[0018] like Figure 1 As shown, as a preferred embodiment of the present invention, the synchronous crushing mechanism 100 includes an inclined plate 1 3, an inclined plate 2 4, a crushing gear 1 5 and a crushing gear 2 6; The inclined plate 1 3 and the inclined plate 2 4 are fixedly mounted on the inner wall of the box body 1, and there is a gap between the inclined plate 1 3 and the inclined plate 2 4; A crushing gear 1 5 and a crushing gear 2 6 are respectively installed at the bottom of the inclined plate 1 3 and the inclined plate 2 4 in the box body 1 , and the crushing gear 1 5 and the crushing gear 2 6 are driven by independently arranged motors.

[0019] In one embodiment of the present invention, the raw material falls into the box body 1 through the filling port 2, and is crushed along the gap between the inclined plate 1 3 and the inclined plate 2 4 by the arranged crushing gear 1 5 and the crushing gear 2 6. The crushed raw material continues to move downward under the action of gravity.

[0020] like Figure 1 and Figure 2As shown, as another preferred embodiment of the present invention, the directional rolling mechanism 200 includes a folding plate 8, a diamond plate 9, a protrusion 10, a protrusion 2 11, a guide rod 12 and a material guide trough 13; The folding plate 8 is fixedly mounted on the inner wall of the box body 1, a protrusion 10 is arranged on the upper surface of the folding plate 8, and a material guide groove 13 is also opened in the middle of the folding plate 8; A guide rod 12 is installed in the guide trough 13 , and a rhombus plate 9 is fixedly connected to the top of the guide rod 12 . A second protrusion 11 cooperating with the first protrusion 10 is provided at the bottom of the rhombus plate 9 .

[0021] In one embodiment of the present invention, when the guide rod 12 is lifted and lowered by force, the guide rod 12 pulls the diamond plate 9 to move synchronously, the top end of the diamond plate 9 can accelerate the movement of the raw material, and the raw material falls between the folding plate 8 and the diamond plate 9. When the diamond plate 9 is lifted and lowered, the protrusion 2 11 at the bottom end is driven to lift and lower synchronously, and the protrusion 2 11 is combined with the protrusion 1 10 to realize the crushing of the raw material between the folding plate 8 and the diamond plate 9.

[0022] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the elastic drive mechanism 300 includes a fixed plate 14, a positioning column 15, a movable plate 16, a cross bar 17 and an elastic support member 18; The fixed plate 14 is fixedly mounted on the longitudinal rotating shaft 7, and a positioning column 15 is fixedly connected to the upper surface of the fixed plate 14; A cross bar 17 is slidably installed in the box body 1, the cross bar 17 is connected to an elastic support member 18 arranged in the box body 1, and the middle part of the cross bar 17 is fixedly connected to the guide rod 12; The cross bars 17 on both sides are connected by a movable disk 16 , and a curved groove matching with the positioning column 15 is arranged inside the movable disk 16 .

[0023] In one example of the present invention, when the longitudinal rotating shaft 7 rotates driven by the motor, the longitudinal rotating shaft 7 drives the fixed disk 14 and the positioning column 15 arranged thereon to rotate synchronously. When the positioning column 15 slides in the curved groove set at the bottom end of the movable disk 16, it can push the movable disk 16 and the cross bar 17 to slide in the height direction along the inner wall of the box body 1. At the same time, the elastic support member 18 is deformed under the force.

[0024] like Figure 1 and Figure 4 As shown, as another preferred embodiment of the present invention, the screening and discharging mechanism 400 includes a receiving plate 19, a sieve plate 21, a receiving plate 22 and a discharging port 23; The receiving plate 19 and the sieve plate 21 are fixedly connected to the inner wall of the box body 1, and the receiving plate 19 and the sieve plate 21 are arranged alternately; A receiving plate 22 is installed at the bottom of the screen plate 21 inside the box body 1, and a discharge port 23 is opened on the side of the box body 1 to facilitate the discharge of the screened raw materials.

[0025] In one embodiment of the present invention, the crushed raw material falls on the surface of the receiving plate 19 and moves downward along the surface of the receiving plate 19 under the action of gravity. When passing the end of the receiving plate 19, it falls on the screen plate 21 and is screened by the holes set on the screen plate 21. The raw material smaller than the hole diameter passes through the screen plate 21 and falls downward on the receiving plate 22, and is finally discharged outward through the discharge port 23, while the raw material larger than the hole diameter moves downward along the surface of the screen plate 21.

