Biomass particle automatic detection and feeding device and control method thereof

The invention discloses an automatic biomass particle detecting and feeding device and a control method thereof. The automatic biomass particle detecting and feeding device comprises a storage bin and a feeding pipeline. One end of the feeding pipeline is inserted into the storage bin, and the other end of the feeding pipeline is inserted into the material box; an auger is arranged in one end of the feeding pipeline; the auger is connected with a feeding motor for driving the auger to rotate, the auger rotates to suck biomass particles through one end of the feeding pipeline, and then the biomass particles are discharged into the material box through the other end of the feeding pipeline; the device further comprises a material level detector. The material level detector is used for detecting the material level in the material box and connected with a main control board, and the main control board is connected with the feeding motor. And the main control board automatically controls a switch of the feeding mo
