[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 and Figure 2 As shown, an air intake pipe for a bulldozer air filter includes: an air filter body 20, an air supply pipe 21 fixedly connected to the bottom of the air filter body 20, a first flange 22 fixedly connected to the opening of the air supply pipe 21, and the air supply pipe 21 being able to communicate with the exhaust port of the air filter body 20.

[0029] Vent pipe 23 is detachably connected to the end of gas supply pipe 21. The end of vent pipe 23 is fixedly connected to a second flange 24. The second flange 24 and the first flange 22 can be mated and installed. The first flange 22 and the second flange 24 are mated and installed by bolts. This is existing technology, so it will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an auxiliary structure is provided on the wall of the second flange 24 for fastening the second flange 24 and the first flange 22 together. The auxiliary structure includes: a rotating rod 31, a locking rod 32, a through groove 34, and a stop block 36. The rotating rod 31 is symmetrically arranged on both sides of the second flange 24. The locking rod 32 is symmetrically fixedly connected to the upper and lower walls of each rotating rod 31. The through groove 34 is opened through the side wall of the rotating rod 31. The stop block 36 is slidably connected in the through groove 34. The side wall of the stop block 36 can contact the side wall of the first flange 22.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the rotating rod 31 is a semi-capsule-shaped block, the locking rod 32 is an arc-shaped rod, and the through groove 34 is a cross-shaped groove that can accommodate the sliding of the abutment block 36. The wall surface of the abutment block 36 facing the first flange 22 has anti-slip textures. The abutment block 36 is made of rubber. The auxiliary structure also includes a fixed ring 30, a mounting plate 33, a sleeve block 35, a connecting rod 37, and a screw 38. The fixed ring 30 is annular. The mounting plate 33 is fixedly connected to the end of each locking rod 32. The sleeve block 35 is movably connected to the side wall of the mounting plate 33. The connecting rod 37 is fixedly connected to the wall of the sleeve block 35. The abutment block 36 is fixedly connected to the end of the connecting rod 37. The screw 38 is threadedly connected to the side wall of the mounting plate 33. The fixed ring 30 is in the second... Each side of the flange 24 is symmetrically fixedly connected. The upper and lower walls of the arc surface of the rotating rod 31 are respectively fixedly connected with cylinders that can be inserted into the cavity of the fixed ring 30. The plate 33 is a rectangular plate and is located on the end of the clamping rod 32 facing the other clamping rod 32. The sleeve block 35 is a semi-capsule-shaped block. The side wall of the sleeve block 35 is provided with a circular groove for the screw 38 to penetrate. The side wall of the plate 33 is provided with a threaded groove for the screw 38 to be threaded. The connecting rod 37 is an arc-shaped rod. One end of the connecting rod 37 is fixedly connected to the sleeve block 35, and the other end of the connecting rod 37 is fixedly connected to the abutment block 36. Two identical connecting rods 37 are arranged between the symmetrical rotating rods 31. The two connecting rods 37 are located at opposite corners.

[0032] In practical use, when connecting and installing the vent pipe 23 and the air supply pipe 21, first connect the second flange 24 and the first flange 22 and install them with bolts. After confirming that the second flange 24 and the first flange 22 are sealed, move the symmetrical rotating rod 31 towards the first flange 22. When the rotating rod 31 rotates, it will rotate within the cavity of the fixed ring 30 with its cylindrical wall. The rotating rod 31 will also drive the locking rod 32 and the plate 33 to rotate synchronously. As the plate 33 rotates, it will drive the screw 38, the sleeve block 35, the connecting rod 37, and the abutment block 36 to rotate synchronously. After the plates 33 on both sides are in contact, rotate the screw 38 so that it passes through the sleeve block 35 and also through the threaded groove between the aligned plates 33. As the screw 38 moves, it will... The moving sleeve 35 moves synchronously, which drives the connecting rod 37 and the abutment 36 to move synchronously to the other side. The abutment 36 moves from the through groove 34, and the anti-slip textured surface of the abutment 36 presses against the side wall of the first flange 22. At this time, the abutment 36 will deform as it contacts the first flange 22. When the screw 38 is fully turned until the sleeve 35 no longer shakes, the installation is complete. At this time, the wall of the first flange 22 will contact the wall of the clamp 32. When the air filter body 20 delivers air, the air in the air filter body 20 will be filtered and then delivered to the air delivery pipe 21, and then delivered to the ventilation pipe 23. After the first flange 22 and the ventilation pipe 23 are connected, the other end of the ventilation pipe 23 can be connected to the engine.

[0033] In summary, by setting up an auxiliary structure, the flip-out clamp 32 is used to fit the first flange 22 after being flipped and fixed, thereby improving the fit between the first flange 22 and the second flange 24. In addition, the symmetrical abutment blocks 36 can deform and squeeze the outer wall surface of the first flange 22 to prevent the first flange 22 from falling off. Even if there are loose bolts on the walls of the first flange 22 and the second flange 24, the second flange 24 and the first flange 22 will not leak air.

[0034] like Figure 2 and Figure 5 As shown, the gas supply pipe 21 is in the shape of a round tube, and the ventilation pipe 23 is also in the shape of a round tube. The end of the ventilation pipe 23 can be inserted into the opening of the gas supply pipe 21. A retaining ring 25 is fixedly connected inside the cavity of the gas supply pipe 21. The retaining ring 25 is in the shape of a ring. A filter plate 26 is snapped onto the wall of the retaining ring 25. The filter plate 26 can be located between the retaining ring 25 and the ventilation pipe 23. Multiple identical filter grooves 27 are opened through the wall of the filter plate 26.

[0035] In practical use, before connecting the vent pipe 23 and the air supply pipe 21, the filter plate 26 is placed on the wall of the abutment ring 25 inside the air supply pipe 21, and then the vent pipe 23 is inserted into the air supply pipe 21. At this time, the filter plate 26 will be located between the abutment ring 25 and the end of the vent pipe 23. The front and rear walls of the filter plate 26 are equipped with sealing rings.

[0036] In summary, by setting a detachable filter plate 26, the incoming gas can be filtered when the gas is delivered into the cavity of the air pipe 23 through the gas delivery pipe 21, preventing the air filter body 20 from failing to meet the gas filtration standards due to the filter element not being cleaned in time.

[0037] Working principle: When the air filter body 20 delivers air, the air entering the air filter body 20 will be filtered and then delivered to the air delivery pipe 21, and then delivered to the ventilation pipe 23. The ventilation pipe 23 will then deliver the incoming air into the engine for engine operation.
