Description

Technical Field

[0001] This utility model relates to the field of air intake grille technology, and in particular to the air intake grille at the radiator end. Background Technology

[0002] Air intake grilles often employ honeycomb or elongated structures. They prevent large stones or other debris from entering the radiator, protecting it and other internal components from damage. Air intake grilles allow air to enter the radiator, helping it to effectively dissipate heat and cool down. They are commonly used at the radiator end of various engineering machinery.

[0003] In existing air intake grilles, the grille plate is usually installed inside an outer frame, and then the outer frame is installed at the air inlet of the radiator of the engineering equipment through connectors. This allows the grille plate to completely cover the air inlet of the radiator, allowing air to pass through the grille plate and enter the radiator. At the same time, the grille plate intercepts external debris, preventing it from entering the radiator and damaging its internal components.

[0004] However, large amounts of debris will adhere to the surface of the grille after being intercepted by it, causing the grille holes to be blocked. This prevents outside air from passing through the grille and entering the radiator, thus affecting the normal use of the grille. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a radiator end air intake grille.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a radiator-end air intake grille, including an outer frame, a grille plate disposed inside the outer frame, a cleaning device disposed on one side of the outer frame, a sealing device disposed on one side of the outer frame, the cleaning device including a first rectangular rod, the first rectangular rod being fixedly connected to the outer frame, a second rectangular rod being fixedly connected to the side of the outer frame away from the first rectangular rod, a plurality of intercepting rods being fixedly connected between the first rectangular rod and the second rectangular rod, a first circular hole block being fixedly connected to one side of the first rectangular rod, a motor being fixedly connected to one side of the first circular hole block, a screw being fixedly connected to the output end of the motor, the screw being located inside the first circular hole block, a screw hole rod being threadedly connected to the surface of the screw, the screw hole rod being located between the plurality of intercepting rods and the grille plate, a plurality of scraping rods being fixedly connected to one side of the screw hole rod, the plurality of scraping rods being respectively located between two adjacent intercepting rods.

[0007] The effect achieved by the above-mentioned components is as follows: By setting up a cleaning device, when large-area debris moves towards the grating plate, multiple interceptor bars intercept the incoming debris, separating it from the grating plate surface. At this time, the motor is activated, causing the motor to drive the screw to rotate, which in turn drives the screw hole rod to move up and down. The screw hole rod then drives multiple scraper bars to move up and down, causing the scraper bars to move up and down along the gaps between the interceptor bars and scrape off the large-area debris adhering to them. This achieves the interception and rapid cleaning of large-area debris, reducing the likelihood of large-area debris adhering to the grating plate surface, causing the grating plate holes to become blocked and hindering airflow, thus preventing outside air from smoothly passing through the grating plate into the radiator. This improves the utilization efficiency of the grating plate.

[0008] Preferably, one end of each of the plurality of scraper rods is fixedly connected to a rubber block, and the surface of each of the plurality of rubber blocks is provided with a plurality of rubber protrusions.

[0009] The effect achieved by the above components is that by setting rubber blocks, the rubber blocks and multiple rubber protrusions can increase the contact friction between the scraper and the debris, reducing the slippage of debris on the scraper surface when the scraper is scraping away debris.

[0010] Preferably, a second circular hole block is fixedly connected to one side of the second rectangular rod, and the surface of the screw at the end away from the motor is rotatably connected to the inner wall of the second circular hole block.

[0011] The effect achieved by the above-mentioned components is that by setting the second circular hole block, the second circular hole block can wrap around and assist in limiting the screw on the side away from the motor during use, thereby reducing the shaking of the screw on the side away from the motor during use.

[0012] Preferably, a guide rod is fixedly connected between the first rectangular rod and the second rectangular rod, and a third circular hole block is fixedly connected to the end of the screw rod away from the screw rod, and the surface of the guide rod is slidably connected to the inner wall of the third circular hole block.

[0013] The effect achieved by the above components is as follows: by setting the guide rod and the third circular hole block, the guide rod can be located inside the third circular hole block to assist in limiting the screw rod on the side away from the screw, reducing the wobbling or rotation of the screw rod during the process of being driven by the screw, and improving the stability of the screw rod on the side away from the screw.

[0014] Preferably, a plurality of through holes are provided on one side of the second rectangular rod, and the plurality of through holes are arranged at equal intervals.

[0015] The effect achieved by the above-mentioned components is that by setting through holes, impurities or dust accumulated on the second rectangular rod can be discharged through multiple through holes, thereby reducing the accumulation of dust and impurities on the second rectangular rod.

[0016] Preferably, the sealing device includes a screw hole L-plate, which is fixedly connected to the outer frame. A bolt is threaded onto the inner wall of the screw hole L-plate, and a pressure plate is rotatably connected to one end of the bolt. A rubber pad is fixedly connected to the side of the pressure plate near the outer frame, and the rubber pad and the pressure plate are located at the edge of the outer frame.

