Description

Technical Field

[0001] This utility model relates to the field of material handling machine technology, and in particular to a high-efficiency wear-resistant scraper for a material handling machine. Background Technology

[0002] A material reclaimer is a specialized piece of equipment used for continuous material handling in bulk material yards. It also functions as a stacker, achieving high-efficiency operation through core components such as bucket wheels and slewing mechanisms. The primary function of a material reclaimer is continuous material handling, while also possessing stacking capabilities. It is suitable for storage yards in thermal power plants, ports, and other similar locations. Its core components include bucket wheel devices, slewing mechanisms, and traveling mechanisms. Through the coordinated operation of rotating material handling and a conveyor belt, it achieves efficient and continuous operation. A search revealed Chinese patent CN208199804U, which discloses a scraper reclaimer, comprising a main arm, a support arm, a chain, and a scraper. A support base is fixed to the bottom of the support arm, and the main arm is rotatably mounted on the support arm. A hydraulic lifting device is connected to the left end of the main arm. A drive shaft is mounted on the support arm, with a drive motor connected to one end. A drive wheel is fixed to the middle of the drive shaft, and a driven wheel is rotatably mounted at the front end of the main arm. The chain connects the drive wheel and the driven wheel. The middle of the scraper is fixed to the outside of the chain, and support rollers are installed on the inner sides of both ends of the scraper. The upper roller contacts the top of the main arm. This invention features a suspended chain, eliminating chain wear, reducing chain breakage, and significantly increasing chain lifespan. The chain-supported scraper is replaced with a scraper-supported chain, changing sliding friction to rolling friction, reducing energy consumption. The suspended shaft only drives the chain, reducing the shaft load and greatly decreasing the probability of shaft breakage. This further reduces energy consumption.

[0003] In actual use, this patent has the following drawbacks: After prolonged use, scrapers need to be replaced due to wear and tear. However, the scraper in this patent is fixedly mounted on the chain, which makes it inconvenient for workers to disassemble and install the scraper, increasing the inconvenience when replacing it. Utility Model Content

[0004] In the existing technology, scrapers need to be replaced due to wear after long-term use. However, the scraper in this patent is fixed on the chain, which makes it inconvenient for workers to disassemble and fix the scraper, increasing the inconvenience of scraper replacement. This utility model provides a high-efficiency wear-resistant scraper for a material handling machine.

[0005] The technical solution adopted by this utility model is: a high-efficiency wear-resistant scraper for a material handling machine, comprising a scraper body and a disassembly and assembly mechanism. The disassembly and assembly mechanism includes a fixed base, a support plate, and a bidirectional threaded rod. The fixed base has an installation cavity, and the support plate is fixedly installed in the installation cavity. The bidirectional threaded rod is rotatably installed between the support plates. Threaded slide rods are slidably installed at both ends of the installation cavity. A snap-fit ​​rod is fixedly installed at one end of the threaded slide rod. Both the threaded slide rod and the snap-fit ​​rod are threadedly connected to the bidirectional threaded rod. A turbine is fixedly installed on the periphery of the middle part of the bidirectional threaded rod. A worm gear is rotatably installed in the middle of the inner wall of the installation cavity, and the worm gear meshes with the turbine.

[0006] Furthermore, the fixed base has two insertion slots on one side, and two insertion blocks are fixedly installed on one side of the scraper body. The insertion blocks are inserted into the insertion slots, and a snap-fit ​​groove is provided on one side of the insertion block. The snap-fit ​​rod is movably inserted into the snap-fit ​​groove.

[0007] Furthermore, a limiting mechanism is provided on one side of the fixed base, and the limiting mechanism is connected to one end of the worm gear. The limiting mechanism includes a rotating shaft, a linear slide bar, and a polygonal insert.

[0008] Furthermore, a polygonal slot is provided on one side of the fixed base, and a rotating groove is provided on one side of the inner wall of the polygonal slot. The rotating shaft is rotatably installed in the rotating groove, and a linear sliding groove is provided at one end of the rotating shaft. The linear sliding rod is slidably installed in the linear sliding groove, and the polygonal plug is fixedly installed at one end of the linear sliding rod, and the polygonal plug is movably inserted into the polygonal slot.

[0018] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0019] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a high-efficiency wear-resistant scraper for a material handling machine.

