Description

Technical Field

[0001] The utility model relates to the field of mining equipment, in particular to a mine-underground tunnel vibrating ore-retaining device. Background Art

[0002] The vibrating ore-discharging machine is a vibration-type inertial vibration ore-discharging equipment with a vibration motor as the excitation source. It is an ideal equipment for discharging, feeding or loading ore and other materials. Compared with other forms of ore-discharging machines, the vibrating ore-discharging machine has the following advantages: energy saving, high ore-discharging efficiency, uniform ore-discharging and easy control. The miner controls the vibrating ore-discharging machine to put the ore in the chute into the mine car, and then transports the ore to the ore-dressing ore bin through narrow-track transportation. In the actual ore-discharging process, in order to prevent the ore from falling and injuring the lower walking or maintenance personnel, it is necessary to install a ore-blocking device at the discharge port of the vibrating ore-discharging machine. However, the existing ore-blocking devices are mostly wooden or iron plates. Affected by the underground working environment and site, each ore-discharging requires the operator to climb up and pick it up manually, which is time-consuming and labor-intensive, difficult to operate, and has a large safety hazard. In addition, the ore-blocking effect is not ideal during the operation, and some ore will still fall onto the track, forming an obstacle in the ore transportation process, delaying the mining and transportation progress of the mine.

When it is necessary to discharge the ore, the U-shaped pin is removed, and the counterweight hammer 3 is removed from the hook of the tunnel 9 to make it fall freely. The counterweight hammer 3 drives the wire rope 4 to open the baffle 2 through the guiding effect of the fixed pulley 5. At the same time, the hanging rod 6 moves in a circle around the crossbeam 7. Under the action of the counterweight hammer 3, the baffle 2 is fully opened, so that the ore can flow out from the discharge port of the vibrating ore-discharging machine 8, and the ore-discharging work is completed. When the ore is discharged and the ore needs to be blocked, the counterweight hammer 3 is lifted up and hung on the hook on the inner wall of the tunnel 9. The baffle 2 falls and closes by its own weight, and the staff inserts the U-shaped pin into the pin hole 1 to lock the baffle 2 and the vibrating ore-discharging machine 8.
