The utility model discloses provide a self-weight formula photoelectric switch stop device, including base, sliding assembly, connecting assembly and photoelectric switch subassembly, and the stationary part of base is opposite fixed with target equipment, and sliding assembly includes fixed installation on the slide bar base of base, and two slide bars of parallel connection on the slide bar base and two sliding blocks of respectively slidablely cover in two slide bars, and connecting assembly includes the counterweight of connecting between two sliding blocks, the pulley of rotatable connection in counterweight and connecting rope, and the one end of connecting rope is opposite fixed with slide bar and is used for and the movable part of target equipment is connected in the other end, and photoelectric switch subassembly is installed in base, and photoelectric switch subassembly is used for detecting the height position of counterweight. The application scheme of the utility model, avoided the displacement of the movable part of target equipment when target equipment was impacted, improved the stability of the height position measurement of the movable part of target equipment.

The application discloses a screening construction method for soil for slope ecological restoration, and is suitable for separation of gravel particles and mud components in moist engineering soil required by spray seeding construction. The method realizes soil and stone separation by means of water mixing, mechanical stirring, standing and settling, upper mud transfer and screen filtering of a mud separation tank, does not need special wet screening equipment, is simple in construction and strong in adaptability, can effectively reduce the risk of blockage of a spray seeding machine pipeline and a nozzle, and improves the continuity and stability of spray seeding construction.

The invention belongs to the technical field of insect trapping, and particularly relates to a field portable insect trapping device which comprises a bottom plate, a plurality of moving wheels are fixedly mounted on the bottom wall of the bottom plate, each moving wheel is a universal wheel, and a two-way screw is rotatably mounted on the upper end face of the bottom plate through a fixing frame. And a servo motor connected with the two-way screw rod is fixedly installed on the outer wall of the fixed frame, two moving sleeves are installed on the outer wall of the two-way screw rod through limiting mechanisms in a threaded mode, first connecting frames are fixedly installed on the upper end faces of the two moving sleeves, and second connecting frames are connected to the interiors of the two first connecting frames through connecting mechanisms. The device has the advantages that the trapping efficiency is high, the range is wide, three mainstream trapping technologies of lamplight, pheromones and sticky plates are physically integrated for the first time, a specific light source and a color plate can be utilized for broad-spectrum trapping, accurate monitoring and trapping of target pests can be achieved through pheromones, and the scientific research or monitoring value of single-time arrangement is remarkably improved.
