[0002] In the field of mineral transportation and detection, it is usually necessary to use a conveyor to transport the minerals, and during the transportation process, it is necessary to use a pressure roller to flatten the minerals to make the mineral flow smooth, so as to improve the density, stability and flatness of the minerals. However, the pressure rollers in the relevant technology are usually made of metal, which are easy to stick to mineral blocks during the mineral shaping process, affecting the flattening effect of the pressure roller on the mineral, which is not conducive to the flatness of the mineral. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a pressure roller, a mineral shaping component and a mineral detection device for mineral shaping, which can solve the problem in the related art that the pressure roller is more likely to stick to mineral blocks during the mineral shaping process.

[0004] In a first aspect, an embodiment of the present application provides a pressure roller for mineral shaping, comprising a roller body and a sleeve, wherein the sleeve is sleeved on the outside of the roller body, and the roller body and the sleeve cooperate in the circumferential upper limit position of the roller body, and the sleeve is an anti-sticking structure.

[0005] In the embodiment of the present application, a sleeve is provided on the outside of the roller body of the pressure roller. Since the roller body and the sleeve are matched in the circumferential upper limit position of the roller, the sleeve rotates with the roller body, and the sleeve directly contacts the mineral. Since the sleeve adopts an anti-sticking structure, the binding energy of the sleeve is low, which can prevent the sleeve from sticking to mineral blocks during the mineral shaping process, avoid affecting the flattening effect of the mineral, and ensure the flatness of the mineral.

[0006] Optionally, the sleeve is an ultra-high molecular weight polyethylene structure.

[0007] With this arrangement, the ultra-high molecular weight polyethylene has a lower binding energy and has excellent impact resistance, wear resistance, lubrication performance and low temperature performance, which is more conducive to preventing the sleeve from adhering to mineral blocks and is conducive to improving the flattening effect of the pressure roller on the mineral.

[0008] Optionally, the roller shaft body includes a connected intermediate shaft segment and an edge shaft segment, the sleeve is sleeved on the outside of the intermediate shaft segment, and the intermediate shaft segment and the sleeve cooperate in the circumferential upper limit position of the roller shaft body, and the edge shaft segment is provided with a limiting protrusion, and the limiting protrusion cooperates with the sleeve in the axial upper limit position of the intermediate shaft segment.

[0009] With such arrangement, the axial position of the sleeve is limited by the limiting protrusion, thereby further preventing the sleeve from axially moving relative to the roller body, and being more conducive to relative fixation of the sleeve and the roller body.

[0010] Optionally, the edge shaft segment includes a first edge shaft segment and a second edge shaft segment, the first edge shaft segment and the second edge shaft segment are respectively located at two ends of the middle shaft segment, and at least one of the first edge shaft segment and the second edge shaft segment is detachably connected to the middle shaft segment.

[0011] With such arrangement, the edge shaft segment and the middle shaft segment are connected in a detachable manner, which facilitates the disassembly of at least one of the first edge shaft segment and the second edge shaft segment. The sleeve loses the limiting effect of the limiting protrusion, and the sleeve can be detached from the middle shaft segment along the axial direction of the middle shaft segment to replace the sleeve, which is beneficial to extending the service life of the pressure roller.

[0012] Optionally, the limiting protrusion of the edge shaft segment is provided with a connecting hole, and the end of the intermediate shaft segment is provided with a first threaded hole, and the pressure roller also includes a first fastener, which passes through the connecting hole and extends into the first threaded hole to connect the edge shaft segment and the intermediate shaft segment, and the limiting protrusion of the edge shaft segment is also provided with a second threaded hole, and the pressure roller also includes a second fastener, which is threadedly matched with the second threaded hole, and the end of the second fastener abuts against the end of the intermediate shaft segment, and when the first fastener is detached from the connecting hole and the first threaded hole, the end of the second fastener abuts against the intermediate shaft segment by screwing the second fastener to separate the edge shaft segment and the intermediate shaft segment.

[0013] In this way, on the basis of the detachable connection between the edge shaft segment and the middle shaft segment through the first fastener, a second threaded hole is added to the limiting protrusion of the edge shaft segment, and a supporting force can be applied to the middle shaft segment through the second fastener to separate the edge shaft segment and the middle shaft segment, which is more conducive to the disassembly of the edge shaft segment.

