A rotation drive mechanism 76 is provided further below the seed vat support plate 200.

Hereinafter, the configurations of the rotary table 71, the soot support plate 200, the rotary drive mechanism 76, the safety cover 40, and the protective cover 50 that constitute the soy seed supply unit 70 will be described in more detail.
FIG. 7 is an exploded perspective view illustrating each component of the soy seed supply unit 70.
(1) About the rotary table 71:
In the rotary table 71, cylindrical supply cups 72 having both ends opened are provided through eight through holes 71c opened at equal intervals near the outer periphery of the circular flat portion 71b.

  The supply cup 72 is integrally provided with an attachment rib 72a on the outer peripheral wall slightly below the central portion in the vertical direction, and the attachment rib 72a is in a state where the supply cup 72 penetrates the through hole 71c of the circular flat portion 71b. One side is rotatably supported by the circular flat portion 71b via the rotation support shaft 72b, and a bolt Bo is inserted into a circular arc hole 72c provided on the other side of the mounting rib 72a and is circular with a nut Na. It becomes the structure fixed to the plane part 71b. The supply cup 72 is formed with a notch 72 d that fits into the circular flat portion 71 b on the rear side in the rotation direction of the turntable 71.

  Accordingly, when the supply cup 72 is fixed to the circular plane portion 71b with the bolt Bo and the nut Na in a state where the inner circular space of the supply cup 72 is matched with the through hole 71c of the circular plane portion 71b, the inner circle of the supply cup 72 is fixed. The columnar space becomes the largest through-hole, and the transplanting operation can be performed by placing a large seed culm C in the supply cup 72.

  Then, the supply cup 72 is rotated around the rotation support shaft 72b toward the rear side in the rotation direction of the rotary table 71 so that the cutout portion 72d of the supply cup 72 fits into the circular flat portion 71b. When the seed vat C to be transplanted is small, the size of the internal through hole of the supply cup 72 can be adjusted to be small. Therefore, the small seed C placed in the supply cup 72 is just accommodated in the internal through-hole of the supply cup 72, and is adjusted by moving the supply cup 72 toward the rear side in the rotation direction of the rotary table 71. Therefore, the small seed soot C moves by being pushed on the rear side in the rotation direction of the rotary table 71 of the through hole 71c of the circular flat part 71b, and the small seed soot C moves between the through hole 71c of the circular flat part 71b and the seed soot support plate 200. When the supply port 201 matches, the planting tool 26 is properly supplied into the planting tool 26 at the highest position of the trajectory B, and the small seed culm C spills out without entering the planting tool 26 and transplants. A situation where work cannot be performed is avoided, and appropriate porting work can always be performed.

This is because, for example, if there is no mechanism for adjusting the size of the internal through hole of the supply cup 72, the small seed C is rolled in the internal through hole of the supply cup 72, and the rotary table 71 in the internal through hole is rotated forward. May be located. Then, before the supply cup 72 and the through hole 71c of the circular flat portion 71b completely match, that is, when the front side of the internal through hole of the supply cup 72 comes on the through hole 71c of the circular flat portion 71b, The small seed potato C located on the front side in the rotation direction of the rotary table 71 in the through hole passes through the through hole 71c, and the planting tool 26 has not yet reached the highest position of the locus B. The transplanting operation cannot be performed because it spills outside without entering the planting tool 26. In the above embodiment, such a situation can be avoided, and the supply cup 72 is moved and adjusted toward the rear side in the rotation direction of the rotary table 71 according to the size of the seed soot C. When the through hole 71c of the flat surface portion 71b and the supply port 201 of the seed vat support plate 200 coincide with each other, they are appropriately supplied into the planting tool 26 at the highest position of the trajectory B.
(2) About the seed vat support plate 200:
The seed vat support plate 200 is a disc-shaped plate member having a diameter smaller than the diameter of the rotary table 71 and including the projection area of the lower ends of the eight supply cups arranged in a ring shape, except for the protruding portion 203. In a part of the plate member, a circular supply port 201 larger than the diameter of the lower end opening of the supply cup 72 is provided at the upper opening of the planting tool 26 when the planting unit 26 is located at the top dead center. One is formed at a position corresponding to the upper part of the portion (not shown).

  The seed soot support plate 200 is arranged in parallel to the main surface of the rotary table 71 at a predetermined distance from the lower end edge of the supply cup 72, and the seed soup C supplied to the supply cup 72 is supplied by the seed soup C Except for the mouth 201, the seed vat support plate does not fall from the gap between the lower end edge of the seed cup support plate 200 and the supply cup 72, and the rotating supply cup 72 vibrates during operation. The space | interval of the grade which does not hit 200 is ensured.

