Description

Technical Field

[0001] The present application relates to the technical field of electric wool shears, and in particular to a control method, system, intelligent terminal and storage medium for electric wool shears. Background Art

[0002] Electric wool shears are auxiliary tools for shearing wool and have the advantage of high shearing efficiency.

[0003] In the related art, electric wool shears drive the trimming blades to move in an offset manner through a driving motor, so that the two overlapping trimming blades form a shearing action during the offset movement to achieve the trimming of the wool. The trimming blades are subject to less resistance when moving at no load, and the resistance generated when shearing the wool is greater, which can easily cause the driving motor to heat up.

[0004] Regarding the above-mentioned related technologies, when the wool shears work for a long time, the heat generated by the drive motor gradually increases with accumulation, which is likely to affect the normal operation of the electric drive motor and other internal electronic components. Summary of the Invention

[0005] In order to prevent the electric wool shears from being in a high temperature state during operation, the present application provides an electric wool shears control method, system, intelligent terminal and storage medium.

[0006] In a first aspect, the present application provides a method for controlling an electric wool shear, which adopts the following technical solution:

[0007] A method for controlling an electric wool shear, comprising:

[0008] Obtain the motor start signal of the electric wool shears and the shearing resistance value of the trimming blade;

[0009] According to the motor start signal, the motor is instructed to rotate to drive the trimming blade to cut, and at the same time, the driving motor drives the preset heat dissipation blades to rotate synchronously;

[0010] Comparing the shear resistance value with a preset operating resistance value to determine whether the shear resistance value is less than the preset operating resistance value;

[0011] When the shear resistance value is equal to or greater than the preset operating resistance value, an adjustment signal is output;

[0012] Based on the adjustment signal, the preset switching device is instructed to switch the heat dissipation blade to the speed adjustment device that rotates asynchronously with the motor, and the speed adjustment device is instructed to drive the heat dissipation blade to rotate;

[0013] According to the shear resistance value and the preset adjustment speed matching analysis, the heat dissipation adjustment speed of the heat dissipation blade is determined;

[0014] The speed regulating device preset based on the heat dissipation regulating speed indication regulates the speed of the heat dissipation blades.

[0015] By adopting the above technical solution, when the motor starts, it drives the trimming blade to shear, and drives the heat dissipation blade to rotate synchronously to form a heat dissipation airflow for heat dissipation, so that heat is not easily accumulated and causes the temperature to continue to rise. When wool shearing is performed, the indication switching device switches the heat dissipation blade to the speed regulating device, and instructs the speed regulating device to increase the speed of the heat dissipation blade to increase the heat dissipation efficiency of the electric shearing sheep when shearing wool.

[0016] Optionally, a trimming blade adjustment method is further included. When the trimming signal is output, the trimming blade adjustment method includes:

[0017] Get the shearing frequency of the trimming blade;

[0018] Compare and analyze the cutting frequency with the preset jamming frequency range to determine whether the cutting frequency is consistent with the preset jamming frequency;

[0019] If the cutting frequency is inconsistent with the preset jamming frequency, a normal operation prompt will be issued;

[0020] If the shearing frequency is consistent with the preset jamming frequency, a jamming prompt will be issued and the contact distance between the electric wool shears and the sheep will be obtained;

[0021] Determine whether the contact distance is greater than a preset reference distance;

[0022] When the contact distance is greater than a preset reference distance, the corresponding trimming blade is instructed to rotate to a preset adjustment inclination value to clean the residual wool on the trimming blade.

[0023] By adopting the above technical solution, the electric wool shears can be adjusted when the trimming blades are blocked due to wool clogging during the trimming process. When the electric wool shears are removed from the sheep's trimming contact position, the contact distance is greater than the preset reference distance. At this time, the fitted trimming blades are rotated and adjusted to be spaced apart from each other, so that the wool stuck between the trimming blades is loosened, which facilitates the wool to fall off the trimming blades by itself, and helps to reduce the probability of the motor's rotation being blocked and the increase in heat due to jamming.

[0024] Optionally, when the contact distance is greater than a preset reference distance, the method further includes:

[0025] Get the tilt posture of the electric wool shears;

[0026] Comparing and analyzing the tilting posture with the preset blockage clearing posture to determine whether the tilting posture fits the preset blockage clearing posture;

[0027] If the tilting posture does not fit the preset blockage cleaning posture, the motor is instructed to keep driving the trimming blade to trim;

[0028] If the tilt posture matches the preset blockage cleaning posture, the corresponding trimming blade is instructed to rotate at a preset adjustment tilt angle value, and it is determined whether the tilt posture is within a preset posture angle range;

[0029] When the tilting posture is not within the preset tilting posture angle range, the trimming blades are instructed to fit together, and the motor is instructed to keep driving the trimming blades to trim.

