Example 2:

in embodiment 1, the water in the spray pipe 44 and the cleaning agent are introduced through the water supply mechanism 5, in the prior art, the cleaning water is generally introduced into the spray pipe 44 through the water pump, however, because the water led out by the water pump is continuous, the spray pipe 44 always sprays water on the carriage, and the cleaning of the rolling brush 37 does not need to always supply water, which leads to serious waste of water resources;

referring to fig. 1 to 7, as another preferred embodiment of the present invention, the water supply mechanism 5 is different from embodiment 1 in that it includes a cylinder 51, a piston assembly 52, a first check valve 53, a second check valve 54, a slide bar 55, a toothed plate 56, a first motor 57, an incomplete gear 58, and a second spring 59; the cylinder 51 is fixedly arranged on the outer side of the storage box 41, the first one-way valve 53 is fixedly arranged at the inlet end of the cylinder 51, and the inlet end of the first one-way valve 53 is communicated with the outlet end of the converging pipe 46; the second one-way valve 54 is fixedly arranged at the outlet end of the cylinder 51, and the outlet end of the second one-way valve 54 is communicated with the spray pipe 44 through a conduit; the slide bar 55 runs through the top wall of the cylinder 51 and is in sliding connection with the cylinder 51, the bottom end of the slide bar 55 is connected with the piston assembly 52, the top end of the slide bar 55 is fixedly connected with the toothed plate 56, the first motor 57 is fixedly arranged outside the storage box 41, the incomplete gear 58 is fixedly arranged on the output shaft of the first motor 57 and can be meshed with the toothed plate 56, and the second spring 59 is sleeved on the slide bar 55 and is positioned inside the cylinder 51.

Working principle: firstly, two rolling brushes 37 on a mounting frame 31 are fully attached to a carriage by controlling a running gear 2, a first motor 57 is started to enable an incomplete gear 58 to rotate, when the incomplete gear 58 is meshed with a toothed plate 56, the toothed plate 56 drives a sliding rod 55 to move upwards, meanwhile, the sliding rod 55 drives a piston assembly 52 to move upwards, a second spring 59 is extruded to store elastic potential energy, the pressure inside a cylinder 51 is reduced, and therefore a cleaning agent and water are led into the cylinder 51 by a first one-way valve 53;

when the incomplete gear 58 is separated from the toothed plate 56, the second spring 59 releases elastic potential energy, so that the piston assembly 52 moves downwards, the pressure inside the cylinder 51 is increased, the second one-way valve 54 guides out cleaning agent and water inside the cylinder 51, and finally the cleaning agent and water are sprayed onto a carriage through the spray head 45, and the electromagnetic valve 47 can control the flow rate of the cleaning agent; intermittent engagement of the incomplete gear 58 and the toothed plate 56 enables the piston assembly 52 to move up and down, and further enables the spray head 45 to realize intermittent water spraying, so that water resources are greatly saved, and the use cost is reduced;

simultaneously, the double-shaft motor 361 is started to enable the two universal couplings 362 to rotate synchronously, so that the two rotating shafts 363 drive the corresponding first bevel gears 364 to rotate synchronously, the two second bevel gears 365 rotate synchronously, and as the two first bevel gears 364 are symmetrically distributed, the rotating directions of the two second bevel gears 365 are opposite, the two rolling brushes 37 can rotate oppositely, and dirt on a carriage can be thrown outwards.

Example 3:

in embodiment 2, the water supply mechanism 5 realizes intermittent water supply, but, because the water volume introduced in a single period inside the cylinder 51 is constant, the water pressure of the water led out by the second one-way valve 54 is constant, the water pressure sprayed by the spray pipe 44 cannot be adjusted, and the spray pipe 44 cannot meet the actual spraying requirement;

referring to fig. 1 to 8, as another preferred embodiment of the present invention, the difference from embodiment 1 or embodiment 2 is that the piston assembly 52 includes a second motor 521, a gear 522, and an adjustment member 523; the second motor 521 is fixedly installed at the outer side of the storage tank 41, the gear 522 is fixedly installed on the output shaft of the second motor 521, and the adjusting member 523 is installed on the cylinder 51 and can be matched with the adjusting member 523;

when the incomplete gear 58 is separated from the toothed plate 56, the second spring 59 releases elastic potential energy, so that the piston assembly 52 moves downwards, the pressure inside the cylinder 51 is increased, the second one-way valve 54 guides out cleaning agent and water inside the cylinder 51, and finally the cleaning agent and water are sprayed onto a carriage through the spray head 45, and the electromagnetic valve 47 can control the flow rate of the cleaning agent; intermittent engagement of the incomplete gear 58 with the toothed plate 56 also enables the piston assembly 52 to move up and down, thereby enabling intermittent water spraying by the spray head 45;

simultaneously, the double-shaft motor 361 is started to enable the two universal couplings 362 to rotate synchronously, so that the two rotating shafts 363 drive the corresponding first bevel gears 364 to rotate synchronously, the two second bevel gears 365 rotate synchronously, and as the two first bevel gears 364 are symmetrically distributed, the rotation directions of the two second bevel gears 365 are opposite, the two rolling brushes 37 can rotate in opposite directions, and dirt on a carriage can be thrown outwards;

when the injection pressure of the spray head 45 needs to be changed, the second motor 521 is started to rotate the gear 522, so that the outer gear ring 5238 and the rotary drum 5236 rotate, the inner gear sleeve 5237 rotates synchronously, all the gear rings 5235 drive the corresponding inner thread sleeves 5234 to rotate, the corresponding screw rods 5233 and the corresponding inner thread sleeves 5234 displace relatively, the piston 5232 approaches or moves away from the mounting plate 5231, the distance between the piston 5232 and the mounting plate 5231 is adjusted, and the water volume introduced in a single period of the cylinder 51 is changed; and thus the water pressure of the water led out from the cylinder 51 is changed, and thus the adjustment of the water pressure sprayed from the spray pipe 44 is realized.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
