when the hot slag material with corresponding weight falls into the hot press 35, the first gravity sensing switch 27 enables the second hydraulic telescopic rod 31 to perform telescopic movement, the second hydraulic telescopic rod 31 drives the briquetting die 30 to descend and press the hot slag material body on the hot slag material body, the second hydraulic telescopic rod 31 drives the briquetting die 30 to ascend, the lifting block 32 ascends along with the lifting block, the lifting block is extruded to pass through the bottom of the movable rotating block 33 in the ascending process and acts on the pressure sensing switch 34, the pressure sensing switch 34 enables the third hydraulic telescopic rod 25 to stretch, the third hydraulic telescopic rod 25 drives the jacking block 26 to transversely move, the formed lump materials are pushed to slide to the discharge hole 28 and are discharged from the discharge hole 28, and when the lump materials are discharged, the laser sensing switch 29 senses, the third hydraulic telescopic rod 25 is contracted and drives the jacking block 26 to reset, so that automatic briquetting discharging operation is realized, meanwhile, the laser sensing switch 29 also enables the fourth hydraulic telescopic rod 22 to shrink to realize resetting of the material plate 23, the resetting along with the lifting block 20 is also realized, the gravity guide plate 15 is conveniently lowered, and the annular steel material is in linkage with the annular steel body to be continuously discharged.
The foregoing describes one embodiment of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
