Description

Technical Field

[0001] This invention relates to the field of feed crushing and processing technology, specifically to a feed crusher and its control method. Background Technology

[0002] Feed is a general term for the food of animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. In the process of feed processing and production, crushers are often used to crush the raw materials to facilitate animal absorption and digestion.

[0003] In existing technologies, the crushing process of feed raw materials using a crusher often involves only screening the crushed feed particles by a single-layer filter screen. Oversized particles are repeatedly crushed, while particles smaller than or equal to the standard feed particle size pass through the filter screen and are discharged as finished feed. While this crushing process effectively breaks down the feed raw materials, it results in the production of some excessively small powdery feed particles. This powdery feed, mixed in with the finished feed, is more likely to generate dust during transportation or animal feeding, potentially affecting the health of workers and animals. Furthermore, in the feeding of chickens, ducks, and geese, for example, the powdery feed... Small feed particles can reduce the feeding efficiency of chickens, ducks, and geese. Furthermore, excessively small feed particles may cause them to swallow too quickly, leaving insufficient time for saliva to moisten and soften them. Smaller particles may also reduce the secretion of digestive juices in the mouth and stomach, increasing the burden on the digestive system and thus affecting the health of the chickens, ducks, and geese. Additionally, feed residue can accumulate on the crushing rollers during prolonged operation, reducing the gap between the crushing teeth and hindering effective contact and impact with the feed particles. This can lead to an increase in the proportion of powdery feed in the finished product, resulting in lower quality and higher production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a feed processing crusher and its control method, solving the problem of how to screen and remove small feed particles generated during the crushing process of feed raw materials:

[0005] The objective of this invention can be achieved through the following technical solutions:

[0023] In one embodiment, the system further includes a weighing module comprising three weighing boxes, all of which are fixedly connected to the processing box and respectively cooperate with the discharge port, return port, and waste port. Each weighing box includes a rectangular side plate and a bottom plate, with the bottom plate rotatably connected to the rectangular side plate. A torsion spring and an electronic counter are mounted on the rotatable connecting shaft between the bottom plate and the rectangular side plate. Permanent magnets that attract each other are fixedly connected to the side of the bottom plate away from the torsion spring and the corresponding rectangular side plate.

[0024] A control module is fixedly connected to the processing box. The control module is used to control the feeding motor, the adjustable distance motor, the servo motor and the electric slide.

[0025] A control method for a feed processing crusher, the method comprising:

[0026] S1. Feed raw materials to be crushed and processed are added into the holding chamber through the feeding hopper, and the feeding motor and servo motor are controlled by the control module.

[0027] S2. The control module controls the pitch motor to rotate in the forward direction, driving another crushing roller to move at a preset speed at a constant speed from the farthest distance to the first crushing roller until the minimum distance is reached. The weighing module monitors the cumulative discharge of the discharge port, return port and waste port in real time, and analyzes and obtains the time node corresponding to the optimal distance between the two crushing rollers.

[0028] S3. Control the pitch motor to rotate in the opposite direction through the control module, and move the other crushing roller away from the first crushing roller at a preset speed until the distance between the two crushing rollers is the optimal distance and then stop.

[0029] S4. Analyze the cumulative discharge volume of the collected discharge port and waste port, and determine when the feed raw material processing conversion rate does not meet the standard. Control the feeding motor to stop working, switch the servo motor to intermittent working mode, and synchronously control the two electric slides to drive the cleaning teeth to move back and forth to clean the gap between adjacent crushing teeth. After cleaning, continue the crushing work.

[0030] Furthermore, in step S2, the process of analyzing and obtaining the time point corresponding to the optimal spacing between the two crushing rollers includes:

[0031] Drive another crushing roller to move towards the first crushing roller at a preset speed. The preset time point when the two crushing rollers have the maximum distance is t1, and the preset time point when the two crushing rollers have the minimum distance is t2.

[0032] Establish a rectangular coordinate system with the preset time interval [t1, t2] as the X-axis and the cumulative weighing values ​​collected by each weighing module as the Y-axis. Obtain a point graph of the cumulative discharge volume at the discharge port, return port, and waste port. Connect the points of the cumulative discharge volume at each discharge port sequentially with a smooth curve to obtain the curve Q of the cumulative discharge volume of large-particle feed discharged from the return port over time. s (t) Curve of cumulative discharge of pelleted feed from the discharge port over time W s The curve E of (t) and the cumulative discharge of small pellet feed from the waste outlet over time. s (t);

[0033]

[0034] The feed output rate f of the crusher is obtained by analysis and calculation using formula (1). s (t);

[0035] Among them, Q′ s (t) represents the discharge velocity curve of large-particle feed discharged from the return feed inlet, W′ s (t) is the discharge velocity curve of medium-sized pelleted feed discharged from the discharge port, E′ s (t) is the curve showing the change in the discharge rate of small-particle feed from the waste outlet;

[0036] Presumably, within the time interval [t1, t2], there exists a condition when t = t0;

[0037] f s (t0)=MAX{f s (t)} (2)

[0038] The feed output rate f of the crusher at time t0 was obtained by analysis and calculation using formula (2). s (t0);

[0039] Where, MAX{f s (t)} represents the feed output rate f of the crusher. s The maximum value of (t), i.e., when t = t0, indicates that the feed output rate of the crusher is the highest, and the corresponding distance between the two crushing rollers is the optimal spacing.

