The reason why the inclination of 30 degrees is provided is to allow the left and right lower end protrusions 252a and 252b of the partition plate 250 to easily enter the left and right lower cut grooves 720sa and 720sb and to come out smoothly.

  Further, the partition plate 250 is provided with two cut portions 254 formed from a position slightly lower than the center to the lower end. The notch width of the notch 254 is formed corresponding to the range of movement due to the deformation of the left lower end protrusion 252a and the right lower end protrusion 252b when the partition plate 250 is attached to the supply cup 72. This ensures that the left and right lower end protrusions 252a and 252b of the partition plate 250 can securely enter and exit the left and right lower cut grooves 720sa and 720sb, and the lower left end when the partition plate 250 is attached to and detached from the supply cup 72. This is for improving the durability against the elastic deformation of the protrusion 252a and the right lower end protrusion 252b.

  Further, in the vicinity of the base of the upper right end portion 251b of the partition plate 250, a circular storage through hole 255 that can hold the eight partition plates 250 together during storage is provided.

  On the other hand, two upper cut grooves 720 ua and 720 ub that are configured so that the upper left end 251 a and the upper right end 251 b of the partition plate 250 are fitted in the edge on the upper end side of the supply cup 72 are provided in the vertical direction. ing. Further, at the edge on the lower end side of the supply cup 72, two lower cut grooves 720sa and 720sb are formed in the vertical direction so that the left lower end protrusion 252a and the right lower end protrusion 252b of the partition plate 250 can be fitted. Is provided. Thereby, the partition plate 250 can be reliably inserted into a predetermined position of the supply cup 72, and does not tilt or shift during use.

  The supply cup 72 fixed to the turntable 71 includes a side wall 721 having a cylindrical shape on the lower side of at least the circular flat portion 71b of the turntable 71, and an inclined side wall 722 having an upper side inclined substantially in a funnel shape. Has been.

  Further, the side edge portion 256 of the partition plate 250 extending from the lower portion of the left and right upper end portions 251a and 251b to the left and right lower end protrusion portions 252a and 252b is inclined at least in a funnel shape when mounted on the supply cup 72. In order to ensure a gap between the inner surface side of the part 722 and a fitting error due to a dimensional error or the like that occurs during the manufacture of each component, the shape extends straight in the vertical direction.

A storage pin 190 for storing the partition plate 250 is attached at a position slightly closer to the steering handle 9 side from the center position of the circular flat portion 71b of the rotary table 71. When the partition plate 250 is not used, the user can hold all the partition plates 250 together by inserting the storage through holes 255 of the partition plate 250 into the storage pins 190, and the user loses them. In addition to preventing this, there is an effect that it can be taken out immediately when necessary.
(4) About the safety cover 400:
As shown in FIG. 5, the safety cover 400 includes an elastically deformable rubber or resin safety cover main body 410 and a safety cover fixing portion 420 for attaching the safety cover main body 410 and fixing it to the protruding portion 203. It consists of and.

  The safety cover fixing part 420 protrudes with the two substantially U-shaped ends separated into two, and each protruding part is provided with one through hole. Specifically, the through holes 421b provided in the pair of lower protruding portions 421a are holes for fixing to the protruding portions 203, and the through holes 422b provided in the pair of upper protruding portions 422a are safety covers. It is a hole formed in the inclined surface in order to fix in the curved state so that the center of the upper surface side of the main body 410 protrudes upward from both ends. That is, the pair of upper protruding portions 422a is inclined with respect to the pair of lower protruding portions 421a. The fastening component 401 is a bolt for attaching the safety cover main body 410 to the safety cover fixing portion 420.

  Thus, the safety cover body 410 completely covers the opening at the upper end of the supply cup 72a when the supply cup 72 has moved to the predetermined position G (see FIG. 2). Can be prevented.

  Further, since the upper protrusions 422a of the safety cover fixing part 420 are inclined, the safety cover body 410 can be fixed in a curved state so that the center of the upper surface side of the safety cover body 410 protrudes upward from both ends. Even if it is a rubber plate-like member and the protruding size of the upper protruding portion 422a is shortened, the front end portion 410a of the safety cover body 410 does not hang downward and interferes with the upper end portion of the supply cup 72. Can be prevented.

  In addition, since the protruding dimension of the upper protruding portion 422a can be shortened in this way, even if the operator accidentally pinches the finger between the supply cup 72a and the safety cover 400, the operator's finger is elastic. The possibility of touching the deformable safety cover body 410 is high, and the possibility of directly touching the upper protrusion 422a of the safety cover fixing part 420 is low, so that the finger can be pulled out immediately and the damage is small. .

