Description

Technical Field

[0001] The present application relates to the field of intelligent agricultural technology, and in particular, to an auger type identification device and method. Background Art

[0002] In the development of modern smart agriculture, the application of spreaders has become increasingly widespread. In the spreader, the auger, as a core component, undertakes the key task of transmitting the spread material. In order to meet the needs of different spread amounts, augers with different spiral blade densities are usually equipped, and different types of augers can achieve regulation of the spread amount through different spiral blade densities. However, in the prior art, the replacement of different types of augers for spreaders mostly relies on manual operation. In the process of manual replacement, replacement errors are inevitable. Once an error occurs, the spreader will not be able to operate according to the established spread requirements in subsequent operations, especially in large-scale seeding operations, and may even cause large economic losses.

[0003] In view of this, it is particularly urgent to propose a device and method that can identify the type of an auger in operation, so as to effectively avoid the problem of the wrong type of an installed auger. Summary of the invention

[0004] The present application provides an auger type identification device and method, which can identify the type of an auger in operation, avoid losses caused by using an inappropriate auger type, and improve the accuracy of sowing.

[0005] In the first aspect, a device for identifying the type of auger is provided, comprising: a magnetic component, comprising at least one magnetic element, the magnetic element is arranged on the top blade of the auger, and is used to generate a magnetic signal; a sensor component, the sensor component is arranged on the outer shell of the auger, and is located on the same longitudinal section as the top blade; the sensor component receives the magnetic signal generated by the magnetic element to detect the number and frequency of the magnetic element arranged on the top blade passing through the sensor component, and outputs a corresponding pulse signal, and the pulse signal is used to identify the type of the auger.

[0006] Through the technical solution of the embodiment of the present application, the magnetic component that generates the magnetic signal and the sensor component that receives the magnetic signal can form a complete identification device. When the auger rotates, the sensor component can output a pulse signal corresponding to the number and frequency of the magnetic element passing by by receiving the magnetic signal generated by the magnetic element in the magnetic component passing through the sensor. Therefore, the condition of the magnetic element set on the auger that is currently running can be known through the pulse signal, thereby inferring the model of the auger running in the spreader at this time.

[0007] In some possible implementations, the distribution of the magnetic elements corresponds to the type of auger.

[0008] In the above embodiment, the types of auger can be distinguished by setting magnetic elements with different distribution patterns, that is, each distribution pattern of magnetic elements can represent a type of auger, and the distribution of magnetic elements can be obtained through pulse signals to infer the type of auger.

[0009] In some examples, the distribution manner includes the number of magnetic elements, and the number of pulses in one cycle of the pulse signal is the same as the number of magnetic elements.

[0010] In the case of this example, different numbers of magnetic elements are provided on different types of augers. In the same cycle, the number of pulses corresponds to the number of magnetic elements one by one, so the types of augers can be distinguished by the number of magnetic elements.

[0011] In some examples, when the number of magnetic elements is greater than or equal to two, the distribution method includes the spacing distance of the magnetic element distribution, and the pulse spacing distance within one cycle of the pulse signal is related to the spacing distance of the magnetic element distribution.

[0012] In this example, when the number of magnetic elements is greater than or equal to two, magnetic elements with different spacing distances are set on different types of augers, and in the same cycle, the distribution intervals of the magnetic signal pulses detected by the sensor will be correspondingly differentiated. In this case, even if different types of augers have the same number of magnetic elements, they can be distinguished by the distribution intervals, providing a more diverse form of distinction for augers.

[0013] In some possible implementations, the magnetic element is disposed on the outer edge portion of the top blade.

[0014] In the above-mentioned embodiment, such distribution can form a continuous annular magnetic field. During the rotation of the auger, the sensor assembly can stably capture the periodic magnetic field changes, thereby improving the accuracy and stability of recognition.

[0015] In some possible implementations, the sensor component is a Hall sensor printed circuit board, a Hall sensor is disposed on the Hall sensor printed circuit board, and the magnetic element is a magnet.

[0016] In the above embodiment, the magnet can provide a strong and stable magnetic signal, and the Hall sensor has high sensitivity and anti-interference ability, and can monitor the magnetic signal in real time. In addition, other components can be arranged on the Hall sensing printed circuit board to process the sensed magnetic signal and generate a stable pulse signal to realize the judgment of the auger type.

[0017] In some possible implementations, the magnetic component is disposed on the top blade by embedding it in a reserved slot, or by fixing it mechanically.

[0018] In the above-mentioned embodiment, the reserved slots can protect the magnetic components from external damage and maintain the stability and effectiveness of the magnetic signal, while the mechanical fixing method can be adapted to other scenarios that facilitate maintenance and replacement, that is, the method of installing the magnetic components can be determined according to actual needs.

[0019] In a second aspect, a method for identifying the type of auger is provided. The method is applied to an auger type identification device comprising at least a magnetic component and a sensor component. The magnetic component comprises at least one magnetic element, which is disposed on the top blade of the auger and is used to generate a magnetic signal. The sensor component is disposed on the outer casing of the auger and is located on the same longitudinal section as the top blade and is used to receive the magnetic signal. The method comprises: when the auger rotates, a pulse signal corresponding to the number and frequency of the magnetic element passing through the sensor component is obtained, and the pulse signal is used to identify the type of the auger; and the pulse signal is transmitted to a terminal.

[0020] The sensor component outputs a pulse signal corresponding to the number and frequency of the magnetic element passing through, and transmits the pulse signal to the terminal. The operator can learn the distribution of the magnetic elements on the auger that is currently running based on the pulse signal, and thus infer the model of the auger that is currently running in the spreader.

[0021] In some possible implementations, the distribution of the magnetic elements corresponds to the type of auger.

[0022] In some examples, the distribution manner includes the number of magnetic elements, and the number of pulses in one cycle of the pulse signal is the same as the number of magnetic elements.

[0023] In some examples, when the number of magnetic elements is greater than or equal to two, the distribution method includes the spacing distance of the magnetic element distribution, and the pulse spacing distance within one cycle of the pulse signal is related to the spacing distance of the magnetic element distribution.

[0024] In some possible implementations, the magnetic element is disposed on the outer edge portion of the top blade.

[0025] In some possible implementations, the sensor component is a Hall sensor printed circuit board, a Hall sensor is disposed on the Hall sensor printed circuit board, and the magnetic element is a magnet.

[0026] In some possible implementations, the magnetic component is disposed on the top blade by embedding it in a reserved slot, or by fixing it mechanically.

[0027] For the effects not described in detail in the above second aspect, please refer to the relevant description in the first aspect and will not be repeated here.

[0028] According to a third aspect, a spreading device is provided, wherein the spreading device is provided with an auger-type identification device as in the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

As used in the specification and appended claims of the present application, the singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0039] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0040] The present application provides an auger identification device and method, which can be used to determine the auger type in a spreading device.

[0041] The technical solution in the present application will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0042] With the advancement of science and technology, the application of spreaders in modern agricultural technology has become an increasingly common choice. In the design of the spreader, the auger assembly is used to transmit the spreading material and is the core component for controlling the key parameter of the sowing amount. In order to adapt to different sowing needs, it is often necessary to select the appropriate type of auger according to different situations. At present, the work of replacing the auger mainly relies on manual operation, but manual replacement may make mistakes. For example, when an inappropriate auger is misused, this may seriously affect the sowing effect and cause economic losses.

[0043] In order to address this problem, the present application proposes an auger identification device and method. The device can identify different types of auger structures, thereby effectively avoiding losses caused by using inappropriate auger types and improving the accuracy of sowing.

[0044] Figure 1 It is a schematic diagram of a spreading device provided in an embodiment of the present application.

[0045] Figure 1 It is a schematic diagram of a spreading device 100 provided in an embodiment of the present application. The spreading device 100 mainly includes an inlet 110 , an auger assembly 120 and an outlet 130 .

[0046] When in use, seeds or other materials are put into the device through the feed port 110. Subsequently, these materials are transported through the auger assembly 120. The design of the auger assembly 120 ensures the uniformity and stability of the materials during the transportation process, and avoids blockage or damage of the materials. Finally, after being transported by the auger assembly 120, the materials are spread to the designated area at the discharge port 130, thereby achieving sowing.

