Description

Technical Field

[0002] Before a seeder is deployed and transported from a farmer's home / farm to the field for operation, its seed meter is usually in a static, empty state. To ensure smooth seeding operations, the seed meter should be filled with seeds before the operation begins. Different fields may have different operating conditions. For example, some fields require continuous seeding, while others require intermittent seeding. Existing seeders do not have adaptive seed filling methods for different filling needs, which can easily lead to seed shortages or farmers needing to replenish the missing seeds in the fields after the seeder is sown. There are also no targeted solutions for incorrect seed filling operations, which can easily lead to the sowing of the wrong seeds. The above problems will affect crop yields or increase farmers' labor time and labor costs. Summary of the Invention

[0058] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0059] The embodiment of the present application provides a method for pre-filling seeds in a seed drill, such as Figure 1 As shown, the seeder includes a seed filling operating member 1, and the pre-seeding method includes the following steps:

[0060] Step S101: Determine whether the seed filling operating member 1 is in an operated state.

[0061] Specifically, the seed drill in this embodiment can be selected as a mechanical seed drill or an electric seed drill. Figure 2 As shown, the seed drill further includes a processor 3, which is in communication with a seed filling operating member 1. The seed filling operating member 1 can be a button or a knob; preferably, in this embodiment, the seed filling operating member 1 is a button. When an operator operates the seed filling operating member 1 (for example, by pressing a button), the seed filling operating member 1 sends a corresponding signal to the processor 3. Upon receiving the signal, the processor 3 determines that the seed filling operating member 1 is in an operated state.

[0062] Step S102: Obtain the duration of the operated state.

[0063] Specifically, a timing module 2 is provided in the processor 3. After the processor 3 receives the signal sent by the charging operation member 1, the timing module 2 starts the timing function and accumulates the time the charging operation member 1 is operated. The time is the duration of the operation state.

[0064] Step S10311: When the duration is less than the first preset duration, the number of times the charging operating member 1 is in the operated state is accumulated;

[0065] Step S10312: When the number of times is not less than two and the interval between two adjacent operation states is less than a second preset time, control the seeder to enter the unloading mode to perform the unloading operation; or

[0066] Step S10321: When the duration is longer than the first preset duration and shorter than the third preset duration, the seed drill is controlled to enter the on-the-fly charging mode to perform a partial seeding operation; or

[0067] Step S10331: When the duration is longer than the third preset duration, the seed drill is controlled to enter the full charging mode to perform all seed charging operations.

[0068] Specifically, the processor 3 pre-stores a first preset duration (such as 1s) and a second preset duration (such as 1s), which can be retrieved when needed. The processor 3 compares the duration of the operated state with the first preset duration. If the duration is less than the first preset duration (i.e., the total duration between the pressing and releasing of the seeding operation member 1 is less than the first preset duration), the processor 3 accumulates the number of times the seeding operation member 1 is in the operated state when the seeding operation member 1 is converted from the operated state to the non-operated state. In this embodiment, the cumulative number of times the seeding operation member 1 is operated is consistent with the cumulative number of times the seeding operation member 1 is in the operated state. If the above cumulative number is not less than two times, and is two and two adjacent times, The interval between the operated states is less than the second preset time length (such as 1s), that is, when the seed filling operation member 1 is operated at least twice, the duration of each operation of the seed filling operation member 1 is less than the first preset time length, and the interval between two adjacent operations of the seed filling operation member 1 is less than the second preset time length, the processor 3 controls the seeder to enter the seed unloading mode, so that when the type of seeds in the seed metering device 4 is inconsistent with the type of seeds to be sown, the original seeds in the seed metering device 4 are unloaded to avoid the situation where the wrong type of seeds are sown in the subsequent sowing process.

[0069] In another embodiment, the processor 3 compares the duration of the operation state with the first preset duration. If the duration is greater than the first preset duration, the processor 3 will then compare the duration with the third preset duration. If the duration is greater than the first preset duration and less than the third preset duration (such as 2s), the processor 3 controls the seeder to enter the charging mode, so that the operator can subsequently charge the seed meter 4 according to actual needs. The charging mode in this embodiment is suitable for situations where intermittent sowing is required at the edge of the field or where there are seeds to be sown in the seed meter 4.

[0070] In another embodiment, the processor 3 compares the duration of the operation state with a first preset duration. If the duration is longer than the first preset duration, the processor 3 then compares the duration with a third preset duration. If the duration is longer than the third preset duration (e.g., 2 seconds), the processor 3 controls the seeder to enter a full-charge mode to completely fill the seed meter 4 to avoid a shortage of seeds at the head of the field during sowing. In this embodiment, the full-charge mode is suitable for situations where continuous sowing is required at the head of the field under normal circumstances.

[0071] The pre-seeding method in this embodiment is simple and easy to operate. The seeder has a seed unloading mode, a charging mode and a full charging mode. The operator can control the duration of the operation of the seed charging operating part 1 according to the actual situation and work requirements, and then select the appropriate mode in a targeted manner. The operation is simple and flexible, and the number of hardware components required is small, which expands the scope of application of the seeder, is conducive to reducing the production and manufacturing cost of the seeder, is conducive to ensuring crop harvest, and is conducive to reducing farmers' labor time and labor costs.

