Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a belt conveyor with a material guiding mechanism. Background Technology

[0002] A belt conveyor is a mechanical device that uses a continuously moving conveyor belt to transport materials. It achieves continuous, efficient, and long-distance material transport through the friction or traction between the belt and the material. It is widely used in various industries such as mining, metallurgy, chemicals, logistics, and food processing.

[0003] A belt conveyor with a guiding mechanism is a device that adds a guiding mechanism to a regular belt conveyor. The core function of this mechanism is to guide materials accurately, evenly, and stably into the conveyor belt, preventing material spillage, deviation, or impact on the belt, thereby improving conveying efficiency, protecting the equipment, and reducing material loss. Common guiding mechanisms include guide hoppers, which are usually installed above the feed end of the conveyor belt; and guide plates, which are inclined or curved metal plates installed below the feed inlet.

[0004] The size of the lower opening of existing feed hoppers is generally fixed, which presents significant limitations when conveying materials of different particle sizes: When conveying fine-grained materials, if the outlet is too wide, the material may disperse too quickly due to gravity, leading to spillage, uneven accumulation, or even deviation from the belt conveyor. A narrower outlet can concentrate the material flow, ensuring it lands stably in the center of the belt. When conveying coarse-grained materials, if the outlet is too narrow, the material size may exceed the outlet width and cause jamming. Therefore, a wider outlet is needed to ensure smooth material passage and avoid blockages. This makes existing feed hoppers unsuitable for guiding materials of different particle sizes. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing feed hoppers in which it is inconvenient to guide materials of different particle sizes, and to propose a belt conveyor with a feed guiding mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a belt conveyor with a material guiding mechanism, including a support frame. Two rotating rollers are rotatably connected to both ends of the support frame via bearings. A transmission belt is provided between the two rotating rollers. One of the rotating rollers is driven by a motor. A fixed frame is fixedly connected to the support frame. A material guiding frame is fixedly connected to the upper end of the fixed frame. A feed hopper is fixedly connected to the upper end of the material guiding frame. Notches are provided on both sides of the material guiding frame. A rotating shaft is rotatably connected to each of the two notches via sealed bearings. A baffle is fixedly connected to each of the two rotating shafts. The two rotating shafts are adjusted by an adjustment mechanism.

[0008] Preferably, both baffles are made of wear-resistant steel.

[0009] Preferably, the adjusting mechanism includes a gear that meshes with a rack, and the rack is moved by a moving mechanism.

[0010] Preferably, the moving mechanism includes a fixed part, which is fixedly connected to the outer wall of the guide frame. A bidirectional threaded rod is rotatably connected to the fixed part via a bearing. Both ends of the bidirectional threaded rod are threaded through and connected to connecting ears. The two connecting ears are respectively fixedly connected to a rack and pinion, and the connecting ears are limited by a limiting mechanism.

[0011] Preferably, the limiting mechanism includes a positioning rod that passes through the connecting ear and is fixedly connected to the fixing part.

[0012] Preferably, a clamping block is fixedly connected to one end of the bidirectional threaded rod.

[0013] Preferably, a protective frame is fixedly connected to the outer wall of the guide frame, a connecting plate is fixedly connected to the protective frame, and the bidirectional threaded rod is rotatably connected to the guide frame through a bearing.

[0014] Preferably, the bidirectional threaded rod is made of high-strength chromium-molybdenum steel.

[0015] The present invention proposes a belt conveyor with a material guiding mechanism, which has the following advantages: by adjusting the mechanism to drive the two baffles to rotate, the distance between the lower ends of the two baffles is changed, thereby changing the size of the discharge port to adapt to the material guiding requirements of different particle sizes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figure 1-4 and Figure 6 A belt conveyor with a material guiding mechanism includes a support frame 2. Two rotating rollers 10 are rotatably connected to both ends of the support frame 2 via bearings. A transmission belt 1 is provided between the two rotating rollers 10. One of the rotating rollers 10 is driven by a motor 4, which is mounted on the support frame 2. A fixed frame 6 is fixedly connected to the support frame 2. A material guiding frame 7 is fixedly connected to the upper end of the fixed frame 6. A feed hopper 3 is fixedly connected to the upper end of the material guiding frame 7. Notches 8 are provided on both sides of the material guiding frame 7. A rotating shaft 13 is rotatably connected to each of the two notches 8 via sealed bearings. Baffles 9 are fixedly connected to each of the two rotating shafts 13. The two rotating shafts 13 are adjusted by an adjustment mechanism. The adjustment mechanism drives the two baffles 9 to rotate, changing the distance between the lower ends of the two baffles 9, thereby changing the size of the discharge port to adapt to the material guiding requirements of different particle sizes.

[0025] Both baffles 9 are made of wear-resistant steel. When guiding materials, the baffles 9 come into contact with the materials. Using wear-resistant steel helps to improve the wear resistance of the baffles 9.

[0026] Example 2: Refer to Figure 1-5 In another preferred embodiment of this utility model, based on embodiment 1, the adjusting mechanism includes a gear 18, which meshes with a rack 12, and the rack 12 moves via a moving mechanism. The moving mechanism includes a fixing part 14, which is fixedly connected to the outer wall of the guide frame 7. A bidirectional threaded rod 15 is rotatably connected to the fixing part 14 via a bearing. The bidirectional threaded rod 15 is made of high-strength chromium-molybdenum steel and can withstand heavy loads.

[0027] Both ends of the bidirectional threaded rod 15 are threaded through and connected to connecting lugs 16. The two connecting lugs 16 are fixedly connected to racks 12, and are limited by a limiting mechanism. When the bidirectional threaded rod 15 rotates, it drives the two racks 12 to move in opposite directions, thereby driving the two meshing gears 18 to rotate simultaneously, which in turn drives the two baffles 9 to rotate synchronously. This eliminates the need for individual adjustment of each baffle 9, improving operational convenience.

[0028] Example 3: Reference Figure 5 As another preferred embodiment of this utility model, based on embodiment 2, the limiting mechanism includes a positioning rod 17, which passes through the connecting ear 16 and is fixedly connected to the fixing part 14. When the bidirectional threaded rod 15 is rotated, the positioning rod 17 plays a limiting role, preventing the rack 12 from rotating.

[0029] A clamping block 19 is fixedly connected to one end of the bidirectional threaded rod 15. The clamping block 19 is provided so that it can be clamped with a wrench, thereby driving the bidirectional threaded rod 15 to rotate, making the operation more convenient.

[0030] When adjusting the size of the discharge port at the lower end of the guide frame 7, clamp the clamping block 19 with a wrench and rotate it. This, in turn, rotates the bidirectional threaded rod 15, driving the two racks 12 to move. The racks 12 drive the gears 18 to rotate, the gears 18 drive the rotating shaft 13 to rotate, and the rotating shaft 13 then drives the baffle 9 to rotate, thereby adjusting the distance between the lower ends of the two baffles 9. After adjustment, the material is discharged from the feed hopper 3 and falls onto the transmission belt 1 through the discharge port of the guide frame 7 for conveying.

[0031] Example 4: In Example 3, because gear 18 and rack 12 are exposed, dust can easily enter them, affecting the transmission of gear 18 and rack 12. (Refer to...) Figure 1-5 As another preferred embodiment of this utility model, based on embodiment 3, a protective frame 11 is fixedly connected to the outer wall of the guide frame 7, and a connecting plate 5 is fixedly connected to the protective frame 11. The bidirectional threaded rod 15 is rotatably connected to the guide frame 7 through a bearing. By using the protective frame 11 and the connecting plate 5, a sealing effect is achieved, preventing the gear 18 and the rack 12 from being exposed, and avoiding dust and powder particles from entering between the gear 18 and the rack 12.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
