DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting apparatus used for a walking type or riding type transplanter for planting seedlings in a ridge while advancing in the longitudinal direction of the ridge.

[0002]

2. Description of the Related Art As this type of transplanter, for example, one described in Japanese Patent Application Laid-Open No. 10-4729 is known. This transplanter has a seedling supply device for supplying pot seedlings, a seedling removal device for taking out the pot seedlings of the seedling supply device, and a planting device for receiving the seedlings from the removal device and planting the seedlings in a field ridge. The seedlings are planted on the ridges while moving in the longitudinal direction of the ridges. The planting device includes a planting body supported by a lifting mechanism so as to be able to move up and down, and a lower part of the planting body is configured to be openable and closable back and forth from a pair of front and rear components. A downwardly tapering beak-shaped opening device is provided.

[0003] Then, by lowering the planting body with the opening device closed, piercing the opening device into the ridge and opening it, a planting hole is formed in the ridge, and the seedling held in the planting body in the planting hole is formed. It is configured to be dropped and planted. Also,
The ridges may be covered with a multi-film, and when seedlings are planted on the ridge covered with the multi-film with the above-described planting device, the transplanter has a perforated body that forms a hole for inserting an opening device. Be provided. This perforated body is formed of, for example, a cylindrical body heated by a gas burner, an electric heating coil, or the like, and is supported so as to be able to move up and down, and descends to contact the multi-film, thereby forming a substantially circular hole in the multi-film. I do.

[0004]

By the way, when planting vegetable seedlings such as cabbage and Chinese cabbage, only the floor soil of the pot seedlings is immersed in the planting hole formed by the opening device.
By the left and right covering pressure suppressors, the seedlings of the seedlings are gathered from both the left and right sides and planted so as to suppress the strains, and the upper end opening of the planting hole and the insertion hole formed in the multi-film by the perforated body are: Although it is roughly the corresponding size,
When planting tobacco seedlings, in order to protect the leaves of the seedlings from frost damage, openers are formed so that the leaves of the seedlings are immersed in the planting holes so that deep and large planting holes are formed. Is done.

[0005] As shown in FIG.
When the seedling S grows, the upper end opening of the planting hole H is larger than the insertion hole A formed in the multi-film M, and the seedling S is immersed in the planting hole H. There is a problem that the leaf portion S1 enters between the ridge R surface (upper surface) and the multi-film M and affects the growth and the like of the seedling S. Further, in summer or the like, the multi-film M becomes hot, and when the hot multi-film M comes into contact with the leaf portion S1, the growth of the seedling S is affected.

For this reason, in the tobacco cultivation, after the seedlings S are planted, the leaves S1 are reworked so as to come out from the multi-film M, which is a manual operation.
Since the number of seedlings S is large, this is a rather difficult operation. In addition, it is considered that a cut is made before and after the insertion hole A by providing a cutter before and after the opening device. However, even in this case, the above problem has not been solved. In addition, the insertion hole A formed in the multi-film M may be formed as a large insertion hole A for the tobacco seedlings S. However, a separate punching device must be made for transplanting the tobacco seedlings S. Is larger, the energy required to heat the perforated body is correspondingly greater, and there are many problems, and it is difficult to increase the insertion hole A formed in the multi-film M.

Further, in the transplanter for tobacco seedlings S, no cover soil pressure suppressor is provided, and after the planting, in order to prevent the drying of the floor portion S2 of the seedlings S, the upper portion of the planting hole H is fixed with a rod B or the like. The soil is covered by covering the floor S2, and the work of breaking the soil is also a manual operation, and the number of seedlings S is large.
Then, an object of the present invention is to provide a planting device which can solve the above-mentioned problems.

[0008]

The technical means taken by the present invention to achieve the above object is to provide an openable and closable opening device at the lower part of a planting body which can be moved up and down, and to close the opening device. The planting body is lowered by piercing and opening the opening device in the ridge, thereby forming a planting hole in the ridge and planting a seedling held in the planting body in the planting hole. A cutter is provided on each side of the container before and after and on both left and right sides to cut the multi-film covering the surface of the ridge.

In the above construction, the opening device is configured to be openable and closable back and forth from a pair of front and rear members, and a cutter is provided on a front side of the front member and a rear side of the rear member. Alternatively, it is preferable to provide cutters on both left and right sides of the rear structure. Further, in the planting device for planting a seedling while traveling in the front-rear direction, it is preferable that a cutter provided on a side portion of the opening device is provided on a component on the front side in the traveling direction.

Further, rear wheel support shafts 9 are provided from both left and right sides of the transmission case 4 so as to protrude in the left-right direction.
The transmission case 10 is mounted in an inclined manner such that the transmission case 10 shifts downward as it goes rearward, and a rear wheel 11 is supported at the tip end of the transmission case 10. A running power transmission shaft 12 is inserted through the shaft center of the rear wheel support shaft 9, and the power of the engine is transmitted from the transmission shaft 12 to the rear wheel 11 via the inside of a transmission case 10. .

