[0002] The bucket wheel stacker reclaimer is widely used in the bulk cargo yard of the port wharf, the mine yard, the power plant yard and the like, and is used for the bulk material stacking and taking. During the taking operation, after the bucket wheel stacker reclaimer takes the material of the first layer at the high position of the material pile through the slewing jib, the jib is lowered to reduce the distance between the bucket wheel and the ground of the yard, and then the taking operation of the material of the next layer is carried out. Due to the inconsistent settlement of different positions of the yard, after being used for a period of time, the yard is no longer a horizontal plane, and when the bucket wheel stacker reclaimer digs the material close to the ground of the yard, the hardened ground of the yard will be inevitably dug.

[0028] In order to solve the problem that the elastic buffer block in the coupling mechanism on the flexible hopper is made of rubber block, the rubber block will produce creep after being extruded for many times, the volume of the rubber block will be reduced, and the buffering effect of the coupling mechanism is reduced. The scheme provides a coupling mechanism and a flexible hopper, which can prolong the service life of the coupling mechanism, and ensure that the coupling mechanism can have good buffering effect when the hopper abuts against the hardened ground or the hardened and consolidated material pile in the long-term use of the flexible hopper.
[0029] Please refer to Figures 1-7 , Figures 1-7 In an embodiment of the utility model, a coupling mechanism comprises a mounting unit 1 and a buffer unit 2, the mounting unit 1 comprises a shaft body 11 and a plurality of limiting parts 12, the plurality of limiting parts 12 are all installed on the shaft body 11; the buffer unit 2 comprises a cylinder body 21, a moving piece 22 and an elastic piece 23, the cylinder body 21 is rotationally sleeved on the shaft body 11, a plurality of pushing parts 211 are arranged in the cylinder body 21, the moving piece 22 is arranged in the cylinder body 21 and is slidably sleeved on the shaft body 11, the moving piece 22 is provided with a plurality of transmission parts 221, the elastic piece 23 is arranged in the cylinder body 21 and abuts against the moving piece 22, one side of any transmission part 221 abuts against the limiting part 12, and the other side abuts against the pushing part 211, the cylinder body 21 can drive the moving piece 22 to slide relative to the cylinder body 21 and extrude the elastic piece 23 by rotating around the shaft body 11, and the pushing part 211 can abut against or separate from the limiting part 12.
[0030] It should be noted that in an embodiment, the moving part 22 comprises a ring block 220 which is slidingly arranged in the barrel 21 and sleeved on the shaft 11, one end surface of the ring block 220 is provided with a plurality of transmission parts 221, and the other end surface of the ring block 220 abuts against the elastic part 23.
[0031] It can be understood that when the hopper accidentally digs into the hardened ground or the hardened and compacted material pile of the yard, the barrel 21 can be driven to rotate around the shaft 11 in the retraction process, so as to drive the ring block 220 to slide relative to the barrel 21 and press the elastic part 23, so that the elastic part 23 is elastically deformed, thereby buffering the hopper in the retraction process, wherein the elastic part 23 is a return spring.
[0032] It should be noted that in an embodiment, three pushing parts 211 are arranged at intervals in the barrel 21, three limiting parts 12 are mounted on the shaft 11 at intervals, and one end surface of the ring block 220 is provided with three transmission parts 221, when the elastic part 23 is not subjected to external force, one side of any transmission part 221 abuts against the limiting part 12, and the other side abuts against the pushing part 211; when the elastic part 23 is subjected to external force, the pushing part 211 can push the ring block 220 to slide relative to the barrel 21 until the pushing part 211 abuts against the limiting part 12.

[0035] It can be understood that when the flexible hopper is working, the weight of the hopper and the material is less than the pre-tightening force of the elastic part 23 in the initial state, that is, the pushing force of the pushing part 211 is less than the initial pre-tightening force of the elastic part 23, the hopper remains in an open state, and performs material taking like a conventional rigid hopper, when the hopper touches the ground or the compacted and large block material, the external force is large enough, so that the coupling mechanism starts to work, realizing the function of flexible retraction of the hopper.

[0045] Need to be explained, by the limiting stop 321 arranged in the corresponding limiting groove, the limit position of the flexible rotation of the hopper 32 can be limited. Specifically, when the hopper 32 is assembled with the wheel body 31, the limiting stop 321 of the hopper 32 is just located between the outward limiting block and the retraction limiting block, so that the hopper 32 can only rotate between two limiting positions, and the function of the coupling mechanism is to realize the flexible coupling function within the rotation stroke.
