Therefore, conventionally, in order to form a planting groove with a grooving machine in the field, when multi-cultivation, the multi-film will be cut with a grooving machine, so a conventional planting disk I couldn't plant seedlings.
Then, in order to make it applicable also to multi cultivation, it is possible to plant using the planting cup which moves up and down. However, in this case, it is necessary to smoothly change the posture of the seedling conveyed in a horizontal posture by the seedling conveying belt to a vertical posture with the root portion facing downward and supply the seedling cup to the planting cup.

For example, if the seedling to be planted is a pot seedling, a root (root pot) is attached to one end of the seedling, and if this collapses during delivery to the planting cup, a hole is made in the soil with the planting cup when planting. When the planting cup was opened and then the planting cup was raised, the seedling was not heavy enough, so the seedling was lifted together with the planting cup due to the resistance of the seedling, making it difficult to plant well.
In view of the above problems, the present invention smoothly changes the posture from a horizontal posture to a vertical posture in which the root portion is directed downward so that the root portion is not destroyed when the seedling is transferred from the seedling conveyance belt to the planting cup. However, seedlings can be delivered to the planting cup.

The technical means of the present invention for solving this technical problem is a transplanting machine in which seedlings transported in a horizontal posture by a seedling transporting belt are planted by changing the posture into a vertical posture in which the root part is downward,

Further, the receiving member 67 is disposed at substantially the same height as the upper surface of the conveyor belt 45, and the receiving member 67 has a stem and leaf portion Nb of the pot seedling N before the seedling N reaches the pair of seedling clamping rollers 59. It is designed to receive the tip side.

The receiving member 67 is provided with an inclined guide portion 68 that gradually descends toward the root Na side of the seedling N. By the inclined guide portion 68, the foliage Nb of the seedling N is gradually increased toward the root Na side. It is received in an inclined state that greatly descends. The lower end of the inclined guide portion 68 of the receiving member 67 is disposed so as to be close to the central portion of the pair of seedling sandwiching rollers 59 in the axial direction.
As shown in FIGS. 7 and 8, the receiving member 67 is provided with a closing sheet 71 made of elastic synthetic resin or the like. One end of the closing sheet 71 is fixed to the lower surface of the receiving member 67 by adhesion or the like, and the other end side of the closing sheet 71 is elastically deformed upward. The closing sheet 71 closes the space between the receiving member 67 and the end portion of the conveyor belt 45. Two closing sheets 71 are provided on the rear side (horizontal portion) and the front side (inclined guide part 68 side) of the receiving member 67, and these closing sheets 71 are substantially the entire length of the receiving member 67 in the front-rear direction. It is over.

  Below the pair of seedling sandwiching rollers 59, a guide tube 73 is provided fixed to a frame or the like on the machine body side of the transplanter 1. The guide tube 73 is formed in a tapered square tube shape in which the lower side is gradually narrowed. The seedling N falling from between the pair of seedling sandwiching rollers 59 is guided through the cylindrical body of the guide cylinder 73 to the lower planting cup 19. The guide cylinder 73 is disposed between the pair of seedling sandwiching rollers 59 and the planting cup 19, and the seedling N dropped from the seedling sandwiching roller 59 passes through the cylindrical body of the guide cylinder 73 and is delivered to the planting cup 19. The timing (position) is set when the planting cup 19 moves downward beyond the top dead center of the vertical movement (position).

As shown in FIGS. 3, 6, and 7, the push-down means 62 is provided on the side of the planting transmission case 40 and corresponds to the front end of the shutter 60 (the root Na side of the seedling N). The root push rod 75 and the support arm 76 to which the root push rod 75 is attached are provided, and the root push rod 75 is attached to the rear end side of the support arm 76.
The front end of the support arm 76 is supported by the frame of the transplanter 3 so as to be rotatable about a support shaft 77 in the left-right direction so that it can swing up and down. The other end of the link 78 is pivotally connected to the left and right axial centers, and the other end of the link 78 is a left and right output shaft provided on the upper side of the front side of the planting transmission case 40. 79 is pivotally connected via a pin 81 in the left-right direction at a position deviating from the rotation center of the rotating body 80 that is rotationally driven by 79, and the support arm 76 swings up and down by the rotation of the rotating body 80, The root push rod 75 is configured to move up and down (the root push rod 75 is intermittently reciprocated vertically).

The root push rod 75 is moved downward by pressing a root Na of the seedling N held between the shutter 60 and the terminal end side of the conveyor belt 45 to open the shutter 60 while pressing the root Na from the pair of seedling sandwiching rollers 59. Also move down.
According to the embodiment, the seedling N is intermittently conveyed toward the end side by the conveying belt 45 sequentially, and the shutter 60 inclined forward and downward toward the conveying belt 45 and the end of the conveying belt 45 are arranged. In the meantime, the seedlings N are sequentially held one by one. At this time, as indicated by a chain line A in FIG. 9, the tip end side of the foliage Nb of the seedling N is placed on the receiving member 67 and the seedling N is held in an inclined state in which the root (Na) side is lowered.

