  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  In FIG.1 and FIG.2, the side view and top view of the transplanter of this embodiment are shown. The left and right directions in the forward direction of the transplanter are referred to as left and right, respectively, and the forward and backward directions are referred to as forward and backward, respectively.

  The transplanter 1 includes an engine 2 and a transmission case 3 at the front, a pair of left and right front wheels 4 and rear wheels 5 as traveling wheels, and a planting device 7, a supply device 6, a pressure reducing wheel 8 and a steering handle 9 at the rear. It is configured with.

  In this transplanter 1, the front wheel 4 and the rear wheel 5 travel between the scissors so that the machine straddles the scissors U in the field, and a transplant object is placed by the transplanting device 7 at the center position in the left-right width direction of the top surface of the scissors. It has come to be planted.

  When the seedling planting device 7 plants a seedling, it penetrates into the soil and enters to open the seedling, so that the seedling planting part is pushed up the soil. As a result, there is a gap around the planted seedling, and the surrounding soil has been unraveled, so the seedling may not be held in the soil as it is, and may fall down due to the influence of wind or the like and come off .

  In order to prevent this, the soil pushed up around the planted seedling is brought to the seedling from above, and the pair of left and right soil covering pressure reducing wheels 8 and 8 for lightly compacting can be rotated by ground contact with the field scene. Provide.

  The left and right pair of soil covering pressure reducing wheels 8 and 8 are made of a light metal such as an aluminum alloy. As a result, the durability is improved as compared with the one made of a synthetic resin such as vinyl chloride, and the weight is somewhat heavier, so that the soil can be more firmly pressed and the fall of the seedling can be prevented.

  The soil covering pressure reducing wheel 8 is a ring body that has a diameter that decreases from the inner side of the body toward the outer side of the body. A shaft hole 81 into which the pressure reducing rotary shaft 80 is inserted is formed at the center of the outer side of the body. Is a cylindrical boss 82. Then, ribs 83 are formed from the hub 82 every 90 degrees in the circumferential direction toward the outer peripheral edge to improve the strength. The rib 83 is narrower than the left and right width of the boss 82.

  A circular soil-proof plate 84 for preventing the entry of soil is provided inside the cover-covering pressure reducing wheel 8 on the outer side of the machine body to prevent soil from entering when the soil-covering pressure is reduced.

  Thereby, since the soil can be prevented from accumulating in the space portion of the soil covering pressure reducing wheel 8 and the pressure reducing load being increased, it is possible to prevent the soil around the seedling from being excessively hardened and adversely affect the growth of the seedling.

  The soil prevention plate 84 is formed with a shaft insertion hole 85 into which the pressure reducing rotary shaft 80 is inserted at the center, and a tie for attaching the soil prevention plate 84 to the covering soil pressure reducing wheel 8 at the top and bottom when the attachment hole 85 is attached. Attachment holes 87 and 87 for attaching attachment members 86 such as bands are formed. The fixing member 86 is positioned on the side of the soil covering pressure reducing wheel 8 that does not come into contact with the field scene, so that the fixing part is prevented from being worn and damaged due to contact with the field scene.

  In addition, an assembling convex portion 88 that meshes with the plurality of ribs 83 to prevent rotation of the soil prevention plate 84 is formed on the side (rear surface) of the soil prevention plate 84 that does not contact the farm scene.

  As a result, even if the mounting member 86 is broken and the fixing of the soil prevention plate 84 is loosened, the soil prevention plate 84 can be prevented from moving away from the soil covering pressure reducing wheel 8 and rotating independently. Is prevented from accumulating.

  The pressure-reducing rotation shaft 80 is fixed to the pressure-reducing mounting arm 85 and protrudes toward the inside of the machine body. A scraper 89 that scrapes off the dirt adhering to the surface of the soil covering pressure reducing wheel 8 is provided below the pressure reducing mounting arm 85. At this time, if the scraper 89 is housed in the lower part of the pressure-reducing mounting arm 85, when the soil is accumulated, the soil is accumulated in the lower part of the pressure-reducing mounting arm 85, and it is necessary to spend extra labor for the removal work.

  In order to prevent this, a soil cutout portion 85a is formed at the corner of the pressure reducing attachment arm 85 on the outer side of the machine body so that the soil that the scraper 89 approaches the machine body does not come out from the soil cutout portion 85a and accumulate.

  As a result, clogging of soil is unlikely to occur, and the work time and labor required for the removal work are reduced.

  The left and right ends of the mission case 3 are provided with travel extension cases 10 that can rotate with respect to the mission case 3, respectively, and a travel chain case 11 is attached to each end of the left and right travel extension cases 10. Therefore, the power in the transmission case 3 input from the engine 2 is transmitted to the traveling chain case 11.

  A pair of left and right rear wheels 5 which are traveling wheels are respectively attached to the left and right outer sides of the rotating tip of the traveling chain case 11, and the airframe travels by driving the pair of left and right rear wheels 5. Therefore, the transmission case 3 is a transmission device that is transmitted to the rear wheel 5 as a traveling wheel.

  On the other hand, a front wheel support frame 12 extending in the left-right direction is provided at the lower part of the engine mounting table so as to be rotatable around a rolling shaft 13 (see FIG. 1) in the front-rear direction. It is attached.

  In addition, a main frame 15 is provided at the rear of the horizontal frame 14 disposed in the left-right direction at the rear end of the mission case 3 and extends to a position to the right of the aircraft in the left-right direction. A steering handle 9 is provided at the rear end of the main frame 15, and the steering handle 9 is supported by the transmission case 3 via the main frame 15 and the lateral frame 14.

  Further, a hydraulic elevating cylinder 16 is provided at the rear portion of the mission case 3 in the center in the left-right direction. The hydraulic elevating cylinder 16 is fixedly provided to a hydraulic pressure switching valve portion 17 attached to the mission case 3, and is provided to the hydraulic pressure switching valve portion 17 for switching the hydraulic pressure from the hydraulic pump attached to the mission case 3. It operates by operating the operation valve.

  Further, a horizontal rod 19 extending left and right is provided at the cylinder rod end of the hydraulic lifting cylinder 16, and rear wheel lifting rods 20 and 21 are pivotally attached to the left and right ends of the horizontal rod 19, respectively, and the other ends of the rods 20 and 21. Is pivotally attached to the upper arm 10a attached to each traveling extension case 10, and the reed 19 and the traveling extension case 10 are connected.

