Material hardness detection device based on multi-sensor fusion

Abstract

The invention provides a material hardness detection device based on multi-sensor fusion, and relates to the field of continuous hardness detection for coal mines. The device comprises a first screening hopper, a second screening hopper, a material pushing mechanism and a detection mechanism which are sequentially connected in series through a conveying belt, wherein beating mechanisms are arranged on the conveying belt between the first screening hopper and the second screening hopper and between the second screening hopper and the material pushing mechanism, the first screening hopper and the second screening hopper are each provided with a measuring mechanism used for measuring the shape of a material, the first screening hopper and the second screening hopper screen the material according to data obtained by the measuring mechanisms, the beating mechanisms are used for beating the screened material to adjust the shape of the material, and the material pushing mechanism is used for pushing the material into the detection mechanism for hardness detection. According to the invention, by measuring the shape of a flat material and correcting the shape of the material in combination with multi-stage beating, the shape meeting the strength measurement requirement is achieved, the continuous sorting, correcting and strength measurement process of the material is achieved, and the requirement for frequently measuring the hardness of a working face rock mass in the tunneling process is met.

Description

technical field [0001] The disclosure relates to the field of continuous hardness detection for coal mines, in particular to a material hardness detection device based on multi-sensor fusion. Background technique [0002] In the process of establishing tunnels and roadways in coal mining, the rock soil or coal seam characteristics of the excavation position of the working equipment directly affect the selection of the construction plan. The hardness parameter of the rock mass is one of the important indicators of rock-soil properties, and it needs to be measured frequently during the excavation process. The hardness data of the rock mass at the excavation location is used as a reference for the adjustment of the construction plan to ensure the effectiveness and safety of the construction. [0003] In the process of excavating through large-scale excavation equipment, it is often selected to sample the rock mass of the excavation surface, and measure and record the hardness o...

Problems solved by technology

[0003] In the process of excavating through large-scale excavation equipment, it is often selected to sample the rock mass of the excavation surface, and measure and record the hardness of the sample after a certain working time or a certain working distance; the working space of the hardness measuring equipment The range of accommodation is limited, and too large or too small a sample will affect the accuracy of the measurement. Therefore, it is necessary to select a sample that meets the hardness testing equipment before the measurement, and this screening process often needs to be carried out manually by the staff, and the efficiency is low; and through the machine When visually cooperating with the mechanical arm to select samples, limited by the narrow space of excavation equipment such as shield machines, the movement of the mechanical arm is likely to interfere with the outside, and in the process of moving a large amount of materials, materials in various postures Mixing and continuous movement, the success rate of machine vision screening is low, and it is difficult to meet the needs of material hardness testing
