Description

Technical Field

[0001] This application relates to the field of materials, and in particular to an anti-clogging structure for the feed inlet of a hoist. Background Technology

[0002] In modern industrial production, elevators, as an important vertical material conveying device, are widely used in many industries such as mining, chemical, food, and building materials. They can efficiently lift materials from low to high places, providing a stable material supply for subsequent production and processing stages, and playing a key connecting role in the entire production process.

[0003] However, when existing elevators are unloading material at the bottom, due to various factors such as the material's flow rate, velocity, and characteristics, a large amount of material often accumulates at the bottom feed inlet. This accumulation reduces the effective flow area of ​​the feed inlet, slows down the material's entry into the elevator, and consequently reduces the overall conveying efficiency and affects the overall conveying progress of the elevator.

[0004] Regarding the aforementioned technologies, the inventors believe that the elevator suffers from material accumulation and blockage at the feed inlet during use. Therefore, they have proposed an anti-blockage structure for the feed inlet of the elevator to solve the above problems. Utility Model Content

[0005] In order to solve the problem of material accumulation and blockage at the feed inlet of the elevator during use, this application provides an anti-blockage structure for the feed inlet of the elevator.

[0006] The anti-blocking structure at the feed port of a hoist provided in this application adopts the following technical solution:

[0007] A clog prevention structure for the feed inlet of a hoist includes a hoist body, a conveyor belt movably installed inside the hoist body, several baffles fixed to the outer surface of the conveyor belt, a feeding frame at the bottom of the hoist body, a discharge mechanism at the bottom of the feeding frame, a support shaft symmetrically and rotatably installed at the top of the feeding frame, a guide frame fixed to the outer surface of the support shaft, several placement grooves on the outer surface of the guide frame, a first pulley extending from one side of the support shaft to the outside of the feeding frame, a second pulley symmetrically and rotatably installed between the two first pulleys at the middle of one side of the feeding frame, a connecting belt sleeved on the outer surface of the first and second pulleys, a gear fixed to the middle of one side of the second pulley, and a drive motor installed on the other side of the support shaft extending to the outer surface of the feeding frame.

[0008] Preferably, the unloading mechanism includes an unloading hopper, which is fixedly installed at the top center of the feeding frame. Movable baffles are rotatably installed on both sides of the bottom of the inner wall of the unloading hopper, and limit screws are threadedly connected to the bottom of both sides of the unloading hopper near the lower part of the movable baffles.

[0009] Preferably, a groove is provided in the middle of one side of the outer surface of both the first and second pulleys, and the connecting belt is located in the groove inside the first and second pulleys, with both the first and second pulleys engaging with the connecting belt.

[0010] Preferably, the two gears are the same size and structure, and the two gears are close to each other and mesh.

[0011] Preferably, a through hole is provided in the middle of the bottom end of the unloading hopper, and the width of the front and rear ends of the movable baffle is smaller than the width of the front and rear ends of the inner wall at the opening of the through hole, and the movable baffle and the through hole are fitted together.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The drive motor drives the support shaft to rotate. The transmission structure consisting of the first pulley, the second pulley, and the connecting belt, as well as the meshing gears, ensures the stability and reliability of power transmission, ensuring that the guide frame can operate continuously and stably. This allows the guide frame to rotate, and the placement groove on the guide frame can guide and disperse the material in an orderly manner, preventing the material from accumulating at the feed point and effectively improving the smoothness of feeding.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses an anti-blocking structure at the feed inlet of a hoist. (Refer to...) Figure 1-4 A clog prevention structure at the feed inlet of a hoist includes a hoist body 1, a conveyor belt 2 movably installed inside the hoist body 1, several baffles 3 fixedly connected to the outer surface of the conveyor belt 2, a feeding frame 4 at the bottom of the hoist body 1, a discharge mechanism at the bottom of the feeding frame 4, a support shaft 5 symmetrically and rotatably installed at the top of the feeding frame 4, a guide frame 6 fixedly connected to the outer surface of the support shaft 5, several placement grooves 7 formed on the outer surface of the guide frame 6, a first pulley 8 extending from one side of the support shaft 5 to the outside of the feeding frame 4, and a symmetrically and rotatably installed between two first pulleys 8 on one side of the feeding frame 4. There is a second pulley 9, and a connecting belt 10 is fitted on the outer surface of the first pulley 8 and the second pulley 9. A groove is opened in the middle of one side of the outer surface of the first pulley 8 and the second pulley 9. The connecting belt 10 is located in the groove inside the first pulley 8 and the second pulley 9. The first pulley 8 and the second pulley 9 are both fitted with the connecting belt 10. A gear 11 is fixed in the middle of one side of the second pulley 9. The two gears 11 are the same in size and structure, and the two gears 11 are close to each other and mesh. A drive motor 12 is installed on the other side of a single support shaft 5 extending to the outer surface of the feeding frame 4.

