Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 , Figure 2 The utility model provides an embodiment: a heat insulation device for a harvester ceiling, comprising a machine room 1, a grid plate 2 is fixedly connected to the upper surface of the machine room 1, support columns 3 are fixedly connected to the four corners of the upper surface of the grid plate 2, insulation cotton 4 is fixedly connected to the top of the four support columns 3, the upper surface of the insulation cotton 4 is fixedly connected to the ceiling 5, the upper surface of the ceiling 5 is fixedly connected to the reflective layer 6, the insulation cotton 4, the ceiling 5 and the reflective layer 6 are of the same size, the upper surface of the grid plate 2 and the lower surface of the insulation cotton 4 are provided with through grooves 7, a plurality of micropores 8 are provided inside the grid plate 2, the micropores 8 are communicated with the through grooves 7, the micropores 8 are communicated with the inside of the machine room 1, and a heat dissipation mechanism is installed inside the grid plate 2.

[0023] Specifically, the heat-insulating cotton 4 can effectively isolate the indoor and outdoor temperatures. The reflective layer 6 is made of a metallized film material with good reflectivity and transmittance, and can effectively reflect the heat from direct sunlight. The through grooves 7 and the micropores 8 are connected to the interior of the machine room 1. The mesh plate 2 and the support column 3 are provided with grooves corresponding to the size of the isolation plate 12 to facilitate the lifting and lowering of the isolation plate 12.

[0024] Referring to 2 , the heat dissipation mechanism includes a first fan 9 , the outer wall of which is installed inside the mesh plate 2 , a second fan 10 is installed inside the mesh plate 2 , and the first fan 9 and the second fan 10 are arranged diagonally.

[0025] Specifically, the first fan 9 blows air from the outside to the inside, and the second fan 10 discharges the indoor air to the outside. The first fan 9 and the second fan 10 are diagonally arranged, so that the air circulation effect is better.

[0026] Reference Figure 3A first mounting groove 11 is provided inside the machine room 1, an isolation plate 12 is installed inside the machine room 1, and the outer wall of the isolation plate 12 is installed inside the first mounting groove 11. Two gears 13 are installed inside the machine room 1, and the two gears 13 are rotatably connected to the inner sides of the first mounting groove 11 through a rotating shaft. A rack 15 is meshed and connected at the teeth of the gear 13. Two mounting plates 14 are installed inside the machine room 1, and the outer walls of the two mounting plates 14 are slidably connected to the inner sides of the first mounting groove 11. The outer wall of the rack 15 is fixedly connected to the surface of the mounting plate 14, the top end of the mounting plate 14 is fixedly connected to the bottom end of the isolation plate 12, and a handle 17 is fixedly connected to one side of the mounting plate 14.

[0027] Specifically, by pushing the handle 17, the mounting plate 14 can slide in the first mounting groove 11, and then the rack 15 drives the gear 13 to rotate, and then the isolation plate 12 can be driven to move up and down. When moving upward, the top of the isolation plate 12 contacts the lower surface of the insulation cotton 4, and after moving downward, it completely enters the interior of the first mounting groove 11, thereby controlling whether the through groove 7 and the micropore 8 are connected to the outside world.

The through groove 7 is set below the heat insulation cotton 4 to effectively reduce the conduction effect of solar radiation heat, keep the machine room 1 warm, and effectively improve the heat insulation effect of the ceiling 5. The micropores 8 inside the mesh plate 2 can realize the indoor and outdoor air circulation. The first fan 9 and the second fan 10 are used to blow air into the room and blow the indoor air out. The air is discharged, thereby increasing the circulation speed of the air, thereby reducing the indoor temperature. By holding the handle 17, the movable block 18 moves to the cavity in the handle 17 while holding the handle 17, thereby pushing the handle 17 to slide in the second mounting groove 16, and then the rack 15 on the mounting plate 14 drives the gear 13 to rotate, and the mounting plate 14 slides in the first mounting groove 11, and then the isolation plate 12 can be moved up and down, so as to control whether the through groove 7 and the micropore 8 are connected with the outside world, so as to control the air circulation between indoor and outdoor, so as to facilitate users to adjust according to seasons or different climate conditions.