[0014] Optionally, a first limiting groove is provided on the wall surface of the intermediate shaft segment, and a second limiting groove is provided on the inner wall surface of the sleeve, and the first limiting groove and the second limiting groove respectively extend along the axial direction of the intermediate shaft segment, and the pressure roller also includes a limiting member, a part of the limiting member extends into the first limiting groove, and a second part of the limiting member extends into the second limiting groove, so that the sleeve and the intermediate shaft segment are relatively fixed in the circumferential direction of the roller shaft body.

[0015] With such arrangement, the limiting member cooperates with the intermediate shaft section and the sleeve respectively to achieve circumferential upper limit cooperation of the intermediate shaft section and the sleeve. Moreover, the limiting member can be separated from the first limiting groove and the second limiting groove, thereby facilitating the removal of the sleeve for replacement.

[0016] Optionally, in at least one direction of the circumference and axial direction of the intermediate shaft segment, multiple first limit grooves are arranged at intervals, and in at least one direction of the circumference and axial direction of the sleeve, multiple second limit grooves are arranged at intervals, the number of the limit members is multiple, and the first limit grooves, the second limit grooves and the limit members correspond to each other one by one.

[0017] With such an arrangement, the number of the first limit grooves and the second limit grooves increases, and the number of limit members also increases, which is beneficial for limiting different positions of the sleeve and different positions of the intermediate shaft segment through more limit members, and is more beneficial for fixing the sleeve as a whole relative to the intermediate shaft segment in the circumferential direction of the intermediate shaft segment, thereby improving the limit stability.

[0018] Optionally, a positioning protrusion is provided at the end of one of the intermediate shaft segment and the edge shaft segment, and a positioning groove is provided at the other end, the positioning protrusion extends into the positioning groove, and the positioning protrusion is positioned and matched with the positioning groove.

[0019] With such arrangement, before the middle shaft segment and the edge shaft segment are connected, the middle shaft segment and the edge shaft segment are positioned in advance through the positioning cooperation of the positioning protrusion and the positioning groove, which is more conducive to accurately connecting the middle shaft segment and the edge shaft segment.

[0020] In a second aspect, an embodiment of the present application further provides a mineral shaping assembly, comprising a cover plate and the above-mentioned pressing roller, wherein the cover plate is provided with an opening, and the end of the roller body extends into the opening.

[0021] In this way, the pressure roller of the mineral shaping component is additionally provided with a sleeve with an anti-sticking effect. The sleeve has a low binding energy, which can prevent the sleeve from sticking to mineral blocks during the mineral shaping process, avoid affecting the flattening effect on the mineral, and ensure the flatness of the mineral.

[0022] Optionally, the mineral shaping component further comprises a scraper, the scraper is rotatably disposed on the cover plate, the scraper is in contact with the outer wall surface of the sleeve, and the scraper is a flexible structure.

[0023] In this configuration, the mineral shaping assembly is equipped with a scraper, and during the roller mineral shaping process, the scraper is used to scrape off the mineral blocks adhered to the sleeve surface to prevent the mineral blocks from continuing to adhere and affecting the roller's flattening effect on the mineral. In addition, the scraper adopts a flexible structure to prevent the scraper from damaging the sleeve.

[0024] Optionally, the mineral shaping assembly further comprises an elastic member, one end of which is connected to the cover plate, and the other end of which is connected to the scraper, and when the scraper is in contact with the outer wall surface of the sleeve, the elastic member is in an elastic deformation state.

[0025] With such arrangement, by adding an elastic member, the elastic force of the elastic member is utilized to keep the scraper in continuous contact with the outer wall of the sleeve, so that the scraper can exert a scraping force on the sleeve, which is more conducive to the scraper to smoothly scrape away the mineral blocks adhered to the surface of the sleeve.

[0026] Optionally, at least two of the scrapers and the pressure rollers are arranged at intervals, and the scrapers and the pressure rollers correspond to each other one by one.

