DETAILED DESCRIPTION

[0018] 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, not all of the embodiments. 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.

[0019] In order to solve the technical problem that when the traction chain 43 is stuck with hard foreign objects in the mine, the wear between the traction chain 43, the sprocket 1 41 and the sprocket 2 42 is aggravated, and even the traction chain 43 is broken, which affects the transportation efficiency, such as Figure 1-Figure 11 and Fig.15 As shown, the following preferred technical solutions are provided: An electric automatic scraper conveyor for mining comprises a closed channel 1 and a bracket 2 fixedly arranged at the bottom of the closed channel 1, and a feeding port 40 is fixedly arranged at the top of the closed channel 1. Figure 1-Figure 2 As shown, the bracket 2 supports and fixes the closed channel 1 and other components. The closed channel 1 is used to transport materials. Since the closed channel 1 adopts a closed setting, the dust in the air can be reduced during the material transportation process, which is not only beneficial to the health of personnel, but also beneficial to the protection of the environment. Figure 5 As shown, a driving component 3 is provided on the closed channel 1, and a transmission component 4 is provided on the driving component 3. The driving component 3 can drive the transmission component 4 to operate. The transmission component 4 is arranged inside the closed channel 1, and a plurality of scraper components 5 are fixedly arranged on the transmission component 4. When the driving component 3 drives the transmission component 4 to operate, the transmission component 4 will drive the scraper component 5 to perform a circular reciprocating motion inside the closed channel 1, continuously pushing the material to move forward inside the closed channel 1, thereby realizing continuous conveying of the material.

[0020] like Figure 6 As shown, a plurality of connecting components 7 are fixedly provided on the outer walls on both sides of the closed groove 1, and anti-stuck components 6 are rotatably provided on the plurality of connecting components 7. The connecting components 7 not only play the role of limiting the installation of the anti-stuck component 6, but also are sealed and connected with the anti-stuck component 6. An air pipe 8 is externally connected to the connecting component 7, and the external air pipe 8 is connected to a gas compression device (not shown in the figure). When a hard foreign object is stuck on the transmission component 4, the gas compression device will transport high-pressure gas to the inside of the anti-stuck component 6 through the external air pipe 8 and the connecting component 7, so that the anti-stuck component 6 starts to operate and acts on the transmission component 4, thereby removing the hard foreign object from the transmission component 4 to prevent damage to the transmission component 4.

[0021] like Figure 2-Figure 3As shown, the two brackets 2 are fixedly provided with a travel assembly 9, and the travel assembly 9 is fixedly provided with a plate changing assembly 10, and the travel assembly 9 is used to drive the plate changing assembly 10 to move, as shown in FIG. Fig.15 As shown, a measuring sensor 30 is fixedly arranged on the plate changing assembly 10, and the measuring sensor 30 is used to measure whether the scraper assembly 5 is excessively worn or deformed. Figure 4 As shown, a blocking component 20 is embedded in the bottom of the closed channel 1 to control whether the interior of the closed channel 1 is in a connected state with the outside world. When the measuring sensor 30 determines that the scraper component 5 is excessively worn or deformed, the transmission component 4 continues to move with the scraper component 5, so the moving component 9 is started to align and move synchronously with the plate changing component 10 with the scraper component 5. During the movement, the worn or deformed parts on the scraper component 5 are replaced by the plate changing component 10. At the same time, the blocking component 20 is operated to connect the interior of the closed channel 1 with the outside world. The replaced old parts will naturally fall off from the opening of the blocking component 20 to the ground and then be collected uniformly.

[0022] like Figure 4 As shown, the closed channel 1 includes a channel body 11, a T-shaped groove 12 is opened at the bottom of the channel body 11, and the plugging component 20 is arranged inside the T-shaped groove 12. When the plate changing component 10 replaces the worn or deformed parts on the scraper component 5, the plugging component 20 is operated, so that the inside of the closed channel 1 is connected with the outside through the T-shaped groove 12, and the replaced old parts will naturally fall off to the ground through the T-shaped groove 12 for unified collection.

