Abstract
Description
Technical Field
[0001] This invention relates to the field of crushing technology, and in particular to a crushing and grinding device for processing red bean paste that can be screened and peeled. Background Technology
[0002] Dried red beans, as a grain crop rich in protein, dietary fiber, and various trace elements, have a wide range of applications in the food processing industry, such as in making red bean paste, red bean powder, red bean cakes, and other foods. Typically, a crusher is used to crush and grind the dried red beans, utilizing the mechanical force generated during the grinding process to separate the red bean skins from the kernels. The skins and kernels are then discharged separately through the equipment's separation structure, thus completing the peeling process. This process is widely adopted by food processing companies due to its ease of operation and relatively high peeling efficiency.
[0003] However, current technologies for crushing, grinding, and peeling dried red beans still have many technical shortcomings that urgently need to be addressed in practical applications. Firstly, in the collection of red bean skins, existing technologies generally employ two collection methods: the first is direct discharge, where the separated red bean skins are directly discharged from the equipment outlet into the production environment. Because red bean skins are lightweight, they easily generate dust during discharge, polluting the air in the production workshop. The second method is filter bag collection, where filter bags are tied to the red bean skin outlet of the equipment to intercept and collect the skins. While this method alleviates the dust dispersion problem to some extent, long-term use... During the process, red bean skins gradually accumulate inside the filter bag, causing blockage of the filter bag pores. When the filter bag becomes blocked to a certain extent, the stability of its connection with the outlet decreases, and the filter bag is prone to falling off. To avoid blockage and falling off, operators need to frequently replace the filter bag, increasing labor intensity and production costs. Secondly, in the pretreatment stage before grinding and peeling dried red beans, existing technologies generally lack a dedicated screening and impurity removal structure. During the harvesting, drying, storage, and transportation of dried red beans, impurities inevitably get mixed in. When these impurities enter the crusher for grinding along with the dried red beans, they cause changes in the gap between the grinding parts, affecting the grinding accuracy and peeling effect.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0037] Example 1, referring to Figures 1-14 This is the first embodiment of the present invention. This embodiment provides a crushing and grinding device for processing red bean paste that can be screened and peeled. It includes a main structure 1, including a crushing box 11. A crushing component 12 is provided at the top of the inner cavity of the crushing box 11. A first guide plate 13 is fixedly connected to the bottom of the inner cavity of the crushing box 11. A second guide plate 14 is provided at the bottom of the first guide plate 13. An installation plate 15 is fixedly connected to one side of the surface of the crushing box 11. A screening frame 16 is provided at the top of the installation plate 15. A screening component 17 is provided on one side of the screening frame 16.
[0038] The crushing box 11 creates a closed working space, and the crushing component 12 at the top provides the core power for crushing and grinding red beans, realizing the crushing of red beans and the initial separation of skin and kernel. The first guide plate 13 and the second guide plate 14 at the bottom form a guiding channel to ensure that the crushed material is transported in an orderly manner and avoids accumulation and blockage. The mounting plate 15 provides stable support for the screening frame 16. The screening frame 16 and the screening component 17 work together to form a pre-treatment screening structure, which can achieve the filtration of impurities before processing.
[0039] The collection component 2 includes a fan hood 21 connected to one side of the crushing box 11, a fan 22 fixedly connected to one side of the fan hood 21, a collection box 23 connected to the other side of the crushing box 11, an exhaust pipe 24 connected to one side of the collection box 23, a filter plate 25 fixedly connected to the inner cavity of the exhaust pipe 24, a self-cleaning component 26 provided on one side of the filter plate 25, a slag discharge port 27 connected to the bottom of the collection box 23, a sealing block 28 provided in the inner cavity of the slag discharge port 27, a triggering component 29 provided on one side of the sealing block 28, and a backflushing component 210 provided on one side of the triggering component 29.
