The invention discloses a perforating device for onion seedling transplanting, which comprises a frame, a moving wheel, a gasoline engine mounted on the frame, a support shaft, a driving part and a perforating assembly, the moving wheel is mounted on the frame through the support shaft, the gasoline engine is matched with the support shaft to drive the moving wheel to rotate, and the moving wheel moves; the driving parts are symmetrically arranged on the two sides of the frame and connected with the supporting shaft, the punching assembly comprises two rotating rods arranged in parallel, a fixing shaft, a supporting rod, a support, a lifting plate and a punching cone arranged at one end of the lifting plate, and the driving parts are connected with the fixing shaft on one rotating rod. The device is convenient to move due to the arrangement of the moving wheels, the purpose of punching soil after soil turning can be achieved due to the arrangement of the punching assembly, it can be guaranteed that the distances between punched holes are the same, and the punching efficiency and the punching quality are greatly improved.

The application relates to the technical field of building insulation boards, and provides a fabricated building insulation floor slab, which comprises two parallel formworks, the opposite sides of the two formworks are provided with insulation boards, a plurality of symmetrical connecting frames are arranged on the formworks, U-shaped steel bars are arranged between the two symmetrical connecting frames, vertical steel bars and horizontal steel bars are bound between the U-shaped steel bars, and a pouring layer poured through concrete is arranged between the two insulation boards. The fabricated building insulation floor slab has the beneficial effects that the two symmetrical formworks and the insulation boards are fixed through the U-shaped steel bars, and the pouring through the concrete improves the overall stability, the insulation effect is realized through the insulation boards, the two adjacent formworks are quickly assembled, the energy-saving and efficiency-reducing function is realized, the working efficiency is improved, and the building insulation energy-saving effect is improved.

The utility model relates to the technical field of pipeline desilting, and solves the problem that most desilting machines can only desilt drainage pipelines with single sizes, so that the application range of a sewage pipeline desilting device is narrow. The self-diameter-adaptive railway tunnel drainage pipeline dredging device comprises a dredging mechanism which forms an acting surface on drainage pipeline sludge, and a supporting mechanism which circumferentially surrounds the dredging mechanism to support the dredging mechanism and comprises two fixed connecting rings, the two fixed connecting rings are connected through a fixed rod, and the fixed rod is connected with the dredging mechanism. A plurality of fixed side plates used for forming a central supporting surface are arranged in the two fixed connecting rings, a camera used for observing the working condition in the pipeline is arranged on one of the fixed side plates, and the guide mechanism is arranged between the two fixed connecting rings, is used for self-adapting to the change of the pipe wall and is provided with a guide rail connected with the fixed connecting rings; and two moving rods penetrating through the guide rail are mounted on the guide rail in a bilateral symmetry manner.

The utility model provides a simple and portable device for protecting glass by a tempered cleaning frame basket strip, which comprises a placing frame, the placing frame is provided with an insertion hole and two sliding holes, the placing frame is connected with a placing assembly, the placing assembly comprises a fixed base, a U-shaped caliper, a spring and a telescopic rod, and the telescopic rod is slidably connected with the sliding holes; the top of the U-shaped caliper is provided with a fillet, and the U-shaped caliper is connected with the fixed base through a bolt. The spring is compressed by pressing the telescopic rod, so that the limiting convex body is separated from the clamping groove, the fixed base is moved, the distance between the U-shaped calipers is adjusted, glass of different sizes can be placed, the U-shaped calipers are smoother through fillets at the tops of the U-shaped calipers, badness cannot be caused when the glass is placed, the badness risk is greatly reduced, and the production efficiency is improved. The safety problem in the transportation process can be eliminated; and the base and the U-shaped caliper are connected and fixed through bolts, so that the U-shaped caliper can be conveniently detached for maintenance.
