Accordingly, the drop supply positions 39 and 40 can be changed in position by the arrangement pitch in the seedling supply cup 25, and the distance between the left and right drop supply positions 39 and 40 is the first and second seedling supply. The cup 25b, 25c is configured to change by an integral multiple (1 times) of the arrangement pitch (an even multiple (2 times) of the arrangement pitch of the seedling supply cup 25).

  The seedling planting device 23 is intended to move up and down between a beak-shaped seedling planting body 5 whose tip is directed downward, and a position where the lower end of the seedling planting body 5 is above the farm scene and a position below the farm scene. A vertically moving mechanism 4 for moving the seedling planting body 5 up and down, a closed state in which the lower end portion of the beak-like seedling planting body 5 is closed and a seedling is received from above and a seedling can be accommodated inside, and a lower end portion of the seedling planting body 5 Is provided with an opening / closing mechanism 50 that opens and closes the seedling planting body 5 in an open state in which the seedlings opened left and right and accommodated inside can be discharged downward.

  A tension spring 23 a is mounted between the reinforcing frame 92 connected to the machine frame 20 and the left and right seedling planting bodies 5. Accordingly, when the seedling planting body 5 is moved downward by the vertical movement mechanism 4, the pulling spring 23a is planted by the action of the descending moving inertia force being increased by the weight of the seedling planting body 5 and descending faster than a predetermined operating speed. By canceling the body 5 by urging the body 5 upward, the seedling planting body 5 descends smoothly at a predetermined speed. Conversely, when the seedling planting body 5 rises by the vertical movement mechanism 4, the seedling planting body 5 When the pulling spring 23a urges the seedling planting body 5 upward, the lifting force is applied to the seedling planting body 5 at a predetermined speed. Ascend smoothly. Therefore, the right and left seedling planting body 5 moves up and down smoothly, operates a predetermined operating locus at an appropriate operating speed, and can perform a good seedling transplanting operation.

  This transplanter 1 has a configuration of a plurality of planted plants in which a plurality of seedling planting bodies 5 are arranged side by side at set intervals. In this example, it is set as the structure of the two-row planting which arrange | positioned the seedling planting body 5 side by side with the set space | interval at a set interval.

  The two seedling planting bodies 5 are attached integrally to the vertical movement mechanism 4 provided on the left and right side portions of the planting transmission case 22. A beak-like seedling planting body 5 with the tip facing downward is composed of a left seedling planting body 5L and a right seedling planting body 5R, and is divided into left and right parts. The body 5R rotates in the left-right direction to open the lower end. The left and right seedling planting body 5 is configured to vertically move and open and close alternately left and right by the vertical movement mechanism 4 and the opening and closing mechanism 50 and to plant two seedlings in a staggered manner in the field. Therefore, the left seedling planting body 5L and the right seedling planting body 5R accommodate a planted material inside, and by turning each other, open and close the lower part of the planted plant to plant the planted product in the field. It constitutes the body part.

  The seedling guide 51 is a cylindrical body that is provided above the seedling planting body 5 and guides the seedling supplied from the seedling feeding device 24 into the seedling planting body 5. The seedling planting body 5 can be accurately supplied. The width L1 of the upper end opening of the seedling guide 51 is wider than twice the pitch P of the seedling supply cup 25 of the seedling supply device 24 (that is, the width of the bottom ends of the two seedling supply cups 25 arranged side by side. The width is wider than the interval L2.

  The vertical movement mechanism 4 of the seedling planting body 5 is provided on both the left and right sides of the planting transmission case 22. Specifically, the upper and lower lift links 52, 53 are connected to the seedling planting body 5 by attaching the front part to the shaft projecting to the left and right sides of the planting transmission case 22 so that the front part can freely rotate up and down. , A drive shaft 54 that rotates from the side of the planting transmission case 22, a drive arm 55 that is mounted to rotate integrally with the drive shaft 54, a rotation outer peripheral end of the drive arm 55, and the upper side It is comprised with the interlocking | linkage arm 56 connected with the raising / lowering link 52 so that rotation is possible. The rear end portions (rotating tip portions) of the upper and lower elevating links 52 and 53 are rotatably connected to the connecting member 57. The seedling planting body 5 is attached to the connecting member 57.

  Therefore, when the drive arm 55 is driven and rotated by the rotation of the drive shaft 54, the elevating links 52 and 53 move up and down, and the right and left seedling planting body 5 moves up and down. The lower end portion of the seedling planting body 5 is positioned above the field scene at the ascending position of the vertical movement, and the lower end portion of the seedling planting body 5 is positioned below the field scene at the descending position.

  Further, the rotation fulcrum shaft 58 of the upper elevating link 52 is provided at a position that is eccentric from the center axis of the output shaft 59 at the tip of the planting output shaft 59 that projects from the planting transmission case 22 and rotates. The rotation of the planting output shaft 59 moves around the axis of the planting output shaft 59 while rotating with an eccentric amount (the distance between the pivot fulcrum shaft 58 and the axis of the planting output shaft 59) as a radius. When the upper fulcrum shaft 58 moves up and down during the up-and-down movement of the upper elevating link 52, the seedling planting body 5 is tilted back and forth during the up-and-down movement, and the seedling planting body 5 is looped in a side view. It is configured to move up and down along the operating locus.

