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 compost supplement spreader for delivering supplement to the top of an elongated compost pile comprising: a frame having spaced apart sides, each side having a top and a bottom portion; motive means carried by said frame; spaced apart wheels mounted on said bottom portion of each said frame sides, at least some of said wheels being operably connected to said motive means providing for movement of the frame upon the earth, at least some of said wheels being steerable whereby said frame may be guided along said elongated compost pile with said compost pile being received between said frame sides; an operator station on said frame having means to control said steerable wheels; a hopper having an open top, an open bottom and sidewalls; means elevationally supporting said hopper in said frame between said sidewalls, including means to lower said hopper to a loading position whereby supplement may be deposited in said open top of said hopper and means to raise said hopper to an upper operating position; conveyor means that substantially closes said hopper bottom with a clearance therebetween; means to controllably discharge supplement from said hopper bottom by said conveyor means; and means when said hopper is elevationally positioned whereby said hopper bottom and said conveyor means clears the top of said compost pile. 2. A compost supplement spreader according to claim 1 including means to positionally stabilize said hopper within said frame as said hopper is moved from a lower to a higher elevation and vice versa. 3. A compost supplement spreader according to claim 2 wherein said means to positionally stabilize said hopper includes: a first and a second parallelled, spaced apart elongated horizontal shaft rotatably supported to said hopper; two spaced apart sprockets affixed adjacent each end of each of said shafts providing a sprocket affixed to each shaft in four vertical planes; four chains, one in each of said vertical planes, one end of each chain being affixed to said frame at an elevationally high position in a said plane and the other end being affixed to said frame at an elevationally low position, each chain looping over the top of a said sprocket affixed to one of said shafts and under the bottom of a said sprocket affixed to the other of said shafts, there being thereby a sprocket affixed to each said shaft and a chain in each of said four vertical planes whereby said hopper is stabilized in horizontal planes within said frame as said hopper is moved from a lower to a higher elevation and vice versa. 4. A compost supplement spreader according to claim 1 wherein said means to discharge supplement includes: spaced apart rollers and mounting means therefor supported to and below said hopper; said conveyor means comprising a wide, endless belt supported on said spaced apart rollers, the belt extending beneath and spaced from said hopper open bottom providing a clearance therebetween, the belt normally closing the open bottom against the discharge of supplement; and means of applying rotational energy to at least one of said rollers to cause said belt to rotate and thereby controllably discharge supplement from said hopper. 5. A compost supplement spreader according to claim 1 including: hydraulic cylinder-piston means carried by said frame; and structural connection between said hydraulic cylinder-piston means, and said hopper providing said means to raise and lower said hopper. 6. A compost supplement spreader for delivering supplement to the top of an elongated compost pile comprising: a frame having spaced apart sides, each side having a top and a bottom portion; motive means carried by said frame; spaced apart wheels mounted on said bottom portion of each said frame sides, at least some of said wheels being connected to said motive means providing means for movement of said frame upon the earth and along said elongated compost pile with said compost pile being received between said frame sides; a hopper having an open top, an open bottom and sidewalls; means elevationally supporting said hopper in said frame between said sidewalls, including means to lower said hopper to a loading position whereby supplement may be deposited in said open top of said hopper and means to raise said hopper to an upper operating positioning whereby said hopper bottom clears the top of a compost pile; means to controllably discharge supplement from said hopper bottom; a first and a second paralleled, spaced apart elongated horizontal shaft rotatably supported to said hopper; two spaced apart sprockets affixed adjacent each end of each of said shafts providing a sprocket affixed to each shaft in four vertical planes; and four chains, one in each of said vertical planes, one end of each chain being affixed to said frame at an elevationally high position in said plane and the other end being affixed to said frame at an elevationally low position in the same said plane, each chain looping over the top of a said sprocket affixed to one of said shafts and under the bottom of a said sprocket affixed to the other of said shafts, there being thereby a sprocket affixed to each said shaft and a chain in each of said four vertical planes providing means to positionably stabilize said hopper in horizontal planes within said frame as said hopper is moved from a lower to a higher elevation and vice versa. 7. A compost supplement spreader according to claim 6 wherein said means to controllably discharge supplement includes: spaced apart rollers and mounting means therefor supported to and below said hopper; a wide, endless belt supported on said spaced apart rollers, the belt extending beneath and spaced from said hopper open bottom providing a clearance therebetween, the belt normally closing the open bottom against the discharge of supplement; and means of applying rotational energy to at least one of said rollers to cause said belt to rotate and thereby controllably discharge supplement from said hopper. 8. A compost supplement spreader according to claim 6 including: hydraulic cylinder-piston means carried by said frame; and structural connection between said hydraulic cylinder-piston means and said hopper providing said means to raise and lower said hopper.
