The mobile base 1 is embedded with the wire groove 101, the fixed shell 2 is rotatably arranged above the mobile base 1, and a rotating wire mechanism for facilitating the rotation of the fixed shell 2 and a thermal insulation mechanism for facilitating heating and heat preservation inside the greenhouse are respectively arranged above the mobile base 1.

[0022] Reference Figure 1-4 In this embodiment, the rotating wire mechanism includes: a bearing 201, a hollow wire rod 202, a wire control cabinet 203, a U-shaped block 3, a side protection plate 301 and an elastic L-shaped embedded block 302;

[0023] A bearing 201 is embedded under the fixed shell 2, and a hollow conductor rod 202 is embedded in the inner ring of the bearing 201. A wire control cabinet 203 is installed on one side of the mobile base 1 through a connecting plate. The other end of the hollow conductor rod 202 is located inside the wire groove 101 set above the mobile base 1. The hollow conductor rod 202 is used to guide the wires inside the fixed shell 2, thereby preventing the internal wires of the fixed shell 2 from being affected when the fixed shell 2 rotates. U-shaped blocks 3 are embedded at both ends of the side of the fixed shell 2, and a side protection plate 301 is movably provided on one side of the U-shaped block 3. An elastic L-shaped embedded block 302 is provided on one side of the side protection plate 301. The U-shaped block 3 and the elastic L-shaped embedded block 302 are movably fitted, and the U-shaped block 3 and the elastic L-shaped embedded block 302 are installed by fastening bolts. The fitting setting between the U-shaped block 3 and the elastic L-shaped embedded block 302 can conveniently install and disassemble the side protection plate 301, thereby facilitating the maintenance and installation of the components inside the fixed shell 2.

[0024] Reference Figure 1-4 In this embodiment, the heat preservation mechanism includes: a fixing plate 4, a PTC electric heating block 401, a mounting plate 5, a driving motor 501, a rotating rod 502, a fan plate 503, an air outlet 6, an exhaust fan 601, a positioning plate 602 and a rotating air guide plate 603;

[0025] A fixed plate 4 is fixedly installed inside the fixed shell 2, and a PTC electric heating block 401 is fixedly installed inside the fixed plate 4. A mounting plate 5 is fixedly installed on one side of the fixed shell 2, and a driving motor 501 is fixedly installed on one side of the mounting plate 5. A rotating rod 502 is installed on one side of the driving motor 501 through its own output shaft, and fan plates 503 are fixedly installed on both sides of the rotating rod 502. An air outlet tube 6 is integrally arranged on one side of the fixed shell 2, and an exhaust fan 601 is fixedly installed inside the air outlet tube 6. A positioning plate 602 is installed on one side of the air outlet tube 6 through a fastening bolt, and a rotating air guide plate 603 is installed inside the positioning plate 602 through a spherical damping rotating shaft. There are multiple groups of rotating air guide plates 603, and the direction of the air outlet is adjusted by the rotating air guide plates 603.

[0026] Reference Figure 1-4 In this embodiment, the PTC electric heating block 401, the drive motor 501, and the exhaust fan 601 are all connected to the power supply inside the wire control cabinet 203 through wires, and the wires of the PTC electric heating block 401, the drive motor 501, and the exhaust fan 601 pass through the hollow wire rod 202.

[0027] Working principle: First, the user passes the wire inside the fixed shell 2 through the hollow wire rod 202 and then passes it out through the wire groove 101 set on the side of the mobile base 1. After passing it out, the user connects the wire inside the fixed shell 2 to the power supply inside the wire control cabinet 203. After the connection is completed, when the device is in use, the staff turns on the PTC electric heating block 401, thereby making the PTC electric heating block 401 heat up. During the heating process of the PTC electric heating block 401, the driving motor 501 is turned on to rotate the rotating rod 502 set at one end at the same time. When the rotating rod 502 rotates, the fan plate 503 fans the heat emitted by the PTC electric heating block 401, thereby blowing out the heat. At the same time, the exhaust fan 601 is turned on to use the exhaust fan 601 to blow the PTC electric heating block 401 The generated heat is drawn out and then discharged through the air outlet 6. During the discharge process, the user can move the direction of the rotating air guide plate 603 according to his own needs, and then adjust the direction of the blown hot air to prevent the hot air from blowing vertically to the crops. At the same time, when the user needs to adjust the direction of the air outlet 6, he can rotate the fixed shell 2 in conjunction with the bearing 201. At the same time, when it is necessary to repair the components inside the fixed shell 2, since the U-shaped block 3 and the elastic L-shaped embedded block 302 are movably fitted, and the U-shaped block 3 and the elastic L-shaped embedded block 302 are installed by fastening bolts, the fitting setting between the U-shaped block 3 and the elastic L-shaped embedded block 302 can be used to conveniently install and disassemble the side protection plate 301, which is convenient for repairing and installing the components inside the fixed shell 2.
