Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and in particular to a dust removal device and method for preventing clogging in the heat dissipation system of engineering machinery. Background Technology

[0002] Radiators for construction machinery are crucial cooling devices that ensure the normal operation of core components. They effectively dissipate excess heat generated during operation, preventing problems such as power loss and component damage due to overheating. They are widely used in various types of construction machinery, including excavators, loaders, and cranes. Taking the most common forced-air-cooled radiator as an example, high-temperature coolant or hydraulic oil flows from the engine or hydraulic system into the metal pipes of the radiator core. Heat is transferred through the pipe walls to the external heat sink fins. At this time, the fan operates, generating forced airflow that quickly flows over the surface of the heat sink fins, carrying away the heat and lowering the temperature of the medium inside the pipes. The cooled medium then flows back to the engine or hydraulic system through the return port, thus completing the cycle and achieving continuous cooling.

[0003] Cooling systems typically require filters at the air inlet to prevent dust from entering the machinery. However, clogged filters can impede ventilation and heat dissipation, necessitating regular dust removal. Existing dust removal devices are not compatible with different air inlets, lacking versatility, and cannot effectively collect and process the cleaned dust, potentially causing secondary pollution. Improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of poor assembly flexibility and low versatility of existing dust removal devices, and to provide a dust removal device and method for preventing clogging in the heat dissipation system of engineering machinery. This improves the ease of assembly, ensures smooth ventilation at the air inlet, and avoids a decrease in heat dissipation efficiency due to filter clogging. At the same time, it provides a dust removal device with a dust collection function, which centrally collects the cleaned dust, prevents secondary dust dispersion, reduces wear and contamination of heat dissipation components, lowers maintenance frequency, and extends the service life of the radiator of engineering machinery.

[0005] According to one objective of the present invention, the present invention provides a dust removal and anti-clogging device for a heat dissipation system of engineering machinery, including a snap-fit ​​mesh cover, wherein a shaft column is rotatably mounted at the center of the inner side of the snap-fit ​​mesh cover via a rotating shaft, and an abutment plate is fixedly connected to the inner side of the snap-fit ​​mesh cover and located outside the shaft column, wherein a plurality of arc-shaped openings are provided on the outer side of the abutment plate. A screw is threaded into the internal thread of the shaft. A sleeve is rotatably mounted on the outer wall of the screw and located outside the shaft via a rotating shaft. A cleaning seat is fixedly connected to the outer wall of the sleeve. A horizontal groove is symmetrically formed on the front surface of the cleaning seat. A sliding rod is fixedly connected inside the horizontal groove. A slider is slidably mounted on the outer wall of the sliding rod. A cleaning brush is fixedly connected to the front surface of the slider. An L-shaped abutment rod is fixedly connected to the rear surface of the slider. The end of the L-shaped abutment rod away from the slider contacts the outer wall of the abutment plate. The slider and the transverse groove are fixedly connected together by a spring on the opposite side and outside the slide rod.

[0006] Furthermore, an installation plate is integrally formed on the upper surface of the back surface of the snap-fit ​​mesh cover, a motor is fixedly connected to the upper surface of the installation plate, and the bottom end of the output shaft of the motor extends through to the lower part of the installation plate and is fixedly connected to a bevel gear.

[0007] Furthermore, a second bevel gear is fixedly connected to the rear end of the shaft column, and the outer side wall of the first bevel gear meshes with the outer side wall of the second bevel gear.

[0008] Furthermore, an installation plate two is integrally formed on the lower rear surface of the snap-fit ​​mesh cover, and a dust pump is fixedly installed on the lower surface of the installation plate two. The output end of the dust pump extends through to the inside of the snap-fit ​​mesh cover and is fixedly connected to the dust cover.

[0009] Furthermore, clamping plates are provided on both sides of the inner side of the snap-fit ​​mesh cover. The opposite sides of the two clamping plates are rotatably connected to screw rods 2 via rotating shafts. The opposite ends of the two screw rods 2 pass through to both sides of the snap-fit ​​mesh cover and are fixedly connected to turntables. The screw rods 2 are threadedly connected to the snap-fit ​​mesh cover.

[0010] Furthermore, guide rods are symmetrically fixed on opposite sides of the two clamping plates, and the opposite ends of the two guide rods extend through to both sides of the locking mesh cover and are slidably connected to the locking mesh cover.

[0011] Furthermore, rubber pads are fixedly connected to the opposite sides of both clamping plates.

[0012] Furthermore, a knob is fixedly connected to the front end of the screw, and symmetrical limit grooves are opened on the outer side wall of the shaft. Limit blocks are fixedly connected inside the sleeve and inside both of the limit grooves.