The transmission case 10 is vertically swingable about the rear wheel support shaft 9 by the operation of the lifting cylinder 13. The movement of the lifting cylinder 13 is controlled by an interlocking link 14.
The front wheel arm 7 also swings up and down around the front wheel support shaft 6 so that the heights of the front and rear wheels 8 and 11 and the vehicle body 3 can be adjusted. The left and right transmission cases 10 swing in opposite directions by the operation of the rolling cylinder 15, and the swing is caused by swinging the left and right front wheel arms 7 in opposite directions via the interlocking link 14. The vehicle body 3 can be rolled in the left-right direction, and horizontal control in the left-right direction can be performed.

Further, the distance between the left and right front wheel arms 7 and the distance between the left and right transmission cases 10 can be adjusted so that the wheel distance can be adjusted. In the transplanting machine according to this embodiment, the right and left front wheels 8 and 11 are moved in the left-right direction with respect to the vehicle body 3 so that the wheel span can be adjusted. As shown in FIG. 13, a fixed cylindrical shaft 70 supported and fixed to the transmission case 4 side, and a movable cylindrical shaft which is removably mounted on the fixed cylindrical shaft 70 and is rotatably fitted around a left-right axis. And the rear wheel support shaft 9
Is stretchable in the left-right direction. In addition, the movable cylinder shaft 7
The front side of the transmission case 10 is fixed to the left and right outer ends of the transmission case 1 so that the transmission case 10 can swing up and down and can move left and right.

The movable cylinder shaft 71 is supported by a support frame 72 fixed to the transmission case 4 via a bearing 73 so as to be movable left and right and rotatable about a horizontal axis. The traveling power transmission shaft 12 disposed at the shaft center of the right rear wheel support shaft 9 includes a drive side shaft portion 74 and a driven side shaft portion 75. The driving side shaft portion 74 is
The power is transmitted from the engine via a transmission device in the transmission case 4, which is rotatably supported on the fixed cylinder shaft 70 side around the axis.

The driven side shaft portion 75 is spline-fitted to the driving side shaft portion 74 so as to be rotatable integrally and movably to the left and right, and is rotatable about the axis in the left and right direction to the movable cylinder shaft 71. It is supported and transmits power from the drive-side shaft 75 to a power transmission mechanism in the transmission case 10. Further, a wire 76 is provided between the fixed cylindrical shaft 70 and the movable cylindrical shaft 71 to restrict the movement of the movable cylindrical shaft 71 to the outer end in the left-right direction. One end of the wire 76 is locked by a locking member 78 provided on a bracket 77 fixed to the fixed cylinder shaft 70,

A machine frame 16 extending rearward is fixed to an upper portion of a rear portion of the transmission case 4, and main handles 17 are attached to the rear end of the machine frame 16. A handle 82 is provided. In the cultivation of tobacco, as shown in FIG.
Since the entire seedling S is immersed, the ridge becomes a large ridge (having a large height and width) R. However, when a transplanting machine is formed on the large ridge R so as to correspond to a normal ridge, the ridge becomes large. Since the height of R is high, the vehicle body must be raised accordingly, so the transmission case supporting the rear wheels comes up. However, if the transmission case is set up too much, horizontal control in the left and right direction becomes difficult. Therefore, in a transplanter for tobacco cultivation, a long transmission case 10 is used to correspond to the large ridge R.

In a walking type transplanter, for example, at the time of turning with a pillow, the steering wheel is normally pushed down by pushing down a steering wheel around a rear wheel to raise a front wheel, and one of right and left rear wheels is raised. This is done by turning off the power transmission to the front wheel.At this time, the transmission case is set up so that the front wheels can be easily raised. And it becomes difficult to push down the handle. Therefore, in the transplanting machine according to this embodiment, the main handle 17 is provided with a pair of left and right auxiliary handles 82 located below the grip portion of the handle 17.
It is considered that the auxiliary handle 82 is used so that the rear part of the transplanter can be easily pushed down at the time of turning on a pillow or the like.

Therefore, the operation lever 83 for operating the steering clutch for turning on / off the power transmission to the rear wheel 11 is attached to the auxiliary handle 82. In addition, during normal work or when moving, the auxiliary handle 82 is in a low position and the waist is bent. Therefore, by using the main handle 17, it is necessary to perform work or the like while standing straight. Can be. A planting frame 18 is attached to the lower part of the rear part of the mission case 4 so as to extend rearward and swing vertically. The transplanting device 2 is provided on the machine frame 16 and the planting frame 18.

