Description

Technical Field

[0001] This invention relates to the field of conveyor belts, and more specifically, to an automatic material discharge device for conveyor belts. Background Technology

[0002] In industries such as metallurgy, mining, power, and building materials, belt conveyors are core equipment in continuous material conveying systems, widely used in the transfer of bulk materials such as coal, ore, steel slag, and sludge. Typically, a single main conveyor belt supplies material to multiple downstream processes or silos in segments. When switching discharge positions, diversion baffles guide the material flow to a designated outlet. However, in actual operation, due to material characteristics (such as high humidity, strong viscosity, fine particles, or susceptibility to electrostatic adsorption) and inadequate equipment sealing, some material leaks through the gaps between the conveyor belt and the baffles, accumulating in the area directly below the conveyor. Especially when conveying highly viscous materials such as wet steel slag, sludge, and coal slime, the leaked material easily adheres to the diversion baffles, idlers, and the inner walls of the frame. Over time, this accumulation and hardening reduces the effective flow area of ​​the discharge channel, ultimately leading to poor discharge or even complete blockage.

[0003] Currently, the main solution to this type of material accumulation problem relies on regular manual cleaning. Operators must use shovels, crowbars, and other tools to dig into the narrow space under the conveyor belt, whether the conveyor belt is running or stopped. This method is not only labor-intensive and inefficient, but also poses serious safety hazards: if tools are caught in the running belt, it could easily trigger a chain reaction of mechanical accidents, causing equipment damage or personal injury. Therefore, there is an urgent need for a simple, safe, reliable, and automatically preventative material discharge device that can effectively prevent material adhesion and accumulation under the conveyor belt, guide leaked material to an easily cleanable location, completely eliminate the need for manual entry into hazardous areas, and improve production safety and maintenance efficiency. Summary of the Invention

[0004] This invention provides an automatic material discharge device for conveyor belts, which can automatically clean the diversion baffles, reduce labor intensity, and improve cleaning efficiency.

[0005] The embodiments of the present invention can be implemented as follows: An embodiment of the present invention provides an automatic material discharge device for a conveyor belt conveyor, comprising: Conveyor belt; Diverting baffles are provided along the running direction of the conveyor belt and are used to guide materials falling from the conveyor belt to both sides of the conveyor belt. A vibrator connected to the diversion baffle, the vibrator being used to strike the diversion baffle.

[0006] Optionally, the diversion baffle includes a first baffle and a second baffle, which are respectively disposed on both sides of the conveyor belt. The first baffle and the second baffle are respectively used to guide the material falling from the conveyor belt to both sides of the conveyor belt.

[0007] Optionally, the first baffle includes two stainless steel plates, which are joined together to form a triangular structure.

[0008] Optionally, the bottom angle of the first baffle is 55°-65°.

[0009] Optionally, the first baffle and the second baffle have the same shape.

[0010] Optionally, both the first baffle and the second baffle have an anti-sticking layer on their surfaces.

[0011] Optionally, the number of the vibrators is at least one.

[0012] Optionally, the automatic discharge device for the conveyor belt further includes a support plate, and the diverting baffle is fixed on both sides of the conveyor belt by the support plate.

[0013] Optionally, the automatic discharge device for the conveyor belt further includes a pressure sensor and a control module. The pressure sensor is connected to the control module, and the control module is connected to the vibrator. The pressure sensor is used to detect the material accumulation state on the diversion baffle, and the control module controls the start and stop of the vibrator based on the detection signal from the pressure sensor.

[0014] Optionally, the automatic discharge device for the conveyor belt further includes a vibration sensor, which is connected to the control module. The vibration sensor is used to detect the vibration response information of the diversion baffle, and the control module adjusts the working time and frequency of the vibrator based on the vibration response information.

