Then, the structure of clutch linkage mechanism that switches to the state of " disconnection " to being used to make this unit clutch 78 and ridge to end clutch linkage describes.Figure 21 is the stereogram that expression will be scattered the scaffold of the state of having pulled down the unit.Shown in Figure 21 like this, rotatably support frame side clutch lever (frame side contact component) 185 on framework 53.This frame side clutch lever 185 and four distribution unit u are provided with accordingly.

Therefore, four frame side clutch levers 185 are set on the framework 53 of this embodiment.In addition, on each frame side clutch lever 185, connecting the end that clutch operating power is transmitted metal wire (clutch operating force transmission member) 186 respectively.And separately clutch operating power is transmitted the other end of metal wire 186, and is shown in figure 16, is attached on the clutch operating pin 157 that the corresponding electronic housing 37 of plantation possesses.Through this structure, can frame side clutch lever 185 be rotated through the displacement of clutch operating pin 157.

In addition, here " corresponding the electronic housing 37 of plantation " is meant the electronic housing 37 of the plantation corresponding with the position of scattering unit u.For example, the frame side clutch lever 185 that is provided with accordingly with leftmost distribution unit u transmits metal wire 186 through clutch operating power and links with the clutch operating pin 157 that the electronic housing 37 of leftmost plantation possesses.In addition, for example, play second with a left side and scatter frame side clutch lever 185 that unit u is provided with accordingly and transmit metal wire 186 and a left side through clutch operating power and play the clutch operating pin 157 that second electronic housing 37 of plantation possess and link.

Therefore; As if the arbitrary velamen operation among the stopping bar in four ridges; The clutch operating pin 157 of the corresponding electronic housing 37 of plantation is pushed into this and plants in the electronic housing 37; Then clutch operating power transmission metal wire 186 is passed to corresponding with it frame side clutch lever 185 with the displacement of this clutch operating pin 157, and this frame side clutch lever 185 is rotated.That is, constitute and to make the ridge end the operation of clutch and the action of frame side clutch lever 185 links.

In addition, Figure 22 is the stereogram that scatters the unit, and Figure 23 is the stereogram from the distribution unit that the angle that is different from Figure 22 is seen.Shown in these Figure 22～23, on the plate-shaped member 128 that scatters unit u, be rotatably mounted cell side clutch lever (cell side contact component) 180.Cell side clutch lever 180 is made up of clutch components abutting part 181 and operation inputting part 182.

Clutch components abutting part 181 be configured to can with the flange part 149a butt of the periphery that is formed on cell side clutch components 149.Operation inputting part 182 is constituted as tabular position, and is fixed on above-mentioned clutch components abutting part 181.Can cell side clutch lever 180 be rotated in prescribed direction through push away this operation inputting part 182 to prescribed direction.

And, constituting and can rotate in prescribed direction through cell side clutch lever 180, clutch components abutting part 181 pushes away cell side clutch components 149, makes this cell side clutch components 149 to the direction displacement of leaving frame side clutch components 176.In view of the above, can make unit clutch 78 become the state of " disconnection ".

Also shown in figure 20, constitute and installing under the state that scatters unit u, the position that the operation inputting part 182 that becomes cell side clutch lever 180 and frame side clutch lever 185 are approaching.And if stopping bar is operated in the ridge, then corresponding with it frame side clutch lever 185 rotates, and contacts the operation inputting part 182 of the approaching cell side clutch lever 180 of this frame side clutch lever 185, pushes away this operation inputting part 182 to prescribed direction.

In view of the above; Constituting cell side clutch lever 180 rotates; Clutch components abutting part 181 pushes away cell side clutch components 149, and the position that makes this cell side clutch components 149 is to the direction displacement of leaving from frame side clutch components 176, and can unit clutch 178 be cut off.That is, constitute and to make the ridge end clutch to link with corresponding cells clutch 178.

