two small wheels 45 which are arranged in parallel are respectively positioned above the two big wheels 44, and both the two small wheels 45 are abutted against the upper part of the main pipeline 33 to clamp the main pipeline 33 between the two small wheels 45 and the two big wheels 44; the two small wheels 45 can be connected above the machine body 40 in an up-and-down mode through the small wheel support body 451, and an accommodating space is reserved between the top of the small wheel support body 451 and the top of the machine body 40; the top of the small wheel support 451 is connected with a movable rod 452, the movable rod 452 can be vertically moved and arranged in a movable hole 453 of the machine body, a pressing spring 454 is sleeved on the movable rod 452, the movable rod 452 is in threaded connection with a pressing nut 455, and the pressing spring 454 is positioned above the pressing nut 455; the small wheel 45 is rotatably connected in a small wheel support 451.

In this way, the reducer 42 with the servo motor 41 drives the transmission gear to rotate, so as to drive the bull wheel transmission gear I and the bull wheel transmission gear II to rotate, so that the rotation of the two bull wheels is realized, the main pipeline is driven to be pushed forward, the main pipeline is clamped through the two bull wheels and the two small wheels, pressing force is applied to the main pipeline through the pressing spring, and the pressing force of the spring is adjusted through the pressing nut; the small wheel is inserted into a movable hole of the machine body through a movable rod and can move up and down, a pressing spring arranged on the small wheel provides pressing force, the pressing force can be adjusted through a pressing nut, and the small wheel does not have a power device and can rotate freely.

In the above technical solution, the tank cleaning unit 5 includes:

a support bar 50 having one end connected to a three-dimensional rotating high-pressure nozzle 51 and the other end connected to a driving unit 52, wherein the driving unit 52 drives the three-dimensional rotating high-pressure nozzle 51 to rotate; the water outlet pipeline of the high-pressure plunger pump 2 is connected with the water inlet of the three-dimensional rotating high-pressure nozzle 51 through a water supply hose and a water supply pipe arranged on the support rod 50;

a sealing barrel 53 disposed in the concrete pit 54 or outside the concrete pit 54, wherein the lower ends of the driving unit 52 and the support rod 50 are disposed in the sealing barrel 53, sealing caps 55 are disposed at both ends of the sealing barrel 53, and the upper ends of the three-dimensional rotating high-pressure nozzle 51 and the support rod 50 are disposed outside the sealing barrel 53; a sealing rubber pad is arranged between the sealing cover 55 and the sealing barrel 53; a water pipe and an electric wire inlet 56 are arranged on the sealing barrel 53; and the flange covers of the water pipe and the electric wire inlet are filled with epoxy resin after the water pipe and the electric wire are arranged; a water pipe and electric wire inlet 57 is formed in the concrete pit 54, and the water pipe and electric wire inlet is filled with epoxy resin after the water pipe and the electric wire are arranged; wherein, the joint of the support rod 50 and the sealing cover 55 is hermetically connected by a sealing rubber pad.

In the technical scheme, the cleaning structure of the tank cleaning unit is a structure commonly adopted in the prior art, such as the structure disclosed in a rotary spray head device of a CN201620263397.8 sprayer; the driving unit and the supporting rod are arranged in the concrete pit, and only the upper parts of the three-dimensional rotating high-pressure spray head and the supporting rod extend out of the ground, so that the box body to be cleaned can be placed on the ground to be cleaned, and the cleaning is convenient and fast.

In order to prevent water from accumulating in the concrete pit, a driving unit of the three-dimensional rotating high-pressure nozzle is sealed by a sealing barrel and sealing covers, all the sealing covers are sealed by rubber sealing gaskets, and flange covers of water pipes and electric wires are filled with epoxy resin after the water pipes and the electric wires are arranged, so that sealing is realized;

when the height of the box body to be cleaned is higher, and the height of the supporting rod and the three-dimensional rotating high-pressure sprayer is not enough to clean the higher box body, the sealing barrel is placed outside the concrete pit, so that the height of the supporting rod and the three-dimensional rotating high-pressure sprayer is increased, and the cleaning effect is improved.
