Description

Technical Field

[0001] This utility model relates to the field of agricultural engineering machinery technology, specifically to a durable and long-lasting generator. Background Technology

[0002] Agricultural machinery often operates in harsh environments with high dust levels, abundant weeds, and crop debris, causing debris to easily accumulate at the cooling vents at the rear of the generator. The traditional solution is to replace the large orifices with smaller ones, which, while preventing larger particles from entering, makes the smaller holes more prone to clogging, resulting in insufficient airflow and poor generator heat dissipation, thus affecting its power generation performance and reliability. Simultaneously, some fine debris still enters the generator with the airflow and is difficult to clean; severe accumulation can lead to a sudden rise in internal temperature due to poor heat dissipation, even causing a fire, posing a significant safety hazard. Furthermore, continuous dust intrusion accelerates generator aging and shortens its lifespan.

[0003] Chinese Patent Publication No. CN213243699U discloses an agricultural machinery generator. When the generator is operating, cooling air enters through the air inlet of the end cover and is first filtered by an air filtration mechanism. The air filtration mechanism includes a supporting frame and a filter assembly: the cover plate of the supporting frame overlaps with the end cover, and the bearing member forms a ring structure with the cover plate; the filter assembly consists of a first filter screen and a second filter screen, which are installed parallel and spaced apart within the supporting frame. The first filter screen has a larger pore size to block large particles of debris; the second filter screen has a smaller pore size to further filter fine debris. The filtered clean air enters the generator body opening for heat dissipation. Some of the blocked debris adheres to the filter screen, while the remaining particles fall into the dust discharge valve along the guide channel at the bottom of the end cover under gravity and are periodically discharged through the dust discharge valve. A temperature sensor is installed on the generator body to monitor the internal temperature in real time; if the temperature rises abnormally, an alarm is triggered by the ECU, prompting the cleaning of blockages or troubleshooting. However, in this device, the impurities on the filter screen fall down due to their own gravity and are then collected. But impurities generally have a high degree of adhesion, and it is not easy to separate them from the filter screen by their own gravity alone.

[0004] Therefore, this application aims to provide a durable and long-lasting generator to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned issues, a durable and long-lasting generator is provided. This generator features a first and second filter screen arranged parallel to each other within the mounting socket of the impurity filtration mechanism. A rotatable first cleaning brush is mounted on the first filter screen, and a rotatable second cleaning brush is mounted on the second filter screen. The brush bristles, in contact with the corresponding filter screen, scrape away adhering impurities during rotation, solving the clogging problem caused by the strong adhesion of impurities in traditional filters, which is difficult to effectively separate using gravity alone. Furthermore, the plug-in design of the mounting slot and socket allows for quick disassembly of the impurity filtration mechanism, facilitating cleaning or replacement of the filter screens and cleaning brush assemblies, ensuring efficient airflow and long-term stable operation of the generator.

[0006] To address the problems of existing technologies, this utility model provides a durable and long-lasting generator, including a generator body. One end of the generator body has an opening, and an end cover is installed at the opening. The end cover has an air inlet for air circulation, and a mounting slot is provided on the side of the end cover. An impurity filter mechanism is inserted into the mounting slot. The impurity filter mechanism includes a mounting socket adapted to the mounting slot. A first filter screen and a second filter screen are arranged parallel to each other in the mounting socket. A first cleaning brush is rotatably mounted on the first filter screen, and a second cleaning brush is rotatably mounted on the second filter screen. The bristles of the first cleaning brush abut against the first filter screen, and the bristles of the second cleaning brush abut against the second filter screen.

[0007] Preferably, the bottom end of the end cap is provided with a dust discharge port for discharging debris, and a dust collection box is installed at the dust discharge port for collecting the impurities discharged from the discharge port.

[0008] Preferably, the mesh size of the first filter screen is larger than that of the second filter screen.

[0009] Preferably, the generator body has an opening with a mounting base, the mounting base has a threaded hole, and the end cap has a through hole at the end near the opening of the generator body corresponding to the position of the threaded hole. When the end cap is installed at the opening of the generator body, the threaded hole and the through hole are aligned, and the same bolt is threaded into the threaded hole and the through hole.

[0010] Preferably, the end cap has a limiting block around the through hole that is adapted to the mounting base, so that when the end cap is installed at the generator opening, the mounting base is placed inside the limiting block.

