Description

Technical Field

[0001] The present invention relates to the technical field of feed production, in particular to a production method for cattle feed. Background Art

[0002] In modern animal husbandry, the production quality of cattle feed is directly related to the growth and development, health status and breeding efficiency of cattle. Traditional cattle feed production methods have many shortcomings in the raw material processing link. On the one hand, during the crushing process, a single crushing method is often used, and the differences in the characteristics of different raw materials are not fully considered. For example, the hardness, volume, density and other physical properties of different raw materials are different. For example, corn stalks are soft in texture but large in volume, while sorghum seeds are hard and small in volume. If they are mixed and crushed indiscriminately, some raw materials may be over-crushed and some may be under-crushed, affecting the uniformity and palatability of the feed, and thus reducing the digestion and absorption rate of the cattle to the feed. On the other hand, in the entire production process, there is a lack of precise monitoring and scientific regulation of key parameters of the production process, and it is impossible to detect and solve abnormal situations in the production process in a timely manner.

[0003] For example, Chinese patent application publication number: CN118341548A discloses a complete pellet cattle feed crushing and screening device and a method of use, which relates to the field of feed processing devices, including: a storage hopper; a storage hopper is installed on the top of the feeding shell, and a feeding wheel is installed on the top of the feeding shell, and a reduction motor is installed on the top of the feeding shell, and the rotating shaft of the reduction motor is fixedly connected to the feeding wheel; a pelletizing shell, the top of the pelletizing shell is connected to the feeding shell, and a crushing motor is installed on the bottom of the pelletizing shell, a grinding disc is installed inside the pelletizing shell, and the rotating shaft of the crushing motor is fixedly connected to the grinding disc. The present invention uses the feeding wheel to perform intermittent and uniform feeding, avoids the occurrence of material accumulation inside the pelletizing shell, ensures the normal operation of the device itself, does not require manual processing of the material accumulation problem, and reduces the difficulty of device maintenance. It solves the problem that the existing complete pellet cattle feed crushing and screening device is very likely to have material accumulation due to excessive feeding inside the device during use, affecting the production and processing efficiency of complete pellet feed.

[0004] However, the existing technology has the problem that the analysis of the crushing process of the raw materials for cattle feed preparation is not accurate enough, resulting in the inability to adjust the unqualified crushing process in time, resulting in low quality of the prepared cattle feed. Summary of the Invention

[0005] To this end, the present invention provides a method for producing cattle feed, which is used to overcome the problem in the prior art that the analysis of the crushing process of the raw materials for cattle feed preparation is not accurate enough, resulting in the inability to adjust the unqualified crushing process in time, resulting in low quality of the prepared cattle feed.

[0006] To achieve the above object, the present invention provides a method for producing cattle feed, comprising:

[0007] Obtain data on the type, weight, and historical crushing time of raw materials used in cattle feed preparation;

[0008] Determining the crushing time of a raw material combination based on the maximum crushing time of a single type of raw material in the cattle feed preparation raw material combination, and determining whether to perform batch crushing or mixed crushing of the cattle feed preparation raw material combination based on the historical crushing time range of each raw material in the cattle feed preparation raw material combination;

[0009] Obtaining the outflow rate of the crushed raw materials under the corresponding crushing treatment mode within a preset time period, and determining whether to perform mixing treatment or analyze the cause of abnormal outflow rate of the crushed raw materials based on the degree of fluctuation of the outflow rate of the crushed raw materials under the corresponding crushing treatment mode within a plurality of preset time periods;

[0010] When analyzing the cause of the abnormal outflow rate of the crushed raw material, whether the crushed raw material is blocked during the abnormal outflow rate period, or whether the actual crushing time of the crushed raw material is within the preset crushing time range, the crushing raw material blockage area is marked or the crushing process is optimized;

[0011] Based on whether the position characteristics of the raw material blockage area within the preset period are regular, it is determined to adjust the shape of the discharge port or add a diversion device;

[0012] The optimized crushing process includes replacing crushing equipment and adjusting the crushing time of the prepared raw material combination.