In addition, as stated, the ridge termination clutch of planting electronic housing 37 is can make according to per two ridges to plant the structure that stops.On the other hand, scatter unit u is emitted cylinder 125 by two of drive shaft (two ridges amount) structure.Therefore, can stop the driving that two (two ridges amounts) are emitted portion 55 by a unit clutch 178.

According to being such structure, end clutch and unit clutch linkage through making the ridge, can switch plantation and having or not of case applied agents distribution according to per two ridges.In addition, through constituting in the above described manner, and emit the structure that portion 55 is provided with a unit clutch with respect to one and compare, can cut down the quantity of part of the association of unit clutch, can constitute simply and scatter unit u and drive transmission mechanism.

Then, explain that be used for can be with scattering the structure that unit u pulls down from framework 53.As stated, unit clutch 178 constitutes as the engaged clutch that is made up of cell side clutch components 149 and frame side clutch components 176.And cell side clutch components 149 can leave from frame side clutch components 176.

That is, can the drive transmission mechanism of the part of emitting driving shaft 148 clutch 178 in the unit that scatter unit u from framework 53 sides be cut off.Like this, through unit clutch 178 is constituted as engaged clutch, will scatter unit u when framework 53 is pulled down, need not be used to transmit driving mechanism pull down operation etc., therefore, can this distribution unit u be pulled down simply.

In addition, as stated, cell side clutch lever 180 only is closely to dispose each other with frame side clutch lever 185 (being not that mechanicalness links).Therefore, cell side clutch lever 180 is left from frame side clutch lever 185.In view of the above, will scatter unit u when framework 53 is pulled down, need not be used to transmit clutch operating power mechanism's (for example metal wire etc.) pull down operation etc., therefore, can this distribution unit u be pulled down simply.

In addition, in case applied agents spreading machine in the past, can not the portion of emitting be cut off from the drive transmission mechanism of frame side simply, so, can not the dispersion loading hopper be pulled down as the concentrated area, unit with the portion that emits.Therefore, in case applied agents spreading machine in the past, in order can remaining medicament in scattering loading hopper easily to be discharged, therefore making only can be with scattering the structure that loading hopper is pulled down.In this structure, existence can not link scattering loading hopper and emitting between the portion securely, and rainwater is invaded the situation of medicament stripping from the gap of scattering loading hopper and emit between the portion.In addition, owing to the portion of emitting can not pull down from framework, so, can not easily easily discharge remaining in this medicament of emitting portion inside.

Aspect this, in this embodiment, through above-mentioned constitute suchly scatter unit and drive transmission mechanism, can easily the portion of emitting 55 be cut off from the drive transmission mechanism of framework 53 sides.Therefore, can be with dispersion loading hopper 54, emit portion 55, chute 147 etc. and concentrate integratedly, constitute and scatter unit u, each this distribution unit u can pull down from framework 53.

Therefore, in the structure of this embodiment, in order and to emit remaining medicament discharge in the portion 55 at dispersion loading hopper 54, pull down as long as will scatter unit u, 54a opens with cap, and reversing according to each this distribution unit u gets final product.Therefore, there is no need the case applied agents spreading machine as in the past, the dispersion loading hopper can be separated from the portion of emitting simply.Therefore, in this embodiment, dispersion loading hopper 54 is with to emit housing 55aa (55ab) fastening by screw.Like this, can with dispersion loading hopper 54 with emit housing 55aa (55ab) and links securely, so, and compared in the past, sealing improves, and can make rainwater etc. be difficult to invade inside.

Then, explain and be used for each is scattered unit u to the fixing structure of framework 53.Shown in figure 21, on framework 53, disposing the installation strut 187 that is used to put distribution unit u respectively in each installation site of scattering unit u.Each installs strut 187 by two foots 188 that are provided with side by side at the car body left and right directions with flatly constitute across the tabular horizontal part 189 between the foot 188.

