[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 7This utility model provides an embodiment: a graded crushing sand making machine, including a first crushing chamber 1, a first optical shaft 23, and a crushing assembly. The crushing assembly is disposed at the bottom of the first crushing chamber 1. The first optical shaft 23 is rotatably connected inside the first crushing chamber 1. An eccentric roller 26 is fixedly connected to the inner side of the first optical shaft 23. A movable jaw plate 27 is rotatably connected inside the eccentric roller 26. A fixed jaw plate 28 is fixedly connected inside the first crushing chamber 1. A fixed bracket 29 is fixedly connected inside the first crushing chamber 1. A connecting plate 210 is rotatably connected inside the fixed bracket 29. The end of the connecting plate 210 away from the fixed bracket 29 rotates. Connected inside the movable jaw plate 27, a rotating sleeve 211 is rotatably connected to the end of the movable jaw plate 27 away from the eccentric roller 26. A sliding shaft 212 is slidably connected inside the rotating sleeve 211. A rotating block 213 is fixedly connected to the end of the sliding shaft 212 away from the rotating sleeve 211. The rotating block 213 is rotatably connected inside the fixed bracket 29. A spring 214 is fixedly connected between the sliding shaft 212 and the rotating sleeve 211. A hopper 215 is fixedly connected to the bottom of the first crushing chamber 1. A second crushing chamber 216 is fixedly connected to the bottom of the hopper 215. A first rotating shaft 218 is rotatably connected inside the second crushing chamber 216. A crushing roller 219 is fixedly connected to the outside of the first rotating shaft 218. A small gear 220 is fixedly connected to the outside of the first rotating shaft 218. A large gear 221 meshes with the outside of the small gear 220. A second rotating shaft 222 is fixedly connected inside the large gear 221. The crushing roller 219 is fixedly connected to the outside of the second rotating shaft 222. The crushing assembly starts the third motor 33, which drives the rotating rod 34 to rotate inside the third crushing chamber 32, which in turn drives the rotor 36 and the crushing hammer 37 to rotate. The stone is rapidly crushed by the crushing hammer 37 on the high-speed rotating rotor 36, and then crushed by the crushing hammer. The 37 causes the stone to be subjected to high-speed rotation in the third crushing chamber 32, causing it to be thrown out. The thrown stone undergoes multiple impacts, friction, and grinding with the wall strips 310 and crushing teeth 311, resulting in secondary crushing. Furthermore, the stones collide with each other, grinding away their sharp edges and making them round, thereby achieving the purpose of sand making. The rotating sleeve 211 has a matching groove at the corresponding position of the sliding shaft 212. The sliding shaft 212 slides in the groove of the rotating sleeve 211, which limits the sliding shaft 212, improves the sliding stability of the sliding shaft 212, and increases the reciprocating frequency of the movable jaw plate 27.

[0023] Please see Figure 1 - Figure 5In this embodiment, the first crushing chamber 1 has a corresponding groove at the corresponding position of the movable jaw plate 27. The movable jaw plate 27 moves within the groove of the first crushing chamber 1, so that the first crushing chamber 1 does not limit the movable jaw plate 27 during reciprocating motion, thereby improving the reciprocating efficiency of the movable jaw plate 27. Two crushing rollers 219 are provided, symmetrically distributed inside the second crushing chamber 216, and meshing with each other. Through the meshing of the small gear 220 and the large gear 221, the two crushing rollers 219 rotate in opposite directions, performing secondary crushing on the crushed stone. A first motor 21 is fixedly connected to the left end of the first crushing chamber 1. The output end of motor 21 is fixedly connected to a first rotating roller 22, and the outside of the first optical shaft 23 is fixedly connected to a second rotating roller 24. A conveyor belt 25 is connected between the second rotating roller 24 and the first rotating roller 22. The left end of the second crushing chamber 216 is fixedly connected to a second motor 217, and the first rotating shaft 218 is fixedly connected to the output end of the second motor 217. By pouring the stone between the fixed jaw plate 28 and the movable jaw plate 27, the stone is crushed in three stages to prevent loss during the user's transfer of the stone. The stone can be crushed into usable sand and gravel through the graded crushing chamber, so that the user does not need to transfer the stone and prevents unnecessary loss during the transfer process.

