Abstract
Description
Technical Field
[0001] This disclosure relates to the field of coal conveying equipment technology, and more specifically, to a slag chute device. Background Technology
[0002] As a common conveying device in coal production and use, the slag chute plays a crucial role in safely and efficiently guiding coal or other solid particles from a high position to a low position, ensuring that the material slides smoothly along a preset path for subsequent transportation or loading operations. This function relies primarily on the downward tilting action of the slag chute during operation. Specifically, in operation, the slag chute tilts downward to a specific angle as needed. This angle is carefully designed to ensure that materials such as slag slide smoothly to the designated collection area. In this way, the slag chute not only guides the material but also prevents coal from falling directly onto equipment or the work area, reducing damage to the equipment and contamination of the work area. Conversely, in non-operational mode, the slag chute tilts upward and retracts. This design aims to prevent the slag chute from protruding outward, thus preventing collisions with other objects or creating safety hazards. This flexible tilting design allows the slag chute device to adapt to different operational needs.
[0003] Although slag chutes play a vital role in coal production, their transmission components are prone to failure due to prolonged operation in high-dust environments, resulting in low reliability. High-dust environments not only corrode and wear transmission parts but also affect the normal operation of the lubrication system, increasing friction between components and further exacerbating malfunctions. Utility Model Content
[0004] The purpose of this disclosure is to provide a slag chute device to at least partially solve the problems existing in the related art.

[0010] Gear set, which drives the drive motor and the slag chute body; and
[0011] A gear guard is connected to the mounting base, and the interior of the gear guard has a receiving cavity for accommodating the gear set.
[0012] Optionally, the gear set includes a first gear, a second gear, and a rotary drive shaft. The output shaft of the drive motor is coaxially connected to the first gear.

[0031] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0032] In this disclosure, unless otherwise stated, the directional terms "upper," "lower," "top," and "bottom" are defined based on the actual direction of use of the relevant components. "Inner" and "outer" refer to the outline of the corresponding parts themselves. The terms "first," "second," etc., are used to distinguish different components and do not indicate sequence or importance. In this disclosure, when the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0033] Reference Figures 1 to 5 This disclosure provides a slag chute device, which may include a slag chute body 1, at least one mounting base 2, and a drive assembly 3. The mounting base 2 is installed on the side of the slag chute body 1. In embodiments of this disclosure, mounting bases 2 are provided on both sides of the slag chute body 1, and the slag chute body 1 is located between the two mounting bases 2, forming a stable support structure. The slag chute body 1 is rotatably connected to the mounting base 2. The drive assembly 3 is used to drive the slag chute body 1 to rotate, thereby performing a flipping action. The drive assembly 3 may include a drive motor 31, a gear set, and a gear protective cover 33. The drive motor 31 is mounted on the mounting base 2. The gear set drives the drive motor 31 and the slag chute body 1. The gear protective cover 33 is connected to the mounting base 2; specifically, the two can be fixed by bolts. The interior of the gear protective cover 33 has a receiving cavity for accommodating the gear set.
[0034] Through the above technical solution, the combination of the drive motor and gear set provides a stable power source for the chute plate body. Driven by the drive assembly, the chute plate body can perform a flipping motion around the fulcrum of the mounting base, allowing the chute plate body to flexibly adjust its angle and position to adapt to different operating conditions. The gear set is located inside the receiving cavity of the gear protective cover, which can effectively block dust from entering the shaft system and damaging the gears, reducing the failure rate of shafts, gears, and other parts under harsh high-dust conditions, thereby greatly improving the working reliability of the chute plate device in high-dust environments.
[0035] Among them, reference Figure 3The gear set may include a first gear 321, a second gear 322, and a rotary drive shaft 323. The output shaft of the drive motor 31 is coaxially connected to the first gear 321 to ensure that the power of the drive motor 31 is transmitted to the first gear 321 to make it rotate. The outer circumference of the first gear 321 meshes with the outer circumference of the second gear 322. The first gear 321 and the second gear 322 are connected by a straight vertical meshing method. This design not only ensures the stability of the transmission, but also allows them to withstand a large load through the external meshing connection. In the process of coal production and use, the chute device often needs to handle a large amount of material. Therefore, the transmission system needs to withstand a large torque and impact force. The straight vertical meshing external meshing gear design can effectively disperse these forces and ensure the reliability and durability of the transmission. The second gear 322 is connected to the chute body 1 through the rotary drive shaft 323, realizing the conversion from the rotational motion of the gear to the flipping motion of the chute body 1. When the drive motor 31 drives the first gear 321 to rotate, the second gear 322 will also rotate accordingly through the transmission between the gears. This, in turn, causes the rotary drive shaft 323 to drive the slag chute body 1 to flip, making the entire flipping process more stable and efficient, and meeting the actual needs of coal production and use. Specifically, the gear set and part of the rotary drive shaft 323 are housed inside the receiving cavity of the gear protective cover 33.