[0011] Preferably, a first toothed disc is fixedly connected to the edge of the first cleaning brush, and a second toothed disc is fixedly connected to the edge of the second cleaning brush. The top of the end cap has a through hole adapted to the first and second toothed discs. The first toothed disc is meshed with a first gear, and the second toothed disc is meshed with a second gear.

[0012] Preferably, the first gear and the second gear are connected to the same rotating shaft, and the first gear and the second gear are provided with a protective housing, with one end of the rotating shaft extending out of the protective housing.

[0013] Preferably, the end of the rotating shaft that extends out of the protective housing is provided with an auxiliary handle that is easy for the operator to hold.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This utility model provides a rotatable cleaning brush on the first and second filter screens. By utilizing the continuous contact between the brush bristles and the filter screens, it effectively removes adhesive impurities, solving the problem of low self-cleaning efficiency of traditional filter screens that rely on gravity. This significantly improves the filter screens' anti-clogging ability and ensures airflow efficiency and generator heat dissipation stability.

[0016] 2. This utility model adopts a graded filtration design. By combining a first filter and a second filter with different mesh sizes, and with the integrated structure of the dust discharge port and the dust collection box, it can achieve layered interception, automatic cleaning and centralized collection of impurities, reduce the frequency of manual cleaning, avoid secondary pollution by impurities, and ensure the long-term operation of the generator.

[0017] 3. This utility model achieves rapid disassembly and assembly, precise alignment, and convenient operation of the end cap and filter assembly through the plug-in design of the mounting slot and impurity filtration mechanism, the coordinated positioning structure of the bolt and the limiting block, and the linkage drive system of gear transmission and auxiliary handle, which significantly improves maintenance efficiency and reduces operation and maintenance costs.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 As shown: A durable and long-lasting generator includes a generator body 1. One end of the generator body 1 has an opening, and an end cover 2 is installed at the opening. The end cover 2 has an air inlet for air circulation. A mounting slot 3 is provided on the side of the end cover 2. An impurity filter mechanism 4 is inserted into the mounting slot 3. The impurity filter mechanism 4 includes a mounting socket 5 adapted to the mounting slot 3. A first filter screen 6 and a second filter screen 7 are arranged parallel to each other in the mounting socket 5. A first cleaning brush 8 is rotatably mounted on the first filter screen 6, and a second cleaning brush 9 is rotatably mounted on the second filter screen 7. The bristles of the first cleaning brush 8 abut against the first filter screen 6, and the bristles of the second cleaning brush 9 abut against the second filter screen 7.

[0027] In existing technologies, impurities on the filter screen fall and are collected due to their own gravity. However, impurities generally have strong adhesion and are not easily separated from the filter screen by their own gravity alone. To solve this problem, in this application, external cooling air enters the opening of the generator body 1 through the air inlet on the end cover 2. An impurity filter mechanism 4 is inserted into the mounting slot 3 on the side of the end cover 2. The mounting socket 5 of the impurity filter mechanism 4 is fitted and fixed to the mounting slot 3. A first filter screen 6 and a second filter screen 7 are arranged parallel to each other inside the mounting socket 5. When air flows through the first filter screen 6, larger particles of impurities are blocked; the remaining air continues to pass through the second filter screen 7, further filtering out fine debris. A first cleaning brush 8, which is rotatably mounted on the surface of the first filter screen 6, scrapes off the impurities attached to the first filter screen 6 during rotation by the abutting action of the bristles against the first filter screen 6; a second cleaning brush 9, which is rotatably mounted on the surface of the second filter screen 7, removes the accumulated dust on the surface of the second filter screen 7 in the same way. The continuous rotation of the first cleaning brush 8 and the second cleaning brush 9 can prevent impurities from accumulating and clogging the filter screen, maintaining airflow efficiency. The filtered clean air enters the generator body 1 for heat dissipation, ensuring the long-term stable operation of the generator body 1. The impurity filter mechanism 4 can be quickly disassembled through the plug-in design of the mounting socket 5 and the mounting slot 3, which facilitates the cleaning or replacement of the filter screen and cleaning brush assembly.

[0028] Reference Figures 1-4 As shown: The bottom end of the end cap 2 is provided with a dust discharge port 10 for discharging debris, and a dust collection box 11 for collecting the impurities discharged from the discharge port is installed at the dust discharge port 10.

