ahead state.As stated, the turning action of car body finishes (state of Fig. 6).

Control part descends plantation portion 3 before and after the end of turning.In addition, in the correct time for plantation portion 3 is descended, will be described later.

After making 3 declines of plantation portion, control part connects plantation clutch 50, begins plantation once more.

Below, for describing the correct time that connects plantation clutch 50.Control part is constituted as keeps watch on the distance (from the operating range of turning starting position) that car body goes after beginning to turn.When control part detect the plantation that reaches regulation from the operating range of turning starting position begin once more apart from the time, will plant clutch 50 and connect, begin plantation once more.

Beginning distance with reference to Fig. 7 once more for plantation below describes.It is the distance with " distance of turning ", " pawl offset distance ", " operating range before turning " addition that plantation begins distance once more.The distance of turning is rice transplanter 1 to be turned and car body goes during conversion direction distance, by the decisions such as turn performance of car body.The distance of turning is preestablished by control part.In addition, pawl offset distance is the offset distance that is used to adjust the position of connecting plantation clutch 50, and it is also by the decisions such as turn performance of car body.Pawl offset distance is preestablished by control part.

When control part detect from the operating range of turning starting position reach plantation begin once more apart from the time, make the plantation clutch 50 become connection status, begin the plantation of rice shoot once more.The position that begins to plant once more is called as " planting starting position once more " (with reference to Fig. 7).Through above control, can make the plantation interruption position of adjacent lines consistently begin plantation once more.When beginning to plant once more, control part stops the sound of reporting by the portion's of reporting generation.Like this, automatic lifting control finishes during turning.

In addition, in the front and back that begin once more of plantation, the control part concentrator marker supporting arm 9 that fell begins to utilize line concentrator marker 18 to form datum lines once more.At this moment, control part is automatically selected and turns to form the line concentrator marker (under the situation of Fig. 7, being the line concentrator marker 18L in left side) of line concentrator marker 18 opposition sides of datum line before, utilizes the line concentrator marker of this opposition side to form datum line.

The datum line that the operator utilizes line concentrator marker 18 to form during on one side with reference to the plantation before turning is Yi Bian go car body.Whereby, can plant rice shoot abreast with the rice shoot of the plantation before of turning.

Secondly, the feature structure for this form of implementation describes.

At first, in the control of automatic lifting when the turning of this form of implementation, control part is obtained the structure that the operating range of car body uses and is described.

In patent documentation 1, put down in writing the rotating speed of the drive shaft of rear wheel that detects turning medial and calculated the structure of the operating range of car body.But this structure must be useful on the sensor to each detection rotating speed of the power transmission shaft of left and right sides trailing wheel, so, exist the problem that cost increases.

About this point, the rice transplanter 1 of this form of implementation as noted earlier, be equipped with in gearbox body 11 and detect the turn-sensitive device 44 that plantation drives the rotating speed of power transmission shaft 52.The rotating speed of plantation driving power transmission shaft 52 and the operating range of car body are proportional.Therefore, in the rice transplanter 1 of this form of implementation, the mode that the rotating speed that drives power transmission shaft 52 with the plantation that detects according to turn-sensitive device 44 detects the operating range of car body constitutes.Under the situation of this structure, owing to can only drive on the power transmission shaft 52 turn-sensitive device 44 is set in plantation, so, compare with patent documentation 1, can reduce cost.

In addition, in the rice transplanter 1 of this form of implementation, turn-sensitive device 44 is arranged on the upstream side of plantation clutch 50.Thereby, can irrespectively utilize turn-sensitive device 44 to detect the rotating speed that plantation drives power transmission shafts 52 with cut-out, the connection of plantation clutch 50.

Secondly, the establishing method for the turning distance describes.That is,,, be necessary to set rightly in advance " distance of turning " in order to connect plantation clutch 50 in appropriate correct time as noted earlier.But the distance of turning is different because of the difference of the specification of the verticity of car body or car body.

