Description

  The present invention relates to a transplanting trowel for horticulture.

  Conventionally, in horticultural work, when transplanting a plant or planting a seedling, it is common to use a transplanting trowel as described in Patent Document 1. Ordinary transplanting trowels are used for excavating by holding a handle and inserting a semi-cylindrical scoop body vertically or inclined into the soil.

  For example, when a plant is transplanted from a flower bed to a flower pot, 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, all the dug up plants are transplanted into pots.

  On the other hand, when transplanting a potted plant to the soil of a flower bed, a drilling tool as described in Patent Documents 1 to 3 is used. First, the operator uses the excavator to excavate an appropriate area of the transplant destination soil. Next, the plant is pulled out from the pot and transplanted to the excavated area, and soil is piled up if necessary. As a method for taking out the plant from the pot, the above-described transplanting iron is used, and an operator pulls out the plant by hand or breaks the pot itself to take out the plant. For transplanting relatively small plants such as plant seedlings and bulbs, the tools disclosed in Patent Document 4 can be used.

  However, when excavating the soil, the conventional transplanting trowel requires a lot of labor as the excavation range increases and the number of times it needs to be inserted into the soil increases. 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. Moreover, although the excavation tool of patent document 2 and patent document 3 is effective for excavation of only a soil, when excavating a plant and the soil around a plant together, a use location is naturally limited. This is because the excavation tool has a connecting portion connecting semi-circular scoops arranged opposite to each other at the center of the semi-circle, and the connecting portion interferes with the size and shape of the plant.

  Therefore, the present invention has a first feature that includes at least a pair of scoops for excavating soil and an arm for connecting the scoops so as to be openable and closable, and an end portion of the arms is rotatable with respect to the scoops. The second feature is that it is provided, and the third feature is that the arm is detachable from the scoop.

  Thus, since the scoop part is at least a pair in the present invention, the number of insertions into the soil is reduced compared to the use of the scoop alone. In addition, since the scoop unit has an opening / closing mechanism, it is possible to hold an object such as a plant or earth and sand, and the object held in the space of the scoop unit is not easily spilled. Furthermore, since the arm is detachable, the insertion position of the scoop part increases the degree of freedom by connecting the scoop part to the soil and then connecting again with the arm. Therefore, it can be used without interfering with plants, and by removing the arm, it can also be used as a conventional transplanting iron and its application is expanded. In addition, since the arm can be further fixed, it can be transported to the transplant destination in the shape of excavation, and the work efficiency is increased.

It is a perspective view which shows Example 1 of the grafting iron which concerns on this invention. It is a disassembled perspective view which shows the structure of the arm part of the transplanting iron which concerns on this invention. 2 is a cross-sectional view showing a usage state of Example 1. FIG. It is sectional drawing which shows the use condition of the other Example of the grafting iron which concerns on this invention.

  Hereinafter, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings, but it is needless to say that the present invention is not limited to this embodiment.

  The structure of the transplanting iron according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a transplanting iron of the present invention, and FIG. 2 is an exploded perspective view of an arm portion of the present invention. As shown in FIG. 1, the scoop portions 1 and 1a are made of a semi-cylindrical excavation body 2 and a rod-shaped handle portion 3 made of metal or plastic, and the excavation body 2 is formed so as to be gradually reduced toward the tip. The handle 3 is fixed to the base end. The scoop portions 1, 1 a are arranged so that the curved portions face each other, and both end surfaces of the scoop portion 1 are connected to the end portions of the arm portion 4. The scoop part 1 a is also connected to the arm part 4 at both end surfaces, similarly to the scoop part 1.

  As shown in FIG. 2, the arm portion 4 includes an arm plate 6 and a fastening member such as a connecting screw 5 that are appropriately curved in accordance with the cylindrical shape of the excavated body 2. Both ends of the arm plate 6 are perforated, one having the role of the connecting shaft 5a and the other of the rotating shaft 7a. A connecting shaft 5a which is the center of the arm portion 4 is fastened by a connecting screw 5 and a nut 11, and a spring washer 8, a flat washer 9, an arm plate 6 which is attached to the scoop portion 1, a rubber packing 10 which is an elastic body, and a scoop portion. The arm plate 6 attached to 1a is fastened. Rotating shafts 7a serving as both ends of the arm portion 4 are fastened by screws 7 and nuts 11, and an arm plate 6, an elastic rubber packing 10, an excavating body 2, and a spring washer 8 are sandwiched therebetween. With such a structure, the arm portion 4 has a total of six fulcrums, and can be freely opened and closed to change the inner volume between the scoop portions 1 and 1a. In this embodiment, the spring washer 8, the flat washer 9, and the rubber packing 10 are used to make the movement of the arm plate 6 smooth. However, this is only a preferred example of the fastening method.

  FIG. 3 is a cross-sectional view showing a use state of the first embodiment of the present invention. As shown in FIG. 3, the scoop portions 1 and 1a are spread on both sides with the connecting shaft 5a of the arm portion 4 as a fulcrum. The width to be expanded is wider than the plant so that it can be excavated to the soil around the plant. FIG. 3A shows a state in which the scoop portions 1 and 1a are inserted perpendicularly to the soil. Next, it moves so that the handle | steering-wheel part 3 may be tilted horizontally by using the rotating shaft 7a as a fulcrum, and the excavation soil 12 in the space of the excavation body 2 is clamped. FIG. 3B shows a state where the screws of the connecting shaft 5a and the rotating shaft 7a are tightened and the arm portion 4 is held. The handle 3 is grasped and pulled up, and after excavating the plant and surrounding soil, it is transported to the transplant destination. FIG. 3 (C) shows the state of transplanting to the flower pot 13 after transportation. This time, the screws of the connecting shaft 5a of the arm portion 4 and the rotating shaft 7a are loosened in the reverse procedure of excavation, and the rotating shaft 7a is a fulcrum. The excavated body 2 releases the excavated soil 12 by transplanting the handle portion 3 in the vertical direction, and transplants it to the flower pot 13.

  Next, a second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 4A, the arm part 4 is removed, and each of the scoop parts 1 and 1a is inserted into the soil at an arbitrary angle so as not to interfere with the plant. The handle part 3 is moved horizontally inward to hold the excavated soil 12 in the space of the excavated body 2. The arm portion 4 to which the connecting screw 5 of the connecting shaft 5a is tightened is attached to the scoop portions 1 and 1a together with the screw 7 and tightened and fixed. FIG. 4B shows a state where the handle 3 is grasped and pulled upward. Subsequent transplantation operations are the same as those in the first embodiment.

  The effect | action is demonstrated about the Example mentioned above. Compared with the case where the scoop is used alone, Example 1 excavates with a plurality of scoops at the same time, so that the work efficiency is improved. In addition, it is excellent in operability by connecting the scoop with an arm, and furthermore, holding the arm can prevent spillage during transportation, so that the transplanting operation can be performed reliably.

  In Example 2, excavation according to the size and shape of the plant is possible by separating the transplanting tool into two. Moreover, it can be used as a conventional scoop by separating it into two.

  In addition, this invention is not limited to the said Example. For example, the arm and scoop may be integrated, or the number of arm plates may be increased or decreased. The arm material may be an elastic body that moves flexibly, and the arm may be provided with a mechanism that can be attached and detached with one touch. Needless to say, various modifications can be made without departing from the gist of the present invention.
