Description

Technical Field

[0001] The utility model relates to a self-propelled spiral car unloading machine, belonging to the field of railway transportation. Background Art

[0002] A screw unloader is a mechanical device used to transport and unload materials, in which the screw mechanism plays a key role. It is usually used to unload bulk materials from storage containers or transportation equipment. Bulk materials such as granular or powdered coal are pushed forward along the screw axis through the rotation of the screw. However, most of the existing screw unloaders are fixed, that is, a traction mechanism and a track are required to transport the carriage containing materials to the bottom of the screw unloader. After the unloading is completed, the carriage is moved away so that the next carriage can fill the position. In this way, since the position of the screw unloader is fixed, it has certain limitations in dealing with different site layouts and conditions, which may make it less suitable in some working environments, unable to be flexibly moved and adjusted, and unable to meet the high-speed unloading requirements of large-scale simultaneous unloading. At the same time, since fixed screw unloaders are usually not easy to disassemble or clean, their maintenance and cleaning may be more difficult, which may lead to reduced equipment operating efficiency or accumulation of accumulated materials after long-term use.

[0003] Therefore, it is urgent to propose a new type to solve the above-mentioned technical problems. Utility Model Content

The self-propelled spiral unloading machine of the present embodiment comprises a travelling mechanism 1, a slewing mechanism 2, a driver's cab 3, a hoisting mechanism 4, a steering mechanism 5, a spiral mounting seat 6, a driving mechanism 7, a spiral unloading roller 8 and a side disc brush 9. The slewing mechanism 2 is mounted on the top of the travelling mechanism 1. The driver's cab 3 and the hoisting mechanism 4 are mounted on the slewing mechanism 2. The top of the spiral mounting seat 6 is mounted on the end of the hoisting mechanism 4 through the steering mechanism 5.