  Therefore, the traveling chain case 11 is rotated around the left and right output shafts of the transmission case 3 via the horizontal bar 19 and the rear wheel lifting rods 20 and 21 by the expansion and contraction of the hydraulic lifting cylinder 16. Thus, the rear wheel 5 is moved up and down to raise and lower the machine body.

  Further, a horizontal hydraulic cylinder 22 that is actuated by hydraulic pressure from a hydraulic pump is provided in the middle of the rod 20 so that the left rear wheel lifting rod 20 extends and contracts. The left rear wheel 5 is moved up and down with respect to the vertical position of the rear wheel 5 so that the airframe can be maintained in the horizontal direction regardless of the unevenness of the troughs.

  A pendulum-type left / right tilt sensor 23 is provided on the right side of the mission case 3, and the horizontal hydraulic cylinder 22 is moved via a horizontal operation valve provided in the hydraulic pressure switching valve unit 17 by the detection of the left / right tilt sensor 23. It is configured to operate and maintain the aircraft horizontally.

  The planting device 7 according to the present embodiment is a planting system in which power from the mission case 3 is provided on the rear side of the mission case 3 so as to plant the transplanted objects such as vegetable seedlings one by one in the groin of the field. It is transmitted and operated via a transmission case 24 and a planting device drive case 25a attached to the planting transmission case 24.

  The planting device 7 includes a cup-shaped planting tool 72 having a sharp tip and a link mechanism 75 that operates to move the planting tool 72 up and down. As shown in FIG. 1, the tip of the planting tool 72 is repeatedly actuated in the direction of the arrow in the drawing by drawing a generally elliptical locus B as shown in FIG.

  A rotating seedling frame 100 capable of supporting a plurality of seedling boxes 38 in an inclined posture in which the vertical direction is the longitudinal direction is provided on the upper part of the supply rotating shaft 66f that is the center of the supplying device 6.

  As shown in FIG. 22, the rotating seedling frame 100 is rotatable above the supply rotation shaft 66 f independently of the supply rotation shaft 66 f, that is, a rotation shaft that can rotate regardless of the drive rotation of the supply device 6. 101 is provided, and inclined support arms 102 for supporting the seedling box 38 in an inclined posture are provided on the circumference of the rotating shaft 101 at predetermined intervals. In FIG. 22, the predetermined interval is 120 degrees, and the three seedling boxes 38 can be supported. However, the predetermined intervals may be arranged every 90 degrees so that the four seedling boxes 38 can be supported.

  The inclined support arms 102 are spaced apart in the vertical direction so that the seedling box 38 is inclined toward the outer peripheral edge of the supply device 6 toward the lower side of the body. Arranged and configured. In this inclined support structure, the upper structure 103 located on the upper side is the shortest, the middle structure 104 is next short, and the lower structure 105 is the longest. Since these lengths need to be long enough to support the seedling box 38 in an inclined posture, no extreme difference is provided.

  Further, if the lower end side of the seedling box 38 protrudes outside the outer peripheral edge portion of the supply device 6, the upper opening portion of the supply cups 62 is covered, so that it becomes difficult to introduce the seedling. In order to prevent this, the length of the plurality of inclined support structures 103, 104, 105... Is set to a length at which the lower end portion of the seedling box 38 becomes an inclination angle positioned inside the outer periphery of the supply device 6.

  Of the plurality of inclined support structures 103, 104, 105..., The lower structure 105 is provided so as to be spaced apart from the lower end portion of the rotating shaft 101 to some extent upward, and the seedling box 38 is an opening of the supply cup 62. It is configured to prevent the part from being blocked and to prevent the seeding operation.

  The rotary shaft 101 is provided at the upper part of the supply rotary shaft 66f, the lower half rotates together with the supply rotary shaft 66f, and the upper half is rotatably mounted on the non-rotating bearing member 106, and the operator rotates it by hand. It is set as the structure made to do.

  The rotating seedling frame 100 having the above-described configuration allows the operator to take out the seedling from the seedling box 38 in an inclined posture, so that the seedling can be easily taken out and the working efficiency is improved, and the seedling is difficult to fall from the seedling box 38. There is no need to collect the seedlings.

  Further, since the rotating seedling frame 100 is provided above the supply device 6, an operator standing on the side of the supply device 6 can put the seedling into the supply device 6 with a minimum operation, so that work efficiency is improved. In addition to the improvement, the timing of putting the seedling into the supply cup 62 is not delayed, and the occurrence of a missing line where the seedling cannot be planted is prevented.

  The plurality of inclined support structures 103, 104, 105,... Are made of a telescopic rod, and the amount of protrusion from the rotating shaft 101 can be changed. By making the angle easy to take, it is possible to further improve the work efficiency and more reliably prevent the seedling from falling.

  Furthermore, since the angle of the seedling box 38 can be changed, the angle of the seedling box 38 that supplies the seedlings and the other seedling box 38 are made different so that the fall of the seedling can be prevented and the seedling can be easily taken. It is also possible.

  In addition, by providing the rotary shaft 101 to be rotatable, after the seedling of one seedling box 38 is used up, the rotary shaft 101 can be rotated to place another seedling box 38 close to the operator. Therefore, the work required for moving the seedling box 38 is greatly simplified, and the work efficiency can be improved and the work time can be shortened.

  The rotary seedling frame 100 has a low position depending on the operator, and it may be difficult to take out the seedling from the seedling box 38. In preparation for such a situation, as shown in FIGS. 23A and 23B, a spacer rod 107 may be added between the lower portion of the rotating shaft 101 and the bearing member 106 so that the length can be adjusted.

  As shown in FIG. 23 (b), the spacer rod 107 has an insertion hole 107 a on the upper side and an insertion protrusion 107 b on the lower side. The diameter of the insertion protrusion 107b is substantially the same as that of the insertion port (not shown) of the rotary shaft 107, and is also substantially the same as that of the insertion hole 107a. In addition, the diameter of the insertion port of the rotating shaft 107 and the insertion hole 107a is approximately the same diameter as the insertion protrusion at the upper end of the supply rotating shaft 66f.

