Illustratively, the driving roller 53112 is preferably an electric roller, and the electric roller can be self-driven, so that the power of the conveyor 5311 for conveying the goods 200 is derived from the electric roller, and no additional driving structure is needed, thereby simplifying the structure of the conveyor 5311.

Referring to fig. 17, as an alternative, a chute along the conveying direction of the cargo 200 is formed on the upper end surface of the supporting plate 531112, and a guiding rib 531141 extending along the circumferential direction of the annular belt 53114 is disposed on the inner circumferential surface of the annular belt 53114, and the guiding rib 531141 is inserted into the chute and slides along the chute.

In the prior art, the stack of the cargos 200 is higher, all the cargos 200 to be unloaded directly fall on the conveying mechanism 53, and if the cargos 200 at the higher position directly fall on the conveying mechanism 53, a larger impact force is easily generated with the conveying mechanism 53, so that the cargos 200 falling at the higher position are damaged.

In order to solve the above problem, as shown in fig. 18, the unloader 5 in this embodiment further includes a buffer mechanism 56, where the buffer mechanism 56 is disposed on the main body 51 and is located above the transmission mechanism 53, and the goods 200 falling from a high place can first fall on the buffer mechanism 56, so as to achieve a buffer protection effect on the goods 200 falling from a high place, avoid damage to the goods 200 falling from a high place, reduce the probability of damage caused by the goods 200 falling directly from a high place onto the transmission mechanism 53, and facilitate improvement of safety in the working process of the unloader 5.

As shown in fig. 18 and 19, the buffer mechanism 56 further includes an adjusting mechanism 564, where the first bearing component 562 is pivoted with the first mounting frame 561, and the adjusting mechanism 564 can drive the first bearing component 562 to rotate relative to the first mounting frame 561, so as to adjust the height of the first bearing component 562, thereby adjusting the heights of the first bearing component 562, and further achieving the buffer effect on the cargos 200 with different heights. For example, the height of the first bearing assembly 562 can be adjusted according to different heights of the cargos 200, and can also be adjusted according to different discharging progress, so that the buffer mechanism 56 has wider application range and application field.

The structure of first carrier assembly 562 is described in connection with fig. 19, and first carrier assembly 562 includes mounting plate 566, first carrier plate 5621, and buffer 5622 as shown in fig. 19. The mounting plate 566 is pivotally connected to the first mounting frame 561, and the first carrying plate 5621 is located above the mounting plate 566 and is used for receiving the goods 200 falling from a high place. The buffer 5622 is disposed between the mounting plate 566 and the first bearing plate 5621, when the cargo 200 collides with the first bearing plate 5621, the buffer 5622 plays a role in buffering the first bearing plate 5621, the buffer 5622 can absorb impact force of the cargo 200, and rigid contact force between the cargo 200 and the first bearing plate 5621 is reduced, so that damage to the cargo 200 is avoided. Illustratively, the cushioning member 5622 is preferably a spring that provides a good cushioning effect while being a conventional component that is inexpensive and easy to purchase. As a preferable embodiment, as shown in fig. 19, a plurality of cushioning members 5622 are provided, and the plurality of cushioning members 5622 are arranged in an array manner, so that the impact force at each position of the first carrier plate 5621 can be absorbed.

Further, referring to fig. 19, the first bearing assembly 562 further includes a guide assembly 5623, where the first bearing plate 5621 is connected to the mounting plate 566 via the guide assembly 5623, and the guide assembly 5623 is configured to provide guidance to the first bearing plate 5621, so that the first bearing plate 5621 can move in a direction approaching or separating from the mounting plate 566, thereby better compression of the first bearing plate 5621 on the buffer member 5622 is achieved, and better buffering effect of the buffer member 5622 on the first bearing plate 5621 is achieved.

Optionally, as shown in fig. 19, the guide assembly 5623 includes a guide rod 56231 and a guide sleeve 56232.

As shown in fig. 19, the first bearing assembly 562 is capable of bearing the cargo 200 with a limited area and angle, so that a part of the cargo 200 directly falls on the conveying mechanism 53 without passing through the buffer mechanism 56, which is easy to damage the cargo 200. In order to solve the above problem, the buffer mechanism 56 further includes a second carrying component 563, where the second carrying component 563 is pivotally connected to the first carrying component 562, and the first carrying component 562 and the second carrying component 563 cooperate to enlarge the area for receiving the cargo 200, and can receive the cargo 200 from different angles.

