Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of supporting equipment for grain storage in warehouses, specifically an auxiliary tool for efficiently cleaning residual grain impurities inside the double-layered troughs on the inner wall of a warehouse before the warehouse is covered with film. Background Technology
[0002] In the grain storage process in warehouses, the double-layered sealing troughs are a key structural element of the warehouse walls. Their core function is to provide a sealed foundation for subsequent film covering. The film must tightly cover the inner walls of both layers of the sealing troughs to achieve moisture-proof and oxygen-barrier sealing, preventing the grain from becoming damp and moldy. However, before film covering, grain particles, debris, and other impurities may remain inside the two layers of the sealing troughs. If these impurities are not thoroughly removed, gaps will appear between the film and the inner walls of the troughs, compromising the sealing effect and ultimately leading to grain storage quality problems.
[0003] Current cleaning methods for double-layered pits have three major drawbacks:
[0004] Manual cleaning is inefficient and incomplete: Traditional manual cleaning using tools such as brushes and scrapers is difficult because the width of the double-layer pit 7 is narrow (usually only 20-30mm) and the depth is shallow (15-20mm). Manual tools cannot reach the bottom and corners of the pit, which easily creates cleaning dead corners. The residual rate of impurities exceeds 40%, and cleaning a single meter of pit takes more than 1 minute, which is extremely inefficient.
[0005] Poor compatibility of ordinary air blowers: In some scenarios, we tried to use portable air blowers 2 to blow directly, but ordinary air blowers have a single air outlet and cannot match the "two-layer pit" structure of the double-layer pit 7. They can only clean one layer at a time, and the airflow from the outlet is dispersed, which easily blows impurities from the upper pit to the lower pit, resulting in "impurity transfer" rather than "impurity removal", and the cleaning effect is ineffective.
[0006] Portability versus functionality: There is no fixed air source in the warehouse, and cleaning equipment needs to rely on portable power (such as rechargeable hair dryers). However, existing cleaning tools either focus only on "portability" (such as small brushes) but lack efficient cleaning capabilities, or focus on "cleaning power" (such as high-power hair dryers) but lack a structure adapted to the double-layer groove, and cannot meet the three core requirements of "no fixed air source adaptation", "double-layer synchronous cleaning" and "concentrated air volume".
[0007] Therefore, there is an urgent need for a cleaning auxiliary tool that can adapt to warehouses without a fixed air source, precisely match the structure of the double-layered pit trough, and efficiently remove impurities, thus solving the pain points of existing cleaning methods. Utility Model Content
[0008] This utility model aims to solve the problems of "incomplete manual cleaning, poor compatibility with ordinary air ducts, and inability to balance portability and functionality" in the existing double-layer pit cleaning of warehouses, and to achieve the goal of "adapting to portable air ducts, simultaneous cleaning of double layers, and concentrated and efficient removal of impurities".
[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0010] A cleaning aid for double-layer forcing troughs, characterized in that it is used to clean grain impurities inside the double-layer forcing troughs before covering the warehouse with film, the cleaning aid comprising:
[0011] The connecting part is used to detachably connect with a portable air duct to adapt to the usage scenario of warehouses without a fixed air source;
[0012] The double-layer air outlet structure is connected to the connecting part, and the two air outlets of the double-layer air outlet structure correspond one-to-one with the two layers of the double-layer forcing trough. The double-layer air outlet structure is used to gather the air volume output by the portable air blower to efficiently remove grain impurities inside the double-layer forcing trough.
[0013] Furthermore, the connecting part is a snap-fit connection structure, a threaded connection structure, or a plug-in connection structure to achieve quick installation and disassembly with the portable air blower.
[0014] Furthermore, the cross-sectional shape of each air outlet of the double-layer air outlet structure is circular, rectangular, polygonal, or an irregular structure adapted to the contour of the double-layer groove, and the size of each air outlet is adapted to the width and depth of the corresponding groove.
[0015] Furthermore, the double-layer air outlet structure and the connecting part are integrally formed, and a guide part is integrally formed between the double-layer air outlet structure and the connecting part. The guide part is a gradually narrowing conical structure. The large end of the guide part is connected to the connecting part, and the small end is connected to the double-layer air outlet structure, so as to guide the converged airflow to be output from the double-layer air outlet structure.
[0016] Furthermore, the double-layer air outlet structure and the connecting part are separate structures, and the two are assembled and fixed by means of threads, snaps or adhesives, so as to facilitate the replacement of the air outlet component or the connecting part component separately.
[0017] An integral guide section is formed between the double-layer air outlet structure and the connecting part. The guide section is a gradually narrowing conical structure. The large end of the guide section is connected to the connecting part, and the small end is connected to the double-layer air outlet structure to guide the converged airflow to be output from the double-layer air outlet structure.
[0018] Furthermore, a gradually contracting micro-guide structure is formed within the double-layer air outlet structure, and the micro-guide structure is connected to the guide section.
[0019] Furthermore, the main body of the cleaning aid is made of a lightweight and wear-resistant material, which is selected from plastics, aluminum alloys, magnesium alloys, or engineering resins.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This utility model proposes a double-layer pit cleaning auxiliary tool, comprising a connecting part for detachable connection with a portable air blower to adapt to scenarios where there is no fixed air source in the warehouse, and a double-layer air outlet structure connected to the connecting part with two air outlets corresponding to the two layers of pits in the double-layer pit.

