Therefore, even if the position of the seedling accommodation body 26 at the time of the planting operation of the seedling planting body 6 on the seedling N shifts due to a shift at the time of assembling, the seedling planting body 6 is in the state of being moved to the lowermost end in the movement route, and Seedling container 26 in the same posture
Since the seedlings N can be planted, the change in the planting state can be minimized.

On the front side of the seedling conveying section 5, from the first case portion 32a of the planting transmission case 32 to the seedling table support frame 81.
A seedling table 82 is provided via the. The sweet potato seedlings are placed on the seedling placing table 82 in a storage box or the like, and the operator supplies the seedlings on the seedling placing table 82 to the upper lateral feeding section 5a of the seedling conveying section 5. To do.

On the rear side of the seedling conveying section 5, there is provided a gear shift lever 83 capable of stepwise shifting the traveling speed of the traveling device 4 by switching the transmission mechanism in the mission case 9.
It extends from the position of to the rear side. This seedling transplanter 1
Is a traveling device 4 for moving the machine body to the front, a seedling carrier 5 for carrying seedlings on a predetermined carrier route, a seedling plant 6 for planting the seedlings carried by the seedling carrier 5 in the field, and a rear part. Although the steering handle 2 is provided in the seedling carrier 5, the seedling carrier 5 is passed from the traveling device 4 through a space surrounded by the upper lateral feed part 5a, the lowering feed part 5b and the ascending feed part 5c of the seedling carrier part 5. A gear shift lever 83, which is an operation lever extending to the rear side, is provided. That is, the shift lever 83
It passes through a predetermined loop-shaped transportation path of the seedling transportation section 5.

Conventionally, there is a walking type sweet potato seedling transplanting machine in which a seedling planting body plants seedlings supplied by a worker who walks with the machine body in a field, and as shown in Japanese Patent Laid-Open No. 2001-16919, a front portion is used. A traveling device for traveling the machine body, a seedling transporting section for transporting seedlings through a predetermined transporting path, a seedling planting body for planting the seedlings transported by the seedling transporting section in a field, and a steering handle at the rear, An upper lateral feed unit that feeds the transport unit in one direction to the left and right on the upper side of the machine body, a lower feed unit that feeds the upper lateral feed unit downward, and a lower feed unit that feeds the upper lateral feed unit in the upward direction. There is a seedling transplanter configured with an ascending feed unit that returns to the feeding start end side, and when performing seedling planting work in the field, the machine is run by a traveling device and the worker traverses while the worker walks to the upper lateral feed unit. Supply seedlings to
It is designed to transplant sweet potato seedlings. Therefore, since the worker performs the work of supplying the seedlings to the upper lateral feed section of the seedling transport section while walking, the worker approaches the upper lateral feed section laterally or rearward of the upper lateral feed section. Will work. However, since the worker is located near the seedling transporting unit, an operating tool such as an operating lever is arranged at a position separated from the worker's position by the seedling transporting unit, such as in front of the seedling transporting unit. However, it becomes difficult to operate the operation tool while supplying the seedlings to the seedling transportation section, and there is a possibility that the operation tool cannot be easily operated. On the other hand, it is desirable that the seedling transport section has a long transport route so that a large number of seedlings can be accommodated because it is desirable for the operator to be able to perform seedling supply work with less fatigue in the seedling supply work. However, if the transport path of the seedling transporting section is lengthened, the seedling transporting section becomes large in size, which may hinder the ease of operation of the operation tool located at a position where the seedling transporting section is separated from the operator's position.

However, the shift lever 83, which is the operation tool of the present embodiment, has the feeding portions 5a, 5b, 5c of the seedling feeding portion 5.
Since it is configured to pass through the space surrounded by, the seedling transfer section 5 can be arranged at a position where the operator does not interfere with the operation, that is, the rear side of the seedling transfer section 5, and the operator transfers the seedling to the seedling transfer section 5. It can be operated easily while supplying, and seedling transplanting work can be performed comfortably.

