Description

Technical Field

[0001] This invention relates to the field of material transfer technology, specifically to a material transfer conveyor belt for stockyards. Background Technology

[0002] As a dedicated site for civil engineering, the storage yard is mainly responsible for the loading, unloading, transfer, and storage of materials, equipment, and other supplies. It requires the use of conveyor belts for loading, unloading, and transfer of materials.

[0003] For example, a multi-point unloading belt conveyor for material handling, disclosed in CN109850542A, includes a base, a support plate fixedly installed on the top of the base, an installation box fixedly installed on the top of the support plate, a first rotating shaft movably mounted inside the installation box, a first drum located inside the installation box movably mounted on the outer wall of the first rotating shaft, a second rotating shaft movably mounted on the other side of the installation box, a second drum located inside the installation box fixedly mounted on the outer wall of the second rotating shaft, a motor fixedly mounted on one side of the support plate, and a third drum fixedly mounted on the outer wall of the motor output shaft.

[0004] In existing technologies, cleaning scrapers have a simple structure, mostly fixed-type flat scrapers or scrapers made of a single material. They cannot flexibly switch to adapt to the viscosity of the material. When dealing with highly viscous materials, due to insufficient hardness of the scraper blade material or the lack of adhesive-breaking design, the material easily forms a tight adhesive layer on the blade surface. This not only fails to completely remove residue from the belt surface but also causes the adhered material to spill during the return trip of the belt. For medium-viscous materials, if a hard scraper adapted for highly viscous materials is used, the rigid friction between the blade and the belt surface is too strong, which will quickly wear down the belt cover rubber, shorten the belt's service life, and may also leave scratches on the belt surface, which will increase the probability of subsequent material adhesion and affect the normal operation of the belt. Summary of the Invention

[0005] The purpose of this invention is to provide a material transfer conveyor belt for stockyards, which solves the problem mentioned in the background art that the cleaning scraper structure is simple, mostly fixed type flat scraper or single material scraper, and cannot flexibly switch the appropriate scraper according to the viscosity of the material.

[0007] Preferably, a guide rod is slidably connected to the bottom side of the sliding sleeve, the other end of the guide rod is fixedly connected to the inner side of the mounting frame, and a compensating spring is sleeved on the outside of the guide rod.

[0008] Preferably, sliding rods are fixedly connected to both sides of the mounting plate, and sliding grooves are provided on one side of the first scraper and one side of the second scraper, with the inside of the sliding grooves slidably connected to the outside of the sliding rods.

[0009] Preferably, the first cleaning component includes a first connecting shaft and a second connecting shaft. The first connecting shaft is rotatably connected to the collection box. Both ends of the first connecting shaft pass through the side wall of the collection box. A cleaning roller is fixedly connected to the outside of the first connecting shaft.

[0010] Preferably, the second connecting shaft is rotatably connected to the collection box, the second connecting shaft is externally fixedly connected to the brush roller, one end of the second connecting shaft passes through the side wall of the collection box, and a second belt assembly is installed between one end of the second connecting shaft and the first connecting shaft.

[0011] Preferably, the feeding mechanism includes a top plate, which is fixedly connected to the top of the belt conveyor body. An elastic component is installed on the bottom side of the top plate. The elastic component includes a fixed plate. One end of two fixed plates is fixedly connected to the top plate. A connecting rod is rotatably connected between the two fixed plates. A fixed frame is fixedly connected to both ends of the connecting rod. A feeding scraper is fixedly connected to one side of the fixed frame.

[0012] Preferably, a steering rod is rotatably connected to one side of each of the two fixed plates, a steering plate is movably connected to the outside of the steering rod, and one end of the steering plate is rotatably connected to the outside of the connecting rod.

[0013] Preferably, a compression spring is installed between the steering plate and the steering rod, and the compression spring is sleeved on the outside of the steering rod.

[0014] Preferably, adjustment components are installed on both sides of the feeding scraper. The adjustment components include a first electric push rod, one side of which is fixedly connected to one side of the feeding scraper. A push block is fixedly connected to one end of the first electric push rod, and an adjustment plate is fixedly connected to one end of the push block.

