Description

Technical Field

[0001] This utility model relates to the field of belt conveyor protection technology, specifically a device for preventing material spillage on belt conveyors. Background Technology

[0002] In industrial production and conveying, belt conveyors, as core equipment for the continuous transport of bulk materials, are widely used in mining, metallurgy, chemical, and building materials industries. Belt conveyors are widely used in loading equipment as material conveying devices. They transport materials along their conveyor belts, but when the material exceeds the belt's carrying capacity, spillage occurs. Significant spillage can lead to transport quality accidents and material waste.

[0003] Traditional measures to prevent material spillage often involve installing baffles, skirts, or manual inspection and cleaning. However, these methods have significant limitations. The fixed structures of baffles and skirts are difficult to adapt to the different spill patterns of materials. Sticky materials tend to stick together and accumulate, and after long-term use, the edges wear due to material friction, causing the leak-proof effect to gradually decrease over time. Manual inspection and cleaning not only require a large investment of manpower, but also need to be carried out while the conveyor belt is stopped, affecting continuous production efficiency. In addition, the accumulation of scattered materials around the equipment can easily cause safety hazards such as slipping and equipment jamming, making it difficult to meet the requirements of modern industrial production for efficient, stable, and energy-saving equipment operation.

[0004] Therefore, we propose a device for preventing material spillage on belt conveyors to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a device for preventing material spillage on belt conveyors, so as to solve the problem mentioned in the background art that it is difficult to effectively collect materials, causing materials to spill and accumulate around the equipment, resulting in safety hazards such as slipping and equipment jamming.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing material spillage on a belt conveyor, comprising a belt conveyor body, a crossbeam fixedly connected to the belt conveyor body, a mounting base fixedly connected to the crossbeam, a base fixedly connected to the top of the mounting base, a limiting baffle fixedly connected to the base, a support spring fixedly connected to the base, a receiving plate fixedly connected to the other end of the support spring, a support assembly mounted on the base, the support assembly comprising a front support block one and a rear support block two fixedly connected to the base, a front bracket hinged to one end of the front support block one, a rear bracket hinged to one end of the rear support block two, a rear support block one hinged to the other end of the front bracket, and a front support block two hinged to the other end of the rear bracket; The receiving tray is fixed with a counterweight mounting hook at one end. A scraping assembly is installed on the base. The scraping assembly includes a scraper that is slidably connected to the receiving tray. A receiving seat is installed on the bottom surface of the base. A rotating shaft is rotatably connected inside the receiving seat. A support foot is fixedly sleeved on the outer ring of the rotating shaft. A locking assembly is installed on the end of the rotating shaft.

[0007] Preferably, both the rear support block one and the front support block two are fixedly connected to the bottom surface of the receiving disk.

[0008] Preferably, there are two of each of the following: front support block one, front bracket, rear support block one, rear support block two, rear bracket, and front support block two, all symmetrically arranged about the receiving disk.

[0009] Preferably, a support frame is symmetrically fixed to the side wall of the base, a concave seat is fixed on the support frame, a motor is fixed to the side wall of the concave seat, a lead screw is fixedly connected to the output end of the motor, and the lead screw is rotatably connected to the concave seat.

[0010] Preferably, the outer ring of the lead screw is threaded with an L-shaped slide block, and a concave groove is formed in the concave seat. The L-shaped slide block and the concave seat are slidably connected through the concave groove.

[0011] Preferably, a scanner is fixed on the L-shaped slide, and a telescopic rod and an electric push column are fixed on the bottom surface of the L-shaped slide. The bottom surfaces of the telescopic rod and the electric push column are fixedly connected to the top surface of the scraper. The scraper is L-shaped, and the surface of the scraper that contacts the receiving plate is inclined.

[0012] Preferably, the locking assembly includes a threaded groove one formed on the outer ring of the rotating shaft, a through groove formed on the side wall of the receiving seat, a threaded groove two formed on the inner wall of the through groove, a collar threadedly installed on the outer ring of the rotating shaft through the threaded groove one, a retaining ring fixed on the side wall of the collar, and the retaining ring engaging with the through groove.

