[0053] A hose 10, one end of which is connected to one end of the air pipe 7, and the other end of which is connected to the fan 9;

[0054] The fan 9 can transport the outside air into the hose 10, and then transport it into the air pipe 7 through the hose 10, and then spray it out from the air outlet 8, so as to blow out some stones with a volume similar to that of the screen 4 and the sand stuck in the mesh of the screen 4 to prevent it from clogging the screen 4;

[0055] The vibration device is arranged in the box body 1 and is used to make the C-shaped frame 3 vibrate.

[0056] Specifically, the vibration device includes:

[0057] Two pairs of fixing blocks 11 are respectively arranged on the inner side walls of the box body 1;

[0058] A fixing rod 12 is fixedly mounted on the upper end surface of the fixing block 11;

[0059] There are two pairs of connecting plates 13, both of which are arranged on the outer wall surface of the C-shaped frame 3 and are slidably connected to the two pairs of fixing rods 12 respectively;

[0060] A compression spring 14 is disposed between the fixing block 11 and the connecting plate 13 and is wound around the outer surface of the fixing rod 12;

[0070] Specifically, a baffle 22 is fixedly installed on the lower end surface of the box body 1 and below one end of the C-shaped frame 3;

[0071] The baffle 22 can block the screened sand and separate the screened sand from the unscreened sand to prevent them from mixing and affecting the quality.

[0072] Working principle: first, the staff starts the vibration motor 16, and the vibration motor 16 can vibrate the fixed frame 15. At this time, under the action of the compression spring 14, the C-shaped frame 3 can drive the screen 4 to vibrate. At this time, the staff adds sand from the feed hopper 2 to the box body 1, and the sand in the feed hopper 2 falls onto the screen 4, which is screened by the screen 4. After the screening is completed, the staff turns off the vibration motor 16, and at the same time, turns the locking pin 20 to disengage it from the locking ring 21, and starts the fan 9 at the same time. The fan 9 can transport the outside air to the hose 10, and then transport it to the air pipe 7 by the hose 10, and then spray it out from the air outlet 8. At this time, the staff pushes the sliding block 6 to make it slide in the sliding port 5 and drive the air pipe 7 to move. At this time, the air sprayed from the air outlet 7 can blow out some sand with a volume similar to that of the screen 4 and the sand stuck in the mesh of the screen 4 to prevent it from clogging the screen 4, thereby completing the cleaning of the screen 4 and bringing convenience to people.