[0023] like Figure 6 and Figure 8 As shown, the connecting component 7 includes a mounting seat 71 fixedly mounted on the side wall of the channel body 11, and a sealing bearing 72 is rotatably mounted at the end surface of the mounting seat 71, and the sealing bearing 72 is fixedly connected to the hollow connecting shaft 62. The sealing bearing 72 is provided to enhance the sealing performance and prevent leakage during the high-pressure gas delivery process, thereby affecting the crushing effect of the crushing component 67 on hard foreign objects. A pair of U-shaped frames 73 are fixedly mounted on the circumferential side wall of the mounting seat 71, and an air intake valve 74 is fixedly mounted on the two U-shaped frames 73. The air intake valve 74 is fixedly connected to the sealing bearing 72, and an air pipe 8 is externally connected to the air intake valve 74. The hollow connecting shaft 62 and the air intake valve 74 are connected through the sealing bearing 72, which ensures the sealing performance without interfering with the rotation of the hollow connecting shaft 62.

[0024] like Figure 7As shown, the driving assembly 3 includes a rotating shaft 1 31 and a rotating shaft 2 36 which are rotatably mounted on both ends of the channel body 11 respectively, a transmission gear 32 is fixedly sleeved on the rotating shaft 1 31, a fixing seat 33 is fixedly mounted on the top surface of the channel body 11, a motor 34 is fixedly mounted on the fixing seat 33, and the motor 34 and the transmission gear 32 are connected through a transmission chain 35.

[0025] The transmission assembly 4 includes a pair of sprockets 41 fixedly sleeved on the rotating shaft 31, and a pair of sprockets 42 fixedly sleeved on the rotating shaft 36. The sprockets 41 and sprockets 42 are connected to each other through a traction chain 43, and a scraper assembly 5 is fixedly installed on the two traction chains 43.

[0026] The motor 34 drives the sprocket 1 41 to rotate through the transmission chain 35, the transmission gear 32 and the rotating shaft 1 31. The sprocket 1 41 drives the sprocket 2 42 and the rotating shaft 2 36 to rotate synchronously through the traction chain 43. When the two traction chains 43 rotate synchronously, they will drive the scraper assembly 5 to perform a circular reciprocating motion, continuously pushing the material inside the closed channel 1 forward, thereby achieving a continuous conveying effect.

[0027] like Figure 8-Figure 9 As shown, the anti-stuck component 6 includes a hollow connecting shaft 62 rotatably mounted on the connecting component 7, and a disc 61 is fixedly mounted on one end of the hollow connecting shaft 62 away from the connecting component 7. A cavity 63 is opened inside the disc 61, and the cavity 63 is connected to the hollow connecting shaft 62. The purpose is that when a hard foreign object is stuck on the transmission component 4, the gas compression device can transport high-pressure gas to the inside of the cavity 63 through the external air pipe 8, the connecting component 7 and the hollow connecting shaft 62. A plurality of air channels 64 are opened inside the disc 61, and the plurality of air channels 64 are respectively connected to the cavity 63. An electronic valve 65 is fixedly installed at the connection between the airway 1 64 and the cavity 63. By opening and closing the electronic valve 65, it is possible to control whether the high-pressure gas inside the cavity 63 enters the airway 1 64. A plurality of slide grooves 66 are also provided on the disc 61. The airway 1 64 and the slide groove 66 are connected. A crushing assembly 67 is slidably installed in the slide groove 66, and the crushing assembly 67 is meshed with the transmission assembly 4. A position sensor 2 69 is fixedly installed on the inner side wall of the slide groove 66, and a position sensor 1 68 is fixedly installed on the side wall of the crushing assembly 67 facing the position sensor 2 69.

[0028] Since the crushing assembly 67 is meshed with the transmission assembly 4, when the transmission assembly 4 is stuck with a hard foreign object, the crushing assembly 67 will encounter resistance during meshing, causing the crushing assembly 67 to slide inside the slide groove 66. When the position sensor 1 68 on the crushing assembly 67 contacts the position sensor 2 69, it means that the crushing assembly 67 has reached the maximum sliding distance. At this time, the electronic gas valve 65 is opened, and the high-pressure gas inside the cavity 63 enters the crushing assembly 67 through the electronic gas valve 65 and the airway 1 64, so that the crushing assembly 67 can crush the hard foreign object stuck on the transmission assembly 4. The hard foreign bodies are crushed to prevent damage to the transmission component 4 by hard foreign bodies. Since multiple anti-stuck components 6 are set, hard foreign bodies can be crushed multiple times to prevent the problem that hard foreign bodies still remain on the transmission component 4 due to incomplete crushing. Moreover, with this setting method, hard foreign bodies stuck on the transmission component 4 can be crushed in real time, which not only protects the transmission component 4, but also does not require shutdown for cleaning. Cleaning can be achieved during the material transportation process, thereby improving the transportation efficiency. There is no need for manual operation by personnel, which reduces the risk of personal injury, improves maintenance efficiency, and saves manpower.

