Description

TECHNICAL FIELD The present invention relates to a transplanting trowel for horticulture, and more particularly to a multifunctional transplanting trowel for digging out growing seedlings and the like together with the surrounding soil and transplanting them to other soil.

2. Description of the Related Art Conventionally, when transplanting plants or planting seedlings in gardening work, a transplanting trowel (trowel, shovel, or shovel) consisting of an insert and a handle attached to the base end of the insert is also used. ) is commonly used. An ordinary transplanting trowel is mainly used to hold a handle, insert a small dish-shaped spoon provided at the tip of the handle into the soil vertically or at an arbitrary angle, and excavate to make a planting hole. used for

For example, Patent Literature 1 describes a transplanting trowel in which the handle is curved to improve structural toughness and workability. When using such a transplanting trowel to transplant a plant seedling or the like from a flower bed to a flowerpot, the soil around the seedling is excavated several times to dig up the seedling together with the soil. At that time, the operator is required to excavate carefully according to the size, shape and type of the plant to be transplanted so as not to damage the seedling due to interference (touching or bumping) of the transplanting trowel.

On the other hand, when transplanting a potted plant into the soil of a flowerbed, a digging jig as described in Patent Documents 1 to 3 is used. As a transplanting procedure, an operator first excavates a suitable range of the soil of the transplantation destination using an excavation jig to form a transplantation hole. Then, the plant is pulled out of the pot and transplanted into the excavated transplant hole, and if necessary, the surrounding area is mounded. As for the method of removing the plant from the pot, a transplanting trowel is used, or an operator pulls out the plant by hand or breaks the pot itself to remove the plant. For transplanting seedlings or plants with relatively small bulbs, a "horticultural transplanting scoop" disclosed in Patent Document 4 can be used.

Patent Document 2 discloses a scissors-type digging scoop in which semi-cylindrical scoop blades are attached to the lower ends of two symmetrical bars rotatably attached to a shaft pin so as to be parallel to each other. (See Patent Document 2.). Patent document 3 includes a shovel-shaped member and a fork-shaped member, which are respectively a semi-cylindrical insert, an attachment member formed at the base end of the insert, and an attachment member attached to the attachment member. The shovel-shaped member and the fork-shaped member are rotatably mounted by a detachable hinge portion with the recessed surfaces of the insertion member facing each other, making it easy to form a hole for planting, A planting tool applicable to a wide range of uses has been proposed (see Patent Document 3).

In addition, in Patent Document 4, two scoops facing in parallel are equipped with a handle with a blade at the lower end and a spring portion fixed to the handle at the upper end, and can be gripped together with the handle under the spring portion. By putting the belt across and holding it with your fingers on the pull belt at the required depth, the blades facing each other are pulled by the pull belt and each tilts inward, resulting in the separation of the two blades. A transplanting scoop capable of compressing and holding soil sandwiched between them has been disclosed (see Patent Document 4).

However, when excavating the soil, the larger the excavation range, the more times the conventional transplanting trowel needs to be inserted into the soil, requiring a great deal of labor. Furthermore, since the shape of the transplanting trowel is a semi-circular curved surface, the excavated soil tends to spill out, making it difficult to transplant the soil together with the root soil. In addition, although the excavating tool described in Patent Document 2 or Patent Document 3 is effective for excavating only the soil, when excavating both the plant and the soil around the plant, the place of use is naturally limited. This is because the connecting portion of the pair of scoops arranged facing each other is arranged in the center of the semicircle, so that the connecting portion interferes with the size and shape of the plant.

Therefore, for example, the second soldering iron is attached to the sliding box of the first soldering iron body so as to be slidable in the direction of the handle. In addition, the second soldering iron is rotatably attached to the first soldering iron body via a slide box, and the seedlings of flowers, vegetables, etc. A pair of cutting blades having long stems which are provided at the lower ends of the stems so as to be able to make clean cylindrical holes when planting various bulbs (see Patent Document 5). In addition, a composite scoop has been proposed in which the earth and sand holding surfaces of a pair of blade plates are pivotably connected by a connecting member so as to approach and separate from each other, and the seedling can be dug up together with the surrounding soil (Patent Document 6). reference.).
Further, in the inventions described in Patent Documents 1 to 6, once the soil is excavated, the soil adheres to the blade surface of the spoon, and when excavation work is continuously performed, the adhered soil becomes an obstacle. Therefore, it is necessary to remove each time, and the work efficiency is poor.
The present invention has also been made in view of the above problems of the prior art, and it is an object of the present invention to provide a multifunctional transplanting trowel that is easy to use without worrying about interference with the size of the plant to be transplanted, especially in the height direction. and
Another object of the present invention is to provide a multifunctional transplanting trowel that can easily remove soil adhering to the excavating plate (a portion corresponding to the spoon of the conventional transplanting trowel) during work and is easy to use. aim.

