[0021] The present invention provides a sanitation vehicle that can automatically clean curbstones through improvement, and its working principle is as follows: First, the staff can first inject the cleaning liquid into the box body 1 through the liquid inlet 2, and then place the device parallel to the outside of the curbstone to be cleaned, and then under the operation of the driving body 7, the first roller 6 and the second roller 9 can be slowly moved along the curbstone, and the laser sensor 8 arranged at the lower end of the driving body 7 can sense obstacles in the driving direction (because the driving body 7 and the laser sensor 8 are both relatively mature technologies on the market, so they are not elaborated too much in this article), and the setting of the protective shell 5 and the protective cover 38 can play a good protective effect; Second, the staff can then use the external induction control switch to make the pump body 31 work, and the liquid extraction pipe 32 set at the right end of the pump body 31 can extract the water in the box body 1, and then the pump body 31 can transfer the water to the transmission hose 34 through the liquid outlet pipe 33, and finally the transmission hose 34 can spray the water from the nozzle 37. The multiple nozzles 37 set can clean a larger area on the curbstone; Third, in this process, the second motor 42 can drive the second rotating shaft 436 to rotate, so that the first rack 434 and the second rack 437 can mesh and rotate with the gear 435, so as to achieve the effect of the first rack 434 and the second rack 437 moving in different directions, and the first limiting rod 432 and the second limiting rod 439 are set to play the role of limiting auxiliary sliding, so as to orderly extend the cleaning brush 46 at the lower end of the fixed rod 45 from the movable door 48 inside the limiting groove 47, so as to clean the curbstone; Fourth, if the staff needs to adjust the angle of the nozzle 37, the first motor 362 can be rotated to rotate the first rotating shaft 363, and the screw 365 will drive the rotating wheel 366 to rotate in meshing, so that the housing 3671 can be rotated, and the connecting rod 3675 will also rotate in the protection area 35 to cooperate with the rotation, so as to adjust the angle of the nozzle 37 fixed at the lower end of the shunt pipe 3674, so as to achieve the effect of multi-angle spraying of the nozzle 37; Fifth, the connection groove 3672 disposed at the top of the connection pipe 3673 facilitates the connection of the transmission hose 34 to transport water, while the diversion pipe 3674 at the lower end of the connection pipe 3673 can divert the water.
