Description

Technical Field

[0001] The invention relates to the technical field of soil blasting, in particular to a gravel size scanning station. Background Art

[0002] Rock block size control is an important operation in mining and mineral engineering to control and minimize the cost of loading, transportation, crushing, classification and processing. In the prior art, the traditional method is to measure the size distribution of rock blocks through manual measurement and screening. With the continuous development of 3D laser scanning technology, 3D laser scanners use grating projection technology to obtain a 3D model of the crushed stone by scanning the crushed stone at multiple angles. The 3D laser scanner's online block size scanning and real-time automatic analysis system can perform real-time online analysis of the rock block size, which can form an important reference for blasting collapse or rock drilling design, and is conducive to controlling the block size of the generated rock blocks, so as to save the cost of multiple crushing caused by excessive block size caused by manpower and machinery.

[0003] A patent application with publication number CN114818019A discloses a rock block size identification method, the method steps are as follows: S1, establish a three-dimensional geometric analysis mathematical model of rock blocks composed of point cloud data; S2, extract the three-dimensional geometric dimensions of rock blocks in stages, and build a three-dimensional image and rock block grading database; S3, output the rock block size distribution curve. The invention obtains point cloud data of the blast pile and rock block surface by three-dimensional laser scanning, builds a three-dimensional image and rock block grading database, completes the rock block size identification by data comparison, improves the efficiency and accuracy of rock block size identification, and scans the blast pile by a three-dimensional laser scanning device. The three-dimensional laser scanning device is provided with a horizontal measurement component to ensure that the three-dimensional laser scanning head remains horizontal during the scanning process, and prevents the scanned image from being difficult to match due to the influence of the site on the scanning head during the segmented scanning process.

[0004] In the above scheme, an identification and detection system based on three-dimensional laser scanning technology is established to conduct block size analysis on gravel and stone blocks, which to a certain extent realizes the acquisition of block size characteristics of regional rock blocks. However, the above technical scheme still has shortcomings. Among them, the three-dimensional laser scanning head can move in the horizontal and vertical directions, but the scanning direction of the three-dimensional laser scanning head is fixed. When scanning the blast pile, the three-dimensional laser scanning head with a fixed direction is difficult to scan multiple surfaces of the gravel, and the gravel inside the blast pile is difficult to scan. After a single scan, the data information of the blast pile gravel is relatively small, and it is difficult to quickly generate more three-dimensional models of gravel, which is not conducive to the subsequent analysis of the blast volume.

[0005] To this end, the present invention provides a gravel size scanning station. Summary of the invention

[0024] How it works When the position of the 3D laser scanner 4 needs to be adjusted: The driving motor 1 21 drives the lead screw 1 25 to rotate, so that the slider 23 moves in the groove 22, and then drives the rotating mechanism 3 and the three-dimensional laser scanner 4 below to move; When the angle of the 3D laser scanner 4 needs to be adjusted: The electric telescopic rod 34 is driven to drive the connecting block 35 to move in the slide rail 33, thereby driving the connecting rod 38 to move. The movement of the connecting rod 38 can cause the rotating rod 37 to rotate, thereby adjusting the angle of the three-dimensional laser scanner 4, and the rotating plate 32 and the three-dimensional laser scanner 4 below can be driven by the second driving motor 31 to rotate. When the rotation angle of the rotating plate 32 is adjusted, it will not rotate in the same direction, but will rotate in the opposite direction after rotating 180 degrees, so as to facilitate scanning of multiple surfaces of the crushed stone, obtain more comprehensive data information of the explosive piled crushed stone, and generate a three-dimensional model of the crushed stone; When the cabin 54 needs to be vibrated so that the gravel at the bottom can be scanned: The driving motor 3 71 rotates the driving shaft 72 driven by the motor 3 71, so that the rotating block 73 rotates. Since the rotating block 73 is eccentrically arranged with the driving shaft 72, the rotating block 73 can collide with the top compartment 54 when rotating, thereby causing the compartment 54 to vibrate. The rotation of the drive shaft 72 will drive the active bevel gear 81 and the driven bevel gear 82 to rotate, and then the driven shaft 83 and the screw 2 84 can rotate. Since the screw 2 84 is a reciprocating screw, the lifting block 85 on the screw 2 84 can be lifted and lowered reciprocatingly, that is, the push plate 87 can squeeze the airbag 88 reciprocatingly, and the gas in the airbag 88 is squeezed into the water tank 89. The water in the water tank 89 will flow to the water supply pipe 811 and the installation pipe 813 under the action of air pressure, and finally be sprayed out from the nozzle 814. After the airbag 88 is squeezed, a rebound restoring force is generated to restore the original shape. When the push plate 87 is lifted and lowered reciprocatingly, the airbag 88 is repeatedly squeezed and rebounded to ensure water spraying. The water is sprayed into the compartment 54, which can reduce dust inside the compartment 54, and can effectively reduce the impact of dust on the scanning of the three-dimensional scanner, ensure the accuracy of the scanning, and facilitate the acquisition of data information of the blast pile gravel.
