[0011] Preferably, the discharging barrel is a triangular prism-shaped barrel, and a discharging groove is provided on the inner side of the discharging barrel, and the groove opening at the upper end of the discharging groove is larger than the groove opening at the lower end.

[0012] The present invention provides a mineral particle screening device having the following beneficial effects:

[0013] (1) The mineral particle screening device is provided with a screening mechanism and a discharging mechanism. When the screening device is used, the mineral particles in the screening cylinder are moved to avoid the mineral particles being stuck in the screen and continuously clogging the screening cylinder, thereby reducing the screening efficiency of the screening device.

[0014] (2) In the mineral particle screening device, when the mineral particles are within the set size, they fall from the screening cylinder through the fixed cylinder and fall into the discharge cylinder. When the mineral particles fall, they contact the elastic plate. At this time, the collision force generated by the mineral particles causes the elastic plate to deform, and the air between the elastic plate and the discharge cylinder is squeezed. The squeezed air forms resistance to slow down the deformation of the elastic plate, thereby reducing the falling speed of the mineral particles and preventing the mineral particles from hitting the discharge cylinder and causing damage to the discharge cylinder.

[0015] (3) In the mineral particle screening device, when the air between the elastic plate and the discharge barrel is squeezed, the elastic membrane is deformed by force, and the fixed balls on the elastic membrane move accordingly. With the cooperation of the elastic membrane, the fixed balls move continuously, thereby causing the elastic plate to vibrate continuously, allowing the mineral particles to escape from the discharge barrel more quickly, thereby preventing the mineral particles from staying on the elastic plate.

[0016] (4) In the mineral particle screening device, when larger-sized mineral particles are stuck in the fixed cylinder, the hollow ring inside the cavity continuously squeezes or stretches the spring as the screening cylinder rotates. When the hollow ring moves, the annular contact piece continuously contacts the resistance ring. When the annular contact piece passes through the resistance ring, the fixed cylinder is deformed by force. The deformed fixed cylinder squeezes the mineral particles inward, causing the fixing angle of the mineral particles to change.

[0017] (5) In the mineral particle screening device, the elastic strip moves toward the through hole driven by the counterweight ball, and the counterweight ball generates a magnetic repulsive force on the hollow ring, thereby strengthening the squeezing of the hollow ring on the spring, making the fixation of the mineral particles by the fixed tube looser. The counterweight ball moving toward the through hole contacts the mineral particles. When the elastic strip drives the counterweight ball to return, the mineral particles are pushed to the outside of the fixed tube, thereby preventing the mineral particles from being stuck in the through hole, causing the through hole to be blocked and affecting the screening efficiency of the device.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] See also Figure 1-7 The present invention provides a technical solution: a mineral particle screening device, comprising a base 1, a fixing frame 2 is fixedly installed on the top of the base 1, a motor 3 is fixedly installed on the right side of the fixing frame 2 near the upper end through a fixing rod, a screening mechanism 4 is arranged at the upper end of the base 1, a discharging mechanism 5 is arranged at the lower end of the base 1, and a rotating baffle 6 is arranged on the outer side of the screening mechanism 4.

[0029] The screening mechanism 4 includes a rotating shaft 41, a screening cylinder 42, a through hole 43, a toggle member 44 and a fixed cylinder 45. The rotating shaft 41 is rotatably mounted on the upper end of the fixed frame 2. The right end of the rotating shaft 41 is fixedly connected to the output shaft of the motor 3. The screening cylinder 42 is fixedly mounted on the outer side of the rotating shaft 41 through a fixed rod. The through hole 43 is provided on the outer surface of the screening cylinder 42. The toggle member 44 is arranged on the inner side of the screening cylinder 42. The toggle member 44 includes an elastic strip 441 and a counterweight ball 442. The elastic strip 441 is fixedly mounted on the screening cylinder 4 2 is close to the through hole 43, the elastic strip 441 is bent toward the through hole 43, the weight ball 442 is fixedly installed at one end of the elastic strip 441 away from the inner center of the screening cylinder 42, the elastic strip 441 moves toward the through hole 43 under the drive of the weight ball 442, the weight ball 442 generates a magnetic repulsion on the hollow ring 453, strengthens the compression of the hollow ring 453 on the spring, makes the fixing of the fixed cylinder 45 to the mineral particles looser, the weight ball 442 moving toward the through hole 43 contacts the mineral particles, when the elastic strip 441 When the counterweight ball 442 is driven to return, the mineral particles are pushed to the outside of the fixed cylinder 45. The fixed cylinder 45 is fixedly installed on the inner side of the through hole 43. The fixed cylinder 45 includes a cavity 451, a resistance ring 452, a hollow ring 453 and an annular contact sheet 454. The cavity 451 is opened on the inner side of the fixed cylinder 45. The resistance ring 452 is fixedly installed on the inner side of the cavity 451. The hollow ring 453 is installed on the inner side of the cavity 451 through the spring. When the screening cylinder 42 rotates to the lower end, the hollow ring 453 is squeezed by gravity and centrifugal force. The hollow ring 453 compresses the spring and drives the annular contact piece 454 to move downward. When the movement occurs, the air in the cavity 451 away from one end of the screening cylinder 42 is squeezed, and the space in the other end of the cavity 451 suddenly increases. At this time, the squeezing force of the air inside the cavity 451 on the end of the fixed cylinder 45 close to the screening cylinder 42 is reduced, so that the fixation of the fixed cylinder 45 on the mineral particles becomes loose, and the annular contact piece 454 is fixedly installed on the outer surface of the hollow ring 453, and the outer surface of the annular contact piece 454 contacts the inner wall of the cavity 451.

