[0024] The screening device 7 includes a screening and conveying housing 71. A support mounting plate 72 is fixed on the outer side of the screening and conveying housing 71. A blanking port is opened at the top of the screening and conveying housing 71. A discharge port is opened at the bottom of the screening and conveying housing 71. A servo motor 73 is installed on the top of the support mounting plate 72. A spiral conveying shaft 79 is fixed on the outer side of the output shaft of the servo motor 73. A fixed connecting plate 74 is fixed at the top of the screening and conveying housing 71. An installation connecting plate 78 is fixed at the top of the screening and conveying housing 71. An installation connecting groove 710 is opened inside the installation connecting plate 78. A screening connecting plate 75 that penetrates through the other side is movably inserted into one side of the installation connecting plate 78. One end of the screening connecting plate 75 is fixed with an installation limit pad 76. A metal handle 77 is installed on the outer side of the installation limit pad 76. A closing device 8 is arranged at the bottom of the installation limit pad 76. The size of the installation connecting groove 710 is adapted to the size of the screening connecting plate 75. The screening and conveying housing 71 and the support connecting legs 5 are fixedly connected.

[0025] During the use of this device, when crushing, the pulp to be crushed is sent into the crusher housing 1 through the feed inlet 3. Then, the driving motor 2 is started, and the crushing blade 4 is driven by the output shaft of the driving motor 2 to crush the material. The crushed material can fall into the screening connecting plate 75, and the crushed material is screened through the screening connecting plate 75. The crushed material with qualified size after screening can fall into the screening and conveying housing 71. Then, the servo motor 73 at the top of the support mounting plate 72 is started, and the spiral conveying shaft 79 is driven to rotate by the output shaft of the servo motor 73. The crushed material with qualified size after crushing and screening is conveyed through the spiral conveying shaft 79. A discharge port is opened on one side of the bottom of the screening and conveying housing 71. A receiving container can be placed at the bottom of the discharge port to centrally collect the crushed material with qualified size after crushing and screening. At the same time, the crushed material with larger size after crushing and screening is collected through the screening connecting plate 75. The user can pull the metal handle 77 to drive the installation limit pad 76 and the screening connecting plate 75 to move, so as to take out the screening connecting plate 75 and the crushed material.

[0026] Please refer to Figure 1 and Figure 4, the present utility model provides a pulp crushing device with a screening function. The closing device 8 includes a fixed mounting block 81.

[0027] During the use of this device, when the screening connecting plate 75 on one side of the mounting limit pad 76 is inserted and installed, the corresponding surface of the mounting limit pad 76 is attached to the outside of the mounting connecting plate 78. At this time, the corresponding surface of the fixed mounting block 81 at the bottom of the mounting limit pad 76 is also attached to the outside of the mounting connecting plate 78. Then, the guiding slider 87 can be toggled to make the guiding slider 87 slide in the chute provided in the guiding mounting sleeve 86, and the guiding slider 87 drives the moving connecting plate 88 to move simultaneously, so that the moving connecting plate 88 penetrates through the limit mounting sleeve 85. The moving connecting plate 88 is simultaneously movably sleeved outside the metal threaded column 83. Finally, the connection threaded sleeve 84 is threadedly connected with the metal threaded column 83, and the corresponding surface of the connection threaded sleeve 84 is attached to the corresponding surface of the moving connecting plate 88, which can conveniently complete the fixation of the position of the moving connecting plate 88 and ensure that the fixed mounting block 81 and the mounting limit pad 76 are closely attached to the mounting connecting plate 78, ensuring the installation and screening stability of the screening connecting plate 75. When it is necessary to release the fixation, only the connection threaded sleeve 84 outside the metal threaded column 83 needs to be unscrewed, and then the guiding slider 87 is pulled horizontally to remove the shielding of the moving connecting plate 88 from the outside of the fixed mounting block 81.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
