浅圆仓全液压智能螺旋清仓机优化设计

Optimization Design of Fully Hydraulic Intelligent Spiral Clearing Machine for Squat Silo

浅圆仓清仓作业存在粉尘防爆、粮食板结、人员作业环境恶劣等难题。开发了一种全液压智能螺旋清仓机,采用全液压驱动形式,液压泵站安装在筒仓及廊道外,筒仓内无电气元件,可解决20区粉尘防爆问题;采用恒功率控制技术,可自动调节螺旋的转速和扭矩值,非板结工况螺旋处于高转速低扭矩工作点,板结工况螺旋处于低转速高扭矩工作点,可同时满足板结和无板结2种工况;具有自动清仓功能,可自主完成清仓作业。

There are problems such as dust explosion-proof,grain compaction,and poor working environment of personnel in squat silo clearing operation.An all-hydraulic intelligent spiral clearing machine is developed,which adopts all-hydraulic drive form,the hydraulic pump station is installed outside the silo and corridor,and there is no electrical component in the silo,which can solve the problem of dust explosion-proof in 20 areas;constant power control technology is adopted,which can automatically adjust the rotational speed and torque value of spiral.and the spiral is at the high rotational speed and low torque working point in non-slabbing condition,while the spiral is at the low rotational speed and high torque working point in slating condition,so that it can satisfy the two working conditions of hardening and non-hardening at the same time;it has the function of autonomous clearing,and can complete the clearing operation independently.
