In addition, in order to further improve the sealing effect of the box body 2, an airtight structure is provided between the conveying roller and the sleeve hole 2.2, and an airtight seal is provided between the box door 3 and the door opening 2.1.

[0031] The filter box 6 is installed at the input end of the air pump 5 , and the input end of the filter box 6 is connected to the output end of the air extraction mechanism 8 .

[0032] The upper air shower mechanism 7 is arranged at the front and rear ends of the top of the inner cavity of the box body 2 and is used to blow air obliquely downward, wherein the upper air shower mechanism 7 comprises a main air outlet pipe 7.1 fixed to the top of the front and rear walls of the inner cavity of the box body 2 in the horizontal direction and a plurality of arc tubes 7.2 whose bottom ends are connected to the top surface of the main air outlet pipe 7.1, the inner peripheral wall of the arc tube 7.2 is provided with a plurality of air jet holes 7.2.1, and the outer wall of the main air outlet pipe 7.1 is connected with an air inlet pipe head 7.3 connected to the output end of the air pump 5. The top of the front and rear walls of the box body 2 is provided with a socket 2.4 that is sleeved and matched with the air inlet pipe head 7.3.

[0033] The air extraction mechanism 8 is respectively fixed to the middle of the front and rear walls of the inner cavity of the box body 2. The air extraction mechanism 8 comprises a strip box body 8.1 and an air extraction housing 8.2 connected to the inner end of the strip box body 8.1, the inner end surface of the air extraction housing 8.2 is provided with a plurality of suction holes 8.2.1, the front and rear walls of the box body 2 are respectively provided with strip grooves 2.3 in the horizontal direction for snap-fitting with the strip box body 8.1, and the top surface of the outer end of the strip box body 8.1 is provided with an exhaust hole 8.1.1 connected to the input end of the filter box 6.

[0034] The lower air shower mechanism 9 is arranged at the bottom of the inner cavity of the box body 2 and is used for blowing air upwards. Among them, a bottom groove 2.5 is opened in the middle of the bottom plate of the box body 2 along the conveying direction of the roller conveyor line 1, and the lower air shower mechanism 9 includes a fixed slat 9.1 fixed to the outer edge of the bottom groove 2.5, a lifting and telescopic cylinder 9.2 whose top end of the piston cylinder is fixed to the middle of the bottom surface of the fixed slat 9.1 and the piston rod passes through the fixed slat 9.1, a supporting slat 9.3 fixed to the top of the piston rod of the lifting and telescopic cylinder 9.2 in the middle of the bottom surface, a plate-shaped frame 9.4 fixed to the top surface of the supporting slat 9.3 and facing the gap between the conveying rollers, a U-shaped tube 9.5 fixed to the top surface of the plate-shaped frame 9.4 and an air inlet pipe head 9.6 connected to the input end of the air pump 5, a plurality of nozzles 9.5.1 are mounted on the U-shaped tube 9.5, and a hose 9.7 is connected to the inner end of the air inlet pipe head 9.6 and one end of the U-shaped tube 9.5 respectively, and a top column 9.4.1 higher than the nozzle 9.5.1 is fixed to the top surface of the plate-shaped frame 9.4 between the nozzles 9.5.1. The bottom of the front wall of the box body 2 is provided with a socket 2.4 that is sleeved and matched with the air inlet head 2 9.6.

[0035] In summary, the conveying roller on the roller conveyor line 1 conveys the goods from the door opening on one side to the inner cavity of the box body 2, and then the piston rod of the door panel telescopic cylinder 4 contracts, so that the box door 3 closes the door opening 2.1. The air pump 5 is turned on, and the air pump 5 inputs high-pressure airflow to the upper air shower mechanism 7 and the lower air shower mechanism 9 through the air inlet head 1 7.3 and the air inlet head 2 9.6 respectively. The airflow is sprayed onto the surface of the goods from the jet hole 7.2.1 and the nozzle 9.5.1 respectively, and the air carrying the blown-off dust enters the filter box 6 through the suction hole 8.2.1, the exhaust housing 8.2, the strip box body 8.1, and the filtered air enters the circulating air shower system.

[0036] At this time, the airflow sprayed by the nozzle 9.5.1 cannot blow off the dust on the bottom surface of the goods in contact with the conveying roller, so the lifting and telescopic cylinder 9.2 pushes up the supporting slats 9.3, so that the plate frame 9.4 together with the U-shaped tube 9.5 passes through the gaps between the corresponding conveying rollers, and the top column 9.4.1 lifts the goods to make the bottom surface of the goods separate from the conveying roller. At this time, the airflow sprayed by the nozzle 9.5.1 can cover the bottom surface of the goods that has not been air-showered in the early stage, thereby achieving the effect of all-round air-showering of the goods.

[0037] In addition, the airflows ejected by the nozzle 9.5.1 and the air jet holes 7.2.1 are diffuse radial to ensure all-round air shower treatment of the cargo surface.
