Description

Technical Field

[0001] This utility model relates to the technical field of mortar spraying auxiliary devices, and in particular to a mortar spraying device with a cleaning structure. Background Technology

[0002] In modern construction, mortar spraying equipment is widely used in plastering interior and exterior walls, spraying insulation layers, and repairing concrete surfaces. Existing mortar spraying equipment typically includes main components such as a mortar tank, a mortar pump, a spray gun, and pipes.
