Abstract
본 고안은 농업용 및 공원 녹지, 묘지등의 잔디를 깎는 배낭식예초기에 부착하여 사용하는 잔디깎이 보조기구로써, 잔디깎이 작업을 보다 안전하고 능률적이며, 아름답게 할 수 있게 하기 위한 것이다.The present invention is a lawnmower auxiliary device used for attaching to a lawnmower for farming, park greenery, cemetery, etc., to make the lawn mower work safer, more efficient, and more beautiful.
기존의 예초기는 원동기(또는 전동기), 동력전달예초봉, 예초칼날로 되어있고, 예초봉을 두 손으로 잡고 좌우로 휘둘러 잔디(잡초)를 깎게 된다. 이 예초칼날의 좌우에 스케이트 모양의 높이조정미끄럼판을 설치하고 이를 예초봉 하단부의 기어케이스에 고정시킴으로써 예초칼날과 지면이 항상 수평을 이루게 되는 동시에 지면과 일정한 간격을 유지하게 되어 잔디의 길이가 일정하게 잘리게 되며, 높이 조절미끄럼판부와 높이조절미끄럼판 지지봉, 체결판이 예취 칼날을 감싸고 있게 되어 예초 칼날이 땅에 박히지 않고 돌이나 나뭇가지 등의 위험물이 튀어오르는 것을 막게 된다. 또 작업의 방향이 우에서 좌로 휘두르는 한 방향 작업에서 전·후 양방향 작업으로 바뀌게 되어 예초칼날의 공회전이 줄어들고 작업 능률이 배가 되며, 예초봉과 예초칼날을 지면 위에 올려놓고 작업하게 됨으로 예초칼날의 회전진동이 지면으로 흡수되어 작업자의 팔 떨림을 줄일 수 있다.Conventional mowers consist of prime movers (or electric motors), power transmission mowing rods, and mowing blades, holding the mowing rods with both hands and swinging them from side to side to cut grass (weeds). Skate-shaped height adjustment sliding plates are installed on the left and right sides of the mowing blades and fixed to the gear case at the bottom of the mowing rods so that the mowing blades and the ground are always horizontal and at a constant distance from the ground, so that the length of the grass is constant. The height adjustment sliding plate part, the height adjustment sliding plate support rod, and the fastening plate surround the cutting blade so that the cutting blade does not get stuck in the ground and prevents the splashing of dangerous objects such as stones or branches. In addition, the direction of work is changed from one direction work that swings from right to left, before and after bi-directional work, which reduces the idling of the cutting blade and doubles the work efficiency, and puts the cutting stick and the cutting blade on the ground and rotates the cutting blade. Vibration is absorbed into the ground, reducing operator's arm tremors.
이로써 공원 녹지 및 묘지 등의 잔디(잡초) 관리를 보다 안전하고 능률적이며 아름답게 관리할 수 있게 된다.This makes it possible to more safely, efficiently and beautifully manage the management of lawns (weeds) such as park greenery and cemetery.
Description
본 고안은 예초기(배낭식 [도1] , 어깨걸이식 [도2] 등)에 관한 것으로써 기존의 예초기는 원동기(10)를 등에 메고, 예초봉(20)을 양팔로 잡고 좌우로 흔들어 저으면 예초봉(20) 끝의 예초칼날(70)의 회전에 의해 잔디나 기타 잡초를 예초하게 된다. 이때 잔디의 길이는 작업자의 감각에 의해 조절해야 되므로 잔디의 길이를 일정하게 자르기가 용이하지 않았다. 또 예초칼날(70)이 순간적으로 지면에 가까이 갈 때 땅에 박히게 되어 흙 또는 자갈 등을 튀기게 됨으로 작업자나 주위 사람에게 상해를 입힐 수 있었으며, 예초봉(20)을 양손으로 잡고 예초칼날(70)이 지면에 떠있는 상태에서 작업하게 됨으로 예초칼날의 회전 진동이 그대로 양팔에 전달되어 장시간 작업시 작업자의 보건에 많은 문제점이 있었다.The present invention relates to a lawnmower (backpack [Figure 1], shawl type [Figure 2], etc.), and the existing lawnmower carries the prime mover 10 on its back, and holds the mowing rod 20 with both arms and shakes it from side to side. If you mow grass or other weeds by the rotation of the mowing blade 70 at the tip of the mowing rod (20). At this time, the length of the grass should be adjusted according to the operator's sense, so it was not easy to cut the length of the grass constantly. In addition, when the mowing blade (70) is momentarily close to the ground is stuck in the ground and splashing soil or gravel, etc. could cause injury to workers or people around, and holding the mowing rod (20) with both hands mowing blade (70) ) Work in the floating state on the ground as the rotary vibration of the mowing blade is transmitted to both arms as it has a lot of problems for the health of the worker when working for a long time.