On the other hand, like Figure 22 and shown in Figure 23, scatter pole parts 127 that unit u possesses and plate-shaped member 128 and be provided in car body left and right directions (direction parallel) respectively with emitting driving shaft 148.Be put into 187 last times of strut were installed should scattering unit u, pole parts 127 were placed on the foot 188, plate-shaped member 128 was placed on the horizontal part 189.In view of the above, can scatter unit u at three-point support at least by two foots 188 and horizontal part 189, so, can make the stable posture of this distribution unit u.

On the other hand, shown in figure 21, form rake 188a respectively and be formed on the U word 188b of portion of the lower end of this rake 188a continuously in foot 188.Through this structure, be placed on when strut 187 is installed will scattering unit u, keep pole parts 127 are connected to the former state of rake 188a, make and scatter unit u and move slidably downwards because of deadweight.

Like this, pole parts 127 are guided by above-mentioned rake 188a naturally, and these pole parts 127 embed the inboard of the U word 188b of portion, in view of the above, scatter unit u and are positioned at the car body fore-and-aft direction.And, constituting to scatter unit u under the state that the car body fore-and-aft direction has been positioned, clutch components 149,176 becomes opposed facing position.

In addition, horizontal part 189 and plate-shaped member 128 have the length to a certain degree on the car body left and right directions respectively.That is, staggered to a certain degree at the car body left and right directions, also can plate-shaped member 128 be placed on horizontal part 189 even scatter the position of unit u.On the other hand, the interval of two foots 188 is constituted as the length weak point than the car body left and right directions of pole parts 127.That is, staggered to a certain degree at the car body left and right directions, also can pole parts 127 be placed in two foots 188 even scatter the position of unit u.

Therefore; Even the pole parts were being put in foot 188 in 127 years; Plate-shaped member was put under the state of horizontal part 189 in 128 years, distribution unit u is moved to a certain degree at the car body left and right directions, also can scatter unit u 3 supportings stably at least by two foots 188 and horizontal part 189.That is, constitute the former state of posture that keep to scatter unit u, can make this distributions unit u in car body left and right directions (that is, clutch components 149,176 contact with each other or leave direction) slip.

Therefore, for example, under clutch components 149,176 state separated from one another, can stably be placed on temporarily and install on the strut 187 scattering unit u.Because unit u is scattered in can be so interim placement, so, the fitting operation of unit u can be scattered like a cork.And; Because under this interim state of placing (pole parts 127 embed the state of the U word 188b of portion); Scattering unit u is positioned at the car body fore-and-aft direction; So, this distribution unit u is slided at the car body left and right directions on installation strut 187, just can make clutch components 149,176 engagement simply each other.

The location of in addition, scattering the car body left and right directions of unit u can be carried out through making the protuberance 189a (referring to Figure 21) that is formed on horizontal part 189 embed hole portion 128a (referring to Figure 23) that is formed on plate-shaped member 128.In addition, near configuring fixed part 190 (referring to Figure 21) installation strut 187.This fixture 190 constitutes and can hook is fixed on the hook-like assembly unit 127a (referring to Figure 22) on the pole parts 127 and fixes.

And this fixture 190 constitutes and can switch hook hook-like assembly unit 127a and the state that stops and the state of having opened simply through singly touching (for example, with a finger).Therefore, after will scattering unit u location, fixture 190 is hooked on hook-like assembly unit 127a and stops, like this, can be simply be fixed on and install on the strut 187 scattering unit u.

As stated, only through stopping, can accomplish the installation of scattering unit u with fixture 190.And, only be installed on the framework 53 through scattering unit u, can become state that clutch components 149,176 has been engaged with each other (emitting the state that driving shaft 148 has been connected with drive transmission mechanism).Like this, needn't spend the time of the operating mechanism of the fastening or installing drive transmission mechanism of screw, clutch, can scatter the installation of unit u simply and pull down.

