Technical Field

[0001] The utility model belongs to the technical field of screen cleaning machines, in particular to an adjusting device of a railway ballast screen cleaning machine. Background Art

[0002] Railway ballast cleaning machines are essential equipment for railway maintenance. Their main function is to clean the ballast beneath the railway tracks, which is the layer of crushed stone or pebbles. This layer is crucial to the stability of the railway and the smooth operation of trains.

[0003] Traditional railway ballast cleaning and screening machines typically consist of a complex series of mechanical structures, such as a cutterhead, chain drive system, and screening device, which work together to effectively remove impurities from the ballast and redistribute the ballast to maintain a clean and stable surface beneath the track. However, in practical applications, these mechanical structures often face various challenges, such as terrain variations, differences in ballast hardness and composition, and maintenance costs.

[0004] The adjustment devices of traditional railway ballast cleaning and screening machines may have certain limitations. For example, the connection between the cutterhead cross frame and the sprocket frame may not be flexible enough to adapt to changes in different terrain and ballast conditions; the transmission mechanism may wear out due to long-term operation, resulting in reduced efficiency or frequent failures; in addition, the lack of an effective discharge mechanism for the fine particles and impurities generated during the cleaning and screening process may affect the normal operation of the equipment and the surrounding environment. Summary of the Invention

[0007] By adopting the above technical solution, the basic structure provides a stable and adjustable transmission device for the railway ballast screening machine. The cutter disc cross frame serves as the supporting structure, and the sprocket frame is connected to the cutter disc cross frame through the transmission mechanism, realizing the power transmission and drive of the cutter disc.

[0009] By adopting the above technical solution, the mounting groove facilitates the installation of the adjusting screw member and the mounting plate, while ensuring the compactness and stability of the entire adjusting device. The setting of the through hole and the cover plate provides a channel for adjusting the adjusting screw member, and can close the through hole when adjustment is not required to prevent impurities from entering.

[0010] Optionally, a slag discharge hole is formed at one end of the mounting groove away from the through hole, and the slag discharge hole is connected to the position of the through hole.

[0011] By adopting the above technical solution and setting the slag discharge holes, the fine particles and impurities generated during the screening process can be discharged smoothly, avoiding accumulation and blockage inside the equipment.

[0012] Optionally, a through hole is provided on the surface of the mounting plate for movement of the adjusting screw member.

[0013] By adopting the above technical solution, the perforation provides a channel for the movement of the adjusting screw member, so that the adjusting screw member can move smoothly on the mounting plate, thereby achieving the distance adjustment between the cutter disc horizontal frame and the sprocket frame.

[0014] Optionally, the adjusting screw member includes a threaded rod and a connecting column connected to the threaded rod, the diameter of the connecting column is larger than the diameter of the threaded rod, the connecting column is flat at one end away from the threaded rod, and a docking hole is provided on the connecting column.

[0015] By adopting the above technical solution, the structural design of the adjusting screw member is reasonable. The threaded rod is used to cooperate with the locking nut to realize the adjustment function, and the connecting column is used to connect with the connecting seat to transmit the adjustment force. The setting of one end of the flat connecting column and the docking hole facilitates the connection and fixation of the connecting seat and the adjusting screw member.

[0016] Optionally, a pair of the locking nuts are respectively provided with rotation grooves on their surfaces, the number of the rotation grooves is several, and the several rotation grooves are distributed on the outer circumference of the locking nut in an upper and lower staggered manner.

[0017] By adopting the above technical solution, the setting of the rotation groove provides convenience for the adjustment of the locking nut, allowing the operator to easily rotate the locking nut through the tool, and the upper and lower staggered distribution method improves the convenience and efficiency of the adjustment operation.

[0019] By adopting the above technical solution, the connection between the connecting seat and the adjusting screw member is stable and reliable. The setting of the ear plate, connecting hole and connecting pin ensures the firm connection between the connecting seat and the adjusting screw member. At the same time, the setting of the connecting pin also enables the connecting seat to slightly adjust the angle when adjusting the spacing, ensuring the smoothness of the adjustment.

[0021] 1. By providing a mounting slot on the cutter disc frame and providing an adjustable adjustment screw, this device achieves adjustment of the spacing between the cutter disc frame and the sprocket frame. This design allows the operator to optimize the tension of the transmission mechanism according to actual needs, avoiding problems such as poor meshing, tooth jumping, and chain derailment caused by insufficient or excessive chain tension. Appropriate tension can also reduce vibration and noise during the transmission process, improving the operating smoothness of the entire machine. 2. The locking nut design on the adjustment screw ensures stability after adjustment. The locking nut can effectively prevent the adjusting screw from loosening under vibration or impact, thereby protecting the transmission mechanism from damage. In addition, the flat design of the connecting seat and the connecting column and the docking hole connection further enhance the stability and durability of the structure. At the same time, the sprocket frame can be slightly adjusted at an angle. These designs enable the transmission mechanism to maintain high efficiency and stable operation for a long time, thereby extending the service life of the equipment; 3. The slag discharge hole design on the side wall of the mounting groove provides an effective discharge channel for fine particles and impurities generated during the screening process. This design not only avoids the accumulation and blockage of impurities inside the equipment, but also reduces the impact of impurities on the locking nut and the adjusting screw. At the same time, the design of the protective plate also protects the sprocket frame and the transmission mechanism, preventing impurities from damaging them. BRIEF DESCRIPTION OF THE DRAWINGS
