Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a self-cleaning device for a material feed chute used in road marking construction. Background Art

[0002] Road marking construction refers to the process of drawing various traffic markings on roads. These markings are used to guide and regulate traffic behavior, improve road capacity and driving safety. Marking materials primarily include paint, templates, and brushes. Marking paint should be a specialized paint with good wear and weather resistance. Templates should be made of durable, non-deformable materials, such as color plate. The placement of markings, such as lane markings, crosswalks, and stop lines, should be determined based on actual conditions. The width and spacing of markings should be determined according to standards and actual conditions. Road marking construction requires strict adherence to relevant standards and specifications to ensure clarity, wear resistance, and durability, thereby improving road traffic safety and efficiency.

[0003] Usually, the device used in road marking construction is equipped with a feed chute, but usually there is no self-cleaning structure in the feed chute. During the road marking construction process, paint may remain in the feed chute and gradually accumulate, resulting in poor feed or blockage. If the residue in the feed chute is not cleaned in time, it may cause the surface of the marking to be uneven, affecting the appearance and use effect of the marking. At the same time, the accumulation of residue in the feed chute may cause unstable paint flow, which in turn affects the thickness uniformity of the marking, the reflective effect and service life of the marking, and brings certain adverse effects to people's use process. For this reason, we propose a self-cleaning device for a feed chute for road marking construction. Summary of the Invention

The cleaning control frame can be moved between them to enhance the guiding stability. The limit block at one end of the guide rod plays a limiting role to prevent slipping.
