It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The first embodiment is as follows:

as shown in fig. 1 and 2, a coal separator for coal screening in a coal mine comprises a vibrating screen cavity 2 arranged on the coal separator 1, an electric linear guide rail 3 embedded on the inner wall of the head end of the vibrating screen cavity 2, and a screen 4 connected with a sliding seat of the electric linear guide rail 3, wherein the length direction frames on two sides of the screen 4 are connected with the vibrating screen cavity 2 through a rotating shaft A5, and a discharge hole 11 and an automatic switch door 6 which are arranged at the tail end of the vibrating screen cavity 2.

In this embodiment, as shown in fig. 1 and fig. 3, the number of the screen meshes 4 in the vibrating screen cavity 2 is greater than one, the head end of each screen mesh 4 is correspondingly provided with the electric linear guide 3, and the head end of each screen mesh 4 is connected to the sliding seat through a rotating shaft B7. The electric linear guide rail 3 can drive the screen 4 to be adjusted from a horizontal state to an inclined state.

In this embodiment, the tail end of each layer of the screen 4 is correspondingly provided with the discharge port 11 and the automatic opening and closing door 6; after the coal mines in each layer of screen 4 are screened, the screened coal mines can be discharged from the corresponding discharge ports 11 in a layering mode.

In this embodiment, the coal separator 1 is closed, a feeding opening 8 is formed in the top plate of the vibrating screen cavity 2 in the width direction, material is conveyed through the feeding opening 8, and the closed coal separator 1 can reduce dust overflow.

In this embodiment, the top of the length direction panels on the two sides of the vibrating screen cavity 2 is provided with a sliding chute 9, and the top plate is slidably connected with the sliding chute 9. The top plate of the vibrating screen cavity 2 can be opened and closed in a drawing mode, so that the vibrating screen cavity 2 can be cleaned or overhauled conveniently.

In this embodiment, as shown in fig. 1, the bottom surface of the vibrating screen cavity 2 is open, a conveyer belt 10 is arranged below the lowest layer of the screen 4, and a coal mine screened by the lowest layer of the screen 4 can directly fall onto the conveyer belt 10 to be conveyed out of the coal separator 1.

In this embodiment, as shown in fig. 4, the frame of the screen 4 includes an upper frame 4.1 and a lower frame 4.2, and the rotating shaft a5 connects the upper frame 4.1 or the lower frame 4.2. The upper frame 4.1 and the lower frame 4.2 are respectively provided with a corresponding fixing hole 4.3 and a corresponding fixing screw rod 4.4. The filter screen of screen cloth 4 is all around by the centre gripping in upper frame 4.1 and underframe 4.2, can be with convenient closure and the part of upper frame 4.1 and underframe 4.2 through fixed orifices 4.3 and set screw 4.2 to clear up or change the filter screen when screen cloth 4 is inconvenient to take off from shale shaker frame 2.

In this embodiment, as shown in fig. 5, a material guiding plate 12 is installed at the bottom of the discharging end of each screen 4 through a torsion spring; when the screen 4 is used for screening materials in a horizontal shape, one end of the material guide plate 12 is pressed by the automatic switch door 6, and at the moment, the material guide plate 12 is in a vertical structure with the screen 4, so that the vibration screening work of the screen 4 cannot be influenced. When the screen 4 is inclined to discharge the mineral aggregate from the discharge port of the automatic opening and closing door 6, the automatic opening and closing door 6 is opened, the guide plate 12 can automatically rotate under the elasticity of the torsion spring when one end of the guide plate 12 is not pressed, and the guide plate 12 can guide the mineral aggregate to the discharge port 11. The guide plate 12 can prevent mineral aggregate from falling into the screening chamber of the lower layer due to the overlarge gap between the screen 4 and the discharge opening 11.

The specific implementation mode is as follows: the colliery is from 8 input shale shaker chambeies of pan feeding mouth 2, can set up the vibration screening time in colliery, when the time reaches the back, signal of telecommunication transmission is to the electronic linear guide 3 that corresponding screen cloth 4 connects on, electronic linear guide 3 drives the rotatory slope form that is in the low side for the tail end of screen cloth 4, then automatic switch door 6 that the screen cloth 4 tail end corresponds can be opened, the colliery after the screening can be followed screen cloth 4's inclined plane and rolled from shale shaker intracavity 2 and fallen away, the colliery rolls out and can carry out next batch of screening after finishing, it is rotatory to the level form to drive screen cloth 4 through electronic linear guide 3 during next batch of screening, in order to avoid screen cloth 4 to be when the slope form the material along the inclined plane smooth roll gather to the screening efficiency in same department influence colliery.
