Description

예초용 커터{The cutter for weeder}The cutter for weeder}

본 발명은 밭이나 들에 식생되는 곡식, 풀, 잡목 등을 베는 예초용 커터에 관한 것으로, 특히 예초기와 결합되는 회전판의 양측으로 절단체의 후측이 고정되는 고정체를 각각 구성함으로써, 상기 회전판에 절단체의 교체 및 고정이 용이하게 이루어지면서도 절단체과 고정체의 결합 상태가 견고해져 예초작업 중에 절단체가 이탈되는 현상을 방지하여 예초작업의 편리함을 도모하는 예초용 커터에 관한 것이다.The present invention relates to a lawnmower cutter for cutting grain, grass, scrub, etc. vegetation in a field or field, and in particular, by forming a fixed body fixed to the rear side of the cutting body to both sides of the rotary plate coupled to the lawnmower, The present invention relates to a cutter for mowing to facilitate the replacement and fixation of the cutting body while preventing the phenomenon of the cutting body being detached during the mowing operation due to a firm coupling state between the cutting body and the fixing body.

일반적으로 밭이나 들에 식생되는 곡식, 풀, 잡목 등이 많이 자란 곳에서 낫이나 삽 등과 같은 도구를 이용하여 예초작업을 수행하여 왔으나 이러한 방식은 육체적인 피로와 비효율적인 작업능력에 의해 지양되고 있으며, 최근에는 모터를 주 동력원으로 하여 동력전달축에 동력을 전달하며 동력전달축 단부에 절단체가 형성된 회전판이 결합되는 예초기를 개발하여 낫과 삽과 같은 도구 대신에 예초기 절단체를 잡초나 잡목 등에 접근시켜 절단체의 회전력을 이용해 이들을 절단함으로써 예초작업을 수행하여 왔다.In general, mowing works have been carried out using tools such as sickle or shovel in areas where vegetation, grass, and cultivation have grown in the fields or fields, but this method is avoided due to physical fatigue and inefficient work ability. Recently, we developed a mower that transmits power to the power transmission shaft using a motor as a main power source and combines a rotary plate formed with a cutting body at the end of the power transmission shaft to replace weeds and shovels instead of tools such as sickles and shovels. Mowing has been performed by approaching and cutting them using the rotational force of the cuttings.

그러나, 상기와 같은 예초기 절단체는 금속재로 이루어져 예초작업이 용이한 장점은 있으나 예초작업 중에 지면의 돌이나 지면 바닥에 수시로 마찰되어 절단체의 손상을 야기시키며 상기 손상된 절단체의 파편들이 회전력에 의해 사방으로 비산되어 작업자 및 그 작업주위반경에 위치한 인원에게 상해를 입히는 등의 안전사고가 매우 빈번히 발생되었고, 금속재의 예초기 절단체가 파손되어 손상된 절단체에 의해 절단체 전체를 교체해야 하는 경우가 많아 교체 비용에 따른 경제적인 손실 및 교체 작업의 번거로운 문제점이 발생하였다.However, the above-mentioned cutting device is made of a metal material has the advantage of easy mowing work, but during the mowing work often rubbed on the stone of the ground or the bottom of the ground causing damage of the cutting body and debris of the damaged cutting body by the rotational force Safety accidents such as injuries to workers and personnel located in the radius of operation were very frequently occurred, and cutting cutters made of metal were often damaged and the whole cut bodies had to be replaced by damaged cut bodies. Economical losses due to replacement costs and cumbersome problems of replacement work have occurred.

이러한 문제점을 보완하기 위해 공개특허 10-2009-0122664호와 같이 여러가닥의 실을 엮어 이루어진 줄을 예초기에 결합된 회전판에 결합하여 줄로 하여금 예초기의 절단부재로 구성하여 작업안정성이 확보된 예초작업을 도모하였다.In order to compensate for this problem, as shown in Korean Patent Publication No. 10-2009-0122664, by combining the strings of several strands to the rotating plate coupled to the mowing machine to make a mowing work to ensure the work stability by forming a cutting member of the mower It was planned.

하지만 상기 공개특허 10-2009-0122664호의 줄은 회전판의 형성된 고정링에 의해 회전판과 결합이 이루어졌으나 상기 고정링은 회전판의 일측에 형성되어 항상 팽팽한 상태를 유지하지 못하는 줄을 수용하기가 쉽지 않으며 또한 줄을 회전판의 일측에 묶은 뒤 고정링에 줄을 관통시켜는 형태로 이루어지기 때문에 줄을 묶는 작업이 필수적으로 수행되어야하는 번거로움이 있으며 예초작업 중에 회전판에 묶은 줄이 풀려 작업의 효율성이 떨어지는 단점이 있어왔다.However, the string of the Patent Publication No. 10-2009-0122664 is made of the rotating plate by a coupling ring formed of the rotating plate, but the fixing ring is formed on one side of the rotating plate is not easy to accommodate the line that does not always maintain a tight state Since the string is tied to one side of the rotating plate and the fixing ring penetrates the string, there is a need to tie the string. This has been.

상기한 문제점을 해소하기 위해 안출된 본 발명의 목적은, 예초기와 결합되는 회전판의 양측으로 절단체의 후측이 고정되는 고정체를 각각 구성함으로써, 상기 회전판에 절단체의 교체 및 고정이 용이하게 이루어지면서도 절단체과 고정체의 결합 상태가 견고해져 예초작업 중에 절단체가 이탈되는 현상을 방지하여 예초작업의 편리함을 도모하는 예초용 커터를 제공함에 있다.An object of the present invention devised to solve the above problems, by configuring the rear side of the cutting body is fixed to both sides of the rotary plate coupled to the mowing machine, respectively, the replacement and fixing of the cutting body to the rotating plate made easy It is to provide a mowing cutter for the convenience of mowing work by preventing the phenomenon that the cutting body is detached during mowing work while being firmly coupled to the cutting body and the fixed body.