[0020] The specific technical solution includes a scraper body 1 and a disassembly and assembly mechanism 2. The disassembly and assembly mechanism 2 includes a fixed base 5, a support plate 7, and a bidirectional threaded rod 8. The fixed base 5 has an installation cavity 6. The support plate 7 is fixedly installed in the installation cavity 6. The bidirectional threaded rod 8 is rotatably installed between the support plates 7. There are two support plates 7. Threaded slide rods 9 are slidably installed at both ends of the installation cavity 6. A snap-fit ​​rod 11 is fixedly installed at one end of the threaded slide rod 9. Both the threaded slide rod 9 and the snap-fit ​​rod 11 are threadedly connected to the bidirectional threaded rod 8. A turbine 12 is fixedly installed on the circumference of the middle part of the bidirectional threaded rod 8. A worm gear 13 is rotatably installed in the middle of the inner wall of the mounting cavity 6. The worm gear 13 meshes with the turbine 12. Two insertion slots 10 are opened on one side of the fixed seat 5. Two insertion blocks 3 are fixedly installed on one side of the scraper body 1. The insertion blocks 3 are inserted into the insertion slots 10. A snap-fit ​​slot 4 is opened on one side of the insertion blocks 3. The snap-fit ​​rod 11 is movably inserted into the snap-fit ​​slot 4. The worm gear 13 and the turbine 12 can facilitate the operator to drive the bidirectional threaded rod 8 to rotate.

[0021] Reference Figure 3 and Figure 4As shown, a limiting mechanism 14 is provided on one side of the fixed base 5. The limiting mechanism 14 is connected to one end of the worm gear 13. The limiting mechanism 14 includes a rotating shaft 15, a linear slide rod 17, and a polygonal plug 19. A polygonal slot is provided on one side of the fixed base 5. A rotating groove is provided on one side of the inner wall of the polygonal slot. The rotating shaft 15 is rotatably installed in the rotating groove. A linear slide groove 16 is provided at one end of the rotating shaft 15. The linear slide rod 17 is slidably installed in the linear slide groove 16. One end of the linear slide rod 17 is straight. The linear slide groove 16 is adapted to the linear slide rod 17. The polygonal plug 19 is fixedly installed at one end of the linear slide rod 17 and is movably inserted into the polygonal slot. One end of the rotating shaft 15 is fixedly connected to one end of the worm gear 13. A spring 18 is provided between the linear slide rod 17 and the linear slide groove 16. A slot 20 is provided on one side of the polygonal plug 19. Two slots 21 are provided on both sides of the inner wall of the slot 20. The slot 20 is movably inserted into the slot. A connector 22 is provided, with locking blocks 23 fixedly installed on both sides of one end of the connector 22. The locking blocks 23 correspond to the locking slots 21. The connector 22 can be removed and stored after use. By inserting the connector 22 and locking blocks 23 into the slot 20, and then rotating the connector 22 and locking blocks 23, the locking blocks 23 are rotated into the locking slots 21. Then, by pulling the connector 22 and locking blocks 23, the locking blocks 23 move through the locking slots 21, causing the polygonal plug 19 to move out of the polygonal plug. The slot is then connected to the plug 22 and the locking block 23, which drive the polygonal plug 19 to rotate. The rotation of the polygonal plug 19 can drive the rotating shaft 15 to rotate through the linear slide rod 17. The rotation of the rotating shaft 15 can drive the worm gear 13 to rotate. Conversely, by inserting the polygonal plug 19 into the polygonal slot and making the spring 18 provide tension to the polygonal plug 19, the polygonal plug 19 is stably inserted into the polygonal slot, thus limiting the rotation shaft 15 and the worm gear 13.

[0022] Reference Figure 5 As shown, the scraper body 1 includes a substrate 24, a wear-resistant plate 25, and a wear-resistant coating 26. The wear-resistant plate 25 is disposed on one side of the substrate 24, and the wear-resistant coating 26 is disposed on one side of the wear-resistant plate 25. The substrate 24 is high-manganese steel, and the wear-resistant plate 25 is high-chromium cast iron. The wear-resistant plate 25 is coated on the working surface of the substrate 24 by casting, explosive bonding, or hot rolling bonding. The wear-resistant coating 26 is tungsten carbide powder, which is coated on the working surface of the wear-resistant plate 25 by thermal spraying.

[0023] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, by releasing the limiting mechanism 14 from the worm gear 13, the limiting mechanism 14 drives the worm gear 13 to rotate. The rotation of the worm gear 13 drives the turbine 12 to rotate, and the rotation of the turbine 12 drives the bidirectional threaded rod 8 to rotate. The rotation of the bidirectional threaded rod 8 drives the two threaded slide rods 9 to move synchronously towards the center of the inner wall of the mounting cavity 6. When the two threaded slide rods 9 move towards the center of the inner wall of the mounting cavity 6, they drive the two locking rods 11 to move synchronously towards the center of the inner wall of the mounting cavity 6. This causes the locking rods 11 to disengage from the locking groove 4 of the insertion block 3 and retract into the mounting cavity 6, releasing the fixing limitation on the insertion block 3. Then, by pulling the scraper body 1, the scraper body 1 can drive the insertion block 3 to disengage from the insertion groove 10, thereby completing the disassembly of the scraper body 1. During installation, the scraper body 1 can be fixedly installed by reversing the above steps.
