[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 6 As shown, the present invention provides a coal bunker transportation system, which includes a conveyor 10 and an anti-bumping channel 20. The conveyor 10 has a conveying surface 11, and the anti-bumping channel 20 is covered and arranged outside the conveyor 10. The extension direction of the anti-bumping channel 20 is the same as the conveying direction of the conveyor 10. The anti-bumping channel 20 has an anti-bumping cavity, and the bottom of the anti-bumping cavity has an opening 02. The conveying surface 11 is located at the opening 02, and the conveying surface 11 cooperates with the opening 02 to close the bottom of the anti-bumping cavity, and the material on the conveying surface 11 is located in the anti-bumping cavity.

[0043] By applying the technical solution of the present invention, the conveyor 10 has a conveying surface 11 for transporting materials such as coal. The conveyor 10 can be driven by a motor, and the tension of the belt is maintained by rollers and a tensioning device to ensure its stable operation. The anti-collapse channel 20 is covered on the outside of the conveyor 10, and its extension direction is the same as the conveying direction of the conveyor 10, forming a closed cavity along a portion of the length of the conveyor 10. The anti-collapse channel 20 has an anti-collapse cavity, which is used to temporarily store overflowed materials when the coal bunker 03 collapses, so as to prevent it from directly entering the operating room or the surrounding space, thereby protecting the safety of the operator. The bottom of the anti-collapse cavity has an opening 02, and the position of this opening 02 corresponds to a certain section of the conveying surface 11 of the conveyor 10. During normal operation, the conveying surface 11 of the conveyor 10 is located at the opening 02, forming a tight fit with the opening 02, and can close the bottom of the anti-collapse cavity. When the conveyor 10 is running, the material on the conveying surface 11 will move along the conveying direction without leaking from the opening 02.

[0044] Once the coal bunker 03 collapses, the collapse prevention channel 20 will automatically enter a closed state, and the materials will be temporarily stored in the collapse prevention chamber. After the collapse event is handled and confirmed to be safe, the materials in the collapse prevention chamber can be transported out by the conveyor 10, or the channel can be cleared manually to restore the normal operation of the system.

[0045] Specifically, one end of the conveyor 10 adopts a closed structure to prevent the collapsed materials from entering other conveying systems or operating areas. The other end of the conveyor 10 has a sufficient length for storing the collapsed materials.

[0046] like Figure 1 and Figure 4 As shown, the anti-bin collapse channel 20 includes a frame 21 and an inner tube 22. The frame 21 is arranged on the outer side of the conveyor 10 along the extension direction of the conveyor 10; the inner tube 22 is arranged on the frame 21, and the inner tube 22 has an anti-collapse cavity. In this embodiment, the frame 21 is the basic structure of the anti-bin collapse channel 20, and it is arranged on the outer side of the conveyor 10 along the extension direction of the conveyor 10 of the belt conveyor 10. The design of the frame 21 should take into account the position of the coal bunker 03 and the layout of the conveyor 10, to ensure that the channel can completely close the coal feeder outlet and the conveyor 10 within a certain range to prevent the overflow of the collapsed materials. The inner tube 22 is arranged on the frame 21, and an anti-collapse cavity is formed inside it. The shape and size of the bottom of the anti-collapse cavity should match the conveying surface 11 of the conveyor 10 to achieve seamless closure. The anti-collapse cavity of the inner tube 22 should have sufficient volume to temporarily store the collapsed materials to prevent them from overflowing into the surrounding environment.

[0047] Specifically, the material of the frame 21 should be selected from high-strength, wear-resistant steel to ensure that it can withstand the impact and weight of the materials when the coal bunker 03 collapses. The installation of the frame 21 should ensure that it is stable, and is usually fixed to the ground or the tunnel wall under the coal mine by anchor bolts to provide sufficient support and stability. The inner tube 22 should also be made of high-strength materials, and its design should take into account the type, density and fluidity of the conveyed materials to ensure that the inner tube 22 can withstand the impact and storage capacity of the collapsed materials, while ensuring that the materials can pass smoothly.