[0047] Figure 2 It is a schematic diagram of an auger assembly provided in an embodiment of the present application.

[0048] Figure 2 for Figure 1 The cross-sectional view of the middle auger assembly 120, the auger assembly 120 is composed of an outer shell 121 and an internal auger 122, the outer shell 121 is approximately cylindrical, forming a cavity, and the auger 122 is arranged in the cavity to rotate to achieve the transfer and transportation of materials.

[0049] The core components of the auger 122 include two top blades 1221 and 1222, a spiral blade group 1223 and a rotating shaft 1224. The rotating shaft 1224 is placed in the cavity of the housing 121, located at the center of the cavity, and parallel to the housing 121, that is, the rotating shaft 1224 is parallel to the direction A-A'. The top blades 1221 and 1222 are arranged in parallel at both ends of the rotating shaft 1224 and are perpendicular to the extension direction A-A' of the rotating shaft 1224. The spiral blade group 1223 is arranged along the rotating shaft 1224, and is located between the top blades 1221 and 1222.

[0050] During the operation of the auger 122, the material starts from the top blade 1221, and is gradually pushed and transmitted to the top blade 1222 through the rotation of the spiral blade group 1223. That is, the top blades 1221 and 1222 are the starting and ending points of the auger transmission system, and the spiral blade group 1223 continuously drives the material forward during rotation. At the same time, the spiral design ensures that the material can be stably advanced along the spiral path during the conveying process. In addition, the material can be evenly distributed, avoiding uneven spreading or blockage caused by material accumulation.

[0051] Different types of augers meet various sowing requirements through their structural characteristics and design differences, which are mainly reflected in the distribution density of the spiral blade groups 1223 of the auger. These design differences enable each type of auger to adapt to different sowing amounts, thereby meeting the planting needs of various crops and the requirements of different operating conditions.

[0052] Through these differences, different types of augers can flexibly control the seeding rate. For example, for precision seeding, high-density spiral blades can be selected to ensure accurate and even distribution of materials. For large-scale operations, low-density spiral blades can be selected to improve operation efficiency and quickly complete large-scale seeding. Through this structural difference design, different types of augers can provide flexible seeding control, thereby improving seeding efficiency and accuracy.

[0053] In order to realize the recognition of different types of auger 122, the present application proposes an auger recognition device, specifically as follows Figures 3 to 7 shown. Figure 3 is a schematic diagram of an auger identification device provided in an embodiment of the present application installed on a spreading device, Figure 4 is a schematic diagram of a sensor assembly provided in an embodiment of the present application installed on a spreading device, Figure 5 It is a partial schematic diagram of an auger identification device provided in an embodiment of the present application installed on a spreading device.

[0054] Figure 3 Shown Figure 1 The front view of the spreader from A to A' direction, Figure 4 for Figure 1 Bottom view of the spreader, combined with Figures 3 to 5 The composition and position setting of an auger identification device 300 provided in the embodiment of the present application can be embodied. Specifically, the auger identification device 300 includes a sensor component 310 and a magnetic component 320 .

[0055] In some embodiments, in the auger assembly 120 , the auger identification device may be configured as follows: the sensor assembly 310 is disposed on the auger housing 121 to detect changes in magnetic signals; the magnetic assembly 320 is disposed on the auger 122 to provide a detectable magnetic signal for the sensor assembly 310 .

[0056] In some embodiments, the sensor assembly 310 and the magnetic assembly 320 are located on the same longitudinal plane.

[0057] In this case, the stability and accuracy of the induction can be guaranteed. During the rotation of the auger, the layout maintained on the same longitudinal section allows the changes in the magnetic field to be continuously and evenly sensed during each rotation, thus ensuring high-precision signal output and higher recognition accuracy.

[0058] In some examples, the magnetic assembly 320 is disposed on the top blade 1221 .

