Description

Technical Field

[0001] This utility model relates to the field of coal mine conveyor technology, and in particular to a lateral guide plate chute for coal mine mineral transportation that prevents deviation. Background Technology

[0002] Coal mine mineral transport guide chutes are a key component connecting the transfer points of underground transport equipment. Essentially, they are robust metal guide channels. Their core function is to receive and guide materials such as coal to be smoothly and orderly transferred from one piece of equipment to the next, much like a "controlled slide." Their importance lies in not only ensuring the continuity and efficiency of the transport process, but also in effectively controlling dust emissions, reducing coal breakage rates, and preventing material blockages and spills through their structure. Thus, they play an indispensable role in ensuring safe production, protecting equipment, improving coal quality, and enhancing the working environment.

[0003] However, traditional fixed baffles cannot be dynamically adjusted according to the force and direction of mineral deviation, and cannot accurately correct deviation, which makes it easy for minerals to accumulate and blockage, affecting transportation efficiency. At the same time, when subjected to high load impact, the overall structure of the chute is prone to deformation or damage, affecting its service life and normal operation. Furthermore, the inner wall of the chute is in direct contact with the minerals and is subjected to friction and impact for a long time, resulting in rapid wear and requiring frequent maintenance and replacement.

[0004] Therefore, we provide a side guide plate chute for coal mine mineral transportation to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a side guide plate chute for coal mine mineral transportation to prevent deviation and solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a support column, a base plate is fixedly connected to the upper end of the support column, a side plate is fixedly connected to the right side of the base plate, an adaptive anti-deviation guide component is installed on the right side of the side plate, an extension plate is welded to the right side of the side plate, a guide plate is provided above the extension plate, an elastic buffer and friction reduction component is installed on the upper surface of the base plate, and an installation base is installed on the upper surface of the base plate, with an installation groove formed on the surface of the installation base.

[0007] Preferably, the base plate has side plates on both sides, and the side plates have the same structure. The base plate and the side plates are welded together, and the base plate and the side plates are reinforced by triangular reinforcing ribs.

[0008] Preferably, an angle adjustment rod is passed through the rear interior of the guide plate, and the angle adjustment rod passes through the guide plate and the extension plate to form a rotating structure. A ball bearing is fixedly connected to the front interior of the extension plate.

[0009] Preferably, the upper surface of the extension plate is provided with a groove, and a return spring is provided on the side of the ball bearing shaft away from the bottom plate. The return spring is installed inside the groove and abuts against the ball bearing shaft, and the ball bearing shaft slides along the groove.

[0010] Preferably, a buffer spring is installed on the inner side of the mounting groove, the mounting base is a steel block, and the mounting base is fixed to the surface of the base plate by bolts.

[0011] Preferably, the upper end of the buffer spring is provided with a friction-reducing liner, the friction-reducing liner is made of silicon carbide ceramic material, the buffer spring abuts against the friction-reducing liner, and the buffer spring is evenly distributed on the surface of the friction-reducing liner.

[0012] Preferably, the friction-reducing liner covers the inner walls of the bottom plate and the two sets of side plates, the length of the friction-reducing liner is the same as the length of the bottom plate, and the height of the friction-reducing liner is the same as the height of the side plates.

[0013] This utility model provides a lateral guide plate chute for preventing deviation in coal mine mineral transportation. Compared with the prior art, it has the following advantages:

[0014] 1. This type of anti-deviation side guide chute for coal mine mineral transportation features an angle adjustment rod rotation structure that adaptively adjusts the guide angle according to the force and direction of mineral deviation, accurately correcting deviation and guiding the mineral back to its trajectory, avoiding accumulation and blockage, ensuring continuous transportation. The sliding cooperation between the extension plate chute and the guide plate ball shaft reduces friction and jamming. The return spring enables the guide plate to automatically reset, improving automation and reusability. The welding and stress dispersion design of the extension plate enhances structural stability, enabling it to withstand high-load impacts and extending its service life. At the same time, the symmetrical installation of the guide plate and the side plate form double protection, reducing the force and frequency of mineral impact on the side plate, reducing side leakage losses and environmental pollution.

