Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a cold aggregate conveyor belt. Background Technology

[0002] In the process of conveying aggregates, the conveyor belt system plays a crucial role. A traditional cold aggregate conveyor belt typically consists of basic components such as side support plates arranged parallel on both sides, a drive motor, a drive roller, a driven roller, a driven chain, and belt plates. Its main working principle is that the drive motor rotates the drive roller, and with the transmission of the driven chain, the belt plates circulate, thereby realizing the conveying of cold aggregates from one location to another.

[0003] However, with the continuous development and increasing demands of cold aggregate conveying operations, traditional conveyor belts have revealed numerous problems. During prolonged operation, cold aggregate tends to adhere to the belt surface. On the one hand, this adhered aggregate gradually accumulates, reducing the effective conveying area of ​​the belt and consequently affecting conveying efficiency. For example, in some large-scale construction aggregate processing production lines, reduced conveying efficiency may prevent the supply of aggregates to subsequent production stages, causing delays in the entire production process.

[0004] On the other hand, adhering aggregate may detach during conveyor belt movement due to friction and collision with other components, falling into other parts of the equipment and causing malfunctions. For example, if it falls into critical components such as the drive motor or driven chain, it may cause problems such as motor jamming, accelerated chain wear, or even breakage, increasing equipment maintenance costs and downtime. Moreover, if the adhering aggregate is carried into subsequent processing or use stages, it will also affect product quality. For instance, in asphalt concrete production, impurities mixed into cold aggregate may cause unstable performance of the asphalt concrete, reducing the construction quality of roads and other infrastructure.

[0005] To address these issues, some conveyor belt systems are currently employing simple cleaning methods, such as fixing brushes under the belt plate. However, these fixed brushes have significant drawbacks: the distance between them and the belt plate cannot be adjusted, and the cleaning effectiveness decreases considerably after the brushes wear down. Furthermore, when there is a thick buildup of aggregate or large particles adhering to the belt plate, the fixed brushes struggle to remove them effectively. Additionally, when cleaning is not required, the fixed brushes remain in contact with the belt plate, increasing the belt's running resistance and wasting energy.

[0006] Therefore, there is an urgent need for a cleaning mechanism that can effectively clean the surface of cold aggregate conveyor belts and has flexible adjustment functions, in order to overcome the defects in the existing technology and improve the reliability, stability and operating efficiency of cold aggregate conveyor belts. Utility Model Content

[0007] In view of the shortcomings of the prior art, the present invention provides a cold aggregate conveyor belt.

[0008] The technical solution adopted by this utility model is: a cold aggregate conveyor belt, including a support side plate arranged in parallel on both sides, a drive motor, a drive roller, a driven roller, a driven chain, and a belt plate. The drive roller and the driven roller are rotatably connected to both ends of the support side plate. The drive motor is driven and connected to the drive roller. The driven chain is connected to the drive roller and the driven roller. The belt plate is laid flat at equal intervals along the length of the driven chain. It also includes a lifting and cleaning mechanism.

[0009] The lifting and cleaning mechanism includes a mounting beam fixed to the side plate of the support, an arched frame fixed to the mounting beam, a lifting device fixed to the arched frame, a brush plate connected to the output end of the lifting device, and cleaning bristles evenly distributed on the brush plate.

[0010] Furthermore, the belt plate on the moving chain is provided with several partition plates at intervals.

[0011] Furthermore, the strip plate includes, from bottom to top, a metal base plate, a tear-resistant layer, a load-bearing layer, a buffer layer, and a wear-resistant layer.

[0012] Furthermore, the tear-resistant layer is a polyester fiber mesh, the load-bearing layer is a polyester canvas, the cushioning layer is a polyurethane foam layer, and the abrasion-resistant layer is a natural rubber-styrene-butadiene rubber layer.

[0013] Furthermore, the side plates of the support are also provided with adjustment mechanisms for adjusting the position of the driven roller.

[0014] Furthermore, the adjustment mechanism includes a bearing seat that is slidably fitted with a guide step on the side plate of the support and a long screw connected to the bearing seat. The long screw passes through a guide plate on one side of the support side plate and is fixed by a nut. The driven roller is rotatably connected to the bearing seat at both ends.

[0015] The beneficial effects of this utility model are:

[0016] 1. High-efficiency cleaning performance: The lifting and cleaning mechanism of this invention significantly improves the cleaning effect on the surface of the cold aggregate conveyor belt. The lifting device allows for precise control of the distance between the brush plate and the belt plate, enabling it to adapt to cold aggregates of varying thicknesses and adhesion levels. When faced with large accumulations or stubbornly adhered aggregates, the brush plate can be lowered to a suitable position, ensuring full contact between the cleaning bristles and the belt plate, effectively removing various impurities, maintaining the cleanliness of the belt plate surface, and thus consistently maintaining high conveying efficiency. This avoids problems such as reduced conveying area and decreased efficiency due to aggregate residue.