Further, as described above, the front end portion 410a of the safety cover body 410 completely covers the opening at the upper end of the supply cup 72a, and the lower end portion 410b is straight along the side wall portion 423 of the safety cover fixing portion 420. The rotary table 71 and the soot support plate 200 protrude downward. Thereby, it becomes possible to cover the gap between the planting part link 424 (see FIG. 1) for adjusting the opening amount of the hopper and the rotary table 71 and the seed vat support plate 200, so that the operator can pinch his hand or the like. It can be prevented.
(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 left-right direction of the traveling body of the seed vat transplanter 1). A cover for covering the space between the lower end of the supply cup 72 protruding to the lower surface side of the rotary table 71 and the seed vat support plate 200, and further partitioning between the rotation drive mechanism 76 and the operator's work position. Yes, 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 the rotary table 71 as viewed from above, with the horizontal direction of the sow transplanter 1 as a reference (see FIG. 4 (a) to (c)). 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 way, the operator is not limited to the work position of the seed vat transplanter 1, but is opposite to the work position (in the present embodiment, the traveling machine body of the seed vat transplanter 1). Even when the operator is on the right side of the turntable 71 with respect to the left-right direction, the operator can be prevented 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.
(6) Regarding the container platform 300:
Here, the configuration of the container platform 300 will be described more specifically with reference to FIGS. 1, 3, 13, 14 (a) and 14 (b).

  FIG. 13 is a schematic view of the folded state of the container platform 300 shown in FIG. 3 when viewed from the rear of the aircraft.

  14A is an exploded perspective view of the container platform 300, and FIG. 14B is an enlarged plan view of a Z portion in a state where the container platform 300 is assembled.

  As shown in FIGS. 1, 3, 13, and 14 (a), the container platform 300 includes a central mounting unit 310 that is disposed above the center of the aircraft and a left-mounted device that is disposed above the left side of the aircraft. The left mounting unit 320 and the right mounting unit 330 are arranged at both end sides of the central mounting unit 310 by the rotation shaft 340. It is connected so that it can rotate. Hereinafter, each unit will be described with reference mainly to FIG.

  As shown in FIG. 14A, the central mounting unit 310 is a frame composed of two support pipe fixing plates 312 that fix the two central support pipes 311a and 311b at a constant interval. Thus, a central mounting frame 313 on which a container (not shown) is placed is fixed at the center of the frame. The center placement frame 313 protrudes from the center support pipe 311a by a distance L toward the front of the machine body.

  Further, rotation shaft support plates 314a1, 314a2, 314b1, and 314b2 having holes for supporting the rotation shaft 340 are provided on the side surfaces of both ends of the two center support pipes 311a and 311b of the central mounting unit 310, respectively. It is fixed. The rotation shaft support plates 314a1 and 314b1 are fixed to the side surfaces facing the front side of the machine body among the left end side surfaces of the central support pipes 311a and 311b, whereas the rotation shaft support plates 314a2 and 314b2 are fixed. Is fixed to the side surface facing the rear side of the airframe among the side surfaces of the right end portions of the central support pipes 311a and 311b.

  As shown in FIG. 1, the central mounting unit 310 includes a first fixed angle 315a for supporting the central mounting unit 310 from below and fixing it to the upper part of the planting transmission case 24 of the airframe, Two fixed angles 315b are provided. The reason why the first fixed angle 315a is bent in a substantially L shape is to prevent interference when the hood covering the engine 2 is removed.

  Next, as shown in FIG. 14 (a), the left mounting unit 320 is a frame composed of a side surface fixing plate 322 that fixes the two support pipes 321a and 321b at a constant interval. A mounting frame 323 for placing a container (not shown) is fixed on the frame. The mounting frame 323 protrudes from the support pipe 321a by a distance L toward the front of the machine body. As will be described later, the mounting frame 323 of the right mounting unit 330 also protrudes from the support pipe 321b by a distance L toward the front of the machine body. For this reason, since the central mounting frame 313 and the left and right mounting frames 323 protrude by the same distance L in the front direction of the machine body, it is easy to move the container placed on the container platform 300.

  The side surface fixing plate 322 is a substantially trapezoidal plate member, and the first upper end edge 322a on the front side and the second upper end edge 322b on the rear side are chamfered except for the central portion of the upper end edge. And inclined. By forming this chamfer, the container can be easily placed on the container platform 300.

