Description

  The present invention relates to a seedling supplemental transplanting machine that reduces the labor of supplementary seedling planting work that is supplementary to machine transplanting.

  At present, in the cultivation of root vegetables such as beets and onions, and vegetables such as cabbage, lettuce, and Chinese cabbage, machine transplant cultivation using a fully automatic or semi-automatic transplanter has become established. In this mechanical transplantation cultivation, seedling seedlings such as pot seedlings are generally used, and these seedlings are planted at regular intervals in the field by a transplanter equipped with various transplantation mechanisms.

  However, according to such machine transplantation, the planting interval is too large due to the accuracy of the transplanter, etc., the seedlings are blown away in the wind after planting, or the rooting is bad and withered, and at a predetermined interval. It can often happen that a stock is missing in the row of seedlings to be planted.

  Therefore, in order to increase the intensiveness in the field, it is always necessary to carry out supplementary planting work for transplanting seedlings individually when the seedling row is missing, after one or two months from the transplanting work by the transplanter. It has become. For example, in beet cultivation in cold regions, the seedlings grown in the house from February to March are transplanted to the field using an automatic transplanter, and then the above-mentioned supplementary planting work is performed from the end of April to the beginning of May when the seedling establishment can be confirmed. It is generally done.

  In this supplementary planting work, an operator hangs a container containing a large number of seedlings on his shoulder, looks for the location where the stock is missing, moves, and when that location is found, plants the seedling in the container. For the person, the standing work at the time of moving and the bending work at the time of planting are repeated.

  In order to reduce the labor of such a supplementary planting work, a pot seedling planting machine that can plant seedlings one by one while standing has been conventionally employed (for example, see Patent Document 1 below).

  The supplementary planting operation employing this conventional technique will be described with reference to FIG. 1. The body is suspended by holding the handle J2 attached to the upper part of the cylinder J1, and the pot seedling held by another hand is transferred from the upper opening J1a to the cylinder. When thrown into J1, the pot seedling thrown by the punching machine J3 at the bottom of the cylindrical body J1 is temporarily received. In this state, the machine body is pushed down by holding the handle J2, and the punching machine J3 is pushed into the ground to the position of the regulating member J3a. Then, when the lever J4 is squeezed strongly, the punching machine J3 opens to the left and right like a hook through the coupling mechanism J5, and a planting hole is formed on the ground surface and a pot seedling is released. Therefore, if the aircraft is pulled up from the ground surface while holding the lever J4, seedlings are planted in the planting hole. When the lever J4 is released, the lever J4 is returned by the spring J6, so that the punching machine J3 returns to the original closed state.

  According to such a conventional technique, the work of pushing the drilling machine J3 into the ground and opening it is a considerable work because of the resistance in the soil, and every time a seedling is planted, it is applied to the grip strength, wrist and arm. Since local fatigue is accumulated, the use of conventional supplementary transplanters does not necessarily reduce labor.

  In addition, it may be possible to electrify the opening / closing operation of the drilling machine J3 described above. However, if a power supply or the like is mounted on the machine body, the machine body gravity will increase accordingly, so it is useful to push the machine body into the ground and pull it up. Considering that planting work is repeated, there is a problem that this does not necessarily reduce labor.

  In addition, since the body length of the transplanter is fixed, there is a problem that the operator cannot work comfortably unless the height of the worker matches the body length.

  The present invention has an object to cope with such a problem, and can reduce labor during repeated planting work, and can provide comfortable workability regardless of the height difference of workers. It aims at providing the seedling supplementary plant machine obtained.

  In order to achieve such an object, according to the present invention, for example, seedlings are introduced from the upper opening of a tubular body that can be suspended, and a planting hole forming opening attached to the lower end of the tubular body is opened in the ground. The planting hole transplanting machine drops seedlings into the formed planting hole, and the planting hole forming port is a bowl-shaped opening and closing unit that pivots around a rotation fulcrum. It comprises an opening / closing member, and a lower end portion is fixed to the opening / closing member, and includes an opening / closing operation rod extending upward, the turning fulcrum serving as a lever fulcrum, The opening / closing member can be freely opened and closed by swinging the upper end of the opening / closing operation rod using the upper end of the opening / closing operation rod as a leverage point.