[0029] The dust discharge port 10 at the bottom of the end cover 2 serves as a discharge channel for impurities. Impurities removed during filtration fall naturally to the bottom of the end cover 2 under gravity. The dust discharge port 10 is connected to the interior of the end cover 2, allowing impurities accumulated at the bottom to be discharged outwards through the dust discharge port 10. A dust collection box 11, installed at the dust discharge port 10, is fixed by a snap-fit ​​or threaded connection and is used to receive and store impurities discharged from the dust discharge port 10. The opening of the dust collection box 11 is aligned with the dust discharge port 10, ensuring that impurities fall directly into the dust collection box 11 and preventing them from scattering into the external environment. The dust collection box 11 is detachable; when impurities accumulate to a certain amount, it can be manually disassembled for cleaning or replacement. The sealing structure of the dust collection box 11 prevents leakage of impurities during collection without affecting the normal dust discharge function of the dust discharge port 10. Through the cooperation of the dust discharge port 10 and the dust collection box 11, efficient collection and centralized processing of impurities are achieved, reducing the frequency of manual cleaning and ensuring the continuous and stable operation of the generator body 1.

[0030] Reference Figure 6 As shown: the mesh size of the first filter screen 6 is larger than that of the second filter screen 7.

[0031] As external cooling air flows sequentially through the first filter 6 and the second filter 7, the larger openings of the first filter 6 initially intercept larger particulate impurities in the air, reducing the initial filtration load. The remaining air containing fine debris continues to flow to the second filter 7, where the smaller openings further block even finer dust and debris, creating a multi-stage filtration effect. The difference in mesh size between the first filter 6 and the second filter 7 prevents large particles from directly impacting the second filter 7, reducing the risk of clogging and extending its service life. The parallel and spaced arrangement of the two-stage filters ensures stable airflow during both filtration processes, guaranteeing that the filtered air cleanliness meets the heat dissipation requirements of the generator body 1. The synergistic effect of the first filter 6 and the second filter 7 ensures filtration efficiency while reducing frequent clogging caused by excessively small pore sizes in a single filter, improving the overall filtration system's longevity and ease of maintenance.

[0032] Reference Figures 1-4 As shown: The generator body 1 has an opening with a mounting base 12, and the mounting base 12 has a threaded hole. The end cover 2 has a through hole at the end near the opening of the generator body 1, corresponding to the position of the threaded hole. When the end cover 2 is installed at the opening of the generator body 1, the threaded hole and the through hole are aligned. At this time, the same bolt is threadedly connected to the threaded hole and the through hole.

[0033] The mounting base 12 is fixed to the edge of the opening of the generator body 1. When the end cover 2 is installed at the opening, the through hole and the threaded hole completely overlap to form a continuous channel. At this time, the same bolt passes through the through hole of the end cover 2 and is screwed into the threaded hole of the mounting base 12 in sequence. The threaded connection of the bolt tightly fixes the end cover 2 and the mounting base 12. The tightening force of the bolt creates a rigid connection between the end cover 2 and the mounting base 12, ensuring that the end cover 2 remains stable when subjected to airflow pressure or vibration during generator operation.

[0034] Reference Figures 1-4 As shown: The end cover 2 has a limiting block 13 around the through hole that is adapted to the mounting base 12. When the end cover 2 is installed at the generator opening, the mounting base 12 is placed inside the limiting block 13.

[0035] The limiting block 13 around the through hole of the end cover 2 matches the contour shape of the mounting base 12. When the end cover 2 is installed at the opening of the generator body 1, the mounting base 12 is completely embedded in the space formed by the limiting block 13. The physical constraint of the limiting block 13 prevents the mounting base 12 from shifting laterally during installation, ensuring that the threaded hole on the mounting base 12 and the through hole of the end cover 2 always remain coaxially aligned.

[0036] Reference Figure 5As shown: a first toothed disc 14 is fixedly connected to the edge of the first cleaning brush 8, and a second toothed disc 15 is fixedly connected to the edge of the second cleaning brush 9. The top of the end cap 2 has a through hole that matches the first toothed disc 14 and the second toothed disc 15. The first toothed disc 14 is meshed with a first gear 16, and the second toothed disc 15 is meshed with a second gear 17.

