[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 7 As shown, the coal mine electromechanical transmission and transportation device 100 of the embodiment of the present invention includes a frame 1, a driving part (not shown in the figure), a conveyor belt 2, a scraper 3 and a driving assembly 4. The driving part is arranged on the frame 1, and the conveyor belt 2 is arranged on the frame 1. The driving part is connected to the conveyor belt 2, and the driving part drives the conveyor belt 2 to rotate so that the conveyor belt 2 transports coal. The scraper 3 moves along a preset direction (for example, Figure 1 The scraper plate 3 is movably mounted on the frame 1 in the vertical direction. The scraper plate 3 is provided with a scraping opening. The conveyor belt 2 is passed through the scraping opening. The outer side of the conveyor belt 2 located in the scraping opening abuts or is adjacent to the scraper plate 3. The drive assembly 4 is mounted on the frame 1 and connected to the scraper plate 3 to drive the scraper plate 3 to move in the preset direction.

[0034] When the electromechanical transmission and transportation device 100 of a coal mine according to an embodiment of the present invention is in use, the drive unit drives the conveyor belt 2 to rotate, and the upper portion of the outer side surface of the conveyor belt 2 carries coal. When coal particles remain on the conveyor belt 2, that is, when coal particles remain on the outer side surface of the conveyor belt 2, as the conveyor belt 2 rotates, the conveyor belt 2 passes through the scraper opening. Since the scraper plate 3 is adjacent to or abuts the outer side surface of the conveyor belt 2, the coal particles on the outer side surface of the conveyor belt 2 can be scraped off. The drive assembly 4 drives the scraper plate 3 to reciprocate in the preset direction. The scraper plate 3 drives the portion of the conveyor belt 2 located in the scraper opening to reciprocate, forming a motion form in which the portion of the conveyor belt 2 and the scraper plate 3 vibrate simultaneously, thereby shaking off the coal particles on the conveyor belt 2 and the coal particles attached to the scraper plate 3, thereby cleaning the conveyor belt 2 and the scraper plate 3, recovering the coal particles, and ensuring the normal transportation of coal by the conveyor belt 2.

[0035] The coal mine electromechanical transmission conveying device 100 of the embodiment of the present application passes through the scraping port of the scraper 3 through the conveying belt 2, which can scrape the coal particles on the conveying belt 2 by the scraper 3, and remove most of the large particles or the coal accumulated and adhered on the conveying belt 2. On the other hand, the scraper 3 is driven to reciprocate in the preset direction by the driving member, so as to form the vibration effect of the scraper 3, which can shake off the coal adhered on the scraper 3 and the coal particles adhered on the conveying belt 2, so as to realize the recovery of the coal and the cleaning of the conveying belt 2 and the scraper 3, and ensure the normal conveying operation of the conveying belt 2 on the coal.

[0036] In order to make the scheme of the present application easier to understand, the same as the preset direction and the up-down direction is taken as an example for description, the up-down direction 1 to Figure 7 As shown in the figure, the left-right direction is as shown in 1 to Figures 1 to 3 and Figure 5 , Figure 6 As shown in the figure, the front-rear direction is as shown in 1 to Figure 4 .

[0037] The coal mine electromechanical transmission conveying device 100 of the embodiment of the present application comprises a frame body 1, a driving part, a conveying belt 2, a scraper 3, a driving assembly 4, a guide plate 5, an elastic supporting member 6, a buffer member 7 and a tensioning assembly 8.

[0038] The driving part is arranged on the frame body 1, and the conveying belt 2 is arranged on the frame body 1. The driving part is connected with the conveying belt 2, and drives the conveying belt 2 to rotate so as to convey the coal. The scraper 3 is movably arranged on the frame body 1 in the preset direction. The scraper 3 is provided with a scraping port, and the conveying belt 2 is arranged in the scraping port. The outer side of the conveying belt 2 in the scraping port abuts or is adjacent to the scraper 3. The driving assembly 4 is arranged on the frame body 1, and is connected with the scraper 3 to drive the scraper 3 to move in the preset direction.

[0039] In some embodiments, the scraper 3 comprises a connecting part 31 and a scraper part 32. The connecting part 31 is movably arranged on the frame body 1, and the two ends of the scraper part 32 are detachably connected with the connecting part 31. The scraper part 32 has a blade part, and the blade part and the connecting part 31 form the scraping port. The blade part abuts or is adjacent to the outer side of the conveying belt 2. The detachable connection between the scraper part 32 and the connecting part 31 facilitates the installation of the scraper 3 and the cooperation with the conveying belt 2, improves the assembly efficiency of the coal mine electromechanical transmission conveying device 100 of the embodiment of the present application, and facilitates the disassembly of the scraper part 32, so as to facilitate the maintenance and replacement of the scraper part 32, thereby ensuring the cleaning effect of the scraper 3 on the conveying belt 2, ensuring that the coal particles adhered on the conveying belt 2 are scraped off, and improving the coal recovery rate.