[0015] The beneficial effects of the automatic material discharge device for conveyor belts according to embodiments of the present invention include, for example: This automatic material discharge device for a conveyor belt includes a conveyor belt, a diversion baffle, and a vibrator. The diversion baffle is positioned along the running direction of the conveyor belt and guides material falling from the conveyor belt to both sides. The vibrator is connected to the diversion baffle and strikes it. In operation, the diversion baffle, extending along the running direction below the conveyor belt, promptly catches material falling from the belt and guides it naturally to the sides of the belt using its inclined surface. This prevents material from accumulating in the narrow space directly below the belt, fundamentally changing the traditional passive situation of "material leakage leading to accumulation" and significantly improving the smoothness and stability of the discharge channel. The vibrator, connected to the diversion baffle, can automatically activate and strike the baffle under set conditions, generating vibration and impact force. This disrupts the adhesion between wet, sticky materials or electrostatically adsorbed materials and metal surfaces, allowing initially adhered material to fall off promptly and preventing its accumulation and blockage. This design enables proactive prevention and dynamic removal of material buildup hazards, significantly reducing reliance on regular manual cleaning. Attached Figure Description

[0024] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0025] In industries such as metallurgy, mining, power, and building materials, belt conveyors are core equipment in continuous material conveying systems, widely used in the transfer of bulk materials such as coal, ore, steel slag, and sludge. Typically, a single main conveyor belt supplies material to multiple downstream processes or silos in segments. When switching discharge positions, diversion baffles guide the material flow to a designated outlet. However, in actual operation, due to material characteristics (such as high humidity, strong viscosity, fine particles, or susceptibility to electrostatic adsorption) and inadequate equipment sealing, some material leaks through the gaps between the conveyor belt and the baffles, accumulating in the area directly below the conveyor. Especially when conveying highly viscous materials such as wet steel slag, sludge, and coal slime, the leaked material easily adheres to the diversion baffles, idlers, and the inner walls of the frame. Over time, this accumulation and hardening reduces the effective flow area of ​​the discharge channel, ultimately leading to poor discharge or even complete blockage.

[0026] Currently, the main method for addressing this type of material accumulation problem relies on regular manual cleaning. Operators must use shovels, crowbars, and other tools to dig into the confined space beneath the conveyor belt, whether the conveyor belt is running or stopped. This method is not only labor-intensive and inefficient, but also poses serious safety hazards: if tools are caught in the running conveyor belt, it can easily trigger a chain reaction of mechanical accidents, causing equipment damage or personal injury. Numerous safety incidents, both domestically and internationally, have been reported stemming from personnel or tools being caught in the running conveyor belt system during cleaning, exposing the inherent flaws of traditional material cleaning methods.

[0027] Therefore, there is an urgent need for a simple, safe, and reliable material discharge device that can automatically prevent blockages and effectively prevent material from adhering to and accumulating under the conveyor belt. This device can guide leaked material to an easy-to-clean location, completely eliminate the need for manual entry into hazardous areas, and improve production safety and maintenance efficiency.

[0028] Please refer to Figures 1-2 This embodiment provides an automatic discharge device 100 for conveyor belts, which can effectively improve the technical problems mentioned above, automatically clean the diversion baffle 20, reduce labor intensity, and improve cleaning efficiency.

[0029] The automatic discharge device 100 for the conveyor belt includes a conveyor belt 10, a diverting baffle 20, and a vibrator 30. The diverting baffle 20 is arranged along the running direction of the conveyor belt 10 and is used to guide the material falling from the conveyor belt 10 to both sides of the conveyor belt 10. The vibrator 30 is connected to the diverting baffle 20 and is used to strike the diverting baffle 20.

[0030] Specifically, in existing technologies, manual cleaning of the diversion baffle 20 is commonly used. This method is not only labor-intensive and inefficient, but also poses serious safety hazards: if tools are caught in the running belt, it could easily trigger a chain reaction of mechanical accidents, causing equipment damage or personal injury. To solve this technical problem, the automatic discharge device 100 for conveyor belts provided in this embodiment, by setting a diversion baffle 20 extending along the running direction below the conveyor belt 10, can promptly catch materials leaking from the conveyor belt 10 and use its inclined surface to naturally guide the materials to slide down to both sides of the conveyor belt 10, avoiding the accumulation of materials in the narrow space directly below the belt. This fundamentally changes the traditional passive situation of "leaking material equals accumulation," significantly improving the smoothness and stability of the discharge channel. The vibrator 30 is connected to the diversion baffle 20 and can automatically start under set conditions to strike the diversion baffle 20, generating vibration and impact force to break the adhesion between wet, sticky materials or electrostatically adsorbed materials and the metal surface, allowing the initially adhered materials to fall off in time, preventing them from accumulating and forming hard lumps and blockages. This design enables proactive prevention and dynamic removal of material buildup hazards, significantly reducing reliance on regular manual cleaning.

