The extrusion mechanism 8 is acted by the impact frequency of the steel balls to adjust the setting height of the elastic baffle 6, so that the height of the elastic baffle 6 is automatically adjusted to only block the steel balls which are lifted higher by the action of centrifugal force.
The working principle is as follows: during operation, ore blocks to be processed enter the rotating cylinder 2 from the feeding hole at one end of the fixed end cover 3, processed ore particles are discharged outwards from the discharging hole at one end of the fixed end cover 3, and the feeding hole and the discharging hole are not marked in fig. 1;
the driving part 1 drives the rotating cylinder 2 to start rotating, the rotating cylinder 2 drives the steel balls and the ore blocks inside the rotating cylinder 2 to move in a parabolic form after rising for a certain height along the inner wall of the rotating cylinder 2 against gravity under the action of centrifugal force, so that different steel balls have different resistance from the ore blocks, the resistance action of individual steel balls is small, the rising height of the individual steel balls is higher than that of most of the steel balls, and the steel balls have higher rising height and larger hitting force on the ore blocks when falling to be in contact with the ore blocks, please refer to a steel ball movement track distribution diagram in fig. 3;
the initial position of the elastic baffle 6 is at a lower position, namely a position interfering with a parabolic track of most of the steel balls, when the rotating cylinder 2 rotates at a normal rotating speed, the motion track of most of the steel balls in the rotating cylinder is a determined value, so that the elastic baffle 6 gradually moves upwards to find a position through the extrusion frequency change of the steel balls on the extrusion ring 801, so that the motion track of most of the steel balls is not contacted with the elastic baffle 6, and only the steel balls with higher lifting height are contacted with the elastic baffle 6;
when a high-frequency steel ball impacts the extrusion ring 801 at the initial position, the extrusion ring 801, the first connecting rod 806 and the first piston ring 808 move inwards along the outer cylinder body 802, so that the oil stop block 810 moves forwards to stop the oil inlet 811, hydraulic oil in the oil tank flows in through the oil inlet 811, the oil inlet amount of the oil inlet 811 is larger than the fixed oil amount of the oil outlet 812, the hydraulic oil in the outer cylinder body 802 is in a full state, at the moment, the extrusion ring 801 moves to drive the second piston ring 809 to move outwards instantaneously, the second pressure spring 813 is compressed at the same time, so that the extrusion protrusion 805 moves outwards to extrude the lower end of the dial frame 902, the dial frame 902 deflects around the rotating pin 903, the upper end dial teeth of the dial frame 902 push the feed ratchet 901, the feed ratchet 901 rotates, so that the first rotating shaft 904 rotates through the meshing transmission of the first bevel gear 905 and the second bevel gear 906, the second intermediate shaft 907 rotates, and the third rotating shaft 1002 rotates through the meshing transmission of the first transmission gear 908 and the second transmission gear 1001, so that the lifting gear 1003 rotates to enable the driving shell 7 and the elastic baffle 6 to move upwards along the guide toothed plate 11;
only the steel ball with the higher ascending height contacts the elastic baffle 6 when the elastic baffle 6 moves upwards, the collision frequency of the steel ball and the extrusion ring 801 is reduced, so that hydraulic oil in the outer cylinder 802 is not filled with decoration, at the moment, the first piston ring 808 moves and cannot drive the second piston ring 809 to move outwards, the lifting gear 1003 cannot be driven to rotate, at the moment, the position of the elastic baffle 6 is kept fixed, at the moment, the elastic baffle 6 only blocks the individual steel ball with the higher ascending height, the phenomenon that the edge angle of the ore block is crushed into powder due to too large kinetic energy when the steel ball falls is avoided, the amount of powder in the processed ore material is reduced, and the loss in the processing process of the ore material is reduced;
after the processing is finished, the driving element 1 stops working, the electromagnet 1008 loses the electromagnetic property and disappears, so the electromagnet 1008 does not repel the magnet plate 1008, the pawl 1005 retreats under the reset action of the connecting spring 1006, at this time, the elastic baffle 6 and the driving shell 7 reset and move to the initial position under the action of gravity, and the lower end of the guide toothed plate 11 is provided with a limit stop strip, which is explained here.
In summary, the following steps: through setting up elastic baffle, extrusion mechanism, intermediate mechanism, hoist mechanism and guide rack, make hoist mechanism drive elastic baffle according to the frequency that the steel ball struck on the extrusion mechanism and move up to elastic baffle 6 and only hinder the higher steel ball that rises individually, kinetic energy is too big when avoiding the steel ball whereabouts and causes and smash the ore block limit angle and become powdered to the powder in the ore material that makes the processing back obtain still less, reduced the loss in the ore material course of working.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