  In addition, a rotation shaft 340 having a thread groove formed on the tip side is fixed to the right ends of the two support pipes 321a and 321b of the left mounting unit 320 so as to protrude toward the front side of the machine body. Furthermore, when the folded left mounting unit 320 is unfolded on the lower surfaces of the right ends of the two support pipes 321a and 321b of the left mounting unit 320, the upper edge 324a of the center supporting pipes 311a and 311b A stopper 324 that contacts the lower surface of the left end is fixed. With this configuration, as shown in FIG. 14A, when assembling the center mounting unit 310 and the left mounting unit 320, the ends of the two rotating shafts 340 are connected to the rotating shaft support plate. By moving the holes 314a1 and 314b1 from the lower right side of the drawing to the left side of the drawing in the drawing, both of them can be fitted into the holes at the same time, and the assembly work can be easily performed. . After fitting the rotation shaft 340 into the hole, a nut 341 and a nut 342 with a spring spring are fitted from the tip, and locked so as to be rotatable.

  Thereby, when the left and right mounting units are folded, the sliding surfaces of the rotation shaft support plates 314a1, 314b1, 314b2, and 314a2 can be prevented from being scraped, and the rotation support force is not reduced.

  The configuration of the right mounting unit 330 is exactly the same as that of the left mounting unit. Therefore, the arrangement after the assembly is different from the left mounting unit 320 in that the tip of the rotation shaft 340 faces the rear direction of the machine body, but the effect at the time of assembly is the same as the content described in the left mounting unit 320. It is. In addition, since the left and right mounting units can be used in common, the types of parts can be reduced.

  II. Next, operation preparation of the seed vat transplanter 1 of the present embodiment and operations centering on the seed vat supply unit 70 and the planting tool 26 in the transplant operation will be described with reference to the drawings.

  First, since the container platform 300 is folded as shown in FIG. 13, the operator places the left mounting unit 320 and the right mounting unit 330 around the rotation shaft 340 in order to expand the container mounting table 300. As shown in FIG. As a result of the rotation, when the left and right mounting units 320 and 330 come to a substantially horizontal position, the upper edge 324a of the stopper 324 comes into contact with the lower surfaces of both ends of the central support pipes 311a and 311b of the central mounting unit 310, Stop at that position.

  Next, in order to place the container (not shown) containing the seeds on the container platform 300, the operator places the container from the side fixing plate 322 side of the left mounting unit 320, for example, support pipes 321a and 321b. Slide one on top of the other. At this time, the corners of the first upper end edge 322a and the second upper end edge 322b of the side surface fixing plate 322 are both chamfered, so that when the container is placed, the work is smoothly performed without being caught.

  When the seed culm as a transplant object is smaller than the standard size, the partition plate 250 is attached to the supply cup 72.

  Since eight partition plates 250 of the same number as the supply cups 72 are collectively held by the storage pins 190 of the rotary table 71 (see FIG. 5), these are extracted from the storage pins 190 and shown in FIG. Similarly, the partition plate 250 is inserted in the direction of arrow D until the left and right upper end portions 251a and 251b of the partition plate 250 are completely fitted into the upper cut grooves 720ua and 720ub of the supply cup 72. In the process of insertion, when the protrusions on the left and right lower end portions 252a and 252b of the partition plate 250 move in contact with the inner peripheral surface of the cylindrical side wall portion 721, they are slightly deformed in the direction of the cut portion 254, so that the movement is smooth. When the lower end of the supply cup 72 is reached, the protrusions of the left and right lower end protrusions 252a and 252b are removed from the deformation and are fitted into the lower cut grooves 720sa and 720sb. Thereby, the upper end and the lower end of the partition plate 250 are reliably positioned in the supply cup 72, and the position shift to a horizontal direction does not arise. In addition, since the inclined end surfaces 253 a and 253 b are formed on the protrusions at the lower end of the partition plate 250, the upward movement can be performed smoothly, so that the partition plate 250 can be easily taken out from the supply cup 72.

  Thereby, the partition plate 250 is attached to a position offset in the direction along the rotation direction of the rotary table 71 from the center of the supply cup 72 as shown in FIGS.

  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 worker is located in the work space on the left side of the seed vat transplanter 1, for example, and the safety cover 400 is installed in the supply cup 72 that rotates as the rotary table 71 rotates while keeping pace with the forward movement of the traveling machine body. The seed pods in the container are replenished by hand to the supply cup 72 that has already passed through the predetermined position G (see FIG. 2) and has already been supplied to the planting tool 26 side and emptied. To do.