[0040] Furthermore, in step S4, the process of determining that the feed ingredient processing conversion rate does not meet the standard includes:

[0041] The feed raw material processing conversion rate during the crushing process is detected by the control module at a preset frequency.

[0042]

[0043] The feed ingredient processing conversion rate C was obtained by analyzing and calculating using formula (3). s ;

[0044] Among them, the preset time period [t] a , t b [E] represents the duration of a single detection of feed ingredient processing conversion rate by the control module. s (t b ) for t b The cumulative amount of small-particle feed discharged from the waste outlet at the specified time point, E s (t a ) for t a W is the cumulative amount of small-particle feed discharged from the waste outlet at the specified time point. s (t b ) for t b W is the cumulative amount of medium-sized pelleted feed discharged from the discharge port at the specified time point. s (t a ) for t a The cumulative amount of medium-sized pelleted feed discharged from the discharge port at the specified time point;

[0045] feed ingredient processing conversion rate C s Standard conversion rate C of pre-set feed ingredient processing abn Perform a comparison;

[0046] When C s ≤C abn If the feed raw material processing conversion rate is not up to standard, it is necessary to clean the gap between adjacent crushing teeth on the crushing roller.

[0047] Conversely, the crusher continuously processes and crushes the feed ingredients.

[0048] The beneficial effects of this invention are:

[0049] (1) The present invention uses a screening component in the screening chamber to screen and classify feed of different particle sizes. The feed is transported to different feed outlets according to different particle sizes. Large particles of feed are returned to the holding chamber for repeated crushing. Small particles of feed are screened to the bottom of the processing box and discharged through the outlet. Medium particles of feed are screened out and discharged through the outlet on the side wall of the processing box. In this way, small particles of feed generated during the crusher processing of feed raw materials can be screened and removed. The obtained feed consists of particles of appropriate size. During transportation or feeding, dust is not easily generated, which may affect the health of workers or animals. When used to feed chickens, ducks and geese, it is beneficial to the digestive system of chickens, ducks and geese.

[0050] (2) The present invention cleans the residual feed attached to the crushing component by means of a cleaning component at a preset frequency or by intelligent control, thereby ensuring the conversion rate of feed raw materials into qualified finished feed and reducing the production cost of feed.

[0051] (3) When the filter frame slides back and forth in the screening chamber, when the filter frame slides upward, it will drive the feed particles on the filter screen upward through the triangular baffle. When the filter frame moves downward, the feed particles driven by the triangular baffle will roll over the triangular baffle under its own inertia. Then, when it falls down by its own weight, it will be blocked by the triangular baffle. During the movement of the filter frame, the feed particles on the filter screen will roll a large distance on the filter screen, so that the feed particles are fully filtered by the filter screen, which improves the efficiency and probability of feed particles with a particle diameter less than or equal to the filter screen hole passing through the filter screen. The feed particles with a particle diameter greater than the filter screen hole will be gradually sent to the highest point of the corresponding filter frame under the sequential pushing action of each triangular baffle, and then discharged into the holding chamber through the return port or discharged from the processing box through the discharge port. The crushed feed can be fully screened according to different particle sizes, and the small particles of feed generated during the production process can be screened out from the medium-sized particles, ensuring the quality of the feed obtained from the processing production.

[0052] (4) In this invention, the entire process of another crushing roller moving towards one crushing roller at a preset speed is timed, and a curve Q is obtained showing the cumulative discharge amount of large-particle feed discharged from the return port as a function of time. s (t) Curve of cumulative discharge of pelleted feed from the discharge port over time W s The curve E of (t) and the cumulative discharge of small pellet feed from the waste outlet over time. s (t), and then the curve f of the feed output rate of the crusher as a function of time is obtained by analyzing and calculating using formula (1). s (t), which is the curve f of the feed output rate processed by the crusher over time within a preset time interval. s The maximum value of (t) is MAX{f s (t)}, the time node t0 corresponding to the optimal distance between the two crushing rollers is obtained by analysis, and then the control module controls the pitch adjustment motor to rotate in the opposite direction until t a After a certain time period, the distance between the two crushing rollers will reach the optimal distance. By maintaining the two crushing rollers at this distance, the feed raw material can be crushed with the best efficiency. The crusher can intelligently analyze feed raw materials of different particle sizes to obtain the optimal crushing efficiency, thereby improving the crushing efficiency of the crusher for feed raw materials.

