In the first motion arm 80a of Fig. 6, the position of the second motion arm 80b; First, second first seedling plantation cable wire 72a and the 3rd, the 4th second seedling plantation cable wire 72b are under the state that is pulled, and the plantation of each bar is connected with part clutch 51 and seedling cultivation device 13 is moved.In addition; At this moment first, second first send seedling cable wire 73a outer cable wire 73A and the 3rd, the 4th second send the outer cable wire 73B of seedling cable wire 73b the position; As interior cable wire first, second first send seedling cable wire 73a and the 3rd, the 4th second send seedling cable wire 73b to be in lax state and first, second and the 3rd, the 4th 's the seedling that send is connected with part clutch 53, what drive first, second and the 3rd, the 4th send seedling band 6c.At this moment the first motion arm 80a, the position of the second motion arm 80b are called X1, X2 position respectively.In addition, first, second first send seedling cable wire 73a and the 3rd, the 4th second send seedling cable wire 73b and the outer cable wire that moves (outer cable wire 73A and outer cable wire 73B) relative motion.

And; As stated; When the plantation of each bar is connected with part clutch 51; Exactly as first seedling of interior cable wire plantation cable wire 72a, when second seedling plantation cable wire 72b is pulled, each bar send seedling with 53 connections of part clutch the time, send seedling cable wire 73a, second to send seedling cable wire 73b to be in the relaxed state as first of interior cable wire exactly.And; The outer cable wire 73A, second that the outer cable wire 72A of these first seedling plantation cable wires 72a, second seedling plantation cable wire 72b, first seedling plantation cable wire 72a, the outer cable wire 72B and first of second seedling plantation cable wire 72b send seedling cable wire 73a, second to send seedling cable wire 73b, first to send seedling cable wire 73a send the outer cable wire 73B of seedling cable wire 73b etc., near the first motion arm 80a, the second motion arm 80b, is configured to length direction and all aligns at equidirectional.And as shown in Figure 6, two cable wires 72,73 are configured to almost parallel and move (for example, in Fig. 6, being roughly straight line at above-below direction) along the vertical direction at each bar.

If cam 75 since the rotation of motor 70 and revolve along the arrow B direction from the position of Fig. 6 turn 90 degrees; Then just contact from contacting to become with the periphery of minor diameter with the periphery of the large-diameter portion of cam 75 with the roller 81 of the first motion arm 80a of cam 75 butts; Therefore; Roller 81 to arrow C a direction move and be connected with first, second first seedling plantation cable wire 72a and first, second first to send the first motion arm 80a of seedling cable wire 73a be that rotate at the center with the fulcrum 82a that is supported on the gripper shoe 65; The leading section of the first motion arm 80a moves to arrow Da direction, moves to the position shown in Fig. 7 (a).At this moment the position of the first motion arm 80a is called the Y1 position.

Through the first motion arm 80a is moved to arrow Da direction; Thereby first of first, second that connects with the leading section of the first motion arm 80a send the outer cable wire 73A of seedling cable wire 73a and the first motion arm 80a to move; When first, second first sent seedling cable wire 73a to be pulled, first, second first seedling plantation cable wire 72a was to arrow Da direction action and lax and make clutch separately be in non-drive state.That is, first seedling plantation cable wire 72a through making first, second is to the action of arrow Da direction, and seedling cultivation device 13 is failure to actuate with 51 disconnections of part clutch thereby make first, second plantation.In addition; Through making first, second first send the outer cable wire 73A of seedling cable wire 73a to move to arrow Da direction with the first motion arm 80a; Thereby make first, second first send seedling cable wire 73a to be pulled and first, second the seedling that send is broken off with part clutch 53, what do not drive first, second send seedling band 6c.

On the other hand; Even revolving along the arrow B direction from the position of Fig. 6, cam 75 turn 90 degrees; Owing to still be in the periphery state of contact with the large-diameter portion of cam 75 with the roller 81 of the second motion arm 80b of cam 75 butts; Thereby be connected with the 3rd, the 4th second seedling plantation cable wire 72b and the 3rd, the 4th second send the second motion arm 80b of seedling cable wire 73b not change the position (X2 position) that is in Fig. 6 state, therefore, under the state that second seedling plantation cable wire 72b does not move; Three, the 4th plantation is in the state of connection with part clutch 51,13 actions of seedling cultivation device.In addition, the 3rd, the 4th second send seedling cable wire 73b also to be in not action state, the 3rd, the 4th the seedling that send is in the state of connection with part clutch 53, drive the 3rd, the 4th send seedling band 6c.

Then, if cam 75 revolves and turn 90 degrees (from the position of Fig. 6 along arrow B direction Rotate 180 degree) again along the arrow B direction, then the first motion arm 80a, the second motion arm 80b become the state shown in Fig. 7 (b).