[0072] Furthermore, the pre-seeding method may further comprise the following steps:

[0073] Step S100: Determine that the seed drill is not performing a seeding operation.

[0074] Specifically, the seed drill also includes a seeding mechanism, and the processor 3 is in communication with the seeding mechanism. Before (or during) the seeding operation, the seeding mechanism sends a corresponding signal to the processor 3. Upon receiving the signal, the processor 3 determines that the seed drill has entered the seeding mode. Conversely, if the processor 3 does not receive the signal, it determines that the seed drill has not yet started the seeding operation. Furthermore, in this embodiment, step S100 is executed before step S101.

[0075] In one embodiment of the present application, the seeder further includes a seed meter 4 and a seed unloading mechanism, and the pre-seeding method further includes the following steps:

[0076] Step S201: After the seeder enters the seed unloading mode, it is determined that the seed filling operating member 1 is in a non-operating state;

[0077] Step S202: controlling the seed metering device 4 to rotate toward a first preset direction and controlling the seed unloading mechanism to perform a seed unloading operation.

[0078] Specifically, the seeder also includes a drive (such as a motor) and a seed unloading mechanism. The processor 3 is in communication with the drive and the seed unloading mechanism, and the seed meter 4 is in driving connection with the drive. After the operator releases the seed filling operating member 1, the seed filling operating member 1 sends a corresponding signal to the processor 3. After receiving the above signal, the processor 3 can determine that the seed filling operating member 1 is in a non-operating state. Therefore, after the processor 3 controls the seeder to enter the seed unloading mode and determines that the seed filling operating member 1 is released, it controls the drive to drive the seed meter 4 to rotate in a first preset direction (such as counterclockwise). The processor 3 also controls the seed unloading mechanism to perform the seed unloading operation so that the seeds already in the seed meter 4 are first unloaded into the collection box.

[0079] Step S203: Determine that the seed metering device 4 is in an empty tray state.

[0080] Specifically, in this embodiment, the processor 3 pre-stores a fifth preset time length, which can be retrieved when needed. After the planter enters the seed unloading mode, the timing module 2 accumulates the time length of the seed meter 4 rotating in the first preset direction, and calculates the accumulated time length t x Comparing with the fifth preset time, if the above accumulated time t x When the fifth preset time is reached, it is determined that the seed metering device 4 has rotated at least one circle, and further, it can be determined that the seed metering device 4 is in an empty disk state at this time, wherein the fifth preset time is not less than the time required for the seed metering device 4 to rotate one circle. Furthermore, in this embodiment, the speed at which the seed metering device 4 rotates in each direction in various modes of the seeder is a preset speed, which is a fixed value and pre-stored in the processor 3.

[0081] Step S204: controlling the seed metering device 4 to stop rotating and controlling the seed unloading mechanism to stop performing the seed unloading operation.

[0082] Specifically, after determining that the seed metering device 4 is in an empty disc state, the processor 3 controls the seed metering device 4 to stop rotating and controls the seed unloading mechanism to stop performing the seed unloading operation, so as to avoid the seed metering device 4 idling for a long time and wasting energy.

[0083] In one embodiment of the present application, the seed drill also includes a voice announcer, which is communicated with the processor 3 and is used to broadcast voice messages. Specifically, after the processor 3 completes step S203 or step S204 (that is, after the unloading operation is completed), it controls the voice announcer to broadcast a voice message of "unloading is completed" to remind the operator that the unloading operation has been completed.

[0084] In one embodiment of the present application, the seeder further includes a seed meter 4 and a seed filling mechanism, and the pre-seeding method further includes the following steps:

[0085] Step S301: After the seed drill enters the charging mode, it is determined that the seed charging operating member 1 is in a non-operating state;

[0086] Step S302: controlling the seed metering device 4 to rotate toward a second preset direction and controlling the seed filling mechanism to perform a seed filling operation.

[0087] Specifically, the seeder also includes a seed filling mechanism that is communicated with the processor 3 and is used to fill the seed meter 4 with seeds. After controlling the seeder to enter the follow-filling mode and determining that the seed filling operating member 1 is released, the processor 3 controls the driving member to drive the seed meter 4 to rotate in a second preset direction (such as clockwise). The processor 3 also controls the seed filling mechanism to perform the seed filling operation so as to fill the seeds in the grain tank into the seed meter 4.

[0088] Step S303: determining that the rotation time of the seed metering device 4 reaches a fourth preset time, wherein the fourth preset time is less than the time required for the seed metering device 4 to rotate one circle without interruption.

[0089] Specifically, in this embodiment, the time required for the seed meter 4 and the seed filling mechanism to cooperate in performing a follow-up charging operation is a fourth preset time, which is pre-stored in the processor 3 and can be retrieved when needed. After the planter enters the follow-up charging mode, the timing module 2 accumulates the time the seed meter 4 rotates in the second preset direction and calculates the accumulated time t s Comparing with the fourth preset time, if the above accumulated time t s When the fourth preset time is reached, it is determined that the single charging operation is completed.