[0053] (5) In this invention, the feed ingredients are obtained through analysis using formula (3) within a preset time period [t]. a ,t b Processing conversion rate C within the range s When there is any preset time period [t] a ,t b Processing conversion rate C within the range s Less than or equal to the preset standard conversion rate C for feed ingredient processing abn If the value of powdered feed produced during the crushing process exceeds the preset value, it indicates that the crusher may have accumulated feed residue on the crushing rollers during long-term operation. The cleaning teeth can be controlled by the control module to clean the feed residue on the crushing rollers. After cleaning, the crushing process can be restarted, thereby improving the feed raw material processing conversion rate, increasing the output of feed raw materials, and reducing the cost of feed raw materials consumed in the feed processing process.

[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] Please see Figures 1 to 11 As shown, in one embodiment, a feed processing crusher is provided, comprising:

[0070] Processing box 1, which is equipped with a material holding chamber 2, a crushing chamber 3 and a screening chamber 4;

[0071] The feeding assembly is located in the feeding chamber 2 and is used to transport the feed raw materials in the feeding chamber 2 to the crushing chamber 3;

[0072] The crushing component is located at the connection between the crushing chamber 3 and the screening chamber 4, and is used to crush and process feed raw materials.

[0073] The screening component, located inside the screening chamber 4, is used to screen and classify the processed feed according to different particle sizes and transport it to different feed outlets.

[0074] The cleaning components, located on both sides of the crushing components, are used to clean the residual feed adhering to the crushing components.

[0075] Through the above technical solution, this embodiment provides a feed processing crusher, including a processing box 1. The processing box 1 is provided with a holding chamber 2, a crushing chamber 3, and a screening chamber 4. During operation, the feed raw materials in the holding chamber 2 are conveyed to the crushing chamber 3 by a feeding component. Then, under the action of its own weight, the feed raw materials fall into the screening chamber 4 through the crushing chamber 3. During this process, the crushing component crushes the feed raw materials into feed of different particle sizes. After entering the screening chamber 4, the screening component in the screening chamber 4 screens and classifies the feed of different particle sizes. According to the different particle sizes, the feed is conveyed to different feed outlets for discharge. Among them, large particles of feed are returned to the holding chamber 2 for repeated crushing, small particles of feed are screened to the bottom of the processing box 1 and discharged through the outlet, and medium particles of feed are screened out and discharged through the processing box 1. The feed is discharged through the outlet on the side wall, which allows for the screening and removal of small feed particles generated during the processing of feed ingredients by the crusher. The resulting feed consists of appropriately sized particles, which are less likely to generate dust during transportation or feeding, thus minimizing the impact on the health of workers or animals. This feed is also beneficial for the digestive systems of chickens, ducks, and geese. However, as the crushing components continue to crush the feed ingredients, feed residue will adhere to the crushing components, leading to a narrowing of the gaps between the crushing components. This may result in an increased proportion of small feed particles generated during the crushing process, thereby reducing the conversion rate of feed ingredients into qualified finished feed. Therefore, the residual feed adhering to the crushing components can be cleaned by the cleaning components at a preset frequency or through intelligent control, thereby ensuring the conversion rate of feed ingredients into qualified finished feed and reducing feed production costs.

[0076] In one embodiment, the feeding assembly includes a feeding cylinder 21, the top of which is connected to the crushing chamber 3. A spiral lifting rod 22 is rotatably connected inside the feeding cylinder 21. A feeding motor 23 is fixedly connected to the processing box 1. The output end of the feeding motor 23 is fixedly connected to the spiral lifting rod 22. The lowest end of the spiral lifting rod 22 is immersed in the feed raw material in the feeding chamber 2. When the feeding motor 23 is controlled to work, the feeding motor 23 can drive the spiral lifting rod 22 to rotate. The spiral lifting rod 22 can lift the feed raw material and transport it to the crushing chamber 3 through the feeding cylinder 21.

[0077] The crushing assembly includes two crushing rollers 31. One crushing roller 31 is rotatably connected inside the processing box 1, and the other crushing roller 31 is rotatably connected to the adjusting mechanism. The two crushing rollers 31 cooperate with each other to crush feed materials passing through the gap between the two crushing rollers 31. The adjusting mechanism is used to adjust the distance between the two crushing rollers 31, which facilitates the crushing of feed materials of different particle sizes, such as soybeans and corn. During the crushing process, the distance between the two crushing rollers 31 will have a certain difference. Furthermore, the particle size of the same type of feed material may also vary due to the growth environment or variety. Adjusting the distance between the two crushing rollers 31 according to the particle size of the feed material during processing can effectively improve the crushing efficiency of the feed processing process and reduce the cost of feed materials.