Specifically, as described below.That is, for rice transplanter, sell line space (with the direction of the travel direction quadrature of car body on rice shoot interval each other) or the line number (number of planter units 20.Incidentally, as shown in Figure 2, the line number of the rice transplanter 1 of this form of implementation is 4) rice transplanter of different various specification.But if specifications such as line space or line number are different, then for car body is turned with conversion direction, needed distance (distance of turning) is also different.

Therefore, in the rice transplanter 1 of this form of implementation, can control part be set the line space of this rice transplanter 1 and the mode of line number constitutes when the initial setting.Control part calculates the turning distance corresponding to line space that sets and line number, stores.According to this structure, owing to can connect plantation clutch 50 with appropriate correct time corresponding to line space and line number, so, can it doesn't matter that ground will plant aligned position unites with line space or line number different.

Secondly, prevent that for being used to the control of aerial plantation from describing.That is, in the rice transplanter 1 of this form of implementation, the mode of the timing that plantation portion 3 descends is constituted with the speed change when turning beginning.As described below particularly.

In the rice transplanter 1 of this form of implementation, control part is kept watch on the travel speed of car body.In addition, the rice transplanter 1 of this form of implementation according to the rotary speed of the plantation driving power transmission shaft 52 that utilizes turn-sensitive device 44 to obtain, is obtained the travel speed of car body.Thereby, need not append the sensor that is used to detect travel speed.

In this form of implementation, control part begins the decline of plantation portion 3 more leaning on the position of the front of predetermined distance than planting once more the starting position.The position of the decline that begins plantation portion 3 is called " plantation decline starting position ".In addition, will be called as " the beginning offset distance descends " from plantation decline starting position to the distance of planting once more starting position (position that connects plantation clutch 50).

Control part is based on being about to the operation travel speed before of turning, setting the beginning offset distance that descends.More particularly, the operation travel speed before that is about to turn is fast more, then takes big decline to begin offset distance more.In other words, control part is fast more with travel speed, and the mode more early in correct time of the decline that begins plantation portion 3 is constituted.In view of the above, even under the fast situation of the travel speed of car body, the decline that also can prevent plantation portion 3 is out of turn and the situation of aerial plantation takes place.

In addition, if the beginning offset distance that descends is excessive, then under situation about having, can hit exactly in the process that car body is being turned, plantation portion 3 begins to descend.In this case, the worry that exist plantation portion 3 kiss the earths or ridge, sustains damage.Therefore, in the rice transplanter 1 of this form of implementation, make the beginning offset distance that descends be 1300mm to the maximum.Like this, because the upper limit through the beginning offset distance that set to descend, become too early the correct time that can prevent to begin the decline of plantation portion 3, so, can prevent the damage of plantation portion 3.

Secondly, the speed when plantation portion 3 is descended describes.

Under the situation of the upper-lower position of operator's manual operation plantation portion,, then exist and the inconsistent problem in target location if rising or falling speed is too fast.Therefore, the decrease speed of the plantation portion that utilizes the plantation elevating lever to obtain is set for carried out manually operated, speed slowly to a certain extent easily.But, when also consistent with it, then become the slack-off reason of decline meeting of the plantation portion that carries out through automatic control as if the decrease speed of the plantation portion that obtains through automatic lifting control.

Therefore, in the rice transplanter of this form of implementation, in manual operation and automatic lifting, make decrease speed different.The decrease speed of the plantation portion 3 that specifically, obtains with the automatic control through control part is set than the fast mode of decrease speed of the plantation portion 3 that obtains through manual operation.That is, under manually operated situation, through making it decline more lentamente, the upper-lower position with plantation portion 3 overlaps easily, when automatic lifting is controlled, accelerates decrease speed, and it is out of turn to prevent to descend.

Automatically terminating of automatic lifting control describes during secondly, for turning.

That is, automatic lifting control during above-mentioned turning is operating as prerequisite with in accordance with regulations turning pattern of car body (behind the last lift operations of plantation portion 3, turning after advancing, and the pattern of straight ahead once more).Thereby, exist under the operational circumstances that breaks away from this turning pattern, can not judge the problem in the correct time that begins once more to plant rightly.In addition, under situation such as disengaging field, the operator can break away from the operation of turning pattern wittingly sometimes.