[0015] Preferably, the scraper is provided with a guide groove, and a sliding block is slidably connected to the inner side of the guide groove. One end of the sliding block is fixedly connected to one side of the adjusting plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, when the conveyor belt carries the material to the switching component, the sliding sleeve slides along the guide rod. The compensating spring, through its elastic force, causes the mounting rod to drive the switching component to adapt to the vibration or deformation of the belt, maintaining the fit with the bottom side of the belt. The second electric push rod pushes the telescopic rod to rotate, realizing the smooth switching between the first scraper and the second scraper. By using the wedge force of the V-shaped scraper to peel off different viscous materials, the adaptability and cleaning stability of the cleaning to different viscous materials are improved. At the same time, the targeted V-shaped scraper design improves the scraping efficiency and reduces material residue on the belt surface.

[0018] 2. In this invention, while the drive assembly drives the belt conveyor to transport materials, the first belt assembly drives the first connecting shaft to rotate, and the cleaning roller rotates synchronously. The spiral scraper on its surface can guide the scraped residual material to the collection box along the spiral direction to scrape off the residual material on the belt surface. At the same time, it drives the second connecting shaft to rotate, and the brush roller rotates synchronously. The bristles of the brush roller penetrate into the fine texture of the belt surface to brush away the residual fine particles. The brush roller brushes away the residual fine particles or adhesive layer on the belt surface. Through the two-stage cleaning of scraping and brushing, the surface material is completely removed, and the cleaning effect is improved.

[0019] 3. In this invention, when the material impacts the scraper, the steering plate slides along the steering rod and causes the compression spring to deform. The spring force buffers the impact of the material and drives the scraper to rotate, avoiding material splashing and scraper damage. At the same time, the first electric push rod works to push the push block to move, which in turn drives the adjustment plate to move and adjust the effective scraper width, so that the material is discharged evenly and the stability of the belt conveyor is guaranteed.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Refer to Figure 1 - Figure 9 As shown: A material transfer conveyor belt for stockyards is used for material transfer in stockyards. Through the integrated design of conveying, unloading adjustment and belt cleaning, it solves the problems of material deviation due to uneven loading and the difficulty in cleaning materials adhering to the belt.

[0032] I. Technical solutions and working principles of each core component.

[0033] (i) The feeding mechanism 2 buffers impact, adjusts the feeding width, and prevents belt misalignment due to uneven load. When the material falls and impacts the feeding scraper 24, it drives the fixed frame 226 and connecting rod 223 to rotate, thereby causing the steering plate 225 to slide along the steering rod 222 and the compression spring 224 to deform. The spring force is used to offset the impact energy, preventing the scraper and belt from being damaged by hard impact. Then the spring rebounds and drives the feeding scraper 24 to reset, ensuring feeding stability. According to the material conveying volume, the first electric push rod 235 extends and retracts to push the push block 234, causing the sliding block 232 to slide along the guide groove 231, thereby driving the adjusting plate 233 to move and change the bottom opening width of the feeding scraper 24. Finally, the material is evenly distributed on the belt surface, preventing the belt from misaligning due to uneven load.

[0034] (ii) Cleaning mechanism 3: Adaptive cleaning of sticky materials and secondary deep cleaning. Through a two-step process of targeted scraper peeling and secondary deep cleaning, the sticky materials on the belt surface are thoroughly cleaned. The core is divided into two stages.

[0035] 1. Targeted scraper peeling, adaptable to different viscous materials: Based on the difference in material viscosity, the second electric push rod 346 drives the telescopic rod 347 to rotate, causing the first scraper 341 and the second scraper 342 to switch. The first scraper 341 uses a tungsten carbide cutting edge, which is suitable for high-viscosity materials, while the second scraper 342 uses a polyurethane-coated cutting edge, which is suitable for medium-viscosity materials. Both are V-shaped structures, which use wedge force to forcibly peel the material from the belt surface, improving scraping efficiency. The peeled material falls into the collection box 33. When the belt conveyor 1 moves the material to the switching component 34, the switching component 34 is pushed by the material. The compensation spring 353 pushes the mounting rod 351 through elastic force, causing the switching component 34 to adapt to the vibration or deformation of the belt, always maintaining a tight fit with the bottom side of the belt, avoiding cleaning omissions due to loose fit.

[0036] 2. Secondary deep cleaning to remove residual fine particles: The drive component 4 drives the first connecting shaft 321 to rotate through the first belt assembly 31, so that the cleaning roller 325 rotates synchronously to scrape off the residual material on the belt surface that has not been completely peeled off by the scraper. The brush roller 323 rotates synchronously to brush and clean the fine particles or adhesive layers adhering to the belt surface, remove the residual material on the belt, and ensure the cleaning effect.

