本筛砂机系由滚筛、刮板上料臂、调幅、皮带出料、出筛漏、回转和行走等主要零部件所组成(详见图1～图4)。一、特点1.吃料面广:自动摇臂角度可在0～120度范围内调整,形成一个扇子面,由一台0.5瓩电机驱动,经减速达到每分钟一转,同时每回转一次自动落臂3～5厘米。摇臂是靠晶体管时间继电器控制的(详见图5、图 The sand screening machine is composed of major components such as rolling screens, scraper arm, amplitude modulation, belt discharge, screen drain, rotation and walking (see Figure 1 to Figure 4 for details). First, the characteristics of 1. Features a wide range of materials: Automatic rocker arm angle can be adjusted within the range of 0 to 120 degrees, the formation of a fan surface, driven by a 0.5瓩 motor, after the deceleration to a turn per minute, while each time an automatic Falling arm 3 to 5 cm. The rocker arm is controlled by a transistor time relay (see Figure 5, figure)
