Description

Technical Field

[0001] The present invention relates to the technical field of feed crushing and processing, and in particular to a crushing method and system for feed processing. Background Art

[0002] The continuous advancement of mechanical engineering technology has provided technical support for feed processing. The traditional feed crushing method is simple and inefficient. With the development of mechanical manufacturing technology and automation technology, automation technology has been widely used in feed production. Automation technology enables the various parameters of feed raw materials in the processing process to be accurately controlled according to actual conditions. Straw is a common and important raw material in feed. Straw with different moisture content has significant differences in physical properties. This difference will cause the straw raw material to block the feed inlet during crushing, affecting the stability of the feed processing crushing process. Therefore, improving the stability of the feed processing crushing process and the consistency of the crushed products is a technical problem that needs to be solved urgently.

At the same time, it can automatically repeat the crushing process of larger materials to ensure the crushing effect of the material.

[0004] The following problems also exist in the prior art:

[0005] The existing technology does not take into account that during the continuous production of large-scale feed, the difference in toughness of straw raw materials affects the feeding stability of the straw raw materials into the crushing mechanism. The existing technology cannot adaptively adjust the crushing processing method according to the actual toughness difference of the straw raw materials, which affects the stability of the feed processing crushing process and the consistency of the crushed products. Summary of the Invention

[0006] To this end, the present invention provides a crushing method and system for feed processing to overcome the problem that the existing technology cannot adaptively adjust the crushing processing method according to the actual toughness differences of straw raw materials, which affects the stability of the feed processing crushing process and the consistency of the crushed products.

[0007] To achieve the above-mentioned object, the present invention provides a crushing method and system for feed processing, comprising:

[0008] Obtaining straw raw materials required for feed components;

[0009] performing a pre-cutting process on the straw raw material, obtaining a cutter vibration characteristic parameter of the straw raw material during the pre-cutting process, and determining whether the straw raw material has abnormal toughness according to the cutter vibration characteristic parameter;

[0010] The straw raw materials with abnormal toughness are crushed and pre-processed, wherein the crushing and pre-processing includes flattening and squeezing the straw raw materials to obtain flat straw raw materials;

[0011] Obtain the change in discharge stability of straw raw materials with abnormal toughness before and after crushing pretreatment;

[0014] Or, adjusting the single feeding amount of the flat straw raw material;

[0015] The flat straw raw material is crushed in the crushing process adjustment manner to obtain a crushed product.

[0016] Furthermore, the process of obtaining the cutter vibration characteristic parameters includes:

[0017] In the process of pre-cutting the straw raw material by the cutter, the cutting trajectory is determined by taking the tip of the cutter as the trajectory capture point;

[0018] The displacement of the cutting trajectory in the length direction of the straw raw material is determined as the cutter vibration characteristic parameter.

[0019] Furthermore, determining whether the straw raw material has abnormal toughness includes:

[0020] If the cutter vibration characteristic parameter of the straw raw material does not meet the normal conditions of straw toughness, it is determined that the straw raw material has abnormal toughness;

[0021] If the cutter vibration characteristic parameters of the straw raw material meet the normal straw toughness conditions, it is determined that the straw raw material does not have abnormal toughness;

[0022] The normal condition for straw toughness is that the cutter vibration characteristic parameter of the straw raw material does not exceed a preset cutter vibration characteristic reference value.

[0023] Furthermore, the extrusion time and the extrusion pressure value for flat extrusion of the straw raw material are determined according to the cutter vibration characteristic parameters, the extrusion time is positively correlated with the cutter vibration characteristic parameters, and the extrusion pressure value is positively correlated with the cutter vibration characteristic parameters.

[0024] Furthermore, the change in discharge stability is determined based on a first discharge coefficient and a second discharge coefficient of the straw raw material with abnormal toughness before and after crushing pretreatment.