[0037] (III) Drive component 4, power coordination and synchronous linkage: directly drives the belt conveyor body 1 to operate, and drives the material to be conveyed along the belt. At the same time, the power is transmitted to the first cleaning component 32 through the first belt assembly 31, so that the cleaning roller 325 and the brush roller 323 rotate synchronously, realizing the synchronous operation of material conveying and belt cleaning.

[0038] II. Overall Workflow.

[0039] 1. Start-up and power transmission: When the drive component 4 is started, it drives the belt conveyor 1 to rotate on the one hand, and provides power to the cleaning mechanism 3 through the first belt assembly 31 on the other hand;

[0040] 2. Material feeding adjustment and buffering: When the material falls and impacts the feeding scraper 24, the elastic component 22 buffers the impact through the deformation of the compression spring 224 and then returns to its original position; at the same time, the first electric push rod 235 drives the adjustment plate 233 to move, adjusting the feeding width so that the material is evenly distributed on the belt surface.

[0041] 3. Belt cleaning and scraper peeling: The belt carries the material to the switching component 34. The compensation component 35 ensures that the scraper is in contact with the belt. The second electric push rod 346 switches the matching scraper and peels off the material through V-shaped wedge force. The collection box 33 receives the material.

[0042] 4. Deep cleaning and two-stage coordination: The drive component 4 drives the cleaning roller 325 to scrape off residue and the brush roller 323 to scrub the belt through the first belt assembly 31 and the second belt assembly 324, thus completing a comprehensive cleaning.

[0043] Example 2: Refer to Figure 1 - Figure 9As shown: A material transfer conveyor belt for a stockpile includes a conveyor body 1, a drive assembly 4 installed on one side of the conveyor body 1, a feeding mechanism 2 installed above the conveyor body 1, and a cleaning mechanism 3 installed at the bottom of the conveyor body 1. The cleaning mechanism 3 includes a first belt assembly 31, a first cleaning assembly 32, and a collection box 33. A compensation assembly 35 is installed inside the collection box 33. The compensation assembly 35 includes a mounting frame 352, the outer side of which is fixedly connected to the inner side of the collection box 33. Sliding sleeves 355 are slidably connected to both sides of the mounting frame 352. A compensation spring 353 is installed between the sliding sleeves 355 and the mounting frame 352. An mounting rod 351 is installed between the two sliding sleeves 355. A switching assembly 34 is installed above the mounting rod 351. The switching assembly 34 includes a mounting plate 345, the bottom side of which is fixedly connected to the middle of the mounting rod 351. A telescopic rod 347 is rotatably connected to the middle of the 5. The other ends of the two telescopic rods 347 are rotatably connected to the first scraper 341 and the second scraper 342, respectively. A second electric push rod 346 is rotatably connected to the outside of one of the telescopic rods 347. The other end of the second electric push rod 346 is rotatably connected to the middle of the mounting plate 345. The cleaning mechanism 3, through the cooperation of the first cleaning component 32 and the switching component 34, performs targeted cleaning of the sticky materials on the belt conveyor body 1. A guide rod 354 is slidably connected to the bottom side of the sliding sleeve 355. The other end of the guide rod 354 is fixedly connected to the inside of the mounting frame 352. A compensating spring 353 is sleeved on the outside of the guide rod 354. Sliding rods 343 are fixedly connected to both sides of the mounting plate 345. A sliding groove 344 is opened on one side of the first scraper 341 and the second scraper 342. The inside of the sliding groove 344 is slidably connected to the outside of the sliding rod 343.

