Description

Technical Field

[0001] This utility model relates to the field of impurity cleaning devices, specifically a backpack-type device for removing impurities and pests from grain warehouses. Background Technology

[0002] In the grain storage sector, during the storage and handling of grains such as rice and wheat, dust, husks, and straw naturally accumulate on work surfaces, ventilation ducts, and grain surfaces due to the grains themselves carrying impurities. These impurities severely impact the air and working environment within the storage facility and create favorable conditions for the growth and reproduction of pests. Furthermore, dozens of common pest species are found in grain storage facilities, some of which, such as wheat moths and booklice, multiply rapidly and crawl or fly towards the walls when temperature and humidity are suitable. These pests are small, numerous, highly mobile, and have high moisture content, often congregating on the grain surface and walls, seriously threatening the safety of stored grain.

[0003] Currently, the common method for controlling booklice and other pests is whole-warehouse chemical fumigation. While effective, this method has serious subsequent problems. First, fumigation agents remain in the grain, requiring a long time to decompose. Second, the pesticide odor is very strong on the grain. Third, fumigation is a specialized operation requiring professional personnel with specialized equipment, posing a certain degree of danger. Fourth, fumigation agents are expensive, making it uneconomical. Fifth, a large number of dead booklice and other pests fall from the walls and accumulate at the boundary between the walls and the grain surface, causing a sharp increase in grain moisture, leading to mold and residue buildup. Sixth, the chemical agents themselves pose significant risks to human health and grain quality, failing to meet the industry's requirements for green and scientific grain storage. Furthermore, some workers use brooms to directly sweep the walls to remove booklice. This method only provides temporary cleaning; many booklice fall into the grain during the sweeping process and quickly re-aggregate on the walls, failing to fundamentally solve the problem of booklice threatening grain storage safety. Utility Model Content

[0004] Therefore, to address the aforementioned shortcomings, this utility model provides a backpack-type impurity and pest removal device for grain storage. This device, through the installation of an adsorption cylinder and an adsorption head held in a flexible connection by a connecting component, combined with a fan blade inside the adsorption cylinder driven by a motor, creates negative pressure, facilitating the adsorption head to approach the wall or grain surface to remove impurities. This allows booklice on the wall and dust, rice husks, straw, etc., on the grain surface to be adsorbed into the adsorption cylinder. A movable filter component inside the adsorption cylinder filters out impurities, preventing them from being directly discharged from the air outlet. This filter component can be fixed by the closing of the cover, and can also be removed when the cover is opened for easy cleaning. Therefore, this device effectively adsorbs and centrally collects impurities from the wall or grain surface for cleaning.

[0005] This utility model is implemented by constructing a backpack-type grain storage device for removing impurities and pests, including an adsorption cylinder with a cover movably installed on the top.

[0006] The adsorption head is connected to the cover via a connecting component and communicates with the inside of the adsorption cylinder.

[0007] The filter assembly is movably placed inside the adsorption cylinder and fixed by the cover;

[0008] The motor housing is located at the bottom of the adsorption cylinder and contains a drive motor.

[0009] Rotating fan blades are provided at the bottom of the adsorption cylinder, and the fan blades are connected to the drive shaft of the drive motor. An exhaust port is provided at the side end of the adsorption cylinder.

[0010] Preferably, the connecting assembly includes a connecting hose and an adsorption rod. One end of the connecting hose is rotatably connected to the center of the cover, and the other end is connected to the adsorption rod. An adsorption head is movably connected to the end of the adsorption rod.

[0011] Preferably, the adsorption cylinder is provided with a carrying strap on the outside.

[0012] Preferably, a waist belt is also provided at the outer end of the shoulder strap. The waist belt is connected or disconnected by a buckle. A power bank is placed on the waist belt via a hanging bag. The power bank supplies power to the drive motor. The power bank is also provided with a switch, a power adjustment knob, and a charging port.

[0013] Preferably, the filter assembly includes a support frame and a filter cloth sleeved on the outer end of the support frame. The support frame has a conical structure that is larger at the top and smaller at the bottom, and has a large ring and a small ring that is connected by several circumferentially distributed connecting rods. The support frame is supported on the top edge of the adsorption cylinder by the large ring and is pressed together with the cover. The filter cloth is sleeved on the outside of the small ring and connecting rod of the support frame and fixed on the large ring. A handle is also provided at the inner end of the large ring of the support frame.

[0014] Preferably, the shape of the adsorption head is round, braided, circular, or rectangular.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] First, this suction device uses an adsorption cylinder, an adsorption head, and a fan blade driven by a motor to create a negative pressure structure, which can accurately and efficiently adsorb booklice on the wall and impurities such as dust, rice husks, and straw on the grain surface. Compared with traditional manual cleaning methods, it greatly improves cleaning efficiency and avoids the problem of booklice falling back into the grain and causing secondary accumulation, thus effectively ensuring the safety of stored grain.

[0017] Secondly, the device completely eliminates the use of chemical pesticides and treats impurities through physical adsorption, avoiding the harm of chemical pollution to human health and grain quality. It meets the industry development requirements of green and scientific grain storage and provides a strong guarantee for the safe storage and green quality of grain.

[0018] Finally, the device features a movable filter assembly inside the adsorption cylinder, effectively separating impurities from the gas and preventing secondary pollution caused by impurities escaping from the outlet. Furthermore, the filter assembly is linked to the cover, allowing for easy removal and cleaning by simply opening the cover. Compared to existing equipment with filtration functions that are difficult to disassemble, this significantly reduces maintenance complexity, meets the long-term, high-frequency cleaning needs of grain storage, and substantially improves convenience and practicality.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of this utility model and are not intended to limit this utility model in any way. The accompanying drawings in this utility model are only for illustrative purposes and to facilitate understanding of the embodiments and are not intended to limit this utility model in any way.

[0026] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented.

[0027] As described in the background section, impurities often accumulate on the grain surface or walls when grain is stored in a grain silo. Existing methods for handling these impurities include:

[0028] To address impurities: One approach is to manually pick them up; another is to lightly sweep them with a broom. Both methods are inefficient, labor-intensive, and carry the risk of falling into grain pits while working on the grain surface.

[0029] For booklice and other pests: First, whole-warehouse fumigation is the most effective method for eradicating them, but it is expensive and involves complicated approval and procedures. Second, lowering the grain temperature causes booklice to retreat to warmer areas within the grain, creating an abnormally high grain temperature even if the surface is free of pests. Third, spraying with chemical agents such as deltamethrin is effective, but deltamethrin is a toxic and harmful pesticide; contaminating the grain would cause serious food safety problems and does not meet the requirements of green and technologically advanced grain storage.

[0030] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:

[0031] Example 1,

[0032] Please see the appendix Figure 1 ~Appendix Figure 4 A backpack-type device for removing impurities and pests in grain warehouses includes an adsorption cylinder 1 and a cover 2 movably installed on the top.

It can also be quickly placed in the adsorption cylinder and fixed by the cover. The handle makes it easy to take it out and empty the filtered impurities.

[0048] Furthermore, the cover and the adsorption cylinder can be connected by a snap-fit ​​or a threaded connection (the attached figure shows a threaded connection). The filter assembly can also be set as other conventional mesh structures, such as a ring and a filter cloth connected to the ring.
