Double-head self-cleaning conveying and metering double helix

The utility model relates to the technical field of spiral conveyors, in particular to a double-head self-cleaning conveying and metering double helix. Comprising a first screw rod and a second screw rod, the first screw rod and the second screw rod rotate in a meshed mode in the same direction, and rectangular grooves are formed in the discharging ends, close to the conveyor, of the first screw rod and the second screw rod. And the extruded materials can be crushed and scattered, so that the materials are uniformly discharged spirally. 本实用新型涉及螺旋输送机技术领域，具体为双头自清理输送计量双螺旋。包括第一螺旋杆和第二螺旋杆，第一螺旋杆和第二螺旋杆同向啮合转动，第一螺旋杆和第二螺旋杆靠近输送机的出料端开设有矩形槽。能够对挤压的物料破碎、打散，使螺旋均匀下料。