  Here, the protruding portion 203 protrudes by a predetermined dimension on the outer peripheral side in the vicinity of the supply port 201, and two through holes 203a for fixing the safety cover 40 with the fastening parts 40a and 40b are provided. The safety cover 40 will be described later.

  Further, the seed vat support plate 200 has a circular through hole 202 through which a bearing member 76g, which will be described later, passes at the center, and a rectangular shape located on the back surface from the edge of the through hole 202 toward the outer periphery. The first plate member 211 and the second plate member 212 are fixed by welding. These first and second plate-like members 211 and 212 are members for attaching the protective cover 50 and also have a function of reinforcing the seed vat support plate 200. The protective cover 50 will be described later.

  Furthermore, the seed vat support plate 200 is formed with a slit-like long hole portion 204 along the radial direction that is large enough to effectively discharge dust accumulated on the upper surface of the seed vat and prevent the seed vat from dropping. .

  On the other hand, on the back surface of the rotary table 71, a rectangular hard rubber scraper 73 for dropping dust from a long hole portion 204 formed in the seed vat support plate 200 is fixedly arranged. The attachment angle of the scraper 73 is less likely to be caught by the long hole portion 204 on the seed vat support plate 200, and in order to allow dust to be discharged not only from the long hole portion 204 but also from the outer peripheral side of the seed vat support plate 200. With reference to the radial direction of the rotary table 71, the rotary table 71 is fixed at an angle α as shown in FIG. Note that the scraper 73 is configured to be longer than the long hole portion 204, and even if the scraper 73 has a shape different from that of the long hole portion 204, the scraper 73 is not easily caught by the long hole portion 204. In addition to the hard rubber, the scraper 73 may have, for example, a brush-like configuration or a plate-like configuration that does not deform, and may be any type as long as it can scrape dust.

  Further, the seed vat support plate 200 is supported by a support column 93 arranged straight from the body of the seed vat transplanter 1 toward the rear of the machine body, and is fixed by welding at the support portion. In addition, the outer peripheral side surface of the bearing member 76g mentioned later is being fixed to the back end 93a of the support | pillar 93 (refer FIG. 9).

Furthermore, a unit fixing angle 260 for fixing a rotation direction conversion unit 76b, which will be described later, is welded and fixed to the rear surface of the seed vat support plate 200.
In addition, according to the said structure, since there is no lid | cover on the bottom face of the supply cup 72 and the support | pillar 93 is directly fixed to the back surface of the seed vat support board 200, the opening position of the lower end of the supply cup 72 (refer FIG. 3) and The distance from the top dead center of the planting tool 26 can be made shorter. Therefore, there is no need to provide a guide member for guiding seed plant C falling from supply port 201 of seed plant support plate 200 to planting tool 26.
(3) Regarding the rotation drive mechanism 76:
Next, the configuration of each part constituting the rotational drive mechanism 76 will be described more specifically.

  FIG. 10 is a schematic plan view for explaining the main part of the rotary drive mechanism 76 of the seed supply unit 70. In order to facilitate understanding of the order of the arrangement of each part, a part of each part is cut out. It is the figure drawn in the state.

  In other words, the rotation drive mechanism 76 rotates with a rotational force transmission member 76c having one end 76a1 rotatably connected to the rotary table drive case 25b and the other end 76a2 rotatably connected to the input side of the rotation direction conversion unit 76b. A first gear 76e1 fixed to an output-side rotation shaft 76d arranged orthogonal to the input-side rotation shaft of the direction conversion unit 76b, and a second gear 76e2 arranged to mesh with the first gear 76e1. ing. The second gear 76e2 rotates smoothly counterclockwise.

  Further, as shown in FIG. 9, a rotation direction conversion unit fixing angle 270 is fixed to the upper surface of the rotation direction conversion unit 76b by a fastening component 270a. Further, the rotation direction conversion unit 76b is fixed to the unit fixing angle 260 fixed to the back surface of the seed vat support plate 200 by the fastening component 270b via the rotation direction conversion unit fixing angle 270.