[0044] In this embodiment, the mounting frame 352 is fixed inside the collection box 33. When the conveyor belt 1 carries the material adhering to it to the switching component 34, it pushes the switching component 34 to move. The sliding sleeve 355 slides along the guide rod 354 to compensate for the elastic force of the spring 353, so that the mounting rod 351 drives the switching component 34 to adapt to the vibration or deformation of the conveyor belt 1, maintaining the fit between the switching component 34 and the bottom side of the conveyor belt 1. This ensures that the scraper of the switching component 34 forms a uniform contact surface with the bottom side of the conveyor belt 1, preventing excessive wear of the scraper blade due to excessive local contact, and preventing dead corners for material cleaning due to excessively loose contact. Depending on the viscosity of the material conveyed by the conveyor belt 1, the second electric push rod 346 drives the two telescopic rods 347 to rotate, driving the first scraper. The first scraper 341 and the second scraper 342 move, and the sliding rod 343 slides inside the sliding groove 344 to ensure smooth scraper switching, thereby realizing the switching between the first scraper 341 and the second scraper 342 to adapt to different viscous materials. The first scraper 341 has a tungsten carbide cutting edge for high-viscosity materials, and the second scraper 342 has a polyurethane-coated cutting edge for medium-viscosity materials. Both the first scraper 341 and the second scraper 342 are V-shaped scrapers. Through the wedge force, they can quickly break the bonded structure and completely peel the material off the belt surface. They can also reduce the contact area between the cutting edge and the belt, reduce wear and tear, and improve scraping efficiency. The collection box 33 receives the scraped material, prevents the material from scattering, reduces the amount of subsequent cleaning work, and realizes material recycling and reuse, reducing resource waste.

[0045] Example 3: Figure 2 and Figure 4 As shown, the first cleaning component 32 includes a first connecting shaft 321 and a second connecting shaft 322. The first connecting shaft 321 is rotatably connected to the collection box 33. Both ends of the first connecting shaft 321 pass through the side wall of the collection box 33. A cleaning roller 325 is fixedly connected to the outside of the first connecting shaft 321. One end of the first connecting shaft 321 is connected to the shaft end of the drive component 4 via a first belt assembly 31. The second connecting shaft 322 is rotatably connected to the collection box 33. The outside of the second connecting shaft 322 is fixedly connected to a brush roller 323. One end of the second connecting shaft 322 passes through the side wall of the collection box 33. A second belt assembly 324 is installed between one end of the second connecting shaft 322 and the first connecting shaft 321.

[0046] In this embodiment, the drive assembly 4 includes a working motor, a conveyor roller, and a roller shaft. The first belt assembly 31 and the second belt assembly 324 each include two pulleys and a conveyor belt. While the drive assembly 4 drives the belt conveyor body 1 to transport materials, the first belt assembly 31 drives the first connecting shaft 321 to rotate, causing the cleaning roller 325 to rotate synchronously. The cleaning roller 325 has spiral scrapers on its surface, which guide the scraped residual material along the spiral direction to the collection box 33, preventing material from remaining on the surface of the cleaning roller 325. The material accumulates and forms clumps, ensuring that the cleaning roller 325 maintains its scraping ability to remove residual material from the belt surface. The first connecting shaft 321 drives the second connecting shaft 322 to rotate through the second belt assembly 324, and the brush roller 323 rotates synchronously. The bristles of the brush roller 323 are made of high-elasticity nylon filaments, which penetrate deep into the fine texture of the belt surface to brush away residual fine particles. When in contact, the elastic deformation avoids scratching the surface. The brush roller 323 brushes away residual fine particles or adhesive layers on the belt surface. Through the two-stage cleaning of scraping and brushing, the surface material is thoroughly removed, improving the cleaning effect.

[0047] Example 4: According to Figure 8 and 9 As shown, the feeding mechanism 2 includes a top plate 21, which is fixedly connected to the top of the conveyor belt body 1. An elastic component 22 is installed on the bottom side of the top plate 21. The elastic component 22 includes fixed plates 221. One end of the two fixed plates 221 is fixedly connected to the top plate 21. A connecting rod 223 is rotatably connected between the two fixed plates 221. A fixed frame 226 is fixedly connected to both ends of the connecting rod 223. A feeding scraper 24 is fixedly connected to one side of the fixed frame 226. A steering rod 222 is rotatably connected to one side of each of the two fixed plates 221. A steering plate 225 is movably connected to the outside of the steering rod 222. One end of the steering plate 225 is rotatably connected to the outside of the connecting rod 223. The steering plate 225 and the... A compression spring 224 is installed between the steering rods 222, and the compression spring 224 is sleeved on the outside of the steering rods 222; an adjustment assembly 23 is installed on both sides of the scraper 24, the adjustment assembly 23 includes a first electric push rod 235, one side of the first electric push rod 235 is fixedly connected to one side of the scraper 24, one end of the first electric push rod 235 is fixedly connected to a push block 234, one end of the push block 234 is fixedly connected to an adjustment plate 233, one side of the adjustment plate 233 overlaps with one side of the scraper 24; a guide groove 231 is opened on the scraper 24, a sliding block 232 is slidably connected to the inner side of the guide groove 231, and one end of the sliding block 232 is fixedly connected to one side of the adjustment plate 233.

