Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a circular grain ventilation and sealing valve. Background Technology

[0002] In grain storage, the grain pile heats up due to respiration from the grain itself, microorganisms, and pests, causing the grain temperature to rise. If the grain temperature becomes too high, it will mold and spoil. Therefore, ventilation and cooling are necessary. Currently, existing grain storage technologies use manual opening methods, such as the Chinese utility model patent with publication number CN221228287U, entitled "An Insulated Ventilation Opening Device." While this ensures reliable ventilation, it requires manual opening.

[0003] Therefore, there is an urgent need to develop a circular grain ventilation and sealing valve that is simple in structure and reliable in operation. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a circular grain ventilation and sealing valve. The technical solution adopted by this utility model is as follows:

[0005] A circular grain ventilation and airtight valve is installed on grain storage equipment and provides ventilation communication. It includes a circular airtight valve outer cylinder installed on the grain storage equipment and communicating with the interior of the grain storage equipment, a motor mounting base and a bearing rotation support tube disposed on the side of the circular airtight valve outer cylinder, a motor fixed on the motor mounting base, and a valve core assembly disposed inside the circular airtight valve outer cylinder and connected to the motor and the bearing rotation support tube.

[0006] The valve core assembly includes a rotating shaft with one end sleeved inside the bearing rotation support tube and the other end passing through the motor mounting base and connected to the motor; a circular valve plate disposed inside the outer cylinder of the circular sealed valve; a support frame fixed on the circular valve plate; several crank arms with one end axially connected to the support frame; a connecting pipe fixedly connected to the other end of the crank arms; a limiting connecting plate fixed on the connecting pipe; a connecting lug fixed on the circular valve plate; and a spring connecting the limiting connecting plate and the connecting lug. The connecting pipe is sleeved and fixed on the rotating shaft. The motor drives the rotating shaft and the connecting pipe to rotate, thereby causing the circular valve plate to rotate and open.

[0007] Furthermore, the support frame is rectangular in shape.

[0008] Furthermore, two crank arms are provided, and each is connected to one side of the support frame; a reinforcing connecting beam is provided between the crank arms.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) This utility model sets up a motor mounting base and a bearing rotation support tube, and provides rotation support for the rotating shaft, and uses a motor to drive the rotation, so its operation is reliable.

[0011] (2) This utility model achieves ventilation opening by setting up a circular valve plate, support frame, crank arm, reinforcing connecting beam and connecting pipe, and rotating under the drive of motor with the inner wall of the outer cylinder of the circular sealed valve as the guide.

[0012] (3) By setting a limiting connecting plate, connecting ear and spring, when the device is opened, the spring pulls the circular valve plate to fit tightly against the limiting connecting plate, and the circular valve plate is fixed in position after it is opened.

[0013] In summary, this utility model has the advantages of simple structure and reliable operation, and has high practical and promotional value in the field of grain storage technology. Attached Figure Description