[0037] As external cooling air flows through the first filter 6 and the second filter 7, the first toothed disc 14, fixedly connected to the edge of the first cleaning brush 8, and the second toothed disc 15, fixedly connected to the edge of the second cleaning brush 9, are respectively embedded in the through holes opened at the top of the end cover 2. The first toothed disc 14 is connected to the first gear 16 outside the end cover 2 through tooth meshing, and the second toothed disc 15 meshes with the second gear 17 in the same way, forming a transmission relationship. When the external drive device drives the first gear 16 and the second gear 17 to rotate, the first gear 16 drives the first toothed disc 14 to rotate through meshing, and the second gear 17 synchronously drives the second toothed disc 15 to rotate. The rotation of the first toothed disc 14 causes the first cleaning brush 8 to rotate around its own axis, and the rotation of the second toothed disc 15 causes the second cleaning brush 9 to rotate synchronously. During the rotation, the bristles of the first cleaning brush 8 continuously scrape the surface of the first filter 6 to remove attached large particles of impurities; the bristles of the second cleaning brush 9 clean the surface of the second filter 7 in the same way, removing accumulated fine debris.

[0038] Reference Figures 1-6 As shown: the first gear 16 and the second gear 17 are connected to the same rotating shaft. The first gear 16 and the second gear 17 are provided with protective housings, and one end of the rotating shaft passes through the protective housing.

[0039] The protective housing encloses the meshing parts of the first gear 16, the second gear 17, and the rotating shaft, preventing dust, moisture, or foreign objects from entering the gear transmission area, while also reducing the evaporation or contamination of lubricating grease. The rotation of the rotating shaft drives the first gear 16 and the second gear 17 to rotate at the same angular velocity. The first gear 16 drives the first gear disc 14 and the first cleaning brush 8 to rotate around the shaft through tooth meshing, while the second gear 17 synchronously drives the second gear disc 15 and the second cleaning brush 9 to rotate.

[0040] Reference Figures 1-5 As shown: The end of the rotating shaft that extends out of the protective housing is provided with an auxiliary handle that is easy for the operator to hold.

[0041] An auxiliary handle at one end of the rotating shaft extending out of the protective housing provides a gripping point for the operator. The operator manually rotates the auxiliary handle to drive the rotating shaft to rotate synchronously. The rotation of the auxiliary handle is transmitted to the rotating shaft, causing the first gear 16 and the second gear 17 to rotate the first gear disc 14 and the second gear disc 15 at the same angular velocity. The meshing transmission between the first gear disc 14 and the first gear 16 causes the first cleaning brush 8 to rotate around the shaft, and the meshing action between the second gear disc 15 and the second gear 17 drives the second cleaning brush 9 to rotate synchronously. During rotation, the bristles of the first cleaning brush 8 and the second cleaning brush 9 continuously scrape the surfaces of the first filter screen 6 and the second filter screen 7, removing attached impurities and preventing the filter screens from clogging. To prevent impurities from passing through the first filter screen 6 and the second filter screen 7 and being sucked into the generator body 1 during cleaning, the generator can be stopped before cleaning the first filter screen 6 and the second filter screen 7.

[0042] Working Principle: The working principle of this durable and long-lasting generator is as follows: External cooling air enters the generator body 1 through the air inlet of the end cover 2, and flows sequentially through the first filter screen 6 and the second filter screen 7 of the impurity filtration mechanism 4. The first filter screen 6 has larger mesh openings to intercept large particles of impurities, while the second filter screen 7 has smaller mesh openings to filter fine debris. The first cleaning brush 8 and the second cleaning brush 9 respectively scrape off the attached impurities by contacting the surface of the corresponding filter screen with their bristles during rotation. The cleaning brushes are driven by the first gear 14 and the second gear 15 on the top of the end cover 2. The gears mesh with the external first gear 16 and the second gear 17, and the gears are linked through the same rotating shaft. An auxiliary handle is provided at the end of the rotating shaft for manual rotation. The scraped-off impurities fall into the dust collection box 11 through the dust discharge port 10 at the bottom of the end cover 2. The end cover 2 is fixed to the mounting base 12 at the opening of the generator body 1 by bolts, and the limiting block 13 ensures the installation alignment accuracy. The filtered clean air enters the generator for heat dissipation, maintaining its long-term stable operation.

Therefore, the protection scope of this utility model should be determined by the appended claims.
