If car body arrives the end in field, then operator makes car body turn, and travel direction is changed. When making car body turn, first, operator operates plantation elevating lever, makes plantation portion 3 increase. When operator detect make plantation portion 3 increase time, when control portion starts to turn automatic lifting control.

First, control portion automatically shuts off plantation clutch 50, interrupts the plantation of rice shoot.It addition, Position plantation interrupted is referred to as " plantation interruption position ".It addition, control portion cut off plantation from Before and after clutch 50, notification unit is utilized to start to report action.Specifically, notification unit is utilized to break Continuous ground and the notification sound that pipes constantly.Whereby, can report to around and turn Time automatic lifting control.But, notification sound can also pipe continuously.

It addition, control portion starts the measurement to the distance that car body from plantation interruption position travels. It addition, for the structure for detecting operating range, will be described later.

Before and after the rising in plantation portion 3, control portion makes marker supporting arm 9 upright, makes line Marker 18 is in receiving state.

Secondly, operator operates steering wheel 7, makes car body turn (state of Fig. 5).Such as Fig. 5 Shown in, by the distance from plantation interruption position to the position (turning starting position) starting turning It is referred to as " operating range before turning "." operating range before turning " can be by " just distance-advance of advancing Negative distance " obtain.Wherein, what is called " just distance of advancing " refers to after interrupting the plantation of rice shoot Make the distance that car body advances, so-called " negative distance of advancing ", refer to interrupt rice shoot plantation it After make the distance that car body retreats.So, turn to beginning car body after the plantation of therefrom seedling breaking Seedling Between curved, it is possible to so that car body retreats.It addition, operating range can also become negative before turning Value (i.e., it is also possible to after being made car body retreat by plantation interruption position, starts to turn).

The rice transplanter 1 of this form of implementation, time more than steering wheel 7 is a certain amount of by operation, turns The side clutch 41 of inner side is cut off.Whereby, free shape is become due to the trailing wheel 5 of turning medial State, so, car body of can turning smoothly.

When car body carries out turning to a certain degree, steering wheel 7 is returned to neutral position by operator Put.When being returned by steering wheel 7, the cut-off side clutch 41 inside convolution is by again Connect.After side clutch 41 inside convolution is connected, operator operates handle, to car Body posture is finely adjusted, and returns straight ahead state.As it has been described above, the turning action knot of car body Bundle (state of Fig. 6).

Control portion, before and after turning terminates, makes plantation portion 3 decline.It addition, for making plantation portion 3 timings declined, will be described later.

After making plantation portion 3 decline, control portion connects plantation clutch 50, starts again at kind Plant.

Below, the timing for connection plantation clutch 50 illustrates.Control portion is configured to Monitor that car body starts the distance (operating range from turning starting position) travelled after turning. When control portion detects that the plantation that the operating range from turning starting position reaches to specify is opened again During beginning distance, plantation clutch 50 is connected, starts again at plantation.

Referring to Fig. 7, distance is started again at for plantation to illustrate.Plantation start again at away from From be " turning distance ", " pawl position offset distance ", " operating range before Zhuan Waning " are added away from From.Turning distance is to make rice transplanter 1 turn and car body travels during conversion direction distance, by car The turn performances of body etc. determine.Turning distance is preset by the portion of control.It addition, pawl position is inclined Moving distance is the offset distance for adjusting the position connecting plantation clutch 50, and it is also by car body Turn performance etc. determine.Pawl position offset distance is preset by the portion of control.

When control portion detects that the operating range from turning starting position reaches plantation and starts again at During distance, make plantation clutch 50 become connection status, start again at the plantation of rice shoot.Again The position starting plantation is referred to as " plantation starts again at position " (with reference to Fig. 7).By above control System, can make the plantation interruption position of adjacent lines consistently start again at plantation.When again opening When beginning to plant, control portion stops the notification sound produced by notification unit.So, automatically rise during turning Fall control terminates.

It addition, before and after plantation starts again at, fell marker supporting arm 9 in control portion, then The secondary line marker 18 that starts with forms datum line.At this moment, control portion automatically selects and turns Line marker (the feelings at Fig. 7 of line marker 18 opposition side of datum line are formed before curved Under condition, for the line marker 18L in left side), utilize the line marker of this opposition side to form base Directrix.

Operator is while with reference to the base utilizing line marker 18 to be formed during plantation before turning Directrix, makes car body travel.Whereby, can plant abreast with the rice shoot of plantation before turning Plant rice shoot.

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

In controlling firstly, for the automatic lifting when the turning of this form of implementation, control portion obtains The structure of the operating range of car body illustrates.