[0015] 2. This type of anti-deviation lateral guide plate chute for coal mine mineral transportation utilizes high-hardness silicon carbide ceramic lining plates to fully cover the inner wall of the chute. This concentrates the friction and impact of minerals onto the lining plates, significantly reducing wear on the main structure and solving the problems of short lifespan and frequent maintenance of traditional chutes. Multiple sets of buffer springs evenly distributed within the mounting base can simultaneously compress and absorb impact energy, preventing localized damage to the lining plates. Simultaneously, it weakens the transmission of impact force, reduces chute vibration and stress concentration, and ensures overall stability. The bolt-fixed design of the steel base ensures a secure installation without displacement, guaranteeing the continuous effectiveness of the buffer and wear-reducing function. Its high wear resistance and impact resistance extend the lifespan of components and the chute, reducing replacement and maintenance costs, while also lowering the incidence of transportation failures and ensuring continuous and efficient operation.

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a lateral guide chute for coal mine mineral transportation to prevent deviation, including a support column 1, a base plate 2 fixedly connected to the upper end of the support column 1, a side plate 3 fixedly connected to the right side of the base plate 2, an adaptive anti-deviation guide component 4 installed on the right side of the side plate 3, an extension plate 401 welded to the right side of the side plate 3, a guide plate 402 provided above the extension plate 401, an elastic buffer and wear reduction component 5 installed on the upper surface of the base plate 2, and an installation base 501 installed on the upper surface of the base plate 2, with an installation groove 502 opened on the surface of the installation base 501.

[0023] Both sides of the base plate 2 are provided with side plates 3, and the side plates 3 have the same structure. The base plate 2 and the side plates 3 are welded together, and the base plate 2 and the side plates 3 are reinforced by triangular reinforcing ribs.

[0024] During use, side plates 3 with the same structure are set on both sides of the base plate 2 to symmetrically form a closed transport side wall, which doubles the prevention of mineral leakage. At the same time, triangular reinforcing ribs are added at the connection between the base plate 2 and the side plate 3. The stress generated by the impact of minerals is dispersed by the principle of triangular stability. When working, the force generated by the impact of minerals on the side plate 3 is transmitted to the base plate 2 through the welding joint. The triangular reinforcing ribs further offset the stress, prevent the side plate 3 from deforming or separating from the base plate 2, and maintain the integrity of the channel.

[0025] An angle adjustment rod 403 is inserted through the rear side of the guide plate 402, and the angle adjustment rod 403 passes through the guide plate 402 and forms a rotating structure with the extension plate 401. A ball bearing shaft 404 is fixedly connected to the front side of the extension plate 401.

[0026] During transportation, the angle adjustment rod 403 passes through the guide plate 402 and is connected to the extension plate 401. When the mineral is transported off course, the angle adjustment rod 403 can adjust the angle of the guide plate 402 to prevent excessive mineral accumulation from damaging the guide plate 402. When the guide plate 402 changes angle, the ball bearing shaft 404 moves along the slide groove 405 to assist the movement of the guide plate 402.

[0027] The upper surface of the extension plate 401 is provided with a groove 405. A return spring 406 is provided on the side of the ball shaft 404 away from the bottom plate 2. The return spring 406 is installed inside the groove 405 and abuts against the ball shaft 404. The ball shaft 404 slides along the groove 405.

[0028] During operation, the mineral impacts the guide plate 402, causing the ball bearing shaft 404 to slide along the groove 405, simultaneously compressing the reset spring 406 to store elastic potential energy. When the mineral leaves the guide plate 402, the reset spring 406 releases its potential energy, pushing the ball bearing shaft 404 to slide in the opposite direction along the groove 405, causing the guide plate 402 to return to its initial angle around the angle adjustment rod 403, waiting for the next offset correction.