Therefore, the rice transplanter 1 of this form of implementation constitutes in the following manner, that is, under the situation of the operation of the turning pattern that is broken away from regulation by the operator, automatic lifting control when turning through automatically removing prevents to violate operator's intention ground up-down plantation portion 3.

In this form of implementation; If enumerate the operation that breaks away from the turning pattern particularly, can enumerate out " normal anomaly of advancing ", " negative anomaly advances ", " backward going is unusual ", " it is unusual to turn ", " straight ahead from the turning process ", " the manual decline of plantation portion " etc.

" normal anomaly of advancing " refers to from the plantation interruption position and makes advance the continuously operation of (for example more than the 5mm) more than (straight ahead) stroke predetermined distance of car body.Under the situation of carrying out this operation, control part thinks that the operator does not make the meaning of car body turning, removes automatic lifting control when turning.

" negative anomaly advances " refers to and makes car body retreat the operation of (for example more than the 5mm) more than the predetermined distance continuously from the plantation interruption position.Under the situation of carrying out this operation, control part thinks that the operator does not make the meaning of car body turning, removes automatic lifting control when turning.

" backward going is unusual "; It is negative apart from from ∣ to refer to before turning just advance distance-advance of the absolute value ∣ of operating range) to become predetermined distance above (for example; More than the 5m) (that is, after interrupting plantation, surpassing the necessary operation of advancing or retreating).Under the situation of carrying out this operation, control part thinks that the operator does not make the meaning of car body turning, removes automatic lifting control when turning.

" it is unusual to turn " continues predetermined distance above (for example more than the 10m) though refer to the operation of turning, and turns and do not finish.Under the situation of carrying out this operation, be not intended to carry out u turn owing to can be judged as the operator, so control part is removed automatic lifting control when turning.

" from the straight ahead of turning midway " refers to making to turn and car body turned back to the operation of the state of straight ahead before finishing.Under the situation of having carried out this operation, owing to can be judged as the intention that the operator does not carry out u turn, so control part is removed automatic lifting control when turning.

So-called " the manual decline of plantation portion " refers to when turning in the automatic lifting control, and the operator operates the plantation elevating lever, so that plantation portion 3 is descended.Under the situation of having carried out this operation, because operator's intention is not through automatic lifting control but through manually making plantation portion 3 descend, so control part is removed automatic lifting control when turning.

As stated, break away from the operator under the situation of operation of turning pattern, think the intention of automatic lifting control when the operator does not continue to turn.Thereby in this case, automatic lifting control when turning through removing can prevent that the 3 violation operators' of plantation portion intention ground from being gone up and down.In addition, for example, even under the situation that automatic lifting is controlled when the intention that can violate the operator owing to maloperation begins to turn, under the situation that breaks away from the turning pattern, the releasing automatically of meeting quilt, so, can prevent dangerous play or plantation by mistake.

But, on the other hand, under the situation of disengaging turning pattern, if unconditionally remove automatic lifting control when turning, when then having inconvenience on the contrary.Thereby, even break away from the turning pattern, difference according to circumstances, it is more convenient under situation about having, not remove automatic lifting control meeting.

For example, after making the car body turning, before beginning plantation once more, under situation about having,, want to make car body temporarily to retreat in order to carry out the track correction.In this case, if remove automatic lifting control when turning, then can become the control of the intention of violating the operator on the contrary.

Therefore, the control part of this form of implementation constitutes in the following manner,, after the clutch when turning medial is connected, before plantation begins once more, makes under the situation of the operation that car body retreats automatic lifting control when not interrupting turning that is.Whereby, automatic lifting control car body is retreated to carry out the track correction in the time of can not interrupting turning.

In addition, if after the clutch of turning medial is connected, then exist the possibility that plantation portion 3 has descended.If under plantation portion 3 and ground state of contact, car body is retreated, the worry that then has plantation portion 3 and ridge collision to sustain damage.Therefore, control part constitutes in the following manner, that is, control part the clutch of turning medial by the situation of the operation that car body is retreated under, plantation portion 3 is risen.Whereby, can prevent the breakage of plantation portion 3.In addition, in this case, when car body advanced and arrive plantation decline starting position once again, control part carried out the automatic decline of plantation portion 3.

