The driving mechanism 3 is configured such that when the coal gangue blanking amount on the screen frame 21 reaches a preset peak value, the rotating speed of the driving mechanism 3 reaches a preset maximum value, and the driving mechanism 3 drives the right side fixing plate 13 and the screen 211, and both the frequency and the moving amplitude of the vibration reach the maximum value.

In the present embodiment, the drive mechanism 3 includes a drive motor 31, a turntable 32, and an eccentric member 33. The driving motor 31 is fixedly disposed on the base 11. The turntable 32 is arranged above the driving motor 31 and is connected with the driving motor 31 through an eccentric part 33; the rotary disc 32 is always in contact with the right fixing plate 13; the turntable 32 is also provided with a moving groove 34; the eccentric member 33 is slidably provided to the moving groove 34; and is connected with the output shaft of the driving motor 31, so that the higher the rotation speed of the driving motor 31, the larger the movement amount of the eccentric member 33, and thus the larger the amplitude of the movement of the right fixing plate 13, the larger the vibration frequency.

With such arrangement, the driving motor 31 drives the eccentric part 33 to rotate, and then the rotating disc 32 is driven to rotate in the eccentric wheel manner under the movement of the eccentric part 33, so that the higher the rotation speed of the driving motor 31 is, the larger the movement amount of the eccentric part 33 is, and further, in the rotating process, the larger the rotating area covered by the rotating disc 32 is (the larger the radius is), and further, the larger the amplitude of the rotating disc 32 driving the right fixing plate 13 to move is, and the larger the vibration frequency of the right fixing plate 13 of the pile foundation of the rotating disc 32 is; further speaking, the vibration to the screen 211 and the guide plate 61 is the bigger, the larger the amplitude of the screen 211 moving up and down is, the frequency of the vibration and the shaking of the screen 211 is increased, and the stronger screening effect to the coal gangue material is formed.

In the present embodiment, the eccentric member 33 includes a square bushing 35, a motor shaft hole 36, a stopper post 37, and a pressure spring 38. The square bushing 35 is square and slidably disposed in the moving groove 34. The motor shaft hole 36 is disposed at the center of the square shaft sleeve 35, and is used for fixedly connecting the output shaft of the driving motor 31 and keeping the two rotating synchronously. The two limiting columns 37 are symmetrically distributed and are respectively arranged on the left side wall and the right side wall of the square shaft sleeve 35; the inner side wall of the movable groove 34 is also provided with a groove matched with the limit column 37 to slide; the guide and limit functions are achieved. One end of the compression spring 38 is arranged on the inner wall of the moving groove 34, and the other end of the compression spring is connected with the square shaft sleeve 35, so that the amount of the compression spring 38 moved by the square shaft sleeve 35 is different under different rotating speeds of the driving motor 31.

The purpose that so sets up is, driving motor 31 rigidity, through setting up eccentric part 33, can drive square shaft sleeve 35 and remove in shift chute 34, and then form the eccentric structure of carousel 32, the distance that square shaft sleeve 35 compression pressure spring 38 removed is big more, square shaft sleeve 35 eccentric position is big more, and then the promotion range to right side fixed plate 13 is big more, the promotion effect to right side fixed plate 13 has been guaranteed, and then realized reciprocating of screen cloth 211, play the effect to gangue material vibrations or upturning, and then improved the device intelligent sorting effect to the gangue on frequency of vibration and range simultaneously.

The working process is as follows:

in the initial state, the baffle 15 is in the original length, and the distance between the upright post 12 and the moving post 14 is the largest at the moment; under the state that the driving motor 31 is not started, the square shaft sleeve 35 is coaxial with the output shaft of the driving motor 31 and the turntable 32; the compression spring 38 is in its original length.

The worker starts the driving motor 31, and then the driving motor 31 starts to rotate; under different rotating speeds of the driving motor 31, the amount of the lower shaft sleeve 35 moving to compress the compression spring 38 is also different; that is, the lower the rotation speed of the driving motor 31, the smaller the amount of the square shaft sleeve 35 moving to compress the compression spring 38 due to the centrifugal force during rotation, and at this time, the rotating disk 32 is in an eccentric cam structure, and then, the amplitude of the right fixing plate 13 pushed by the rotating disk 32 is reduced, and the frequency is also lower.

At this time, the coal gangue is mainly fed, and the coal gangue falls into the right side of the uppermost screen 211, namely, the higher side of the screen 211. Then under the slope structure basis, the right side fixed plate 13 of deuterogamying drives the removal structure 22 on the removal post 14 and shakes from top to bottom, and then can make the articulated department of screen frame 21 and water conservancy diversion frame 23 reciprocate, plays screen cloth 211 to the turning up of gangue, vibrations effect, compares in the simple vibrations of tradition, more has the practicality, prevents the phenomenon that screen cloth 211 mesh blockked up.