At this moment; Owing to be in the periphery state of contact with the minor diameter of cam 75 with the roller 81 of the first motion arm 80a of cam 75 butts; Thereby be connected with first, second first seedling plantation cable wire 72a and first, second first send the first motion arm 80a of seedling cable wire 73a not change the state (Y1 position) that is in Fig. 7 (a); Therefore, first, second plantation is in the state of disconnection with part clutch 51 and seedling cultivation device 13 does not move.In addition, first, second sending seedling to be in the state of disconnection with part clutch 53 and do not drive first, second send seedling band 6c.

On the other hand, the roller 81 of the second motion arm 80b is in from contacting the periphery state of contact that is converted to minor diameter with the periphery of the large-diameter portion of cam 75.Therefore roller 81 moves to arrow C b direction (Fig. 6); And be connected with the 3rd, the 4th second seedling plantation cable wire 72b and the 3rd, the 4th second to send the second motion arm 80b of seedling cable wire 73b be that rotate at the center with the fulcrum 82b that is supported on the gripper shoe 65; The leading section of the second motion arm 80b moves to arrow Db direction, moves to the position shown in Fig. 7 (b).At this moment the position of the second motion arm 80b is called the Y2 position.

Through the second motion arm 80b is moved to arrow Db direction; Thereby the 3rd, the 4th 's of connecting with the leading section of the second motion arm 80b second send the outer cable wire 73B of seedling cable wire 73b and the second motion arm 80b to move; Three, the 4th second when sending seedling cable wire 73b to be pulled, and the 3rd, the 4th second seedling plantation cable wire 72b is to the action of arrow Db direction and make clutch separately be in non-drive state.That is, through making the 3rd, the 4th second seedling plantation cable wire 72b to the action of arrow Db direction, seedling cultivation device 13 does not move with 51 disconnections of part clutch thereby make the 3rd, the 4th plantation.In addition; Through make the 3rd, the 4th second send the outer cable wire 73B of seedling cable wire 73b to move to arrow Db direction with the second motion arm 80b; Thereby make the 3rd, the 4th second send seedling cable wire 73b to be pulled and the 3rd, the 4th the seedling that send is broken off with part clutch 53, do not drive the 3rd, the 4th send seedling band 6c.

Then, turn 90 degrees (spending along arrow B direction rotation 270 from the position of Fig. 6) if cam 75 revolves along the arrow B direction again, then the first motion arm 80a, the second motion arm 80b become the state shown in Fig. 7 (c).

At this moment, owing to be in from contacting the periphery state of contact that is converted to large-diameter portion with the periphery of the minor diameter of cam 75 with the roller 81 of the first motion arm 80a of cam 75 butts.Therefore; Roller 81 is to moving with arrow C a direction in the opposite direction; And be connected with first, second first seedling plantation cable wire 72a and first, second first to send the first motion arm 80a of seedling cable wire 73a be that rotate at the center with the fulcrum 82a that is supported on the gripper shoe 65; The leading section of the first motion arm 80a arrives the position shown in Fig. 7 (c) to moving with arrow Da direction in the opposite direction, and the position of the first motion arm 80a turns back to the X1 position.

When the first motion arm 80a was positioned at the X1 position, as stated, first, second first seedling plantation cable wire 72a was pulled, i.e. the plantation of each bar is in on-state with part clutch 51 and makes 13 actions of seedling cultivation device.In addition, first send seedling cable wire 73a lax and make first, second send seedling with 53 connections of part clutch and drive first, second send seedling band 6c.

On the other hand; Owing to be in the periphery state of contact with the minor diameter of cam 75 with the roller 81 of the second motion arm 80b of cam 75 butts; Thereby be connected with the 3rd, the 4th second seedling plantation cable wire 72b and the 3rd, the 4th second send the second motion arm 80b of seedling cable wire 73b not change the state of the state (Y2 position) that is in Fig. 7 (b); Therefore, the 3rd, the 4th plantation also is in the state of disconnection with part clutch 51, and seedling cultivation device 13 does not move.In addition, the 3rd, the 4th the seedling that send is in the state of disconnection with part clutch 53, do not drive the 3rd, the 4th send seedling band 6c.

Then; If cam 75 revolves along the arrow B direction and turn 90 degrees (revolving three-sixth turn along the arrow B direction from the position of Fig. 6); Then the first motion arm 80a, the second motion arm 80b return the state of Fig. 6; Promptly be in the X1 position, and first, second first seedling plantation cable wire 72a and the 3rd, the 4th second seedling plantation cable wire 72b are pulled and make the plantation of each bar to connect with part clutch 51, seedling cultivation device 13 moves.In addition; First, second first send seedling cable wire 73a and the 3rd, the 4th second send seedling cable wire 73b also lax; Make first, second and the 3rd, the 4th 's the seedling that send be in on-state with part clutch 53, what drive first, second and the 3rd, the 4th send seedling band 6c.

