[0046] A specific application of this embodiment is as follows: the present application places the first piece of wood without dust removal in the filter box 104, and then drives the motor 202 to operate through an external power supply, so that the motor 202 drives the rotating rod 203 to rotate, so that the rotating rod 203 drives the rotating shaft 204 to rotate, and then the rotating shaft 204 drives the short rod 205 to rotate, so that the short rod 205 drives the connecting rod 206 to rotate, and then the connecting rod 206 drives the positioning rod 207 to move horizontally, so that the positioning rod 207 pushes the positioning block 208 to move horizontally, and then the positioning block 208 drives the impact hammer 210 to impact the filter box 104, so that the impact hammer 210 hits the filter box 104, so that The filter box 104 vibrates, thereby driving the wood inside to vibrate, so that the wood is vibrated to remove dust, and the dust is peeled off the wood to facilitate subsequent processing. When the rotating rod 203 rotates, the rotating rod 203 drives the half gear 311 thereon to rotate. Since the power of the motor 202 is set to 120V, the rotation speed of the rotating rod 203 to drive the half gear 311 to rotate is too fast. Therefore, when the half gear 311 rotates to drive the rack 305 to move, the speed of movement is guaranteed, so that the half gear 311 drives the rack 305 to move horizontally, and then the rack 305 drives the push rod 306 to move horizontally, so that the push rod 306 drives the connecting block 30 7 is displaced in the horizontal direction, so that the connecting block 307 drives the push plate A308 to displace in the horizontal direction, so as to achieve the effect of pushing the wood in the filter box 104, so as to facilitate the removal of the dust-removed wood from the filter box 104. At the same time, the wood in the filter box 104 is pushed by the push plate A308, so that it pushes the baffle plate 312 to rotate, so that the wood can slide smoothly on the guide plate 301, and then the baffle plate 312 is pushed by the wood, so that the baffle plate 312 rotates through the long rod 302, so that the baffle plate 312 pushes the inclined block 404, so that the inclined block 404 is displaced in the vertical direction, so that the inclined block 404 pushes the slider 406 to displace in the horizontal direction, so that the slider 406 squeezes the rubber rod 408, As a result, the rubber rod 408 slides in the U-shaped groove 407, and the rubber rod 408 pushes the push plate B409, so that the push plate B409 pushes the remaining undusted wood inside the positioning frame 401, thereby achieving the effect of automatic feeding, which is convenient for pushing the undusted wood into the filter box 104. When the baffle 312 is closed with the filter box 104 through the torsion spring 303, that is, when the baffle 312 is away from the inclined block 404, the inclined block 404 is not subjected to force and thus falls, thereby causing the inclined block 404 to drive the slider 406 to reset through the connecting rope 410, and the slider 406 drives the rubber rod 408 to reset through the connecting rope 410, and the rubber rod 408 drives the push plate B409 to reset, thereby achieving the effect of automatic feeding.