[0030] By adopting the above technical solution, when the electric wool shears is clogged with wool and causes the inspection and trimming blade to be stuck, the moving posture of the electric wool shears is analyzed. When the electric wool shears fits the preset blockage cleaning posture, the fitting trimming blade is instructed to rotate to the preset adjustment inclination value to facilitate cleaning the clogged wool. When the electric wool shears does not fit the preset blockage cleaning posture, it means that the staff has not cleaned the electric wool shears. At this time, the trimming blade is not rotated and adjusted, which reduces the probability of misadjustment of the trimming blade and keeps the trimming blade driven without affecting the subsequent wool shearing operation.

[0031] Optionally, a method for guiding the heat dissipation airflow blown out by the heat dissipation blades is further included, and the heat dissipation airflow guiding method includes:

[0032] Obtain the air flow temperature blown out by the electric wool shears and the ambient temperature;

[0033] Comparing the airflow temperature with a preset comfort temperature to determine whether the airflow temperature is greater than the preset comfort temperature;

[0034] If the air flow temperature is equal to or lower than the preset comfortable temperature, the electric wool shears are instructed to transmit the heat dissipation air flow to the preset first heat dissipation hole and blow it out toward the wool shearing location;

[0035] If the air flow temperature is greater than the preset comfortable temperature, the electric wool shear is instructed to blow the heat dissipation air flow toward the preset second heat dissipation hole toward the side away from the sheep, and compare the air flow temperature with the ambient temperature;

[0036] When the air flow temperature is greater than the ambient temperature, the temperature difference between the air flow temperature and the ambient temperature is calculated;

[0037] The temperature difference is compared and analyzed with the preset neutralization difference to determine whether to instruct the electric wool shears to transmit the airflow to the preset first heat dissipation hole for blowing out or to transmit the airflow to the preset second heat dissipation hole for blowing out.

[0038] By adopting the above technical solution, the blown air flow is analyzed, and the air flow with a temperature higher than the comfortable temperature is blown out from the second heat dissipation hole toward the side away from the sheep, so that the sheep are not easily affected by the higher temperature air flow and move around. The air flow with a temperature lower than the lower temperature is blown out from the first heat dissipation hole, so that the heat dissipation air flow can clean the wool at the wool shearing place, which helps to reduce the risk of wool falling on the electric wool shears during shearing, thereby reducing the probability of the motor heating up due to clogging and jamming of the shearing blades.

[0039] Optionally, before directing the airflow toward the sheared wool, the method further comprises:

[0040] Get the shearing movement trajectory of the electric wool shears;

[0041] Compare and analyze the trimming movement trajectory with the preset trimming part trajectory to determine the smooth trimming area and the tortuous trimming area;

[0042] Matching the smooth trimming area, the zigzag trimming area, and a preset trimming speed to determine a smooth trimming speed and a zigzag trimming speed of the trimming blade;

[0043] The drive motor adjusts the drive speed of the trimming blade based on the smooth trimming speed and the zigzag trimming speed instructions.

[0044] By adopting the above technical solution, the wool shears analyze the trimming trajectory during the wool shearing process. When the wool shears are trimming a smooth area, the shearing speed of the trimming blade is increased, so that the trimming rate of the wool shears is improved. When trimming in a smooth trimming area, there is no need to frequently change the trimming direction, which is not likely to cause the wool and the trimming blade to get stuck, thereby helping to reduce the increase in motor temperature caused by the jam. When trimming in a curved trimming area, the shearing speed of the wool blade is reduced, so that when the wool blade gets stuck, the motor can be easily stopped and repaired due to the relatively low shearing movement speed of the trimming blade.

[0045] Optionally, a method for adjusting the size of the heat dissipation airflow is further included, and the method for adjusting the size of the airflow includes:

[0046] Obtaining a heat dissipation wind force value of the heat dissipation airflow in the preset first heat dissipation hole or the preset second heat dissipation hole;

[0047] The baseline cleaning airflow value is determined based on the heat dissipation wind force value and the preset wool length mean value.

[0048] Compare and analyze the baseline cleaning airflow value and the cooling wind force value to determine whether the baseline cleaning airflow value is greater than the cooling wind force value;

[0049] When the reference cleaning airflow value is greater than the cooling wind force value, the difference between the reference cleaning airflow value and the cooling wind force value is calculated to determine the airflow adjustment value;

[0050] Analyze the matching between the airflow adjustment value and the preset adjustment speed to determine the target speed;

[0051] Calculate the difference between the target speed and the heat dissipation adjustment speed to determine the speed to be increased;

[0052] The speed regulating device preset based on the speed indication to be increased drives the rotation of the heat dissipating blades.

