Description

Technical Field

[0001] This utility model relates to the field of grain retaining boards, specifically a high-strength, quick-installation grain retaining board. Background Technology

[0002] Grain retaining walls are specialized panels used in grain silos or grain storage facilities to separate, enclose, or secure grain piles. They are typically made of metal, wood, or high-strength plastic. Their core function is to prevent grain from collapsing, shifting laterally, or becoming mixed during storage due to stacking pressure or external forces, ensuring the stability of the grain pile and storage safety. Metal grain retaining walls are mostly made of galvanized steel, which is rust-resistant and durable; wooden grain retaining walls are lightweight and easy to process, but require moisture and corrosion protection; plastic grain retaining walls combine lightweight and corrosion resistance. Some designs also include slots or connectors for quick assembly into temporary grain silos or partition walls.

[0003] For example, application publication number CN115606408A discloses a special grain retainer assembly for grain silos, including a grain retainer and a mounting base. The mounting base has two rows of pin holes on one side and guide holes on the other side, with the guide holes and pin holes connected by a conical hole. A guide post is fitted into the guide hole with clearance. The end of the guide post near the pin hole is a frustum structure, with several through holes on the sidewall of the conical surface, each containing a ball bearing. A strip plate is connected to the mounting base, and a driving component is connected to the strip plate to push the guide post towards the pin hole. Two rows of pins are connected to the side of the grain retainer for inserting the pins into the guide post through the pin holes, and the pins are clamped and fixed by the ball bearings. This invention achieves the installation and fixation of the grain retainer by cooperating between the pins of the grain retainer and the guide posts in the mounting base, and by using ball bearings to clamp and fix the pins. This solves the problem of cumbersome installation process and reduced overall installation efficiency of existing grain retainers.

[0004] The aforementioned grain retaining plate does not have a ventilation mechanism. During grain storage, the ventilation system alone cannot effectively ventilate the grain piled inside the grain retaining plate, which makes the grain prone to deterioration due to moisture or high temperature. Therefore, there is an urgent need in the market to develop a high-strength, quick-installation grain retaining plate to help people solve the existing problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4This utility model provides an embodiment of a high-strength, quick-installation grain retainer, comprising a bottom grain retainer 1, a middle grain retainer 101 connected to the upper end of the bottom grain retainer 1, an upper grain retainer 102 connected to the upper end of the middle grain retainer 101, and limiting frames 103 fixedly connected to the lower ends of both the middle grain retainer 101 and the upper grain retainer 102. The upper ends of the bottom grain retainer 1 and the middle grain retainer 101 are respectively inserted into the limiting frames 103 at the lower ends of the middle grain retainer 101 and the upper grain retainer 102. H-shaped fixing posts 10 are provided on both sides of the rear ends of the bottom grain retainer 1, the middle grain retainer 101, and the upper grain retainer 102. 6. The bottom grain retaining plate 1, the middle grain retaining plate 101, and the top grain retaining plate 102 are all fixedly connected to the two H-shaped fixing posts 106 on both sides by multiple bolts 107. The bottom grain retaining plate 1 is fixed to the two H-shaped fixing posts 106 first. Then, the middle grain retaining plate 101 and the top grain retaining plate 102 are stacked on top of the bottom grain retaining plate 1. The bottom grain retaining plate 1, the middle grain retaining plate 101, and the top grain retaining plate 102 are quickly vertically aligned by the insertion structure of the limiting frame 103. The middle grain retaining plate 101 and the top grain retaining plate 102 are then fixed to the H-shaped fixing posts 106 to achieve rapid installation.

[0020] Please see Figure 2 and Figure 3 A rectangular ventilation opening 104 is provided in the middle of the middle layer grain retaining plate 101. A support frame 2 is connected to the rear end of the middle layer grain retaining plate 101 and the rear end of the rectangular ventilation opening 104. A blocking ventilation net 201 is fixedly connected to the middle of the support frame 2. The blocking ventilation net 201 blocks the grain at the rear end of the grain retaining plate and provides ventilation. A rectangular connecting frame 105 is fixedly connected to the front end of the middle layer grain retaining plate 101 and the front end of the rectangular ventilation opening 104. A suction fan 3 is connected to the front end of the rectangular connecting frame 105. When the grain silo needs ventilation, the suction fan 3 draws air from between the grains inside the grain silo through the blocking ventilation net 201, preventing the grain piled up at the rear end of the grain retaining plate from deteriorating due to poor ventilation.

[0021] Please see Figure 2 and Figure 4 The supporting frame 2 and the rear end face of the middle grain retaining plate 101 are fixedly connected by multiple first screws 203. The upper and lower ends of the middle part of the supporting frame 2 and the front end face of the blocking ventilation net 201 are both fixedly connected with anti-bending support rods 202. The rear end of the suction fan 3 is fixedly connected with a connecting plate 301. The connecting plate 301 and the rectangular connecting frame 105 are fixedly connected by multiple second screws 302. The front end of the blocking ventilation net 201 is supported by the anti-bending support rods 202 to prevent the blocking ventilation net 201 from deforming due to grain compression.

[0022] Please see Figure 2 and Figure 3The front end of the suction fan 3 is fixedly connected to a fixing ring 303. A U-shaped baffle 4 is provided on the fixing ring 303. A U-shaped slot 401 is provided inside the U-shaped baffle 4. A U-shaped notch 402 is provided between the middle of the rear end face of the U-shaped baffle 4 and the inside of the U-shaped slot 401. The fixing ring 303 is inserted into the U-shaped slot 401 along the lower end of the U-shaped baffle 4 and the front end of the suction fan 3 slides into the U-shaped notch 402. When ventilating, the U-shaped baffle 4 is lifted to disengage from the fixing ring 303, and the suction fan 3 can be turned on for ventilation. On rainy days or when ventilation is not required, the U-shaped baffle 4 is reinstalled to seal the front end of the suction fan 3 to prevent moisture from entering the grain silo through the suction fan 3.

[0023] Working Principle: In use, the bottom grain retaining plate 1 is first fixed between the two H-shaped fixing posts 106 using bolts 107. Then, the middle grain retaining plate 101 and the upper grain retaining plate 102 are vertically stacked above the bottom grain retaining plate 1 through the insertion structure of the limiting frame 103, and fixed to the H-shaped fixing posts 106 with bolts 107 for quick installation. When the grain silo needs ventilation, the U-shaped baffle 4 is pulled upwards to detach from the fixing ring 303, exposing the air inlet of the suction fan 3. After starting the suction fan 3, external air enters the gap between the grain pile through the barrier ventilation net 201, drawing out humid or high-temperature air and achieving effective ventilation of the grain piled inside the grain retaining plate. After ventilation, the fan is turned off, and the U-shaped baffle 4 is reinserted into the fixing ring 303 to seal the air inlet, preventing rainwater or moisture from flowing back in. The bending support rod 202 enhances the compressive strength of the barrier ventilation net 201, preventing the grain pile from being squeezed and deformed, ensuring a long-lasting and stable ventilation effect.
