Description

Technical Field

[0001] This utility model relates to the field of feeding hoppers, and in particular to a feeding hopper device that prevents falling. Background Technology

[0002] Currently, the most commonly used structural forms of hoppers are cylindrical hoppers with spiral grooves and conical hoppers. As auxiliary equipment in the conveying system, they play a role in connecting and coordinating the crane and belt conveyor system.

[0003] Related technology can be found in Chinese patent application CN221252468U, which discloses an aquatic feed hopper for preventing adhesion. The hopper includes a main body with a support frame at its bottom. Electric telescopic rods are installed on both sides of the top of the support frame, and each telescopic rod has a limiting guide rod at its top. A lifting ring is fitted around the limiting guide rod. Through the lifting ring, positioning rods, and through holes, the feed hopper facilitates the movement of a striking rod towards the target block. The attraction between a first and second magnet causes the striking rod to impact the target block, resulting in synchronous vibration of the outer wall of the feed hopper at multiple angles and points. This vibration causes the fish feed inside to fall downwards, reducing adhesion. Furthermore, the diverse positions of the target block result in a wider vibration range and better overall effect.

[0004] Regarding the aforementioned technologies, the feed hopper is usually connected to the processing device, such as a crusher or pulverizer. Since the feed hopper is in an open state and there is no obstruction around it, when the operator is feeding materials, it is easy for the operator to fall into the feed hopper, causing injury to the operator, resulting in low feeding safety. Utility Model Content

[0005] To improve the safety of feeding hoppers, this application provides a device for preventing falling feeding hoppers.

[0006] This application provides a fall-prevention feeding hopper device, which adopts the following technical solution:

[0007] A fall-prevention feeding hopper device includes a feeding hopper, which is vertically arranged. A first baffle is fixed to one side of the upper end of the feeding hopper along the length direction. The first baffle is vertically arranged. Second baffles are fixed to both sides of the upper end of the feeding hopper along the width direction. The second baffles are vertically arranged. A cover plate is fixed to the upper end of the second baffles to seal the opening between the first baffle and the second baffle. Several support plates are fixed inside the feeding hopper. The support plates are located at the upper end of the feeding hopper. A fall-prevention net plate is provided at the upper end of the support plates. A cylinder made of elastic material is provided vertically at the upper end of the support plates. Several cylindrical rods are fixed to the lower end of the fall-prevention net plate. The cylindrical rods are vertically arranged and correspond one-to-one with the cylinders. A circumferential groove is opened on the inner side of the cylinder. Several semi-circular blocks are provided circumferentially at the lower end of the cylindrical rods. The semi-circular blocks are adapted to the circumferential grooves. When the cylindrical rods are located inside the cylinders, the semi-circular blocks are located inside the circumferential grooves.

[0008] By adopting the above technical solution, the first baffle, the second baffle, and the cover plate work together to shield the upper end of the feed hopper. The support plate is used to support the anti-fall net plate. When the anti-fall net plate is placed on the support plate, the cylindrical rod is located inside the cylinder, and the semi-circular block fits into the annular groove to fix the anti-fall net plate. When the operator feeds the feed hopper, the anti-fall net plate can reduce the probability of the operator falling into the feed hopper and improve the safety of feeding the feed hopper.

[0009] Optionally, the second baffle is inclined from bottom to top along the side away from the first baffle, pointing towards the first baffle.

[0010] By adopting the above technical solution, the operator's body is in an inclined position when adding materials, and the inclined setting of the second baffle helps to improve the convenience of adding materials for the operator.

[0011] Optionally, both the upper end of the first baffle and the upper end of the cover plate are connected to an air extraction pipe, and an air extraction fan is installed inside the air extraction pipe.

[0012] By adopting the above technical solution, the air extractor removes floating objects from the air extraction pipe during the feeding process, which helps to reduce the obstruction of floating objects to operators and improves the feeding efficiency.

