Description

Technical Field

[0001] This utility model relates to the technical field of ventilation windows for grain warehouses, and specifically to a grain warehouse ventilation window with adaptive pressure regulation. Background Technology

[0002] Ventilation is crucial for ensuring grain quality and storage stability during grain storage. Regularly opening windows is an economical and practical ventilation method, allowing natural air circulation to reduce the risk of moisture absorption and mold growth. Grain silos typically have ventilation windows on the top, with their opening and closing determined daily based on temperature and humidity conditions. For example, utility model patent CN205727157U discloses a grain silo ventilation window, which mainly includes a grain silo window frame and the window itself. One side of the window is hinged to the outer frame. The window also includes an electric window opener mounted on a base via a motor, a driving rotating component, a passive rotating rod, and a crank-arm linkage mechanism consisting of a rear drive arm and a front drive arm connected by hinges. The front drive arm pushes a spring to slide the latch, causing the window to close via the hinges. During and after closing, the stress on the window is concentrated on the left side, resulting in uneven stress around the perimeter, which can affect the airtightness. The patent with authorization announcement number CN216690856U discloses a grain depot ventilation window and operating device. The ventilation window body is connected only by an L-shaped connecting plate on one side, resulting in uneven pressure around the perimeter and the other side being prone to poor sealing. Utility Model Content

[0003] The purpose of this invention is to provide a grain storage ventilation window with adaptive pressure regulation to solve the problem of uneven stress on grain storage windows.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adaptive pressure-regulating grain warehouse ventilation window includes a window frame, a window body, and a drive linkage mechanism. The right side of the window body is hinged to the window frame via a hinge. Four clamping parts are provided on the outer side of the window body, and the four clamping parts are evenly distributed in the circumferential direction around the center of the window body.

[0006] The drive linkage mechanism includes a first link, a second link, and a pressure arm assembly. One end of the first link is hinged to one end of the second link, and the other end of the second link is provided with a hinge seat. The pressure arm assembly includes four pressure arms. One end of each pressure arm is hinged to the hinge seat, and the other end is movably connected to the pressing part and can apply force to the pressing part.

[0007] Furthermore, the pressing part is a pressing plate, and the pressing plate is provided with an inclined elongated hole.

[0008] Furthermore, the pressure arm is in an inclined state, and one end of the pressure arm is vertically provided with a pin, which extends into the elongated hole.

[0009] Furthermore, the hinge seat includes a central tube, with hinge tubes connected to its four sides. The hinge tubes are provided with hinge holes for hinged connection of the other end of the pressure arm.

[0010] Furthermore, a positioning tube is provided on the outer side of the window, and the central tube is inserted into the positioning tube and can move along the length direction of the positioning tube.

[0011] Furthermore, one end of the first connecting rod is used to connect to a rotating rod that is vertically installed outside the grain silo.

[0012] Furthermore, a support plate is provided on the inner periphery of the window frame, and an airbag strip is provided on the support plate to press and fit the window when it is closed.

[0013] The beneficial effects of this utility model are:

[0014] The main improvement of this adaptive pressure-regulating grain silo ventilation window lies in the control linkage mechanism of the window body. Four pressing parts are distributed on the outer side of the window body, each corresponding to a pressure arm. Each pressure arm is connected to a hinge seat and subjected to the force of the hinge seat. When the window is closed, the motor actuates, rotating the lever and driving the linkage mechanism, ultimately ensuring that all four pressure arms exert pressure on the pressing parts. This results in multiple distributed pressure points on the outer side of the window body, providing more even pressure and improving the sealing effect after the window is closed. This mechanism is primarily made of profiles and is easy to manufacture and cost-effective. Attached Figure Description

[0021] 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 skilled in the art are within the protection scope of the present utility model.

[0022] Embodiments of this utility model:

[0023] like Figures 1-5 As shown, an adaptive pressure-regulating grain silo ventilation window includes a window frame 1, a window body 2, and a drive linkage mechanism. Both the window frame 1 and the window body 2 are common rectangular structures. Their orientation is defined by their installed state. The right side of the window body 2 is hinged to the window frame 1 through two hinges 3. The hinges 3 allow the window body 2 to rotate along one side to achieve side opening.