[0017] The effect achieved by the above components is as follows: By setting up a sealing device, the outer frame is first assembled and fixed to the external radiator end. At this time, the bolt is manually rotated, so that the bolt moves along the inner wall of the bolt hole L plate towards the outer frame. This causes the bolt to move the pressure plate, which in turn moves the rubber pad. When the rubber pad moves to the position where it is in contact with the surface of the outer frame, the pressure plate continues to squeeze the rubber pad. Under the squeezing action of the pressure plate, the rubber pad is tightly attached to the surface of the outer frame and the radiator. This allows the rubber pad, together with the pressure plate, to seal the gap at the connection between the outer frame and the radiator. This reduces the large gap between the outer frame and the radiator end after assembly, which would otherwise allow external dust and impurities to seep in through the gap with the airflow. This improves the sealing performance of the assembly between the outer frame and the radiator end.

[0018] Preferably, a screw block is fixedly connected to the end of the bolt away from the pressure plate, and multiple anti-slip protrusions are fixedly connected to the surface of the screw block.

[0019] The effect achieved by the above components is that by setting the tightening block, the contact area of ​​the bolt can be increased, allowing personnel to easily rotate the bolt by manually turning the tightening block.

[0020] Preferably, one side of the pressure plate is fixedly connected with a plurality of reinforcing ribs, and the plurality of reinforcing ribs are arranged at equal intervals.

[0021] The effect achieved by the above components is that by setting reinforcing ribs, the strength of the pressure plate can be increased, reducing the possibility of deformation or breakage of the pressure plate during use.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, a cleaning device can be set up to intercept and clean large areas of debris, reducing the situation where large areas of debris are adsorbed on the surface of the grille, causing the holes of the grille to be blocked and hindering airflow, thus preventing outside air from passing through the grille smoothly into the radiator, thereby improving the utilization efficiency of the grille.

[0029] Reference Figure 1-4 As shown, this embodiment discloses a radiator-end air intake grille, including an outer frame 1, a grille plate 2 disposed inside the outer frame 1, a cleaning device 3 disposed on one side of the outer frame 1, and a sealing device 4 disposed on one side of the outer frame 1. The cleaning device 3 includes a first rectangular rod 31, which is fixedly connected to the outer frame 1. A second rectangular rod 32 is fixedly connected to the side of the outer frame 1 away from the first rectangular rod 31. Multiple intercepting rods 33 are fixedly connected between the first rectangular rod 31 and the second rectangular rod 32. A first circular hole block 34 is fixedly connected to one side of the first rectangular rod 31. A motor 38 is fixedly connected to one side of the first circular hole block 34. A screw 39 is fixedly connected to the output end of the motor 38. The screw 39 is located inside the first circular hole block 34. A screw hole rod 310 is threadedly connected to the surface of the screw 39. The screw hole rod 310 is located between the multiple intercepting rods 33 and the grille plate 2. Multiple scraper rods 311 are fixedly connected to one side of the screw hole rod 310. Rods 311 are located between two adjacent interceptor rods 33. By setting up the cleaning device 3, when large-area debris moves towards the grille plate 2, multiple interceptor rods 33 intercept the incoming large-area debris, separating it from the surface of the grille plate 2. At this time, the motor 38 is started, causing the motor 38 to drive the screw 39 to rotate, which in turn causes the screw 39 to drive the screw hole rod 310 to move up and down. The screw hole rod 310 then drives multiple scraper rods 311 to move up and down, causing the scraper rods 311 to move up and down along the gaps between the multiple interceptor rods 33 and scrape off the large-area debris adhering to the multiple interceptor rods 33. This achieves the interception and rapid cleaning of large-area debris, reducing the situation where large-area debris adheres to the surface of the grille plate 2, causing the holes of the grille plate 2 to be blocked and hindering airflow, thus preventing outside air from smoothly passing through the grille plate 2 into the radiator. This improves the utilization efficiency of the grille plate 2.

[0030] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that one end of each of the multiple scraper rods 311 is fixedly connected to a rubber block 312. The surface of each rubber block 312 is provided with multiple rubber protrusions 313. By setting the rubber blocks 312, the rubber blocks 312 and the multiple rubber protrusions 313 can increase the contact friction between the scraper rod 311 and the debris, reducing the slippage of the debris on the surface of the scraper rod 311 when the scraper rod 311 is scraping the debris. A second round hole block 35 is fixedly connected to one side of the second rectangular rod 32. The surface of the screw 39 away from the motor 38 is rotatably connected to the inner wall of the second round hole block 35. By setting the second round hole block 35, the second round hole block 35 can wrap around the side of the screw 39 away from the motor 38 and assist in limiting it, reducing the shaking of the side of the screw 39 away from the motor 38 during use.