Like this; Two arm 80a, 80b are in the position of X1, X2; First, second and the 3rd, the 4th 's the seedling that send all is in on-state with part clutch 53; What drive first, second and the 3rd, the 4th send seedling band 6c, and first, second and the 3rd, the 4th 's plantation also is in on-state with part clutch 51, and seedling cultivation device 13 also moves (state of Fig. 6).

Then; The first motion arm 80a is in the Y1 position and the second motion arm 80b during in the X2 position, and first, second the seedling that send breaks off with part clutch 53, does not drive first, second and send seedling band 6c; First, second plantation also is in off-state with part clutch 51; Seedling cultivation device 13 also is failure to actuate, but because the 3rd, the 4th the seedling that send is in on-state with part clutch 53, thus drive the 3rd, the 4th send seedling band 6c; Three, the 4th plantation also is in on-state with part clutch 51, and seedling cultivation device 13 also moves (state of Fig. 7 (a)).

Then; Two arm 80a, 80b are in the position of Y1, Y2; First, second and the 3rd, the 4th 's the seedling that send all is in off-state with part clutch 53; What do not drive first, second and the 3rd, the 4th send seedling band 6c, and first, second and the 3rd, the 4th 's plantation also is in off-state with part clutch 51, seedling cultivation device 13 also be failure to actuate (state of Fig. 7 (b)).

Then; The first motion arm 80a is in the X1 position and the second motion arm 80b during in the Y2 position; Three, the 4th the seedling that send breaks off with part clutch 53, does not drive the 3rd, the 4th and send seedling band 6c, and the 3rd, the 4th plantation also is in off-state with part clutch 51; Seedling cultivation device 13 also is failure to actuate; But first, second sending seedling to be in on-state with part clutch 53 and drive first, second send seedling band 6c, first, second plantation also is in on-state with part clutch 51,13 actions (state of Fig. 7 (c)) of seedling cultivation device.

Like above explanation, utilize ridge culture shown in Figure 6 already to use clutch unit 62, each cable wire 72,73 has obtained such four kinds of action forms.

And; Through adopting this structure; Because in clutch unit 62 is already used in ridge culture; First of the action usefulness of sending seedling band 6c is sent first seedling plantation cable wire 72a, second seedling plantation cable wire 72b etc. of the action usefulness that seedling cable wire 73a, second send seedling cable wire 73b and seedling cultivation device 13 are configured to its length direction, and be configured to move (being on two straight lines in embodiment illustrated) on the straight line of almost parallel all in the equidirectional alignment, thereby the configuration of cable wire class and uncomplicated and be simplified.In addition, like this, because the configuration of cable wire class is easy, thereby the structure of rice transplanter self also is simplified, in addition, ridge culture during already with the maintenance of the repairing of clutch unit 62 or mounting or dismounting etc. the cable wire class can not interfere, maintenance characteristics is also good.

Below, the rice transplanter of manned formula of eight of plantations is described.According to the rice transplanter of the manned formula of four of plantations shown in Figure 1, per two are provided with plantation with part clutch 51 (two altogether).In the rice transplanter of manned formula of eight of plantations, though plantation is identical with the rice transplanter of the manned formula of four of plantations with part clutch 51 itself, planting use part clutch 51 is 4.In addition; Even the occasion of rice transplanter in the manned formula of eight of plantations; Through with first seedling plantation cable wire 72a, second seedling plantation cable wire 72b of the action usefulness of seedling cultivation device 13 and send seedling band 6c action usefulness first send seedling cable wire 73a, second to send seedling cable wire 73b etc. to be configured to its length direction all to align at equidirectional; And be configured on (for example two) straight line of almost parallel, move; Self-evident, also can obtain and the identical action effect of occasion of rice transplanter of planting four manned formula.In addition, in this case, as long as on the left of already controlling with the ridge culture in left side 4, already control 4 of right side with the ridge culture on right side and get final product with clutch unit 62 with clutch unit 62.

The front section view (sketch) of Fig. 8 (a) expression seedling case 6, the figure that Fig. 8 (b) expression is seen from the inboard of seedling case 6.

And; Top at seedling case 6 is provided with fixed prolongation seedling case 96 to each bar; Making folding occasion these being prolonged seedling casees 96, be suitable for adopt make DYN dynamic ridge culture already use clutch unit 62 (with shown in Figure 6 identical) to prolong seedling case 96 about the outside configuration of exposing.

