DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1-15 As shown, an embodiment of the present invention provides a mining belt conveyor roller, comprising:

[0042] The support plate 1 has mounting notches 101 evenly arranged around its circumference;

[0043] refer to Figure 1 、 Figure 5 The support plate 1 can provide support force for multiple contact components 2 so that the pressure can be transmitted to the rotating shaft 401; the installation notch 101 is used for installing the contact components 2.

[0044] The rotation assembly 4 is concentrically fixed in the support plate 1; the rotation assembly 4 includes a rotation shaft 401, a mounting cavity 402 is provided in the rotation shaft 401, and an end frame 404 is fixedly connected to the outer end of the rotation shaft 401. The end frame 404 is provided with a pressure assembly for applying an axial force;

[0045] refer to Figure 10The rotating shaft 401 is used to bear the force and is conveniently installed on the bearing seat, which is convenient for installation and use in the mine. The installation cavity 402 provides installation space for the installation cylinder 602 and the moving rod 607.

[0046] The pressure assembly includes an adjustment screw 405 concentrically threadedly mounted on the end frame 404. The inner end of the adjustment screw 405 extends into the inner side of the end frame 404 and is fixedly connected to an outer contact seat 406. A pressure spring 407 is fixedly connected to the inner side of the outer contact seat 406. The pressure spring 407 and the inner contact seat 606 are in contact with each other.

[0047] refer to Figure 10 During the pressure operation, the deformed pressure spring 407 can provide an axial inward or outward force. When an axial inward force is provided, this pressure will be transmitted to the inner contact seat 606, and then the axial piston head 608 will be driven to move through the moving rod 607. The axial movement of the axial piston head 608 will squeeze the oil in the main support shell 601, providing the necessary hydraulic pressure for the rise of the support rod 603; when an axial outward force is provided, this pulling force will be transmitted to the inner contact seat 606, and then the axial piston head 608 will be driven to move through the moving rod 607. The axial movement of the axial piston head 608 will extract the oil in the main support shell 601, providing the necessary space for the descent of the support rod 603.

[0048] The contact assembly 2 is arranged in the mounting notch 101. The contact assembly 2 includes a long arm 201 and a short arm 204. A movable seat 206 is symmetrically slidably connected in the short arm 204. A tension spring 207 is fixedly connected between the two movable seats 206. The movable seat 206 rotates with the long arm 201 on the same side. The lower part of the short arm 204 is fixedly connected to a connecting seat 208. The outer end of the long arm 201 extends into the mounting notch 101 and rotates with the support plate 1.

[0049] refer to Figure 6 、 Figure 7, the long arm 201 will rotate under the action of the rising or falling of the short arm 204, so the long arm 201 can move clockwise or counterclockwise. When the long arm 201 rotates clockwise, the short arm 204 is lower than the long arm 201, and the conveyor belt on the contact component 2 will follow and deform downward. At this time, the conveyor belt is in a stressed state, which can provide space for the transportation of ore materials and prevent the ore materials from falling, which is suitable for mining transportation; when the long arm 201 rotates counterclockwise, the short arm 204 is higher than the long arm 201, and the conveyor belt on the contact component 2 will follow and deform upward. At this time, the upwardly convex conveyor belt can prevent rainwater and debris from falling on it, which is suitable for use in non-working conditions, and prevents rainwater and impurities from accumulating on the conveyor belt in the mine, corroding the conveyor belt, and extending the service life of the conveyor belt and rollers; the tension spring 207 can be stretched under stress, so it can meet the lateral displacement when the long arm 201 rotates. This tension spring 207 can also provide a preliminary buffering effect when the ore materials are dropped.

[0050] The upper portion of the long arm 201 is fixedly connected to a long contact pad 202, and the outer end of the long contact pad 202 is fixedly connected to an upward-swinging member 203. The upper portion of the short arm 204 is fixedly connected to a short contact pad 205. The long contact pad 202 and the short contact pad 205 are made of any one of rubber, nylon, and ceramic. The upward-swinging member 203 is made of rubber. A buffer cavity 2032 is provided on the upper portion of the upward-swinging member 203, and the buffer cavity 2032 is filled with a plurality of buffer balls 2031.