The bearing member 76g is a bearing member that rotatably supports the rotating shaft 76f of the second gear 76e2, and is fixed to the rear end 93a of the column 93 on the lower end side of the outer peripheral side surface thereof as described above ( (See FIG. 9). On the other hand, the upper end side of the bearing member 76g passes through a through hole 202 provided in the central portion of the seed support plate 200, and the rotary shaft 76f protruding upward from the bearing member 76g is formed in the central portion of the rotary table 71. It is fixed. Thereby, the turntable 71 is rotatably supported by the bearing member 76g via the rotating shaft 76f.
(4) About the safety cover 40:
The safety cover 40 has two through holes 41 a for fixing to the protruding portion 203 formed on one end side, a safety cover mounting portion 41 having a U-shaped cross section, and the other end side of the safety cover mounting portion 41. It is composed of a fixed, elastically deformable rubber or resin safety cover main body 42.

  Thus, the safety cover body 42 completely covers the opening at the upper end of the supply cup 72 when the supply cup 72 moves to the predetermined position G (see FIGS. 3 and 4). You can prevent your fingers from being accidentally inserted.

Further, since the safety cover body 42 is made of an elastically deformable member, even if an operator accidentally pinches a finger between the supply cup 72 and the safety cover body 42, the finger can be pulled out immediately. There is also little damage.
(5) About the protective cover 50:
The protective cover 50 partitions the planting tool 26 and the worker's work position (in this embodiment, the space on the left side of the rotary table 71 with respect to the horizontal direction of the body of the seed vat transplanter 1), It is a cover for covering the space between the lower end of the supply cup 72 protruding to the lower surface side of the turntable 71 and the seed vat support plate 200 and further partitioning between the rotation drive mechanism 76 and the work position of the operator. When the rotary table 71 is viewed from above, the range from the left side of the rotary table 71 to the right side through the steering handle 9 side is protected in a substantially U shape with reference to the horizontal direction of the sow transplanter 1 (FIG. 4). To FIG. 6). Further, the protective cover 50 has a shape in which the lower part extends outward than the upper part.

  The protective cover 50 includes a first mounting member 151 having one end fixedly arranged on the lower surface of the seed vat support plate 200 by a first fixing member 51a, 51b and a second fixing member 52a, 52b, and a second mounting member. The third fixing member 53 is fixed to the third attachment member 153 fixed to the lower side of the outer peripheral surface of the support column 93 by the third fixing member 53. One end of the first mounting member 151 is fixed to the first plate-like member 211 with a fastening part on the lower surface of the seed soot support plate 200, and one end of the second mounting member 152 is on the lower surface of the seed soot support plate 200. The second plate-like member 212 is fixed with fastening parts.

  By providing the protective cover 50 in this manner, the worker is not limited to the work position of the seed vat transplanter 1, but is opposite to the work position (in this embodiment, the left and right sides of the body of the seed vat transplanter 1). Even when the operator is on the right side of the turntable 71 with respect to the direction, it is possible to prevent the operator from coming into contact with the planting tool 26 or having his / her hands caught in the gaps between the rotating parts.

  Moreover, since the 1st plate-shaped member 211 and the 2nd plate-shaped member 212 have the function which attaches the protective cover 50 with the function which reinforces the seed vat support board 200, it can reduce a number of parts.

Next, based on FIG. 11 (a), (b), the structure of the guide guide roller 220 provided in the front part of the body and its vertical operation structure will be described.
The engine 2 provided at the front of the machine body is mounted on an engine base 2a whose base is fixed to the transmission case 3, and a U-shaped shaft rotation support member 221 is bolted to the lower part of the engine base 2a. The guide roller support shafts 223 provided in the left and right directions of the machine body are rotatably supported through the bearing holes 222 provided on the left and right sides of the shaft rotation support member 221 so that the left and right ends protrude. Note that a front weight for adjusting the front-rear balance of the airframe may be provided between the engine base 2a and the shaft rotation support member 221 by tightening with a bolt.

A large number of left and right position adjustment through holes 224 are provided at equal intervals on the left end side of the guide roller support shaft 223, and one fixing through hole 225 is provided on the right end side of the machine body.
The cylindrical boss 227 of the left / right position adjusting member 226 is passed through the left end of the guide roller support shaft 223 and the left / right position adjustment member 226 is passed through the position fixing through hole 227a provided in the cylindrical boss 227 by adjusting the left / right position. The left and right positions are fixed by being inserted into the through holes 224 for adjusting the left and right positions. Further, a fulcrum through-hole 229 and an arcuate through-hole 230 centered on the fulcrum through-hole 229 are provided below the left and right position adjusting member 226. Then, the upper support shaft 232 of the left / right tilt adjusting boss 231 is passed through the fulcrum through hole 229 of the left / right position adjusting member 226, and the lower fixing bolt 233 of the left / right tilt adjusting boss 231 is inserted into the arc-shaped through hole of the left / right position adjusting member 226. 230, the left / right inclination adjustment boss 231 is adjusted to the left / right inclination, and the left / right inclination adjustment boss 231 is fixed to the left / right position adjustment member 226 by a nut 234.