A pair of left and right compression wheels 84 are provided behind the seedling plant 6. The crushing wheel 84 is a free wheel, and is designed to crush the soil above and to the left and right of the planted seedling that is grounded on the soil surface and supports the support frame 38.
It is provided at the rear end portion via a compression wheel frame 85. Therefore, by the grounding of the pair of left and right compression wheels 84,
Input shaft 3 of third case portion 32c of planting transmission case 32
The seedling planting body 6 and the seedling transporting section 5 which rotate around 3 are supported, and the seedling planting body 6 and the seedling transporting section 5 swing to follow the unevenness of the soil surface D to move a predetermined amount with respect to the soil surface D. It is designed to be maintained at the height. In addition, the seedling planting body 6 and the seedling conveying section 5
Since its own weight acts on the compression wheel 84, the compression wheel 84 can obtain a sufficient compression effect. In addition, as shown in FIG. 1, a compression wheel 84 is provided above the planting locus T of the seedling planting body 6.
Are arranged, and the positional relationship between the crushing wheel 84 and the planted seedling N is close to each other, so that the crushing wheel 84 is in close contact with each other, and the crushing effect can be properly obtained.

Therefore, in this sweet potato seedling transplanter, the machine is self-propelled by the traveling device 4 while straddling the ridge by the left and right front wheels 8 and the rear wheels 7, and the upper part of the self-propelled machine seedling transport section 5 of the machine. The sweet potato seedlings N are supplied from the operator behind the rear wheel 7 on the left side so as to walk the valley portion of the ridge through which the front wheel 8 and the rear wheel 7 on the left side pass. The seedling conveying section 5 conveys the supplied seedling N, and the seedling planting bodies 6 plant the seedling N transferred to the planting supply position A by the seedling conveying section 5 in the field.
The seedling transport section 5 includes a plurality of seedling containers 26 in the seedling transporting direction C, and the sweet potato seedlings N are housed in the seedling container 26 in such a posture that the vine t thereof is oriented in the front-rear direction. The operator supplies the seedlings N to the seedling container 26 that is conveyed in the left and right directions on the upper side of the machine by the upper lateral feed section 5a. However, the worker attaches the lower end of the vine t of the seedling N to the clip 49. The supplied seedlings are fixed to the seedling container 26. The seedling container 26 to which the seedlings have been supplied has an upper horizontal feeding section 5
Subsequent to a, it is conveyed downwardly of the machine body by the descending feed section 5b. Seedling container 2 conveyed by the descending feed section 5b
6 is conveyed to the upper side of the machine by the ascending feed section 5c and returns to the conveyance start end side of the upper lateral feed section 5a. Seedling plant 6
The seedling planting action part 6a is moved up and down by the drive part, and the seedling container N is stored in the seedling container 26 which is conveyed to the planting supply position A by the descending feed part 5b. Acting on the rear side of 26, plant seedlings in the field. At this time, the seedling N is sandwiched and fixed by the clip 49 of the seedling container 26, but since the sandwiching force of the seedling planting / holding tool 31 of the seedling planting body 6 is larger than the sandwiching force of the clip 49,
The vine t of the seedling N is detached from the clip 49 by the seedling planting body 6 moving the seedling rearward along the planting locus T.

Therefore, the seedling conveying section 5 supplies the seedlings between the fixed body 50 and the movable body 52 of the clip 49 of the seedling accommodating section 26 so as to be held and fixed, and the seedling accommodating body 26 is conveyed in a predetermined conveying path. The seedlings are transported by transporting in. When supplying seedlings between the fixed body 50 and the movable body 52, since the fixed body 50 is integral with the seedling container 26, the position of the fixed body 50 with respect to the seedling container 26 does not change. The work of supplying seedlings can be done easily. Further, since the seedlings can be supplied between the fixed body 50 and the movable body 52 while guiding the seedlings with the seedling guide portion constituted by the upper surface 50a of the fixed body 50 whose position does not change with respect to the seedling container 26, the clip 49 can be provided. The work of supplying seedlings can be easily performed. Therefore, since the work of supplying seedlings to the clip 49 can be easily performed, the work efficiency of the work of supplying the seedlings to the seedling container 26 by the worker is improved, and the seedling transport unit 3 is operated at high speed to improve the work efficiency of transplanting. Therefore, the work efficiency of the seedling transfer operation of the seedling transfer section 5 can be improved. In the conventional clip, since the pair of members for holding the seedlings are both constituted by the movable body, the position of the clip with respect to the seedling accommodation portion is deformed when the pair of movable bodies is deformed when the clip is supplied to sandwich the seedlings. It may change, and the clip may be transported along the transport path, which may make it difficult to supply seedlings to the clip. Further, if the seedling supplying work is troublesome, the work efficiency of the seedling conveying work of the seedling conveying device cannot be improved.