따라서 본 고안의 목적은 기존의 예초기에 용이하게 부착하여 사용할 수 있고, 간단한 기계적 조작에 의해 어떤 상황에서나 잔디의 길이가 일정하게 잘리게 되며, 예초칼날이 땅에 박히는 일이 없이 안전하게 작업을 할 수 있게 하고, 예초칼날의 회전 진동을 지면으로 흡수되게 하여 작업자의 건강을 보호하며, 예초 칼날의 공회전을 없애 작업의 능률을 높임으로써 에너지의 소모와 작업 시간을 줄이는데 있다.Therefore, the purpose of the present invention can be easily attached to the existing mowing machine, the length of the grass is constantly cut in any situation by a simple mechanical operation, the mowing blade can be safely worked without getting stuck in the ground. It protects the health of the worker by absorbing the rotary vibration of the mowing blade to the ground, and to reduce the energy consumption and working time by improving the efficiency of work by eliminating the idling of the mowing blade.

이러한 고안의 목적을 달성하기 위하여는 기존의 보급된 예초기(도1 또는 도2)에 높이조절 미끄럼판(301,302), 높이조절 미끄럼판 지지봉(201,202), 체결판(100)을 도3과 같이 조립하여 예초봉 끝부분의 기어 케이스(30)에 뚤려있는 안전커버(40)체결공에 고정시킴으로서 잔디깎이 보조기구(도3)가 제공되는 것이다.In order to achieve the object of this design, the existing height adjustment sliding plate (301, 302), the height adjustment sliding plate support rods (201, 202), fastening plate 100 assembling as shown in FIG. The lawn mower auxiliary mechanism (Fig. 3) is provided by fixing the safety cover 40 fastened to the gear case 30 at the end of the mowing rod.
이하 첨부된 도면을 참조로 하여 고안품의 조립 및 실시 예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described the assembly and embodiment of the invention.
높이조절 미끄럼판(301, 302)은 좌우로 고정되며 각각의 높이조절 미끄럼판(301, 302)에는 길죽한 모양의 체결공(311, 312, 313, 314)이 각각 2개씩 뚫려있고, 잔딧잎 토출구(321, 322)가 각각 1개 씩 뚫려있다. 이때 길게 뚫려진 체결공(311, 312, 313, 314)에 높이조절 미끄럼판 지지봉(201,202)을 끼우고 조임너트(211, 212, 217, 218, 221, 222, 227, 228)로 조여 고정하고 이때 체결하는 상태에 따라 예초 높이 및 높이조절 미끄럼판간의 폭(301과 302의 간격)이 조절되는 것이다.The height adjusting sliding plates 301 and 302 are fixed to the left and right, and each of the height adjusting sliding plates 301 and 302 has two fastening holes 311, 312, 313, and 314 formed in a jagged shape. One each of (321, 322) is drilled. At this time, insert the height-adjusting sliding plate support rods (201, 202) into the fastening holes (311, 312, 313, 314) long and fastened by tightening nuts (211, 212, 217, 218, 221, 222, 227, 228) At this time, the width (gap of 301 and 302) between the mow height and the height control sliding plate is adjusted according to the state of fastening.