[0036] In the embodiments of this disclosure, the drive motor 31 is the power source of the drive assembly. It is located on the side of the mounting base 2 facing away from the chaff plate body 1. Through an external power input and the conversion of electrical energy, it provides the necessary power to the entire assembly. The gear protective cover 33 is sealed and fixed to the mounting base 2. The first gear 321, the second gear 322, and the gear protective cover 33 are all located on the side of the mounting base 2 facing the chaff plate body 1. The first gear 321 and the second gear 322 transmit the power of the drive motor 31 to the chaff plate body 1 through meshing transmission. Through the meshing connection of the gear set, the output shaft of the drive motor 31 can precisely drive the first gear 321 to rotate, thereby driving the second gear 322 and the rotary drive shaft 323 to rotate at the same speed and direction. This precise power transmission ensures that the chaff plate body 1 can rotate according to a predetermined trajectory and angle, improving the accuracy and reliability of the rotation action.
[0037] In some embodiments, refer to Figure 1 , Figure 5The chute body 1 may include a bucket section 11 and an outer frame section 12. The outer frame section 12 surrounds the edge of the bucket section 11 to form a bucket-shaped structure, which is the part that receives materials. The gravitational potential energy provided to the materials when the chute body 1 is tilted at a certain angle allows coal or other solid particles to slide smoothly down the chute body 1. The mounting base 2 may include a vertical plate 21 parallel to the outer frame section 12, a horizontal plate 22 perpendicular to the vertical plate 21, and reinforcing ribs 23 connecting the vertical plate 21 and the horizontal plate 22. The mounting bases 2 on both sides are connected to the outer frame section 12, serving to fix and support the chute body 1. The mounting bases 2 are firmly installed in appropriate positions, which can be adjusted according to the installation environment to ensure the stability and safety of the chute body 1. When it is necessary to guide coal or other solid particles to slide down, the drive assembly drives the chute plate body 1 to flip downward to an appropriate angle, so that the material can smoothly slide down to the predetermined area; when it is not needed, the drive assembly will flip the chute plate body 1 upward to retract, so as to avoid collision with other objects and cause structural interference.
[0038] In addition, the reinforcing ribs 23 can significantly enhance the structural strength of the vertical plate 21 and the horizontal plate 22. Since the entire chute plate body 1 often needs to withstand large vibrations and impacts during operation, the stability of the mounting base 2 is improved by adding the reinforcing ribs 23. On the other hand, the reinforcing ribs 23 also have a certain shielding effect, which can effectively block some dust and particles, reduce the possibility of entering the shaft system, and thus protect the internal components from damage.
[0039] In some embodiments, refer to Figure 5The vertical plate 21 may be provided with a motor mounting hole 211 and a gear shaft hole 212. The output shaft of the drive motor 31 passes through the motor mounting hole 211, and the rotary drive shaft 323 passes through the gear shaft hole 212 via a bearing 324. The motor mounting hole 211 facilitates the installation and fixation of the drive motor 31. Through the precisely designed motor mounting hole 211, the motor can be firmly installed on the mounting base 2, thereby ensuring the stable operation of the drive motor 31 and the reliability of its power output. The rotary drive shaft 323 passes through the gear shaft hole 212 and connects to the gear set, ensuring the precise positioning and stable operation of the rotary drive shaft 323. Bearing 324 is disposed on the inner wall of gear shaft hole 212. Bearing 324 can stably support rotary drive shaft 323, ensuring that it will not shift or wobble during rotation. It also ensures that the rotary drive shaft 323 contacts the inner ring of bearing 324 during rotation, rather than directly contacting the hole wall, effectively reducing friction and wear, thereby achieving smooth power transmission and extending the service life of rotary drive shaft 323 and mounting base 2. This bearing 324 can be a self-aligning roller bearing, which can automatically adjust the clearance between the bearing and the shaft, compensating for shaft misalignment caused by installation errors, thermal expansion, etc., thus ensuring stable operation and long service life of the bearing. It also has high load-bearing capacity and good impact resistance, maintaining excellent working performance under harsh working conditions.