It should be noted that the fixed body 50 may be arranged on the lower side in the carrying direction of the carrying path with respect to the movable body 52 (on the right side in the upper transverse feed section 3a). As a result, the upper lateral feed section 5a
In, the seedlings are supplied from the lower side in the transport direction, that is, the fixed body 50 side, so that the worker can move the movable body 52 by using the transfer operation of the clip 49 only by pressing the seedling N on the upper surface of the fixed body 50. The seedlings N can be supplied between the fixed body 50 and the movable body 52, the seedlings can be easily supplied to the clip 49, and the work efficiency of the seedling conveyance work of the seedling conveyance section 52 can be improved. You can

As shown in FIG. 9, the fixed body 50 is connected to the rear end of the seedling container 26 so that the upper surface 50a is horizontal and is connected to the side plate portion 48, and the movable body 52 is the same as the upper surface 50a of the fixed body 50. It may be configured to have a horizontal upper surface 52c at a height. At this time, the upper surfaces 50 of both the fixed body 50 and the movable body 52.
a and 52c are the seedling guide portions.

In addition, as shown in FIG. 10, the fixed body 50 of the clip 49 is a bar member which is integrated with the seedling container 26 and is two front and rear members.
The movable body 52 is composed of a leaf spring whose upper end is attached to the seedling container 26 with two screws (screws) 51.
The lower end of the movable body 52 is positioned below the seedling accommodation body 26 and brought into contact with the clip actuating body 90 located below the seedling accommodation body 26 provided in the upper lateral feed section 5a, and the movable body 52 is forcibly fixed. It is to be moved to the opposite side of 50. Accordingly, when the operator supplies the seedlings to the seedling container 26 by the upper lateral feed section 5a, the holding portion of the clip 49 is open, so that the operation of supplying the seedlings to the clip 49 can be easily performed, and the seedling transporting device 5 It is possible to improve the work efficiency of seedling transfer work. When the seedling container 26 is conveyed from the upper lateral feed section 5a to the descending feed section 5b, the lower end of the movable body 52 separates from the clip operating body 90, so that the movable body 52, which is a leaf spring, moves to the fixed body 50 side. Then, the holding part of the clip 49 is closed,
The seedlings are automatically clamped and fixed. Upper transverse feed section 5a
A guide body 91 that guides the seedlings supplied to the seedling container 26 downward is provided at the transporting end portion of the so that the seedlings are fixed at appropriate positions by the clip 49. As a result, the seedlings can be reliably supplied to the planting supply position A, and stable seedling transplantation can be performed. As shown in FIG. 12, since the movable body 52 has a thin middle portion above the sandwiching position of the seedlings, the movable body 52 is easily bent and the opening amount of the clip 49 can be appropriately obtained by the clip operating body 90. You can

It should be noted that, as shown in FIG.
A leaf spring 52 on the fixed body 50 side is formed by stacking a number of leaf springs.
The other leaf spring 52e is made to project downward from the lower end of the leaf spring 52d on the side of the fixed body while making d the biasing force of the leaf spring 52e on the side of the fixed body smaller than that of the other leaf spring 52e. Only the clip actuating member 90 can force the upper lateral feed portion 5a to move to the opposite side of the fixed member 50. Accordingly, when the operator supplies the seedlings to the seedling container 26 by the upper lateral feed section 5a, the clamping force of the clip 49 acts only by the leaf spring on the fixed body 50 side,
The operator can easily supply the seedlings to the sandwiching portion of the clip 49 with a light force, and the operation of supplying the seedlings to the clip 49 can be easily performed. When the lower end of the other leaf spring 52e moves away from the clip actuating body 90, the two leaf springs 5 of the movable body are moved.
The clips 49 hold the seedlings with a large holding force at 2d and 52e, and the seedlings are reliably supplied to the planting and supplying position A, so that stable seedling transplantation can be performed. Therefore, when the seedlings are transported by the upper lateral feed section 5a, the seedlings are not at least displaced because the leaf springs 52d on the fixed body 50 side hold the seedlings.
The seedlings can be fixed at the appropriate position.

As shown in FIG. 24, the sweet potato seedling N is grown from the seed potato 92 of the sweet potato, which is the mother, and the vine t grows from the side of the seed potato 92 and the vine t grows. Lights such as the above are cast from above, so that each vine tends to concentrate and grow above the seed. At this time, seed 92
The bottom of the vine bends so that the buds that do not grow vertically from the vine grow upward, but since multiple vines are concentrated above the seed, the vine grows in an inclined state with respect to the vertical direction. The leaves 93 are concentrated on the upper side of the axis of the vine. Then, each vine separated and collected from the seed potato 92 becomes a seedling.

