[0040] See also Figures 1 to 3 The embodiment of the present application provides a window structure, which is arranged on the top wall of the storage bin, and the top wall is provided with an opening connected to the inner cavity of the storage bin. The inner cavity of the storage bin is used for storing materials, and the storage bin may include a surrounding wall that encloses the inner cavity and a top wall that covers the surrounding wall, and the opening is provided on the top wall. It can be understood that when it is necessary to observe the storage situation of the storage bin, the operator needs to stand on the top wall of the storage bin and use a lighting lamp to observe the inner cavity through the opening.

[0041] In an embodiment of the present application, the window structure includes a first cover plate 10 covering the opening and a second cover plate 20 arranged on the side of the first cover plate 10 away from the inner cavity. The first cover plate 10 is provided with a plurality of observation ports 11 connected to the opening. The second cover plate 20 is rotatably or slidably connected to the first cover plate 10 to open the observation ports 11, or is stacked with the first cover plate 10 to cover the observation ports 11.

[0042] It can be understood that the second cover plate 20 can be rotatably connected to the first cover plate 10, so by flipping the second cover plate 20, the observation port 11 can be opened or the second cover plate 20 can be covered on the first cover plate 10, thereby covering the observation port 11. Of course, the second cover plate 20 can also be slidably connected to the first cover plate 10, and a sliding structure is provided between the second cover plate 20 and the first cover plate 10 so that the second cover plate 20 can slide relative to the first cover plate 10, so pushing the second cover plate 20 can cause the second cover plate 20 to be stacked or separated from the first cover plate 10.

[0043] It can be understood that the first cover plate 10 is fixedly connected to the top wall, so that the first cover plate 10 is firmly connected to the top wall, so that the first cover plate 10 can support the weight of the operator, the operator can step on the first cover plate 10, and the first cover plate 10 can be prevented from shifting. The area of ​​the first cover plate 10 can be larger than the cross-sectional area of ​​the opening, so that the first cover plate 10 completely covers the opening, in which case the first cover plate 10 can be fixedly connected to the top surface of the top wall; the area of ​​the first cover plate 10 can also be equal to the cross-sectional area of ​​the opening, in which case the first cover plate 10 is embedded in the opening, and the first cover plate 10 can be fixedly connected to the hole wall of the opening.

[0044] The window structure provided in the present application includes a first cover plate 10 and a second cover plate 20. The first cover plate 10 can cover the opening of the storage bin. At the same time, the observation port 11 opened in the first cover plate 10 allows the operator to observe the inner cavity, thereby reducing the risk of falling from the opening while not affecting the operator's observation of the material storage situation in the storage bin, thereby improving the safety of the operator's observation of the material storage situation in the storage bin, and after the observation is completed, the second cover plate 20 can be covered on the first cover plate 10 to prevent the operator from stepping on the edge of the observation port 11 and spraining his ankle, thereby further improving safety.

[0045] In some embodiments, the first cover plate 10 includes a frame 13 fixed to the inner wall of the opening and a plurality of support rods 12 connected to the frame 13, and the plurality of support rods 12 are arranged in a staggered manner in the area defined by the frame 13 to form a plurality of observation ports 11. The frame 13 can be fixed to the inner wall of the opening by expansion screws, so that the frame 13 can tightly grasp the inner wall of the opening, thereby providing extremely high fixing force and significantly improving safety performance.

[0046] By staggering the support rods 12 in the area defined by the frame 13, multiple observation ports 11 can be formed between the support rods 12 and between the support rods 12 and the frame 13, making the first cover plate 10 lighter, saving materials and costs. In addition, by forming multiple observation ports 11, operators can use lighting to observe the inner cavity through different observation ports 11, thereby expanding the range of observation angles.

[0047] In addition, in the embodiment of the present application, the thickness of the frame 13 along the vertical direction is greater than the thickness of the support rod 12 along the vertical direction, and the end of the support rod 12 is connected to the middle part of the frame 13, that is, the top surface of the support rod 12 will not protrude from the top surface of the frame 13, thereby ensuring that the top surface of the first cover plate 10 is flat, making the second cover plate 20 more firmly covered on the first cover plate 10.

[0048] In some embodiments, the multiple support rods 12 include a plurality of cross rods 121 arranged at intervals and in parallel along a first direction a and a plurality of longitudinal rods 122 arranged at intervals and in parallel along a second direction b. The cross rods 121 and the longitudinal rods 122 are fixedly connected, and the first direction a and the second direction b are arranged at an angle.

[0049] The horizontal bars 121 and the vertical bars 122 are arranged at intervals along the first direction a and the second direction b, respectively, so that the arrangement of the horizontal bars 121 and the vertical bars 122 is more regular, and the distance between two adjacent horizontal bars 121 can be set to be equal, and the distance between two adjacent vertical bars 122 can also be set to be equal, so that the size of each observation port 11 is equal, which is conducive to improving the aesthetics.

[0050] The crossbar 121 and the longitudinal bar 122 may be fixed by welding, thereby improving the connection strength between the crossbar 121 and the longitudinal bar 122 , and also helping to increase the bearing capacity of the crossbar 121 and the longitudinal bar 122 .

