Before use, the vibration screen mesh can be placed in a required place to achieve the working operating conditions. It has a variety of usage methods to screen materials. In addition, the elastic clamping tube clamp 24 of the movable plate 1 20 is docked with the corresponding two bottom rods 19, and then the threaded rod 21 is rotated to make the elastic clamping tube clamp 24 of the movable plate 22 complete docking with the other two bottom rods 19, so that the connecting assembly completes the linkage of the screen frame 1 16 and the screen frame 2 18 to make them a whole. Figure 1 This is the initial state of the vibrating screen, that is, the isolation structure 9 is installed on the main frame 3 and separates the inner side of the main frame 3; Usage mode 1: When the same material needs to be screened into different grades, in the initial state of the vibrating screen, that is, the partition 45 is installed on the bottom plate 2 44 through the screw 3 46, the partition 45 divides the interior of the main frame 3 into two separate spaces, and then a collecting device is set below the main frame 3, and a baffle is set in the middle of the collecting device to divide the interior of the collecting device into two independent spaces to avoid confusion after the materials are screened. The same material is put into the two spaces of the main frame 3 for screening, and the vibrator 6 is started so that the main frame 3 is between the vibrator 6 and Under the action of spring 15, the hollow plate 4 moves up and down outside the guide rod 2, and at the same time, the motor 29 is started to make the turntable 30 act on the connecting arm 31 to move, and the connecting arm 31 acts on the bottom plate 32 to move up and down. The bottom plate 32 acts on the slider 33 through the connecting arm 235 to slide toward the middle of the slide block 25 to compress the spring 234. When the bottom plate 32 moves upward, the soft roller 38 will act on the corresponding screen frame 16 and the screen frame 218 to move upward, so that the screen frame 16 and the screen frame 218 are higher than the storage frame 10. At this time, the sides of the screen frame 16 and the screen frame 2 18 leak out, which can speed up the screening speed of the material inside the main frame 3. The soft roller 38 will act on the spring 39 under pressure to compress the storage plate 37 to move downward toward the inner bottom surface of the base 36. Under the action of the vibrator 6 and the motor 1 29, the screen 12, the screen 2 13, the screen frame 16 and the screen frame 2 18 are in contact with the soft roller 38 and hit by them, so as to avoid the accumulation of materials in one place and cause blockage. The soft roller 38 and the spring 39 can reduce the contact surface caused by being hit. Damage, start the second motor 42 to make it act on the bidirectional screw 40 to rotate forward and reverse within the preset range, so that the corresponding slider 2 43 slides back and forth outside the bidirectional screw 40 and the slide bar 41 with two sets of knocking structures 8, so as to avoid the soft roller 38 from being fixed in the striking surface position that contacts the screen 1 12, the screen 2 13, the screen frame 1 16 and the screen frame 2 18 each time, which affects its service life, and finally achieves the purpose that the material screened in the space on one side of the screen 12 and the screen frame 1 16 is larger than the material screened in the space on the one side of the screen 2 13 and the screen frame 2 18; Usage mode 2: When different materials need to be poured into the main frame 3 and separated for screening with the same aperture, under the conditions of usage mode 1, the corresponding positions on the storage frame 10 inside the main frame 3 are all replaced with screen 12, screen frame 16 or all replaced with screen 2 13, screen frame 2 18, and then the materials are poured in for screening; Usage method three: when it is necessary to pour the same material into the main frame 3 for uniform screening without separation, under the condition of usage method one, remove screw three 46, and then install the partition 45 to the corresponding position of the bottom plate three 47 through screw three 46, so that the inside of the main frame 3 is unobstructed, and then place the collecting device under the main frame 3 without partition in the middle of the collecting device, replace the corresponding positions on the storage frame 10 inside the main frame 3 with screen one 12, screen frame one 16 or all replace them with screen two 13, screen frame two 18, and then pour the material for screening.
