[0062] Figure 4 A schematic diagram of the structure of the dust removal mechanism according to an embodiment of the present invention; Figure 5 This is a disassembled diagram of the dust removal mechanism described in an embodiment of the present invention.

[0063] For example, Figure 4 and 5 As shown, the dust removal mechanism 23 includes a slide seat 231, a slide rod 232, a first motor 233, a rotating wheel 234, a rotating rod 235, a connecting portion, a swing rod 238 and a blowing nozzle;

[0064] The slide bar 232 is fixedly arranged on the cover plate 22, and the slide bar 232 is parallel to the length extension direction of the dust removal slit 221; the slide seat 231 is slidably arranged on the slide bar 232, the first motor 233 is fixedly arranged on the slide seat 231, and the rotating wheel 234 is connected to the first motor 233; one end of the rotating rod 235 is eccentrically arranged on the rotating wheel 234, and the other end is hinged to the connecting part, and the connecting part is also hinged to one end of the swing rod 238, and the middle part of the swing rod 238 is hinged to the slide seat 231; the nozzle is fixed to the other end of the swing rod 238, and the nozzle extends into the dust removal slit 221, and the nozzle is connected to the blowing device; the cover plate 22 is also provided with a fourth cylinder for controlling the movement of the slide seat 231; the first motor 233 and the fourth cylinder are both controlled by the controller.

[0065] Specifically, the connecting part includes a first connecting rod 236 and a second connecting rod 237, the first connecting rod 236 is perpendicular to the second connecting rod 237 to form a T-shaped structure, and the first connecting rod 236 is connected to the left side of the second connecting rod 237; the first connecting rod 236 is hinged to the rotating rod 235, and the two ends of the second connecting rod 237 are hinged with a swing rod 238; the sliding seat 231 is also fixedly connected to a door-shaped connecting ear 239, and the middle part of the swing rod 238 is hinged to the vertical sections on both sides of the connecting ear 239.

[0066] During dust removal, the controller controls the first motor 233 to operate and drives the rotating wheel 234 to rotate. The rotating rod 235 rotates with the rotating wheel 234.

The two support plates 275 are respectively connected to the top ends of the two lifting screws 274. The two ends of the support rod 277 are respectively fixed on the two support plates 275. The support rod 277 is provided with two clamping plates 276 for clamping the lunch box, one of the clamping plates 276 is fixed on the support rod 277, and the other clamping plate 276 is slidably arranged on the support rod 277 to facilitate the adjustment of the distance between the two clamping plates 276; the clamping plates 276 are provided with blocking rods 278 on both sides to cover the lunch box to prevent the lunch box from falling, and the blocking rods 278 are fixed on the side walls of the dust removal bin 26.

[0070] Specifically, the support rod 277 may be a door-shaped frame.