[0025] Furthermore, the process of determining the first discharge coefficient includes:

[0026] Obtaining the material output weight of the straw raw material during several preset monitoring cycles before the straw raw material is crushed and pre-processed;

[0027] The variance of the material output weight within the plurality of preset monitoring periods is determined as the first discharge coefficient.

[0028] Furthermore, the process of determining the second discharge coefficient includes:

[0029] Obtaining the material output weight of the straw raw material after crushing pretreatment for several preset monitoring cycles;

[0030] The variance of the material output weight within the plurality of preset monitoring periods is determined as the second discharge coefficient.

[0031] Further, determining whether the crushing pretreatment is effective includes:

[0032] If the change in the discharge stability of the straw raw material with abnormal toughness meets the effect judgment condition, it is determined that the crushing pretreatment is effective;

[0033] If the change in the discharge stability of the straw raw material with abnormal toughness does not meet the effect judgment condition, it is determined that the crushing pretreatment is invalid;

[0034] The effect judgment condition is that the difference between the first discharge coefficient and the second discharge coefficient exceeds a preset difference threshold.

[0035] Furthermore, the adjustment method for crushing the flat straw raw material is determined to include:

[0036] If the crushing pretreatment is effective, continue crushing the flat straw raw material in the manner of the crushing pretreatment;

[0037] If the crushing pretreatment is ineffective, the single feeding amount of the flat straw raw material is adjusted, and the single feeding amount is positively correlated with the difference between the first discharge coefficient and the second discharge coefficient.

[0038] Furthermore, the present invention also provides a crushing system for feed processing, comprising:

[0039] A pre-cutting module includes a cutting unit for pre-cutting the straw raw material, and a characteristic analysis unit for obtaining the cutter vibration characteristic parameters and determining whether the straw raw material has abnormal toughness;

[0040] A crushing pre-processing module, which is connected to the pre-cutting module and includes a flat extrusion unit for crushing and pre-processing the straw raw material, and a data analysis unit for obtaining a change in the discharge stability of the straw raw material with abnormal toughness;

[0041] A crushing module, connected to the crushing pre-treatment module, comprising a control unit and a crushing mechanism, wherein the control unit is used to determine whether the crushing pre-treatment is effective and to determine an adjustment method for crushing the flat straw raw material;

[0042] The crushing mechanism is used to crush the straw raw material to obtain crushed products.

[0043] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention obtains the straw raw materials required for feed components, pre-cuts the straw raw materials, obtains the cutter vibration characteristic parameters of the straw raw materials during the pre-cutting process, determines whether the straw raw materials have abnormal toughness according to the cutter vibration characteristic parameters, and performs crushing pre-treatment on the straw raw materials with abnormal toughness. The crushing pre-treatment includes flattening the straw raw materials to obtain flat straw raw materials, obtaining the change in discharge stability of the straw raw materials with abnormal toughness within a preset monitoring period before and after the crushing pre-treatment, determining whether the treatment method of the crushing pre-treatment is effective according to the change in discharge stability, and determining the crushing treatment adjustment method for the flat straw raw materials, and putting the flat straw raw materials into the crushing mechanism to obtain crushed products. Furthermore, the crushing treatment method is adaptively adjusted according to the actual toughness differences of the straw raw materials, thereby improving the stability of the feed processing crushing process and the consistency of the crushed products.

[0044] In particular, the present invention obtains the vibration characteristic parameters of the cutter during the pre-cutting process of the straw raw material. It can be understood that the straw raw material with high water content is soft and tough, and the cutter is prone to slipping when cutting along its surface, causing the cutter to deviate in the length direction of the straw raw material. The cutting trajectory determined by taking the cutter tip as the trajectory capture point can intuitively show the dynamic process of the cutter when cutting the straw and accurately quantify the vibration amplitude of the cutter. The present invention monitors the offset of the cutter during the cutting process, thereby realizing the quantification of the toughness of the straw raw material, thereby improving the stability of the feed processing and crushing process and the consistency of the crushed products.

