Specific implementation mode
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The implementation modes of the present invention include but are not limited to the following embodiments.
[0028] Embodiment 1:
[0029] As Figures 1-6 shown, the grain storage warehouse door device provided by the present invention includes: a door frame 1, the door frame 1 is installed inside the entrance and exit of the grain storage warehouse, and an ordinary door is installed on its outer side. A plurality of door leaves 2 are installed in layers on the left and right sides of the door frame 1. A connection mechanism is provided between the door leaf 2 and the door frame 1. The connection mechanism includes a positioning pipe 3 installed on the door frame. A pin rod 4 adapted to the positioning pipe 3 is installed on the door leaf 2. The pin rod 4 is inserted into the positioning pipe 3 from above, so that the door leaf 2 is inserted and installed on the door frame 1, and the door leaf 2 can rotate horizontally with the pin rod 4 as the axis, so that the door leaf 2 opens inward. An inclined docking surface 5 is provided on one side of the door leaf 2, and an insertion hole 6 is provided on the inclined docking surface 5. A sealing plate 7 is installed at the bottom (inward side) of the door leaf 2. When in use, according to the grain storage height in the grain storage warehouse, a certain number of layers of door leaves 2 are selected for installation. At first, only the bottommost Just use the door leaves 2 of the first layer. The door leaves 2 of the first layer include two pair of opening door leaves 2. As the height of stored grain increases, the number of layers of the door leaves 2 is gradually increased. Rotate the two door leaves 2 of the same layer so that they rotate around the pin rod 4, and make the inclined docking surfaces 5 of the two door leaves 2 of the same layer approach each other until they fit. Insert a steel pipe or other similar tool into the insertion hole 6 to connect and fix the two door leaves 2. Since the inclined docking surfaces 5 of the two door leaves 2 fit completely without gaps, it can prevent grain leakage. In addition, the door leaves 2 of the upper layer are also connected and fixed, and the sealing plate 7 at the bottom of the upper layer of door leaves 2 blocks the gap between the upper and lower layers of door leaves 2, thereby preventing grain leakage. Similarly, the gap between the sealing plate 7 of the door leaves 2 of the bottom layer and the ground is small, and the grain cannot leak either, thereby making the sealing performance of the entire protective door better. At the same time, after the two door leaves 2 of the same layer are rotated and docked, an angle similar to a "V" shape is presented between the two door leaves 2. Specifically, as shown in Figure 1 As shown, when the grain in the grain depot presses on the door leaves 2, the two door leaves 2 arranged in a "V" shape can disperse the force to both sides, reducing the frontal force on the door leaves 2, so that the door leaves 2 are not easily damaged and it is not easy to cause the protective door to be squeezed and broken, resulting in grain pouring out of the depot, and grain safety incidents and personnel safety incidents. It should be noted that the inner stress surface of the door leaves 2 is not necessarily a plane and can be designed into a curve shape similar to a parabola, so that after the two door leaves 2 are docked, an arched surface is formed, thereby further improving the structural stability of the door leaves 2.
[0030] By providing a door frame 1, multiple layers of door leaves 2 and a connection mechanism, it is convenient to independently select the number of installed layers of the door leaves 2 according to the amount of grain in the grain storage warehouse. Each layer of door leaves 2 can be rotated and disassembled independently, making it more labor-saving. By providing an inclined docking surface 5 on the door leaves 2 and installing a sealing plate 7, the sealing performance of the device can be improved, the stability of the device can be improved, and it can be prevented that the door leaves 2 are squeezed and broken, resulting in grain pouring out of the depot, leading to grain safety incidents and personnel safety incidents.
[0031] Embodiment 2:
[0032] As shown in Figure 3 As shown, a sealing strip 8 is installed on one side of the inclined docking surface 5 of the door leaves 2. When the two door leaves 2 are docked, the two inclined docking surfaces 5 are slowly pressed together and squeeze the sealing strip 8. The sealing strip 8 is deformed by extrusion, so that the gap between the two inclined docking surfaces 5 is filled densely, and the grain cannot flow out through this gap.
[0033] By installing a sealing strip 8 on one side of the inclined docking surface 5, it is convenient to fill the gap between the two door leaves 2 with the sealing strip 8, improving the sealing performance of the device.
[0034] Embodiment 3:
[0035] As shown in Figures 3-4As shown in the figure, the door leaf 2 is provided with limiting holes 9 penetrating through the upper and lower parts. The aperture of the limiting holes 9 is the same as that of the insertion holes 6. And a bolt 10 is inserted and installed in the limiting holes 9. When in use, when the door leaf 2 is opened, the bolt 10 is inserted into the limiting hole 9 in the middle of the door leaf 2. When the two door leaves 2 are butted and closed, the insertion holes 6 of the two door leaves 2 are aligned. Pull out the bolt 10 in the limiting hole 9 and insert the bolt 10 into the insertion hole 6, then the two door leaves 2 can be connected. In addition, when the upper and lower door leaves 2 need to rotate synchronously, the bolt 10 can be inserted into the aligned limiting holes 9 of the upper and lower two door leaves 2 close to each other, so that the upper and lower two door leaves 2 are connected to form a whole and can rotate synchronously. Furthermore, when the height of the grain in the grain storage bin is relatively high and multiple layers of door leaves 2 are needed for blocking, the multiple layers of door leaves 2 on one side can rotate synchronously, which is convenient for opening and closing the grain storage bin. Specifically as Figure 4 shown.
