The invention discloses a coal mine stoping working face rotary telescopic TADA atomization spraying dust fall device, and relates to the technical field of coal mine underground dust prevention, the coal mine stoping working face rotary telescopic TADA atomization spraying dust fall device comprises two atomization sprayers and a coal mining machine, the coal mining machine comprises a coal mining machine body, and rocker arms are symmetrically arranged on the two sides of the coal mining machine body; the bottoms of the two atomization ejectors are rotationally connected with a support, a base is arranged below the support, a through hole is formed in the middle of the base, a rotating mechanism is arranged in the through hole and fixedly connected with the support, and a pitching mechanism is arranged between the support and the atomization ejectors. According to the coal mine stoping working face rotary telescopic TADA atomization spraying dust fall device adopting the structure, the jet orifice sprays high-speed jet spray through the rotary impeller mechanism, and the multiple nozzles arranged on the inner circle and the outer circle spray high-speed water flow, so that dust fall is effectively carried out; and the direction of the atomizing ejector is adjusted through the rotating mechanism and the pitching mechanism, all-directional dust falling is carried out, and the dust falling effect is greatly improved.

The accurate dustproof automatic cutting forming equipment comprises a circular saw blade cutting machine capable of moving up and down and moving left and right and an electric remote control car and further comprises a backflow pool, a bearing table is arranged on the backflow pool, the electric remote control car is arranged on the bearing table, a wallboard placing device is arranged at the top of the electric remote control car, and the wallboard placing device is arranged on the bearing table. Spraying heads are arranged on the two sides of a cutting saw blade of the circular saw blade cutting machine, the electric remote control car transports a wallboard to the position below the circular saw blade cutting machine, the circular saw blade cutting machine moves left and right to be positioned and moves downwards to conduct cutting, the spraying heads spray water mist to cool the saw blade, and floating dust is reduced. The large ALC wallboard cutting device is reasonable in structure, convenient to arrange and implement and good in using effect, large ALC wallboards can be automatically and accurately cut, the product quality is improved, dust can be effectively reduced in the process, dust pollution is greatly reduced, and slurry formed by water spraying and dust falling can be recycled.

This invention discloses a dust-proof and environmentally friendly construction waste recycling device in the field of construction waste recycling technology. It includes a magnetic mechanism and a crushing mechanism inside the outer shell. The crushing mechanism includes a cylindrical lifting block with multiple open cylindrical lifting block grooves at its bottom. The magnetic mechanism includes a cross-shaped magnetic suction frame. Both the lifting block grooves and the cross-shaped magnetic suction frame have independently controlled electromagnets built into them. This invention uses the magnetic suction mechanism and the crushing mechanism to lift and drop the cylindrical lifting block onto the concrete, effectively crushing it. Then, by raising the cross-shaped magnetic suction frame from the cylindrical lifting block and rotating it, the top layer of concrete is dispersed, and metal waste in the concrete is adsorbed layer by layer. This process is repeated until all the metal waste in the concrete is adsorbed, solving the problem of separating concrete and metal waste through crushing.
