BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter which takes out vegetable seedlings, such as onions, from a seedling tray and plantes them in a field, and relates to a transplanter which is used well in vegetable seedlings having a relatively narrow line spacing.

Usually, one seedling loading stand is provided with a set of transplanting mechanisms, and one seedling for each row is taken out by one seedling take-up hook from one seedling tray, and the seedling transplant hooks are picked up, followed by transplantation. This has been done. For this reason, in a walk-type implanter having only one seedling loading stand, only one line is transplanted in one stroke, for example, when a large number of lines are transplanted on one head, the stroke according to the number of lines It is necessary to carry out work. Thus, there are two rows of transplanting means having two left and right seedling extracting hooks and seedling transplant hooks which simultaneously take out two seedlings from one seedling tray and carry out two rows of transplants. Since the gap width of the left and right seedling extraction hooks and the width of the left and right seedling transplant hooks corresponding to the planting line (for example, the gap width of the seedling transplant hooks about 200 mm for the 142 mm gap of the seedling extraction hooks), In the position where the seedlings of the hook and seedling transplant are inherited, the center of the seedling extraction hook and the center of the seedling transplant hook are offset (approximately 29 mm in the above-described example), so that the seedlings are removed from the seedling extraction hook. There was a problem that proper seedlings were not exchanged with the graft hook.
Therefore, the present invention in the seedling transplanting device of the transplanter to receive the seedlings taken from the seedling tray of the seedling loading rack by a pair of left and right seedling take-out hooks, followed by a pair of left and right seedling transplant hooks, the seedlings of the left and right seedling transplant hooks The width of the left and right gaps at the receiving position is reduced, and the width of the left and right gaps at the position where the seedlings are planted is increased. In addition to this, the proper planting is planting seedlings with proper posture between the lines to improve the precision of transplantation.
In addition, by installing the left and right graft hook drive mechanism for driving the left and right seedling transplant hooks in an inclined shape, special mechanisms are unnecessary, and as a simple and economical construction means by simply tilting the existing graft drive mechanism. It is to improve porting precision.
In addition, by placing the implantation motor case between the left and right transplant hook drive mechanism, by connecting the output shaft of the implanted transmission case to the input shaft of the implanted hook drive mechanism through the universal joint, the implanted hook drive mechanism by a simple means of universal joint only This is connected to a transplantation transfer case, which economically improves the transplant accuracy.

The left and right rotary input shafts 33 and 33 are connected to each other via the chain 41 at the ends of the output shafts 39 and 40 of the implanted clutch case 38 which connects the input shaft 37 to the mission case 9. Extraction of two left and right seedlings at the time of connection of the implantation clutch 38a of the implantation clutch case 38 The rings 23 and 23 are driven in the same phase to simultaneously take out two rows of port seedlings N from one seedling tray 22, and then descend to the position where the hooks 23 and 23 are picked up. It is configured to move to.

Further, the seedling gripping hook 25 is provided with a rotary case 44, a crank arm 45, and both ends of an output shaft 43 of a single transmission case 19 that interlocks and connects the input shaft 42 to the mission case 9. It is to install the left and right seedling transplant hooks (25) symmetrically through each of the implantation arms (46), rotate the rotary case (44) about the output shaft (43), and lift the guide rails through the crank arms (45). The transplant arm 46 is moved up and down while swinging back and forth along the 47 so as to vertically move the transplant hook 25 into an oval-shaped implant trajectory, and at the same time, open and close two semi-conical hooks 25a and 25b. When the transplant hook 25 is formed in one rotation of the rotary case 44, the seedling N is received from the ejection hook 23, and the transplant hook 25 is formed. Cam 48 and crank arm of crank arm 45 when By the cam action of the rod 49 of the arm 46, the hook bodies 25a and 25b are opened and closed to form openings in the bump surface M, and the hook bodies 25a and 25b. ) It is comprised so that the inside seedling N may fall to the opening of the hollow surface M. FIG.

In addition, the seedling loading table 21 is supported by the guide rail 51 and the horizontal feed drive shaft 52 between the left and right side frame 50 fixed to the chassis frame 17 so as to be reciprocated left and right, and seedling loading Longitudinal feed chain that is provided in tension between the drive sprocket 54 supported by the vertical feed drive shaft 53 on the base 21 and the dielectric sprocket 56 supported by the dielectric shaft 55 ( The vertical feed pins 57a for each predetermined interval of 57 are coupled between the bottom portions of the pots of the seedling tray 22, so that when the seedling loading table 21 reaches the left and right moving ends, the vertical feed shaft 58 The seedling tray 22 is vertically conveyed by one pitch via the vertical feed cam 59.