[0013] A method for installing and using the anti-clogging and dust removal device for the heat dissipation system of engineering machinery as described above includes the following steps: S1: Align the snap-fit ​​mesh cover with the air inlet of the radiator of the construction machinery, rotate the turntables on both sides to drive the screw to rotate, and push the two clamping plates to move relative to each other until the rubber pads are tightly against the inner walls on both sides of the air inlet, thus completing the device fixation; S2: Turn the knob to drive the screw to rotate, push the sleeve to move axially along the shaft column, adjust the front and rear position of the cleaning seat until the cleaning brush is in contact with the surface of the filter screen; S3: Start the motor and vacuum pump. The motor drives the shaft and cleaning seat to rotate through the bevel gear transmission. The cleaning brush performs radial reciprocating motion while rotating, cleaning the filter screen in all directions. The vacuum pump collects the cleaned dust through the vacuum hood. S4: After cleaning is complete, turn off the motor and vacuum pump, and dispose of the collected dust properly.

[0014] A cleaning control method for the anti-clogging and dust removal device of the heat dissipation system of engineering machinery as described above includes the following steps: S1: Start the motor, and drive the shaft to rotate at a preset speed through the meshing transmission of bevel gear one and bevel gear two; S2: The shaft drives the sleeve and cleaning seat to rotate synchronously, and the L-shaped abutment rod slides on the outer wall of the abutment plate; S3: When the L-shaped abutment rod slides into the arc opening, the spring pushes the slider to slide outward along the slide rod, causing the cleaning brush to move outward; S4: When the L-shaped abutment rod slides out of the arc opening, the abutment plate squeezes the L-shaped abutment rod, causing the slider to compress the spring and slide inward, thus realizing the radial reciprocating motion of the cleaning brush; S5: The cleaning brush, through a combination of rotation and radial reciprocating motion, evenly sweeps the surface of the filter screen while simultaneously activating the dust pump to collect dust.

[0015] The technical solution of this invention achieves a composite motion of rotation and radial reciprocating motion of the cleaning brush through the coordinated operation of the shaft, abutment plate, cleaning seat, L-shaped abutment rod, and spring. This completely eliminates the central dead angle and edge blind spot present in traditional fixed rotary cleaning brushes, achieving a cleaning coverage rate of 100% and efficiently removing various dust and debris adhering to the filter screen surface. Through the threaded transmission structure of the screw and sleeve, the front and rear positions of the cleaning brush can be flexibly adjusted, precisely controlling the fit between the bristles and the filter screen, ensuring both cleaning effect and avoiding excessive wear on the filter screen. The entire structure adopts a purely mechanical transmission structure, ensuring stable and reliable operation with a low failure rate. It can adapt to harsh working environments such as vibration and dust in engineering machinery, effectively preventing filter screen clogging and ensuring stable ventilation of the heat dissipation system.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. 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 indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] Example 1 like Figures 1-7 As shown, this embodiment provides a dust removal and anti-clogging device for a heat dissipation system of engineering machinery, including a snap-fit ​​mesh cover 1. A shaft column 2 is rotatably installed at the center of the inner side of the snap-fit ​​mesh cover 1 via a rotating shaft. An abutment plate 3 is fixedly connected to the inner side of the snap-fit ​​mesh cover 1 and located outside the shaft column 2. Multiple arc-shaped openings 4 are provided on the outer side of the abutment plate 3.

[0022] A screw 5 is threaded inside the shaft 2. A sleeve 6 is rotatably mounted on the outer wall of the screw 5, located outside the shaft 2, via a rotating shaft. A cleaning seat 7 is fixedly connected to the outer wall of the sleeve 6. A transverse groove 8 is symmetrically formed on the front surface of the cleaning seat 7. A slide rod 9 is fixedly connected inside the transverse groove 8. A slider 10 is slidably mounted on the outer wall of the slide rod 9. A cleaning brush 11 is fixedly connected to the front surface of the slider 10. An L-shaped abutment rod 12 is fixedly connected to the rear surface of the slider 10. The end of the L-shaped abutment rod 12 away from the slider 10 contacts the outer wall of the abutment plate 3. A spring 28 is fixedly connected to both the slider 10 and the transverse groove 8, located outside the slide rod 9.

[0023] A mounting plate 13 is integrally formed on the upper rear surface of the snap-fit ​​cover 1. A motor 14 is fixedly connected to the upper surface of the mounting plate 13. The bottom end of the output shaft of the motor 14 extends through to the lower part of the mounting plate 13 and is fixedly connected to a bevel gear 15. A bevel gear 16 is fixedly connected to the rear end of the shaft column 2. The outer side wall of the bevel gear 15 meshes with the outer side wall of the bevel gear 16.

[0024] A mounting plate 17 is integrally formed on the lower rear surface of the snap-fit ​​mesh cover 1. A vacuum pump 18 is fixedly mounted on the lower surface of the mounting plate 17. The output end of the vacuum pump 18 extends through to the inside of the snap-fit ​​mesh cover 1 and is fixedly connected to the vacuum cover 19.

[0025] The mesh cover 1 has clamping plates 20 on both sides inside. Each clamping plate 20 has a screw 21 rotatably connected to its opposite sides via a pivot. The opposite ends of the two screws 21 pass through both sides of the mesh cover 1 and are fixedly connected to a turntable 22. The screws 21 are threadedly connected to the mesh cover 1. Guide rods 23 are symmetrically fixed to the opposite sides of each clamping plate 20. The opposite ends of the two guide rods 23 pass through both sides of the mesh cover 1 and are slidably connected to it. Rubber pads 24 are fixedly connected to the opposite sides of each clamping plate 20.

