Due to the fixed connection between the connecting frame 6 and the first rotating rod 4, the connecting frame 6 rotates together. Due to the rotational connection between the connecting frame 6 and the second rotating rod 7, the friction between the tungsten and the second crushing rod 8 is increased through the cooperation of the grinding blade 11, and the second rotating rod 7 rotates with the first rotating rod 4, thereby reducing the crushing dead angle in the cylinder 1;

[0034] Reference Figure 1-4The reflux mechanism includes a transmission rod 9 and a spiral blade 10. The transmission rod 9 is arranged on the right side of the cylinder 1. The spiral blade 10 is fixedly installed on the surface of the transmission rod 9. A protective shell 14 is fixedly installed on the right side of the cylinder 1. The transmission rod 9 is rotatably sleeved inside the protective shell 14. A discharge port 15 is installed on the right side of the cylinder 1. The inner cavity of the discharge port 15 is connected to the inner cavity of the cylinder 1 and the inner cavity of the protective shell 14. A rotating wheel is sleeved on the surface of the first rotating rod 4 and the transmission rod 9. A transmission belt 16 is sleeved between the first rotating rod 4 and the transmission rod 9 through the rotating wheel. A beating blade 19 is fixedly installed on the surface of the first rotating rod 4. A bearing rod 20 is fixedly installed on the top of the bottom plate 2. By setting the reflux mechanism, the beating blade 19 is driven to rotate when the first rotating rod 4 rotates.

A solenoid valve is installed on the surface of the discharge port 15. When the solenoid valve is opened, since the surface of the first rotating rod 4 is installed with a rotating blade 13, the tungsten remaining on the surface of the filter screen 12 enters the interior of the protective shell 14 through the discharge port 15. Through the cooperation of the transmission belt 16, the first rotating rod 4 rotates and drives the second rotating rod 7 to rotate, so that the spiral blade 10 rotates together. Since the shape of the spiral blade 10 is a spiral rising setting, the tungsten that does not meet the specifications is transported upward through the spiral blade 10. Since the top of the inner wall of the protective shell 14 is inclined and connected to the cavity 3, the tungsten re-enters the interior of the cylinder 1 for crushing, thereby solving the problem in the prior art that the staff needs to pick out the larger tungsten and reprocess it.

[0035] Specifically, the working process or working principle of the tungsten crushing and grinding device is as follows: when in use, the motor 21 is started to drive the first rotating rod 4 and the first crushing rod 5 to rotate. Due to the fixed connection between the connecting frame 6 and the first rotating rod 4, the connecting frame 6 rotates together. Due to the rotation connection between the connecting frame 6 and the second rotating rod 7, the friction between the tungsten and the second crushing rod 8 is increased through the cooperation of the grinding leaves 11, and the second rotating rod 7 rotates with the first rotating rod 4. When the first rotating rod 4 rotates, it drives the beating leaves 19 to rotate, and through the cooperation of the bearing rod 20, the spring 17 and the damper 18, the filter screen 12 inside the cylinder 1 vibrates, and the qualified tungsten passes through the filter screen 12. The oversized tungsten is intercepted by the filter screen 12, and the surface of the discharge port 15 is installed with a solenoid valve. When the solenoid valve is opened, the tungsten remaining on the surface of the filter screen 12 enters the interior of the protective shell 14 through the discharge port 15 because the surface of the first rotating rod 4 is installed with a rotating blade 13. Through the cooperation of the transmission belt 16, the first rotating rod 4 rotates to drive the second rotating rod 7 to rotate, so that the spiral blade 10 rotates together. Since the shape of the spiral blade 10 is a spiral rising setting, the tungsten that does not meet the specifications is transported upward through the spiral blade 10. Since the top of the inner wall of the protective shell 14 is inclined and connected with the cavity 3, the tungsten re-enters the interior of the cylinder 1 for crushing.