  A plurality of vertical position adjusting through holes 237 are provided at equal intervals on the upper vertical axis 236 of the guide roller rotation support 235 that rotatably supports the guide roller 220. Then, the upper vertical axis 236 is passed through the cylindrical portion 231a of the left / right tilt adjustment boss 231 and the vertical position is adjusted by adjusting the vertical position by passing the fixing pin 238 through the position fixing through hole 231b provided in the cylindrical portion 231a. The vertical position is fixed by being inserted into the through-hole 237 for use.

  On the other hand, the ascending boss 240 is passed through the right end of the machine body of the guide roller support shaft 223, and the fixing pin 241 passes through the position fixing through hole 242 provided in the ascending boss 240 and is inserted into the fixing through hole 225 to be fixed. doing. The arm 243 provided upward on the ascending boss 240 and the upper arm 10 a attached to the right travel extension case 10 are connected by a linkage rod 244. In addition, an interchangeable long hole 245 is provided in a connection portion between the linkage rod 244 and the upper arm 10a.

The right front wheel 4 is rotatably provided in a toe-out state (a state where the right front wheel 4 is slightly facing right when the vehicle is traveling straight).
Therefore, the heel guide roller 220 provided only on the left side of the machine body is adjusted so that it rotates in contact with the side surface of the heel U by adjusting the vertical position, the left and right position, and the right and left inclination so as to straddle the ridge U. The left and right front wheels 4 and the left and right rear wheels 5 travel between the heels to perform transplantation work on the heel U. At this time, the heel guide roller 220 is a simple configuration provided only on the left side of the machine body, but because the right front wheel 4 is toe-out, the machine body appropriately proceeds along the heel U by the heel guide roller 220, Good transplanting work can be performed.

  Further, at the end of the heel U, the hydraulic elevating cylinder 16 is extended so that the left and right traveling chains around the left and right output shafts of the mission case 3 via the horizontal ridge 19, the rear wheel elevating rods 20 and 21, and the left and right upper arms 10a. The case 11 is rotated downward and the left and right rear wheels 5 are moved downward to raise the airframe to turn the airframe. At this time, as the left and right rear wheels 5 move downward, the upper right arm 10a and the linkage rod 244, the elevating boss 240, the guide roller support shaft 223, the left / right position adjusting member 226, the left / right tilt adjusting boss 231 and the guide roller rotating support 235 also raise the eaves guide roller 220. It can be done properly.

  In the vertical movement of the left and right rear wheels 5 during the transplanting operation to the rod U, the rod guide roller 220 does not rise at the interchangeable long hole 245 provided in the connecting portion with the upper arm 10a of the linkage rod 244. Can be performed in a portable manner. That is, when the aircraft is turning, the heel guide roller 220 is raised only when the left and right rear wheels 5 are moved down to the maximum extent beyond the lower movement range of the left and right rear wheels 5 during normal transplantation work.

  In addition, since the linkage mechanism that raises the eaves guide roller 220 is linked to the upper right arm 10a of the right rear wheel 5, a horizontal hydraulic cylinder 22 that is a mechanism for maintaining the airframe horizontally on the right rear wheel 5 side is provided. Since it is not provided (only the left rear wheel 5 is moved up and down by the horizontal hydraulic cylinder 22 which is a mechanism for maintaining the aircraft horizontally to the left and right), the guide roller 220 is raised at an appropriate timing when the aircraft is turning. The turning operation of the airframe is easy and appropriate.

Next, the operation | movement centering on the seed vat supply part 70 and the planting tool 26 of the seed vat transplanter 1 of this Embodiment is demonstrated.
First, with the sub-mounting frame 33 of the seed vat mounting table 30 pulled out to the rear of the main mounting frame 32, three containers A containing the seed vat C are placed in the main mounting frame 32 side by side in the left-right direction of the machine body. Then, one container A containing the seed soot C is placed on the sub placement frame 33.

  Next, the engine 2 is started, and the seed vat transplanter 1 slowly advances so as to straddle the rod U as the planting operation starts. On the other hand, the rotation of the engine 2 is transmitted to the rotational force transmission member 76c, and the rotary table 71 smoothly rotates counterclockwise via the first gear 76e1 and the second gear 76e2.

