An installation frame is fixedly installed on the upper surface of one end of the conveyor. A screening barrel is fixedly installed inside the installation frame. One end of the screening barrel penetrates through the installation frame and extends to the outside. The hopper is installed at the upper end of the installation frame, and its bottom extends to the inside of the screening barrel.

[0006] A rotating rod is arranged inside the screening barrel. Stirring blades are connected to the surface of the rotating rod. One end of the rotating rod penetrates through one end of the screening barrel and is connected to a second transmission wheel. A transmission belt is installed on the surface of the second transmission wheel. One end of the transmission belt is installed with a first transmission wheel. One side of the first transmission wheel is connected to a first servo motor, and the first servo motor is installed on the surface of one side of the conveyor.

[0007] Furthermore, bearings are installed on both sides of one end of the conveyor. A connecting rod is installed inside the bearings. One end of the connecting rod is connected to a hydraulic rod, and the hydraulic rod is installed inside the support frame.

[0008] Even further, a second servo motor is installed on one side of the other end of the conveyor, and the output end of the second servo motor is connected to the inside of the conveyor.

[0009] Furthermore, the support frame is arranged at the lower end of one end of the conveyor, and a first roller is installed at the bottom of the support frame, and multiple groups of the first rollers are provided.

[0010] Furthermore, the lower surface of the other end of the conveyor is connected with a bottom plate, and a second roller is installed at the bottom of the bottom plate, and two groups of the second rollers are provided.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The first servo motor drives the first transmission wheel to rotate, thereby driving the rotation of the installed part. The rotation of the transmission belt drives the second transmission wheel to rotate. The rotation of the second transmission wheel drives the connected rotating rod to rotate, thereby driving the stirring blades connected to the surface to rotate in the screening barrel, driving the coal in the screening barrel to be stirred, so that the fine coal falls on the conveyor through the holes opened on its lower surface, and the large materials screened out are continuously stirred by the stirring blades and discharged to the outside through one end of the screening barrel.

[0013] 2. Hydraulic rods are installed on both sides of one end of the conveyor. By the up and down movement of the hydraulic rods, the one end of the conveyor is driven to move up and down, and thus the coal can be transported to different heights. BRIEF DESCRIPTION OF THE DRAWINGS
