DETAILED DESCRIPTION

[0017] In order to better understand the purpose, structure and function of the present invention, a multifunctional railway screening machine of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] Please refer to the attached Figures 1 to 6 A multifunctional railway screening machine according to some embodiments of the present invention is described.

[0019] like Figures 1 to 6 As shown, a multifunctional railway cleaning machine of the present invention comprises a cleaning machine body consisting of a chassis 1, a power device 2, a crawler 3, a large arm 4 and a small arm 5. Specifically, the power device 2 is arranged on the chassis 1, the crawler 3 is arranged on the power device 2, and the large arm 4 and the small arm 5 are also arranged on the chassis 1. During construction, the power device 2 is started to drive the crawler 3 to rotate, and the cleaning machine body can be driven to travel on the rails and move on the rails.

[0020] The forearm 5 and the arm 4 are both provided with hydraulic cylinders. A connecting plate 6 is rotatably provided on the forearm 5. The connecting plate 6 is rotatably connected to the hydraulic cylinder on the forearm 5 and the connecting plate 6. The horizontal angle of the connecting plate 6 can be controlled by the hydraulic cylinder on the forearm 5 and the arm. The connecting plate 6 is also provided with rake teeth 7 for cleaning out the ballast stones (gravel and pebbles) under the sleepers. When the rake teeth 7 are started, the rake teeth 7 can be extended under the sleepers through the coordinated driving of the arm 4 and the forearm 5, and the rake teeth 7 can clean out the ballast stones under the sleepers. A through opening 61 is provided on the side of the connecting plate 6 relative to the rake teeth 7. The through opening 61 is provided with a conveying part 8. The conveying part 8 can clean the ballast stones cleaned out by the rake teeth 7 to the side of the rails to prevent the rake teeth 7 from colliding with the ballast stones accumulated in the traveling direction, thereby affecting the cleaning efficiency of the cleaning machine body driving the rake teeth 7 to the roadbed.

[0021] The conveying part 8 can be arranged on the connecting plate 6 in a direction relative to the rake teeth 7, such as Figure 3 and Figure 4 As shown, the conveying part 8 includes a first guard plate 81 and a second guard plate 82 which are arranged oppositely on the inner wall of the passage 61, and sprockets 83 are rotatably arranged at both ends of the first guard plate 81 and the second slide plate, and a conveying chain 84 is meshed on the two sprockets 83, and a push plate 85 is distributed on the conveying chain. A driving mechanism 86 is arranged outside the second guard plate 82, and the driving mechanism 86 is connected to the sprocket 83 arranged corresponding to it. After the rake teeth 7 clean out the ballast stones under the sleeper, they will fall onto the conveying chain 84, and then the driving mechanism 86 drives the sprocket 83 connected thereto to rotate, and the other sprocket 83 is synchronously rotated with the sprocket 83 connected to the driving mechanism 86 under the action of the conveying sprocket 83, and the conveying sprocket 83 drives the ballast stones on it to be transported to one side, thereby reducing the accumulation of ballast stones cleaned out by the rake teeth 7 and improving the cleaning efficiency of the cleaning machine. It should be noted that the driving mechanism 86 can be an electric motor, etc.

[0022] Specifically, the conveying part 8 is arranged obliquely in the opening 61. This can save the space occupied by the conveying part 8 and prevent the ballast at the outlet of the conveying part 8 from colliding with it. This can protect the conveying part 8. The conveying part 8 in this embodiment is arranged longitudinally. Figure 3 and Figure 4 As shown, the conveying part is arranged with the front lower and the rear higher, the discharge port of the conveying part 8 is arranged to face backward, and a screening assembly 9 for screening the crushed stones is arranged on one side of the connecting plate 6. The conveying part 8 conveys the ballast stones cleaned by the rake teeth 7 to the screening assembly 9, and the screening assembly 9 can screen the ballast stones according to the specification standards, and distinguish and place the ballast stones of different specifications screened out for subsequent processing.