[0051] refer to Figure 6 、 Figure 15 The long contact pad 202 and the short contact pad 205 are used to contact the inner side of the conveyor belt to provide the necessary support force for the conveyor belt. The materials of the long contact pad 202 and the short contact pad 205 can be selected according to the usage scenario. For example, in a coal mine environment, ceramic material is used; since the upward part 203 is located on the outside of the conveyor belt, it can prevent the conveyor belt from shifting in the lateral direction and has the function of correcting the conveyor belt. At the same time, the upward part 203 located on the outside of the conveyor belt is also more likely to be hit by falling ore. When the upward part 203 is hit, the buffer cavity 2032 on its upper part will be deformed, squeezing the multiple buffer balls 2031 inside. The mutual rolling and squeezing of the multiple buffer balls 2031 can absorb part of the impact force, thereby preventing the upward part 203 from being directly hit, thereby improving the service life of the upward part 203.

[0052] Auxiliary support assembly 3, the auxiliary support assembly 3 is fixed on the rotating shaft 401, and is used to provide auxiliary support for the long arm 201; the auxiliary support assembly 3 includes an annular shell 301 fixedly mounted on the rotating shaft 401, and the inner circumference of the annular shell 301 is evenly provided with a recoverable airbag 306, and the recoverable airbag 306 is fixedly connected with an air pipe 303, and the air pipe 303 extends out of the annular shell 301, and a movable seat 304 is provided on the recoverable airbag 306, and the movable seat 304 is slidably matched with the annular shell 301, and the upper part of the movable seat 304 extends out of the annular shell 301 and is rotatably connected to the contact wheel 305, and the contact wheel 305 is in contact with the long arm 201; the air outlet of the air pipe 303 is inclined, and the air outlet is rotatably connected to the blocking net 302;

[0053] refer to Figure 1 、 Figure 8 、 Figure 9 Since there is air in the recoverable airbag 306, it cannot provide rigid support until the air inside it is completely exhausted. Because there is air in the recoverable airbag 306, when the contact wheel 305 is compressed, the squeezing force can be transmitted to the recoverable airbag 306. The compressed gas inside the recoverable airbag 306 is blown out from the air outlet of the air pipe 303. Since the air outlet is small, it takes a certain amount of time for the gas to be released. This feature can provide a cushioning effect for the long arm 201.

[0054] When the gas in the recoverable airbag 306 is completely exhausted, the contact wheel 305 and the movable seat 304 can provide rigid support for the long arm 201, ensuring that the long arm 201 is well stressed. The blocking net 302 can prevent foreign matter from entering from the air outlet and can also block a portion of the air outlet space. Therefore, the air outlet will be further reduced, thereby enhancing the effect of the buffering function.

[0055] When the contact wheel 305 is not under force, the recoverable airbag 306 utilizes its own property of recovering to its original shape to re-absorb external gas into it, thereby providing a buffering function for the next large impact; if the deformation of the recoverable airbag 306 is small, then it takes a short time to recover to its original shape, which is suitable for buffering small impact forces.

[0056] The main support assembly 6 is arranged between the two rotating shafts 401. The main support assembly 6 includes a main support shell 601. The longitudinal section of the main support shell 601 is a regular hexagon. The main support shell 601 is filled with oil. Both ends of the main support shell 601 are fixedly connected to the mounting cylinder 602. The mounting cylinder 602 is sealed and slidably connected to the axial piston head 608. The outer end of the axial piston head 608 is fixedly connected to the moving rod 607. The outer end of the moving rod 607 is fixedly connected to the inner contact seat 606. The upper circumference of the main support shell 601 is evenly fixedly connected to the support cylinder 604. The support cylinder 604 is sealed and slidably connected to the radial piston head 605. The outer end of the radial piston head 605 is fixedly connected to the support rod 603. The support rod 603 rotates with the connecting seat 208.

