Description

Technical Field

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

[0002] The continuous progress of mechanical engineering technology provides 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 is widely used in feed production. Automation technology enables each parameter of feed raw materials to be accurately controlled according to the actual situation during the processing. As a common and important raw material in feed, straws have significant differences in physical properties with different water contents. This difference will cause the straw raw materials to block the feeding port during crushing, affecting the stability of the feed processing and crushing process. Therefore, improving the stability of the feed processing and crushing process and the consistency of the crushing products is a technical problem to be solved urgently.

[0003] For example, the Chinese patent application publication number: CN114917994A. This invention discloses a feed processing device and processing method, including a box body. The upper end surface of the box body is fixedly connected with a feeding frame in an embedded manner, and the bottom end surface of the box body is fixedly connected with a discharge plate in an embedded manner. A crushing roller is horizontally rotatably connected to a position near the upper part of the inner surface of the box body, and the left end of the rotating shaft of the crushing roller penetrates through the box body and is fixedly connected with a second circular gear. A first motor is fixedly connected to a position near the left side of the feeding frame on the upper end surface of the box body. It can realize the adjustment of the size of the filter holes of the filter screen, enabling the device to screen out materials with different crushing particle sizes according to different animal species, and can also drive the filtering mechanism to continuously jolt up and down while filtering, greatly improving the filtering efficiency and reducing the probability of filter screen blockage. At the same time, it can automatically perform repeated crushing processing on larger materials, ensuring the crushing effect on the materials.

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

[0005] The prior art does not consider the influence of the toughness difference of straw raw materials on the feeding stability of straw raw materials input into the crushing mechanism during the continuous production process of a large amount of feed. The prior art cannot adaptively adjust the crushing treatment method according to the actual toughness difference of straw raw materials, affecting the stability of the feed processing and crushing process and the consistency of the crushing products. Summary of the Invention

[0006] Therefore, the present invention provides a crushing method and system for feed processing to overcome the problem that the prior art cannot adaptively adjust the crushing treatment method according to the actual toughness difference of straw raw materials, affecting the stability of the feed processing and crushing process and the consistency of the crushing products.

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

[0008] Obtain the straw raw material required for the feed components;

[0014] Or, adjust the single feed amount of the flat straw raw material;

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

[0019] Further, determining whether there is an abnormal toughness phenomenon of the straw raw material includes,

[0020] If the cutter vibration characteristic parameters of the straw raw material do not meet the normal straw toughness condition, it is determined that the straw raw material has an abnormal toughness phenomenon;

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

[0022] The normal straw toughness condition is that the cutter vibration characteristic parameters of the straw raw material do not exceed the preset cutter vibration characteristic reference value.

[0023] Further, the extrusion duration and extrusion pressure value for flat extrusion of the straw raw material are determined according to the cutter vibration characteristic parameters. The extrusion duration has a positive correlation with the cutter vibration characteristic parameters, and the extrusion pressure value has a positive correlation with the cutter vibration characteristic parameters.

[0024] Further, the change in the discharge stability is determined according to the first discharge coefficient and the second discharge coefficient of the straw raw material with abnormal toughness before and after the crushing pretreatment.

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

[0026] obtaining the material output weights of several preset monitoring periods before the crushing pretreatment of the straw raw material;

[0027] determining the variance of the material output weights within the several preset monitoring periods as the first discharge coefficient.

