Description

Technical Field

[0001] The utility model belongs to the technical field of bulldozers, and in particular relates to a urea tank mounting structure for a bulldozer. Background Art

[0002] With the continuous improvement of national environmental protection policies, non-road vehicles have entered the National IV emission standard. To meet the new National IV regulations, exhaust treatment equipment must be installed at the rear end of the engine exhaust. This requires the entire machine to be equipped with urea for chemical reaction. Due to the compact internal structure of bulldozers, the urea tank is generally installed at the rear of the machine, together with the fuel tank. To improve the appearance, the outer protective shell of the urea tank is integrated with the fuel tank, leaving only a single opening for urea refilling.

[0003] Currently, there are two main urea filling port structures in the industry: one with a small door built into the protective shell at the urea tank filling port, and the other with a circular hole in the protective shell with a protective plate welded on top. Neither structure allows the urea tank to be removed independently. When the urea tank malfunctions and requires repair, the fuel tank must be removed before the urea tank can be removed. The former requires opening the small door at the urea tank filling port and then opening the urea tank lid to fill urea. Since the filling port is located inside, adding urea is more difficult. The latter has a gap between the urea filling port and the protective shell, allowing external dust and rainwater to easily enter. Utility Model Content

[0004] In order to solve the technical problem in the background art that the urea tank in the bulldozer is inconvenient to remove after installation, the purpose of the utility model is to provide a bulldozer urea tank installation structure that can solve the above problem.

[0005] The technical solution for achieving the purpose of the utility model is: a bulldozer urea tank mounting structure, comprising a urea tank and a mounting cover plate, a mounting cavity being provided on the bulldozer fuel tank, the urea tank being mounted in the mounting cavity, the mounting cover plate being mounted at the opening of the mounting cavity for sealing the mounting cavity; an opening being provided on the mounting cover plate, the urea tank having a urea tank filling port, the urea tank filling port extending to the opening.

[0006] In this solution, a mounting cavity is provided on the bulldozer fuel tank, and the urea tank is installed within the mounting cavity. The mounting cover is then fixed to the open opening to seal it, achieving the purpose of installing the urea tank and facilitating assembly and disassembly. When the urea tank needs to be removed, the mounting cover can be removed. This is simple and convenient, eliminating the traditional trouble of removing the fuel tank to remove the urea tank when the urea tank malfunctions and needs repair. The mounting cover is also provided with an opening, and the urea tank filling port on the urea tank extends into the opening, facilitating urea filling. The urea tank filling port extends through the opening to limit the urea tank, preventing it from shaking due to its unstable position within the mounting cavity. Furthermore, straps can be used in the mounting cavity to limit and secure the urea tank. This device has a simple structure and facilitates assembly and disassembly of the urea tank within the bulldozer fuel tank.

[0007] Furthermore, an open mounting head is included, the open mounting head being mounted in the opening, the open mounting head having an opening, and the urea tank filling port passing through the opening. In order to better limit the installation of the urea tank filling port, an open mounting head is added, and the urea tank filling port is mounted in the opening of the open mounting head.

[0008] Furthermore, the open mounting head protrudes toward the side where the urea tank is located to form a protrusion, and the opening is provided on the protrusion. In other words, one end of the open mounting head protrudes into the mounting cavity, leaving space for the opening, similar to the style of a fuel tank filler port on a car.

[0009] Furthermore, the mounting cover is provided with a waist-shaped mounting hole, and the open mounting head has a bolt hole corresponding to the waist-shaped mounting hole. The open mounting head is fixed to the mounting cover through the combination of the bolt hole, the waist-shaped mounting hole, and the mounting bolt. First, the mounting cover and the open mounting head are fixed by the mounting bolts, which facilitates installation and removal. Second, the waist-shaped mounting hole makes it easier to install and use when the open mounting head and the mounting cover do not match or are installed out of position, because the waist-shaped mounting hole is long and narrow, which improves installation efficiency.

[0010] Furthermore, the opening mounting head has an outwardly extending flange, which is mounted on the side of the mounting cover plate away from the urea tank and covers the opening, and the bolt holes are provided on the flange. In other words, the flange is larger than the opening, so that the flange can seal the opening on the outside of the mounting cover plate, preventing water and debris from entering the gap if the seal is not tight.

[0011] Furthermore, it also includes a guard ring, which is installed in the opening and is used to seal the gap between the urea tank filling port and the opening to prevent water and debris from entering when there is a gap, and also to avoid the problem of the urea tank filling port shaking in the opening.

[0012] Furthermore, the retaining ring is made of rubber, which is relatively soft, wear-resistant, and has a tighter seal.

[0013] Furthermore, the mounting cover is fixed to the bulldozer fuel tank by bolts, which facilitates installation and disassembly.

[0014] By adopting the above technical solution, the utility model has the following beneficial effects:

[0015] (1) A mounting cavity is provided on the bulldozer fuel tank, a urea tank is installed in the mounting cavity, and a mounting cover is used for sealing, so as to facilitate the disassembly and assembly of the urea tank. The mounting cover has an opening for the urea tank filling port to pass through and fill the urea tank with urea;

[0016] (2) In order to better limit the urea tank filling port, an open mounting head is added, and the urea tank filling port passes through the opening on the open mounting head;

[0017] (3) The mounting cover is provided with waist-shaped mounting holes corresponding to the bolt holes on the open mounting head, thereby improving installation efficiency and adaptability;

[0018] (4) The opening mounting head has a convex edge extending outward, which facilitates the sealing of the opening to prevent water and debris from entering;

[0019] (5) Add a rubber protective ring in the opening to improve the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

In this solution, a mounting cavity 4 is provided on the bulldozer fuel tank 3, the urea tank 1 is mounted in the mounting cavity 4, and the mounting cover 2 is fixed to the opening 5 for sealing. This achieves the purpose of mounting the urea tank 1 and facilitating assembly and disassembly. When the urea tank 1 needs to be removed, the urea tank 1 can be removed by simply removing the mounting cover 2. This is simple and convenient, and avoids the traditional trouble of removing the fuel tank before removing the urea tank 1 when the urea tank 1 malfunctions and needs to be repaired. The mounting cover 2 is provided with an opening 6, and a urea tank filling port 7 on the urea tank 1 extends to this opening 6, facilitating urea filling. Extending through the opening 6, the urea tank filling port 7 also serves to position the urea tank 1, preventing it from moving within the mounting cavity 4. Furthermore, straps can be used within the mounting cavity 4 to position and secure the urea tank 1. This device has a simple structure and facilitates the installation and removal of the urea tank 1 within the bulldozer's fuel tank 3.

[0026] Preferably, it further includes an open mounting head 8, which is installed in the opening 6.