  Thereby, since the spacer rod 107 can be easily provided between the rotating shaft 101 and the supply rotating shaft 66f, the efficiency of the work height adjustment work is improved. In particular, the efficiency is improved when a plurality of spacer rods 107 are arranged vertically.

  In addition, since the spacer rods 107 can be connected to each other, the vertical length of the spacer rods 107 can be shortened, the working height can be finely adjusted, and the strength of each spacer rod 107 can be increased. it can.

  Alternatively, the rotating shaft 101 is configured to be long in the vertical direction, and a sliding boss 108 that can move up and down along the rotating shaft 101 is provided, and the inclined supporting structures 103, 104, 105. It may be provided.

  Accordingly, the vertical adjustment of the position where the seedling box 38 is supported in the inclined posture by the vertical movement of the sliding boss 108 and the inclination angle adjustment by adjusting the length of the inclined supporting structures 103, 104, 105. It is possible to adjust according to conditions such as the height of the person, and work efficiency is improved.

  The sliding boss 108 is provided with a lock pin 109 for preventing the sliding along the rotary shaft 101 so that it cannot slide up and down unless the operator moves the lock pin 109 to the release position. When configured, the current working height is prevented from changing suddenly. Note that the operation of the lock pin 109 is simplified if, for example, the structure is similar to that of an umbrella opening / closing operation.

  The upper end portion of the rotating shaft 101 is configured to be insertable into the bearing member 106 in the same manner as the lower end portion. Thereby, when the rotating shaft 101 is reversed in FIG. 25, the rotating seedling frame 100 can be disposed upside down.

  By arranging the rotating seedling frame 100 upside down, the upper part of the seedling box 38 is positioned close to the supply rotating shaft 66f and does not cover the upper part of the supply cup 62 of the supply device 6, so that the seedling input operation is not hindered. At the same time, it is easy to see the position where the seedling should be input, so that the work efficiency is improved and the occurrence of a stock loss due to the loss of seedling input is prevented.

  In the above configuration, the rotating seedling frame 100 does not rotate with the supply rotation shaft 66f of the supply device 6, but the bearing member 106 can be rotated separately up and down or both can be rotated by the supply rotation shaft 66f. It is good also as a structure which can be switched by the shifter pin 110 to select and rotates the rotation seedling frame 100 with the supply apparatus 6 in the same direction.

  Thus, the operator can take out the seedlings from the nearest seedling box 38 at the time of supplying the seedlings, so that the seedlings in one seedling box 38 are not taken out intensively, but in order from the plurality of seedling boxes 38. Therefore, the weight of the seedling box 38 is less likely to be biased, and the weight balance of the machine body is not easily lost. Therefore, the planting posture of the planting device 7 is hardly disturbed, the seedling planting posture is stabilized, and the growth of the seedling is improved.

  The supply device 6 includes eight supply cups 62 that receive seedlings at a position above the planting device 7 and transfer the seedlings on the orbit 64, and rotate at a predetermined speed by the rotational power of the rotational drive mechanism 66. Is done. In addition, this rotation operation is made to correspond to the raising / lowering operation | movement of the planting apparatus 7, ie, the timing which a seedling falls from the supply apparatus 6 is synchronized when the planting apparatus 7 exists in the highest position.

  In FIG. 4, the disassembled perspective view for demonstrating each component of the supply apparatus 6 is shown.

  The supply device 6 includes a rotatable rotary table 61 provided above the planting device 7 and arranged in a loop shape with eight supply cups 62 having openings 62a at the upper and lower ends thereof, and the lower side thereof.

Each of the cylindrical supply cups 62 is provided so as to penetrate therethrough. A rotation shaft 66 f for rotating the rotation table 61 counterclockwise by the rotational force from the rotation drive mechanism 66 is fixedly disposed at the center of the rotation table 61.

  The support plate 26 is a disk-shaped plate member having an opening 27 provided at the inherited position G of the planting device 7, and has a protruding portion 29 for fixing the safety cover 40 to the outer periphery thereof. Immediately below the cup 62, it is parallel to the circular flat surface portion (main surface portion) 61b of the rotary table 61, and is fixed to a support column 93 described later by welding. A rotation drive mechanism 66 is provided further below the support plate 26.

  The support plate 26 is a disc-shaped plate having a diameter smaller than the diameter of the rotary table 61 and including the projection area of the lower ends of the eight supply cups 62 arranged in a ring shape, except for the protruding portion 29. A circular opening 27 larger than the diameter of the lower end opening of the supply cup 62 is formed on a part of the plate member, and the inherited position G to the planting hopper 72, that is, the planting hopper 72 is on the upper side. One is formed at a position corresponding to the upper part of the funnel-shaped upper cylindrical portion 71 of the planting hopper 72 when located at the dead point.

  The support plate 26 is arranged in parallel to the main surface of the rotary table 61 at a predetermined distance from the lower edge of the supply cup 62, and the seedling replenished to the supply cup 62 is opened by the opening 27. The supply cup 62 that does not fall from the gap between the support plate 26 and the lower end edge of the supply cup 62 does not fall on the support plate 26 even if it vibrates during operation. An interval that does not exist is secured.

  Here, the protruding portion 29 of the support plate 26 protrudes to the opening 27 by a predetermined dimension on the outer peripheral side in the vicinity, and two through holes 29a for fixing the safety cover 40 with the fastening parts 40a and 40b are provided. ing. The safety cover 40 will be described later.

  The support plate 26 is formed with a slit-like long hole portion 35 along the radial direction that is large enough to effectively discharge dust and the like accumulated on the upper surface thereof and prevent seedlings from falling.

  On the other hand, a rectangular hard rubber scraper 36 is fixedly disposed on the back surface of the rotary table 61 for removing dust from the long hole portion 35 formed in the support plate 26.

  Further, the support plate 26 is supported by a support column 93 disposed rearward from the body of the transplanter 1, and is fixed by welding at the support portion. In addition, the outer peripheral side surface of the bearing member 66g mentioned later is being fixed to the back end 93a of the support | pillar 93 (refer FIG. 4).

  According to the above configuration, the lower end of the supply cup 62 is open, that is, there is no lid, and the support column 93 is directly fixed to the back surface of the support plate 26. The distance from the top dead center of the planting hopper 72 can be made shorter. Note that the opening 62 a may be provided not on the entire bottom surface of the supply cup 62 but on a part of the bottom surface.