[0024] Four clamping parts 21 are provided on the outer side of the window 2. The four clamping parts 21 are evenly distributed around the center of the window 2 in the circumferential direction to provide multiple force application points for more uniform force application.

[0025] The drive linkage mechanism includes a first link 41, a second link 42, and a pressure arm 6 assembly. One end of the first link 41 is hinged to one end of the second link 42, and the other end of the second link 42 is provided with a hinge seat 5. The other end of the first link 41 is used to connect to a rotating rod (not shown) vertically installed outside the grain silo. The rotating rod is existing technology and is rotatably mounted in a rotating seat outside the grain silo. It can rotate under the drive of a geared motor (or a motor in conjunction with a geared transmission mechanism). The forward and reverse rotation of the geared motor can control the opening and closing of the window 2. When the rotating rod rotates, it drives the first link 41 to move in conjunction, and the second link 42 moves accordingly, ultimately driving the window 2 to move.

[0026] The pressure arm 6 assembly includes four pressure arms 6. One end of each pressure arm 6 is hinged to the hinge seat 5, and the other end is movably connected to the clamping part 21 and can apply force to the clamping part 21.

[0027] like Figure 2 and Figure 4 As shown, the hinge seat 5 includes a central tube 52, and hinge tubes 51 are connected to the four sides of the central tube 52. The hinge tubes 51 are provided with hinge holes for hinged connection of the other end of the pressure arm 6. Both the central tube 52 and the hinge tubes 51 are made of rectangular profiles, with notches 53 machined at the ends to allow space for the ends of adjacent tubes to be hinged.

[0028] like Figure 3As shown, the pressing part 21 is a pressing plate, and the pressing plate is provided with an inclined elongated hole 211. The pressing arm 6 is in an inclined state, and one end of the pressing arm 6 is provided with a vertical pin 61, which extends into the elongated hole 211; the other end of the pressing arm 6 is hinged to the corresponding hinge tube 51.

[0029] A positioning tube 22 is provided on the outer side of the window 2. The positioning tube 22 is fixed, and the central tube 52 is inserted into the positioning tube 22 and can move along the length of the positioning tube 22. In this embodiment, both the central tube 52 and the positioning tube 22 are rectangular tubes; in other embodiments, round tubes can also be used. When the window is closed, the second connecting rod 42 drives the central tube 52 to move in the positioning tube 22, while each pressure arm 6 moves in the pressing part 21, with a downward pressing tendency. The pin 61 at the end of the pressure arm 6 applies force to the pressing part 21, thereby applying force to the window 2 (towards the window frame 1), thus achieving a tight seal. Furthermore, the pressure is relatively uniform through the pressure arms 6 distributed on the four sides, resulting in a better sealing effect. Regardless of whether the window is closed or open, the central tube 52 will not come out of the positioning tube 22.

[0030] Furthermore, a buffer spring can be installed in the positioning tube 22 for the central tube 52 to abut against, which can improve the stability of the mechanism during operation.

[0031] As shown in the figure Figure 5 As shown, a support plate is provided on the inner periphery of the window frame 1, and an airbag strip 11 is provided on the support plate to provide a tight fit when the window 2 is closed. The airbag strip 11 is a single piece and can be fixed to the window frame 1 by adhesive. The airbag strip 11 deforms under the pressure of the window 2, thereby improving the sealing fit, and can adapt to different forces within a certain range, facilitating practical adjustment and use. The airbag strip 11 can also be equipped with an inflation nozzle, allowing adjustment of its internal pressure as needed. The airbag strip with an inflation nozzle is existing technology, or it is called an inflatable sealing ring; during installation, the inflation nozzle side faces inward towards the window frame 1 to avoid interference with the window 2, such as by making a perforation in the support plate for the inflation nozzle to be inserted. The height of the airbag strip 11 is lower than the outer side of the window frame 1, i.e., it does not protrude outward.

[0032] Furthermore, the motor can also be equipped with a remote controller for remote control. Alternatively, it can form a linkage control system with pressure and temperature sensors inside the grain silo. When the pressure and temperature sensors reach set thresholds, the motor starts and window 2 opens for ventilation. The ventilation duration can be set, and window 2 automatically closes.