[0059] Since the top blade 1221 is the frontmost part of the auger 122 and can be away from the complex structure of the auger 122, when the magnetic component 320 is set on the top blade 1221, the sensor component 310 can collect clear magnetic field changes during the rotation process. In addition, the design difference of the top blade 1221 in different models of the auger is small, which is convenient for achieving the versatility of the device, and because its position is easy to access, the installation and maintenance of the magnetic component are also more convenient, which can reduce the use and maintenance costs.

[0060] In some examples, the magnetic assembly 320 may be installed by being embedded inside the top blade 1221 .

[0061] For example, a notch is provided on the upper or lower surface of the blade, or a notch is reserved on the side edge to embed and fix the magnetic element. This method can protect the magnetic element from external physical damage while maintaining the stability and effectiveness of the magnetic signal.

[0062] In other examples, the magnetic component 320 can be designed as an independent magnetic module, the magnetic component 320 is pre-installed in the module, and then the module is fixed to the top blade by mechanical means such as screws, snaps or welding. This method is convenient for quick replacement and maintenance, and is suitable for equipment scenarios that require frequent maintenance.

[0063] In some examples, the magnetic assembly 320 includes at least one magnetic element, that is, different types of augers may be provided with different numbers of magnetic elements.

[0064] When the auger 122 rotates, each magnetic element can be induced by the sensor assembly 310 when passing through the sensor assembly 310, generating an induced voltage, which is processed into a pulse signal by the sensor assembly 310, that is, each magnetic element corresponds to a pulse. Therefore, the number of magnetic elements included in the magnetic assembly 320 can be judged by the number of pulses in a cycle, thereby determining different types of auger.

[0065] In some examples, when the magnetic assembly 320 includes at least two magnetic elements, the spacing distances between the magnetic elements can be set differently, that is, different types of augers can be provided with magnetic elements with different spacing distances.

[0066] When the auger 122 rotates, even if the magnetic assembly 320 includes the same number of magnetic elements, the distances between the waveforms of the generated pulses in the same cycle will be different due to the different spacings between the magnetic elements. Therefore, the spacings between the magnetic elements in the magnetic assembly 320 can be determined by the distances between the pulses in the cycle, thereby determining different types of auger.

[0067] In some examples, the magnetic elements may be distributed on the outer edge portion around the center of the top blade 1221 .

[0068] In these examples, this distribution can form a continuous annular magnetic field. During the rotation of the auger, the sensor assembly 310 can stably capture the periodic magnetic field changes, thereby improving the accuracy and stability of recognition.

[0069] In some examples, the magnetic element in the magnetic assembly 320 is a magnetic steel, which can provide a strong and stable magnetic signal.

[0070] Figure 6 It is a schematic diagram of a sensor component provided in an embodiment of the present application.

[0071] In some examples, such as Figure 6 As shown, the sensor assembly 310 includes a Hall sensor printed circuit board 311 and a Hall sensor printed circuit board fixing cover 312. The Hall sensor printed circuit board 311 is provided with a Hall sensor, which has high sensitivity and anti-interference ability, and can detect the change of magnetic signals in real time and generate corresponding identification signals. In addition, in addition to the Hall sensor, related modules such as a filter circuit and a signal processing circuit can also be provided.

[0072] In some examples, the Hall sensor printed circuit board fixing cover 312 is integrally formed with the auger housing 121, or the Hall sensor printed circuit board fixing cover 312 is a separate module and fixed to the auger housing 121 by means of screws, snaps or welding.

[0073] Figure 7 Schematic diagram of the arrangement of magnetic elements on different types of augers provided in the embodiments of the present application, such as Figure 7 Shown are schematic diagrams of different types of augers with different magnetic components 320 .

[0074] The top blade 1221 includes a rotating shaft fixing portion and an outer edge portion, and the magnetic components 320 are all arranged on the outer edge portion of the top blade 1221.

[0075] In some embodiments, the magnetic assembly 320 includes at least one magnetic element. When the number of the magnetic elements is greater than or equal to two, different distribution intervals may be set.