[0040] The hood 21 and the fan 22 work together to form a directional airflow, which accurately guides the lightweight bean curd sheets into the collection box 23, avoiding workshop pollution caused by direct discharge. The filter plate 25 in the exhaust pipe 24 intercepts bean curd sheet debris and prevents dust from leaking out with the airflow. The self-cleaning component 26 can clean the surface deposits of the filter plate 25 in real time, replacing the traditional filter bag and reducing the replacement frequency. The slag discharge port 27 at the bottom of the collection box 23 is used to centrally discharge bean curd sheets. The sealing block 28 realizes the opening and closing of the slag discharge port 27 as needed. The trigger component 29 and the backflushing component 210 form a linkage mechanism to simultaneously complete the deep cleaning of the filter plate 25 during slag discharge.
[0041] Example 2, refer to Figures 1-14 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0042] Specifically, the crushing component 12 includes a motor 121 fixedly connected to the other side of the surface of the crushing box 11. The output shaft of the motor 121 is fixedly connected to a first crushing cylinder 122. A second crushing cylinder 123 is provided on one side of the first crushing cylinder 122. Both the first crushing cylinder 122 and the second crushing cylinder 123 are located in the inner cavity of the crushing box 11 and are rotatably connected to the crushing box 11. Both sides of the first crushing cylinder 122 and the second crushing cylinder 123 penetrate the crushing box 11 and are rotatably connected to a housing 124. The surface of the housing 124 is fixedly connected to the crushing box 11. The first crushing cylinder 122 and the second crushing cylinder 123 are meshed by a first gear 125.
[0043] The motor 121 provides the power source, driving the first grinding cylinder 122 to rotate. Then, the meshing transmission of the first gear 125 drives the second grinding cylinder 123 to rotate in the opposite direction, forming a grinding effect of opposing crushing. Compared with a single grinding structure, it can break the red beans into two halves more evenly. At the same time, the friction between the two cylinders enhances the separation of skin and kernel. The shell 124 supports the two ends of the first grinding cylinder 122 and the second grinding cylinder 123 to ensure rotational stability. This symmetrical double-cylinder grinding structure makes the red beans more evenly stressed during the grinding process, avoiding the problem of incomplete grinding and residue. It lays a good foundation for the subsequent screening and collection of bean skins. At the same time, the gear transmission ensures that the speed of the two cylinders is matched, improving the grinding accuracy.
[0044] Specifically, the screening component 17 includes a second gear 171 fixedly connected to the surface of the second crushing cylinder 123, a third gear 172 meshing on one side of the second gear 171 and rotatably connected to the housing 124, a movable rod 173 rotatably connected to the surface of the third gear 172, sliders 174 on both sides of the mounting plate 15, a slider 174 on one side rotatably connected to the movable rod 173, and a sliding plate 176 fixedly connected to the top of the slider 174 and located at the bottom of the screening frame 16.
[0045] Using the rotational power of the second crushing cylinder 123, the second gear 171 drives the third gear 172 to rotate, which in turn converts the movable rod 173 into a reciprocating push-pull motion, thereby driving the slider 174 to slide along the slide groove 175 of the mounting plate 15; the sliding plate 176 at the top of the slider 174 drives the screening frame 16 to reciprocate synchronously, causing the red beans in the frame to tumble continuously, thus achieving effective separation of impurities from the red beans; the reciprocating motion screening method can greatly improve screening efficiency and quickly separate impurities of different particle sizes.
[0046] Specifically, a coarse screen plate 177 is fixedly connected to the top of the inner cavity of the screening frame 16. One side of the coarse screen plate 177 penetrates the screening frame 16 and extends to the outside of the screening frame 16. A fine screen plate 178 is fixedly connected to the bottom of the coarse screen plate 177. One side of the fine screen plate 178 penetrates the screening frame 16 and the crushing box 11 and communicates with the inner cavity of the crushing box 11. A discharge plate 179 is fixedly connected to the bottom of the fine screen plate 178. One side of the discharge plate 179 penetrates the screening frame 16 and extends to the outside of the screening frame 16.