  The operator is located in the work space on the left side of the seed vat transplanter 1, and the safety cover 40 is installed in the supply cup 72 that rotates as the rotary table 71 rotates while keeping pace with the forward movement of the machine body. From the container A placed on the sub-mounting frame 33 with respect to the supply cup 72 that has already passed through the predetermined position G (see FIG. 3) and has already been emptied by supplying the seed pod C to the planting tool 26 side. Take out seeds C and replenish them one by one. By repeating this, the seed cup C is sequentially supplied to the eight supply cups 72. At this time, the operator can take out the soot C from the container A placed on the sub-mounting frame 33 and can easily put it into each supply cup 72 of the side soot feeding unit 70, with good workability and The transplanting operation can be performed efficiently. When the seed C of the container A placed on the sub placement frame 33 runs out, the container A containing the seed soup C on the main placement frame 32 is replaced and the operation is continued.

  In this way, it is possible to prevent the operator from mistakenly inserting a finger or the like into the supply cup 72 that passes through the predetermined position G during the operation of replenishing the soy seed C. If the safety cover 40 is not installed, if a finger or the like is accidentally inserted into the supply cup 72, the opening edge on the lower surface side of the supply cup 72 and the inner peripheral edge of the supply port 201 will be described. There is a possibility of fingers being caught between them.

  Furthermore, since the safety cover main body 42 is made of an elastically deformable member, even if an operator accidentally pinches a finger between the supply cup 72 and the safety cover main body 42, the safety cover main body 42 It can be said that the safety is high because there is little damage.

  In addition, on the upper surface of the seed vat support plate 200, the seed vat C rolls with the rotation of the supply cup 72, so that various kinds of dust are easily collected. Such dust is collected by the rotation of the scraper 73 attached to the back surface of the turntable 71, and when the scraper 73 passes through the slit-like long hole portion 204 provided in the seed vat support plate 200, its length is increased. While being discharged downward from the hole portion 204, due to the inclination angle α of the scraper 73, it is also always discharged from the outer peripheral side of the seed vat support plate 200.

  On the other hand, the opening at the lower end of the supply cup 72 is closed by the seed vat support plate 200 except when the supply cup 72 comes to a predetermined position G (see FIG. 3) by the rotation of the turntable 71.

  That is, as shown in FIG. 4, when the supply cup 72 passing through the predetermined position G moves a certain distance after starting to pass immediately above the supply port 201 (the center of the opening at the lower end of the supply cup 72 is supplied). When the seed vat C that has been rolling along with the rotation of the supply cup 72 has moved to the location of the supply port 201, the surface of the seed vat support plate 200 until then has moved to the location of the supply port 201). Since the support by the seed vat support plate 200 is lost, it starts to fall downward. Then, the sow seed C is supplied to the planting tool 26 that has just arrived at the top dead center position (the position shown in FIG. 1), and then the planting tool 26 moves downward along the locus B, When it comes to the lowest end, planting of the seed pod C is performed in the field.

  At this time, when transplanting a large seed soy C, the operator circularizes the supply cup 72 with the bolt Bo and nut Na in a state where the inner circular space of the supply cup 72 is matched with the through hole 71c of the circular flat portion 71b. It fixes to the plane part 71b. Then, the inner cylindrical space of the supply cup 72 becomes the largest through hole, and the large seed potato C put into the supply cup 72 by the operator coincides with the center of the supply port 201 at the center of the lower end of the supply cup 72. Sometimes, it is properly supplied from the supply port 201 to the planting tool 26 just at the top dead center position, and a good transplanting operation can be performed.

  When transplanting a small seed soy C, the operator can move the supply cup 72 around the rotation support shaft 72b in the rotational direction rearward side so that the notch 72d of the supply cup 72 fits into the circular flat portion 71b. , And the size of the internal through hole of the supply cup 72 can be adjusted to be small according to the size of the small seed C to be transplanted. Therefore, the small seed C placed in the supply cup 72 is just accommodated in the internal through-hole of the supply cup 72, and is adjusted by moving the supply cup 72 toward the rear side in the rotation direction of the rotary table 71. Therefore, the small seed soot C moves by being pushed on the rear side in the rotation direction of the rotary table 71 of the through hole 71c of the circular flat part 71b, and the small seed soot C moves between the through hole 71c of the circular flat part 71b and the seed soot support plate 200. When the supply port 201 matches, it will be properly supplied into the planting tool 26 that has just reached the top dead center position, and the small seed bud C will spill outside without entering the planting tool 26. Therefore, it is possible to avoid a situation where the transplanting work cannot be performed and to always carry out an appropriate transplanting work.

