[0032] like Figures 1 to 4 As shown, according to a first aspect of the present invention, a tractor air intake system is provided, the tractor air intake system including an air pre-filter 100.

[0033] In the following description, reference will be made to Figures 1 to 4 The specific structure of the aforementioned components of the tractor's air intake system and their connection relationships are described in detail.

[0034] like Figures 1 to 4 As shown, in this embodiment, the air pre-filter 100 in the tractor's air intake system is used for preliminary filtration of air containing dust. The air pre-filter 100 may include an outer screen 1, a filter element 2, and a dust collection basin 3. The outer screen 1 of the air pre-filter 100 may be installed in the middle of the pre-filter housing. The filter element 2 may be located inside the outer screen 1. The filter element 2 may be provided with an air inlet 20, through which air passing through the outer screen 1 can enter the filter element 2. The dust collection basin 3 may be installed at the lower part of the pre-filter housing, and the bottom end of the filter element 2 is connected to the dust collection basin 3. This arrangement ensures that dust-containing air entering the air pre-filter 100 is filtered by the filter element 2, and the separated dust falls into the dust collection basin 3 for storage, preventing dust from being directly discharged into the air and polluting the working environment.

[0035] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the outer mesh 1 can be a cylindrical structure used to block larger-diameter debris in the air. Multiple filter components 2 can be present, and their bottoms can be connected to the dust collection basin 3. The air pre-filter 100 may also include a dust discharge cover 31 and a snap-fit ​​structure 32. Specifically, a dust discharge cover 31 can be provided at the bottom of the dust collection basin 3 to remove dust stored in it. The first side of the dust discharge cover 31 can be pivotally connected to the dust collection basin 3. Multiple dust discharge covers 31 can be provided on different sides of the bottom of the dust collection basin 3. The snap-fit ​​structure 32 is used to fix the dust discharge cover 31 to the dust collection basin 3. The snap-fit ​​structure 32 can include two parts: one part is provided on the second side of the dust discharge cover 31, and the other part is provided on the dust collection basin 3. When the snap-fit ​​structure 32 is unlocked, the dust discharge cover 31 can pivot around the second side, thereby discharging the dust stored in the dust collection basin 3. When the snap-fit ​​structure 32 is locked, the dust cover 31 can be fixed to the dust collection basin 3.

[0036] Furthermore, preferably, in this embodiment, the dust collection basin 3 can be made of a transparent material so that workers can easily see the amount of dust stored in the dust collection basin 3, and thus be able to remove the dust stored in the dust collection basin 3 in a timely manner. Specifically, the dust collection basin 3 can be made of transparent materials such as plastic or glass.

[0037] Preferred, such as Figure 1As shown, in this embodiment, the filter component 2 may include a first tube 21, a second tube 22, an upper plate 4, and guide vanes 23. The bottom end of the first tube 21 may be connected to the dust collection basin 3. The bottom end of the first tube 21 may be conical and have a dust outlet. Dust leaking from the first tube 21 will fall into the dust collection basin 3. The bottom end of the second tube 22 may be inserted into the top end of the first tube 21, and the diameter of the second tube 22 is smaller than the diameter of the top end of the first tube 21. The air inlet 20 may be formed between the top end of the first tube 21 and the outer wall of the second tube 22. The upper plate 4 may be annular. A first passage opening may be formed in the center of the upper plate 4 for the air outlet 6 to pass through. The upper plate 4 may also have multiple first connecting holes. The top ends of the multiple second tubes 22 may be respectively inserted into the multiple first connecting holes. Preferably, the multiple second tubes 22 may be integrally formed with the upper plate 4. The lower plate portion 40 can be formed in an annular shape. A second passage opening can be formed in the center of the lower plate portion 40 for the air pipe 6 to pass through. Multiple second connecting holes can also be provided on the lower plate portion 40. The bottom ends of multiple first pipe portions 21 can be respectively inserted into multiple second connecting holes. Preferably, the multiple first pipe portions 21 can be integrally formed with the lower plate portion 40. A guide vane 23 can be disposed between the inner sidewall of the first pipe portion 21 and the outer sidewall of the second pipe portion 22. Specifically, the guide vane 23 can be disposed at the air inlet 20. The second pipe portion 22 can have a diameter change at a corresponding position, and the diameter of the first pipe portion 21 gradually decreases in the vertically downward direction, thereby limiting the guide vane 23. The guide vane 23 separates air and dust by rotation, causing the dust to fall into the dust collection basin 3 through the bottom end of the first pipe portion 21.