By the way, as shown in FIG. 8 and FIG. 9, the rotary case 44 and the crank arm 45 which drive the two left and right seedling grafts 25 and 25 and these two left and right hooks 25 and 25, respectively. ) And the left and right seedling transplanters 18a and 18b such as the transfer arm 46 are inclined in left and right symmetry in the left and right directions when viewed from the front and the rear, and the planetary gear 61 is mounted on the installation shaft 60 of the crank arm 45. ), The sun gear 63 of the rotary case 44 connected through the intermediate gear 62 is detachably inclined and fixed to the left and right flange bodies 64 and 65 of the electric case 19, and the safety clutch 66 is fixed. Inclining the installation shaft 68 of the rotary case 44 through a universal universal joint 67 at both ends of the output shaft 43 of the transmission case 19, which is held substantially horizontally in the transmission case 19. Fixed position, left and right through the sun gear 63 and the mounting shaft 68 on the left and right sides of the transmission case (19) Bore the seedling transplantation apparatus (18a, 18b) in front and back and reduce the width of the upper space, and further configured to connect to tilt at an angle (θ, θ ≒ 6 °) so as to increase the width of the lower interval.

Then, for example, the pitch of the ejection holes of the seedling tray 22 of 200 (10 × 20) holes or 288 (12 × 24) holes (5 in horizontal 10 and 6 in horizontal 12) ), The width of the gap between the left and right seedling transplant hooks 25 at the time of the uppermost movement of the left and right seedling transplant hooks 25 by matching the hook pitches T which are the distances between the centers of the ejection hooks 23 of the two left and right seedlings. To the hook pitch (T) to ensure the exchange of seedlings (N) from the seedling extraction hook (23) to the seedling hook (25), and the transplantation position of the left and right seedling transplant hooks (25). At the time of the lowest movement of the hook, the gap width between the left and right seedling transplant hooks 25 is widened between the transplant lines (W, W = 20 cm), and the seedlings (N) are transplanted between the appropriate lines.

Thus, as shown in Fig. 10, in the transplantation operation, two rows of transplants are performed simultaneously in one stroke transplantation operation, and after completion of the transplantation operation, the moving gas is turned to perform two rows of simultaneous transplantation in the second administration. Thus, seedlings of four rows of seedlings are carried out on one hungry surface M, and six rows or ones on one hungry surface M are carried out by sliding the moving gas between each two rows of left and right plants. You can also port many lines, including eight lines.

In addition, the total width of the seedling feeder 16 can be reduced by reducing the transverse feed amount of the seedling loading zone 21 by two rows of simultaneous transplantation, and between the rows of the transplanted seedlings N. Can always be uniformly aligned, and also the handle 26 can be easily operated at the worker position between the heads at the rear of the left rear wheel 8 even in the wide head. Therefore, this handle 26 operability can be improved.

Moreover, the interval width (hook pitch T) which takes the seedling of the left and right seedling extraction hooks 23 between graft lines W is small (T <W), and the center and seedling taking the seedlings of the seedling extraction hooks 23 Even in a transplantation structure in which the seedling transplant center of the transplant hook 25 is offset in the lateral direction (E), a separate seedling relay guide or the like is carried out between the seedling extraction hook 23 and the seedling transplant hook 25. It is not necessary to install the inheriting member, and the seedling (N) can be directly inherited directly from the seedling extraction hook (23) to the seedling hook (25), and the implantation precision can be improved by a compact structure. .

As can be seen from the above embodiment, the present invention is a pair of left and right seedlings taken from the seedling tray 22 of the seedling loading zone 21 by the left and right pairs of seedling extraction hooks 23. In the implanter to be transplanted following the transplant hook 25, the left and right gap width of the position to inherit the seedlings of the left and right seedling transplant 25, and also to increase the left and right gap width of the position to plant the seedlings, The two seedlings (N) for two rows taken out simultaneously from the seedling tray 22 of the seedling loading stand 21 by the take-out hook 23 are satisfactorily succeeded by the seedling-hooking 25, and an appropriate transplant line By transplanting seedlings (N) in the appropriate posture in between (W), the transplantation accuracy can be improved.

In addition, since the left and right transplantation mechanisms 18a and 18b for driving the left and right seedling transplanting hooks 25 are installed in an inclined shape, no special mechanism is required, and only the existing implantation mechanisms 18a and 18b are inclined. As a simple and economical means of construction, the implantation accuracy can be improved.

In addition, the transfer transmission case 19 is disposed between the left and right transplantation mechanisms 18a and 18b, and the output shaft 43 of the transplantation transmission case 19 is connected to the input shaft 68 of the implantation mechanisms 18a and 18b. Since it is interlocked through (67), by connecting the implantation mechanism (18a, 18b) to the drive transmission source 19 as a drive source by a simple means of universal joint only, the implantation accuracy can be improved economically.
