Hopper detachment refers to the phenomenon of the hopper falling off the hopper belt during production.
When the hopper falls, it will produce abnormal noise. It is necessary to stop the machine for inspection in a timely manner, otherwise it will cause more hoppers to deform and fall off; At the position where the hopper is connected, the hopper belt is torn.
The main reasons for hopper detachment are:
(1) Excessive feeding can cause material accumulation in the machine base, increase lifting resistance, and hinder the operation of the hopper, which is the direct cause of hopper detachment and deformation. At this time, the machine should be stopped immediately, the lower insertion plate of the machine base should be removed, the accumulated material in the machine base should be discharged, a new hopper should be replaced, and then the production can be started again. At this point, reduce the feeding amount and strive for uniformity.
(2) The position of the feed inlet is too low. Generally, during production of the elevator, the hopper automatically takes up the material coming in from the feed inlet. If the position of the feeding port is too low, it will cause the hopper to not be able to take up the material in time, and most of the material will enter the machine base, causing the hopper to scoop up the material. And if the material is in the form of blocks, it is easy to cause deformation and detachment of the hopper. At this point, the feeding port position should be adjusted above the centerline of the bottom wheel.
(3) The material of the hopper is not good and its strength is limited. The load-bearing components of the hopper elevator have high requirements for its material. When installing, it is recommended to choose materials with good strength as much as possible. Generally, the hopper is welded or stamped from ordinary steel plates or galvanized sheets, and its edges are folded or rolled with lead wires to enhance the strength of the hopper.
(4) Failure to clear the accumulated material in the machine base during startup often leads to sudden power outages or other reasons causing machine shutdowns during production. If the accumulated material in the machine base is not cleared during restart, it can easily cause the hopper to break and fall off due to excessive impact. Therefore, between shutdown and startup, it is necessary to remove the accumulated material debris in the machine base to avoid the hopper falling off. In addition, regularly check whether the connection between the hopper and the hopper belt is firm. If loose or detached screws, skewed or damaged hoppers are found, they should be repaired or replaced in a timely manner to prevent larger accidents from occurring.