In seeding transplant machine in recent years,, be provided with fixed prolongation seedling case 96 on the top of seedling case 6 for many seedlings are loaded on the seedling case 6.In addition, the left and right sides width of seedling case 6 is broad also, make when folding and unfolding with separate projecting strip part 6d (Z of Fig. 8 (b)) with about the outside carry the folding to the inside structure of the 6e of seedling portion.That is, the left and right sides width of the seedling case 6 during with folding and unfolding is compared, and be provided with to carry the 6e of seedling portion in the left and right sides outside to each grid, is provided with above that and carries the 6e of seedling portion.

For prolonging seedling case 96, on the spatial relationship in the folding and unfolding place of seeding transplant machine, also make the structure that can not interfere in order to prolong seedling case 96, thereby with about the prolongation seedling case 96 of bar in the outside make the structure that folds to the inside.

For example, shown in Fig. 8 (a), the prolongation seedling case 96 of right ends rotates folding and unfolding in the inboard with fulcrum 96a for middle mind-set arrow E direction.When this state (prolonging the folding state of seedling case 96), DYN dynamic ridge culture already is configured to than the left end of prolongation seedling case 96 or right-hand member more in the outer part with clutch unit 62.In addition, through with about the seedling portion 6 of carrying in the outside projecting strip part 6d is folding to the inside to make ridge culture already also be in opening-wide state with the back side of clutch unit 62 to separate.

Through adopting this structure, when the maintenance of clutch unit 62 is already used in ridge culture, prolong seedling case 96 and carry the 6e of seedling portion and can not interfere each other, can also carry out operation from the top of seedling case 6 or the rear side of fuselage, maintenance characteristics improves.

What Fig. 9 represented is the other example (reference example) that clutch unit 62 is already used in ridge culture, expression be the stereogram of the servomotor of motor when having used servomotor 90.

In addition; Action that also can be through each bar on the rotating shaft that changes motor is with the number of turns (phase deviation) of steel wire 91,92,93,94, already uses the interior motor of clutch unit 62 (with shown in Figure 6 different) to make the servomotor 90 of rotating speed of the rotating shaft of controlled motor ridge culture.

That is, make correspondingly with the rotating speed of the rotating shaft 90a of servomotor 90, each steel wire 91,92,93,94 of tractive and make its action makes the structure of the plantation of each bar with 51 disconnections of part clutch successively.In addition, sending the steel wire of seedling with part clutch 53 (not shown) to be configured to and to plant steel wire with part clutch 51 retracts on the contrary and gets final product.

And; For example; To be used for first, second the plantation of transmission of the driving section 50a of branch of break-make and make the number of turns+3 circles with first, second steel wire 91 of part clutch 51; To be used for break-make the 3rd, the 4th the plantation of transmission of the driving section 50a of branch is made the number of turns+1 circle with the 3rd, the 4th steel wire 92 of part clutch 51; To be used for break-make the 5th, the 6th the plantation of transmission of the driving section 50a of branch is made the number of turns-1 circle with the 5th, the 6th steel wire 93 of part clutch 51; To be used for break-make the 7th, the 8th the plantation of transmission of the driving section 50a of branch is made the number of turns-3 circle with the 7th, the 8th steel wire 94 of part clutch 51, and be wound on the rotating shaft 90a of motor.And, make through the electric machine rotational axis 90a with motor 90 make the rotation 4 the circle more than break off the structure of the plantation of whole bars with part clutch 51.

About the situation of the steel wire of the rotating speed of at this moment motor 90 and action is shown in table 2.

Table 2

When motor 90 is just changeing (arrow G direction) (left side of table 2), the rotation speed n of motor 90 is more than 0 and less than 1 o'clock, and the steel wire of action is zero; The rotation speed n of motor 90 is more than 1 and less than 3 o'clock, and first, second steel wire 91 is the above and action of 4 (3+1=4) circle, and first, second plantation is broken off with part clutch 51.And; The rotation speed n of motor 90 is more than 3 and less than 5 o'clock; Except that first, second steel wire 91, the 3rd, the 4th steel wire 92 is the above and action of 4 (1+3=4) circle, first, second plantation with part clutch 51 and the 3rd, the 4th plantation with 51 disconnections of part clutch.The rotation speed n of motor 90 is more than 5 and less than 7 o'clock; Except that first, second steel wire 91, the 3rd, the 4th steel wire 92; Also through the steel wire 93 that makes the 5th, the 6th be 4 (1+5=4) the above and action of circle, then first, second plantation with part clutch 51 and the 3rd, the 4th plantation with part clutch 51 and the 5th, the 6th plantation with 51 disconnections of part clutch.And, if the rotation speed n of motor 90 is more than 7, then through the steel wire 94 that makes the 7th, the 8th also be 4 (3+7=4) the above and action of circle, then all steel wires 91,92,93,94 actions and all plantation with 51 disconnections of part clutch.