[0031] In this embodiment, the diversion baffle 20 includes a first baffle 21 and a second baffle 22, which are respectively disposed on both sides of the conveyor belt 10. The first baffle 21 and the second baffle 22 are used to guide the material falling from the conveyor belt 10 to both sides of the conveyor belt 10. By designing the diversion baffle 20 to include the first baffle 21 and the second baffle 22, and respectively disposed on both sides of the conveyor belt 10, the material falling from the conveyor belt 10 can be effectively guided to slide and accumulate on both sides of the conveyor belt, rather than being concentrated in the narrow space directly under the belt. This arrangement changes the traditional problem of material accumulation under the belt being difficult to clean, allowing cleaning operations to be carried out in a safe area outside the conveyor belt 10 without requiring workers to put tools or their bodies under the running belt, significantly improving operational safety. At the same time, the double-sided diversion structure facilitates the natural dispersion of material, avoids excessively rapid local accumulation, extends the cleaning cycle, and improves discharge efficiency.

[0032] Specifically, the first baffle 21 comprises two stainless steel plates, which are joined together to form a triangular structure. This triangular structure, formed by two stainless steel plates, offers advantages such as easy processing, low cost, and strong corrosion resistance. Stainless steel possesses excellent anti-adhesion and wear resistance, making it particularly suitable for working environments with humid, highly viscous, or corrosive materials (such as wet steel slag and sludge), effectively reducing material adhesion to the baffle surface. The modular structure facilitates on-site installation and subsequent replacement and maintenance, eliminating the need for overall disassembly and improving the maintainability of the device. The triangular cross-section structure enhances the overall rigidity of the baffle, preventing deformation due to long-term stress or vibration and ensuring long-term stable operation.

[0033] In this embodiment, the base angle of the first baffle 21 is 55°-65°. This angle range ensures that the material slides smoothly down the slope under gravity, while avoiding insufficient flow cross-section and easy blockage due to an excessively small angle, or excessive height space occupation and installation restrictions due to an excessively large angle. Within this range, the material sliding resistance is minimal and the self-cleaning ability is strongest. Specifically, the base angle of the first baffle 21 is 60°, that is, the first baffle 21 is an isosceles triangle. In other embodiments, the base angle of the first baffle 21 can be 55°, 62°, or 65°, and no specific limitation is made here.

[0034] Understandably, the first baffle 21 and the second baffle 22 have the same shape. The identical shape of the first baffle 21 and the second baffle 22 achieves standardized and symmetrical structural design. On the one hand, this facilitates mass production and reduces processing costs; on the other hand, they are interchangeable during installation, simplifying the construction process and reducing the types of spare parts.

[0035] In addition, both the first baffle 21 and the second baffle 22 have an anti-sticking layer on their surfaces. By setting the anti-sticking layer on the surfaces of the first baffle 21 and the second baffle 22, the adhesion and accumulation of materials on the baffle surfaces are effectively reduced, which is especially suitable for materials with sticky or easily agglomerated characteristics (such as wet coal, slag, chemical powder, etc.). This technology significantly improves the smoothness of material discharge, reduces the frequency of manual cleaning and equipment maintenance costs, and avoids blockage or uneven loading problems caused by material accumulation.

[0036] In this embodiment, there is at least one rapper 30. The distribution of rapping points can be flexibly configured according to the length of the diversion baffle 20, the material flow rate, and the risk of blockage. Multiple rappers 30 working together can achieve segmented, alternating, or synchronous tapping of different areas of the baffle, enhancing the unblocking effect.

[0037] Specifically, in this embodiment, there are two vibrators 30, one on the first baffle 21 and one on the second baffle 22. The vibrator 30 has a power of 0.9KW and is activated for 5-10 seconds every 30 minutes, generating a high-frequency impact force to effectively break the adhesion between the material and the diversion baffle 20, thereby shaking the material off.

