Sliding friction between the goods 200 and the loading plate body 56211 is converted into rolling friction by the plurality of first rollers 56212, so that resistance generated by friction between the goods 200 and the first loading plate 5621 is greatly reduced, the goods 200 fall from the first loading plate 5621 to the transmission mechanism 53, and unloading efficiency of the unloader 5 is improved.

As shown in fig. 19, since the first carrying assembly 562 has a limited area and angle for carrying the cargo 200, a part of the cargo 200 is not dropped directly onto the transferring mechanism 53 via the buffering mechanism 56, which is likely to cause damage to the cargo 200. In order to solve the above problem, the buffering mechanism 56 further includes a second carrying assembly 563, the second carrying assembly 563 is pivotally connected to the first carrying assembly 562, and the first carrying assembly 562 and the second carrying assembly 563 cooperate to enlarge the area for carrying the cargo 200, and can carry the cargo 200 from different angles.

Preferably, as shown in fig. 19, the buffer mechanism 56 further includes a buffer member 565, the buffer member 565 is disposed between the first bearing assembly 562 and the second bearing assembly 563, the buffer member 565 is used for buffering the second bearing assembly 563, and when the cargo 200 falls on the second bearing assembly 563, the buffer member 565 provides buffer for the second bearing assembly 563 to relieve rigid collision between the cargo 200 and the second bearing assembly 563. Illustratively, the cushioning member 565 is preferably a nitrogen spring that can passively contract when a force is applied thereto and automatically return to an initial position when the external force is released. Meanwhile, the nitrogen spring is simple in structure and convenient to assemble and maintain by an operator. It will be appreciated that in order for the second carrier assembly 563 to receive as much cargo 200 as possible, the second carrier assembly 563 is angled at an obtuse angle to the first carrier assembly 562.

Specifically, the structure of the second bearing assembly 563 is described with reference to fig. 19, 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 pivotally connected 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 the upper surface of the second bearing plate 5631 and pivotally connected to the second bearing plate 5631. A plurality of second gyro wheels 5632 turn into rolling friction with the sliding friction between goods 200 and the second loading board 5631 to reduce substantially the resistance that produces because of the friction between goods 200 and the second loading board 5631, more be favorable to goods 200 to drop to transmission device 53 from the second loading board 5631 on, and then be favorable to improving the discharge efficiency of unloader 5.

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

As shown in fig. 1 and 11, the operator first hooks the hook 55 to the loop of the transfer device 6, opens the truck 400 to a position facing the unloader 5, and the body 401 and the first frame 402 form a cargo space with an entrance facing the unloader 5. Next, the operator butt-joints the free end of the first mop 32 with the free end of the second mop 571 by means of the hook and loop fastener.

As shown in fig. 10, the motor 5731 is operated, and the motor 5731 can effect rotation of the first roller 572 through the transmission action of the rotation shaft 5733, the transmission wheel 5734, and the transmission belt 5735. As shown in fig. 9, the first roller 572 can roll the second mop 571 and the first mop 32 gradually, thereby enabling the effect that the unloader 5 gets closer to the first frame 402.

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 pointed inserting portion 5111 is first inserted into the lower portion of the outermost and bottommost cargo 200, and the lower portion of the cargo 200 to be the outermost and bottommost cargo is brought into contact with the first transfer mechanism 53 located on the front side, and the unloader 5 is halted at this position, and the outermost and bottommost cargo 200 is sequentially transferred onto the transfer device 6 by the operation of the transfer mechanism 53.

Next, the load 200 positioned in the outermost row and on the second to last floor falls on the first transfer mechanism 53 positioned on the front side by gravity and is sequentially transferred to the transfer device 6 by the first transfer mechanism 53 positioned on the front side. This continues so that the goods 200 in the outermost row can be transferred to the transfer device 6 by the transfer mechanism 53.

Certainly, because the goods 200 on the high level can happen accidental falling when falling layer by layer, the goods 200 falling from the higher position directly smashes on the transmission mechanism 53, which will result in the damage of the goods 200 or the transmission device 53, in order to solve the above problems, as shown in fig. 9, the buffer mechanism 56 above the transmission device 53 can buffer the goods 200 on the high level, the kinetic energy of the goods 200 falling from the buffer mechanism 56 to the transmission mechanism 53 is greatly reduced, and thereby the probability of the damage of the goods 200 or the transmission device 53 is effectively reduced.

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