[0078] The adjustment mechanism includes two L-shaped support plates 5, which are slidably connected to the two side walls of the processing box 1. The two ends of another crushing roller 31 are rotatably connected to the two L-shaped support plates 5. Fixed plates 11 are symmetrically fixedly connected to the two side walls of the processing box 1. Threaded rods 51 are threadedly connected to the fixed plates 11. One end of the threaded rod 51 is rotatably connected to the L-shaped support plate 5. Adjustment motors 12 are symmetrically slidably connected to the two side walls of the processing box 1. The output end of the adjustment motor 12 is fixedly connected to the other end of the threaded rod 51. When it is necessary to adjust the distance between the two crushing rollers 31, the two adjustment motors 12 can be controlled to rotate synchronously. The adjustment motors 12 drive the threaded rod 51 to rotate. Under the thread limit of the fixed plate 11, the threaded rod 51 and the adjustment motor 12 are driven to slide in the left and right directions during the rotation, thereby driving the L-shaped support plates 5 to slide on the side walls of the processing box 1, thereby adjusting the distance between the two crushing rollers 31.

[0079] The processing box 1 has symmetrical sliding windows 13 on both sides of the side wall. Two L-shaped support plates 5 are slidably connected to the corresponding sliding windows 13. Sliding baffles 52 are fixedly connected to both ends of the two L-shaped support plates 5. The sliding baffles 52 are embedded and slidably connected to both sides of the processing box 1. The sliding baffles 52 fixedly connected to both ends of the L-shaped support plates 5 can guide and block the sliding windows 13 during the sliding process of the L-shaped support plates 5, so as to prevent the L-shaped support plates 5 from falling off the side wall of the processing box 1, and also to prevent the feed from rolling out of the processing box 1 through the sliding windows 13.

[0080] The cleaning assembly includes two electric slides 6. One electric slide 6 is fixedly connected inside the processing box 1 and is located on one side of a crushing roller 31. The other electric slide 6 is fixedly connected at both ends to two L-shaped support plates 5 and is located on one side of another crushing roller 31. A slider 61 is installed on the electric slide 6, and a cleaning tooth 62 is fixedly connected to the slider 61.

[0081] Each of the two crushing rollers 31 has a number of crushing teeth 311 fixedly connected to it. The crushing teeth 311 of the two crushing rollers 31 cooperate with each other. The gap between the cleaning teeth 62 and the adjacent crushing teeth 311 is close. Both ends of the crushing rollers 31 are provided with toothless parts 312. During the cleaning process of the crushing rollers 31, the cleaning component can drive the slider 61 and the cleaning teeth 62 to move back and forth through the electric slide table 6. When the gap between the cleaning teeth 62 and the adjacent crushing teeth 311 is relatively aligned, the electric slide table 6 drives the cleaning teeth 62 to move and clean the gap between the adjacent crushing teeth 311, so as to achieve the purpose of cleaning the feed residue attached to the crushing rollers 31. When the crushing rollers 31 rotate, the cleaning teeth 62 can be aligned with the toothless parts 312 provided at both ends of the crushing rollers 31, which can avoid the collision between the crushing rollers 31 and the cleaning teeth 62 during the rotation.

[0082] The screening assembly includes two filter frames 7. One filter frame 7 has a medium-sized filter screen 71 fixedly connected to it, and the other filter frame 7 has a small-sized filter screen 72 fixedly connected to it. The two filter frames 7 are arranged inside the screening chamber 4 and divide the screening chamber 4 into a first chamber 41, a second chamber 42, and a third chamber 43 from top to bottom. One filter frame 7 is located above the other filter frame 7. The feeding chamber 2 and the screening chamber 4 are separated by a partition 14. The partition 14 has a return port 141 that communicates with the first chamber 41. The processing box 1 has a discharge port 15 that communicates with the second chamber 42 on its side wall, and a waste port 16 that communicates with the third chamber 43 on its bottom. During the process of filtering the crushed feed through the screening assembly... First, all feed pellets fall into the first chamber 41. Small and medium-sized feed pellets pass through the perforated filter screen 71 into the second chamber 42. Large feed pellets enter the holding chamber 2 through the return port 141 for repeated crushing. The small feed pellets in the second chamber 42 continue to pass through the perforated filter screen 72 into the third chamber 43. Medium-sized feed pellets are discharged through the discharge port 15. The small feed pellets in the third chamber 43 are discharged through the waste port 16. In this way, the crushed feed is fully screened according to different particle sizes, and the small feed pellets generated during the production process are screened out from the medium-sized feed pellets, ensuring the quality of the feed obtained from the processing.