[0017] 2. Equipment Protection and Extended Service Life: Timely and thorough cleaning effectively prevents cold aggregate residue and detachment from the conveyor belt, avoiding damage to critical transmission components such as the drive motor and driven chain caused by detached aggregate. For example, it reduces the risk of motor overload, overheating, or even burnout caused by aggregate getting stuck in the motor, and lowers the risk of chain breakage due to foreign object wear. This significantly extends the service life of the entire conveyor belt system, reduces equipment maintenance frequency and costs, and ensures the continuity and stability of production operations.

[0018] 3. Energy Saving and Consumption Reduction: Because the lifting cleaning mechanism only brings the brush plate into close contact with the belt when cleaning is required, it can raise the brush plate to a position where it does not contact the belt plate during normal transport, significantly reducing the additional resistance of the belt plate during operation. Compared with the traditional fixed brush design, this effectively reduces the energy consumption of the drive motor, achieving the goal of energy saving and consumption reduction. This aligns with modern industry's pursuit of energy efficiency, and long-term operation can save significant electricity costs, improving the economic benefits of enterprises.

[0019] 4. Improved Product Quality Stability: Effective cleaning of the cold aggregate conveyor belt plates ensures the purity of aggregates transported to subsequent processing stages, preventing adverse effects on final product quality due to impurities. For example, in the production of high-quality concrete or other aggregate-related products, stable aggregate quality results in more uniform and reliable product performance indicators, improving product quality stability and market competitiveness. This helps companies establish a positive brand image and expand market share.

[0020] 5. Convenient Operation and Strong Adaptability: The lifting and cleaning mechanism features a reasonable design and simple operation. Components such as the mounting beams and arched frames fixed to the side plates of the support frame provide a stable and reliable installation foundation for the lifting device, facilitating precise control of the brush plate's lifting. This structural design allows the cleaning mechanism to adapt to different specifications and models of cold aggregate conveyor belts, exhibiting strong versatility and adaptability. It can be widely applied in various aggregate conveying scenarios, providing enterprises with greater flexibility and convenience in equipment selection and upgrades.

[0021] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0028] 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.

[0029] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0030] This utility model provides a cold aggregate conveyor belt.

[0031] In this embodiment, refer to Figure 1-5 The cold aggregate conveyor belt includes a support side plate 1 parallel to both sides, a drive motor 2, a drive roller 3, a driven roller 4, a driven chain 5, and a belt plate 6. The drive roller and the driven roller are rotatably connected to both ends of the support side plate. The drive motor is driven by the drive roller. The driven chain is connected to the drive roller and the driven roller. The belt plate is laid flat at equal intervals along the length of the driven chain. The conveyor belt also includes a lifting and cleaning mechanism.

[0032] The lifting and cleaning mechanism includes a mounting beam 7 fixed on the side plate 1 of the support, an arched frame 8 fixed on the mounting beam 7, a lifting device 9 fixed on the arched frame 8, a brush plate 10 connected to the output end of the lifting device 9, and cleaning bristles 11 evenly distributed on the brush plate 10.

[0033] In the above technical solution, by adding a lifting and cleaning mechanism, flexible cleaning of the surface of the cold aggregate conveyor belt is achieved. When cleaning is required, the lifting device can be used to lower the brush plate, and the cleaning bristles can efficiently remove the cold aggregate and impurities adhering to the belt plate. This effectively solves the problems of inconvenient cleaning and easy material residue in traditional conveyor belts, significantly improving the cleanliness of the belt plate and conveying efficiency, reducing the risk of equipment failure due to material residue, and raising the brush plate when cleaning is not required to reduce the running resistance of the belt plate, achieve energy saving, extend the overall service life of the equipment, and improve the stability of system operation.

[0034] The lifting device is used to drive the brush plate to move up and down, and can be a cylinder, electric cylinder or other drive mechanism that can complete the up and down movement.

[0035] Specifically, the belt plate on the moving chain is provided with several partition plates 12 at intervals.

[0036] In this embodiment, several partition plates are spaced apart on the belt plate of the driven chain to effectively separate and organize the cold aggregate. During the conveying process, this prevents different batches or types of cold aggregate from mixing, ensuring the purity and consistency of the conveyed aggregate. This facilitates precise quality control of the aggregate in subsequent processing stages, improves the quality stability of the final product, and reduces problems such as uneven stress on the belt plate caused by disordered aggregate accumulation, further extending the service life of the belt plate.

[0037] Specifically, the belt plate includes, from bottom to top, a metal base plate 13, a tear-resistant layer 14, a load-bearing layer 15, a buffer layer 16, and a wear-resistant layer 17.