In addition, for example, when turning, in the automatic lifting control, under situation about having,, manually operate line concentrator marker 18 through operator's operation mark device operator.Under the situation of carrying out this operation, automatic lifting control is disengaged during as if turning, then can become the control of the intention of violating the operator on the contrary.

Therefore, control part constitutes in the following manner,, under the situation of having been operated the concentrator marker operator by the operator, only removes the automatic selection function of line concentrator marker that is, automatic lifting control when proceeding the turning of plantation portion 3.In this case, control part is controlled in the following manner, that is, utilize the line concentrator marker 18 by operator selected to form datum line on one side, plant on one side.Based on above structure, on one side the operator can utilize arbitrarily (left and right sides any one) line concentrator marker 18 to form datum lines, Yi Bian plant.And, owing to utilize the automatic selection of the line concentrator marker that control part carries out to be disengaged, therefore, can not form datum line by the undesirable line concentrator marker 18 of operator.

In addition, for example, in the turning of car body,, car body is temporarily stopped in order to continue seedling operation etc.In this case, the operator operates main shift lever " continuous seedling " position.

Like this, in the situation that car body is stopped for continuous seedling, be prerequisite to begin to plant operation once more afterwards.Thereby in the rice transplanter 1 of this form of implementation, control part constitutes in the following manner, that is, even the operation that car body is stopped, automatic lifting control is not removed yet during turning.Whereby, after continuous seedling finishes, through beginning going of car body once more, automatic lifting control in the time of can continuing to turn with keeping intact.

In addition, automatic lifting control becomes under the effective situation when turning, and as noted earlier, is rung by the sound of reporting that the portion of reporting produces.But, in that being stopped, car body continues in the operation of seedling, if reporting sound continues to ring, then exist very ear-piercing problem.Therefore, the control part of this form of implementation constitutes in the following manner, that is, when main shift lever is positioned at " continuous seedling " position, interrupt being reported by what the portion of reporting carried out.Whereby, can cosily continue the seedling operation.But, be not limited to stop fully reporting sound, also can control with the mode of the volume that reduces to report sound.

Then, the adjunctive program for rice shoot describes.

Carrying under the situation that the rice shoot on the rice transplanter is used up, having to replenish rice shoot.In this case, drive to the edge of ridge with making car body crosscut pillow, replenish the rice shoot that appends.At this moment, under situation about having, do not hope residual wheel vestige in the pillow ground.In this case, if, utilize buoyancy aid 16 ground gradings to eliminate the wheel vestige, then be very easily through plantation portion 3 is descended.

Therefore, the rice transplanter 1 of this form of implementation constitutes in the following manner,, can operate the plantation clutch operating lever through the operator that is, and the state that keeps reducing plantation portion 3 only cuts off plantation clutch 50 unchangeably.Whereby, owing to can and keep being gone contiguously in buoyancy aid 16 and ground under the state that interrupts plantation, so, can utilize this buoyancy aid 16 ground gradings, eliminate the wheel vestige.In addition, this operation can not become the condition subsequent of automatic lifting control when turning, so, automatic lifting control in the time of can proceeding to turn.

Specifically, when detecting under the state that plantation portion 3 has been lowered by, when cutting off the operation of plantation clutch 50 by the operator, control part transfers to " rice shoot supplement mode ".In addition, will transfer to " rice shoot supplement mode " state before and be called " normal mode ".In addition, control part will be planted clutch 50 cut positions as " plantation interruption position ", automatic lifting control when beginning to turn.

When cutting off plantation clutch 50 and transferring to the rice shoot supplement mode, the operator makes car body crosscut pillow ground straight ahead to the ridge edge in order to carry out replenishing of rice shoot.At this moment, as noted earlier, can utilize buoyancy aid 16 smooth pillow ground.Replenish if accomplish the rice shoot that carries out at the ridge edge, then the operator turns car body, returns to the plantation of rice shoot.Control part sustains damage in order to prevent plantation portion 3 and ground or ridge collision under the situation of the operation that car body turns is sent as an envoy in detection, and plantation portion 3 is risen.

