Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

A novel anti-blocking cyclone sieve comprises a support 1, a box body 2, a motor 3, a feeding port 4, a fine discharging port 5, a coarse discharging port 6, a feeding auger 7, a screen and a sieve plate, wherein the box body 2 is fixed above the support 1, the motor 3 is fixed on the left side of the support 1, the feeding port 4 is fixed on the box body 2 and is positioned above the feeding auger 7, the feeding auger 7 and the sieve plate are fixed on a rotating shaft 8, two ends of the rotating shaft 8 are fixed inside the box body 2 through bearings 9, the motor 3 pulls the bearings 9 to rotate through a belt 15, the fine discharging port 5 is positioned below the box body 2, the coarse discharging port 6 is positioned on the right side of the box body 2, the screen is positioned on the inner wall of the box body 2, the sieve plate comprises a plurality of flat 5 plates 10 and spiral plates 11 which are distributed at intervals, the flat plates 10 and the spiral plates 11 are fixed, an air permeable cap 14 is fixed above the pressure relief opening. Because the end part of the brush 13 is of a non-flat structure and has certain elasticity, the screen mesh is ensured to be cleaned while filtering, and blockage is prevented; when the cyclone sieve runs, airflow vortex is formed in the closed box body by stirring of the sieve plate, when particles are output from the fine discharge port 5, airflow can flow out from the fine discharge port 5 along with fine wood powder 10, at the moment, the air holes in the upper end of the box body 2 can form convection with the fine discharge port 5, the pressure of the airflow which originally flows out from the fine discharge port 5 is released, the material of the fine discharge port 5 can move in a free falling mode and fall into a discharge bin, the influence of the airflow is avoided in the falling process of the wood powder, and the phenomena that the wood powder splashes and flies and blocks a screen mesh cannot occur; the ventilation cap 14 is fixed on the box body 2 through screws, so that the disassembly and maintenance are convenient.