Then, explain and be used for carrying the structure put the seedling carrying base 31a that pulls down.Figure 24 is the rearview that the appearance of having put the seedling carrying base of pulling down is carried in expression.As stated, in this embodiment, constitute and can the seedling carrying base 31a of two ridges amount be separated from main seedling carrying base 31.On the other hand, shown in Figure 21 waits, on framework 53, be provided with to carry to put and scatter unit u and fixable interim placement strut 196.In addition, shown in figure 18, place strut 196 temporarily and be provided with two, be configured in the position that framework 53 leans on the car body left and right end portions respectively.

Make seedling carrying base 31a when main seedling carrying base 31 separates, at first, making four to scatter and lean on two of car body left and right directions central authorities to scatter unit u to move respectively and be fixed on the interim placement strut 196 among the unit u.In view of the above, can open the space at the position sky that leans on car body left and right directions central authorities.And, seedling carrying base 31a is separated from main seedling carrying base 31, be installed on the above-mentioned support column 197.And shown in figure 24, the seedling carrying base 31a that is installed on the support column 197 is configured in because of making two central distribution unit u move to the space that forms on the interim placement strut 196.

Separated seedling carrying base 31a is through being installed on the support column 197, and is configured in the top of remaining main seedling carrying base 31.And seedling carrying base 31a becomes when side-looking and scatters unit u position overlapped.Here, supposing that distribution unit u is moved, sky is opened under the situation in space, is necessary to be configured to seedling carrying base 31a and when side-looking, avoids overlapping (for fear of seedling carrying base 31a and distribution unit u interference) with distribution unit u.Therefore, in this case, the installation site of having to avoid scattering unit u and making seedling carrying base 31a is in high position, with the become difficulties such as operation of this seedling carrying base 31a to support column 197 installations.

Aspect this, in this embodiment,, distribution unit u is moved through above-mentioned that kind, form the space, can seedling carrying base 31a be installed in low position.In addition, owing to open the space at car body central portion sky, so when the fitting operation of this seedling carrying base 31a, scattering unit u can not become obstacle.And such structure is to constitute and can pull down simply from framework 53, the worst structure that can realize through scattering unit u.

As above state bright because can pull down with scattering unit u, so, for example, can the distribution unit u that pull down be reversed, the medicament that easily will remain in the inside of dispersion loading hopper 54 is discharged.And; Because can focus on dispersion loading hopper 54 integratedly and emit portion 55; So, constitute and can pull down the dispersion loading hopper with there is no need as medicament dissemination apparatus in the past from the portion of emitting, can improve dispersion loading hopper 54 and emit the sealing between the portion 55.Have again, can also take care of in advance according to each unit scattering under the state that unit u pulled down.

In addition; In the case applied agents dissemination apparatus 51 of this embodiment, will be delivered near the drive transmission mechanism that respectively scatters the unit u from the driving force that rice transplanter 1 takes out in configuration on the framework 53, will scatter unit u and be installed on the framework 53; Like this, driving shaft 148 and drive transmission mechanism are emitted in connection.In view of the above,, will emit driving shaft 148 and be connected drive transmission mechanism because be installed on the framework 53 through scattering unit u, so, can carry out simply scattering the operation that unit u installs to framework 53.

In addition, in the case applied agents dissemination apparatus 51 of this embodiment, each scatters unit u and possesses the cell side clutch components 149 that is fixed on an end of emitting driving shaft 148.On framework 53, scatter the frame side clutch components 176 that unit u configuration output drive transmission mechanism transmits the driving force of coming according to each.Through cell side clutch components 149 and 176 engagements of frame side clutch components, will emit driving shaft 148 and be connected with drive transmission mechanism.And cell side clutch components 149 can leave from frame side clutch components 176.

As stated, clutch is set accordingly, can scatters unit u according to each and switch having or not of the driving of emitting portion 55 through scattering unit u with each.And; Because through clutch is constituted as engaged clutch; Can will scatter unit u at the mate of cell side clutch components 149 and frame side clutch components 176 and cut off from framework 53, so, when the unit is pulled down; Need drive transmission mechanism not pulled down such time, can easily carry out this and pull down operation.