And, when control part detects car body when driving to the position corresponding to the plantation interruption position, will plant clutch 50 and couple together, begin once more to plant.In addition, because this control is the control that is equal to after normal mode transfer kinking bundle, automatically being connected the control of planting clutch 50, so, omit detailed explanation.When beginning the plantation of rice shoot once more, control part returns to normal mode.

In addition; If during common turning when turning (under normal mode), in turning, not through plantation portion 3 is risen; But; Carrying out rice shoot when replenishing (rice shoot supplement mode), under situation about having, different operation when can be as required plantation portion 3 being gone up lift operations etc. with common turning.

As previously described, under normal mode, when detecting when carrying out the last lift operations of plantation portion 3 by the operator, automatic lifting control when beginning to turn, and, set the plantation interruption position.But, as noted earlier, owing to lift operations on the rice shoot supplement mode is carried out plantation portion as required, so when carrying out such operation, replacement plantation interruption position, can squint in the position that begins once more to plant at every turn.

Therefore; In the rice shoot supplement mode of the rice transplanter 1 of this form of implementation; Even that carries out plantation portion 3 manually goes up the trigger operation that lift operations etc. becomes the control of going up and down when beginning to turn, control part also can not change the plantation interruption position, automatic lifting control when proceeding to turn.Whereby, in the rice shoot supplement mode,,, can begin once more in appropriate position to plant so can not squint in the position that begins once more to plant because the trigger operation of the last lift operations through plantation portion 3 etc. does not change the plantation interruption position.

As top explanation, the rice transplanter 1 of this form of implementation has: car body 2; Plantation portion 3, said plantation portion 3 can oscilaltion; Plantation clutch 50, control is cut off, connected to the driving force that the said plantation of said plantation clutch 50 subtends portion 3 transmits; Control part, automatic lifting control when said control part is turned, automatic lifting control is used for planting in the car body turning time control production of hybrid seeds up-down and the plantation clutch 50 of portion 3 during said the turning; Engine 10, said engine 10 are drive sources of wheel and plantation portion 3.When turning in the automatic lifting control, control part automatically makes plantation portion 3 descend in turning or the correct time of the regulation after finishing of turning.In addition, after turn finishing, when car body arrives corresponding to the plantation of the plantation interruption position before the beginning of turning once more during the starting position, control part will plant clutch 50 and coupled together, and begin once more to plant.And this control part changes the timing that plantation portion 3 is descended based on the rotary speed that plantation drives power transmission shaft 52.

Like this, drive the rotary speed of power transmission shaft 52, the correct time that can plantation portion 3 descended according to the travel speed change of car body through judging plantation.And, for example of this form of implementation, when the car body travel speed is fast,, can prevent that before 3 declines of plantation portion finish, planting clutch 50 connects through shifting to an earlier date the correct time that plantation portion 3 will be descended.

Preferred implementing form of the present invention has been described above, and still, said structure can change by following mode.

Plantation portion 3 is revolving, and still, caterpillar rice transplanter also can be used structure of the present invention.

The operation that " operation that breaks away from the turning pattern of regulation " is not limited to enumerate in the literary composition.

The plantation elevating lever also can double as concentrator marker operator.

The power transmission shaft that utilizes turn-sensitive device 44 to detect revolution and rotary speed is not limited to plantation and drives power transmission shaft 52.For example, the 44a place, position that also can in Fig. 3, dot is provided with turn-sensitive device 44, utilizes this turn-sensitive device 44 to detect the revolution of Cardan shaft 39.

Become the operation of the trigger of automatic lifting control when turning, be not limited to the last lift operations of plantation portion.For example, also can consider with steering wheel 7 by more than the operating provision amount as trigger, the structure of automatic lifting control when beginning to turn.In addition, also can consider to make operation that car body retreats as trigger, the structure of automatic lifting control when beginning to turn.Like this, through according to various trigger operation, automatic lifting control when turning accordingly with various turning patterns.