  Next, the opening / closing mechanism 50 of the seedling planting body 5 will be described. The end of the inner wire of the opening / closing cable 61 is connected to the tip of the left opening / closing arm 60 provided on the upper side of the left seedling planting body 5L, and the right opening / closing arm section provided on the upper side of the right seedling planting body 5R is connected. An end of the outer cable of the opening / closing cable 61 is connected to the tip, and an operating arm 64 is provided that is rotatably attached to a pivot fulcrum shaft 63 pivotally attached to the base of the lower lift link 53. The other end of the inner wire of the opening / closing cable 61 is connected to the distal end portion of the operating arm 64, and the other end of the outer cable of the opening / closing cable 61 is fixed and attached to the machine body side. FIG. 5 shows the left seedling planting device 23, and the right seedling planting device 23 is symmetrical with the left seedling planting device 23, so that the front end portion of the left opening / closing arm portion is shown. The end portion of the outer cable of the opening / closing cable is connected to the end portion, and the end portion of the inner wire of the opening / closing cable is connected to the tip portion of the right opening / closing arm portion. Then, the operating arm 64 is set under the action of a cam attached to rotate integrally with a planting output shaft 59 that rotates and rotates a pivot fulcrum shaft 58 pivotally attached to the base of the upper lift link 52. It is set as the structure rotated to the front side at timing. As a result, when the seedling planting body 5 moves up and down by the drive rotation of the drive shaft 54 and reaches the lowered lower end position, the operating arm 64 is rotated forward by the change of the operating position of the cam, and the outer cable of the opening / closing cable 61 The left and right opening / closing arm 60 and the right opening / closing arm 60 are rotated to the side approaching each other, and the right seedling planting body 5R is rotated to the right. The left seedling planting body 5L rotates to the left, the lower side of the seedling planting body 5 opens to the left and right, and opens downward. Then, the seedling planting body 5 rises and the operating arm 64 rotates to the original position (rear side) with respect to the seedling planting body 5 due to the change in the cam action position, and the inner wire of the opening / closing cable 61 is loosened. The lower part of the seedling planting body 5 opened to the left and right is closed. As a result, the seedling planting body 5 is opened / closed by the opening / closing cable 61. Therefore, the opening / closing cable 61 has a higher degree of freedom of connection than the conventional opening / closing mechanism using a rod or link. The actuating arm 64 can rotate the left seedling planting body 5L and the right seedling planting body 5R in different directions (left and right directions), and a desired opening / closing amount of the seedling planting body 5 with a small amount of actuation of the actuation arm 64 Can be obtained. Note that the left seedling planting body 5 </ b> L and the right seedling planting body 5 </ b> R are urged to rotate by the spring 65 toward the side where the lower portion of the seedling planting body 5 is closed.

  By the way, the cutting blade 113 which cut | disconnects the multifilm laid in the farm field is each provided in the outer surface of 5 L of left seedling planting bodies and the right seedling planting body 5R. The cutting blade 113 has a plate-like configuration formed by an iron plate extending in the left-right direction, and the front and rear center portions of the left seedling planting body 5L and the right seedling planting body 5R (the left seedling planting body 5L and the right seedling planting body 5R , The outermost surface of the left and right outer side) is fixed by welding. The outer edge of the cutting blade 113 includes a gently inclined portion 114 that is located at an upper portion and extends linearly, and a protruding portion 115 that extends linearly following the gentle inclined portion 114. The lower end is located slightly above the lower end of the seedling planting body 5 (the lower ends of the left seedling planting body 5L and the right seedling planting body 5R). The gently inclined portion 114 is along the vertical direction (vertical direction) with the lower portion of the seedling planting body 5 closed. Therefore, in the state where the lower part of the seedling planting body 5 is opened, the gently inclined portion 114 is along the gently sloping direction located on the side farther from the center of the seedling planting body 5 toward the lower side. In addition, the intrusion 115 is in a state in which the lower part of the seedling planting body 5 is closed, and the lower side is along an inclination direction that is located closer to the seedling planting body 5 toward the lower side. Even though the lower portion of the seedling planting body 5 is opened, the rush portion 115 has a slight angle change, but the lower side is along the inclination direction located closer to the seedling planting body 5 and the Regardless of opening and closing, it is a configuration along a tilt direction closer to the horizontal direction than the vertical direction (configuration steeply tilted with respect to the vertical direction).

  Further, when the seedling planting body 5 has entered the soil most deeply (when the seedling planting body 5 that operates in a loop-like locus reaches the bottom dead center position of the operation locus), the entry portion 115 has a field scene (soil surface). ), And the upper and lower middle portions of the gently inclined portion 114 are positioned in the field scene (soil surface). Accordingly, when the seedling planting body 5 with the lower part closed by the vertical movement mechanism 4 moves down and enters the soil, the steeply inclined entry part 115 instantaneously contacts the multi-film laid on the field and breaks. After the multi-film is accurately cut and the plunging portion 115 has plunged into the soil, the lower portion of the gently inclined portion 114 plunges into the soil through the cut of the multifilm formed by the plunging portion 115. Accordingly, since the multi-film is hardly cut after the entry portion 115 has entered the soil, the downward movement resistance of the seedling planting body 5 is reduced. And when the lower part of the seedling planting body 5 opens at the bottom dead center or near the bottom dead center of the operation locus of the seedling planting body 5, the multi-film is further cut by rotating the gentle inclined portion 114 outward in the left-right direction. Extend the multi-film cut. And when the seedling planting body 5 in the state where the lower part is opened by the vertical movement mechanism 4 moves upward and leaves the soil, the gentle sloped part 114 is located on the side farther away from the seedling planting body 5 (outside in the left-right direction). Because it is along the gently sloping direction, the multi-film is further cut to extend the multi-film cut. Therefore, since the multi-film is cut over the downward movement, the opening operation and the upward movement of the seedling planting body 5, the multi-film can be cut by gradually cutting the multi-film, and the multi-film is suddenly cut. It is possible to prevent the discontinuity from propagating and forming an unnecessarily large planting hole in the multifilm. As a result, after transplanting, it is possible to prevent the pieces of multi-film cut more than necessary from contacting the seedlings (crop) and causing heat damage, and to maintain the heat-retaining effect of the multi-film as desired. Can be performed well.

