動的に行い得るものとしたものである。 [Detailed Description of the Invention] The present invention relates to a method and apparatus for planting seedlings grown in continuous paper cylinder pots using a transplanter, which pulls out the seedlings in rows, separates them into individual pot seedlings, and plants them in the main field. be. The continuous paper tube assembly pot body is made by connecting individual paper tubes to form a band shape, and folding the paper tubes into the belt shape in a meandering manner to form a collective pot body. The most typical example is a continuous paper tube assembly pot developed by the present inventor, in which individual pots are connected in a beaded manner at a connecting portion, and the connecting portion has a separation guiding portion with a cut. This continuous paper tube assembly pot body is peeled off in rows and pulled out.
Seedlings are separated into individual pots and planted in the main field.
The transplant machine suitable for this purpose is Special Publication No. 55-3080,
It is described in Utility Model No. 55-39700. These transplanters use a pair of rollers or belts to draw the pots out in a row, and a pair of elastic diagonal rollers or conical rollers with a high circumferential speed positioned in front of the drawer. Seedlings are separated, and after separation, they are dropped through a chute and planted in a pre-drilled trench. The above transplanter is suitable for beet potted seedlings (usually diameter 1.9cm,
height 10-13cm) or corn pot seedlings (usually diameter 3
When used for seedlings in slender pots, such as those with a diameter of 3 to 5 cm and a height of 10 cm, it shows extremely good transplant results, but when used for seedlings in slender pots (usually 3 to 5 cm in diameter and 5 to 7.5 cm in height), If used for transplanting seedlings with large and short pots, the cut of the separation guiding part may not be sufficient, resulting in poor separation, or when separating the seedlings, the seedlings must be held with considerable force from the sides; The rhizosphere soil collapses. Furthermore, as a result of planting through a falling chute, the height of the potted seedling is low, causing it to fall over within the chute, making planting impossible. As a result of many years of research in order to eliminate the above-mentioned drawbacks, the inventor of this invention decided to use forced planting instead of the above-mentioned falling method, and the seedlings were lined up from the time the potted seedlings were held in the planting holder until the completion of planting. It was discovered that by pulling out the pot, stopping it at a predetermined position, and separating the potted seedlings, and transplanting the separated potted seedlings, any seedlings in pots assembled with continuous paper tubes can be reliably transplanted. As a device for pulling out seedlings in rows of continuous paper tube pots from seedlings in continuous paper tube pots, a transplanting rod (holder) that holds the pot seedlings at the tip is used, and the rotation is used to pull out the seedlings. Separation of the pulled-out rows of continuous paper tube pot seedlings into individual paper tube pot seedlings is achieved by using a transplant rod to hold the pot seedlings at the tips of the rows of continuous paper tube pot seedlings. The separation mechanism is based on the rotational force and the operation of a pull-out stop device that comes into contact with the front side of the potted seedling following the tip, and for planting, the transplanting rod further rotates and the clamped potted seedling is separated. The solution was to open it to the ground and configure it like this. Embodiments will be described below using examples of drawings. 1 shows the machine frame of the transplanter, an engine 2 is mounted on the front of the machine frame 1, and wheels 3 are attached below.The wheels 3 receive the rotation of the engine 2 through a chain 4, and the machine moves in the direction of the arrow. Proceed to. A seedling stand 5 is fixed on the machine frame 1, and a potted seedling 6 made of continuous paper tubes is placed thereon. A part of this seedling stand 5 is steeply inclined in the direction opposite to the direction of movement of the machine, and constitutes a pull-out section 5' for continuous paper tube potted seedlings 6-A pulled out from the continuous paper tube assembled potted seedlings 6. do. Therefore,
On the pull-out section 5', the drawn-out continuous paper tube potted seedling 6-A descends with its upper surface facing sideways. A guide plate 51 is provided at the center of the drawer stand 5 or the drawer section 5' to assist in pulling out the seedlings, and a pair of pressing plates 52, 52 which are continuous with the guide plate 51 are provided at the drawer section 5'. ,
The continuous paper cylinder potted seedlings 6-A moving therein are prevented from falling by themselves due to the slope. For this reason, the pressing plates 52, 52 have a portion of the lower side pulled out from the pull-out portion 5'.