In addition, because engaged clutch is only through making clutch components 149,176 transmission of drive force that get final product closer to each other, so, only be installed to and can realize simply on the framework 53 emitting the structure that driving shaft 148 is connected with drive transmission mechanism through scattering unit u.

In addition, can scatter unit u slip, install or pull down this distribution unit u strut 187 being installed as guider, being made, so, can easily carry out clutch components 149,176 contraposition each other etc.And, can be through scattering unit u by fixture 190 is fixing, and become the state (being connected the state of emitting driving shaft 148 with respect to drive transmission mechanism) that cell side clutch components 149 and frame side clutch components 176 have meshed.

In addition, because can be by the posture that strut 187 keeps installing in the way or pulls down the distribution unit u in the way be installed, so, there is no need to scatter unit u and do not fall down and support installing or pull down in the operation with hand to making.In addition, can also be before fitting operation for example, will scatter unit u and be placed on for the time being temporarily and install on the strut 187.In view of the above, can more easily scatter the installation of unit u or pull down.

In addition, in the case applied agents dissemination apparatus 51 of this embodiment, can correspondingly make 149 displacements of cell side clutch components, clutch is switched with the operating physical force of clutch.Having, can be the boundary with the contact portion of cell side clutch lever 180 and frame side clutch lever 185 again, will scatter unit u and separate with framework 53.In view of the above, in the time will scattering unit u and pull down, such time is pulled down by the mechanism that does not have to be used for operated clutch, so, can easily carry out this and pull down operation.

In addition, in the rice transplanter 1 of this embodiment, can pull down, carry to put and place strut 196, and having the place sky of this distribution unit u to open the space originally interim through scattering unit u for the time being.And, the seedling carrying base 31a that the spatial configuration that can open at this sky is separated.

In addition, can also take in seedling carrying base is folding in the following manner.Figure 25 is the figure of the explanation action that the seedling carrying base of plantation portion is folding, and Figure 26 is that the A of Figure 25 is to view.Shown in Figure 25 like this, for example, seedling carrying base 31A～31H is grouped into four unit.That is, seedling carrying base 31A, 31B are first module, and seedling carrying base 31C, 31D are Unit second, and seedling carrying base 31E, 31F are Unit the 3rd, and seedling carrying base 31G, 31H are Unit the 4th.

In addition, seedling carrying base 31A～31H is bonded for lockup state through the connecting rod (locking rod) that makes separately edge portion respectively possess two.The support S of the tubulose of after the right border portion of the left border portion of seedling carrying base 31E and seedling carrying base 31F fixedly installs, stating in addition.Have again, possess the pin chimeric (jut) R respectively with the front end of support S in the left end the inside of seedling carrying base 31A and the right-hand end the inside of seedling carrying base 31B.Front end at this pin R and support S also possesses latch key (パ Star チ Application ingot), carries out locking by this latch key.

In addition, constitute the distribution unit 73A～73D respectively scatter unit u and carried and put on a series of framework 53, fixing by latch key etc.This framework 53 is supported in from four plantation transmission housings 37 and erects on the carriage that is provided with.This framework 53 possesses the maintaining part 53a same with above-mentioned strut 196.This maintaining part 53a is used for temporary transient carrying to put the parts that respectively scatter unit 73A～73D.

Then, to behind the rice transplanting EO, the first module (seedling carrying base 31A, 31B) of seedling carrying base 31A～31H is folding, and the method for the width of constriction seedling carrying base 31 describes.To be in Unit the 3rd ( seedling carrying base 31E, 31F) loading hopper unit 73C before and unload, carry (being in the below of loading hopper unit 73D) the maintaining part 53a put at this framework 53, fix by latch key from framework 53.

And, under the state that seedling carrying base 31A and seedling carrying base 31B have been bonded, remove the binding of seedling carrying base 31B and seedling carrying base 31C.Say that at length two connecting rods that the edge portion of seedling carrying base 31B is possessed rotate to the direction of removing, and remove the binding of seedling carrying base 31B and seedling carrying base 31C.Then, control the handle at the two ends that are in first module (seedling carrying base 31A, 31B), first module is moved.

