[0015] Please see Figure 1-6 This embodiment provides a technical solution: a multi-stage pulverizing device for spice processing with fine screening function, including a pulverizing chamber 1, a grinding chamber 2 at the lower end of the pulverizing chamber 1, a screening disc 13 between the pulverizing chamber 1 and the grinding chamber 2 (the pulverizing chamber 1, the grinding chamber 2 and the screening disc 13 are connected by threaded limit bolts that are evenly distributed, the screening disc 13 is a disc, and the disc has evenly distributed screening holes inside), a controller 15 is provided on the right side of the grinding chamber 2, the input end of the controller 15 is electrically connected to an external power supply, a feed hopper 14 is provided at the upper end of the pulverizing chamber 1 (the feed hopper 14 is fixedly connected to the feed inlet at the upper end of the pulverizing chamber 1), and also includes a bidirectional shearing mechanism 3; The bidirectional shearing mechanism 3 includes a rotating shaft 31, rotating rods 32, a turntable 33, and a transverse shearing assembly 37. The turntable 33 is rotatably connected to the upper end of the crushing chamber 1 (the turntable 33 is located above the feed inlet at the upper end of the crushing chamber 1). The rotating shaft 31 is fixedly connected to the middle of the turntable 33. The rotating rods 32 are rotatably connected to the inside of the turntable 33. The outer surfaces of the rotating shaft 31 and the rotating rods 32 are provided with evenly distributed shearing blades 4. The lower end of the rotating shaft 31 is provided with the transverse shearing assembly 37. The transverse shearing assembly 37 also includes a fixed column 371, a fixed chamber 372, an annular seat 373, a transverse rod 374, a fixed gear ring 375, and a gear 376. The fixed column 371 is connected to the lower end of the rotating shaft 31 by evenly distributed bolts. A fixed chamber 372 is fixedly connected to the lower end of the outer surface of column 371. An annular notch is provided in the middle of the fixed chamber 372. An annular seat 373 is rotatably connected inside the annular notch. Evenly distributed transverse rods 374 are rotatably connected between the middle of the annular seat 373 and the inner wall of the crushing chamber 1. Gears 376 are fixedly connected to the ends of the three transverse rods 374 near the center of the fixed chamber 372. A fixed gear ring 375 is fixedly connected to the bottom wall of the fixed chamber 372. All three gears 376 mesh with the fixed gear ring 375. Evenly distributed shearing blades 4 are also fixedly connected to the outer surface of the transverse rods 374. The bidirectional shearing mechanism 3 also includes a transmission gear 34, an internal gear ring 35, and a motor 36. The transmission gears 34 are all fixedly connected to the upper end of the rotating rod 32. The internal gear ring... 35 is fixedly connected to the upper end of the inner wall of the crushing chamber 1. All three transmission gears 34 are meshed with the internal gear ring 35. (The three transmission gears 34 and the internal gear ring 35 are located between the upper surface of the turntable 3 and the top wall of the crushing chamber 1, thus protecting the three transmission gears 34 and the internal gear ring 35 and preventing spice raw materials from adhering to the outer surfaces of the three transmission gears 34 and the internal gear ring 35, affecting the transmission effect of the planetary gears). Motor 36 is located at the upper end of the crushing chamber 1. The lower end of the output shaft of motor 36 is fixedly connected to the upper end of the rotating shaft 31. The input end of motor 36 is electrically connected to the output end of controller 15. Spices raw materials are added to the interior of the crushing chamber 1 through the feed hopper 14, and then motor 36 is operated by controller 15. The output shaft of motor 36... The rotation drives the rotating shaft 31 to rotate, which in turn drives the turntable 33 to rotate, which in turn drives the three rotating rods 32 to rotate. All three rotating rods 32 rotate around the central axis of the rotating shaft 31. The lateral rotation of the rotating shaft 31 and the three rotating rods 32 drives the adjacent, evenly distributed shearing blades 4 to rotate laterally, thus achieving the shearing and pulverizing of the spice raw materials. Simultaneously, the rotation of the rotating rods 32 around the central axis of the rotating shaft 31 drives the adjacent transmission gears 34 to rotate around the central axis of the rotating shaft 31. The transmission gears 34 rotate under the action of the internal gear ring 35, thereby causing the rotating rods 32 to rotate on their own axes during their revolution. The rotation of the three rotating rods 32 is opposite to the rotation direction of the rotating shaft 31, thus achieving the lateral relative shearing of the spices.Simultaneously, the rotation of the rotating shaft 31 drives the fixed column 371 to rotate, which in turn drives the fixed chamber 372 to rotate. Under the limiting action of the transverse rod 374, the annular seat 373 and the fixed chamber 372 rotate relative to each other. The rotation of the fixed chamber 372 drives the fixed gear ring 375 to rotate, which in turn drives the three gears 376 to rotate. The rotation of the gears 376 drives the adjacent transverse rod 374 to rotate, and the rotation of the transverse rod 374 drives the adjacent shearing blade 4 to rotate. This achieves vertical shearing and pulverization of the spice raw materials, as well as multi-directional shearing and pulverization, effectively improving the pulverization efficiency of the spice raw materials. Specifically: Inclined plates 11 are fixedly connected to the upper ends of the inner walls on both sides of the grinding chamber 2; the lower ends of the two inclined plates 11 are fixedly connected to the upper ends of the arc-shaped sieve plate 12 (the arc-shaped sieve plate 12 is an arc-shaped plate, and the interior of the arc-shaped plate has evenly distributed screening holes; the diameter of the screening holes inside the arc-shaped sieve plate 12 is smaller than the diameter of the screening holes inside the screening disc 13); a main grinding roller 5 is rotatably connected inside the grinding chamber 2; and three evenly distributed secondary grinding rollers 6 are rotatably connected inside the grinding chamber 2. All three secondary grinding rollers 6 are installed in