Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a heat preservation and ventilation port for grain storage. Background Art

[0002] During grain storage, due to the respiration of the grain itself, microorganisms, pests, etc., the grain pile generates heat, causing the temperature of the grain to rise. If the temperature of the grain is too high, it will lead to mildew and deterioration of the grain. Therefore, it is necessary to ventilate and cool the grain. In addition, in winter and when the weather is cold, it is necessary to carry out heat preservation treatment for grain storage. At present, the ventilation in the prior art is carried out by a fan. However, when heat preservation is required, the ventilation port is manually blocked, and the operation is rather laborious. Content of the Utility Model

[0003] In view of the above problems, the purpose of the utility model is to provide a heat preservation and ventilation port for grain storage. The technical scheme adopted by the utility model is as follows:

[0004] A heat preservation and ventilation port for grain storage is arranged on the wall of the grain storage. It includes a ventilation pipe penetrating through the wall of the grain storage, a lower bottom plate arranged at the outer end of the ventilation pipe and communicated with the ventilation pipe, a hinge assembly with one end arranged on the ventilation pipe or the lower bottom plate, a sealing cover plate connected to the other end of the hinge assembly, an electric actuator fixed on the wall of the grain storage and close to the side where the hinge assembly is installed, a toggle arm assembly connected between the electric actuator and the sealing cover plate and driving the sealing cover plate to open and close, a connecting ear arranged on the side of the sealing cover plate far from the hinge assembly, and several locking buckles arranged between the lower bottom plate and the sealing cover plate and on the side far from the hinge assembly; the connecting ear is connected with the toggle arm assembly.

[0005] Further, an electric actuator mounting bracket is arranged between the wall of the grain storage and the electric actuator.

[0006] Further, the electric actuator mounting bracket is in a shape of "Ji".

[0007] Further, the hinge assembly includes a rear hinge connecting seat fixed on the ventilation pipe or the lower bottom plate, and a front hinge connecting seat fixed on the side edge of the sealing cover plate and hinged with the rear hinge connecting seat.

[0008] Further, the toggle arm assembly includes a first toggle arm with one end connected to the electric actuator, and a second toggle arm with one end hinged to the other end of the first toggle arm and the other end connected to the connecting ear.

[0009] Further, a sealing ring is arranged on the lower bottom plate; the sealing ring is placed between the lower bottom plate and the sealing cover plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) The utility model provides a lower base plate and a blocking cover plate that are hingedly connected, and uses an electric actuator, a first crank arm, a second crank arm and a connecting ear to drive the blocking cover plate to open and close, thereby ensuring that the vent opening and closing actions are reliable.

[0012] (2) The utility model uses a lock buckle to manually lock the blocking cover when it is necessary to close the blocking cover and temporarily do not need to be opened. In addition, after the utility model uses the lock buckle to lock the blocking cover, the force on the electric actuator and the crank arm assembly is reduced, ensuring the closing reliability.

[0013] (3) The utility model provides a sealing ring between the lower base plate and the blocking cover plate to ensure the reliability of thermal insulation sealing.

[0014] In summary, the utility model has the advantages of simple structure and reliable operation, and has high practical value and promotion value in the field of grain storage technology. BRIEF DESCRIPTION OF THE DRAWINGS
