[0013] Step 3: When the tungsten ore to be screened in the feeding inner cylinder is completely discharged, the multi-stage electric push rod is started again, so that the discharging frame can be driven to reset through the baffle plate. At this time, an appropriate amount of tungsten ore to be screened is introduced into the feeding inner cylinder again, and the discharging frame will be connected to the discharging slot again, and then the qualified tungsten ore will fall into the discharging frame;

[0014] Step 4, repeating step 2 and step 3, so that the tungsten ore to be screened can be screened step by step and the tungsten ore that has passed the screening can be gradually discharged through the discharge guide chute;

[0015] The fifth step is to start the electric telescopic rod after the screening operation is completed, thereby driving the limit clamping tooth to move to the side close to the fixed support plate, thereby completely separating the limit clamping tooth from the driven gear, and then closing the electric telescopic rod and starting the second motor, thereby driving the driving gear to rotate, thereby driving the corresponding side connecting shaft to rotate through the driven gear, and further cooperating with the use of the other side connecting shaft to drive the screening outer frame to rotate, thereby driving the screening hole frame to rotate, and after turning the screening hole frame over, closing the second motor and starting the first motor again, thereby driving the screening hole frame to move back and forth again, thereby facilitating the removal of the tungsten ore blocking the holes of the screening hole frame, thereby facilitating the cleaning of the tungsten ore blocking the holes of the screening hole frame, and avoiding the siltation and blockage of the screening hole frame due to long-term use, thereby ensuring the normal use of the screening mechanism, and after the cleaning is completed, resetting the screening hole frame and making the limit clamping tooth mesh with the driven gear again.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the coordinated use of the screening barrel box, the screening frame box, the screening mechanism and the turning mechanism, the side-connected rotating block can be driven to make an inclined cyclic reciprocating movement, thereby driving the screening hole frame to make an inclined cyclic reciprocating movement, and then the tungsten ore to be screened can be effectively screened and stored separately, and the screening hole frame can be conveniently turned over and stably limited, so as to facilitate the removal of the tungsten ore blocking the holes of the screening hole frame, thereby providing convenience for cleaning the tungsten ore blocking the holes of the screening hole frame, thereby avoiding the siltation and blockage of the screening hole frame due to long-term use, thereby ensuring the normal use of the screening mechanism;

[0018] 2.

[0019] 3. Through the setting and use of the feeding mechanism, the first arc-shaped material trough and the second arc-shaped material trough can be offset during the feeding period, thereby realizing the discontinuous separation of the screening space and the feeding space, and then realizing the connection only when the material is guided to the screening mechanism, thereby further preventing the dust generated by the tungsten ore screening from spreading to the external environment, and realizing the linkage cooperation between the feeding mechanism and the discharging mechanism, without the need to add driving equipment, thereby further saving processing costs.