[0013] Furthermore, determining that the cattle feed preparation raw materials are subjected to batch crushing or mixed crushing includes:

[0014] If there is a raw material in the cattle feed preparation raw material combination whose crushing time is not within the historical crushing time range, determining to perform batch crushing processing on the cattle feed preparation raw material;

[0015] If there is no raw material in the cattle feed preparation raw material combination whose crushing time is not included in the historical crushing time range, it is determined to perform mixed crushing processing on the cattle feed preparation raw materials.

[0016] Furthermore, the reasons for abnormal outflow rate of the mixed or crushed raw materials include:

[0017] If the fluctuation degree of the outflow speed of the crushed raw materials under the corresponding crushing treatment mode within a certain preset time period is greater than the preset fluctuation degree, the cause of the abnormal outflow speed of the crushed raw materials is determined and analyzed;

[0018] If the fluctuation degree of the outflow velocity of the crushed raw materials under the corresponding crushing treatment mode within a number of preset time periods is less than or equal to the preset fluctuation degree, it is determined that the mixing treatment is to be performed.

[0019] Furthermore, identifying and marking the crushing material blockage area or optimizing the crushing process includes:

[0020] If crushing material blockage occurs during the period of abnormal crushing material outflow rate, the crushing material blockage area is identified and marked;

[0021] If no crushing material blockage occurs during the time period when the crushing material outflow rate is abnormal and the actual crushing time of the crushing material is within the preset crushing time range, determining to adjust the crushing time of the prepared raw material combination;

[0022] If there is no blockage of the crushed raw materials within the time period of abnormal outflow speed of the crushed raw materials and the actual crushing time of the crushed raw materials is not within the preset crushing time range, it is determined to replace the crushing device.

[0023] Furthermore, the preset crushing time range is determined according to the historical crushing time range of the raw material type corresponding to the maximum crushing time in the prepared raw material.

[0024] Further, determining to adjust the shape of the discharge port or add a guide device includes:

[0025] If the location characteristics of the raw material blocking area are regular within the preset period, the shape of the discharge port is adjusted;

[0026] If the position characteristics of the raw material blockage area are irregular within the preset period, it is determined to add a diversion device.

[0027] Furthermore, the adjustment amount of the crushing time for preparing the raw material combination is negatively correlated with the abnormal time of the outflow speed of the crushed raw material.

[0028] Furthermore, determining the degree of fluctuation of the outflow velocity of the crushed raw material includes:

[0029] Continuously measure the outflow rate of crushed raw materials within a preset time period;

[0030] Calculate the average outflow rate within a number of preset time periods;

[0031] Calculate the difference between the outflow rate and the average value within each preset time period;

[0032] The absolute value of the difference is calculated as a quantitative indicator of the degree of volatility.

[0033] Furthermore, determining whether the position characteristics of the raw material blocking area within the preset period are regular includes:

[0034] During a preset period, the blockage situation near the discharge port is continuously monitored through sensors or manual recording, including the time, location and frequency of blockage;

[0035] The frequency of the location of the blockage area appearing at the same location within a preset period is greater than a preset frequency, and the location characteristics of the raw material blockage area within the preset period are regular;

[0036] The frequency of the position of the blocking area appearing at the same position within the preset period is less than or equal to the preset frequency, and the position characteristics of the raw material blocking area within the preset period are irregular.

[0037] Furthermore, the preset fluctuation degree is determined based on an average value of the outflow rate of the crushed raw materials under the corresponding crushing treatment mode within a preset time period after the same cattle feed preparation raw materials are crushed for several times.

[0038] Compared with the prior art, the beneficial effect of the present invention lies in that, by comparing the historical crushing time range of each raw material in the raw material combination for cattle feed preparation with the crushing time of the raw material combination, the present invention determines a reasonable crushing method, avoids insufficient or excessive crushing of some raw materials due to mixed crushing, reduces the time of repeated crushing, and improves the overall crushing efficiency. The reasonable crushing method ensures that each raw material can achieve an appropriate degree of crushing, makes the feed more uniform during mixing, and ensures a balanced distribution of nutrients in the cattle feed. Through the above method, the accuracy of the analysis of the crushing process of the raw materials for cattle feed preparation is improved, thereby improving the quality of the prepared cattle feed.

