Brief explanation of the drawing

[0014] FIG. 1 is a perspective view of the mulching pin striking machine of the present invention. FIG. 2 is an exploded view of FIG. 1. FIG. 3 is a side view and a top view of FIG. 1. FIG. 4 is an operational concept diagram showing the operation of the extension part and the striking part of the mulching pin striking device of the present invention. Specific details for implementing the invention

[0015] The present invention will be described in detail below using the attached drawings. However, since the attached drawings represent preferred embodiments of the present invention, the scope of the rights of the present invention is not limited by these drawings. Furthermore, even if a configuration is essential for implementing the present invention, specific descriptions of configurations that fall under known technology or that a person skilled in the art can easily implement from known technology are omitted.

[0016] As shown in FIGS. 1 to 4, the present invention includes a mulching pin striker comprising a handle (10) and a bundle member (20) fixedly coupled to one end of the handle (10).

[0017] The above-mentioned handle (10) is in the shape of a rod, with one end fixedly connected to the bundle member (20), and the other end has a handle. Preferably, as shown in FIG. 2, the end of the handle (10) connected to the bundle member (20) is formed as a tapered portion having an oblique slope to increase the bonding force with the bundle member (20).

[0018] The above bundle member (20) includes a body (21) to which a paper portion, which is one end of the bag (10), is attached, and a first extension unit (22) and a second extension unit (23) that branch out and extend from both upper sides of the body (21). Preferably, the first extension unit (22) and the second extension unit (23) are formed by extending in directions opposite to each other.

[0019] The above body (21) is integrally formed with an insertion part (211) in which a tapered part, which is one end of the bag (10), is received in an inner insertion space (211b) connected to one end opening (211a), and a connecting part (212) provided at the other end of the insertion part (211).

[0020] Preferably, the insertion space (211b) of the insertion part (211) is formed in a paper-like shape from one end, which is the opening (211a), toward the other end, which is the inner end, and the tapered part, which is one end of the bag (10), is formed to correspond to the shape of the paper-like insertion space (211b).

[0021] Additionally, preferably, the insertion part (211) can be deformed to a certain degree. A side cut (211c) is formed along the longitudinal direction on one side of the insertion part (211), and the side cut (211c) is formed to be connected to the opening (211a) and the insertion space (211b) of the insertion part (211). As the side cut (211c) is formed on one side of the insertion part (211) in this way, it becomes possible to secure a firm bonding force even if one end of the bag (10) does not exactly match the insertion space (211b) of the insertion part (211). In other words, when the end portion of the bag (10) is smaller than the insertion space (211b), striking the outer surface of the insertion portion (211) with a hammer or the like causes the side cut (211c) to narrow, and the insertion space (211b) of the insertion portion (211) is deformed to be in close contact with the outer surface of the end portion of the bag (10), thereby ensuring a bonding force. Conversely, when the end portion of the bag (10) is larger than the insertion space (211b), as the end portion of the bag (10) enters toward the insertion space (211b), the side cut (211c) opens up, allowing the end portion of the bag (10) to be in close contact with the insertion space (211b), thereby ensuring a bonding force.

[0022] Furthermore, preferably, a fastening hole (211d) is formed through the other side of the insertion part (211) and connected to the inner insertion space (211b). The fastening hole (211d) is provided to more firmly secure one end of the bag (10) inserted into the insertion space (211b) to the insertion part (211), and a fastening means (211e) is fastened through this fastening hole (211d) so that the insertion part (211) and one end of the bag (10) are secured even more firmly. Various known fastening means (211e) may be used as the fastening means (211e), and preferably, a screw or a nail is used.

[0023] As shown in FIGS. 1 to 3, the first extension unit (22) is integrally extended from one side of the connecting part (212) provided on the upper part of the body (21), and the first branching part (221), the extension part (222), and the striking part (223) formed in one direction are integrally connected to the connecting part (212).

[0024] One end of the first branch portion (221) is connected to one side of the connecting portion (212) of the body (21), and the other end is connected to the extension portion (222).

[0025] One end of the extension portion (222) is connected to the other end of the first branch portion (221), and the cross-section is formed to gradually expand along the extension direction extending from one end of the extension portion (222) toward the other end.

[0026] One end of the striking part (223) is connected to the other end of the extension part (222), and the other end is formed as a flat striking surface.

[0027] As described above, in the present invention, the extension part (222) is formed such that its cross-section gradually expands from one end to the other end, and the striking part (223) connected to the other end of the extension part (222) is formed such that the striking surface is relatively wider than that of the first branch part (221). Preferably, the extension ratio between the one end and the other end of the extension part (222) is 1:2 to 1:4. If the extension ratio is less than 1:2, the striking surface of the striking part (223) does not form a sufficient area and forms a relatively narrow striking surface, requiring considerable caution when striking the mulching pin (P). If the extension ratio exceeds 1:4, the extension part (222) becomes enlarged, causing the center of gravity to shift excessively toward the striking part (223), thereby increasing the burden on the wrist of the user using the striking device and potentially reducing work efficiency.

