The invention discloses a rotary drive mechanism for an unloading device of a fork loader. The unloading device of the fork loader comprises a front mounting plate, a rear mounting part and a pallet fork part, wherein the pallet fork part is connected at the front mounting plate; the rotary drive mechanism comprises an oil cylinder mechanism, a rack, an inner fixed column and an outer gear ring; the oil cylinder mechanism is provided with two oil cavities and a control mechanism for controlling the oil cavities to charge and discharge oil; the two ends of the rack are separately connected to the two oil cavities for controlling the two oil cavities to charge and discharge oil for driving the rack to slide; the rack is engaged with the outer gear ring; the outer gear ring and the front mounting plate are fixedly connected; and the inner fixed column is fixedly arranged on the rear mounting plate. The rotary drive mechanism has the advantages that: firstly, the two oil cavities charge and discharge oil for driving the rack to slide, the rack slides to drive the outer gear ring to rotate to drive the front mounting plate to rotate, generated driving moment is great, and materials withgreater viscosity can be smoothly unloaded from a 20ft container more strictly, so that the container is perpendicular to the ground, and realizes a bulk cargo loading function; and secondly, the front mounting plate is directly fixed to the outer gear ring, so that drive force is great, components are fewer, and the structure is simple and compact.

    本发明公开了叉装机卸货装置的旋转驱动机构,该叉装机卸货装置包含前安装板、后安装板和货叉部分,该货叉部分装接在前安装板;该旋转驱动机构包括油缸机构、齿条、内固柱和外齿圈,该油缸机构具有两油腔和控制油腔进出油的控制机构,该齿条两端分别连接两油腔以通过控制两油腔进出油驱动齿条滑动,该齿条和外齿圈啮合,该外齿圈和前安装板固定连接,该内固柱固设在后安装板上。它具有如下优点:一、通过两油腔进出油驱动齿条滑动,通过齿条滑动驱动外齿圈转动,驱动前安装板转动,产生的驱动力矩大,以能满足更加严格的粘度较大的物料从20ft集装箱顺利卸出,能实现将集装箱垂直于地面,实现散货装货的功能;二、前安装板和外齿圈直接固定,驱动力大,零部件少,结构简单、紧凑。
