[0030] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figures 1-8 This invention provides three technical solutions:

[0033] A driving mechanism includes a horizontally mounted load-bearing beam 5 on one side of the upper end of a suspended screen box 2. A connecting rail 6 is horizontally mounted at the center of the upper end of the load-bearing beam 5. A power support 7 is horizontally mounted on the upper end of the connecting rail 6. A power assembly, including a hydraulic motor 8 and an eccentric wheel 11, is horizontally mounted on the upper end of the power support 7. A flange is provided on one side of the connecting rail 6, and one side of the power support 7 abuts against the flange of the connecting rail 6. A connecting groove 12 is horizontally extended through the lower end of the power support 7, movably connecting the connecting rail 6. Both the connecting groove 12 and the connecting rail 6 have T-shaped cross-sections. Two support plates 9 are vertically and symmetrically arranged on one side of the upper end of the power support 7. The hydraulic motor 8 is horizontally arranged on the side of the upper end of the power support 7 near the support plate 9. The output shaft 10 is horizontally arranged in the middle of one side of the hydraulic motor 8. The output shaft 10 passes through the two support plates 9 horizontally through the bearing. The eccentric wheel 11 is sleeved on the side of the output shaft 10 located between the two support plates 9. The output shaft 10 of the hydraulic motor 8 controls the high-speed rotation of the eccentric wheel 11. Under the action of the eccentric shaking principle of the eccentric wheel 11, the suspended screen box 2 can be driven to shake rapidly to provide power for screening.

[0034] The hydraulic motor 8 can be a common high-speed hydraulic motor in the prior art.

[0035] Example 2

[0036] Based on Embodiment 1, the power support 7 and hydraulic motor 8 are installed. A mounting and retaining assembly is movably mounted on one side of the connecting rail 6. The mounting and retaining assembly includes a constraint plate 14 and a slide block 22. One side of the constraint plate 14 abuts against the power support 7. A flip groove 13 is provided on the horizontal section of the connecting rail 6 away from the edge. One side of the constraint plate 14 is inserted into the flip groove 13 via a first self-rotating pin. When the constraint plate 14 is vertically mounted, one side of the constraint plate 14 abuts against the end of the power support 7. An access groove is provided on the upper end of the side of the hydraulic motor 8 near the constraint plate 14. An access row 15 is horizontally arranged in the access groove. A hydraulic line 17 is connected to one side of the access row 15 via a connecting nut 16. The upper end of one side of the constraint plate 14 is connected to the end of the connecting nut 16. The connecting rail 6 has a vertical groove 20 on one side, and a sliding groove 21 is provided at the lower end of each groove 20. The sliding block 22 is horizontally and movably inserted into the sliding block 22. A support block 23 is vertically provided on one side of the upper end of the sliding block 22. The upper end of the support block 23 is movably inserted through the groove 20, and a support arm 19 is movably inserted through the upper end of the support block 23 through the groove 20 via a second self-rotating pin. A clearance groove 18 is provided on the side of the constraint plate 14 away from the power support 7. The support arm 19 is inclinedly inserted into the clearance groove 18 on the side of the support block 23 via a third self-rotating pin. The T-shaped connection and assembly is simple and convenient to operate and easy to use during later maintenance. After the power support 7 is installed, it can be quickly fixed by the constraint plate 14.

[0037] In addition, the vertical contact of the constraint plate 14 can not only clamp and limit the power support 7, but also limit the connection nut 16 connected to the hydraulic motor 8, so as to prevent the connection nut 16 from loosening due to the vibration of the suspended screen box 2 and the hydraulic motor 8, thereby improving the stability of the hydraulic motor 8.

[0038] Example 3

[0039] Based on Embodiment 2, the positions of the constraint plate 14 and the slide block 22 are limited and fixed. The limiting component is located on one side of the slide block 22 and includes a spring box 24 and a limiting rod 25. The spring box 24 is vertically located on one side of the upper end of the slide block 22. A spring groove is opened in the support block 23. The limiting rod 25 is vertically and movably inserted into the spring groove. The upper and lower ends of the limiting rod 25 pass through the spring box 24 and the slide block 22, respectively. A limiting groove 26 is opened on one side of the lower end of the slide groove 21. When the constraint plate 14 is vertically set, the lower end of the limiting rod 25 is inserted into the limiting groove 26. A pressure block is horizontally provided at the lower end of the limiting rod 25 located in the spring groove. Each of the limit rods 25 is fitted with a downward pressure spring 27 at the upper end of the pressure block. When the constraint plate 14 is set horizontally, the upper ends of the constraint plate 14 and the limit rods 25 passing through the spring box 24 are flush with the upper end of the connecting rail 6. When it is necessary to push the constraint plate 14 vertically, the constraint plate 14 is pulled up directly by hand. Under the pulling action of the support arm 19, the slide seat 22 slides horizontally in the slide groove 21. When the limit rod 25 reaches the position of the limit groove 26, the limit rod 25 automatically inserts into the limit groove 26 to fix the position of the slide seat 22. At this time, the constraint plate 14 abuts against the power support 7 and the connecting nut 16 to limit and fix it.

[0040] During disassembly, lift the limit rod 25, allowing the slide block 22 to move freely. Horizontally adjust the constraint plate 14, and the power support 7 can slide horizontally out from above the connecting rail 6. The operation is simple, convenient, and durable.

[0041] A suspended vibrating screen has the aforementioned drive mechanism, including a loader connecting frame 1. Two shock absorber seats 4 are symmetrically arranged on both sides of the loader connecting frame 1. A suspended screen box 2 is suspended inside the loader connecting frame 1. Angle irons are provided on the side of the suspended screen box 2 near the shock absorber seats 4. The lower end of the angle irons is connected to the upper end of the shock absorber seats 4. A screen 28 is horizontally arranged at the lower end of the suspended screen box 2. An inclined shovel platform 3 is inclined on one side of the loader connecting frame 1, and the upper end of the inclined shovel platform 3 is flush with the screen 28.

[0042] When the hydraulic motor 8 vibrates the suspended screen box 2 at high speed, it receives auxiliary force under the elastic buffering effect of the shock absorber 4. The rear end of the loader connecting frame 1 can be equipped with a standard connecting part that is compatible with the loader. When the loader connecting frame 1 is connected to the loader, the hydraulic motor 8 is driven to perform the screening operation of the suspended screen box 2 through the hydraulic pressure output of the standard loader, which meets the complex operation scenario of construction site, saves the participation of additional auxiliary equipment (repeated shoveling and transporting), and greatly reduces excessive labor cost consumption.

[0043] The hydraulic flow rate can be controlled by adjusting the flow valve, a suitable vibration frequency can be selected, and the excitation force can be adjusted to meet actual needs by adjusting the control pressure.

[0044] In addition, the screen 28 can be detachably connected via a multi-bolt structure, allowing for the selection of appropriate aperture screen 28 for different construction scenarios.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