[0029] A buffer spring 503 is installed on the inner side of the mounting slot 502. The mounting base 501 is a steel block and is fixed to the surface of the base plate 2 by bolts.

[0030] During mineral transportation, the force generated by the impact of the mineral is transmitted to the buffer spring 503 through the upper component. The spring is compressed and absorbs energy in the mounting groove 502. The mounting base 501 is fixedly connected to the base plate 2 by bolts, which transmits the force to the support column 1 to prevent the buffer component from shifting.

[0031] The upper end of the buffer spring 503 is provided with a friction-reducing liner 504. The friction-reducing liner 504 is made of silicon carbide ceramic material. The buffer spring 503 abuts against the friction-reducing liner 504, and the buffer spring 503 is evenly distributed on the surface of the friction-reducing liner 504.

[0032] When minerals rub against the friction-reducing liner 504, the silicon carbide ceramic material resists wear. At the same time, the force generated by the minerals impacting the friction-reducing liner 504 is transmitted to the evenly distributed buffer springs 503 below. The buffer springs 503 are compressed simultaneously to absorb the impact force, preventing the friction-reducing liner 504 from being damaged by excessive local stress and extending the service life of the component.

[0033] The friction-reducing liner 504 covers the inner walls of the base plate 2 and the two sets of side plates 3. The length of the friction-reducing liner 504 is the same as the length of the base plate 2, and the height of the friction-reducing liner 504 is the same as the height of the side plates 3.

[0034] During the transportation of minerals in the chute, whether they come into contact with the upper surface of the bottom plate 2 or the inner wall of the side plates 3, they only interact with the wear-reducing liner 504. This concentrates wear and impact on the wear-reducing liner 504, directly protecting the original structure of the bottom plate 2 and the side plates 3, and minimizing the overall maintenance cost of the chute.

[0035] Working principle: When using this guide plate chute, after the mineral enters the chute, it slides and is transported on the friction-reducing liner 504 on the upper surface of the bottom plate 2. The side plates 3 on both sides form a double closed sidewall to prevent the mineral from leaking to both sides. The impact force generated on the side plates 3 during the mineral transportation process is transmitted to the bottom plate 2 through the welded joint. The triangular reinforcing ribs disperse and offset the stress, preventing the side plates 3 from deforming and separating from the bottom plate 2, and maintaining the integrity of the channel.

[0036] Subsequently, when the mineral transport deviates and impacts the guide plate 402, the impact force pushes the guide plate 402 to rotate around the angle adjustment rod 403, while simultaneously driving the ball bearing shaft 404 to slide along the groove 405 on the extension plate 401. During the sliding process, the ball bearing shaft 404 compresses the reset spring 406 and stores elastic potential energy. The angle of the guide plate 402 is adaptively adjusted to guide the deviated mineral back to the normal transport trajectory and prevent mineral accumulation from damaging the guide plate 402.

[0037] Next, during transportation, the mineral comes into direct contact with the friction-reducing liner 504. The friction-reducing liner 504, made of silicon carbide ceramic, effectively resists wear. At the same time, the impact force of the mineral on the friction-reducing liner 504 is transmitted to the evenly distributed buffer springs 503 below. The buffer springs 503 are compressed and absorb the impact energy in the mounting groove 502 of the mounting base 501, reducing the impact force on the base plate 2 and the side plate 3. The mounting base 501 transmits part of the force to the support column 1, ensuring that the buffer assembly does not shift.

[0038] Finally, after the deviated mineral is corrected by the guide plate 402, the impact force of the mineral on the guide plate 402 disappears. The reset spring 406 releases the stored elastic potential energy, pushing the ball shaft 404 to slide in the opposite direction along the chute 405, causing the guide plate 402 to return to the initial guide angle around the angle adjustment rod 403, waiting for the next deviation correction. At the same time, the buffer spring 503 rebounds and pushes the anti-friction liner 504 back to the initial position, continuously providing buffer and anti-friction protection for the minerals transported subsequently. This completes the use of a side guide plate chute for preventing deviation in coal mine mineral transportation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