[0047] The coarse sieve plate 177 at the top of the inner cavity of the screening frame 16 first intercepts large-sized impurities in the red beans. The intercepted impurities can be directly cleaned through one side of the screening frame 16. The fine sieve plate 178 at the bottom of the coarse sieve plate 177 performs secondary filtration of small-sized impurities. The double screening ensures the purity of the raw materials. One side of the fine sieve plate 178 passes through the screening frame 16 and the crushing box 11 and is connected to the inner cavity, so that the screened pure red beans can directly enter the crushing box 11 for grinding, reducing secondary pollution during material transfer. The discharge plate 179 at the bottom of the fine sieve plate 178 can concentrate and discharge the small impurities intercepted by the fine sieve plate 178. This graded screening structure filters impurities of different particle sizes in a targeted manner, avoiding changes in the gap between the grinding parts after the impurities enter the crushing box 11, thereby ensuring the grinding accuracy and peeling effect.
[0048] Specifically, the self-cleaning component 26 includes a rotating shaft 261 rotatably connected to the filter plate 25, a fan blade 262 fixedly connected to one side of the surface of the rotating shaft 261, a cleaning plate 263 fixedly connected to the other side of the surface of the rotating shaft 261, a sleeve 264 rotatably connected to the surface of the rotating shaft 261, a bracket 265 rotatably connected to the surface of the sleeve 264, and fixedly connected to the inner cavity of the exhaust pipe 24.
[0049] After the filter plate 25 inside the exhaust duct 24 intercepts bean curd scraps, the airflow will drive the fan blade 262 to rotate, which in turn drives the rotating shaft 261 to rotate synchronously. The cleaning plate 263 on the surface of the rotating shaft 261 will rotate accordingly, scraping and cleaning the debris accumulated on the surface of the filter plate 25, realizing the simultaneous operation of "ventilation and cleaning". The sleeve 264 and the bracket 265 cooperate to support the rotating shaft 261, ensuring the stability of the rotation process and preventing the cleaning plate 263 from colliding with the filter plate 25.
[0050] Specifically, the trigger 29 includes a vertical plate 291 fixedly connected to the bottom of the screening frame 16, a lifting plate 292 at the bottom of the vertical plate 291, a guide block 293 fixedly connected to one side of the lifting plate 292, a guide groove 294 on the surface of the crushing box 11, a first spring 295 fixedly connected to the bottom of the guide block 293 and fixedly connected to the inner cavity of the guide groove 294, a sliding plate 176 and a mounting plate 15 passing through the bottom of the vertical plate 291 and a pulley 296 fixedly connected thereto, and a first fixing rod 297 fixedly connected to the bottom of the lifting plate 292. Both sides of the first fixed rod 297 are slidably connected to swing plates 298. A second fixed rod 299 is provided on one side of the first fixed rod 297 and is slidably connected to the swing plates 298. A rotating rod 2910 is rotatably connected to the surface of the swing plates 298 and is fixedly connected to the crushing box 11. A bending rod 2911 is fixedly connected to the bottom of the second fixed rod 299 and is fixedly connected to the sealing block 28. A support block 2912 is fixedly connected to the surface of the bending rod 2911. A support groove 2913 is opened on the surface of the crushing box 11 and cooperates with the support block 2912.
[0051] When red beans are added to the screening frame 16, it moves downward under force, causing the vertical plate 291 to press down on the lifting plate 292. This causes the guide block 293 to move down along the guide groove 294 and compress the first spring 295. The first fixed rod 297 drives the swing plate 298 to swing around the rotating rod 2910, which in turn pulls the bending rod 2911 upward through the second fixed rod 299, causing the sealing block 28 to close the slag discharge port 27, ensuring that there is no leakage during the bean skin collection stage. The support block 2912 and the support groove 2913 work together to improve the stability of the bending rod 2911. When the screening frame 16 is emptied and rises, the first spring 295 resets and drives the lifting plate 292 to rise. Subsequently, the linkage structure triggers the sealing block 28 to move down and open the slag discharge port 27. Thus, the weight of the material can be used to automatically open and close the slag discharge port 27, ensuring that the bean skin is collected completely before being discharged.
