[0021] Example

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a digging device of a screening machine includes a mounting shell 1, a plurality of slide bars 2 are evenly arranged on the bottom of the mounting shell 1, a bottom plate 3 is arranged at the bottom end of the slide bar 2, and a plurality of rollers 4 are arranged on the bottom plate 3. Under the action of the rollers 4, in conjunction with the driving assembly, the device can be driven to move as a whole, so that the device can perform digging work. A fixing plate 201 is arranged at the bottom end of the slide bar 2. Under the action of the fixing plate 201, the connection quality between the slide bar 2 and the bottom plate 3 is guaranteed, thereby ensuring the use efficiency of the device.

[0023] A lifting plate 6 is slidably provided on the slide bar 2, and a digging claw 8 is provided on the lifting plate 6 through a toothed belt. A driving shaft 7 is also rotatably provided on the lifting plate 6, and a gear is provided on the driving shaft 7 through a key connection. The gear and the teeth on the belt are meshed with each other. At this time, the driving shaft 7 can drive the digging claw 8 on the toothed belt to move through the gear, so that the digging claw 8 can move, and then the ballast under the track is excavated. A motor 11 is also provided on the top of the lifting plate 6 through a support plate 10, and a second bevel gear 1 is provided on the power output shaft of the motor 11 through a coupling. 2. The driving shaft 7 is also provided with a first bevel gear 9 through a key connection. The first bevel gear 9 and the second bevel gear 12 are meshed with each other. At this time, the starting motor 11 can drive the driving shaft 7 to rotate through the second bevel gear 12 and the first bevel gear 9, thereby driving the excavation claw 8 to move through the gears and the toothed belt, so as to excavate the ballast under the track. At the same time, the height of the excavation claw 8 can be adjusted by using the lifting plate 6, so that the device can better meet the actual excavation needs, and the applicability of the device is improved to a certain extent.

[0024] A threaded rod 5 is also rotatably provided on the mounting shell 1, and the bottom of the threaded rod 5 is connected to the bottom plate 3 through a rotating sleeve. At this time, under the action of the rotating sleeve, the rotation efficiency of the threaded rod 5 is guaranteed. The threaded rod 5 passes through the lifting plate 6 and is threadedly connected to the lifting plate 6. At this time, rotating the threaded rod 5 can drive the lifting plate 6 to move on the sliding rod 2, thereby adjusting the height of the lifting plate 6.

[0025] A cavity is also provided inside the mounting shell 1, and the top of the threaded rod 5 passes through the cavity and extends into the cavity. The top end of the threaded rod 5 is located inside the cavity and is also provided with a third bevel gear 13 through a key connection. A rotating shaft 14 is also rotatably provided in the cavity, and a fourth bevel gear 15 is provided on the rotating shaft 14 through a key connection. The fourth bevel gear 15 is meshed with the third bevel gear 13. At this time, rotating the rotating shaft 14 can drive the threaded rod 5 to rotate through the fourth bevel gear 15 and the third bevel gear 13.

[0026] A worm wheel 16 is also provided on the rotating shaft 14 through a key connection, and a worm 17 is also rotatably provided on the mounting shell 1. The worm 17 and the worm wheel 16 are meshed with each other. The worm 17 passes through the mounting shell 1 and is rotatably connected to the worm 17. At this time, rotating the worm 17 can rotate the worm wheel 16, thereby rotating the threaded rod 5, and thus better moving the lifting plate 6. In addition, because the worm 17 and the worm wheel 16 have a self-locking function, the height of the lifting plate 6 after adjustment can be limited, thereby ensuring the use efficiency of the excavation device. A rotary handle 1701 is provided at the top end of the worm 17, and the worm 17 can be driven to rotate by rotating the rotary handle 1701, thereby driving the threaded rod 5 to rotate through the worm 17, the worm wheel 16, the fourth bevel gear 15 and the third bevel gear 13.

[0027] In actual use, when it is necessary to clean the ballast under the track, the staff can move the device through the driving assembly and the roller 4, and then start the motor 11 to use the second bevel gear 12, the first bevel gear 9 and the driving shaft 7 to drive the gear to rotate, so as to use the toothed belt to drive the excavation claw 8 to move on the lifting plate 6 to achieve the purpose of excavating the ballast. In addition, when it is necessary to adjust the working height of the excavation claw 8, the staff turns the handle 1701 to use the worm 17, the worm wheel 16, the fourth bevel gear 15 and the third bevel gear 13 to drive the threaded rod 5 to rotate, thereby driving the lifting plate 6 to move on the slide bar 2, and then adjusting the height of the lifting plate 6, thereby adjusting the height of the excavation claw 8, so that the device can better meet the actual use needs. In addition, under the self-locking function of the worm 17 and the worm wheel 16, it is ensured that the lifting plate 6 can remain stable after being adjusted to the appropriate height and will not be accidentally moved, thereby ensuring the use efficiency of the excavation device.