[0029] like Figure 10-11 As shown, the crushing assembly 67 includes a tooth 671 slidably mounted in the slide groove 66, the traction chain 43 is meshed with the tooth 671, and the tooth 671 is elastically connected to the inner side wall of the slide groove 66 (not shown in the figure) for realizing the reset of the tooth 671. The interior of the tooth 671 is provided with an air passage 672, and the air passage 672 is connected to the slide groove 66. The oblique surface of the tooth 671 is also provided with an air passage 673, and the air passage 673 is connected to the inner side wall of the slide groove 66. Airway two 672 is connected, and both airway two 672 and airway three 673 are used to transport high-pressure gas. A mounting ring one 674 is fixedly installed on the inner wall of airway three 673, and a connecting ring 675 is rotatably installed on the mounting ring one 674. A hammer 676 is installed on the internal thread of airway three 673, and the hammer 676 and the connecting ring 675 are elastically connected by a spring one 677. The hammer 676 is used to break hard foreign objects stuck on the traction chain 43.

[0030] When the tooth 671 encounters resistance from a hard foreign body, the tooth 671 will slide inside the slide groove 66. When the tooth 671 slides to the maximum moving distance, the airway 2 672 is aligned with the airway 1 64 and is in a connected state. At this time, the electronic gas valve 65 is opened, and the high-pressure gas inside the cavity 63 enters the inside of the airway 3 673 through the electronic gas valve 65, the airway 1 64 and the airway 2 672, and pushes the hammer 676 to extend outward from the airway 3 673. Since the hammer 676 is threadedly installed inside the airway 3 673, the hammer 676 will extend outward from the airway 3 673 in a rotating manner to break the hard foreign body stuck on the traction chain 43. The crushing effect is better by rotating. Since the connecting ring 675 is rotatably installed on the mounting ring 674, it will not interfere with the rotation of the hammer 676. Since the traction chain 43 has tension, even if the hammer 676 fails to break the hard foreign matter on the traction chain 43 at one time, under the tension of the traction chain 43, the tooth 671 can continue to engage and rotate with the traction chain 43, and the traction chain 43 and the tooth 671 will not be stuck. When the tooth 671 passes over the hard foreign matter that has not been completely broken, under the elastic force of the spring 1 677, the hammer 676 rotates in the opposite direction and contracts to the inside of the airway three 673 for next use.

[0031] In order to solve the technical problems that the scraper plate 59 is worn or deformed by collision with hard foreign objects, which will lead to a decrease in conveying efficiency, and the deformed scraper plate 59 may also rub against the inner wall of the closed groove 1, causing damage to the inner wall of the closed groove 1, such as Figure 3-Figure 19 As shown, the following preferred technical solutions are provided: like Figure 7 and Figure 12-14As shown, the scraper assembly 5 includes a connecting seat 51 fixedly mounted on the traction chain 43, a pair of long grooves 52 are symmetrically opened on the connecting seat 51, and long rods 510 are respectively arranged inside the two long grooves 52, and the bottom surface of the long rod 510 is elastically connected to the inner wall of the long groove 52 by a spring 2 520. The setting of the long groove 52 and the spring 2 520 can limit the long rod 510 to ensure that the long rod 510 can only achieve vertical sliding inside the long groove 52, and a plurality of permanent magnets 530 are fixedly installed on the side wall of the long rod 510, and an installation groove 53 is opened on the connecting seat 51, and a scraper plate 59 is installed inside the installation groove 53, and a plurality of pairs of installation holes 54 are opened inside the connecting seat 51, and the long groove 52 and the installation groove 53 are connected by installation holes 54. The hole 54 is connected, and a mounting ring 2 55 is fixedly installed inside the mounting hole 54. A clamping column 56 is also slidably installed inside the mounting hole 54. The clamping column 56 and the mounting ring 2 55 are elastically connected by a spring 3 57. The clamping column 56 and the scraper plate 59 can form a clamping relationship for fixing the scraper plate 59. A permanent magnet 2 58 is fixedly installed on the side wall of the clamping column 56 facing the long rod 510, and the permanent magnet 1 530 has opposite magnetic poles to the permanent magnet 2 58. A positioning groove 540 is provided on the side wall of the connecting seat 51 facing the plate changing assembly 10. The positioning groove 540 is used to realize the positioning of the scraper assembly 5 to prevent the scraper assembly 5 from having position deviation when the scraper plate 59 is replaced by the plate changing assembly 10, thereby preventing the scraper assembly 5 from being unable to be replaced.