  That is, as shown in FIG. 1, the planting tool 26 is configured to be divided into two in the front-rear direction to open and close the lower part. As a result, in a state in which the single soot C inherited from the supply cup 72 of the rotary table 71 is accommodated and held, it descends from the top dead center position as shown by the trajectory B (see FIG. 1), and the lower part is lowered at the sowing seed planting position. A planting hole is formed in the pod U by opening it back and forth, and seed pod C is supplied to the planting hole and planted. Thereafter, the planting tool 26 returns to the top dead center position again. The operation indicated by the trajectory B of the planting tool 26 (see FIG. 1) is synchronized with the rotation operation of the rotary table 71, and when the supply cup 72 reaches the predetermined position G (see FIG. 3), the planting tool 26 is operated. Is configured to return to the top dead center position.

  In addition, since the protective cover 50 is arranged so as to partition each drive unit below the rotary table 71 from the work position of the worker, the worker is prevented from coming into contact with the drive unit. I can do it.

  A farm scene sensing plate 36 is provided in front of the planting tool 26. The field scene sensing plate 36 is provided so as to be rotatable around a pivot point 36a in the left-right direction, and a predetermined planting depth is set by the seed planting device 60 in accordance with the rotation of the field scene sensing plate 36 by grounding. The rear wheel 5 is raised and lowered so that

  The pressure-reducing wheel 8 is provided at a rear position of the seed sowing planting position, and is supported by a pressure-reducing wheel support frame 38 that can swing up and down around the horizontal axis 37. In addition, the pressure wheel 8 rolls on the heel surface as the seed culm transplanter 1 advances, collapses the soil around the transplant hole after the seed culm is planted, and refills the hole. At 26, the bank that has risen before and after the transplantation hole, particularly at the rear, is crushed flatly.

Thereby, the soil around the transplanted seed potato can be flattened, and the growth of potato can be improved.
As described above, according to the seed vat transplanting machine of the present embodiment, instead of the conventional configuration in which an opening / closing lid is provided for each supply cup 72, a configuration including the seed vat support plate 200 is adopted, thereby simplifying the configuration. We were able to provide a seed vat transplanter that could reduce the number of parts.

Further, by providing the safety cover 40 and the protective cover 50, the worker can work more safely.
In the above-described embodiment, a case has been described in which a pendulum-type left / right tilt sensor 23 is provided, and the horizontal hydraulic cylinder 22 is operated by the detection of the left / right tilt sensor 23 to maintain the body horizontally. For example, a manual horizontal lever for manually controlling the horizontal hydraulic cylinder 22 without the left / right tilt sensor 23 is provided so that the worker replenishes the supply cup 72 with seeds. It may be arranged on the position (work space) side and above the rear wheel 5.

  In this case, the horizontal hydraulic cylinder 22 is operated by operating the left and right tilt valves provided in the hydraulic pressure switching valve unit 17 with a horizontal lever. That is, the operator operates the left and right tilt valves by moving the horizontal lever in the left-right direction.

  In addition, in the above embodiment, the case of transplanting seed potatoes such as potatoes has been described as an example of the transplant object of the present invention. However, the present invention is not limited to this. The present invention can also be applied to and exhibits the same effects as described above.

  Moreover, in the said embodiment, although the case where a seed pod was transplanted was demonstrated, not only this but a vegetable seedling can also be planted by comprising the supply cup 72 in the standard cup size of a vegetable seedling, for example. Become.

(Embodiment 2)
A second embodiment of the rotary table 71 capable of performing an appropriate transplanting operation regardless of the size of the seed potato C will be described.

Cylindrical supply cups 72 that are open at both ends are respectively provided in eight through holes 71c that are opened at equal intervals near the outer periphery of the circular flat portion 71b.
Each supply cup 72 has a configuration in which a potato presser body 300 is provided to press seed potatoes C contained therein toward the rear side in the rotational direction of the rotary table 71.

  The potato presser body 300 pivotally supports a base portion 300 a on a circular flat portion 71 b near the supply cup 72 by a rotation support shaft 301. And the front-end | tip part is arrange | positioned in the supply cup 72, and the holding | suppressing part 302 is formed in the front-end | tip part. The pressing portion 302 is configured by a plate-like body that is inclined toward the rear side in the rotation direction of the turntable 71. As shown in FIG. The seed potato C is prevented from moving carelessly, and the seed potato C is positioned in a stable manner.

  The holding portion 302 is integrally formed with the base portion 300a via the connecting portion 303, and the connecting portion 303 passes through a notch groove 72e formed in the supply cup 72, and the holding portion 302 rotates together with the base portion 300a. It has become.

