Embodiment Construction

[0009] like figure 1 As shown, the present invention includes a measuring board 1, an angle dial 2, a rotating shaft 3, a flexible rope 4 and a weight 5, wherein the angle dial 2 is arranged on the measuring board 1, and the zero degree line 6 of the angle dial 2 is connected to the measuring board 1. The measurement side 7 is vertical, and the rotating shaft 3 is located at the center of the zero degree line 6, and one end of the flexible rope 4 is connected with the rotating shaft 3, and the other end is connected with the weight 5. In order to make the measurement more intuitive, the angle dial 2 is made of transparent material, and adopts a left and right double range scale design. When measuring the angle of repose, make the measuring side 7 of the measuring board 1 of the present invention parallel or be placed on the inclined surface of the material 8 to be measured, and the angle of repose of the material can be intuitively measured by the indication of the flexible ro...

Abstract

The invention discloses a device for directly measuring the repose angle of material. The device comprises a measuring plate, an angle dial, a rotating shaft, a flexible rope and a heavy hammer, wherein the angle dial is arranged on the measuring plate; the zero line of the angle dial is perpendicular to one measuring edge of the measuring plate; the rotating shaft is arranged in the center of the zero line; and one end of the flexible rope is connected with the rotating shaft, and the other end of the flexible rope is connected with the heavy hammer. When the device is in use, the measuring edge of the measuring plate is kept parallel to or placed on the bevel of to-be-measured material, and thus the repose angle of the material can be visually measured through indication of the flexible rope on the angle dial.

Description

technical field [0001] The invention relates to a device for directly measuring the angle of repose of a material. Background technique [0002] The angle of repose, also known as the stacking angle, is a basic physical parameter and is the angle between the inclined plane and the horizontal plane when the material is stacked. The determination of the angle of repose is conducive to understanding the basic shape of the material, such as the relationship between the amount of material to be discharged, the belt speed and the angle of repose when the lead concentrate is conveyed by the belt, so as to determine the appropriate belt width; Altitude and angle of repose to estimate storage and more. At present, the methods for measuring the angle of repose at home and abroad mainly include injection method, discharge method and tilt method, etc., but the devices of these traditional measurement methods are too complicated, difficult to operate, and the measurement results are not...