  In the present embodiment, since the case of transplanting small-sized seed pods is described, the partition plate 250 is already attached to the supply cup 72 as described above, and the storage space is divided into two. Accordingly, as shown in FIG. 7, the operator can move the rear side of the partition plate 250 with reference to the wider storage space 723 of the supply cup 72 partitioned by the partition plate 250, that is, the rotation direction E of the rotary table 71. The seeds C will be replenished. Therefore, by attaching the partition plate 250, the position of the end on the transport upper side of the space for accommodating the seed potato C is moved from the position of the end of the rotation upper side of the rotary table in the supply cup 72 to the position of the partition plate 250. Will be changed.

  By repeating the replenishment operation of seed potato C in this manner, the eight supply cups 72 are sequentially replenished with seed potato C. In addition, if the partition plate 250 is inserted in the center position of the supply cup 72, an operator will be wondering which space of the supply cup 72 divided into two in the center should be replenished with seeds C. However, as described above, since the partition plate 250 is inserted so as to be offset to one side, once it is understood that the large storage space 723 will be replenished with the soy sauce C, there will be no doubt about the replenishment location of the soot seed C. .

  As described above, since the safety cover 400 is installed, it is possible to prevent a finger or the like from entering the supply cup 72a passing through the predetermined position G by mistake while the worker is replenishing seeds. Assuming that the safety cover 400 is not installed, if a finger or the like accidentally enters the supply cup 72a, the opening edge on the lower surface side of the supply cup 72a and the inner peripheral edge of the supply port 201 There is a possibility of fingers being caught between them.

  Furthermore, since the safety cover body 410 is made of an elastically deformable member, even if an operator accidentally puts a finger between the supply cup 72a and the safety cover body 410, the safety cover body 410 is 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 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 soot 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. 2) by the rotation of the turntable 71.

  Further, as described above, the operator replenishes the small seed potato C into the wider storage space 723 of the supply cup 72 partitioned by the partition plate 250 as shown in FIG. When the supply cup 72 rotates in the E direction with the rotation of the rotation, a part of the opening edge portion of the supply port 201 formed in the seed vat support plate 200 relatively comes to the opening end of the lower end of the supply cup 72. Due to the presence of the partition plate 250, the small seed potato C cannot be dropped immediately. When the supply cup 72 further rotates, the supply port 201 relatively moves below the wider storage space 723, so that the small seed potato C falls from the supply port 201 to the planting tool 26 side.

  As a result, even when transplanting small-sized seed pods, the drop timing can be prevented from becoming too early compared to the standard-sized seed pods, and the fall timing can be adjusted appropriately according to the size of the seed pods. . In addition, it is possible to prevent variations in the fall timing due to the small-sized soot rolling in the supply cup 72.

  That is, as shown in FIG. 4, when the supply cup 72a passing through the predetermined position G moves a certain distance after starting to pass right above the supply port 201 (the center of the opening at the lower end of the supply cup 72a is supplied). When the seed vat C, which has been rolling along with the rotation of the supply cup 72a, moves to the location of the supply port 201, the surface of the seed vat support plate 200 until then moves 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.

  Here, the operation of the planting tool 26 will be further described. As shown in FIG. 1, the planting tool 26 is divided into two parts 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 housed and held, it descends as shown by the trajectory B from the top dead center position (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. 2), 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 the driving position of the operator so as to cover each driving unit below the rotary table 71, the operator is prevented from contacting the driving unit. I can do it.

  A farm scene detection 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 is predetermined by the sow seeding planting device 60 according to the rotation of the field scene sensing plate 36 by grounding. The rear wheel 5 is raised and lowered so that the planting depth is reached.

  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, and thus a simple configuration. We were able to provide a seed vat transplanter that could reduce the number of parts.

  Further, by providing the safety cover 400 and the protective cover 50, the worker can work more safely.

  In the above embodiment, a case has been described in which the lower left end protrusion 252a, the right lower end protrusion 252b, and the notch 254 (see FIG. 8) are provided at the lower end of the partition plate 250. For example, the notch 254 is not necessarily required.

  Moreover, although the said embodiment demonstrated the case where the lower left projection part 252a and the right lower projection part 252b (refer FIG. 8) were provided in the lower end part of the partition plate 250, not only this but these, for example, The protruding portion may be omitted. In this case, as shown in FIG. 9A, it is preferable to form a pair of partition plate fixing grooves 721 a and 721 b in the vertical direction on the inner surface of the cylindrical side wall portion 721 of the supply cup 72. Thereby, when an operator mounts the partition plate 250a not provided with projections on the left and right ends of the lower end portion to the supply cup 72, the side edge portion 256 of the partition plate 250a is moved to the partition plate fixing groove 721a, 721b can be inserted, and the upper and lower ends of the partition plate 250a are reliably positioned on the supply cup 72, and no lateral displacement occurs. Here, FIG. 9A is a schematic plan view for explaining the configuration of the supply cup in which the partition plate 250a not provided with the protrusions at the left and right ends of the lower end and the partition plate fixing grooves 721a and 721b are formed. FIG.