[0053] By adopting the above technical solution, the wind force value of the heat dissipation airflow transmitted to the first heat dissipation hole or the second heat dissipation hole is detected. On the basis of the wind force value that can ensure heat dissipation, it is analyzed whether the heat dissipation airflow can be blown during the wool shearing process to achieve blowing and cleaning of the wool toward the side, so that the heat dissipation effect can be further improved while reducing the probability of the wool causing obstruction to the wool shearing.

[0054] Optionally, when determining the airflow adjustment value, the following steps are also included:

[0055] Get the remaining power of the electric wool shears;

[0056] Comparing and analyzing the remaining power and a preset sufficient power value to determine whether the remaining power is less than the sufficient power;

[0057] If the remaining power is less than the sufficient power, determining whether the remaining power falls within a preset low power range;

[0058] When the remaining power falls within the preset low power range, the cooling wind speed value remains unchanged;

[0059] When the remaining power does not fall within the preset low power range, the speed regulating device is instructed to adjust according to the target speed;

[0060] If the remaining power is equal to or greater than the sufficient power, the speed regulating device is instructed to adjust according to the target speed.

[0061] By adopting the above technical solution, the remaining power of the electric wool shears during the trimming process is detected and analyzed. When the remaining power is sufficient, the heat dissipation wind force value of the heat dissipation airflow is compared and analyzed with the reference cleaning airflow value to determine whether the speed adjustment device needs to be adjusted. When the remaining power is within a low power range, the wind force is not adjusted, so as to maintain heat dissipation while extending the working time of the electric wool shears.

[0062] In a second aspect, the present application provides an electric wool shear control system, which adopts the following technical solution:

[0063] An electric wool shears control system, comprising:

[0064] An acquisition module is used to obtain a motor start signal and a shear resistance value;

[0065] A memory for storing a program of any one of the electric wool shearing control methods;

[0066] The processor and the program in the memory can be loaded and executed by the processor to implement any one of the electric wool shearing control methods.

[0067] By adopting the above technical solution, the motor start-up signal and the shearing resistance value are analyzed. When the motor starts, it drives the shearing blade to shear and drives the heat dissipation blades to rotate synchronously to form a heat dissipation airflow for heat dissipation, so that heat is not easily accumulated and causes the temperature to continue to rise. When shearing wool, the instruction switching device switches the heat dissipation blades to the speed regulating device, and instructs the speed regulating device to increase the speed of the heat dissipation blades to increase the heat dissipation efficiency of the electric shearing sheep when shearing wool.

[0068] In a third aspect, the present application provides a smart terminal that adopts the following technical solution:

[0069] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute any one of the above-mentioned electric wool shearing control methods.

[0070] By adopting the above technical solution and using the intelligent terminal, when the electric wool shears are started, the motor synchronously drives the trimming blades and the heat dissipation blades to rotate to achieve heat dissipation. When the trimming blades and the wool are trimmed, the switching device switches the heat dissipation blades to the speed regulating device for asynchronous drive, and increases the turning speed of the heat dissipation blades, so that the heat dissipation efficiency is further improved.

[0071] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which has the characteristic of preventing the electric wool shears from being in a high temperature state during operation, and adopts the following technical solution:

[0072] A computer-readable storage medium stores a computer program capable of being loaded by a processor and executing any one of the above-mentioned electric wool shearing control methods.

[0073] By adopting the above technical solution, a computer program for the control method of the electric wool shears is stored in a storage medium. By loading the computer program, when the electric wool shears are started, the motor synchronously drives the trimming blades and the heat dissipation blades to rotate to achieve heat dissipation. When the trimming blades and wool are trimmed, the switching device switches the heat dissipation blades to the speed regulating device for asynchronous drive, and increases the rotation speed of the heat dissipation blades, so that the heat dissipation efficiency is further improved.

[0074] In summary, this application includes at least one of the following beneficial technical effects:

[0075] 1. When the motor starts, it drives the shearing blade to shear and drives the heat dissipation blade to rotate synchronously to form a heat dissipation airflow for heat dissipation, so that heat is not easily accumulated and the temperature continues to rise. When shearing the wool, the indicator switching device switches the heat dissipation blade to the speed regulating device and instructs the speed regulating device to increase the speed of the heat dissipation blade to increase the heat dissipation efficiency of the electric shearing sheep when shearing the wool;

[0076] 2. When the electric wool shears are blocked by wool during the shearing process, the shearing blades are adjusted. When the electric wool shears are removed from the shearing contact position of the sheep, the contact distance is greater than the preset reference distance. At this time, the shearing blades are rotated and adjusted so that the shearing blades are spaced apart from each other. The wool stuck between the shearing blades is loosened, making it easier for the wool to fall off the shearing blades. This helps reduce the probability of the motor being blocked and overheated due to the motor jam.

