[0045] The specific implementation is as follows: the cover plate 10 is used to support and hold the transfer machine 4, and one end of the cover plate 10 is set as an inclined surface, so that the swing mechanism 42 can rotate and swing on the mounting mechanism 41, and the cover plate 10 can expand the swing range of the swing mechanism 42 to avoid the cover plate 10 limiting the swing angle of the swing mechanism 42.

[0046] In another embodiment provided by the present invention, the transfer machine 4 further includes a mounting cylinder 47, which is symmetrically arranged on both sides of the mounting plate 40, and each of the mounting cylinders 47 is provided with a first hydraulic rod 48, and an angle bracket 49 is provided at the protruding end of the first hydraulic rod 48, and the upper end of the angle bracket 49 is connected to the lower end of the mounting plate 40;

[0047] The specific implementation method is as follows: during the use of the transfer machine 4, the transfer machine 4 at different heights is required in different working environments. In order to adapt to different working environments and to improve the applicability of the transfer machine 4, the first hydraulic rod 48 drives the mounting plate 40 to rise and fall through the angle bracket 49, so that the mounting plate 40 drives the transfer machine 4 to rise and fall, that is, the first hydraulic rod 48 adjusts the distance between the transfer machine 4 and the crawler assembly 3 through the angle plate and the mounting plate 40, so that the transfer machine 4 can be at different heights according to different working environments, thereby improving the applicability of the transfer machine 4.

[0048] In another embodiment provided by the present invention, the mounting mechanism 41 includes two side plates 410, the two side plates 410 are fixedly connected to the upper end of the mounting plate 40, and one end of the side plate 410 close to the swing mechanism 42 is rotatably provided with a conveying roller 45;

[0049] The specific implementation is as follows: the side plate 410 is fixedly mounted on the mounting plate 40, so that when the first hydraulic rod 48 drives the mounting plate 40 to rise and fall through the angle bracket 49, the side plate 410 can be synchronously raised and lowered with the mounting plate 40, so that the side plate 410 and the mounting plate 40 drive the transfer machine 4 to rise and fall synchronously to adjust the position height, and the side plate 410 can limit the side of the conveyor belt 46 to prevent the conveyor belt 46 from shifting during operation, and at the same time, the side plate 410 can also support and limit the swing mechanism 42 to provide an installation position for the swing mechanism 42.

[0050] In another embodiment provided by the present invention, the swing mechanism 42 includes two swing plates 420, one end of the swing plate 420 away from the mounting mechanism 41 is rotatably provided with the conveying roller 45, the other end of the swing plate 420 is rotatably provided on the mounting mechanism 41, and the rotation center of the swing plate 420 coincides with the rotation center of the conveying roller 45 at one end of the mounting mechanism 41, the lower end of each swing plate 420 is rotatably provided with one end of a second hydraulic rod 421, the other end of each second hydraulic rod 421 is rotatably provided at the upper end of the cover plate 10, and the end of the swing plate 420 close to the mounting mechanism 41 is rotatably provided with a first limiting roller 422;

[0051] The specific implementation is as follows: according to the environment, the extended end of the second hydraulic rod 421 can be extended and retracted along its own central axis, so that the second hydraulic rod 421 drives the swing plate 420 connected thereto to rotate along the side plate 410, so that the second hydraulic rod 421 adjusts the swing plate 420 to a suitable position, ensuring that the conveyor belt 46 at the swing mechanism 42 can transport ore at the most suitable position and angle, and when the swing plate 420 drives the conveyor roller 45 installed thereon to rotate along the side plate 410, in order to ensure that there is no large gap between the conveyor belt 46 and the conveyor roller 45, the conveyor belt 46 is limited and guided by setting a first limiting roller 422, so that the conveyor belt 46 and the conveyor roller 45 on the side plate 410 are closely fitted, ensuring the transmission between the conveyor roller 45 and the conveyor belt 46.