[0038] In this embodiment, the belt conveyor adopts a multi-layer structure design, comprising, from bottom to top, a metal base plate, a tear-resistant layer, a load-bearing layer, a buffer layer, and a wear-resistant layer. The metal base plate provides stable foundation support; the tear-resistant layer effectively prevents the belt conveyor from tearing when subjected to external impact or uneven local stress, enhancing the overall structural integrity of the belt conveyor; the load-bearing layer can withstand large tensile and compressive forces, ensuring that the belt conveyor does not undergo excessive deformation or breakage when conveying heavy-duty cold aggregates, thus guaranteeing the reliability of the conveying; the buffer layer can absorb the impact force when cold aggregates fall, reducing damage to the belt conveyor and other components, and reducing equipment operating noise; the wear-resistant layer significantly improves the wear resistance of the belt conveyor surface, extends the service life of the belt conveyor, and reduces maintenance costs and replacement frequency caused by wear.

[0039] Specifically, the tear-resistant layer is a polyester fiber mesh, the load-bearing layer is a polyester canvas, the cushioning layer is a polyurethane foam layer, and the abrasion-resistant layer is a natural rubber-styrene-butadiene rubber layer.

[0040] In this embodiment, the tear-resistant layer is made of polyester fiber mesh, which has good toughness and tensile strength, and can effectively disperse external forces at a low cost to prevent the expansion of tear cracks; the load-bearing layer is made of polyester canvas, which has good flexibility and cost-effectiveness while ensuring a certain strength, and is suitable for various medium conveying volume and distance working conditions; the buffer layer is made of polyurethane foam, which can effectively reduce the impact damage of cold aggregate to the belt plate and improve the impact resistance of the belt plate due to its excellent buffering performance; the wear-resistant layer is a natural rubber-styrene-butadiene rubber layer, which combines the good elasticity and wear resistance of natural rubber with the aging resistance and hardness of styrene-butadiene rubber. While ensuring the flexibility of the conveyor belt, it effectively resists the wear of cold aggregate, comprehensively improving the performance of the belt plate in all aspects, so that it can adapt to different cold aggregate conveying environments and requirements.

[0041] In actual production, the metal base plate and the polyester fiber mesh (tear-resistant layer) can be bonded together using adhesives. First, the surface of the metal base plate is pre-treated by grinding and degreasing, then an epoxy-rubber composite adhesive is used to bond it under certain pressure and curing conditions.

[0042] If both the polyester fiber mesh (tear-resistant layer) and the polyester canvas (load-bearing layer) are made of fabric, they can be connected by sewing, using high-strength fiber thread to tightly sew them together.

[0043] Hot melt adhesive can be used to bond the polyester canvas (load-bearing layer) and the polyurethane foam (cushioning layer). The hot melt adhesive is applied to the surface of the load-bearing layer, heated to melt it, and then bonded to the cushioning layer.

[0044] The polyurethane foam layer (buffer layer) and the natural rubber-styrene-butadiene rubber layer (wear-resistant layer) can be bonded by vulcanization. Under high temperature and the action of vulcanizing agent, the rubber molecular chains cross-link and are tightly bonded.

[0045] Specifically, the side plates of the bracket are also provided with adjustment mechanisms for adjusting the position of the driven roller.

[0046] In this embodiment, adjustment mechanisms for adjusting the position of the driven rollers are provided on both sides of the support side plate, facilitating the adjustment of the conveyor belt tension. By adjusting the position of the driven rollers, the elongation or slackness of the belt plates after prolonged use can be compensated, ensuring that the conveyor belt is always at a suitable tension. Appropriate tension ensures good meshing between the driven chain and the driving and driven rollers, reducing chain slippage, improving transmission efficiency, and avoiding problems such as increased equipment wear, increased energy consumption, and unstable conveying caused by excessively loose or tight belt plates. This guarantees the efficient and stable operation of the conveyor belt system and extends the service life of the equipment.

[0047] Specifically, the adjustment mechanism includes a bearing seat 19 that is slidably fitted with a guide step 18 on the side plate of the support and a long screw 20 connected to the bearing seat 19. The long screw 20 passes through a guide plate 21 on one side of the support side plate and is fixed by a nut 22. The driven roller is rotatably connected to the bearing seat at both ends.

[0048] In this embodiment, adjustment mechanisms for adjusting the position of the driven rollers are provided on both sides of the support side plate, facilitating the adjustment of the conveyor belt tension. By adjusting the position of the driven rollers, the elongation or slackness of the belt plates after prolonged use can be compensated, ensuring that the conveyor belt is always at a suitable tension. Appropriate tension ensures good meshing between the driven chain and the driving and driven rollers, reducing chain slippage, improving transmission efficiency, and avoiding problems such as increased equipment wear, increased energy consumption, and unstable conveying caused by excessively loose or tight belt plates. This guarantees the efficient and stable operation of the conveyor belt system and extends the service life of the equipment.

[0049] When adjusting, loosen the nut, push the bearing housing along the guide step to the appropriate position, and then tighten the nut.

[0050] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