  In another aspect, the opening / closing operation rod includes a horizontal bent portion fixed to the outer periphery of the upper end of the opening / closing member and a vertical portion extending upward along the cylindrical body.

  In addition, a handle portion is attached to the side surface of the upper portion of the cylindrical body, and an upper end portion of the opening / closing operation rod is disposed along a side surface of the cylindrical body different from a position where the handle portion is attached. Features.

  In another aspect, the cylindrical body is formed to be extendable up and down.

  In the present invention having such a feature, the planting hole forming port is composed of a bowl-shaped opening / closing member that opens and closes by rotating around a rotation fulcrum, and a lower end portion is fixed to the opening / closing member and extends upward. An opening / closing operation rod, the upper end of the opening / closing operation rod using the pivot fulcrum as the lever's fulcrum; The opening / closing member can be freely opened and closed by swinging the part. According to this, by making the pivotal fulcrum of the opening / closing member the fulcrum of the lever, it becomes possible to secure a large distance from the fulcrum to the upper end of the opening / closing operation rod as the lever's power point. Thus, compared with lever operation with a fulcrum at hand, the force required to open and close the planting hole forming port can be greatly reduced.

  Further, the opening / closing operation rod is composed of a horizontal bent portion fixed to the outer periphery of the upper end of the opening / closing member and a vertical portion extending upward along the cylinder, so that the above-mentioned operating point is securely fixed to the opening / closing member by the horizontal bent portion. Moreover, the rotation fulcrum serving as the lever fulcrum and the fixing portion serving as the action point can be brought close to each other. As a result, the force required for the swing operation of the power point formed at the upper end of the vertical portion can be reliably reduced.

  In addition, a handle portion is attached to the side surface of the upper portion of the cylinder, and the upper end portion of the opening / closing operation rod is disposed along the side surface of the cylinder different from the position where the handle portion is attached. The handle portion can be gripped and the upper end portion of the opening / closing operation rod can be swung with the other hand, so that good operability can be obtained.

  In addition, since the cylinder body can be expanded and contracted vertically, the body length can be adjusted by adjusting the expansion and contraction of the cylinder body according to the height of the operator, so that comfortable workability can be achieved regardless of the size of the body. Can be obtained.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a perspective view showing the whole seedling transplanter 1 according to the embodiment of the present invention, and FIG. 3 is a perspective view showing the operation of the seedling transplanter 1 according to the embodiment of the present invention.

  A seedling transplanter 1 according to an embodiment of the present invention introduces seedlings from an upper opening 10a of a tubular body 10 that can be suspended, and opens a planting hole forming port 11 attached to the lower end of the tubular body 10 in the ground. The seedling is dropped into the formed planting hole.

  And the seedling transplanter 1 in embodiment of this invention makes the cylinder 10 telescopic. That is, the cylindrical body 10 is composed of a first cylindrical body 10A and a second cylindrical body 10B having a larger diameter than that, and the lower end of the first cylindrical body 10A is inserted from the upper end of the second cylindrical body 10B. And a fixing portion 10C by a wedge screw portion or the like is provided so that it can be fixed in a predetermined sliding state. Thus, the length of the cylindrical body 10 can be expanded and contracted by adjusting the sliding amount of the first cylindrical body 10A inserted into the second cylindrical body 10B.

  A handle portion 12 is attached to the upper portion of the first cylinder 10A, and a stepping portion 13 is attached to the lower portion of the second cylinder 10B in which the planting hole forming port 11 is provided at the lower end. Then, holding the handle portion 12 with one hand, the lower end of the planting hole forming port 11 is pierced at the planting position, and the stepping unit 13 is depressed to insert the planting hole forming port 11 into the ground.

  And according to the seedling transplanter 1 in the embodiment of the present invention, the planting hole forming port 11 is composed of a hook-shaped opening / closing member 11A that opens and closes the planting hole forming port 11 by rotating around the rotation fulcrum. The lower end of the opening / closing member 11A is fixed, and an opening / closing operation rod 20 extending upward is provided. The opening / closing operation bar 20 includes a horizontal bent portion 20A that is fixed to the outer periphery of the upper end of the opening / closing member 11A and a vertical portion 20B that extends upward along the cylindrical body 10. Further, while the handle portion 12 described above is attached to the side surface of the upper portion of the cylinder 10 (10A), the upper end portion of the opening / closing operation rod 20 extends along a side surface different from the position where the handle portion 12 is attached. 20f is arranged.