[0045] In particular, the present invention determines whether the straw raw material has abnormal toughness through the cutter vibration characteristic parameters. It can be understood that the cutter vibration characteristic parameters can characterize the toughness of the straw raw material. For straw with normal toughness, the cutter vibration amplitude is small. When the straw toughness is abnormal, the straw has a high water content and a soft texture. The cutter is prone to slipping when cutting along its surface, and the cutter may deviate in the length direction of the straw raw material beyond the normal range. The present invention determines whether the straw raw material has abnormal toughness through the cutter vibration characteristic parameters, thereby realizing rapid identification of actual toughness differences in straw raw materials and improving the stability of the feed processing and crushing process and the consistency of the crushed products.

[0046] In particular, the present invention determines the extrusion time and extrusion pressure value for flat extrusion of straw raw materials based on the cutter vibration characteristic parameters. It can be understood that the larger the cutter vibration characteristic parameters, the greater the offset of the cutter during the cutting process, the higher the toughness of the straw raw materials, and the greater the water content, and the longer the extrusion time and the greater the extrusion pressure value are required. The present invention determines the extrusion time and extrusion pressure value for flat extrusion of straw raw materials based on the cutter vibration characteristic parameters, and thus realizes the adaptive adjustment of the crushing processing method according to the actual toughness difference of the straw raw materials, thereby improving the stability of the feed processing crushing process and the consistency of the crushed products.

[0047] In particular, the present invention performs crushing pretreatment on straw raw materials with abnormal toughness. It can be understood that straw raw materials with abnormal toughness will affect the feeding process in the crushing process. Flattening and extruding the straw raw materials with abnormal toughness can increase the contact area between the straw raw materials and the crushing mechanism, increase the friction between the crushing mechanism and the straw raw materials, make the straw raw materials easier to pass through the feeding device, and stabilize the feeding speed, which can prevent the feed port from being blocked, allowing the crushing process to continue smoothly, and at the same time alleviate the problem of uneven particle size of the crushed products caused by high toughness. The present invention performs crushing pretreatment on straw raw materials with abnormal toughness, and further, realizes the adaptive adjustment of the crushing process according to the actual toughness difference of the straw raw materials, thereby improving the stability of the feed processing crushing process and the consistency of the crushed products.

[0048] In particular, the present invention determines whether the crushing pretreatment is effective by the change in discharge stability of the straw raw material with abnormal toughness within a preset monitoring period before and after the crushing pretreatment. It can be understood that the variance of the straw raw material is calculated based on its discharge weight in several monitoring periods, which can characterize the discharge stability of the current treatment method. The larger the variance, the worse the stability. The discharge stability of the straw raw material before crushing pretreatment and the discharge stability of the straw raw material after crushing pretreatment are obtained, which can characterize the effectiveness of the current crushing pretreatment method on the abnormal toughness of the straw raw material. The present invention determines whether the crushing pretreatment is effective by obtaining the change in discharge stability of the straw raw material with abnormal toughness within a preset monitoring period before and after the crushing pretreatment, thereby realizing the characterization of the effectiveness of the crushing treatment adjustment method and improving the stability of the feed processing crushing process and the consistency of the crushing products.

[0049] In particular, the present invention adjusts the single feed amount of flat straw raw materials under the condition that the crushing pretreatment is ineffective. It can be understood that if the discharge stability of the high-toughness straw raw materials after crushing pretreatment is still not improved, it means that the straw raw materials at this time are still easy to stick together into blocks during feeding, blocking the feed port, affecting the stability of the crushing discharge, and then affecting the consistency of the crushed products. Reducing the single straw raw material feed amount can reduce the probability of straw raw materials accumulating at the feed port. A smaller feed amount makes the straw raw materials better dispersed when entering the crushing mechanism. The smaller the difference between the first discharge coefficient and the second discharge coefficient, the smaller the improvement degree of the current crushing pretreatment treatment method on the discharge stability, and a smaller single straw raw material feed amount is required to improve the discharge stability. The present invention adjusts the single feed amount of flat straw raw materials under the condition that the crushing pretreatment treatment method is ineffective, and then realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw materials, thereby improving the stability of the feed processing crushing process and the consistency of the crushing products.

