Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

The first embodiment:

as shown in fig. 1-2, an improved vibratory high frequency screen is provided for the present invention, comprising: the vibrating screen comprises a vibrating screen body, wherein a vibrating frame 1 is arranged on the vibrating screen body, a screen 2 is arranged in the vibrating frame 1, a liftable T-shaped baffle 3 is movably mounted on the vibrating frame 1, the distance between the bottom of the T-shaped baffle 3 and the screen 2 is adjustable, so that particle objects in a certain range can pass through the space between the T-shaped baffle 3 and the screen 2, and larger particles cannot pass through the space, and the larger particles are blocked by the T-shaped baffle 3, so that larger stones or coal blocks can be prevented from rolling down along the screen 2 to break transportation equipment or threaten life safety of personnel; through setting up T shape baffle 3, can also play material blanking flow on the regulation shale shaker for blanking flow is controllable, avoids more material once only to fall to conveyer, gives conveyer area point pressure, thereby more is favorable to conveyer's stable transportation.

As shown in fig. 2, both sides of the T-shaped baffle 3 are fixedly provided with a square 4, two of the square 4 are provided with a screw 5, the screw 5 is in threaded connection with the square 4, the ends of the two threaded rods 5 are rotatably provided with a fixing block 6, the fixing blocks 6 are fixedly connected with the vibration frame 1, and the two screws 5 are rotated simultaneously, so that the square 4 can move upwards or downwards, the T-shaped baffle 3 can be adjusted, and the distance between the T-shaped baffle 3 and the screen 2 can be changed.

As shown in fig. 1, the equal fixed mounting in both sides of vibration frame 1 has pneumatic cylinder 7, two equal fixed mounting has splint 8, two on the output shaft of pneumatic cylinder 7 splint 8 all are located vibration frame 1, start two pneumatic cylinders 7 and can make two splint 8 be close to each other, until the contact, when T shape baffle 3 blockked the stone or the coal cinder of great piece, two splint 8 can extrude stone or coal cinder to crowded garrulous stone or coal cinder, thereby make things convenient for stone or coal cinder to pass through the gap between T shape baffle 3 and the screen cloth 2.

As shown in fig. 1, further, two one side that splint 8 is close to each other all has a plurality of bumps, broken stone or coal cinder that the setting of bump can be more convenient, and simultaneously, the bump also can increase the frictional force between stone or coal cinder and splint 8, avoids stone or coal cinder and splint to skid.

When the crusher is used, stones or coal blocks enter the vibrating frame 1, move along the screen 2 and penetrate through gaps between the screen 2 and the T-shaped baffle 3, if larger stones or coal blocks fall on the screen 2, the T-shaped baffle 3 plays a role in blocking the larger stones or coal blocks, at the moment, whether the crusher is stopped or not is selected according to the field situation, then the larger stones or coal blocks are crushed, and the two hydraulic cylinders 7 are simultaneously started to enable the two clamping plates 8 to be close to each other, so that the larger stones or coal blocks are crushed; larger stones or coal blocks can be screened according to requirements, and during screening, the position of the T-shaped baffle 3 can be adjusted by simultaneously rotating the two screws 5, so that the width of a gap between the screen 2 and the T-shaped baffle 3 can be changed;

if the entering amount of the stone or coal blocks is large, the flow rate of the materials falling from the vibrating screen to the conveying device can be adjusted by adjusting the width of the gap between the T-shaped baffle 3 and the screen 2.
