Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, and in particular to a discharge gate structure for a scraper conveyor. Background Technology

[0002] Scraper conveyors are commonly used material conveying equipment in mining, chemical, and building materials industries. They use a scraper chain to drive scrapers to move within a trough, achieving continuous material conveying. The discharge gate, as an important component of the scraper conveyor, is used to control the opening and closing of the discharge port and adjust the discharge rate.

[0003] Existing scraper conveyor discharge gate structures mostly adopt a simple sliding gate design, which has the following problems: First, there is a height difference between the traditional discharge gate and the scraper conveyor base plate, creating a material accumulation space that is prone to mold growth and contamination of subsequent materials over time; second, the gate lacks a stable guiding structure during opening and closing, making it prone to deviation and jamming, affecting the stability of discharge control; third, the discharge pipe is fixedly installed below the scraper conveyor, making cleaning inconvenient. These problems all affect the overall operating efficiency and performance of the scraper conveyor, failing to meet actual production needs. Therefore, it is necessary to propose a new discharge gate structure for scraper conveyors. Utility Model Content
