[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of an integrated crushing device for starch processing, comprising a crushing box 1. Two grooves 3 are formed at the top of the crushing box 1, providing space for fixing bars 4. Fixing bars 4 are slidably connected to the inner walls of both grooves 3, fixing servo motors 5 to the fixing bars 4. The same servo motor 5 is fixedly connected to adjacent sides of the two fixing bars 4, providing power for the rotation of a stirring shaft 7. A coupling 6 is fixedly connected to the output end of the servo motor 5, transmitting torque and providing shock absorption. A stirring shaft 7 is fixedly connected to the bottom end of the coupling 6, transmitting power. Multiple stirring rods 8 are fixedly connected to the top of the outer wall of the stirring shaft 7, through which raw materials are fed... The initial crushing process involves multiple crushing blades 9 fixedly connected to the bottom of the outer wall of the stirring shaft 7, which thoroughly crush the raw materials. A scraper 11 is fixedly connected to the middle of the outer wall of the stirring shaft 7, which allows raw materials of suitable size to enter below the filter screen 10. A filter screen 10 is fixedly connected to the middle of the inner wall of the crushing box 1, which is used to screen raw materials of appropriate size. A vibrator 12 is fixedly connected to the bottom of the filter screen 10, which can prevent raw materials from getting stuck on the filter screen 10. A top cover 13 is rotatably connected to the top of the crushing box 1, which can protect the raw materials and components inside the crushing box 1 and prevent impurities from contaminating them. A discharge mechanism 2 is provided at the bottom of the crushing box 1 for rapid discharge.
[0033] Specifically, open the top cover 13, place the starch raw material to be crushed into the crushing chamber 1, close the top cover 13 to ensure the crushing chamber 1 is in a closed state to prevent impurities from entering and contaminating the raw material, start the servo motor 5 and transmit power to the stirring shaft 7 through the coupling 6, causing the stirring shaft 7 to start rotating. Multiple stirring rods 8 at the top of the stirring shaft 7 rotate together with the stirring shaft 7, performing preliminary crushing of the raw material in the crushing chamber 1, breaking down larger pieces of raw material. While the stirring rods 8 are performing preliminary crushing, multiple pulverizing blades 9 at the bottom of the stirring shaft 7 are also rotating at high speed. As the raw material falls, it passes through the action area of the pulverizing blades 9 and is pulverized. The crusher 9 further cuts and pulverizes the raw material to achieve complete crushing. The raw material particles after initial crushing are of different sizes. As the stirring shaft 7 rotates, the scraper 11 in the middle pushes the raw material falling on the filter screen 10, so that the qualified raw material falls through the mesh of the filter screen 10 and into the bottom of the filter screen 10. At the same time, the vibrator 12 is activated to make the filter screen 10 shake, so as to prevent the raw material from getting stuck on the filter screen 10 and ensure the smooth progress of the screening process. Larger unqualified raw materials continue to remain on the filter screen 10 and are continuously pushed by the scraper 11 until they are further crushed or meet the conditions for passing through the filter screen 10.
[0034] Reference Figure 2 , Figure 5 and Figure 6 The discharge mechanism 2 includes a conical bottom plate 201, which allows qualified raw materials to fall smoothly from the crushing box 1, reducing material residue in the device. The top of the conical bottom plate 201 is fixedly connected to the bottom of the crushing box 1. A vibrator 202 is fixedly connected to the right side of the inner wall of the conical bottom plate 201. The vibrator 202 prevents raw materials from sticking to the inner wall of the conical bottom plate 201. A discharge pipe 203 is threadedly connected to the bottom of the inner wall of the conical bottom plate 201, through which raw materials are discharged. A one-way valve 204 is fixedly connected to the top of the inner wall of the discharge pipe 203. The one-way valve 204 can prevent... To prevent raw material backflow, two motor mounts 205 are fixedly connected to the inner wall of the discharge pipe 203. The motor mounts 205 are used to fix the motor protective shell 206 and the micro motor 207. The same motor protective shell 206 is fixedly connected to the left and right adjacent sides of the two motor mounts 205. The motor protective shell 206 is used to protect the micro motor 207. The micro motor 207 is fixedly connected to the top of the inner wall of the motor protective shell 206. The micro motor 207 provides power for the rotation of the spiral blade 208. The output end of the micro motor 207 is fixedly connected to the spiral blade 208, which enables the raw material to fall smoothly.