  In the above description, the configuration in which the gently inclined portion 114 extends along the vertical direction with the lower portion of the seedling planting body 5 closed is described. However, when the lower inclined portion 114 is closed with the lower portion of the seedling planting body 5, the vertical direction The lower side of the seedling planting body 5 is opened along the inclined direction that is slightly inclined from the vertical direction and the lower side of the seedling planting body 5, and the lower side is located farther from the center of the seedling planting body 5. It is good also as a structure along the direction which inclines gently.

  In the above description, the configuration in which the cutting blade 113 is fixed to the outer surfaces of the left seedling planting body 5L and the right seedling planting body 5R has been described. However, the cutting blade 113 is fixed to the outer surfaces of the left seedling planting body 5L and the right seedling planting body 5R. You may comprise so that rotation adjustment is possible and position adjustment is possible in the side away from the seedling planting body 5. Considering that the cutting blade 113 smoothly cuts the multi-film in combination with the entry of the lower end of the seedling planting body 5 when entering the farm scene, the cutting blade 113 regardless of the rotation of the cutting blade 113. Since it is better that the lower end of the cutting blade 113 is arranged near the lower ends of the left seedling planting body 5L and the right seedling planting body 5R, the rotation fulcrum of the cutting blade 113 is arranged inside the intrusion portion 115 below the cutting blade 113. It is desirable. Accordingly, for example, the size or shape of the multifilm planting hole can be adjusted in accordance with the dynamic operation trajectory of the seedling planting body 5 in consideration of the material of the multifilm and the traveling of the machine body. A desired hole for planting can be formed. At this time, since the cutting blade 113 is configured to be rotatable with respect to the outer surfaces of the left seedling planting body 5L and the right seedling planting body 5R, the inclination directions of the gently inclined portion 114 and the entry portion 115 can also be adjusted. . For example, in a state in which the lower part of the seedling planting body 5 is closed, the gently inclined portion 114 is configured to follow a tilting direction that is located on the seedling planting body 5 side toward the lower side, or the entry portion 115 is horizontally or substantially horizontal. It can be set as the structure along.

The upper and lower connecting shafts 66 and 67 and the upper and lower elevating links 52 and 53 do not get in the way when a position adjusting shaft 70 described later is slid with the boss 69 as a reference. The left and right plates 68 have a substantially regular triangular shape, and the upper and lower connecting shafts 66 and 67 may be turned upside down so that the connecting member 57 can be attached. The boss hole of the boss 69 has a hexagonal shape (polygonal shape). On the other hand, a hexagonal (polygonal) position adjusting shaft 70 extending in the left-right direction is fixedly provided at the base of the seedling planting body 5. Therefore, the position adjusting shaft 70 is inserted into the boss 69, the seedling planting body 5 is supported by the connecting member 57, and the position adjusting shaft 70 is slid with respect to the boss 69 and moved in the left-right direction. The left and right positions of the body 5 can be changed. The boss 69, the position adjusting shaft 70, the set bolt 71 and the like constitute a planting position changing mechanism A.

The length of the position adjusting shaft 70 is set so that the distance can be changed. That is, the interval between the right and left seedling planting bodies 5 can be changed by an integral multiple (for example, 1 time) of the arrangement pitch in the first and second seedling supply cups 25b and 25c, and the boss 69, the position adjusting shaft 70, etc. The planting position change mechanism which can move the seedling planting body 5 is comprised. The position adjustment shaft 70 can be fixed to the boss 69 by a set bolt 71 provided on the boss 69 so as not to move left and right. When moved to the left and right, the set bolt 71 is loosened and moved. It has become. The set bolt 71 is provided on the rear side of the boss 69 and the position adjusting shaft 70, and can be easily tightened or loosened from the rear side without the lifting links 52 and 53 being in the way. Further, the opposing vertexes of the hexagonal shape (polygonal shape) of the cross section of the position adjusting shaft 70 are arranged vertically, and the section modulus for bending in the vertical direction is improved. The strength required to support the cantilever can be obtained. Further, five grooves 72 serving as a guide for the left and right positions of the seedling planting body 5 are provided on the outer periphery of the position adjusting shaft 70 at an appropriate position, and by aligning the grooves 72 with the ends of the bosses 69, a gap of 300 mm and 350 mm are provided.

Set to the position marked 450mm. Thus, the seedling supply cup 25 can supply seedlings simultaneously without passing through the two seedling planting bodies 5 while serially passing above the two seedling planting bodies 5 without causing seedling supply leakage, The seedling supply cup 25 in which the seedling has not been supplied after passing over the seedling planting body 5 does not occur and the seedling can be supplied in correspondence with the two seedling planting bodies 5 so that the seedling supply operation can be performed with a margin. And a seedling can be reliably supplied to the two seedling planting bodies 5. At this time, the bottom cover 25a of the seedling supply cup 25 with respect to the left seedling planting body 5 opens at the center position of the width L1 of the upper end opening of the seedling guide 51 of the seedling planting body 5, and proper seedling supply and planting can be performed. . The bottom lid 25a of the seedling supply cup 25 with respect to the right seedling planting body 5 opens at a position slightly before the center position of the width L1 of the upper end opening of the seedling guide 51 of the seedling planting body 5, but the upper end opening of the seedling guide 51 The width L1 of the portion is wider than twice the pitch P of the seedling supply cup 25 of the seedling supply device 24 (that is, wider than the distance L2 between the two ends of the two seedling supply cups 25 arranged side by side). Since it is configured, it is possible to supply and plant appropriate seedlings.

