Abstract
Description
Technical Field
[0001] This application relates to the technical field of dust covers for foldable grain elevators, and in particular to a dust cover for a foldable grain elevator. Background Technology
[0002] In the fields of agricultural production and grain processing, grain elevators, as key equipment for vertical or inclined grain conveying, are widely used in scenarios such as grain warehouse transfer, storage and loading / unloading, and processing lines. Their efficient conveying capacity directly affects the overall efficiency of grain processing. However, during operation, grain elevators easily generate a large amount of dust due to friction and collision between grain particles and contact with equipment components. This dust not only contains grain debris but may also contain soil, impurities, etc., which are released into the surrounding environment in large quantities at the openings of the conveying channel and at equipment connections.
[0003] Dust pollution has long been a prominent problem hindering the use of grain elevators. Firstly, dust pollution severely impacts the quality of the working environment. Operators exposed to high dust levels for extended periods are prone to respiratory illnesses, lung damage, and other health problems, failing to meet occupational health and safety standards. Secondly, the accumulation of large amounts of dust on the equipment surface and surrounding facilities not only increases the difficulty of cleaning and maintenance but can also lead to poor heat dissipation, accelerated wear of components, shortened equipment lifespan, and increased failure rate. Furthermore, some grain dust is flammable; when the concentration reaches a certain threshold, it can explode upon contact with an open flame, posing a significant safety hazard.
[0004] To address the aforementioned issues, various dustproof devices for grain elevators have emerged in the prior art, such as fixed sealing covers and flexible cloth covers. However, fixed sealing covers are typically bulky, difficult to install and disassemble, inconvenient for equipment inspection and maintenance, and poorly suited for elevators that require relocation or adjustment. While traditional flexible cloth covers offer some flexibility, they perform poorly in terms of dustproof sealing and are prone to wear and aging after prolonged use, requiring frequent replacement and increasing operating costs. Therefore, those skilled in the art provide a foldable dustproof cover for grain elevators to solve the problems mentioned in the background section. Utility Model Content
[0005] To address the problems mentioned in the background art, this application provides a foldable dust cover for a grain elevator.

[0008] Preferably, two movable rods are movably installed at the top of the inside of the feed guide plate, and a baffle is fixedly installed on the outside of the movable rods.
[0009] Preferably, three filter plates are fixedly installed inside the dustproof box, and the dustproof box is connected to the inside of the feeding box.

[0019] The illustrative embodiments and descriptions of the present invention are provided herein to explain the invention, but are not intended to limit the invention.
[0020] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0021] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.
[0022] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.
[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0024] like Figs. 1-3As shown, a foldable grain elevator dust cover includes a feeding box 1, a dust cover 3 connected to the upper end of the feeding box 1, a suction fan 4 connected to the upper end of the dust cover 3, an exhaust pipe 5 connected to the air outlet of the suction fan 4, a discharge hopper 2 fixedly installed at the lower end of the feeding box 1, and a feeding guide plate 6 connected to one side of the feeding box 1.
[0025] In this embodiment, two movable rods 9 are movably installed at the top of the inside of the feed guide plate 6, and a baffle 10 is fixedly installed on the outside of the movable rods 9.
[0026] In this embodiment, three filter plates 13 are fixedly installed inside the dustproof box 3, and the dustproof box 3 is connected to the inside of the feeding box 1.
[0027] In this embodiment, the upper end of the dustproof box 3 is provided with an air guide hole 12, and the suction fan 4 is connected to the air guide hole 12.
[0028] In this embodiment, through holes 11 are provided at both the upper and lower ends of the feed guide plate 6, and dustproof frames 7 are fixedly installed at both the upper and lower ends of the feed guide plate 6.
[0029] In this embodiment, the upper end of the dustproof frame 7 is connected to a second hair dryer 8, and the upper end of the second hair dryer 8 is connected to an exhaust pipe 14.
[0030] The implementation principle of the foldable grain elevator dust cover in this application embodiment is as follows: The dust prevention principle of the foldable grain elevator dust cover revolves around the synergistic mechanism of "source dust control + active dust collection + high-efficiency filtration + directional dust discharge". Through the linkage of various components, it achieves full-process control of dust: When grain enters the feeding box 1 through the feed guide plate 6, the dustproof frames 7 at the upper and lower ends of the feed guide plate 6 first form a protective barrier, reducing the direct escape of dust from the edge of the guide plate during the grain's descent. Simultaneously, the blower 8 connected to the upper end of the dustproof frame 7 is activated, using airflow to form an "air curtain" effect, further blocking the outward diffusion of dust. Part of the dust captured by the air curtain is directionally discharged to the designated collection area through the exhaust pipe 14, avoiding dust accumulation near the feed inlet. Dust generated during the descent and collision with the box wall of the grain entering the feeding box 1 will diffuse upwards due to the internal through-structure of the feeding box 1 and the dustproof box 3. At this time, the suction fan 4 at the top of the dustproof box 3 generates negative pressure through the air guide hole 12, actively drawing the dust-laden airflow from the feeding box 1 into the dustproof box 3. The airflow passes through three filter plates 13 in sequence within the dustproof box 3, where multiple layers of filtration intercept dust particles. Larger particles such as grain debris and impurities are initially filtered, while fine dust is deeply adsorbed, ensuring that the cleanliness of the filtered airflow meets emission requirements. Furthermore, the movable rod 9 at the top of the feed guide plate 6 can flexibly adjust the angle of the baffle 10, optimizing the sealing of the feeding channel according to the grain conveying volume, reducing dust leakage from the feed inlet, and preventing grain blockage caused by fixed baffles. Finally, the filtered and purified airflow is discharged through the exhaust pipe 5 from the outlet of the suction fan 4, while the grain is conveyed through the discharge hopper 2 at the bottom of the feeding box 1, achieving synergistic optimization of dust prevention and hoist operating efficiency.
[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.
