By binding and securing a piece to the bottom of the binding hole of the thick portion, an arc-shaped head of the piece is located on the bottom of the shovel blade, thus the arc-shaped head of the piece becomes in contact with the floor during shoveling, thereby minimizing wear of the tip of the shovel blade.

Description

마모방지수단이 구비된 합성수지제 삽날{SYNTHETIC RESIN SHOVEL PACE WITH PREVENTING ABRASION MEANS}Synthetic resin blade equipped with abrasion prevention means {SYNTHETIC RESIN SHOVEL PACE WITH PREVENTING ABRASION MEANS}

본 발명은 마모방지수단이 구비된 합성수지제 삽날에 관한 것으로서, 특히 삽날의 주마모부분에 간단한 구성으로 마모를 줄일 수 있는 보강수단을 구비하여, 삽날의 사용연한을 연장시킬 수 있게 한 것이다.The present invention relates to a synthetic resin blade provided with a wear preventing means, in particular, the main wear portion of the blade is provided with a reinforcing means capable of reducing wear with a simple configuration, so that the service life of the blade can be extended.

일반적으로 삽은 목재로 된 삽자루와 금속으로 된 삽날로 구성되나, 최근에는 삽자루와 삽날을 합성수지로 사출성형한 제품도 많이 사용되고 있다.In general, shovels consist of wooden shovels and metal blades, but recently, products made by injection molding of shovels and blades with synthetic resin are often used.

특히 제설용이나 축사의 오물처리용, 혹은 곡물 등을 담아옮길때 사용되는 삽날의 경우 선단부가 나란하게 일직선형으로 구성된 제품을 주로 사용하게 되며, 상기한 경우 합성수지로 사출성형한 삽날을 사용하게 된다.Particularly, in the case of a blade used for snow removal, for treating soil of a barn, or when carrying grain, etc., a product composed mainly of a straight line is used in parallel, and in the case described above, an injection molded blade made of synthetic resin is used. .

합성수지로 사출성형한 삽날의 경우 재질특성상 내마모성이 취약하여 삽날의 선단부가 쉽게 마모되므로 삽날을 자주 교체하여 주어야 하는 등의 단점이 있다.In the case of a blade that is injection molded from synthetic resin, it has disadvantages such as frequent replacement of the blade because the tip of the blade is easily worn due to its weak abrasion resistance due to material characteristics.

이러한 단점을 보완하기 위하여 합성수지로 사출성형한 삽날의 선단부에 보강수단을 구비하여 마모를 줄일 수 있도록 한 제품들이 제공되고 있다.In order to compensate for these disadvantages, products have been provided to reduce abrasion by providing reinforcing means at the tip of a blade that is injection molded with synthetic resin.

삽날에 보강수단을 구비하여 마모를 줄일 수 있도록한 선행기술을 검토하여 보면, 실용신안등록 제20-0410326호 "삽날에 보강부재가 형성된 삽"(특허문헌 1)과, 특허공개번호 10-2014-0010783호 "합성수지제 삽에서 삽 본체에 삽날보강판 결속구조"(특허문헌 2)와, 실용신안등록 제20-0454579호 "삽날끝이 보강된 합성수지제 다용도 삽"(특허문헌 3) 등이 등록된바 있다.Looking at the prior art to reduce the abrasion by providing a reinforcing means on the blade, Utility Model Registration No. 20-0410326 "Shovel with a reinforcing member formed on the blade" (Patent Document 1) and Patent Publication No. 10-2014 -0010783 "Synthetic resin shovel to the blade body to the blade reinforcement plate binding structure" (Patent Document 2), Utility Model Registration No. 20-0454579 "Reinforced synthetic resin shovel multi-purpose shovel" (Patent Document 3), etc. It has been registered.