[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] Further, determining the adjustment method for the crushing treatment of the flat straw raw material includes

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

[0037] If the crushing pretreatment is ineffective, adjust the single feed amount of the flat straw raw material. The single feed amount has a positive correlation 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, which includes a cutting unit for pre-cutting straw raw materials, and a feature analysis unit for obtaining the vibration characteristic parameters of the cutting tool and determining whether there is an abnormal toughness phenomenon in the straw raw materials;

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

[0041] A crushing module, which is connected to the crushing pretreatment module, and includes a control unit and a crushing mechanism. The control unit is used to determine whether the crushing pretreatment is effective and determine the adjustment method for the crushing treatment of flat straw raw materials;

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

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention obtains the straw raw materials required for feed components, pre-cuts the straw raw materials, obtains the vibration characteristic parameters of the cutting tool during the pre-cutting process of the straw raw materials, determines whether there is an abnormal toughness phenomenon in the straw raw materials according to the vibration characteristic parameters of the cutting tool, and performs crushing pretreatment on the straw raw materials with abnormal toughness. The crushing pretreatment includes flat extrusion of the straw raw materials to obtain flat straw raw materials, obtains the change in the discharge stability of the straw raw materials with abnormal toughness during a preset monitoring period before and after the crushing pretreatment, determines whether the treatment method of the crushing pretreatment is effective according to the change in the discharge stability, and determines the adjustment method for the crushing treatment of the flat straw raw materials. The flat straw raw materials are put into the crushing mechanism to obtain crushed products. Furthermore, it realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw materials, and improves the stability of the feed processing and crushing process and the consistency of the crushed products.

[0044] In particular, the present invention obtains the vibration characteristic parameters of the cutting tool during the pre-cutting process of the straw raw materials. It can be understood that the high-moisture straw raw materials are soft in texture and large in toughness, and it is easy for the cutting tool to slip when cutting along its surface, resulting in the cutting tool shifting in the length direction of the straw raw materials. The cutting trajectory determined with the tip of the cutting tool as the trajectory capture point can intuitively display the dynamic process of the cutting tool when cutting the straw, and accurately quantify the vibration amplitude of the cutting tool. The present invention monitors the offset amount of the cutting tool during the cutting process, and further realizes the quantification of the toughness of the straw raw materials, and improves the stability of the feed processing and crushing process and the consistency of the crushed products.

[0045] In particular, the present invention determines whether there is an abnormal toughness phenomenon in the straw raw material through the cutting tool vibration characteristic parameters. It can be understood that the cutting tool vibration characteristic parameters can characterize the toughness of the straw raw material. For straw with normal toughness, the vibration amplitude of the cutting tool is small. When the toughness of the straw is abnormal, the water content of the straw is high, the texture is soft, and the cutting tool is prone to slipping when cutting along its surface. The offset of the cutting tool in the length direction of the straw raw material may exceed the normal range. The present invention determines whether there is an abnormal toughness phenomenon in the straw raw material through the cutting tool vibration characteristic parameters. Furthermore, it realizes the rapid identification of the actual toughness difference of the straw raw material, and improves the stability of the feed processing and crushing process and the consistency of the crushed product.

[0046] In particular, the extrusion duration and extrusion pressure value for flat extrusion of the straw raw material in the present invention are determined according to the cutting tool vibration characteristic parameters. It can be understood that the larger the cutting tool vibration characteristic parameters, the larger the offset amount of the cutting tool during the cutting process, the higher the toughness of the straw raw material, the greater the water content, and the longer the extrusion duration and the larger the extrusion pressure value are required. The present invention determines the extrusion duration and extrusion pressure value for flat extrusion of the straw raw material according to the cutting tool vibration characteristic parameters. Furthermore, it realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw material, and improves the stability of the feed processing and crushing process and the consistency of the crushed product.

[0047] In particular, the present invention performs crushing pretreatment on the straw raw material with abnormal toughness phenomenon. It can be understood that the straw raw material with abnormal toughness will affect the feeding process in the crushing treatment. Performing flat extrusion treatment on the straw raw material with abnormal toughness can increase the contact area between the straw raw material and the crushing mechanism, increase the friction force between the crushing mechanism and the straw raw material, make the straw raw material easier to pass through the feeding device, and the feeding speed is stable, which can prevent the feeding port from being blocked, keep the crushing process continuous and smooth, and at the same time alleviate the problem of uneven particle size of the crushed product caused by high toughness. The present invention performs crushing pretreatment on the straw raw material with abnormal toughness phenomenon. Furthermore, it realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw material, and improves the stability of the feed processing and crushing process and the consistency of the crushed product.

