Description
본 발명은 굴삭기용 톤백 인양 절개장치에 관한 것으로, 더욱 상세하게는 클램프가 형성된 굴삭기의 암대에 장착되어, 제설제 등의 입상의 충진물이 충진된 고하중의 톤백을 투하지점으로 거상 인양한 다음, 상기 인양된 톤백의 하부를 절개하여 톤백에 수납된 충진물을 적재함 등의 투하지점에 안전하게 투하하는 굴삭기용 톤백 인양 절개장치에 관한 것이다.The present invention relates to a ton bag lifting and cutting device for an excavator, and more specifically, to a ton bag lifting and cutting device for an excavator, which is mounted on the arm of an excavator with a clamp formed, and lifts and lifts a highly loaded ton bag filled with granular fillers such as snow removers to the dropping point, The present invention relates to a ton bag lifting and cutting device for an excavator that cuts the lower part of the lifted ton bag and safely drops the filler material contained in the ton bag onto a loading point, etc.
일반적으로 톤백이라는 것은 1톤 이상의 내용물을 담는 포대를 의미하는 것으로서, 통상 곡물류도 이러한 톤백에 담아서 인양하거나 보관할 때 이용하게 된다.In general, a ton bag refers to a bag containing more than 1 ton of contents, and grains are usually put in such ton bags and used for lifting or storage.
이러한 톤백에는, 각종의 곡물이 수납되기도 하고, 소금이나 염화칼슘과 같은 제설용 제설제도 톤백에 담긴 상태로 창고에 보관하였다가 필요시에 사용하게 된다.In these tone bags, various grains are stored, and snow removal agents such as salt or calcium chloride are stored in the warehouse in the tone bag and used when necessary.
이때, 제설제가 담긴 톤백은 인부가 들 수 없는 상당한 중량을 가지기 때문에 호이스트를 이용하여 제설차량의 적재함으로 옮겨서 개봉하여 톤백에 있는 제설제가 제설차량에 적재하고 있다.At this time, since the ton bag containing the snow removal agent has a considerable weight that workers cannot lift, it is moved to the loading compartment of the snow removal vehicle using a hoist, opened, and the snow removal agent in the ton bag is loaded into the snow removal vehicle.
그러나, 이때 인부가 제설차량의 적재함에 상차하여 톤백의 하단부를 낫이나 칼과 같은 도구를 이용하여 일일이 수작업으로 절개하여 개봉 되게 함으로써 매우 번거롭고 불편한 문제점이 있을 뿐만 아니라, 인부가 톤백을 수작업으로 절개할 때 톤백 하단부를 절개하기 때문에 상당한 낙하하중을 받고 있는 제설제가 순간적으로 쏟아지게 되므로 매우 위험하고 안전사고가 발생 되는 등의 문제점이 있다.However, at this time, there is a very cumbersome and inconvenient problem as the worker loads the snow removal vehicle into the loading box and manually cuts the lower part of the ton bag to open it using a tool such as a sickle or knife. In addition, there is a very cumbersome and inconvenient problem in that the worker has to manually cut the ton bag. Since the lower part of the tone bag is cut, the snow remover that is under a significant falling load is instantly poured out, which is very dangerous and has problems such as safety accidents.
그리고, 톤백 개봉시에 먼지나 분진이 발생 되기 때문에 인체에 유해한 문제점이 야기된다.Also, when opening the tone bag, dust or dust is generated, which causes problems harmful to the human body.
한편, 선행기술에 있어서는 톤백 하단부를 절개하는 장치가 대한민국 등록특허공보 등록번호 제10-0504326호에 의해 개시되었으나, 이는 절단장치가 레일 위에서 인양하면서 톤백을 절단하도록 된 것이기 때문에 장치가 복잡할 뿐만 아니라 레일이 설치된 부분에 의해서 한 장소에 고정되게 설치되어 사용되는 것이기 때문에 시설면적을 많이 차지하게 되는 등의 문제점을 수반하고 있다.Meanwhile, in the prior art, a device for cutting the lower part of the tone bag was disclosed by Korean Patent Publication No. 10-0504326, but since the cutting device is designed to cut the tone bag while lifting it on a rail, the device is not only complicated, but also complicated. Since it is fixedly installed and used in one place depending on the part where the rail is installed, it is accompanied by problems such as taking up a lot of facility space.
그리고, 톤백의 테두리 부분을 절단하는 장치가 대한민국 등록특허공보 등록번호 제10-1080204호로 개시되었으나, 이는 구조가 복잡하여 제조원가가 많이 소요되고 고장 우려성이 높은 문제점이 발견되었다.In addition, a device for cutting the edge of a tone bag was disclosed in Korean Patent Publication No. 10-1080204, but it was found to have a complex structure, require high manufacturing costs, and have a high risk of failure.
상기한 문제점을 해소하기 위해 안출된 본 발명의 목적은, 제설재 등의 충진물들이 충진된 톤백을 거상하여 적재함 등 투하지점의 상부로 인양한 다음, 상기 거상 인양된 톤백의 바닥을 절개하여 톤백에 충진된 충진물을 자중을 통해 투하지점에 투하함에 있어, 상기 톤백의 거상 인양과정에 거상된 톤백의 좌우 유동을 억제하여 톤백의 인양에 따른 안전성을 확보하고, 특히 절개과정에 상향 절입되는 절개날에 의해 톤백이 이탈하는 현상을 방지하여 향상된 절개 안정성을 갖도록 한 굴삭기용 톤백 인양 절개장치를 제공함에 있다.The purpose of the present invention, which was devised to solve the above problems, is to lift a ton bag filled with fillers such as snow removal materials to the upper part of the dropping point, such as a loading box, and then cut the bottom of the lifted ton bag and place it on the ton bag. When dropping the filled material to the drop point through its own weight, the left and right movement of the lifted ton bag is suppressed during the lifting and lifting process of the ton bag to ensure safety during the lifting of the ton bag, especially on the cutting blade that cuts upward during the cutting process. To provide a tone bag lifting and cutting device for an excavator that prevents the tone bag from coming off and has improved cutting stability.
