The invention belongs to the field of measuring friction characteristics of granular materials, and particularly relates to a sliding friction angle measuring instrument for the granular materials. The sliding friction angle measuring instrument mainly comprises a tilting mechanism, a fixing bolt, a hinge, a supporting mechanism and an angle measuring mechanism. The supporting mechanism includes ascrew rod, an adjusting nut, a fixing plate and an adjusting supporting foot. The angle measuring mechanism includes a protractor dial, a suspension wire and a pendant wire. The tilting mechanism includes a tilting panel and a plate fixing block. The sliding friction angle measuring instrument for the granular materials is characterized in that the hinge hinges the tilting mechanism and the supporting mechanism together, the tilting mechanism is located above the supporting mechanism, the angle measuring mechanism is fixed to the side face of the tilting mechanism by the fixing bolt, by the up and down movement of the adjusting nut on the screw rod, the tilting mechanism is driven to change the inclined angle, and the pendant wire is subjected to numerical reading at the final staying position of the protractor dial. The sliding friction angle measuring instrument for the granular materials is simple in structure, simple in operation, accurate and intuitive in measurement and high inreliability, and is suitable for continuous and repeated measurement.
Description
technical field [0001] The invention belongs to the field of friction characteristic measurement of granular materials, and in particular relates to a measuring instrument for sliding friction angle of granular materials. Background technique [0002] In the fields of granular material processing, transportation, and storage, the sliding friction angle inevitably exists between the granular material and the tool material, and has become one of the important parameters that must be considered in the design process of related mechanical products. Effective and reasonable use of the sliding friction angle between the granular material and the tool material can also greatly increase work efficiency, save energy and improve reliability. [0003] At present, there are few measuring instruments for the sliding friction angle of granular materials on the market. Some instruments involve the measurement of the sliding friction angle of granular materials, but most of them are not con...
