NOVELTY - Dust-free type straw pressure molding production line comprises a feeding conveyor (1), a cutter (2), a scrap conveyor (3), a grading sieve (4), a material storage integrated unit (5), a straw feeding unit, a straw briquetting unit and a finished product assembly. The finished product assembly is equipped with finished goods warehouse. The finished goods warehouse in an inclination through finished product conveyor is connected to straw briquetting unit outlet. The finished goods warehouse is mounted on buffer hopper, automatic packaging scale and outlet of warehouse conveyor.    USE - Used as a dust-free type straw pressure molding production line.    ADVANTAGE - The production line: utilizes reasonable configuration of knife roller type cutter and pulse bag filter, thus it controls dust, purifies dust and improves the production; and provides assembly line production and has high efficiency and low labor intensity.    DETAILED DESCRIPTION - Dust-free type straw pressure molding production line comprises a feeding conveyor (1), a cutter (2), a scrap conveyor (3), a grading sieve (4), a material storage integrated unit (5), a straw feeding unit, a straw briquetting unit and a finished product assembly connected orderly. The finished product assembly is equipped with the finished goods warehouse. The finished goods warehouse in an inclination through a finished product conveyor is connected to the outlet of the straw briquetting unit. The finished goods warehouse is orderly mounted on the buffer hopper, automatic packaging scale and outlet of a warehouse conveyor. The cutter is a roller-type cutter with a cutting length of 30-50 mm. The material storage integrated unit with an air blower is connected to the outlet of the grading screen. The air blower outlet is connected to the material storage unit via upper part of cyclone dust collector and a bag filter. The material storage unit and bag filter are mutually connected and together constitutes a fixed dust purifying structure. The material storage unit of the horizontal spiral conveyor is connected to the lower end of a recycling conveyor. The recycling conveyor is located on the inlet of the straw feeding unit. The feeding port of straw briquetting unit is located in the straw feeding unit under the outlet of the automatic feeding mechanism.
