Description

Technical Field

[0001] The present invention relates to the technical field of feed preparation, and particularly relates to an intelligent control system and device for a feed preparation device. Background Art

[0002] Straw feed mainly refers to fibrous feed made by crushing straws such as sweet sorghum, corn, reed, and cotton. It is the main feed for ruminants. Crop straws have a high crude fiber content, are difficult to be digested and absorbed by animals, have few available nutrients, and poor palatability. They are classified as roughage in feed taxonomy. Cellulose, hemicellulose, and lignin are tightly combined and intertwined to form crude fiber, which is the main component of plant cell walls. These natural organic macromolecules have a very firm structure, can only absorb water and swell, cannot be decomposed by the digestive juices and enzymes of monogastric animals, and can only be slightly fermented by the microbes in their cecum, with a very low digestibility, and are only suitable for feeding ruminant livestock.

[0003] When preparing straw feed, it is necessary to cut the straw into smaller particles for ruminants to ingest. The main components of the feed preparation device are a driving motor and a cutting device, and the cutting device is driven by the driving motor to rotate to cut the straw.

[0004] The existing technology has the following deficiencies: When preparing straw feed in the existing technology, in order to improve the preparation efficiency of straw feed, usually the rotation speed of the cutting device is increased. When the rotation speed of the cutting device increases, the driving motor will be in a high-load operation state. Since the operating state of the driving motor cannot be known, when the operating state of the driving motor is abnormal, it cannot be discovered in time, which will cause the driving motor to be in an abnormal operating state for a long time, accelerate the damage rate of the driving motor, and thus greatly reduce the service life of the driving motor.

[0005] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure, and therefore it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent control system and device for a feed preparation device. By providing cutting support points with the first movable baffle and the second movable baffle, the cutting efficiency of straw is greatly improved. By reducing the passing rate of straw through the gap, the cutting efficiency of straw can be further improved. By analyzing the operating state of the driving motor, it can be discovered in time when the driving motor is in an abnormal operating state, and the abnormal operating state of the driving motor can be adjusted, effectively preventing the driving motor from being in an abnormal operating state for a long time and accelerating the damage rate of the driving motor, and extending the service life of the driving motor, so as to solve the problems in the above background art.

[0007] To achieve the above object, the present invention provides the following technical solution: An intelligent device for a feed preparation device, comprising a shredding tank, a driving motor, and cutting knives annularly arrayed outside the output shaft of the driving motor. The cutting knives are evenly distributed from top to bottom. An installation frame is provided at the top of the shredding tank, and the driving motor is installed on the installation frame. First movable baffles annularly arrayed and second movable baffles annularly arrayed are respectively provided at the top and bottom of the cutting knives. A gap is formed between the first movable baffle and the second movable baffle, and the cutting knives are respectively arranged in the corresponding gaps. An adjusting mechanism for adjusting the size of the gap between the first movable baffle and the second movable baffle is provided between the first movable baffle and the second movable baffle.

[0008] Preferably, the adjusting mechanism includes a fixed frame connected in the shredding tank, an adjusting motor installed on the top of the installation frame, and a threaded rod connected to the end of the output shaft of the adjusting motor. The threaded rod penetrates through the first movable baffle and the second movable baffle at the corresponding positions.

[0009] Preferably, the thread directions at the corresponding positions of the first movable baffle are opposite to those at the corresponding positions of the second movable baffle. When the adjusting motor operates, it drives the first movable baffle and the second movable baffle to approach the cutting knives between them simultaneously or to move away from the cutting knives between them simultaneously.

[0010] Preferably, a strainer is connected to the bottom of the inner cavity of the shredding tank.

[0011] An intelligent control system for a feed preparation device includes a data acquisition module, an analysis module, a comparison module, and a regulation module;

[0012] The data acquisition module acquires the self-state parameters of the driving motor during operation and transmits the self-state parameters to the analysis module;

[0013] The analysis module establishes a data analysis model for the self-state parameters of the driving motor during operation, generates a monitoring index, and transmits the monitoring index to the comparison module;

[0014] The comparison module compares the monitoring index generated by the operation of the driving motor with the reference threshold of the monitoring index, generates an operation state signal, and transmits the operation state signal to the regulation module;

[0015] The regulation module, when receiving a low operation state signal, intelligently regulates the rotation speed of the driving motor.