  The root portion Na of the seedling N held between the shutter 60 and the conveyor belt 45 is pressed downward by the root portion push rod 75 and moves below the pair of seedling sandwiching rollers 59. At this time, the shutter 60 opens. As a result, the seedling N falls from the shutter 60, and the tip end side of the stem and leaf portion Na of the seedling N is placed in an inclined state on the inclined guide portion 68 of the receiving member 67 as shown by a chain line B in FIG. The base end side of Nb enters between the pair of seedling sandwiching rollers 59, and is sandwiched between the pair of seedling sandwiching rollers 59. The seedling N changes its posture from a horizontal posture to a vertical posture in which the root Na is downward, The stem and leaf portion Nb is sandwiched, and the seedling N is moved downward in a vertical posture with the root portion Na downward as the pair of seedling sandwiching rollers 59 rotates, and falls into the planting cup 19 moving upward, This Cup 19 receives a seedling N from a pair of seedling clamping rollers 59 on the upper side of the transfer zone.

The planting cup 19 that has received the seedling N descends and is inserted into the cocoon, and opens below the moving area to release and release the seedling N, thereby opening the planting hole in the field and moving the upper side of the moving area. The seedlings N received in step 1 are planted in the field below the moving area.
Thereafter, the planting cup 19 moves upward, and the planting cup 19 closes in conjunction with the lifting operation.
During this time, the next seedling N is held between the shutter 60 and the conveyor belt 45, and the seedling N has the stem and leaf portion Nb of the seedling N while changing its posture from a horizontal posture to a vertical posture in which the root Na is downward. With the rotation of the pair of seedling sandwiching rollers 59, the seedling N is moved downward in a vertical posture with the root Na facing downward, and dropped again into the planting cup 19 that has moved upward. The seedling N is received from the pair of seedling sandwiching rollers 59 on the upper side.

Thereafter, the same operation is intermittently repeated.
Therefore, in the seedling supply device 21 having the above-described configuration, when the seedling N is delivered from the transport belt 45 to the planting cup 19, the root portion Na of the seedling N is forcibly pushed by the root push rod 75, and a pair of seedlings is thus obtained. The stems and leaves Nb of the seedling N can be bitten between the pinching rollers 59, and the seedling N can be supplied to the planting cup 19 without mistake, and the root Na is directed downward from the horizontal posture so that the root Na is not destroyed. The seedling N can be delivered to the planting cup 19 while smoothly changing the posture to the vertical posture.

In addition, since the blocking sheet 71 covers the entire length between the conveyance belt 45 and the receiving member 67, it is possible to prevent the dead leaves of the seedling N from being sandwiched between the conveyance belt 45 and the receiving member 67. It is possible to prevent an erroneous delivery of the seedling N to the planting cup 19 due to pinching of dead leaves or the like.
Further, when the seedling N is thin and the foliage portion Nb is easy to bend, when changing the posture from the horizontal posture to the vertical posture, the foliage portion Nb may be bent greatly, making it impossible to smoothly change the posture. Before N reaches the pair of seedling sandwiching rollers 59, the slant guide portion 68 of the receiving member 67 receives the tip side of the foliage portion Nb of the seedling N, so that even if the seedling N is thin and the foliage portion Nb is easy to bend, By the guide portion 68, the foliage portion Nb of the seedling N can be stably received in an inclined state in which it gradually descends gradually toward the root portion Na side, and between the shutter 60 and the end side of the conveyor belt 45. Even in the held standby state, it is possible to wait in an inclined state where it gradually descends toward the root Na side, so that the seedlings N conveyed in a horizontal posture are in a vertical posture with the root Na downward. Can be smoothly attitude change, it is possible to improve the transfer accuracy of the planting cup 19 seedlings N. In addition, since the tip of the descending side of the inclined guide portion 68 of the receiving member 67 is disposed so as to be close to the axial central portion of the pair of seedling sandwiching rollers 59, the seedling N is located with respect to the seedling sandwiching roller 59. Even if it is considerably displaced in the front-rear direction, the foliage Nb of the seedling N is securely clamped between the seedling clamping rollers 59, and the seedling N is changed to the vertical posture and smoothly received by the planting cup 19 side. Can pass.

Further, by rotating the pair of seedling sandwiching rollers 59 at a high speed, the planting speed can be made sufficiently high, and the seedling N transported in a horizontal posture by the transport belt 45 is smoothly placed in a vertical posture with the root Na facing downward. It can be changed and good planting can be done at high speed.
Also, if the guide tube 73 is moved up and down integrally with the planting cup 19, the seedling N falls from the seedling pinching roller 59 toward the guide tube 73 when the guide tube 73 rises, and the The root Na collides with the inner wall surface (for example, the front inner surface) of the guide tube 73, whereby a timing delay occurs, and the seedling N can be reliably held at the distal end portion (lower end opening portion) of the planting cup 19. Therefore, there arises a problem that the seedling N is supplied to the tip of the planting cup 19 with a slight delay. However, in the case of the present embodiment, since the guide tube 73 is fixed to the frame or the like on the machine body side of the transplanter 1, the guide tube 73 can be made to correspond accurately below the pair of seedling sandwiching rollers 59. The falling seedling N does not hit the inner surface of the guide tube 73 strongly, so that the seedling N can be smoothly supplied to the planting cup 19 and can be adapted to high-speed planting of the seedling N.

And since the seedling N is planted using the planting cup 19 which moves up and down, even when laying a multi film on a cocoon, it does not cut a multi film and is suitable for multi cultivation.
In the present embodiment, the pot seedling N is planted, but the seedling to be planted is not limited to the pot seedling N, and may be a root washing seedling or other seedlings.