  Next, when the 500 mm strip shown in FIG. 13 and FIG. 14 is set, the seedling planting body 5 is immediately below the seedling supply cup 25 when the bottom lid 25a of the seedling supply cup 25 opens at the drop supply positions 39 and 40. It is set to be when it rises to the maximum. At this time, the first moving support 42e for determining the left drop supply position 39 is set at a position marked as 500 mm between the stripes, and the second moving support 42f for determining the right drop supply position 40 is also set between the stripes.

Thus, the seedling supply cup 25 can supply seedlings simultaneously without passing through the two seedling planting bodies 5 while serially passing above the two seedling planting bodies 5 without causing seedling supply leakage, The seedling supply cup 25 in which the seedling has not been supplied after passing over the seedling planting body 5 does not occur and the seedling can be supplied in correspondence with the two seedling planting bodies 5 so that the seedling supply operation can be performed with a margin. And a seedling can be reliably supplied to the two seedling planting bodies 5. At this time, the bottom cover 25a of the seedling supply cup 25 with respect to the left seedling planting body 5 opens at a position slightly past the center position of the width L1 of the upper end opening of the seedling guide 51 of the seedling planting body 5, The width L1 of the upper end opening is wider than twice the pitch P of the seedling supply cup 25 of the seedling supply device 24 (that is, wider than the distance L2 between the two ends of the bottoms of the two seedling supply cups 25 arranged side by side) ), So that appropriate seedlings can be supplied and planted. The bottom lid 25a of the seedling supply cup 25 that supplies seedlings to the right seedling planting body 5 opens at a position slightly before the center position of the width L1 of the upper end opening of the seedling guide 51 of the seedling planting body 5, but the seedling guide The width L1 of the upper end opening 51 is wider than twice the pitch P of the seedling supply cup 25 of the seedling supply device 24 (that is, larger than the distance L2 between the bottom ends of the two seedling supply cups 25 arranged side by side). Since it is configured with a wide width), appropriate seedling supply and planting can be performed.

  Even if the spacing between the planting lines is changed as described above, the width L1 of the upper end opening of the seedling guide 51 is wider than twice the pitch P of the seedling supply cup 25 of the seedling supply device 24 (that is, the two pieces arranged side by side). The width of the seedling supply cup 25 is wider than the distance L2 between both ends of the seedling supply cup 25), so that the seedling supply device 25 can properly supply seedlings from the seedling supply cup 25 to the seedling planting body 5, The planting accuracy can be maintained. Further, the spacing between the planting strips can be easily changed by moving the seedling planting body 5 in the left-right direction and changing the drop supply positions 39 and 40. In particular, even if the spacing between the planting lines is changed, the left and right drop supply positions 39 and 40 can be changed with a simple configuration of changing the positions of the first moving support 42e and the second moving support 42f. The rotation position (phase) of the seedling container 25 can be changed by changing the rotation phase of the winding sprocket 29 relative to the driven sprocket 35 without changing the winding of the chain 34 and the seedling supply cup 25. It becomes easy to change between strips. Note that the position change of the left and right pressure reducing device 110 equipped with the seedling planting body 5 and the left and right pressure reducing wheels 73 can be easily performed by simply sliding the position adjusting shaft 70 and the arm boss 75a of the pressure reducing arm 75b.

  In addition, as shown in the drawing, the left and right pressure reducing wheels 73 for suppressing the soil around the seedling while covering the surrounding area of the planted seedling are provided on the right side of the right and left seedling planting body 5, respectively, The roots of the seedlings that have been planted are crushed from both the left and right sides to promote survival.

  Here, the support structure of each left and right pressure-reducing wheel 73 of the left and right pressure-reducing device 110 will be described. A pressure-reducing arm shaft 74c having a regular hexagonal axis configuration along the horizontal direction is provided on a left and right support arm 74b extending from the pressure-reducing frame 74a fixed to the body frame 20 in a lateral direction and extending rearward of the body. . Then, left and right pressure-reducing wheels 73 are provided at the rear part of the left and right pressure-reducing arms 75 so as to be freely rotatable. As a configuration in which the pressure suppression arm shaft 74c is passed through a circular through hole 75b provided at the front end portion of the end portion 75a, the left and right arms 75 have a configuration in which the rear portion freely rotates up and down with the pressure suppression arm shaft 74c as a rotation fulcrum. It has become.

  On the other hand, a slide boss 75d penetrating the regular hexagonal hole 75c in the left-right direction is disposed inside the U-shape of the rotation base end 75a in a plan view and is externally fitted to the pressure-reducing arm shaft 74c so as to be able to move only to the left and right. Has been placed. That is, a regular hexagonal hole 75c formed through the slide boss 75d in the left-right direction is externally fitted to a regular hexagonal pressure-reducing arm shaft 74c, and the pressure-reducing arm shaft 74c is tightened by tightening a set bolt 75e. The movement can be fixed in the axial direction. Accordingly, by tightening the set boss 75e and fixing the slide boss 75d on the inner side of the rotation base end portion 75a of the pressure reducing arm 75 to the pressure reducing arm shaft 74c, the pressure reducing arm 75 moves in the left-right direction. Therefore, the rear left and right pressure-reducing wheel 73 only moves up and down, and the pressure-repressed position of the left and right pressure-reduced wheel 73 can be moved and adjusted left and right.

  A rear end portion of each pressure suppression arm 75 is formed in a gate-shaped rear frame 75f in a rear view, and the pair of left and right pressure suppression wheels 73 are disposed on both left and right sides of the rear frame 75f, and can be rotated by a support shaft 73a. I support it. The rear frame 75f is configured to be able to move in the forward direction across the upper part of the seedling planted in the ridge U. Further, a plurality of balance weights 75h are fitted and supported by a weight mounting arm 75g provided upward from the rear frame 75f, and the pressure reduction pressure can be adjusted by changing the number of the balance weights 75h.