The two can be assembled in one piece or separately. The main body of the tool is made of lightweight and wear-resistant material.

[0031] like Figure 1-3 As shown, this utility model provides a double-layer pit cleaning auxiliary tool. The core structure includes a connecting part 1 and a double-layer air outlet structure 3. The specific design and connection relationship of each structure are as follows:
[0032] 1. Core Component Design
[0033] Connecting part 1
[0034] Function: It can be detachably connected to the portable air blower 2, and is suitable for use in warehouses where there is no fixed air source.
[0035] Structural options: Optional snap-fit connection, threaded connection, or plug-in connection.
[0036] Clip-on connection: The inner wall of the connecting part 1 is provided with several evenly distributed elastic clips, which are adapted to the annular groove of the air outlet of the portable air blower 2. Pressing the clips will lock them in place, and gently prying the clips will separate them. The installation / disassembly time is ≤5 seconds.
[0037] Threaded connection: The inner wall of the connecting part 1 is provided with an internal thread, which matches the external thread of the air outlet of the portable air blower 2. It can be locked by rotating 2-3 turns, and there is no air leakage.
[0038] Plug-in connection: The connector 1 is made of elastic silicone material, and its inner diameter is interference-fitted with the outer diameter of the air outlet of the portable air blower 2. It can be fixed by inserting and separated by pulling it out, and is compatible with various air blower diameters.
[0039] Double-layer air outlet structure 3
[0040] Function: Connects to the connecting part 1, and through two air outlets corresponding one-to-one with the two layers of grooves of the double-layer groove 7, gathers the air volume output by the portable air blower 2 to achieve double-layer synchronous cleaning.
[0041] Structural details:
[0042] Air outlet shape: The cross-section can be circular, rectangular, polygonal or irregular structure that fits the inner wall contour of the double-layer pit 7 (such as U-shaped that fits the inner wall of the pit), ensuring that the gap between the air outlet and the inner wall of the pit is ≤2mm, reducing air leakage;
[0043] Air outlet dimensions: The width is consistent with the width of the corresponding floor recess.
[0044] 2. Flow guiding and assembly structure design
[0045] Flow guide 4
[0046] Location: The guide part 4 is integrally formed between the connecting part 1 and the double-layer air outlet structure 3. Whether the two are integrally formed or separate structures, the guide part 4 is provided.
[0047] Structure: It is a gradually tapering cone structure. The large end connects to the connecting part 1 (the diameter is the same as the air outlet diameter of the connecting part 1), and the small end connects to the double-layer air outlet structure 3 (the diameter is the total air inlet diameter of the double-layer air outlet structure 3). This can improve the efficiency of airflow convergence and prevent airflow from diffusing between the connecting part 1 and the air outlet.
[0048] Miniature flow guiding structure 5
[0049] Location: Located inside the double-layer air outlet structure 3, and connected to the air guide section 4.
[0050] Structure: It is a gradually contracting structure. The diameter of the air inlet is the same as the diameter of the small end of the guide section 4, and the diameter of the air outlet is the same as the diameter of the air outlet. This can further contract and accelerate the airflow, increase the air outlet wind speed, and enhance the impurity removal force.
[0051] Assembly method
[0052] There are two types to suit different usage needs:
[0053] One-piece molding structure: The connecting part 1, the air guide part 4, and the double-layer air outlet structure 3 are all made of the same material by injection molding or die casting. The structure is stable with no assembly gaps and no air leakage, making it suitable for long-term fixed use.
[0054] Split structure: The connecting part 1 and the double-layer air outlet structure 3 are independent components, which are assembled and fixed by means of threads, snaps or adhesives. The worn connecting part 1 or air outlet components can be replaced separately, reducing maintenance costs.
[0055] 3. Material Selection
[0056] The main body of the cleaning aid tool is made of lightweight and wear-resistant material; specific options are available:
[0057] Plastics: Low cost, lightweight, suitable for mass production;
[0058] Aluminum alloy: High strength and wear resistance, suitable for frequent use scenarios;
[0059] Magnesium alloy: Lighter in weight and stronger than plastic, making it suitable for prolonged handheld operation;
[0060] Engineering resins: combine impact resistance and corrosion resistance, making them suitable for humid warehouse environments.
[0061] This double-layer sump cleaning aid effectively solves the problems of inefficient and incomplete manual cleaning of double-layer sump cleaning in warehouses, poor compatibility of ordinary air ducts, and the inability to balance portability and functionality. It can adapt to warehouse scenarios without a fixed air source, achieving simultaneous cleaning of double-layer sump cleaning. The airflow is concentrated through the guide section and micro-guide structure to ensure thorough removal of impurities. It can be adapted to double-layer sump cleaning of different specifications. The one-piece molded structure is stable and has no airflow leakage. The split structure makes it easy to replace parts individually, reducing maintenance costs. The use of lightweight and wear-resistant materials makes the tool easy to operate and has no safety hazards during use.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
