履带式螺旋清仓机的研发

Research and Development of the Crawler-type Sweeping Auger

在分析我国浅圆仓现有清出仓技术装备的基础上,结合我国浅圆仓现有清出仓方式研发了浅圆仓的新型配套清仓装备—履带式螺旋清仓机。该设备采用履带式行走驱动装置,可有效解决驱动装置在薄粮层上行走出现打滑的问题,减少行走装置对粮食的破损。同时采用PLC变频控制系统,可实现履带式螺旋清仓机的自动化、无人化作业。经数次试验表明,该设备能有效完成浅圆仓余粮的清出仓作业,大幅提高粮食的清仓效率,清出仓作业产能可达300 t/h,具有良好的产业化应用前景。

A new type of clearance equipment that the crawler-type sweeping auger of the squat silo was developed on the basis of the unloading technical equipment of our country combined with the existing sweeping uploading methods for the squat silo. The crawler-type sweeping auger can effectively solve the problem of slipping on the thin grain layer and reduce the damage of the grain by using the crawler type walking device. Furthermore, using the PLC frequency control system can realize the automatic operation of the sweeping auger in the squat silo. Several tests on the product showed that it can effectively complete the uploading sweeping operation of the surplus grain in the squat silo, and greatly improve the efficiency of the clearance with the unloading capacity up to 300 t/h. The crawler-type sweeping auger has a good prospect of the practical applications of industrialization.
