The transport mechanism 20 is disposed on the base 10, the buffer mechanism 30 is disposed between the base 10 and the transport mechanism 20, the buffer mechanism 30 has a stop position and a first avoiding position that are disposed opposite to each other, and when the buffer mechanism 30 is disposed at the stop position, the buffer mechanism 30 can limit the relative displacement between the transport mechanism 20 and the base 10. The locking mechanism 40 is disposed between the base 10 and the transport mechanism 20, the locking mechanism 40 having a locking position and a second retracted position disposed opposite one another, the locking mechanism 40 being capable of limiting the relative position of the transport mechanism 20 to the base 10 when the locking mechanism 40 is in the locking position. Wherein, when the transport mechanism 20 is at the initial position, the buffer mechanism 30 is at the stop position, and the locking mechanism 40 is at the second avoiding position, so that the transport mechanism 20 can be positioned by the buffer mechanism 30; when the transport mechanism 20 is displaced relative to the base 10, the buffer mechanism 30 is switched between a stop position and a first avoiding position so as to stop and buffer the transport mechanism 20; when the movement of the transport mechanism 20 relative to the base 10 reaches a predetermined value, the locking mechanism 40 is in a locked position to limit the movement of the transport mechanism 20. In particular, in the present application, the buffer mechanism 30 and the locking mechanism 40 are used to restrict the displacement of the transport mechanism 20 in the horizontal plane perpendicular to the transport direction of the transport mechanism 20, that is, the displacement of the transport mechanism 20 in the left-right direction with respect to the base 10 in fig. 1.

With the above structure, when the transport mechanism 20 receives the impact generated by blasting, the transport mechanism 20 is displaced relative to the base 10, and the buffer mechanism 30 and the locking mechanism 40 can buffer the transport mechanism 20, so that the impact received by the transport mechanism 20 can be reduced, and the transport mechanism 20 can be prevented from being damaged. In addition, the buffer mechanism 30 can play a role in buffering the movement of the transport mechanism 20, so that the transport mechanism 20 is prevented from moving too fast to influence the normal operation of the transport mechanism 20, and the transport mechanism 20 is prevented from being damaged secondarily. Meanwhile, the locking mechanism 40 can timely limit the movement of the conveying mechanism 20, so that the condition that the conveying mechanism 20 shakes left and right in the moving process is avoided, the normal operation of the conveying mechanism 20 is further ensured, and broken stones are prevented from falling from the conveying mechanism 20 due to inertia.

Further, the conveying device further comprises a linkage structure, wherein the linkage structure is arranged between the buffer mechanism 30 and the locking mechanism 40, and the linkage structure is used for enabling the buffer mechanism 30 to switch from the second avoidance position to the locking position by switching between the stop position and the first avoidance position so as to drive the locking mechanism 40. By adopting the linkage structure, the relevance between the buffer mechanism 30 and the locking mechanism 40 can be enhanced, when the buffer mechanism 30 is switched between the stop position and the first avoiding position, the locking mechanism 40 can correspondingly switch between the second avoiding position and the locking position, and the motion of the locking mechanism 40 can not generate hysteresis, so that the locking effect of the locking mechanism 40 can be ensured, and the mechanism can conveniently realize motion and structural functions.

The buffer mechanism 30 occupies a small space, and the buffer and stop effects of the buffer mechanism 30 can be ensured. Specifically, in the present application, by providing the limiting groove 31, when the transport mechanism 20 moves relative to the base 10, the limiting groove 31 can be utilized to move relative to the telescopic assembly 32, so as to drive the telescopic assembly 32 to switch between the stop position and the first avoiding position, thereby realizing that the buffer mechanism 30 buffers and stops the transport mechanism 20.

The positioning member 41 can be switched between the separation from and the attachment to the transport mechanism 20, thereby enabling the lock mechanism 40 to be switched between the second retracted position and the lock position. When the positioning piece 41 is attached to the conveying mechanism 20, friction between the conveying mechanism 20 and the positioning piece 41 can be improved, so that the moving mechanism is locked, and the positioning piece is simple in structure and convenient to operate.

As shown in fig. 2, in the present embodiment, the linkage structure is a pneumatic structure, and the linkage structure includes a flow passage 51, an inflation hole 52, a control valve 53, and an airbag 54.

When the transport mechanism 20 moves relative to the base 10, the gas can flow from the communication port to the air charging port 52 through the first through hole 5311 and the second through hole 5312, and meanwhile, the sealing piece 532 can limit the flow of the gas from the air charging port 52 to the communication port, so that the gas can flow into the air bag 54, and the locking effect of the locking mechanism can be ensured. The air in the air bag 54 and the inflation hole 52 flows to and from the communication port through the first through hole 5311, so that the lock mechanism is switched to the second avoidance position, at which time the transport mechanism 20 is restored to the initial position. The device has the advantages that the structure for controlling the flow direction of the gas is simple, and the device is convenient to implement and operate. Wherein, the second through hole 5312 may be disposed at the center of the body 531, and the first through hole 5311 is annularly surrounded on the outer side of the second through hole 5312.
