Material hardness detection device based on multi-sensor fusion

Abstract

The disclosure provides a material hardness detection device based on multi-sensor fusion, which relates to the field of continuous hardness detection for coal mines, including a first sieve bucket, a second sieve bucket, a pushing mechanism and a detection mechanism connected in series through a conveyor belt, the first A beating mechanism is provided on the conveyor belt between the sieve bucket and the second sieve bucket, and between the second sieve bucket and the pushing mechanism; the first sieve bucket and the second sieve bucket are equipped with The first sieve bucket and the second sieve bucket screen the materials according to the data obtained by the measurement mechanism, and the hitting mechanism is used to hit the screened materials to adjust the shape of the materials; the pushing mechanism is used to push the materials into the detection mechanism Carry out hardness testing; through the shape measurement of flat materials, combined with multi-level hitting to correct the material shape, the shape that meets the strength measurement requirements can be achieved, and the continuous sorting, correction and strength measurement process of materials can be realized to meet the frequent measurement work during the excavation process The hardness requirements of the surface rock mass.

Description

technical field [0001] The present 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] During the construction of tunnels and roadways in coal mining, the geotechnical or coal seam characteristics of the excavation position of the working equipment directly affect the choice of construction plan. The hardness parameter of rock mass, as one of the important indicators of geotechnical properties, needs to be measured frequently during the excavation process. The rock mass hardness data at the excavation position 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 excavation through large-scale excavation equipment, it is often selected to sample the rock mass on the excavation face, and the hardness of the sample is measured and recorde...

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