  In the above embodiment, the case where the lower cut grooves 720sa and 720sb are provided at the lower end of the supply cup 72 has been described. However, the present invention is not limited to this, for example, as shown in FIG. Instead of the lower slits 720sa and 720sb, holes 720ma and 720mb into which the protrusions 252a and 252b provided at the left and right ends of the lower end of the partition plate 250 are fitted may be provided at the lower end. Here, FIG. 9B is a partially sectional perspective view showing the holes 720ma and 720mb provided in the supply cup.

  In the above embodiment, the upper and lower left and right upper ends 251a and 251b are provided at the upper end of the partition plate 250, and the lower left and right lower protruding portions 252a and 252b and the notch 254 (see FIG. 8) are provided at the lower end. However, the present invention is not limited thereto. For example, if there are left and right upper end portions 251a and 251b, the left lower end protrusion portion 252a, the right lower end protrusion portion 252b, and the notch portion 254 are not necessarily required. do not do. In this case, the cylindrical side wall portion 721 of the supply cup 72 does not require the lower cut grooves 720sa and 720sb (see FIG. 8) and the hole portions 720ma and 720mb (see FIG. 9B). Further, even without the partition plate fixing grooves 721a and 721b (see FIG. 9 (a)), the side edge portion 256 of the partition plate inserted straight downward is even in contact with the side wall portion 721 of the supply cup. For example, since the partition plate itself cannot move in the direction in which the storage space 723 further expands, the fall timing of the seed potato C does not advance earlier than the setting.

  Further, in the above embodiment, when the size of the seed potato C is smaller than the standard, the operator inserts the partition plate 250 into the supply cup 72 and supplies the left and right upper end portions 251a and 251b of the partition plate 250. Although the case where it fits into a pair of upper notch grooves 720ua and 720ub provided in the cup 72 has been described, the present invention is not limited to this. For example, as shown in FIG. Accordingly, the supply cup 72 may be provided with a plurality of pairs of upper cut grooves at different positions so that the insertion position of the partition plate 250 can be changed. FIG. 9C shows an example in which second upper cut grooves 724 ua and 724 ub are provided beside the pair of upper cut grooves 720 ua and 720 ub. In this case, a pair of second lower cut grooves 724sa and 724sb are also provided beside the pair of lower cut grooves 720sa and 720sb.

  Further, in the above embodiment, the shape of the partition plate 250 is such that, in the inserted state, the side edge portion 256 of the partition plate 250 is straightened in order to secure a gap between the inclined surface of the inner wall surface of the supply cup 72. However, the present invention is not limited to this. For example, in order not to provide a gap with the inner wall surface of the inclined side wall portion 722 inclined in a funnel shape of the supply cup 72. In addition, a substantially T-shaped configuration in which side edge portions on both sides of the partition plate 250 are inclined may be employed.

  In the above-described embodiment, the configuration in which the partition plate 250 is inserted straight into the supply cup 72 has been described. However, the present invention is not limited to this. The structure which positions may be sufficient. In this case, since the position of the partition plate 250 on the lower side of the supply cup 72 is the same as that in the above embodiment, the position of the upper cut groove can be further shifted to one side. The opening space in the upper part of the supply cup 72 to be replenished can be secured more widely, and the replenishment work of the seed potato C can be performed more smoothly.

  In the above-described embodiment, the configuration has been described in which a gap is ensured between the partition plate 250 and the inner surface side of the inclined side wall portion 722 of the supply cup 72. However, the present invention is not limited to this. The structure which is not ensured may be sufficient. In this case, when the partition plate is attached to the supply cup 72, no substantial gap is generated between the partition plate and the inner wall surface of the supply cup 72.