[0028] Additionally, as shown in FIG. 3, which illustrates the plan and side views of the present invention, the extension part (222) is preferably formed with a bias toward the other end of the insertion part (211) of the body (21). In other words, the first branch part (221), the extension part (222), and the striking part (223) constituting the first extension unit (22) that is continuously extended in one direction are formed such that the extension part (222) is formed with a bias toward the upper side (Y-axis) as shown in FIG. 3 (B) along a straight line (X-axis) of the extension direction, and the striking part (223), which is continuously connected to the other end of the extension part (222) in correspondence with the extension part (222) formed with a bias toward the upper side (Y-axis), is also formed with a bias toward the other end of the insertion part (211) along a straight line (X-axis) of the extension direction of the first extension unit (22).

[0029] As described above, the present invention is preferably formed such that the extension part (222) and the striking part (223) are deflected toward the other end of the insertion part (211) of the body (21), thereby operating advantageously for recovering the mulching pin (P) embedded in the ground.

[0030] As shown in FIG. 3, the second extension unit (23) is integrally extended from the other side of the connecting part (212) provided on the upper part of the body (21), and the second branch part (231) and the blade part (232) formed in one direction are integrally connected to the connecting part (212).

[0031] One end of the second branch portion (231) is connected to the other side of the connecting portion (212) of the body (21), and the blade portion (232) is connected to the other end. Preferably, the second branch portion (231) is formed by a bending bar (231a) that is bent downward to a certain thickness at the other side of the connecting portion (212), and a wedge bar (231b) that is formed in a wedge shape by narrowing the thickness from the bending bar (231a) toward the end.

[0032] The blade portion (232) is formed in a plate shape at the end of the second branch portion (231). Preferably, the blade portion (232) is formed in a semicircular or semi-elliptical shape as shown in FIG. 3(A) and is formed integrally with the wedge-shaped wedge bar (231b) of the second branch portion (231). In addition, the arc-shaped edge of the blade portion (232) having a semicircular or semi-elliptical shape is formed as a blade (232a). By using the blade (232a) of the blade portion (232), it is possible to use it as a hoe to easily dig up the ground, and it is also easy to cut and trim rolled vinyl, film, or non-woven fabric used as a cover to fit the target ground.

[0033] (A) and (A') of FIG. 4 are conceptual diagrams of a striking device operation in which the extension part (222) and the striking part (223) of the present invention are not biased to one side, and (B) and (B') are conceptual diagrams of a striking device operation in which the extension part (222) and the striking part (223) of the present invention are biased to one side.

[0034] Referring to FIG. 4, when a mulching pin (P) of the same size is retrieved from the ground, the blade portion (232) of the second extension unit (23) is inserted between the ground and the horizontal bar of the mulching pin (P), as shown in FIG. 4 (A) and (B). At this time, as the wedge bar (231b) of the second branching portion (231), which consists of a bent bar (231a) and a wedge bar (231b) among the second extension unit (23), is configured in a wedge shape toward the end, the blade portion (232) coupled to the wedge bar (231b) is guided to the wedge-shaped wedge bar (231b) and is easily inserted between the ground and the horizontal bar of the mulching pin (P). In this state, when the user forcefully pushes the handle (10) toward the first extension unit (22) formed opposite the second extension unit (23), the striking device of the present invention transitions to the states (A') and (B') of FIG. 4. When this happens, the extension part (222) and / or the striking part (223) formed in an expanded size among the second extension unit (23) of the bundle member (20) are fixed to the ground, and in this process, the striking device of the present invention operates on the principle of a lever. That is, to retrieve the mulching pin (P) embedded in the ground, the blade part (232) of the second extension unit (23) acts as the point of application of the lever, the handle (10) to which the user applies external force acts as the point of force, and the striking part (223) fixed to the ground acts as the fulcrum, so the user can easily retrieve the mulching pin (P) with a small amount of force. Here, when using the striking device in Fig. 4(B)(B') which has a configuration in which the extension part (222) and the striking part (223) are biased to one side, the effect of extending the operating range between the pivot point and the point of application occurs, so that the mulching pin (P) embedded in the ground can be pulled out relatively higher than the striking device in Fig. 4(A)(A') which has a configuration in which the extension part (222) and the striking part (223) are not biased for the same size mulching pin (P).As a result, the striking device having the deflection-forming extension part (222) and striking part (223) can achieve sufficient effect even when the handle (10) operating as a force point is operated for a relatively short period, thereby reducing the user's labor intensity and increasing work efficiency.
