Description

Technical Field

[0001] The utility model relates to the technical field of high square screens, in particular to a high square screen convenient for replacing a lead screw. Background Technique

[0002] The working principle of a high square screen is to make the material move relatively on the screen surface through vibration, so as to achieve the purpose of screening. Sieve meshes are installed in the multi-layer sieve grids of the high square screen, and the aperture size of the sieve mesh is selected according to the needs of the material. Therefore, the sieve grids need to be frequently increased, decreased and replaced. Because of this, the lead screw responsible for locking the sieve grids is relatively easy to break.

The upper locking nut is blocked by the frame and the side plate, and the working space is relatively closed. If the lead screw breaks, the side plate at the lead screw position needs to be integrally removed for replacement. Moreover, the lead screw is prone to rotate during disassembly and assembly, and two wrenches are required to complete the work. Two workers need to work together for more than 30 minutes, and it usually takes about 45 minutes to complete the replacement of the lead screw, resulting in low work efficiency.