[0023] Specifically, the size of the second guard plate 82 is larger than that of the first guard plate 81. The ballast stones raked by the rake teeth 7 enter the conveyor chain 84. At this time, the second guard plate 82 can prevent the ballast stones raked by the rake teeth 7 from being thrown out of the lateral working range of the conveyor chain 84, so that the conveyor chain 84 can transport a large number of ballast stones raked by the rake teeth 7 to the screening assembly 9 for screening.

[0024] As a further improvement, a vertical plate 10 is provided on the first guard plate 81, and a guide plate 11 is connected to the second guard plate 82 and the vertical plate 10. The guide plate 11 is arc-shaped, and its arc-shaped guide plate 11 can prevent the ballast stones on the conveyor chain 84 from being thrown out of the screen 93 and causing harm to people.

[0025] like Figure 1 and Figure 2 As shown, the hydraulic cylinder on the arm 5 pushes the connecting plate 6 to rotate, and the connecting plate 6 rotates around the connection point with the arm 5, and the rake teeth 7 are rotated to form a horizontal position to clean the ballast stones under the sleeper. When the rake teeth 7 are horizontal, the screening assembly 9 will tilt so that the ballast stones will automatically slide down after being screened by the screening assembly 9.

[0026] Specifically, the screening assembly 9 includes a waste frame 91 arranged on the connecting plate 6, a spring 95 is distributed on the waste frame 91, a screening frame 92 is arranged on the top of the spring 95, a screen 93 is arranged in the screening frame 92, a vibrator 94 is arranged on one side of the screening frame 92, an inclined plate 96 is arranged in the waste frame 91, and a discharge port is arranged on both the waste frame 91 and the screening frame 92. The ballast stones raked out by the rake teeth 7 are transported into the screening frame 92 through the conveying part 8, the vibrator 94 is started and drives the screen 93 in the screening frame 92 to vibrate, and the screen 93 begins to screen the ballast stones thereon, and the ballast stones smaller than the sieve holes of the screen 93 fall into the waste frame 91 and slide out of its discharge port along the inclined surface of the inclined plate 96. The ballast stones retained on the screen 93 slide out of its discharge port, completing the cleaning of ballast stones of different specifications.

[0027] Limiting posts 97 are evenly distributed at corresponding positions on the bottom surface of the sub-screening frame 92 and the top surface of the waste frame 91, and correspondingly arranged springs 95 are sleeved in the limiting posts 97 of the sub-screening frame 92 and the waste frame 91. There is a gap between the correspondingly arranged limiting posts 97, and the limiting posts 97 in the springs 95 can increase the contact surface between the limiting posts 97 and the springs 95, which can prevent the sub-screening frame 92 and the screen 93 from shaking greatly relative to the waste frame 91 under the action of the vibrator 94, causing the overload of the spring 95, and affecting the service life of the sub-screening assembly 9.

[0028] like Figure 5As shown, the discharge ports of the waste frame 91 and the sub-screen frame 92 are staggered. When the vibrator 94 is started, the ballast stones smaller than the sieve holes of the screen 93 will fall onto the inclined plate 96 and slide out through the outlet of the waste frame 91. The ballast stones on the screen 93 will slide out through the outlet of the sub-screen frame 92. Specifically, the outlet of the sub-screen frame 92 is set to face backward, while the outlet of the waste frame 91 is set to face right, so that ballast stones of different specifications are separated, which is convenient for the subsequent backfilling of the ballast stones falling from the screen 93 under the sleepers, thus eliminating the process of cleaning the ballast stones cleaned by the rake teeth 7 again through a bucket with sieve holes, saving time and effort and improving work efficiency.

[0029] Instructions for use: Move the cleaning machine body onto the rails, start the rake teeth 7, the conveying part 8 and the screening assembly 9, and then drive the upper arm 4 and the lower arm 5 to extend the rake teeth 7 under the sleepers to clean the compacted roadbed. The ballast stones cleaned by the rake teeth 7 are accumulated on the conveying part 8, and the conveying part 8 transports the ballast stones on its conveying chain belt 84 and transports them to the screening assembly 9. Then the screening assembly 9 screens the ballast stones and isolates and separates the ballast stones of different specifications. Subsequently, the ballast stones screened from the screen 93 can be backfilled under the sleepers by other machines.
