Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain management equipment technology, specifically a damage-resistant grain management system. Background Technology
[0002] After harvesting and drying in autumn, grains need to be transferred to grain storage silos for long-term storage. For tall storage facilities such as large vertical silos and shallow circular silos, traditional loading methods often employ a top-mounted vertical feeding mode, relying on the material's own weight to complete the stacking within the silo. However, for oilseed crops like soybeans, which have large grain diameters and thin, brittle seed coats, after a free fall from a height of 20-30 meters, their terminal velocity can reach 15-22 m / s. Upon impact with the rigid structure of the silo bottom, this generates impact loads as high as 3000-5000 N, resulting in a seed coat mechanical damage rate exceeding 8%. This not only causes a 3%-5% direct mass loss but also alters the internal biochemical characteristics of the grain, severely affecting subsequent processing quality and seed value. Therefore, to reduce seed breakage and loss, it is urgent to design structures that prevent seed breakage. Utility Model Content
[0003] This utility model provides a grain storage tube designed to prevent breakage. This addresses the issue mentioned in the background art where soybeans and other oilseed crops, characterized by large grain size and thin, brittle seed coats, experience impact loads exceeding 3000-5000N upon impact with the rigid structure of the storage silo after a free fall from a height of 20-30 meters. This results in a direct mass loss of 3%-5% and alterations in the internal biochemical properties of the grain, severely impacting subsequent processing quality and seed value.
[0004] To address the existing problems, this utility model provides a grain pipe designed to prevent breakage, including an installation plate. Both ends of the installation plate are connected to L-shaped plates, and the bent sections of the L-shaped plates are connected to cover plates. A feeding cylinder is connected to the side of the cover plate away from the L-shaped plates. A buffer plate is fixedly connected to the inner wall of the feeding cylinder, and several discharge ports are opened on the side wall of the feeding cylinder opposite to the cover plate.
[0005] Furthermore, the bent section is provided with mounting holes a.
[0006] Furthermore, the cover plate has several mounting holes b on its surface near both ends.
[0007] Furthermore, both ends of the feeding cylinder are integrally formed with bent edges, and multiple mounting holes c are provided on the bent edges.
[0008] Furthermore, the cover plate and the feed cylinder are fixed by threaded connectors in the mounting holes b and c.
[0009] Furthermore, the L-shaped plate is fixed by threaded pairs installed in mounting holes a, b, and c.
[0010] Furthermore, the buffer plate includes a connecting plate and a baffle integrally formed at an angle. The connecting plate has a mounting hole d, and the side wall of the feed cylinder has a mounting hole e corresponding to the mounting hole d. The connecting plate is fixed by installing threaded pairs in the mounting holes d and e.
[0011] Furthermore, the buffer plate is located above the discharge port.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the design of a multi-layered buffer plate structure, causes inelastic collisions between the seeds and the buffer plate as they fall through the feeding cylinder. By progressively weakening the normal velocity component of the seeds, a kinetic energy gradient dissipation mechanism is formed, effectively mitigating the impact of the grains on the bottom of the grain storage silo. Compared to traditional direct-fall feeding methods, this technical solution can significantly reduce the risk of seed coat breakage due to high-speed impact, and reduce grain quality loss during transportation.
[0014] 2. This utility model, by setting a discharge port, allows seeds to not only accumulate at the bottom of the grain storage silo in the area corresponding to the feeding pipe, but also to disperse the seeds to other areas at the bottom of the grain storage silo during their descent. This structural design promotes a more uniform increase in seed accumulation height within the grain storage silo, forming a more gently sloping top accumulation shape, thereby optimizing the utilization rate of the internal space of the grain storage silo.
[0015] 3. This utility model, by setting mounting holes a, b, c, d, and e, enables the rapid assembly and disassembly of the L-shaped plate, cover plate, material discharge cylinder, and buffer plate through modular assembly. Compared with traditional welding processes, it reduces a significant amount of on-site installation time, and the components are easy to disassemble and replace if damaged.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-6 A type of anti-breakage grain pipe includes an installation plate 1. Both ends of the installation plate 1 are connected to L-shaped plates 2. The bent section 201 of the L-shaped plate 2 is connected to a cover plate 3. The side of the cover plate 3 away from the L-shaped plate 2 is connected to a feeding cylinder 4. A buffer plate 5 is fixedly connected to the inner wall of the feeding cylinder 4. Several discharge ports 6 are opened on the side wall of the feeding cylinder 4 opposite to the cover plate 3.
[0025] Among them, the bending section 201 has a mounting hole a2011.
[0026] Among them, the surface of the cover plate 3 near both ends is provided with several mounting holes b301.
[0027] Both ends of the feeding cylinder 4 are integrally formed with bent edges 401, and multiple mounting holes c4011 are opened on the bent edges 401.
[0028] The cover plate 3 and the feed cylinder 4 are fixed by threaded connectors (not shown in the attached drawings) in the mounting holes b301 and c4011.
[0029] The L-shaped plate 2 is fixed by a threaded pair (not shown in the attached figure) installed in mounting holes a2011, b301 and c4011.
[0030] The buffer plate 5 includes a connecting plate 501 and a baffle 502 integrally formed at an angle. The connecting plate 501 has a mounting hole d5011, and the side wall of the feed cylinder 4 has a mounting hole e402 corresponding to the mounting hole d5011. The connecting plate 501 is fixed by installing a threaded pair (not shown in the attached figure) in the mounting hole d5011 and the mounting hole e402.
[0031] It should be noted that a rubber layer is provided on the surface of the baffle 502 that comes into contact with the fallen seeds. Alternatively, other flexible materials can be selected as the surface layer to further cushion and protect the fallen seeds.
[0032] Among them, the buffer plate 5 is located above the discharge port 6.
[0033] Working Principle: During use, the anti-breakage grain pipe is installed inside the grain storage silo via the mounting plate 1. When storing seeds in the silo, the seeds are poured in from the top of the feeding cylinder 4. The seeds then fall through the space between the feeding cylinder 4 and the cover plate 3. As the seeds pass through the buffer plate 501, their movement changes to an inclined path. Some seeds are discharged from the discharge port 6 below the buffer plate 501, scattering and falling to the bottom of the grain storage silo. The remaining seeds, after changing direction, continue falling along the feeding cylinder 4, contacting the next buffer plate 501 where their energy is buffered and reduced. Some seeds continue to be discharged from the discharge port 6 below the buffer plate 501, while others continue falling along the feeding cylinder 4 until all seeds have fallen to the bottom of the grain storage silo. During the seed descent, the normal velocity component of the seeds is gradually weakened, forming a kinetic energy gradient dissipation mechanism. This effectively mitigates the impact of the seeds on the bottom of the grain storage silo, preventing the seed coat from cracking and being damaged due to the direct impact of the seeds falling from the feeding cylinder 4 to the bottom of the silo.