  The rotary drive mechanism 66 is connected to the rotary table drive case 25b so that one end of the rotary drive mechanism 66 can be rotated, and the rotational direction transmitting unit 66c is connected to the input side of the rotary direction converting unit 66b. A first gear 66e1 fixed to the output-side rotation shaft 66d arranged orthogonal to the input-side rotation shaft 66b, and a second gear 66e2 arranged to mesh with the first gear 66e1. The second gear 66e2 rotates smoothly counterclockwise.

  Further, a rotation direction conversion unit fixing angle 67 is fixed to the upper surface of the rotation direction conversion unit 66b by a fastening part 67a. Further, the rotation direction conversion unit 66b is fixed to a unit fixing angle 68 fixed to the back surface of the support plate 26 by a fastening part 67b via a rotation direction conversion unit fixing angle 67.

  The bearing member 66g is a bearing member that rotatably supports the rotation shaft 66f of the second gear 66e2. As described above, the bearing member 66g is fixed to the rear end 93a of the column 93 on the lower end side of the outer peripheral side surface thereof. On the other hand, the upper end side of the bearing member 66g passes through a through hole 28 provided in the central portion of the support plate 26, and the rotary shaft 66f protruding upward from the bearing member 66g is fixed to the central portion of the rotary table 61. Has been. Thereby, the turntable 61 is rotatably supported by the bearing member 66g via the rotating shaft 66f.

  As described above, in the supply device 6 described above, when supplying a relatively tall and soft vegetable seedling having a stem, the planting device 6 is inherited because it protrudes from the upper end of the supply cup 62 or falls down. It may not work well. In addition, the seedling may be displaced during transportation, and the root portion may be rubbed and damaged.

  Therefore, according to the transplanter of this embodiment, a sleeve 65 that is longer than the supply cup 62 and has a bottom lid 65b is attached to the inside of the supply cup 62. A sleeve means a sleeve, but in a transplanter, it usually refers to a cylindrical member into which crops such as vegetable seedlings are placed.

  For example, as shown in FIG. 4, the main body portion 65 a (FIG. 5) of the sleeve 65 is taller than the vertical height of the supply cup 62 and has a smaller diameter than the supply cup 62. The overall shape is elongated. The sleeve 65 is attached to the supply cup 62 by making the diameter above or below the sleeve 65 larger than the diameter of the opening 62 a of the supply cup 62 or by sandwiching a cushioning material between the sleeve 65 and the supply cup 62. It will fit and never fall out of the supply cup 62. Alternatively, the sleeve 65 may be a thick sleeve 65 that is in contact with the supply cup 62 and has a small inner diameter.

  FIG. 5 shows a perspective view of the sleeve 65. A simplified plan view is shown in the upper right of FIG.

  When the flange portion 65 d that contacts the inner surface of the supply cup 62 is fixed to the outer surface of the main body portion 65 a of the sleeve 65, the flange portion 65 d is fixed to the inner side of the supply cup 62 by contacting the inner surface of the supply cup 62. Even if the diameter of the upper portion of the sleeve 65 is smaller than the diameter of the lower end portion of the supply cup 62, the flange portion 65d of the sleeve 65 is fitted to the inner wall of the supply cup 62, and the sleeve 65 is connected to the supply cup 62 by the flange portion 65d. Since it is caught, it does not fall from the supply cup 62.

  Further, since the bottom cover 65b is provided at the lower end of the main body portion 65a of the sleeve 65, even a relatively tall and soft seedling can be held in the sleeve 65, so that the root portion of the seedling may be damaged. Absent.

  Further, when the supply cup 62 is transported on the support plate 26 and passes through the opening 27 provided at the inheriting position G, the bottom cover 65b of the sleeve 65 is opened, so that the seedling is smoothly inherited to the planting device 7. Can be done. If a plurality of types of sleeves 65 having different diameters and heights are arranged, an optimum one can be used depending on the type of seedling.

  As described above, the bottom cover 65b of the sleeve 65 is configured to rotate downward and open around the support shaft 65c provided on the upper side in the transfer direction at the opening 27 provided at the joint position G. That is, the supply cup 62 is transported on the support plate 26 and reaches the opening 27. When the entire bottom cover 65b of the sleeve 65 overlaps the opening 27 in plan view, the cover 65b is opened, and the support shaft 65c portion is the opening. When the bottom cover 65b of the sleeve 65 comes into contact with the support plate 26 after passing through 27, the bottom cover 65b is closed.

  As described above, when the mounting position of the bottom cover 65b of the sleeve 65 is determined by the transfer method of the supply cup 62 and the opening / closing method of the bottom cover 65b, the sleeve 65 is correctly set so that the bottom cover 65b opens and closes appropriately. It is necessary to attach to the supply cup 62 in the direction. Therefore, the orientation of the sleeve 65 attached to the supply cup 62 can be easily identified depending on the shape and position of the flange portion 65d. For example, the number of the support shafts 65c may be increased, and the number of the support shafts 65c may be decreased, and the number of the support shafts 65c may be changed. The shape and size of the opposite flange portion 65d may be changed.

  In the example shown in FIG. 5, when three flange portions 65d are provided, the interval between the flange portions 65d on the side of the support shaft 65c is narrowed instead of providing 120 degrees at equal intervals, and the opposite side to the support shaft 65c. The interval between the flange portions 65d is increased.

  With this configuration, the orientation of the sleeve 65 attached to the supply cup 62 can be easily identified. Therefore, it is possible to prevent the sleeve 65 from being attached to the supply cup 62 in the wrong direction.

  Further, the sleeve 65 can be easily put in and out of the supply cup 62 by providing the bottom cover 65 b of the sleeve 65 inside the outer periphery of the collar portion 65.

  FIG. 6 is a perspective view of the sleeve 65 when an identification mark is provided on the outer surface of the main body 65a of the sleeve 65. FIG.

  For example, an identification mark 65f such as an arrow mark may be attached to the outer surface of the main body portion 65a of the sleeve 65 so that the orientation when the sleeve 65 is attached can be understood. You may also add colors and write pictures and characters. With this configuration, since the direction of the sleeve 65 attached to the supply cup 62 can be easily identified, it is possible to prevent the sleeve 65 from being attached to the supply cup 62 in the wrong direction. Further, not only the sleeve 65 but also the outer or inner surface of the supply cup 62 may be provided with a similar identification mark 65f.

