[0030] Combination Figure 4 As shown, as a preferred structure, a movable groove 21 is opened on the inner surface of the bottom plate of the unloading channel, a rubber plate 10 is provided on the upper cover of the movable groove, a movable plate 11 is arranged in the movable groove, a plurality of ventilation pipes 14 are inserted into the unloading channel, one end of the ventilation pipe is connected to the movable groove, and the other end of the ventilation pipe is connected to the air compressor 18, the air compressor is used to output compressed gas, the air compressor is electrically connected to the timing switch 12, the ventilation pipe is used to introduce compressed gas into the movable groove, an air outlet 22 connected to the outside of the unloading channel is opened on the inner surface of the movable groove, a plurality of hemispherical protrusions 111 are provided on one side surface of the movable plate, the protrusions can generate contact vibrations to the rubber plate as the movable plate moves, a plurality of plugs 112 are provided on the other side surface of the movable plate, a plurality of inserts 13 for inserting the plugs are formed on the bottom surface of the movable groove, a spring 20 is also connected in the plug, and one end of the spring is connected to the plug.

[0031] The vent pipe is connected to the air compressor, and the air compressor introduces compressed gas into the movable groove through the vent pipe. Under the action of the compressed gas, the movable plate moves toward the notch of the movable groove, the spring stretches, and the protrusion on the movable plate produces contact vibration on the rubber plate. After the movable plate passes through the air outlet, the compressed gas in the movable groove is discharged from the air outlet. After the air compressor works for a certain period of time, the timer switch controls the air compressor to turn off, the air pressure in the movable groove gradually decreases, the spring begins to contract, and pulls the movable plate toward the bottom of the movable groove. After a period of time, the timer switch controls the air compressor to turn on again, and the air compressor is opened and closed reciprocatingly, then the movable plate moves back and forth in the movable groove, and the rubber plate vibrates reciprocatingly, which plays a role in clearing the dust materials gathered in the discharge channel.

[0032] In addition, the inner side of the movable groove is provided with a plurality of guide bars 23 parallel to the depth direction thereof, the movable plate is provided with guide grooves cooperating with the guide bars, and one end of the guide bar forms a blocking block 24 for blocking the movable plate.

[0033] Combination Figure 5 As shown, as a preferred structure, a discharge port is provided on the tank body, and side strips 30 are fixed on both sides of the discharge port, and a slide groove is provided on the side strips along the length direction thereof, and sliding strips 24 are provided on both sides of the discharge channel to be inserted into the slide groove, and a fastening screw 15 is inserted on the side strips, and the fastening screw is screwed to the sliding strips, and a block 16 is fixed on the side strips, and the block is a hollow structure, and a movable plate 17 is arranged inside the block, and the fastening screw passes through the block, and the fastening screw also passes through the movable plate. The sliding strip on the discharge channel can be inserted into the slide groove on the side strips on both sides of the discharge port, so that the discharge channel can be conveniently disassembled and assembled from the discharge port, and it is convenient to replace. The fastening screws screwed with the movable strips are inserted on the side strips, so that the tank body and the discharge channel are firmly connected. The fastening screw passes through the movable plate in the block, and the movable plate is clamped in the block, so that the fastening screw can maintain a movable connection with the block, avoiding the trouble of finding the fastening screw every time the discharge channel is fixed.

[0034] Combination Figure 6 As shown, a number of airbags 31 are fixed on the inner surface of the bottom plate of the tank body, one end of the airbag is connected to the air supply pipe 32, the air supply pipe is also connected to the air compressor, and the other end of the airbag has an exhaust pipe 33 connected to the outside of the tank body. The air compressor inputs compressed gas into the airbag through the air supply pipe, causing the airbag to expand.
