[0028] A vibration transmission seat 6 is welded to the lower surface of the top fixing frame 4 , and a vibration motor 7 is installed in the middle of the vibration transmission seat 6 .

[0029] It should be noted that, when sand is scattered on the surface of the screen 5, the vibration motor 7 is fixed under the top fixing frame 4 through the vibration transmission seat 6. The vibration motor 7 generates high-frequency vibration when working, and the vibration is transmitted to the screen 5 through the vibration transmission seat 6. The bottom of the screen 5 is supported by the buffer spring 2, so that the screen 5 can be continuously swung, and the fine sand in the sand falls from the screen 5. The large particles of sand or sand grains blocked by the screen 5 slide along the screen 5 under the action of gravity, so that the large particles of sand or sand grains are diverted to one end of the screening device, and the fine sand falls on the sand guide plate 14 under the action of gravity. The fine sand is diverted to the other end of the screening device through the sand guide plate 14, so that the fine sand and large particles of sand or sand grains can be quickly screened, and there is no need to dump the filtered large particles of sand or sand grains during use, which can improve the screening efficiency of the sand.

The telescopic supporting legs 10 can adjust the height of the screening device so as to adjust the height of the screen 5 and the sand guide plate 14 from the ground. When in use, more fine sand, large-grained sand or sand grains can be stored under the screen 5 and the sand guide plate 14, making it more convenient to use.

[0036] The working principle and use process of the utility model are as follows: sand is thrown on the surface of the screen 5, and the vibration motor 7 is fixed under the top fixing frame 4 through the vibration transmission seat 6.

The bottom of the screen 5 is supported by the buffer spring 2, so that the screen 5 can be continuously swung, and the fine sand in the sand falls from the screen 5. The large particles of sand or sand blocked by the screen 5 slide along the screen 5 under the action of gravity, so that the large particles of sand or sand are guided to one end of the screening device, and the fine sand falls on the sand guide plate 14 under the action of gravity. The fine sand is guided to the other end of the screening device, which can realize the rapid screening of fine sand and large sand particles or sand grains. There is no need to dump the filtered large sand particles or sand grains during use, which can improve the screening efficiency of the sand. The bottom of the screening device is supported by the telescopic support legs 10. The telescopic support legs 10 can be locked by the locking screw rod 13 after telescopic adjustment. The telescopic support legs 10 can adjust the height of the screening device so as to adjust the height of the screen 5 and the sand guide plate 14 from the ground. More fine sand, large sand particles or sand grains can be stored under the screen 5 and the sand guide plate 14 during use, which is more convenient to use.