[0039] Furthermore, the present invention can promptly detect abnormal conditions in the crushing process by accurately measuring and quantifying the degree of outflow velocity fluctuation. When the degree of fluctuation is greater than a preset value, the cause is quickly analyzed and measures are taken to avoid production interruptions due to equipment failure or raw material problems, thereby ensuring the continuity and stability of the production process. A stable outflow velocity is one of the key factors in ensuring uniform quality of cattle feed. By strictly controlling the outflow velocity fluctuation, the particle size of the crushed raw materials is uniform, which is beneficial for subsequent mixing processing, thereby ensuring uniform distribution of various nutrients in the feed and improving feed quality. Analysis of the degree of outflow velocity fluctuation helps to discover potential problems in equipment operation. For example, if it is found that the abnormal outflow velocity fluctuation is caused by wear of crusher parts or blocked conveying pipelines, timely repairs or replacements can be carried out. The above method improves the accuracy of the analysis of the crushing process of the raw materials for cattle feed preparation, thereby improving the quality of the prepared cattle feed.

[0040] Furthermore, when the present invention finds that the outflow rate of the crushed raw material is abnormal, the crushing equipment and the discharge pipe are immediately inspected, and whether there is a blockage can be quickly determined. If there is a blockage, the blocked area is marked and cleaned in time to avoid production stagnation due to blockage. When the outflow rate is abnormal and there is no blockage, and the actual crushing time is within the preset range, the crushing time of the prepared raw material combination is adjusted by adjusting the coefficient. The adjustment is negatively correlated with the abnormal outflow rate of the crushed raw material, so that the crushing time can be more in line with actual production needs and the production rhythm can be optimized. When the actual crushing time is not within the preset crushing time range, the hammer head, screen and other key crushing instruments of the crusher are replaced in time to ensure the stability and consistency of the crushing effect. The new crushing instrument can crush the raw material more effectively, make the raw material particle size uniform, which is beneficial to subsequent mixing processing, thereby ensuring the uniform distribution of nutrients in the feed and improving the quality of the feed. The above method improves the accuracy of the analysis of the crushing process of the raw materials for cattle feed preparation, thereby improving the quality of the prepared cattle feed.

[0041] Furthermore, the present invention can timely discover problems in the discharge process by monitoring and analyzing the blockage of the discharge port within a preset period, and take targeted measures. Whether it is adjusting the shape of the discharge port or adding a guide device, it can effectively reduce the blockage phenomenon and avoid production interruptions caused by blockage. It can accurately judge the cause of the blockage and take appropriate measures to avoid material waste and excessive equipment wear caused by frequent blockages. For example, after adding the guide device, the material flow is smoother, reducing the accumulation and loss of materials at the discharge port, and at the same time reducing the additional energy consumption and wear of the equipment due to handling blocked materials, thereby reducing production costs.

[0045] In order to make the objects and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with embodiments; it should be understood that the specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention.

[0046] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0047] See Figure 1-Figure 3 As shown, Figure 1 This is a workflow diagram of a method for producing cattle feed according to an embodiment of the present invention; Figure 2 This is a flowchart for determining the degree of fluctuation of the outflow rate of crushed raw materials in a method for producing cattle feed according to an embodiment of the present invention; Figure 3 The present invention is a flowchart for determining a crushing processing method in a method for producing cattle feed according to an embodiment of the present invention.

[0048] The method for producing cattle feed according to an embodiment of the present invention comprises:

[0049] Step S1, obtaining the type data, weight data and historical crushing time data of the raw materials for cattle feed preparation;

[0050] Step S2, determining the crushing time of a raw material combination based on the maximum crushing time of a single type of raw material in the cattle feed preparation raw material, and determining whether to perform batch crushing or mixed crushing of the cattle feed preparation raw material based on the historical crushing time range of each raw material in the cattle feed preparation raw material combination;