[0013] Optionally, a limiting plate is fixedly provided on the side of the second baffle away from the first baffle. The limiting plate is located between the two second baffles, and the lower end of the limiting plate is fixedly connected to the upper end of the feed hopper.

[0014] By adopting the above technical solution, the limiting plate is used to limit the fall protection net plate, reducing the probability of the fall protection net plate falling from the upper end of the feed hopper and improving the safety of feeding the feed hopper.

[0015] Optionally, the lower end of the cylindrical rod is provided with a plurality of first grooves along the circumference, and a first spring is provided in the first groove. The first spring is horizontally set, and the end of the first spring away from the cylindrical rod is fixedly connected to the semicircular block. In its natural state, the first spring pushes the semicircular block away from the cylindrical rod.

[0016] By adopting the above technical solution, during the separation process of the fall arrest net and the support plate, the semicircular block is located in the groove. When the cylindrical rod separates from the cylinder, the first spring pushes the semicircular block to move away from the cylindrical rod, which improves the convenience of disassembling the fall arrest net.

[0017] Optionally, impact blocks are fixed on both sides of the feed hopper along its length. The impact blocks are located outside the feed hopper. Guide rods are vertically hinged on both sides of the feed hopper along its length. Each guide rod corresponds to an impact block and is located below the impact block. The guide rods are inclined from bottom to top along the direction from the feed hopper to the impact block. A second spring is provided between the guide rod and the feed hopper. In its natural state, the second spring drives the guide rod to move closer to the feed hopper. A striking block is fixed at the upper end of the guide rod. The side of the striking block closest to the feed hopper is in contact with the impact block. A driving device is provided at the upper end of the impact block to drive the striking block away from the impact block.

[0018] By adopting the above technical solution, the driving device drives the striking block away from the impacted block, and the second spring drives the guide rod to approach the feed hopper, thereby causing the striking block to collide with the impacted block. When the material accumulates in the feed hopper, the contact between the striking block and the impacted block generates vibration in the feed hopper, allowing the material to fall smoothly into the next processing step, thus improving the convenience of feeding.

[0019] Optionally, the driving device includes two fixed blocks, a support rod, and a handle. The two fixed blocks are fixedly connected to both sides of the upper end of the block to be struck along the length direction. Both fixed blocks are vertically arranged. The support rod is located between the two fixed blocks and is horizontally arranged along the width direction of the block to be struck. The support rod is rotatably connected to the fixed blocks. The handle passes through the fixed blocks and is fixedly connected to one end of the support rod along the length direction. The handle is rotatably connected to the fixed blocks. Several push plates are fixedly arranged on the support rod circumferentially. When the push plate is located directly below the support rod, the end of the push plate away from the support rod abuts against the striking block.

[0020] By adopting the above technical solution, the fixed block supports the support rod. When the grip is rotated, the grip causes the support rod to rotate. During the rotation of the support rod, the push plate abuts against the striking block, causing the striking block to separate from the impacted block. The push plate and the striking block work together to continuously strike the impacted block, improving the ease of separation between the striking block and the impacted block.

[0021] Optionally, a roller is rotatably connected to the end of the push plate away from the support rod, and the roller is set horizontally along the length of the push plate.

[0022] By adopting the above technical solution, when the push plate is located directly below the support rod, the roller abuts against the striking block, the push plate pushes the striking block away from the struck block, and the roller rolls along the side of the striking block closer to the struck block, which improves the ease of separating the push plate from the striking block.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the fall arrestor net is placed on the support plate, the cylindrical rod is located inside the cylinder, and the semi-circular block fits into the annular groove to fix the fall arrestor net. When the operator feeds the hopper, the fall arrestor net can reduce the probability of the operator falling into the hopper and improve the safety of feeding the hopper.

[0025] 2. During the separation of the fall arrest net and the support plate, the semicircular block is located in the groove. When the cylindrical rod separates from the cylinder, the first spring pushes the semicircular block to move away from the cylindrical rod, which improves the ease of disassembling the fall arrest net.