  Stopper arms 75i are fixed to both the left and right sides of the slide boss 75d. The stopper arms 75i extend below the pivot base end 75a toward the rear of the machine body, and the leading end thereof is the pivot base end 75a. In this configuration, the pressure-reducing arm 75 is prevented from moving downward more than a predetermined amount by contacting the lower side of the U-shaped rear part. That is, the pressure-reducing arm 75 is rotated up and down from the position where the lower side of the rotation base end portion 75a contacts the stopper arm 75i, and the left-right pressure-reducing wheel 73 moves up and down.

  A lifting arm 74d that rotates integrally is provided at the right end portion of the pressure-reducing arm shaft 74c, and a right-turning cylinder portion 16b that is a part of a mechanism for moving the left and right rear wheels 7 up and down (by extending and retracting the rolling cylinder 11). The right arm 16a provided on the non-rotating side) is linked to the forced raising rod 76. The connecting portion between the front end of the forcibly rising rod 76 and the right arm 16a is provided with an interchangeable portion 76a formed of a long hole at the front end of the forcibly rising rod 76, and a pin having a base fixed to the right arm 16a. 76b is connected, and when the right rear wheel 7 is moved up and down by the lifting control during normal seedling transplanting, the forcible ascending rod 76 is not pushed and pulled, and the left and right rear wheels 7 are largely moved down when the aircraft is turning. Only when the forcible ascending rod 76 is pushed, the lifting arm 74d rotates in the direction of the arrow A, and the pressure-reducing arm shaft 74c rotates in the direction of the arrow A. The stopper arm 75i of the slide boss 75d also rotates in the direction of arrow A, and the left and right pressure-reducing arms 75 are rotated in the upward movement direction by the stopper arm 75i, so that the left and right pressure-reducing wheels 73 are automatically raised upward. It is configured to be housed rotated. Accordingly, when the left and right rear wheels 7 are moved downward during the turning operation of the aircraft at the end position of the heel U or when the aircraft is moved, the left and right pressure reducing wheels 73 are automatically housed and rotated upward. Can be turned and moved easily and workability is good.

  In addition, the mechanism for retracting and rotating the left and right pressure reducing wheels 73 is linked to the rear wheel 7 on the side that does not move up and down by the expansion and contraction operation of the rolling cylinder 11, so that it is appropriately affected without being affected by the expansion and contraction operation of the rolling cylinder 11. The left and right pressing wheels 73 can be stored upward.

  On the other hand, a stand support arm 74e is extended from the pressure-reducing frame 74a toward the lower side of the machine body to support the parking stand 77a. In the parking stand 77a, the tip of the left and right support rod 77d is fixed by welding to the grounding rod 77c provided at the tip, and a long hole 77e provided in the base of the left and right support rod 77d is provided between the left and right stand support portions 77b. The parking stand 77a is provided so as to be rotatable around the rotation shaft 77f. A parking notch groove 77g is provided at a position below the left and right stand support portions 77b, and a storing notch groove 77h is provided at a rear position. The parking hole 77e is provided on the tip side of the long hole 77e provided above the parking stand 77a. A fixing shaft 77i that hooks into the cutout groove 77g and the storage cutout groove 77h is provided, and a tension spring 77k is provided between the spring receiving shaft 77j provided above the rotation shaft 77f and the fixing shaft 77i. The fixing shaft 77i can be maintained in a state where it is caught by the parking cutout groove 77g and the storage cutout groove 77h by the tensile force of the tension spring 77k.

  When the fixing shaft 77i is hooked in the parking cutout groove 77g, the tip of the parking stand 77a is directed downward of the machine body, and the grounding rod 77c is grounded to support the machine body. In this parking state, the tread adjustment of the left and right rear wheels 7 can be easily performed by operating the planting operation lever 88 to operate the lifting hydraulic cylinder 14 to raise the left and right rear wheels 7 to a position where they are not grounded. . Also, when the aircraft is placed on a truck bed or the like and moved, if the parking stand 77a is parked, the hydraulic pressure of the elevating hydraulic cylinder 14 is released and the left and right rear wheels 7 are moved stably. The aircraft can be supported by the parking stand 77a.

  Next, until the fixing shaft 77i is disengaged from the parking notch groove 77g, it is pulled by holding the parking stand 77a against the pulling force of the pulling spring 77k, turning it upward and releasing it, and the pulling spring 77k. The fixing shaft 77i is hooked in the storage notch groove 77h by the pulling force, and the parking stand 77a is stored in the storage state above the fuselage. In this stored state, since the parking stand 77a is stored above the machine body, a favorable transplanting operation can be performed without interfering with the transplanting operation.

Accordingly, switching between the parking state and the storage state of the parking stand 77a can be easily performed with one touch, and the workability is good.
The left and right pressure-reducing arms 75 each provided with left and right pressure-reducing wheels 73 at the rear are provided with rod-shaped left and right indicators 78 that extend upward. Here, the configuration and operation of the left / right indicator 78 will be described.

A structure in which the lower end base of the left and right indicator 78 is rotatably supported by the support pin 75j at the rear end of the left and right pressure-reducing arm 75 by attaching the split pin 78c to the through hole provided at the upper end of the support pin 75j. It has become.

  Further, the reinforcing frame 92 in which the frame portion of the seedling supply device 24 is connected to the body frame 20 is provided with an upper guide support 92b and a left / right indicator 78 provided with circular through holes 92a for guiding and supporting the middle portions of the left and right indicators 78, respectively. A lower guide support 92d provided with a long through hole 92c that is long in the longitudinal direction of the machine body, which guides and supports the middle portions, is fixed.