[0032] like Figure 3 , Figure 5 and Figure 7 As shown, the moving assembly 9 includes a pair of slide rails 91 fixedly mounted on the bracket 2, and a servo trolley 92 is slidably mounted on the two slide rails 91 respectively. The servo trolley 92 is used to drive the plate changing assembly 10 to move on the slide rails 91, thereby realizing the synchronous movement of the plate changing assembly 10 and the scraper assembly 5, which is conducive to replacing the scraper plate 59 without stopping the machine.

[0033] like Figure 3 and Figure 15-19As shown, the plate changing assembly 10 includes a U-shaped base 101 fixedly mounted on two servo carriages 92, a measuring sensor 30 is embedded and fixedly mounted on the side wall of the U-shaped base 101 facing the scraper assembly 5, a slide 102 is embedded and slidably mounted on the U-shaped base 101, the U-shaped base 101 plays a supporting and limiting role for the slide 102, and a spare scraper plate 59 is placed on the slide 102, an L-shaped bracket 103 is fixedly mounted on the side wall of the U-shaped base 101, and an electric telescopic column 104 and an electric telescopic column 2 105 are respectively fixedly mounted on the L-shaped bracket 103, and the electric telescopic column 104 and the electric telescopic column 105 are respectively fixedly mounted on the L-shaped bracket 103. A connecting plate 106 is fixedly installed at the output end of 04, and a pair of pressure rods 107 are symmetrically fixedly installed on the side walls of the connecting plate 106. The pressure rods 107 are used to apply pressure to the long rod 510, so that the long rod 510 slides downward inside the long groove 52, thereby making the permanent magnet 1 530 and the permanent magnet 2 58 aligned. The permanent magnet 1 530 attracts the permanent magnet 2 58, and the clamping column 56 is pulled out from the scraper plate 59, so that the restrictive relationship between the scraper plate 59 and the clamping column 56 is released, and the old scraper plate 59 will fall off from the connecting seat 51, which is conducive to the subsequent replacement of the new scraper plate 59.

[0034] A positioning rod 108 is also fixedly installed on the side wall of the connecting plate 106. Before replacing the scraper plate 59, the plate changing assembly 10 is first positioned by the positioning rod 108 and the positioning groove 540 to prevent the plate changing assembly 10 from having position deviation when replacing the scraper plate 59, and then becoming unable to be replaced. A through groove 109 is opened on the positioning rod 108, and the length of the through groove 109 is slightly larger than the length of the scraper plate 59. The purpose is that after the spare scraper plate 59 is used up, the staff can replenish the spare scraper plate 59 into the slide seat 102 through the through groove 109, thereby avoiding the situation where the positioning rod 108 hinders the staff from replenishing the spare scraper plate 59. A pair of flip assemblies 110 are symmetrically fixedly installed on the bottom surface of the connecting plate 106, such as Figure 17-Figure 18 As shown, the flip assembly 110 can only be flipped clockwise.

[0035] like Fig.17 and Fig.19 As shown, the flip assembly 110 includes a pair of mounting ears 111 fixedly mounted on the bottom surface of the connecting plate 106, and a circular shaft is fixedly mounted on the two mounting ears 111 together, and a flip plate 112 is rotatably sleeved on the circular shaft, and the flip plate 112 and the mounting ears 111 are elastically connected by a torsion spring 113, and an electromagnet 114 is fixedly mounted on the side wall of the flip plate 112 facing the slide 102, and a permanent magnet three 115 is embedded and fixedly mounted on the side wall of the slide 102 facing the flip plate 112, and the permanent magnet three 115 is aligned with the electromagnet 114.

[0036] like Figure 4As shown, the blocking assembly 20 includes a blocking plate 202 slidably mounted inside the T-slot 12 , and an electric telescopic column 3 201 is also fixedly mounted inside the T-slot 12 , and the output end of the electric telescopic column 3 201 is fixedly connected to the blocking plate 202 .