상기 특허문헌 1의 기술내용은, 삽날의 선단부에 보강부재를 끼운 다음 나사못으로 체결고정한 구조이고, 특허문헌 2 및 특허문헌 3의 경우 합성수지제 삽날을 성형하는 과정에서 보강판을 일체형으로 사출성형하는 구조이다.The technical content of the patent document 1 is a structure in which a reinforcing member is fitted to the tip of the blade and then fixed with a screw, and in the case of patent documents 2 and 3, injection molding of the reinforcing plate integrally in the process of forming a synthetic resin blade Structure.

상기 특허문헌 1 내지 특허문헌 3의 경우에도 삽날의 선단부에 보강수단을 구비하여 사용시 삽날 선단부의 마모를 줄여 사용연한을 늘일 수 있는 장점이 있다.In the case of Patent Documents 1 to 3, there is also an advantage of providing a reinforcement means at the tip of the blade to increase the service life of the blade by reducing wear.

그러나 특허문헌 1의 경우 삽날 선단부에 보강부재를 끼운 다음 나사못으로 체결고정하는 구조로서, 조립에 불편함이 있을 뿐 아니라, 삽날 선단부에 두께가 있는 보강부재가 끼워져 있어 원활한 삽질에 어려움이 있다.However, in the case of Patent Document 1, it is a structure in which a reinforcing member is fitted to the tip of the blade and then fixed with a screw, which is not only inconvenient to assemble, but also has a reinforcing member having a thickness at the tip of the blade, which makes it difficult to smoothly insert.

특허문헌 2 및 특허문헌 3의 경우, 보강판을 사출성형하는 구조이나, 얇게 구성된 삽날의 선단부에 보강판을 일체로 사출성형하는데 어려움이 있을뿐 아니라, 보강판이 일체형으로 사출성형될 정도로 두껍게 성형할 경우에는 삽날의 무게가 늘어나고, 소재의 낭비가 초래되며, 또한 사출성형작업이 번거로운 등의 단점이 있는 것이었다.In the case of Patent Documents 2 and 3, not only is it difficult to injection mold a reinforcement plate integrally with a structure of injection molding a reinforcement plate, or a thinly constructed blade, and the reinforcement plate is molded thick enough to be injection molded integrally. In the case, the weight of the blade increased, material wasted, and there were disadvantages such as cumbersome injection molding.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail according to the accompanying drawings.

도 1 및 도 2는 본 발명이 적용된 합성수지제 삽날(10)의 사시도 및 저면구성도이고, 도 3 내지 도 6은 요부단면구성도이다.1 and 2 are a perspective view and a bottom view of the synthetic resin blade 10 to which the present invention is applied, and FIGS. 3 to 6 are sectional views of main parts.

본 발명의 삽날(10)은, 삽날(10)을 구성하는 본체(20)의 바닥(21) 전면 선단부(22)에 마모방지수단을 구비하여, 삽질시 삽날(10)의 본체(20) 선단부(22)의 마모를 최소화한다는 것이다.The blade 10 of the present invention is provided with a wear preventing means on the front end portion 22 of the bottom 21 of the main body 20 constituting the blade 10, the front end portion of the main body 20 of the blade 10 when shoveling It means that the wear of (22) is minimized.

본체(20)의 선단부(22) 마모를 방지하기 위하여 여러수단이 제공될 수 있겠으나, 발명에서는 간단한 구성을 적용하였다.Various means may be provided to prevent abrasion of the tip portion 22 of the main body 20, but a simple configuration is applied in the invention.

즉 합성수지제로 삽날(10)을 사출성형하되, 본체(20)을 구성하는 바닥(21)의 상면 선단부(22) 양측에 결속공(31)이 뚫린 후육부(30)를 구성한다.That is, the blade 10 is injection-molded with a synthetic resin, and the thickening portion 30 is formed with the binding holes 31 drilled on both sides of the upper end portion 22 of the bottom 21 constituting the main body 20.

상기 후육부(30)의 결속공(31) 저면에 피스(40)의 나사봉(41)을 억지결합하여 머리(42)가 결속공(31) 저면에 위치되게 한다.The screw 41 of the piece 40 is forcibly coupled to the bottom surface of the binding hole 31 of the thick portion 30 so that the head 42 is positioned on the bottom surface of the binding hole 31.

이때 피스(40)의 머리(42) 형상은 특별히 한정할 필요성이 없으나, 원호형으로 구성하여 삽질시 바닥의 돌출물과 걸림을 최소화하는 것이 바람직하며, 필요에 따라 피스(40)를 열처리하여 머리(42)의 내마모성을 높여 사용할 수도 있다.At this time, the shape of the head 42 of the piece 40 does not need to be particularly limited, but it is preferable to minimize the protrusion and jamming of the bottom when shoveling by configuring in an arc shape, and heat the piece 40 as necessary to heat the head ( It can also be used by increasing the wear resistance of 42).

또한 후육부(30)의 형상도 도 3에서와 같이 원형기둥모양으로 하거나,도 5에서와 같이 후육부(30)를 만곡돌출되게 하되, 후육부(30)와 바닥(21) 사이에 곡면부(32)를 구성하여 삽질시 이물질의 걸림이 없도록 할 수도 있다.In addition, the shape of the thick portion 30 is also in the form of a circular column as in FIG. 3, or to make the thick portion 30 curved as shown in FIG. 5, the curved portion between the thick portion 30 and the bottom 21 It is also possible to configure (32) so that there is no foreign matter jamming when shoveling.

후육부(30)에 구성된 결속공(31)의 내경(A1)은, 도 6에서와 같이 피스(40)의 나사봉(41) 외경(A)보다 작게 구성하여 강제로 나사결합되게 하여 견고한 결합이 되게 하는 것이 바람직하다.The inner diameter A1 of the binding hole 31 formed in the thick portion 30 is smaller than the outer diameter A of the screw rod 41 of the piece 40 as shown in FIG. 6, and is forcibly screwed to securely engage It is desirable to make this.

또한 결속공(31)의 길이(L1)는 피스(40)의 나사봉(41) 길이(L)보다 길게 구성하여, 후육부(30)의 결속공(31)에 나사결합된 피스(40)의 나사봉(41)이 후육부(30)를 관통하여 외부로 돌출되지 않게 한다.In addition, the length (L1) of the binding hole 31 is configured to be longer than the length (L) of the screw rod 41 of the piece 40, the piece 40 screwed to the binding hole 31 of the thick portion 30 The threaded rod 41 does not penetrate the thick portion 30 so as not to protrude to the outside.

삽날(10)의 바닥(21)에 돌출구성된 후육부(30)는, 피스(40)가 결합되는 얇은 바닥(21) 부분을 보강하는 기능과, 피스(40)의 견고한 결합을 유지하기 위한 것이다.The thick portion 30 protruding from the bottom 21 of the blade 10 is for reinforcing the portion of the thin bottom 21 to which the piece 40 is coupled, and for maintaining the solid coupling of the piece 40. .

본 발명을 실시함에 있어서, 삽날(10)의 바닥(21) 양측에 구성되는 후육부(30) 및 피스(40)는 도 4에서와 같이 중앙부에 부가설치하여 사용할 수 있으며, 상기한 경우 중앙부에 위치한 후육부(30)의 결속공(31)에 사용자가 피스(40)를 선택하여 조립사용할 수도 있다.In the practice of the present invention, the thick portion 30 and the piece 40 configured on both sides of the bottom 21 of the blade 10 can be used by being additionally installed in the central portion as shown in FIG. The user may select and use the piece 40 in the binding hole 31 of the thick portion 30 located.

이와 같이 구성된 본 발명은 삽날(10)은 삽날(10)의 연결관(50)에 통상의 삽자루(도시안됨)를 조립하여, 제설작업이나 축사의 오물처리, 혹은 곡물을 옮기는 작업등 다양한 용도로 사용한다는 것은 종래와 다를바 없다.In the present invention configured as described above, the blade 10 is assembled with a conventional shovel bag (not shown) to the connector 50 of the blade 10, and various uses such as snow removal, filth treatment of the house, or the operation of moving grains. It is no different from the conventional one.