  The left and right circular through holes 92a of the upper guide support 92b are disposed at the same position in the left and right direction of the machine body as the left and right elongated through holes 92c of the lower guide support 92d, and the left through holes 92a and 92c. The right through-holes 92a and 92c are provided at the same distance in the left-right direction from the left-right center of the machine body. The middle part of the left and right indicator 78 is disposed through the left and right circular through holes 92a of the upper guide support 92b and the left and right elongated holes 92c of the lower guide support 92d. When the wheel 73 moves up and down and the left and right suppression arm 75 moves up and down, the left and right indicator 78 moves up and down while staying parallel in the front view, and the operator moves the left and right indicators 78 left and right. The difference in height is very easy to see.

  In addition, since the base portion obtained by bending the lower end portion of the left / right indicator 78 into an L shape is configured to be rotatably supported by the support pin 75j at the rear end portion of the left / right pressure suppression arm 75, the left / right pressure suppression arm 75 is When adjusting the striations by adjusting the left / right position and changing the left / right position of the left and right pressure-reducing wheel 73, the base portion obtained by bending the lower end of the left / right indicator 78 into an L shape in accordance with the striation adjustment is a support pin 75j. Therefore, the left and right indicators 78 are kept parallel to each other when viewed from the front, and the difference between the left and right heights of the left and right indicators 78 is very easy to see regardless of the adjustment of the spacing.

In addition, a conspicuous color (for example, yellow) marker 78d serving as an index is attached to the upper end of the left / right indicator 78.
Therefore, when the pressure-reducing wheel 73 moves up and down following the heel U surface during the transplanting operation, the left and right pressure-reducing arms 75 provided with the pressure-reducing wheels 73 that repress the left and right planting positions respectively move up and down. The markers 78d of the left and right indicators 78 also move up and down in conjunction with the up and down movement of 75. That is, when the right side of the upper surface of the heel U is high and the left side is inclined low when facing the advancing direction of the aircraft, the marker 78d of the right indicator 78 is positioned higher than the marker 78d of the left indicator 78. The person can immediately recognize that the right side of the upper surface of the bag U is high and the left side is inclined low.

  Therefore, when the operator is seated on the seat 79 and performing the transplanting operation, the operator immediately recognizes the right / left inclination of the heel U by looking at the marker 78d of the left / right indicator 78 and the difference in the height of the left / right marker 78d. Therefore, the body can be adjusted so that the height of the marker 78d of the left and right indicator 78 is the same by operating the rolling control valve B2 by operating the manual body tilt adjustment lever 15 in the left and right direction of the body and expanding and contracting the rolling cylinder 11. Tilt. Then, since the body is parallel to the inclination of the ridge U, the planting depth of the seedlings by the left and right seedling planting bodies 5 at the left and right planting positions becomes the same, and an appropriate seedling transplanting operation can be performed.

  In addition, support pins 75j provided on the inner side of the body of the weight mounting arm 75g located at the center of the left and right on the gate-shaped rear frame 75f of the rear end portion of the left and right suppression arms 75 are provided respectively. Since the bottom end of the left and right indicator 78 is supported by the support pin 75j and the left and right indicator 78 is provided in parallel when viewed from the front of the body, the left and right marker 78d of the left and right indicator 78 is close to the left and right. The difference in height is easy to understand, and the tilting operation of the aircraft can be performed accurately and easily, and the workability is good.

  Furthermore, an inclination indicator 120 that rotates to the left and right according to the difference in height of the left and right markers 78d and an inclination scale plate 121 that includes an angle scale 121b for determining the inclination angle are provided, and the inclination state of the heel U or the aircraft is provided. It is good also as a structure which can judge easily. The inclination indicator 120 is a plate body provided with a vertically long hole 120a that is long in the vertical direction. A tilt indicator fulcrum shaft 122 provided on the machine body side is inserted into the vertical slot 120a. Further, the upper end portion of the tilt indicator 120 and the left and right markers 78d are connected by the left and right connecting wires 123, respectively. In addition, the inclination indicator fulcrum shaft 122 is disposed at the left and right center position between the left and right indicators 78, and the left and right connecting wires 123 are set to the same length. Accordingly, with the difference in height between the left and right markers 78d, the tilt indicator 120 rotates in the left-right direction about the tilt indicator fulcrum shaft 122 via the connecting wire 123. The left and right connecting wires 123 are inclined to the left and right where the left and right markers 78d are higher than the inclination indicator 120 side over the vertical movement range of the pressure reducing wheel 73. The tilt scale plate 121 is a fan-shaped (semi-circular) plate centered on the tilt indicator fulcrum shaft 122 and is fixed to the machine body at a position below the tilt indicator fulcrum shaft 122. A plurality of angle scales 121b are provided in the normal direction centered on the shaft 122, and a plurality of arc-shaped height scales 121a are provided in the circumferential direction centered on the tilt indicator fulcrum shaft 122. Each of the height scales 121a is an arc having different radii around the tilt indicator fulcrum shaft 122. Therefore, with the difference in height between the left and right markers 78d, the tilt indicator 120 rotates in the left-right direction, and an operator who is seated on the seat 79 is instructed by the indicator 120b provided at the lower end of the tilt indicator 120. The inclination state can be recognized by visually recognizing the angle scale 121b. Further, along with the average height change of the left and right markers 78d, the tilt indicator 120 is moved up and down guided by the vertical slot 120a, and the operator moves the height scale 121a indicated by the indication index 120b. By visually recognizing the height of the machine body relative to the field scene, the seedling planting depth of the seedling planting device 23 (average seedling planting depth by the right and left seedling planting devices 23) can be recognized. Therefore, by visually recognizing a common recognition device, the inclination angle and height (planting depth) can be recognized, and the operator can easily recognize these.