[0024] Please see Figure 6 - Figure 7In this embodiment, the crushing assembly includes a feeding frame 31, which is fixedly connected to the bottom of the second crushing chamber 216. A third crushing chamber 32 is fixedly connected to the bottom of the feeding frame 31. A third motor 33 is fixedly connected to the right end of the third crushing chamber 32. A rotating rod 34 is fixedly connected to the output end of the third motor 33. The rotating rod 34 is rotatably connected inside the third crushing chamber 32. A rotating disk 35 is fixedly connected to the outside of the rotating rod 34. A rotor 36 is fixedly connected to the outside of the rotating rod 34. A crushing hammer 37 is fixedly connected inside the rotor 36. A guide plate 38 is fixedly connected inside the third crushing chamber 32. A partition plate 39 is fixedly connected inside the third crushing chamber 32. A wall strip 310 is fixedly connected inside the third crushing chamber 32 and is fixedly connected inside the partition plate 39. Crushing teeth 311 are fixedly connected to the inner wall of the third crushing chamber 32. The crushing assembly drives the rotating rod 34 by starting the third motor 33. 4. The rotor 36 and the crushing hammer 37 rotate inside the third crushing chamber 32, causing them to rotate. The stone is initially crushed by the crushing hammer 37 on the high-speed rotating rotor 36. Then, the crushing hammer 37 causes the stone to be subjected to high-speed rotation in the third crushing chamber 32 and thrown out. The thrown stone is subjected to multiple impacts, friction and grinding between the wall strips 310 and the crushing teeth 311, resulting in secondary crushing. The stones collide with each other, grinding away their sharp edges and making them round, thus achieving the purpose of sand making. Several wall strips 310 are provided and distributed in sequence inside the partition 39, so that the stone is subjected to two or more impacts, friction and grinding in the third crushing chamber 32. The finely crushed stone becomes sand and gravel, which is discharged from the gaps between the wall strips 310 and blocked and diverted by the partition 39, thereby improving the fine crushing efficiency of the stone.

[0025] During operation, the user pours stone between the fixed jaw plate 28 and the movable jaw plate 27, and starts the first motor 21, which drives the first optical shaft 23 to rotate inside the first crushing chamber 1 via the conveyor belt 25. This drives the eccentric roller 26 to rotate, causing the movable jaw plate 27 to reciprocate via the connecting plate 210 and move within the rotating sleeve 211 via the sliding shaft 212. The spring 214 then rebounds, increasing the reciprocating frequency of the movable jaw plate 27, causing the stone to be crushed between the movable jaw plate 27 and the fixed jaw plate 28. The crushed stone falls through the hopper 215 between the two crushing rollers 219. At this point, the second motor 217 is started, and the small gear 220 and the large gear 221 mesh, causing the two crushing rollers 219 to rotate in opposite directions, performing secondary crushing on the crushed stone. The stone, after secondary crushing, enters the third crushing chamber 32 from the feed frame 31 and is guided by the guide plate 38. The flow is guided so that the stone material enters the third crushing chamber 32 in an orderly manner. By starting the third motor 33, it drives the rotating rod 34 to rotate inside the third crushing chamber 32, which in turn drives the rotor 36 and the crushing hammer 37 to rotate. The stone material is quickly crushed by the crushing hammer 37 on the high-speed rotating rotor 36. Then, the crushing hammer 37 makes the stone material rotate at high speed in the third crushing chamber 32 and throw it out. The thrown stone material is subjected to multiple impacts, friction and grinding between the wall strips 310 and the crushing teeth 311, which makes it undergo secondary crushing. Then, the stones collide with each other and grind away their edges and corners, making them rounded, thereby achieving the purpose of sand making. The stone material is subjected to two or more impacts, friction and grinding in the third crushing chamber 32. The sand and gravel produced by the fine crushing of the stone material is discharged from the gaps between several wall strips 310 and is blocked and diverted by the baffle 39, which improves the fine crushing efficiency of the stone material.

[0026] Through the above steps, by pouring the stone between the fixed jaw plate 28 and the movable jaw plate 27, the stone is crushed in three stages to prevent loss during the user's transfer of the stone for crushing. This allows the stone to be crushed into usable sand and gravel through the grading crushing chamber, eliminating the need for the user to transfer the stone and preventing unnecessary loss during the transfer process. This solves the problem of the stone needing to be transferred multiple times between different crushers, which increases the complexity of operation, is not only time-consuming, but also increases the uncertainty of the entire production process.