[0052] In another embodiment provided by the present invention, the telescopic mechanism 43 includes a fixed plate 430, which is arranged between the mounting mechanisms 41, and a movable plate 431 is slidably arranged at one end of the fixed plate 430 away from the swing mechanism 42, and a third hydraulic rod 432 is arranged in the middle of the fixed plate 430, and the extended end of the third hydraulic rod 432 is connected to the middle of the movable plate 431, and a conveying roller 45 and a second limiting roller 433 are rotatably arranged on the movable plate 431, and an L-shaped plate 434 is arranged at the lower end of the movable plate 431, and an adjusting roller 435 is rotatably arranged at one end of the L-shaped plate 434 away from the movable plate 431, and two steering rollers 436 are rotatably arranged between the mounting mechanisms 41;

[0053] The specific implementation is as follows: during the use of the transfer machine 4, when the transfer machine 4 is connected to two different transportation systems, the two different transportation systems may be too far apart or too close to each other. To adapt to this situation, the third hydraulic rod 432 drives the movable plate 431 to move along the fixed plate 430, so that the total length between the movable plate 431 and the fixed plate 430 changes in time according to the interval between the two different systems, so that the conveyor belt 46 can always transfer between the two different systems with different intervals; two steering rollers 436 are rotatably arranged between the side plates 410, and the two steering rollers 436 can reverse the conveyor belt 46, and the steering roller 436 close to the movable plate 431 cooperates with the adjusting roller 435 to fold and hide a length of the conveyor belt 46, and when the third hydraulic rod 432 drives the movable plate to move along the fixed plate 430, the total length between the movable plate 431 and the fixed plate 430 changes. At this time, the conveyor belt 4 6 also needs to be deformed accordingly to ensure that the conveyor belt 46 can normally transport the ore. In this way, an L-shaped plate 434 connected to the movable plate 431 is arranged so that when the third hydraulic rod 432 drives the movable plate 431 along the fixed plate 430, the movable plate 431 can drive the L-shaped plate 434 to move synchronously, so that the movable plate 431 drives the adjusting roller 435 to move through the L-shaped plate 434, so that the adjusting roller 435 retracts and releases the conveyor belt 46, so that the length of the conveyor belt 46 can always be timely adapted to the total length of the fixed plate 430 and the movable plate 431, avoiding the situation that the conveyor belt 46 is difficult to adapt after the total length between the movable plate 431 and the fixed plate 430 changes; in addition, in order to ensure the normal transmission of the conveyor belt 46 and the conveyor roller 45, the conveyor belt 46 is limited and guided by setting a second limiting roller 433, so that the conveyor belt 46 and the conveyor roller 45 on the movable plate 431 are closely fitted, ensuring the normal transmission between the conveyor roller 45 and the conveyor belt 46.

[0054] In another embodiment provided by the present invention, the rotating mechanism 44 includes two adjusting motors 440, the output end of the adjusting motor 440 is provided with an adjusting gear 441, the end of the telescopic mechanism 43 away from the swing mechanism 42 is provided with a rotating plate 442 in a rotatable manner, the rotation center of the rotating plate 442 coincides with the rotation center of the conveying roller 45 on the telescopic mechanism 43, the end of the rotating plate 442 close to the telescopic mechanism 43 is provided with an engaging portion 443, the adjusting gear 441 is engaged with the engaging portion 443, and the end of the rotating plate 442 away from the telescopic mechanism 43 is provided with the conveying roller 45 in a rotatable manner;

[0055] The specific implementation method is as follows: during the use of the transfer machine 4, when the two different transportation systems connected to the transfer machine 4 are incompatible with each other in height, the rotation mechanism 44 of the transfer machine 4 is used to adjust the position of the rotating plate 442 away from one end of the moving plate 431 to be close to the lower transportation system, so that the conveyor belt 46 can accurately transfer the ore to the lower transportation system, avoiding the situation that the transportation system is strongly vibrated due to the height difference during the transfer process. Specifically, the adjusting motor 440 drives the adjusting gear 441 installed at its output end to rotate, so that the adjusting gear 441 drives the meshing part 440 meshing with it. 43 rotates, so that the meshing portion 443 drives the rotating plate 442 connected thereto to rotate on the moving plate 431, so that the rotating plate 442 adjusts the height of the conveying roller 45 thereon, so that the conveying roller 45 on the rotating plate 442 is as close as possible to the transportation system arranged at the rear thereof, so that the conveying roller 45 adjusts the conveyor belt 46 to be close to the transportation system arranged at the rear thereof, so that the conveyor belt 46 transfers the ore to the next transportation system as lightly as possible, and avoids the ore transported by the conveyor belt 46 at the rotating plate 442 from falling and hitting the next transportation system, thereby reducing the vibration of the next transportation system and extending the service life of the next transportation system.