The binding energy of the sleeve is low, which can prevent the sleeve from sticking to mineral blocks during the mineral shaping process, avoid affecting the flattening effect on the mineral, and ensure the flatness of the mineral.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0034] In the following, in combination with the accompanying drawings, the pressing roller, mineral shaping assembly and mineral detection device for mineral shaping provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0035] Please refer to Figure 1-Figure 9The pressure roller 10 disclosed in the embodiment of the present application is used for mineral shaping. The mineral can be coal or other minerals other than coal. The embodiment of the present application does not specify the specific type of the mineral. The pressure roller 10 includes a roller body 100 and a sleeve 200, wherein the roller body 100 is the main component of the pressure roller 10, and the sleeve 200 is sleeved on the outside of the roller body 100. The roller body 100 and the sleeve 200 are matched in the circumferential upper limit of the roller body 100, so the sleeve 200 can rotate with the roller body 100. During the rotation of the pressure roller 10, the outer wall of the sleeve 200 is in direct contact with the mineral.

[0036] Optionally, the roller body 100 may be a cylindrical structure, the sleeve 200 may be an annular structure, the roller body 100 may be a metal structure, and the roller body 100 and the sleeve 200 may be fixedly connected by cold pressing, welding and other techniques, thereby being fitted in the circumferential limit direction of the roller body 100.

[0037] The sleeve 200 is an anti-sticking structure. Specifically, during the mineral shaping process, the anti-sticking structure has a low binding energy, which can prevent the mineral blocks from sticking to the outer wall surface of the sleeve 200, avoid affecting the flattening effect of the mineral, and ensure the flatness of the mineral.

[0038] Optionally, the sleeve 200 is an ultra-high molecular weight polyethylene structure. Specifically, ultra-high molecular weight polyethylene is a thermoplastic engineering plastic with a linear structure and excellent comprehensive performance. It has low binding energy and excellent impact resistance, wear resistance, lubrication performance and low temperature performance. It is more conducive to preventing the sleeve 200 from adhering to mineral blocks and is conducive to improving the flattening effect of the pressure roller 10 on the mineral. Of course, the sleeve 200 can also adopt other structures with lower binding energy as long as it can play an anti-sticking effect. The embodiment of the present application does not limit the specific material of the sleeve 200.

[0039] In an alternative embodiment, reference Figure 2 As shown, the roller body 100 includes a connected middle shaft section 120 and an edge shaft section 110, the axis of the middle shaft section 120 and the axis of the edge shaft section 110 are colinear, the middle shaft section 120 is located in the middle position of the roller body 100, and the edge shaft section 110 is located at the edge position of the roller body 100. Optionally, the middle shaft section 120 and the edge shaft section 110 can be a split structure or an integrated structure. The sleeve 200 is sleeved on the outside of the middle shaft section 120, that is, the sleeve 200 is located in the middle position of the roller body 100, and the middle shaft section 120 and the sleeve 200 are matched in the circumferential limit direction of the roller body 100. Optionally, the inner diameter of the sleeve 200 is smaller than the maximum diameter of the middle shaft section 120. The middle shaft section 120 and the sleeve 200 can be fixedly connected by cold pressing, welding and other technologies, so as to achieve limited matching in the circumferential direction of the roller body 100.

[0040] refer to Figure 1-Figure 3 As shown, the edge shaft segment 110 is provided with a limiting protrusion 110a, and the limiting protrusion 110a cooperates with the sleeve 200 in the axial upper limit position of the middle shaft segment 120. Optionally, the limiting protrusion 110a contacts the sleeve 200 in the axial upper limit position of the middle shaft segment 120; the direction of the limiting protrusion 110a and the sleeve 200 is the direction from the edge shaft segment 110 to the middle shaft segment 120, and the direction is parallel to the axial direction of the middle shaft segment 120. Optionally, the limiting protrusion 110a can be a block-shaped protrusion, a strip-shaped protrusion, etc., and the embodiment of the present application does not limit the specific structure of the limiting protrusion 110a.

[0041] In this embodiment, the axial position of the sleeve 200 is limited by the limiting protrusion 110a, which further prevents the sleeve 200 from axially moving relative to the roller body 100, and is more conducive to relative fixation of the sleeve 200 and the roller body 100.

[0042] Further optionally, the limiting protrusion 110a can be an annular protrusion, which surrounds the edge shaft segment 110 and extends along the circumference of the edge shaft segment 110. In this way, on the circumference of the edge shaft segment 110, different positions of the limiting protrusion 110a respectively cooperate with different positions of the sleeve 200, and the area of ​​the limiting cooperation is increased, which is more conducive to fixing the sleeve 200 relative to the roller body 100.

[0043] Of course, in other embodiments, the edge shaft segment 110 may not be provided with the limiting protrusion 110 a , and the middle shaft segment 120 may be fixedly connected to the sleeve 200 so that the sleeve 200 is fixed relative to the roller body 100 .

[0044] In an alternative embodiment, reference Figure 1-Figure 3 As shown, the edge shaft segment 110 includes a first edge shaft segment 111 and a second edge shaft segment 112, and the first edge shaft segment 111 and the second edge shaft segment 112 are respectively located at two ends of the middle shaft segment 120, and the first edge shaft segment 111 and the second edge shaft segment 112 are both provided with a limiting protrusion 110a, and the limiting protrusion 110a of the first edge shaft segment 111 cooperates with the sleeve 200 in the first direction, and the first direction is the direction from the first edge shaft segment 111 to the sleeve 200, and the limiting protrusion 110a of the second edge shaft segment 112 cooperates with the sleeve 200 in the second direction, and the second direction is the direction from the second edge shaft segment 112 to the sleeve 200, and the first direction is opposite to the second direction, and the first direction and the second direction are respectively parallel to the axial direction of the middle shaft segment 120.

[0045] Optionally, the structures and shapes of the first edge shaft segment 111 and the second edge shaft segment 112 may be the same or different.

[0046] In this embodiment, the first edge shaft segment 111 and the second edge shaft segment 112 support the middle shaft segment 120 from both ends respectively, and both are respectively provided with corresponding limiting protrusions 110a to cooperate with the sleeve 200 for limiting the sleeve 200, so that the sleeve 200 can be limited from different directions, which is more conducive to fixing the sleeve 200 relative to the roller body 100.

[0047] In an optional embodiment, the first edge shaft segment 111 and the second edge shaft segment 112 are respectively fixedly connected to the middle shaft segment 120 by welding, cold pressing or other techniques.

[0048] In another embodiment, at least one of the first edge shaft segment 111 and the second edge shaft segment 112 is detachably connected to the middle shaft segment 120. That is, only one of the first edge shaft segment 111 and the second edge shaft segment 112 may be detachably connected to the middle shaft segment 120, or the first edge shaft segment 111 and the second edge shaft segment 112 may be detachably connected to the middle shaft segment 120. Optionally, at least one of the first edge shaft segment 111 and the second edge shaft segment 112 may be detachably connected to the middle shaft segment 120 by bolt connection, clamping, etc., and the embodiment of the present application does not limit the connection method between the edge shaft segment 110 and the middle shaft segment 120.

[0049] With this embodiment, the edge shaft segment 110 and the middle shaft segment 120 are connected in a detachable manner, which facilitates the disassembly of at least one of the first edge shaft segment 111 and the second edge shaft segment 112. The sleeve 200 loses the limiting effect of the limiting protrusion 110a, and then the sleeve 200 can be detached from the middle shaft segment 120 along the axial direction of the middle shaft segment 120 to replace the sleeve 200, which is beneficial to extending the service life of the pressure roller 10.

[0050] In an alternative embodiment, reference Figure 1-Figure 3 As shown, the limiting protrusion 110a of the edge shaft segment 110 is provided with a connecting hole 110b, and the connecting hole 110b is a through hole. The end of the intermediate shaft segment 120 is provided with a first threaded hole 121. Optionally, the connecting hole 110b is opened along the axial direction of the edge shaft segment 110, and the first threaded hole 121 is opened along the circumferential direction of the intermediate shaft segment 120; the pressure roller 10 also includes a first fastener, which can be a connecting piece with external threads such as a screw or a bolt. The first fastener passes through the connecting hole 110b and extends into the first threaded hole 121 to connect the edge shaft segment 110 and the intermediate shaft segment 120.

