Description

Technical Field

[0001] This invention relates to the field of feed breaker technology, and more specifically to an arch-breaking device with a slewing bearing. Background Technology

[0002] In modern industrial production, the storage and transportation of various bulk materials are frequently encountered. Due to the adhesion and friction on the inner walls of storage silos or conveying pipelines, materials are prone to "arching," preventing normal material discharge or transportation and thus affecting production. Therefore, to ensure smooth material discharge and transportation, various arch-breaking devices are often used. These devices typically use external power to drive their internal structure, thereby altering the internal material's mechanical state to break the material pile structure and eliminate the "arching" phenomenon. Common arch-breaking devices include rotary arch breakers, pneumatic hammer arch breakers, and vibratory motor arch breakers. However, currently, rotary valve arch breakers come in various structures, most of which are complex, allowing material dust to easily enter and preventing proper sealing.

[0022] Example 1

[0023] like Figures 1-4 As shown, this embodiment 1 designs an arch-breaking device with a slewing bearing, which includes the following specific structural configuration: The hopper 1 is configured as a funnel-shaped structure and is also equipped with a connecting flange 11; The main body 2 of the arch-breaking device includes a main shell 20, a slewing bearing 21, a rotating ring 22, a connecting pipe 23, a scraper 24, a sealing ring 25, a drive shaft 26, a drive gear 27, a driven shaft 28, and a driven gear 29. The main shell 20 includes a base 201 and a top cover 202. The top cover 204 is detachably connected to the base 201 by bolts and forms an installation cavity 203 inside. The main shell 20 also has a through hole 204 penetrating the base 201 and the top cover 202. The 01 and the top cover 202 are respectively provided with a first limiting ring 205 and a second limiting ring 206 coaxial with the through hole 204. The connecting pipe 23 is coaxially disposed in the through hole 204. The slewing bearing 21 is disposed in the mounting cavity 203. The inner ring 211 of the slewing bearing 21 is detachably connected to the base 201 by bolts, and the inner ring 211 is also coaxial with the connecting pipe 23. The first limiting ring 205 is located between the connecting pipe 23 and the inner ring 211. The rotating ring 22 and the... The slewing bearing 21 is coaxially mounted and detachably bolted to the outer ring 212 of the slewing bearing 21, driving its rotation. The connecting pipe 23 is also connected to the rotating ring 22, driving it to rotate synchronously. The hopper 1 is detachably connected to the upper cover 202 via the connecting flange 11, and the hopper 1 communicates with the connecting pipe 23. One end of the scraper 24 is connected to the inner wall of the connecting pipe 23, and the other end extends into the hopper 1 and is close to the inner wall. The sealing rings 25 are respectively disposed on the... Between the outer wall of the connecting pipe 23 and the first limiting ring 205 and the second limiting ring 206, the drive shaft 26 is rotatably mounted on the base 201 and the upper cover 202, the drive gear 27 is mounted on the drive shaft 26, the driven shaft 28 is mounted on the base 201 and the upper cover 202, a bearing 30 is sleeved on the driven shaft 28, and the driven gear 29 is connected to the outer ring of the bearing 30. The driven gear 29 meshes with the drive gear 27 and the outer ring 212 of the slewing bearing 21. And a drive device (gear motor) 3, which is connected to the upper cover 202, is used to directly drive the drive shaft 26 to rotate, thereby driving the scraper 24 to rotate, so as to scrape off the material arched on the inner wall of the silo 1 and break it up.

[0024] Specifically, the working process of the arch-breaking device with a slewing bearing in Embodiment 1 is as follows: the drive device (reduction motor) 3 directly drives the drive shaft 26 to rotate, which in turn drives the drive gear 27 to rotate. The drive gear 27 then drives the driven gear 29 to rotate. The driven gear 29 then drives the outer ring 212 of the slewing bearing 21 to rotate. The outer ring 212 continues to drive the rotating ring 22 to rotate synchronously. The rotating ring 22 then drives the connecting pipe 23 to rotate in the through hole 204. The connecting pipe 23 then drives the scraper 24 to rotate synchronously. After the scraper 24 rotates, it can scrape off the arched material on the inner wall of the silo 1, thereby breaking the arch.

[0025] The arch-breaking device with a slewing bearing designed in Embodiment 1 above has a high degree of structural integration and compact axial dimensions: the structural design of driving the connecting pipe 23 to rotate synchronously through the rotating ring 22 eliminates the need for a long drive shaft; combined with the slewing bearing inner ring 211 being directly fixed to the base 201, a compact modular structure can be formed, significantly reducing the axial dimensions of the arch-breaking device, making it more suitable for space-constrained applications and improving its applicability; at the same time, the arch-breaking device is also designed with a two-stage gear transmission mechanism (i.e., driving gear 27 → driven gear 29 → slewing bearing outer gear ring 212), which can easily adjust the transmission ratio by replacing the driven gear 29, thereby adjusting the rotational speed and torque of the scraper 24 to adapt to different materials fed on the inner wall of the silo 1 for arch-breaking operations.

[0026] The above-described preferred embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of the invention. Any obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