[0026] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the circulation mechanism 500 includes a transverse rotating shaft 1 24, a groove 26, a transverse rotating shaft 27, a pulley 28, a synchronous belt 29, a spiral plate 30, a discharge port 31 and a housing 32; The transverse rotating shaft 1 24 and the transverse rotating shaft 2 27 are both rotatably mounted on the box body 1, the transverse rotating shaft 1 24 is connected to the longitudinal rotating shaft 7 through the bevel gear set 25, and a pulley 28 is installed on the same side of the transverse rotating shaft 1 24 and the transverse rotating shaft 2 27, and adjacent pulleys 28 are connected through a synchronous belt 29; The bottom plate 20 is provided with a groove 26, and a spiral plate 30 is installed on the second transverse rotating shaft 27 to facilitate material feeding; An outer shell 32 is installed on the outer side of the box body 1 , and a plurality of discharge ports 31 are opened on the box body 1 at the bottom end of the outer shell 32 .

[0027] In one embodiment of the present invention, after the raw material falls to the bottom of the bottom plate 20, the longitudinal rotating shaft 7 drives the transverse rotating shaft 1 24 to rotate through the set bevel gear set 25, and the transverse rotating shaft 1 24 drives the transverse rotating shaft 2 27 to rotate along the box body 1 through the arranged synchronous belt 29. The spiral plate 30 rotates synchronously with the transverse rotating shaft 27 to transport the crushed raw material outward and pass through the discharge port 31 into the outer shell 32. When the raw material in the outer shell 32 passes through the return port 33, it can fall into the box body 1. At the same time, the aperture of the discharge port 31 can be increased or cancelled under appropriate circumstances.

[0028] In summary, the raw material passes through the filling port 2 and falls into the box body 1, and along the gap between the inclined plate 1 3 and the inclined plate 2 4, the raw material is crushed by the arranged crushing gear 1 5 and the crushing gear 2 6. The crushed raw material falls on the top of the diamond plate 9 under the action of gravity, and continues to move between the folding plate 8 and the diamond plate 9. The external motor drives the longitudinal rotating shaft 7 to rotate, and the longitudinal rotating shaft 7 drives the fixed plate 14 and the positioning column 15 arranged thereon to rotate synchronously. When the positioning column 15 slides in the curved groove set at the bottom end of the movable plate 16, it can push the movable plate 16 and the transverse plate 16 to rotate. The rod 17 slides in the height direction along the inner wall of the box body 1. At the same time, the elastic support member 18 is deformed by the force, and the guide rod 12 pulls the diamond plate 9 to move synchronously. The top of the diamond plate 9 can accelerate the movement of the raw material, and the raw material falls between the folding plate 8 and the diamond plate 9. When the diamond plate 9 is lifted, the protrusion 11 at the bottom is lifted synchronously. The protrusion 11 and the protrusion 10 can realize the rolling work of the raw material between the folding plate 8 and the diamond plate 9. The rolled raw material falls on the surface of the receiving plate 19 and moves downward along the surface of the receiving plate 19 under the action of gravity. The raw materials move along the surface of the sieve plate 21, and when passing through the end of the receiving plate 19, they fall on the sieve plate 21, and are screened by the holes set on the sieve plate 21. The raw materials smaller than the hole diameter pass through the sieve plate 21 and fall downward on the receiving plate 22, and finally pass through the discharge port 23 to be discharged outward, while the raw materials larger than the hole diameter move downward along the surface of the sieve plate 21. After the raw materials fall to the bottom of the bottom plate 20, the longitudinal rotating shaft 7 drives the transverse rotating shaft 1 24 to rotate through the bevel gear set 25, and the transverse rotating shaft 1 24 drives the transverse rotating shaft 2 27 to rotate along the box body 1 through the arranged synchronous belt 29, and the spiral plate 30 As the horizontal rotating shaft 27 rotates synchronously, the crushed raw materials are transported outward and pass through the discharge port 31 into the outer shell 32. When the raw materials in the outer shell 32 pass through the return port 33, they can fall into the box body 1. The device has the characteristics of high crushing efficiency and consistent volume of crushed particles. During the crushing process, the raw materials can not only be crushed but also crushed, and the accumulation of raw materials can be effectively avoided, thereby improving the processing speed. At the same time, the whole process has a high degree of automation, and the crushing, crushing, screening, discharge and circulation work can be completed without human participation.