Alternatively, the pressing plates 52, 52 may be constructed of leaf springs so that the pressing plates 52, 52 can be pressed inward by slidingly contacting them and a spring 53 is stretched between them to press them inward. A stop plate 8 is opposed to the tips of the pressing plates 52, 52, and the continuous paper cylinder potted seedling 6-
As you can see, the stop plate 8 is in the form of a plate, and a continuous paper cylinder pot-shaped seedling 6- is placed vertically in the center of the stop plate 8.
A groove 9 is provided to allow the connecting portion 7 of A to pass through, and a sliding rod 10 is fixed to the base of the groove 9. A roller 11 is rotatably attached to the other end of the sliding rod 10, a pin 12 is fixed near the roller 11, and the center of the rod is supported by a bearing 13 fixed to the machine frame 1. Further, a spring 14 is provided between the pin 12 and the bearing 13, and is kept under tension at all times.
The roller 11 is rotated by the rotation of a cam 15 that is in sliding contact with the roller 11, and the rotation of the cam 15 is caused by the rotation of the sprocket 17 fixed to the camshaft 16 and the wheel 3.
A chain 20 is stretched between the sprocket 19 fixed to the shaft 18 of the shaft 18, and the chain 20 is rotated. Therefore, the stop plate 8
is interlocked with the wheel 3 and appears and retracts in front of the pressing plates 52, 52 through the pop-out opening 21 opened in the drawer portion 5', but due to the rotation of the cam 15 and the spring 1
Due to the effect of 4, the stop plate 8 is retracted downward, and the stop plate 8 is kept waiting under the drawer part 5' for a certain period of time, and the cam 15 is
When it rotates further, it rapidly moves from the highest point to the lowest point, and the stop plate 8 is rapidly pushed out. On the other hand, the transplanting rod 22 is on the same plane as the feeding surface of the continuous paper cylinder potted seedling 6-A, and its tip rotation locus is in almost sliding contact with the surface of the drawer portion 5'. The transplant rod 22
The base of the rotary disk 23 is radially attached to a pair of rotating disks 23, 23, a shaft 24 of the rotating disk 23 is supported by the machine frame 1, and a sprocket 25 is fixed to the shaft 24. This sprocket 25
is a sprocket 26 fixed to the camshaft 16.
A chain 27 is stretched between the two. Therefore, when the wheel 3 rotates, the cam 15 and the transplanting rod 22 also rotate in conjunction with each other. Further, the transplant rod 22 fixes a T-shaped mounting member 29 whose shaft 28 is fixed between the pair of rotating disks 23 and 23 and extends in a direction perpendicular to the shaft 28. Pin 3 on both sides of the mold
0 and 30, a pair of arm rods 31 and 31 are rotatably fitted loosely therein, and furthermore, clamping rods 32 and 32 are fixed to the tips of the arm rods 31 and 31, and between the arm rods 31 and 31, The clamping rods 32, 3 are tightened by the tensioned spring 33.
Clamping plates 32', 32' fixed to the tips of 2 are spaced apart by a predetermined distance. Further, a pair of opening/closing operation rods 34, 34 are provided downward from the position facing the stop plate 8 along the rotation locus of the arm rods 31, 31, and press the arm rods 31, 31 to adjust the distance between them. The spacing is narrow enough to hold the potted seedling 6-1. Therefore, when the clamping rods 32, 32 rotate and reach the opening/closing rod 34, they clamp the stopped potted seedling 6-1 by the stop plate 8, and when they rotate further and reach the bottom, the engagement is released and the spring 33 is released. Since it opens due to the effect, the potted seedling 6-1 is released into the groove cut by the groove cutter 35. After the release, the following pair of pressure wheels 36 move forward, return the soil to the planting trench, and compact it. Note that 37 is a steering wheel for driving. The transplanting machine of the present invention is constructed as in the above example, but the stop plate 8 is operated by a combination of a sensor and a solenoid, a combination of a sensor and a hydraulic device, or a combination of a sensor and a hydraulic device, or the tip of the transplanting rod instead of the cam 15. It may also be activated by contacting the upper end of the stop plate. Further, the mechanism for moving the stop plate 8 in and out may be replaced with a left and right opening/closing mechanism. Now, to explain this example using the example of the drawing, a pair of left and right stop plates 3
8 and 38 are provided on both ends of the pressing plates 52 and 52, and are fixed to the tips of the support rods 39 and 39. The support rods 39, 39 are connected to the drawer portion 5' of the seedling stand 5.
