[0002] Biomass pellet fuel is essentially the direct combustion application of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology.

[0003] After searching, a utility model with Chinese patent publication number CN219789398U discloses a biomass fuel extrusion device, including a mounting seat, a servo motor is fixedly mounted on the top of the mounting seat, a lead screw is fixedly connected to the output end of the servo motor, a threaded sleeve is threadedly connected to the outer side of the lead screw, six push rods are fixedly connected to the right end of the threaded sleeve, the other ends of the six push rods are fixedly connected to the extrusion plate, and an extrusion box is arranged on the outer side of the extrusion plate.

[0004] When the above-mentioned device is pressing the raw materials, since the feed port at the top of the extrusion box is connected to the outside, if the raw materials are filled too much, as the pressing proceeds, some of the raw materials will inevitably return to the feed port range due to the increase in pressure and cannot be used. In addition, since the volume of the extrusion box is large, it needs to be leveled again after filling once, which is time-consuming. Utility Model Content

A baffle plate 1 is provided on one side of the inner wall at both ends of the extrusion box, and the baffle plate 1 can block the lower end opening of the feed port.

The motor shaft drives the reciprocating screw to rotate on one side of the vertical plate. Because the feed port is restricted by the extrusion box, and the connecting frame is connected to the extrusion box, the reciprocating screw can drive the feed port and baffle 2 to reciprocate on the top of the extrusion box, and the raw materials falling from the bottom of the feed port will gradually fill the extrusion box. Finally, the feed port returns to its original position, baffle 1 can block the bottom of the feed port, and baffle 2 can cover the opening at the top of the extrusion box.

[0015] (1) The utility model provides a feeding assembly and a baffle so that the feed port can slide back and forth on the top of the extrusion box, thereby ensuring that the material is evenly spread in the extrusion box, thereby eliminating the need for subsequent sorting. When the feed port stops, its bottom is closed to prevent the raw materials from returning to the feed port again. The motor shaft drives the reciprocating screw to rotate on one side of the vertical plate. Because the feed port is restricted by the extrusion box and the connecting frame is connected to the extrusion box, the reciprocating screw can drive the feed port and baffle 2 to move back and forth on the top of the extrusion box. The raw materials falling from the bottom of the feed port will gradually fill the extrusion box. Finally, the feed port returns to its original position, and baffle 1 can block the bottom of the feed port, while baffle 2 can cover the opening at the top of the extrusion box.

[0016] (2) The utility model provides a molding assembly. If it is necessary to process other types of fuel particles, the utility model only needs to drive a pulley to rotate through the handle. This pulley can drive several other pulleys to rotate simultaneously through the belt, and then the bolts connected to the molding frame will be driven by the pulley to gradually detach from the connection with the extrusion box. Then, the molding frame is pulled to slide in the limit groove until one of the molding plates is aligned with the outlet of the extrusion box, and then the corresponding multiple bolts are driven to re-enter the extrusion box to complete the replacement work.

Because the feed port 601 is restricted by the extrusion box 2, and the connecting frame 603 is connected to the extrusion box 2, the reciprocating screw 604 can drive the feed port 601 and the baffle 2 602 to reciprocate on the top of the extrusion box 2, and the raw materials falling from the bottom of the feed port 601 will gradually fill the extrusion box 2.

Finally, the feed port 601 returns to its original position, the baffle 1 8 can block the bottom of the feed port 601, and the baffle 2 602 can cover the opening at the top of the extrusion box 2, and then the hydraulic cylinder 4 is started, and its output end drives the end The extrusion plate moves toward the inside of the extrusion box 2, and the extrusion plate can gradually compress the raw material, and then it comes out from the multiple holes of the forming frame 702.
