This causes a large amount of impurities such as dust and sediment to easily enter the interior of the cab through the ventilation openings during the excavation process of the excavator. When the driver is in a dusty environment for a long time, a large amount of these particulate matters will be inhaled, which affects health. For this reason, the utility model proposes a side door of an excavator with a filtering function. Content of the Utility Model

[0027] Such as Figure 1 And Figure 2As shown in the figure, a side door with a filtering function proposed by the present utility model for an excavator includes: a side door 1, and a handle is provided on the side door 1 for easy opening and closing. A transparent window 2 is provided on the side door 1, and the transparent window 2 is of a pull-out type for easy ventilation and observing the external situation of the cab. A hinge cylinder 3 is fixedly provided on one side of the side door 1 for facilitating the installation of the side door 1 on the excavator; a ventilation plate 4 fixedly penetrating through the side door 1 for ventilation, and the interior of the ventilation plate 4 is hollow. A ventilation hole 5 is provided on one side of the ventilation plate 4, and a plurality of ventilation holes 5 are provided for facilitating the entry of external air into the excavator cab. A filtering assembly 6 for filtering air impurities is provided inside the ventilation plate 4, which can filter the impurities in the external air; a baffle 7 is provided inside the ventilation plate 4, and the baffle 7 is connected to the ventilation plate 4 by bolts for easy installation and disassembly. An air inlet hole 8 is provided on the baffle 7 for facilitating the entry of air into the excavator cab.

[0028] As Figure 3 and Figure 4 shown in the figure, the filtering assembly 6 includes guide rods 61 fixedly provided inside the ventilation plate 4, and multiple groups of guide rods 61 are provided. A first filter plate 62 and a second filter plate 63 are provided between the guide rods 61. Guide blocks 64 are fixedly provided on both sides of the first filter plate 62 and the second filter plate 63, and the guide blocks 64 are slidably connected to the guide rods 61 to guide the second filter plate 63 and make the horizontal movement of the second filter plate 63 more stable. A first cleaning strip brush 65 is fixedly provided on one end side of the first filter plate 62, and the first cleaning strip brush 65 is in close contact with the second filter plate 63 for facilitating the cleaning of the second filter plate 63 during the movement process. The second filter plates 63 are fixedly connected by a connecting block 66 provided, and a fixing rod 67 is fixedly provided on one side of the connecting block 66, and there are two fixing rods 67 and they are symmetrically arranged. A second cleaning strip brush 68 is fixedly provided at one end of the fixing rod 67, and the second cleaning strip brush 68 is in close contact with the first filter plate 62 for facilitating the cleaning of the surface of the first filter plate 62 during the movement process. A spring 69 is sleeved on the outer wall of the guide rod 61, one end of the spring 69 is fixedly connected to the inner wall of the ventilation plate 4, and the other end of the spring 69 is fixedly connected to the guide block 64 for facilitating the reset of the second filter plate 63.

[0029] Furthermore, guide grooves 9 are provided on the inner wall of the ventilation plate 4, and the guide grooves 9 are symmetrically arranged. A collection box 10 is provided between the guide grooves 9, and the collection box 10 is located directly below the filtering assembly 6. Guide blocks 11 are fixedly provided on both sides of the collection box 10, and the guide blocks 11 are slidably connected to the guide grooves 9, which can guide the movement of the collection box 10 to centrally collect the impurities cleaned, facilitating the treatment.

[0030] Secondly, a rain shield 12 is provided above the ventilation hole 5, and the rain shield 12 is of an arc-shaped structure to prevent rainwater from entering the interior of the excavator cab through the ventilation hole 5.

[0031] Furthermore, the first filter plate 62 and the second filter plate 63 are each provided with three layers and are staggered with each other, capable of filtering external air multiple times, and can purify air or liquid more effectively. Each layer can intercept particles of a specific size, thereby improving the overall filtration efficiency.

[0032] In addition, a handle 13 is fixedly provided on one side of the second filter plate 63, facilitating manual pushing of the second filter plate 63 to move and improving the cleaning efficiency.

[0033] The working principle of this embodiment is as follows: External air enters the interior of the ventilation plate 4 through the filter assembly 6, is filtered by the three-layer first filter plate 62 and the second filter plate 63, and the impurities in the air are filtered on the surface. The clean air enters the excavator cab through the air inlet holes 8.

[0034] Further, long-term filtration causes impurities to accumulate on the outer sides of the first filter plate 62 and the second filter plate 63. By manually pushing the handle 13, the handle 13 drives the second filter plate 63 to move. The second filter plate 63 drives the guide block 64 to slide horizontally on the guide rod 61. During the movement of the second filter plate 63, it is in close contact with the first cleaning strip brush 65, causing the first cleaning strip brush 65 to clean the dust accumulated on the outer side of the second filter plate 63. At the same time, the second filter plate 63 drives the second cleaning strip brush 68 to move horizontally through the connecting block 66 and the fixing rod 67, causing the second cleaning strip brush 68 to clean the dust accumulated on the outer side of the first filter plate 62. The cleaned dust falls into the collection box 10 due to gravity, and by adding a certain amount of water to the collection box 10, the dust falls into the water, thereby being centrally collected and preventing it from entering the air again. This improves the effect of filtering air, greatly reduces the dust content inside the cab, effectively improves the working environment of the driver, reduces the risk of the driver inhaling harmful particulate matter, and helps to protect the respiratory health of the driver.

[0035] The above specific embodiments are merely several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
