The appearances of "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

[0053] The application discloses a belt conveyor roller structure, which refers to Figures 1-15 , comprising:

[0054] The barrel body 2 is a one-piece tubular hollow structure, and the circumferential curved surface of the barrel body 2 is a working surface; the shaft heads 1 are two in number and are symmetrically arranged in the length direction of the barrel body 2, and grooves are also formed in the shaft heads 1; the shaft heads 1 are placed at the two ends of the barrel body 2 and are installed on the barrel body 2 by welding, and the grooves are in communication with the hollow structure of the barrel body 2 to form cavities; the welding of the shaft heads 1 and the barrel body 2 reduces the use of shafts and sleeves, so that the replacement of the sleeves due to damage of the sleeves in the working process is avoided, and economic losses of enterprises are reduced.

[0055] The shaft connecting rollers 3 are two in number and are used for connecting the shaft parts and the barrel parts, and the shaft connecting rollers 3 are one-piece structures; the reinforcing rib plates 4 are arranged in the barrel parts and are used for supporting the barrel parts; the barrel parts of the shaft connecting rollers 3 are welded to form the roller structures; the reinforcing rib plates 4 are arranged to support the barrel parts, so that the strength of the rollers is increased.

[0056] The belt conveyor 6 comprises at least two roller structures and further comprises: a conveyor 6 body connected with the roller structures, which is used for transporting articles by allowing the articles to fall on the conveying belt; a dynamic scraping unit 5 arranged on the conveyor 6 body and used for dynamically cleaning the non-working surface of the conveying belt during the working of the conveying belt; and a cleaning unit 7 fixedly installed on the conveyor 6 and used for cleaning the conveying belt in a non-working state; the dynamic scraping unit 5 is arranged to clean the non-working surface of the conveying belt, i.e., the return section (lower surface) of the belt, during the working of the conveying belt.

[0057] The dynamic scraping unit 5 comprises a connecting plate 51 mounted on the conveyor 6, a sleeve 52 and a connecting shaft 53 in sliding connection with the connecting plate 51, a scraper 55 fixedly connected with the sleeve 52 and the connecting shaft 53 respectively, and a connecting spring 54 sleeved on the connecting shaft 53 and used for connecting the connecting plate 51 and the scraper 55; the scraper 55 is triangular in shape and at least two guide grooves 56 are arranged on the scraper 55; when the conveyor 6 is installed, the connecting plate 51 can be arranged on the conveyor 6, the installation position of the connecting plate 51 is adjusted, the connecting spring 54 is in a deformed state, the scraper 55 can be in contact with the conveying belt, the scraper 55 can be in contact with the surface of the belt during the movement of the belt, and the stains attached to the surface of the belt can be scraped, and the scraped stains can move along the guide grooves 56, thereby moving away from the conveying belt, and the cleaning work of the conveying belt is completed.

[0058] The cleaning unit 7 comprises flattening assemblies 71, scraping assemblies 72, detection assemblies 73 and rejection assemblies 74 arranged on the conveyor 6 in sequence along the rotating direction of the conveying belt; the number of the flattening assemblies 71 is two, and the scraping assemblies 72, the detection assemblies 73 and the rejection assemblies 74 are located between the two flattening assemblies 71; the flattening assembly 71 comprises a flattening seat arranged on the conveyor 6, a first motor 711, a driving shaft 715 and a driven shaft 717 located on the flattening seat, a first gear 712 sleeved on the driving shaft 715, a second gear 713 arranged on the flattening seat and in meshing connection with the first gear 712, a third gear 714 connected with the driven shaft 717 and in meshing connection with the second gear 713, a plurality of first driving wheels 716 uniformly sleeved on the driving shaft 715, and a plurality of lifting members 718 arranged on the driven shaft 717; the output end of the first motor 711 is connected with the driving shaft 715; the lifting member 718 comprises a connecting seat 7181 fixedly installed on the flattening seat, a lifting cylinder 7182 in movable connection with the connecting seat 7181, a support 7183 in movable connection with the output end of the lifting cylinder 7182 and sleeved on the driven shaft 717, a fourth gear 7184 sleeved on the driven shaft 717 and located in the support 7183, a hollow shaft 7186 arranged in the support 7183, a fifth gear 7185 and a second driving wheel 7187 respectively sleeved on the hollow shaft 7186, and a laser detection device fixedly installed on the conveyor 6; the laser detection device generates laser and makes the laser pass through the hollow shaft 7186, so as to detect the position of the dirt on the belt; the fourth gear 7184 is in meshing connection with the fifth gear 7185;