[0058] See also Figure 1 As shown, it is a step diagram of the feed processing crushing method according to an embodiment of the present invention. The feed processing crushing method according to the present invention comprises:

[0059] Step S100, obtaining straw raw materials required for feed components;

[0060] Step S200, performing a pre-cutting process on the straw raw material, obtaining a cutter vibration characteristic parameter of the straw raw material during the pre-cutting process, and determining whether the straw raw material has abnormal toughness according to the cutter vibration characteristic parameter;

[0061] Step S300, performing crushing pretreatment on the straw raw material with abnormal toughness, wherein the crushing pretreatment includes flattening and squeezing the straw raw material to obtain a flat straw raw material;

[0062] Specifically, the present invention performs crushing pretreatment on straw raw materials with abnormal toughness. It can be understood that straw raw materials with abnormal toughness will affect the feeding process in the crushing process. Flattening and extruding the straw raw materials with abnormal toughness can increase the contact area between the straw raw materials and the crushing mechanism, increase the friction between the crushing mechanism and the straw raw materials, make the straw raw materials easier to pass through the feeding device, and stabilize the feeding speed, which can prevent the feed port from being blocked, and allow the crushing process to continue smoothly. At the same time, it alleviates the problem of uneven particle size of the crushed products caused by high toughness. The present invention performs crushing pretreatment on straw raw materials with abnormal toughness, and further, realizes the adaptive adjustment of the crushing process according to the actual toughness difference of the straw raw materials, thereby improving the stability of the feed processing crushing process and the consistency of the crushed products.

[0063] Step S400, obtaining the change in discharge stability of the straw raw material with abnormal toughness before and after crushing pretreatment;

[0064] Step S500, judging whether the crushing pre-treatment is effective according to the change of the discharge stability, and determining the crushing treatment adjustment method for the flat straw raw material, including:

[0065] Continuing to crush the flat straw raw material in the crushing pretreatment manner;

[0066] Or, adjusting the single feeding amount of the flat straw raw material;

[0067] Step S600: crushing the flat straw raw material in the crushing process adjustment manner to obtain a crushed product.

[0068] Specifically, the process of obtaining the cutter vibration characteristic parameters includes:

[0069] In the process of pre-cutting the straw raw material by the cutter, the cutting trajectory is determined by taking the tip of the cutter as the trajectory capture point;

[0070] The displacement of the cutting trajectory in the length direction of the straw raw material is determined as the cutter vibration characteristic parameter.

[0071] Specifically, the present invention obtains the vibration characteristic parameters of the cutter during the pre-cutting process of the straw raw material. It can be understood that the straw raw material with high water content is soft and tough, and the cutter is prone to slipping when cutting along its surface, causing the cutter to offset in the length direction of the straw raw material. The cutting trajectory determined by taking the cutter tip as the trajectory capture point can intuitively show the dynamic process of the cutter when cutting the straw and accurately quantify the vibration amplitude of the cutter. The present invention monitors the offset of the cutter during the cutting process, thereby realizing the quantification of the toughness of the straw raw material, thereby improving the stability of the feed processing and crushing process and the consistency of the crushing products.

[0072] Specifically, see Figure 2 As shown, it is a logic flow chart of determining whether the straw raw material has abnormal toughness according to an embodiment of the present invention. Determining whether the straw raw material has abnormal toughness includes:

[0073] If the cutter vibration characteristic parameter of the straw raw material does not meet the normal conditions of straw toughness, it is determined that the straw raw material has abnormal toughness;

[0074] If the cutter vibration characteristic parameters of the straw raw material meet the normal straw toughness conditions, it is determined that the straw raw material does not have abnormal toughness;

[0075] The normal condition for straw toughness is that the cutter vibration characteristic parameter of the straw raw material does not exceed a preset cutter vibration characteristic reference value.