[0048] In particular, the present invention determines the effectiveness of the crushing pretreatment based on the change in the discharge stability of the straw raw material with abnormal toughness during the preset monitoring periods before and after the crushing pretreatment. It can be understood that calculating the variance of the discharge weight of the straw raw material over several monitoring periods can characterize the discharge stability of the current treatment method. The larger the variance, the worse the stability. Obtaining the discharge stability of the straw raw material without crushing pretreatment and the discharge stability of the straw raw material after crushing pretreatment can characterize the effectiveness of the current crushing pretreatment method on the toughness abnormality of the straw raw material. The present invention obtains the change in the discharge stability of the straw raw material with abnormal toughness during the preset monitoring periods before and after the crushing pretreatment to determine the effectiveness of the crushing pretreatment. Furthermore, it realizes the characterization of the effectiveness of the crushing treatment adjustment method, improving the stability of the feed processing crushing process and the consistency of the crushed products.

[0049] In particular, under the condition that the crushing pretreatment is ineffective, the present invention adjusts the single feed amount of the flat straw raw material. It can be understood that for the high-toughness straw raw material after crushing pretreatment, if the discharge stability still cannot be improved, it indicates that the straw raw material is still prone to sticking together and blocking the feed inlet during feeding at this time, affecting the discharge stability of the crushing treatment and further affecting the consistency of the crushed products. Reducing the single feed amount of the straw raw material can reduce the probability of the straw raw material accumulating at the feed inlet. A smaller feed amount makes the straw raw material more 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 method on the discharge stability, and a smaller single feed amount of the straw raw material is required to improve the discharge stability. The present invention adjusts the single feed amount of the flat straw raw material under the condition that the crushing pretreatment method is ineffective. Furthermore, it realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw material, improving the stability of the feed processing crushing process and the consistency of the crushed products.

[0058] Please refer to Figure 1 as shown, which is a step diagram of the crushing method for feed processing in an embodiment of the present invention. The crushing method for feed processing of the present invention includes:

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

[0060] Step S200, performing pre-cutting treatment on the straw raw material, obtaining the cutter vibration characteristic parameters of the straw raw material during the pre-cutting treatment, and determining whether there is an abnormal toughness phenomenon of the straw raw material according to the cutter vibration characteristic parameters;

[0061] Step S300, performing crushing pretreatment on the straw raw material with abnormal toughness phenomenon. The crushing pretreatment includes flat extrusion of the straw raw material to obtain flat straw raw material;

[0062] Specifically, in the present invention, by performing crushing pretreatment on straw raw materials with abnormal toughness, it can be understood that the straw raw materials with abnormal toughness will affect the feeding process during crushing treatment. By performing flat extrusion treatment on the straw raw materials with abnormal toughness, the contact area between the straw raw materials and the crushing mechanism can be increased, the friction force between the crushing mechanism and the straw raw materials can be increased, making the straw raw materials more likely to pass through the feeding device, with a stable feeding speed, preventing blockage of the feeding port, enabling the crushing process to continue smoothly, and at the same time alleviating the problem of uneven particle size of the crushing products caused by high toughness. By performing crushing pretreatment on the straw raw materials with abnormal toughness, furthermore, the present invention realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw materials, improving the stability of the feed processing crushing process and the consistency of the crushing products.

[0063] Step S400: Obtain the change in the discharge stability of the straw raw materials with abnormal toughness before and after crushing pretreatment.

[0064] Step S500: Determine whether the crushing pretreatment is effective according to the change in the discharge stability, and determine the adjustment method for the crushing treatment of the flat straw raw materials, including

[0065] Continuing to crush the flat straw raw materials in the way of the crushing pretreatment;

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

[0067] Step S600: Crush the flat straw raw materials in the crushing treatment adjustment method to obtain crushing products.