[0040] As shown in the figure, the left-right direction is as shown in 1 to Figure 2 , Figure 3 and Figure 7As shown, the frame body 1 is provided with a mounting hole 11 extending along the preset direction, the scraping plate 3 is located in the mounting hole 11, the driving assembly 4 comprises a driving motor 41, a cam 42 and a connecting block 43, the driving motor 41 is arranged on the frame body 1, the driving motor 41 is located on the outer side of the frame body 1, the cam 42 is arranged on the output shaft of the driving motor 41, the connecting block 43 is located above the cam 42, the connecting block 43 is connected with the scraping plate 3, the connecting block 43 has an abutting portion 431, the abutting portion 431 is arc-shaped, and the abutting portion 431 abuts against the cam 42. After the driving motor 41 is turned on, the output shaft of the driving motor 41 rotates, thereby driving the cam 42 to rotate, the abutment between the cam 42 and the connecting portion 31 of the connecting block 43 drives the connecting block 43 to move up and down, thereby driving the scraping plate 3 to move up and down. The driving assembly 4 of the embodiment of the present application adopts the output power of the driving motor 41, and drives the connecting block 43 and the scraping plate 3 to move up and down through the cam 42, and the transmission movement of the cam 42 and the connecting block 43 drives the scraping plate 3 to move up and down, which has low cost and good stability.

[0041] In some embodiments, as shown in Figure 2 and Figure 7 , the driving assembly 4 further comprises a reset member 44, the reset member 44 comprises a fixed block 441, a first telescopic sleeve 442 and a first spring 443, the fixed block 441 is arranged on the frame body 1, the fixed block 441 is located above the connecting block 43, the two ends of the first telescopic sleeve 442 are connected with the fixed block 441 and the connecting block 43 respectively, the two ends of the first spring 443 are connected with the fixed block 441 and the connecting block 43 respectively, and the first spring 443 is sleeved on the first telescopic sleeve 442. The first spring 443 is a compression spring, the first spring 443 has a pressing force towards the connecting block 43, thereby ensuring the fitting degree of the connecting block 43 and the cam 42, ensuring the movement transmission between the cam 42 and the connecting block 43, and ensuring the connecting block 43 to follow the descent of the cam 42, thereby ensuring the timely reset of the connecting block 43, ensuring the reset of the scraping plate 3 in time, ensuring the smoothness of the up-and-down reciprocating movement of the scraping plate 3, thereby ensuring the shaking-off effect on the coal particles, improving the recovery rate of the coal, and improving the cleaning effect of the conveying belt 2 and the scraping plate 3.

[0042] As shown in Figure 1 , Figure 3 and Figure 4As shown, the frame 1 is provided with a guide port 12, and the guide plate 5 is located on the outside of the conveyor belt 2. The guide plate 5 is provided at the guide port 12. In the preset direction, one end (front end) of the guide plate 5 is adjacent to the conveyor belt 2 relative to the other end (rear end), so that the one end of the guide plate 5 is higher than the other end. The portion of the guide plate 5 adjacent to the one end is opposite to the scraper plate 3 in the preset direction, that is, the front portion of the guide plate 5 is opposite to the scraper plate 3 in the vertical direction. Then, the coal particles shaken off from the conveyor belt 2 and the scraper plate 3 fall onto the guide plate 5, slide on the guide plate 5 to the lower end of the guide plate 5, and then slide out of the frame 1. The guide plate 5 facilitates the diversion of the shaken-off coal particles to the outside of the frame 1 for the purpose of recovering the coal particles.

[0043] The elastic support member 6 includes a support plate 61, a connecting tube 62, a second telescopic sleeve 63, and a second spring 64. The support plate 61 is disposed on the inner side of the frame 1 and is located on the side of the guide plate 5 facing away from the conveyor belt 2. The second telescopic sleeve 63 extends along the predetermined direction. The two ends of the second telescopic sleeve 63 are respectively connected to the support plate 61 and the connecting tube 62. The connecting tube 62 is connected to the guide plate 5. The two ends of the second spring 64 are respectively connected to the support plate 61 and the connecting tube 62. The second spring 64 is sleeved on the second telescopic sleeve 63. The elastic support member 6 not only provides support for the guide plate 5 but also provides margin for upward and downward movement of the guide plate 5. When the guide plate 5 reciprocates up and down, the second telescopic sleeve 63 and the second spring 64 also expand and contract accordingly. Moreover, the elastic force of the second spring 64 causes the guide plate 5 to move upward and reset. When the coal particles are shaken off onto the guide plate 5, if the weight of the coal particles is large, or when a person actively presses the guide plate 5 downward, the guide plate 5 will move downward, thereby shortening the second telescopic sleeve 63 and shortening the second spring 64 to store force. The stored force of the second spring 64 makes the guide plate 5 tend to move upward and rebound, causing the guide plate 5 to vibrate back and forth briefly. The up and down vibration of the guide plate 5 makes it easier for the coal particles to fall through the guide plate 5, and also prevents the coal particles from adhering to the guide plate 5, thereby improving the recovery rate of the coal particles.