  In the above embodiment, the configuration using the partition plate 250 (see FIGS. 5 and 8) has been described. However, the present invention is not limited to this. For example, as shown in FIG. The structure may be covered. In this case, the partition cap 160 includes a ring-shaped cap portion 161 that partially covers the edge of the upper end of the supply cup 72 so as to be rotatable, and a top portion of the ring-shaped cap portion 161. The partition wall 162 is provided on the side surface on the inner peripheral side and partitions the inside of the supply cup 72 in the vertical direction. Here, the function of the partition wall 162 is basically the same except that the left and right projections 252a and 252b and the two notches 254 provided on the partition plate 250 are not provided. The upper end side of the gap between the partition wall 162 and the supply cup 72 is completely closed by the wide portion 163 (corresponding to the portion where the partition wall 162 is provided) of the ring-shaped cap portion 161. Further, a simple unevenness (not shown) as a female screw is formed on the inner wall portion of the ring-shaped cap portion 161, and the outer peripheral edge portion of the opening at the upper end of the supply cup 72 corresponding to this is engaged with it. Simple irregularities (not shown) as male screws are formed. With this configuration, the partition cap 160 is placed over the supply cup 72, the male screw and the female screw are engaged with each other, and the ring-shaped cap portion 161 is rotated in the tightening direction (clockwise direction). The cap 160 can be easily attached to the supply cup 72. As a result, the positional relationship between the partition wall 162 and the supply cup 72 is the positional relationship between the partition plate 250 and the supply cup 72 shown in FIG. Moreover, if the partition cap 160 is rotated in the reverse direction, it can be easily removed.

  Moreover, in the said embodiment, although the structure which uses the partition plate 250 (refer FIG. 5, FIG. 8) was demonstrated, not only this but as the partition plate 170 with a lid | cover as shown in FIG.10 (b), for example. good. In this case, the lid-attached partition plate 170 includes a partition member 171 having the same function as that of the partition plate 250, and a closing lid for closing an unnecessary opening in the supply cup 72 formed integrally with the partition member 171. 172. As a result, it is possible to prevent erroneous replenishment of seed potato C into unnecessary openings. Further, by increasing the thickness of the closing lid 172 in the downward direction (for example, up to the upper ends of the two cut portions 254), the strength of the partition member 171 is increased and the deformation becomes difficult. Therefore, it can prevent that the partition member 171 is pushed and deform | transformed with the weight of the seed | species seed C which has been replenished, and is erroneously supplied to the planting tool 26 side at an earlier timing than an appropriate fall timing. In addition, the same code | symbol was attached | subjected to the site | part which has the same function as said partition plate 250. FIG.

  Further, in the configuration example of the partition cap 160 shown in FIG. 10A, the wide portion 163 is provided, and the unnecessary opening on the upper end side of the gap between the partition wall 162 and the supply cup 72 is completely covered. However, the present invention is not limited to this. For example, as shown in FIG. 10C, the partition cap 180 having a configuration in which the opening 183 a on the upper end side of the gap between the partition wall 162 and the supply cup 72 is not covered. It may be. In this case, when the rotation angle of the partition cap 180 can be fixed even at a position rotated 180 degrees from the position shown in FIG. The transplant object can be replenished to the opening 183a side. As a result, even when transplanting a smaller-sized seed soy C or another transplant object, the drop timing can be controlled more appropriately. In this case, erroneous supply of the transplanted object such as seed potato C can be prevented by the configuration including a lid (not shown) that covers the opening 183b that is not used.

  Further, in the configuration example of the partition cap 160 shown in FIG. 10A, the cap portion 161 is rotated clockwise to completely tighten the male screw and the female screw so that the partition cap 160 can be easily supplied to the supply cup 72. In the fixed position, the positional relationship between the supply cup 72 and the partition wall 162 is the same as the positional relationship between the supply cup 72 and the partition plate 250 approaching the supply port 201 shown in FIG. Explained the case. However, the present invention is not limited to this. For example, as a modified example (not shown) of the partition cap 160, the ring-shaped cap portion 161 placed on the opening at the upper end of the supply cup 72 can be rotated and fixed arbitrarily by screwing or the like. By adopting a configuration that can be fixed at the rotational position, it is possible to fix it at an arbitrary clockwise rotational position on the basis of the positional relationship between the partition plate 250 and the supply cup 72 shown in FIG. It can also be fixed at an arbitrary clockwise position. Thereby, according to the size and shape of the transplant target object which uses seed soy C as an example, it becomes possible to adjust fall timing more finely.

  In the above embodiment, as a method for storing the partition plate 250, the circular storage through hole 255 provided in the partition plate 250 is provided in the storage pin 190 (see FIG. 5) provided on the rotary table 71. The configuration for storing by inserting has been described. However, the configuration is not limited thereto, and for example, a configuration in which a storage pin 190a is provided on the lower side of the outer peripheral surface of the support column 93 as shown in FIG. In this case, since the partition plate 250 is stored below the rotary table 71 and the seed vat support plate 200, it is possible to prevent deterioration due to irradiation of direct sunlight during the storage period of the partition plate 250. Therefore, in this case, as the material of the partition plate 250, it is not necessary to use a material having a very excellent weather resistance, so that the range of selection of the material is widened and the cost is reduced.

