Description

Technical Field

[0001] This utility model specifically relates to a dust removal device for the walls of grain warehouses, belonging to the technical field of dust removal equipment maintenance. Background Technology

[0002] This utility model specifically relates to a dust removal device for grain warehouse walls, belonging to the technical field of dust removal equipment. As the core location for grain storage, the internal hygiene of grain warehouses directly determines the quality and safety of stored grain. During the process of grain entering, leaving, transferring, and long-term storage, large amounts of dust accumulate on the warehouse walls and ceilings due to scattered grain particles and floating dust. This accumulated dust not only damages the cleanliness of the warehouse but also easily breeds mold and pests, leading to grain spoilage and insect infestation, directly threatening the safety of grain storage. Furthermore, dust accumulation increases the risk of dust explosions within the warehouse, posing a serious safety hazard. Therefore, regular and comprehensive dust removal operations for grain warehouses are necessary.

[0003] Currently, among existing dust removal equipment, such as the "dust removal device for building assembly" disclosed in Chinese utility model patent application number CN202323142240.9, which operates the dust removal hood by hand holding a handle and uses a ventilation structure to remove dust from the walls and top surfaces, although it can meet basic dust removal needs and is relatively easy to operate, it has obvious problems of insufficient adaptability in the specific scenario of grain warehouses.

[0004] The core problem facing this type of handheld dust removal device is its high dependence on manual labor. Grain warehouses are generally characterized by large spaces and high ceilings, making it extremely labor-intensive for people to hold the equipment for extended periods. This not only results in low efficiency but also makes it difficult to cover high walls, ceilings, corners, and other areas, easily creating dust-collecting blind spots. Secondly, its function is limited, only able to remove dust from walls and ceilings, unable to simultaneously handle grain dust scattered on the warehouse floor. This requires additional floor dust removal equipment, increasing operating costs and extending the overall operating time. Furthermore, the precision of manual operation is limited. When working near grain piles, unstable operation can easily lead to dust spreading and contaminating the grain, or collisions with the grain piles can cause grain to scatter, failing to meet the requirements for refined operations in grain warehouses.

[0005] In response to the aforementioned shortcomings of existing technologies in grain warehouse dust removal scenarios, the industry urgently needs a specialized dust removal device that requires minimal manual intervention, can simultaneously remove dust from multiple areas including the ceiling, walls, and floor, and is adaptable to the special operating environment of warehouses. This would improve the efficiency and safety of dust removal in grain warehouses and effectively ensure the quality of grain storage. Utility Model Content

[0031] 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.

[0032] Please see Figures 1-6As shown, the dust removal equipment for the walls of a grain warehouse includes a base plate 1, with a dust collection box 2 fixedly installed near the center of the top of the base plate 1; an exhaust fan 3 connected to one side of the dust collection box 2; a first dust guide pipe 4 fixed to the top of the dust collection box 2, with a clamping pipe 5 fixed to one end of the first dust guide pipe 4; a wall dust removal hood 6 fixedly installed on one end of the clamping pipe 5, and a cleaning assembly 7 installed inside the dust removal hood; and an electric telescopic rod 8 fixedly connected to the top of the base plate 1, with a clamping assembly 9 installed at one end of the electric telescopic rod 8 for clamping. Pipe 5 is clamped horizontally or vertically; Ground dust hood 10 is embedded and positioned inside the equipment base plate 1, and a connector pipe 11 is fixedly installed on the top of the ground dust hood 10; Second dust guide pipe 12 is fixedly installed on the top of the dust collection box 2, and a connecting sleeve 13 is fixedly connected to one end of the second dust guide pipe 12. A sealing ring 14 is bonded to the bottom of the connecting sleeve 13. The connecting sleeve 13 is sleeved on the connector pipe 11, and a positioning flange 15 is formed on the outer side wall of the connecting sleeve 13; Positioning assembly 16 is installed on the top of the equipment base plate 1 and is used to position the positioning flange 15.

[0033] First, adjust the equipment status according to the needs of the area to be dusted: If dust removal is required on the wall, first use the clamping component 9 to horizontally clamp and fix the clamping tube 5 at one end of the first dust guide tube 4 to ensure the connection stability between the wall dust removal hood 6 and the clamping tube 5; then start the electric telescopic rod 8, which will extend and retract according to the required wall dust removal height, bringing the wall dust removal hood 6 and the internal cleaning component 7 closer to the wall surface. At the same time, turn on the exhaust fan 3 and the cleaning component 7. The cleaning component 7 sweeps and peels off the accumulated dust on the wall. Under the negative pressure generated by the exhaust fan 3, the peeled dust enters the clamping tube 5 through the wall dust removal hood 6, and is then transported to the dust collection box 2 through the first dust guide tube 4 for collection. The whole process does not require manual hand operation, effectively reducing labor intensity and accurately covering different height areas of the wall, improving the wall dust removal effect.

