Description

Technical Field

[0001] This utility model belongs to the field of grain storage technology, specifically relating to a grain storage heat-insulating and sealing door. Background Technology

[0002] Grain warehouses are mainly responsible for receiving, storing, and transporting grain. The warehouse door is an important component of the grain warehouse and must have the function of being airtight and heat-insulating.

[0003] The existing grain gates are all one piece. Due to their structural limitations, they cannot be completely removed, which affects some of the needs when grain is entering and leaving. Some improved detachable grain gates have weak sealing performance, which makes the overall sealing performance of the grain silo worse and causes damage to the grain stored inside. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A grain storage insulated and sealed door, comprising:

[0006] The main gate has side gates connected to both sides.

[0007] A sealing gasket is provided at the connection between the middle door body and the side door body;

[0008] A limiting slot is connected to the wall pier, and the edge of the side door can extend into the limiting slot;

[0009] At least one set of limit rods;

[0010] The limiting slot is provided with at least one set of slots that can cooperate with the end of the limiting rod;

[0011] The middle door body has a stepped groove on its side, which extends along the length of the middle door body, and the side door body is provided with a protruding ridge that conforms to the stepped groove.

[0012] Furthermore, the cross-section of the middle door body is trapezoidal.

[0013] Furthermore, the sealing gasket is disposed on the side of the middle door body and / or the side door body.

[0014] Furthermore, the middle door and the side door are provided with three sets of limiting rods from top to bottom.

[0015] Furthermore, a lock is also provided on the limiting rod.

[0016] Furthermore, the cross-section of the limiting rod is rectangular.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This utility model features a detachable and connectable middle and side door body, equipped with a sealing gasket. By cooperating with the side limiting slot, the sealing door can be disassembled and assembled, adapting to the special requirements for grain storage and handling.

[0019] Because the middle and side gates use stepped grooves and protruding ridges, the two adjacent gates fit together more tightly, ensuring the sealing of the grain gate and making the entire gate structure more stable. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] like Figure 1 - Figure 5 As shown, a grain storage insulation and sealing door of this utility model includes a middle door body 1, a sealing gasket 3, a limiting groove 5, and at least one set of limiting rods 4;

[0030] Both sides of the central door 1 are connected to side doors 2;

[0031] The sealing gasket 3 is installed at the connection between the middle door body 1 and the side door body 2;

[0032] The limiting slot 5 is connected to the wall pier 6, and the edge of the side door 2 can extend into the limiting slot 5;

[0033] The limiting slot 5 is provided with at least one set of slots 50 that can cooperate with the end of the limiting rod 4;

[0034] The middle door body 1 has a stepped groove 10 on its side, which extends along the length of the middle door body 1. The side door body 2 has a protruding ridge 20 that conforms to the stepped groove 10 on its side.

[0035] This utility model features a detachable and connectable middle door 1 and side door 2, equipped with a sealing gasket 3. By cooperating with the side limiting groove 5, the sealing door can be disassembled and assembled, adapting to the special requirements for grain storage.

[0036] Because the middle gate body 1 and the side gate body 2 are fitted with stepped grooves 10 and protruding ribs 20, the two adjacent gate bodies fit more tightly, ensuring the sealing of the grain gate and making the entire gate structure more stable.

[0037] The limiting rod 4 is positioned to limit the front and back of the middle door 1 and the side door 2, and is fixed by inserting the end of the limiting rod 4 into the limiting slot 5.

[0038] Specifically, the cross-section of the middle gate body 1 is trapezoidal.

[0039] Flexible rubber clips are installed near the wall pier 6 on the side door 2 or around the wall pier 6.

[0040] This ensures the airtightness of the grain warehouse's sealed doors;

[0041] Furthermore, the limiting rod 4 set in this technical solution is completely detachable compared to existing grain silo doors. Therefore, there is no need to open grooves or other irregular protrusions on the ground to place the limiting rod 4, which avoids the subsequent conveying equipment affecting the passage when entering and exiting the grain silo. The ground in front of and behind the sealing door of the grain silo using this solution is flat.

[0042] A sealing gasket 3 is installed on the side of the middle door body 1 and / or the side door body 2. The sealing gasket 3 is made of elongated rubber material and can be bonded with adhesive.

[0043] The middle door body 1 and the side door body 2 are equipped with three sets of limiting rods 4 from top to bottom on their sides. This arrangement enhances the stability of the assembled sealed door.

[0044] In addition, a lock is provided at the limit rod 4 and the limit slot 5 (not shown in the figure).

[0045] In this embodiment, the cross-section of the limiting rod 4 can be square, rectangular, or other shapes, and no specific limitation is made here.

[0046] During installation, the middle door 1 can be placed between the two wall jambs 6 first, and then the edges of the two side door 2 can be inserted into the limiting slots 5, while the other edge can fit with the edge of the middle door 1. Then, the limiting rod 4 is used for fixation.

[0047] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
