This utility model discloses an anti-clogging suction pipe structure for powder material suction and filling. It includes a feed pipe and an air inlet pipe, with the air outlet of the air inlet pipe connected and fixed to the wall of the feed pipe in a section with densely packed feed holes. This allows the powder material and the suction gas to form a certain solid-gas ratio within the section with densely packed feed holes before being conveyed in the feed pipe. This reduces the conveying resistance of the powder material and improves the pneumatic suction efficiency. Under undemanding operating conditions, it maintains a stable conveying state of the powder material without accumulation or blockage, improving the conveying efficiency, reducing energy consumption of pneumatic suction, and enhancing the reliability and stability of pneumatic suction. Furthermore, by installing an air inlet regulating valve in the air inlet pipe, the solid-gas ratio formed by the powder material and the suction gas can be adjusted to an optimal ratio suitable for the powder material and operating conditions.