[0026] 3. When materials accumulate in the feed hopper, the contact between the striking block and the impacted block vibrates the feed hopper, allowing the materials to fall smoothly into the next processing step, thus improving the convenience of feeding. Attached Figure Description

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] This application discloses a fall-prevention feeding hopper device.

[0036] Example 1

[0037] Reference Figure 1 A fall-prevention feeding hopper device includes a feeding hopper 1, which is vertically arranged. A first baffle 11 is fixedly provided on one side of the upper end of the feeding hopper 1 along the length direction. The first baffle 11 is vertically arranged. Second baffles 12 are fixedly provided on both sides of the upper end of the feeding hopper 1 along the width direction. The second baffles 12 are vertically arranged. The first baffle 11 and the second baffle 12 cooperate to block the upper end of the feeding hopper 1. A cover plate 13 is fixedly provided on the upper end of the second baffle 12 to block the opening between the first baffle 11 and the second baffle 12. A limiting plate 16 is fixedly provided on the side of the second baffle 12 away from the first baffle 11. The limiting plate 16 is located between the two second baffles 12. The lower end of the limiting plate 16 is fixedly connected to the upper end of the feeding hopper 1. The limiting plate 16 is used to block the fall-prevention net plate 2, reducing the probability of the fall-prevention net plate 2 falling from the upper end of the feeding hopper 1 and improving the safety of feeding the feeding hopper 1.

[0038] Reference Figure 2 and Figure 3Multiple support plates 21 are fixedly installed inside the feed hopper 1. A fall arrestor net 2 is installed at the upper end of each support plate 21, supporting the fall arrestor net 2. A cylinder 22, made of elastic material, is fixedly installed vertically at the upper end of each support plate 21. Multiple cylindrical rods 23 are fixedly installed vertically at the lower end of the fall arrestor net 2, located inside the cylinder 22 and slidably connected to the cylinder 22. An annular groove 24 is formed circumferentially on the inner side of the cylinder 22. The lower ends of the cylindrical rods 23 are circumferentially... Multiple semicircular blocks 25 are provided, which are adapted to the annular groove 24. When the cylindrical rod 23 is located inside the cylinder 22, the semicircular blocks 25 are located inside the annular groove 24. When the fall arrest net plate 2 is placed on the support plate 21, the cylindrical rod 23 is located inside the cylinder 22, and the semicircular blocks 25 are in contact with the annular groove 24 to fix the fall arrest net plate 2. When the operator feeds the feed hopper 1, the fall arrest net plate 2 can reduce the probability of the operator falling into the feed hopper 1 and improve the safety of feeding the feed hopper 1.

[0039] Reference Figure 2 and Figure 3 The lower end of the cylindrical rod 23 has multiple first grooves 26 along the circumference. A first spring 27 is provided in the first groove 26. The first spring 27 is horizontally set. The end of the first spring 27 away from the cylindrical rod 23 is fixedly connected to the semicircular block 25. In its natural state, the first spring 27 pushes the semicircular block 25 away from the cylindrical rod 23. During the separation of the fall protection net plate 2 from the support plate 21, the semicircular block 25 is located in the groove. When the cylindrical rod 23 separates from the cylinder 22, the first spring 27 pushes the semicircular block 25 to move away from the cylindrical rod 23, which improves the ease of disassembly of the fall protection net plate 2.

[0040] Reference Figure 1 The second baffle 12 is inclined from bottom to top along the direction from the second baffle 12 towards the first baffle 11 on the side away from the first baffle 11. When the operator is adding material, their body is in an inclined position, and the inclined arrangement of the second baffle 12 helps to improve the convenience of material addition for the operator. Both the upper end of the first baffle 11 and the upper end of the cover plate 13 are connected to an exhaust pipe 14, and an exhaust fan 15 is installed in the exhaust pipe 14. The exhaust fan 15 removes floating objects from the exhaust pipe 14 during the material addition process, which helps to reduce the obstruction of floating objects to the operator and improves the efficiency of material feeding.