[0013] Preferably, the inner wall of the collar is provided with an external thread one that is threaded to the screw groove one, and the outer wall of the retaining ring is provided with an external thread two that is threaded to the screw groove two.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The receiving tray precisely catches material overflowing from the edge of the conveyor belt. When the accumulated weight reaches a threshold, it automatically flips back onto the conveyor belt, achieving closed-loop material recycling. This significantly reduces material loss caused by spillage and improves resource utilization efficiency. Utilizing the elastic deformation characteristics of the support springs, the kinetic energy of the material impact is converted into elastic potential energy, effectively buffering and reducing the load of the instantaneous impact on the receiving tray and the entire device. This prevents component damage caused by long-term impact, reduces equipment maintenance frequency and costs, and extends the device's service life. A stable four-bar support system is formed through the hinged rotation of the front support block and the front bracket, and the coordinated adjustment structure composed of the rear support block, ensuring the receiving tray withstands impacts and flipping during unloading. Maintaining structural stability throughout the process prevents operational interruptions or malfunctions due to postural imbalance, thus improving the reliability of the equipment. Through a counterweight adjustment mechanism, the weight of the counterweight can be flexibly adjusted according to the material conveying volume and the strength of the impact kinetic energy. This lowers the center of gravity to improve impact resistance during high conveying volumes and ensures responsiveness to minor impacts during low conveying volumes, allowing the equipment to adapt to different material characteristics and operating conditions, enhancing its versatility and practicality. It effectively intercepts spilled materials, preventing them from accumulating on the ground around the conveyor belt, reducing the workload of manual cleaning, lowering on-site cleaning costs, improving the cleanliness of the working environment, and reducing safety hazards caused by material accumulation.

[0015] 2. The scanner monitors the material accumulation in the receiving tray in real time, accurately captures the flipping threshold, and triggers linked operations to achieve automated start and stop of material collection and return. This avoids the lag and error of manual judgment, ensuring that the material is returned at the optimal time, improving recycling efficiency and timeliness. The electric push column drives the scraper to fit tightly against the inner wall of the receiving tray, and the motor drives the lead screw to achieve horizontal movement. During the material return stage, the accumulated material is scraped apart to prevent clumping and affecting the return effect. A secondary cleaning program is initiated for residual material, using the scraper's inclined surface design and full horizontal movement to thoroughly remove residue from the tray surface, avoiding problems such as device jamming or incomplete recycling caused by material adhesion and accumulation. The entire process from material collection, threshold monitoring, return operation to residue cleaning requires no manual intervention. The mechanical structure and intelligent control work together to complete all operational steps, significantly reducing the workload of manual inspection, operation, and cleaning, lowering labor costs, and avoiding potential safety hazards from manual operation.

[0016] 3. The double-threaded locking structure, formed by the connection of the collar and the first threaded groove of the rotating shaft and the engagement of the retaining ring and the second threaded groove of the receiving seat, can rigidly fix the angle of the support legs. This effectively prevents the support legs from loosening and displacing due to vibration and impact during the operation of the device, thus avoiding problems such as tilting and shaking. It also reduces safety hazards such as component collisions and functional failures caused by equipment displacement, providing a solid structural safety guarantee for the normal operation of the spill prevention device and reducing the risk of failure and the incidence of safety accidents during equipment operation.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figure 1 - Figure 3A device for preventing material spillage on a belt conveyor includes a belt conveyor body 1. The belt conveyor body 1 serves as the basic load-bearing and transport unit of the entire material conveying system, responsible for transferring materials from one location to another. A crossbeam 2 is fixedly connected to the belt conveyor body 1, and a mounting base 3 is fixedly fixed to the crossbeam 2. The mounting base 3 and the crossbeam 2 are connected by welding, bolting, or other methods to form a single unit, providing a mounting position for a base 4 and ensuring the stability of the base 4 during operation, preventing displacement or shaking. The base 4 is fixed to the top of the mounting base 3, and a limiting baffle 5 is fixed to the base 4. The limiting baffle 5 limits the swing angle of the front support 82, preventing the receiving tray 7 from failing to return to its original position after being emptied of material due to excessive swing angle. A support spring 6 is fixed to the base 4. The selection of the support spring 6 requires precise calculation and selection based on factors such as the weight of the material, the conveying speed, and the potential impact force. Cylindrical helical compression springs are typically used, as they have good elasticity and stability, enabling them to quickly return to their original shape while withstanding the impact force of the material, providing continuous and stable support for the receiving tray 7.

