The tops of the two clamps 3 are each welded with a connecting plate 44. The ends of the two push plates 43 away from the pusher 42 are rotatably connected to the two connecting plates 44 respectively.

[0026] In this system, the telescopic cylinder 41 extends, the pusher 42 descends vertically, causing the two push plates 43 to gradually become horizontal, and the two clamps 3 can be pushed to move closer to each other and rotate to grab the goods.

[0027] Preferably, the first vacuuming assembly 8 includes a first delivery pipe 81 and two first vacuum nozzles 82. The two first vacuum nozzles 82 are respectively fixedly installed on the bottom of the two clamps 3. One end of the first delivery pipe 81 is fixedly connected to the collection box 5, and the other end of the first delivery pipe 81 is connected to the first vacuum nozzles 82.

[0028] Preferably, the first delivery pipe 81 is a three-way pipe, the suction ports of the two first suction nozzles 82 are arranged facing each other, and the height of the first delivery pipe 81 at the connection point with the collection box 5 is lower than the height of the filter screen 7.

[0029] Preferably, the second dust collection component 9 includes a second delivery pipe 91 and a second dust collection nozzle 92. The second dust collection nozzle 92 is fixedly installed on the side of the housing cover 1.

[0031] Specifically, the negative pressure pump 6 creates negative pressure inside the collection box 5, causing dust on the bottom surface of the goods to be sucked in by the first suction nozzle 82 and transported to the collection box 5 through the first conveying pipe 81. Similarly, the second suction nozzle 92 sucks in dust on the top surface of the goods into the collection box 5, thus completing the dust collection and treatment of the goods surface, reducing dust generation. At the same time, the dust on the goods surface can be recycled and treated to avoid waste.

[0032] Preferably, a striking assembly 10 is provided on the push frame 42. The striking assembly 10 includes a striking frame 101. One side of the striking frame 101 is fixedly installed on the push frame 42. An eccentric shaft 102 is rotatably connected to the side of the striking frame 101 away from the push frame 42.

[0036] During the handling of goods, the telescopic cylinder 41 is extended first, so that the two clamps 3 grab the goods. Then, the negative pressure pump 6 is started to generate negative pressure in the collection box 5, so that the dust on the surface of the goods is sucked into the collection box 5 through the first conveying pipe 81 and the second conveying pipe 91, thus completing the dust collection treatment on the surface of the goods.

[0037] Furthermore, during the dust collection process, the motor 103 can be started to drive the eccentric shaft 102 to rotate, which in turn drives the beater 106 to beat the packaging bag up and down, causing the surface of the packaging bag to vibrate and loosen the firmly adhered dust, making it easier for the dust to be fully sucked into the collection box 5 for collection.
