Description

  In the present invention, for example, when transplanting a seedling, first, a transplant hole of a predetermined size is excavated in the transplant destination soil to which the seedling is to be transplanted, and then the currently planted seedling is excavated together with the surrounding soil. For transplanting into the transplant hole.

  Conventionally, when transplanting a plant such as a park, first, a hole for transplantation of a predetermined size is first drilled in a soil to be transplanted with a conventionally known scoop, and then a seedling currently planted is In addition, a well-known scoop was dug out together with the surrounding soil and transplanted into the transplant hole.

  In horticultural work, when transplanting plants or planting seedlings, a well-known transplanting iron is used. This transplanting iron grips the handle and makes the blade surface of the semi-cylindrical scoop perpendicular or inclined to the soil. Used to insert and dig.

  For example, when a plant is transplanted from a breeding place to a flower bed, the periphery of the plant is excavated several times, and the plant is dug together with the soil. At this time, the operator is excavating according to the shape and type of the plant so that the transplanting iron does not interfere with the plant and damage it. Then, every plant dug up is transplanted into a flower bed.

  In addition, when transplanting a potted plant to a flower bed soil, an operator first excavates the transplant destination soil within an appropriate range using the scoop. Next, the plant is taken out from the pot (pot) and transplanted to the excavated portion, and soil is piled up if necessary. The method of taking out the plant from the pot (pot) uses the transplanting iron, and the operator takes out the plant with the soil by turning the pot (pot) upside down.

However, when excavating the soil, the conventional transplanting iron is short and the working posture is bent, so that it is inserted into the soil only by the arm force, which requires considerable labor. Furthermore, since the shape of the transplanting iron is a semicircular curved curved surface, the excavated soil is easily spilled and it is difficult to transplant the entire root soil.
Therefore, as a means for solving such a problem, a transplanting iron having a pair of blade surfaces facing each other as described in Patent Document 1 has been proposed.

  JP2013-59265A

The transplanting trowel described in Patent Document 1 described above is small and does not have a long handle like a normal scoop.
Therefore, it is suitable for transplanting a very small amount of flowers (seedlings), but not suitable for transplanting a large amount of flowers (seedlings). If an attempt is made to transplant such a plant, the handle portion must be long, but if it does so, unnecessary stress in the twisting direction may be applied to the pair of connecting portions, which is likely to break. In order to prevent this damage, the connecting portion must be made robust, and an increase in size and cost of the connecting portion is inevitable.

  In view of the above-described conventional problems, the present invention provides an inexpensive and simple composite scoop that can be used for plants that are transplanted using a scoop.

(6) In the present invention, one end of the displacement preventing member is fixed to one handle, and the other end extends in the direction of the other handle, and the other handle is slidably held from the side. It is preferable to be provided.
When configured in this way, even if one of the handle portions and the other handle portion are subjected to unnecessary stress in the direction intersecting the swinging direction, that is, the twisting direction, at the connecting member portion, And the other handle are not twisted.

(7) In this invention, it is preferable that the other end of the said displacement prevention member is exhibiting the circular arc shape which has an internal diameter larger than the external shape of said other holding part.
If comprised in this way, when assembling and disassembling one scoop and the other scoop, the other handle can be easily put in and out of the arc portion.

(8) In the present invention, the handle portion is a metal pipe, and is formed in a double manner from a portion where the blade plate is fixed to a portion where the connection piece is fixed. preferable.
If it is formed in a double manner from the portion where the blade plate is fixed to the portion where the connection piece is fixed, the strength of the portion increases and the operator can easily apply force.

  (9) In the present invention, the handle portion extends linearly from the portion where the blade plate is fixed in the direction of the grip portion, the extension portion is slightly bent inward, and the grip portion is the extension portion. It is preferable that it is bent at right angles to the outside.

In the present invention, the connection member is provided between the grip portion and the blade surface, and one handle portion and the other handle portion intersect the swing direction between the connection portion and the grip portion. Since a displacement preventing member that prevents mutual displacement in the direction is provided, it is assumed that unnecessary stress is applied to the connecting member in the direction intersecting the swinging direction between the handle portions, that is, the twisting direction. However, the displacement preventing member is not displaced, and the connecting portion is not damaged.
Therefore, when transplanting a large planting, it is possible to use a scoop having a long handle.
