Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, specifically a bucket elevator with a buffer lock. Background Technology

[0002] A bucket elevator is a continuous conveying equipment that vertically lifts materials. It mainly transports bulk materials upward in a vertical or near-vertical direction through a series of buckets fixedly connected to a conveyor belt.

[0003] The existing bucket elevators have the following main technical defects: When transporting bulk materials, if there is a power outage or equipment failure, some materials in the buckets may not be completely unloaded because the discharge port of the bucket elevator is on the upper side. Due to the different weights of the buckets suspended on both sides of the conveyor belt, the buckets carrying materials will tend to descend under the action of gravity, which will cause the conveyor belt to rotate in the opposite direction. The existing bucket elevators use anti-reverse ratchet and drive wheel to lock the drive wheel, but the buckets on the side carrying materials will continuously impact the locked drive wheel under the action of gravity. The direct impact can easily damage the drive wheel, which will affect the efficiency of subsequent material transportation and cause inconvenience to daily use. Utility Model Content
