In the prior art, the Chinese patent publication number CN217384913U discloses an electric blast drying oven for environmentally friendly concrete testing, including: a drying oven body, a plurality of holding plates for holding concrete to be tested are installed inside the drying oven body; a drying mechanism is used to provide wind speed and heat inside the drying oven body; a circulation mechanism for circulating the plurality of holding plates is installed inside the drying oven body; a plurality of disassembly mechanisms for disassembling the holding plates are also installed inside the drying oven body, and the circulation mechanism includes four gears, and the four end corners of the drying oven body are all provided with gears, and a cross bar is fixed inside the gear; the utility model uses the circulation mechanism to enable the plurality of holding plates to circulate inside the drying oven body, so that the plurality of holding plates can be subjected to uniform heat and wind speed, and the plurality of holding plates can be tested, so that its testing standard is more in line with the real data.

[0003] During use, the above-mentioned patent uses a crawler to drive a concrete containing plate to circulate, and the containing plate is suspended on the surface of a transverse connecting column fixedly connected to the crawler surface. Under this structure, the horizontality of the containing plate is achieved by its own gravity. In this way, when placing materials on the containing plate, it is necessary to always ensure that the materials on the surface of the containing plate are evenly distributed, otherwise the containing plate will tilt, causing the materials inside the containing plate to gather on one side, and then causing the entire containing plate to expand and tilt, and finally causing the concrete materials inside to fall, which is undoubtedly very difficult. Overall, it still has certain defects in use.

[0004] In addition, when the holding plate is subjected to a slight force, it will tilt and shake, which can easily cause the materials inside the holding plate to gather on one side, thereby causing the entire holding plate to expand and tilt, and eventually causing the concrete materials inside to fall.

[0023] When in use, first open the box door 2, then place the concrete curing agent that needs hot air drying on the surface of the tray 3, and then close the box door 2, start the entire electric hot air drying box to dry and heat the concrete curing agent on the tray 3. In this process, the first guide rod 8 can be driven by the driving component to move inside the first guide groove 7, and the first guide rod 8 will drive the tray 3 to move synchronously, and then drive the tray 3 to move up and down in the box body 1, so that the concrete curing agent on the tray 3 is heated more evenly, and in this process, the second guide rod 10 will also be driven to move synchronously, so that the tray 3 will always maintain its original horizontal state and move up and down in a circular motion, so that the tray 3 can be prevented from shaking or tilting when moving inside the box body 1.

[0024] The driving assembly includes a first synchronous belt 11, the shape and position of the first synchronous belt 11 correspond to the first guide groove 7, and a first connecting seat 12 is fixedly installed on the surface of the first synchronous belt 11.