[0076] By setting magnetic elements of different numbers and intervals, when the auger 122 rotates in the cavity of the housing 121, the magnetic elements on the top blades will also rotate around the fixed part of the rotating shaft along with the auger 122. Since the sensor assembly 310 is fixed on the housing 121 and is located on the same longitudinal section as the magnetic assembly 320, when the auger 122 rotates with the magnetic elements, the sensor assembly 310 fixed on the housing 121 can generate a corresponding voltage pulse signal when each magnetic element passes.

[0077] Specifically, the distribution of magnetic elements with different numbers and intervals will directly affect the output mode of the voltage pulse signal. According to these different settings, the sensor assembly 310 can determine the number and interval of magnetic elements set on the auger according to the number and interval of the received pulse signals.

[0078] For example, when the number of magnetic elements is large, the output frequency of the pulse signal will increase accordingly, and vice versa, when the number is small, the output frequency of the pulse signal will be low. At the same time, the smaller the distribution interval between the magnetic elements, the shorter the interval between the pulse signals will be.

[0079] Therefore, when one rotation of the auger 122 is regarded as one cycle, different models of auger 122 have different numbers and distribution intervals of magnetic elements, and the number and interval of pulses output in one cycle are also different. Different auger models can be identified based on the pulse images of different numbers and intervals.

[0080] In some examples, such as Figure 7 As shown in (a), on the first type of auger, the magnetic elements are respectively distributed at the outer edge of the top blade 1221, one at the twelve o'clock direction and one at the three o'clock direction; Figure 7 As shown in (b), on the second type of auger, the magnetic element is arranged at the twelve o'clock position on the outer edge of the top blade 1221; Figure 7 As shown in (c), on the third type of auger, the magnetic elements are respectively distributed at the outer edge of the top blade 1221, one at the twelve o'clock direction and one at the six o'clock direction.

[0081] Through the number and distribution of the above-mentioned different magnetic elements, the pulse signals received by the sensor assembly 310 on different types of augers are not only different in number, but also in the intervals of the pulse signals. Using this feature, the model of the augers can be accurately identified, and corresponding operations or adjustments can be performed according to the characteristics of the pulse signals, thereby realizing the identification and adaptation of different augers and avoiding the impact of manual installation errors.

[0082] by Figure 7 The three types of auger models and the settings of the magnetic components can produce three different pulse diagrams, such as Figure 8 shown.

[0083] Figure 8 It is a schematic diagram of a square wave pulse generated by an auger identification process provided in an embodiment of the present application.

[0084] In some embodiments, one rotation of the auger is regarded as one detection cycle.

[0085] In some examples, the cycle starts at twelve o'clock.

[0086] like Figure 8 The sub-figures (a), (b), and (c) of the square wave pulse schematic diagram correspond to Figure 7 Three types of auger models and the distribution of magnetic components.

[0087] Specifically, Figure 7 A first type of auger shown in (a), and Figure 7 In the third type of auger shown in (c), two magnetic elements are provided, so two detection pulses appear in one detection cycle; Figure 7In the second type of auger shown in (b), since a magnetic element is provided, only one detection pulse appears in one detection cycle, so that the second type of auger can be distinguished from the first and third types of auger according to the number of pulses.

[0088] On the other hand, due to Figure 7 In the first type of auger shown in (a), the magnetic elements are distributed at the twelve o'clock direction and the three o'clock direction, and Figure 7 In the third type of auger shown in (c), the magnetic elements are distributed at the twelve o'clock and six o'clock positions, and the time intervals between the pulses generated during the rotation are different. When displayed on the pulse graph, it is shown that the spacing between the pulses is different. Figure 8 As shown in (a), the two pulses are respectively distributed at the beginning and one quarter of the detection period; Figure 8 As shown in (c), the two pulses are respectively distributed at the beginning and half of the detection period. According to the interval between the pulses, it can be known that the distribution intervals of the magnetic elements are different, and the first type of auger and the third type of auger can be distinguished according to the interval between the pulses.

[0089] It can be understood that the number and distribution intervals of the above-mentioned magnetic elements are only examples, and different specific settings can be made according to needs in actual operations.

[0090] Fig. 9 It is a method flow chart of a method for identifying an auger provided in an embodiment of the present application.