[0052] Specifically, limit rods 2914 are fixedly connected to all four sides of the bottom of the screening frame 16. A second spring 2915 is fixedly connected to the bottom of the limit rod 2914. A limit sleeve 2916 is fixedly connected to the bottom of the second spring 2915 and is slidably connected to the limit rod 2914. The limit sleeve 2916 is embedded in the inner cavity of the sliding plate 176. A limit switch 1761 is fixedly connected to the top of the sliding plate 176.
[0053] The limiting rod 2914 at the bottom of the screening frame 16 cooperates with the limiting sleeve 2916 to guide the lifting and lowering of the screening frame 16. The second spring 2915 is compressed when red beans are added and provides a restoring force after the material is emptied. When the screening frame 16 moves down to contact the limit switch 1761 at the top of the sliding plate 176, the motor 121 and the fan 22 are triggered to start, and the crushing, grinding and bean skin collection operations begin. When the material is emptied, the second spring 2915 drives the screening frame 16 to rise and disengage from the limit switch 1761, triggering the time relay to delay the shutdown of the motor 121 and the fan 22. Thus, through the combination of mechanical structure and electrical control components, intelligent control of "starting with material and delaying shutdown without material" can be achieved, ensuring that the crushing and grinding process is completely completed before stopping the machine, avoiding the unprocessed residual material due to premature shutdown. At the same time, the reset structure allows the screening frame 16 to quickly return to its initial state, improving the continuous operation efficiency of the equipment.
[0054] It should be noted that the limit switch 1761 and the time relay are both existing technologies, which are clearly known to those skilled in the art, and will not be elaborated here.
[0055] Specifically, a first hanging bracket 2917 is fixedly connected to the other side of the lifting plate 292. A through groove 2918 is opened on the surface of the crushing box 11 and cooperates with the first hanging bracket 2917. A cavity 2919 is opened in the inner wall of the crushing box 11. A third spring 2920 is fixedly connected to one side of the cavity 2919. A half frame 2921 is fixedly connected to one side of the third spring 2920. A cam 2922 is rotatably connected to the inner cavity of the half frame 2921. A torsion spring 2923 is fixedly connected to the surface of the crushing box 11. One side of the torsion spring 2923 is fixedly connected to the inner cavity of the half frame 2921. A second hanger 2924 is provided at the bottom of the first hanger 2917 and is fixedly connected to the second guide plate 14. Both sides of the second guide plate 14 are fixedly connected to the support blocks 2925. The inner cavity of the crushing box 11 is provided with a groove 2926. A fourth spring 2927 is fixedly connected to the bottom of the support block 2925 and is fixedly connected to the inner cavity of the groove 2926.
[0056] When the first bracket 2917 moves down with the lifting plate 292, it will simultaneously push the second guide plate 14 down. When the first bracket 2917 contacts the cam 2922, it can swing downward and retract into the cavity 2919. After the first bracket 2917 and the cam 2922 separate, the cam 2922 returns to its original position under the action of the torsion spring 2923. When the first spring 295 returns to its original position and drives the first bracket 2917 to rise, the cam 2922 can block the first bracket 2917 from rising, keeping the sealing block 28 closed. At this time, the return force of the first spring 295 alone is insufficient to push the cam 2917. 922; The second guide plate 14 is supported by the cooperation of the support blocks 2925 and the support groove 2926 on both sides. The fourth spring 2927 provides the reset force. After the red beans are completely discharged, the fourth spring 2927 drives the second guide plate 14 to rise. The second bracket 2924 pushes the first bracket 2917, compresses the third spring 2920, and causes the cam 2922 and the half frame 2921 to move laterally and retract. After the obstruction is released, the lifting plate 292 resets and the slag discharge port 27 can be opened. Thus, the timing of slag discharge can be controlled by the material discharge status to ensure that the red beans are completely discharged before slag discharge.
