DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0021] Example 1: A biomass pelletizer with a cleaning mechanism, such as Figure 1-Figure 7 As shown, it includes a base frame 1, a serving plate 2, an extruder 3, a forming die 4, a guide ring 5, a sliding plate 6, a roller brush 7, a scraper 8, a common spring 9, a first gear 10, a first gear ring 11, an extrusion cylinder 12, a drive assembly and a pushing assembly. The upper side of the base frame 1 is fixedly connected to the serving plate 2, and a feeding port is opened on the front side of the serving plate 2. The serving plate 2 is fixedly connected to the extruder 3, and the lower part of the extruder 3 is fixedly connected to the forming die 4. The extruder 3 is rotatably connected to the guide ring 5, and the lower side of the guide ring 5 is slidably connected to four sliding plates 6 distributed equidistantly around the circumference. The sliding plate 6 is rotatably connected to the receiving plate 2. There is a roller brush 7, a scraper 8 is fixedly connected to the sliding plate 6, an ordinary spring 9 is connected between the sliding plate 6 and the guide ring 5, a first gear 10 is fixedly connected to the upper part of the roller brush 7, a first gear ring 11 is fixedly connected to the upper part of the forming die 4, an extrusion cylinder 12 is slidably connected to the guide ring 5, and the extrusion cylinder 12 is a conical structure that is narrow at the top and wide at the bottom. The extrusion cylinder 12 moves downward to be extruded and matched with the sliding plate 6. A driving component for driving the roller brush 7 and the scraper 8 to clean the surface of the forming die 4 is provided on the guide ring 5 and the extruder 3, and a pushing component for pushing out the biomass particles is provided on the holding plate 2.

[0022] In the initial state, the roller brush 7 and the scraper 8 are not in contact with the surface of the forming die 4, and the first gear 10 and the first gear ring 11 are not engaged. When using the device, the staff introduces the debris raw material into the extruder 3, and the extruder 3 extrude the raw material through the forming die 4 for granulation. The naturally broken biomass particles fall on the receiving plate 2, and the biomass particles are gathered and pushed out by the pushing assembly for unloading. During the granulation process, the staff drives the guide ring 5 to rotate through the driving assembly, and the rotation of the guide ring 5 drives the scraper 8 to rotate through the sliding plate 6. At this time, the scraper 8 is not in direct contact with the surface of the forming die 4, so the scraper 8 can cut off the biomass particles extruded by the forming die 4 when it rotates, so as to prevent the extruded biomass particles from extending out of the receiving plate 2 and falling to the ground. When the use of this device is completed, the staff pushes the extrusion cylinder 12 to slide downward, and the extrusion cylinder 12 slides downward to extrude the sliding The plate 6 slides backward, the ordinary spring 9 is deformed, and the sliding plate 6 slides inward, driving the roller brush 7, the scraper 8 and the first gear 10 to move inward. The roller brush 7 and the scraper 8 move inward and contact the surface of the forming mold 4. After the first gear 10 moves inward, it meshes with the first ring gear 11. At this time, the first gear 10 revolves while meshing with the first ring gear 11 and rotates, thereby driving the roller brush 7 to rotate. The scraper 8 and the roller brush 7 clean the surface of the forming mold 4 one after the other. When the cleaning is completed, the staff releases the extrusion cylinder 12. Under the action of the ordinary spring 9 resetting, the sliding plate 6 drives the roller brush 7, the scraper 8 and the first gear 10 to move outward and reset. The outward movement of the sliding plate 6 will also push the extrusion cylinder 12 to slide upward and reset. In this way, the material residue and dust accumulation on the surface of the forming mold 4 can be cleaned, which helps to ensure the normal operation of the equipment and extend its service life.

[0023] Example 2: Based on Example 1, Figure 1 and Figure 2 As shown, the driving assembly includes a second ring gear 121, a driving motor 122 and a second gear 123. The second ring gear 121 is fixedly connected to the upper part of the guide ring 5, and the driving motor 122 is fixedly connected to the left side of the extruder 3. The second gear 123 is fixedly connected to the output shaft of the driving motor 122, and the second gear 123 is engaged with the second ring gear 121.

[0024] When the device is used, the driving motor 122 drives the second gear 123 to rotate, the rotation of the second gear 123 drives the second ring gear 121 to rotate, the rotation of the second ring gear 121 drives the guide ring 5 to rotate, and then drives the roller brush 7 and the scraper 8 to rotate to clean the surface of the forming mold 4.

[0025] like Figure 1 、 Figure 6 and Figure 7As shown, the pushing assembly includes a mounting block 13, a pushing plate 14, a spiral spring 15, a blocking frame 16, a blocking block 17 and a discharging frame 18. The scraper 8 is fixedly connected to the mounting block 13 at the lower part, and the pushing plate 14 is rotatably connected to the mounting block 13. The pushing plate 14 is tilted and is used to push the biomass particles inside outward. A spiral spring 15 is connected between the pushing plate 14 and the adjacent mounting block 13. The blocking frame 16 is fixedly connected to the containing tray 2, and the inner front side of the blocking frame 16 is fixedly connected to the blocking block 17. The pushing plate 14 rotates clockwise to squeeze and fit with the blocking block 17. The front lower side of the containing tray 2 is fixedly connected to the discharging frame 18 connected to the discharge port.

[0026] When the device is used, the cut biomass particles fall onto the receiving plate 2 and are blocked by the blocking frame 16 to prevent them from falling to the ground. When the scraper 8 revolves, it will drive the pushing plate 14 to rotate together through the mounting block 13. The rotation of the pushing plate 14 can push the biomass particles toward the discharge port. When the pushing plate 14 rotates clockwise until it contacts the stopper 17, the pushing plate 14 will be squeezed by the stopper 17, and the inner end of the pushing plate 14 will swing outward. The volute spring 15 will deform, and the outward swing of the inner end of the pushing plate 14 will push the biomass particles on the inside toward the discharge port, so that the biomass particles can better enter the discharge port. When the pushing plate 14 rotates to disengage from the stopper 17, the volute spring 15 will reset the pushing plate 14, and the biomass particles falling out of the discharge port will be guided to the outside through the discharge frame 18 for external transportation.

[0027] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