[0068] Specifically, the process of obtaining the cutting tool vibration characteristic parameters includes

[0069] During the pre-cutting treatment of the straw raw materials by the cutting tool, determining the cutting trajectory with the tip of the cutting tool as the trajectory capture point;

[0070] Determining the displacement amount of the cutting trajectory in the length direction of the straw raw materials as the cutting tool vibration characteristic parameter.

[0071] Specifically, the present invention obtains the cutting tool vibration characteristic parameters of the straw raw materials during the pre-cutting treatment. It can be understood that the straw raw materials with high water content are soft and have high toughness, and the cutting tool is prone to slipping when cutting along its surface, resulting in the cutting tool shifting in the length direction of the straw raw materials. The cutting trajectory determined with the tip of the cutting tool as the trajectory capture point can intuitively display the dynamic process of the cutting tool when cutting the straw, accurately quantifying the vibration amplitude of the cutting tool. By monitoring the offset amount of the cutting tool during the cutting process, furthermore, the present invention realizes the quantification of the toughness of the straw raw materials, improving the stability of the feed processing crushing process and the consistency of the crushing products.

[0072] Specifically, please refer to Figure 2 As shown, it is a logic flowchart for determining whether there is an abnormal toughness phenomenon in the straw raw material in an embodiment of the present invention. Determining whether there is an abnormal toughness phenomenon in the straw raw material includes

[0073] If the cutter vibration characteristic parameter of the straw raw material does not meet the normal straw toughness condition, it is determined that there is an abnormal toughness phenomenon in the straw raw material;

[0074] If the cutter vibration characteristic parameter of the straw raw material meets the normal straw toughness condition, it is determined that there is no abnormal toughness phenomenon in the straw raw material;

[0075] The normal straw toughness condition 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 requirements of the cutter vibration characteristics. The higher the detection accuracy requirements, the smaller the cutter vibration characteristic parameter. Preferably, the cutter vibration characteristic parameter can be 1 cm.

[0077] Specifically, the present invention determines whether there is an abnormal toughness phenomenon in the straw raw material through the cutter vibration characteristic parameter. It can be understood that the cutter vibration characteristic parameter 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 water content of the straw is high, the texture is soft, and it is easy to slip when the cutter cuts along its surface. The cutter may deviate beyond the normal range in the length direction of the straw raw material. The present invention determines whether there is an abnormal toughness phenomenon in the straw raw material through the cutter vibration characteristic parameter, and further realizes the rapid identification of the actual toughness difference of the straw raw material, improving the stability of the feed processing and crushing process and the consistency of the crushed product.

[0078] Specifically, the extrusion duration and extrusion pressure value for flat extrusion of the straw raw material are determined according to the cutter vibration characteristic parameter. The extrusion duration has a positive correlation with the cutter vibration characteristic parameter, and the extrusion pressure value has a positive correlation with the cutter vibration characteristic parameter.

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

[0080] Specifically, the change situation of the discharge stability is determined according to the first discharge coefficient and the second discharge coefficient of the straw raw material with abnormal toughness before and after the crushing pretreatment.

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

[0082] Obtaining the material output weights of several preset monitoring periods before the straw raw material undergoes the crushing pretreatment;

[0083] Determining the variance of the material output weights within the several preset monitoring periods as the first discharge coefficient.

[0084] Specifically, the preset monitoring period can be set by those skilled in the art according to the consistency requirement of the crushing product. The higher the consistency requirement of the crushing product, 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 for the first discharge coefficient. The material output weights of each monitoring period before the straw raw material undergoes the crushing pretreatment are X1 = 38, X2 = 40, X3 = 41.5, X4 = 37, X5 = 42.3 respectively, the average value of the material output weight is Xv = 39.76, and the first discharge coefficient is

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

[0087] Obtaining the material output weights of several preset monitoring periods after the straw raw material undergoes the crushing pretreatment;

[0088] Determining the variance of the material output weights within the several preset monitoring periods as the second discharge coefficient.