[0021] A receiving plate 7 is fixed to the other end of the supporting spring 6. The receiving plate 7 can completely collect any spilled material. A counterweight mounting hook 9 is fixed to the end of the receiving plate 7. The counterweight mounting hook 9 is used to install a counterweight block of appropriate weight according to actual working needs, so as to adjust the balance of the receiving plate 7 and its ability to withstand the impact force of the material. The counterweight block is usually made of cast iron or steel, and its weight can be selected and adjusted according to the actual situation.

[0022] A support assembly 8 is installed on the base 4. The support assembly 8 includes a front support block 1 81 and a rear support block 2 84 fixedly connected to the base 4. A front bracket 82 is hinged to one end of the front support block 1 81, and a rear bracket 85 is hinged to one end of the rear support block 2 84. A rear support block 1 83 is hinged to the other end of the front bracket 82, and a front support block 2 86 is hinged to the other end of the rear bracket 85. Both the rear support block 1 83 and the front support block 2 86 are fixedly connected to the bottom surface of the receiving disk 7. There are two of each of the following: front support block 1 81, front bracket 82, rear support block 1 83, rear support block 2 84, rear bracket 85, and front support block 2 86. The symmetrical structure can evenly bear the various forces on the receiving disk 7, ensuring the stability of the receiving disk 7 during operation.

[0023] In this embodiment: First, the main body of the device is aligned and installed with the pre-set crossbeam 2 of the belt conveyor body 1 via the mounting base 3 at the bottom, ensuring that the connecting holes of the mounting base 3 are precisely aligned with the reserved screw holes of the crossbeam 2. Then, bolts are passed through the connecting holes, and the bolts are tightened step by step in a symmetrical sequence using a wrench until the mounting base 3 and the crossbeam 2 are tightly fitted without any loose gaps, thus completing the rigid fixation of the device. After the fixation is completed, the device enters the standby state and can be put into normal use at any time, waiting for the belt conveyor to start to perform material spillage prevention operations.

[0024] When the conveyor belt 1 starts running, the material is conveyed forward by the cyclical movement of the conveyor belt. During this process, due to multiple factors such as the material's own fluidity, belt vibration, and conveying angle, some material is prone to overflow from the edge of the belt. This overflowing material will impact the receiving plate 7 with a certain kinetic energy. At this time, the receiving plate 7 absorbs the impact force and transmits the force to the support spring 6 at the bottom. Due to the excellent elastic deformation characteristics of the support spring 6, it will undergo compression deformation under the impact force, causing the receiving plate 7 to move downward with the spring contraction. This displacement process is actually a physical process in which the support spring 6 efficiently converts the kinetic energy of the material into elastic potential energy. Through the buffering and unloading effect of the spring, the impact load of the material on the receiving plate 7 and the entire device can be reduced, effectively avoiding device damage or secondary material splashing caused by excessive instantaneous impact force.

