AI Technical Summary
In the current grain gate, the pressure of the grain piled up inside is directly transmitted to the gate body during use, causing the gate body to deform. There is a lack of effective pressure buffering measures, which affects the storage effect.
A grain-blocking gate structure with a rubber pad and an air bladder was designed. The rubber pad is fixed to the air bladder in the inner groove at the rear end of the gate to buffer the internal pressure. It is supported on the outside by the support column and the fixed seat to enhance the elastic deformation capability of the gate and provide a convenient sampling and testing structure.
The combination of rubber pads and airbags improves the pressure buffering capacity of the grain gate, reduces gate deformation, strengthens the gate's support structure, and facilitates grain sampling and testing.

Description
Technical Field
[0001] This utility model relates to the field of grain storage technology, specifically a grain-blocking door with pressure buffering function. Background Technology
[0002] Grain gates are crucial protective devices at the grain silo outlet, primarily serving the dual functions of resisting pressure and preventing grain spillage, as well as providing a tight seal. Located at the final point of contact for grain flow, they must withstand lateral pressure from the grain pile and prevent accidental leakage. They are commonly used below the unloading openings of flat-roofed warehouses, shallow round silos, or at the junctions of conveyor equipment.
[0003] However, in the actual installation and use of grain gates, the outer side of the main body of the grain gate is mostly in direct contact with the grain inside. The pressure of the grain accumulation inside will be directly transmitted to the gate body, which can easily lead to deformation of the gate body over time. The pressure buffering effect on the stored grain is limited and insufficient. There are no measures to provide auxiliary pressure buffering for the inner side of the grain gate.
[0004] Now, a new type of grain gate with pressure buffer function is proposed to solve the above-mentioned shortcomings. Utility Model Content
[0005] The purpose of this invention is to provide a grain-blocking gate with pressure buffering function to solve the problem mentioned in the background art that it is inconvenient to perform auxiliary pressure buffering on the inside of the grain-blocking gate.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a grain-blocking gate with pressure buffering function, comprising a door frame, a door body one, and a door body two. Door body one is hinged to the left side inside the door frame, and door body two is hinged to the right side inside the door frame. Rubber pads are fixed to the rear ends of door body one and door body two, and several inner grooves are vertically opened inside the front end of the rubber pads. An airbag is vertically fixed inside the inner groove.
[0007] As a further technical solution of this utility model, the plurality of inner grooves are distributed at equal intervals inside the front end of the rubber pad.
[0008] As a further technical solution of this utility model, the front ends of the first door body and the second door body are respectively fixed with a fixing seat, the front ends of the first door body and the second door body are respectively provided with a support column, and the bottom end of the support column is welded and fixed with a base plate, the top end of the support column is welded and fixed with a connector, the left side of the fixing seat is provided with a connecting bolt, and the right side of the fixing seat is provided with a connecting nut.
[0009] As a further technical solution of this utility model, the right side of the connecting bolt passes through the interior of the fixing seat and the connecting head respectively, the connecting nut is threaded to the outside of the connecting bolt, and the mounting bolt is provided through the interior of the base plate.
[0010] As a further technical solution of this utility model, a mounting base is fixed on the left side of the front end of the second door body, and a connection port is fixed on the front end of the mounting base. A screw cap is provided on the front end of the connection port, and the rear end of the mounting base penetrates the interior of the second door body.
[0011] As a further technical solution of this utility model, the outside of the connection port is provided with an external thread, the inside of the cap is provided with an internal thread that mates with the external thread, the cap is threadedly connected to the outside of the connection port, and the connection port communicates with the inside of the mounting base.
[0012] As a further technical solution of this utility model, a number of fixing rings are fixed on the right side of the front end of the first door body and the left side of the front end of the second door body. A threaded sleeve is arranged horizontally between the two sets of fixing rings, and a turntable is fixed at the middle position of the outside of the threaded sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a door body one, a door body two, a rubber pad, an inner groove and air bladders, during the installation and use of the grain blocking door, rubber pads are fixed at the rear ends of door body one and door body two respectively, which can provide padding protection for the rear end of the grain blocking door. When the inside is compressed, the several air bladders installed inside the rubber pad are compressed, which can provide auxiliary buffering and pressure on the rear end of the grain blocking door. Combined with the outer arc structure of door body one and door body two, the overall elastic deformation buffering capacity of the grain blocking door is improved.
[0015] With a gate body one, a gate body two, a fixed seat, a connecting nut, a connector, and a connecting bolt, the grain gate is installed by placing the two sets of support columns with corresponding fixed seats at the front ends of the gate body one and the gate body two. Then, the bottom plate of the support column is fixed to the ground.

[0030] Working Principle: After the grain gate is installed at the grain silo outlet, rubber pads 10 are fixed to the rear ends of both gate body 1 (2) and gate body 2 (8) to provide cushioning and protection. When the inside is under pressure, several airbags 12 installed inside the rubber pads 10 compress, providing auxiliary buffering and pressure relief to the rear end of the grain gate. Combined with the outer arc-shaped structure of gate body 1 (2) and gate body 2 (8), this improves the overall elastic deformation buffering capacity of the grain gate. Simultaneously, during installation and use, two sets of support columns 14 are installed at the front ends of gate body 1 (2) and gate body 2 (8) respectively, corresponding to the fixing seats 3. Then, the bottom plate 15 of the support columns 14 is fixed to the ground. The two sets of front-end support columns 14 provide auxiliary external reinforcement support for the main body of the grain gate. Furthermore, by unscrewing the cap 19 from the outside of the connection port 20 at the front end of the mounting seat 9 on gate body 2 (8), rapid sampling and testing of the internal grain can be performed through the connection port 20 and the mounting seat 9.