[0057] The main support housing 601 is fixedly connected to the rotation shaft 401, the movable rod 607 passes through the mounting cavity 402, and the inner contact seat 606 contacts the pressure part of the pressure assembly;

[0058] refer to Figure 3 、 Figure 4 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 Under the action of oil pressure, the support rod 603 can provide supporting force for the connecting seat 208. Since the amount of oil in the main support shell 601 remains unchanged, when the impact force generated by the falling mineral material is transmitted to the support rod 603 through the contact component 2, the support rod 603 drives the radial piston head 605 to move along the radial direction, squeezing the oil, and the oil transmits the squeezing force to the axial piston head 608. The axial piston head 608 will move outward along the axial direction and be transmitted to the inner contact seat 606 through the moving rod 607. The position of the inner contact seat 606 will squeeze the pressure spring 407, and the pressure spring 407 will be compressed and deformed, which has a buffering effect. As a result, this buffering effect can be utilized to prevent the impact force of the mineral material from directly acting on the rollers and the conveyor belt, thereby preventing the rollers and the conveyor belt from being damaged; this buffering force can be adjusted, specifically: rotating the adjusting screw 405, the adjusting screw 405 drives the outer contact seat 406 to move inward along the axial direction under the action of the thread, squeezing the pressure spring 407, the deformation of the pressure spring 407 increases, and the elastic force of the pressure spring 407 increases, thereby increasing the threshold value of the buffering deformation of the pressure spring 407; conversely, the deformation of the pressure spring 407 can also be reduced, reducing the threshold value of the buffering deformation of the pressure spring 407, which is suitable for the delivery of less mineral material.

[0059] Working principle: When installing the roller, the rotating shaft 401 is installed on the conveying equipment of the mine. When the ore is dropped, the impact force generated by the falling ore is transmitted to the support rod 603 through the contact component 2. The support rod 603 drives the radial piston head 605 to move along the radial direction, squeezing the oil. The oil transmits the squeezing force to the axial piston head 608. The axial piston head 608 moves outward along the axial direction and is transmitted to the inner contact seat 606 through the moving rod 607. The position of the inner contact seat 606 squeezes the pressure spring 407, and the pressure spring 407 is compressed and deformed, which has a buffering effect. By utilizing this buffering effect, the impact force of the ore can be prevented from directly acting on the roller and the conveyor belt, thereby preventing the roller and the conveyor belt from being damaged.

[0060] When the long arm 201 rotates clockwise, since there is air in the recoverable airbag 306, it cannot provide rigid support before the air inside it is completely discharged. Because there is air in the recoverable airbag 306, when the contact wheel 305 is compressed, the extrusion force can be transmitted to the recoverable airbag 306. The recoverable airbag 306 is compressed and the gas inside is blown out from the air outlet of the air pipe 303. Since the air outlet is small, it takes a certain amount of time for the gas to be released. This feature can provide a buffering effect for the long arm 201. When the gas in the recoverable airbag 306 is completely discharged, the contact wheel 305 and the movable seat 304 can provide rigid support for the long arm 201, ensuring that the long arm 201 is well stressed.

[0061] When there is no need to convey mineral materials, the adjusting screw 405 is rotated. Under the action of the thread, the adjusting screw 405 drives the outer contact seat 406 to move inward along the axial direction, squeezing the pressure spring 407. The deformation of the pressure spring 407 increases, and the elastic force of the pressure spring 407 increases, thereby increasing the threshold value of the buffering deformation of the pressure spring 407. Since the conveyor belt lacks the downward pressure of the mineral materials, the conveyor belt will be pushed upward by the short arm 204 and the short contact pad 205. The conveyor belt is high in the middle and low on both sides. Therefore, the conveyor belt is in an inclined state, which can prevent rainwater and impurities from falling on it. At this time, the upward part 203 rotates with the long arm 201. The upward part 203 will provide support for the conveyor belt, ensuring the stability of the conveyor belt and meeting the complex use environment of the mine.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