  The base portion 300a is integrally formed with a driven cam 304 that protrudes to the opposite side of the pressing portion 302 with respect to the rotation support shaft 301, and is fixed to the rotation center side of the circular flat portion 71b that the driven cam 304 faces. A cam 305 is provided to be fixed to the seed vat support plate 200. The outer peripheral shape with which the driven cam 304 of the fixed cam 305 contacts is formed with a recessed portion 305a having a recessed shape at a portion facing the supply port 201 of the seed vat support plate 200 in a plan view, and the other portion has a circular shape 305b. It is.

  Further, a first spring locking pin 306 is provided on the upper surface of the base 300a on the driven cam 304 side, and one end side of a winding spring 307 that allows the main body portion to pass through and support the rotation support shaft 301 is connected to the first spring. The driven cam 304 integral with the base portion 300a is biased by the winding spring 307 by engaging with the stop pin 306 and engaging the other end with the second spring locking pin 308 fixed to the circular flat portion 71b. The structure is always in contact with the fixed cam 305.

  Therefore, while the driven cam 304 is in contact with the circular shape 305b of the fixed cam 305, the pressing portion 302 of the potato pressing body 300 is in a retracted state in contact with the inner wall surface of the supply cup 72. The soy seed C can be easily put in the supply cup 72 and the workability is good.

  On the other hand, while the driven cam 304 is in contact with the concave portion 305 a of the fixed cam 305, the pressing portion 302 of the potato pressing body 300 is separated from the inner wall surface of the supply cup 72 by the urging force of the winding spring 307. The seeds C placed in the supply cup 72 are pressed against the wall surface of the supply cup 72 on the rear side in the rotation direction of the rotary table 71.

  Therefore, as the rotary table 71 rotates, the seed C placed in the supply cup 72 from immediately before the supply cup 72 comes over the supply port 201 until immediately after the supply cup 72 matches the supply port 201 is It is in a state of being pressed against the wall surface of the supply cup 72 on the rear side in the rotation direction of the rotary table 71 by the pressing portion 302 of the potato presser body 300, and regardless of the size of the seed potato C, the supply cup 72 and the seed potato support plate 200 When the supply port 201 matches, the planting tool 26 is properly supplied into the planting tool 26 at the highest position of the trajectory B, so that the seed culm C spills out without entering the planting tool 26 and transplanting work. The situation where it becomes impossible to do so is avoided, and appropriate porting work can always be performed. In addition, the holding portion 302 that is inclined toward the rear side in the rotation direction of the rotary table 71 holds the seed candy C downward while the seed candy C is pressed, and the supply cup 72 matches the supply port 201. When the seed potato C is dropped and supplied, the seed moth C is biased downward, so that the seed moth C is properly and immediately supplied into the lower planting tool 26 by this urging force. Appropriate transplantation work can be performed.

(Embodiment 3)
A third embodiment of the rotary table 71 capable of performing an appropriate transplanting operation regardless of the size of the seed potato C will be described.

Cylindrical supply cups 72 that are open at both ends are respectively provided in eight through holes 71c that are opened at equal intervals near the outer periphery of the circular flat portion 71b.
Each supply cup 72 has a configuration in which a potato position restricting body 310 is provided for positioning the seed soot C put in the supply cup 72 on the rear side in the rotation direction of the rotary table 71.

  The potato position restricting body 310 has an upper end base portion 311 fixed to the upper end portion of the inner wall of the supply cup 72 with a fixing tool 312 such as a screw, and a lower portion that can freely move, and is formed of a flat rubber plate. The length L from the position where the potato position restricting body 310 is fixed to the supply cup 72 to the lower end is longer than the height H from the position where the potato position restricting body 310 is fixed to the supply cup 72 to the lower end of the supply cup 72. However, the width W of the lower portion of the potato position regulating body 310 is configured to be smaller than the diameter D of the supply port 201 of the seed vat support plate 200.

  Therefore, at the position where the supply cup 72 is aligned with the supply port 201, the lower part of the potato position regulating body 310 passes through the supply port 201 and hangs straight downward, and the seed C placed in the supply cup 72 Falls from the supply port 201 and is supplied into the lower planting tool 26 so that an appropriate transplanting operation can be performed.

