[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 9As shown, a screening device for bamboo charcoal processing comprises a screening box 1, a feeding hopper 4 is arranged on one side of the upper end of the screening box 1, a bottom discharge hopper 2 is fixedly arranged on the lower end of the screening box 1, a vibration motor 3 is fixedly arranged on the lower end of the bottom discharge hopper 2, a sealing door 5 is hingedly arranged on one side of the screening box 1 through a reset hinge, two rotating plates 6 are symmetrically arranged on the inner wall of the screening box 1, a torsion spring is arranged at the rotating connection between the two rotating plates 6 and the inner wall of the screening box 1, a plurality of sieve plates are arranged between the two rotating plates 6, and the plurality of sieve plates are distributed up and down, and the side walls of the screening box 1 are respectively penetrated with the sieve plates. The side discharge hopper 9, the two rotating plates 6 are respectively provided with connecting components for fixing the screen plates on opposite sides, and the inside of the screening box 1 is provided with a driving component for driving the sealing door 5 to open and driving the rotating plate 6 to deflect. When in use, the material is added to the screening box 1 from the feed hopper 4, and the screen plate is driven to vibrate when the vibration motor 3 is in the working state, so as to achieve the effect of screening the material, and the screen plates are distributed from top to bottom and the screen mesh aperture is gradually reduced, so as to achieve the effect of multi-stage screening of the material, and the material is discharged along the side discharge hopper 9 and the bottom discharge hopper 2 respectively;

[0036] The connecting assembly includes an end plate 27 arranged on the outer side of the rotating plate 6 and a slide groove 20 opened on the inner side of the rotating plate 6 for sliding connection of the screen plate. A clamping block 23 is connected to one side of the end plate 27 through a connecting spring 24. One end of the clamping block 23 movably penetrates into the slide groove 20 and has inclined surfaces on both sides. A clamping interface 19 matching the clamping block 23 is opened on the side wall of the screen plate. A guide rod 25 is fixedly provided at the other end of the clamping block 23. A guide hole 26 for the guide rod 25 to movably penetrate is opened on the surface of the end plate 27. Rectangular openings 14 for the guide rod 25 to extend are respectively opened on the side walls of the screening box 1. A closing piece for closing the rectangular opening 14 is provided on the outer side of the screening box 1. When in use, the staff can replace the screen plates with different screen mesh apertures according to the use requirements. When installing the screen plate (refer to the attached manual Figure 3 , Instruction Manual Figure 6 And the instruction manual Figure 7 ), the staff slides one end of the sieve plate from the slide groove 20. During this process, one end of the sieve plate will squeeze the clamping block 23, so that the connecting spring 24 is compressed, and one end of the guide rod 25 can extend into the rectangular opening 14. When the clamping interface 19 on one side of the sieve plate is aligned with the clamping block 23, the connecting spring 24 resets the clamping block 23 to snap into the clamping interface 19, and the sieve plate is initially limited and fixed. Since the clamping block 23 can still be squeezed under stress, the connecting spring 24 is compressed, that is, the sieve plate continues to be pushed inward or pulled outward, and the sieve plate can continue to slide along the slide groove 20. Through the above description, the sieve plate is installed and the initial limit fixation of the sieve plate is achieved.

[0037] Further, the driving assembly includes a rotating shaft 12 rotatably arranged inside the screening box 1 and a driving motor 13 fixedly arranged outside the screening box 1 for driving the rotating shaft 12 to rotate. An eccentric wheel 7 for squeezing the sealing door 5 to open is fixedly sleeved on the outer side of the rotating shaft 12. A pressure plate 10 matched with the eccentric wheel 7 is fixedly arranged on one side of one rotating plate 6. A limiting member matched with the eccentric wheel 7 for limiting the opening of the sealing door 5 is arranged on one side of the screening box 1. When in use, after the preliminary installation of the screen plate is completed, the staff starts the driving motor 13, and the driving motor 13 drives the rotating shaft 12 to rotate clockwise (refer to the attached manual). Figure 3 And the instruction manual Figure 5 ), the rotation of the rotating shaft 12 drives the eccentric wheel 7 to rotate, and the rotation of the eccentric wheel 7 gradually releases the extrusion limit on the sealing door 5. When the eccentric wheel 7 is separated from the sealing door 5, the sealing door 5 is automatically closed under the action of the reset hinge, and then the eccentric wheel 7 continues to rotate, gradually squeezing the pressure plate 10. The pressure plate 10 is squeezed and flipped downward, thereby driving the rotating plate 6 to rotate, so that the screen plate is inclined, which is convenient for the material to roll along the surface of the screen plate and improve the screening efficiency.

