摘　　要：深槽型带式输送机主要用于输送倾角大的物料。运用散体力学方法从理论上证明深槽型带式输送机具有增大物料输送倾角的能力。通过对由四托辊组成的双排V型深槽型托辊组的最大物料截面进行理论分析,推导出输送带上允许的最大物料横截面积的计算公式。由MATLAB软件编程得到物料截面积最大时,其托辊组的最佳布置型式为双V型四托辊组的结构设计提供参考和理论依据。Belt conveyor with deep groove is mainly used for conveying materials with large inclination angle. The mechanics of granular media method has been used to prove theoretically that the belt conveyor with deep groove has the ability to increase the inclination of material conveying. Based on the theoretical analysis of the maximum material cross-section of the double row V-shaped deep groove roller group composed of four idlers, the formula for calculating the allowable maximum material cross section area on the conveyor belt has been derived. When the cross-section area of material has been set to be maximized by MATLAB software programming, the optimum arrangement of supporting rollers can provide reference and theoretical basis for the structural design of double V-shaped and four supporting rollers.