체결판(100)은 좌우측을 절곡하고 중앙부에 기어케이스(30)에 조립되어있는 베어링과 회전축이 통할 수 있는 구멍을 뚫고, 그 주위에 글라스커버(50)의 체결공과 같은 3개의 체결공(121, 122, 123)을 뚫어 체결볼트(51, 52, 53)로 기어케이스(30)에 고정시키게 된다. 이때 체결공(121, 122, 123)은 길쭉하게 뚫어 서로 다른 기종에도 체결될 수 있게 한다. 또 체결판(100) 좌우측 절곡면의 사방에 삽입공(111, 112, 113, 114)을 뚫어 높이조절미끄럼판지지봉(201,202)을 끼우고 조임너트(213, 214, 215, 216, 223, 224, 225, 226)로 조여 고정시킨다.The fastening plate 100 bends the left and right sides and drills holes through which the bearing and the rotating shaft are assembled in the gear case 30 at the center thereof, and three fastening holes 121 such as the fastening holes of the glass cover 50 are formed around the fastening plate 100. , 122, 123 is to be fixed to the gear case 30 by the fastening bolts (51, 52, 53). At this time, the fastening holes 121, 122, 123 are elongated to be fastened to different models. In addition, the insertion plate (111, 112, 113, 114) in the four sides of the fastening plate 100, the left and right bent surfaces to insert the height adjustment sliding plate support rods (201, 202) and tightening nuts (213, 214, 215, 216, 223, 224). , 225, 226).
조립된 잔디깎이 보조기구를 글라스커버(50)을 통해 기어케이스(30)에 체결시키고 예초칼날(70)을 끼우면 체결판(100)의 두께만큼 틈이 좁아져 칼날이 원활하게 회전하지 못하게 된다. 이를 해소하기 위해 예초칼날홀더(61)을 끼우기 전에 체결판(100)의 두께와 같은 칼날 간격 넓힘용 워셔(400)를 삽입하고 순서에 따라 예초칼날(70)을 조립한다.When the assembled lawn mower auxiliary mechanism is fastened to the gear case 30 through the glass cover 50 and the cutting blade 70 is inserted, the gap is narrowed by the thickness of the fastening plate 100 so that the blade does not rotate smoothly. In order to solve this, before inserting the mowing blade holder 61, insert the washer 400 for widening the blade gap, such as the thickness of the fastening plate 100, and assemble the mowing blade 70 in the order.
이상의 방법으로 조립하고, 도3과 같이 체결하면 예초칼날(700)이 지면과 항상 일정한 간격을 유지하면서 작동하게 되어 조절해놓은 상태로 잔디의 길이를 일정하게 깎을 수 있고, 깎여진 잔딧잎이 잔딧잎 토출구(321, 322)로 연속적으로 빠져나와 칼날의 회전이 자유로우며, 예초봉을 전후로 움직여 작업을 하게 되어 공회전이 없게됨으로써 작업의 능률과 에너지의 소모를 줄일 수 있게 된다. 또 작업기를 지면에 놓고 작업을 하게 되어 칼날이 회전할 때 생기는 진동이 지면으로 흡수되어 팔의 떨림을 방지할 수 있게 되며, 보조기구가 칼날을 감싸고 있어서 흙이나 자갈이 튀어오르는 것과 칼날이 땅에 박히는 위험을 막을 수 있다.Assembling in the above manner, when fastened as shown in Figure 3 mowing blade 700 is always operated at a constant distance from the ground to cut the length of the grass in a controlled state, the cut grass leaf is cut The discharge of the blades 321 and 322 continuously exits the blades freely, and the mowing rod is moved back and forth to perform the work, thereby eliminating idling, thereby reducing work efficiency and energy consumption. In addition, the work machine is placed on the ground, and the vibration generated when the blade rotates is absorbed into the ground to prevent arm trembling.Auxiliary equipment surrounds the blade, so that soil or gravel springs up and the blade is on the ground. Getting hit can prevent the danger.
