Description

Technical Field

[0001] The invention relates to the technical field of material cleaning, and in particular discloses a material cleaning vehicle. Background Art

[0002] In the busy port operation scene, the port conveyor belt, as a key equipment for material transportation, undertakes the task of efficiently unloading and transferring various bulk cargoes such as coal, ore, grain, etc. from cargo ships to designated storage areas. However, in this seemingly smooth logistics process, the port conveyor belt may drop materials below.

[0003] This situation may occur in many links. Sometimes, it is because the materials on the belt conveyor are piled too densely or irregularly, causing some materials to fall off due to squeezing or bumping during the conveying process; sometimes, it is because the belt conveyor runs too fast and the materials fail to adapt to the speed change in time, so they are thrown out at the turning or inclined section; even worse, it may be that the belt conveyor itself has some wear or failure, such as loose belts, damaged rollers, etc., which causes the materials to be unable to remain stable during the conveying process and eventually fall off.

[0004] If the above-mentioned falling materials are not cleaned up in time, they will not only pollute the environment, but also gradually accumulate and easily rub against the rollers, causing excessive wear between the belt and the rollers and drums, increasing operating costs and equipment risks. The existing cleaning operations require a lot of manual labor, and there are also safety hazards when personnel clean under the belt conveyor. There are also self-guided sweepers on the market that can clean according to the planned path, but the collection box of the existing sweepers needs to be manually disassembled and assembled, and then the collection box is lifted and dumped, which increases the amount of manual labor. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a material cleaning vehicle to solve the problem of heavy labor caused by manually lifting and dumping a collection box.
