Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is provided with an empty box storage container for storing the pot seedling box at the tip of the guide frame of the pot seedling box, and automatically drops the empty pot seedling box out of the guide frame to the empty box storage container. It relates to the improvement of a pot seedling transplanter.
[0002]
[Prior art]
In a pot seedling transplanter, a flexible pot seedling box with many pot-shaped seedling chambers connected is inserted into an inclined seedling platform and fed one row at a time. The pot seedlings are taken out one row at a time, and the pot seedling box after taking out the pot seedlings is almost in the same direction as the entrance of the seedling stand along a curved guide frame so that the bottom surface side of the pot seedling box becomes a curved inner surface. To guide you. The pot seedling boxes that are completely emptied after all the pot seedlings are pushed out are generally extracted from the guide frame by the operator and stacked on a seedling box receiver installed on the machine body.
On the other hand, in Japanese Patent Application Laid-Open No. 11-243720, an empty box storage container is provided at the exit of a guide frame (expressed as a guide rod in the same publication) and pushed by a succeeding pot seedling box to be pushed out of the guide frame. It is described that the pot seedling box is dropped into the empty box storage container. In this case, since the empty pot seedling box is automatically collected, there is an advantage that the labor of the operator can be saved, and the supply of the pot seedling box and the operation of the transplanter can be concentrated accordingly.
[0003]
[Problems to be solved by the invention]
By the way, as shown in FIGS. 5A and 5B, the pot seedling box 1 that is generally used in such a transplanting machine is also described in the bottom part of the above-mentioned JP-A-11-243720. A pot-shaped seedling chamber 3 having a flexible opening (or crack) 2 into which an extrusion bar can be fitted is arranged in a grid pattern, and an edge having feed holes 4 for feeding this seedling box one pitch at a time to the left and right An ear portion (projection piece) 6 is formed on the left and right ends of the portion 5 and the front and rear portions thereof, and a protrusion 7 is formed on the side surface of the pot-shaped seedling room aligned with the front end and the rear end, so that the whole has flexibility. In addition, the ear | edge part 6 is for making it adapt to a seeding machine, and the protrusion 7 is for sending seedling boxes in a butt | matching state.
[0004]
When such a pot seedling box 1 is used in a transplanter equipped with an empty box storage container as described above, as shown in the above-mentioned Japanese Patent Application Laid-Open No. 11-243720, In FIG. 2, the ears at the rear end of the preceding pot seedling box and the ears at the front end of the succeeding pot seedling box are usually transferred in an overlapping manner. As shown in FIG. 6, if the overlapping ear portion 6 a at the rear end of the preceding pot seedling box 1 a is located below the front ear portion 6 b of the subsequent pot seedling box 1 b, When the pot seedling box 1a is pushed out of the guide frame 8 by the subsequent pot seedling box 1b, the pot seedling box 1a falls into the empty box container 9. However, if any one of the ears 6a at the rear end of the pot seedling box 1a is on the ear 6b at the front end of the succeeding pot seedling box 1b, the pot seedling box 1a is pulled to the ear 6b. It is hung up and does not fall into the empty box container 9 but is pushed up by the succeeding pot seedling box 1b and falls outside the empty box container 9 if left untreated. Therefore, it is necessary for the operator to always monitor whether the pot seedling box 1a pushed out from the guide frame 8 normally falls into the empty box storage container 9 or not.
[0005]
The present invention has been made in view of the above-mentioned problems of the prior art. In a transplanter equipped with an empty box storage container, the pot seedling box pushed out from the guide frame is automatically and reliably empty box storage container. The purpose is to drop inside.
[0006]
[Means for Solving the Problems]
The present invention inserts a flexible pot seedling box connected to a large number of pot-shaped seedling chambers into an inclined seedling stand and feeds them one by one downward, and projects an extrusion rod from the bottom side of the pot seedling box in the middle. Take out the pot seedlings one row at a time, and guide the pot seedling box after taking out the pot seedling along the guide frame curved so that the bottom side of the pot seedling box is the curved inner surface in the same direction as the entrance of the seedling platform. In the transplanting machine configured to drop the pot seedling box out of the guide frame into the empty box storage container, a discontinuous portion is formed in the guide frame that guides the upper surface side of the pot seedling box among the curved guide frames. In the vicinity of the outlet of the guide frame, a spring member is provided that abuts against the bottom side of the pot seed box that has come out of the guide frame and biases the pot seed box toward the empty box container. .
In this case, it is desirable to provide a regulating member that applies a feeding resistance to the pot seedling box in front of the discontinuous portion of the guide frame .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, with reference to FIGS. 1 to 3 will be specifically described the transplanter according to the present invention.
The transplanter (rice transplanter) shown in FIGS. 1 to 3 is provided with a flexible pot seedling box 1 (1a, 1b) in which a large number of pot-shaped seedling rooms are connected in the same manner as that of JP-A-11-243720. Inserted into the inclined seedling mount 11 and sent downward one row at a time. On the way, an extrusion rod (see FIG. 4) is ejected from the bottom side of the pot seedling box to take out the pot seedling one row at a time. The seedling box 1 is guided in the same direction as the entrance of the seedling stage 11 along a curved guide frame that guides the seedling box 1 so that the bottom surface side of the pot seedling box 1 is a curved inner surface. 1 is dropped into the empty box storage container 9.
