Embodiment 1

[0022] Such as figure 1 , 2 Shown is a kind of crushed stone weak particle content test device of the present invention, comprises traveling wheel 1, cylindrical roller 2, miniature gantry crane 3, force frame 6, tray 4 and weight 8. The miniature gantry crane 3 includes a bottom bar and a vertical wall; the tray 4 is arranged on the upper surface of the force frame 6, and the weight 8 is placed in the tray 4; the traveling wheel 1 is fixedly installed on the miniature On the bottom rods on both sides of the gantry crane 3, the cylindrical roller 2 passes through the lower guide grooves of the vertical walls on both sides of the miniature gantry crane through the wheel shafts 11 on both sides, and the force applying frame 6 rides on the cylindrical roller through the bearing 5 2. On the axles 11 on both sides, the guide shaft 7 of the force applying frame 6 passes through the upper guide groove 9 of the vertical wall of the miniature gantry crane 3. A limiting block 10 is ar...

Embodiment 2

[0028] This embodiment is basically the same as Embodiment 1. For the brevity of description, in the description process of this embodiment, no longer describe the same technical features as Embodiment 1, only explain the difference between this embodiment and Embodiment 1:

Abstract

The present invention provides a detritus soft particle content testing apparatus. The apparatus comprises a road wheel, a cylindrical runner wheel, a miniature gantry crane, a force applying frame, atray and a weight. The tray is disposed on an upper surface of the force applying frame. The weight is disposed inside the tray. The road wheel is fixedly installed on a bottom rod on both sides of the miniature gantry crane. The cylindrical runner wheel passes through a lower guide slot of a vertical wall on both sides of the miniature gantry crane by using wheel spindles on both sides. The force applying frame is erected on the wheel spindles on both sides of the cylindrical runner wheel by using a bearing. A guide bearing of the force applying frame passes through an upper guide slot of the vertical wall of the miniature gantry crane. According to the detritus soft particle content testing apparatus provided in the present invention, detection efficiency is significantly improved, labour strength is reduced; pressure application is constant and accurate, and detection precision is high.

Description

technical field [0001] The invention relates to the technical field of material detection, in particular to a test device for the content of weak particles of gravel. Background technique [0002] Crushed stone is a commonly used engineering material. It is used for crushed stone in engineering structures. Its physical and mechanical properties have a direct impact on the quality of the project. According to the functional requirements of engineering structures, relevant standards and regulations have specific specifications for the physical and mechanical properties of crushed stones. Regulation. For aggregates used in railway subgrade engineering and highway engineering aggregates, the content of weak (soft, easily broken) particles is an important performance index of aggregates. [0003] For the detection of weak (soft, easily broken) particle content of crushed stones, the current test method in the railway industry is: firstly classify the inspected crushed stones acc...