[0038] Furthermore, the automatic discharge device 100 for the conveyor belt also includes a support plate, and the diverting baffle 20 is fixed to both sides of the conveyor belt 10 by the support plate. By adding the support plate to firmly fix the diverting baffle 20 to both sides of the conveyor belt 10, the mechanical stability and load-bearing capacity of the overall structure are enhanced, and the baffle is prevented from loosening, deforming or even falling off due to material impact or vibration.

[0039] In this embodiment, the support plate is an iron plate, which is embedded on both sides of the conveyor belt 10 to fix the first baffle 21 and the second baffle 22.

[0040] It should also be noted that the automatic discharge device 100 for the conveyor belt includes a vibration sensor, a pressure sensor, and a control module. The pressure sensor is connected to the control module, and the control module is connected to the vibrator 30. The pressure sensor is used to detect the material accumulation state on the diversion baffle 20, and the control module controls the start and stop of the vibrator 30 based on the detection signal from the pressure sensor. The vibration sensor is connected to the control module and is used to detect the vibration response information of the diversion baffle 20. The control module adjusts the working time and frequency of the vibrator 30 based on the vibration response information.

[0041] Specifically, when the pressure sensor detects that the material accumulation on the diversion baffle 20 exceeds the set threshold, the control module automatically starts the vibrator 30 to clear the blockage; when the pressure drops back to a safe range, the vibrator automatically stops. This closed-loop control mechanism avoids the energy waste and mechanical wear caused by traditional timed vibrators, improves the system's intelligence level and energy efficiency ratio, and ensures timely material discharge and continuous conveying.

[0042] The automatic material discharge device 100 for a conveyor belt conveyor provided in this embodiment has at least the following advantages: Since the material is guided to the areas on both sides of the conveyor belt 10 for centralized discharge, operators no longer need to extend cleaning tools into the narrow space under the running belt to dig, which completely avoids the risk of tools or people being caught in the running belt, effectively prevents mechanical injury accidents, and greatly improves the inherent safety level of on-site maintenance operations.

[0043] This device only requires the addition of a diverter baffle 20 and a vibrator 30 to the existing conveyor belt 10. It features a compact structure, convenient installation, and does not alter the main structure of the original equipment. All materials used (such as stainless steel plates and conventional vibrators 30) are general-purpose industrial components, resulting in low procurement and maintenance costs. It is particularly suitable for working environments with high humidity and strong viscosity materials in industries such as metallurgy, mining, power, and environmental protection, demonstrating excellent engineering applicability and promising industrialization prospects.

[0044] The 30 vibrator adopts an intermittent working mode (which can be expanded to intelligent control in the future), resulting in low energy consumption. At the same time, by reducing material accumulation, it reduces corrosion and wear on components such as rollers and supports, which helps to extend the service life of the entire machine and reduce maintenance costs.

[0045] In summary, this invention provides an automatic discharge device 100 for a conveyor belt conveyor. The device includes a conveyor belt 10, a diverting baffle 20, and a vibrator 30. The diverting baffle 20 is positioned along the running direction of the conveyor belt 10 and guides material falling from the conveyor belt 10 to both sides of the conveyor belt 10. The vibrator 30 is connected to the diverting baffle 20 and is used to strike the diverting baffle 20. In use, by providing a diverting baffle 20 extending along the running direction below the conveyor belt 10, it can promptly catch material falling from the conveyor belt 10 and naturally guide the material to both sides of the conveyor belt 10 using its inclined surface. This prevents material from accumulating in the narrow space directly below the belt, fundamentally changing the traditional passive situation of "material leakage leading to accumulation," and significantly improving the smoothness and stability of the discharge channel. The vibrator 30 is connected to the diversion baffle 20 and can automatically start under set conditions to strike the diversion baffle 20, generating vibration and impact force. This disrupts the adhesion between wet, sticky materials or electrostatically adsorbed materials and the metal surface, allowing initially adhered materials to fall off in time and preventing them from accumulating and forming hard lumps that cause blockages. This design achieves proactive prevention and dynamic removal of material accumulation hazards, significantly reducing the reliance on regular manual cleaning.

[0046] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