And then under the screening operation of the coal gangue material at the screen 211 at the top, the coal gangue with large particle size is left, and the rest coal gangue material can fall through the meshes. Furthermore, the coal gangue left with large particle size can slide downwards under the continuous vibration operation, is discharged from the discharge port 17 corresponding to the upper part, and is transmitted and concentrated and recovered through an external conveyor belt. Meanwhile, the coal gangue materials falling from the uppermost screen 211 can slide down from the sorting port 231 of the sorting system at the next stage through the guide plate 61 to enter the sorting system at the next stage.

Then, the gangue material can be under the continuation of screen cloth 211 adjacent below to the screening operation, accomplish the intelligence of centering particle size gangue and select separately to discharge from the discharge gate 17 at middle part, and then transmit and concentrate the recovery through external conveyer belt. Meanwhile, the coal gangue materials with small particle diameters fall through the screen 211 in the secondary sorting system, and then downwards along the guide plate 61 at the current stage are sorted in the supporting plate 24, and are subjected to concentrated recycling processing through the discharge port 17 at the lower part, and then are transmitted and concentrated for recycling through the external conveyor belt. In this sorting process, driving motor 31 drives carousel 32 and rotates, and then continuously drives right side fixed plate 13 and controls reciprocating motion, and then realizes the vibrations from top to bottom of screen cloth 211 and guide plate 61, accelerates the screening operation of gangue.

When the gangue blanking amount on the screen frame 21 reaches the preset peak value, that is, the gangue feeding amount is large, the rotating speed of the operator accelerating the driving mechanism 3 reaches the maximum value, the most obvious change at this time is that the driving motor 31 rotates at a high speed to drive the square shaft sleeve 35 to rotate at a high speed synchronously, under the action of a strong centrifugal force, the amount of the square shaft sleeve 35 moving along the moving groove 34 to compress the compression spring 38 reaches the maximum value, that is, the turntable 32 at this time forms an eccentric structure with the maximum deflection radius.

The rotating disc 32 can push the right fixing plate 13 to reciprocate left and right to reach the maximum value, and the left and right movement frequency of the right fixing plate 13 is accelerated to the maximum value; at this time, the moving structure 22 on the moving column 14 is vibrated at a high frequency by the high-frequency and high-amplitude left and right movement of the right fixing plate 13, and the high-amplitude up and down movement is realized. Therefore, the vibration frequency and the movement amplitude of the screen 211 and the guide plate 61 reach the maximum value, and the screening operation of the coal gangue on the screen 211 is accelerated. Finally, the aim of intelligently sorting the coal gangue by the device is fulfilled.

Example 2: on the basis of the embodiment 1, the discharge port 17 is further provided with a plugging plate 18 capable of sliding left and right, so that the screen 211 completes plugging of the discharge port 17 during the coal gangue screening operation. The discharge port 17 is also provided with a guide plate 19 which is obliquely distributed in a left-low and right-high way. The purpose that so sets up is, when the coal gangue material got into this intelligence sorting unit from the right side of top screen cloth 211, because the setting of top screen cloth 211 slope structure, at the in-process that 13 removal of right side fixed plate drove the vibrations of screen cloth 211, can drive the screen cloth vibrations to make the material on the screen cloth to turn up, there may be some coal gangue materials not through multistage screening, and direct discharge gate 17 discharge from the screen cloth frame correspondence of top, lead to sorting the not good problem of effect. In order to solve the problem, the plugging plate 18 capable of moving left and right is arranged, after the upper-stage separation system carries out vibration screening for preset time, the external air pump drives the plugging plate 18 to be automatically opened, and intelligent separation and collection of coal gangue with different particle sizes are realized step by step; and the lower sorting system, so on.

Example 3: on the basis of embodiment 2, the shutter 15 includes a first plate 151, a second plate 152, and a spring 153. The left side of the first plate 151 is fixedly connected with the upright 12, and the right side is provided with a telescopic groove 154. The right end of the second plate 152 is inserted into the movable column 14, and the left end is inserted into the telescopic slot 154. The springs 153 are uniformly distributed, and one end of each spring 153 is fixedly connected with the inner wall of the telescopic slot 154, and the other end is fixedly connected with the second plate 152. And the initial state is maintained, the spring 153 is at the original length, and the distance between the upright post 12 and the moving post 14 is the largest. The arrangement aims at firstly ensuring that the coal gangue feeding can only be screened step by step through a sorting system to prevent the coal gangue from spilling because the baffle 15 is contacted with the side walls of the screen frame 21 and the flow guide frame 23; secondly, the distance between the upright post 12 and the movable post 14 is constantly changed, and in order to match the movement of the movable post 14, the baffle 15 is arranged to be a telescopic structure, so that the stability of the device for intelligently sorting coal gangue is improved.
