Description of drawings
Figure 1 shows that the structural representation of the utility model silo automatic ventilation mouth.
Embodiment
In order more to be expressly understood above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with the drawings and specific embodiments the utility model is further described in detail.
A lot of details have been set forth so that fully understand the utility model during description below is concrete; but the utility model can also adopt other to be different from other modes described here and realize; therefore, protection domain of the present utility model is not subjected to the restriction of following public specific embodiment.
Need to prove that under the situation of not conflicting, the application's implementation column and the feature among the embodiment can make up mutually.
As shown in Figure 1, the utility model silo automatic ventilation mouth comprises that sealed door body 1, ventilating opening connect support 2, rocking bar 3, keying kinematic link 4, telescopic electric pushrod 5, motor 6, rocker bracket 7, open and close connecting rod rack 8, electric machine support 9, thermal insulation thermal insulation board 10 and sealing strip 11.
Described ventilating opening connects support 2 and is used for being connected with the original ventilating opening in warehouse.
Described sealed door body 1 is connected support 2 by described rocking bar 3 and connects with described ventilating opening.
Described thermal insulation thermal insulation board 10 is arranged on described sealed door body 1 near the inboard of described ventilating opening connection support 2, and described sealing strip 11 is arranged between described sealed door body 1 and the described thermal insulation thermal insulation board 10.
Described keying connecting rod rack 8 has two, is symmetricly set on described sealed door body 1 outside.
Described telescopic electric pushrod 5, described motor 6 all have two, and described two motors 6 are controlled described two telescopic electric pushrods 5 respectively and done stretching motion, and all are arranged on the described ventilating opening connection support 2 by described electric machine support 9.
Described keying kinematic link 4 has two, include first bar 41 and second bar 42, first end of described first bar 41 all is connected with described sealed door body 1 by described keying connecting rod rack 8, first end of described second bar 42 is connected with described two telescopic electric pushrods 5 respectively, and second end of second end of described first bar 41 and described second bar 42 all is hinged on the described rocking bar 3.
