[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] This utility model embodiment provides a biomass fuel pellet crushing mechanism, such as Figure 1-2 As shown, the crushing mechanism includes a crushing box 1, a crushing roller assembly 2 inside the crushing box 1, a feeding hopper 3 at the top of the crushing box 1, and a dust removal assembly 4. The dust removal assembly 4 includes a dust collection frame 41, which is a cuboid frame structure. The dust collection frame 41 is installed at the top opening of the feeding hopper 3, and a dust collection chamber 411 is provided inside the dust collection frame 41. The bottom of the dust collection frame 41 has a dust collection hole 412 that communicates with the dust collection chamber 411. The dust collection chamber 411 is connected to a vacuum cleaner 42 through a pipe. The crushing roller assembly 2 can crush the raw material, and at the same time, the dust generated during the crushing of the raw material can be sucked into the dust collection chamber 411 through the dust collection hole 412 at the bottom of the dust collection frame 41. Finally, the dust is sucked into the vacuum cleaner 42 for collection, so as to prevent the dust generated during the crushing of the raw material from drifting out of the crushing box 1 through the feeding hopper 3 and to prevent dust pollution from harming human health.

[0023] In this embodiment, the crushing roller assembly 2 includes two crushing rollers 21 disposed opposite to each other inside the crushing box 1. The two crushing rollers 21 are respectively connected to two gears 22. One of the gears 22 is connected to a drive device for driving the gear 22 to rotate. The drive device is one of an electric motor, a hydraulic motor, or a pneumatic motor.

[0024] Since the suction hole 412 at the bottom of the suction frame 41 is easily clogged during the vacuuming process, in order to facilitate the cleaning of the suction hole 412, in this embodiment, the top of the feed hopper 3 is provided with a first folded edge 31, and the bottom of the suction frame 41 is provided with a second folded edge 413. The first folded edge 31 and the second folded edge 413 are detachably connected on both sides by a connecting component 5. The first folded edge 31 and the second folded edge 413 can be detachably connected by the connecting component 5, so that the suction frame 41 can be detached from the top of the feed hopper 3 when the suction hole 412 at the bottom of the suction frame 41 is clogged, making it convenient to clean the suction hole 412.

[0025] For the connecting component 5, it only needs to satisfy the requirement of being able to detachably connect the first folded edge 31 and the second folded edge 413. Therefore, it is not limited to a specific structure. For example, in some embodiments, the connecting component 5 uses bolts.

[0026] In this embodiment, as Figure 3-5 As shown, the connecting assembly 5 includes a mounting sleeve 51 mounted on the second folded edge 413. A movable block 52 is provided inside the mounting sleeve 51. A connecting rod 53 is mounted at the central axis of the movable block 52. Both ends of the mounting sleeve 51 have through holes. One end of the connecting rod 53 passes through the through hole at one end of the mounting sleeve 51 and is fitted with a handle 54. The other end of the connecting rod 53 passes through the through hole at the other end of the mounting sleeve 51 and is fitted with a fixing rod 55. The movable block 52 and one end of the mounting sleeve 51 are connected by an elastic element 56, which is either a spring or an elastic metal sheet. The first folded edge 31 has a strip-shaped hole 311 that matches the fixing rod 55. When the dust collection frame 41 is installed on the top of the feed hopper 3, the dust collection frame 41 is placed on the top of the feed hopper 3, and the fixing rod 55 is inserted into the strip-shaped hole 311. Rotate the handle 54 to turn the fixing rod 55 out of the slot 311, thus misaligning the fixing rod 55 with the slot 311. Simultaneously, under the pushing force of the elastic element 56, the fixing rod 55 is pressed and fixed to the bottom of the second folded edge 413, thereby fixing the first folded edge 31 and the second folded edge 413 together. This allows the dust collection frame 41 to be installed on the top of the feed hopper 3. The fixing rod 55 is cylindrical, making it easy to turn out of the slot 311. When removing the dust collection frame 41 from the top of the feed hopper 3, rotate the handle 54 to align the fixing rod 55 with the slot 311. Under the pushing force of the elastic element 56, the fixing rod 55 enters the slot 311, thus loosening the first folded edge 31 and the second folded edge 413. This allows the dust collection frame 41 to be removed from the top of the feed hopper 3, making disassembly and assembly convenient.

[0027] To prevent the dust collection frame 41 from loosening after being installed on top of the feed hopper 3, a strip-shaped slot 312 matching the fixing rod 55 is installed at the bottom of the first folded edge 31 and at the strip-shaped hole 311. The strip-shaped slot 312 and the strip-shaped hole 311 are perpendicular to each other. When the dust collection frame 41 is installed on top of the feed hopper 3, the handle 54 is turned to rotate the fixing rod 5 into the slot 312. This prevents the fixing rod 55 from entering the strip-shaped hole 311 when the crushing mechanism is working, thus preventing the first folded edge 31 and the second folded edge 413 from loosening. This prevents the dust collection frame 41 from loosening after being installed on top of the feed hopper 3.

[0028] In this embodiment, the vacuum cleaner 42 includes a dust collection box 421, which is connected to the suction chamber 411 via a pipe and to a negative pressure pump 422 via a pipe. Figure 6 As shown, the dust collection box 421 includes a box body 4211, inside which is a drawer-type collection box 4212. The top of the box body 4211 has an air inlet 42111, which is connected to the dust suction chamber 411 through a pipe. The side of the box body 4211 has an exhaust port 42112, which is connected to the negative pressure pump 422 through a pipe. The drawer-type collection box 4212 and the exhaust port 42112 have a through hole 42121 opposite to the exhaust port 42112. The negative pressure pump 422 can suck dust into the box body 4211. The dust that enters the box body 4211 can fall into the drawer-type collection box 4212 for collection. At the same time, the drawer-type collection box 4212 can be pulled out from the box body 4211 for dust treatment. The exhaust port 42112 has a filter screen 42113 inside, which can prevent dust from entering the negative pressure pump 422.

[0029] The biomass fuel pellet crushing mechanism of this utility model can suck the dust generated during the crushing of raw materials into the dust suction chamber 411 through the dust suction hole 412 at the bottom of the dust suction frame 41, and finally suck it into the vacuum cleaner 42 for collection, so as to avoid the dust generated during the crushing of raw materials from drifting out of the crushing box 1 through the feed hopper and avoid dust pollution of the air and harm to human health.

[0030] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