[0030] The discharging mechanism 5 includes a discharging barrel 51, a fixed column 52 and a buffer 53. The discharging barrel 51 is fixedly mounted on the lower end of the base 1. The discharging barrel 51 is a triangular prism-shaped barrel. A discharging groove is arranged inside the discharging barrel 51, and the notch at the upper end of the discharging groove is larger than the notch at the lower end. The fixed column 52 is fixedly mounted in the inner discharging groove of the discharging barrel 51. The buffer 53 is arranged in the inner discharging groove of the discharging barrel 51. The buffer 53 includes an elastic plate 531, an elastic membrane 532 and a fixed ball 533. The elastic plate 531 is fixedly mounted on the outer surface of the fixed column 52. The lower end of the elastic plate 531 is connected to the lower end of the discharging barrel 51. The mineral particles are When the mineral particles fall, they come into contact with the elastic plate 531. At this time, the collision force generated by the mineral particles causes the elastic plate 531 to deform, and the air between the elastic plate 531 and the discharge barrel 51 is squeezed. The squeezed air forms resistance to slow down the deformation of the elastic plate 531, thereby reducing the falling speed of the mineral particles and preventing the mineral particles from colliding with the discharge barrel 51 and causing damage to the discharge barrel 51. The elastic membrane 532 is fixedly installed on the side of the elastic plate 531 close to the inner discharge groove of the discharge barrel 51. The elastic membrane 532 is connected to the inner discharge groove of the discharge barrel 51, and the fixed ball 533 is fixedly installed on the outer surface of the elastic membrane 532.

[0031] When in use, the base 1 is placed on a horizontal ground, and the rotating baffle 6 on the outside of the screening cylinder 42 is adjusted. The rotating baffle 6 blocks the through hole 43 when rotating. The screening accuracy of the screening cylinder 42 for mineral particles is adjusted by the blocking of the through hole 43 by the rotating baffle 6. The mineral particles are poured into the screening cylinder 42, and the switch of the motor 3 is turned on. The motor 3 works, and the output shaft of the motor 3 drives the screening cylinder 42 to rotate through the rotating shaft 41. When the screening cylinder 42 rotates, the elastic strip 441 on the inside of the screening cylinder 42 continuously moves the mineral particles to disperse the aggregated mineral particles, thereby avoiding the mineral particles from sticking to each other and affecting the screening efficiency of the device. When the screening cylinder 42 rotates, the mineral particles continuously move toward the through hole 43 and enter the fixed cylinder 45 inside the through hole 43. When the mineral particles are within the set size, , the mineral particles fall from the screening cylinder 42 through the fixed cylinder 45 and fall into the discharge cylinder 51. When the mineral particles fall, they contact the elastic plate 531. At this time, the collision force generated by the mineral particles causes the elastic plate 531 to deform, and the air between the elastic plate 531 and the discharge cylinder 51 is squeezed. The squeezed air forms a resistance to slow down the deformation of the elastic plate 531, thereby reducing the falling speed of the mineral particles and preventing the mineral particles from hitting the discharge cylinder 51 and causing damage to the discharge cylinder 51. When the air between the elastic plate 531 and the discharge cylinder 51 is squeezed, the elastic membrane 532 is deformed by force, and the fixed balls 533 on the elastic membrane 532 move accordingly. With the cooperation of the elastic membrane 532, the fixed balls 533 continue to move, thereby causing the elastic plate 531 to vibrate continuously, making the mineral particles more The spring 453 is quickly separated from the discharge cylinder 51 to prevent the mineral particles from staying on the elastic plate 531. When the larger-sized mineral particles are stuck in the fixed cylinder 45, the hollow ring 453 inside the cavity 451 continuously squeezes or stretches the spring as the screening cylinder 42 rotates. When the hollow ring 453 is active, the annular contact piece 454 is constantly in contact with the resistance ring 452. When the annular contact piece 454 passes through the resistance ring 452, the fixed cylinder 45 is deformed by force. The deformed fixed cylinder 45 squeezes the mineral particles inward, so that the fixed angle of the mineral particles changes. When the screening cylinder 42 rotates to the lower end, the hollow ring 453 is squeezed by gravity and centrifugal force. The spring is driven by the hollow ring 453 to move downward. When it moves, the air in the cavity 451 away from the end of the screening cylinder 42 is affected. When squeezed, the space at the other end of the cavity 451 suddenly increases. At this time, the squeezing force of the air inside the cavity 451 on the end of the fixed cylinder 45 close to the screening cylinder 42 is reduced, so that the fixation of the fixed cylinder 45 to the mineral particles becomes loose. At this time, the elastic strip 441 moves toward the through hole 43 driven by the counterweight ball 442, and the counterweight ball 442 generates a magnetic repulsive force on the hollow ring 453, which strengthens the squeezing of the hollow ring 453 on the spring, making the fixation of the fixed cylinder 45 to the mineral particles looser. The counterweight ball 442 moving toward the through hole 43 contacts the mineral particles. When the elastic strip 441 drives the counterweight ball 442 to return, the mineral particles are pushed to the outside of the fixed cylinder 45, which avoids the mineral particles being stuck in the through hole 43, causing the through hole 43 to be blocked, and affecting the screening efficiency of the device.