[0041] The implementation principle of Embodiment 1 of this application is as follows: the first baffle 11, the second baffle 12 and the cover plate 13 cooperate to block the upper end of the feed hopper 1, the support plate 21 supports the anti-fall net plate 2, and the limiting plate 16 is used to limit the anti-fall net plate 2. When the anti-fall net plate 2 is placed on the support plate 21, the cylindrical rod 23 is located inside the cylinder 22, and the semi-circular block 25 is attached to the annular groove 24 to fix the anti-fall net plate 2. During the separation of the anti-fall net plate 2 from the support plate 21, the semi-circular block 25 is located in the groove. When the cylindrical rod 23 separates from the cylinder 22, the first spring 27 pushes the semi-circular block 25 to move away from the cylindrical rod 23. The anti-fall net plate 2 can reduce the probability of the operator falling into the feed hopper 1 and improve the safety of feeding the feed hopper 1.

[0042] Example 2

[0043] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that impact blocks 3 are fixedly provided on both sides of the feed hopper 1 along its length. The impact blocks 3 are located on the outside of the feed hopper 1. Guide rods 32 are vertically hinged on both sides of the feed hopper 1 along its length. The guide rods 32 are located below the impact blocks 3 and are inclined from bottom to top along the direction from the feed hopper 1 to the impact blocks 3. A striking block 31 is fixedly provided at the upper end of the guide rod 32. The striking block 31 is used to strike the impact blocks 3 to make the feed hopper 1 vibrate. A second spring 33 is provided between the guide rod 32 and the feed hopper 1. In its natural state, the second spring 33 drives the guide rod 32 to move closer to the feed hopper 1, so that the striking block 31 and the impact block 3 are in contact. The upper end of the impact block 3 is provided with a driving device 34, which is used to drive the striking block 31 away from the impact block 3. The second spring 33 drives the guide rod 32 to move closer to the feed hopper 1, thereby causing the striking block 31 to come into contact with the impact block 3. When the material accumulates in the feed hopper 1, the contact between the striking block 31 and the impact block 3 causes the feed hopper 1 to vibrate, so that the material falls smoothly to the next processing step, improving the convenience of feeding.

[0044] Reference Figure 4 and Figure 5The driving device 34 includes two fixed blocks 341, a support rod 342, and a grip rod 343. The two fixed blocks 341 are respectively fixedly connected to both sides of the upper end of the impact block 3 along the length direction. Both fixed blocks 341 are vertically arranged. The support rod 342 is located between the two fixed blocks 341 and is rotatably connected to the fixed blocks 341. The grip rod 343 passes through the fixed blocks 341 and is fixedly connected to one end of the support rod 342 along the length direction. When the grip rod 343 rotates, it drives the support rod 342 to rotate together. The grip 343 is rotatably connected to the fixed block 341. The support rod 342 is fixed with multiple push plates 345 along the circumference. When the push plate 345 is directly below the support rod 342, the end of the push plate 345 away from the support rod 342 abuts against the striking block 31. During the rotation of the support rod 342, the push plate 345 abuts against the striking block 31, causing the striking block 31 to separate from the impacted block 3. The push plate 345 and the striking block 31 work together to continuously strike the impacted block 3, improving the ease of separation between the striking block 31 and the impacted block 3.

[0045] Reference Figure 5 and Figure 6 A roller 344 is rotatably connected to one end of the push plate 345 away from the support rod 342. The roller 344 is horizontally set along the length of the push plate 345. The push plate 345 pushes the striking block 31 away from the striking block 3. The roller 344 rolls along the side of the striking block 31 close to the striking block 3, which improves the ease of separation between the push plate 345 and the striking block 31.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