[0016] Preferably, the self-state parameters include the over-temperature operation duration, the number of current overloads, and the number of abnormal bearing vibrations. After acquisition, the data acquisition module respectively calibrates the over-temperature operation duration, the number of current overloads, and the number of abnormal bearing vibrations as CWt, GZt, and ZDt.

[0017] Preferably, the logic for obtaining the over-temperature operation duration is as follows:

[0018] Obtain the driving motor operating temperatures at different moments within time t, calibrate the driving motor operating temperatures as Tx, where x represents the number of the driving motor operating temperature at different moments, x = 1, 2, 3, 4, ……, F, and F is a positive integer. Set the temperature reference threshold for the driving motor operating temperature and calibrate it as Ty. When Tx is less than Ty, it indicates that the driving motor operating temperature is normal and there is no over-temperature operation. When Tx is greater than or equal to Ty, it indicates that the driving motor operating temperature is abnormal and is in over-temperature operation. Compare the obtained Tx and Ty and calibrate the duration when Tx is greater than Ty as Tm, where m represents the numbering of the times when Tx is greater than Ty, m = 1, 2, 3, 4, ……, N, and N is a positive integer. Then the expression for calculating the driving motor over-temperature duration is: ;

[0019] The logic for obtaining the number of current overloads is as follows:

[0020] Obtain the current during the operation of the driving motor at different moments within time t, calibrate the current during the operation of the driving motor as It, and calibrate the rated current of the driving motor as Ie. Compare the obtained It with Ie. If It is greater than Ie, it indicates that the driving motor current is overloaded. If It is less than or equal to Ie, it indicates that the driving motor current is not overloaded. Mark the current during the operation of the driving motor when It is greater than Ie, and count the number of marked currents to obtain the number of current overloads GZt;

[0021] The logic for obtaining the number of abnormal bearing vibrations is as follows:

[0022] Obtain the vibration amplitude of the bearing at different moments within time t, calibrate the vibration amplitude of the bearing as Fd, and calibrate the maximum normal vibration amplitude of the bearing as Fmax. Compare the obtained Fd with Fmax. If Fd is greater than Fmax, it indicates that the bearing has abnormal vibration. If Fd is less than or equal to Fmax, it indicates that the bearing has normal vibration. Mark the vibration of the bearing when Fd is greater than Fmax, and count the number of marked vibrations to obtain the number of abnormal bearing vibrations ZDt.

[0023] Preferably, after the analysis module obtains the over-temperature operation duration CWt, the number of current overloads GZt, and the number of abnormal bearing vibrations ZDt, it establishes a data analysis model and generates a monitoring index , and the formula based on it is:

[0024] , where in the formula, 、 、 They are the preset proportionality coefficients of the over-temperature operation duration CWt, the number of current overloads GZt, and the number of abnormal bearing vibrations ZDt, respectively, and 、 、 are all greater than 0.

[0025] Preferably, after the comparison module obtains the monitoring index generated by the operation of the drive motor, it compares the monitoring index with the reference threshold of the monitoring index. If the monitoring index is greater than or equal to the reference threshold of the monitoring index, the comparison module generates a low operating state signal and transmits the signal to the regulation module. If the monitoring index is less than the reference threshold of the monitoring index, the comparison module generates a high operating state signal and transmits the signal to the regulation module.

[0026] Preferably, when the regulation module receives the low operating state signal, it sends an instruction to the drive motor to regulate the speed of the drive motor so that the monitoring index generated by the operation of the drive motor is less than the reference threshold of the monitoring index.

[0027] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0028] The present invention provides cutting support points through the first movable baffle and the second movable baffle, greatly improving the cutting efficiency of straw. By adjusting the motor to drive the threaded rod to rotate and drive the first movable baffle and the second movable baffle to approach the cutter between them at the same time, the gap between the first movable baffle and the second movable baffle is reduced, and the passing rate of straw through the gap is reduced, which can further improve the cutting efficiency of straw;

[0029] The present invention analyzes the operating state of the drive motor. When the drive motor is in the low operating state signal, the speed of the drive motor is regulated, thereby adjusting the operating state of the drive motor. When the drive motor is in an abnormal operating state, it is timely detected through the intelligent control system, and the abnormal operating state of the drive motor is adjusted, effectively preventing the drive motor from being in an abnormal operating state for a long time and accelerating the damage rate of the drive motor, and extending the service life of the drive motor.

