[0030] Embodiment 1 of the present utility model is as follows:

[0031] The railway ballast cleaning brush for excavators is a device specially designed for railway ballast cleaning. It can quickly remove the ballast on the sleepers 15 and improve the safety of railway operation. The brush body adopts high-strength hydraulic hose, which is wear-resistant and corrosion-resistant. The transmission system adopts gear transmission to ensure stable power transmission.

[0032] like Figure 1 As shown, it is a railway ballast cleaning brush specially used for railways. The top of the upper bracket 1 is connected to the excavator through a pin shaft, and the lower part is connected to the rotary motor 2 through bolts. The rotary motor 2 is connected to the connecting seat 3 through bolts. The lower bracket is driven to rotate by the hydraulic system of the excavator and can be adjusted according to different working conditions.

[0033] A fixing seat 5 is welded on the top of both sides of the lower bracket, and a rotating motor 6 is fixedly connected to the fixing seat 5, which is connected to the driven gears 9 at both ends of the brush rod 10 at the bottom of the lower bracket through the meshing chain of the driving gear 7. The hydraulic system of the excavator drives the rotating motor 6 to drive the driving gear 7 to rotate, and drives the driven gear 9 to rotate through the chain transmission, and the brush rod 10 rotates accordingly.

[0034] A fixing seat 5 is welded on the brush rod 10, and a high-strength, wear-resistant and corrosion-resistant rubber tube 11 is connected through the fixing seat 5. The hardness of the rubber tube 11 is moderate and will not cause damage to the surface of the roadbed. The wall of the rubber tube 11 contains steel wire, and the bottom is fastened to the fixing seat 5 by a pipe clamp to ensure that it will not fall off, wear or break easily in a harsh working environment, and can maintain a long service life.

[0035] The rubber tubes 11 are arranged in an interlaced manner to clean a wider range. Six rubber tubes 11 are arranged on the same circumferential surface, and the six rubber tubes 11 form a 60-degree angle with each other. The rubber tubes 11 on adjacent circumferential surfaces form a 30-degree angle, which can clean ballast without dead angles.

[0036] At the same time, protective shells 8 are assembled on both sides of the lower bracket, and there are oiling holes on the upper part for filling chain lubricating oil to ensure smooth chain transmission.

[0037] There is a set of bearings on each side of the brush rod 10, and there is a refueling hole under the bearing seat for normal maintenance and refueling.

[0038] The transmission structure adopts a double-motor chain structure on both sides, and the synchronous rotation torque is larger and more stable. No rubber tube 11 is installed at the rail position to prevent damage to the rail, which is more reasonable. The fixed seat 5 is a two-layer structure. The lower plate is connected to the lower bracket, and the upper and lower plates are connected by four bolts. The distance between the upper and lower plates can be adjusted by rotating the bolts, thereby adjusting the tightness of the chain, which is used to tighten the chain when the chain is stretched.

[0039] The lower support assembly also includes a guard plate 4, which can prevent the ballast thrown out by high-speed rotation from splashing.

[0040] Four new guide wheels 12 are added, a fixing plate is welded under the lower bracket, a bushing is embedded inside the guide wheel 12, a pin is used to connect the fixing plate and the guide wheel 12 in series, a refueling port is provided at the center of the pin, an oil channel is processed inside, oil seals are installed on both sides, and the tail is fastened with anti-drop bolts.

[0041] The fixed position of the guide wheel 12 is in accordance with the domestic 1435mm track.

[0042] The lower bracket includes a rib plate 13, which is an arc-shaped plate structure. There are 4 groups of rib plates 13 in total to improve the overall strength. At the same time, the fixed plate is located at the lower end of the two outer groups of rib plates 13 to ensure that when the guide wheel 12 contacts the rail 16, its reaction force is transmitted to the rib plate 13 and does not directly act on the guard plate 4.

[0043] During operation, the railway ballast cleaning brush can be placed directly on the track, and the excavator can be pushed forward to prevent damage to the track due to misoperation.

[0044] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
