Technical Field

[0001] The utility model relates to a biomaterial crushing device, belonging to the technical field of biomaterial processing. Background Art

[0002] Bio-based materials refer to a new type of material manufactured using renewable biomass through biological, chemical, physical and other means. The renewable biomass includes grains, straw, bamboo and wood powder, animal fur waste, etc. The prepared bio-based materials mainly include bioplastics, bio-based platform compounds, biomass functional polymer products, wood-based engineering materials, leather-based service materials, etc., which have excellent characteristics such as green environmental protection, renewable raw materials, and biodegradability.

[0003] Bio-based materials usually need to be crushed when they are discarded, recycled, tested, etc. During the crushing process of the bio-based materials, the crushing blades are always running and always collide and cut with the bio-based materials. The crushing blades will inevitably wear or break. The existing blades and stirring rods are usually a whole. When one of the blades has a problem, the entire blade group needs to be replaced, and the replacement cost is very high. Utility Model Content

[0024] like Figure 1-3 As shown, a biomaterial crushing device provided in this embodiment includes a crushing tank 1, a cover plate 2 is connected to the top of the crushing tank 1, and a driving motor 3 is arranged on the cover plate 2, wherein a discharge port is opened on the lower end surface of the crushing tank 1, and a second sealing plate 23 is threadedly connected to the discharge port, and the cover plate 2 is threadedly screwed and connected to the crushing tank 1, so as to facilitate the separation of the cover plate 2 from the crushing tank 1 in the later stage, and utilize the cover plate 2 to drive the removal of the driving motor 3 and the stirring rod 4 and a plurality of crushing blades 6 below, so as to replace the damaged or worn crushing blades 6; the driving motor 3 is fixedly connected to the cover plate 2, but the output shaft passes through the cover plate 2 and is not fixedly connected to the cover plate 2, and a protrusion 24 is arranged on the periphery of the cover plate 2, and a supporting leg is arranged on the lower end surface of the crushing tank 1, and the supporting leg lifts the crushing tank 1 to a certain height, so as to facilitate the later rotation of the second sealing plate 23 to discharge the biomaterial inside the crushing tank 1.

[0025] like Figure 1-3As shown, a stirring rod 4 is arranged inside the crushing tank 1, and the upper end of the stirring rod 4 passes through the cover plate 2 and is connected to the driving motor 3. A plurality of mounting blocks 5 are arranged on the surface of the stirring rod 4, and a crushing blade 6 is plugged into the mounting block 5. The crushing blade 6 includes a limit block 601 plugged into the mounting block 5 and a blade body 9 connected to the outer end of the limit block 601. An elastic pin for fixing the limit block 601 is arranged on one side of the mounting block 5.

[0026] Furthermore, if Figure 4-7 As shown, a limiting groove 602 for inserting the limiting block 601 is provided inside the mounting block 5, and the limiting groove 602 and the limiting block 601 are compatible square structures. The square structure has better stability than the cylindrical structure. A sliding groove 10 communicating with the limiting groove 602 is provided on one side of the mounting block 5 close to the elastic pin, and a slot 14 compatible with the sliding groove 10 is provided on the limiting block 601.

[0027] Furthermore, if Figure 4-7 As shown, the elastic latch includes a sliding cavity 11 arranged on one side of the mounting block 5 and communicating with the sliding groove 10, a limiting pin 12 slidably connected to the sliding groove 10 and the sliding cavity 11, and a compression spring 13 connected to one end of the limiting pin 12; a sealing plate 15 is arranged at the end of the sliding cavity 11 away from the mounting block 5, and a through hole with a diameter smaller than that of the compression spring 13 is opened on the surface of the sealing plate 15 to prevent the compression spring 13 from being separated from the sliding cavity 11, one end of the compression spring 13 is connected to the limiting block 601, and the other end of the compression spring 13 is connected to the sealing plate 15.