[0059] When the belt needs to be cleaned, the rotation of the conveyor 6 is stopped at this time, and then the tensioning unit is adjusted so that the belt is in a relaxed state. Then, the lifting cylinder 7182 starts to work, and the moving lifting cylinder 7182 can drive the support 7183 to rotate around the driven shaft 717, and the moving support 7183 can drive the second driving wheel 7187 to rotate, so that the second driving wheel 7187 can contact with the belt. Then the first motor 711 starts to work, and the moving first motor 711 can drive the first gear 712 to rotate, thereby driving the second gear 713 and the third gear 714 to rotate, and the moving first gear 712 and the third gear 714 can drive the driving shaft 715 and the driven shaft 717 to rotate. The moving multifunctional shaft can drive the first driving wheel 716 to rotate, and at this time the belt is located between the two driving wheels. Then the rotation of the first driving wheel 716 and the second driving wheel 7187 can achieve the transportation and straightening of the belt.

[0060] During this process, the rotation speed and direction of the first motor 711 in the two smoothing assemblies 71 are different. Initially, the rotation direction of the first motor 711 is opposite, thereby completing the straightening of the belt. Then the rotation speed of the first motor 711 increases, thereby enabling the belt to move and avoiding large wrinkles in the belt, which can cause the failure of the stain removal work.

[0061] When the belt is relaxed, the contact pressure is adjusted by the cylinder, which can ensure the effective transportation of the driving wheel to the belt and will not damage the belt due to excessive pressure. In addition, the cooperation of the hollow shaft 7186 and the laser detection device enables the laser to pass through the hollow shaft 7186. When the laser receiving device cannot receive the signal, it means that the area needs to be removed.

[0062] The scraping assembly 72 comprises a rack 721 fixedly installed on the conveyor 6, a transmission motor 722 and a driving wheel 723 arranged on the rack 721, a transmission belt for connecting the output end of the transmission motor 722 and the driving wheel 723, a rotating rod 724 connected with the driving wheel 723, a rotating wheel 725 arranged at one end of the rotating rod 724, an adjusting rod 726 abutting with the rotating wheel 725 and movably connected with the rack 721, a scraping rod 728 arranged on the adjusting rod 726, and an elastic connecting piece 727 for connecting the rack 721 and the adjusting rod 726;

[0063] After the smoothing assembly 71 finishes the smoothing work on the belt, the transmission motor 722 starts to work at this time. The moving transmission motor 722 can drive the driving wheel 723 to rotate through the transmission belt arranged, and then the moving driving wheel 723 can drive the rotating rod 724 to move, and then the moving rotating rod 724 can drive the rotating wheel 725 to move. Through the contact between the rotating wheel 725 and the adjusting rod 726, the position of the scraping rod 728 is changed, so that the scraping rod 728 can contact with the belt to scrape off the stains on the belt to avoid that the belt is deformed too much due to long-term use, so that the dynamic scraping unit 5 cannot clean the surface of the belt when it works, thereby causing a large amount of dust to accumulate on the surface of the belt.

