Description

Technical Field

[0001] This utility model relates to oil pumps, and in particular to a special oil pump for wheeled tractors suitable for steep slopes in mountainous areas. Background Technology

[0002] With the advancement of agricultural modernization, wheeled trailers are gradually being promoted in mountainous and plateau regions. Due to the limitations of their chassis structure, and the fact that their engines operate at steep inclines in these areas, the requirements for engine tilt angle control are very high. At steep inclines, the oil pump is extremely prone to failing to draw oil, leading to lubrication failure and damage to moving engine components. Currently, wheeled trailers have very strict requirements for operating in environments with steep inclines, which necessitates that the oil pump maintain its optimal oil suction position at different tilt angles.

[0019] like Figure 1 and Figure 2As shown, a special oil pump for wheeled tractors suitable for steep slopes in mountainous areas includes a drive component 1, an oil suction pump body 2, an oil suction pipe 3, and an oil outlet pipe 4. The drive component 1 is mounted on the oil suction pump body 2, which has an oil inlet. The oil suction pipe 3 is sealed and installed at the oil inlet. The oil suction pump body 2 also has an oil outlet, and the oil outlet pipe 4 is installed at the oil outlet. In this embodiment, the oil suction pump body 2 includes an oil suction shell 21 with an open opening and a cover plate 24. The cover plate 24 seals the open opening of the oil suction shell 21. A drive gear 23 and a driven gear 22 are rotatably mounted inside the oil suction shell 21. The drive gear 23 and the driven gear 22 mesh, and the drive component 1 is connected to the drive gear 23. In this embodiment, the drive component 1 achieves power transmission with the transmission system of the wheeled tractor. That is, when the engine of the wheeled tractor starts, the drive component 1 rotates, thereby causing the drive gear 23 and the driven gear 22 to rotate. After the wheel 23 and driven gear 22 rotate, a negative pressure is formed in the oil suction shell 21, and the engine oil is sucked into the oil suction shell 21 under the action of the negative pressure, and then enters the oil supply system through the oil outlet. In this embodiment, the oil suction pipe 3 includes a first pipe body 34 and a second pipe body 35. The first pipe body 34 and the second pipe body 35 are connected at an angle to each other, and the first pipe body 34 is sealed in the oil outlet. The second pipe body 35 has an inwardly bent section, and an oil suction cover 31 is installed at the oil inlet of the second pipe body 35. Through the first pipe body 34 and the second pipe body 35, the oil suction position can be adjusted, increasing the original limit oil suction angle from 20° to 45°. This not only adapts to the working conditions of agricultural machinery under large tilt angles, but also reduces manufacturing costs, saves layout space, makes full use of the limited space of the existing wheel-mounted oil pan, meets market requirements, and is more in line with the design requirements of modern small internal combustion engines.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, a support member 5 is installed on the cover by screws. The other end of the support member 5 is provided with an arc-shaped groove. The second tube 35 is locked in the arc-shaped groove. The support member 5 lifts the second tube 35, thereby ensuring the installation position of the second tube 35. This ensures the stability of the position during use and thus ensures the reliability of oil suction.

[0021] In this embodiment, as Figure 2 As shown, the insertion end of the first tube 34 is provided with an annular sealing groove, and a sealing ring 33 is installed in the annular sealing groove. The sealing ring 33 seals the first tube 34 with the oil suction shell 21, thereby preventing oil leakage and ensuring the reliability of oil suction.

[0022] In this embodiment, as Figure 2 As shown, the oil outlet pipe 4 is equipped with a flange at the oil inlet end, and the oil outlet pipe 4 is connected to the oil suction shell 21 through the flange, which makes it convenient to connect the oil outlet pipe 4 and the oil suction shell 21.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, a fixing plate 32 is also provided on the first tube body 34. The fixing plate 32 is detachably installed on the oil suction pump body 2 by locking screws. A through hole is provided at one end of the fixing plate 32 away from the first tube body 34. In this embodiment, a latch corresponding to the through hole is provided on the oil filling shell. A screw hole is provided on the latch. In this embodiment, the screw hole is a through hole that extends upward and penetrates the cover. Therefore, the fixing plate 32, the oil suction shell 21 and the cover plate 24 can be connected by a set of bolt assemblies.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
