(1) Lubricating oil should be added to transmission parts such as bearings, gears and chains regularly.
(2) After the box conveyor is stopped, the wear of the spiral blades should be checked, and repair welding should be performed if the wear is serious.
(3) The conveying volume should not be overloaded, otherwise the material cannot be discharged, causing the spiral shaft to bend and the box to swell.
(4) When the conveying medium is of high viscosity, it should be noted whether the expansion and contraction of the box is free and there is no jamming. If there is any, it should be solved immediately.
(5) When the conveyor is running and the noise is harsh, the cover should be opened for inspection to eliminate the fault.