[0083] A feeding hopper 17 is fixedly connected to the side wall of the processing box 1. The feeding hopper 17 is connected to the feeding chamber 2, and the feeding hopper 17 facilitates the addition of the feed raw materials to be processed into the feeding chamber 2.

[0084] A servo motor 19 is fixedly connected to the side wall of the processing box 1. The output end of the servo motor 19 is fixedly connected to a crushing roller 31. Two crushing rollers 31 are detachably connected to a transmission gear 32 that meshes with each other. During the rotation of the servo motor 19, the two crushing rollers 31 can be driven to rotate in opposite directions to fully crush the feed raw materials passing through the gap between the two crushing rollers 31. It should be noted that the distance between the two meshing transmission gears 32 can be finely adjusted to a certain extent. During the fine adjustment, the two transmission gears 32 have stable transmission. When the distance between the two crushing rollers 31 that needs to be adjusted is outside the finely adjustable distance of the transmission gears 32, the two transmission gears 32 can be replaced. In actual use, the crusher is equipped with multiple sets of transmission gears 32 of different specifications. During use, the corresponding specification of transmission gears 32 can be pre-installed according to the conventional size of the feed raw materials to be crushed. For example, when the feed raw materials are soybeans and corn, the transmission gears 32 used are of the corresponding specifications. A first guide wheel 33 is fixedly connected to the other end of the other crushing roller 31.

[0085] Both filter frames 7 are slidably connected within the screening chamber 4. The two ends of the filter frames 7 are limited vertically by the side walls of the processing box 1 and the partition plate 14. Several triangular baffles 73 are fixedly connected to each of the two filter frames 7. The cross-section of each triangular baffle 73 is a right-angled triangle. Both filter frames 7 are tilted, and the right-angled sides of the right-angled triangles on the triangular baffles 73 on the filter frames 7 all point towards the highest point of the filter frame 7. The first guide wheel 33 drives the two filter frames 7 to slide back and forth within the screening chamber 4 via a linkage mechanism. During the screening process, the feed particles falling onto the filter screen are distributed in a stepped manner due to the obstruction of the triangular baffles 73. When the filter frames 7 slide back and forth within the screening chamber 4, and tilt upwards, the triangular baffles 73 will push the feed particles on the filter screen towards the tilting direction. Driven diagonally upwards, when the filter frame 7 tilts downwards, the feed particles driven by the triangular baffle 73 will roll over the triangular baffle 73 under their own inertia. Then, when they fall due to their own weight, they will be blocked by the triangular baffle 73. During the movement of the filter frame 7, the feed particles on the filter screen will roll a large distance on the filter screen, so that the feed particles are fully filtered by the filter screen, increasing the efficiency and probability of feed particles with a diameter less than or equal to the filter screen opening passing through the filter screen. Feed particles with a diameter greater than the filter screen opening will be gradually sent to the highest point of the corresponding filter frame 7 under the sequential pushing action of each triangular baffle 73, and then discharged into the holding chamber 2 through the return port 141 or discharged from the processing box 1 through the discharge port 15.

[0086] The linkage mechanism includes a support shaft 8, which is rotatably connected to the screening chamber 4. A drive rod 81 is symmetrically fixedly connected to the support shaft 8. A swing sleeve 82 is slidably sleeved on the end of the drive rod 81 away from the support shaft 8. The end of the swing sleeve 82 away from the drive rod 81 is rotatably connected to the filter frame 7. One end of the support shaft 8 extends to the outside of the processing box 1 and is fixedly connected to an L-shaped connecting rod 83. A sliding column 84 is fixedly connected to the end of the L-shaped connecting rod 83 away from the support shaft 8. A rotating shaft 85 is rotatably connected to the side wall of the processing box 1. A cam 86 and a second guide wheel 88 are fixedly connected to the rotating shaft 85. A limit slide rail 87 is provided on the edge of the cam 86. The sliding column 84 is slidably connected within the limit slide rail 87. The first guide wheel 33 is connected via a transmission... The drive belt 89 is rotatably connected to the second guide wheel 88. During the rotation of the crushing roller 31, the first guide wheel 33 can be driven to rotate, which in turn drives the second guide wheel 88 to rotate through the drive belt 89. The cam 86 is driven to rotate through the rotating shaft 85. During the rotation of the cam 86, the L-shaped connecting rod 83 can be driven to swing back and forth with the support shaft 8 as the fulcrum through the cooperation of the limiting slide rail 87 and the sliding column 84. This drives the support shaft 8 to rotate back and forth at a preset angle. In this way, the drive rod 81, which is fixedly connected to the support shaft 8, will drive the two filter frames 7 to slide back and forth along the edge direction of the filter frame 7 in the screening chamber 4 through the sliding sleeve 82, thereby achieving the purpose of driving the two filter frames 7 to slide back and forth at an inclined angle.

