Bin discharge mechanism of circular bin

Abstract

The invention relates to a bin discharge mechanism of a circular bin. The bin discharge mechanism comprises a main speed reducer, a coupling, a discharge auger and a tail mechanism; the main speed reducer is positioned in center of the bin; an output shaft of the main speed reducer is connected with an auger shaft of the discharge auger through the coupling; an outer end of the auger shaft is connected with the tail mechanism; the part, beside two ends, of the auger shaft is formed by embedding and welding multiple hollow long shafts in sequence; the number of embedded layers near the middle part of the auger shaft is bigger; spiral blades are axially wound at the outer periphery of the auger shaft, and are uniform in pitches on each section of step shaft; and the volumes in the pitches of the spiral blades are gradually increased from tail ends to center ends. Blades for shearing materials are respectively mounted on the outer edges of all the spiral blades. The output shaft of the main speed reducer is supported on wall boards on two sides of the main speed reducer through double rows of radial spherical roller bearings; and a two-way thrust ball bearing is mounted at one end, far from the discharge auger, of the output shaft of the main speed reducer. The bin discharge mechanism can bear higher radial force and two-way axial force, and is low in failure rate.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a bin discharge mechanism for a circular feed bin, and belongs to the technical field of bin discharge machines. Background technique [0002] Grain, soybean meal and other materials are usually placed in silos for long-term storage, and the bottom of the silo is equipped with a discharge machine for outputting materials. The discharge port of the silo is located at the bottom center of the silo. The main shaft system of the discharge machine includes the main reducer, coupling, auger shaft and tail end bearing. The main reducer is located on the axis of the silo, and the output of the main reducer is The shaft is connected with the driving end of the auger shaft through a coupling, and the outer end of the auger shaft is supported on a circular guide rail through a tail end bearing. When discharging, the main reducer drives the auger shaft to rotate through the coupling, and the auger shaft ...

AI Technical Summary

Problems solved by technology

[0004] Since the coupling of the silo machine in the prior art cannot withstand the reverse axial force generated by the reversal, the silo roof can only be lifted, and it takes half a month to a month to remove the silo. The material is cleaned up, and then the auger shaft can be restarted, which is time-consuming and laborious