  In the above-described embodiment, the configuration in which the partitioning plate 250 is provided with the circular storage through hole 255 for storage has been described. However, the present invention is not limited to this. For example, FIG. 11B and FIG. As shown, the storage through-hole 255 may be a rectangular storage through-hole 255a (see FIG. 11 (b)) that allows a resin band for bundling to pass through, or a round bar-shaped storage pin 190, Even when the partition plates 250 are bundled by 190a, the storage through-hole 255b (see FIG. 11 (c)) having a shape in which a round hole is notched may be used. Furthermore, a tap hole (not shown) provided with a tapping groove may be employed as the storage through hole. In this case, the partition plates 250 can be fixed together with bolts. Further, by adopting a bolt structure in which a groove that fits with a tapping groove is formed on the surface of the pin as a storage pin, it can be fixed together in a specific storage location.

  Moreover, although the said embodiment demonstrated the case where it was the structure which curved so that the center of an upper surface side might protrude upward from both ends, as shown to FIG. 6 (a), FIG.6 (b) as the safety cover 400. For example, as shown in FIGS. 12 (a) and 12 (b), a rubber or resin safety cover body 410 that can be elastically deformed and a front end portion 410a of the safety cover body 410 on the lower surface side are shown. The support rod 451 may be used for the support. In this case, as shown in FIGS. 12 (a) and 12 (b), the safety cover fixing portion 460 bent in a substantially U shape has a pair of lower protruding portions 421a and a pair of lower protruding portions. It is comprised from the upper side protrusion part 461 arrange | positioned in parallel with respect to the part 421a, and the side wall part 423 located in the middle of these upper and lower protrusion parts, One end of the support bar 451 is located in the center position of the upper surface of the upper side protrusion part 461. Is fixed by welding. As described above, the front end portion 410a of the safety cover body 410 is supported by the support rod 451 from the lower surface side, so that the front end portion 410a of the safety cover main body 410 does not hang downward and the upper end portion of the supply cup 72. Can be prevented from interfering with. In addition, the same code | symbol was attached | subjected to the fundamentally same part as the safety cover 400 shown in FIG. Here, FIG. 12A is a perspective view of a modified example of the safety cover 400 described in FIG. 6, and FIG. 12B shows the safety cover 450 shown in FIG. FIG.

  Moreover, in the said embodiment, although the structural example shown to FIG.1, FIG.3, FIG.13, FIG.14 (a), (b) was demonstrated as the container mounting base 300, it is not restricted to this, For example, FIG. The container mounting table 350 having the configuration example shown in FIG. 16 may be used. FIG. 15 is a plan view of the container platform 350, and FIG. 16 is an enlarged perspective view of a Z portion shown in FIG. In this case, the main difference from the above configuration example is the structure of the rotating portion (the Z portion in FIG. 15) in which the central mounting unit 360, the left mounting unit 370, and the right mounting unit 380 are connected. is there. In FIG. 15, the same components as those of the container platform 300 of FIG.

  As shown in FIG. 16, through holes 365 are provided at both ends of the two central support pipes 361a and 361b of the central mounting unit 360, respectively. In this configuration, the member for fixing the two central support pipes 361a and 361b is a pipe-shaped support pipe fixing member 362, unlike the plate shape of the above configuration example (see FIG. 14). Further, on the inner side surface of the end portion of the two support pipes 371a and 371b constituting the left mounting unit 370 on the side of the central mounting unit 360, a stopper that functions as a stopper and a function of the rotating shaft support plate. A cum-rotating shaft support plate 372 is fixed by welding. The stopper / rotation shaft support plate 372 is provided with a round hole 373 at substantially the center, and a stopper angle portion 374 extending from the round hole 373 to the lower surface side of the support pipe fixing member 362 of the central mounting unit 360. Is formed.

  Under the above configuration, when assembling the central mounting unit 360 and the left and right mounting units 370 and 380, a bolt 390 as a rotating shaft is connected to the through hole 365 and the round hole 737 via the washer 391. The nut 341 and the nut 342 with a flat spring are tightened from the tip thereof and fixed so as to be rotatable.

  In this case as well, the left mounting unit 370 and the right mounting unit 380 can be handled as common components, so that the types of components can be reduced as in the above configuration example. Further, by using the stopper / rotation shaft support plate 372 which has both the function of the stopper and the function of the rotation shaft support plate, compared with the configuration example shown in FIG. Furthermore, the number of parts can be reduced.