[0051] Step S3, obtaining the outflow velocity of the crushed raw materials under the corresponding crushing treatment mode within a preset time period, and determining whether to perform mixing treatment or analyze the cause of abnormal outflow velocity of the crushed raw materials based on the degree of fluctuation of the outflow velocity of the crushed raw materials under the corresponding crushing treatment mode within a plurality of preset time periods;

[0052] Step S4, when analyzing the cause of the abnormal outflow rate of the crushed material, whether the crushed material is blocked during the abnormal outflow rate period, or whether the actual crushing time of the crushed material is within the preset crushing time range, to determine the crushing material blockage area or optimize the crushing process;

[0053] Step S5, determining whether to adjust the shape of the discharge port or add a guide device based on whether the position characteristics of the raw material blocking area within the preset period are regular;

[0054] The optimized crushing process includes replacing crushing equipment and adjusting the crushing time of the prepared raw material combination.

[0055] Specifically, in step S2, when determining to perform batch crushing or mixed crushing on the raw materials for cattle feed preparation, determining whether to perform batch crushing or mixed crushing on the raw materials for cattle feed preparation is based on the historical crushing time range of each raw material in the raw material combination for cattle feed preparation;

[0056] When there is a raw material in the cattle feed preparation raw material combination whose crushing time is not within the historical crushing time range, determining to perform batch crushing processing on the cattle feed preparation raw material;

[0057] When there is no raw material whose crushing time is not included in the historical crushing time range in the cattle feed preparation raw material combination, it is determined to perform mixed crushing processing on the cattle feed preparation raw materials.

[0058] In the embodiment of the present invention, if the maximum value of the crushing time of a single type of raw material in the preparation is 10 minutes of rice husk (the maximum value of the historical crushing time range is taken), the crushing time of the raw material combination prepared this time is determined to be 10 minutes, and then it is determined whether there is a raw material whose crushing time is not included in the historical crushing time range. The historical crushing time range of corn is 4-6 minutes, which does not include 10 minutes; the historical crushing time range of soybean meal is 3-5 minutes, which does not include 10 minutes; the historical crushing time range of alfalfa is 7-9 minutes, which also does not include 10 minutes. Because there are raw materials in the cattle feed preparation raw material combination whose historical crushing time range does not include the crushing time (10 minutes), it is determined that this batch of cattle feed preparation raw materials is crushed in batches. First, the corn and soybean meal are crushed together, and the crushing time is set to 5 minutes (the middle value of the historical crushing time range of the two to ensure that both can be crushed well), and then the alfalfa and rice husk are crushed together, and the crushing time is set to 9 minutes (the middle value of the historical crushing time range of the two).

[0059] The present invention determines a reasonable crushing method by comparing the historical crushing time range of each raw material in the raw material combination for cattle feed preparation with the crushing time of the raw material combination, thereby avoiding insufficient or excessive crushing of some raw materials due to mixed crushing, reducing the time of repeated crushing, and improving the overall crushing efficiency. The reasonable crushing method ensures that each raw material can achieve an appropriate crushing degree, making the feed more uniform during mixing and ensuring a balanced distribution of nutrients in the cattle feed. Through the above method, the accuracy of the analysis of the crushing process of the raw materials for cattle feed preparation is improved, thereby improving the quality of the prepared cattle feed.

[0060] Specifically, in step S3, when it is determined to perform mixing processing or analyze the cause of the abnormal outflow rate of the crushed raw materials, the determination of performing mixing processing or analyzing the cause of the abnormal outflow rate of the crushed raw materials is made based on the degree of fluctuation of the outflow rate of the crushed raw materials under the corresponding crushing processing mode within a plurality of preset time periods;

[0061] When the fluctuation degree of the outflow speed of the crushed raw materials under the corresponding crushing treatment mode within a certain preset time period is greater than the preset fluctuation degree, determining and analyzing the cause of the abnormal outflow speed of the crushed raw materials;

[0062] When the fluctuation degree of the outflow velocity of the crushed raw materials under the corresponding crushing treatment mode within a number of preset time periods is less than or equal to the preset fluctuation degree, it is determined to perform the mixing treatment.

