The brush-roller type safflower harvester according to claim 6, characterized in that: the main body (1) includes a frame (1005), mounted on the frame (1005) and arranged in a rectangular Four swivel casters (1003), and grain raising board I (1001) and grain raising board II (1002) installed on the frame (1005) and arranged longitudinally, the rear of the rack (1005) A push handle (1004) is also provided. 10. the using method of brush roller type safflower harvester according to claim 9, is characterized in that, comprises the following steps: When harvesting safflower filaments, drive the speed-regulating motor II to drive several brush rollers and feeding roller brushes II to rotate, and then drive the speed-regulating motor I to drive the cam (4001) and feeding roller brush I to rotate, and the cam (4001 ) when turning, push the profiling concave plate (4002) to move towards the brush roller, then push the push handle (1004) to drive the frame (1005) to move towards the safflower, so that the safflower moves from the feeding roller brush II to the feeding roller brush Ⅰ enters between the profiling concave plate (4002) and several brush rollers. At this time, the air is sent to the blowing pipe (5004), and the air flows along the holes to the profiling concave plate (4002). At this time, the brush rollers and The profiling concave plate (4002) collects the safflower filaments, and blows the safflower filaments into the collection box (5005) by ejecting air from the holes, thereby completing the harvesting of the safflower filaments.
