Novel sieve plate with adjustable sieve pores

The utility model discloses a novel sieve plate with adjustable sieve meshes, which relates to the technical field of sieve plates and comprises fixed plates, an upper sieve plate net and a lower sieve plate net, lower sieve meshes are uniformly arranged on the lower sieve plate net, the fixed plates are symmetrically arranged at the left end and the right end of the lower sieve plate net, and a groove is arranged on one side of each fixed plate. The screening device has the beneficial effects that through the ingenious design of a first adjusting device, a worker can move a lower screening plate net left and right by screwing a first bolt, so that the relative positions of lower screening holes in the lower screening plate net and upper screening holes in an upper screening plate net can be changed, and the sizes of the screening holes are adjusted; through the design of a second adjusting device, a worker can move the upper sieve plate net back and forth by screwing a second bolt, so that the relative posit