[0063] In the embodiment of the present invention, the preset fluctuation degree is the average value of the outflow rate of the crushed raw material under the corresponding crushing treatment mode within a preset time after several crushing of the same cattle feed preparation raw material. The preset time is set to 2 minutes, but the above value is not limited to this. Those skilled in the art can also adjust the value according to actual needs.

[0064] Specifically, in step S3, the step of determining the degree of fluctuation of the outflow velocity of the crushed raw material includes:

[0065] Step S3301, continuously measuring the outflow rate of the crushed raw material within a preset time period;

[0066] Step S3302, calculating the average value of the outflow speed within a plurality of preset time periods;

[0067] Step S3303, calculating the difference between the outflow rate and the average value in each preset time period;

[0068] Step S3304: Calculate the absolute value of the difference as a quantitative indicator of the degree of fluctuation.

[0069] The present invention can timely discover abnormal conditions in the crushing process by accurately measuring and quantifying the degree of fluctuation of the outflow velocity. When the degree of fluctuation is greater than a preset value, the cause is quickly analyzed and measures are taken to avoid production interruptions due to equipment failure or raw material problems, thereby ensuring the continuity and stability of the production process. A stable outflow velocity is one of the key factors to ensure uniform quality of cattle feed. By strictly controlling the outflow velocity fluctuation, the particle size of the crushed raw materials is uniform, which is conducive to subsequent mixing processing, thereby ensuring uniform distribution of various nutrients in the feed and improving the quality of the feed. Analysis of the degree of outflow velocity fluctuation helps to discover potential problems in equipment operation. For example, if it is found that the abnormal outflow velocity fluctuation is caused by wear of crusher parts or blocked conveying pipelines, timely repairs or replacements can be carried out. The above method improves the accuracy of the analysis of the crushing process of the raw materials for cattle feed preparation, thereby improving the quality of the prepared cattle feed.

[0070] Specifically, in step S4, when determining to mark a crushing material blockage area or to optimize the crushing process, the marking of the crushing material blockage area or the optimization of the crushing process is determined based on whether crushing material blockage occurs within the time period of abnormal crushing material outflow speed, or whether the actual crushing time of the crushing material is within the preset crushing time range;

[0071] When crushing material blockage occurs during the period of abnormal outflow rate of crushing material, the crushing material blockage area is determined and marked;

[0072] When no crushing material blockage occurs during the time period when the outflow rate of the crushed raw materials is abnormal and the actual crushing time of the crushed raw materials is within the preset crushing time range, determining to adjust the crushing time of the prepared raw material combination;

[0073] When no crushing material blockage occurs within the time period of abnormal crushing material outflow speed and the actual crushing time of the crushed material is not within the preset crushing time range, it is determined to replace the crushing device.

[0074] The preset crushing time range in the embodiment of the present invention is the historical crushing time range of the raw material type corresponding to the maximum crushing time in the preparation of raw materials, but the above value is not limited to this. Those skilled in the art can also adjust the value according to actual needs.

[0075] In the embodiment of the present invention, when determining to mark the crushing raw material blockage area or optimizing the crushing process, the crushing equipment and the discharge pipe are inspected to see whether there is any crushing raw material blockage. If there is a blockage, the crushing raw material blockage area is marked. If there is no crushing raw material blockage within the time period of abnormal crushing raw material outflow speed and the actual crushing time of the crushing raw material is not within the preset crushing time range, it is determined to replace the crushing equipment, including but not limited to replacing the key crushing equipment such as the hammer head and screen of the crusher.

[0076] Specifically, in step S5, when it is determined to adjust the crushing time of the raw material combination, it is determined to adjust the crushing time of the raw material combination by an adjustment coefficient.

[0077] In the embodiment of the present invention, the value range of the adjustment coefficient is set to 0.82-0.96, and the value of the adjustment coefficient is preferably 0.89. The adjustment amount of the crushing time for preparing the raw material combination is negatively correlated with the abnormal duration of the crushed raw material outflow rate, but the above value is not limited to this. Those skilled in the art can also adjust the value according to actual needs.