[0035] Specifically, under the influence of gravity, qualified starch raw materials slide down the inner wall of the crushing chamber 1 onto the conical bottom plate 201. The inclined design of the conical bottom plate 201 allows the raw materials to naturally concentrate towards the bottom along the conical surface, reducing the amount of raw materials remaining at the bottom of the crushing chamber 1. The vibration generated by the vibrator 202 is transmitted to the inner wall of the conical bottom plate 201, loosening the raw materials adhering to it and preventing adhesion or accumulation due to the stickiness or friction of the raw materials. This further ensures that the raw materials move smoothly towards the inlet of the discharge pipe 203. When the raw materials reach the discharge... When the material enters the discharge pipe 203, the one-way valve 204 only allows the material to flow from the inlet of the discharge pipe 203 to the outlet, preventing the material from flowing back to the crushing box 1 or moving in the opposite direction in the discharge pipe 203, thus ensuring the one-wayness and stability of the discharge process. The micro motor 207 is turned on, and the micro motor 207 outputs power to drive the spiral blade 208 to rotate. The rotation of the spiral blade 208 generates axial thrust, which pushes the material entering the discharge pipe 203 along the axial direction of the discharge pipe 203, so that the material is discharged from the outlet of the discharge pipe 203 at a stable speed and flow rate.
[0036] Reference Figure 1 , Figure 2 and Figure 3 A limiting ring 14 is fixedly connected to the middle of the inner wall of the crushing box 1. Multiple limiting blocks 15 are also fixedly connected to the middle of the inner wall of the crushing box 1. The limiting ring 14 and the limiting blocks 15 restrict the position of the filter screen 10. Threaded grooves 16 are provided on the opposite sides of the two fixing bars 4, allowing bolts 17 to penetrate part of the crushing box 1. The fixing bars 4 are fixed in position by the threaded grooves 16 and bolts 17. Bolts 17 are threaded onto the inner walls of both threaded grooves 16. Two pins 20 are fixedly connected to the top left side of the crushing box 1, and two pins 20 are fixedly connected to the left side of the top cover 13. The top cover 13 is opened and closed via two pivots 20 and two pivots 19. A locking lug 21 is fixedly connected to the top right side of the crushing box 1, and a latch 22 is fixedly connected to the right side of the top cover 13. The position of the top cover 13 is fixed by the locking lug 21 and the latch 22. A rubber pad 18 is fixedly connected to the bottom of the top cover 13. The rubber pad 18 adopts a ring design and can prevent impurities from entering the device. A control panel 23 is fixedly connected to the middle right side of the crushing box 1. The control panel 23 is electrically connected to the servo motor 5, the vibrator 12 and the micro motor 207 respectively.
