[0002] In coal mining, the annual emission of coal gangue reaches 600-800 million tons, and the cumulative accumulation exceeds 5 billion tons. The accumulation of coal gangue on the ground not only occupies land, pollutes water and air, but may also cause disasters such as spontaneous combustion and landslides. The use of coal gangue aggregate for underground filling is a common method of coal-based solid waste disposal. Generally, the coal gangue on the well is vertically dropped into the well through the feeding well.

[0003] In the prior art, the gravity of the gangue itself is usually used to accurately drop the gangue into the desired area through the feeding well, which greatly saves transportation and disposal costs. However, the gangue will have a large impact velocity due to the conversion of gravitational potential energy into kinetic energy during its fall. Therefore, the gangue will produce a large impact force on the wall or bottom of the feeding well, thereby causing damage to the feeding well structure, destroying the underground equipment, and generating a huge noise, which will damage the working environment. Summary of the invention

[0004] The invention provides a feeding device to solve the problem in the prior art that the feeding well is easily damaged during the falling process of coal gangue.

[0039] 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.

[0040] like Figure 1As shown, the present application provides a feeding device, which includes a well body 10, a plurality of buffer assemblies 20 and a power generation assembly 30. The well body 10 has a feeding chamber 11, an inlet 12 and an outlet 13, the inlet 12 and the outlet 13 are both connected to the feeding chamber 11, and the inlet 12 is located above the outlet 13. A plurality of buffer assemblies 20 are alternately arranged on both sides of the well body 10 along the extension direction of the well body 10, and the buffer assemblies 20 are used to buffer the movement of coal gangue. The power generation assembly 30 is arranged at the outlet 13, and the power generation assembly 30 is arranged opposite to the buffer assembly 20 near the outlet 13. The power generation assembly 30 includes a bracket 31, a generator wheel 32 and a generator 33. The generator wheel 32 is rotatably arranged on the bracket 31, and the generator wheel 32 is electrically connected to the generator 33. The coal gangue can drive the generator wheel 32 to rotate.

[0041] By applying the technical solution of the present application, the gangue enters the feeding chamber 11 through the inlet 12 and is discharged through the outlet 13. The buffer assembly 20 can buffer the falling of the gangue, thereby reducing the falling speed of the gangue, avoiding a large impact on the well body 10, and thus avoiding damage to the well body 10 and the underground equipment, thereby extending the service life of the well body 10 and the underground equipment. At the same time, multiple buffer assemblies 20 are alternately arranged along the extension direction of the well body 10, which can ensure the buffering effect on the gangue. In addition, by slowing down the falling speed of the gangue, the noise in the feeding process is reduced, and the dust generated by the crushing of the gangue is reduced, which is conducive to improving the underground working environment and protecting the ecological environment. At the same time, by setting the power generation assembly 30, the gangue can not only be effectively slowed down by the buffer assembly 20 when falling, reducing the impact and damage to the structure of the well body 10, but also its kinetic energy can be converted into electrical energy when the gangue impacts the power generation wheel 32, realizing energy recovery and utilization, and improving energy utilization efficiency.

[0042] Among them, in the prior art, coal gangue is easily broken when feeding, thereby changing its performance and affecting the underground filling support effect.

[0043] However, in the present application, multiple buffer assemblies 20 are alternately arranged along the extension direction of the well body 10, which can fully contact and buffer the falling coal gangue, reduce the breakage of the coal gangue during the falling process, maintain the integrity of the coal gangue aggregate, and ensure its supporting performance during underground filling.

[0044] Among them, an air blowing port is provided at the outlet 13 , the air blowing port is communicated with the feeding chamber 11 , and the air blowing port and the buffer assembly 20 close to the outlet 13 are located on the same side of the well body 10 .

[0045] The feeding device further includes a fan 41 and a drive structure 42. The fan 41 is disposed at the air outlet and is used to drive the gas to flow toward the direction close to the inlet 12 to buffer the falling of the coal gangue. The drive structure 42 is drive-connected to the fan 41, and the drive structure 42 is electrically connected to the generator 33.

[0046] By configuring in this way, the fan 41 can generate an upward airflow, thereby creating resistance to the falling coal gangue, further slowing down its falling speed, and working together with the buffer component 20, significantly improving the buffering effect and reducing the impact and breakage of the coal gangue during the falling process.

[0047] Furthermore, due to the electrical connection between the driving structure 42, the fan 41 and the generator 33, the electric energy generated by the gangue impacting the generator 33 can be used to drive the fan 41, and the airflow generated by the fan 41 can buffer the gangue, thereby realizing efficient recycling of energy and reducing the overall energy consumption of the feeding device.

[0048] In this application, the driving structure 42 is a motor.

[0049] Specifically, the buffer assembly 20 includes a buffer structure 21 having a buffer surface 211. The buffer surface 211 has a feed end and a discharge end that are relatively arranged. The buffer surface 211 gradually tilts toward the center of the feeding chamber 11 along the direction from the feed end to the discharge end.

[0050] With such arrangement, the inclined buffer surface 211 can effectively guide the sliding path of the coal gangue, allowing the coal gangue to slide more smoothly from the feed end to the discharge end, avoiding the impact on the bottom of the well caused by direct vertical fall, while also reducing the irregular movement of the coal gangue during the falling process, thereby improving the stability and controllability of the coal gangue transmission.

[0051] In addition, the inclined design of the buffer surface 211 can slow down the falling speed of the coal gangue, and through the interaction of friction and gravity, the kinetic energy of the coal gangue is gradually converted into heat energy and friction loss, thereby effectively reducing the impact force of the coal gangue on the well body 10 and reducing the wear of the equipment and the well body 10.

