Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and in particular to a sweeper and engineering machinery. Background Technology
[0002] In the unloading operations of large bulk cargo ships at ports, such as those transporting grain, coal, and salt, the inner walls of bulk carrier holds are generally reinforced with ribs in a "III" shape. The distance between two ribs is small. The width of the buckets of excavators and loaders is larger than the gap between the ribs, making it impossible to reach into the gaps between the ribs to clean up the material accumulated in the corner areas.
[0003] Existing technologies include: 1. Manual cleaning: using climbing equipment and simple hand tools such as bamboo poles and shovels to remove the attached materials from the ship's bulkhead. 2. Cleaning with high-pressure water guns: the high-pressure water guns are installed on the unloading machine's material handling head and are remotely controlled by personnel to clean the bulkhead. 3. Cleaning with a single roller brush, scraper, or narrow bucket.
[0004] The shortcomings of existing technology are: 1. Manual cleaning is inefficient, time-consuming, and labor-intensive; 2. Workers need to use climbing equipment or climb ladders to reach high places for work, and there is a risk of slipping and falling from heights. 3. High-pressure water gun cleaning will leave a large amount of water in the cabin, which is not conducive to cleaning the bottom of the cabin and will affect subsequent use; 4. A single roller brush can only clean relatively loose materials, and cannot clean compacted materials, and generates a lot of dust during the process.
[0005] 5. The movement can only be achieved by connecting to the working boom to extend, move up and down and rotate. The sweeping mechanism does not have an independent controllable direction of movement.
[0006] 6. The sweeper mechanism is rotated by connecting to the working arm. Due to its height, the sweeping mechanism has poor micro-motion in left and right rotation, making it difficult to control. Utility Model Content
