Description

Technical Field

[0002] Bulk loader is a kind of packaging equipment. Commonly used bulk loader include clinker bulk loader, bottom bulk loader, side bulk loader, etc. When the transport tool enters the position, open the rod valve for the corresponding number of rods, press the down button of the control cabinet, and the power supply of the lifting motor will be automatically disconnected after the discharge head is in place. Press the loading button to enter the unloading state, and the auxiliary equipment will start working accordingly. The dust generated by unloading passes through the feed hopper and enters the dust collector for purification through the telescopic dust collection hose. When the material at the discharge head is full, the discharge head rises and alarms. The rising distance must be set before loading.

[0003] In the related art, a bulk loader with stable material discharge (Announcement No.: CN219807483U) was found through searching. When in use, a telescopic tube is set, and the telescopic tube includes a number of support rods corresponding to the support rings. When the external hose is extended or retracted, the telescopic tube retracts or retracts along with it. The telescopic tube has a certain rigidity, so that the external hose can only move up and down stably, thereby improving the stability of material discharge.