[0077] 3. Analyze the outgoing airflow, so that the airflow with a temperature higher than the comfortable temperature is blown out from the second heat dissipation hole toward the side away from the sheep, so that the sheep are less likely to move around due to the influence of the higher temperature airflow, and blow the airflow with a temperature lower than the comfortable temperature out from the first heat dissipation hole, so that the heat dissipation airflow can clean the wool at the wool shearing place, which helps to reduce the wool from falling on the electric wool shears during shearing, thereby reducing the probability of the shearing blade being blocked and causing the motor to heat up.

[0085] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0086] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0087] An embodiment of the present application discloses a control method for an electric wool shear. The method first obtains a motor start signal and a trimming blade resistance value of the electric wool shear. When the motor start signal is obtained, the motor is driven to cut the trimming blade while driving the heat dissipation blade to rotate synchronously. Then, it is determined whether the shearing resistance value of the trimming blade is greater than a preset operating resistance value. When the shearing resistance value is greater than the operating resistance value, the heat dissipation blade is switched from the motor to a preset speed adjustment device through a switching device pre-set on the electric wool shear, and the speed adjustment device is instructed to adjust the speed of the heat dissipation blade, so that the heat dissipation blade can be adjusted and generate different speeds, so that the heat dissipation blade can generate different wind speeds for heat dissipation, which helps to keep the motor and other internal electrical components working in a low temperature state.

[0088] Reference Figure 1 The method flow of the electric wool shearing control method includes the following steps:

[0089] Step S100: obtaining a motor start signal of the electric wool shears and a shearing resistance value of a trimming blade;

[0090] Electric wool shears are equipped with a motor that drives two mating shearing blades in a reciprocating cutting motion in opposite directions. When the control motor is activated, the electrical signal emitted is called the motor start signal. The shearing resistance value is the amount of resistance experienced by the shearing blades during movement. When the wool is not being sheared, the resistance value is low, while when the wool is being sheared, the resistance value is high. The resistance value can be obtained by pre-installing a damping sensor on the motor. The damping sensor detects the rotational damping force of the motor, thereby indirectly measuring the resistance transmitted by the shearing blades to the motor output shaft. The measured damping force is defined as the shearing resistance value.

[0091] Step S101: instructing the motor to rotate according to the motor start signal to drive the trimming blade to cut, and at the same time driving the motor to drive the preset heat dissipation blades to rotate synchronously;

[0092] The motor is a coaxial motor. The output shaft at one end of the motor forms a transmission connection with the trimming blade, and the other end of the motor's rotor output shaft forms a transmission connection with the heat dissipation blade. When the motor drives the trimming blade to perform shearing movement, it also drives the heat dissipation blade to rotate. The heat dissipation blade is a heat dissipation wheel structure. When the heat dissipation blade rotates, it generates an airflow blowing toward one side of the motor to transport the heat dissipated during the operation of the motor to the outside of the electric wool shears to achieve heat dissipation.

[0093] Step S102: comparing the shear resistance value with a preset operation resistance value to determine whether the shear resistance value is less than the preset operation resistance value;

[0094] The operating resistance value is the resistance value encountered when the trimming blade contacts the wool for shearing. The resistance value can be determined by recording and collecting data during the experiment by the staff. The purpose of judging whether the shearing resistance value is less than the preset operating resistance value is to further control the heat dissipation blades in the future.

[0095] Step S103: When the shear resistance value is equal to or greater than the preset operation resistance value, an adjustment signal is output;

[0096] If the shearing resistance value is equal to or greater than the preset operating resistance value, it means that the electric wool shears are inspecting the wool, the shearing blades are in contact with the wool and generate a certain shearing resistance, and an adjustment signal is output at this time.

[0097] Step S104: instructing a preset switching device to switch the heat dissipating blades to a speed regulating device that rotates asynchronously with the motor based on the adjustment signal, and instructing the speed regulating device to drive the heat dissipating blades to rotate;

[0098] The switching device is a clamping mechanism pre-installed on the heat dissipation blade, which is used to clamp the heat dissipation blade on the output shaft of the motor. The speed adjustment device is another speed-regulating motor pre-installed on the electric wool shears. The output shaft of the speed-regulating motor and the motor for driving the trimming blade are coaxially arranged. Initially, the speed adjustment device is in standby state. After receiving the adjustment signal, the switching device releases the connection between it and the motor and clamps it to the output shaft of the speed-regulating motor, and then rotates the heat dissipation blade through the speed-regulating motor.