[0051] Preferably, the first direction a and the second direction b are perpendicular to each other, that is, each observation port 11 is rectangular in shape. Of course, in other possible implementations, the observation port 11 may also be in other shapes, such as a parallelogram, etc., and the present application does not limit the shape of the observation port 11.

[0052] In some embodiments, the frame 13 includes two first side frames 131 spaced apart from each other and two second side frames 132 connected between the two first side frames 131 . The two first side frames 131 and the two second side frames 132 together form an area for arranging the support rods 12 .

[0053] Specifically, the two first side frames 131 are parallel to each other, the two second side frames 132 are parallel to each other, and the first side frames 131 and the second side frames 132 are perpendicular to each other, that is, the frame 13 in the embodiment of the present application is a rectangular frame 13. Of course, in other possible implementations, the shape of the frame 13 can also be a polygon such as a triangle, a pentagon, or a hexagon, and the present application does not limit the shape of the frame 13.

[0054] Furthermore, the cross-sectional shape of the first side frame 131 and the second side frame 132 is rectangular, and the cross-sectional shape of the support rod 12 is circular. The cross-sectional shape of the first side frame 131 and the second side frame 132 is rectangular, that is, the first side frame 131 and the second side frame 132 are flat plate structures, and the surfaces of the first side frame 131 and the second side frame 132 are planes, so when the first side frame 131 and the second side frame 132 are fixed to the hole wall of the opening, the contact area with the hole wall of the opening is larger, and the hole wall of the opening can be more closely fitted, so that the first side frame 131 and the second side frame 132 are fixed more firmly.

[0055] The cross-sectional shape of the support rod 12 is circular, that is, the support rod 12 is a cylindrical structure. Specifically, the material of the support rod 12 can be round steel. Round steel has high strength and bearing capacity, can withstand large loads and stresses, and is easy to cut, weld and process, which makes it very flexible in construction and machinery manufacturing; the cost of round steel is also relatively low, which has economic advantages in some cases; round steel has good plasticity and toughness, can withstand deformation and extrusion, and is not easy to break; it also has good corrosion resistance. After the surface of the round steel is treated, it can effectively prevent corrosion and oxidation and extend its service life.

[0056] It is understandable that the inner diameter of the observation port 11 cannot be set too large, otherwise the operator may fall from the observation port 11; the inner diameter of the observation port 11 cannot be set too small, otherwise the viewing angle may become smaller, making it inconvenient for the operator to observe the storage conditions. Specifically, the inner diameter of the observation port 11 ranges from 20 cm to 35 cm.

[0057] In some embodiments, a plurality of grid holes 21 arranged in an array are provided on the second cover plate 20, and the heat dissipation performance of the window structure can be improved by providing the grid holes 21. Preferably, the second cover plate 20 is a steel grid, which has the advantages of high strength, light structure, strong corrosion resistance, durability, etc., and has a beautiful appearance, a glossy surface, and is easy to install and disassemble.

[0058] In addition, the inner diameter of the grid hole 21 is smaller than the inner diameter of the observation port 11, so that when the second cover plate 20 is covered on the first cover plate 10, the operator can step on the second cover plate 20 without inserting the foot into the observation port 11 through the grid hole 21, reducing the risk of the operator spraining his ankle.

[0059] In the embodiment of the present application, the first cover plate 10 and the second cover plate 20 are both rectangular structures, and the areas of the first cover plate 10 and the second cover plate 20 are equal, or the area of ​​the second cover plate 20 is slightly larger than the area of ​​the first cover plate 10, thereby ensuring that the second cover plate 20 can cover the observation port 11 when stacked on the first cover plate 10.

[0060] In some embodiments, the second cover plate 20 is rotatably connected to the first cover plate 10 via a hinge 30. The hinge 30 includes a first page 31, a second page 32, and a rotating shaft 33. The first page 31 is fixedly connected to the first cover plate 10, and the second page 32 is fixedly connected to the second cover plate 20. The rotating shaft 33 passes through the first page 31 and the second page 32 so that the first page 31 and the second page 32 can rotate around the rotating shaft 33.

[0061] The present application also proposes a material storage bin, which includes a window structure. The specific structure of the window structure refers to the above embodiments. Since the material storage bin adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The material storage bin includes an inner cavity for storing materials and a top wall corresponding to the inner cavity, and the window structure is arranged on the top wall.

[0062] In some embodiments, the top wall is provided with multiple window structures, and the multiple window structures can be evenly distributed on the top wall. Operators can observe the discharge situation in the storage bin through different window structures, which can increase the observation viewing angle range and reduce the blind spot of vision.

[0063] To summarize, the window structure provided in the present application includes a first cover plate 10 and a second cover plate 20. The first cover plate 10 can cover the opening of the material storage bin. At the same time, the observation port 11 opened in the first cover plate 10 allows the operator to observe the inner cavity, thereby reducing the risk of falling from the opening while not affecting the operator's observation of the material storage situation in the material storage bin, thereby improving the safety of the operator's observation of the material storage situation in the material storage bin, and after the observation is completed, the second cover plate 20 can be covered on the first cover plate 10 to prevent the operator from stepping on the edge of the observation port 11 and spraining his ankle, thereby further improving safety.

[0064] The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
