연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

Disclosed herein is an apparatus preferably coupled to a boom on a truck which can simultaneously trim and chemically treat trees or other vegetation with a herbicide. The apparatus, in addition to have a standard saw blade assembly with limb clamping jaws, includes a sprayer assembly. The sprayer assembly includes nozzles which administer herbicides or other chemical treatments adjacent to the saw blades, allowing herbicide to be precisely administered to the tree limbs as they are cut.

The apparatus of claim 11, wherein the sprayer assembly further comprises at least one second nozzle formed on a side of the elongated saw arm. 13. The apparatus of claim 12, wherein the sprayer assembly further comprises two second nozzles formed on a side and proximate the ends of the elongated saw arm. 14. The apparatus of claim 13, wherein the saw blades appear on the same side of the elongated saw arm as do the second nozzles. 15. The apparatus of claim 14, wherein the second nozzles pop up beyond the side of the elongated saw arm when activated. 16. The apparatus of claim 11, wherein the saw blades are located on one side of the elongated saw arm. 17. The apparatus of claim 11, further comprising at least one channel formed within the elongated saw arm to pass the chemical treatment to the sprayer assembly. 18. The apparatus of claim 17, wherein the elongated saw arm comprises two pieces with the channel formed or milled therein. 19. The apparatus of claim 17, wherein the elongated saw arm comprises a single piece of material and wherein the channel is milled thereinto. 20.
