[0042] In the embodiment 3, when the bulk cargo is transported in the material disc 4, as the material disc 4 loads the bulk cargo and is placed on the conveying belt 3, during the rotation of the above-mentioned adsorption adjusting part 10, the cam 11 is driven to rotate, so that the cam 11 rotates and intermittently pushes the vibration generating part 12 above, through the up-down vibration of the carrier plate 121 in the vibration generating part 12, the vibration of the top bulk cargo is uniformly carried out, avoiding local accumulation, and after being conveyed out between the magnetic plate three 55, as the magnetic induction starting piece 8 resets, the adsorption adjusting part 10 flips and resets, at the same time, the cam 11 automatically carries out secondary vibration processing, completing the material uniformization processing during conveying.

[0043] Firstly, through the induction control of the magnetic induction starting part 8 and the magnetic control assembly 5 again, the starting action of the adsorption adjusting part 10 is realized, and the negative pressure adsorption fixing of the tray 4 and the conveying belt 3 is completed, along with the rotating action of the adsorption adjusting part 10, the cam 11 matched and installed and the vibration generating part 12 built-in in the tray 4, the continuous vibration of the vibration generating part 12 is realized synchronously, for the conveying of bulk goods, the reciprocating vibration of the vibration generating part 12 in the tray 4 can be realized, the bulk goods are uniformly treated by vibration, local accumulation is avoided, and the conveying effect is further improved, and the goods are optimally treated during conveying.

[0044] The stable conveying mechanism is a magnetic attraction fixing part, which comprises an electromagnet 13 and a metal wire pre-buried on the outer side of the conveying belt 3. When the switch part 82 of the magnetic induction starting part 8 senses pressure, the electromagnet 13 is electrified and generates magnetism, and the electromagnet 13 is magnetically attracted and fixed on the conveying belt 3 through the metal wire on the conveying belt 3.

[0045] The specific metal wire is a metal wire that can be magnetically attracted, uniformly distributed on the outer side of the conveying belt 3, and fixed by pre-buried fixing or the like. The magnetic attraction fixing is completed through the magnetic attraction action.

The switch part 82 is a pressure-sensitive starting part, which is electrified to generate magnetism when sensing pressure, and the electromagnet 13 on the bottom of the tray 4 is magnetically attracted and fixed on the outer side of the conveying belt 3 through the metal wire pre-buried on the outer side of the conveying belt 3, and follows the conveying belt to stably transport. When the tray 4 moves out from between the magnetic plates three 55 in the magnetic control assembly 5 on the two sides, the magnetic plates four 81 in the magnetic induction starting part 8 are elastically reset through the spring one 84, and are separated from the switch part 82.