On the other hand, during motor 90 counter-rotating (direction in the opposite direction with arrow G) (right side of table 2), the rotation speed n of motor 90 be greater than-1 and 0 when following, and the steel wire of action is zero; The rotation speed n of motor 90 is greater than-3 and-1 when following, and (3-1=-4) the above and action of circle, the 7th, the 8th plantation is with 51 connections of part clutch to an opposite sideway swivel 4 for the 7th, the 8th steel wire 94.And; The rotation speed n of motor 90 be greater than-5 and-below 3; Except that the 7th, the 8th steel wire 94; Five, the 6th steel wire 93 to an opposite sideway swivel 4 (1-3=-4) the above and action of circle, then the 7th, the 8th plantation with part clutch 51 and the 5th, the 6th plantation with 51 connections of part clutch.The rotation speed n of motor 90 be greater than-7 and-below 5; Except that the 7th, the 8th steel wire 94 and the 5th, the 6th steel wire 93; Also through make the 3rd, the 4th steel wire 92 to an opposite sideway swivel 4 (+1-5=-4) the above and action of circle, then the 7th, the 8th plantation with part clutch 51 and the 5th, the 6th plantation with part clutch 51 and the 3rd, the 4th plantation with 51 connections of part clutch.And if the rotation speed n of motor 90 be below-7, the steel wire 91 through making first, second also (+3-7=-4) the above and action of circle, then all connect with part clutch 51 to an opposite sideway swivel 4 by steel wires 91,92,93,94 actions and whole the plantation.

Like this; Owing to can operate steel wire 91,92,93,94 with the easy structure that does not have motion arm 80a as shown in Figure 6,80b; Even not manually to operate, also can automatically carry out the break-make of the plantation of each bar successively, thereby the plantation operating efficiency improves with part clutch 51.

In addition, can adjust at an easy rate through the diameter of change motor shaft 70a or the length of steel wire 91,92,93,94 with the action of the corresponding steel wire 91,92,93,94 of the rotating speed of motor 90.

Figure 10 (a) expression be the vertical view of soft or hard sensor 100 that is used to measure the hardness in field, Figure 10 (b) expression be the end view of the soft or hard sensor 100 of Figure 10 (a).In addition, soft or hard sensor 100 is configured between the whole ground rotor 27a at whole ground rotor 27b and rear in the place ahead (near the W of Fig. 1).

Shown in Figure 10 (a); At one end portion's other end of being connected the support arm 109 on the driving shaft of whole ground rotor 27a swings up and down the leading section that is supported with arm 107 freely through turning cylinder 109a; The rotation of the other end of arm 107 is connected with the rotating shaft 101a of the rotary body 101 of drum type freely, and this rotary body 101 possesses the horizontal wide ground plane with regulation.Two rotary bodies 101,101 rotate on the same axle center of rotating shaft 101a integratedly.And the rotating speed detecting sensor 105 that detects the rotating speed of rotary body 10 is arranged on rotating shaft 101a part.

Rotary body 101 can get in the topsoil face in field because of deadweight in rotation.

And if utilize rotating speed detecting sensor 105 to detect rotary body 101 not rotate, it is hard then to be judged as the field.If the field is hard, then earth rotates attached to being difficult on the rotary body 101 owing to topsoil is sticking.On the other hand, if the field is soft, then earth is difficult to attached on the rotary body 101 because topsoil is not sticking, and what influence rotation is not had.

Use rotating speed detecting sensor 105 to constitute soft or hard sensor 100 through the rotation that utilizes such rotary body 101, thereby can utilize rotating speed detecting sensor 105 to measure the swing of rotary body 101, and measure the hardness in field at an easy rate.Therefore, can carry out the plantation operation that the hardness with the field matches, thereby improve operating efficiency.For example, determining the hard occasion in field, the control sensitivity of seedling being planted the up-down control of portion 4 is provided with bluntly.In addition, determining the soft occasion in field, the control sensitivity of seedling being planted the up-down control of portion 4 is provided with responsively.

Then; Shown in Figure 10 (b); Between arm 107 and support arm 109, be provided with the load measurement sensor 103 of measuring the load be applied to 109 on this arm 107, support arm, in the plantation operation; At this arm 107,109 loads that apply of support arm, judge the adhesion condition of earth when measuring 4 risings of seedling plantation portion.If earth is attached on the rotary body 101, then rotary body 101 becomes heavy and sinks and sink in the earth.And if sink in the earth, then rotary body 101 is difficult to rotation, and it is hard that this situation then is judged as earth.Like this, compare judgement with the original hardness in field hard, can not detect hardness exactly.Compare with it, this structure is controlled thereby carry out revisal for the hardness that detects soil exactly through load measurement sensor 103 is set.That is, make load become heavy if adhere to earth, then get its revisal softer.