[0034] When dust removal is required on the top of the wall, the clamping component 9 is switched to the vertical clamping mode of the clamping tube 5, so that the opening of the wall dust removal hood 6 faces upward; then the electric telescopic rod 8 is extended to push the wall dust removal hood 6 and the cleaning component 7 to a position that fits against the top of the wall. After the exhaust fan 3 and the cleaning component 7 are started, the cleaning component 7 cleans the dust accumulated on the top of the wall. The dust also enters the dust collection box 2 through the wall dust removal hood 6, the clamping tube 5, and the first dust guide tube 4, achieving dust removal without dead corners on the top of the wall, avoiding the safety hazards caused by manual climbing operations, and ensuring the thoroughness of dust removal on the top of the wall.

[0035] When the equipment moves, the ground dust cover 10 is in contact with the ground; the negative pressure of the exhaust fan 3 is transmitted to the second dust guide pipe 12 through the dust collection box 2. The second dust guide pipe 12 is connected to the connector pipe 11 through the connecting sleeve 13 with the sealing ring 14. After the dust on the ground is sucked in, it enters the dust collection box 2 through the connector pipe 11, the connecting sleeve 13, and the second dust guide pipe 12, so as to realize the synchronization of displacement and dust removal and improve the overall efficiency.

[0036] Electric wheels 17 are fixedly connected to the bottom of the equipment base plate 1, and the exhaust fan 3 is fixed to the top of the equipment base plate 1. The electric wheels 17 can be adjusted to the working position without manual pushing.

[0037] The cleaning assembly 7 includes a cleaning rod 701, which is rotatably mounted inside the wall dust cover 6. A cleaning motor 702 is fixedly connected to one end of the cleaning rod 701. The cleaning motor 702 is positioned on the outer surface of the wall dust cover 6. After the cleaning motor 702 is started, it drives the cleaning rod 701 inside the wall dust cover 6 to rotate. The cleaning rod 701 mechanically peels off the dust accumulated on the wall or ceiling by rotating, loosening the stubborn dust. This active cleaning, combined with the negative pressure adsorption of the exhaust fan 3, can effectively solve the problem of sticky dust that is difficult to remove by simple vacuuming, and improve the cleanliness of dust removal.

[0038] The clamping assembly 9 includes a base 901, which is fixedly connected to one end of the electric telescopic rod 8. A strip-shaped groove is provided on the top of the base 901, and a bidirectional lead screw 902 is rotatably installed in the strip-shaped groove. A drive motor 903 is fixedly installed on the outer wall of the base 901, and one end of the drive motor 903 is fixed to the bidirectional lead screw 902. The bidirectional lead screw 902 is symmetrically threaded to a drive block 904. A clamping seat 905 is fixedly installed on the top of the drive block 904. A transverse arc-shaped groove 906 and a vertical arc-shaped groove 907 are respectively provided on the clamping seat 905, and the clamping tube 5 is located in the transverse arc-shaped groove 906.

[0039] After the drive motor 903 is started, it drives the bidirectional lead screw 902 to rotate, which in turn drives the two drive blocks 904 to move relative to each other along the strip groove. This causes the clamping seat 905 to move closer to the clamping tube 5 and clamp it in place. When the clamping tube 5 is embedded in the horizontal arc groove 906, it can achieve horizontal positioning, which is suitable for wall dust removal operations. When switching to the vertical arc groove 907 for clamping, it can quickly complete vertical positioning, which meets the needs of wall top dust removal.

[0040] The positioning component 16 includes a vertical plate 1601. A limiting groove is formed on one side of the vertical plate 1601. A linkage block 1602 is slidably engaged in the limiting groove. An arc-shaped positioning seat 1603 is fixed on one end of the linkage block 1602. The arc-shaped positioning seat 1603 is located above the positioning flange 15. A miniature cylinder 1604 is fixed on the top of the vertical plate 1601. One end of the miniature cylinder 1604 is connected to the linkage block 1602. An external thread is formed on the outer wall of the connecting sleeve 13.

[0041] Activating the micro cylinder 1604 pushes the linkage block 1602 to slide downward along the limiting groove of the vertical plate 1601, causing the arc-shaped positioning seat 1603 to move downward synchronously until the arc-shaped positioning seat 1603 fits and locks against the positioning flange 15 of the connecting sleeve 13, thus achieving a stable connection between the second dust guide tube 12 and the ground dust cover 10. This prevents the connecting sleeve 13 from loosening or leaking air when the equipment moves or when vacuuming under negative pressure, ensuring stable suction for ground dust removal. When maintenance or switching the vacuuming mode is required, controlling the micro cylinder 1604 to retract causes the linkage block 1602 to move the arc-shaped positioning seat 1603 upward and disengage from the positioning flange 15, allowing the connecting sleeve 13 to be removed. At this time, the connecting sleeve 13 can be connected to other types of vacuum heads, such as narrow slot vacuum heads and brush vacuum heads, through external threads, flexibly adapting to dust removal in special areas such as corners and equipment gaps in warehouses, expanding the equipment's application scenarios.

[0042] Both the first dust guide pipe 4 and the second dust guide pipe 12 are connected to valves 18 at the ends near the dust collection box 2. When cleaning the wall or the top of the wall, the corresponding valves 18 are turned off or opened.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