In patent documentation 1, describe the rotating speed of the drive shaft of rear wheel of detection turning medial and count Calculate the structure of the operating range of car body.But, after this structure is it is necessary to have be used for left and right The sensor of each detection rotating speed of the power transmission shaft of wheel, so, there is asking of cost increase Topic.

About this point, the rice transplanter 1 of this form of implementation, as previously described, at gearbox body The turn-sensitive device 44 that detection plantation drives the rotating speed of power transmission shaft 52 it is equipped with in 11.Plantation drives The rotating speed of power transmission shaft 52 is proportional to the operating range of car body.Therefore, inserting in this form of implementation In seedling machine 1, the rotating speed of power transmission shaft 52 is driven with the plantation detected according to turn-sensitive device 44 The mode of the operating range of detection car body is constituted.In the case of that construction, due to can only Drive in plantation and on power transmission shaft 52, a turn-sensitive device 44 is set, so, with patent documentation 1 Compare, cost can be reduced.

It addition, in the rice transplanter 1 of this form of implementation, turn-sensitive device 44 be arranged on plantation from The upstream side of clutch 50.Thus, it is possible to plantation clutch 50 cut-out, connect independently Turn-sensitive device 44 detection plantation is utilized to drive the rotating speed of power transmission shaft 52.

Secondly, the establishing method for turning distance illustrates.I.e., as previously described, for Connect plantation clutch 50 in appropriate timing, it is necessary to set the most rightly " turn away from From ".But, turning distance is different because of the verticity of car body or the difference of the specification of car body.

Specifically, as described below.That is, for rice transplanter, sell line space (with car The rice shoot on direction that the travel direction of body is orthogonal interval each other) or line number (planter units 20 Number.Incidentally, as in figure 2 it is shown, the line number of the rice transplanter 1 of this form of implementation is 4) The rice transplanter of different various specifications.But, if line space or line number equal-specification are different, Then in order to make car body turn with conversion direction, required distance (turning distance) is also different.

Therefore, in the rice transplanter 1 of this form of implementation, with can be to control when initial setting The mode of line space and line number that portion sets this rice transplanter 1 is constituted.Control portion calculate corresponding to Set line space and the turning distance of line number, store.According to this structure, due to Plantation clutch 50 can be connected with the appropriate timing corresponding to line space and line number, so, Can different from line space or line number it doesn't matter that plantation aligned position is united by ground.

Secondly, for for preventing the control planted in the air from illustrating.That is, in this enforcement shape In the rice transplanter 1 of formula, to make plantation portion 3 just decline according to the speed change turned when starting Time mode constitute.The most as described below.

In the rice transplanter 1 of this form of implementation, control portion monitors the travel speed of car body.It addition, The rice transplanter 1 of this form of implementation, drives transmission according to the plantation utilizing turn-sensitive device 44 to obtain The rotary speed of axle 52, obtains the travel speed of car body.It is therefore not required to add for detecting The sensor of travel speed.

In this form of implementation, control portion is starting again at position more by predetermined distance than plantation The position of front, starts the decline in the portion of planting 3.The position starting the decline in the portion of planting 3 is claimed For " plantation declines starting position ".Again open it addition, starting position will be declined from plantation to plantation The distance of beginning position (connecting the position of plantation clutch 50) is referred to as " declining and starting offset distance From ".

Control portion, according to the travel speed that will carry out before cornering operation, sets and declines beginning partially Move distance.More specifically, the travel speed before will carrying out cornering operation is the fastest, then get over Big decline is taked to start offset distance.In other words, control portion is the fastest with travel speed, then More make to start the timing of the decline in the portion of planting 3 mode earlier to constitute.Accordingly, even if at car body Travel speed fast in the case of, it is also possible to the decline preventing plantation portion 3 is out of turn and occurs The situation of aerial plantation.

If it addition, it is excessive to decline beginning offset distance, the most in other instances, can at car body just Hitting exactly in the process carrying out turning, plantation portion 3 begins to decline.In this case, also exist The worry that plantation portion 3 contacts ground or ridge, sustains damage.Therefore, in this form of implementation In rice transplanter 1, make decline start offset distance and be 1300mm to the maximum.So, owing to passing through Set and decline the upper limit starting offset distance, be possible to prevent to start the timing of the decline in the portion of planting 3 Become too early, so, it is possible to prevent the damage in plantation portion 3.

Secondly, for making speed when plantation portion 3 declines illustrate.

In the case of the upper-lower position in operator's manual operation plantation portion, if rising or falling speed is too fast, Then there is the problem inconsistent with target location.Therefore, plantation elevating lever will be utilized to obtain The decrease speed in plantation portion is set to that be easily operated manually, the most slowly Speed.But, if controlled the decrease speed phase the most therewith in the plantation portion obtained by automatic lifting Time consistent, then become by automatically controlling the reason that the decline in the plantation portion carried out can be slack-off.

Therefore, in the rice transplanter of this form of implementation, in manual operation and automatic lifting, make Decrease speed is different.Specifically, with by the plantation portion 3 automatically controlling acquisition in control portion The decrease speed mode faster than the decrease speed in the plantation portion 3 being manually operated acquisition carry out Set.I.e., in the case of manual operation, relatively slowly it is allowed to decline by ratio, easily will The upper-lower position in plantation portion 3 overlaps, and when automatic lifting controls, accelerates decrease speed, permissible Prevent from declining out of turn.

Secondly, time for turning, automatic lifting control automatically terminates and illustrates.

That is, during above-mentioned turning, automatic lifting controls, with car body by the cornering mode (plantation of regulation After the lifting operations in portion 3, turn after advancing, and the pattern of straight ahead again) grasped As premise.Accordingly, there are under carrying out the operational circumstances departing from this cornering mode, can not The problem judging rightly to start again at the timing of plantation.It addition, when disengaging field, Sometimes operator can carry out departing from the operation of cornering mode wittingly.

Therefore, the rice transplanter 1 of this form of implementation is constituted in the following manner, i.e. by operator In the case of carrying out departing from the operation of the cornering mode of regulation, during by automatically releasing turning from Dynamic elevating control, lifts plantation portion 3 with preventing from violating the intention of operator.

In this form of implementation, if specifically enumerating the operation departing from cornering mode, can enumerate Go out " advance normal anomaly ", " advance negative anomaly ", " backward going abnormal ", " turning abnormal ", " from Straight ahead during turning ", " Manual descending in plantation portion " etc..

" advance normal anomaly " refers to make car body advance continuously (straight line from plantation interruption position Advance) operation of more than stroke predetermined distance (such as more than 5mm).Carrying out this behaviour In the case of work, control portion thinks that operator does not make the meaning that car body is turned, when releasing turning Automatic lifting controls.

" advance negative anomaly " refers to make car body retreat predetermined distance continuously from plantation interruption position The operation of (such as more than 5mm) above.In the case of carrying out this operation, control portion Think that operator does not make the meaning that car body is turned, release automatic lifting when turning and control.

" backward going abnormal ", the absolute value of the front operating range that refers to turn (advance just away from From-negative distance of advancing) become more than predetermined distance (such as, more than 5m) (that is, in After sterilization is planted, it is performed for more than the operation advanced or retreat of necessity).Carrying out this operation In the case of, control portion thinks that operator does not make the meaning that car body is turned, when releasing is turned certainly Dynamic elevating control.

" turn abnormal " although refer to cornering operation continue more than predetermined distance (such as 10m with On), but turn and be not over.In the case of carrying out this operation, due to may determine that for Operator is not intended to carry out u turn, so, control portion releases automatic lifting when turning Control.

" straight ahead from midway of turning ", refers to be returned by car body before making turning terminate Return to the operation of the state of straight ahead.In the case of having carried out this operation, due to permissible It is judged as that operator does not carry out the intention of u turn, so, when the releasing of control portion is turned certainly Dynamic elevating control.

So-called " Manual descending in plantation portion ", refers to when turning in automatic lifting control, behaviour Vertical person operates plantation elevating lever, in order to manually make plantation portion 3 decline.Carrying out this operation In the case of, owing to operator is intended to not controlled by automatic lifting but manually make kind Plant portion 3 to decline, so, control portion releases automatic lifting when turning and controls.

As it has been described above, in the case of operator carries out the operation of disengaging cornering mode, it is believed that behaviour The intention that when vertical person does not continue to turn, automatic lifting controls.Thus, in this case, logical Cross automatic lifting when releasing is turned to control, be possible to prevent plantation portion 3 to violate the intention ground of operator Lifted.It addition, such as, even if starting in the intention that can violate operator due to maloperation In the case of during turning, automatic lifting controls, in the case of departing from cornering mode, can be by automatically Ground releases, so, it is possible to prevent dangerous play or plantation by mistake.

But, on the other hand, in the case of departing from cornering mode, turn if unconditionally releasing Time curved, automatic lifting controls, the when of having inconvenience the most on the contrary.Thus, turn even if departing from Pattern, difference according to circumstances, the most not releasing automatic lifting control can be more convenient.

Such as, after making car body turn, before starting again at plantation, in other instances, In order to carry out orbital exponent, it is desirable to make car body temporarily retreat.In this case, if releasing and turning Time curved, automatic lifting controls, and can become the control of the intention violating operator the most on the contrary.

Therefore, the control portion of this form of implementation is constituted in the following manner, i.e. working as turning medial Clutch connected after, before plantation starts again at, the operation carrying out making car body retreat In the case of, when not interrupting turning, automatic lifting controls.Whereby, can not interrupt during turning automatic Make car body retreat to carry out orbital exponent elevating control.

It addition, if in the clutch of turning medial connected after if, then there is kind Plant portion 3 in the probability declined.If making when plantation portion 3 contacts with ground Car body retreats, then have plantation portion 3 to collide, with ridge, the worry sustained damage.Therefore, control portion Constitute in the following manner, i.e. control portion makes afterwards the clutch of turning medial is connected In the case of the operation that car body retreats, plantation portion 3 is automatically made to increase.Whereby, it is possible to prevent The breakage in plantation portion 3.It addition, in this case, advance at car body and arrive plantation once again When declining starting position, control portion carries out the automatic decline in plantation portion 3.

It addition, such as, during when turning, automatic lifting controls, in other instances, by behaviour Vertical person's operation mark device operator, manually operation line marker 18.Carrying out this operation In the case of, if automatic lifting controls to be released from when turning, violation operator can be become the most on the contrary The control of intention.

Therefore, control portion is constituted in the following manner, i.e. operated marker behaviour by operator In the case of making device, only release the automatic function selecting of line marker, proceed plantation portion 3 turning time automatic lifting control.In this case, control portion is controlled in the following manner System, i.e. utilize the line marker 18 selected by operator to form datum line, while entering Row plantation.According to above structure, operator can utilize arbitrarily (left and right any one) Line marker 18 forms datum line, plants.It is additionally, since and utilizes control portion to enter The automatically selecting of marker of line of row is released from, therefore, and will not be by undesirable stroke of operator Line marker 18 forms datum line.

It addition, such as, in the turning of car body, in order to carry out continuous Seedling operation etc., sometimes make car Body temporarily ceases.In this case, main shift lever is operated " continuous Seedling " position by operator.

So, in the situation temporarily making car body stop to continue Seedling, to start again at kind afterwards Premised on planting operation.Thus, in the rice transplanter 1 of this form of implementation, control portion is with following side Formula is constituted, i.e. even if carrying out the operation making car body stop, automatic lifting during turning in turning Control not release.Whereby, after continuous Seedling terminates, by keeping intact start again at car The traveling of body, when can continue to turn, automatic lifting controls.

It addition, in the case of when turning, automatic lifting controls to become effectively, as previously described, The notification sound ring produced by notification unit.But, carry out in the operation of continuous Seedling making car body stop, If notification sound continues ring, then there is the most ear-piercing problem.Therefore, this form of implementation Control portion is constituted in the following manner, i.e. when main shift lever is positioned at " continuous Seedling " position, interrupt by The notification that notification unit is carried out.Whereby, continuous Seedling operation can cosily be carried out.But, not office It is limited to stop reporting sound completely, it is also possible to be controlled in the way of reducing the volume of notification sound.

Then, the adjunctive program for rice shoot illustrates.

In the case of the rice shoot being mounted on rice transplanter is used up, it has to supplement rice shoot.At this In the case of Zhong, drive to the edge of ridge with making the crosscutting pillow of car body, supplement the rice shoot added.This Time, in other instances, it is undesirable at pillow residual wheel vestige on the ground.In this case, If by making plantation portion 3 decline, utilize buoyancy aid 16 ground grading to eliminate wheel vestige, then It is the most easily.

Therefore, the rice transplanter 1 of this form of implementation is constituted in the following manner, i.e. can be by behaviour Vertical person operates plantation clutch operating lever, keeps the state reducing plantation portion 3 the most only to cut off Plantation clutch 50.Whereby, due to can when interrupt plantation and keep make to float Body 16 travels contiguously with ground, so, it is possible to use this buoyancy aid 16 ground grading, eliminate Wheel vestige.It addition, the condition subsequent that when this operation will not become turning, automatic lifting controls, So, when can proceed to turn, automatic lifting controls.

Specifically, when detect be lowered by plantation portion 3, operator enter When row cuts off the operation of plantation clutch 50, control portion transfers to " rice shoot supplement mode ".It addition, The state before " rice shoot supplement mode " that transfers to is referred to as " normal mode ".It addition, control portion Using the cut-off position of plantation clutch 50 as " plantation interruption position ", automatic when starting to turn Elevating control.

