Technical Field

[0001] The utility model relates to the technical field of sand and gravel screening, in particular to sand and gravel screening equipment. Background Art

[0002] Sand and gravel refers to a loose mixture of sand particles and crushed stone. In geology, mineral or rock particles with a particle size of 0.074 to 2 mm are called sand, and those with a particle size greater than 2 mm are called gravel or angular gravel. If the crushed stone in the sand and gravel is mostly gravel, it can be called sand and gravel. When screening sand and gravel, screening equipment is required for screening.

[0003] After searching, the announcement number is CN214183962U, and the name is a utility model of a sand and gravel screening machine, which includes a box body fixed on a bracket. Through research and analysis, it is found that although it is convenient to adjust the inclination angle of the drum for material discharge, it still has the following disadvantages to a certain extent.

[0004] For example, due to insufficient screening of sand and gravel during use, it does not have the screening function, so it cannot perform multiple screenings on sand and gravel, and cannot screen gravel of different sizes, which reduces the screening effect of sand and gravel. Moreover, the sand and gravel cannot be moved during screening, and it does not have the function of moving to prevent blocking, which affects the screening speed of sand and gravel, and easily causes sand and gravel to block the drum, reducing the screening efficiency. In order to solve the above technical problems, we have designed a sand and gravel screening equipment. Utility Model Content

By setting the support ring 8, the screening mesh cylinder 404 can be supported. When the gear 402 drives the gear ring 403 to rotate, the screening mesh cylinder 404 can rotate. The surface of the support ring 8 is penetrated with the screening mesh cylinder 404. The right end of the screening mesh cylinder 404 penetrates to the right side of the shell 1. The connection between the screening mesh cylinder 404, the support ring 8 and the shell 1 is movably connected through a bearing.