[0051] With such arrangement, when the first fastener is screwed in and the first fastener passes through the connecting hole 110b in sequence and extends into the first threaded hole 121, the edge shaft segment 110 and the middle shaft segment 120 are relatively fixed, and the limiting protrusion 110a axially limits the sleeve 200 to prevent the sleeve 200 from being separated from the middle shaft segment 120; when the first fastener is screwed in the opposite direction and the first fastener is separated from the first threaded hole 121, the edge shaft segment 110 and the middle shaft segment 120 are separable, the edge shaft segment 110 can be disassembled, the sleeve 200 loses the limiting effect of the limiting protrusion 110a of the edge shaft segment 110, and the sleeve 200 can be separated from the middle shaft segment 120 for disassembly.

[0052] Optionally, the limiting protrusion 110a of the edge shaft segment 110 is provided with a plurality of connection holes 110b at intervals along the circumference of the edge shaft segment 110, and the middle shaft segment 120 is provided with a plurality of first threaded holes 121 at intervals along its own circumference, and the number of first fasteners is also multiple, and the connection holes 110b, the first threaded holes 121 and the first fasteners correspond to each other one by one. In this way, different positions of the edge shaft segment 110 and the middle shaft segment 120 are connected respectively by a plurality of first fasteners, which is conducive to increasing the connection area between the edge shaft segment 110 and the middle shaft segment 120 and improving the connection stability between the edge shaft segment 110 and the middle shaft segment 120.

[0053] Further optionally, the limiting protrusion 110a of the first edge shaft segment 111 and the limiting protrusion 110a of the second edge shaft segment 112 are respectively provided with a plurality of connecting holes 110b at intervals along their own circumferences, and a plurality of first threaded holes 121 are respectively provided at both ends of the intermediate shaft segment 120 at intervals along their own circumferences.

[0054] In a further embodiment, reference Figure 2 As shown, the limiting protrusion 110a of the edge shaft segment 110 is further provided with a second threaded hole 110c, and the pressure roller 10 further includes a second fastener, which can be a connecting member with external threads such as a screw or a bolt, and the second fastener is threadedly matched with the second threaded hole 110c, and the end of the second fastener abuts against the end of the middle shaft segment 120. Specifically, when the first fastener is separated from the connecting hole 110b and the first threaded hole 121, that is, when the first fastener is not connected to the edge shaft segment 110 and the middle shaft segment 120, due to a certain extrusion force between the edge shaft segment 110 and the middle shaft segment 120, the two cannot be directly separated, and by screwing the second fastener, the end of the second fastener abuts against the middle shaft segment 120, so as to separate the edge shaft segment 110 and the middle shaft segment 120.

[0055] Optionally, the second threaded hole 110 c is opened along the axial direction of the edge shaft segment 110 , and the second fastener passes through the second threaded hole 110 c to abut against the end of the middle shaft segment 120 .

[0056] In this embodiment, the limiting protrusion 110a of the edge shaft segment 110 is additionally provided with a second threaded hole 110c, and a second fastener can be used to apply abutting force to the middle shaft segment 120 to separate the edge shaft segment 110 and the middle shaft segment 120, which is more conducive to disassembling the edge shaft segment 110.

[0057] Of course, in other embodiments, the edge shaft segment 110 may not be provided with the second threaded hole 110c, and the edge shaft segment 110 and the middle shaft segment 120 are connected and separated only by the first fastener.

[0058] In an optional embodiment, the limiting protrusion 110a of the edge shaft segment 110 is provided with a plurality of second threaded holes 110c at intervals along the circumference of the edge shaft segment 110, and the number of the second fasteners is multiple, and the second threaded holes 110c correspond to the second fasteners one by one. In this way, the limiting protrusion 110a of the edge shaft segment 110 is provided with a plurality of second threaded holes 110c, and it is possible to apply abutting forces to different positions of the intermediate shaft segment 120 through the plurality of second fasteners in the circumference of the intermediate shaft segment 120, which is more conducive to separating the edge shaft segment 110 and the intermediate shaft segment 120, and further facilitates the disassembly of the edge shaft segment 110. Optionally, the limiting protrusion 110a of the first edge shaft segment 111 and the limiting protrusion 110a of the second edge shaft segment 112 are respectively provided with a plurality of second threaded holes 110c at intervals along their own circumferences.

