Abstract

The utility model discloses a drive cam used for a rice husking machine. The drive cam used for the rice husking machine comprises an annular cam body. A drive gear array composed of drive gears is arranged on the inner side wall of the cam body. A driven gear array composed of driven gears is arranged on the outer side wall of the cam body. A locking protruded array composed of locking protrusions is arranged on the upper portion of the cam body. The locking protrusions are evenly arranged on the periphery of the cam body. A scrap discharging slot is formed in the middle of each driven gear. The locking protruded array on the cam body is used. When the rice husking machine is stopped, a user can move the drive cam to a locking position of the drive cam, clamp the locking protrusions and thoroughly prevent the drive cam from accidentally rotating so as to improve safety of the rice husking machine. In addition, as the scrap discharging slot is formed in the middle of each driven gear, scraps can be rapidly blown out and the drive cam is prevented from slipping.
本实用新型公开了一种用于碾米机的驱动凸轮,所述的用于碾米机的驱动凸轮包含一环形的凸轮主体,所述的凸轮主体的内侧壁上设有由主动齿组成的主动齿阵列,凸轮主体的外侧壁上设有由被动齿组成的被动齿阵列,所述的凸轮主体的上部设有由锁止突出组成的锁止突出阵列,所述的锁止突出均匀地设置在所述的凸轮主体的周向上。所述的被动齿的中部设有出屑槽口。本实用新型的用于碾米机的驱动凸轮利用凸轮主体上的锁止突出阵列,当碾米机停机后,使用者可以将驱动凸轮移动到其锁止位置上,将锁止突出卡住,彻底防止驱动凸轮意外转动,提高了碾米机的安全性。另外,由于被动齿的中部设有出屑槽口,能快速将碎屑吹出,防止驱动凸轮发生打滑。
