Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a feeding device for a bucket elevator. Background Technology

[0002] Bucket elevators are widely used in many industries for the vertical transport of materials. However, existing bucket elevator feeding devices have some problems in actual use; for example, material is prone to clogging during feeding, the feeding speed is difficult to control precisely, and the material distribution is uneven. Therefore, a dedicated feeding device needs to be installed at the feed inlet.

[0003] In the prior art, utility model patent with patent number CN202322168106.X discloses a feeding device for a bucket elevator, including a bucket elevator body, a mounting base fixedly connected to the bottom of the bucket elevator body, a feeding pipe fixedly connected to one side of the bucket elevator body, a feeding hopper fixedly connected to one end of the feeding pipe, a cover fixedly connected to the front side of the feeding hopper, a uniform feeding component arranged between the cover and the feeding hopper, and a feeding flow rate control component arranged between the bucket elevator body and the feeding pipe. The uniform feeding component includes a rotating shaft fixedly connected to the inner walls of the front and rear sides of the feeding hopper and a drive motor fixedly connected to the front side of the feeding hopper.

[0004] The aforementioned patent provides a feeding device for a bucket elevator. This device can feed materials evenly and smoothly, and can control the feeding speed to avoid jamming caused by too much material entering at once. However, although the device can improve feeding efficiency by setting a rotating drum with paddles in the feeding hopper, when too much material is added, the material will accumulate and fill the gaps around the rotating drum, making it difficult for the drum to rotate. At the same time, when the paddles push the material to convey it, they will squeeze the material, which not only fails to crush the already clumped parts of the material, but may also squeeze the dispersed material to clump again. Further improvements are needed. Utility Model Content
