Description

Technical Field

[0001] The utility model relates to the technical field of tractor accessories, in particular to a new type of fuel tank breather structure. Background Art

[0002] The fuel tank breather is mainly used to balance the pressure difference between the inside of the fuel tank and the atmosphere, and at the same time has the functions of preventing dust from entering the fuel tank and preventing oil foam from overflowing. Figure 1 Shown in the figure is the fuel tank breather structure of a certain existing tractor. This structure fixes the breather assembly to the bottom of the rear floor weldment through bolts. A filter screen is arranged inside the breather assembly, and a drainage pipe fixed by a hose clamp is arranged outside. This structure has the following deficiencies:

[0003] 1. The breather assembly has many assembled parts, resulting in a high procurement cost;

[0004] 2. Since the position of the breather assembly is relatively low, oil foam easily enters the breather assembly, causing oil leakage;

[0005] 3. If the breather assembly of this structure is damaged and leaks oil, or the drainage pipe drains oil due to excessive oil foam, the oil will flow to the chassis, making it extremely difficult to clean.

[0006] Therefore, it is necessary to develop a new type of fuel tank breather structure. Content of the Utility Model

[0007] The utility model aims to provide a new type of fuel tank breather structure to overcome the above problems or at least partially solve the above problems.

[0008] To achieve the above object, the technical solution of the utility model is specifically implemented as follows:

[0009] The utility model provides a new type of fuel tank breather structure, including a fuel tank, on which a tubing joint assembly is installed. One end of the tubing joint assembly is connected to one end of a tubing, the other end of the tubing is connected to a connecting pipe, and the connecting pipe is fixed to the rear floor weldment and is located at the upper position of the rear floor weldment.

[0010] The rear floor weldment includes a rear floor body and a square pipe. The square pipe is installed on the front side of the rear floor body and is welded and fixed. The connecting pipe is fixedly connected to the upper position of the front side of the square pipe.

[0011] As a further solution of the utility model, one end of the tubing is fixedly connected to the connecting pipe through a hose clamp I, and the other end of the tubing is fixedly connected to the tubing joint assembly through a hose clamp II.

[0012] As a further solution of the utility model, a pipe clamp is sleeved on the tubing, and the pipe clamp is arranged on the front side of the square pipe and is fixed by bolts.

[0013] The utility model provides a new type of fuel tank breather structure, and the beneficial effects are as follows:

[0014] 1. Cancel the breather assembly with more parts and cumbersome assembly, and reduce the production cost;

[0015] 2. Weld a connecting pipe on the square pipe of the rear floor welding. One end of the oil pipe is connected to the fuel tank through a hose clamp, and the other end is connected to the square pipe. The internal semi-closed state of the square pipe is used for the pressure balance between the fuel tank and the atmosphere, which can prevent dust from entering the fuel tank at the same time. Even if a small amount of oil foam is discharged into the square pipe, it can be stored in the bottom space and volatilized later to avoid oil stains falling on the chassis;

[0016] 3. Move the connection port of the oil pipe and the connecting pipe upward, so that more oil foam can flow back to the fuel tank. BRIEF DESCRIPTION OF THE DRAWINGS