[0041] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these exemplary embodiments are provided so that the present disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repeated description will be omitted.

[0042] In addition, the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the example embodiments of the present disclosure. However, those skilled in the art will recognize that one or more of the specific details may be omitted in practicing the technical solutions of the present disclosure, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0043] The present invention provides an intelligent device for a feed preparation device as Figure 1-7 shown, which includes a shredding tank 1, a driving motor 2, and cutting knives 3 that are annularly arrayed outside the output shaft of the driving motor 2. The cutting knives 3 are evenly distributed from top to bottom. An installation frame is provided at the top of the shredding tank 1, the driving motor 2 is installed on the installation frame, and a first movable baffle 4 and a second movable baffle 5 that are annularly arrayed are respectively provided at the top and bottom of the cutting knives 3. A gap is formed between the first movable baffle 4 and the second movable baffle 5, and the cutting knives 3 are respectively arranged in the corresponding gaps. An adjusting mechanism 6 for adjusting the size of the gap between the first movable baffle 4 and the second movable baffle 5 is provided between the first movable baffle 4 and the second movable baffle 5;

[0044] The adjusting mechanism 6 includes a fixed frame 61 connected in the shredding tank 1, an adjusting motor 62 installed on the top of the installation frame, and a threaded rod 63 connected to the end of the output shaft of the adjusting motor 62. The threaded rod 63 penetrates through the first movable baffle 4 and the second movable baffle 5 at the corresponding positions. The thread directions at the corresponding positions of the first movable baffle 4 are opposite to those at the corresponding positions of the second movable baffle 5. When the adjusting motor 62 operates, it drives the first movable baffle 4 and the second movable baffle 5 to approach the cutting knives 3 between them simultaneously or move away from the cutting knives 3 between them simultaneously. A strainer 7 is connected to the bottom of the inner cavity of the shredding tank 1.

[0045] The specific implementation manner is as follows: In actual use, the straw is put into the shredding tank 1, the driving motor 2 is turned on to drive the cutting knives 3 to rotate, and the straw can be cut by the rotating cutting knives 3. During the cutting process, the first movable baffle 4 and the second movable baffle 5 provide cutting support points, which can greatly improve the cutting efficiency of the straw. To further improve the cutting efficiency of the straw, the adjusting motor 62 is used to drive the threaded rod 63 to rotate, which drives the first movable baffle 4 and the second movable baffle 5 to approach the cutting knives 3 between them simultaneously, reducing the gap between the first movable baffle 4 and the second movable baffle 5. As Figure 6 shown in Figure 7 , the passing rate of the straw through the gap is reduced, which can further improve the cutting efficiency of the straw. When the straw is cut into smaller particles, it is exposed through the strainer 7, and then the cut straw can be collected.

[0046] The present invention provides an intelligent control system for a feed preparation device as shown in Figure 8 Figure 4, which includes a data acquisition module 100, an analysis module 200, a comparison module 300, and a regulation module 400;

[0047] The data acquisition module 100 collects its own state parameters when the driving motor 2 is running, and transmits its own state parameters to the analysis module 200;

[0048] The own state parameters include the over-temperature operation duration, the number of current overloads, and the number of abnormal bearing vibrations. After collection, the data acquisition module 100 labels the over-temperature operation duration, the number of current overloads, and the number of abnormal bearing vibrations as CWt, GZt, and ZDt respectively;

[0049] It should be noted that when the driving motor 2 operates at high load, situations such as over-stable operation, current overload, and abnormal bearing vibration will occur;

[0050] When the operating temperature of the driving motor 2 is too high, the following effects may be caused to the driving motor 2:

[0051] Insulation damage: High temperature will damage the insulation material inside the driving motor 2, and the thermal stability of the insulation material will decrease, which may lead to insulation breakdown or insulation aging, increasing the risk of failure of the driving motor 2;

[0052] Coil burnout: Excessive temperature will cause the coil of the driving motor 2 to overheat, exceeding its rated temperature, which may lead to insulation burnout, short circuit or sparking of the coil, resulting in the failure of the driving motor 2;

[0053] Efficiency reduction: High temperature will increase the internal resistance of the driving motor 2, resulting in a decrease in the energy conversion efficiency. The driving motor 2 will consume more energy when operating at high temperature, while the output power may decrease;

