Abstract
A dry-type cleaning machine includes a negative pressure unit, a first dust gathering unit having a first dust sucking passage communicated with the negative pressure unit, and a barrel body. The barrel body has a receiving space communicated with the first dust sucking passage, a feeding inlet for a material to be sieved, a discharging portion, a rotary assembly in the receiving space, and a sieve layer. The material to be sieved includes crushed aggregates and dirt. The sieve layer is between the rotary assembly and the first dust sucking passage. The rotary assembly is for stirring the material to be sieved. The feeding inlet, the first dust sucking passage and the receiving space form a negative pressure passage. The sieve layer allows the dirt to pass through and enter the first dust sucking passage. The crushed aggregates are discharged out of the receiving space.