  FIG. 7 shows a perspective view of the sleeve 65 when the shape of the main body 65a of the sleeve 65 is changed.

  The shape of the supply cup 62 may be partially changed, and the shape of the main body portion 65a of the sleeve 65 may be changed in accordance with the shape of the supply cup 62 so that the orientation when the sleeve 65 is attached may be known. For example, as shown in FIG. 7, a flat surface portion 62b is provided in a part of a cylindrical supply cup 62, and the main body portion 65a of the sleeve 65 is also provided with a flat surface portion 65aa.

  By attaching the sleeve 65 to the supply cup 62 so that the flat portions of the supply cup 62 and the sleeve 65 overlap each other, it is possible to prevent the sleeve from being attached in the wrong direction. Therefore, also with this configuration, the orientation of the sleeve 65 attached to the supply cup 62 can be easily identified.

  Further, a torque spring 65e that urges the support shaft 65c of the bottom cover 65b of the sleeve 65 in the opening direction of the bottom cover 65b may be provided. When the supply cup 62 is transferred on the support plate 26 and reaches the opening 27, the lid 65b of the sleeve 65 is quickly opened by the action of the torque spring 65e, so that the seedling can be transferred to the planting device 7 more smoothly. Can be done.

  In the configuration in which the seedling box 38 is loaded on the rotating seedling frame 100, it is easy to take out the seedling from the seedling box 38, and it is easy to move the seedling box 38 containing the seedling by rotation, but the seedling box 38 is inclined. In addition to being supported in an unstable posture, the seedlings stored in the seedling box 38 are also easily slipped off. There is a problem that hurts.

  In order to solve this, as shown in FIGS. 1, 2, 7, and 8, the placement table 30 for a transplant object includes L-shaped left and right seedling frames provided in front of the seedling supply device 6. The frames 31 and 31 are disposed above the left and right seedling frame posts 32 and 32 that stand on the upper side of the machine body on the front side of the machine frame from the seedling frame frames 31 and 31. Further, the center position of the mounting table 30 in the left-right direction is on a straight line of a supply rotation shaft 66f provided at the center of the seedling supply device 6, and the left and right center positions of the left and right rear wheels 5, 5 are left and right. Place it on the other side (left side).

  Of the left and right seedling frame frames 31, 31, the portion protruding forward of the aircraft has an inclined posture that is positioned upward as it goes toward the front of the aircraft, and the seedling box 38 that stores the seedlings to be loaded is inclined. It is assumed that the position where the seedling is taken out is moved closer to the operator by moving to the rear side of the machine.

  In addition, the mounting table 30 includes a first mounting frame 33 configured by a wire rod that is long in the left-right direction, and a second mounting unit configured by a wire rod protruding in the longitudinal direction of the machine body within the left-right width of the first mounting frame 33. The frame 34 is configured in combination. The first mounting frame 33 has a larger amount of protrusion on the left and right sides (the right side of the body) than the left and right other sides of the second mounting frame 34, and the front and rear corners at the left and right sides are at right angles. Instead, a taper portion that tilts backward or forward is formed. At this time, the left and right one side ends and the left and right other side ends of the first placement frame 33 are located on the outer side of the left and right front wheels 4 and 4 and the rear wheels 5 and 5.

  Then, on the left and right other sides of the first mounting frame 33 and on the inner side of the machine body from the outer end portion, there are provided front and rear rotational support shafts 35a and 35b, and the front and rear rotational support shafts 35a and 35b are provided. As a rotation fulcrum, a rotation seedling frame 36 that can be deployed toward the outside of the machine body is provided. Of the front and rear rotation support shafts 35a and 35b, the rear rotation support shaft 35b provided on the rear side of the machine body compresses a disc spring or the like by tightening a bolt or the like, or uses a double nut to rotate the seedling. It is assumed that a load adjusting mechanism 35c that increases or decreases the force required to rotate the frame 36 is provided.

  When the rotating seedling frame 36 is rotated outward, the left and right other end portions of the first placement frame 33 are in contact with the inner end portion of the rotating seedling frame 36 in plan view. The rotation of the rotating seedling frame 36 is restricted at that position. Therefore, it does not rotate until the rotating seedling frame 36 is in the downward inclined posture toward the farm field, and the loaded seedling is prevented from falling.

  As described above, the seedlings placed on the mounting table 30 are stood on the left and right other sides of the mounting table 30 and the seedling supply device 6 and behind the rear wheels 5 on the other left and right sides, and supplied to the seedling supply device 6. The operator can perform the strength of the force necessary for the rotation of the rotating seedling frame 36 at the seedling supply operation position. Therefore, it is not necessary to leave the seedling supply work position every time the strength is adjusted, and the work efficiency is improved.

  Further, by providing the rotating seedling frame 36 on the left and right other side of the first placement frame 33 so as to be rotatable, and at a position protruding to the outside of the machine body from the rear wheel 5 on the other side of the left and right other side, The load of seedlings can be increased, the frequency of replenishing seedlings can be reduced, and the position when the rotating seedling frame 36 is unfolded can be set so that the operator can easily take seedlings. improves.

  In addition, when the rotating seedling frame 36 is rotated upwardly from the mounting table 30, the rotating seedling frame 36 does not protrude from the outer side of the mounting table 30. It is done.

  The rotating seedling frame 36 includes a first rotating frame 36a having a U-shape in a plan view formed of a wire rod attached to the front and rear rotating support shafts 35a and 35b, and left and right of the first rotating frame 36a. It is comprised by the 2nd rotation frame 36b comprised in the width | variety and comprised with the wire rod which protrudes in the front-back direction of a body. The second placement frame 34 and the second rotation frame 36b each form a seedling box receiving portion 37 that receives a seedling box 38 that stores seedlings to be stacked, with the front and rear ends bent toward the upper side of the machine body.

  The second placement frame 34 and the second rotation frame 36b are projected from the front and rear ends of the first placement frame 33 and the first rotation frame 36a to the front side and the rear side of the body, and the rear side of the body. Make the amount of protrusion larger than the front side of the aircraft. In addition, the amount of protrusion of the second mounting frame 34 and the second rotating frame 36b to the front and rear sides of the machine body is the same, and there is no difference in the movement of the seedling box 38 between the mounting table 30 and the rotating seedling frame 36. It is configured to facilitate the movement and removal of the seedling box 38, and the work efficiency is configured.