  The opening / closing operation bar 20 uses the pivoting fulcrum of the opening / closing member 11A described above as the lever fulcrum, the lower end of the opening / closing operation bar 20 and the fixing portion of the opening / closing member 11A as the lever's action point, and the upper end 20f of the opening / closing operation bar 20. As the leverage of the lever, the opening / closing member 11A is opened and closed freely as shown by an arrow B by swinging the upper end portion 20f of the opening / closing operating rod 20 as shown by the arrow A in FIG. Further, one end of a spring 21 is attached to the middle stage of the vertical portion 20B of the opening / closing operation rod 20, and the other end is attached to the side surface of the cylinder 10 (10B). The operation to close is assisted.

FIG. 4 is a part view partially showing a structural example of the opening / closing operation rod 20 and the opening / closing member 11A described above (FIG. 4A is a side view, and FIG. 4B is a front view). Horizontal bent portion 20A which corresponds to the lower end of the opening and closing bars 20 are secured along the upper end periphery of the beak-shaped opening and closing member 11A, the upper end portion of the opening member 11A and the shaft support 11A _O is formed integrally Yes. Shaft supporting hole is formed to be pivotally supported by the pivot point O in the end of the shaft support 11A _O. Accordingly, the lower end of the opening and closing bars 20 would have been secured to the opening and closing member 11A and the shaft support 11A _O integrally.

  Accordingly, when the upper end portion 20f of the opening / closing operation rod 20 is swung, the opening / closing member 11A is rotated around the rotation fulcrum O, and the planting hole forming port 11 is opened / closed. The pivot fulcrum O becomes the lever fulcrum, the fixed portion at the lower end becomes the point of action, and the upper end 20f becomes the force point, and the lever acts. Since the pivot fulcrum O is the lever fulcrum, the distance from the fulcrum to the action point can be set short, and the distance from the fulcrum to the force point can be set large. The opening / closing operation of 11A can be performed.

  Explaining how to use the seedling transplanter 1 according to this embodiment, first, the length of the body 10 is adjusted so that it can be easily used according to the height of the operator by adjusting the expansion and contraction of the cylinder 10. Then, when reaching the supplemental planting site, the handle body 12 is held with one hand, the machine body is suspended, and seedlings such as pot seedlings held with another hand are put into the cylindrical body 10 from the upper opening 10a. Then, since the inserted seedling is temporarily received by the planting hole forming port 11 that is always closed, in that state, the handle portion 12 is held, the tip of the planting port 11 is pierced at the planting location, and the stepping unit 13 is stepped on. By pushing down the machine body, the planting hole forming port 11 is inserted into the ground.

  Then, by swinging the upper end portion 20f of the opening / closing operation rod 20, the planting hole forming port 11 is opened, a planting hole is formed on the ground surface, and the seedling is discharged into the hole. Therefore, if the body of the seedling transplanter 1 is pulled up from the ground surface while holding the handle portion 12 and operating the opening / closing operation rod 20 in one direction, seedlings are planted in the planting hole. At this time, the handle portion 12 is attached to one side surface of the upper portion of the cylindrical body 10 and the upper end portion 20f of the opening / closing operation rod 20 is disposed along the side surface opposite to the one side surface. Thus, the holding of the machine body by the handle portion 12 and the operation of the opening / closing operation rod 20 can be performed smoothly.

  According to this, since the cylinder 10 can be extended and contracted, it is possible to adjust the body length by adjusting the expansion and contraction of the cylinder 10 according to the height of the worker, so that the work can be performed regardless of the height. It can be performed. Further, since the pivot fulcrum O of the opening / closing member 11A is used as a lever fulcrum, it is possible to ensure a large distance from the fulcrum to the upper end 20f of the opening / closing operation rod 20 serving as the lever's power point. Compared with lever operation with a fulcrum at hand as in the technique, the force required to open and close the planting hole forming port 11 can be remarkably reduced.

  As described above, the seedling transplanter 1 according to the embodiment of the present invention can provide comfortable workability regardless of the height difference of the operator and can easily open and close the planting hole forming port 11. Therefore, it is possible to reduce the labor when repeatedly planting.