conjunction with the main grinding roller 5. All components are installed to fit the upper surface of the arc-shaped sieve plate 12. A protective chamber 7 is provided at the rear end of the grinding chamber 2. The rear ends of the main grinding roller 5 and the three secondary grinding rollers 6 extend into the interior of the protective chamber 7. A driven gear 9 is fixedly connected to the rear end of each of the three secondary grinding rollers 6. A main gear 8 is fixedly connected to the rear end of the main grinding roller 5. All three driven gears 9 are meshed with the main gear 8. (The three driven gears 9 and the main gear 8 are all located inside the protective chamber 7. The protective chamber 7 protects the driven gears 9 and the main gear 8, preventing external impurities from affecting the transmission effect of the driven gears 9 and the main gear 8.) The grinding chamber 2 is equipped with a second motor 10 at its front end. The rear end of the output shaft of the second motor 10 is fixedly connected to the front end of the main grinding roller 5. The input end of the second motor 10 is electrically connected to the output end of the controller 15. The spice raw material, which has been pulverized to a certain degree, enters the interior of the grinding chamber 2 through the screening holes inside the screening disc 13. Under the guiding action of the inclined plate 11, the pulverized spice raw material moves towards the arc-shaped screen plate 12. At the same time, the controller 15 enables the second motor 10 to operate. The rotation of the output shaft of the second motor 10 drives the main grinding roller 5 to rotate, and the rotation of the main grinding roller 5 drives the main gear 8 to rotate. The main gear 8 rotates, driving three driven gears 9 to rotate. The rotation of each driven gear 9 drives the adjacent secondary grinding rollers 6 to rotate. The main grinding roller 5 and the secondary grinding rollers 6 rotate in opposite directions. The main grinding roller 5 and the three secondary grinding rollers 6 squeeze each other to grind the crushed spice raw materials. At the same time, the three secondary grinding rollers 6 grind the crushed spice raw materials under the support of the arc-shaped screen plate 12. The spice raw materials ground to a certain degree fall into the discharge hopper at the lower end of the grinding chamber 2 through the screening holes inside the arc-shaped screen plate 12 for centralized discharge of the spice raw materials.

[0016] The working principle of the multi-stage pulverizing device for spice processing with fine screening function provided by this utility model is as follows: During operation, the operator first places the pulverizing chamber 1, the grinding chamber 2, and other mechanisms stably in the horizontal working area. After stable placement, the operator adds spice raw materials into the pulverizing chamber 1 through the feed hopper 14. Then, the controller 15 drives the motor 36 to operate. The output shaft of the motor 36 rotates, driving the rotating shaft 31 to rotate. The rotating shaft 31 rotates, driving the turntable 33 to rotate. The turntable 33 rotates, driving the three rotating rods 32 to rotate. The rotating rods 32 all rotate around the central axis of the rotating shaft 31. The lateral rotation of the rotating shaft 31 and the three rotating rods 32 drives the adjacent, evenly distributed shearing blades 4 to rotate laterally. The process achieves shearing and pulverizing of spice raw materials. Simultaneously, the rotation of the rotating rod 32 around the central axis of the rotating shaft 31 drives the adjacent transmission gears 34 to rotate around the central axis of the rotating shaft 31. Each transmission gear 34 rotates under the action of the internal gear ring 35, thus causing the rotating rod 32 to rotate during its revolution. The rotation directions of the three rotating rods 32 are opposite to the rotation direction of the rotating shaft 31, thereby achieving lateral relative shearing of the spices. Simultaneously, the rotation of the rotating shaft 31 drives the fixed column 371 to rotate, which in turn drives the fixed chamber 372 to rotate. Under the limiting action of the transverse rod 374, the ring seat 373 and the fixed chamber 372 rotate relative to each other. The rotation of the fixed chamber 372 then drives the fixed gear ring 375 to rotate. The fixed gear ring 375 rotates, driving three gears 376 to rotate. The rotation of gears 376 drives the adjacent transverse rods 374 to rotate, and the rotation of transverse rods 374 drives the adjacent shearing blades 4 to rotate, achieving vertical shearing and pulverizing of the spice raw materials. Simultaneously, it achieves multi-directional shearing and pulverizing of the spice raw materials, effectively improving the pulverizing efficiency. The pulverized spice raw materials enter the grinding chamber 2 through the screening holes inside the screening disc 13. Under the guiding action of the inclined plate 11, the pulverized spice raw materials move towards the arc-shaped screen plate 12. Simultaneously, the controller 15 activates the second motor 10. The output shaft of the second motor 10 rotates, driving the main grinding roller 5 to rotate. The rotation of the main grinding roller 5 drives the main gear 8 to rotate. The rotation of roller 8 drives three driven gears 9 to rotate, and the rotation of each driven gear 9 drives the adjacent secondary grinding rollers 6 to rotate. The rotation directions of the main grinding roller 5 and the secondary grinding rollers 6 are opposite. The main grinding roller 5 and the three secondary grinding rollers 6 squeeze each other to grind the crushed spice raw materials. At the same time, the three secondary grinding rollers 6 grind the crushed spice raw materials under the support of the arc-shaped screen plate 12. The spice raw materials ground to a certain degree fall into the discharge hopper at the lower end of the grinding chamber 2 through the screening holes inside the arc-shaped screen plate 12 for centralized discharge of spice raw materials. Through multi-directional shearing crushing and grinding of spice raw materials, and under the screening action of the screening disc 13 and the arc-shaped screen plate 12, the spice raw materials are finely screened during the crushing process.

[0017] It is worth noting that the controller 15 disclosed in the above embodiments controls the operation of motor 36 and motor 10 using methods commonly used in the prior art.