[0076] Specifically, the cutter vibration characteristic parameter can be set by those skilled in the art according to the detection accuracy requirement of the cutter vibration characteristic. The higher the detection accuracy requirement, the smaller the cutter vibration characteristic parameter. Preferably, the cutter vibration characteristic parameter can be 1 cm.

[0077] Specifically, the present invention determines whether the straw raw material has abnormal toughness through the cutter vibration characteristic parameters. It can be understood that the cutter vibration characteristic parameters can characterize the toughness of the straw raw material. For straw with normal toughness, the cutter vibration amplitude is small. When the straw toughness is abnormal, the straw has a high water content and a soft texture. The cutter is prone to slipping when cutting along its surface, and the cutter may deviate in the length direction of the straw raw material beyond the normal range. The present invention determines whether the straw raw material has abnormal toughness through the cutter vibration characteristic parameters, thereby realizing the rapid identification of the actual toughness differences of the straw raw material, and improving the stability of the feed processing and crushing process and the consistency of the crushed products.

[0078] Specifically, the extrusion time and the extrusion pressure value for flat extrusion of the straw raw material are determined according to the cutter vibration characteristic parameters, the extrusion time is positively correlated with the cutter vibration characteristic parameters, and the extrusion pressure value is positively correlated with the cutter vibration characteristic parameters.

[0079] Specifically, the present invention determines the extrusion time and extrusion pressure value for flat extrusion of straw raw materials based on the cutter vibration characteristic parameters. It can be understood that the larger the cutter vibration characteristic parameters, the greater the offset of the cutter during the cutting process, the higher the toughness of the straw raw material, and the greater the water content, and the longer the extrusion time and the greater the extrusion pressure value are required. The present invention determines the extrusion time and extrusion pressure value for flat extrusion of straw raw materials based on the cutter vibration characteristic parameters, and thus realizes the adaptive adjustment of the crushing processing method according to the actual toughness difference of the straw raw material, thereby improving the stability of the feed processing crushing process and the consistency of the crushing product.

[0080] Specifically, the change in discharge stability is determined based on a first discharge coefficient and a second discharge coefficient of the straw raw material with abnormal toughness before and after crushing pretreatment.

[0081] Specifically, the process of determining the first discharge coefficient includes:

[0082] Obtaining the material output weight of the straw raw material during several preset monitoring cycles before the straw raw material is crushed and pre-processed;

[0083] The variance of the material output weight within the plurality of preset monitoring periods is determined as the first discharge coefficient.

[0084] Specifically, the preset monitoring period can be set by those skilled in the art according to the consistency requirements of the crushed products. The higher the consistency requirements of the crushed products, the longer the monitoring period. Preferably, the monitoring period can be 30s, and 5 monitoring periods can be set.

[0085] Here is a specific calculation process of the first discharge coefficient. The material output weight of the straw raw material in each monitoring period before crushing pretreatment is X1=38, X2=40, X3=41.5, X4=37, X5=42.3, and the average material output weight is Xv=39.76. The first discharge coefficient is

[0086] Specifically, the process of determining the second discharge coefficient includes:

[0087] Obtaining the material output weight of the straw raw material after crushing pretreatment for several preset monitoring cycles;

[0088] The variance of the material output weight within the plurality of preset monitoring periods is determined as the second discharge coefficient.

