Description

Technical Field

[0001] This utility model relates to the field of scraper technology for material handling machines, and more specifically, to a scraper structure for a material handling machine. Background Technology

[0002] Scraper reclaimers, also known as chain scraper conveyors, are commonly used for horizontal or inclined conveying of powdery or granular materials. In operation, numerous scraper blades are connected to a conveyor chain at the bottom of the storage silo. As the conveyor chain moves, it drives the scraper blades, which scrape up the material from the bottom of the silo and push it forward. The material scraped off by the scraper blades then proceeds to the next processing step.

[0003] Most existing scraper blades of material reclaimers are installed with bolts, which makes the installation and disassembly process cumbersome. Furthermore, a large number of scraper blades are often installed and replaced on material reclaimers depending on the material being reclaimed, which increases the workload and reduces work efficiency.

[0004] A search revealed that Chinese Patent No. CN221987325U discloses a scraper structure for a material handling machine. This utility model can quickly lock and unlock the scraper body, making the disassembly and replacement of the scraper body more convenient, reducing the workload when replacing multiple scraper bodies, and effectively saving work efficiency.

[0005] However, in actual use, after the scraper scrapes the material, the material is squeezed inside the scraper due to the scraping and squeezing process. As the scraper rotates and discharges the material, the material will remain inside the scraper, affecting the material discharge speed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a scraper structure for a material handling machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A scraper structure for a material handling machine includes a scraper with multiple protruding teeth fixedly connected to one side. A stop bar is fixedly connected to the inner side of the scraper, and a dispersing mechanism is provided on the inner side of the scraper. The dispersing mechanism includes three fixed frames, one side of which is fixedly connected to the inner side of the scraper. A baffle is hinged to the outer side of the fixed frame. Multiple openings are provided on the inner side of the baffle. A counterweight rod is fixedly connected to one side of the baffle. Multiple grooves are provided on the inner side of the counterweight rod. A spring is fixedly connected to the inner side of the groove. A push block is fixedly connected to one end of the spring. The outer side of the push block is slidably connected to the inner side of the counterweight rod. A support block is fixedly connected to one side of the push block. The outer side of the support block is slidably connected to the inner side of the push block. Multiple inserts are inserted into one side of the scraper. An insert rod is fixedly connected to one side of each insert. A screw is inserted into the outer side of each insert. The outer side of the screw is threadedly connected to the inner side of the scraper. An auxiliary vibration mechanism is provided at the top of the scraper.

[0009] By adopting the above technical solution, the material can be pushed by the deflection of three baffles, allowing the material inside the scraper to be conveyed out quickly, thereby increasing the material discharge speed inside the scraper.

[0010] As a further description of the above technical solution: the auxiliary vibration mechanism includes a connecting plate, the bottom of the connecting plate is fixedly connected to the top of the scraper, an arc-shaped groove is opened on one side of the connecting plate, a rotating shaft is fixedly connected to one side of the connecting plate, a connecting frame is hinged to the outside of the rotating shaft, a plurality of screws are threaded to the outside of the connecting frame, a plurality of rotating shafts are fixedly connected to the bottom of the connecting frame, and the outside of the rotating shafts is slidably connected to the inside of the arc-shaped groove.

[0011] By adopting the above technical solution: the connecting plate and the connecting frame rotate through the first rotating shaft, and the second rotating shaft is deflected up and down to a certain extent through the arc groove, so that after the scraper rotates to the highest point, the second rotating shaft will be deflected up and down on the inner side of the arc groove, so that the scraper can vibrate to a certain extent, thereby allowing the material inside the scraper to be discharged.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a dispersing mechanism, compared with the existing technology, multiple rods are used to disperse and scrape the material, so that the material can be quickly scraped into the inside of the scraper. Through the deflection of three baffles on the inside of the scraper, the material gathered inside the scraper can be quickly pushed out of the scraper by the baffles, thereby improving the scraper's ability to quickly scrape and discharge materials.

[0014] 2. By setting up an auxiliary vibration mechanism, compared with the existing technology, the deflection of the arc groove on the outside of the connecting frame allows the scraper to rotate and be conveyed to the top. After rotating, it will generate a certain vibration, which will cause the material inside the scraper to be subjected to a vibration and loosening force, thus avoiding excessive adhesion of the material on the inner wall of the scraper.

[0022] 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.