[0038] Further, the closure member includes a deflection plate 15 and a restraint cover 8 for closing the rectangular opening 14. The deflection plate 15 is hingedly matched with the outer side of the screening box 1 through a reset hinge. The restraint cover 8 is fixedly connected to the rotating shaft of the rotating plate 6 and the center lines are located on the same axis. The lower end of the restraint cover 8 is provided with a notch groove 32 for deflection of the deflection plate 15. In the initial state (i.e., when the screen plate is slidably installed, refer to the attached manual) Figure 3 ), at this time, the notch groove 32 and the deflection plate 15 are in an aligned state, and the deflection plate 15 can be deflected, that is, the clamping block 23 is squeezed so that one end of the guide rod 25 extends into the rectangular opening 14, which will cause the deflection plate 15 to deflect, and in the rotation process of the rotating plate 6 described in the previous paragraph, the rotation of the rotating plate 6 will drive the constraint cover 8 to rotate, so that the notch groove 32 and the deflection plate 15 are misaligned, thereby limiting the deflection of the deflection plate 15, and the deflection of the deflection plate 15 is constrained, that is, the rectangular opening 14 is in a closed state, at this time, one end of the guide rod 25 cannot extend into the rectangular opening 14, that is, the clamping block 23 cannot move under the condition of being squeezed, then the screen plate cannot slide at this time, that is, the stability of the screen plate after installation is guaranteed.

[0039] Further, the limiting member includes a fixed shell 28 fixedly arranged on the outer side of the screening box 1 and a movable plate 29 slidably arranged inside the fixed shell 28. A pressure block 11 cooperating with the eccentric wheel 7 is movably penetrated through the side wall of the screening box 1. One end of the pressure block 11 is fixedly connected to the movable plate 29. A limiting plate 31 is provided on one side of the movable plate 29 for limiting the opening of the sealing door 5. The other side of the movable plate 29 is connected to the inner wall of the fixed shell 28 through a compression spring 30. When in use, the rotating shaft 12 rotates clockwise to drive the eccentric wheel 7 to rotate. The eccentric wheel 7 will squeeze the pressure block 11, and the compression spring 30 is in a compressed state. As the eccentric wheel 7 continues to rotate to squeeze the pressure plate 10, that is, the sealing door 5 is already in a closed state, the eccentric wheel 7 will release the squeezing of the pressure block 11. At this time, under the resetting action of the compression spring 30, the movable plate 29 is driven to move, thereby making the limiting plate 31 block the outside of the sealing door 5, thereby achieving the effect of limiting and fixing the sealing door 5, and ensuring the stability of the sealing door 5 in the closed state.

[0040] Furthermore, the surfaces of the two rotating plates 6 are respectively provided with baffles 21 that cooperate with the sides of the sieve plate. The baffles 21 are made of rubber material. Under the action of the baffles 21, a gap between the sieve plate and the inner wall of the screening box 1 is avoided, which may easily cause material leakage.

[0041] Furthermore, the sieve plates are respectively a first sieve plate 16, a second sieve plate 17 and a third sieve plate 18, the sieve aperture of the first sieve plate 16 is larger than the sieve aperture of the second sieve plate 17, and the sieve aperture of the second sieve plate 17 is larger than the sieve aperture of the third sieve plate 18, so that the material passes through the first sieve plate 16, the second sieve plate 17 and the third sieve plate 18 in sequence for multi-stage screening, thereby improving the material screening effect.

[0042] Furthermore, an embedding groove 22 matching with the end plate 27 is provided on the outer side of the rotating plate 6, and the end plate 27 is fixedly connected to the inner wall of the embedding groove 22 by bolts, thereby ensuring the firmness of the installation of the end plate 27 and improving the aesthetics.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
