[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-6 As shown, this invention illustrates a multi-stage crushing device for blocky powder in one embodiment, comprising: a housing 1, a feeding component 2 installed at the top of the housing 1, a spraying component 3 installed at the top of the housing 1 and to the right of the feeding component 2; a driving component 4, a driving component 4 installed at the right end of the housing 1, a crushing component 5 installed inside the housing 1, a connecting component 6 installed at the right end of the crushing component 5, a grinding component 7 installed inside the housing 1 and below the crushing component 5, a storage box 8 provided inside the housing 1 and near the bottom, an isolation net 9 fixedly connected inside the storage box 8, and a drain pipe 10 fixedly connected at the right end of the storage box 8 and near the bottom.

[0031] For example, such as Figure 3 As shown, the drive assembly 4 includes a support plate 41. The support plate 41 is fixedly connected to the right end of the housing 1. The drive motor 42 is fixedly connected to the top of the support plate 41. A rotating rod 43 is fixedly installed at the output end of the drive motor 42. A drive wheel 44 is fixedly connected to the rotating rod 43. A driven rod 46 is rotatably connected to the rear end of the housing 1. A flywheel 47 is fixedly connected to the driven rod 46. A counterweight 48 is fixedly connected to the flywheel 47. A transmission belt 45 drives the flywheel 47 and the drive wheel 44. When the drive motor 42 is started, it drives the drive wheel 44 to rotate through the rotating rod 43. The drive wheel 44 causes the flywheel 47 to rotate through the transmission belt 45. Different transmission ratios can be achieved by reasonably designing the size of the drive wheel 44 and the flywheel 47, which is convenient for cooperating with the crushing assembly 5 to crush raw materials.

[0032] For example, such as Figure 2 As shown, the crushing assembly 5 includes a fixed plate 51, which is fixedly connected to the top wall of the inner cavity of the housing 1. A fixed jaw plate 52 is fixedly connected to the right end of the fixed plate 51. The front end of the driven rod 46 extends into the interior of the housing 1 and is fixedly connected to an eccentric shaft 55. A support frame 53 is fixedly connected to the eccentric shaft 55. A movable jaw plate 54 is fixedly connected to the left end of the support frame 53. The flywheel 47 causes the eccentric shaft 55 to rotate through the driven rod 46. The eccentric shaft 55 drives the movable jaw plate 54 to perform periodic reciprocating motion due to the eccentricity generated when it rotates, which causes the volume of the crushing chamber to change, thereby cooperating with the fixed jaw plate 52 to apply crushing forces such as squeezing and splitting to the material.

[0033] For example, such as Figure 2 As shown, the connecting component 6 includes a fixing block 63. The right end of the support frame 53 is fixedly connected to the fixing block 63. The inside of the fixing block 63 is rotatably connected to the slide rod 64 through a ball joint. The inside of the box 1 is fixedly connected to the positioning plate 65. The right end of the slide rod 64 extends to the right side of the positioning plate 65. The right end of the positioning plate 65 is fixedly connected to the spring 66. The right end of the support frame 53 and located above the fixing block 63 is fixedly connected to the fixing member 61. The inside of the fixing member 61 is fixedly installed with an elbow plate 62. The right end of the elbow plate 62 is connected to the inside of the box 1. The movable jaw plate 54 drives the support frame 53 to make the slide rod 64 slide inside the positioning plate 65. During the swing of the movable jaw, the elastic force of the spring pulls the movable jaw to prevent it from shaking violently due to inertia, ensuring a smooth crushing process.

[0034] For example, such as Figure 2 As shown, the grinding assembly 7 includes a main spindle motor 71. The main spindle motor 71 is fixedly connected to the rear end of the housing 1. The output end of the main spindle motor 71 extends into the interior of the housing 1 and is fixedly mounted on a drive shaft 72. A drive grinding roller 74 is fixedly connected to the drive shaft 72. A driven shaft 73 is rotatably connected to the left end of the drive grinding roller 74 inside the housing 1 via a bearing. A driven grinding roller 75 is fixedly connected to the driven shaft 73. The front end of the driven shaft 73 extends to the front side of the housing 1 and is fixedly connected to a drive gear 76. The front end of the drive shaft 72 extends to the front side of the housing 1 and is fixedly connected to a driven gear 77. The drive gear 76 and the driven gear 77 mesh with each other. When the main spindle motor 71 is started, it drives the drive shaft 72 to rotate. Then, through the meshing between the drive gear 76 and the driven gear 77, the driven shaft 73 rotates, causing the drive grinding roller 74 and the driven grinding roller 75 to grind together. Multiple grinding processes result in higher pulverization efficiency.