[0031] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a guide rod 37 fixedly connected between the first rectangular rod 31 and the second rectangular rod 32. A third circular hole block 314 is fixedly connected to the end of the screw rod 310 away from the screw 39. The surface of the guide rod 37 is slidably connected to the inner wall of the third circular hole block 314. By setting the guide rod 37 and the third circular hole block 314, the guide rod 37 can be located inside the third circular hole block 314 to assist in limiting the screw rod 310 away from the screw 39, reducing the shaking or rotation of the screw rod 310 during the process of being driven by the screw 39, and improving the stability of the screw rod 310 away from the screw 39. A plurality of through holes 36 are opened on one side of the second rectangular rod 32. The plurality of through holes 36 are arranged at equal intervals. By setting the through holes 36, impurities or dust accumulated on the second rectangular rod 32 can be discharged through the plurality of through holes 36, reducing the accumulation of dust and impurities on the second rectangular rod 32.

[0032] Reference Figure 3 and Figure 4As shown, this embodiment discloses a sealing device 4 including a screw hole L-plate 41, which is fixedly connected to the outer frame 1. A bolt 42 is threaded onto the inner wall of the screw hole L-plate 41, and a pressure plate 43 is rotatably connected to one end of the bolt 42. A rubber pad 44 is fixedly connected to the side of the pressure plate 43 near the outer frame 1. The rubber pad 44 and the pressure plate 43 are located at the edge of the outer frame 1. By setting the sealing device 4, the outer frame 1 is first assembled and fixed to the external radiator end. At this time, the bolt 42 is manually rotated, causing the bolt 42 to move along the inner wall of the screw hole L-plate 41 towards the outer frame 1, thereby causing the bolt 42 to drive the pressure plate. The movement of plate 43 causes the pressure plate 43 to move the rubber pad 44. When the rubber pad 44 moves to the position where it is in contact with the surface of the outer frame 1, the pressure plate 43 continues to squeeze the rubber pad 44, so that the rubber pad 44 is tightly in contact with the outer frame 1 and the surface of the radiator under the squeezing action of the pressure plate 43. This allows the rubber pad 44 to work with the pressure plate 43 to seal the gap between the outer frame 1 and the radiator, reducing the large gap between the two after the outer frame 1 is assembled with the radiator end. This prevents external dust and impurities from seeping in through the gap with the airflow, thus improving the sealing performance of the assembly between the outer frame 1 and the radiator end.

[0033] Reference Figure 3 and Figure 4 As shown, this embodiment discloses that a screw block 46 is fixedly connected to the end of the bolt 42 away from the pressure plate 43. Multiple anti-slip protrusions are fixedly connected to the surface of the screw block 46. By setting the screw block 46, the contact area of ​​the bolt 42 can be increased, so that the personnel can easily rotate the bolt 42 by manually rotating the screw block 46. Multiple reinforcing ribs 45 are fixedly connected to one side of the pressure plate 43. The multiple reinforcing ribs 45 are arranged at equal intervals. By setting the reinforcing ribs 45, the strength of the pressure plate 43 can be increased, reducing the possibility of deformation or breakage of the pressure plate 43 during use.

[0034] Working principle: First, the grille plate 2 is installed inside the outer frame 1. Then, the outer frame 1 is installed at the air inlet position of the radiator end of the engineering equipment through the connector, so that the grille plate 2 completely covers the air inlet of the radiator, allowing air to pass through the grille plate 2 and enter the interior of the radiator. At the same time, the grille plate 2 intercepts external debris, preventing external debris from entering the interior of the radiator and damaging its internal components.

[0035] When large debris from the outside moves towards the grid plate 2, multiple interceptor bars 33 intercept the incoming debris, separating it from the surface of the grid plate 2. At this time, the motor 38 is activated, causing the screw 39 to rotate. The screw 39 then moves the screw hole rod 310 up and down, which in turn moves multiple scraper bars 311 up and down. These scraper bars 311 then move multiple rubber blocks 312 up and down, allowing the scraper bars 311 and rubber blocks 312 to move up and down along the gaps between the multiple interceptor bars 33. This scrapes off the large debris adhering to the multiple interceptor bars 33, thus achieving the interception and rapid cleaning of large debris.

[0036] First, assemble and fix the outer frame 1 to the external heat sink end. Then, manually rotate the screw block 46, causing the screw block 46 to drive the bolt 42 to rotate. This causes the bolt 42 to move along the inner wall of the screw hole L plate 41 towards the outer frame 1, which in turn causes the bolt 42 to move the pressure plate 43. This causes the pressure plate 43 to move the rubber pad 44. When the rubber pad 44 moves to the position where it is in contact with the surface of the outer frame 1, the pressure plate 43 continues to squeeze the rubber pad 44. Under the squeezing action of the pressure plate 43, the rubber pad 44 is tightly attached to the outer frame 1 and the surface of the heat sink, thus sealing the gap between the outer frame 1 and the heat sink in conjunction with the pressure plate 43.
