[0022] 3. Drive one end of the horizontal storage box through the conveyor belt to contact the top of the limit slide 2 first. As the limit slide 2 moves to the other end of the storage box, it will push the horizontal storage box to rotate and tilt to pour the raw materials. After the storage box passes through the first limit slide 2, the storage box with the torsion spring will rotate and reset to contact the limit block to vibrate, thereby accelerating the unloading rate of the raw materials in the storage box. The dual effects of gravity and vibration can be effectively utilized to make the raw materials easier to pour out of the storage box, thereby increasing the unloading speed, preventing the material from accumulating and clogging in the storage box, and ensuring the smooth flow of raw materials.

A reciprocating conveying mechanism 300 is provided on one side of the inclined material distribution mechanism 200. The reciprocating conveying mechanism 300 is provided on one side of the crushing box 100. The reciprocating conveying mechanism 300 includes a rotating roller 301 rotatably connected to the inner wall of the crushing box 100. A limiting roller 302 is fixedly connected to the inner wall of the crushing box 100. A conveyor belt 303 is sleeved on the rotating roller 301. The limiting roller 302 limits the sleeved conveyor belt 303 so that the conveyor belt 303 presents an overturned L-shape. The top of the conveyor belt 303 is in an inclined state. Storage assemblies are installed at intervals on the conveyor belt 303. The screened bulk raw materials are re-conveyed to the crushing roller 1 202 and the crushing roller 2 205 through the storage assembly to perform secondary crushing on the bulk raw materials.

[0038] Specifically, the initial raw materials are poured into the crushing box 100 from the feed port 201 for crushing, and the driving gear 203 and the driven gear 204 meshing with each other on the inner wall of the crushing box 100 are driven by the motor to rotate, so that the crushing roller 1 202 and the crushing roller 205 rotate in the crushing box 100 to crush the falling raw materials. The crushed raw materials will fall onto the flip plate 206 below for screening, and the flip plate 206 is pushed by the swing component to shake on the material separation component. The screening speed of the raw materials on the flip plate 206 is accelerated, and the large pieces of raw materials screened are transported to the storage component on one side through the flip plate 206.

[0039] The swing assembly drives the flip plate 206 to swing to speed up the screening of raw materials, and the flip plate 206 intercepts the large pieces of raw materials that fall after being crushed. The large pieces of raw materials intercepted on the flip plate 206 are poured into a storage assembly on one side, and the storage assembly filled with raw materials is driven by the conveyor belt 303 to return to the top of the crushing roller 1 202 and the crushing roller 2 205, so that the raw materials are crushed for the second time. Larger particles that do not meet the particle size requirements after the initial crushing can be further crushed, so that the particle size of the final product is more uniform and consistent. The uniform particle size is conducive to the uniform mixing of the components in the subsequent processing process, thereby ensuring the stability of product quality.

[0042] One end of the sliding rack 211 is fixedly connected to a driving bevel block 212, and a flip gear 213 is meshed above the sliding rack 211. A mounting tube 214 is sleeved on one side of the flip gear 213. One end of the mounting tube 214 is fixedly connected to the inner wall of the mounting plate 208, and the flip gear 213 is rotatably connected to the mounting tube 214.

[0043] A mounting through hole 215 is provided on the mounting plate 208, and the mounting through hole 215 extends to one end of the mounting tube 214. Both sides of the flip plate 206 are fixedly connected with a limiting sliding shaft 216. The limiting sliding shaft 216 is slidably connected to the flip gear 213. The flip gear 213 has a through hole that can be matched with the limiting sliding shaft 216. The limiting sliding shaft 216 will move into the mounting through hole 215 through the mounting tube 214 during the swinging process.

[0044] A limit installation groove is provided on the flip plate 206, and a filter plate 217 is fitted in the limit installation groove. One end of the limit installation groove is an acute angle shape in the flip plate 206, and the other end is a vertical plane. The acute angle shape at one end can intercept smaller raw materials when the materials are tilted for distribution, while larger raw materials can pass smoothly.

[0045] The swing assembly includes a limiting slide column 218 fixedly connected between the mounting plates 208 on both sides, a limiting slide plate 219 slidably connected to the limiting slide column 218, a hinge block 220 fixedly connected to the lower surface of the flip plate 206, the hinge blocks 220 are respectively arranged at both ends of the flip plate 206, a hinge block 221 is rotatably connected to the hinge block 1 220, the lower surface of the hinge block 221 is in contact with the upper surface of the limiting slide plate 219, a lifting slider 222 is fixedly connected to the lower surface of the hinge block 221, the lifting slider 222 is slidably connected to the limiting slide plate 219, and a rotating shaft is fixedly connected to one side of the limiting slide plate 219.

[0046] A transmission rod 223 is rotatably connected to one side of the limiting slide plate 219, one end of the transmission rod 223 is sleeved with the rotating shaft, one end of the transmission rod 223 is rotatably connected to a rotating disc 224, a motor 225 is fixedly installed on one side of the rotating disc 224, a mounting frame 226 is fixedly installed on the motor 225, and the mounting frame 226 is fixedly connected to the inner wall of the crushing box 100.