[0044] The buffer 7 connects the one end (front end) of the guide plate 5 and the scraping plate 3, so that the guide plate 5 and the scraping plate 3 can transmit motion, so that when the scraping plate 3 vibrates up and down, a part of the motion can be transmitted to the guide plate 5, thereby driving the guide plate 5 to vibrate up and down, so that when the coal particles are lighter and cannot cause the guide plate 5 to vibrate up and down, the vibration of the guide plate 5 can also be realized, thereby further ensuring the guiding effect of the guide plate 5 on the coal particles and the recovery rate of the coal. Moreover, the buffer 7 has a buffering effect, can avoid hard linking between the scraping plate 3 and the guide plate 5, absorb kinetic energy transmitted between the guide plate 5 and the scraping plate 3, buffer the motion transmitted between the guide plate 5 and the scraping plate 3, improve the stability of the vibration of the guide plate 5 and the scraping plate 3, and ensure the stability of the coal mine electromechanical transmission conveying device 100 of the embodiment.

[0045] Specifically, the buffer 7 includes a third telescopic sleeve 71 and a third spring 72, both ends of the third telescopic sleeve 71 are connected to the guide plate 5 and the scraping plate 3 respectively, and the third spring 72 is sleeved on the third telescopic sleeve 71, both ends of the third spring 72 abut against the guide plate 5 and the scraping plate 3. The third telescopic sleeve 71 and the third spring 72 connect the guide plate 5 and the scraping plate 3, and the third spring 72 can absorb a part of the kinetic energy transmitted between the guide plate 5 and the scraping plate 3 through deformation, which has a simple structure and low cost, and is conducive to reducing the cost of the coal mine electromechanical transmission conveying device 100 of the embodiment.

[0046] In some embodiments, the buffer 7 further includes a rubber block 73, the rubber block 73 is arranged on the guide plate 5, the rubber block 73 is connected to the third telescopic sleeve 71, and the third spring 72 abuts against the rubber block 73. The rubber block 73 has a certain damping effect, which not only realizes the connection of the third spring 72 and the guide plate 5, but also further forms a buffering effect, improves the stability of the vibration of the guide plate 5 and the scraping plate 3, and ensures the stability of the coal mine electromechanical transmission conveying device 100 of the embodiment.

[0047] In some embodiments, the frame body 1 is provided with an adjusting hole 13, the tensioning assembly 8 includes a tensioning roller 81 and a tensioning piece 82, the tensioning roller 81 is movably arranged on the adjusting hole 13, and the tensioning roller 81 is located on the inner side of the conveying belt 2 and abuts against the conveying belt 2. The tensioning piece 82 is arranged on the frame body 1, and the tensioning piece 82 is connected with the tensioning roller 81 to drive the tensioning roller 81 to move, so as to adjust the position of the tensioning roller 81, and then adjust the tensioning degree of the conveying belt 2, so as to ensure that the conveying belt 2 can always be kept tensioned, and ensure the normal operation of the conveying belt 2.

[0048] Specifically, referring to Figures 1 to 5The two tension rollers 81 are respectively located at the left and right sides of the scraping plate 3, and the two ends of the tension roller 81 are connected with a tension piece 82 located at the outer side of the frame body 1. The tension piece 82 comprises a first rotating block 821, a second rotating block 822, a fourth telescopic sleeve 823 and a fourth spring 824. The first rotating block 821 is located at the outer side of the frame body 1, and the first rotating block 822 is rotatably connected with the tension roller 81. The second rotating block 822 is rotatably arranged at the outer side of the frame body 1. The two ends of the fourth telescopic sleeve 823 are fixedly connected with the first rotating block 821 and the first rotating block 822, respectively. The fourth spring 824 is sleeved on the fourth telescopic sleeve 823, and the two ends of the fourth spring 824 are connected with the first rotating block 821 and the second rotating block 822, respectively. When the driving assembly 4 drives the scraping plate 3 to vibrate, the part of the conveying belt 2 located in the scraping port has the maximum vibration amplitude. When the vibration is transmitted to the position of the tension roller 81, the tension roller 81 is driven to vibrate. The fourth telescopic sleeve 823 of the tension piece 82 can provide a movement allowance for the vibration of the tension roller 81. The fourth spring 824 forms a pressing force on the first rotating block 821, that is, the fourth spring 824 forms a pressing force on the tension roller 81, consumes the vibration energy of the tension roller 81, reduces the vibration amplitude of the tension roller 81, and reduces the continuous transmission of the vibration to the upper part of the conveying belt 2, thereby ensuring the stability and tension degree of the upper part of the conveying belt, that is, the part used for transporting coal, and ensuring the coal transportation function of the coal mine mechanical and electrical transmission and transportation device 100.
