一种茶青筛分机

Tea green screening machine

Abstract

The invention relates to a tea green screening machine. The tea green screening machine comprises a hopper, an electric valve arranged on a discharging opening in the bottom of the hopper, a screening frame arranged below the discharging opening, an upper screen net and a lower screen net, wherein the upper screen net and the lower screen net are vertically arranged on the screening frame; the size of meshes of the upper screen net is suitable for screening out leaves and leaf stems with the length larger than 3cm, and the size of meshes of the lower screen net is suitable for screening out leaves and leaf stems with the length larger than 0.5 cm; a rotating arm is arranged below the left end of the screening frame, one end of the rotating arm is connected with a bearing at the end of a transmission shaft, and the other end of the rotating arm is fixedly connected to an output shaft of a motor; the transmission shaft is arranged at the bottom of the screening frame, and the bottoms of the two sides of the right end of the screening frame are in sliding fit with a pair of sliding rails distributed in a left and right manner through pulleys; when a control motor drives the rotating arm to rotate, the upper screen net and the lower screen net are suitable for left-and-right rapid displacement; and meanwhile, the left end of the upper screen net and the left end of the right screen net are suitable for vertical rapid displacement, and tea green of the upper screen net and the lower screen net can be rapidly screened.
本发明涉及一种茶青筛分机,茶青筛分机包括:料斗、设于料斗底部出料口上的电动阀,设于出料口下方的筛分框架,上下设于该筛分框架上的上、下筛网;上筛网的网孔大小适于筛分出长度大于3cm的叶片和叶茎;下筛网的网孔大小适于筛分出长度大于0.5cm的叶片和叶茎;筛分框架的左端下方设有转动臂,该转动臂的一端与一传动轴的端部轴承连接,该转动臂的另一端固定连接在一电机的输出轴上;传动轴设于该筛分框架的底部;筛分框架的右端两侧底部分别通过滑轮滑动配合于一对左右分布的滑轨上;当控制电机驱动转动臂转动时,上、下筛网适于左右快速位移,同时该上、下筛网的左端适于上下快速位移,使上、下筛网上的茶青实现快速筛分。
