[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The biomass particle screening device can directly pour the biomass particles into the inner wall of the screening frame through the coordinated use of the vibration motor and the filter plate, and then control the vibration motor to work through the controller, and use the power output shaft of the vibration motor to drive the filter plate to vibrate, so that the biomass particles dropped on the filter plate are vibrated and screened, so that when the smaller biomass particles pass through the filter plate and fall into the bottom of the screening frame, the larger biomass particles remain on the top of the filter plate, and then fall into the placement groove of the storage frame through the discharge port 1 opened at the bottom of the screening frame for collection, and then the storage frame can be pulled outward through the sliding connection of the T-block and the T-slot, so that the storage frame slides outward on the inner wall of the T-slot through the T-block, so that the storage frame can be taken out, which is convenient for collecting smaller biomass particles.

[0013] 2. The biomass particle screening device uses a baffle and a slide plate in coordination. By pulling the slide plate upward, the slide plate drives the baffle plate to slide upward on the inner wall of the retaining groove, so that the baffle plate squeezes the spring 2, causing the spring 2 to deform and shrink.

By setting the two springs 2 and utilizing the elastic potential energy of the spring 2 itself, when the discharge is completed, only the slide plate needs to be released, and the spring 2 can drive the baffle plate to slide downward on the inner wall of the retaining groove for automatic reset.
