Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveying equipment, in particular to an energy-saving feeding device for a bucket elevator. Background Art
[0002] In the field of solid bulk material transportation, bucket elevators are widely used. When the bucket elevator is working, the material enters the hopper of the elevator from the lower feed port of the elevator. The material is lifted to the required height through the hopper and discharged from the discharge port of the elevator. Generally, the material enters the elevator from the feed port, most of the material enters the hopper, and some of the material cannot enter the hopper and falls into the lower part of the elevator. The material is dug by the hopper, which not only increases the operating resistance of the elevator, but also increases the wear of the hopper and increases the maintenance cost of the equipment. The current bucket elevators are directly loaded through the feed port and the hopper. For example, the disclosed patent 2018112373186 discloses a bucket elevator. A certain gap is left between the feed port and the traction member of the elevator to prevent the hopper and the feed port from scratching during normal operation of the elevator, resulting in damage to the hopper and the traction member. When the gap is too small, scraping occurs between the hopper and the feed port. When the gap is too large, the material cannot completely enter the hopper, and some of the material falls directly to the bottom of the elevator. The material at the bottom can only be taken away by digging through the hopper, which increases the running resistance of the elevator. The elevator has to use part of its energy to overcome this part of the running resistance, and this part of the energy is useless. Utility Model Content
[0003] The purpose of the utility model is to provide an energy-saving feeding device for a bucket elevator. A movable feeding device is added between the feed port and the hopper. This device is seamlessly connected to the hopper. The purpose is to allow all materials to enter the hopper and prevent them from falling to the bottom of the elevator, thereby eliminating the operating resistance of the elevator and saving energy.
[0004] The utility model provides an energy-saving feeding device for a bucket elevator, comprising a machine body, a transmission chain, a hopper, a power motor and a steering support wheel, wherein the transmission chain is arranged in the machine body, the hopper is suspended on the transmission chain, the power motor is arranged between the transmission chains, and the transmission chain is steered by the steering support wheel, a feeding port is provided on one side of the machine body, the feeding port is inclined and arranged facing the approaching hopper, a feeding device is provided at the lower end of the feeding port, the feeding device comprises a mounting shaft, a feeding trough and a baffle, the mounting shaft is arranged at the upper end of the feeding trough, the baffles are arranged on both sides of the feeding trough, and the mounting shaft is mounted at the lower end of the feeding port of the machine body through a shaft seat.
[0005] A further improvement is that one end of the feed trough rotates around the mounting shaft, and the other end of the feed trough is located directly above the hopper. When the hopper is running, the feeding device moves upward with the hopper to avoid the hopper. After the hopper passes, it automatically falls back to the next hopper outlet.
[0006] A further improvement is that an anti-collision barrier strip is provided at the lower end of the feed chute, and the feed chute is protected by the anti-collision barrier strip made of soft material.
