[0014] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiment 1

[0015] As Figs. 1-2The utility model discloses a screening equipment dust falling mechanism, adopt the technical scheme, including sieve machine 1, cyclone collector and storage jar, sieve machine 1 includes feed inlet 101 and discharge gate 102, feed inlet 101 connects cyclone collector, and the interface is sealed through sealing washer, and discharge gate 102 connects storage jar, and the discharge gate 102 is connected with the storage jar through the flexible element 7, and the flexible element 7 includes canvas, and there is hoop and sealed joint on both sides of canvas, and the flexible element 7 is connected with discharge gate 102 through the hoop one end, and the other end is connected with storage jar, prevents sieve machine 1 vibration and interferes with storage jar, and there is draught fan 4 between feed inlet 101 and cyclone collector, and draught fan 4 is communicated with cyclone collector through the blanking pipe 2, and the interface is sealed through sealing washer, and there is dust falling pipe 3 between draught fan 4 and feed inlet 101, and there is dust falling piece 301 in dust falling pipe 3, and dust falling piece 301 is V-shaped structure, and the opening is towards sieve machine 1 direction, and dust falling piece 301 has multiple groups, and is arranged in dust falling pipe 3 internally in annular array and staggered, and the diameter of dust falling pipe 3 is greater than the diameter of blanking pipe 4 drop gate, and the transverse length of dust falling piece 301 is equal to the difference between dust falling pipe 3 and blanking pipe 4 drop gate radius, when feeding, material moves from top to bottom, when material contacts dust falling piece 301, material will slide to both sides of dust falling piece 301, so that it does not affect entering the inside of sieve machine 1, and the side of dust falling pipe 3 is equipped with air guide pipe 5, and air guide pipe 5 is communicated with the inside of dust falling pipe 3, and the other end of air guide pipe 5 has breather valve 6, when the internal pressure of dust falling pipe 3 is too small, breather valve 6 will supplement air to the inside, when the internal pressure is too big, will exhaust and will filter the internal material, prevent material leakage, and dust falling pipe 3 and feed inlet 101 are connected through flexible element 7, and the flexible element 7 includes canvas, and there is hoop on both sides of canvas, and the flexible element 7 is connected with dust falling pipe 3 through the hoop one end, and the other end is connected with feed inlet 101.