[0089] A specific calculation process of the second discharge coefficient is given here. The material output weights of the straw raw materials in each monitoring period after crushing pretreatment are X1 = 50, X2 = 50.2, X3 = 50.1, X4 = 48, X5 = 49.8 respectively, and the average material output weight is Xv = 49.62. The first discharge coefficient is

[0090] Specifically, please refer to Figure 3 As shown, it is a logic flowchart for determining whether the crushing pretreatment is effective in an embodiment of the present invention. Determining whether the crushing pretreatment is effective includes

[0091] If the change in the discharge stability of the straw raw materials with abnormal toughness conforms to 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 materials with abnormal toughness does not conform to the effect judgment condition, it is determined that the crushing pretreatment is ineffective;

[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 the discharge stability of the straw raw materials with abnormal toughness in the preset monitoring period before and after the crushing pretreatment. It can be understood that calculating the variance based on the discharge weights of the straw raw materials in several monitoring periods can characterize the discharge stability of the current treatment method. The larger the variance, the worse the stability. Obtaining the discharge stability of the straw raw materials without crushing pretreatment and the discharge stability of the straw raw materials after crushing pretreatment can characterize the effective degree of the current crushing pretreatment method for the abnormal toughness phenomenon of the straw raw materials. The present invention determines whether the crushing pretreatment is effective by obtaining the change in the discharge stability of the straw raw materials with abnormal toughness in the preset monitoring period before and after the crushing pretreatment. Furthermore, it realizes the characterization of the effectiveness of the crushing treatment adjustment method, and improves the stability of the feed processing and crushing process and the consistency of the crushing products.

[0096] Specifically, determining the crushing treatment adjustment method for the flat straw raw materials includes

[0097] If the crushing pretreatment is effective, continue to crush the flat straw raw materials in the way of the crushing pretreatment;

[0098] If the crushing pre-treatment is ineffective, adjust the single-feed amount of the flat straw raw material, and the single-feed amount is positively correlated with the difference between the first discharge coefficient and the second discharge coefficient.

[0099] Specifically, under the condition that the crushing pre-treatment is ineffective, the present invention adjusts the single-feed amount of the flat straw raw material. It can be understood that for the high-toughness straw raw material after crushing pre-treatment, if the discharge stability still cannot be improved, it means that the straw raw material is still prone to sticking together and blocking the feed inlet during feeding at this time, affecting the discharge stability of the crushing process, and further affecting the consistency of the crushing product. Reducing the single-feed amount of the straw raw material can reduce the probability of the straw raw material accumulating at the feed inlet. A smaller feed amount makes the straw raw material more 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 pre-treatment method on the discharge stability, and a smaller single-feed amount of the straw raw material is required to improve the discharge stability. Under the condition that the treatment method of the crushing pre-treatment is ineffective, the present invention adjusts the single-feed amount of the flat straw raw material. Furthermore, it realizes the adaptive adjustment of the crushing treatment method according to the actual toughness difference of the straw raw material, improving the stability of the feed processing crushing process and the consistency of the crushing product.

[0100] Specifically, please refer to Figure 4 As shown, it is a functional block diagram of a crushing system for feed processing according to an embodiment of the present invention. The present invention also provides a crushing system for feed processing, including:

[0101] A pre-cutting module, which includes a cutting unit for pre-cutting the straw raw material and a feature analysis unit for obtaining the cutting vibration characteristic parameters of the cutting tool and determining whether there is an abnormal toughness phenomenon in the straw raw material;

[0102] Specifically, the present invention does not limit the specific structure of the cutting unit. Preferably, it can be a straight-edge blade to realize the pre-cutting treatment of the straw raw material, which will not be elaborated here.