  As a result, the loaded seedling box 38 moves toward the rear side of the machine body and the seedling placement surface is directed toward the worker side, so that the worker can easily take out the seedling and work efficiency is improved.

  Further, as shown in FIGS. 2 and 8, the rear side of the seedling frame 31 on the left and right sides of the machine body and the rotation support shaft 35 b on the rear side are connected by a reinforcing plate 39. The reinforcing plate 39 may be provided to connect the front part side of the seedling frame frame 31 on the left and right sides of the machine body and the rotating support shaft 35a on the front side. If it is provided on the rear side of the machine body where the operator often performs a turning operation and is easily loaded and deformed, the reinforcing effect can be sufficiently exerted, and the turning seedling frame 36 can be prevented from being deformed or damaged. In addition to this, by not providing the reinforcing plate 39 on the front side, the number of parts and the weight of the machine body can be reduced.

  The mounting table 30 has a left-right width of about 3 when the longitudinal direction of the seedling box 38 is placed in the longitudinal direction of the machine body, and the rotating seedling frame 36 has a degree to which one seedling box 38 is placed. If the width is left and right, it is possible to reduce the frequency of replenishing the seedling box 38 to the extent that the effect can be realized while suppressing the amount protruding in the left-right direction from the machine body.

  In addition, the mounting table 30 is configured such that the left and right one side ends of the first mounting frame 33 have the same shape as the left and right other side ends of the first mounting frame 33 and the holes (in which the front and rear rotation support shafts 35a and 35b are mounted). (Not shown) may be formed, and the rotating seedling frame 36 may be rotatably mounted on the left and right sides of the machine body.

  Note that when the rotating seedling frame 36 is simply mounted, the front and rear are reversed, and the front and rear protruding amounts of the second rotating frame 36b are reversed. As shown in FIG. 8, the second rotating frame 36b is mounted so as to be movable (slidable) in the front-rear direction with respect to the first rotating frame 36a, as shown in FIG. The seedling box 38 can be similarly placed regardless of which side is mounted.

  Due to the above, when the operator cannot stand on the left and right sides of the body of the seedling supply device 6 due to conditions such as the dominant hand of the worker and the state of the field in which the work is performed, Since the seedling can be put up while standing, it is possible to cope with various working conditions and the worker can easily work.

  The mounting table 30 and the rotating seedling frame 36 are loaded with a plurality of seedling boxes 38 in the left-right direction of the body, and when there are no seedlings stored in the seedling box 38 on the rotating seedling frame 36, the seedlings that have become empty It is a common operation to remove the box 38 and move the seedling box 38 containing the seedlings loaded on the mounting table 30 to the rotating seedling frame 36. The empty seedling box 38 may be loaded in an empty space on the mounting table 30 by an operator.

  At this time, the seedling box 38 close to the rotating seedling frame 36 arrives without the operator reaching too much, so that it can be easily moved from the mounting table 30 to the rotating seedling frame 36. However, there is a problem in that the seedling box 38 placed on one end of the left and right sides of the machine body is at a position away from the operator, and it is difficult for the operator to move the seedling box 38 unless the hand is greatly extended.

  In order to solve this problem, as shown in FIG. 8, among the second mounting frame 34 constituting the mounting table 30, seedling box transport rollers 40 are rotatably provided at the wire rod portion in the longitudinal direction of the machine body.

  Thus, the seedling box 38 provided on the left and right sides of the mounting base 30 moves to the left and right sides of the body by rotation of the seedling box transport rollers 40 when the adjacent seedling boxes 38 are separated from each other. By moving it to a position where it can be taken without forcibly extending it, the labor of the operator is reduced. When the seedling box 38 does not move, the operator urges the seedling box transport rollers 40 to rotate by shaking the mounting table 30 or the like.

  At this time, since there is a possibility that the seedling box 38 may move to the left and right ends of the machine body, the figure seedling box transporting rollers 40 are allowed to rotate only in the direction in which the seedling box 38 is moved to the other side of the machine body. A one-way clutch (not shown) may be provided.

  In addition, when a seedling box 38 that contains seedlings and increases in weight is placed in order to prevent the seedling box transport rollers 40 from moving the seedling box 38 left and right when an empty seedling box 38 is loaded. If the seedling box transport rollers 40 are submerged and can rotate, the empty seedling box 38 is prevented from moving left and right and dropping from the mounting table 30.

  The front end portions of the mounting table 30 and the rotating seedling frame 36 are disposed on the front side of the body with respect to the rear end portions of the left and right front wheels 4 and 4 and on the rear side of the body with respect to the axles of the front wheels 4 and 4. The part is disposed on the front side of the body with respect to the rear end portions of the left and right rear wheels 5 and 5 and on the rear side of the body with respect to the axles of the rear wheels 5 and 5. Thereby, the mounting table 30 and the rotating seedling frame 36 are arranged between the front wheels 4 and 4 and the rear wheels 5 and 5.

  With the above-described configuration, the mounting table 30 and the rotating seedling frame 36 can be arranged at a position where the front-rear balance of the aircraft is unlikely to fluctuate. However, it is difficult for the aircraft to rise forward and backward, and the planting hopper 72 is prevented from planting seedlings in a forward tilting posture or a backward tilting posture, and the root side of the seedling is evenly covered with soil, and the influence of the temperature is affected. In addition to being difficult to receive, the stem and leaves are not buried in the soil, and the photosynthetic function is not impaired.

  Also, the mounting table 30 and the rotating seedling frame 36 are mounted on the left and right support frames 31 and 31 in a portion that is in a downwardly inclined posture. The end portion is configured to be at the same height as the upper end surface of the supply device 6 or slightly above the upper end surface.

  As a result, when the worker removes the seedling from the seedling box 38 and moves it, the operation of raising the arm above the supply device 6 becomes unnecessary, so the arm is hard to get tired and the labor of the operator is reduced.

  In addition, since the moving time from the seedling box 38 to the supply device 6 is slightly shortened, the sowing time is delayed so that the seedling is not supplied to the planting hopper 72 and the seedling is not planted. Occurrence of the seedling is prevented, and the seedling planting work by hand is not necessary.