When transplanting the sweet potato seedlings, the operator fixes the lower end portion of the vine t of the seedlings to the clip 49 of the seedling container 26 in the upper transverse feeding portion 5a of the seedling feeding portion 5, and feeds it. If you supply it with the lower end of the vine t facing downward,
The seedlings are transported by the seedling transporting unit 5 and the lower end of the vine t faces upward at the planting supply position A, and the seedling leaves 93 face upward with respect to the vine. Then, the seedling planting body 6 is used to transplant the seedlings into the soil in the same posture. Therefore, the seedling plant 6
Since the transfer process of the seedlings into the soil is simple, it is difficult for the vine to bend and twist, improving the transplanting accuracy, and
It is possible to transplant sweet potato seedlings with the leaves concentrated toward the upper side of the tilted vine. In addition, since the pair of vertically extending seedling planting and sandwiching tools 31 sandwiches the lower end of the vine t that is bent upward in the state of being inclined forward at the planting supply position A, the vine t that is bent in the direction of the seedling planting and sandwiching tool 31. It is possible to make the state close to the vertical direction with respect to the direction of the lower end of the seedling, and even if the position of the seedling at the planting supply position A is slightly displaced, it is possible to ensure and stabilize the sandwiching of the seedling, and an appropriate posture. The seedlings can be planted at, and stable seedlings can be transplanted.

Therefore, the sweet potato seedlings N can be transplanted in a state where the leaves are intensively directed to the upper side with respect to the inclined vine t, so that the leaves 93 of the transplanted seedlings project out of the soil and the sunlight etc. Can receive the light of, and root growth is also vigorous, good growth can be performed, and sweet potato cultivation can be vigorous. Also, vine t
Since the direction of the leaf 93 with respect to the axis of the vine is determined and transplanted by the direction of the lower end of the vine, which is particularly easy to bend, this determination is facilitated, and the operation of supplying the seedling to the clip 49 can be performed easily and the operator's seedling The work efficiency of the seedling supply work to the container 26 is improved, the seedling transfer unit 5 can be operated at high speed to improve the transplant work efficiency, and the work efficiency of the seedling transfer work of the seedling transfer unit 5 is improved. be able to.

14 and 15 show a state in which different seedling planting and holding tools 31 are mounted. The seedling planting / holding tool 31 is provided with a protruding portion 31a whose middle portion is bent and protrudes to the front side (lower side). When the seedling planting / holding tool 31 is operated along a long and backward planting locus T, the projecting portion 31a moves largely back and forth in a state where the projecting portion 31a is located on the soil surface D in the side view of the machine body, but the lower portion of the projecting portion 31a. Is close to the soil surface D (front-back direction), so it does not collapse the soil up and down when it rushes into or out of the soil, and the planting holes in the soil can be kept small, making it suitable for transplanting seedlings. Can be In addition, when transplanting in a field where a mulch film is laid, the heat retaining effect can be favorably obtained without the holes of the mulch film for transplantation being unduly enlarged, and the seedlings can be cultivated well. If the seedling planting / holding tool is made linear, the soil planting holes and the holes of the mulch film are unnecessarily large, which may result in unstable seedling transplantation or poor seedling cultivation. In addition, since the seedling planting / holding tool 31 is formed of a round bar except for the plate-shaped portion 31b at the tip, it is difficult to catch the mulch film, and it is possible to prevent the hole of the mulch film from becoming too large.

In addition, the brush shown in FIGS. 14 and 15 is provided with a brush 94 which is inserted between the seedling planting and sandwiching fixtures 31 to remove dirt and the like from the sandwiching fixtures 31 for cleaning. The brush 94 is attached to a brush mounting arm 96 that is provided on the rear end portion of the support frame 38 and that swings about a rotation shaft 95 in the left-right direction. Provided brush operating roller 97
Is a brush operating arm 9 that is integral with the brush mounting arm 96
8 is lifted and the brush mounting arm 96 is moved upward, and in the process of raising the planting locus T of the seedling planting sandwiching tool 31, the sandwiching tool 31 is lifted.
It is designed to rush from the rear side in the meantime. This allows
A brush 94 or a brush is provided on the rear side of the seedling plant 6 so that the seedling planting fixture 31 that moves largely back and forth can be cleaned, and the swing link 37, the drive arm 34, and the actuation arm 42 of the seedling planting fixture do not interfere with the operation. The mounting arm 96 and the like can be arranged. If the brush 94 is configured to move together with the seedling plant 6, the seedling N may not be planted properly due to interference with other members or the seedling N held by the seedling planting / holding tool 31. is there.

