[0026] Referring to Figure 4 , guide grooves 209 are respectively formed in the front side and the back side of the inner cavity of the support frame 204, the inner cavity of the guide groove 209 is movably connected with the surface of the guide plate 211, a movable groove 213 is formed in the top of the inner cavity of the guide groove 209, and the inner cavity of the movable groove 213 is movably connected with the surface of the traction wire 202. Through the arrangement of the guide groove 209, it plays a guiding role in the movement of the guide plate 211, preventing the position of the guide plate 211 from shifting during the movement process. Through the arrangement of the movable groove 213, the traction wire 202 can pass through the inside of the support frame 204 to drive the guide plate 211 to move, thereby making the movement of the guide plate 211 more stable.

[0027] Referring to Figure 4 , a support shaft 208 is fixedly connected to the inner cavity of the support frame 204, a fixed seat 205 is fixedly connected to the surface of the support shaft 208, and the left side of the fixed seat 205 is fixedly connected to the left side of the inner cavity of the machine body 101. Through the arrangement of the fixed seat 205, the position of the support shaft 208 is fixed, and thus through the arrangement of the support shaft 208, it plays a supporting role in the position of the support frame 204, preventing the position of the support frame 204 from shifting during use.

[0028] Referring to Figure 2 and Figure 3, a screening mechanism 3 is installed in the inner cavity of the body 101. The screening mechanism 3 includes a first screening plate 308, a second screening plate 304, and a third screening plate 306. The surfaces of the first screening plate 308, the second screening plate 304, and the third screening plate 306 are fixedly connected to the inner cavity of the body 101.

Through the arrangement of the first screening plate 308, the second screening plate 304, and the third screening plate 306, the raw materials entering the inside of the body 101 are screened multiple times. At the same time, through the arrangement of the first drainage plate 307 and the second drainage plate 305, the raw material particles that have met the requirements are drained and guided, reducing the amount of raw materials entering the inside of the first crushing roller 110 and the second crushing roller 112, thereby improving the crushing efficiency of the first crushing roller 110 and the second crushing roller 112.

Through the arrangement of the first baffle 301, the movement of the raw materials entering the inside of the body 101 is blocked, preventing the raw materials from directly entering the inside of the first crushing roller 110 without being screened by the first screening plate 308, thereby increasing the processing capacity of the first crushing roller 110. Through the arrangement of the second baffle 303, the movement of the raw materials after primary screening is blocked, preventing the rolling speed of the raw materials from being too fast and failing to enter the inside of the first crushing roller 110 for crushing.

[0030] Refer to Figure 2 , a filter plate 302 is fixedly connected to the bottom of the body 101. The surface of the filter plate 302 is fixedly connected to the inner cavity of the discharge port 103. Through the arrangement of the filter plate 302, the raw materials that have met the requirements are filtered, removing impurities and dust therein, thereby improving the purity and cleanliness of the product.

[0031] Refer to Figure 1 and Figure 5, a support plate 104 is fixedly connected to the front side of the body 101. A first motor 105 is fixedly connected to the top of the support plate 104. The output end of the first motor 105 is fixedly connected to a first gear 111. Both sides of the surface of the first gear 111 are meshed and connected with second gears 107. A positioning shaft 106 is movably connected to the inner cavity of the second gear 107. The back side of the positioning shaft 106 is fixedly connected to the front side of the body 101. Both sides of the top surface of the second gear 107 are meshed and connected with third gears 109. A first connecting shaft 108 is fixedly connected to the inner cavity of the third gear 109. A first crushing roller 110 is fixedly connected to the surface of the first connecting shaft 108. Both sides of the bottom surface of the second gear 107 are meshed and connected with fourth gears 113. A second connecting shaft 114 is fixedly connected to the inner cavity of the fourth gear 113. A second crushing roller 112 is fixedly connected to the surface of the second connecting shaft 114. Through the setting of the first motor 105, the first gear 111 will be driven to rotate during its rotation process. The rotation of the first gear 111 drives the second gear 107 to rotate. The rotation of the second gear 107 drives the third gear 109 and the fourth gear 113 to rotate respectively, so as to drive the first crushing roller 110 and the second crushing roller 112 to crush the raw materials entering the interior of the body 101 multiple times, thereby improving the crushing effect on the raw materials.

[0032] Working principle: First, the raw materials to be ground are put into the interior of the machine body 101 through the feeding port 102. The rotation of the first motor 105 drives the first gear 111 to rotate. The rotation of the first gear 111 drives the second gear 107 to rotate. The rotation of the second gear 107 drives the third gear 109 and the fourth gear 113 to rotate. The rotation of the third gear 109 and the fourth gear 113 drives the first connecting shaft 108 and the second connecting shaft 114 to rotate. The rotation of the first connecting shaft 108 and the second connecting shaft 114 drives the first crushing roller 110 and the second crushing roller 112 to rotate, thereby crushing the raw materials entering the interior of the machine body 101 multiple times to improve the crushing effect on the raw materials. At the same time, when the raw materials enter the machine body 101, some raw materials will first come into contact with the first baffle 301, blocking this part of the offset raw materials, so that the raw materials first come into contact with the first screening plate 308. Under the action of the first screening plate 308, the raw materials are screened for the first time. The raw materials that meet the requirements will not enter the interior of the first crushing roller 110 under the diversion of the first diversion plate 307, thereby reducing the amount of raw materials entering the interior of the first crushing roller 110 and improving the working efficiency of the first crushing roller 110. The larger raw materials will continue to move on the surface of the first screening plate 308 until they enter the interior of the first crushing roller 110 for the first crushing. And during the movement of the raw materials, through the setting of the second baffle 303, the raw materials with too fast rolling speed can be blocked to prevent them from failing to enter the interior of the first crushing roller 110 for crushing. The raw materials after being crushed by the first crushing roller 110 will be screened for the second time under the action of the second screening plate 304. Among them, the raw materials that meet the requirements will not enter the interior of the second crushing roller 112 under the diversion of the second diversion plate 305, and the remaining raw materials will move into the interior of the second crushing roller 112 for the second crushing. Finally, after being screened by the third screening plate 306, they move to the bottom of the inner cavity of the machine body 101. The raw materials that meet the requirements will come into contact with the surface of the filter plate 302 after the screening is completed, removing the impurities and dust carried inside the raw materials, thereby improving the purity and cleanliness of the product. During the use of the first screening plate 308, if the raw materials are blocked inside the first screening plate 308, the second motor 201 can be driven to drive the fixed shaft 206 to rotate. The rotation of the fixed shaft 206 drives the wire reel 207 to rotate. The rotation of the wire reel 207 drives the traction wire 202 to be wound. The winding of the traction wire 202 drives the guide plate 211 to move. During the movement of the guide plate 211, it will slide inside the guide groove 209, thereby guiding the movement of the guide plate 211 to prevent the position of the guide plate 211 from shifting during the movement. The movement of the guide plate 211 drives the dredging roller 203 to move. The movement of the dredging roller 203 drives the dredging rod 210 to move. And when the dredging roller 203 comes into contact with the blocked raw materials,It will drive the dredging rod 210 to rotate under the support of the movable shaft 212, so that the dredging rod 210 can be driven to rotate on the surface of the first screening plate 308 to dredge the blocked raw materials inside the first screening plate 308. And when the dredging roller 203 is not in use, the dredging roller 203 can be moved to the leftmost side by winding the traction wire 202, so as to prevent the dredging roller 203 from blocking the normal movement of the raw materials.,

[0033] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
