Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a square 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 square grain ventilation and sealing valve that is simple in structure and reliable in operation. Utility Model Content

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

[0005] A square grain ventilation and airtight valve is installed on grain storage equipment and provides ventilation communication. It includes a square airtight valve shell installed on the grain storage equipment and communicating with the interior of the grain storage equipment, a motor mounting base fixed on one side of the square airtight valve shell, a rolling bearing seat fixed on the other side of the square airtight valve shell and coaxially arranged with the motor mounting base, a motor fixed on the motor mounting base, a first circular hole opened in the lower part of the square airtight valve shell, and a valve core assembly disposed in the square airtight valve shell and connected to the motor and the rolling bearing seat.

[0006] The valve core assembly includes a rotating shaft with one end fitted inside a rolling bearing housing and the other end passing through a motor mounting base and connected to a motor; a circular valve plate housed inside a square sealed valve housing and matching a first circular hole; a support frame fixed to 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 each crank arm; a limiting connecting plate fixed to the connecting pipe; a connecting lug fixed to the circular valve plate; and a spring connecting the limiting connecting plate and the connecting lug. The connecting pipe is fitted and fixed to the rotating shaft. The motor drives the rotating shaft and 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] Furthermore, a second circular hole is provided on the top of the square sealed valve housing.

[0010] Furthermore, an inspection door is provided on the outer shell of the square airtight valve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) This utility model sets up a motor mounting base, a rolling bearing seat, a motor and a rotating shaft, uses the motor to drive the rotating shaft to rotate, and uses the motor mounting base and the rolling bearing seat to provide rotational support, which is reliable.

[0013] (2) This utility model sets up a circular valve plate, a support frame, a crank arm, a reinforcing connecting beam and a connecting pipe. Under the drive of the motor, the circular valve plate is rotated and pulled by the spring and the limiting connecting plate to ensure its reliable operation.

[0014] (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.

[0015] 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