[0048] Furthermore, the frame 21 includes multiple frames 211 and multiple cross beams 212. The frame 211 has two relatively arranged longitudinal beams 2111, a top beam 2112 and a bottom beam 2113. The two longitudinal beams 2111 are located on both sides of the conveyor 10. The top beam 2112 is respectively connected to the tops of the two longitudinal beams 2111, the bottom beam 2113 is respectively connected to the middle parts of the two longitudinal beams 2111, and the bottom beam 2113 is located above the conveyor 10. The multiple frames 211 are spaced apart along the extension direction of the conveyor 10, and the cross beams 212 are respectively connected to the multiple frames 211. In this embodiment, the frame 211 is composed of two longitudinal beams 2111, a top beam 2112 and a bottom beam 2113. The longitudinal beams 2111 are arranged on both sides of the belt conveyor 10. The top beam 2112 is connected to the top of the longitudinal beam 2111, and the bottom beam 2113 is connected to the middle of the longitudinal beam 2111. The bottom beam 2113 is located above the belt conveyor 10, which ensures the stability of the frame 21 and the integrity of the closed passage. Multiple frames 211 are distributed in sequence along the extension direction of the belt conveyor 10. This distribution method can ensure the structural strength and stability of the entire closed passage. The crossbeam 212 can further strengthen the connection between the frames 211 and improve the stability of the entire frame 21. The crossbeam 212 is connected to multiple frames 211 and is distributed at the top, middle and bottom of the frames 211 to form a solid overall structure.

[0049] Furthermore, the inner cylinder 22 is fixedly connected to the inner side of the multiple frames 211, the inner cylinder 22 is fixedly connected to the longitudinal beam 2111 and the top beam 2112, the width of the bottom of the inner cylinder 22 gradually decreases from the direction close to the conveying surface 11, and the size of the opening 02 of the inner cylinder 22 is adapted to the size of the conveying surface 11. In this embodiment, the inner cylinder 22 has a certain inclination angle, and its bottom width gradually decreases from one end close to the belt surface of the conveyor 10, which can effectively cooperate with the conveying surface 11 and seal the materials on the conveying surface 11. The size of the opening 02 of the inner cylinder 22 matches the width of the belt surface of the conveyor 10, ensuring that the materials can be smoothly transferred, ensuring sealing and reducing the risk of material leakage during the collapse process.

[0050] Furthermore, a vent 23 is provided on the side wall of the anti-bin collapse channel 20, and the vent 23 is provided near the top of the anti-bin collapse channel 20. In this embodiment, in order to ensure the ventilation effect inside the channel, and taking into account the direction and pressure of material flow during a bin collapse, the vent 23 is provided at the top of the channel, which can effectively utilize the principle of natural convection and improve the ventilation efficiency inside the channel. Moreover, when a bin collapse occurs, materials usually flow out from the bottom of the coal bunker 03 into the channel, and due to the effect of gravity, materials tend to gather at the bottom of the channel. Setting the vent 23 at the top can prevent materials from flowing out through the vent 23 during a bin collapse, thereby improving the operating safety of operators.

[0051] Specifically, the vent 23 is designed to be openable and closable. Normally, it is opened to maintain air circulation inside the passage. When the coal bunker 03 collapses, due to the impact force or pressure of the material, the vent 23 can be automatically closed to prevent the material from entering the area connecting the passage and the operating room, thereby protecting the safety of personnel. Due to its high position, the possibility of being blocked by materials during daily operations can be reduced.

[0052] Furthermore, a window 24 is provided at the vent 23, the window 24 is located inside the anti-crash passage 20, and the rotating shaft of the window 24 is located directly below the vent 23, the window 24 rotates toward the inside of the anti-crash passage 20 to open the vent 23, and the window 24 rotates toward the outside of the anti-crash passage 20 to close the vent 23. In this embodiment, the window 24 is a rotatable structure, and a rotating shaft is provided at one end of the window 24, and the rotating shaft is installed on the side of the vent 23 close to the conveying surface 11, so as to ensure that the window 24 can smoothly switch between the inside and outside of the vent 23 when rotating, and the other end of the window 24 is inclined toward the anti-crash passage 20 and remains in an open state. The size of the window 24 should match the size of the vent 23, so as to ensure that the vent 23 can be completely covered in a closed state to prevent the collapsed materials from entering the interior of the passage.

[0053] When the coal bunker 03 collapses and the materials rush to the passage, the pressure of the materials pushes the baffle 24 toward the outside of the passage, causing it to automatically close the vent 23, preventing the materials from entering other areas of the passage and ensuring internal safety. After the collapse event, the baffle 24 can automatically reset to the open state to restore the ventilation function of the passage. The reset mechanism can be a spring device, pneumatic or hydraulic drive system to ensure that the baffle 24 can automatically or manually return to the initial open position when the external pressure disappears.