[0040] As an exemplary embodiment of this disclosure, reference is made to Figure 4 A bearing cover 4 can be fitted onto the side of the rotary drive shaft 323 located on the vertical plate 21 away from the gear protective cover 33. The bearing cover 4 is used to seal the side of the gear shaft hole 212 away from the gear protective cover 33. After installation, the bearing cover 4 can fit tightly against the gear shaft hole 212, effectively preventing external dust, particles or other impurities from entering the shaft hole, avoiding failures such as wear and jamming of the bearing 324, which seriously affect the performance and life of the device.
[0041] Furthermore, referring to Figure 4 A labyrinth seal 5 can be provided between the bearing cover 4 and the rotary drive shaft 323. The labyrinth seal 5 has a series of sequentially arranged annular sealing teeth, and the teeth form a series of intercepting gaps and expansion cavities. When fine particles from the outside enter the bearing 324, they generate a throttling effect when passing through the gaps of the tortuous labyrinth, thereby achieving the purpose of blocking and further improving the dustproof capability of the device.
[0042] According to some embodiments, refer to Figure 4A spacer 6 can be fitted on the rotary drive shaft 323 between the bearing 324 and the gear guard 33. This effectively prevents direct contact or friction between the gear guard 33 and the bearing 324, which helps extend the service life of the bearing 324 and avoids premature wear or damage. Furthermore, the presence of the spacer 6 ensures a constant axial distance between the bearing 324 and the gear guard 33, preventing structural interference between components due to vibration or impact.
[0043] In some embodiments, refer to Figure 4 A cover plate 7 can also be provided at the connection between the rotary drive shaft 323 and the slag chute body 1 to effectively prevent external dust and particles from entering the connection between the rotary drive shaft 323 and the slag chute body 1. Since a large amount of dust often occurs during coal production and use, the sealing effect of the cover plate 7 can effectively isolate this dust, thereby reducing wear and jamming at the connection.
[0044] By rationally designing the parameters such as the number of teeth and module of the first gear 321 and the second gear 322, the transmission ratio can be amplified, enabling the drive motor 31 to output a larger torque at a lower speed, thereby improving the working efficiency and service life of the entire device. Thus, at low speeds, the power of the drive motor 31 can be transmitted through the first gear 321 and the second gear 322, ultimately driving the slag chute body 1 to rotate. The entire transmission process is highly efficient and stable, meeting the long-term operating requirements of the device under harsh conditions. In the embodiments of this disclosure, referring to... Figure 3 The diameter of the first gear 321 can be smaller than the diameter of the second gear 322. The output shaft of the drive motor 31 is connected to the first gear 321, and the output torque is transmitted to the first gear 321. Then, through the external meshing of the first gear 321 and the second gear 322, the speed is reduced and the torque is increased, ultimately achieving the required torque and speed.
[0045] Furthermore, the second gear 322 is connected to the rotary drive shaft 323 via a key 8, which ensures torque transmission capability and facilitates disassembly and maintenance. In addition, the rotary drive shaft 323 and the slag chute body 1, and the first gear 321 and the output shaft of the drive motor 31 can also be connected via keyes.
[0046] In some embodiments, a sealant may be provided between the gear guard 33 and the mounting base 2. The gap at the connection between the gear guard 33 and the vertical plate 21 of the mounting base 2 is filled with sealant, which further enhances the sealing effect and prevents dust particles and the like from entering the device through the gap.
[0047] The slag chute device fully considers the reliability of operation in high dust environments, effectively preventing dust and impurities from entering the device, thereby ensuring stable operation and long-term use of the device.
[0048] First, the gear guard 33 completely encloses the gear and shaft system, forming a relatively closed environment that effectively isolates external dust and particles. Second, the drive motor 31 and the side plate of the mounting base 2 form a seal through the centering action of the stop, ensuring a tight fit between the motor and the mounting base and preventing dust from entering through the interface. Finally, the sealing design for the second gear 322 and bearing 324 utilizes a labyrinth seal 5 to effectively block dust from entering. The labyrinth seal 5, with its complex structure, causes dust to be blocked and deflected multiple times during passage, greatly reducing the possibility of dust entering the shaft system. This design not only protects the bearings and gears from dust but also extends their service life.
[0049] In summary, this slag chute device, through the use of gear protective covers, sealant to fill gaps, centering seals, and labyrinth seals, creates a reliable sealed environment, effectively preventing dust and impurities from entering the device. This not only improves the device's operational reliability in high-dust environments but also reduces maintenance costs and operational risks, providing more stable and efficient material conveying support for coal production and consumption.