[0036] By providing limiting holes 9 with the same aperture as the insertion holes 6 on the door leaf 2 and installing bolts 10 in the limiting holes 9, it is convenient to connect the door leaves 2 on the same layer and can conveniently drive the multiple layers of door leaves 2 on the same side to rotate synchronously, which is convenient for opening and closing the grain storage bin.
[0037] Embodiment 4:
[0038] As Figures 1-2 shown, a sealing top 11 is installed on the inner side of the door frame 1. When the door leaf 2 rotates to close the warehouse door, a seal is maintained between the sealing top 11 and the topmost door leaf 2, so that the grain cannot overflow from the top of the door leaf 2.
[0039] By installing a sealing top 11 on the inner side of the door frame 1, the sealing performance of the device can be improved, so that the grain cannot overflow from the top of the door leaf 2.
[0040] Embodiment 5:
[0041] As Figures 5-6 shown, in actual use, in order to prevent the grain in the grain storage bin from collapsing and blocking the door, the grain presses against the door leaf 2 from the inside. Since the door leaf 2 opens inwards and cannot be directly opened, a grain discharge port 12 is provided on the door leaf 2, and a blocking plate 14 is installed on the outside of the grain discharge port 12. The outside of the grain discharge port 12 is blocked by the blocking plate 14, and a handle is installed on the blocking plate 14. When the grain blocks the door, the blocking plate 14 is removed, and equipment such as a screw conveyor can be inserted into the grain storage bin through the grain discharge port 12 to discharge the blocked grain, so that the door leaf 2 can be pushed open.
[0042] By providing a grain discharge port 12 on the door leaf 2 and installing a blocking plate 14, it is convenient to discharge the blocked grain and convenient to open the door leaf 2.
[0043] Embodiment 6:
[0044] AsFigure 6 As shown, a U-shaped insertion frame 13 is installed on one side of the door leaf 2, and the sealing plate 14 is inserted into the insertion frame 13. Specifically, a card slot is provided inside the insertion frame 13, and both sides of the sealing plate 14 are inserted into the card slot from top to bottom, so that the sealing plate 14 is inserted into the insertion frame 13, and then the sealing plate 14 is connected to the door leaf 2.
[0045] By installing the insertion frame 13 on one side of the door leaf 2, it is convenient to connect the sealing plate 14 to the door leaf 2, and it is convenient for the installation and disassembly of the sealing plate 14.
[0046] Working principle: During use, according to the grain storage height in the grain storage warehouse, a certain number of layers of door leaves 2 are selected for installation. At the beginning, only the bottommost door leaf 2 is needed. One layer of door leaf 2 includes two split door leaves 2. As the grain storage height increases, the number of layers of door leaves 2 is gradually increased.
[0047] Rotate the two door leaves 2 of the same layer so that they rotate around the pin rod 4, and make the inclined butting surfaces 5 of the two door leaves 2 of the same layer approach each other until they fit. Insert a steel pipe or other similar tool into the insertion hole 6 to connect and fix the two door leaves 2. Since the inclined butting surfaces 5 of the two door leaves 2 fit completely without gaps, it can prevent grain leakage. In addition, the upper layer of door leaf 2 is also connected and fixed, and the sealing plate 7 at the bottom of the upper layer of door leaf 2 blocks the gap between the upper and lower layers of door leaves 2, thus preventing grain leakage. Similarly, the gap between the sealing plate 7 of the lowermost door leaf 2 and the ground is small, and the grain cannot leak either, so that the sealing performance of the entire protective door is better.
[0048] At the same time, after the two door leaves 2 of the same layer are rotated and butted, an angle similar to a "V" shape is formed between the two door leaves 2. Specifically as Figure 1 shown. When the grain in the grain depot presses on the door leaf 2, the two door leaves 2 arranged in a "V" shape can disperse the force to both sides, reducing the frontal force on the door leaf 2, so that the door leaf 2 is not easily damaged and the protective door is not easily squeezed and broken, preventing grain from pouring out of the depot and avoiding grain safety incidents and personnel safety incidents.
[0049] It should be noted that the inner stress-bearing surface of the door leaf 2 is not necessarily a plane and can be designed into a curve similar to a parabola, so that after the two door leaves 2 are butted, an arched surface is formed, thereby further improving the structural stability of the door leaf 2.
