Description

Technical Field

[0001] This utility model relates to the technical field of material conveying, and in particular to a dust isolation auger split base. Background Technology

[0002] Screw conveyors can be arranged horizontally, inclined or vertically. Driven by a motor, the screw blades transport materials in the trough from the feed point to the discharge point. They are widely used conveying equipment in industries such as mining, feed, grain and oil, and construction.

[0003] In existing augers, the bearing and dust seal at the bottom are usually an integrated structure. When the auger conveys materials, the material exerts significant pressure on the bottom of the auger. Small particles can easily enter the dust seal due to this pressure, causing wear on both the bearing and the dust seal. A utility model patent with application number 2016100914295, entitled "Auger-Type Melamine Plastic Powder Conveyor," aims to solve this problem. This patent addresses this issue by setting a powder accumulation space 10 without auger blades at the end of the conveying channel 2 below the inlet 4. This powder accumulation space 10 reduces the squeezing and wear caused by the rotation of the auger blades. However, this method leaves material residue in the powder accumulation space at the bottom of the conveyor. This residue is prone to deterioration and mold growth, requiring frequent disassembly and cleaning, and needs improvement. Utility Model Content

[0015] Preferably, the auger chassis is fitted onto the bottom of the auger cylinder, and a set screw is provided on the outer side of the auger cylinder to coaxially and fix the auger chassis and the auger cylinder together.

[0016] The beneficial effects of this utility model are:

[0017] (1) The bearing and auger of this utility model adopt a split structure, and the dustproof sealing ring is set on the outside of the auger base, which avoids the material from entering the dustproof sealing ring and causing friction with the bearing. It is not necessary to set up a powder accumulation space in the auger, which effectively improves the service life of the bearing and auger.

[0018] (2) This utility model adopts a concave-convex fit structure between the dustproof turntable and the auger base, which can block the flow of materials. A two-stage sealing structure is formed by setting a sealing washer at the auger main shaft with screws, which has the advantages of good dustproof effect and long service life.