[0059] In a further embodiment, reference Figure 2 As shown, in the circumferential direction of the edge shaft segment 110, the connecting holes 110b and the second threaded holes 110c are alternately distributed, that is, a second threaded hole 110c is arranged between two adjacent connecting holes 110b, and a connecting hole 110b is arranged between two adjacent second threaded holes 110c.

[0060] With such arrangement, the second threaded holes 110c and the connecting holes 110b are respectively distributed relatively evenly in the circumferential direction of the edge shaft segment 110, and the connection between the edge shaft segment 110 and the intermediate shaft segment 120 is relatively evenly distributed, which is beneficial for connecting the entire edge shaft segment 110 through multiple first fasteners and improving the connection stability; moreover, the force application positions of the multiple second fasteners to the intermediate shaft segment 120 are also relatively evenly distributed, which is more beneficial for separating the intermediate shaft segment 120 and the edge shaft segment 110.

[0061] In the scheme of this application, reference is made to Figure 3As shown, the wall surface of the intermediate shaft section 120 is provided with a first limiting groove 122, and the inner wall surface of the sleeve 200 is provided with a second limiting groove 210, and the first limiting groove 122 and the second limiting groove 210 extend along the axial direction of the intermediate shaft section 120 respectively. The pressure roller 10 also includes a limiting member, a part of the limiting member extends into the first limiting groove 122, and a second part of the limiting member extends into the second limiting groove 210, so that the sleeve 200 and the intermediate shaft section 120 are matched in the circumferential upper limit position of the intermediate shaft section 120. The limiting member can be a limiting block, a limiting strip or other structures, and the embodiment of the present application does not limit the specific structure of the limiting member.

[0062] Optionally, the first limiting groove 122 and the second limiting groove 210 can be square grooves or arc-shaped grooves. The embodiment of the present application does not limit the shapes of the first limiting groove 122 and the second limiting groove 210. The groove wall surface of the first limiting groove 122 and the groove wall surface of the second limiting groove 210 respectively cooperate with the surface of the limiting member.

[0063] By adopting this embodiment, the limiting member cooperates with the intermediate shaft segment 120 and the sleeve 200 respectively to achieve the circumferential upper limit cooperation of the intermediate shaft segment 120 and the sleeve 200 in the intermediate shaft segment 120, and the limiting member can be separated from the first limiting groove 122 and the second limiting groove 210, thereby facilitating the disassembly of the sleeve 200 for replacement.

[0064] Optionally, the first limiting groove 122, the second limiting groove 210 and the limiting member are all strip structures, and the first limiting groove 122, the second limiting groove 210 and the limiting member extend along the axial direction of the intermediate shaft segment 120. Further optionally, the limiting member can be a cylindrical pin or other limiting member. With such a configuration, along the axial direction of the intermediate shaft segment 120, the limiting member respectively cooperates with different positions of the intermediate shaft segment 120 and the sleeve 200, which is more conducive to fixing the entire sleeve 200 relative to the intermediate shaft segment 120 in the circumferential direction of the intermediate shaft segment 120, and preventing the sleeve 200 from rotating relative to the intermediate shaft segment 120.

[0068] By adopting this embodiment, the number of the first limiting grooves 122 and the second limiting grooves 210 increases, and the number of limiting members also increases, which is beneficial for limiting different positions of the sleeve 200 and different positions of the intermediate shaft segment 120 through more limiting members, and is more beneficial for fixing the sleeve 200 as a whole relative to the intermediate shaft segment 120 in the circumferential direction of the intermediate shaft segment 120, thereby improving the limiting stability.

Further, optionally, the first edge shaft segment 111 and the second edge shaft segment 112 are both sleeved with bearings 71.

[0074] In a further embodiment, at least two rollers 10 are arranged at intervals along the conveying direction of the conveyor 70, and two adjacent rollers 10 are connected in transmission.

