专利汇可以提供Rotating milking platform专利检索，专利查询，专利分析的服务。并且The present invention relates to a rotating milking platform for use in a milking parlor wherein the cows move onto a rotating platform, and the cows ride around on the platform while they are milked. A unique drive and support construction for the common friction individual stall portions of the platform which carries the cows is disclosed. The drive compensates for irregularities in the platform. In addition controls for regulating the entry and exit of the cows to and from the platform are provided. Also, means are provided on the platform to cleanse the interior side walls of the parlor as the platform rotates.，下面是Rotating milking platform专利的具体信息内容。
1.

2. The combination as specified in claim 1 wherein said pedestal means incluDe a rotatable wheel, a track means positioned on said floor and extending in a circle adjacent to the interior of said wall, said wheel engaging the upper surfaces of said track means, and guide means along the outer surfaces of said track means to prevent said rotatable wheel from slipping off said track means in direction toward the center of the parlor.
3. In a rotating milking parlor having a support floor, an upright wall at the periphery of said floor and having an interior surface, and an annular platform positioned adjacent the interior surface of said wall, said annular platform being made up of a plurality of individual stall sections, each having support means for a cow, each stall section having end members fixed to the adjacent stall sections to form said annular platform, each stall section being of size to support a single cow, pedestal means mounted on and positioned below each stall section and having movable support means mounted thereon to permit movement of said annular platform with respect to said floor in a circular path, and an operator support platform member mounted on said annular platform and supported from each of said stall sections on a side thereof toward the center of rotation of said platform and being positioned substantially below the surface of said support means for the cow on each of said stall sections.
4. The combination specified in claim 3 wherein said floor includes an offset section adjacent the inner edges of said operator platform members, said offset section permitting the upper surface of said operator platform members to be substantially on a level with the floor extending inwardly toward the center of the building from said operator platform member.
5. A rotating milking platform having surfaces for supporting cows thereon, means to support said platform for rotation about a substantially upright axis, means to drive said annular platform comprising a depending flange fixed to the periphery of said annular platform and having a first surface generally parallel to the axis of rotation of the annular platform, power means comprising a drive wheel, and a pressure backup wheel means, means to mount said drive wheel in position with the periphery thereof engaging said first surface of said depending flange and including a first member, means between said first member and said pressure wheel means to mount said pressure wheel means to engage a surface of said flange opposite from the first surface, means to resiliently urge said pressure wheel means against said opposite surface of said flange, said pressure wheel means and said drive wheel being mounted on a common drive member, and means to pivotally mount said common drive member independently of said annular platform about an axis substantially parallel to said upright axis to permit said common member to move about its axis to accommodate changes in the position of said depending flange as the platform rotates.
6. A rotating milking parlor comprising a power driven rotating platform, a plurality of cow stalls on said platform, a building wall surrounding said platform, said stalls having an open side facing said wall, an entry opening and an exit opening defined in said building wall, an exit door mounted on said wall for movement to and from a normally closed position blocking said exit opening, means providing a signal indicating that a stall is positioned in a desired relationship to the exit opening as the platform rotates, and control means responsive to said signal to open said exit door.
7. The combination of claim 6 and manual operable means to disable said means providing a signal while permitting said platform to continue to rotate.
8. The combination as specified in claim 6 and entry door means mounted adjacent said entry opening and movable to position to close said entry opening, and control means to move said entry door means to its closed position.
9. The combination as specified in claim 6 wherein said signal means comprises a position inDicator on each stall, and a device responsive to said position indicator mounted adjacent said platform on said building wall.
10. A milking parlor comprising a rotating platform, a plurality of cow stalls on said platform, an entry opening to permit entry of cows onto said platform, a plurality of preparation stalls positioned with respect to said milking parlor adjacent said entry opening, said preparation stalls each being adapted to hold a cow for preparation for milking, exit gate means for each preparation stall, separate actuator means to open each of said exit gate means, and means to provide a signal indicating a cow stall on said platform is adjacent the entry opening and to operate one of said actuator means to open said exit gate means for one of said preparation stalls, said means to provide a signal including means to sequentially open the exit gate means of the preparation stalls.
11. The combination as specified in claim 10 wherein said means providing a signal to open the exit gate means of said preparation stalls is timed so that the rotationally leading end of a cow stall on the rotating platform has moved past the entry opening when a cow released from a preparation stall reaches the entry opening, and wall means positioned to define a relatively narrow entry opening and extending on a substantially radial line from the rotating platform whereby a cow stepping onto the platform turns a corner to move her rear quarters toward an inner side of said cow stall.
12. The combination as specified in claim 10 and entry door means movable to a closed position to close the entry opening, and means to interrupt operation of said exit gate actuator means when the entry door is closed.
13. The combination as specified in claim 10 wherein said means to provide a signal comprises a first portion carried by each cow stall on said platform and a second portion stationarily mounted on a portion of said milking parlor.
14. The combination as specified in claim 13 wherein said first portion comprises a magnet and said second portion comprises a magnetically actuated switch.
15. In a rotating milking parlor including a platform having surfaces for supporting cows thereon, and forming a continuous platform for supporting said cows and having means to support said platform for rotation about an upright axis, the improvement comprising drive means for said platform including a depending peripheral flange attached to said platform, an arm member, means to pivotally mount said arm member for movement transverse to said flange, a drive wheel mounted on said arm member in position to frictionally engage said flange, at least one back-up wheel on the opposite side of said flange from said drive wheel, means to resiliently mount said back-up wheel with respect to said drive wheel to urge said back-up wheel toward said drive wheel and to resiliently capture said flange between said back-up wheel and said drive wheel, and power means to carry power to said drive wheel as said arm pivots.
16. The combination specified in claim 15 wherein said power means comprises a shaft, said shaft forming a pivot shaft for said arm and a power shaft, and power drive means drivably extending from said shaft to said drive wheel.
17. The combination of claim 15 and a wall member surrounding said platform, said wall member having an opening therethrough, stall means on said platform, said stall means having an open side facing said wall means whereby cows entry and exiting relative to said platform occurs when the stall means align with said opening as said platform is rotating.
18. The combination of claim 15 and means to control the speed of rotation of said drive wheel.
19. The combination of claim 18 and means to indicate the relative speed of rotation of said platform.
20. The combination of claim 17 wherein said opening is divided into an entry opening and an exit opening, door means to normally close said exit opening, means to deliver a signal when a stall on said platform is positioned adjacent said exit opening, and control means responsive to said signal to cause opening of said exit door means.
