Through searching, it can be seen that the wheat straw separation device for biomass pellets in the prior art has various functions. For example, a wheat straw separation device for biomass pellets with a Chinese patent authorization announcement number of CN209438973U drives the frame to reciprocate through an eccentric wheel, has a simple structure and is easy to use; the slider and the slide groove can guide the reciprocating vibration of the frame. Therefore, it can be seen that the existing wheat straw separation device for biomass pellets basically meets people's needs.