[0089] Here is a specific calculation process of the second discharge coefficient. After the straw raw material is crushed and pre-treated, the material output weight in each monitoring period is X1=50, X2=50.2, X3=50.1, X4=48, X5=49.8, and the average material output weight is Xv=49.62. The first discharge coefficient is

[0090] Specifically, see Figure 3 As shown, it is a logic flow chart of determining whether the crushing pre-processing is effective according to an embodiment of the present invention. Determining whether the crushing pre-processing is effective includes:

[0091] If the change in the discharge stability of the straw raw material with abnormal toughness meets the effect judgment condition, it is determined that the crushing pretreatment is effective;

[0092] If the change in the discharge stability of the straw raw material with abnormal toughness does not meet the effect judgment condition, it is determined that the crushing pretreatment is invalid;

[0093] The effect judgment condition is that the difference between the first discharge coefficient and the second discharge coefficient exceeds a preset difference threshold.

[0094] Specifically, the preset difference threshold can be set by those skilled in the art according to the stability requirements of the feed processing and crushing process. The higher the stability requirement, the larger the difference threshold. Preferably, the difference threshold can be 2.

[0095] Specifically, the present invention determines whether the crushing pretreatment is effective by the change in discharge stability of the straw raw material with abnormal toughness within a preset monitoring period before and after the crushing pretreatment. It can be understood that the variance of the straw raw material is calculated based on its discharge weight in several monitoring periods, which can characterize the discharge stability of the current treatment method. The larger the variance, the worse the stability. The discharge stability of the straw raw material before crushing pretreatment and the discharge stability of the straw raw material after crushing pretreatment are obtained, which can characterize the effectiveness of the current crushing pretreatment method on the abnormal toughness of the straw raw material. The present invention determines whether the crushing pretreatment is effective by obtaining the change in discharge stability of the straw raw material with abnormal toughness within a preset monitoring period before and after the crushing pretreatment, thereby realizing the characterization of the effectiveness of the crushing treatment adjustment method and improving the stability of the feed processing crushing process and the consistency of the crushing products.

[0096] Specifically, the adjustment method for crushing the flat straw raw material includes:

[0097] If the crushing pretreatment is effective, continue crushing the flat straw raw material in the manner of the crushing pretreatment;

[0098] If the crushing pretreatment is ineffective, the single feeding amount of the flat straw raw material is adjusted, and the single feeding amount is positively correlated with the difference between the first discharge coefficient and the second discharge coefficient.

[0099] Specifically, the present invention adjusts the single feed amount of flat straw raw materials under the condition that the crushing pretreatment is ineffective. It can be understood that if the discharge stability of the high-toughness straw raw materials after crushing pretreatment is still not improved, it means that the straw raw materials at this time are still easy to stick together into blocks during feeding, blocking the feed port, affecting the stability of the crushing discharge, and then affecting the consistency of the crushed products. Reducing the single straw raw material feed amount can reduce the probability of straw raw materials accumulating at the feed port. A smaller feed amount makes the straw raw materials better dispersed when entering the crushing mechanism. The smaller the difference between the first discharge coefficient and the second discharge coefficient, the smaller the degree of improvement of the current crushing pretreatment treatment method on the discharge stability, and a smaller single straw raw material feed amount is required to improve the discharge stability. The present invention adjusts the single feed amount of flat straw raw materials under the condition that the crushing pretreatment treatment method is ineffective, thereby realizing the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw materials, thereby improving the stability of the feed processing crushing process and the consistency of the crushing products.

[0100] Specifically, see Figure 4 As shown in FIG, which is a functional block diagram of a crushing system for feed processing according to an embodiment of the present invention, the present invention further provides a crushing system for feed processing, comprising:

[0101] A pre-cutting module includes a cutting unit for pre-cutting the straw raw material, and a characteristic analysis unit for obtaining the cutter vibration characteristic parameters and determining whether the straw raw material has abnormal toughness;

Preferably, it can be a plate-type extrusion mechanism for flattening the straw raw material to obtain a flat straw raw material. The plate-type extrusion mechanism is widely used in the field of food processing and will not be described in detail here.