그러나 발명에서 제공하고자 하는 삽날(10)은, 삽날(10)의 본체(20)를 구성하는 바닥(21)의 선단부(22) 양측에 결속공(31)이 뚫린 후육부(30)를 구성하고, 상기 결속공(31) 저면에서 피스(40)를 결합하여 피스(40)의 머리(42)가 바닥(21)의 선단부(22) 저면에 위치되게 함으로서, 삽질시 피스(40)의 머리(42)가 바닥과 접촉하게 되고, 따라서 합성수지로 구성된 삽날(10)의 선단부(22)가 바닥과 마찰하여 마모되는 현상을 줄일 수 있게 된다.However, the blade 10 to be provided in the present invention, constitutes the thick portion 30 through which the binding hole 31 is drilled on both sides of the tip portion 22 of the bottom 21 constituting the main body 20 of the blade 10. , By engaging the piece 40 from the bottom of the binding hole 31, so that the head 42 of the piece 40 is located on the bottom surface of the distal end 22 of the bottom 21, the head of the piece 40 during shoveling ( 42) is brought into contact with the floor, and thus, it is possible to reduce a phenomenon in which the tip portion 22 of the blade 10 made of synthetic resin rubs against the floor to wear.

본 발명에서 삽날(10)의 선단부(22)에 구성되는 후육부(30) 및 피스(40)는 삽질시 삽날(10)의 선단부(22)가 바닥과 가장 많이 접촉하는 부분에 위치되게 하는 것이 바람직하며, 일반적으로 삽날(10)의 바닥(21) 선단부(22) 양측 부분이 가장 심하게 마모되는 부분이기 때문에, 후육부(30) 및 피스(40)의 머리(42)가 삽날(10)의 선단부(22) 양측에 위치되게 하였다.In the present invention, the thick portion 30 and the piece 40 constituted by the tip portion 22 of the blade 10 are such that the tip portion 22 of the blade 10 is positioned at the portion that comes into contact with the bottom most when shoveling. Preferably, since the bottom part of the blade 21 and the both ends of the tip portion 22 of the blade 10 are the most severely worn parts, the thick portion 30 and the head 42 of the piece 40 are the blades 10. It was positioned on both sides of the tip 22.

그러나 상기 위치는 삽날(10) 성형시 조정될 수 있다.However, the position can be adjusted when forming the blade 10.

또한 삽날(10)의 바닥에 돌출구성되는 후육부(30)는 도 3에서와 같이 원형기둥형상으로 하거나, 도 5에서와 같이 만곡돌부형상으로 구성하여 삽질시 이물질의 걸림을 최소화할 수도 있으며, 사용중 피스(40)의 머리(42)가 마모되면 간단하게 피스(40)를 교체사용할 수 있어 편리하다.In addition, the thick portion 30 protruding from the bottom of the blade 10 may be formed into a circular pillar shape as shown in FIG. 3 or a curved stone shape as shown in FIG. 5 to minimize the jamming of foreign matter during shoveling. When the head 42 of the piece 40 is worn out during use, the piece 40 can be easily replaced and used.

이상에서 설명한 바와 같이 본 발명은 삽날을 사출성형하는 과정에서, 바닥 선단부에 결속공이 뚫린 후육부를 구성하고, 상기 후육부의 결속공 저면에서 피스를 나사결합하는 간단한 구성으로 삽날의 마모를 줄일 수 있어, 마모방지수단이 구비된 삽날을 간단하게 제작할 수 있을 뿐 아니라, 삽날의 내구성을 높여 사용연한을 길게 할 수 있게 된다.As described above, in the process of injection molding a blade, the present invention constitutes a thick portion with a binding hole drilled at the bottom end, and a simple configuration of screwing pieces at the bottom of the binding hole of the thick portion can reduce the wear of the blade. Thereby, it is possible to easily manufacture a blade equipped with a wear preventing means, as well as increase the durability of the blade, thereby extending the service life.