As shown in FIGS. 16 and 17, the seedling planting body 6 is arranged so that the brush 94 can be surely hit by the brush 94 so that the seedling planting sandwiching tool 31 is not displaced.
The brush 94 may be fixedly provided from the swing link 37 on the rear side. The brush 94 is arranged on the planting locus T in a side view of the machine body, and is brought into contact with the tip of the seedling planting and sandwiching tool 31 to clean it while the seedling planting and sandwiching tool 31 is raised.

FIG. 19 shows a plate-shaped portion 31b at the tip of the seedling planting / holding tool 31, and this plate-shaped portion 31 is shown.
In order to ensure the sandwiching of the seedlings, bar members 31c, which are displaced from each other by a pair of seedling planting sandwiching tools 31, are fixed to the sandwiching surface of b, and the sandwiching surface is made uneven. If the outer surface of the brush 94 protruding between the seedling planting and holding fixtures 31 is made uneven so as to match the uneven shape of the sandwiching face, it is possible to clean every corner of the sandwiching face and the seedling and planting and holding fixture 31.
The sandwiching of the seedlings of the plant becomes stable.

By the way, in order to drive the drive shaft 33 output from the third case portion 32c of the planted transmission case 32 at a non-constant speed, the pair of transmission gears 10 in the third case portion 32c are driven.
The drive shaft 33 can be driven through the non-uniform speed transmission mechanism, for example, by using 0 and 101 as eccentric gears. This allows
The movement locus T ′ drawn by the seedling planting action portion 6a in the field when the machine body travels forward at the set work speed can be set to a desired locus. For example, the seedling planting clamp 31
If the drive shaft 33 is driven at a non-uniform speed so that the speed of the ascending process is faster than the speed of the descending process, it is possible to keep the soil planting holes small and prevent the seedlings from being brought back by the seedling planting / holding tool 31. Can be properly transplanted, and when transplanted in the field where the mulch film is laid, the holes of the mulch film for transplantation can be prevented from becoming unduly large. On the contrary, when the drive shaft 33 is driven at a non-constant speed so that the descending speed of the seedling planting / holding tool 31 is faster than the ascending speed, the motion locus T ′ in the soil becomes longer in the front and rear direction, and Even long seedlings can be transplanted reliably.

Further, as shown in FIG. 20, the supporting member 46
By rotating up and down around the drive shaft 60 of the sprocket 56 on the upper right side, the sprocket 55 on the upper left side can be moved up and down to change the vertical position of the upper transverse feed section 5a. As a result, the height of the upper lateral feed section 5a can be adjusted according to the extension of the operator, the seedling supply operation to the seedling transport section 5 can be facilitated, and the transplantation work efficiency can be improved. In addition, in the ascending feed section 5c, the chain 5
By providing the tension sprocket 103 which gives a tension to 4, the seedling container 26 can be properly conveyed even if the vertical position of the upper lateral feed section 5a is changed.

As shown in FIGS. 21 and 22, a seedling stand 104 may be provided on the left side of the upper lateral feed section 5a. By taking out the seedlings from the seedling placing table 104 and supplying the seedlings to the upper transverse feeding section 5a, both the seedling placing table 104 and the upper transverse feeding section 5a are arranged at a position close to the operator, so that the upper transverse feeding is performed. The operation of supplying seedlings to the portion 5a can be easily performed. The seedling table 104 is supported by the drive shaft 59 of the sprocket 55 on the upper left side through front and rear seedling table support frames 105. By rotating the seedling mounting table 104 above the upper lateral feed section 5a when not in operation, the lateral width of the machine body can be narrowed. Since this seedling placing table 104 is supported by the drive shaft 59 of the sprocket 55 on the upper left side, the upper and lower positions are changed in accordance with the change in the upper and lower positions of the above-described upper lateral feed section 5a, and the seedling placing table 104 is changed. The seedling supply work from 104 to the upper lateral feed section 5a can be easily performed.

Further, as shown in FIG. 23, the seedling table 106
Can be provided on the right side of the upper lateral feed section 5a. As a result, the seedling placing table 10 is provided on the opposite side of the seedling transporting section 5 and the seedling planting body 6 which are offset to the left with respect to the left-right center of the machine body.
Since 6 is arranged, the left-right weight balance of the machine is stable, and seedling transplanting work can be performed stably.
