Problems solved by technology

However, the existing rod-shaped material accumulation angle side wall collapse test device is relatively simple, the degree of automation is not high, too much manual intervention is time-consuming and labor-intensive, and the accuracy of the results will be more or less affected by manual intervention, such as When pulling away from one side of the wall by hand, the speed, angle, and force will be different every time, resulting in the state of the material when it collapses is different each time, which will affect the accuracy of the final accumulation angle.
At the same time, the existing rod-shaped material accumulation angle side wall collapse test device can only test materials of a single length specification, and cannot be adjusted when the material length changes. high, long period

Abstract

The invention discloses a rod-shaped material accumulation angle side wall collapse test device. A right door plate is driven by an air cylinder to be opened and closed, a rear wall plate is driven by a driving mechanism to do front-back horizontal linear motion, and rod-shaped materials are stacked in a space formed by the wall plates and the right door plate in the closed state in the direction perpendicular to a front wall plate; a driving mechanism is adjusted to drive the front wall plate to horizontally move back and forth in the length direction of the rod-shaped materials, so that the distance between the rear wall plate and the front wall plate is slightly larger than the length of the rod-shaped materials, an air path is switched on, the air cylinder is started to open the right door plate connected to the air cylinder, and the rod-shaped materials originally stacked in a static state are instantly poured onto a bottom plate. The invention further discloses a rod-shaped material accumulation angle side wall collapse test method. According to the invention, natural accumulation of the rod-shaped materials and formation of the accumulation angle can be rapidly and conveniently realized, and the measured accumulation angle can improve the accuracy of simulation analysis of motion characteristics of the rod-shaped materials.

Description

technical field [0001] The invention relates to an automatic detection technology, in particular to a device and method for a side wall collapse test of a rod-shaped material accumulation angle. Background technique [0002] The slope of the stockpile (that is, the angle between the stockpile and the ground) when the material is naturally accumulated is called the accumulation angle, also known as the angle of repose and the angle of repose. The packing angle is related to the material density, surface area, shape and the coefficient of friction of the material. The measured material accumulation angle data can be used in the simulation of material movement characteristics in discrete element analysis software. [0003] Most of the current material accumulation angle test methods and testing equipment are only suitable for the determination of the accumulation angle of granular materials. [0004] For the accumulation angle of rod-shaped or strip-shaped materials such as c...