Preferably, as shown in fig. 19, the buffering mechanism 56 further includes a buffering component 565, where the buffering component 565 is disposed between the first bearing component 562 and the second bearing component 563, and the buffering component 565 is configured to buffer the second bearing component 563, and when the cargo 200 falls on the second bearing component 563, the buffering component 565 provides buffering for the second bearing component 563, so as to alleviate a rigid collision between the cargo 200 and the second bearing component 563. Illustratively, the cushioning component 565 is preferably a nitrogen spring that is capable of passively contracting under force and automatically returning to an original position upon release of an external force. Meanwhile, the nitrogen spring is simple in structure and convenient for operators to assemble and maintain. It will be appreciated that in order for the second carrier member 563 to receive as much of the cargo 200 as possible, the second carrier member 563 forms an obtuse angle with the first carrier member 562.

Specifically, referring to fig. 19, the structure of the second bearing assembly 563 is described, as shown in fig. 19, the second bearing assembly 563 includes a second bearing plate 5631 and a plurality of second rollers 5632, the second bearing plate 5631 is pivoted to the first bearing assembly 562, the plurality of second rollers 5632 are arranged in a matrix, and the plurality of second rollers 5632 are located on an upper surface of the second bearing plate 5631 and are pivoted to the second bearing plate 5631. The plurality of second rollers 5632 convert sliding friction between the cargo 200 and the second carrier plate 5631 into rolling friction, thereby greatly reducing resistance generated between the cargo 200 and the second carrier plate 5631 due to friction, being more beneficial to dropping the cargo 200 from the second carrier plate 5631 onto the transmission mechanism 53, and further being beneficial to improving unloading efficiency of the unloader 5.

The principle of operation of the discharge system 100 will be described with reference to fig. 1, 9, 10 and 11.

As shown in fig. 1 and 11, the operator first hangs the hanger 55 on the conveyor 6, and opens the wagon 400 to a position facing the unloader 5, and the entrance of the cargo space formed by the wagon body 401 and the first frame 402 is facing the unloader 5. Next, the operator interfaces the free end of the first backing 32 with the free end of the second backing 571 by means of velcro.

As shown in fig. 10, the motor 5731 is operated, and the motor 5731 can rotate the first roller 572 through the transmission action of the rotating shaft 5733, the transmission wheel 5734, and the transmission belt 5735. As shown in fig. 9, the first roller 572 can gradually wind up the second cloth 571 and the first cloth 32, so that the effect that the unloader 5 gradually approaches the first frame 402 can be achieved.

As the unloader 5 moves, the unloader 5 gradually moves toward the inside of the vehicle body 401, and as shown in fig. 9, the insertion portion 5111 in the form of a pointed shape is first inserted into the lower portion of the outermost and bottommost cargo 200, and the lower portion of the cargo 200 to be brought into contact with the first conveying mechanism 53 located on the front side is brought into contact with the unloader 5, and at this position, the outermost and bottommost cargo 200 is successively conveyed onto the conveying means 6 by the operation of the conveying mechanism 53.

Next, the cargo 200 located in the outermost row and the penultimate layer falls on the first transporting mechanism 53 located on the front side due to gravity and is transported successively toward the transporting device 6 by the first transporting mechanism 53 located on the front side. In this manner, the cargo 200 located in the outermost row can be transferred to the transfer device 6 by the transfer mechanism 53.

Of course, since the high-rise cargo 200 may fall accidentally when falling layer by layer, the falling cargo 200 at a higher position directly falls on the transmission mechanism 53, which may cause damage to the cargo 200 or the transmission device 53, in order to solve the above problem, as shown in fig. 9, the buffer mechanism 56 located above the transmission device 53 may perform a certain buffer function on the high-rise cargo 200, and the kinetic energy of the cargo 200 falling from the buffer mechanism 56 to the transmission mechanism 53 is greatly reduced, thereby effectively reducing the probability of damage to the cargo 200 or the transmission device 53.

Then, after the outermost layer of goods 200 is taken out, the unloader 5 continues to move forward, and then the second layer of goods 200, the third layer of goods 200 and other layers of goods 200 from outside to inside can be sequentially transferred to the transfer device 6 by the unloader 5.
