Description

Technical Field

[0001] This utility model relates to the technical field of measuring and classifying devices, and in particular to a device for measuring and classifying the size of blasted blocks in engineering. Background Technology

[0002] In engineering blasting processes such as mining, tunnel excavation, and site leveling, the post-blast block size distribution directly affects subsequent transportation, crushing, and mineral processing efficiency and energy consumption: excessively large blocks require secondary crushing, increasing costs; excessively small blocks result in increased dust and pollution. Therefore, rapid and accurate measurement and classification of blast block size is of great significance for engineering practice.

[0003] Existing measurement methods have obvious limitations: manual measurement relies on experience, is inefficient, highly subjective, and lacks objectivity; while image acquisition systems can accurately obtain block size distribution, they only provide statistical results and cannot solve the data deviation problem caused by the upper part of the image being covered. The stones still need to be sorted manually or with additional equipment, which increases the number of work steps.

[0004] While some current market devices combine detection and conveying functions, they mostly remain at the "measurement-display" level, failing to achieve real-time stone grading and automatic collection. The problems of low efficiency and high labor intensity remain unresolved. This disconnect between measurement and classification severely limits the application of this technology in mining and engineering construction.

[0005] In view of this, the inventors have designed a device for measuring and classifying the size of blasted blocks in engineering, which leads to this invention. Utility Model Content

[0006] The purpose of this application is to provide a device for measuring and classifying the size of blasted rocks in engineering, which at least solves the problem that blasted rocks can only be measured on site but cannot be automatically classified.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides an engineering blasting block size measurement and classification device, characterized in that it includes: a support base; a conveying mechanism for carrying and conveying blasted rocks; an image acquisition module disposed above the conveying mechanism for acquiring images of the blasted rocks; an image processing unit electrically connected to the image acquisition module for processing the images and obtaining block size information of the blasted rocks; a vibrating screening device disposed at the discharge end of the conveying mechanism for screening according to the particle size of the blasted rocks; and a material collection structure connected to the screen outlet of the vibrating screening device for collecting rocks of different particle sizes after screening.

[0008] In a further embodiment, the image acquisition module includes an industrial camera and supplementary lights, with the supplementary lights positioned on both sides of the industrial camera to improve the clarity of the acquired images.

[0009] In a further embodiment, the vibrating screening device includes a multi-stage screen frame, wherein the multi-stage screen frame is provided with screens of different aperture sizes from top to bottom, for classifying and screening blasted rocks.

[0010] In a further embodiment, a particle guide channel is provided below each of the multi-stage sieve frames, and the ends of the particle guide channels are connected to the corresponding material distribution and collection structures.

[0011] In a further embodiment, the conveying mechanism is a conveyor belt structure, with one end of the conveyor belt being the feed end and the other end being the discharge end that connects to the vibrating screening device.

[0012] In a further embodiment, the discharge end of the conveyor belt is equipped with a buffer plate, which is located above the feed inlet of the vibrating screening device to reduce the impact force of the blasted rocks and prevent damage to the screen.

[0013] In a further embodiment, a control panel and a power supply unit are also included. The control panel is located on the side wall of the support base, and the power supply unit is a battery pack or an external power source.

[0014] In a further embodiment, the image processing unit has a built-in data storage module for storing image data of the blasted rocks and the corresponding block size analysis results.

[0015] In a further embodiment, the material collection structure includes multiple independent collection boxes, which are detachably installed below the support base.

[0016] Compared with the prior art, the present invention has the following advantages: By installing an image acquisition module above the conveying mechanism and combining it with an image processing unit, the size of blasted rocks can be measured in real time. A vibrating screening device and a material collection structure are installed at the discharge end of the conveying mechanism, realizing automatic screening and classification of rocks. This avoids the shortcomings of traditional devices that can only measure and require manual or additional equipment for further grading. At the same time, the multi-stage screen frame combined with the guide channel structure design improves the classification accuracy. The buffer plate effectively reduces the impact of large rocks on the screen and extends its service life. Furthermore, the application of the control panel and power supply unit improves the portability and adaptability of the device. Overall, it realizes integrated, automated and efficient operation of blasted rock size measurement and classification.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] like Figure 1 As shown in the figure, this utility model embodiment provides an engineering blasting block size measurement and classification device. Its overall structure includes a support base 1, a conveying mechanism 2, an image acquisition module 3, an image processing unit 4, a vibrating screening device 5, and a material collection structure 6. The device conveys the blasted stones to the measurement and classification unit via the conveying mechanism 2. Based on image processing and combined with vibrating screening, it achieves automatic grading and collection of the stones, thereby improving the efficiency of blasting block size detection and classification.

