The utility model relates to the technical field of 3D printing equipment, in particular to a 3D printing concrete layer grain eliminating device which comprises an automatic guided vehicle, a lead screw is rotationally installed at the top of the automatic guided vehicle, an internal thread block is connected to the lead screw in a threaded and sleeved mode, and a limiting mechanism used for limiting the internal thread block is arranged at the top of the automatic guided vehicle. The automatic guided vehicle moves along the 3D printed concrete layer to drive the scraper to move to scrape concrete layer grains of the concrete layer, the scraped concrete can flow downwards along the flow channel on the side face of the scraper, and the concrete flowing downwards along the flow channel can drop into the collecting box. According to the concrete scraping device, scraped concrete can be collected and treated in a unified mode, the situation that when concrete layer lines of a concrete layer are scraped, redundant concrete drips to the surface of the concrete layer below to cause concrete protrusions is avoided, and the concrete can be guided and collected into a collecting box through a flow channel in the side face of a scraping plate.

The utility model discloses a forklift capable of preventing goods from toppling, which relates to the technical field of forklifts, and comprises a forklift body, the surface of the forklift body is fixedly connected with a fixing plate, an adjusting mechanism is arranged in the fixing plate, the adjusting mechanism comprises an adjusting plate and a positioning plate, the middle part of the positioning plate is slidably connected with a clamping rod, and the clamping rod is fixedly connected with the fixing plate. According to the forklift capable of preventing the goods from toppling over, the positioning plate is fixed to the surface of the fixing plate through the clamping rods, then the height of the adjusting plate is fixed, through the extending frame, the goods can be conveniently and rapidly toppled over, and the goods can be conveniently and rapidly toppled over. The positions of the connecting sleeves are fixed, the two connecting sleeves clamp the two sides of goods by moving the extending frame and adjusting the width of the two connecting sleeves, goods of different lengths can be clamped and fixed by sliding the extending plate in the connecting sleeves, and the stability of goods transportation is improved.

The application relates to the technical field of LED floor plug-in lamp connection, and discloses a step-in type LED floor plug-in lamp base connecting piece which comprises a main body and a sliding ring, the bottom of the main body is slidably connected with two plug-in plates, the front and back surfaces of the plug-in plates are both provided with two sliding grooves, the left and right sides of the plug-in plates are both provided with a plurality of tooth grooves, the two plug-in plates can be mutually embedded and combined in a cross shape. When the main body is subjected to eccentric treading, the plug-in plates inserted into the soil can provide reverse resistance support for the main body through the plug-in plates, so that the stability of the inserted position of the plug-in plates in the soil can be ensured, the situation that the main body is tilted and pressed into the ground and the plug-in plates are exposed on the ground after the main body is tilted when the main body is subjected to treading on one side is reduced, the holding force of the soil on the plug-in plates is improved, and the levelness of the main body and the ground and the accuracy of the pointing direction of the spotlight are improved.