[0099] Step S105: performing matching analysis based on the shear resistance value and the preset adjustment speed to determine the heat dissipation adjustment speed of the heat dissipation blades;

[0100] The adjustment speed is the rotational speed of the heat dissipation blades when the speed adjustment device is adjusting the rotation. The adjustment speed can be determined by establishing a speed adjustment database for matching. Different shear resistance values ​​and their mapped adjustment speeds are stored in the speed adjustment database. When the shear resistance value is input into the speed adjustment database, the corresponding adjustment speed is output. The output adjustment speed is defined as the heat dissipation adjustment speed. The adjustment speed is obtained for subsequent adjustment of the heat dissipation blades. It should be noted that the heat generated by the motor varies under different shear resistance values. The adjustment speed corresponding to the shear resistance value can be used to time the heat dissipation generated by the motor during wool shearing operations.

[0101] Step S106: the preset speed regulating device regulates the speed of the heat dissipation blades based on the heat dissipation speed regulation indication.

[0102] By rotating the heat dissipation adjustment speed obtained by matching in the speed adjustment database, the heat dissipation blades can output sufficient airflow for heat dissipation when the electric wool shears are shearing wool, so as to keep the motor in a low temperature state.

[0103] Reference Figure 2 , also includes a trimming blade adjustment method, when the trimming signal is output:

[0104] Step S200: obtaining the shearing frequency of the trimming blade;

[0105] The shearing frequency is the time period during which the shearing blade performs its reciprocating shearing motion. For example, the shearing blade's reciprocating shearing frequency is 5 times per second. The shearing frequency is determined by calculating the motor speed and the transmission ratio of the transmission mechanism. This means that the motor's rotational speed is detected and calculated using a corresponding computing chip installed in the electric wool shears.

[0106] Step S201: comparing and analyzing the cutting frequency with a preset freeze frequency range to determine whether the cutting frequency is consistent with the preset freeze frequency;

[0107] The jamming frequency range is the range of shearing frequency variations caused by the shear blade becoming stuck in the wool during shearing. This range is recorded by staff based on experimental data, and the specific frequency values ​​are not detailed here. Determining whether the shearing frequency is consistent with the jamming frequency allows for further control of the shear blade.

[0108] Step S202: If the cutting frequency is inconsistent with the preset freezing frequency, a normal operation prompt is issued;

[0109] If the shearing frequency is inconsistent with the preset jamming frequency, it means that the trimming blade is not jammed and is in normal working condition. At this time, no other control of the electric wool shears is required, and a normal operation prompt signal is issued.

[0110] Step S203: If the shearing frequency is consistent with the preset jamming frequency, a jamming prompt is issued and the contact distance between the electric wool shears and the sheep is obtained;

[0111] If the shearing frequency matches the preset jamming frequency, it indicates that the shearing blade has jammed during the shearing process. Wool may have been left on the shearing blade during the shearing process, causing a blockage. The shearing blade needs to be repaired and cleaned, and a jamming prompt is issued. When the jamming prompt is issued, the distance between the electric wool shear and the sheep is obtained and defined as the contact distance. The contact distance can be detected by pre-installing an infrared ranging sensor module on the electric wool shear.

[0112] Step S204: determining whether the contact distance is greater than a preset reference distance;

[0113] Step S205: When the contact distance is greater than the preset reference distance, the corresponding trimming blades are instructed to rotate to a preset adjustment angle value to clean the residual wool on the trimming blades.

[0114] Determining whether the contact distance is greater than a preset reference distance is done to determine whether the electric wool shears are currently operating in a wool-shearing state. The reference distance is a distance value set by the operator based on actual needs. In this embodiment, the basic distance value is zero. If the contact distance is equal to or less than the reference distance, the electric wool shears maintain contact with the sheep and are currently in a wool-shearing state. No further cleaning control is performed. If the contact distance is greater than the preset reference distance, the electric wool shears are moving away from the sheep. At this point, the shearing blades are stopped, and a micromotor pre-installed on the shears controls the two mating shearing blades to rotate one blade away from the other. The rotation angle is set by the operator based on actual needs and is defined as the adjusted tilt angle. At this point, a gap is formed between the two mating shearing blades to facilitate wool shedding. The operator can then blow air or poke residual wool to remove it from the shearing blades.

[0115] Reference Figure 3 , when the contact distance is greater than the preset reference distance, it also includes:

[0116] Step S300: obtaining the tilt posture of the electric wool shears;

[0117] The tilt angle is the tilt angle of the wool shears during the wool shearing process, and the tilt angle can be detected by pre-installing a micro gyroscope in the wool shears. In the subsequent embodiments of this application, the electric wool shears are all introduced as wool shears.