  With such a configuration, in order to unfold the container platform 350 from the folded state, when the left and right placement units 370 and 380 are rotated around the bolt 391 of the rotation shaft (see arrow Y in FIG. 16). When rotated to the horizontal position, the upper end edge 374a of the stopper angle portion 374 comes into contact with the lower surface of the support pipe fixing member 362, and the rotation is stopped, and the unfolding operation is completed.

  Moreover, in the said embodiment, although the structure which can attach the partition plate 250 or the partition cap 160 was demonstrated, it is not restricted to this, For example, the supply cup of this invention which uses the partition plate 250, the partition cap 160, etc. as an example, The structure which is not provided with the change member which can change the storage space which accommodates a transplant target object may be sufficient. Even in this case, it is possible to provide a transplanter capable of reducing the number of parts by eliminating the need for the opening / closing lid of the supply cup while providing a configuration in which the transplant object can be supplied appropriately and smoothly. Furthermore, even if the safety cover 400 and the protective cover 50 are not provided, the same effect as described above is exhibited.

  Moreover, although the said embodiment demonstrated the structure provided with the safety cover 400 and the protective cover 50, it is not restricted to this, For example, the structure provided with any one or the structure which does not have both may be sufficient. Even in this case, it is possible to reduce the number of parts by eliminating the need to open and close the supply cup 72, while allowing the seed pod to be properly and smoothly supplied, and to drop onto the planting tool 26 according to the size of the seed potato C. It is effective in providing a transplanter that can adjust the timing. Here, in the case where the safety cover 400 is not provided, the inner peripheral edge portion of the supply port 201 of the seed support plate 200 may be covered with an elastic member such as rubber. Thereby, even if an operator's finger | toe etc. are pinched, damage can be reduced and at the same time, it can prevent that the surface of the seed soot C is damaged when the seed soot C falls from the supply port 201.

  In the above-described embodiment, the configuration in which the bearing member 76g passes through the through hole 202 of the seed support plate 200 has been described. However, the configuration is not limited thereto. For example, the outer peripheral surface of the bearing member 76g is formed on the inner peripheral edge of the through hole 202. The structure fixed by welding etc. may be sufficient.

  Moreover, although the said embodiment demonstrated the case where the length of the skirt of the protective cover 50 was the same length regardless of a place, it is not restricted to this, For example, the 1st fixing member 51a to the 2nd fixing member Up to 52a, the length of the hem is the same as that shown in FIG. 4, and the length of the hem may be shortened from the second fixing member 52a to the third fixing member 53. . In this case, the protection range of the protective cover is such that the hem is elongated at the work position side where the planting tool 26 is in the vicinity, and the supply cup 72 protruding at least on the lower surface side of the turntable 71 is at the opposite side to the work position. By setting it as the length of the skirt which can cover the space between a lower end and the seed vat support board 200, the effect that a substantially equal safety can be ensured with a smaller component is exhibited.

  Moreover, in the said embodiment, when the 1st plate-shaped member 211 and the 2nd plate-shaped member 212 serve also as the function as a member for attachment of the protective cover 50, and also the function which reinforces the seed support plate 200 However, the present invention is not limited to this, and for example, it may not have a reinforcing function, and only the function of the attachment-only member of the protective cover 50 may be used.

  In the above embodiment, the scraper 73 is made of hard rubber. However, the present invention is not limited to this. For example, the scraper 73 may have a brush-like configuration or a plate-like configuration that does not deform. Anything is acceptable.

  Moreover, although the said embodiment demonstrated the structure which used the rectangular-shaped 1st and 2nd plate-shaped member 211,212 as the other end side of the protective cover attachment member of this invention, it is not restricted to this, For example, a cross section However, a configuration using a rectangular or circular pipe or bar may be used.

  Further, 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 is applicable and exhibits the same effects as described above.

  Moreover, although the said embodiment demonstrated the case where a seed vase was transplanted, it does not restrict to this, For example, by comprising the supply cup 72 in the size which the standard 55 diameter cup (illustration omitted) of a vegetable seedling enters. Vegetable seedlings can be planted.

  The transplanter according to the present invention can reduce the number of parts by eliminating the need for an open / close lid of the supply cup while having a configuration capable of appropriately and smoothly supplying the transplant object, and also according to the size of the transplant object. Thus, it is possible to adjust the timing at which the transplant object falls from the supply cup to the planting tool through the supply port, and is useful as a seed and soy transplanter or a bulb transplanter.