Further optionally, the first ends of two adjacent rollers 10 and the second ends of two adjacent rollers 10 are connected in transmission through a chain 72, respectively.

[0075] Based on the pressure roller 10 disclosed in the present application, the present application embodiment also discloses a mineral shaping component, referring to Figure 5-Figure 7 As shown, the mineral shaping assembly includes a cover plate 20 and the pressure roller 10 in the above embodiment, the cover plate 20 is provided with an opening 20a, and the end of the roller body 100 extends into the opening 20a. Specifically, when the pressure roller 10 is installed on the conveyor 70, the cover plate 20 covers the side of the pressure roller 10 facing away from the conveyor 70, and at the same time, the end of the roller body 100 extends into the opening 20a. Optionally, the cover plate 20 is provided with a plurality of openings 20a at intervals, and the end of the first edge shaft segment 111 and the end of the second edge shaft segment 112 respectively extend into different openings 20a.

[0076] In this embodiment, the pressing roller 10 of the mineral shaping component is additionally provided with a sleeve 200 with an anti-sticking effect.

[0077] In an alternative embodiment, reference Figure 8 As shown, the mineral shaping assembly further includes a scraper 30, which is rotatably disposed on the cover plate 20, and the scraper 30 contacts the outer wall surface of the sleeve 200. The scraper 30 is a flexible structure, and the scraper 30 can be made of a flexible material such as polyurethane, rubber, etc. Optionally, the mineral shaping assembly further includes a rotating shaft 50, which is disposed on the cover plate 20, and the scraper 30 is provided with an axial hole, and the rotating shaft 50 passes through the axial hole, and the rotating shaft 50 is rotatably matched with the axial hole to realize the rotatable connection between the scraper 30 and the cover plate 20.

[0078] Further optionally, reference Figure 7-Figure 9 As shown, the mineral shaping assembly further includes a scraper bracket 60, which is used to support the scraper 30. The cover plate 20 is provided with a support plate 21. The scraper bracket 60 is rotatably arranged on the support plate 21 through a rotating shaft 50, and the scraper 30 is connected to the scraper bracket 60. The scraper 30 and the scraper bracket 60 can be detachably connected by bolt connection, clamping, etc., so that the scraper 30 can be easily disassembled and replaced.

[0079] In this embodiment, the mineral shaping assembly is additionally provided with a scraper 30. During the mineral shaping process of the pressing roller 10, the scraper 30 is used to scrape off the mineral blocks adhered to the surface of the sleeve 200, so as to prevent the mineral blocks from continuing to adhere and affecting the flattening effect of the pressing roller 10 on the mineral. Moreover, the scraper 30 adopts a flexible structure to prevent the scraper 30 from damaging the sleeve 200.

[0080] Of course, in other embodiments, the mineral shaping assembly may not be provided with the scraper 30, that is, the scraper 30 is not used to scrape off the mineral blocks adhered to the sleeve 200 during the mineral shaping process.

[0081] In an alternative embodiment, reference Figure 8 As shown, the mineral shaping assembly also includes an elastic member 40, which can be but is not limited to a spring. One end of the elastic member 40 is connected to the cover plate 20, and the other end of the elastic member 40 is connected to the scraper 30. When the scraper 30 contacts the outer wall of the sleeve 200, the elastic member 40 is in an elastic deformation state.

[0082] Optionally, one end of the elastic member 40 can be fixedly connected to the cover plate 20 by welding, bonding, etc., and the other end of the elastic member 40 can be fixedly connected to the scraper 30 by welding, bonding, etc. Further, optionally, one end of the elastic member 40 is connected to the support plate 21 of the cover plate 20.

[0083] According to the present embodiment, an elastic member 40 is added and the elastic force of the elastic member 40 is utilized to keep the scraper 30 in continuous contact with the outer wall of the sleeve 200 , so that the scraper 30 can exert a scraping force on the sleeve 200 , which is more conducive to the scraper 30 to smoothly scrape away the mineral blocks adhered to the surface of the sleeve 200 .

[0084] In a further embodiment, the number of elastic members 40 is at least two, and along the direction of the rotation axis of the scraper 30, the two elastic members 40 are respectively located at the two ends of the scraper 30, that is, the two elastic members 40 are respectively located at the two ends of the rotating shaft 50.

