[0045] Specifically, the deviation-reducing and pressure-reducing adapter 420 supports the deviation-reducing and pressure-reducing driven shaft 430, the lower conveying belt 300 rotates through the deviation-reducing and pressure-reducing driven shaft 430, the deviation-reducing and pressure-reducing driven shaft 430 rotates with the movement of the lower conveying belt 300, and the buffer assembly is in contact with the upper conveying belt 300, thereby reducing the pressure on the upper conveying belt 300, and due to the presence of the buffer assembly, the user can add the coal to be transported to the conveying belt 300 at the position provided with the buffer assembly, thereby reducing the pressure on the conveying belt 300, and further protecting the conveying belt 300 from tearing due to too much pressure.

[0048] Specifically, the first buckle protrusion 442 and the second buckle protrusion 443 are in triangular shape, so that the first buckle protrusion 442 and the second buckle protrusion 443 can withstand greater impact force.

[0049] Meanwhile, the second buffering rotating part 445 is parallel to the bottom surface of the buffering main part 441, and the first buffering rotating part 444 and the second buffering rotating part 445 form an angle of 120°, and the third buffering rotating part 446 and the second buffering rotating part 445 form an angle of 120°, so that the conveying belt 300 passing through the buffering assembly is supported by the first buffering rotating part 444 and the second buffering rotating part 445, and the pressure on the conveying belt 300 is transferred to the first buffering rotating part 444, the second buffering rotating part 445 and the third buffering rotating part 446, and the first buffering rotating part 444 and the third buffering rotating part 446 form an angle with the second buffering rotating part 445, which can prevent the conveying belt 300 from deviating.

[0050] Further, the first buffering rotating part 444, the second buffering rotating part 445 and the third buffering rotating part 446 can be made of rubber or other elastic materials.

[0051] Further, the pressure reduction groove 447 on the first buffering rotating part 444, the second buffering rotating part 445 and the third buffering rotating part 446 can reduce the contact area with the conveying belt 300, so that the first buffering rotating part 444, the second buffering rotating part 445 and the third buffering rotating part 446 can be deformed to a certain extent, that is, the conveying belt 300 is reduced in pressure.

[0054] Meanwhile, the lower conveying belt 300 rotates through the secondary deviation correction conveying shaft 540, the secondary deviation correction conveying shaft 540 plays a role of support for the conveying belt 300, then the secondary deviation correction support part 550 plays a role of fixed support for the secondary deviation correction first transmission roller 560, the secondary deviation correction second transmission roller 570 and the secondary deviation correction third transmission roller 580, and the secondary deviation correction first transmission roller 560 and the secondary deviation correction third transmission roller 580 are at a certain angle with the secondary deviation correction second transmission roller 570, thereby playing a role of limiting for the conveying belt 300, avoiding the position deviation of the conveying belt 300, and further playing a role of support for the conveying belt 300, thereby ensuring the stability of the rotation of the conveying belt 300.

[0055] In the embodiment, the first deviation correction detection assembly 520 and the second deviation correction detection assembly 530 are of the same structure; the first deviation correction detection assembly 520 comprises a deviation correction detection signaler 521, an angle detection sensor 522, a detection linkage rod 523 and an angle detection deviation shaft 524, the deviation correction detection signaler 521 is installed in the secondary deviation correction support 510, the angle detection sensor 522 is rotatably connected to one side of the deviation correction detection signaler 521, the detection linkage rod 523 is installed on the angle detection sensor 522, and the angle detection deviation shaft 524 is installed at the end of the detection linkage rod 523 and extends to one side of the conveying belt 300.

[0056] The first deviation correction detection assembly 520 is installed on one side of the conveying belt 300, and the second deviation correction detection assembly 530 is installed on the other side of the conveying belt 300, so that the first deviation correction detection assembly 520 and the second deviation correction detection assembly 530 cooperate with each other to detect the position deviation on both sides of the conveying belt 300;

[0057] Specifically, the deviation correction detection signaler 521 supports the angle detection sensor 522, and the deviation correction detection signaler 521 is connected with an external operating system, so that when the angle detection sensor 522 detects that the displacement of the angle detection displacement shaft 524 exceeds a warning value, the angle detection sensor 522 sends an electrical signal to the deviation correction detection signaler 521, and the deviation correction detection signaler 521 sends a shutdown signal to the external operating system, so as to avoid tearing of the conveying belt 300 caused by position deviation of the conveying belt 300;

[0058] More specifically, the angle detection displacement shaft 524 extends to one side of the conveying belt 300, and when the conveying belt 300 is normally running, the conveying belt 300 does not contact the angle detection displacement shaft 524, and when the conveying belt 300 has position deviation, the conveying belt 300 contacts the angle detection displacement shaft 524, so that the angle detection displacement shaft 524 drives the angle detection sensor 522 to rotate through the detection linkage rod 523, and when the angle detection sensor 522 detects that the angle rotation exceeds a warning value, a shutdown signal is sent, so as to effectively avoid position deviation of the conveying belt 300 during running;
