The reel winds up the rope, and the counterweight block rises along the inner wall of the limiting cylinder. The gravity of the counterweight block provides a reaction force for the movement of the luggage, reduces the moving speed of the luggage, buffers the luggage, allows the luggage to fall smoothly on the conveyor belt, prevents the luggage from colliding with the casing, reduces the friction between the luggage and the conveyor belt, and protects the luggage. Step 2: When the luggage is separated from the baffle, the weight of the counterweight pulls the rope, the reel rotates, and the baffle returns to the initial position under the transmission of the first bevel gear and the second bevel gear, so as to prepare for the luggage buffering; Step 3: When the surface of the conveyor belt needs to be cleaned, the mounting seat is pushed downward by the cylinder until the roller brush contacts the conveyor belt, and the first spur gear is driven by the motor to rotate. The roller brush rotates under the transmission of the first spur gear and the second spur gear, and the roller brush scrubs the stubborn impurities on the surface of the conveyor belt; Step 4: When the fan is started, negative pressure is formed in the dust removal cylinder. When the connecting pipe is connected, negative pressure is formed in the inner cavity of the roller brush. The air holes suck away the gas on the surface of the conveyor belt, taking away the impurities on the surface of the conveyor belt. After entering the wind hood, the filter cylinder filters the dust and other impurities, and discharges them after purification, so as to clean the conveyor belt and ensure the hygiene of the conveyor belt.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention blocks the luggage from moving on the roller by the baffle, the second rotating shaft rotates, the first bevel gear and the second bevel gear drive to rotate the reel and the turntable, the reel winds up the rope, the counterweight rises, and the gravity of the counterweight blocks the rotation of the baffle, so that the baffle slows down the movement speed of the luggage, so that the luggage can fall smoothly on the conveyor belt. Therefore, the luggage reaching the conveyor belt can be buffered to prevent the luggage from being impacted, and the protection is strong to avoid damage to the luggage.

[0014] 2. The present invention uses a cylinder to push the mounting seat to swing downward, allowing the roller brush to contact the conveyor belt. Driven by the motor, the first spur gear and the second spur gear drive the roller brush to rotate, and the roller brush scrubs the stubborn debris on the surface of the conveyor belt. At the same time, the fan creates a negative pressure in the dust removal cylinder, and the air holes suck in impurities on the conveyor belt. The gas is discharged after being filtered by the filter cylinder, which has the function of cleaning the conveyor belt, preventing dust and other debris from scratching the surface of the luggage, and making the luggage retrieval more hygienic.