In order to achieve the above object, the first aspect of the present invention provides a multifunctional transplanting trowel, which has an excavating edge portion at the lower end and a handle portion at the upper end, and is formed with a concave surface and is partially curved in cross section. A pair of cylindrical excavation plates and guide grooves for holding the pair of excavation plates with their concave surfaces opposed to each other so as to be vertically movable and horizontally tiltable are provided, and are installed on the excavated soil. and a guide plate. Further, the invention according to claim 2 is the multifunctional transplanting trowel according to claim 1, wherein the guide groove is formed so that at least the concave surface of the excavation plate can slide. .

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings. FIG. 1 is an exploded perspective view showing a multifunctional grafting trowel according to the present invention.
As shown in FIG. 1, a transplanting trowel 1 according to the present invention includes a pair of excavating plates 2, 2 each having a partially cylindrical cross section, and a pair of excavating plates 2, 2 which can be moved vertically and horizontally. The excavating plates 2, 2 are used with their curved concave surfaces 2d, 2d facing each other. The drilling plates 2, 2 can be made of metal or plastic. Note that the partial cylindrical shape is a shape formed by a part of a cylindrical shape divided along the central axis direction. For example, a semi-cylindrical shape is also included in the partial cylindrical shape.

Sawtooth digging edges 2a, 2a are formed at the lower ends of the digging plates 2, 2, and thick gripping strips 2b, 2b following the curved shape of the digging plates 2, 2 are formed at the upper ends, and holes are drilled directly below them. Handle portions 4, 4 are formed by gripping holes 2c, 2c which are laterally elongated and into which human hands can be inserted, so that the upper ends of the excavating plates 2, 2 can be gripped by the operator. The reason why the excavating blades 2a, 2a are serrated is to easily cut the mulch film as described later. It does not have to be blade-shaped.

As shown in FIGS. 1 to 3, the pair of excavating plates 2, 2 of the transplanting trowel 1 are placed on the surface of the soil G (see FIG. 9 or 10), and are used to project the plant P to be transplanted. The concave surfaces 2d, 2d of the excavation plates 2, 2 are formed in opposing guide grooves (slits) 3a, 3a formed on the inner peripheral side of a disk-shaped guide ring 3 formed by opening a circular through hole 3b. They are inserted in a state in which they face each other, and are held so as to be vertically movable and horizontally tiltable. The guide grooves 3a, 3a are preferably formed so that the concave surfaces 2d, 2d of the excavation plates 2, 2 can slide in the guide grooves 3a, 3a when the corresponding excavation plates 2, 2 move up and down. That is, the groove width of the guide grooves 3a, 3a is equal to or slightly wider than the thickness of the concave surfaces 2d, 2d of the excavation plates 2, 2. As shown in FIG. By forming the guide grooves 3a, 3a in this way, when the excavation plates 2, 2 are pulled out from the guide ring 3 after excavating the soil, the concave surfaces 2d, 2d of the excavation plates 2, 2 are aligned with the guide grooves 3a, 3a. By sliding, the soil adhering to the concave surfaces 2d, 2d of the excavation plates 2, 2 can be easily removed. The convex surfaces 2e, 2e are formed on the back side of the concave surfaces 2d, 2d of the excavation plates 2, 2, and it is possible to easily remove the soil adhering to the convex surfaces 2e, 2e in the same manner as described above. Needless to say.

This guide ring 3 has a basic shape of a disk provided with opposing guide grooves (slits) 3a, 3a formed on the inner peripheral side, but as shown in FIG. In this case, a pair of recesses 3c, 3c formed so that the reinforcing rib portion of the spoon of the transplanting trowel can pass through, or as shown in FIG. The ends of the divided guide rings 3, 3 are pivotally supported and connected by shaft support means 5, 5 (indicated by screws in FIG. 5). A ring 3 in which either one of both ends is open and the through hole 3b can be arbitrarily enlarged with the other end (the portion supported by the shaft) as a fulcrum, as shown in FIG. By providing a notch d in a part of the seedling P, for example, when the seedling P is transplanted, the seedling P is passed through the notch d so that the guide rings 3, 3 can be arranged without interfering with the trunk of the seedling P. etc., it can be formed into a necessary shape according to the shape of the object to be planted.

