The invention discloses a stope debris flow treatment method in a caving mining method and a device of the method. In a stope ore discharge opening position of the caving mining method, before the stope ore discharge, an impact device is used for beating a water filtering steel pipe into a caving ore pile with the debris flow harm; water filter holes are uniformly distributed in the insertion front end of the water filtering steel pipe; the tail end of the water filtering steel pipe is connected with the suck-in end of a slurry pump through a rigid flange; the slurry pump is started; the blockage of the water filtering pipeline by debris flow slurry in the ore pile is eliminated through the negative pressure influence and the vibration effect exerted on the water filtering pipeline by the slurry pump; slurry and water in the ore pile is discharged as fast as possible; then, the impact device is continuously used for beating the water filtering steel pipe into a deeper position, with the debris flow damage, of the ore pile; slurry is discharged by the slurry pump; the operation is circulated in such a way until the slurry quantity in the stope ore pile is greatly reduced; the stope debris flow damage is eliminated. The method has the advantages that the operation is simple and convenient; the pipe blockage probability by mud and stones is low; the water discharge and mud discharge speed is high; the stope debris flow treatment effect is good; the water filtering steel pipe can be cyclically used, and the like.

The invention discloses a hub blade automatic riveting machine comprising a stand, a medium tube, a medium tube pressing upper die, a middle tube pressing lower die, a blade vibrating disk, a middle tube vibrating disk and a blade ejector. The blade vibrating disk is connected with the stand through a blade slideway; the medium tube vibrating disk is connected with the medium tube pressing lower die through a medium slideway; the blade ejector fixes the blades on a blade positioning die on the stand; the medium tube pressing upper die and the medium tube pressing lower die are controlled through an air pressure cylinder; two blade positioning dies are externally provided with an oil cylinder respectively; and both sides of the blade ejector are provided with small roller cones. When the hub blade automatic riveting machine is used, the blades and the medium tube are respectively arranged in the blade vibrating disk and the medium tube vibrating disk; the blades enter into both sides ofthe blade ejector through the blade slideway; the medium tube enters into the medium tube pressing lower die through the medium tube slideway; the blades are positioned through the blade ejector, andthen the medium tube is positioned; and the oil cylinder moves towards the middle for riveting. The invention patent adopts the automatic operation, thereby reducing the work, lowering the cost, reducing the labor, and improving the quality and the stability of products.