As shown in FIG. 1 to FIG.
2 is a planted body 31 whose lower side can be opened and closed back and forth,
It has an elevating device 32 for vertically moving the plant 31 and an opening / closing device 33 for opening and closing the lower side of the plant 31, and the plant 31 is in a raised position in which the lower part of the plant 31 is closed. The transplanted seedlings are thrown in from above and stored therein, and the planted body 31 is lowered to pierce and open the lower part of the planted body 31 in the ridge R, as shown in FIG. The seedlings S in the planted body 31 are planted in the ridges R by forming the seedlings H and dropping and releasing the seedlings S held in the planted body 31 into the planting holes H.

The plant 31 has an upper support cylinder 34,
A lower opening device 41 that is openable and closable back and forth, a pair of front and rear mounting bodies 40 that openably and closably support the opening device 41 on the support cylinder 34 via a pair of front and rear pivot portions 35, and the support cylinder 34 from above. It is composed of a tubular seedling guide 36 fitted inside. The seedling guide 36 is made of plastic and can be elastically deformed, guides the seedling S introduced from above downward, and supports the leaf portion S1 of the seedling S on its inner peripheral surface when the opening device 41 is closed. Thus, the seedling S is maintained in a state of standing substantially straight.

That is, the seedlings S are thrown from above into the planting body 31 with the floor soil S2 as the lower side, the thrown seedlings S pass through the seedling guide 36, and the bottom side of the floor soil S2 is opened by the opening device 41.
Is stopped, the seedling S is held in the planted body 31, and the leaf S2 is supported by the seedling guide 36, so that the seedling S is held in a substantially straight standing state.
By providing the seedling guide 36, when the opening device 41 is pierced into the ridge R and opened, the seedling S falls downward from a state of standing straight, so that when the seedling S is released into the planting hole H, The posture of the seedling S is improved, and the posture at the time of planting the seedling S is not bad and must be corrected.

As shown in FIGS. 4 and 8 to 10, the seedling guide 36 has a rectangular shape on the upper side and a substantially cylindrical shape on the lower side. 4 places (may be 2 places, 3 places or 5 places or more),
Vertical slits 37 are formed, and each slit 37 is formed so as to be open at the lower end and to become gradually narrower as it goes upward, and the lower side (the holding portion of the seedling) of the seedling guide 36 is formed in the radial direction. It is allowed to expand and contract (laterally expand and contract). Then, by fitting a regulating member 85 composed of an O-ring or the like to the lower outside of the seedling guide 36,
The tip diameter (lower end diameter) of the seedling guide 36 can be changed.

Therefore, even if the leaves S1 are small seedlings, the seedlings S can be reliably held in the planted body 31 by reducing the diameter of the tip of the seedling guide 36. If the tip diameter is small, the seedling S having a large leaf portion S2 may be caught by the seedling guide 36 and may not fall. it can. In order to change the tip diameter of the seedling guide 36, for example, the O-ring 85 having a different diameter is prepared and replaced.
This is performed by changing the position of the external fitting 5 in the vertical direction.

On the outer peripheral surface side of the lower part of the seedling guide 36,
Protrusions 84 for hooking the O-ring 85 are formed at intervals in the vertical direction. By forming the slit 37, the contact area with the floor soil portion S2 is reduced, and the soiling on the inner surface of the seedling guide 36 can be reduced. Also,
In order to further reduce the soiling, cutouts 38 opened at the lower end are formed at the lower left and right sides of the seedling guide 36. The opening device 41 is composed of front and rear components 41A and 41B, and in a closed state, is formed in an upwardly open cup shape formed in a downwardly tapered beak shape. Can hold and hold the seedling S.

At the front and rear of the support cylinder 34, a left-right pivot 35 formed of a cylindrical body is fixed by welding or the like, and a shaft 39 is inserted through the pivot 35. A front mounting body 40A is mounted on the front shaft 39, and a rear mounting body 40B is mounted on the rear shaft 39. The front side of the opening device 41 is provided at the lower end of the front mounting body 40A. Construct 41 of
A is attached, and the rear component 41B of the opening device 41 is attached to the lower end of the rear attachment 40B. Thereby, the components 41A and 41B before and after the opening device 41 are supported by the support cylinder 34 so as to be able to swing back and forth around the left-right axis, and from the closed state of the opening device 41 shown in FIG.
The component 41A on the front side of the opening device 41 is forward (in the direction of arrow C).
As the component 41B on the rear side of the opening device 41 swings rearward (in the direction indicated by the arrow D), the opening device 41 opens back and forth.

The mounting body 40 is formed in a U-shape in plan view, and the pair of front and rear mounting bodies 40 are urged by a spring 42 so that their left and right side walls approach each other. Therefore, the opening device 4 is formed by the spring 42.
1 (the front and rear components 41A and 41B) are urged to close. Also, on the left and right side walls of one of the mounting bodies 40,
An interlocking pin 43 protrudes, and a long hole 44 with which the pin 43 engages is formed on the side wall of the other mounting body 40. When one of the attachments 40 rotates about the axis 39 of the pivot 35, the other attachment 40 also pivots about the axis 39 of the pivot 35 by the engagement of the interlocking pin 43 and the elongated hole 44.