[0118] Step S301: comparing and analyzing the tilting posture with the preset blockage clearing posture to determine whether the tilting posture matches the preset blockage clearing posture;

[0119] The blockage cleaning posture is the tilting posture angle of the wool shears when cleaning wool, which is set by the staff. By comparing the tilting posture angle value corresponding to the tilting posture with the posture angle value corresponding to the blockage cleaning posture, it is determined whether the tilting posture fits the preset blockage cleaning posture. When the fitting degree exceeds 90%, it means that the tilting posture fits the blockage cleaning posture, otherwise, it does not fit.

[0120] Step S302: if the tilting posture does not match the preset blockage clearing posture, instructing the motor to keep driving the trimming blade to trim;

[0121] The tilted posture does not match the preset blockage cleaning posture, indicating that the wool shears have just moved away from the shearing position of the sheep. After observation, the staff determined that the jam did not affect the normal operation of the wool shears. The wool shearing work needs to be continued later, so the motor should be kept driving the shearing blades.

[0122] Step S303: If the tilt posture matches the preset blockage clearing posture, instruct the corresponding trimming blade to rotate at a preset adjustment tilt angle value, and determine whether the tilt posture is within a preset posture angle range;

[0123] If the tilted posture matches the preset blockage cleaning posture, it means that after observation, the staff needs to clean the shear blades and rotate the shears to the cleaning tilted posture for maintenance. At this time, the shear blades need to be controlled to stop cutting and rotate according to the adjusted tilt angle value. The tilted posture angle range is the tilt angle range within which the shears swing during the maintenance process. If it changes within this range, it means that the shears are still in maintenance. The analysis and comparison of the tilted posture angle range is to facilitate further control of the shear blades.

[0124] Step S304: when the tilting posture is not within the preset tilting posture angle range, instructing the trimming blades to be in contact with each other, and instructing the motor to keep driving the trimming blades to trim.

[0125] When the tilt posture is not within the preset tilt posture angle range, it means that the wool shears are cleaned. At this time, the tilted trimming blade is controlled to reset to fit with another blade, and the motor drives the trimming blade to cut again to continue the wool trimming operation.

[0126] Reference Figure 4 , and also includes a method for guiding the heat dissipation airflow blown out by the heat dissipation blades:

[0127] Step S400: obtaining the temperature of the air flow blown out by the electric wool shears and the ambient temperature;

[0128] Electric wool shears have cooling holes for dissipating airflow. The airflow temperature is the temperature of the air in the cooling holes. The ambient temperature is the temperature outside the wool shears. The airflow temperature and ambient temperature can be obtained by pre-installing temperature sensors on the wool shears.

[0129] Step S401: comparing the airflow temperature with a preset comfort temperature to determine whether the airflow temperature is greater than the preset comfort temperature;

[0130] The comfortable temperature is a relatively mild temperature that does not irritate the sheep during shearing. The airflow temperature is the temperature of the cooling airflow when it exits the heat dissipation holes. Determining whether the airflow temperature is greater than the preset comfortable temperature facilitates subsequent control of airflow transmission. In this embodiment, the heat dissipation holes include a first heat dissipation hole and a second heat dissipation hole. The first heat dissipation hole is located toward the shearing blade side of the shears, and the second heat dissipation hole is located toward the circumference of the shears.

[0131] Step S402: If the air flow temperature is equal to or lower than the preset comfortable temperature, the electric wool shears are instructed to transmit the heat dissipation air flow to the preset first heat dissipation hole and blow it toward the wool shearing location;

[0132] If the air flow temperature is equal to or lower than the preset comfortable temperature, it means that the temperature blown out of the heat dissipation hole will not irritate the sheep. At this time, the wall of the second heat dissipation hole is closed and the first heat dissipation hole is opened, so that the heat dissipation air flow is blown toward the trimming blade of the wool shears, thereby cleaning the wool in the trimming direction and helping to reduce the probability of wool clogging at the trimming location.

[0133] Step S403: If the airflow temperature is greater than the preset comfortable temperature, the electric wool shear is instructed to transmit the heat dissipation airflow to the preset second heat dissipation hole and blow it toward the side away from the sheep, and compare the airflow temperature with the ambient temperature;

[0134] If the airflow temperature is equal to or lower than the preset comfort temperature, it means that the heat dissipation airflow from the first vent will cause irritation to the sheep, making it difficult to keep them stable. In this case, the first vent is controlled to close and the second vent is opened, allowing the airflow to flow to the outside air and lowering the internal temperature of the wool shear. The purpose of comparing the ambient temperature and the airflow temperature is to further control the vents.

