The arc-shaped limit slot has limit bolts installed at both ends of the limit slot. The limit bolts can lock the limit column at the end position of the arc-shaped limit slot. The top of the V-shaped frame and the position where the bottom roller axle is installed are both equipped with quick-release buckle covers. The top of the V-shaped frame is provided with a T-shaped blind hole. The quick-release buckle cover is equipped with a T-shaped block that matches the T-shaped blind hole. A fan-shaped plate is also installed on the arc-shaped limit plate. When the limit bolts lock the limit column at the end position of the arc-shaped limit slot, one of the bottom rollers rotates to the highest position and the fan-shaped plate can limit the separation of the quick-release buckle cover and the V-shaped frame. The other bottom roller rotates to the lowest position and the quick-release buckle cover separates from the fan-shaped plate. A reinforcement plate is connected between the two V-shaped frames, and each reinforcement plate is equipped with a push-pull handle, which is located in the middle of the reinforcement plate. The outer circumference of the limiting column is wrapped with a rubber pad, and the ends of the arc-shaped limiting groove are installed with a buffer mechanism, which includes a buffer plate. A buffer spring is installed between the buffer plate and the arc-shaped limiting plate, and the buffer spring and the buffer plate are both located in the arc-shaped limiting groove.

[0004] This patent has a complex structure. When replacing the horizontal roller, workers need to enter the conveyor frame, which makes replacement difficult. In addition, the inclined roller cannot be replaced while the belt conveyor is working, and the machine needs to be shut down for processing, affecting production. Utility model content:
