The invention provides a tobacco seedling stage film uncovering machine which comprises a rack, operating handles, a motor and transmission shafts, wherein the lower ends of the operating handles are fixed on the rack; walking wheels are arranged at the bottom of the rack; the motor is fixed on the rack; the transmission shafts are rotationally arranged on two sides of the rack respectively and in transmission connection with the output shaft of the motor; a film winding roller is fixed on each transmission shaft in a sleeving manner. By adopting the tobacco seedling stage film uncovering machine, the problems that a conventional film uncovering machine is likely to damage tobacco leaves, difficult in film unloading, unable to carry out continuous film uncovering, large in size, large in power, instable in operation process and has certain limitation, a mulching film of crops in mountainous areas is generally recycled manually, the labor intensity is high, the production efficiency of the crops in the mountainous areas can be greatly affected, and the like can be solved. The tobacco seedling stage film uncovering machine belongs to the field of mulching film recycling.

The invention provides a solar support. The solar support comprises a connection member, a support member and a press block. The connection member comprises a first connection plate, a second connection plate, a third connection plate and a fourth connection plate. The support member is of an integral structure and comprises a center support piece, left and right support pieces and a Y-type connection piece. The cross section of the press block is in the shape of an L and comprises a base plate and a side plate. A clamping plate is arranged on the outer side of the side plate. A clamping projection block is arranged on the outer side of the top of the side plate. The connection member is perpendicularly crossed with the support member. The connection member is fixed on the support member via the press block. In use, the clamping plate of the press plate is clamped in a fixed cavity body of the connection member and on the fixed plate; the clamping projection block on the top of the press block is clamped into a groove in the second connection plate; and a bolt and a nut are used for pressing the press block on the support member. Via the special structure design and connection assemblies, stability, supporting force and safety performance of the support are greatly improved.

The invention relates to an auxiliary device for building supervision. The auxiliary device comprises a mounting base, a tamping leg is fixedly connected to the bottom surface of the mounting base, ananchoring cone is fixedly arranged at the lower end of the tamping leg, anchoring rods are hinged to the outer side wall of the lower end of the tamping leg, the anchoring rods are provided with at least two pieces, and the distance between every two adjacent anchoring rods is equal; the rotating axis of the anchoring rods is perpendicular to the center line of the tamping leg, and when the anchoring rods rotate, the center line of the anchoring rods and the center line of the tamping leg are coplanar; and a hollow cavity is formed in the tamping leg, a lifting piece is fixedly arranged at the end, hinged to the tamping leg, of each anchoring rod, and a lifting device used for driving the lifting pieces to rotate is fixedly installed in the hollow cavity of the tamping leg. The auxiliarydevice for building supervision has the advantages that surrounding loose soil can be tamped, and the whole measuring foot stand can be stably fixed to the ground.

The invention relates to the technical field of chemical equipment, and discloses an intelligent anti-falling chemical equipment lifting frame. The intelligent anti-falling chemical equipment liftingframe comprises a rack, wherein a control chamber is fixedly connected to the upper side of the rack, limiting rods are fixedly connected to the right sides of second connecting rods, and fifth connecting rods are rotatably connected to the outer sides of second fixing shafts. The upper sides of the fifth connecting rods are rotationally connected with sixth connecting rods, the right sides of thesixth connecting rods are rotationally connected with anti-shaking plates, and the lower sides of first moving blocks are fixedly connected with second chains. According to the intelligent anti-falling chemical equipment lifting frame, the limiting rods are disengaged from tooth grooves in the rack, so that the first moving blocks drive chemical equipment to ascend through the second chains, whenthe chemical equipment ascends to a certain position, a rotating wheel stops rotating, meanwhile, the limiting rods are clamped in the tooth grooves in the rack, the limiting rods can protect the chemical equipment from falling off, and due to the structure, the effects that when the rotating wheel fails, intelligent secondary protection can be performed on the equipment, and safety accidents arenot likely to happen are realized.

The application relates to an auxiliary device for construction supervision, which includes a mounting seat, a tamping leg is fixedly connected to the bottom surface of the mounting seat, an anchoring cone is fixedly arranged at the lower end of the tamping leg, and an anchoring cone is hinged on the outer wall of the lower end of the tamping leg. There are at least two anchor rods, and the distance between two adjacent anchor rods is equal; the rotation axis of the anchor rod is perpendicular to the center line of the tamping leg, and when the anchor rod rotates, the center line of the anchor rod and the tamping The center lines of the legs are coplanar; a hollow cavity is provided inside the tamping leg, a lifting piece is fixedly installed on the hinged end of the anchor rod and the tamping leg, and a lifting device for driving the lifting piece to rotate is fixedly installed in the hollow cavity of the tamping leg. The application has the effect of being able to tamp the surrounding loose soil so that the entire measuring tripod is stably fixed on the ground.
