[0036] The brush sheet 14 has dense and uniform bristles, and the bristles are made of a material with moderate hardness and good wear resistance to ensure a cleaning effect.

[0037] like Figure 2 The vehicle compartment cleaning machine shown in the figure comprises a vehicle body 2 arranged on the upper part of a vehicle body lower plate 1, a lifting frame 3 is fixedly mounted on the vehicle body 2, and a cab 4 is mounted on the upper part of the lifting frame 3 to expand the driver's field of vision.

[0038] A boom 5 and a boom cylinder 6 are also hinged to the upper part of the vehicle body 2, the other end of the boom cylinder 6 is hinged to the middle part of the boom 5, a dipper arm 8 is hinged to the end of the boom 5, a dipper arm cylinder 7 is hinged above the middle part of the boom 5, the other end of the dipper arm cylinder 7 is hinged to the upper end of the dipper arm 8, a cleaning brush cylinder 9 is also hinged to the dipper arm 8, and the lower end of the dipper arm 8 is hinged to one end of the ear plate bracket 12; a second connecting rod 11 is also hinged to the lower end of the dipper arm 8, and the other end of the cleaning brush cylinder 9 of the dipper arm 8 is hinged to the second connecting rod 11; it also includes a first connecting rod 10, the upper end of the first connecting rod 10 is hinged to the hinge point of the cleaning brush cylinder 9 and the second connecting rod 11, and the lower end of the first connecting rod 10 is hinged to the other end of the ear plate bracket 12, forming a stable linkage structure.

[0039] The lifting frame 3 includes a base, a folding portion is fixedly connected to the upper part of the base, and a connecting plate is hinged at the end of the folding portion; the folding portion includes a lower arm, a first upper arm and a second upper arm, the upper end of the lower arm is hinged to the head end of the first upper arm and the second upper arm, the first upper arm and the second upper arm are parallel to each other, double ear plates are arranged on both sides of the connecting plate, the tail ends of the first upper arm and the second upper arm are hinged to the double ear plates, and a fixing plate is arranged between the two second upper arms;

[0040] The lower arm is a frame structure with side panels 13 on both sides, which are connected and fixed by horizontal steel plates to form a trough body. A steel frame structure is arranged in the trough body, which plays a reinforcing function on the one hand, and plays a certain supporting role when the cab 4 is lowered to the initial position on the other hand.

[0041] When the folding portion is in a folded state, the first upper arm and the second upper arm are both located in the slot of the lower arm, which can save space and make the force-bearing structure more reasonable, thereby improving the load-bearing capacity.

[0042] It also includes two oil cylinders parallel to each other, both of which are located between the two lower arms, the lower ends of the oil cylinders are hinged to the lower ear plates on the base, and the upper ends of the oil cylinders are hinged to the upper ear plates on the fixed plate;

[0048] The safety pin ear plate is hinged to the lower arm through the safety pin to form a stable triangular structure. When the cab 4 is raised, the mechanical force generated by the cab 4's own weight is transferred from the cylinder to the triangular structure composed of the safety pin and the safety pin ear plate, thereby ensuring the service life of the cylinder, effectively preventing damage to the cylinder, and avoiding sudden falling of the cab 4 due to damage to the cylinder.

[0049] When the cylinder extends, the folding part will rise; when the cylinder shortens, the folding part will fall.

[0050] A connecting column for improving structural strength is arranged between the two first upper arms.

[0051] A reinforcement portion is arranged between the upper ends of the two lower arms. The reinforcement portion includes a transversely arranged steel pipe and a vertically arranged steel plate. The steel plate also serves a shielding effect.

When the folding portion is in the folded state, the first upper arm and the second upper arm are parallel to the upper section of the lower arm.

[0053] The connecting plate is connected to the lower part of the rear part of the cab 4. After the folding part is completely lowered and folded, the lower surface of the cab 4 just falls to a position at the same height as the base.

[0054] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.