Furthermore, as shown in FIG. 7, a step 6c having a diameter one size larger than that of the guide ring 3 and into which the guide ring 3 is fitted is provided. and pin insertion holes 6b are provided, and as shown in FIG. 3d may be provided to pin the guide ring 3 with a fixing pin 7, and a foot piece 8 may be provided for further fixing.

The diameter of the guide grooves 3a, 3a is a size that surrounds the perimeter of the plant to be excavated, and the excavation plates 2, 2 are inserted perpendicularly to the soil G along the guide grooves 3a, 3a. Next, as shown in FIG. 9(b), the handle portions 4, 4 of both the excavation plates 2, 2 are operated to spread outward, so that the excavated soil g is sandwiched between the excavation plates 2, 2 together with the plant P. do. In this state, the excavating plates 2, 2 are lifted upward to excavate the plant P and the excavated soil g, and then the plant P and the excavated soil g are transported to the transplant destination. FIG. 9(b) shows the state before transplanting to a flowerpot or the like. Then, the handle portions 4, 4 of the excavation plates 2, 2 are closed inward in the reverse order of the excavation, thereby widening the lower portions of the excavation plates 2, 2 to release the excavated soil g, and etc. In this state, the concave surfaces 2d, 2d or the convex surfaces 2e, 2e of the excavation plates 2, 2 are often covered with excess soil. However, after that, in order to move to the next work or finish the work, the handle portions 4, 4 of the excavation plates 2, 2 are lifted upward, and the excavation plates 2, 2 are moved into the guide grooves of the guide ring 3. By pulling out while inserting 3a, 3a, adhering soil can be easily removed. Preferably, if the excavation plates 2, 2 are pulled out from the guide grooves 3a, 3a so that the concave surfaces 2d, 2d or the convex surfaces 2e, 2e slide in the guide grooves 3a, 3a, the adhering soil can be removed more reliably. can do.

Next, FIG. 10 will be described. FIG. 10 has a diameter one size larger than that of the guide ring 3 shown in FIG. and the state of transplantation when using the stationary platen 6 formed with the pin insertion holes 6b.
As shown in FIG. 10(a), the fixing pins 7, 7 are driven into the pin insertion holes 6b, 6b of the stationary platen 6 placed on the surface of the soil G, and the tabs 6a, 6a, that is, the stationary platen 6 are removed. Fix to soil G. Then, the guide ring 3 is fitted to the stepped portion 6c of the fixed platen 6. As shown in FIG. In this state, the pair of excavation plates 2, 2 are inserted into the guide grooves 3a, 3a of the guide ring 3. As shown in FIG. The diameter of the guide grooves 3a, 3a is a size that surrounds the perimeter of the plant to be excavated, and the excavation plates 2, 2 are inserted perpendicularly to the soil G along the guide grooves 3a, 3a. Here, since the guide ring 3 is fitted to the stationary platen 6, the excavation plates 2, 2 are rotated along the guide grooves 3a, 3a, so that the soil G is formed into the shape of the guide grooves 3a, 3a. along it can be easily separated into excavated and non-excavated areas. Next, as shown in FIG. 10(b), the handle portions 4, 4 of both the excavation plates 2, 2 are operated to spread outward, so that the excavation plates 2, 2 hold the excavated soil g together with the plant P. do. The stationary platen 6 remains fixed to the soil G. In this state, the excavating plates 2, 2 are lifted upward to excavate the plant P and the excavated soil g, and then the plant P and the excavated soil g are transported to the transplant destination. FIG. 10(b) shows the state before transplanting to a flowerpot or the like. Then, the handle portions 4, 4 of the excavation plates 2, 2 are closed inward in the reverse order of the excavation, thereby widening the lower portions of the excavation plates 2, 2 to release the excavated soil g, and etc. Although not shown, if a handle portion having a predetermined length is provided at the upper end of the handle portions 4, the operator can work while standing by holding the upper portion of the handle portion. In this configuration, the gripping holes 2c, 2c of the handle portions 4, 4 may be omitted, and a gripping portion may be provided at the upper end of the handle portion. The handle portion may be detachably attached to the handle portions 4,4, or may be formed integrally with the handle portions 4,4.

In addition, there is an operation of digging a planting hole in the soil G in which the seedlings are covered with a synthetic resin mulch film. Mulch films are used in the cultivation of vegetables and flowers to achieve high quality and stable production. When drilling a planting hole in the soil G covered with this mulch film, the work of cutting the mulch film is essential. A cutter knife or a multi-film cutter that cuts out in a circular shape is usually used. However, these tools required considerable skill to work quickly. The saw blade 2a formed at the lower end of the drilling plate 2 of the present invention also functions as this multi-film cutter.
