[0027] To make the technical solution, advantages, and objectives of this utility model clearer, the technical solution of the embodiments of this utility model will be clearly and completely described below. The described embodiments are some, but not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0028] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0029] like Figures 1-4 As shown, a railway ballast sweeper provided by this utility model includes a car body, a drive system, a sweeping system, and a support and guide transmission mechanism.

[0030] The vehicle body consists of a protective box 1 and a running mechanism 3. The protective box 1 is a cuboid structure with leather baffle shells 2 on all four sides. The bottom of the baffle shells 2 is trapezoidal and serrated, and is fixed to the four sides of the vehicle body to shield against ballast splashed in an accident. It can be removed at any time.

[0031] The cleaning system consists of a cleaning brush and a cleaning platform. The cleaning platform is composed of a first steel plate 5, a second steel plate 6, and a third steel plate 7 connected by bolts, and the cleaning platform is equipped with cleaning platform marking points 4.

[0032] The bolt first passes through the P-shaped shaft length hole and then connects to the first and second steel plates and is set on the top of the protective box 1. A plum blossom knob 8 is installed on the top of the bolt.

[0033] The railway ballast sweeper's sweeping platform uses segmented steel plates connected by bolts, which facilitates maintenance and replacement, improves operational efficiency and safety, and reduces weight to adapt to complex working conditions.

[0034] A battery compartment 19 is located on one side below the second steel plate 6 of the cleaning platform, and a pin chain 20 is located on the other side near the side wall connection. The pin chain 20 is fixed to the inside of the triangular support structure and is used to pin / lock the high-voltage bushing.

[0035] A battery cover 10 is provided above the battery compartment 19, and the battery cover 10 is located on one side of the top of the second steel plate 6 of the cleaning platform.

[0036] The second steel plate 6 of the cleaning platform is also provided with an inspection window 9 on one side of the top, and an inspection baffle 11 is provided on the inspection window 9.

[0037] The inspection window 9 is divided into two parts: one part is a recessed, semi-enclosed structure that shields the motor and is located directly above the connection point between the drive motor 17 and the transmission shaft 16; the other part is an open structure. This structure protects the motor from external interference and facilitates observation of its operating status. The open structure also provides maintenance personnel with direct access to critical components such as the motor, greatly facilitating daily inspection and maintenance.

[0038] Both the inspection baffle 11 and the battery cover 10 are provided with a number of round holes. These round holes not only help with ventilation and heat dissipation, keeping the internal temperature of the equipment at a suitable level, but also reduce the weight of the baffle, providing more operating space for maintenance personnel and making maintenance work more convenient and efficient.

[0039] The drive system includes a drive motor 17 and an eccentric seat 18. The drive motor 17 is located on one side below the sweeping platform and is connected to the drive shaft 16 via the eccentric seat 18. The drive shaft 16 drives the sweeping brush, composed of high-pressure support sleeves 12, to rotate. The high-pressure support sleeves 12 are evenly arranged longitudinally along the drive shaft, enabling the drive system to efficiently transmit power to the sweeping brush, driving it to rotate rapidly, thereby achieving efficient sweeping of railway ballast. Simultaneously, the optimized design of the drive system reduces energy consumption and improves overall operational efficiency.

[0040] The support and guide transmission mechanism consists of a support frame 13, guide wheels 15, guide wheels 14 of the ballast sweeper drive hub motor, high-pressure support sleeve 12, and drive shaft 16.

[0041] The support frame 13 is a triangular structure, located on both sides of the protective box 1 and connected to the second steel plate 6 of the sweeping platform, providing a solid support foundation for the entire ballast sweeper.

[0042] The support frame 13 has guide wheels 14 for the ballast sweeper drive hub motor installed on one side and the other side of the support frame 13. Guide wheels 15 are installed on the other side.

[0043] The guide wheels 14 and 15 of the ballast sweeper drive hub motor are equipped with support plates on both sides. The support plates are located at the connection between the guide wheels 14 and 15 of the ballast sweeper drive hub motor and the steel plate connecting the sweeping platform. This ensures that the ballast sweeper can maintain a stable posture and accurate guidance during operation, effectively avoiding deviation and shaking, and improving the accuracy and efficiency of sweeping operations.

[0044] The drive system and support guide transmission mechanism are located inside the protective housing 1. This layout significantly optimizes the overall structure, making it more compact and reducing space occupation. It also provides excellent protection for critical internal components, effectively resisting the corrosive effects of the external environment on the components, thereby extending the service life of the equipment.

[0045] Therefore, this utility model provides a railway ballast sweeper with an ingenious design, compact structure, and excellent protective performance, effectively protecting key internal components. The sweeping platform is rationally designed, with modular sections and bolted connections facilitating maintenance and greatly simplifying daily inspection and maintenance. The stable support and guiding transmission mechanism ensures stable operation and accurate guidance of the ballast sweeper. The efficient drive system, with optimized design of the drive motor and transmission shaft, improves sweeping efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
