연합인증

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.

1. A garden screening device for sifting and separating unwanted soil debris material from valuable soil material, comprising:a movable carriage assembly having a pair of wheels providing for the movement of the carriage assembly on the ground surface; a triangular-shaped framework mounted to the carriage assembly and extending upwardly therefrom; a screening drum pivotally mounted to the framework so that the screening drum can pivot 180 degrees between a material screening position and a material dump position; the screening drum capable of rotation on the framework for sifting and screening valuable soil material from debris material; a soil slide mounted on the framework adjacent the material screening position of the screening drum; means to selectively rotate the screening drum so that valuable soil material is sifted and separated from debris material; a manually operable handle interconnected to the screening drum for selectively pivoting the screening drum between the material screening position and the material dump position; and rotation of the screening drum when the screening drum is in the material screening position sifts and separates the valuable soil material from the debris material so that the valuable soil material passes through the screening drum and falls onto the slide for conveyance down the slide and collection on the ground while the debris material is contained within the screening drum, and manually pivoting the screening drum to the dump position allows for the dumping of the debris material on the ground at a location that is separate from the location of the valuable soil material. 2. The garden screening device of claim 1 wherein the screening drum includes a mixing end and an opposite wide-mouth outlet end to facilitate the loading and dumping of the soil material.3. The garden screening device of claim 2 wherein the screening drum includes non-cylindrical shapes for enhancing the circulation and disturbance of the soil material within the screening drum to improve the sifting and separating of the debris soil material from the valuable soil material.4. The garden screening device of claim 3 wherein the screening drum includes a plurality of vanes mounted to the screening drum and extending within the interior of the drum for enhancing the circulation and mixing of the soil material to improve the sifting and separation of the debris soil material from the valuable soil material.5. A garden screening device for sifting and separating debris material from valuable soil material, comprising:a portable carriage assembly having a pair of wheels allowing for the movement of the carriage assembly on the ground; a triangular-shaped framework mounted to the carriage assembly and extending upwardly therefrom; a screening drum pivotally mounted to the framework so that the screening drum can pivot 180 degrees between a material screening position and a material dump position; the screening drum including a mixing end and an opposite wide-mouth outlet end for facilitating the loading therein and dumping therefrom of the material; the screening drum capable of rotation on the framework for sifting and separating the valuable soil material from the debris material; a slide mounted on the framework adjacent the material screening position for conveying the valuable soil material down to the ground; means to selectively rotate the screening drum so that the valuable soil material is sifted and separated from the debris material by gravity and the continuous rotation of the screening drum; a manually operable handle interconnected to the screening drum for selectively pivoting the screening drum between the material screening position and the dump position; and the continuous rotation of the screening drum causing the sifting and separation of the debris material from the valuable soil material so that the valuable soil material passes through the screening drum and falls onto the slide for conveyance down the slide to collection on the ground while the debris material remains within the screening drum whereupon halting the rotation of the screening drum and manually pivoting the handle causes the screening drum to pivot to the dump position resulting in the dumping of the debris material on the ground and at a location that is separate from the location of the valuable soil material. 6. The garden screening device of claim 5 wherein the screening drum includes non-cylindrical shapes for enhancing the circulation and disturbance of the soil material within the screening drum thereby improving the sifting and separation of the debris material from the valuable soil material.7. The garden screening device of claim 6 wherein the screening drum includes a plurality of vanes mounted to the screening drum and projecting within the interior of the screening drum for enhancing the circulation and mixing of the soil material thereby improving the sifting and separation of the valuable soil material from the debris material.8. A garden screening device for sifting and separating valuable soil material from debris material, comprising:a movable carriage assembly having a pair of wheels allowing for the movement of the carriage assembly on the ground; a triangular-shaped framework mounted to the carriage assembly and extending upwardly therefrom; a screening drum pivotally mounted to the framework so that the screening drum can pivot 180 degrees between a material screening position and a material dump position; the screening drum including a mixing end and an opposite wide-mouth outlet end for facilitating the loading and dumping of the material; a slide mounted on the framework adjacent the material screening position for conveying the valuable soil material down to the ground for collection thereon; means to selectively rotate the screening drum so that the valuable soil material is sifted and separated from the debris material by gravity and the continuous rotation of the screening drum; a manually operable handle interconnected to the screening drum for selectively pivoting the screening drum between the material screening position and the dump position; the drum including a plurality of vanes projecting into the interior of the drum to enhance the circulation and mixing of the material; and the continuous rotation of the screening drum causing the sifting and separation of the debris material from the valuable soil material so that the valuable soil material passes through the screening drum and falls onto the slide for conveyance down the slide to collection on the ground while the debris material remains within the screening drum whereupon halting the rotation of the screening drum and manually pivoting the handle causes the screening drum to pivot to the dump position resulting in the dumping of the debris material on the ground and at a location that is separate from the location on the ground of the valuable soil material. 9. The garden screening device of claim 8 wherein the screening drum includes non-cylindrical shapes for enhancing the circulation and disturbance of the material within the screening drum thereby improving the sifting and separation of the valuable soil material from the debris material.
