A set of compression springs 14, which are fixedly connected to the upper side of the support frame 11, is provided on the rear side of the motor base 12. An annular seat 15 is fixedly connected to the upper side of the compression springs 14. The vibration amplitude of the screening barrel body 21 can be limited by the compression springs 14 and the annular seat 15, so that the screening barrel body 21 can maintain vibration without tipping over.

Hot air can be discharged through the exhaust box 37 and the exhaust nozzle 38 to dry the river sand.

[0029] Workflow: Before use, install the support frame 11 in a suitable position and connect the power supply. This device is equipped with an external controller, which is electrically connected to the vibrating motor 13, feed valve 25, discharge valve 26, rotary motor 31, and hot air blower 34. Manual operation of the external controller allows adjustment of the operating status of the vibrating motor 13, feed valve 25, discharge valve 26, rotary motor 31, and hot air blower 34. All of the above are existing technologies. When using this device, the operator first opens the feed valve 25 through the external controller, allowing a suitable amount of washed river sand to be added into the screening tank body 21. Then, the feed valve 25 is closed. Simultaneously, the vibrating motor 13, rotary motor 31, and hot air blower 34 are started. The vibrating motor 13, fixed to the motor base 12, causes the screening barrel body 21, fixed to the annular seat 15, to vibrate. The vibration amplitude of the screening barrel body 21 is limited by the compression spring 14 and the annular seat 15, allowing the screening barrel body 21 to maintain vibration without tipping over. At the same time, the rotating motor 31, fixed to the motor frame 29, drives the rotating air conveying shaft 32 and the stirring rod 33 to rotate. The stirring rod 33 stirs the river sand, allowing it to be quickly screened by the first screen plate 22, the second screen plate 23, and the third screen plate 24. The river sand that meets the requirements falls onto the upper side of the first screen plate 22, the second screen plate 23, and the third screen plate 24, respectively. Excessive river sand and accumulated water flow out through the bottom opening of the screening barrel body 21. Simultaneously, the hot air blower 34 drives the exhaust pipe to... A negative pressure is created inside the screening drum 21. The dust filter plate 28 filters the air inside the screening drum body 21 and sends it into the hot air blower 34 through the exhaust pipe 35. The hot air blower 34 heats the air and then delivers it to the air delivery chamber of the rotating air delivery shaft 32 through the air delivery plate 36. The rotating air delivery shaft 32 delivers the hot air to the exhaust box 37 and then sprays it downwards through the exhaust nozzle 38. The hot air heats and dries the river sand that is agitated by the vibration of the screening drum body 21 and the stirring of the stirring rod 33. Thus, the river sand can be screened and dried simultaneously. After a period of time, the operator can use the external controller to turn off the vibration motor 13, the rotating motor 31, and the hot air blower 34, and then open the three discharge valves 26 in sequence. The discharge pipe 27 guides the river sand of different fineness to be discharged separately. The device can vibrate the screening barrel body 21 by the vibrating motor 13, stir the river sand by the stirring rod 33, heat the air by the hot air blower 34, and divide the hot air by the air delivery plate 36 and the rotating air delivery shaft 32. The hot air is discharged through the exhaust box 37 and the exhaust nozzle 38. The circulating hot air dries and dehydrates the river sand on the first screen plate 22, the second screen plate 23, and the third screen plate 24. This method can quickly dry the river sand that has clumped due to moisture, improve the screening speed of river sand, and disperse the river sand that was originally piled up for drying onto different screen plates and continuously turn it over, thereby improving the drying and dehydration speed. This method is time-saving and highly efficient.