[0087] It also includes a weighing module, which comprises three weighing boxes 9. All three weighing boxes 9 are fixedly connected to the processing box 1 and respectively cooperate with the discharge port 15, return port 141, and waste port 16. Feed particles discharged through the discharge port 15, return port 141, and waste port 16 fall into their corresponding weighing boxes 9. Each weighing box 9 includes a rectangular side plate 91 and a bottom plate 92. The bottom plate 92 is rotatably connected to the rectangular side plate 91. A torsion spring and an electronic counter are mounted on the rotatable connecting shaft between the bottom plate 92 and the rectangular side plate 91. Permanent magnets are fixedly connected to the side of the bottom plate 92 away from the torsion spring and the corresponding rectangular side plate 91. When the amount of feed particles falling into the weighing box 9 is small, its own weight cannot push the bottom plate 92 under the action of the permanent magnets and torsion springs. When the amount of feed particles falling into the weighing box 9 is large, its own weight cannot push the bottom plate 92 under the action of the permanent magnets and torsion springs. When the weight of the feed pellets in the weighing box 9 reaches a certain weight, it will push the base plate 92 under the action of permanent magnets and torsion springs. When the base plate 92 rotates, the mutually attracted permanent magnets will disengage, the attraction will decrease, and the base plate 92 will fully open under the weight of the feed pellets, so that all the feed pellets in the weighing box 9 will fall out. Then the base plate 92 will reset under the action of the torsion spring until the two permanent magnets contact, forming a weighing box 9 with a rated weighing capacity. In this way, the weighing box 9 will discharge once each time a rated weight of feed pellets is loaded. By counting the number of times the weighing box 9 is opened by the electronic counter installed on the weighing box 9, the cumulative weight of the discharged feed from the discharge port 15, return port 141, and waste port 16 can be collected.

[0088] A control module 18 is fixedly connected to the processing box 1. The control module 18 is used to control the feeding motor 23, the adjustable motor 12, the servo motor 19 and the electric slide table 6.

[0089] Please see Figure 12 As shown, in one embodiment, a control method for a feed processing crusher is provided. The method is used in a feed processing crusher and includes:

[0090] S1. Feed raw materials to be crushed and processed are added into the feeding chamber 2 through the feeding hopper 17, and the feeding motor 23 and servo motor 19 are controlled by the control module 18.

[0091] S2. The control module 18 controls the pitch motor 12 to rotate in the forward direction, driving another crushing roller 31 to move at a preset speed at a constant speed from the farthest distance to the first crushing roller 31 until the minimum distance is reached. The weighing module monitors the cumulative discharge amount of the discharge port 15, return port 141 and waste port 16 in real time, and analyzes and obtains the time node corresponding to the optimal distance between the two crushing rollers 31.

[0092] S3. Control the pitch motor 12 to rotate in the opposite direction through the control module 18, so that the other crushing roller 31 moves away from the first crushing roller 31 at a preset speed at a uniform speed until the distance between the two crushing rollers 31 is the optimal distance and then stops.

[0093] S4. Analyze the cumulative discharge volume of the collected discharge port 15 and waste port 16. If the feed raw material processing conversion rate does not meet the standard, control the feeding motor 23 to stop working, switch the servo motor 19 to intermittent working mode, and synchronously control the two electric slides 6 to work. Drive the cleaning teeth 62 to move back and forth to clean the gap between adjacent crushing teeth 311. After cleaning, continue crushing work.

[0094] Through the above technical solution, this embodiment provides a control method for a feed processing crusher. First, the feed raw materials to be crushed are added into the feeding chamber 2. The control module 18 controls the operation of the feeding motor 23 and the servo motor 19. The feeding motor 23 transports the feed raw materials in the feeding chamber 2 to the crushing chamber 3. The servo motor 19 drives two crushing rollers 31 to work, crushing the feed raw materials that have entered the screening chamber 4 through the crushing chamber 3. Then, the control module 18 controls the pitch motor 12 to rotate forward, driving the other crushing roller 31 at a preset speed. The crushing rollers move at a constant speed from the furthest distance towards one of the crushing rollers 31 until the minimum distance is reached. The furthest distance is the maximum distance that can be formed between the two crushing rollers 31 under the corresponding specification transmission gear 32. Specifically, it is the distance formed between the two crushing rollers 31 when the control motor 12 is working after the corresponding specification transmission gear 32 is installed and the two transmission gears 32 are brought close enough to achieve stable transmission. No actual measurement is required. The minimum distance is the minimum distance that can be formed between the two crushing rollers 31 under the corresponding specification transmission gear 32. Specifically, it is the minimum distance that can be formed when the corresponding specification transmission gears 32 mesh fully with each other. The distance between the two crushing rollers 31 at the optimal time does not require actual measurement. During this process, the cumulative output of the discharge port 15, return port 141, and waste port 16 is monitored in real time by the weighing module. The optimal distance between the two crushing rollers 31 is determined when the proportion of qualified finished feed discharged from the discharge port 15 is the highest during the processing of the feed raw materials. The optimal time point is analyzed and obtained. Then, the control module 18 controls the pitch adjustment motor 12 to rotate in the opposite direction, moving the other crushing roller 31 away from the first crushing roller 31 at a preset speed. The machine moves at a constant speed until the distance between the two crushing rollers 31 reaches the optimal distance corresponding to the time node analyzed in step S2, and then stops. This continuous crushing process of feed raw materials can achieve the optimal crushing efficiency of the feed motor 23 and servo motor 19 at this speed. It should be noted that the speed of the feed motor 23 and servo motor 19 during the operation of the crusher is preset manually. Generally, multiple speed levels are preset manually according to the specifications of the feed motor 23 and servo motor 19, which can facilitate the crushing and processing of feed raw materials of different materials based on experience.