[0064] The detection assembly 73 comprises a frame fixedly installed on the conveyor 6, a bidirectional motor 731 fixedly installed on the frame, a rod body connected with the output end of the bidirectional motor 731, two swing arms 732 symmetrically arranged on the rod body, a first swing rod 733 and a second swing rod 734 movably connected with the swing arms 732, a limiting rod 735 fixedly installed on the frame, a first lifting plate 736 and a second lifting plate 737 arranged on the limiting rod 735, and a plurality of detection parts 75 arranged on the first lifting plate 736 and the second lifting plate 737 respectively; the detection part 75 comprises a connecting frame 751 connected with the first lifting plate 736, a first connecting rod 756 movably connected with the connecting frame 751, a movable frame 752 movably connected with the connecting frame 751, a first abutting wheel 753 connected with the movable frame 752, a third connecting rod 759 for connecting two first connecting rods 756 close to the first abutting wheel 753, a second abutting wheel 758 arranged on the other two first connecting rods 756, a second connecting rod 757 for connecting the first connecting rods 756 at different distances from the first abutting wheel 753, and a first spring 754 for connecting the movable frame 752 and the third connecting rod 759 and a second spring 755 for connecting the connecting frame 751 and the third connecting rod 759; two first swing rods 733 are connected with the first lifting plate 736 respectively, and two second swing rods 734 are arranged on the second lifting plate 737; at the same time, a visual detection device is arranged in the device, which can detect the protruding end on the belt, so as to detect the impurity area embedded in the belt; a connecting shaft 53 is arranged between the two first connecting rods 756 connected with the second abutting wheel 758 and the two first connecting rods 756 connected with the third connecting rod 759, and the connecting shaft 53 is located on the connecting frame 751;

[0065] When the impurity area on the belt needs to be positioned and detected, the bidirectional motor 731 starts to work at this time, the moving bidirectional motor 731 can drive the rod body to rotate, and then the moving rod body can drive the swing arm 732 to move, at this time the moving swing arm 732 can drive the first swing rod 733 and the second swing rod 734 to move, at this time the moving first swing rod 733 and the second swing rod 734 can drive the first lifting plate 736 and the second lifting plate 737 to move, at this time the first lifting plate 736 and the second lifting plate 737 can be brought close to each other or away from each other, at this time the detection part 75 can be close to the belt;

[0066] When the detection part 75 is close to the belt, when the detection part 75 encounters a protruding area (a dust area), at this time the first abutting wheel 753 can be lifted, and then the first abutting wheel 753 can change the deformation amount of the first spring 754 through the movable frame 752, and then the first spring 754 can drive the third connecting rod 759 to move, so as to drive one of the connecting shafts 53 to rotate, and then the moving connecting shaft 53 can make the second abutting wheel 758 move, at this time the first abutting wheel 753 is away from the belt, and the second abutting wheel 758 is close to the belt, so as to complete the stopping work of the belt or slow down the transmission speed of the belt, so as to ensure that the visual detection device can complete the detection work. When the direction belt is embedded with ore or other impurities, the rejection part 748 starts to work to complete the rejection work of the impurities embedded in the belt, otherwise if the belt is stopped because the dust is too thick, at this time the bidirectional motor 731 starts to work, so that the detection part 75 is away from the belt, and then the region is marked through the main control system, after the belt rotates for one turn, the dust is scraped off through the scraper 728, so as to avoid that the lower surface contacts with the roller during the belt working, so as to cause the dust at this place to be compacted, and increase the difficulty of dust cleaning.