  Further, the left and right one side end portions of the mounting table 30, that is, the left and right one side end portions of the first mounting frame 33 are projected outward from the left and right sides of the handle 9.

  As a result, the left and right one side ends of the mounting table 30 become the guard body on the left and right sides of the machine body, so that when the operator is gripping and moving the handle 9, obstacles such as walls and pillars on the side of the machine body If there is an object, the projecting portion of the mounting table 30 comes into contact, so that the operator is prevented from contacting the obstacle.

  The guard body on the left and right sides of the machine body is a rotating seedling frame 36 in the unfolded state, and when the rotating seedling frame 36 is stored, the left and right other side ends of the mounting table 30, that is, the first mounting frame. These are the left and right other side ends of the frame 33.

  The mounting table 30 and the rotating seedling frame 36 are opened at the top, and the seedling in the seedling box 38 to be placed continues to be exposed to sunlight and outside air. In periods when the sunlight is strong or the air is dry, if the working time is long, the seedlings will become sunburned, dry and weak, and the growth after transplanting may be delayed or withered after transplanting. There is. In particular, the seedlings in the seedling box 38 placed on the left and right side end side of the mounting base 30 are likely to be weak because the exposure time of sunlight and outside air is long.

  In order to prevent this, an awning cover 41 having substantially the same left and right length as the left and right widths of the mounting table 30 and the unfolded rotating seedling frame 36, and substantially the same front and rear length, is detachably provided.

  As shown in FIGS. 12 and 13, the sunshade cover 41 includes the left and right side ends of the first mounting frame 33, the front and rear ends of the second mounting frame 34, and the left and right sides of the first rotating frame 36 a. It shall attach and detach using the seedling box receiving part 37 for preventing the seedling box 38 from falling off, which is formed at the other end and the front end of the second rotation frame 36b.

  Specifically, a awning frame 46 is constructed by bridging a first awning frame 44 and a second awning frame 45 in the front-rear direction on an upper end portion of a mounting column 42 having a mounting hook 43 at a lower end portion. It is set as the structure which covers the awning curtain 47 on the top.

  The sunshade curtain 47 hangs down from front to back and left and right of the mounting table 30 and the rotating seedling frame 36 in the mounted state, and covers up to the mounting surface (upper surface) of the seedling box 38 of the mounting table 30 and the rotating seedling frame 36. Shall block sunlight and wind from the side. Further, if the sunscreen curtain 47 is made of white with low transparency, the sunflower is taken in while weakening sunlight, so that the seedlings before transplanting can be photosynthesised, while heat absorption can be weakened by reflection. The rise of the temperature inside can be suppressed and the seedling can be prevented from being weakened by the high temperature.

  Since the mounting table 30 and the rotating seedling frame 36 are configured by combining wire rods, there is a lot of empty space below, and it is easy to receive heat from below when the farm scene is reflected. If a light shielding body (not shown) in which the field scene side (lower side) is painted white is provided on the placement surface of the moving seedling frame 36, the influence on the seedling due to reflection can be suppressed.

  The sunshade cover 41 is provided on the mounting table 30 and the rotating seedling frame 36 so as to be slidable back and forth or left and right, and when the seedling box 38 is placed on or lowered, the upper side of the left and right sides of the body can be opened. To do.

  Thereby, it is not necessary to attach and detach the awning cover 41 when the seedling box 38 is replenished or taken out, and the work efficiency is improved.

  Further, in the sunshade cover 41, on the side of the rotating seedling frame 36 where the operator takes seedlings from the seedling box 38 and supplies them to the supply device 6, the exposure time to sunlight and the outside air is short, and there is a working space for taking out the seedlings. Since it becomes necessary, the awning cover 41 is formed with an open portion 48 that does not cover at least the rear side of the front and rear center position of the rotating seedling frame 36.

  When moving the seedling box 38 from the mounting table 30 to the rotating seedling frame 36, if the sunshade cover 41 completely covers the mounting table 30, the worker reaches the inside seedling box 38. Since it becomes difficult, it is good to enlarge the open part 48 in the rear side of the body of the mounting table 30 and a part of the left and right other side of the body.

  Thereby, since an operator can take out a seedling from the seedling box 38 and move it to the supply device 6 without being hindered by the operation of the sunshade cover 41, work efficiency is improved.

  Further, the sunshade cover 41 can protect the seedling from the influence of sunlight and temperature, so that the seedling is prevented from being weakened before planting, the growth is stabilized, and the planted seedling is prevented from withering. .

  However, even in the above configuration, the sunshade cover 41 is provided on the front side of the front and rear center part of the rotating seedling frame 36. Therefore, when taking out the seedling box 38 from the front side of the machine body, it is necessary to thrust the hand into the sunscreen cover 41. There is a problem that seedlings are difficult to take out.

  In order to solve this problem, as shown in FIGS. 8 and 13, the second rotating frame 36b is slidably attached to the first rotating frame 36a in the front-rear direction, and the seedling box 38 is placed thereon. The second rotating frame 36b is configured to be movable on the rear side of the machine body.

  Thereby, since the seedling box 38 can be moved to the rear side of the machine body from the covering range of the sunshade cover 41, it becomes easy to take out the seedling from the seedling box 38, the work efficiency is improved, and the supply timing of the seedling is improved. Delay is prevented.

  Although the seedling on the front side of the body of the seedling box 38 is still difficult to take out, when the second rotating frame 36b is pulled backward and the seedling box 38 is taken out and rotated 180 degrees, the side with the seedling is below the opening 48, That is, since it faces the rear side of the aircraft, it is easy to take out the seedling.

  The sunshade cover 41 can provide high protection against sunlight and air temperature, but there is a problem that the ease of taking out the seedling and the seedling box 38 is lowered.

  Instead of this, the first mounting frame 33 and the first rotating frame 36a are constituted by hollow pipes, a plurality of water spray holes 49 are formed, and water is supplied from the water spray holes 49 to the seedling box 38. It is good. The first mounting frame 33 and the first rotation frame 36a are connected via the joint pipes 52 in the front and rear directions.

  The left and right traveling chain cases 11, 11 are each equipped with a tank base 51 for loading a water tank 50 for storing water to be supplied to seedlings planted in a farm field. A water supply pump (not shown) is provided for sucking up the water and supplying water near the seedling planting position.