[0022] The support base 1 serves as the fundamental load-bearing component of the device. It employs a metal frame structure and features adjustable anchor bolts at the bottom to adapt to uneven ground conditions and ensure stability during vibration. The conveying mechanism 2 is fixed above the support base 1. In this embodiment, the conveying mechanism 2 is a conveyor belt structure. The feed end is connected to the blasting operation area, and stones fall into the conveyor belt through the feed end and move along the conveying direction to the discharge end. To prevent large stones from impacting the subsequent screen, a buffer plate 8 is installed above the discharge end of the conveyor belt. This buffer plate 8 can be made of wear-resistant steel plate or rubber lining, which can both reduce the impact force of the stones and effectively extend the service life of the screen.

[0023] like Figure 1 As shown, the image acquisition module 3 is installed above the middle section of the conveyor belt and fixed to the crossbeam support. It mainly includes an industrial camera 31 and supplementary lights 32. The industrial camera 31 faces the conveyor belt and acquires images of the stones in real time during the conveying process. The supplementary lights 32 are arranged on both sides of the industrial camera 31 to provide a stable light source under conditions of insufficient light or uneven lighting, ensuring the clarity and contrast of the acquired images. The image acquisition module 3 is electrically connected to the image processing unit 4, which is located inside the support base 1. The image processing unit 4 has a built-in processor and data storage module, which can perform real-time analysis on the acquired images, calculate the size information of the stones, and store the analysis results for subsequent statistical or quality assessment.

[0024] A vibrating screen 5 is installed at the discharge end of the conveyor belt. Driven by a motor and coupling, the vibrating screen 5 generates high-frequency vibration to screen the stones. In this embodiment, the vibrating screen 5 adopts a multi-stage screen frame structure, with screens of different aperture sizes arranged sequentially from top to bottom to divide the stones into several particle size ranges. Each stage of the screen frame has a particle guide channel 7 below it, with an inclined structure to guide the screened stones to the material distribution and collection structure 6. The material distribution and collection structure 6 consists of multiple independent collection boxes, all of which can be detachably installed below the support base 1. Stones of different particle sizes enter their respective collection boxes for convenient centralized transfer or subsequent processing.

[0025] like Figure 1 As shown, for ease of use on site, a control panel 91 and a power supply unit 92 are installed on the side wall of the device. The control panel includes a start button, running status indicator lights, and a power display module. The device is powered by a battery pack or an external power supply to meet the needs of use in complex construction environments. The battery pack has overload protection to ensure safe operation of the device during vibration and image processing. The power supply unit 92 is either a battery pack or an external power supply.

[0026] In this embodiment, during operation, as the stones are conveyed by the conveyor belt, they are first captured in real time by the image acquisition module 3. The image processing unit 4 analyzes and outputs the block size information in real time, realizing automatic measurement of the blasted block size. When the stones enter the vibrating screening device 5, they are graded by passing through screens of different aperture sizes in sequence, and finally enter the corresponding collection box through the guide channel to complete the classification and storage. This process realizes the integrated operation of "measurement-grading-collection" of blasted stones, reducing manual intervention.

[0027] Compared with existing technologies, this utility model integrates an automatic screening and collection unit on the basis of image measurement, avoiding the problem that traditional devices can only measure but not classify. The classification accuracy is improved by setting up multi-level screen frames and guide channels; the buffer plate 8 effectively reduces the risk of screen damage; the detachable collection box facilitates flexible transportation; and the data storage module ensures the traceability of measurement results. Overall, this device has a reasonable structure and is easy to use, which can significantly improve the operational efficiency and intelligence level of blasting construction sites.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