It is pivotally supported by a pair of bearings 13' fixed to the
Rollers 11', 11' are freely movably attached to the other ends of the support rods 39, 39, and the rollers 11', 11' abut against the cam surfaces of the opposing gums 15', 15', respectively. The cam 15' is fixed perpendicularly to a rotating shaft 41 supported by bearings 40, 40. Further, a bevel gear 42 is fixed to the other end of the rotating shaft 41, and this bevel gear is connected to the shaft 24 of the transplanted rod 22 and a chain (not shown).
It meshes with a bevel gear 44 fixed to a rotating shaft 43 supported by bearings 40', 40'. Further, reference numerals 45, 45 are tension springs that connect the bearing 13' to the support rods 39, 39. Therefore, the left and right stop plates 38, 38 are connected to the cam 1.
Since the shafts 5' and 15' are symmetrical, they open left and right by the rotation of the shaft 43, and rapidly close by the tension of the springs 45, 45. This opening and closing may be replaced by the movement of the stop plate 8. This invention has the above-mentioned configuration, and when the engine 2 is driven during operation, the wheels 3 that move with the engine 2 rotate, and the cam 15 and the transplanted rod 22 also rotate. On the other hand, the front portions of the potted seedlings 6 assembled with continuous paper cylinders on the seedling stand 5 are pulled out in a row in advance, and are held between the pressing plates 52, 52, so that the tip potted seedlings 6-1 are brought to the stop plate 8 protruding position. Let's match. When the rotation of the porting rod 22 begins,
A potted seedling 6-1 with a paper tube at the tip is held between the holding plates 32' and 32'. The operation of each member at this time is shown in Figures 3 and 8.
To explain with a diagram, when the transplanting rod 22 rotates and the clamping plates 32' and 32' at the tip rotate through the gap until the position shown in (a), the continuous paper cylinder potted seedlings 6-A are arranged in a row. The opening is wider than the width of the pot body D ₁ to avoid collisions.
When the transplanting rod 22 further rotates and reaches point (b), the opening/closing operation rod 34 presses the arm rods 31, 31, so that the opening/closing operation rod 34 becomes narrower until the width _D2 can hold the paper tube potted seedling 6-1. Holding plates 32', 32' hold seedlings 6 in pots with paper tubes at the tip.
-1 is clamped. Potted seedling 6 held between holding plates 32', 32'
-1 is pulled out by one pitch by the rotation of the transplanting rod 22 , the roller 11 at the base of the support rod 10 of the stop plate 8 falls from the highest point to the lowest point of the cam 15, and the stop plate 8 is moved to the seedling stand 5. The height of the paper cylinder from the back surface of the drawer portion 5', that is, the tip of the stop plate 8 instantly moves from the position (g) to the position (h). At this time, the stop plate 8 has a paper tube connecting portion 7 at its center.
Since the groove 9 is provided to allow the passage of the continuous paper tube potted seedlings 6-A, the continuous paper tube potted seedlings 6-A will not be cut by the rotation of the transplanting rod 22, and the second paper tube potted seedlings 6 from the top will not be cut. -2 comes into contact with the stop plate 8, the continuous paper cylinder potted seedlings 6-A stop. For this reason, clamping plate 3
2' and 32', the tip paper tube potted seedling 6-1 is forcibly separated from the paper tube connecting portion 7 at the position (c) by rotation of the transplanting rod 22 . Furthermore, transplant rod 2
2 rotates and when the paper tube potted seedling 6-3 held by the holding plates 32', 32' reaches the planting position (d) where the groove is cut by the groove cutter 35, the holding plates 32', 32 'The opening/closing rod 34 with a narrow gap allows the arm rod 3
1 and 31 are released, they are released by the spring and the gap between the clamping plates 32' and 32' is opened.
