[0025] 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 only used to explain this utility model and are not intended to limit this utility model.

[0026] To address the technical problem that existing crushing devices do not crush waste thoroughly enough, resulting in waste with a large volume after crushing, this invention provides a waste fine crushing device that can perform secondary crushing on incompletely crushed waste, ensuring that the crushed waste has a uniform particle size.

[0027] It should be noted that the waste crushing device described in this utility model is used for, but not limited to, crushing waste. For ease of explanation, this utility model will only use the application of a waste crushing device to crush waste as an example for illustration, and will not be described in detail here.

[0028] Please see Figures 1-4 , Figures 1-4According to one embodiment of the present invention, a waste crushing device includes a cylinder 1, a crushing mechanism 2, a conveying mechanism 3, and a lifting mechanism 4. The cylinder 1 has a cavity 1a, a feeding port 1b, and a discharging port 1c. The feeding port 1b and the discharging port 1c are located at the top and bottom of the cavity 1a, respectively, and are connected to the cavity 1a. The crushing mechanism 2 is installed on the cylinder 1 and has a crushing component 21. The crushing component 21 is located inside the cavity 1a and can crush the waste conveyed to the cavity 1a. The conveying mechanism 3 is installed on the cylinder 1 and passes through the cavity 1a. It can screen the crushed waste and convey the uncrushed waste out of the cavity 1a. The lifting mechanism 4 is installed on the cylinder 1 and is connected to the conveying mechanism 3. It can convey the uncrushed waste to the feeding port 1b.

[0029] In actual use, waste is conveyed to cavity 1a through feeding port 1b. Crusher 21 can crush the waste conveyed to cavity 1a. The crushed waste falls to conveying mechanism 3. Conveying mechanism 3 can screen out waste with smaller volume. Waste with smaller volume can be discharged out of cavity 1a through discharge port 1c. Waste that is not thoroughly crushed is conveyed to lifting mechanism 4. Lifting mechanism 4 can convey it back to feeding port 1b, where crusher 21 can crush it a second time.

[0030] Specifically, the inner diameter of the bottom of the cylinder 1 gradually decreases, and the waste that meets the crushing particle size and is screened by the conveying mechanism 3 can be discharged through the discharge port 1c at the bottom of the cylinder 1.

[0031] In one embodiment, the fine crushing mechanism 2 further includes two geared motors. The crushing components 21 are two crushing rollers that are spaced apart and rotatably disposed in the cavity 1a. A crushing gap is formed between the two crushing rollers. The two geared motors are fixed to the outside of the cylinder 1. The output ends of the two geared motors are respectively connected to the ends of the crushing rollers. Two baffles are respectively inclined on opposite sides inside the cylinder 1, and a feeding channel is formed between the two baffles. The width of the feeding channel gradually decreases towards the bottom of the cylinder 1, and the outlet of the feeding channel corresponds to the crushing gap.

[0032] It should be noted that, in one embodiment, the transmission mechanism 3 includes two side plates 31, a sleeve 32, an auger 33, and a driving component 34. The two side plates 31 are installed inside the cavity 1a, and a material guiding channel 31a is formed between the two side plates. The width of the material guiding channel gradually decreases towards the bottom of the cylinder 1. The sleeve 32 is installed on the cylinder 1 and passes through the cavity 1a. The side wall of the sleeve 32 has a discharge port 32a corresponding to the material guiding channel 31a, and the side wall of the sleeve 32 also has multiple screening holes 32b. The auger 33 is rotatably disposed inside the sleeve 32. The driving component 34 is fixed to one end of the sleeve 32 and connected to the auger 33. The driving component 34 is a geared motor.

[0033] Specifically, after the waste is crushed, it can fall into the guide channel 31a and be transported to the sleeve 32 through the outlet of the guide channel 31a. The drive unit 34 drives the auger 33 to rotate and can push the crushed waste to move. The waste with smaller particle size can pass through the screening hole 32b, while the waste that is not thoroughly crushed is transported to the lifting mechanism 4.

[0034] Based on the above scheme, both side plates 31 are provided with multiple material leakage holes 31b. The crushed material accumulates in the material guiding channel 31a, and smaller waste particles can pass through the material leakage holes 31b, effectively separating waste particles with qualified particle size from waste particles that are not thoroughly crushed.

[0035] It should be noted that, in one embodiment, the lifting mechanism 4 includes a lifting cylinder 41, a rotating shaft 42, a first helical blade 43, and a power component 44. The lifting cylinder 41 is fixedly connected to the cylinder body 1, and the lower end of the lifting cylinder 41 is connected to the sleeve 32. The rotating shaft 42 is coaxially and rotatably disposed inside the lifting cylinder 41. The first helical blade 43 is disposed inside the lifting cylinder 41 and connected to the rotating shaft 42. The power component 44 is installed on the lifting cylinder 41 and connected to the rotating shaft 42. The power component 44 is used to drive the rotating shaft 42 to rotate. The discharge pipe 411 at the upper end of the lifting cylinder 41 is connected to the feeding port 1b. The power component 44 is a drive motor.

[0036] Specifically, the bottom of the lifting cylinder 41 is connected to the sleeve 32. The power component 44 drives the rotating shaft 42 to rotate, thereby driving the first spiral blade 43 to rotate, which can lift the waste in the sleeve 32 to a preset height and transport the waste to the feeding port 1b again.

[0037] Based on the above scheme, the lifting mechanism 4 further includes a second spiral blade 45, which is disposed inside the lifting cylinder 41 and connected to the rotating shaft 42. The spiral direction of the second spiral blade 45 is opposite to that of the first spiral blade 43, and the connection between the second spiral blade 45 and the first spiral blade 43 corresponds to the unloading pipe 411.

[0038] It should be noted that when the waste is lifted to the connection between the first spiral blade 43 and the second spiral blade 45, the reverse rotation of the first spiral blade 43 and the second spiral blade 45 can squeeze the waste out of the discharge pipe 411.

[0039] Based on the above solution, to avoid generating more dust during waste crushing, a dust collection mechanism 5 is specifically included. The dust collection mechanism 5 includes a dust collection hood 51 and a dust removal component. The dust collection hood 51 is connected to the cylinder 1 and located above the feeding port 1b, and is connected to the dust removal component. It should be noted that the dust removal component is not limited to a specific structure. In one embodiment, the dust removal component includes an air pump and a bag filter, with the bag filter connected to the dust collection hood 51 via the air pump.

[0040] Based on the above scheme, in order to further crush the waste, a crushing mechanism 6 is specifically included. The crushing mechanism 6 includes multiple support rods 61, two telescopic members 62, and two pressure plates 63. The multiple support rods 61 are spaced apart in the cavity 1a and located above the crushing member 21. The axes of the multiple support rods 61 are located in the same horizontal plane, and a crushing zone is formed above the multiple support rods 61. The two telescopic members 62 are respectively installed on opposite sides of the cylinder 1, and the two pressure plates 63 are located in the crushing zone and are respectively connected to the output ends of the two telescopic members 62.

[0041] In one embodiment, both of the two pressure plates 63 are provided with crushing teeth on one side adjacent to each other, wherein both of the telescopic members 62 are electric cylinders. Of course, in other embodiments, the two telescopic members 62 can also be pneumatic cylinders or hydraulic cylinders.

[0042] 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.