[0067] The removing component 74 comprises a detection frame 741 mounted on the conveyor 6, at least two linear motion mechanisms 742 fixedly connected with the detection frame 741, driving blocks 743 arranged on the linear motion mechanisms 742, a slide rail 746 arranged on the detection frame 741, a driven block 744 in sliding connection with the slide rail 746, an inclined plate 745 arranged on the driven block 744, a lifting block 747 connected with the driven block 744, a rotating motor 7410 fixedly mounted on the lifting block 747, a rotating shaft 749 connected with the rotating motor 7410, and a plurality of removing parts 748 arranged on the rotating shaft 749; the front end of the driving block 743 is provided with a protrusion, and the protrusion is in abutment with the inclined plate 745; the removing part 748 comprises a mounting seat 7481 connected with the rotating shaft 749, support wheels 7482 symmetrically arranged on the mounting seat 7481, two moving air cylinders 7484 built-in the mounting seat 7481, adjusting blocks 7485 connected with the output ends of the moving air cylinders 7484, a plurality of movable rods 7486 in movable connection with the adjusting blocks 7485, a plurality of movable seats 7487 connected with the movable rods 7486, first support wheels 7482 in movable connection with the movable seats 7487, second support rods 7483 connected with the first support wheels 7482 and arranged on the mounting seat 7481, movable wheels 7489 located at the first support wheels 7482 and the second support wheels 7482, and reset springs 74810 for connecting the movable seats 7487 and the mounting seat 7481;

[0068] When the stripping assembly 74 needs to work, the linear motion mechanism 742 starts to work at this time, so that the driving block 743 can move on the inclined plate 745, thereby pushing the driven block 744 to move in the length direction of the slide rail 746, the moving driven block 744 can adjust the height of the lifting block 747, so that the stripping part 748 on the rotating shaft 749 can contact the surface of the belt, one of the stripping parts 748 contacts the upper surface of the belt, and the other contacts the lower surface. Then the moving cylinder 7484 in the lower stripping part 748 starts to work, the moving cylinder 7484 drives the adjusting block 7485 to work, the moving adjusting block 7485 drives the movable rod 7486 to move, so that the first supporting rod 7488 can be driven to move, thereby changing the angle between the first supporting rod 7488 and the second supporting rod 7483, lifting the belt to deform, exposing part of the ore embedded in the belt, and then rotating the other stripping part 748 through the rotating motor 7410, so that the movable wheel 7489 in the stripping part 748 can contact the ore, thereby completing the stripping work. The stripping work can strip the upper and lower surfaces of the belt; at the same time, by changing the angle between the first supporting rod 7488 and the second supporting rod 7483, the deformation amount of the belt can be increased (at this time, the smoothing assembly 71 needs to be matched to avoid excessive belt flattening), so that the embedded impurities can be exposed, and then contacted with the other stripping part 748, and the stripping work of the impurities is completed through the action of centrifugal force.

[0069] The moving cylinder 7484 in the stripping part 748 drives the adjusting block 7485, changes the angle of the first and second supporting rods 7483 through the movable rod 7486, can lift the belt to deform to expose the embedded ore, and can control the deformation amount of the belt by adjusting the angle - cooperate with the "non-complete flattening" state of the smoothing assembly 71, can forcibly expose the embedded impurities, solve the problem that the traditional stripping device is difficult to process deep impurities, realize synchronous processing of impurities on both sides of the belt, avoid the limitation of one-way cleaning, especially suitable for scenes where impurities may be on both sides or the position of embedded impurities is uncertain; at the same time, the device first deforms the belt through the angle adjustment of the supporting rod, forces the impurities to be exposed, and then generates centrifugal force through the rotating stripping part 748 to efficiently strip stubbornly attached impurities.

[0086]

[0087] The working principle is explained: when the installation work of the conveyor 6 is carried out, the connecting plate 51 can be arranged on the conveyor 6 at this time, the installation position of the connecting plate 51 is adjusted, the connecting spring 54 is in a deformed state, so that the scraper 55 can be in contact with the conveyor belt, and then in the process of belt movement, the scraper 55 can be in contact with the surface of the belt, and the stains attached to the surface of the belt can be scraped off, and the scraped stains can move along the guide groove 56, so as to move away from the conveyor belt, and complete the cleaning work of the conveyor belt;