[0022] The drive motor 12 starts, and its output shaft drives the support shaft 5 to rotate. The first pulley 8 rotates with the support shaft 5, and drives the second pulley 9 to rotate through the connecting belt 10. The meshing gears 11 ensure the synchronous rotation between the two second pulleys 9, thus ensuring the stable and continuous operation of the two support shafts 5. The rotation of the support shaft 5 causes the guide frame 6, which is fixed to its outer surface, to rotate as well, allowing the material to enter from the top of the feeding rack 4 and fall into the placement groove 7 on the outer surface of the guide frame 6. As the guide frame 6 continues to rotate...

[0023] Reference Figure 3 and Figure 4The unloading mechanism includes an unloading hopper 13, which is fixedly installed at the top center of the feeding frame 4. Movable baffles 14 are rotatably installed on both sides of the bottom of the inner wall of the unloading hopper 13. Limiting screws 15 are threadedly connected to the bottom of both sides of the unloading hopper 13 near the lower part of the movable baffles 14. A through hole is opened through the middle of the bottom end of the unloading hopper 13. The width of the front and rear ends of the movable baffles 14 is smaller than the width of the front and rear ends of the inner wall at the opening of the through hole. The movable baffles 14 and the through hole are fitted together.

[0024] The discharge hopper 13 is used to store materials to be fed into the main body 1 of the elevator. The angle of the movable baffle 14 can be adjusted by rotating the limiting screw 15. When it is necessary to speed up the discharge or increase the discharge volume, the movable baffle 14 can be rotated to a suitable angle so that the material can flow out from the through hole at the bottom of the discharge hopper 13 faster and in greater quantities.

[0025] The implementation principle of the anti-blocking structure at the feed inlet of the elevator according to an embodiment of this application is as follows: When the elevator starts working, the drive motor 12 starts, and its output shaft drives the support shaft 5 to rotate. The rotation of the support shaft 5 causes the guide frame 6 fixed to its outer surface to rotate accordingly, allowing the material to enter from the top of the feeding frame 4 and fall into the placement groove 7 on the outer surface of the guide frame 6. As the guide frame 6 continues to rotate, the material in the placement groove 7 is gradually guided to the feed inlet of the elevator body 1. Due to the dispersing effect of the rotation of the guide frame 6, the material will not accumulate at the feed inlet, thus ensuring the smoothness of the feed.

[0026] Meanwhile, the unloading mechanism also functions. The unloading hopper 13 stores the material to be fed into the elevator body 1. The angle of the movable baffle 14 can be adjusted by rotating the limiting screw 15. When it is necessary to speed up the unloading speed or increase the unloading volume, the movable baffle 14 can be rotated to a suitable angle, allowing the material to flow out faster and in greater quantities from the through-hole at the bottom of the unloading hopper 13. Conversely, when it is necessary to slow down the unloading speed or reduce the unloading volume, the movable baffle 14 can be adjusted to restrict the outflow of material. This flexible unloading control method can further prevent material blockage at the feed point according to different material characteristics and flow requirements.

[0027] In terms of power transmission, the first pulley 8 rotates with the support shaft 5, and drives the second pulley 9 to rotate through the connecting belt 10. The meshing gears 11 ensure the synchronous rotation between the two second pulleys 9, thereby ensuring that the entire guide frame 6 can operate stably and continuously, providing reliable power support and material guidance for the feeding process of the elevator.