[0054] Furthermore, the anti-break-up channel 20 has a plurality of vents 23 and a plurality of baffles 24, and the plurality of vents 23 are spaced apart along the extension direction of the anti-break-up channel 20, and the vents 23 and the baffles 24 are arranged in a one-to-one correspondence. In the present embodiment, the anti-break-up channel 20 is designed with a plurality of vents 23, and these vents 23 are evenly spaced apart along the extension direction of the channel. The number and position of the vents 23 should be reasonably planned according to the length, width and height of the channel to ensure uniform air circulation. The structure of the baffle 24 needs to take into account both ventilation and sealing functions, and can remain open in normal ventilation conditions, and quickly close in an emergency to form a sealed window to prevent the coal flow from entering the internal space of the channel.

[0055] Furthermore, the frame 21 also includes a reinforcing beam 213, which is arranged on the outside of the frame 211, and the extending direction of the reinforcing beam 213 and the cross beam 212 has an angle, and the reinforcing beam 213 is fixedly connected to the multiple frames 211. In this embodiment, the reinforcing beam 213 is used to enhance the lateral stability of the frame 211 and improve the bearing capacity and impact resistance of the entire system. The reinforcing beam 213 and the extending direction of the cross beam 212 have a certain angle, and this structure can effectively disperse and offset the force transmitted along the direction of the cross beam 212, reduce the local force of the frame 211, and avoid structural damage caused by the huge impact force of the coal flow when the warehouse collapses. The reinforcing beam 213 is arranged on the outside of the frame 211, and forms an oblique support with the cross beam 212. It is usually installed at the key connection point between the longitudinal beam 2111 of the frame 211 and the cross beam 212, which can ensure that each frame 211 can obtain effective oblique support and improve the structural strength of the entire system.

[0056] Furthermore, the frame 21 includes a plurality of reinforcing beams 213, which are sequentially arranged on the outer wall of the frame 211 along the extension direction of the conveyor 10, and one end of each reinforcing beam 213 extends to the top beam 2112, and the other end of each reinforcing beam 213 extends to the bottom beam 2113, and the extension directions of two adjacent reinforcing beams 213 have an angle.

[0057] In this embodiment, the reinforcing beam 213 needs to consider the extension direction of the conveyor 10, ensuring that one end of each reinforcing beam 213 can extend to the top beam 2112, and the other end extends to the bottom beam 2113, forming a continuous support structure from top to bottom, so as to improve the overall strength of the frame 21. Among them, multiple reinforcing beams 213 are arranged in sequence along the extension direction of the conveyor 10, and each section of the reinforcing beam 213 forms a certain angle with the extension direction of the next reinforcing beam 213, which can disperse the impact force of the material and reduce the load borne by a single reinforcing beam 213, while increasing the complexity and strength of the structure and improving its ability to resist deformation and damage. The angle selection of the reinforcing beam 213 needs to be calculated and optimized according to the width of the conveyor 10, the material properties of the coal bunker 03 and the expected bunker collapse force, so as to achieve the best support effect.

[0058] Furthermore, the conveyor 10 has a feed end 101 and a discharge end 102 that are relatively arranged, and the coal bunker transportation system also includes a coal bunker 03. The coal bunker 03 has a discharge port 031, and the discharge port 031 is located above the feed end 101. One end of the anti-bunkering channel 20 is located at the confluence of the discharge port 031 and the feed end 101. In this embodiment, the coal bunker transportation system mainly includes three parts: the belt conveyor 10, the anti-bunkering channel 20 and the coal bunker 03. The belt conveyor 10 has a feed end 101 and a discharge end 102, wherein the feed end 101 is located below the discharge port 031 of the coal bunker 03, and is used to receive the coal that falls from the coal bunker 03 through the discharge port 031. One end of the anti-breach passage 20 is precisely positioned at the intersection of the coal bunker 03 discharge port 031 and the conveyor 10 feed end 101, forming a closed transition area for temporarily storing overflowed coal when the coal bunker 03 collapses, preventing it from causing damage to the operating room or the conveyor 10 below.

[0059] One end of the anti-breach channel 20 needs to be tightly connected to the discharge port 031, and the other end is connected to the feed end 101 of the conveyor 10 to ensure that the coal can be smoothly transferred to the conveyor belt. The anti-breach channel 20 remains open during normal operation, allowing the coal to fall freely onto the conveying surface 11 of the conveyor 10. When the coal bunker 03 collapses, the closed structure of the channel can prevent a large amount of coal from directly impacting the conveyor 10 or the surrounding environment, protecting the safety of the operator.
