[0033] Working principle:
[0034] As shown, Figures 1 to 6 the user turns on the power supply of the vibrating screening machine 1 and the power supply of the electric push rod 34 respectively, then the user guides the raw materials into the inside of the feed box 2, then the raw materials automatically slide into the inside of the vibrating screening machine 1 through the inclination of the feed box 2 itself, then the screening of the raw materials is completed through the working of the vibrating screening machine 1;
[0035] As shown, Figures 1 to 6As shown, when the raw materials are injected into the inside of the feeding box 2, the piston rod in the electric push rod 34 drives the connecting rod 35 to move up and down reciprocally, and the connecting rod 35 drives the piston block 36 to move up and down reciprocally when moving up and down reciprocally. Since the radius of the piston block 36 is matched with the inner diameter of the processing cylinder 32, the inside of the processing cylinder 32 is under negative pressure when the piston block 36 moves upward by using the negative pressure principle, so that the suction force is generated in the inside of the piston block 36. The suction force in the inside of the piston block 36 enters the inside of the guide-in box 37, so that the sealing disc 39 and the sealing block 313 are turned over, thereby the sealing disc 39 is released from the sealing of the communication between the guide-in pipe 310 and the guide-in box 37, and the sealing block 313 seals the communication between the guide-out box 312 and the processing cylinder 32, so that the suction force enters the inside of the guide-in pipe 310, and the suction force enters the inside of the M-shaped guide-in plate 311 through the guide-in pipe 310, thereby the suction force generates suction force through the guide-in hole on the M-shaped guide-in plate 311, so that the powdery raw materials flying in the inside of the feeding box 2 are sucked into the guide-in cavity of the M-shaped guide-in plate 311, and then enter the inside of the processing cylinder 32. The process is consistent with the above-mentioned suction force transmission process. When the piston block 36 moves downward, the piston block 36 turns over the sealing disc 39 again to the sealing position of the communication between the guide-in pipe 310 and the guide-in box 37 by using the air compression principle, and the sealing block 313 is turned over to the sealing position of the communication between the guide-out box 312 and the processing cylinder 32 by using the air compression principle. Figure 4 As shown, the communication between the guide-in pipe 310 and the guide-in box 37 is sealed, and the inside of the processing cylinder 32 is under pressure by moving the piston block 36 downward, so that the sealing block 313 is turned over to the sealing position of the communication between the guide-out box 312 and the processing cylinder 32. Figure 4 As shown, the communication between the processing cylinder 32 and the guide-out box 312 is opened, so that the powdery raw materials in the inside of the processing cylinder 32 are guided into the inside of the guide-out box 312. The powdery raw materials are guided into the inside of the guide-out pipe 315 from the inside of the guide-out box 312 under the action of the pressure, and then are guided into the inside of the vibrating screen separator 1 from the inside of the guide-out pipe 315, thereby the flying powdery raw materials are directly transported into the inside of the vibrating screen separator 1, so as to ensure the weight of the powdery raw materials after screening, and avoid the waste of the powdery raw materials. The process does not need manual operation, can prevent the workers from being polluted by the flying powdery raw materials, thereby is favorable for reducing the probability of the surrounding environment of the vibrating screen separator 1 being polluted. At the same time, the inside screen of the vibrating screen separator 1 is prevented from being blocked when the powdery raw materials are transported into the inside of the vibrating screen separator 1, thereby the excessive raw materials are prevented from being guided out with the impurities.
[0036] The M-shaped guide-in plate 311 is unique, which is favorable for expanding the contact area between the M-shaped guide-in plate 311 and the powdery raw materials, and the M-shaped guide-in plate 311 is more favorable for guiding the air flow in the inside of the feeding box 2, thereby is favorable for accelerating the collection speed of the powdery raw materials, and is favorable for reducing the powdery raw materials adsorbed on the outer surface of the M-shaped guide-in plate 311 in the collection process, so as to ensure the content of the powdery raw materials entering the inside of the vibrating screen separator 1.
[0037] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