And, first module is overlapped on Unit the 3rd ( seedling carrying base 31E, 31F).Say that at length two pin R that first module is possessed embed the front end (Figure 26) that is arranged on the pair of brackets S on Unit the 3rd respectively.Then, by not shown latch key locking.And the front end of the steady pin of the key shape that the left end of Unit the 3rd is possessed is fixed on the hole of the inside that is formed at first module.Then, it is folding the seedling that carries the part of having put first module to be taken out plate.Like this, the width of rice transplanter 1 reaches below the vehicle-width of running vehicle body 10.And, can there be the state of running vehicle body 10 and rice transplanter 1 to be loaded into truck etc. with binding, transport.

In addition, through oppositely carrying out above-mentioned step, can first module be launched from folded state.Therefore, detailed.

Then, on seedling carrying base 31, spread all over that the width of this seedling carrying base 31 is whole to possess the careless plate 60 of branch regionally.Figure 27 is the end view that possesses the plantation portion of the careless plate of branch, and Figure 28 is the end view that possesses the plantation portion of other routine careless plate of branch.This details of dividing careless plate 60 is shown in Figure 27 (a) and (b), by rectangle and have certain thickness metallic plate (flat board) and constitute (dividing careless plate 60 to be not limited to metallic plate, also can be the such article of plastic plate).This divides the both ends of careless plate 60 to be fixed on the upper end of the carriage 61 on the outer edge 31E that is fixedly set in seedling carrying base 31 with pin 62 grades.

In addition, hope to divide careless plate 60 with respect to carrying the length direction D that puts the seedling S on seedling carrying base 31 with angle [alpha] setting (being that opposition side at the moving direction of seedling S is provided with angle [alpha] obliquely in other words).This angle [alpha] is that the careless plate 60 of branch is open with the root of seedling S, easily with the angle of medicament P to the root supply of seedling S, and preferred 30～60 degree.

In addition, hope to divide the width W of careless plate 60 to set rightly according to the difference of carrying the length of putting the multiple seedling S on seedling carrying base 31.For example, consider seedling poor of excessive growth seedling and common growth, make the careless plate 60 of branch of W=50mm.So,, divide the also top of butt seedling S effectively of careless plate 60 even under the state that the seedling that upgrowth situation is different mixes, the root of seedling S is open, medicament is supplied with to the root of seedling S.

Then, the action of scattering medicament through the rice transplanter that constitutes like this to seedling is described.Transported downwards by moving belt B if carry the seedling S that puts on seedling carrying base 31, with minute careless plate 60 butts, then top forms the space to the carriage direction bent in root portion.Scatter unit u supplies with medicament P by this space by each to the root of seedling S.

And, if the fore-end of crooked seedling S leaves the lower end of the careless plate 60 of branch, then turn back to the state that erected originally.Like this, the seedling S on the seedling carrying base 31 is transported downwards one by one, begins bending successively from the seedling that abuts to the careless plate 60 of branch, forms the space at its root gradually.And, medicament P is supplied with to its root.

Figure 28 (a) and (b) are represented other example of the present invention.In this example, substitute a such branch grass plate of above-mentioned example, possess two excellent 80A of branch grass, 80B (dividing careless rod to be not limited to two, also can be more than three) abreast with certain interval L.In addition, the interval L of the excellent 80A of two branches grass, 80B is about L=50mm.Through dividing careless plate 60 to be replaced by the careless excellent 80A of branch, 80B, can the plantation portion of lightness be provided with same effect.

In this example, on the carriage 81 of the outer edge 31E that is fixedly installed on seedling carrying base 31, wait the two ends that fixedly install the careless excellent 80A of branch, 80B through welding.In addition, with regard to the action of scattering medicament P to seedling S, because of identical with above-mentioned example, so, omit explanation.
