[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Example 1

[0026] Please see Figures 1 to 7In this embodiment of the present invention, an energy-saving crushing device includes a crushing box 14. Multiple support legs 1 are fixedly connected to the bottom side of the crushing box 14, and a feed nozzle 12 is fixedly connected to the top side of the crushing box 14. A first rotating rod 7 and a second rotating rod 13 are rotatably connected through the side wall of the crushing box 14. Crushing rollers 16 are fixedly connected to both the first rotating rod 7 and the second rotating rod 13. The two crushing rollers 16 are arranged opposite each other below the feed nozzle 12. A gear 15 is fixedly connected to one end of the second rotating rod 13 and the first rotating rod 7. The two gears 15 mesh with each other. A support plate 4 is fixedly connected to the side wall of the crushing box 14. A mounting platform 5 is fixedly connected to the upper side of the support plate 4. A motor 6 is fixedly installed on the upper side of the mounting platform 5. The output shaft of the motor 6 is fixedly connected to the end of the first rotating rod 7 that is away from the gear 15.

[0027] A water outlet pipe 9 is connected to the first rotating rod 7 via a liquid guiding device. The liquid guiding device includes a turntable 8, which is fixedly connected to the upper side of the support plate 4. The first rotating rod 7 is rotatably connected to the side wall of the turntable 8. A circular plate 19 is rotatably connected to the center of the turntable 8, and the circular plate 19 is fixedly connected to the first rotating rod 7. An annular cavity is formed between the inner circumferential side wall of the turntable 8 and the outer circumferential side wall of the circular plate 19. Two extrusion blocks 20 are fixedly connected to the outer side wall of the circular plate 19, and the two extrusion blocks 20 are located inside the annular cavity. A soft water pipe 3 is provided, with both ends of the soft water pipe 3 penetrating the side wall of the turntable 8. One end of the soft water pipe 3 is connected to the outlet pipe 9, and the other end of the soft water pipe 3 extends into the water tank 2, which stores water. After the first rotating rod 7 drives the circular plate 19 to rotate, the circular plate 19 can drive the two squeezing blocks 20 to rotate. The two squeezing blocks 20 can circulate and squeeze the soft water pipe 3 in the turntable 8, so that the soft water pipe 3 generates suction (similar to the principle of a peristaltic pump), and then the soft water pipe 3 inputs the water in the water tank 2 into the outlet pipe 9.

[0028] The water outlet pipe 9 is fixedly connected to the upper side of the crushing box 14 via the support rod 11. Multiple atomizing nozzles 10 are provided on the side wall of the water outlet pipe 9. All atomizing nozzles 10 face the top of the feed inlet 12. The bottom side of the crushing box 14 is fixedly connected to the discharge pipe 18. The bottom end of the discharge pipe 18 is threadedly connected to the sealing cap 17.

[0029] The working principle of this utility model is as follows:

[0030] In use, the motor 6 can be started first, which can drive the first rotating rod 7 to rotate. The rotation of the first rotating rod 7 then drives the second rotating rod 13 to rotate through the meshing of two gears 15. The first rotating rod 7 and the second rotating rod 13 rotate relative to each other. Then, the first rotating rod 7 and the second rotating rod 13 can drive the crushing rollers 16 on them to rotate relative to each other. After that, the material to be crushed can be put into the feed nozzle 12. Under the guidance of the feed nozzle 12, the material passes between the two crushing rollers 16, is crushed by the two crushing rollers 16, and falls to the bottom of the crushing box 14.

[0031] While the first rotating rod 7 is rotating, the first rotating rod 7 can drive the two extrusion blocks 20 to rotate through the circular plate 19. The two extrusion blocks 20 can circumferentially extrude the soft water pipe 3 in the turntable 8, so that the soft water pipe 3 generates suction. Then, the soft water pipe 3 inputs the water in the water tank 2 into the water outlet pipe 9. Finally, the water flow is sprayed out as water mist from multiple atomizing nozzles 10. The water mist is directed toward the top of the feed nozzle 12. The water mist can prevent the dust generated by the crushing roller 16 from spreading.

[0032] Example 2

[0033] The difference between Embodiment 2 and Embodiment 1 is that the surface of the crushing roller 16 is provided with a striped structure (not shown), which gives the surface of the crushing roller 16 stripes of a certain depth and spacing. This structure can increase the friction between the material and the crushing roller, making the material easier to grasp and crush during the crushing process.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