[0025] When the front end of the receiving tray 7 is impacted and displaced downwards by material, the hinge joint between the front support block 1 81 and the front bracket 82 will rotate adaptively. The front bracket 82 will adjust its tilt angle synchronously with the displacement of the receiving tray 7. At the same time, the connection structure composed of the rear support block 1 83 and the front support block 2 86 will also adjust its posture in coordination. A stable four-bar support system is formed by the symmetrically distributed support components 8 to ensure that the receiving tray 7 maintains structural stability during the stress process. As the material continues to accumulate in the receiving tray 7, when the cumulative weight reaches a preset threshold, the deformation force generated by the support spring 6 due to the excessive force will drive the receiving tray 7 to rotate around the hinge axis, pushing the collected material back onto the conveyor belt of the belt conveyor body 1. After unloading, the receiving tray 7 returns to its initial position under the combined action of its own gravity and the reset tension of the support spring 6, waiting for the next round of material collection.

[0026] To adapt to different working conditions, the device achieves dynamic balance through a counterweight adjustment mechanism. When the material conveying volume is large and the impact kinetic energy is strong, the weight of the counterweight can be increased to lower the center of gravity of the receiving pan 7 and improve its impact resistance stability. Conversely, when the conveying volume is small and the impact force is weak, the weight of the counterweight can be reduced to avoid reducing the response sensitivity to minor impacts due to the excessive weight of the receiving pan 7. Through counterweight adjustment, it can be ensured that the receiving pan 7 maintains the optimal balance under various working conditions and continuously and efficiently completes material receiving and processing operations.

[0027] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 - Figure 4 A scraper assembly 10 is installed on the base 4 to clean up residual material when the receiving tray 7 completes the material flipping and unloading, so as to avoid material accumulation affecting the cyclic operation of the device.

[0028] The scraping assembly 10 includes a scraper 109 slidably connected in the receiving tray 7. A support frame 101 is symmetrically fixed on the side wall of the base 4. A concave seat 102 is fixed on the support frame 101. A motor 103 is fixed on the side wall of the concave seat 102. A lead screw 104 is fixedly connected to the output end of the motor 103. The lead screw 104 is rotatably connected to the concave seat 102. An L-shaped slide 105 is threaded on the outer ring of the lead screw 104. A concave groove is opened in the concave seat 102 to ensure the sliding stability of the L-shaped slide 105. The L-shaped slide 105 and the concave seat 102 are slidably connected through the concave groove.

[0029] A scanner 106 is fixed on the L-shaped slide 105. The scanner 106 is used to detect the position and thickness of the residual material in the receiving tray 7 in real time, providing data support for the scraping action. A telescopic rod 107 and an electric push column 108 are fixed on the bottom surface of the L-shaped slide 105. The bottom surfaces of the telescopic rod 107 and the electric push column 108 are fixedly connected to the top surface of the scraper 109. The electric push column 108 is used to drive the scraper 109 to achieve vertical lifting and lowering, adapting to material residues of different thicknesses. The scraper 109 is L-shaped, and the contact surface between the scraper 109 and the receiving tray 7 is set at an angle to ensure close contact with the inner wall of the receiving tray 7 and improve scraping efficiency.

[0030] In this embodiment: During the material collection process, the scanner 106 monitors the amount of material accumulated in the receiving tray 7 in real time. When the material reaches the preset flipping threshold, it immediately sends a signal to the control system to trigger the linkage operation. The electric push column 108 extends and drives the scraper 109 to move down until it is tightly attached to the inner wall of the receiving tray 7. Then the motor 103 starts, and its output torque is transmitted to the lead screw 104 through the coupling. The lead screw 104 rotates and drives the threaded L-shaped slide 105 to move horizontally along the guide groove of the concave seat 102, so that the scraper 109 performs scraping operation synchronously with the flipping action of the receiving tray 7. This process can scrape the accumulated material and effectively prevent the material from clumping and affecting the return effect.

