After the fixing bolts pass through the first fixing holes, they are fixedly connected to the chassis.

[0047] Specifically, in this embodiment, the surface of the mounting plate is perpendicular to the vertical fixing frame 2, that is, the vertical fixing frame 2 is installed vertically, which can better ensure the installation strength and installation stability.

[0048] In this embodiment, the connecting bracket 3 has a battery bracket mounting part 7 and a fuel tank bracket mounting part 10. The battery bracket mounting part 7 is fixedly connected to the fuel tank bracket, thereby fixing both the fuel tank and the battery on the central safety frame.

[0049] Specifically, in this embodiment, the battery bracket mounting part 7 consists of two vertically arranged angle steels with multiple mounting holes on its side wall. By engaging bolts with the mounting holes, the battery bracket can be fixedly installed.

[0050] More specifically, in this embodiment, the two angle steels are arranged symmetrically.

[0051] In this embodiment, the fuel tank bracket mounting part 10 is located between two angle steels, specifically, it is a plurality of second fixing holes on the connecting bracket 3. After the fixing bolt passes through the second fixing holes, it is fixedly connected to the fuel tank bracket, and the fuel tank is fixed on the connecting bracket 3 through the fuel tank bracket.

[0052] In a preferred embodiment, the base frame is further provided with a cover mounting section.

[0053] In this embodiment, after the hood mounting part is provided on the base frame, it can be fixedly connected to the hood of the tractor, thereby further increasing the stability of the central safety frame.

[0062] The setting of the limiting rubber pad 6 can effectively prevent the vibration of the crossbeam at the upper end of the safety frame, greatly improving the overall safety and stability.

[0063] In a preferred embodiment, the end of the vertical fixing frame 2 connected to the upper bracket 1 has a connecting mounting groove, and the upper bracket 1 is inserted into the connecting mounting groove; the limiting rubber pad 6 is disposed in the connecting mounting groove and is located on one side of the upper bracket 1.

[0064] In this embodiment, the upper end of the vertical fixing frame 2 is provided with an installation groove, and the end of the upper bracket 1 is inserted into the installation groove to be fixedly connected with the vertical fixing frame 2.

[0065] A limiting rubber pad 6 is installed in the mounting groove and is located on one side of the upper bracket 1. It can limit the upper bracket 1 and also reduce vibration, thereby improving the safety and stability of the whole machine.

[0066] In this embodiment, the limiting rubber pad 6 is cylindrical in shape.

[0067] It is understandable that the shape of the limiting rubber pad 6 can be cylindrical, or it can be other shapes, such as polygonal prisms, as long as it can limit and dampen the upper bracket 1.

[0068] In a preferred embodiment, the vertical fixing frame 2 has a wire harness fixing member at one end connected to the upper support 1 and on the side near the connecting support 3.

[0069] In this embodiment, the upper inner side of the vertical fixing frame 2 has a wire harness fixing component. By setting the wire harness fixing component, all wire harnesses passing through this position are fixed, thereby ensuring the smoothness of the line and facilitating maintenance.

[0071] In this embodiment, the wire harness fixing component is a wire harness fixing buckle.

[0072] In a preferred embodiment, the upper support 1 and the base frame are detachably connected.

[0073] In this embodiment, the upper support 1 and the base frame are detachably connected, which facilitates the installation and maintenance of the central safety frame.

[0074] In a preferred embodiment, the detachable connection is at least one of a pin connection, a bolt connection, and a snap-fit ​​connection.

[0075] In this embodiment, after the end of the upper bracket 1 is inserted into the mounting groove, the side wall of the mounting groove has bolt holes. The fixing bolt passes through the bolt holes and abuts against the side wall of the upper bracket 1 to achieve the purpose of fixing the upper bracket 1 in the mounting groove; or after the fixing bolt passes through the bolt holes, it is threadedly connected to the threaded hole on the side wall of the upper bracket 1 to achieve the fixed connection of the upper bracket 1.

[0076] It is understandable that the detachable connection method can be the bolt connection mentioned above, or it can be other fixed connection methods, such as snap-fit, pin connection, etc., or it can be a combination of multiple connection methods, such as a combination of pin connection and bolt connection, or a combination of snap-fit ​​and bolt connection, etc. In other words, as long as a detachable connection between the upper bracket 1 and the vertical fixed frame 2 can be achieved, it is acceptable.