[0095] Finally, during the crushing and processing of feed raw materials, the cumulative output of the collected discharge port 15 and waste port 16 is analyzed. It is determined that if the feed raw material processing conversion rate does not meet the standard, continuing to crush and process the feed raw material may produce more powdery feed, leading to an increase in feed production costs. Therefore, the feeding motor 23 is stopped, the servo motor 19 is switched to intermittent working mode, and the two electric slides 6 are controlled to work synchronously. The cleaning teeth 62 are driven to move back and forth to clean the gap between adjacent crushing teeth 311. Specifically, during the reciprocating movement of the cleaning teeth 62 driven by the electric slide 6, when the cleaning teeth 62 correspond to the toothless part 312 of the crushing roller 31 at both ends of the electric slide 6, the crushing roller 31 rotates at a preset angle under the drive of the servo motor 19. When the cleaning teeth 62 move in the middle of the electric slide 6, the crushing roller 31 does not rotate, and the cleaning teeth 62 scrape and clean the gap between adjacent crushing teeth 311.

[0096] In one embodiment, step S2, the process of analyzing the time point corresponding to obtaining the optimal spacing between the two crushing rollers 31, includes:

[0097] Drive another crushing roller 31 to move towards one crushing roller 31 at a preset speed. The preset time point when the two crushing rollers 31 have the maximum distance is t1, and the preset time point when the two crushing rollers 31 have the minimum distance is t2.

[0098] Establish a rectangular coordinate system with the preset time interval [t1, t2] as the X-axis and the cumulative weighing values ​​collected by each weighing module as the Y-axis. Obtain a point graph of the cumulative discharge amount from discharge port 15, return port 141, and waste port 16. Connect the points of the cumulative discharge amount from each discharge port sequentially with a smooth curve to obtain the curve Q of the cumulative discharge amount of large-particle feed discharged from return port 141 over time. s (t), Curve W of the cumulative discharge amount of medium-sized pelleted feed discharged from discharge port 15 over time. s The curve E shows the cumulative discharge amount of small pellet feed discharged from waste outlet 16 over time. s (t);

[0099]

[0100] The feed output rate f of the crusher is obtained by analysis and calculation using formula (1). s (t);

[0101] Among them, Q′ s (t) is the discharge velocity curve of large-particle feed discharged from return port 141, W′ s (t) is the discharge velocity curve of medium-sized pelleted feed discharged from discharge port 15, E s(t) is the curve showing the change in the discharge rate of small-particle feed from waste outlet 16;

[0102] Presumably, within the time interval [t1, t2], there exists a condition when t = t0;

[0103] f s (t0)=MAX{f s (t)} (2)

[0104] The feed output rate f of the crusher at time t0 was obtained by analysis and calculation using formula (2). s (t0);

[0105] Where, MAX{f s (t)} represents the feed output rate f of the crusher. s The maximum value of (t), i.e., when t = t0, is when the feed output rate of the crusher is the highest, and the corresponding distance between the two crushing rollers 31 is the optimal spacing.