[0031] After the material return is completed, the electric push column 108 retracts, causing the scraper 109 to move upward and detach from the inner wall of the receiving tray 7. The support spring 6, after being relieved of force, drives the receiving tray 7 to flip and reset, returning to its initial position to continue waiting. If the scanner 106 detects material residue in the receiving tray 7, the system will restart the cleaning program. The electric push column 108 drives the scraper 109 downward to adhere to the tray surface, and the motor 103 drives the lead screw 104 to move the L-shaped slide 105 horizontally, allowing the scraper 109 to thoroughly clean along the length of the receiving tray 7. When residual material is pushed to the front end of the receiving tray 7, the electric push column 108 retracts due to the inclined design of the scraper 109, using the guiding force of the inclined surface to completely scrape away the residual material. After cleaning, the scraper 109 returns to its initial position under the coordinated control of the motor 103 and the electric push column 108, and the entire device returns to standby mode, awaiting the start of the next material collection cycle.

[0032] This fully automated material collection, return, and cleaning mechanism, through the organic combination of mechanical structure and intelligent control, achieves efficient prevention and control of material spillage from belt conveyors, and improves the stability and economy of the conveying system.

[0033] Example 3: This example is an improvement on Example 2. For details, please refer to [link / reference]. Figure 1 - Figure 2 and Figure 5 - Figure 6 The base 4 has a receiving seat 11 installed on its bottom surface. A rotating shaft 121 is rotatably connected inside the receiving seat 11. A support foot 12 is fixedly sleeved on the outer ring of the rotating shaft 121. A locking component 13 is installed on the end side of the rotating shaft 121. The locking component 13 includes a first threaded groove 131 opened on the outer ring of the rotating shaft 121. A through groove 132 is opened on the side wall of the receiving seat 11. A second threaded groove 133 is opened on the inner wall of the through groove 132. A collar 134 is threadedly installed on the outer ring of the rotating shaft 121 through the first threaded groove 131. A retaining ring 136 is fixed on the side wall of the collar 134. The retaining ring 136 is engaged with the through groove 132.

[0034] The inner wall of the collar 134 is provided with an external thread 135 that is threaded to the threaded groove 131, and the outer wall of the retaining ring 136 is provided with an external thread 137 that is threaded to the threaded groove 133. When the retaining ring 136 is inserted into the through groove 132, the threaded engagement can achieve rigid locking of the rotating shaft 121.

[0035] In this embodiment: After the device is installed in place, final fixing and debugging are completed through the adjustment mechanism of the support leg 12. During operation, firstly rotate the collar 134 to move it axially along the threaded groove 131 of the rotating shaft 121, causing the side retaining ring 136 to completely disengage from the through groove 132 of the receiving seat 11. At this time, the external thread 137 on the outer wall of the retaining ring 136 is completely separated from the threaded groove 133 on the inner wall of the through groove 132, and the rotating shaft 121 is released from the locking constraint and enters a free rotation state. The operator can then rotate the rotating shaft 121, and the support leg 12 fixed to the outer ring of the rotating shaft 121 rotates synchronously with the shaft until the support leg 12 unfolds to a support angle perpendicular to the bottom surface of the base 4, ensuring that the bottom end of the support leg 12 makes stable contact with the ground to form effective support.

[0036] After the support leg 12 is adjusted to the correct angle, the collar 134 is rotated in the opposite direction to move it along the threaded groove 131 towards the side wall of the receiving seat 11, causing the retaining ring 136 to gradually embed into the through groove 132. When the retaining ring 136 is fully inserted into the through groove 132, the collar 134 is rotated further to make the external thread 137 on the outer wall of the retaining ring 136 precisely engage with the threaded groove 133 on the inner wall of the through groove 132. The locking force between the threads achieves rigid fixation between the collar 134 and the receiving seat 11. At this time, the collar 134 forms a rigid connection with the rotating shaft 121 through the threaded groove 131, and the retaining ring 136 forms a stable lock with the receiving seat 11 through the threaded groove 133. The rotating shaft 121 is completely limited and cannot rotate, and the angle of the support leg 12 is precisely fixed.

[0037] This double-threaded locking structure ensures that the support leg 12 remains stable during device operation, effectively preventing loosening and displacement, providing a solid foundation for the entire spill prevention device, and improving the stability and safety of equipment operation.