[0135] Step S404: when the air flow temperature is greater than the ambient temperature, calculating the temperature difference between the air flow temperature and the ambient temperature;

[0136] When the airflow temperature is greater than the ambient temperature, the difference between the ambient and airflow temperatures is small. Calculating the difference between the airflow temperature and the ambient temperature is to determine whether the airflow temperature will quickly reach the ambient temperature when it exits the heat dissipation holes. When the airflow temperature is equal to or less than the ambient temperature, the heat dissipation will not affect the environment, causing a temperature increase. This does not affect heat dissipation, and no further control is required.

[0137] Step S405: comparing and analyzing the temperature difference with the preset neutralization difference to determine whether to instruct the electric wool shears to transmit the airflow to the preset first heat dissipation hole for blowing out or to transmit the airflow to the preset second heat dissipation hole for blowing out.

[0138] The neutralization difference is the temperature value at which the heat dissipation airflow can quickly neutralize the temperature when it is output from the heat dissipation holes. The neutralization difference is set by the staff according to the actual situation, and the neutralization difference is relatively close to the temperature of the heat dissipation airflow.

[0139] When the temperature difference is equal to or less than the neutralization difference, it means that although the heat dissipation airflow has a higher temperature in the first heat dissipation hole or the second heat dissipation hole, it can quickly neutralize the temperature in the air when it is transmitted to the air and will not cause irritation to the sheep. At this time, controlling the heat dissipation airflow to blow out from the first heat dissipation hole can achieve heat dissipation while also cleaning the wool.

[0140] If the temperature difference is greater than the neutralization difference, it means that the heat dissipation airflow is not suitable for blowing out from the first heat dissipation hole. At this time, the first heat dissipation hole is controlled to be closed and the second heat dissipation hole is opened to discharge the heat dissipation airflow.

[0141] Reference Figure 5 , directing the airflow towards the sheared wool before blowing out, also includes:

[0142] Step S500: obtaining the trimming movement trajectory of the electric wool shears;

[0143] The shearing movement trajectory is the movement trajectory generated when the wool shears fit the sheep's body for shearing, and is obtained by installing a trajectory positioning module chip on the wool shears.

[0144] Step S501: comparing and analyzing the trimming movement trajectory with the preset trimming part trajectory to determine a smooth trimming area and a tortuous trimming area;

[0145] The trimming trajectory is the corresponding trimming trajectory when trimming different parts of the sheep. The trimming trajectory is recorded and stored by staff based on experiments. The corresponding trimming trajectories of different trimming areas are smooth trimming areas and zigzag trimming areas. Smooth trimming areas are relatively flat parts of the sheep, such as the back and flanks, and are relatively smooth when trimmed. Zigzag trimming areas are parts of the sheep with larger curvatures, such as the abdomen and the connection between the head and neck. By storing smooth trimming areas and zigzag trimming areas to establish a trimming trajectory database, when the corresponding trimming trajectory is input, it can be determined whether it belongs to the smooth trimming area or the zigzag trimming area.

[0146] Step S502: determining a smooth trimming speed and a zigzag trimming speed of a trimming blade based on the smooth trimming area, the zigzag trimming area and a preset trimming speed;

[0147] Step S503: Instructing the driving motor to adjust the driving speed of the trimming blade based on the smooth trimming speed and the zigzag trimming speed.

[0148] A trimming speed matching database is established, different trimming speeds are stored in the trimming speed matching database, and a mapping matching relationship is formed between the trimming speed and the smooth trimming area and the zigzag trimming area. The smooth trimming speed corresponds to the smooth trimming area, and the zigzag trimming speed corresponds to the zigzag trimming area. When a smooth trimming area or a zigzag trimming area is input into the trimming speed matching database, the corresponding trimming speed can be output. It should be noted that the smooth trimming speed is relatively fast and the zigzag trimming speed is relatively slow, so that when trimming in the smooth area, the trimming speed can be increased and the trimming blade is not easily blocked by wool due to the large arc during movement. Slowing down the trimming speed in the zigzag trimming area makes it convenient to quickly reduce the cutting speed of the trimming blade when a jam occurs.

[0149] Reference Figure 6 , and also includes a method for adjusting the size of the heat dissipation airflow:

[0150] Step S600: obtaining a heat dissipation wind force value of the heat dissipation airflow in the preset first heat dissipation hole or the preset second heat dissipation hole;

[0151] The heat dissipation wind force value is the wind force of the heat dissipation airflow blown out of the first heat dissipation hole or the second heat dissipation hole, and is obtained by pre-installing a micro wind force detection sensor for detection.