[0106] Through the above technical solution, this embodiment provides a method for analyzing and obtaining the time node corresponding to the optimal distance between two crushing rollers 31. The method involves timing the entire process of one crushing roller 31 moving uniformly towards another crushing roller 31 at a preset speed, with the start time node being t1 and the end time node being t2. A rectangular coordinate system is established, with the preset time interval [t1, t2] as the X-axis and the cumulative weighing value collected by the three weighing boxes 9 as the Y-axis. A model is then created to obtain the curve Q showing the cumulative discharge amount of large-particle feed discharged from the return port 141 over time. s (t), Curve W of the cumulative discharge amount of medium-sized pelleted feed discharged from discharge port 15 over time. s The curve E shows the cumulative discharge amount of small pellet feed discharged from waste outlet 16 over time. s (t), where the cumulative output can be obtained by multiplying the number of times each weighing box 9 is opened by the electronic counter by the preset rated weighing weight of each weighing box 9 during the manufacturing process. The rated weighing weights of the three weighing boxes 9 can be the same, or the preset rated weighing weights of the weighing boxes 9 at different positions can be different. In addition, the two permanent magnets fixedly connected to the weighing box 9 can be replaced with an adjustable electromagnet and an iron plate, which makes it easier to adjust and calibrate the rated weighing weight of each weighing box 9. Then, the curve f of the feed output rate of the crusher processed by the crusher changing with time can be obtained by analyzing and calculating through formula (1). s (t), where Q′ s (t) is the discharge rate curve of large-particle feed discharged from return port 141. This can be obtained by analyzing the cumulative discharge amount of large-particle feed discharged from return port 141 over time. s Differentiating (t) yields W′ s(t) is the discharge rate curve of medium-sized pellets discharged from discharge port 15. This can be obtained by analyzing the cumulative discharge amount of medium-sized pellets discharged from discharge port 15 over time. s Differentiating (t) yields E′ s (t) is the discharge rate curve of small pellet feed discharged from waste outlet 16. It can be obtained by analyzing the cumulative discharge amount of small pellet feed discharged from waste outlet 16 over time. s (t) is differentiated to obtain the curve f of the feed output rate of the crusher as a function of time within a preset time interval. s The maximum value of (t) is MAX{f s (t)), obtain the corresponding time node t0, and thus analyze and obtain the time node corresponding to the optimal distance between the two crushing rollers 31;

[0107] It should be noted that in step S3, the control module 18 controls the pitch adjustment motor 12 to rotate in the opposite direction until the distance between the two crushing rollers 31 reaches the optimal distance, which is the process described by formula t. a =t2-t0 analysis and calculation to obtain the control of another crushing roller 31 to move away from the first crushing roller 31 at a preset speed t a After a certain period of time, the distance between the two crushing rollers 31 will reach the optimal distance. By maintaining the two crushing rollers 31 at this distance, the feed raw material can be crushed with the best efficiency. The crusher can intelligently analyze feed raw materials of different particle sizes to obtain the optimal crushing efficiency, thereby improving the crushing efficiency of the crusher for feed raw materials.

[0108] In one embodiment, step S4, determining that the feed ingredient processing conversion rate does not meet the standard, includes:

[0109] The feed raw material processing conversion rate during the crushing process is detected by the control module 18 at a preset frequency. The preset frequency can be obtained by preset based on experience.

[0110]

[0111] The feed ingredient processing conversion rate C was obtained by analyzing and calculating using formula (3). s ;

[0112] Among them, the preset time period [t] a , t b E represents the time interval between consecutive detections of feed ingredient processing conversion rate by the control module 18. s (t b ) for t b The cumulative amount of small pellet feed discharged from waste outlet 16 at the specified time point, E s (ta ) for t a The cumulative amount of small pellet feed discharged from waste outlet 16 at the specified time point, W s (t b ) for t b The cumulative amount of medium-sized pelleted feed discharged from discharge port 15 at the specified time point, W s (t a ) for t a The cumulative amount of medium-sized pelleted feed discharged from discharge port 15 at the specified time point, E s (t b E s (t a W s (t b ) and W s (t a All of these can be obtained through data collection and analysis by the weighing module;

[0113] feed ingredient processing conversion rate C s Standard conversion rate C of pre-set feed ingredient processing abn Perform a comparison;

[0114] When C s ≤C abn If the feed raw material processing conversion rate is not up to standard, it is necessary to clean the gap between adjacent crushing teeth 311 on the crushing roller 31.

[0115] Conversely, the crusher continuously processes and crushes the feed ingredients.

[0116] Through the above technical solution, this embodiment provides a method for detecting whether the feed raw material processing conversion rate meets the standard. The feed raw material is analyzed and obtained in a preset time period [t] using formula (3). a , t b Processing conversion rate C within the range s When there is any preset time period [t] a , t b Processing conversion rate C within the range s Less than or equal to the preset standard conversion rate C for feed ingredient processing abn If the number of powdered feed produced during the crushing process exceeds the preset value, it indicates that the proportion of powdered feed produced by the crusher exceeds the preset value. The reason for this phenomenon may be that feed residue will adhere to the crushing roller 31 during long-term operation. The control module 18 controls the cleaning teeth 62 to clean the feed residue attached to the crushing roller 31. After cleaning, the crushing work is restarted, thereby improving the feed raw material processing conversion rate, achieving the goal of increasing the output of feed raw materials, and reducing the cost of feed raw materials consumed in the feed processing process.

[0117] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
