Claims

[Claims for Utility Model Registration] (1) Two main screws 1 with the main screw blades 1b wrapped and fixed around the rotating shaft 1a are arranged parallel to each other with the main screw blades wedged in, and have cross sections of the same size. A timing gear 6 is fixed to the upper part of each rotating shaft 1a to rotate both rotating shafts synchronously, and a timing gear 6 is fixed to the upper part of each rotating shaft 1a to rotate both rotating shafts synchronously. A biaxial vertical screw lifter in which a charging hopper 4 is connected to an opening 2b on the side surface and a discharge chute 5 is connected to an opening 2c on the upper side surface. (2) In the biaxial vertical screw lifter according to claim 1 of the utility model registration, the main screw blade 1b and the counter-threaded secondary screw blade 12 are attached above the main screw blade 1b of each rotating shaft 1a, and the two main screw blades are 1,
A biaxial vertical screw lifter in which one sub-screw blade 12, 12 is embedded into each other. (3) In the biaxial vertical screw lifter according to claim 1 of the utility model registration, the rotation axis 1 of the two sub-screw blades 12, 12 provided on the two main screws 1, 1.
A two-axis vertical screw lifter that allows you to freely change the mounting angle to a and 1a. (4) In the biaxial vertical screw lifter according to claim 1 of the utility model registration, the support shaft 9 vertically protrudes into the casing from the bottom plate 3 that closes the lower end of the casing 2.
