Generally, the washing nozzles are fixedly arranged at the head end or the tail end of the vehicle, and the installation height should not be too low to avoid being damaged by obstacles during walking. At the same time, such washing nozzles can achieve a relatively large spraying range, but the impact force of the sprayed water flow on the ground will be lost to a certain extent, and the cleaning effect on some stubborn stains on the ground is not particularly good; for some special scenarios, such as the interior of a workshop with chicken coops, there will inevitably be stains such as chicken manure and chicken feed on the aisle floor; these stains adhere to the workshop floor and will not be cleaned in time, but will be cleaned together when the chicken coops are washed; the chicken manure or chicken feed that has adhered to the floor for a long time has a very strong adhesion to the workshop floor, is not easy to be removed, and affects the sanitary environment in the workshop; conventional vehicles for washing can only sprinkle water on the ground, but it is difficult to remove these stains.

[0028] Embodiment 1: Refer to Figure 1-8, A trolley chassis with cleaning function includes a chassis frame 1 and four walking wheels. The chassis frame 1 is in an overall frame structure and serves as the main body of the trolley chassis. The four walking wheels are installed at the four corners of the bottom of the chassis frame 1, enabling the trolley to move. The trolley chassis further includes symmetrically arranged cleaning components. The cleaning components are used to clean the ground. The cleaning components are arranged below the middle of the chassis frame 1 and include an L-shaped pipe 31, a cleaning nozzle 32, a rotary joint 33, a pulling spring 34, and a locking mechanism. The L-shaped pipe 31 includes a pipe A 311 and a pipe B 312 that are connected and communicate with each other for circulating high-pressure water flow. The cleaning nozzle 32 is installed at the end of the pipe A 311. The rotary joint 33 is horizontally arranged and connected to the pipe B 312 to deflect the L-shaped pipe 31 vertically. The rotary joint 33 is connected to the chassis frame 1 to connect the high-pressure water flow. When the L-shaped pipe 31 is close to the vertical state, high-pressure water flow is introduced, causing the high-pressure water flow to be sprayed out through the cleaning nozzle 32 to clean the ground. When the L-shaped pipe 31 is close to the horizontal state, high-pressure water flow is no longer introduced. The cleaning nozzle 32 is retracted and lifted to avoid the possibility of being damaged by collision. One end of the pulling spring 34 is connected to one side of the L-shaped pipe 31, and the other end is connected to the chassis frame 1. The pulling spring 34 acts on the L-shaped pipe 31 to make the L-shaped pipe 31 have a state of changing from a state close to the vertical state to a state close to the horizontal state. The locking mechanism is arranged on the other side of the L-shaped pipe 31 to lock the L-shaped pipe 31 in a state close to the vertical state.
[0029] Compared with the prior art, the cleaning components of the present utility model can lock the L-shaped pipe 31 in a state close to the vertical state during use, introduce high-pressure water flow to wash the ground. The cleaning nozzle 32 has a relatively low height, and the impact force of the sprayed water flow has a relatively large impact force on the ground, with good flushing effect. When the cleaning components are not in use, the L-shaped pipe 31 is pulled by the pulling spring 34 to be close to the horizontal state and thus retracted to avoid bumping into obstacles.
[0030] The walking wheels include two driving wheels 21 and two driven wheels 22. The two driving wheels 21 are arranged on one side of the chassis frame 1. The two driven wheels 22 are arranged on the other side of the chassis frame 1. The driving wheels 21 are each equipped with a walking motor 211. The walking motor 211 outputs torque to drive the driving wheels 21 to rotate. The rotating driving wheels 21 act on the chassis frame 1 to move the chassis frame 1, and the driven wheels 22 follow.
[0031] The driven wheels 22 are universal wheels, enabling the trolley to make a certain turn.

At this time, the L-shaped pipe 31 is close to the vertical state; when the locking bolt 353 is loosened, the pin shaft 3531 is disengaged from the pin hole 3511; the pulling spring 34 acts on the L-shaped pipe 31, and at this time, the L-shaped pipe 31 is close to the horizontal state.
[0035] The swing plate 351 is inclined relative to the L-shaped pipe 31, so that after the L-shaped pipe 31 is locked, it is also inclined to the chassis frame 1.
[0036] The cleaning nozzle 32 is inclined relative to the pipe B 312 to facilitate the impact on the ground.
[0037] The locking mechanism further includes a seat plate 354 connected to the chassis frame 1; the connecting nut 352 is fixedly connected to the seat plate 354 to facilitate locking the swing plate 351 and further locking the L-shaped pipe 31.
[0038] The seat plate 354 is a bent plate, which is convenient for manufacturing. One end of the seat plate 354 is connected to the chassis frame 1, and the other end is provided with the connecting nut 352.
[0039] The seat plate 354 is provided with a through hole 3541 matching the locking bolt 353; the end face of the connecting nut 352 abuts against the seat plate 354, which can increase the connection area between the connecting nut 352 and the seat plate 354 and improve the connection strength; the locking bolt 353 passes through the through hole 3541 and is in threaded connection with the connecting nut 352.
[0040] The locking bolt 353 is provided with a step 3532 matching the through hole 3541; the step 3532 can limit the telescopic stroke of the pin shaft 3531.

[0042] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, and the same parts will not be described again. The difference is that: the swing plate 351 is connected to the end of the pipe B 312, thereby reducing the swing amplitude of the swing plate 351 and making the structure of the locking mechanism more compact.