[0052] Furthermore, the buffer surface 211 has an arc-shaped structure.

[0053] In this way, the arc structure can more evenly disperse the impact force of the gangue when it falls, avoiding the situation where the local force is too large. When the gangue contacts the arc buffer surface 211, its impact energy will be dispersed along the curve direction, thereby reducing the direct impact on the buffer structure 21 and the well body 10.

[0054] Wherein, a first buffer pad is arranged on the buffer surface 211 .

[0055] With such arrangement, the first buffer pad can absorb part of the impact force when the gangue falls, reduce the hard collision between the gangue and the buffer surface 211, thereby reducing the breakage rate of the gangue, maintaining the integrity and filling performance of the gangue, and the first buffer pad can further reduce the falling speed of the gangue.

[0056] Furthermore, the first buffer pad can protect the buffer structure 21 from excessive wear, extend the service life of the buffer structure 21, and reduce maintenance and replacement costs. Meanwhile, the first buffer pad can reduce the noise generated during the falling process of the coal gangue.

[0057] Optionally, the first buffer pad may be made of rubber material.

[0058] Specifically, the buffer assembly 20 further includes a connecting frame 22 and a buffer wheel 23. The connecting frame 22 is fixed to the inner wall of the feeding chamber 11, and the connecting frame 22 is located below the buffer structure 21. The buffer wheel 23 is rotatably arranged on the connecting frame 22, and the buffer wheel 23 is arranged at the discharge end of the buffer surface 211.

[0059] In this configuration, the buffer wheel 23 can provide a smooth transition for the gangue. When the gangue slides over the buffer surface 211 and reaches the discharge end, the rotation of the buffer wheel 23 can further slow down the speed of the gangue, reduce its impact force on subsequent equipment or the ground, protect the equipment from damage, and reduce the breakage of the gangue.

[0060] Furthermore, a second buffer pad is provided on the surface of the buffer wheel 23 .

[0061] With such arrangement, the second buffer pad can absorb part of the impact force when the gangue falls, reduce the hard collision between the gangue and the buffer wheel 23, thereby reducing the breakage rate of the gangue, maintaining the integrity and filling performance of the gangue, and the second buffer pad can further reduce the falling speed of the gangue.

[0062] In addition, the second buffer pad can protect the buffer wheel 23 from excessive wear, extend the service life of the buffer wheel 23, and reduce maintenance and replacement costs. At the same time, the second buffer pad can reduce the noise generated during the falling process of coal gangue.

[0063] In the present application, the buffer wheel 23 includes a fixed cylinder and a plurality of buffer blades, and the fixed cylinder is rotatably arranged on the connecting frame 22. The plurality of buffer blades are arranged on the fixed cylinder, and the plurality of buffer blades are arranged at intervals along the circumference of the fixed cylinder.

[0064] Specifically, the feeding device further includes a guide structure 50 .

[0065] The guide structure 50 is arranged close to the generator wheel 32 and is located on the side where the generator wheel 32 drops materials. The cross-sectional area of ​​the guide structure 50 gradually decreases in the direction away from the generator wheel 32 . The guide structure 50 is used to guide the coal gangue dropped from the generator wheel 32 .

[0066] In this way, the guide structure 50 can ensure that the gangue is accurately guided along a predetermined path when it falls from the power generation wheel 32 to the next-level structure or the required area, thereby avoiding random scattering of the gangue and reducing accidental impacts on the well wall or other equipment.

[0067] Moreover, as the cross-sectional area of ​​the guide structure 50 gradually decreases, the gangue will gradually gather in a smaller area during the sliding process, which helps to reduce the secondary scattering after the gangue collides with the guide structure 50, reduces the additional impact of the gangue on the surrounding structure, and protects the well wall and other equipment.

[0068] Furthermore, the feeding device also includes a first conveyor belt 61 and a second conveyor belt 62 .

[0069] The first conveyor belt 61 is disposed at the inlet 12 . The second conveyor belt 62 is disposed at the outlet 13 , and the second conveyor belt 62 is disposed close to the guide structure 50 , and the second conveyor belt 62 is located at a side of the guide structure 50 away from the power generation wheel 32 .

[0070] Such a configuration facilitates the transportation of the gangue into the feeding chamber 11 and the transportation of the gangue to the desired area. The first conveyor belt 61 can accurately control the feeding position and speed of the gangue at the inlet 12, ensuring that it enters the feeding chamber 11 smoothly and reducing the scattering and impact at the beginning. The second conveyor belt 62 receives the buffered gangue at the outlet 13, further guides the gangue, ensures that it is evenly and stably transported to the next processing link, and avoids the accumulation or disorderly flow of the gangue at the outlet 13.

[0071] Specifically, in the present application, the second conveyor belt 62 is in contact with the guide structure 50 .

[0072] The power generation wheel 32 includes a connecting cylinder 321 and a plurality of power generation blades 322. The connecting cylinder 321 is rotatably arranged on the bracket 31. The plurality of power generation blades 322 are arranged on the connecting cylinder 321, and the plurality of power generation blades 322 are arranged at intervals along the circumference of the connecting cylinder 321.

[0073] In this way, the configuration of the power generation blades 322 can more effectively capture and convert the kinetic energy generated by the falling coal gangue. When the coal gangue hits the power generation blades 322, the rotation of the power generation blades 322 is more direct and powerful, which can significantly improve the efficiency of the generator wheel 32 in converting mechanical energy into electrical energy.

[0074] In addition, multiple power generation blades 322 are arranged at intervals along the circumference of the connecting tube 321, which can ensure that the kinetic energy of the coal gangue is evenly distributed on each power generation blade 322 when falling, avoiding single-point overload, making the operation of the power generation wheel 32 more stable and extending its service life.