[0091] The method 900 comprises the following steps:

[0092] 910, when the auger rotates, a pulse signal corresponding to the number and frequency of the magnetic element passing through the threading component is obtained, and the pulse signal is used to identify the type of the auger;

[0093] 920, transmitting the pulse signal to the terminal.

[0094] The steps of method 900 are described in detail below.

[0095] 910. When the auger rotates, a pulse signal corresponding to the number and frequency of the magnetic element passing through the feeling component is obtained, and the pulse signal is used to identify the type of the auger.

[0096] In some embodiments, the magnetic assembly includes at least one magnetic element. When the auger is operating, the top blade rotates with the rotation of the auger, and the magnetic elements distributed on the top blade rotate accordingly, inducing the sensor assembly to output a corresponding voltage waveform.

[0097] The voltage signal output by the sensor component is proportional to the strength of the magnetic field and also changes with the change of the magnetic field strength, that is, the voltage waveform can reflect the strength of the magnetic field.

[0098] For example, when the magnetic element is closer to the sensor assembly, the voltage waveform output by the sensor assembly will be larger; when the magnetic element moves away from the sensor assembly after passing through the sensor assembly, the voltage waveform output by the sensor assembly will decrease accordingly.

[0099] By sensing the rotational motion of the top blade and the movement of its magnetic element, the sensor assembly is able to output a voltage waveform proportional to the magnetic field strength, thereby enabling monitoring of the operating status of the auger.

[0100] In some embodiments, the distribution pattern of the magnetic elements corresponds to the type of the auger, that is, different auger types have different distribution patterns of the magnetic elements.

[0101] In some examples, the distribution of the magnetic elements includes the number of magnetic elements, that is, the magnetic assembly may include different numbers of magnetic elements on different types of augers.

[0102] In this case, the sensor assembly outputs a signal waveform having pulses matching the number of magnetic elements.

[0103] In some examples, when the number of magnetic elements is greater than or equal to two, the distribution of the magnetic elements includes distribution intervals between the magnetic elements, that is, the arrangement of the magnetic elements in different auger types may have different intervals.

[0104] Taking the case where there are two magnetic elements as an example, the angle between the positions of the two magnetic elements and the center of the circle can be set to 90°, or the angle between the positions of the two magnetic elements and the center of the circle can be set to 180°.

[0105] In this case, with the top blade rotating one circle as the period, in the voltage waveform output by the sensor component, the interval between two peaks in the same period is different. In the first setting, the interval between the two peaks is one quarter of a period; while in the second setting, the interval between the two peaks is one half of a period.

[0106] It is understandable that the angle between the position of the magnetic element and the center of the circle may also be other degrees, and the above angle is only for illustration.

[0107] In some embodiments, the sensor assembly includes a Hall sensor printed circuit board, which is provided with related modules such as a filter circuit and a signal processing circuit in addition to the Hall sensor.

[0108] In some implementations, the filter circuit can perform noise reduction processing on the voltage waveform to remove interference.

[0109] Through noise reduction processing, the influence of non-target signals such as environmental interference and system noise is removed, making the final output pulse waveform clearer and more stable.

[0110] In some embodiments, the signal processing circuit uses an amplifier to amplify the peak value of the voltage waveform to avoid signal distortion or being submerged by noise, thereby accurately conveying the working status of the auger.

[0111] In some embodiments, after being processed by the sensor assembly, the voltage waveform becomes a more stable pulse signal that can be used for counting.

[0112] In the above implementation, the pulse signal is more stable than a voltage waveform with noise and environmental interference, which facilitates operators to identify the quantity and interval.

[0113] 920, transmitting the pulse signal to the terminal.

[0114] In some embodiments, the pulse waveform processed by the sensor assembly is transmitted to a terminal device, which is not limited to a computer, a mobile phone, a tablet, and the like.

[0115] In some embodiments, the pulse waveform can be transmitted to the terminal device via wired or wireless communication (such as serial communication, Bluetooth, Wi-Fi, etc.).

[0116] The operator can check the waveform displayed on the terminal device to know the condition of the magnetic element set on the auger that is currently running, and thus infer the type of the auger that is currently running in the spreader.
