[0043] The modular frame 4 comprises a frame body 1 4.1 and a frame body 2 4.2 which are arranged in the longitudinal direction and are clamped together. A plurality of modular frames 4 are clamped in the groove structure of the inner peripheral wall of the modular outer frame 3. The top surfaces of the frame bodies 1 4.1 and the frame bodies 2 4.2 are respectively detachably sleeved with a plurality of mushroom-shaped connectors 4.3; wherein, a notch 1 4.1.2 is provided on one side of the frame body 1 4.1, a notch 2 4.2.2 is provided on one side of the frame body 2 4.2 and a clamping head 4.2.3 which is respectively clamped and matched with the notch 1 4.1.2 and the notch 2 4.2.2 is provided on the other side.

In addition, the frame 1 4.1 and the frame 2 4.2 respectively include a rectangular frame, partitions evenly arranged in the inner cavity of the rectangular frame, and a lattice structure arranged between the partitions and between the partitions and the rectangular frame, and the threaded sleeve 1 4.1.1 and the threaded sleeve 2 4.2.1 are respectively arranged in the middle of the partition.

[0044] A T-shaped sliding groove 5.1 is provided at the bottom of the screen plate 5 in the horizontal direction and is slidably engaged with the mushroom head 4.3.1 in the horizontal direction.

[0045] In addition, the clamping member 2, the U-shaped end frame 3.1, the side beam 3.2, the frame body 1 4.1, the frame body 2 4.2 and the screen plate 5 are respectively integrally cast by polyurethane. The polyurethane has a certain elasticity, so that the wedge strip 1 3.1.2 and the wedge strip 2 3.2.2 can be bent inwards at a certain angle at the side groove 1 3.1.4 and the side groove 2 3.2.4 respectively, that is, the setting of the side groove 1 3.1.4 and the side groove 2 3.2.4 is not only convenient for clamping with the top end of the T-shaped clamping member 2.2, but also reduces the thickness of the connection between the wedge strip 1 3.1.2 and the U-shaped member 3.1.1 and between the wedge strip 2 3.2.2 and the beam body 3.2.1, so that the wedge strip can be bent at a certain angle at this weak point.

[0046] In summary, when assembling the screen, first use bolts to fix the end plates 1.1 at both ends of the support member 1 to the inner wall of the vibrating screen box. Then use hexagon socket bolts to fix the slats 2.1 to the crossbeam 1.2 to complete the assembly connection between the clamping member 2 and the support member 1.

[0047] The mushroom-shaped connector 4.3 is installed by sleeve connection between the screw rod 4.3.2 and the threaded sleeve 1 4.1.1 and the threaded sleeve 2 4.2.1. The frame 2 4.2 is clamped to the frame 1 4.1 by the clamping relationship between the clamp head 4.2.3 and the slot 1 4.1.2, and then the multiple frame 2 4.2s are clamped to each other by the clamping relationship between the clamp head 4.2.3 and the slot 2 4.2.2 to form a group of combined frames 4; the multiple screens 5 are assembled on the top surface of the combined frame 4 by the clamping relationship between the T-shaped slide groove 5.1 and the mushroom head 4.3.1.

[0048] When assembling the combined outer frame 3, first insert multiple side beams 3.2 in sequence at the two ends of one of the U-shaped end frames 3.1. At this time, the combined outer frame 3 is not sealed. The assembly of the screen plate 5 and the combined frame 4 is inserted into the card slot 3.2.3, and the first assembly of the screen plate 5 and the combined frame 4 is pushed to be engaged with the U-shaped groove 3.1.3 of the first U-shaped end frame 3.1. After completing the installation of the assembly of the screen plate 5 and the combined frame 4, install another U-shaped end frame 3.1 to form a screening structure assembly.

[0049] The installation spacing of multiple support members 1 should meet the clamping dimensions of the T-shaped clamp 2.2 and the wedge strip 1 3.1.2 and the wedge strip 2 3.2.2. Align the wedge strip 1 3.1.2 and the wedge strip 2 3.2.2 at the bottom of the screening structure assembly and clamp them on the top of the two adjacent T-shaped clamps 2.2. And so on, until the installation of the entire screen is completed.

[0050] When it is necessary to replace the screen plate 5 and other components, it is necessary to remove the corresponding screening structure assembly from the T-shaped clamp 2.2. The specific operation is to push and bend the bottom wedge strip 1 3.1.2 and the wedge strip 2 3.2.2 toward the middle direction at a certain angle, so that one end of the screening structure assembly can be tilted upward, thereby facilitating the removal of the entire screening structure assembly. Then, the U-shaped end frame 3.1 at one end can be removed to take out the corresponding component for replacement.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