[0037] Specifically, when the measuring sensor 30 determines that the scraper plate 59 is excessively worn or deformed, the traction chain 43 continues to move the scraper assembly 5, and the servo trolley 92 is started to drive the plate changing assembly 10 to move on the slide rail 91, so that the plate changing assembly 10 and the scraper assembly 5 are aligned and move synchronously. During the movement, the electric telescopic column 104 moves toward the direction close to the scraper assembly 5 through the connecting plate 106 with the pressure rod 107 and the positioning rod 108. Figure 16-Figure 17 As shown, in the process of the electric telescopic column 104 moving with the connecting plate 106, since the elastic force of the torsion spring 113 is large enough, the flip plate 112 will not flip when it conflicts with the slide seat 102, and will push the slide seat 102 and the spare scraper plate 59 to slide synchronously on the U-shaped base 101. When the slide seat 102 conflicts with the connecting seat 51, the slide seat 102 reaches the maximum moving distance. At this time, the electric telescopic column 104 continues to extend. When the thrust of the electric telescopic column 104 is greater than the elastic force of the torsion spring 113, the flip plate 112 starts to flip, which will not affect the normal movement of the connecting plate 106, while the slide seat 102 and the spare scraper plate 59 stay at the position of conflicting with the connecting seat 51. like Fig.18 As shown, when the connecting plate 106 continues to move, since the length of the positioning rod 108 is greater than the length of the pressure rod 107, and since the volume of the distal end of the positioning rod 108 is smaller than the volume of the opening of the positioning groove 540, the positioning rod 108 will first be inserted into the interior of the positioning groove 540 to position the scraper assembly 5, so that the scraper assembly 5 and the plate replacement assembly 10 are in an integrated state, preventing the scraper assembly 5 from shaking on the traction chain 43, which is not conducive to the subsequent replacement of the scraper plate 59. As the electric telescopic column 104 continues to extend, the pressure rod 107 will be inserted into the interior of the long groove 52 and exert pressure on the long rod 510, so that the long rod 510 is The inside of the long slot 52 slides vertically downward, and finally the permanent magnet 1 530 is aligned with the permanent magnet 2 58. The permanent magnet 1 530 attracts the permanent magnet 2 58, and the clamping column 56 is pulled out from the scraper plate 59, so that the restriction relationship between the scraper plate 59 and the clamping column 56 is released, and the old scraper plate 59 will fall off from the connecting seat 51. At the same time, the electric telescopic column three 201 drives the sealing plate 202 to slide, so that the T-slot 12 becomes open, and then the inside of the closed channel 1 is connected with the outside world, and the old scraper plate 59 will naturally fall off from the opening of the sealing component 20 to the ground for unified collection.

[0038] After the old scraper plate 59 falls off, the electric telescopic column 2 105 is started to extend. When the electric clamping component (not shown in the figure) at the end of the electric telescopic column 2 105 reaches the position of the spare scraper plate 59, the spare scraper plate 59 is clamped by the electric clamping component, and then the electric telescopic column 2 105 continues to extend until the spare scraper plate 59 is pushed into the installation groove 53 to stop and position. Then the electric telescopic column 1 104 is reset with the pressure rod 107 and the positioning rod 108 through the connecting plate 106. When the flip plate 112 reaches the edge of the slide 102, the flip plate 112 is flipped and reset under the elastic force of the torsion spring 113 and is tightly attached to the side wall of the slide 102. Then the electromagnet 114 is energized, so that the electromagnet 114 attracts the permanent magnet 3 115, thereby driving the slide 102 to reset together. After the slide 102 is reset, the electromagnet 114 is powered off. like Figure 12-14 As shown, when the pressure rod 107 is pulled out from the inside of the long slot 52, under the elastic force of the second spring 520, the long rod 510 and the permanent magnet 1 530 move upward together in the long slot 52, so that the permanent magnet 1 530 and the permanent magnet 2 58 are misaligned, and the attraction effect is cancelled. Therefore, under the elastic force of the third spring 57, the clamping column 56 restores the clamping relationship with the scraper plate 59, and then the electric telescopic column 2 105 drives the electric clamping component (not shown in the figure) at the end to reset. The above operations can complete the replacement of the scraper plate 59.

[0039] Through the above arrangement, when the measuring sensor 30 determines that the scraper plate 59 is excessively worn or deformed, the worn or deformed part of the scraper plate 59 can be replaced without stopping the machine, which not only saves manpower but also reduces the impact on the conveying efficiency.