  On the other hand, the lower part of the potato position regulating body 310 in a state of drooping straight as the supply cup 72 passes over the supply port 201 with the rotation of the rotary table 71 after the seed potato C has dropped from the supply port 201 When the supply cup 72 passes over the supply port 201 when it is lifted at the edge of the port 201, the lower portion of the potato position regulating body 310 is in an inclined state where the lower portion is positioned on the rear side in the rotation direction of the rotary table 71. 71 is in sliding contact with the upper surface of 71. When the worker puts the seed potato C into the supply cup 72 when the potato position restricting body 310 is in the inclined state, the seed potato C is moved backward in the rotation direction of the rotary table 71 in the supply cup 72 by the potato position restricting body 310 in the inclined state. The supply cup 72 is in contact with the wall surface so as to be stably positioned.

  Then, the seed potato C put in the supply cup 72 is positioned on the rear side in the rotation direction of the rotary table 71 in the supply cup 72 by the potato position restricting body 310 regardless of the size of the seed potato C. When the supply port 201 of the seed vat support plate 200 matches, the seed vat C will be appropriately supplied into the planting tool 26 at the highest position of the locus B, and the seed vat C will spill outside without entering the planting tool 26. Therefore, it is possible to avoid a situation in which the transplanting work cannot be performed and to always carry out an appropriate porting work.

  However, each supply cup 72 rotates on the seed soot support plate 200 in a state where the bottom end of the potato position restricting body 310 is in sliding contact with the upper surface of the turntable 71, so that the bottom end of the potato position restricting body 310 is on the seed soot support plate 200. It can also serve as a scraper that cleans up dirt and mud, and can carry out appropriate transplantation for many years.

(Embodiment 4)
A fourth embodiment of the rotary table 71 capable of performing an appropriate transplanting operation regardless of the size of the seed potato C will be described.

Cylindrical supply cups 72 that are open at both ends are respectively provided in eight through holes 71c that are opened at equal intervals near the outer periphery of the circular flat portion 71b.
Similarly to the third embodiment, each supply cup 72 is provided with a potato position restricting body 320 that positions the seed soot C contained in the supply cup 72 on the rear side in the rotation direction of the turntable 71.

  The potato position regulating body 320 of this embodiment has a configuration in which a plurality of vertical rods 322 are provided in a comb-teeth shape on the upper horizontal shaft 321, and the upper horizontal shaft 321 is rotatably supported on the upper end of the inner wall of the supply cup 72. The lower part is configured to swing freely. The length L from the position where the upper horizontal shaft 321 of the potato position regulating body 320 is pivotally supported to the supply cup 72 to the lower end is from the position where the potato position regulating body 320 is pivotally supported to the supply cup 72 to the lower end of the supply cup 72. The width W of the lower portion of the potato position restricting body 310 is configured to be smaller than the diameter D of the supply port 201 of the seed vat support plate 200.

  Therefore, at the position where the supply cup 72 is aligned with the supply port 201, the lower part of the potato position regulating body 320 passes through the supply port 201 and hangs straight downward, and the seed C placed in the supply cup 72 Falls from the supply port 201 and is supplied into the lower planting tool 26 so that an appropriate transplanting operation can be performed.

  On the other hand, as the rotary table 71 rotates after the seed soot C has dropped from the supply port 201, the lower part of the potato position regulating body 320 in a state of drooping straight as the supply cup 72 passes over the supply port 201 When the supply cup 72 passes over the supply port 201 when it is lifted at the edge of the port 201, the lower portion of the potato position restricting body 320 is in an inclined state in which the lower part is positioned on the rear side in the rotation direction of the rotary table 71. 71 is in sliding contact with the upper surface of 71. If the worker puts the seed potato C into the supply cup 72 when the potato position restricting body 320 is in the inclined state, the seed potato C is moved backward in the rotation direction of the rotary table 71 in the supply cup 72 by the inclined potato position restricting body 320. The supply cup 72 is in contact with the wall surface so as to be stably positioned.

  Then, the seed potato C placed in the supply cup 72 is positioned on the rear side in the rotation direction of the rotary table 71 in the supply cup 72 by the potato position restrictor 320 regardless of the size of the seed potato C. When the supply port 201 of the seed vat support plate 200 matches, the seed vat C will be appropriately supplied into the planting tool 26 at the highest position of the locus B, and the seed vat C will spill outside without entering the planting tool 26. Therefore, it is possible to avoid a situation in which the transplanting work cannot be performed and to always carry out an appropriate porting work.

  However, each supply cup 72 rotates on the seed soot support plate 200 in a state where the lower end of the potato position restricting body 320 is in sliding contact with the upper surface of the turntable 71, so that the lower end of the potato position restricting body 320 is on the seed soot support plate 200. It can also serve as a scraper that cleans up dirt and mud, and can carry out appropriate transplantation for many years.