[0048] In this embodiment, the top plate 21 is fixed to the top of the conveyor body 1, and the fixing plate 221 is connected to the connecting rod 223. When the material impacts the scraper 24, the steering plate 225 slides along the steering rod 222 and causes the compression spring 224 to deform. The elastic force of the compression spring 224 can buffer the impact. The fixing plate 221 is provided with an arc-shaped limiting block, which can limit the maximum rotation angle of the connecting rod 223 to prevent the scraper 24 from deflecting excessively due to excessive material impact, avoid the material from deviating from the belt conveying range, and reduce material spillage loss. Then, the scraper 24 is driven to rotate. The first electric push rod 235 extends and retracts to push the push block 234 to move. The push block 234 slides inside the guide groove 231, which drives the adjusting plate 233 to move along the guide groove 231 to adjust the opening width at the bottom of the scraper 24, thereby adjusting the effective feeding width. For large-diameter materials, the opening width can be increased to avoid material blockage. For small-diameter materials, the opening width can be decreased to ensure that the material is evenly distributed on the belt surface, so that the material is evenly distributed for feeding.

[0049] The operating method and working principle of this device are as follows: After the drive component 4 is started, it drives the belt conveyor 1 to run on the one hand, and makes the feeding mechanism 2 and the cleaning mechanism 3 work synchronously on the other hand. When the material moves to impact the feeding scraper 24, the steering plate 225 slides along the steering rod 222 and the compression spring 224 deforms to buffer the impact, so as to avoid the feeding scraper 24 and the belt conveyor 1 from being deformed or damaged due to hard impact. Then the compression spring 224 drives the feeding scraper 24 to rotate, ensuring that the feeding scraper always stays in the preset feeding guide position. The first electric push rod 235 extends and retracts to push the push block 234, which drives the adjusting plate 233 to move and adjust the bottom opening width of the feeding scraper 24, so that the material forms a uniformly distributed material layer on the surface of the belt conveyor 1, which not only avoids uneven load and deviation, but also ensures the uniformity of material feeding.

[0050] When the conveyor belt 1 carries the material to the switching component 34, the mounting frame 352 is fixed inside the collection box 33. The switching component 34 moves under the push of the material, and the sliding sleeve 355 slides along the guide rod 354. The compensation spring 353 will adaptively extend and retract according to the vibration amplitude or deformation of the belt, so that the mounting rod 351 drives the switching component 34 to adapt to the vibration or deformation of the belt. The elastic force pushes the mounting rod 351 to drive the switching component 34 to follow the belt movement in real time, ensuring that the scraper blade edge is in contact with the bottom side of the belt. Even if the belt fluctuates slightly, no cleaning dead corner will be generated. The second electric push rod 346 pushes... The telescopic rod 347 rotates to switch between the first scraper 341 and the second scraper 342. During the switching process, the sliding rod 343 slides along the sliding groove 344 to ensure a stable switching path between the first scraper 341 and the second scraper 342. The tungsten carbide cutting edge of the first scraper 341 can cut the adhesion between highly viscous materials and the belt. The polyurethane-coated cutting edge of the second scraper 342 can avoid scratching the belt. Both of them have a 30-45° V-shaped structure, which can completely peel the material from the belt surface through wedge force. Finally, the scraped material falls into the collection box 33 under the action of gravity for belt surface cleaning.

[0051] Subsequently, the drive assembly 4 drives the first connecting shaft 321 to rotate via the first belt assembly 31. The cleaning roller 325 rotates synchronously to scrape off the residual material on the belt surface. The spiral scraper can guide the scraped residual material to the collection box 33 along the spiral direction to prevent the material from accumulating and clumping on the surface of the cleaning roller 325. The first connecting shaft 321 drives the second connecting shaft 322 to rotate via the second belt assembly 324. The brush roller 323 rotates synchronously. The bristles can penetrate into the fine texture of the belt surface to brush off the fine particles or adhesive layers remaining on the belt surface, completing the dual cleaning of scraping and brushing, ensuring the long-term stability and service life of the belt.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