[0047] Specifically, initially, the flip plate 206 is in a horizontal state, and the hinge block 221 at one end of the flip plate 206 is placed on the upper surface of the limiting slide plate 219. The crushed raw materials are screened by the filter plate 217 installed on the flip plate 206, and the rotating disc 224 is driven to rotate by the output end of the motor 225. At the same time, the limiting slide plate 219 at one end is driven by the transmission rod 223 to slide back and forth on the limiting slide column 218, so that the limiting slide shafts 216 on both sides of the flip plate 206 slide along the installation through holes 215. When the storage assembly on the conveyor belt 303 is driven to move by the rotating roller 301, it will intermittently conflict with the driving inclined block 212. When the driving inclined block 212 conflicts with the storage assembly, the sliding block 212 on one side of the sliding rack 211 0 will slide along the limiting slide 209 on the mounting plate 208, and while the sliding rack 211 slides, it drives the meshing flip gear 213 to rotate on the mounting cylinder 214, and the rotation of the flip gear 213 drives the matching limiting sliding shaft 216 to make the flip plate 206 rotate and tilt. During the rotation and tilting process of the flip plate 206, the lifting slide block 222 below is pulled by the hinge block 1 220 to slide upward along the limiting slide plate 219. As the flip plate 206 tilts, the hinge block 1 220 will rotate along the hinge block 221, and the raw materials on the filter plate 217 will be collected into the acute-angle groove on one side. As the flip plate 206 tilts, the smaller raw materials will slide and fall into the acute-angle groove, and the larger raw materials will roll through the acute-angle groove and fall into the storage component on one side.

[0048] Example 3

[0049] Reference Figure 7-Figure 9, which is the third embodiment of the present invention, provides a crushing device, the storage component includes a mounting block 304 fixedly connected to the surface of the conveyor belt 303, both ends of the mounting block 304 are fixedly connected to the limiting inclined blocks 305, the torsion spring on the mounting block 304 is connected to a rotating plate 306, one end of the rotating plate 306 is fixedly connected to a storage box 307, the conveyor belt 303 will drive the storage boxes 307 arranged at intervals to pass through the gap between the conveyor belt 303 and the flip plate 206, so that the storage box 307 filled with raw materials moves from the bottom end of the conveyor belt to the top end.

[0050] One side of the limiting inclined block 305 is fixedly connected to the limiting block 308, and the limiting blocks 308 are fixedly connected to the two ends of the mounting block 304 respectively. The surface of the limiting block 308 conflicts with the side of the storage box 307. The inner walls on both sides of the crushing box body 100 are fixedly connected with a fixing frame 309, and a limiting slide column 2 310 is fixedly installed on the fixing frame 309. The limiting slide column 2 310 intermittently conflicts with the side of the storage box 307.

[0051] Specifically, the rotating roller 301 on the inner wall of the crushing box 100 drives the sleeved conveyor belt 303 to rotate, so that the rotation of the conveyor belt 303 drives the limiting bevel blocks 305 at both ends of the mounting block 304 to slide and conflict with the driving bevel block 212 on one side. As the limiting bevel block 305 rises, it will gradually push the driving bevel block 212 on one side to slide, and the rotating plate 306 of the torsion spring will drive the storage box 307 to pass through the gap between the reciprocating conveying mechanism 300 and the inclined material distribution mechanism 200. The inclined flip plate 206 pours the raw materials from the filter plate 217 into the storage box 307 in the gap. When the limiting bevel block 305 passes over the driving bevel block 212, the flip plate 206, under the action of gravity, meshes with each other. The flip gear 213 and the sliding rack 211 push the driving bevel block 212 to slide and reset. When the reciprocating conveying mechanism 300 drives the storage box 307 filled with raw materials to move to the top, the two ends of the storage box 307 will intermittently contact the limiting slide column 2 310 on both sides. One end of the horizontal storage box 307 will first contact the top of the limiting slide column 2 310, and as the limiting slide column 2 310 moves to the other end of the storage box 307, during this process, the horizontal storage box 307 will be pushed to rotate and tilt to pour the raw materials. After the storage box 307 passes through the first limiting slide column 2 310, the storage box 307 with the torsion spring will rotate and reset to contact the limiting block 308 to vibrate, thereby accelerating the unloading rate of the raw materials in the storage box 307.

The crushed raw materials will fall on the flip plate 206 below for screening, and the flip plate 206 is pushed by the swing component to shake on the material separation component to increase The screening speed of the raw materials on the quick flip plate 206 is fast, and the large pieces of raw materials screened are transported to the storage component on one side through the flip plate 206. The rotation of the rotating roller 301 drives the sleeved conveyor belt 303 to transport the large pieces of raw materials to the top of the crushing roller 1 202 and the crushing roller 2 205 again. The conveyor belt 303 is limited by the limiting roller 302, so that the top of the conveyor belt 303 is in an inclined state. After the storage component moves to the top, it will tilt, and the large pieces of raw materials will be scattered for secondary crushing.