Judge the adhesion condition of earth through measuring the load that on the linkage of this arm 107, support arm 109, applies when seedling plantation portion 4 rises; Thereby the detected value to soft or hard sensor 100 (rotating speed detecting sensor 105) carries out revisal; Specifically; The occasion that the measured value of load measurement sensor 103 is big (load heavy occasion), it is softer how many sensor values revisals of soft or hard sensor 100 to be got according to measured value, thereby can measure exactly.

In addition, Figure 11 (a) expression be the simple vertical view of soft or hard sensor 120 of other example that has utilized the soft or hard sensor 100 of rotary body shown in Figure 10 101, Figure 11 (b) is the schematic side view of Figure 11 (a).

Soft or hard sensor 120 as the other example of the rotary soft or hard sensor 100 that has utilized rotary body shown in Figure 10 101 and rotating speed detecting sensor 105; Shown in figure 11; Also can be that the place ahead is the V font (perhaps also can be the U font) of prominent shape when overlooking, the spring 120a of the shape of serving as reasons during side-looking, the V font soft or hard sensor 120 that 120a constitutes with tabular planar portions.In addition, the barred body 120b of V font teat (connecting portion of spring 120a, 120a) is connected on the transmission case (not shown) of whole ground rotor 27b.

The structure of V font soft or hard sensor 120 shown in Figure 11 does; Integral body is spring-like; Earth through utilizing the surface, field pushes from the left and right directions outside; Thereby the spring 120a about making, 120a are fulcrum crooked (closing) to the inside with barred body 120b, and utilize this power of closing (power that spring 120a, 120a are applied) to measure the hardness in field.

Detect with the angular transducer (not shown) that is arranged on barred body 120b part and to be applied to the last power of spring 120a, 120a to measure; If the power that spring 120a, 120a are applied is bigger; It is harder then to be judged as the field, if the power that spring 120a, 120a are applied is less, it is softer then to be judged as the field.

And it constitutes, even the travel speed of rice transplanter is very fast, so long as spring 120a, the 120a of soft or hard sensor 120 do not close to the inside, then travel speed is carried out automatic deceleration control.

The vehicle speed sensor (not shown) of the travel speed of measuring rice transplanter is arranged on the part to the power transmission shaft 11a of trailing wheel 11; And control device (not shown) is set; Detected value according to vehicle speed sensor; The speed of a motor vehicle reaches certain above occasion; If spring 120a, the 120a of soft or hard sensor 120 do not close to the inside, promptly be judged as power that spring 120a, 120a are applied hour according to the detected value of soft or hard sensor 120, this control device is controlled the travel speed of rice transplanter also slower than present travel speed.

In the fast occasion of the travel speed of rice transplanter, if soft or hard sensor 120 does not cut out to the inside, then because of soil is soft excessively, the earth that is caused by buoyancy aid 14 grades pushes violent.

Therefore, through adopting this structure, in the fast occasion of the travel speed of rice transplanter, when soft or hard sensor 120 did not cut out to the inside, through the reduction travel speed, thereby the earth that can suppress to be caused by buoyancy aid 14 grades pushed.

Figure 12 representes is the rear of the buoyancy aid 14C at the center of Fig. 1 schematic side view when being provided with buoyancy aid sensor 130.

As stated; Each buoyancy aid 14C, 14L, 14R rotate with connecting portion 129 and are installed on the fuselage freely; The concavo-convex front that makes accordingly with field topsoil face moves up and down, and utilizes anterior the moving up and down of the not shown buoyancy aid 14C of angle of attack sensor inspection center during the plantation operation.

According to the testing result of plantation angle of attack sensor during operation, the hydraulic valve V (Fig. 2) through the above-mentioned lifting hydraulic cylinder 46 of switching controls goes up and down seedling plantation portion 4, thereby the planting depth of seedling is always kept necessarily.And; Different with this testing agency that moves up and down; The rear of buoyancy aid 14C is provided with buoyancy aid sensor 130 at the center; Also be provided with when detecting field topsoil face concavo-convex by this buoyancy aid sensor 130, make the control device (not shown) of the control that the sensitivity of the testing agency that moves up and down slows up.That is, this buoyancy aid sensor 130 is to be used to move up and down the device of revisal of sensitivity of testing agency.

Shown in figure 12, through the rear portion of the buoyancy aid 14C at the center potentiometer 130a is installed, connect the leading section of the small-sized buoyancy aid 130b at potentiometer 130a and buoyancy aid 14C rear, center, thereby can constitute buoyancy aid sensor 130 at an easy rate.

The concavo-convex occasion of topsoil face in the field, if the sensitivity of buoyancy aid sensor 130 is very sensitive, then reaction has surpassed required and has had the situation of the plantation operation being brought obstacle.The swing of for example, going up and down because of seedling plantation portion 4 sometimes causes planting depth inappropriate.

