Trailed straw biomass granulator

A trailed straw biomass granulator, comprising a rack, a straw picking and processing device, a straw storage room, a straw conveying device, a trailing mechanism, a first drive device, and a forming device, wherein the straw picking and processing device, the straw storage room, the straw conveying device, the first drive device, and the forming device are all arranged on the rack;

• wherein the trailing mechanism is configured to drive the rack to move, the forming device comprises a driving gear and a forming gear;
• the first drive device is configured to drive the driving gear to rotate;
• wherein the driving gear is evenly distributed with the involute drive teeth in a circumferential direction, the storage groove is defined between two adjacent drive teeth, the driving gear comprises an output hole in an axial direction, and an auger is arranged inside the output hole;
• the forming hole is arranged between the two adjacent drive teeth on the driving gear, and the forming hole penetrates into the output hole and the storage groove;
• wherein the forming gear comprises a base body, a plurality of involute sliding teeth and a plurality of reset springs, the sliding teeth are evenly distributed on a peripheral side of the base body in the circumferential direction, and the sliding teeth are slidably arranged on the base body;
• the base body comprises a plurality of sliding grooves in one-to-one correspondence with the sliding teeth, the sliding teeth are integrally formed with a slide block, the slide block is slidably arranged inside the sliding grooves, the reset springs are disposed inside the sliding grooves, one end of the reset spring is fixedly connected inside the sliding grooves, and the other end is fixedly connected to the slide block;
• wherein the driving gear meshes with the forming gear, and the sliding teeth comprise at least a first working state and a second working state:
• wherein under the first working state, one side of the drive teeth contacts against one side of the sliding teeth, the reset springs extend, the sliding teeth deviate from the standard position, and the sliding teeth are configured to push the material into the storage groove, wherein the standard position is the position where the sliding teeth are not subjected to an external force;
• wherein under the second working state, the two sides of the sliding teeth respectively mesh with the two adjacent drive teeth, and the sliding teeth are configured to push the material inside the storage groove into the forming hole.
