In order to make the running chain rotate flexibly at the hinge, reduce wear, and extend its service life, this machine has designed a lubrication device for the chain hinge. The device is a container that can hold approximately 45Kg of lubricating oil, with an oil pipe installed underneath the container. The oil flow rate is adjusted through a plug. The oil pipe has four drip nozzles, each of which supplies oil at a rate of 18-19 drops per minute, lubricating the chain hinges below. The refueling device can be installed on the crossbeam of a bracket that is convenient for refueling and adjusting the amount of oil dripping according to the on-site situation.

Accident alarm and parking device

This conveyor is equipped with two types of accident alarm and parking devices, namely rope switches installed along both sides of the conveyor and proximity switches located at the tail of the conveyor. The former is convenient for on-site workers to handle emergency parking; The latter is used for conveyor operating components to automatically stop and alarm when faults occur due to jamming or other reasons.

The working principle of the proximity switch is as follows: the proximity switch is installed on the end cover of the tail wheel bearing of the conveyor. When the tail wheel shaft equipped with an induction plate rotates, the proximity switch is triggered to generate a pulse series, which is transmitted to the computer system. When the pulse series from the proximity switch is lower than the set value range of the normal rotation speed of the tail wheel shaft (its speed is determined by the equipment), the computer system controls the equipment to automatically stop, The setting of the computer control system should avoid the opening time of the motor and transmission device, that is, during the equipment opening time, the proximity switch should not function.
