The invention relates to a rice-field seedling raising machine. Clamping tooth structures, which can be mutually in meshing transmission and can enable a driven ring at the quick rotation side to be separated from a driving ring when a left driven ring and a right driven ring have a certain rotation speed difference, are arranged between the driving ring and the left driven ring and between the driving ring and the right driven ring; only the clamping tooth structures need to be arranged on the driving ring and the driven ring; with the help of pressure of left and right auxiliary springs, thedriving ring and the driven ring are tightly combined; furthermore, the driven ring at the quick rotation side is separated from the driving ring when the left driven ring and the right driven ring have too high rotation speed difference due to slipping or hanging of a rotating wheel; but, the driven ring, which does not slip or hang, is meshed with the driving ring more tightly; the machine hasthe advantages of being simple in structure, smart in design, convenient to use, reliable to work, long in service life and the like; and, when the machine is driven on a hanging or slipping road surface, the slipping idle problem of the rotating wheel is well solved.

    本发明一种秧田育秧机在主动环与左从动环之间、主动环与右从动环之间设有能够相互啮合传动并在左从动环和右从动环存在一定转速差时使快转侧的从动环与主动环相脱离的卡齿结构,仅需在主动环和从动环上设置卡齿结构,借助左右辅助弹簧的压力使主动环和从动环紧密结合,并在左从动环和右从动环之间因转动轮打滑或悬空而存在过大的转速差时使快转侧的从动环与主动环相脱离,而未打滑或悬空一侧的从动环与主动环啮合更加紧密,具有结构简单、设计巧妙、使用方便、工作可靠和使用寿命长等优点,在悬空或打滑路面行驶时,很好地解决了转动轮打滑空转问题。
