Rake With Stripping DeviceTwo design concepts for a RAKE with a device to remove easily off the raked up material, like grass or foliage.A request by a family member and an inspiration resp. small challenge for me.The animation has been done for "Version B" without showing the actuating compression spring, because I don't know how to animate a compression spring in «KeyShot 4».But I want to show the function of the stripping device.Notes:Stripping device:Material: Aluminium for all components, without the compresson spring and screwsCompesssion spring: Spring steelScrews: SteelComplete moving mass of the stripping device "Version B": approx. 1.65 kgComplete moving mass of the stripping device "Version C": approx. 1.2 kgCompression spring for "Version B" (calculated):Material: Spring steelDm = 15.5 mmd = 1.8 mmDi = 13.7 mmDa = 17.3 mmNumber of spring coils: see 3D modelL0 =115 mmL1 = 106 mmL2 = 30 mmWorking stroke = 76 mmc = 1.915 N/mmCompression spring for "Version C" (calculated):Material: Spring steelDm = 17.8 mmd = 1.3 mmDi = 16.5 mmDa = 19.1 mmNumber of spring coils: see 3D modelL0 =115 mmL1 = 91.2 mmL2 = 15.2 mmWorking stroke = 76 mmc = 0.516 N/mmThread for handle attachment: M30 x 3.0Thread for comb attachment : M6The models are available as STEP files (.stp) only.
