Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically a bucket elevator scraper conveyor. Background Technology

[0002] In the field of material handling, scraper conveyors, as a common continuous conveying equipment, are widely used for the horizontal or inclined transport of bulk materials such as coal, ore, and grain. However, traditional scraper conveyors have the following technical defects in the material feeding stage:

[0003] In existing technologies, materials are typically fed onto scraper conveyors manually or using simple equipment (such as chutes). Manual operation is labor-intensive and inefficient, making it difficult to meet the demands of large-scale continuous production. Specifically, existing technologies lack a device that efficiently integrates the elevator and scraper conveyor and allows for flexible adjustment of the feeding angle. This results in low material conveying efficiency, insufficient automation, and an inability to meet the demands of industrial production for high efficiency and flexibility. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This utility model provides a bucket elevator scraper conveyor device, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bucket elevator scraper conveyor, comprising a scraper conveyor with a frame on its outer side, and an elevator installed at one end of the frame, which is used to feed materials onto the scraper conveyor. The elevator includes a U-shaped base, a drive source support, a linear drive source, and a hopper support assembly. The side of the U-shaped base facing the frame is fixedly connected to the frame. The top of the U-shaped base has deflection support portions on opposite sides, which are rotatably connected to the hopper support assembly. The drive source support is fixed to the bottom of the U-shaped base using fasteners. The lower end of the linear drive source is rotatably connected to the drive source support. The output end of the linear drive source is rotatably connected to the hopper support assembly. The extension and retraction of the output end of the linear drive source allows the hopper support assembly to deflect with the deflection support portions as support.

[0008] Preferably, the hopper support assembly includes a reinforcing support beam, two side frames, and a base. The two ends of the reinforcing support beam are fixedly connected to the tops of the two side frames, respectively. A drive connection part is formed in the middle of the reinforcing support beam and is rotatably connected to the output end of a linear drive source. The tops of the two side frames are each formed with a deflection connection part and are rotatably connected to an adjacent deflection support part. The bottoms of the two side frames are fixedly connected to the base by fasteners. A material inlet is formed on the side of the base facing away from the scraper conveyor. The hopper can be placed between the reinforcing support beam, the two side frames, and the base through the material inlet. A fixing hole is formed on the side of the base that penetrates the base and is connected to the side frames.

[0009] In a further preferred embodiment, the hopper support assembly further includes a tilting support frame disposed between the two side frames. The tilting support frame is fixedly connected to the upper sections of the two side frames respectively, and is used to support the hopper during tilting. The tilting support frame includes a support plate and two limiting plates. The two limiting plates are respectively formed on opposite sides of the support plate, and are fixedly connected to adjacent side frames.

[0010] (III) Beneficial Effects

[0011] Compared with the prior art, this utility model provides a bucket elevator scraper conveyor device, which has the following beneficial effects:

[0012] In this invention, the telescopic movement of the linear drive source drives the material box support assembly to deflect around the deflection support as the axis, thereby enabling the material to be fed into the scraper conveyor. This can reduce the need for manual labor and allow for automatic material feeding. In addition, the deflection angle of the material box support assembly can be adjusted according to the material characteristics such as particle size and moisture content to optimize the feeding angle and make the device more flexible in feeding materials.

[0017] 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.

[0018] Please see Figure 1 A bucket elevator scraper conveyor includes a scraper conveyor 10 and an elevator 20. A frame 11 is provided on the outside of the scraper conveyor 10, and the elevator 20 is installed at one end of the frame 11 and is used to feed materials onto the scraper conveyor 10.

[0019] See Figure 2 and Figure 3 The elevator 20 includes a U-shaped base frame 21, a drive source support 22, a linear drive source 23, and a hopper support assembly. The U-shaped base frame 21 is fixedly connected to the frame 11 on one side facing it. Deflection support portions 211 are formed on opposite sides of the top of the U-shaped base frame 21 and are rotatably connected to the hopper support assembly. The drive source support 22 is fixed to the bottom of the U-shaped base frame 21 using fasteners. The lower end of the linear drive source 23 is rotatably connected to the drive source support 22, and the output end of the linear drive source 23 is rotatably connected to the hopper support assembly. The linear drive source 23 can be a hydraulic or pneumatic actuator, and its output end can be driven to produce linear movement along the extension and retraction of its cylinder. By extending or retracting the output end of the linear drive source 23, the hopper support assembly can be deflected using the deflection support 211 as a support. This allows the hopper, after being pre-placed within the hopper support assembly, to be deflected upwards, and material can be fed onto the scraper conveyor 10 after the hopper tilts towards it. Furthermore, the deflection angle of the hopper support assembly can be adjusted by changing the extension length of the output end of the linear drive source 23.

[0020] In this embodiment, the hopper support assembly may include a reinforcing support beam 24, two side frames 25, a base 26, and a tilting support frame 27. The two ends of the reinforcing support beam 24 are fixedly connected to the tops of the two side frames 25, respectively. The bottoms of the two side frames 25 are fixedly connected to the base 26 using bolts or other fasteners. The tilting support frame 27 is fixedly connected to the upper sections of the two side frames 25. A material inlet 262 is formed on the side of the base 26 facing away from the scraper conveyor 10, allowing the hopper to be placed between the reinforcing support beam 24, the two side frames 25, and the base 26 through the material inlet 262, and the tilting support frame 27 can support the hopper during tilting. A drive connection portion 241 is formed in the middle of the reinforcing support beam 24, rotatably connected to the output end of the linear drive source 23. A deflection connection portion 251 is formed at the top of each of the two side frames 25, rotatably connected to the adjacent deflection support portion 211.

[0021] In this embodiment, a fixing hole 261 is formed on the side of the base 26, which penetrates the base 26 and is connected to the side frame 25, so that the fastener can pass through the fixing hole 261 and be connected to the side frame 25.

[0022] In this embodiment, the tilting support frame 27 includes a support plate 271 and two limiting plates 272. The two limiting plates 272 are respectively formed on opposite sides of the support plate 271, and are fixedly connected to adjacent side frames 25. The tops of both the support plate 271 and the limiting plates 272 extend above the side frames 25, and the distance between the top of the support plate 271 and the bottom support 26 is adapted to the height of the material box, so that the support plate 271 can provide support from the bottom when the material box tilts and tilts to pour materials. The distance between the two limiting plates 272 is adapted to the relative width of the material box. After the material box is placed within the space enclosed by the reinforcing support beam 24, the two side frames 25, and the bottom support 26, the two limiting plates 272 can be used to clamp and secure the material box. Additionally, an anti-slip pad can be adhered to the opposite sides of the two limiting plates 272 to make the placement of the material box more stable and reduce slippage when the material box is tilted.

[0023] The system of the present invention may further include a control system for controlling the extension and retraction of the output end of the linear drive source to automatically operate the hopper support assembly and the hopper deflection for material feeding. It should be understood that this control system is not particularly limited and can be implemented using existing control techniques, which will not be elaborated upon here.