[0056] Furthermore, a supporting plate is provided between the two rotating plates 442 and between the two swinging plates 420 , and the supporting plate is used to support and limit the conveyor belt 46 during transportation to prevent the conveyor belt 46 from being deformed due to load.

[0057] Working principle: When the transfer machine 4 is in use, the transfer machine 4 is moved to a designated position through the crawler assembly 3. Specifically, the driving member 20 drives the driving pulley 21 to rotate, so that the driving pulley 21 drives the first pulley 23 and the rotating shaft 22 to rotate, so that the first pulley 23 at the other end of the rotating shaft 22 drives the second pulley 25 to rotate, so that the second pulley 25 drives the driving shaft 24 to rotate, so that the driving shaft 24 drives the crawler assembly 3 to rotate and move. In this way, the crawler assembly 3 drives the transfer machine 4 to move to a designated position, which is convenient for the transfer machine 4 to transport two different The system is connected and transferred, and after the transfer machine 4 moves to the designated position, the driving member 20 stops rotating, and the first hydraulic rod 48 drives the mounting plate 40 to rise and fall through the angle bracket 49, so that the mounting plate 40 drives the transfer machine 4 to rise and fall, that is, the first hydraulic rod 48 adjusts the distance between the transfer machine 4 and the crawler assembly 3 through the angle plate and the mounting plate 40, so that the first hydraulic rod 48 and the angle bracket 49 adjust the transfer machine 4 to a suitable height position, so that the transfer machine 4 can be at different height positions according to different working environments, thereby improving the applicability of the transfer machine 4;

[0058] After the position of the transfer machine 4 is adjusted, when the transfer machine 4 is connected to two different transportation systems, the two different transportation systems may have a height difference. To adapt to this situation, the extended end of the second hydraulic rod 421 can be extended and retracted along its own central axis, so that the second hydraulic rod 421 drives the swing plate 420 connected thereto to rotate along the side plate 410, so that the second hydraulic rod 421 adjusts the swing plate 420 to a suitable position, ensuring that the conveyor belt 46 at the swing mechanism 42 can transport the ore at the most suitable position angle, and the swing plate 420 drives the conveying roller 45 installed thereon to rotate along the side plate 410. During rotation, in order to ensure that there is no large gap between the conveyor belt 46 and the conveyor roller 45, the conveyor belt 46 is limited and guided by setting a first limiting roller 422, so that the conveyor belt 46 and the conveyor roller 45 on the side plate 410 are closely fitted, ensuring the transmission between the conveyor roller 45 and the conveyor belt 46; and the cover plate 10 is used to support and support the transfer machine 4, and one end of the cover plate 10 is set as an inclined surface, so that the swing mechanism 42 can rotate and swing on the mounting mechanism 41, and the cover plate 10 can expand the swing range of the swing mechanism 42, avoiding the cover plate 10 limiting the swing angle of the swing mechanism 42;