[0038] Preferred, such as Figure 1 As shown, in this embodiment, the air pre-filter 100 may further include an upper cover 5 and an air outlet pipe 6. The upper cover 5 covers the top of the upper plate 4 and may be connected to the upper plate 4 by screws. The upper cover 5 and the upper plate 4 enclose an air outlet chamber. After air and dust are separated, the air enters the air chamber through the top end of the second pipe 22. The top end of the air outlet pipe 6 passes through the first through-hole of the upper plate 4 and communicates with the air chamber. The bottom end of the air outlet pipe 6 may pass through the middle of the dust collection basin 3.

[0039] Preferred, such as Figure 1 As shown, in this embodiment, the pre-filter housing may include an upper baffle ring 11 and a lower baffle ring 10. The upper baffle ring 11 can be fitted onto the outer periphery of the upper plate portion 4. The top end of the outer mesh 1 can be installed on the upper baffle ring 11. The lower baffle ring 10 can be fitted onto the outer periphery of the lower plate portion 40. The bottom end of the outer mesh 1 can be installed on the lower baffle ring 10.

[0040] Preferred, such as Figure 1 As shown, in this embodiment, the cross-section of the ash collection basin 3 can be formed as an annular shape. That is, a circular opening can be formed in the middle of the ash collection basin 3, and the bottom end of the air outlet pipe 6 can pass through the circular opening. The gas in the air chamber can flow to the air filter 200 through the air outlet pipe 6.

[0041] Preferred, such as Figures 2 to 4 As shown, in this embodiment, the tractor's air intake system further includes an air filter 200, a hood 9, and a turbocharger intake hose 8. The air filter 200 can be located inside the hood 9. The air filter 200 can be connected to the air pre-filter 100 via an intake pipe 7. Specifically, the intake pipe 7 can include a pre-filter outlet hose 71, an air filter intake steel pipe weld 72, and an air filter intake hose 73. The exhaust pipe of the air pre-filter 100 can be connected to the air filter 200 in sequence via the pre-filter outlet hose 71, the air filter intake steel pipe weld 72, and the air filter intake hose 73. The air filter 200 can be connected to the turbocharger via the turbocharger intake hose 8. In the prior art, the tractor's engine air compressor originally required a separate air filter to filter the incoming air, which was costly and inconvenient to maintain. In the tractor's air intake system, the engine air compressor can share the air filter 200 with the engine intake pipe 300, and take air from the outlet of the turbocharger intake hose 8, which then enters the air compressor through the air pump intake hose, thus saving costs and facilitating maintenance.

[0042] Preferred, such as Figures 2 to 4 As shown, in this embodiment, the turbocharger intake hose 8 can be connected to the end of the air filter 200 along its length. The intake pipe 7 can be connected to the side of the air filter 200 in the circumferential direction. A maintenance indicator for detecting vacuum level can be provided at the connection point between the air filter 200 and the turbocharger intake hose 8. During use, when dust clogs the filter element of the air filter 200, the maintenance indicator detects a vacuum level of 6Ka-6.5Ka and triggers an alarm, allowing personnel to promptly perform maintenance on the air filter 200.

[0043] Preferred, such as Figures 2 to 4 As shown, in this embodiment, the rated intake flow rate of the tractor intake system can be 830 m³ / h. 3 / h. The air filter 200 can be formed in a cylindrical shape, and the length of the air filter 200 can be from 413mm to 421mm. Further, preferably, the air filter 200 can be placed horizontally inside the hood 9 (i.e., arranged along the width direction of the vehicle). The end cap 201 of the air filter 200 can be set facing the hood 9. This arrangement allows the operator to directly maintain the air filter 200 after opening the hood 9. In the prior art, since the hood is a one-piece hood, it is not possible to disassemble parts of the hood separately, and the air filter is difficult to maintain due to obstruction. However, in the tractor intake system, the cylindrical air filter 200, due to its shortened overall length and the relocation of the air filter 200 to the side of the engine closer to the front of the tractor, eliminates the need to disassemble other parts. After opening the hood 9, the end cap 201 of the air filter 200 can be directly opened for maintenance, thereby reducing the difficulty of maintenance.

[0044] In addition, such as Figures 2 to 4 As shown, according to a second aspect of the present invention, a tractor is provided, the tractor including an engine and a tractor intake system as described above, wherein the air filter 200 is disposed on the side of the engine near the front of the tractor.

[0045] During use, the air pre-filter 100 has a transparent dust collection basin 3 at its bottom, allowing the separated dust to be stored in the basin, preventing it from being directly released into the air and polluting the working environment. Once the dust collection basin is full, the operator can open the dust discharge cover 31 to release the dust. Furthermore, in the tractor's intake system, the air filter 200 is located on the side of the engine near the front of the tractor, and is horizontally positioned inside the engine cover 9, shortening its overall length. This ensures that the air filter 200 is not obstructed by other parts, and the end cover 201 of the air filter 200 can be directly opened after opening the engine cover 9 for maintenance, reducing maintenance difficulty.

[0046] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application.
