Description

[0001] The utility model relates to the technical field of screening, in particular to a screening machine component. Background technology:

[0002] At present, a large amount of coal gangue is produced in the coal sorting industry. Among them, the fine-grained gangue with a particle size concentrated between 0.25mm and 0.5mm and a calorific value of about 900 to 1000 kcal still has potential utilization value. A screening machine is needed to screen out the gangue particles that meet the requirements for reuse.

[0003] The sieve plate in the existing screening machine is fixed in the screening machine cavity by bolts. After long-term use of the sieve plate, gangue particles will be blocked in the sieve holes of the sieve plate and affect the material falling. The staff needs to enter the screening machine and clean the sieve holes from the bottom of the sieve plate through a cone rod, which is very dangerous. Alternatively, the staff can unscrew multiple bolts and then disassemble the sieve plate from the feeding end of the screening machine for cleaning. The disassembled sieve plate can easily be deformed if not carefully cleaned, which makes it inconvenient to install the sieve plate. Utility model content:
