[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-3 and Figure 5 This utility model provides a technical solution: a high-efficiency heat-insulating grain depot sealing door, including a door frame 1 for support, a door panel 2 for closing connected to the front of the door frame 1 by a hinge, a heat-insulating board 4 for heat preservation inside the door panel 2, an opening and closing mechanism 3 for sealing on the inner wall of the door frame 1, and a ventilation mechanism 5 for ventilation inside the door panel 2.

[0029] This high-efficiency heat-insulating grain depot sealing door is installed by fixing the door frame 1 to the wall. The insulation board 4 is made of polyurethane insulation material, which is the best-performing insulation material in the world, thus improving the insulation performance.

[0030] exist Figures 1-3 and Figure 5 In the ventilation mechanism 5, there is a trapezoidal through groove 501 opened on the inner wall of the door panel 2. A filter plate 502 for dust prevention is abutted on the inner wall of the trapezoidal through groove 501. A trapezoidal sealing gasket 503 for sealing is connected to the inner wall of the trapezoidal through groove 501 near the filter plate 502. A trapezoidal block 504 for sealing is abutted on the inner wall of the trapezoidal sealing gasket 503.

[0031] When the trapezoidal block 504 is retracted into the trapezoidal through groove 501, it compresses the trapezoidal sealing gasket 503 to seal the grain depot. When the trapezoidal block 504 rotates out of the trapezoidal through groove 501, outside air is filtered by the filter plate 502 and enters the grain depot for ventilation.

[0032] exist Figures 1-3 and Figure 5In the middle, the front part of the trapezoidal block 504 is connected to a T-shaped frame 505 for support. The T-shaped frame 505 is rotatably connected to the front part of the door panel 2, and a connecting rod 506 is connected through the T-shaped frame 505. The outer side of the connecting rod 506 is rotatably connected to an electric push rod 507 through a bearing. The other end of the electric push rod 507 is rotatably connected to the front part of the door panel 2.

[0033] When the electric actuator 507 is shortened, it pulls the T-shaped frame 505 to rotate, causing the trapezoidal block 504 to rotate out of the trapezoidal through groove 501, opening the trapezoidal through groove 501 for ventilation. When the electric actuator 507 is extended, it causes the T-shaped frame 505 to rotate back to its original position, rotating the trapezoidal block 504 into the trapezoidal through groove 501, compressing the trapezoidal sealing gasket 503, and blocking the trapezoidal through groove 501.

[0034] exist Figure 7 In the filter plate 502, arc-shaped grooves 508 are provided above and below for engaging the arc head plate 511. A cavity 509 for guiding the arc head plate 511 is provided on the inner wall of the trapezoidal through groove 501 near the arc-shaped groove 508. A steel spring 510 for pressing the arc head plate 511 is connected to the inner wall of the cavity 509. The other end of the steel spring 510 is connected to the arc head plate 511 for pressing the arc groove 508. The arc head plate 511 is slidably connected to the inner wall of the cavity 509, and the arc head plate 511 is pressed against the inner wall of the arc groove 508.

[0035] The high-efficiency heat-insulating grain depot sealing door has a rope attached to the filter plate 502. By pulling the rope, the filter plate 502 is pulled out from the trapezoidal groove 501 to clean the dust.

[0036] The steel spring 510 is a spring with high rigidity. The steel spring 510 pushes the arc head plate 511 to slide, pressing the arc head plate 511 against the inner wall of the arc groove 508, and stably supporting the filter plate 502 in the trapezoidal through groove 501.

[0037] exist Figures 1-3 In the middle, the opening and closing mechanism 3 includes a passage 301 opened in the door frame 1 for the passage of hydraulic rod a303 and support arm 304. A sealing box 302 for support is connected to the back of the door frame 1 near the rear of the passage 301. A hydraulic rod a303 for driving the door panel 2 to rotate is rotatably connected to the inner wall of the sealing box 302. The output end of the hydraulic rod a303 is rotatably connected to the support arm 304 for transmission. The support arm 304 is connected to the front of the door panel 2.

[0038] This highly efficient heat-insulating grain depot sealing door uses a sealing box 302 to block the rear end of the opening 301 to prevent air leakage. The shortened hydraulic rod a303 pulls the support arm 304 into the opening 301, and the support arm 304 drives the door panel 2 to rotate and open, assisting in opening the door panel 2. The hydraulic rod a303 is then extended, pushing the support arm 304 to rotate the door panel 2 and close it. When there is a large amount of grain in the grain depot, this assists in opening and closing the door panel 2.

[0039] exist Figures 1-3 and Figure 4 In the middle, the back of the door frame 1 is connected to a hydraulic rod b305 for moving a rectangular frame 306. The output end of the hydraulic rod b305 passes through the inner wall of the door frame 1 and is connected to the rectangular frame 306 for support. The front of the rectangular frame 306 is connected to a sealing ring 307 for sealing, and the sealing ring 307 abuts against the back of the door panel 2.

[0040] This high-efficiency heat-insulating grain depot sealing door extends the hydraulic rod b305, causing the rectangular frame 306 to push the sealing ring 307 against the back of the door panel 2. When the rectangular frame 306 wears down or loses elasticity after prolonged use, it presses the sealing ring 307 tightly against the door panel 2, improving the sealing performance.