Therefore,, make the up-down control of seedling plantation portion 4 stable, make planting depth suitable, thereby can carry out appropriate plantation operation through adopting this structure.

Figure 13 representes is the end view of soft or hard sensor 140 of other example that has utilized the soft or hard sensor 100 of rotary body shown in Figure 10 101

In addition, also the soft or hard sensor 140b that is made up of the turn-sensitive device that utilizes rotary body can be set on the buoyancy aid 14C of center, and these two sensors of the soft or hard sensor 140a that has only potentiometer 141 that do not utilize rotary body.

Shown in figure 13; The fore-and-aft direction that also can make on the buoyancy aid 14C of center is provided with a plurality of potentiometers 141,141; One side's potentiometer 141 is an original state, and the opposing party's potentiometer 141 is provided with rotary body 142, thereby becomes the soft or hard sensor 140 that is made up of diverse a plurality of sensors.

Be used to measure from the detected value of the soft or hard sensor 140 of this structure the hardness in field, judgement is harder sandy or softer earth, and utilizes control device (not shown) that revisal is carried out in the hydraulic pressure sensitivity of lifting hydraulic cylinder 46.For example, be judged as firmly, and be judged as harder sandy in the many occasions of rotating speed with the soft or hard sensor 140b that constitutes by turn-sensitive device with the soft or hard sensor 140a that does not utilize rotary body.In addition, be judged as firmly, and be judged as the earth matter of some firmly in the few occasion of rotating speed with the soft or hard sensor 140b that constitutes by turn-sensitive device with the soft or hard sensor 140a that does not utilize rotary body.

Be harder sandy occasion because relatively the earth pushing is more with harder earth matter, thereby with harder earth matter relatively, establish the hydraulic pressure sensitivity of lifting hydraulic cylinder 46 responsive.On the other hand, when soil is softer, irrespectively set sensitivity with sandy, earth matter.

Testing result according to soft or hard sensor 140; Hydraulic valve V through the above-mentioned lifting hydraulic cylinder 46 of switching controls goes up and down seedling plantation portion 4; Thereby the planting depth of seedling is always kept necessarily, but utilized said structure, through adopting to the best hydraulic pressure sensitivity in field; Suitable earth pushing can be realized through the control of precision, stable up-down control can be carried out.

Have again, owing to can be suitable for the control of lifting hydraulic cylinder 46 of the lifting hydraulic cylinder 46 in field, thereby the planting depth of the seedling that can will be obtained by the up-down of seedling plantation portion 4 is always kept necessarily.

Figure 14 (a) expression be the vertical view of soft or hard sensor (width sensor) 150 of other example that has utilized the soft or hard sensor 100 of rotary body shown in Figure 10 101, Figure 14 (b) expression be the end view of Figure 14 (a).In addition, Figure 14 (a) has omitted the diagram of the connecting portion of trenching implement 64 and width sensor 150.

And, also can make at the rear of the trenching implement 64 of rice transplanter shown in Figure 1, the device of the situation of measuring the ditch that landfill forms by trenching implement 64 is set, thus the structure of the hardness in mensuration field.

Shown in Figure 14 (a), be connected with at the rear of trenching implement 64 and have the width sensor of overlooking to U font (also can be the V font), the width width B narrower 150 than the horizontal wide A of trenching implement 64.Width sensor 150 is shown in figure 11, and the place ahead is the U font (perhaps, also can be the V font) of prominent shape when overlooking, and spring 150a, 150a that the side has the shape of tabular planar portions when seeing constitute.And shown in Figure 14 (b), an end of the fork-shaped support arm of seeing in the side that is connected in the fuselage side 151 is connected with the leading section of trenching implement 64, is connected with width sensor 150 in the other end of fork-shaped support arm 151.In addition, the barred body 152 of the teat of width sensor 150 through being arranged at the U font is connected on the fork-shaped support arm 151.

Though the ditch that is formed by trenching implement 64 gradually by landfill, through utilizing the furrow width after width sensor 150 is measured ditchings, can be known the landfill that has carried out what degree.Because this width sensor 150 is likewise made spring-like with the soft or hard sensor 120 of Figure 11; Thereby through utilizing the surperficial earth in field from the pushing of the left and right directions outside; Thereby the spring 150a about making, 150a are center crooked (closing) to the inside with barred body 152, and utilize this power of closing (power that spring 150a, 150a are applied) to measure the hardness in field.Detect power that this spring 150a, 150a are applied to measure with the angular transducer (not shown) that is arranged on barred body 152 parts.

For example; In the occasion that detects wider width with width sensor 150; Promptly almost do not having the occasion of returning (landfill of ditch) of earth, it is harder to be judged as the field, is detecting the narrower occasion of width with width sensor 150; Promptly earth return (landfill of ditch) occasion faster, it is softer to be judged as the field.