[0037] Specifically, before the device is put into operation, the operator can connect the device to a specific mobile device via wireless technology. This allows the operator to control the servo motor 5, vibrator 12, and micro motor 207 via the control panel 23, and also to remotely control the device via the mobile device. The filter screen 10 is placed into the crushing chamber 1. The limiting ring 14 initially limits the position of the filter screen 10 from below, and multiple limiting blocks 15 further secure the filter screen 10 from above, ensuring that the filter screen 10 is fixed in the middle of the inner wall of the crushing chamber 1 and does not shake or shift during subsequent crushing and screening. The fixing strip 4 with the servo motor 5 is slid along the slide groove 3 at the top of the crushing chamber 1 to the appropriate position. Then, the bolt 17 is passed through the corresponding position in the crushing chamber 1, and... Thread the screws 16 on the fixing strip 4 and tighten the bolts 17 to fix the position of the fixing strip 4, ensuring that the servo motor 5 is stably installed on the top of the crushing box 1. Align the rotating shaft 19 on the left side of the top cover 13 with the pin 20 on the top left side of the crushing box 1, so that the top cover 13 can open and close around the pin 20. At the same time, check that the annular rubber gasket 18 at the bottom of the top cover 13 plays a sealing role when the top cover 13 is closed, preventing impurities from entering the device. When putting in raw materials, open the top cover 13 and put the starch raw materials to be crushed into the crushing box 1. Then close the top cover 13 so that the latch 22 on the right side of the top cover 13 engages with the latch 21 on the top right side of the crushing box 1, thereby fixing the position of the top cover 13 and ensuring that the device is in a closed state during operation.
[0038] Working Principle: After the servo motor 5 is started, the motor transmits torque stably to the stirring shaft 7 through the coupling 6. The coupling 6 not only ensures lossless power transmission but also buffers vibration and impact during equipment operation, protecting the motor and stirring shaft 7. When the stirring shaft 7 rotates, the stirring rod 8 at the top rotates at high speed, using mechanical collision to initially break larger lumps in the starch raw material into smaller particles. After crushing, the raw material particles are of mixed sizes. As the stirring shaft 7 rotates, the scraper 11 continuously scrapes the surface of the filter screen 10, pushing the raw material falling on the filter screen 10 forward. The filter screen 10 has a mesh size set according to the particle size standard required for starch processing. Raw material particles that meet the particle size requirements are pushed by the scraper 11 through the mesh and fall below the filter screen 10, while larger, unqualified raw materials are... The material is intercepted above the filter screen 10. To prevent the material from getting stuck on the filter screen 10 and affecting the screening efficiency, the vibrator 12 causes the filter screen 10 to vibrate at high frequency, which causes the material stuck in the mesh to come off and ensures the smooth flow of the filter screen 10. The unqualified material left on the filter screen 10 is pushed back to the crushing area by the scraper 11 and is crushed again by the stirring rod 8 and the crushing knife 9 until the particle size meets the requirements and passes through the filter screen 10. While the stirring rod 8 is performing initial crushing, the crushing knife 9 at the bottom of the stirring shaft 7 operates at high speed. The material after initial crushing falls under the action of gravity and enters the working area of the crushing knife 9. The crushing knife 9 cuts the material and further refines the particles, so as to achieve complete crushing of starch raw materials and meet the particle size requirements of starch processing.
[0039] Furthermore, after the qualified starch raw materials have been crushed and screened, they slide down the inner wall of the crushing chamber 1 due to their own gravity. At this time, the inclined design of the conical bottom plate 201 effectively reduces the residue of raw materials at the bottom of the crushing chamber 1, allowing the raw materials to move naturally and smoothly towards the inlet of the discharge pipe 203. When the vibrator 202 is activated, if the raw materials adhere to the inner wall of the conical bottom plate 201 due to stickiness or friction, the vibration changes the force between the raw materials and the inner wall, allowing the raw materials to move smoothly towards the inlet of the discharge pipe 203 under the continued action of gravity, avoiding the problem of poor discharge caused by adhesion or accumulation. When the raw material flows from the inlet of the discharge pipe 203 to the outlet, the one-way valve 204 effectively prevents the raw material from flowing back into the crushing box 1 or flowing in reverse within the discharge pipe 203, ensuring the stability and continuity of the discharge process. The micro motor 207 outputs power to drive the spiral blades 208 to rotate. The spiral shape of the spiral blades 208 generates an axial thrust on the raw material entering the discharge pipe 203, allowing the raw material to be distributed more evenly within the discharge pipe 203, thereby discharging from the outlet of the discharge pipe 203 at a stable speed and flow rate. This effectively overcomes the gravity and friction of the raw material during the discharge process, ensuring the high efficiency and stability of the discharge.