[0078] When the present invention finds that the outflow speed of the crushed raw material is abnormal, the crushing equipment and the discharge pipe are immediately checked, and it can quickly determine whether there is a blockage. If there is a blockage, the blocked area is marked and cleaned in time to avoid production stagnation due to the blockage. When the outflow speed is abnormal and there is no blockage, and the actual crushing time is within the preset range, the crushing time of the prepared raw material combination is adjusted by adjusting the coefficient. The adjustment is negatively correlated with the abnormal outflow speed of the crushed raw material, so that the crushing time can be more in line with actual production needs and the production rhythm is optimized. When the actual crushing time is not within the preset crushing time range, the hammer head, screen and other key crushing instruments of the crusher are replaced in time to ensure the stability and consistency of the crushing effect. The new crushing instrument can crush the raw material more effectively, make the raw material particle size uniform, which is beneficial to subsequent mixing processing, thereby ensuring the uniform distribution of nutrients in the feed and improving the quality of the feed. The above method improves the accuracy of the analysis of the crushing process of the raw materials for cattle feed preparation, thereby improving the quality of the prepared cattle feed.

[0079] Specifically, in step S5, when it is determined to adjust the shape of the discharge port or add a guide device, the adjustment of the shape of the discharge port or the addition of the guide device is determined based on whether the position characteristics of the raw material blocking area within the preset period are regular;

[0080] When the position characteristics of the raw material blocking area are regular within the preset period, the shape of the discharge port is adjusted;

[0081] When the position characteristics of the raw material blockage area within the preset period are irregular, it is determined to add a diversion device.

[0082] In the embodiment of the present invention, the preset period is set to the duration of 8 raw material blockages, but the above value is not limited thereto, and those skilled in the art can also adjust the value according to actual needs.

[0083] Specifically, in step S5, the step of determining whether the position characteristics of the raw material blocking area within the preset period are regular includes:

[0084] Step S5501: within a preset period, continuously monitor the blockage situation near the discharge port by means of sensors or manual recording, including the time, location, and frequency of blockage;

[0085] Step S5502: The frequency of the location of the blocked area appearing at the same location within a preset period is greater than a preset frequency, and the location characteristics of the raw material blocked area within the preset period are regular;

[0086] Step S5503: The frequency of the location of the blocked area appearing at the same location within a preset period is less than or equal to a preset frequency, and the location characteristics of the raw material blocked area within the preset period are irregular.

[0087] In the embodiment of the present invention, the value range of the preset frequency is set to 0.7-0.9, and the value of the preset frequency is preferably 0.75, but the above value is not limited thereto. Those skilled in the art can also adjust the value according to actual needs.

[0088] In the embodiment of the present invention, during the production process, when the raw material is blocked for the eighth time, the eight blockages are summarized and analyzed, and the location of each blockage is recorded in detail through a sensor installed near the discharge port. Statistics show that six of the eight blockages occurred at the left edge of the discharge port. A judgment standard is set. If the frequency of blockage at the same position within a preset period reaches 75% or above, it is considered that the position characteristic of the raw material blockage area within the preset period is regular. Here, 6÷8=75%, which meets the judgment standard. Therefore, the position characteristic of the raw material blockage area within the preset period is judged. Due to the position characteristic of the raw material blockage area within the preset period, it is determined to adjust the shape of the discharge port. Based on the principles of fluid mechanics and past experience, the technicians adjusted the discharge port from the original circle to a square. The purpose is to change the flow state of the material at the discharge port, so that the material can flow out more evenly and reduce the accumulation and blockage at the left edge.

[0089] The present invention monitors and analyzes the blockage of the discharge port within a preset period, can timely discover problems in the discharge link, and take targeted measures. Whether it is adjusting the shape of the discharge port or adding a guide device, it can effectively reduce the blockage phenomenon, avoid production interruptions caused by blockage, accurately judge the cause of the blockage and take appropriate measures, avoid material waste and excessive equipment wear caused by frequent blockages. For example, after adding the guide device, the material flow is smoother, reducing the accumulation and loss of materials at the discharge port, and at the same time reducing the additional energy consumption and wear of the equipment caused by handling blocked materials, thereby reducing production costs.

[0090] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