[0035] In some examples, after the raw material is added through the feeding assembly 2, the drive assembly 4 starts working, and the drive motor 42 drives the drive wheel 44 to rotate through the rotating rod 43. The drive wheel 44 drives the flywheel 47 to rotate through the transmission belt 45. Different transmission ratios can be achieved by reasonably designing the size of the drive wheel 44 and the flywheel 47, which is convenient for cooperating with the crushing assembly 5 to crush the raw material. When the crushing assembly 5 is working, the flywheel 47 drives the eccentric shaft 55 to rotate through the driven rod 46. The eccentric shaft 55 drives the movable jaw plate 54 to perform periodic reciprocating motion due to the eccentricity generated when rotating, so that the volume of the crushing chamber changes. This, in conjunction with the fixed jaw plate 52, applies crushing forces such as squeezing and splitting to the material. At the same time, the connecting assembly 6 works, and the movable jaw plate 5... 4. The support frame 53 drives the slide bar 64 to slide inside the positioning plate 65. During the swing of the moving jaw, the elastic force of the spring pulls the moving jaw to prevent it from shaking violently due to inertia, ensuring a smooth crushing process. At the same time, the toggle plate 62, as the connecting part between the moving jaw and the box 1, transmits the movement of the eccentric shaft 55 to the moving jaw, causing the moving jaw to swing back and forth, thereby squeezing and crushing the material. After coarse crushing, the grinding assembly 7 starts, and the main shaft motor 71 drives the drive shaft 72 to rotate. Then, through the meshing between the drive gear 76 and the driven gear 77, the driven shaft 73 rotates, so that the drive grinding roller 74 and the driven grinding roller 75 cooperate to grind. Multiple grinding makes the crushing efficiency higher and saves the time of conveying materials.

[0036] like Figures 1-5 As shown, this invention illustrates a multi-stage crushing device for lumpy powder in another embodiment. The feeding assembly 2 includes a housing 21. The housing 21 is fixedly connected to the top of the box 1. A servo motor 22 is fixedly connected to the right end of the housing 21. The output end of the servo motor 22 extends into the interior of the housing 21 and is fixedly mounted with a rotating shaft 23. A propeller blade 24 is fixedly connected to the rotating shaft 23. A feeding hopper 25 is installed at the top of the housing 21. When the servo motor 22 is started, it drives the rotating shaft 23 to make the propeller blade 24 work, continuously feeding material into the interior of the box 1, which facilitates control of the feeding amount of lumpy powder.

[0037] For example, such as Figure 5 As shown, the spraying assembly 3 includes a water storage tank 31. The water storage tank 31 is fixedly connected to the top of the tank body 1 and located on the right side of the feeding assembly 2. A water pump 32 is fixedly connected to the top of the water storage tank 31. A water inlet pipe 33 is fixedly installed at the water inlet end of the water pump 32. The end of the water inlet pipe 33 extends into the interior of the water storage tank 31. A water outlet pipe 34 is fixedly installed at the water outlet end of the water pump 32. The end of the water outlet pipe 34 extends into the interior of the tank body 1 and is fixedly connected to a nozzle 35. When the water pump 32 is started, the cooling water in the water storage tank 31 is sprayed out through the water inlet pipe 33 and the water outlet pipe 34 and then sprayed out by the nozzle 35 to cool down the heat generated during crushing.

[0038] In some examples, the pre-crushing feeding component 2 is activated, and the servo motor 22 drives the rotating shaft 23 to make the propeller blade 24 work, continuously feeding material into the box 1. The servo motor 22 is equipped with a high-precision encoder, which can accurately feed back the rotor position, realize precise position control and speed control, and facilitate control of the feeding amount of block powder. At the same time, during crushing, the spraying component 3 is activated, and the water pump 32 is activated to spray the cooling water in the water storage tank 31 through the water inlet pipe 33 and the water outlet pipe 34 and the nozzle 35 to cool down the heat generated during crushing and maintain the normal working environment of crushing.