The paper cylinder potted seedling 6-3 is no longer held in place and is planted in the planting groove. Meanwhile, the stop plate 8 is sequentially moved below the seedling stand 5 by the rotation of the cam 15, and the clamping plates 32', 32' of the next transplanting rod 22 are held at the tip of the paper tube pot body of the continuous paper tube pot seedling 6-A. 6-1 is placed on the lower surface of the drawer part 5' of the seedling stand 5 and allows the rotation of the transplanting rod 22. Therefore, the clamping plates 32', 32' do not become a hindrance to pulling out the potted seedling 6-1 with the tip paper tube. Hereinafter, the above-mentioned operations will be repeated in sequence.
The continuous paper cylinder potted seedlings 6 are pulled out by the rotation of the transplanting rod 22 , separated into individual paper cylinder potted seedlings, and then planted. In addition, pressing plates 52, 52 are provided to draw out the rows of continuous paper tube pot bodies 6-A at all times.
The potted seedlings 6 are assembled in continuous paper tubes in front of the stop plate 8.
Since both sides of the container are clamped with enough pressing force to prevent the container from falling by itself, the container can be pulled out by rotating the transplant rod 22 without cutting the connecting portion 7 between the pressing plates 52 and 52. . Pressing plates 52,5
The length in the pull-out direction where 2 contacts the side of the continuous paper cylinder potted seedling 6-A does not have to be that long, as long as it is long enough to press one to five paper tube potted seedlings with scissors. That's enough. The protruding and retracting movement of the stop plate 8 and the rotational movement of the transplanting rod 22 are caused by the rotation shaft 16 of the cam 15 and the shaft 24 of the rotating ring 25 to which the transplanting rod 22 is fixedly connected by a chain 27. If the rotation ratio of the shafts 9 and 16 is determined in advance according to the number of fixed transplant rods 22 installed, and the number of teeth of the sprockets on which the chains are stretched, then the seedling stand 5 of the stop plate 8 can be adjusted.
The protrusion onto the drawer portion 5' and the separation of the tip paper tube pot body 6-1 by the transplant rod 22 can be performed without any hindrance. As described above, in accordance with the rotation of the transplanting rod 22 , this invention pulls out the rows of continuous paper tube potted seedlings 6-A with its rotational force, and further pulls out the tip paper tube potted seedlings 6-1 with its rotational force. Separate the seedlings into individual paper tube pots, transplant the separated paper tube pot seedlings as they are, and repeat the same operation again when the next transplanting rod 22 comes to the position of the tip paper tube pot seedling 6-1. It was made in a similar manner. Furthermore, the tip of the potted seedling in a row of continuous paper tube pots is always stopped at a fixed position by the stop plate, so even if the pot pitch is long or short, the tip of the paper tube pot will always be on the stop plate. Stopped and fixed. Therefore, errors do not accumulate, and the inability to clamp the transplanting rod due to paper tube deformation and pitch errors, which have traditionally been the bottlenecks for mechanized paper tube transplantation,
Or, it can solve the problem of stopping the operation due to paper tube damage etc. at once, and the seedlings are always restrained in the process from pulling out the seedlings to planting, so there is no free movement of the seedlings and the accuracy of planting is improved. Consistent with accurate movement of the rod, it is possible to obtain extremely good spacing between the stems. If the continuous paper tube assembly pot body used in this invention is provided with a slight separation guiding part and separation line at the connecting part, the leading paper tube pot body will be clamped by the rotation of the transplanting rod, and the tension will be forcibly stopped. Since the connection part with the second paper tube pot body that is completely stopped by the plate is separated, it is possible to use it even with a continuous paper tube assembly in which paper tubes with a low height relative to the diameter are connected. Since the rotational force of the transplanting rod is extremely strong, paper tubes of any shape can be separated very easily by providing a separation line at the connecting part, making mechanical transplantation using a continuous paper tube assembly pot extremely easy. It is designed to be able to perform the process accurately and automatically using a suitable mechanism.