[0054] Thermal expansion of mechanical components: High temperature will cause thermal expansion of the mechanical components inside the driving motor 2, such as bearings, transmission parts, etc. Excessive thermal expansion may cause the bearings to be too tight or too loose, increasing the risk of wear and failure;

[0055] Shorter lifespan: Long-term high-temperature operation will accelerate the aging and wear of the internal components of the driving motor 2, which may lead to a shorter lifespan of the driving motor 2;

[0056] The logic for obtaining the over-temperature operation duration is as follows:

[0057] Obtain the operating temperature of the driving motor 2 at different times within t time, calibrate the operating temperature of the driving motor 2 as Tx, where x represents the number of the operating temperature of the driving motor 2 at different times, x = 1, 2, 3, 4, ……, F, and F is a positive integer. Set a temperature reference threshold for the operating temperature of the driving motor 2 and calibrate it as Ty. When Tx is less than Ty, it indicates that the operating temperature of the driving motor 2 is normal and there is no overheating operation. When Tx is greater than or equal to Ty, it indicates that the operating temperature of the driving motor 2 is abnormal and it is in overheating operation. Compare the obtained Tx and Ty and calibrate the duration when Tx is greater than Ty as Tm, where m represents the numbering of the times when Tx is greater than Ty, m = 1, 2, 3, 4, ……, N, and N is a positive integer. Then the expression for calculating the overheating duration of the driving motor 2 is: ;

[0058] Current overload will have the following effects on the driving motor 2:

[0059] Coil overheating: When the current exceeds the rated current of the driving motor 2, the coils inside the driving motor 2 will carry too much current, which will cause the coils to overheat, leading to the aging of the insulation material, the burning of the coils, and even the risk of fire;

[0060] Wire damage: Excessive current will generate additional heat and voltage drop on the wires inside the driving motor 2. If the wires are not sufficient to withstand the overload current, the wires may be damaged or even burned out, resulting in a circuit interruption or short circuit;

[0061] Power supply instability: Current overload may cause the power supply voltage to drop, resulting in unstable power supply for the driving motor 2. Unstable power supply will affect the normal operation of the driving motor 2, which may lead to performance degradation or failure;

[0062] Dynamic imbalance: Current overload will cause the driving motor 2 to generate an uneven magnetic field, making the rotating components such as the rotor of the driving motor 2 have dynamic imbalance. The imbalance will cause mechanical vibration, noise, and uneven load, damaging the bearings and transmission components of the driving motor 2;

[0063] Damage to the driving motor 2: Long-term current overload will cause various components inside the driving motor 2 to work under overload, resulting in fatigue and wear of mechanical components, reducing the life of the driving motor 2. If the current overload lasts for a long time or is too severe, it may cause damage to the driving motor 2 and require replacement or repair;

[0064] The logic for obtaining the number of current overloads is as follows:

[0065] Obtain the current of the drive motor 2 during operation at different times within time t. Calibrate the current during the operation of the drive motor 2 as It, and calibrate the rated current during the operation of the drive motor 2 as Ie. Compare the obtained It with Ie. If It is greater than Ie, it indicates that the current of the drive motor 2 is overloaded. If It is less than or equal to Ie, it indicates that the current of the drive motor 2 is not overloaded. Mark the current of the drive motor 2 when It is greater than Ie, and count the number of marked currents to obtain the number of current overloads GZt;

[0066] When the vibration rate of the bearing of the drive motor 2 is on the high side, it may cause the following impacts on the drive motor 2:

[0067] Premature failure: A high vibration rate indicates that there may be problems with the bearing, such as wear, looseness, damage, or poor lubrication, etc. These problems may lead to the premature failure of the bearing and shorten the service life of the drive motor 2;

[0068] Efficiency reduction: Vibration will cause abnormal friction and impacts between the internal mechanical components of the drive motor 2, increasing energy loss. This may lead to a reduction in the efficiency of the drive motor 2, an increase in power consumption, and energy waste;

[0069] Unstable operation: A high vibration rate may cause the operation of the drive motor 2 to be unstable and its performance to decline. The drive motor 2 may exhibit problems such as flutter, jitter, and imbalance, affecting its normal operation and precise control;

[0070] Reduced accuracy: Vibration will cause unbalanced bearing loads and shaft misalignment problems of the rotating components of the drive motor 2, resulting in the offset and swing of the rotating shaft. This may lead to a reduction in the accuracy of the torque and speed output by the drive motor 2 and affect the work quality;

