Description

Technical Field

[0001] This utility model relates to the field of bulk material loading devices, and in particular to an automatic leveling loading chute device. Background Technology

[0002] When loading bulk materials into train cars or containers, loading chutes are usually used to level the materials, especially during the loading of coal, where the coal material on the top of the car needs to be leveled using loading chutes.

[0003] The disadvantages of traditional loading chutes are as follows: (1) There is no chute width adjustment device. The scraper is used to adapt to the width of the car body, which leads to coal leakage and coal spillage, polluting the air and resulting in poor coal leveling effect. (2) The hydraulic cylinder does not have a built-in displacement sensor and cannot be automatically adjusted. Coal leveling and loading are controlled manually, which is labor-intensive and has a low degree of automation. Utility Model Content