[0085] With this embodiment, the number of elastic members 40 is increased, and at least two elastic members 40 provide elastic force to the scraper 30 from both ends respectively, which is more conducive to the overall structure of the scraper 30 to stably apply a scraping force to the outer wall surface of the sleeve 200, thereby improving the scraping effect of the scraper 30, and further helping to improve the flattening effect of the sleeve 200 on the mineral.

[0086] In an optional embodiment, the number of the pressure roller 10 and the number of the scraper 30 are both one.

[0087] In another embodiment, reference Figure 5-Figure 6 as well as Fig. 9 As shown, at least two pressure rollers 10 and scrapers 30 are arranged at intervals, and the pressure rollers 10 and scrapers 30 correspond to each other one by one.

[0088] By adopting this embodiment, the number of pressing rollers 10 is increased, and the mineral shaping carbon is rolled simultaneously by at least two pressing rollers 10. Moreover, the number of scrapers 30 is also increased. The sleeve 200 of each pressing roller 10 is scraped by the corresponding scraper 30 to scrape off the adhered mineral blocks, which is more conducive to improving the flattening effect of the mineral.

[0089] Based on the mineral shaping component disclosed in the present application, the embodiment of the present application also discloses a mineral detection device, and the mineral detection device includes the mineral shaping component in the above embodiment. Optionally, the mineral detection device adopts an online integrated mineral sampling component detection. In one embodiment, the mineral detection device includes an online detection sample preparation system, which is mainly composed of: a belt and a mineral shaping component in the present application, and the mineral shaping component includes a shaping plate and a pressure roller 10 in the present application. The shaping plate shapes the mineral and sends it to the pressure roller 10, and the pressure roller 10 further flattens the mineral. The mineral passes through the spectral acquisition subsystem to collect the spectral data of the mineral, and the collected spectral data is transmitted to the signal processing subsystem for spectral data processing. The processed spectral data is sent to the analysis subsystem to complete the mineral composition detection.

[0090] For example, if the spectral data includes near-infrared spectral signals and X-ray fluorescence spectral signals, the signal processing subsystem processes the near-infrared spectral signals and X-ray fluorescence spectral signals in the spectral data to obtain target spectral data; the analysis subsystem performs analysis of the target spectral data based on the mineral detection model to obtain multiple components in the mineral, such as one or more of the ash composition, ash content, volatile matter, carbon and hydrogen, ash melting point, total water, total sulfur and calorific value in coal.

[0091] Specifically, X-rays are particle streams generated by the transition of electrons in atoms between two energy levels with a large energy difference. They are electromagnetic radiation with a wavelength between ultraviolet rays and gamma rays. X-rays have a shorter wavelength, between 0.01nm-100nm, and a frequency range of 30PHz-30EHz; near-infrared light is an electromagnetic wave between visible light and mid-infrared light, with a wavelength in the range of 780nm-2526nm.

[0092] In other embodiments, the spectral data may include one or more other spectral signals in addition to near-infrared spectral signals and X-ray fluorescence spectral signals, such as microwave spectroscopy, LIBS (Laser-Induced Breakdown Spectroscopy) spectroscopy, etc. The microwaves used in microwave spectroscopy refer to electromagnetic waves with a frequency of 300MHz-300GHz and a wavelength of 1m (excluding 1m)-1mm; LIBS forms plasma by focusing ultrashort pulse lasers on the sample surface, and uses a spectrometer to analyze the plasma emission spectrum to identify the elemental composition in the mineral, thereby enabling the identification, classification, qualitative and quantitative analysis of the mineral.

[0093] With such arrangement, during the mineral shaping process, the pressure roller 10 used in the mineral detection device is additionally provided with a sleeve 200 with an anti-sticking effect. The sleeve 200 has a low binding energy, which can prevent the sleeve 200 from sticking to mineral blocks during the mineral shaping process, thereby avoiding affecting the flattening effect on the mineral, ensuring the flatness of the mineral, and facilitating the effective detection of the subsequent mineral components.

[0094] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