  In this configuration, as shown in FIGS. 14 and 15, one end of the first hose 53 is inserted into one of the left and right water tanks 50, and the other end of the first hose 53 is connected to the front side of the first mounting frame 33. It connects with the connection hole (illustration omitted) of the left-right one side. Further, one end of the second hose 54 is inserted into the connection hole on the left and right side on the rear side of the first placement frame 33, and the other end of the second hose 54 is connected to the water supply pump.

  With this configuration, when the water supply pump is operated, water suction starts from the water tank 50, and the water passes through the first hose 53, the second hose 54, the first placement frame 33, and the first rotation frame 36a. Supplied near the seedling planting position. At this time, water being transported is ejected from the water spray holes 49... And water is supplied to the seedling box 38 loaded on the mounting table 30 and the rotating seedling frame 36.

  Thereby, since water is supplied to the seedling box 38 during the seedling planting operation, water shortage due to drying and growth failure due to high temperatures are prevented.

  The sprinkling holes 49 are very thin (in mm or less) in order to spout water to some extent and prevent the water supplied near the planting position of the seedling from becoming too small. It should be a hole.

  Moreover, since the influence of direct sunlight is not reduced by simply supplying water, a spray nozzle (not shown) for spraying water in a mist form is attached to each spray hole 49... And the mounting table 30 and the rotating seedling frame. It is good also as a structure which covers the circumference | surroundings of 36 with fog and blocks sunlight.

  In the above configuration, water must be passed through the mounting table 30 and the rotating seedling frame 36 as pipes, and it is difficult to remove moisture from the interior after work, and there is a problem that corrosion due to water tends to occur.

  For this reason, as shown in FIG.16 and FIG.17, it is set as the structure which connects the 1st hose 53 to the water supply pump from the water tank 50, and supplies water to the seedling box 38 via the 2nd hose 54 from a water supply pump. The second hose 54 is provided with a holding clip 55 on the front side of the second mounting table 34 and is fixed to the spot with the holding clip 55. In addition, a nozzle is attached to the second hose 54 in order to adjust the amount of water sprayed to the seedling box 38 and the water flow. Moreover, the 1st hose 53 and the 2nd hose 54 are comprised with synthetic resins, such as a vinyl chloride, and make it difficult to deteriorate even if water remains inside.

  As a result, although the mounting table 30 and the rotating seedling frame 36 are exposed to water, the water can be easily removed by sun drying or wiping, so that deterioration in durability due to corrosion is prevented.

  In addition, by fixing the second hose 54 with the holding clip 55, water can be supplied to a specific position, so that the seedling in the seedling box 38 that takes time to be sent to the seedling supply operation is weakened. Is prevented.

  The water supply pump is interlocked with the intermittent planting of the seedling by the planting device 7 and sucks up water at the timing when the seedling is planted, so that it does not always supply water. Therefore, the water supplied from the sprinkling holes 49 and the second hose 54 is intermittently supplied to the seedling box 38 to prevent the seedling from being weakened due to excessive moisture, and the consumption of water in the water tank 50 is reduced. Therefore, it is not necessary to change the water tank 50 frequently.

  When there is no need to supply water by the above-described method, rain dew etc. containing water is suspended from the mounting hooks 31a provided at the lower portions of the left and right support frames 31, 31 so that the operator can Water may be supplied to the seedling box 38.

  The mounting table 30 is provided with seedling box transport rollers 40 to facilitate the movement of the seedling box 38 from the left and right sides of the machine body to the left and right sides, that is, the rotating seedling frame 36 side. In addition to this, as shown in FIGS. 18 and 19, in order to facilitate loading or unloading of the seedling box 38 on the mounting table 30, the upper ends of the seedling box receiving portions 37 before and after the second mounting frame 34, and the first The auxiliary rollers 56 may be rotatably provided in the seedling box receiving portion 37 on one side of the left and right sides of the mounting frame 33.

  Thereby, when the bottom part of the seedling box 38 is brought into contact with the seedling box receiving part 37, the seedling box 38 can be put on the mounting table 30 without being caught and can be pulled up from the mounting table 30, so that the seedling box 38 is unloaded. Is done smoothly.

  The left and right support frames 31, 31 define the vertical height of the mounting table 30, but have a common vertical length on the left and right, so that the mounting table 30 also has to be provided unless the vehicle body 10 is tilted in the horizontal direction. Do not tilt in the left-right direction. Even if the seedling box transport rollers 40 are provided, the seedling box 38 cannot move from the left and right sides of the machine body to the other side of the machine body unless the operator touches it.

  Accordingly, as shown in FIGS. 19 and 20 (a) and 20 (b), the left and right support frames 31, 31 can be independently changed in vertical length, and the vertical length on one side of the left and right sides of the body is set to the left and right sides of the body. When longer than the vertical length on the other side, the mounting table 30 can be in an inclined posture in which the left and right other sides of the body are lowered without tilting the vehicle body 10. Thereby, the seedling box 38 placed on the end of the left and right sides of the machine body can be moved to the left and right other sides of the machine body by the seedling box transport rollers 40 without being touched by the operator, so that the work efficiency is improved. .

  The above-described method is particularly effective when the awning cover 41 is provided and it is difficult for an operator to reach the seedling box 38 inside the awning cover 41.

  In addition, when placing the seedling box 38 that has been exhausted by using up the seedlings, the mounting table 30 and the rotating seedling frame 36 move the seedling box 38 with seedlings to the left and right sides of the machine body, Must be placed in the free space on the side. However, in order to perform this work, the operator needs to move to the left or right side of the supply device 6 or to stand on the vehicle body 10 and place the seedling box 38 on the mounting table 30. Need to spend.

  In order to reduce this work, as shown in FIG. 21, wires extending in the left-right direction are connected to the lower side of the first mounting frame 33 on the front side and the rear side of the first mounting frame 33, An empty box holder hook 57 that can hold an empty empty seedling box 38 may be provided. The empty box placing hook 57 has a U-shape (concave shape) in a side view.

  Thereby, it is not necessary to forcibly place the empty seedling box 38 on the left and right sides of the body of the mounting table 30, and the labor of the operator is reduced.

  Further, it is not necessary to place the seedling box 38 in the field, and the work of collecting the seedling box 38 later becomes unnecessary.

  The transplanter of the present invention can be used as a transplanter for planting various crops such as vegetable seedlings.