[0057] Specifically, the backflush member 210 includes a connecting rod 2101 hinged to one side of the sealing block 28, a through groove 2102 opened at the bottom of the exhaust pipe 24, the top of the connecting rod 2101 passing through the through groove 2102 and hinged to a drive sleeve 2103, a drive rod 2104 slidably connected to the inner cavity of the drive sleeve 2103, a side plate 2105 rotatably connected to one side of the drive rod 2104 and fixedly connected to the inner cavity of the exhaust pipe 24, a drive block 2106 fixedly connected to the inner wall of the drive sleeve 2103, a drive groove 2107 opened on the surface of the drive rod 2104 and cooperating with the drive block 2106, a fourth gear 2108 fixedly connected to the other side of the drive rod 2104, a fifth gear 2109 meshing at the top of the fourth gear 2108 and fixedly connected to the sleeve 264.
[0058] When the blocking block 28 moves down to open the slag discharge port 27, it drives the connecting rod 2101 to pull the drive sleeve 2103 to slide along the drive rod 2104. The drive block 2106 cooperates with the drive groove 2107 to make the drive rod 2104 rotate. The fourth gear 2108 drives the fifth gear 2109 to rotate, which in turn makes the sleeve 264 rotate synchronously. The sleeve 264 drives the rotating shaft 261 to reverse, so that the fan blade 262 generates a reverse airflow that blows towards the filter plate 25. Combined with the rotation of the cleaning plate 263 to scrape, a dual cleaning effect of "backwashing + scraping" is formed.
[0059] Specifically, the surface of the rotating shaft 261 is provided with a groove 21010, the inner cavity of the groove 21010 is rotatably connected with a locking block 21011, the surface of the locking block 21011 is fixedly connected with a fifth spring 21012, and is fixedly connected with the inner cavity of the groove 21010, and the inner wall of the sleeve 264 is provided with a locking groove 21013.
[0060] A locking block 21011 is installed in the groove 21010 on the surface of the rotating shaft 261. The fifth spring 21012 provides a reset force for the locking block 21011. The slot 21013 on the inner wall of the sleeve 264 cooperates with the locking block 21011. When the self-cleaning component 26 is working, the airflow of the fan 22 drives the fan blade 262 to reverse. The locking block 21011 retracts due to the contact between the slope and the slot 21013, and does not drive the sleeve 264 to rotate. When the backflushing component 210 is working, the sleeve 264 rotates so that the slot 21013 engages with the locking block 21011, driving the rotating shaft 261 to rotate forward to achieve backflushing. Thus, the one-way locking structure ensures that the self-cleaning and backflushing cleaning links operate independently and do not interfere with each other, ensuring both the real-time cleaning effect of the self-cleaning component 26 during normal operation and the deep cleaning effect of the backflushing component 210 during slag discharge.
[0061] Working principle: During the pre-treatment screening stage, after the dried red beans are put into the screening frame 16, the vertical plate 291 moves downward under the action of the gravity of the material, which in turn pushes the lifting plate 292 and the guide block 293 to move downward along the guide groove 294 and compress the first spring 295. At the same time, the screening frame 16 drives the limiting rod 2914 to slide into the limiting sleeve 2916 and compress the second spring 2915 until the screening frame 16 contacts the limit switch 1761 at the top of the sliding plate 176, triggering the motor 121 and the fan 22 to start. During this process, the lifting plate 292 will synchronously drive the first hanging frame 29 17 moves down and pushes the second bracket 2924 down. Then, the second bracket 2924 pushes the second guide plate 14 down, so that the support blocks 2925 on both sides of the second guide plate 14 move down along the support groove 2926 and compress the fourth spring 2927. When the first bracket 2917 moves down to contact the cam 2922, it will push the cam 2922 to swing down and retract into the cavity 2919 to avoid interfering with the downward movement of the first bracket 2917. After the first bracket 2917 continues to move down and separates from the cam 2922, the cam 2922 will automatically reset under the elastic force of the torsion spring 2923.