[0071] The logic for obtaining the number of abnormal vibrations of the bearing is as follows:

[0072] Obtain the vibration amplitude of the bearing at different times within time t. Calibrate the vibration amplitude of the bearing as Fd, and calibrate the maximum normal vibration amplitude of the bearing as Fmax. Compare the obtained Fd with Fmax. If Fd is greater than Fmax, it indicates abnormal vibration of the bearing. If Fd is less than or equal to Fmax, it indicates normal vibration of the bearing. Mark the vibration of the bearing when Fd is greater than Fmax, and count the number of marked vibrations to obtain the number of abnormal vibrations of the bearing ZDt;

[0073] It should be noted that the vibration amplitude of the bearing is obtained through a vibration sensor. A vibration sensor is a device specifically used to measure vibration. Common vibration sensors include acceleration sensors, velocity sensors, and displacement sensors. These sensors can be installed on the bearing of the drive motor 2 to measure the vibration condition of the bearing;

[0074] The analysis module 200 establishes a data analysis model for the self-state parameters of the driving motor 2 during operation, generates a monitoring index, and transmits the monitoring index to the comparison module 300;

[0075] After the analysis module 200 obtains the over-temperature operation duration CWt, the number of current overloads GZt, and the number of abnormal bearing vibrations ZDt, it establishes a data analysis model and generates a monitoring index , and the formula is:

[0076] , where , , are the preset proportionality coefficients of the over-temperature operation duration CWt, the number of current overloads GZt, and the number of abnormal bearing vibrations ZDt respectively, and , , are all greater than 0;

[0077] It can be seen from the formula that the longer the over-temperature operation duration, the more the number of current overloads, and the more the number of abnormal bearing vibrations, that is, the larger the performance value of the monitoring index , indicating that the operating state of the driving motor 2 is worse. The shorter the over-temperature operation duration, the fewer the number of current overloads, and the fewer the number of abnormal bearing vibrations, that is, the smaller the performance value of the monitoring index , indicating that the operating state of the driving motor 2 is better;

[0078] The comparison module 300 compares the monitoring index generated by the operation of the driving motor 2 with the monitoring index reference threshold, generates an operation state signal, and transmits the operation state signal to the regulation module 400;

[0079] After the comparison module 300 obtains the monitoring index generated by the operation of the driving motor 2, it compares the monitoring index with the monitoring index reference threshold. If the monitoring index is greater than or equal to the monitoring index reference threshold, it indicates that the operating state of the driving motor 2 is poor. A low operating state signal is generated by the comparison module 300 and transmitted to the regulation module 400. If the monitoring index is less than the monitoring index reference threshold, it indicates that the operating state of the driving motor 2 is good. A high operating state signal is generated by the comparison module 300 and transmitted to the regulation module 400;

[0080] When the regulation module 400 receives the low operating state signal, it intelligently regulates the speed of the driving motor 2;

[0081] When the control module 400 receives a low operating state signal, it sends an instruction to the drive motor 2 to timely adjust the speed of the drive motor 2, so that the monitoring index generated by the operation of the drive motor 2 is less than the monitoring index reference threshold, thereby adjusting the operating state of the drive motor 2. In this way, when the drive motor 2 is in an abnormal operating state, it can be timely detected through the intelligent control system, and the abnormal operating state of the drive motor 2 is adjusted, effectively preventing the drive motor 2 from being in an abnormal operating state for a long time, accelerating the damage rate of the drive motor 2, and extending the service life of the drive motor 2;

[0082] In the present invention, by analyzing the operating state of the drive motor 2, when the drive motor 2 is in a low operating state signal, the speed of the drive motor 2 is adjusted, thereby adjusting the operating state of the drive motor 2. When the drive motor 2 is in an abnormal operating state, it can be timely detected through the intelligent control system, and the abnormal operating state of the drive motor 2 is adjusted, effectively preventing the drive motor 2 from being in an abnormal operating state for a long time, accelerating the damage rate of the drive motor 2, and extending the service life of the drive motor 2.

[0083] The above formulas are all dimensionless and take their numerical values for calculation. The formula is a formula obtained by collecting a large amount of data and performing software simulation to obtain the closest real situation. The preset parameters in the formula are set by those skilled in the art according to the actual situation.

[0084] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