When cutting off plantation clutch 50 and transferring to rice shoot supplement mode, operator is in order to carry out Supplementing of rice shoot, makes car body crosscutting pillow ground straight ahead to ridge edge.At this moment, such as above institute State, it is possible to use buoyancy aid 16 smooth pillow ground.If the rice shoot completing to carry out at ridge edge supplements, Then operator makes car body turn, and returns to the plantation of rice shoot.Control portion turns at detection car body of sening as an envoy to In the case of curved operation, sustain damage to prevent plantation portion 3 from colliding with ground or ridge, Plantation portion 3 is automatically made to increase.

Further, when control portion detects that car body drives to the position corresponding to plantation interruption position, Plantation clutch 50 is coupled together, starts again at plantation.Further, since this control with logical The control automatically connecting plantation clutch 50 after norm formula transfer kinking bundle is the control of equivalent System, so, omit detailed description.When starting again at the plantation of rice shoot, control portion recovers To normal mode.

It addition, if common when turning when turning () under normal mode, in turning, Plantation portion 3 is the most manually made to increase, but, when carrying out rice shoot and supplementing, (rice shoot supplements mould Formula), in other instances, as required plantation portion 3 can be carried out lifting operations etc. with common Operations different during turning.

As previously described, under normal mode, carried out plantation portion 3 when detecting by operator During lifting operations, when starting to turn, automatic lifting controls, and, set plantation interruption position. But, as previously described, owing to as required plantation portion being risen in rice shoot supplement mode Operation, so, when carrying out such operation, resetting plantation interruption position every time, again open The position beginning to plant can offset.

Therefore, in the rice shoot supplement mode of the rice transplanter 1 of this form of implementation, even if planting The manual lifting operations etc. planting portion 3 becomes the trigger operation of elevating control when starting to turn, control Portion processed also is able to not change plantation interruption position, and when proceeding to turn, automatic lifting controls.Borrow This, in rice shoot supplement mode, due to by the trigger of the lifting operations etc. in plantation portion 3 Plantation interruption position is changed in operation, so, the position starting again at plantation will not offset, energy Enough start again at plantation in appropriate position.

As explained above, the rice transplanter 1 of this form of implementation has: car body 2;Plantation Portion 3, described plantation portion 3 can oscilaltion;Plantation clutch 50, described plantation clutch 50 pairs of driving forces to the transmission of described plantation portion 3 cut off, connect control;Control portion, institute Stating automatic lifting when control portion turns to control, during described turning, automatic lifting controls to be used for Lifting and the plantation clutch 50 in portion 3 is planted in the car body turning time control production of hybrid seeds;Electromotor 10, described Motivation 10 is the driving source in wheel and plantation portion 3.During when turning, automatic lifting controls, control Portion in turning or the timing of regulation after terminating of turning, automatically makes plantation portion 3 decline.Separately Outward, after turning terminates, when car body arrives corresponding to the plantation interruption position before starting of turning When plantation starts again at position, plantation clutch 50 is coupled together, starts again at kind by control portion Plant.Further, this control portion drives the rotary speed change of power transmission shaft 52 to make plantation portion according to plantation 3 timings declined.

So, by judging that plantation drives the rotary speed of power transmission shaft 52, can be according to car body Travel speed change makes the timing that plantation portion 3 declines.Further, such as, such as this form of implementation institute State, when car body travel speed is fast, shifted to an earlier date by the timing that plantation portion 3 will be made to decline, permissible Prevent plantation portion 3 decline complete before plant clutch 50 connect.

It is described above the preferred embodiment of the present invention, but, said structure can be by following Mode changes.

Plantation portion 3 is revolving, but, caterpillar rice transplanter can also apply the present invention Structure.

" operation of the cornering mode of disengaging regulation " is not limited to the operation enumerated in literary composition.

Plantation elevating lever can also double as marker operator.

The power transmission shaft utilizing turn-sensitive device 44 to detect revolution and rotary speed is not limited to plant Plant driving power transmission shaft 52.For example, it is also possible to set at the position 44a being represented by dashed line in figure 3 Put turn-sensitive device 44, utilize this turn-sensitive device 44 to detect the revolution of Cardan shaft 39.

The operation of the trigger that automatic lifting controls when becoming turning, it is not limited to plantation portion Lifting operations.For example, it is also possible to consider using steering wheel 7 by more than operating provision amount as triggering Device, the structure that when starting to turn, automatic lifting controls.Alternatively, it is also possible to after considering to make car body The operation moved back is as trigger, the structure that when starting to turn, automatic lifting controls.So, pass through According to various trigger operation, automatic lifting when turning accordingly with various cornering mode Control.