[0026] A knob 25 is fixedly connected to the front end of the screw 5. Limiting grooves 26 are symmetrically opened on the outer side wall of the shaft 2. Limiting blocks 27 are fixedly connected inside the sleeve 6 and inside the two limiting grooves 26.

[0027] When using this device: Before use, align the snap-fit ​​mesh cover 1 with the air inlet of the radiator of the construction machinery, and rotate the turntables 22 on both sides. The turntables 22 drive the screw 21 to rotate on the snap-fit ​​mesh cover 1. Since the screw 21 is threadedly connected to the snap-fit ​​mesh cover 1, and the clamping plate 20 is slidably engaged with the snap-fit ​​mesh cover 1 through the guide rod 23, the rotation of the screw 21 will push the two clamping plates 20 to move relative to each other until the rubber pads 24 on the clamping plates 20 are tightly pressed against the inner walls on both sides of the air inlet, thus achieving the fitting and fixing of the snap-fit ​​mesh cover 1 with air inlets of different sizes. The rubber pads 24 can increase the friction between the clamping plates 20 and the inner wall of the air inlet, improve the fixing stability, and at the same time prevent the clamping plates 20 from causing wear to the air inlet.

[0028] After fixing, according to the size of the filter screen inside the mesh cover 1, turn the knob 25 to drive the screw 5 to rotate inside the shaft 2. Since the screw 5 is threadedly connected to the shaft 2, and the sleeve 6 slides with the limiting groove 26 of the shaft 2 through the limiting block 27, when the screw 5 rotates, it will push the sleeve 6 to move back and forth along the shaft 2 axis, thereby driving the cleaning seat 7 and the cleaning brush 11 to adjust their positions back and forth until the cleaning brush 11 is in contact with the surface of the filter screen.

[0029] After adjustment, start motor 14. The output shaft of motor 14 drives bevel gear 15 to rotate. Bevel gear 15 meshes with bevel gear 16, driving the shaft 2, sleeve 6, and cleaning seat 7 to rotate synchronously. When cleaning seat 7 rotates, L-shaped abutment rod 12 slides on the outside of abutment plate 3. When L-shaped abutment rod 12 slides into the arc opening 4 of abutment plate 3, spring 28 pushes slider 10 to slide along slide rod 9, driving cleaning brush 11 to move outward. When L-shaped abutment rod 12 slides out of arc opening 4, the outer wall of abutment plate 3 presses L-shaped abutment rod 12, driving slider 10 to compress spring 28 and move inward, thus realizing the reciprocating movement of cleaning brush 11. Combined with the rotation of cleaning seat 7, this ensures a thorough and even cleaning of the filter screen, guaranteeing a cleaning effect.

[0030] While the cleaning brush 11 cleans the filter, the vacuum pump 18 is activated. The vacuum pump 18 generates negative pressure through the vacuum hood 19, promptly sucking the dust cleaned by the cleaning brush 11 into the vacuum pump 18. A storage bag or collection box can be connected to the input end of the vacuum pump 18 to achieve centralized dust collection and prevent dust from being dispersed again into the inside of the mesh cover 1 or the heat dissipation system of the engineering machinery. After cleaning is completed, the vacuum pump 18 is turned off, and the collected dust is disposed of properly.

[0031] During disassembly, rotate the turntable 22 in the opposite direction to separate the clamping plate 20, and then remove the device from the air inlet.

[0032] Compared with existing technologies: This invention, through the coordinated arrangement of the clamping plate, screw two, and guide rod, allows for flexible adjustment of the clamping distance, adapting to air inlets of different sizes of engineering machinery radiators. This significantly improves the versatility and ease of assembly of the device, eliminating the need for separate dust removal devices for different specifications of air inlets and reducing operating costs.

[0033] The rubber pad in this invention can increase the friction during clamping, improve the stability of the device after it is fixed, and prevent the clamping parts from causing wear to the air inlet, thus protecting the structural integrity of the air inlet of the heat dissipation system.

[0034] This invention achieves comprehensive and uniform cleaning of the filter screen through the synergistic action of the cleaning brush, cleaning seat, motor, bevel gear set, abutment plate, and spring. It effectively removes dust and blockages from the filter screen surface, ensures smooth airflow at the air inlet, avoids reduced heat dissipation efficiency due to filter screen blockage, and prevents problems such as reduced power and component damage caused by overheating of core components of engineering machinery.

[0035] The dust pump and dust hood of this invention can collect dust generated during the cleaning process in a timely manner, preventing dust from being dispersed into the heat dissipation system or the surrounding environment, reducing the wear and pollution of heat dissipation components by dust, reducing the frequency of equipment maintenance, extending the service life of radiators and core components of engineering machinery, and improving the environmental friendliness of dust removal operations.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
