The ejector tube 3 is provided with a negative pressure adsorption port 36, when air in the ejector tube 3 flows, negative pressure is formed at the negative pressure adsorption port 36, so that the negative pressure adsorption port 36 can suck light objects in undersize on the horizontal conveying line 8 into the ejector tube 3, and the principle of the cyclone catcher 4 is similar to that of a cyclone dust collector tower along with air flow in the ejector tube 3, so that the sucked light objects move downwards along the inner walls of the cylindrical barrel 41 and the circular truncated cone barrel 42 after entering the cyclone catcher 4, and finally fall out from the lower end of the circular truncated cone barrel 42, separation and trapping of light objects in the undersize are completed, and the trapping refers to that the light objects enter the cyclone catcher 4 after separation. In addition, in the invention, the air inlet end of the turbine type high-pressure fan 1 is communicated with the cylindrical air outlet pipe 5 through the circulating air inlet pipe 2, namely, the turbine type high-pressure fan generates suction force to the interior of the cyclone catcher 4, so that the pressure rise in the cyclone catcher 4 is avoided, the negative pressure adsorption effect at the negative pressure adsorption port 36 is ensured, and in such a communication mode, a circulating air flow is formed among the circulating air inlet pipe 2, the turbine type high-pressure fan 1, the jet pipe 3 and the cyclone catcher 4, so that under the condition that the turbine type high-pressure fan 1 with the same power is used, the jet pipe 3 has larger pressure, and the adsorption effect of the negative pressure adsorption port 36 is further improved.

By arranging the material collecting box 6, the air flow escaping from the lower end of the circular truncated cone barrel 42 is always trapped in the material collecting box 6, and finally the air flow escaping from the material collecting box 6 is balanced with the ascending air flow, so that the light materials falling from the material falling port 61 can be discharged stably, and the light materials are prevented from being blown away during discharging. Specifically, the collection box 6 is cylindrical, and the diameter of the collection box 6 is larger than the diameter of the lower end of the circular truncated cone cylinder 42.
