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.

[0015] Please see Figures 1-5 This utility model provides a technical solution: A bucket elevator with a feeding noise reduction mechanism includes a bucket elevator 1, characterized in that: a feeding noise reduction mechanism 2 is provided below the bucket elevator 1 for feeding noise reduction, and the feeding noise reduction mechanism 2 includes: The noise reduction unit 21 is located below the bucket elevator 1 and includes a feed box 211 fixedly installed inside the base frame of the bucket elevator 1. A first baffle 215 is rotatably installed on the front side inside the feed box 211, and a second baffle 216 is rotatably installed on the rear side inside the feed box 211. The first baffle 215 and the second baffle 216 are elastically supported by the support unit 22 to block the falling material and reduce its falling momentum. The support unit 22 is disposed inside the noise reduction unit 21 and is used to provide elastic support for the rubber pad 217 and the second baffle 216. The support unit 22 includes a large arm 221 and a small arm 222. The small arm 222 is slidably installed inside the large arm 221, and a spring 225 is installed inside the large arm 221. Both the large arm 221 and the small arm 222 are provided with connecting components 3 at their outer ends. The connecting components 3 support the first baffle 215 and the second baffle 216. A limit block 223 is fixedly installed inside the large arm 221 by bolts. A limit groove 224 is opened on the surface of the small arm 222, and the limit block 223 slides inside the limit groove 224 to limit the movement of the small arm 222. The support unit 22 consists of a large arm 221, a small arm 222, a spring 225, a limiting block 223, and a limiting groove 224. It supports the baffle through the connecting component 3, and the spring 225 absorbs the impact force through the extension and retraction of the large and small arms to achieve flexible blocking.

[0016] The connecting assembly 3 includes multiple sets of hinge seats 36 that are fixedly installed on the bottom of the rubber pad 217, the second baffle 216, and the inside of the feed box 211. A socket 33 is fixedly installed on one end of the hinge seat 36. A threaded sleeve 35 is movably installed on the surface of the socket 33. A cross-shaped insertion hole 34 is opened inside the socket 33. A fixing seat 31 is fixedly installed on the outer end of the upper arm 221 and the lower arm 222. A cross-shaped insertion block 32 is fixedly installed on one end of the fixing seat 31. The cross-shaped insertion block 32 slides into the inside of the cross-shaped insertion hole 34. The threaded sleeve 35 is screwed and rotated on the surface of the fixing seat 31.

[0017] The connecting component 3 uses a cross-shaped insert 32 and a cross-shaped socket 34 for insertion and mating, supplemented by a threaded sleeve 35 for locking. During disassembly, the support unit 22 can be separated simply by loosening the threaded sleeve, making it easy to replace the spring 225 or the rubber pad 217.

[0018] In this embodiment, rubber pads 217 are fixedly installed on the top of both the first baffle 215 and the second baffle 216. The noise of the material falling is reduced by the material falling above the rubber pads 217.

[0019] When the material falls, it impacts the first baffle 215 and the second baffle 216. The spring 225 in the support unit 22 absorbs the impact force through the extension and retraction of the upper arm 221 and the lower arm 222, which significantly reduces the kinetic energy and momentum of the falling material.

[0020] The rubber pad 217 acts as a buffer medium, directly reducing the noise from the hard collision between the material and the baffle.

[0021] In this embodiment, an inclined plate 218 is fixedly installed inside the feed box 211, and the material is concentrated by the inclined surface of the inclined plate 218.

[0022] The inclined design guides the material to fall into the elevator hopper in a concentrated manner, avoiding scattering and impacting the side wall of the box.

[0023] In this embodiment, a cabinet door 212 is hinged to the right side of the feed box 211, a locking post 214 is fixedly installed on the outside of the cabinet door 212, and a locking block 213 is rotatably installed on the right side of the feed box 211, and the locking block 213 is rotatably locked onto the surface of the locking post 214.

[0024] The cabinet door 212 is installed on the right side of the feed box 211 by means of the rotating engagement of the locking block 213 and the locking post 214. The cabinet door 212 can be opened quickly without tools, which is convenient for cleaning the inside of the feed box or inspecting the parts.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] During operation, the material is first poured into the inside of the feed box 211 from the top opening. The material falls onto the rubber pad 217. When there is too much material, the first baffle 215 rotates in an arc shape, squeezing the small arm 222 through the connecting component 3. The small arm 222 squeezes the spring 225, and the material falls from the opening of the first baffle 215 into the upper part of the second baffle 216. The second baffle 216 operates in the same way, and the material falls onto the inclined plate 218. The material is then lifted by the bucket elevator 1. Then, the operator rotates the threaded sleeve 35 to disengage it from the fixed seat 31, pulls the cross-shaped insert 32 out of the cross-shaped insert hole 34, disassembles and repairs the forearm 222 and the boom 221, the operator rotates the locking block 213 to disengage it from the locking post 214, and opens the cabinet door 212 to inspect the inside of the feed box 211.