[0062] During crushing and grinding, the motor 121 drives the first crushing cylinder 122 to rotate, and through the meshing of the first gear 125, drives the second crushing cylinder 123 to rotate in the opposite direction, crushing and separating the red beans entering the crushing box 11 by friction; at the same time, the second crushing cylinder 123 drives the second gear 171 to rotate, and through the meshing of the third gear 172, causes the movable rod 173 to pull the slider 174 to slide along the slide groove 175, driving the sieve frame 16 to reciprocate; after the red beans in the sieve frame 16 pass through the coarse sieve plate 177 to intercept large impurities and the fine sieve plate 178 to filter small impurities, they enter the crushing box 11 through the discharge plate 179, and the impurities are discharged from the exposed ends of the two sieve plates respectively.
[0063] The crushed red beans and bean skins are conveyed through the first guide plate 13 and the second guide plate 14. The airflow generated by the blower 22 blows the bean skins into the collection box 23 through the wind hood 21. The whole bean skins fall to the bottom of the collection box 23 due to gravity, while the debris is carried by the airflow to the exhaust pipe 24 and intercepted by the filter plate 25. At the same time, the airflow drives the fan blades 262 to rotate, so that the rotating shaft 261 drives the cleaning plate 263 to scrape off the debris on the surface of the filter plate 25, realizing real-time self-cleaning.
[0064] After the red beans in the screening frame 16 are completely emptied, the second spring 2915 releases its elastic force to drive the limit rod 2914 to reset, causing the screening frame 16 to rise and disengage from the limit switch 1761, triggering the time relay to start the delayed shutdown program, ensuring that the equipment thoroughly completes the grinding and peeling of the residual materials; at the same time, the first spring 295 releases its elastic force to drive the guide block 293, the lifting plate 292 and the first bracket 2917 to rise synchronously. At this time, the reset cam 2922 will block the first bracket 2917, and the reset force of the first spring 295 alone is not enough to push the cam 2922 to move, so the lifting plate 292 cannot be fully reset, and the sealing block 28 remains closed.
[0065] After the motor 121 and fan 22 stop according to the delayed program, the bean skins have entered the collection box 23, and the red beans remaining on the surface of the second guide plate 14 have been completely discharged. At this time, the fourth spring 2927 releases its elastic force to drive the support block 2925 to rise along the support groove 2926, so that the second guide plate 14 rises synchronously and pushes the first hanger 2917 through the second hanger 2924. At this time, the combined force of the first spring 295 and the fourth spring 2927 overcomes the elastic force of the third spring 2920, pushing the cam 2922 and the half frame 2921 to move laterally and retract into the cavity 2919, releasing the obstruction to the first hanger 2917. Subsequently, the lifting plate 292 is fully reset, driving the bending rod 2911 to move down, so that the sealing block 28 opens the slag discharge port 27.
[0066] When the blocking block 28 moves down, it will drive the connecting rod 2101 to pull the drive sleeve 2103 to slide along the drive rod 2104. Through the cooperation of the drive block 2106 and the drive groove 2107, the drive rod 2104 will rotate. Through the meshing transmission of the fourth gear 2108 and the fifth gear 2109, the sleeve 264 will rotate. The sleeve 264 will drive the rotating shaft 261 to rotate forward through the snapping action of the slot 21013 and the snapping block 21011. This will cause the fan blade 262 to generate a reverse airflow that blows towards the filter plate 25. Combined with the scraping action of the rotating cleaning plate 263, a double cleaning effect is formed, blowing the debris remaining on the surface of the filter plate 25 into the collection box 23. Finally, it will be discharged from the slag discharge port 27 along with the whole bean skin.

[0068] Specifically, the surface of the mounting plate 15 is provided with a groove 175, which cooperates with the slider 174.
