[0037] Referring to Figures 1-8 , in order to better show the working process of the bulk blank recycling system of the V-belt conveyor, the bulk blank recycling system of the V-belt conveyor is provided in this embodiment, which comprises the following steps:

[0038] S101: The bulk material falls into the blank receiving device 22 from the V-belt conveyor 1. The bulk blank is divided into streams through the blank dividing pipe 23. When the amount of bulk blank is small, the blank blocking device 241 closes the outlet of the blank dividing pipe 23. The bulk blank flows out from a small number of outlets of the blank dividing pipe 23 and enters a small number of bulk blank collecting barrels 21. When the amount of bulk blank is large, the blank blocking device 241 opens the outlet of the blank dividing pipe 23. The bulk blank flows out from a large number of outlets of the blank dividing pipe 23 and enters a large number of bulk blank collecting barrels 21.

[0039] S102: The bulk blank is collected in the bulk blank collecting barrel 21. The bulk blank collecting barrel 21 is moved into the blank collecting barrel conveying device 4 by the blank transferring device 3. The bulk blank collecting barrel 21 is transported to the blank collecting barrel lifting and dumping device 5 by the blank collecting barrel conveying device 4. Finally, the bulk blank collecting barrel 21 is slowed down and parked above the transmission roller assembly 533 in the blank collecting barrel lifting and dumping device 5.

[0040] S103: The double-rod cylinder 532 pushes the bulk material collecting barrel clamping device 531 to constrain the position of the bulk material collecting barrel 21, the transmission assembly 57 provides power, the bulk material collecting barrel 21 rises along the linear track of the lifting guide rail 52 with the lifting platform assembly 53, is lifted to the height of the V-belt conveyor 1, is rotated along the curved track of the lifting guide rail 52 and abuts with the receiving platform 56, the bulk material in the bulk material collecting barrel 21 is poured onto the receiving platform 56 and slides into the V-belt conveyor 1 through the receiving platform 56;

[0041] S104: After the bulk material is recycled, the bulk material collecting barrel 21 is returned to the original position along with the lifting platform assembly 53, and the bulk material collecting barrel 21 is placed under the outlet of the material distribution pipe 23 by manual operation.

[0042] In step S103, when the lifting platform assembly 53 rotates and abuts with the receiving platform 56, the maximum rotation angle is 120°.

[0043] In summary: the added bulk material collecting device in the device of the embodiment can effectively prevent the bulk material from falling to the ground; the added bulk material transfer device can automatically position and grasp the bulk material collecting barrel; the added bulk material collecting barrel conveying device can store and transport the bulk material to the bulk material collecting barrel lifting and pouring device; the added bulk material collecting barrel lifting and pouring device can constrain the position of the bulk material collecting barrel through the bulk material collecting barrel clamping device, lift to a certain height and pour the bulk material into the V-belt conveyor. The bulk material recycling system makes the whole coal mine transportation process more automatic, avoids the bulk material from falling to the ground, greatly reduces the cost and risk of manual recycling of bulk material, and improves the efficiency and safety of the bulk material recycling process.