[0088] When the belt needs to be cleaned, the rotation of the conveyor 6 is stopped, and then the tensioning unit is adjusted to make the belt in a relaxed state. Then the lifting cylinder 7182 starts to work, and the moving lifting cylinder 7182 can drive the support 7183 to rotate around the driven shaft 717. The moving support 7183 can drive the second driving wheel 7187 to rotate, so that the second driving wheel 7187 can contact with the belt. Then the first motor 711 starts to work, and the moving first motor 711 can drive the first gear 712 to rotate, so as to drive the second gear 713 and the third gear 714 to rotate. The moving first gear 712 and the third gear 714 can drive the driving shaft 715 and the driven shaft 717 to rotate, and the moving multifunctional shaft can drive the first driving wheel 716 to rotate. At this time, the belt is located between the two driving wheels. Then the rotation of the first driving wheel 716 and the second driving wheel 7187 can play a role in transporting and straightening the belt;

[0089] After the flattening assembly 71 completes the flattening work of the belt, the transmission motor 722 starts to work, and the moving transmission motor 722 can drive the driving wheel 723 to rotate through the transmission belt. Then the moving driving wheel 723 can drive the rotating rod 724 to move, and then the moving rotating rod 724 can drive the rotating wheel 725 to move. Through the contact between the rotating wheel 725 and the adjusting rod 726, the position of the scraping rod 728 is changed, so that the scraping rod 728 can contact with the belt to scrape off the stains on the belt;

[0090] When the impurity area on the belt needs to be positioned and detected, the bidirectional motor 731 starts to work at this time, and the moving bidirectional motor 731 can drive the rod body to rotate. Then the moving rod body can drive the swing arm 732 to move, and at this time the moving swing arm 732 can drive the first swing rod 733 and the second swing rod 734 to move. At this time, the moving first swing rod 733 and the second swing rod 734 can drive the first lifting plate 736 and the second lifting plate 737 to move, and at this time the first lifting plate 736 and the second lifting plate 737 can move close to each other or move away from each other, so that the detection part 75 can move close to the belt;

[0091] When the detection part 75 approaches the belt, when the detection part 75 encounters the convex region (the dust region), at this time, the first abutting wheel 753 can be lifted, then the first abutting wheel 753 can change the deformation amount of the first spring 754 through the movable frame 752, then the first spring 754 can drive the third connecting rod 759 to move, so that one of the connecting shafts 53 rotates, and then the moving connecting shaft 53 can drive the second abutting wheel 758 to move, at this time, the first abutting wheel 753 is away from the belt, and the second abutting wheel 758 approaches the belt, so that the belt stopping work or the belt transmission speed slowing down can be completed, so as to ensure that the visual detection device can complete the detection work;

[0092] When the rejection assembly 74 needs to work, at this time, the straight line movement mechanism 742 starts to work, so that the driving block 743 can move on the inclined plate 745, thereby pushing the driven block 744 to move in the length direction of the slide rail 746, the moving driven block 744 can adjust the height of the lifting block 747, so that the rejection part 748 on the rotating shaft 749 can contact the surface of the belt, one of the rejection parts 748 contacts the upper surface of the belt, and the other contacts the lower surface, then the moving cylinder 7484 in the lower rejection part 748 starts to work, the moving cylinder 7484 can drive the adjusting block 7485 to work, the moving adjusting block 7485 drives the movable rod 7486 to move, so as to drive the first supporting rod 7488 to move, so as to change the angle between the first supporting rod 7488 and the second supporting rod 7483, lift the belt to deform, expose part of the ore embedded in the belt, then drive the other rejection part 748 to rotate through the rotating motor 7410, so that the movable wheel 7489 in the rejection part 748 can contact the ore, so as to complete the rejection work, and the rejection work can reject the upper and lower surfaces of the belt; meanwhile, the angle between the first supporting rod 7488 and the second supporting rod 7483 can be changed to increase the deformation amount of the belt (at this time, the flattening assembly 71 needs to be matched to avoid excessive belt flattening), so that the embedded impurities can be exposed, and then contacted with the other rejection part 748, and the rejection work of the impurities is completed through the action of centrifugal force.

Within the technical concept of the application, various equivalent transformations of the technical solutions of the application can be made, and these equivalent transformations all belong to the protection scope of the application.