  In addition, a rear seat 79 is provided above the bonnet Bo that covers the upper part of the engine 3 and the transmission case 8 so as to face the seedling supply device 24 side, and a flat step 80 for placing a foot between the seedling supply device 24 is provided. ing. The seat 79 is supported by the airframe via a support frame 81 that extends upward through one of the left and right sides (right side) of the bonnet Bo.

  The step 80 includes a main step 82 disposed between the seat 79 and the seedling supply device 24 in plan view of the machine body, and sub-steps 83 provided on both the left and right sides of the seat 79 and the bonnet Bo. The sub-step 83 extends forward and backward from the front end portion of the aircraft to near the main step 82, the front portion 83a is configured to be one step lower than the rear portion 83b, and an operator can get on and off from the front end portion of the aircraft. It has become. An elevating mechanism (arm 16a, rolling cylinder 11, rod 13, etc.) for raising and lowering the rear wheel 7 can be disposed below the rear portion 83b which is the upper stage of the sub-step 83, and the aircraft body can be used effectively by utilizing the space of the aircraft body. We are trying to make it more compact. Further, a transmission case 9 that rotates up and down can be disposed below the rear portion of the sub-step 83 in accordance with the tread change of the rear wheel 7. In addition, a rising portion 82a is provided at the front end of the main step 82 so as to be inclined upward and the operator's foot sitting on the seat 79 contacts the vertical movement mechanism 4 of the seedling planting device 23 by the rising portion 82a. It is protected as a configuration that does not. Further, by positioning the rising portion 82a below the seedling supply device 24, the longitudinal length of the machine body can be shortened. Moreover, the main step 82 is provided with the rising portion 82a, whereby the strength is improved. The rising portion 82 a includes a main clutch lever 84 for turning on and off the left and right rear wheels 7, the seedling planting device 23 and the seedling supply device 24, and a left and right side brake pedal 85 for braking the left and right rear wheels 7. The operator in the seat 79 can stop the aircraft and correct the traveling direction of the aircraft.

  At the front end of the fuselage between the left and right front wheels 6, there is provided a heel end sensor 86 for grounding the top surface of the heel U to detect the end of the heel U, and the heel end sensor 86 is free from wrinkles due to the advance of the body. It is configured to detect that the end of the bag has been reached by losing the sense of the upper surface of the bag after reaching. Based on the detection of the heel end by the heel end sensor 86, the main clutch is automatically disengaged to stop the driving of the left and right rear wheels 7, the driving of the seedling planting device 23 and the seedling supplying device 24, and the machine body is stopped. At the same time, an alarm (for example, a buzzer or the like) is issued to notify the worker. As a result, the operator sitting in the seat 79 faces backward in the direction of travel of the aircraft and concentrates on seedling replenishment work, so it is difficult to confirm the front of the aircraft and does not notice that the aircraft has reached the end of the heel. There is a risk of accidents such as a collision with the structure of the vehicle. However, since the aircraft end sensor 86 automatically stops the aircraft at the end of the vehicle and notifies the end of the vehicle by an alarm, In addition, it is possible to concentrate the seedling replenishment work to the seedling supply device 24 without worrying about the situation in front of the machine body and the position of the end of the cocoon, thereby improving the planting work efficiency. The heel end sensor 86 is disposed at a position to the right of the left and right center of the aircraft, and the influence of the vertical movement of the aircraft due to the vertical movement of the left rear wheel 7 by the rolling cylinder 11 is small. The top surface of the cocoon can be detected.

  As the warning means, a configuration in which a warning lamp that is lit or blinking is provided in front of the linear portion 38 on the front side in the circulation locus of the seedling supply cup 25 of the seedling supply device 24 or inside the circulation locus is adopted. May be. This warning lamp is configured to be long along the circumference trajectory of the seedling supply cup 25, and it is easy for an operator who sits on the seat 79 and performs the seedling replenishment work to the seedling supply cup 25 to reach the end of the heel. Can be recognized.

  Further, as another alarm means, a configuration in which a vibration device that vibrates the seat 79 may be employed. The vibration device is provided below the seat 79 and is configured such that an eccentric cam that rotates by driving of a vibration motor hits the seat 79 and vibrates the seat 79 up and down. Thereby, the operator who sits on the seat 79 and performs the seedling replenishment work to the seedling supply cup 25 can easily recognize that the machine body has reached the end of the heel.

  It should be noted that when planting in a flat field where no cocoons are formed, it is impossible to detect by the heel end sensor 86 that the machine has reached the end of the field, so the machine reaches the end of the field 1 What is necessary is just to set it as the structure which recognizes that the body reached | attained the edge of the field based on the planting travel distance or planting stock number for a stroke. Specifically, the set planting travel distance or set planting stock number for one stroke is input to the control device in advance, and the control device sets the engine 3 rotation speed or the wheel (front wheel 6 or rear wheel 7) rotation speed. The actual planting travel distance is determined by detection with the rotation speed sensor, or the operation of the seedling planting device 23 (for example, the vertical movement mechanism 4) is detected by the planting count sensor to determine the actual planting strain number. An alarm is issued when the planting mileage or the actual planting stock reaches the set planting mileage or the set planting stock. The actual planting travel distance may be calculated by multiplying the number of planted plants detected by the planting count sensor and the inter-plant setting set by the operator using the inter-plant setting lever. Good.

