The rolling brush device 36 located in the front of the driving direction rotates anticlockwise, the rolling brush device 36 located in the rear of the driving direction rotates clockwise, and the rolling brush device brush pollutants on the surface of the track bed through the central brush 39 to collect the track bed pollutants to the air suction duct 34. The side brush 45 is rotated by the operation of the side hydraulic motor 44 of the side brush roll 26. Meanwhile, the side lifting hydraulic cylinder 42 operates to lower the entire side brush rolling brush 26 along the lifting guide cylinder 43 to an operating state, i.e., the side brush 45 contacts the track bed surface, and a certain amount of pressing hair exists. The hydraulic rod of the side lifting hydraulic cylinder 42 has the length-adjustable function, and when the hair pressing amount of the side hair brush 45 and the ballast bed is lower than the operation range value after operation for a period of time, the hair pressing amount is adjusted by adjusting the length of the hydraulic rod of the hydraulic cylinder, so that the operation requirement is met.

The track bed pollutant is brushed by the brush roller and enters the storage bin device 24 through the vacuum sewage suction pipe 27 according to the negative pressure dilute phase conveying principle, the pollutant is blocked by the isolation grid 29 and is influenced by the gravity of the pollutant, the pollutant with large particle size drops into the storage trolley 28, and the pollutant with small particle size drops into the storage bin device 24 through the blocking of the filter screen 30. The pollutants enter the vacuum filter 23, are blocked in the vacuum filter by high-efficiency vacuum filtration, and the wind meeting the environmental standard is discharged to the atmosphere through the vacuum fan 22.

Wherein, the filter screen of the vacuum filter device 23 adopts a square-shaped structure arrangement, which can increase the filter area to a limited extent. The storage trolleys 28 are respectively arranged on two sides of the vehicle, a lateral discharging mode is adopted, filter holes are arranged below the storage trolleys 28, absorbed water can be effectively filtered into the storage bin device 24, and large-particle-size pollutants are remained in the storage trolleys 28.

Wherein the central brush roller 25 brush is provided with 3 aspiration channels with the diameter of 200mm, and an integral rectangular aspiration channel is arranged below the aspiration channels. The outside of the central brush rolling brush is provided with a protective cover 35 which plays a role in protecting the rolling brush device 36 and forming a semi-closed environment, so that the sewage suction effect is improved.

Wherein the side brush rolls 26 and respectively sets up one in vehicle both sides, and the side brush rolls and is provided with 1 aspiration channel of diameter 200mm, and the aspiration channel falls into two wind channels 46 of induced drafting, arranges respectively in the both sides of brush 45, all can the soil pick-up when satisfying the two-way operation of operation car.

The vacuum sewage suction system utilizes a negative pressure dilute phase conveying principle, generates air flow and negative pressure through a fan, acts on the tail end of the brush rolling brush device through a vacuum pipeline, and carries out adsorption recovery on the ballast bed pollutants stripped and washed by the high-pressure water jet. Meanwhile, the brush rolling brush device is provided with the rolling brush, and the rotating and rolling brush disturbs the pollutants on the track bed to generate kinetic energy, so that vacuum adsorption is facilitated. The electromagnetic adsorption system utilizes the electromagnetic adsorption principle to adsorb and collect large scrap iron hardening objects falling off during rail grinding in the ballast bed area. The electromagnetic adsorption type adopts an automatic iron unloading type.

The soil pick-up structure includes brush mechanism and soil pick-up pipe, storage silo, filter equipment and the fan that communicates in proper order, and brush mechanism passes through elevating system and connects the automobile body, and brush mechanism outside is covered with the protection casing, and soil pick-up pipe intercommunication protection casing is as soil pick-up structure input for absorb the filth that brush mechanism swept and carry to the storage silo.

The brush mechanism comprises a central brush and side brushes, the central brush is arranged between the corresponding rails, the side brushes are arranged outside the corresponding rails, and the central brush and the side brushes are respectively matched with a protective cover.

The electromagnetic adsorption system includes an adsorption structure, and the adsorption structure in the railroad track bed adsorption device in example 1 may be used.

The integral cleaning system adopts the operation processes of water jet stripping, vacuum dirt absorption and electromagnetic adsorption, adopts high-pressure water and air as transmission media, can effectively clean the pollutants in the ballast bed, and in addition, the high-pressure water has the dust suppression function, thereby avoiding secondary pollution; adopt the electromagnetism to adsorb the function on the one hand, adsorb the collection to the bold iron fillings thing that leaves over behind the rail is polished, on the other hand adopts vacuum suction railway roadbed filth, clears up other non-ferromagnetic little volume filths.

The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure, and various modifications and changes may be made to the present disclosure by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present disclosure should be included in the protection scope of the present disclosure.