[0009]
The guide frame includes upper left and right guide frames 12 and 13 for guiding the left and right sides of the upper surface side of the pot seedling box 1 (the opening side of the pot nursery), and an upper center guide frame 14 for guiding the central portion on the upper surface side. And a bottom left and right guide frame 15 that guides the left and right sides of the bottom side of the curved pot seedling box 1, and an edge guide frame (not shown) that guides both left and right edges of the pot seedling box 1.
Further, only the left and right edges 5 and 5 of the pot seedling box 1 are sandwiched from the front end of the front left and right guide frames 13 and 13 from the top and bottom direction (guided with a little play), and sent to the pot seedling box 1 Restricting members 16 and 16 are applied, and the frame 17 is always in contact with the bottom surface side of the pot seedling box 1 in the vicinity of the exit of the upper left and right guide frames 13, so that the pot seedling box 1 is placed on the empty box container 9 side. A spring member 18 that is biased toward the surface is installed.
[0010]
Furthermore, the rear upper surface left and right guide frames 12 and the front upper surface left and right guide frames 13 have a discontinuous portion (gap) 19 near the lower end, and both have substantially the same curvature in the vicinity of the discontinuous portion 19. The pot seedling box 1 is continuously and smoothly guided therethrough, but the rear end of the upper left and right guide frame 13 on the front side facing the discontinuous portion 19 is from the extension of the curvature. Inclined downward (inclined portion 20).
Since this discontinuous portion 19 exists, when the ear 6a at the rear end of the preceding pot seedling box 1a is disengaged from the front end of the upper left and right guide frame 12, as shown in FIG. The ear portion 6a is not bent along the curvature of the upper left and right guides 13 and extends in the tangential direction). Even if the ear portion 6a has been on the ear portion 6b at the front end of the succeeding pot seedling box 1b, It will be located below.
[0011]
The preceding pot seedling box 1a and the succeeding pot seedling box 1b are sent in abutting state while being sent along the guide frame, and once the ear part 6a is positioned below the ear part 6b in the discontinuous part 19, the form thereof is changed. Continue until exiting the guide frame 13. In particular, since the feeding resistance is applied to the preceding pot seedling box 1a by the regulating member 16, the abutting state is reliably maintained, and the positions of the ear part 6a and the ear part 6b are not reversed upside down again. As shown in FIG. 3, when the rear end of the preceding pot seedling box 1 a comes out of the guide frame 13, the pot seedling box 1 a is pushed into the empty box container 9 by the urging force of the spring member 18. To do. In addition, in FIG. 1, 21 is a planting part and 22 is a planting claw.
[0012]
The transplanter (rice transplanter) shown in FIG. 4 is in contact with the bottom surface of the rear end portion of the pot seedling box from the lower side in the vicinity of the exit of the guide frame instead of the discontinuous portion 19, the regulating member 16 and the spring member 18. Thus, a protruding member 24 that protrudes toward the empty box container 9 is provided.
The protruding member 24 moves back and forth in conjunction with the reciprocating motion of the push rod 26 via the link mechanism 25. The link mechanism 24 includes a lever 28 pivotally supported by the support member 27 and pivoted at one end, and a rear end of the member 24 pivotally supported. A lever 28 pivotally supported by the support member 27 and abutted against the base 29 of the push rod 26 30, a rod 31 connecting the other end of the lever 28 and the lever 30, a tension spring 32 stretched between the protruding member 34 and the lever 28, and a tension spring stretched between the lever 30 and the frame 33 34 and a guide roller 36 installed on the frame 35. The tension spring 34 presses the lever 30 against the base 29 of the push rod 26, and the urging force thereof becomes the thrust force of the projecting member 24. The tension spring 32 causes the projecting member 24 to abut on the guide roller 36, and the direction of advancement / retraction is determined. To regulate.
[0013]
When the push rod 26 moves backward by the link mechanism 25, the push rod 26 is pushed by the base 29, and the lever 30 swings leftward in FIG. 4, and the protruding member 24 moves backward. Conversely, when the push-out rod 26 advances, the lever 30 follows the base 29 by the urging force of the tension spring 34 and swings to the right in FIG. 4, so that the protruding member 24 advances toward the empty box container 9.
When the preceding pot seedling box 1a is still in the upper left and right guide frame 37, the protruding member 24 comes into contact with the bottom surface of the pot seedling box 1a and stops (in this case, the lever 30 swings to advance the base 29). However, as shown in FIG. 1, when the rear end of the pot seedling box 1 a exits the upper left and right guide frame 37, the projecting member 24 obliquely moves upward with the pot seedling box 1 a directed toward the empty box container 9. Push up.
Thus, since the protruding member 21 pushes the pot seedling box 1a obliquely upward, even if the ear part 6a of the pot seedling box 1a is on the ear part 6b of the subsequent pot seedling box 1b, the overlap is removed. Then, the pot seedling box 1a can be dropped into the empty box container 9.
[0014]
3 has the advantage that the structure is simple and does not require a drive mechanism. On the other hand, in the case of the system of FIG. 4, the ears of the preceding pot seedling box and the ears of the subsequent pot seedling box In order not to reverse the overlap, it is not necessary to make the guide frame itself have a feed resistance or to provide a regulating member that increases the feed resistance.
[0015]