  Also, near the steering handle 2, there are a main clutch lever 87 for manually turning on and off the left and right rear wheels 7, the seedling planting device 23 and the seedling feeding device 24, a seedling planting device 28 and a seedling feeding device 32. And a planting operation lever 88 for manually turning on and off only the drive. The planting operation lever 88 can be used to operate the lifting hydraulic cylinder 14 to manually lift and lower the machine body. Then, a sensor (detection means) for detecting the operation position of the planting operation lever 88 is provided, and only when the seedling planting device 23 and the seedling supply device 24 are operated in the drive state by the planting operation lever 88, It is configured such that the automatic stop control and alarm of the airframe are activated by the aforementioned heel end sensor 86. As a result, the automatic stop control and alarm of the aircraft can be activated only during planting work, and the aircraft endless sensor 86 is unnecessarily detected because the heel end sensor 86 does not detect the upper surface of the heel when traveling or turning at the heel end. Can be prevented and the operability is improved. A seating sensor for detecting that an operator is seated on the seat 79 is provided in place of or in combination with the above-described automatic stop control of the aircraft by the planting operation lever 88 and on / off of the alarm operation. It is good also as a structure which the automatic stop control and alarm of a body operate | move only when the operator is sitting. Moreover, it can be set as the structure which a warning is act | operated first by the detection of the end of the hull by the hail end sensor 56, and the body stops automatically after the predetermined time (several seconds later). The airframe may be automatically stopped by stopping the engine 3.

  Further, when the planting operation lever 88 is operated to raise the machine body and turn on the heel, when the heel end sensor 86 is moved up and stored, the heel end sensor 86 is not in the way of turning. It can be turned easily.

  The heel end sensor 86 has a configuration in which a rotation roller 86b is rotatably provided at the lower end of a rotation arm 86a pivotally supported on the base of the machine body. A lower rotation restricting rod is provided at a position below the rotation arm 86a so that the rod end sensor 86 (rotating roller 86b) does not rotate downward more than necessary. When the planting operation lever 88 is operated so as to raise the machine body, the downward rotation restricting rod is moved upward via the operation wire so that the attachment operation lever 88 is linked with the operation wire. The rotating arm 86a is rotated upward to the storage position by contact.

  Left and right seedling platforms 89 are arranged on the left and right sides of the machine body. The left and right seedling mounting platforms 89 have three upper seedling mounting portions 101a, 101b, and lower seedlings on the inner side of the body above the seedling support frame 100, the base of which is rotatably and fixedly provided on the body. A mounting portion 101c is provided.

  In addition, a boarding platform 124 on which a walking worker rides in a standing posture can be mounted behind the left and right rear wheels 7. At the front end and the rear end of the boarding platform 124, a rotatable support wheel 125 that is grounded is provided. A platform traction arm 126 is connected between the support wheel axle serving as the axle of the front support wheel 125 and the rear wheel axle 10, and the platform traction arm 126 follows the farm field and centers on the rear wheel axle 10. It is configured to rotate up and down. Between the boarding platform pulling arm 126 and the boarding board 124, a torque type (torsion type) accommodation spring for accommodating the boarding platform 124 is provided. Therefore, when the operator does not board the boarding platform 124, the boarding platform 124 and the rear support wheel 125 rotate upward about the front support wheel axle by the storage spring, and the rear support wheel 125 It rotates to the position which contacts the outer peripheral surface of the rear wheel 7, and the boarding board 124 and the rear support wheel 125 are comprised. When an operator boardes the boarding platform 124, the boarding platform 124 is deployed against the storage spring, and the rear support wheel 125 is grounded by the weight of the operator. Therefore, when the operator does not board the boarding platform 124, the boarding platform 124 and the rear support wheel 125 are automatically stored, and the operator can easily turn the aircraft by the steering handle 2 at the end of the field. . Further, since the rear support wheel 125 comes into contact with the outer peripheral surface of the rear wheel 7 in the stored state, the dirt or the like adhering to the outer peripheral surface of the rear wheel 7 can be dropped by the rear support wheel 125.

  As described above, the transplanter (1) rotates the pair of planted body parts (5L, 5R) that accommodates the planted material inside to open and close the lower part to plant the planted product in the field. The planting body (5) and a vertical movement mechanism (4) for moving the planting body (5) up and down between a position where the lower end of the planting body (5) is above the farm scene and a position below the farm scene. ), A cutting blade (113) for cutting the multi-film laid on the field is provided on the outer surface of the planted body portion (5L, 5R), and the outer edge of the cutting blade (113) In the state where the lower part of the planted body (5) is closed, the lower side is located on the planted body side or along the vertical direction or the substantially vertical direction, and when the upper part of the planted body (5) is opened, the lower side is planted. Provided with a gentle slope (114) located on the side away from the body There.

  Therefore, when the planting body (5) moves downward with the lower part closed, the gently inclined part (114) of the outer edge of the cutting blade (113) does not incline or the inclination of the gently inclined part (114) is moderate. Therefore, the downward movement resistance by the gently inclined portion (114) is reduced, and the planted body (5) can smoothly enter the soil by the downward movement of the planted body (5). And when the lower part of the planting body (5) is opened or when the planting body (5) is moved upward, the multi-film is gradually cut by the gently inclined portion (114) of the outer edge of the cutting blade (113). The multi-film can be cut smoothly, and as a result, a desired planting hole can be formed in the multi-film, so that the cultivation after transplanting can be performed well.

  Further, the outer edge of the cutting blade (113) is positioned below the gentle slope portion (114) and closer to the planting body (5), regardless of the open / closed state of the lower part of the planting body (5). The planted body (5) is provided with a plunging part (115) that plunges into the soil.

  Therefore, since the slope of the ridge portion (115) at the outer edge of the cutting blade (113) is steeper than the slope of the gentle slope portion (114), the planted body (5) is lowered with the lower portion closed. When moving and plunging into the soil, the piercing part (115) can surely form an opening hole in the multi-film, and the above-mentioned gradual inclined part (114) accurately cuts the aforementioned multi-film. The multi-film can be cut smoothly, and as a result, a desired planting hole can be formed in the multi-film, so that the cultivation after transplanting can be performed well.