[0152] Step S601: Analyzing the heat dissipation wind force value and the preset wool length mean value to determine a reference cleaning airflow value;

[0153] The average wool length is the average wool length of different types of sheep in different periods. It is determined by establishing a cleaning database, storing different types of sheep and corresponding growth periods in the cleaning database, and also storing the airflow size required for blowing cleaning of wool of different lengths. The airflow size is defined as a baseline cleaning airflow value. When the type of sheep and the growth period are input, the corresponding baseline cleaning airflow value can be output.

[0154] Step S602: Compare and analyze the baseline cleaning airflow value and the cooling wind force value to determine whether the baseline cleaning airflow value is greater than the cooling wind force value;

[0155] Comparing the cooling wind force value with the baseline cleaning airflow is to make further adjustments to the cooling airflow later.

[0156] Step S603: When the reference cleaning airflow value is greater than the cooling wind force value, a difference calculation is performed between the reference cleaning airflow value and the cooling wind force value to determine an airflow adjustment value;

[0157] When the baseline cleaning airflow value is greater than the heat dissipation wind force value, it means that the heat dissipation wind force value blown out of the first heat dissipation hole is relatively small. At this time, the difference between the baseline cleaning airflow value and the heat dissipation wind force value is calculated to determine the difference between the heat dissipation wind force value and the baseline cleaning airflow value, which is defined as the airflow adjustment value.

[0158] Step S604: performing matching analysis based on the airflow adjustment value and the preset adjustment speed to determine the target speed;

[0159] Step S605: Calculating the difference between the target speed and the heat dissipation adjustment speed to determine the speed to be increased;

[0160] A speed matching database is established, storing different airflow adjustment values ​​and corresponding adjustment speeds in the database, forming a one-to-one mapping relationship. When an airflow adjustment value is input, the corresponding adjustment speed is output, which is defined as the target speed. Once the target speed is determined, the difference between the target speed and the heat dissipation adjustment speed is calculated to determine the speed at which the heat dissipation blades need to rotate to achieve the corresponding airflow adjustment value, which is defined as the target speed increase.

[0161] Step S606: The speed regulating device preset based on the speed to be increased indicates the rotation of the heat dissipation blades.

[0162] After knowing that the speed is to be increased, the speed regulating device is controlled to rotate so that the heat dissipation blades reach the target speed, thereby forming a corresponding heat dissipation airflow to clean the wool and improve the heat dissipation effect.

[0163] Reference Figure 7 , when determining the airflow adjustment value, it also includes:

[0164] Step S700: obtaining the remaining power of the electric wool shears;

[0165] The remaining power is the current remaining battery power of the wool shears, which is obtained by installing a battery power detection chip in the battery and monitoring it.

[0166] Step S701: comparing and analyzing the remaining power and a preset sufficient power value to determine whether the remaining power is less than the sufficient power;

[0167] The sufficient power value is the value when the battery is at a relatively high power level, for example, the remaining power is 60%. The remaining power is compared with the sufficient power value to determine whether the remaining power value is less than the sufficient power value in order to facilitate further control of the heat dissipation blades.

[0168] Step S702: If the remaining power is less than the sufficient power, determine whether the remaining power falls within a preset low power range;

[0169] The low battery range is the range of values ​​where the battery is at a low level. The low battery range is set by the staff, for example, 30%. If the remaining power is less than the full power level, it means that the remaining power is not high. At this time, further determination is made to see if the remaining power falls within the preset low battery range to facilitate further control.

[0170] Step S7021: When the remaining power does not fall within the preset low power range, instructing the speed regulating device to adjust according to the target speed;

[0171] When the remaining power does not fall into the preset low power level, but the power is not low, and the trimming operation can be maintained, the rotation speed of the heat dissipation blades can be adjusted so that the heat dissipation blades generate a larger airflow to clean the wool. At this time, the speed adjustment device is continued to be instructed to adjust the speed of the heat dissipation blades.

[0172] Step S7022: If the remaining power is equal to or greater than the sufficient power, instruct the speed regulating device to adjust according to the target speed.

[0173] If the remaining power is equal to or greater than the sufficient power, it means that the remaining power of the battery is high at this time, and can provide sufficient power to control the heat dissipation blades to rotate at a high speed, so as to provide a larger wind force to blow and clean the wool.

[0174] Step S703: When the remaining power falls within the preset low power range, the cooling wind speed value is kept unchanged;

[0175] When the remaining power falls within the preset low power range, it means that the remaining power is insufficient, and the trimming blade is mainly controlled to trim, and the speed adjustment of the heat dissipation blade is no longer increased, so as to obtain a longer working time.