[0059] In addition, when the transfer machine 4 is in use, when the two different transport systems connected to the transfer machine 4 are too far apart or too small, the two different transport systems may be spaced too far apart. To adapt to this situation, the third hydraulic rod 432 drives the movable plate 431 to move along the fixed plate 430, so that the total length between the movable plate 431 and the fixed plate 430 is changed in time according to the interval between the two different systems, so that the conveyor belt 46 can always transfer between the two different systems with different intervals; two steering rollers 436 are arranged between the side plates 410 in a rotatable manner, and the two steering rollers 436 can reverse the conveyor belt 46. The steering roller 436 close to the movable plate 431 cooperates with the adjusting roller 435 to fold and hide a length of the conveyor belt 46. When the third hydraulic rod 432 drives the movable plate to move along the fixed plate 430, the total length between the movable plate 431 and the fixed plate 430 changes. At this time, the conveyor belt 46 also needs to be deformed accordingly to ensure that the conveyor belt 46 can normally transport the ore. In this way, an L-shaped plate connected to the movable plate 431 is arranged 434, so that when the third hydraulic rod 432 drives the movable plate 431 along the fixed plate 430, the movable plate 431 can drive the L-shaped plate 434 to move synchronously, so that the movable plate 431 drives the adjusting roller 435 to move through the L-shaped plate 434, so that the adjusting roller 435 retracts and releases the conveyor belt 46, so that the length of the conveyor belt 46 can always be timely adapted to the total length of the fixed plate 430 and the movable plate 431, avoiding the situation that the conveyor belt 46 is difficult to adapt after the total length between the movable plate 431 and the fixed plate 430 changes. Specifically, when the distance between the two different transport systems is large, the third hydraulic rod 432 drives the movable plate 431 to move away from the fixed plate 430, so that the movable plate 431 drives the L-shaped plate 434 to move synchronously, so that the L-shaped plate 434 drives the adjusting roller 435 to move away from the swing mechanism 42. At this time, the adjusting roller 435 and the steering roller 436 can release the folded and hidden part of the conveyor belt 46. As the total length between the fixed plate 430 and the movable plate 431 increases, the leaking part of the conveyor belt 46 increases.When the distance between the two different transport systems is small, the third hydraulic rod 432 drives the movable plate 431 to move toward the fixed plate 430, so that the movable plate 431 drives the L-shaped plate 434 to move synchronously, so that the L-shaped plate 434 drives the adjusting roller 435 to move toward the swing mechanism 42. At this time, the adjusting roller 435 and the steering roller 436 further fold and hide the conveyor belt 46, and as the distance between the adjusting roller 435 and the reversing roller close to the rotating mechanism 44 increases, the conveyor belt 46 is folded and hidden. The longer the part, as the total length between the fixed plate 430 and the movable plate 431 becomes shorter, the exposed part of the conveyor belt 46 becomes shorter, so that the conveyor belt 46 can always adapt to the deformation between the fixed plate 430 and the movable plate 431. In addition, in order to ensure the normal transmission of the conveyor belt 46 and the conveyor roller 45, the second limiting roller 433 is provided to limit and guide the conveyor belt 46, so that the conveyor belt 46 and the conveyor roller 45 on the movable plate 431 fit closely, ensuring the normal transmission between the conveyor roller 45 and the conveyor belt 46;

[0060] When the transfer machine 4 is connected to two different transport systems, there may be a height difference between the two transport systems. In addition to the rotation and deformation of the swing mechanism 42, the rotating mechanism 44 can also be rotated to adjust and adapt to the height difference between the two transport systems. Specifically, the adjusting motor 440 drives the adjusting gear 441 installed at its output end to rotate, so that the adjusting gear 441 drives the meshing portion 443 engaged with it to rotate, so that the meshing portion 443 drives the rotating plate 442 connected to it to rotate on the moving plate 431, so that the rotating plate 442 adjusts the height of the conveying roller 45 thereon, so that the conveying roller 45 on the rotating plate 442 is as close as possible to the transport system set at the rear thereof, so that the conveying The roller 45 adjusts the conveyor belt 46 to be close to the transportation system arranged at the rear thereof, so that the conveyor belt 46 can transfer the ore to the next transportation system as lightly as possible, and avoid the ore transported by the conveyor belt 46 at the rotating plate 442 from falling and hitting the next transportation system, thereby reducing the vibration of the next transportation system and extending the service life of the next transportation system. In this way, it is convenient for the conveyor belt 46 to accurately transfer the ore to the lower transportation system, and avoid the situation where the transportation system is strongly vibrated due to the height difference during the transportation process; in addition, a support plate is arranged between the two rotating plates 442 and between the two swinging plates 420, and the support plate is used to support and limit the conveyor belt 46 during transportation, so as to avoid the load-bearing deformation of the conveyor belt 46.