Therefore, owing to adopt this structure, through measuring the furrow width that forms by trenching implement 64, thereby the situation of returning of earth can be known, the hardness in field can be measured with easy structure with width sensor 150.

In addition, width sensor 150 shown in Figure 14 is through first ditching, judges the device of the soft or hard of soil again according to the soil amount of returning this ditch, in this with only be conceived to because of the advance soft or hard sensor 120 of Figure 11 of resistance of the soil that causes of fuselage be different.

And, have again, control device (not shown) also can be set, this control device is judged as the slower occasion of returning of earth at the detected value according to width sensor 150, automatically makes the slack-off control of travel speed of rice transplanter.In the slower occasion of returning of earth, the field is harder owing to being judged as, thereby if the travel speed of rice transplanter is fast, then seedling plantation portion 4 is in the state that floats, and is easy to generate floating seedling.In addition, be easy to generate floating seedling owing to the earth time of return is not abundant.And so-called floating seedling is meant and makes the seedling phenomenon that surface floating is got up from the field owing to the plantation of seedling is insufficient.

Therefore; Owing to adopt this structure, in the slower occasion of returning of earth, through automatically reducing the travel speed of rice transplanter; Thereby can make earth that abundant time of return is arranged, can promote returning of earth and avoid producing floating seedling and can plant normally.

What Figure 15 represented is the partial side view when on the buoyancy aid 14C of the center of rice transplanter shown in Figure 1, planting depth motor 160 being set.

In addition, be judged as the slower occasion of returning of earth, also can adopt the structure of automatically planting deeply at detected value according to width sensor 150.

Be judged as the slower occasion of returning of earth, through making planting depth motor 160 actions that are connected on the buoyancy aid 14C of center by means of linkage R center buoyancy aid 14C moved up and down (amplitude that moves up and down is represented with α), and deepen the planting depth of seedling.If the motor shaft 160a of planting depth motor 160 is middle mind-set arrow b1 direction rotation with the gear 160b meshed gears 161 that is arranged on the motor shaft 160a with fulcrum P then to the rotation of arrow a1 direction.And center buoyancy aid 14C moves to the top to the action of arrow c1 direction with (linkage) L of bindiny mechanism of center buoyancy aid 14C through the back shaft 162 by means of gear 161.In addition, if the motor shaft 160a of planting depth motor 160 is middle mind-set arrow b2 direction rotation with the gear 160b meshed gears 161 that is arranged on the motor shaft 160a with fulcrum P then to the rotation of arrow a2 direction.And center buoyancy aid 14C moves downwards to the action of arrow c2 direction with the L of bindiny mechanism of center buoyancy aid 14C through the back shaft 162 by means of gear 161.

Adopt this structure, through changing the up-down degree of seedling plantation portion 4, and can adjust the planting depth of seedling with matching with the degree of depth of this ditch.

What Figure 16 represented is the release structure chart regularly that utilizes planting tool for seedling 22 change seedlings.

Have, the situation that the earth that obtains according to the detected value from width sensor 150 returns also can adopt the structure of the action cycle of automatically changing planting tool for seedling 22 again.

Change mechanism between the strain of action cycle, be provided with change handle 36 between the strain that is used to carry out alter operation between strain below the hood shown in Figure 1 32 as change planting tool for seedling 22.But, the control device (not shown) automatically change according to the release control regularly of the seedling of planting tool for seedling 22 preferably is set.Because the release of seedling is to be moved by the active force of releasing spring (not shown), thereby timing responsiveness according to planting tool for seedling 22 in the plantation movement locus that release finishes has some variations.

According to this embodiment, make the phase place that changes the fixing central gear that makes revolving planting tool for seedling 22 actions according to the rotation of the metalwork 163 of driver 165.Release structure regularly to change.

For example, be judged as the slower occasion of returning of earth, preferably automatically accelerate the release timing of the seedling of planting tool for seedling 22 at detected value according to width sensor 150.Release through accelerating seedling is regularly deepened plantation and is prevented floating seedling.In the slower occasion of returning of earth, if the action of planting tool for seedling 22 is very fast, then the release of seedling regularly becomes floating seedling slowly.If the release of seedling is regularly slow, even then become floating seedling because release has also been played the release effect in the higher position of native face.In addition, be judged as the occasion faster of returning of earth at detected value according to width sensor 150, even because how many more shallow plantations, returning of earth is also fast, thereby also is difficult to produce floating seedling.

Therefore, through adopting this structure, the returning situation of earth that can obtain according to detected value from width sensor 150 and automatically change planting tool for seedling 22 seedling release regularly, thereby can prevent to produce floating seedling.