[0023] The embodiments disclosed in this application are as follows: Figure 1-6The scraper structure of the material handling machine shown includes a scraper 1, with multiple teeth 2 fixedly connected to one side of the scraper 1, a stop bar 4 fixedly connected to the inner side of the scraper 1, and a dispersing mechanism provided on the inner side of the scraper 1. The dispersing mechanism includes three fixed frames 5, one side of the fixed frame 5 is fixedly connected to the inner side of the scraper 1, and a baffle 6 is hinged to the outer side of the fixed frame 5. Multiple openings 7 are provided on the inner side of the baffle 6, and a counterweight rod 8 is fixedly connected to one side of the baffle 6. Multiple grooves 9 are provided on the inner side of the counterweight rod 8, and a spring 10 is fixedly connected to the inner side of the groove 9. A push block 11 is fixedly connected to one end of the spring 10, and the outer side of the push block 11 slides against the inner side of the counterweight rod 8. The push block 11 is fixedly connected to one side of a support block 12, and the outer side of the support block 12 is slidably connected to the inner side of the push block 11. Multiple insert blocks 14 are inserted into one side of the scraper 1, and insert rods 15 are fixedly connected to one side of the insert blocks 14. Screws 16 are inserted into the outer side of the insert blocks 14, and the outer side of the screws 16 is threadedly connected to the inner side of the scraper 1. An auxiliary vibration mechanism is provided at the top of the scraper 1. Multiple insert rods 15 are used to scrape the material, and the material is deflected by the three baffles 6 and the counterweight rod 8 inside the scraper 1 under the action of gravity, so that the three baffles 6 can assist in pushing the material inside the scraper 1 during the feeding process.

[0024] Reference Figure 2 and Figure 5 As shown, the auxiliary vibration mechanism includes a connecting plate 17. The bottom of the connecting plate 17 is fixedly connected to the top of the scraper 1. An arc-shaped groove 18 is provided on one side of the connecting plate 17. A rotating shaft 19 is fixedly connected to one side of the connecting plate 17. A connecting frame 20 is hinged to the outside of the rotating shaft 19. Multiple screws 21 are threaded to the outside of the connecting frame 20. Multiple rotating shafts 22 are fixedly connected to the bottom of the connecting frame 20. The outside of the rotating shafts 22 is slidably connected to the inside of the arc-shaped groove 18. By sliding the rotating shafts 22 up and down inside the arc-shaped groove 18, the scraper 1 will deflect and vibrate once through the rotating shaft 19 during the process of rotating from the opening facing upward to the opening facing downward. This causes the material adhering to the inner wall of the scraper 1 to be dispersed by vibration, thereby reducing the adhesion of the material inside the scraper 1.

[0025] The working principle of this utility model is as follows: The transmission belt of the material handling machine drives the connecting frame 20 to rotate via the rotating shaft 19, connecting plate 17, and multiple scrapers 1. The rotation of the scrapers 1 causes multiple protruding teeth 2 on one side of the scraper 1 to scrape the material. The multiple protruding teeth 2 and multiple insert rods 15 on one side of the scraper 1 apply pressure to the material, allowing it to be dispersed. Then, under the rotation of the scraper 1, the material can enter the interior of the scraper 1. After entering the interior of the scraper 1, the material will squeeze the three baffles 6 on the inner side of the scraper 1, causing the counterweight rods 8 on one side of the baffles 6 to contact the inner wall of the scraper 1. When the baffles 6 receive pressure, the support blocks 12 on one side of the three counterweight rods 8 will squeeze the multiple springs 10 inside the counterweight rods 8, causing the springs 10 to... After the material is contracted, the scraper 1 loaded with material rotates upwards, so that the opening of the scraper 1 faces downwards. During the upward rotation of the scraper 1, the scraper 1 and the connecting plate 17 slide on the outside of the rotating shaft 22 under the action of gravity through the arc groove 18 on the inner side of the connecting plate 17. This causes the scraper 1 to vibrate. During the vibration, the material inside the scraper 1 falls downwards from the inside of the scraper 1 onto the conveyor belt. At the same time, the three baffles 6 inside the scraper 1 push the push block 11 and the support block 12 through multiple springs 10 under the action of gravity, so that the scraper 1 can carry the material away from the inner wall of the scraper 1, allowing the material to fall quickly from the inside of the scraper 1.