[0090] Furthermore, let the time required for the seed metering device 4 to rotate one circle at a preset speed be t z , the above duration t z The preselected time is stored in the processor 3, and the fourth preset time is Wherein, m is a positive integer.

[0091] In another embodiment, the angle of rotation of the seed meter 4 during a single filling operation is Wherein, k is a positive integer; the fourth preset time length and the seed meter 4 rotate at a preset speed The required duration is consistent.

[0092] Step S304: controlling the seed metering device 4 to stop rotating and controlling the seed filling mechanism to stop performing the seed filling operation.

[0093] Specifically, the processor 3 controls the seed metering device 4 to stop rotating and controls the seed filling mechanism to stop performing the seed filling operation after the rotation time of the seed metering device 4 reaches a fourth preset time, so as to avoid confusion in the seed filling operation.

[0094] Furthermore, after step S303 or step S304 is completed (ie, after the charging operation is completed), the processor 3 controls the voice announcer to broadcast a voice message of "charging operation completed" to remind the operator that the charging operation is completed.

[0095] Furthermore, if the operator determines that a further single-time charging operation is required after the single-time charging operation is completed, the operator can simply operate the seed charging operating element 1 again (i.e., press the button again). Upon receiving the signal from the seed charging operating element 1 indicating that the seed charging operating element 1 has been operated, the processor 3 will execute steps S302-S304 again. In other words, the operator can determine the number of times to operate the seed charging operating element 1 based on actual needs until the seeds on the seed meter 4 meet the actual demand.

[0096] In another embodiment of the present application, the seeder further includes a seed meter 4, an angle detection module, an angle display module, a timing module 2, and a seed filling mechanism. The angle detection module is used to determine the rotation angle of the seed meter 4 in real time according to the real-time duration of the operated state. The angle display module is used to display the rotation angle in real time. The timing module 2 is used to accumulate the time duration of the seed filling operation member 1 in the operated state. The pre-seeding method further includes the following steps:

[0097] Step S401: obtaining the real-time duration of the operated state;

[0098] Step S402: determining the rotation angle of the seed metering device 4 in real time according to the real-time duration;

[0099] Step S403: Control the angle display module to display the rotation angle in real time.

[0100] Specifically, the angle detection module, the angle display module, the timing module 2, the seed filling mechanism and the processor 3 are in communication connection. The angle display module can be an angle digital display. When the operator operates the seed filling operating member 1, the timing module accumulates the operation time of the seed filling operating member 1. As the operation time of the seed filling operating member 1 increases, the operation time of the seed filling operating member 1 also increases in real time. The real-time increase in the operation time is the real-time duration of the operation state. The timing module 2 sends the real-time duration to the processor 3, and the processor 3 then adds the real-time duration and the duration t z All are sent to the angle detection module, which detects the angle according to the real-time duration and duration t z The rotation angle of the seed metering device 4 corresponding to the real-time duration is converted based on the ratio between the two periods. The rotation angle is the real-time rotation angle. The processor 3 then controls the rotation angle to display the above-calculated real-time rotation angle, so that the operator can determine the rotation angle of the seed metering device 4 in the follow-up charging mode according to the operation time of the seed charging operating member 1 when there is a need for follow-up charging.

[0101] Step S404: After the seeder enters the charging mode, the seed filling operating member 1 is in a non-operating state, the seed meter 4 rotates toward the second preset direction, and the seed filling mechanism performs the seed filling operation,

[0102] Step S405: determining whether the rotation time of the seed metering device 4 reaches the continuous time;

[0103] Step S406: controlling the seed metering device 4 to stop rotating and controlling the seed filling mechanism to stop performing the seed filling operation;

[0104] Step S407: Reset the timing module 2.

[0105] Specifically, in this embodiment, there are multiple timing modules 2. The timing module 2 that accumulates the duration of operation of the seed filling operating member 1 is a first timing module, and the timing module 2 that accumulates the rotation duration of the seed meter 4 is a second timing module. After step S403 is executed, the processor 3 controls the driving member to drive the seed meter 4 to rotate in a second preset direction (e.g., clockwise). The processor 3 also controls the seed filling mechanism to perform the seed filling operation. During the rotation of the seed meter 4, the second timing module accumulates the duration of rotation of the seed meter 4 and compares the duration accumulated by the second timing module with the duration accumulated by the first timing module. If the two durations are consistent, it is determined that the current seed filling operation has been completed. The processor 3 then controls the seed meter 4 to stop rotating, controls the seed filling mechanism to stop performing the seed filling operation, and resets the first timing module to clear the accumulated duration of operation of the seed filling operating member 1 during the current seed filling operation, so as to facilitate the smooth execution of the next seed filling operation.

[0106] In one embodiment of the present application, the seeder further includes a seed meter 4 and a seed filling mechanism, and the pre-seeding method further includes the following steps:

[0107] Step S501: After the seed drill enters the full charging mode, it is determined that the seed charging operating member 1 is in a non-operating state;

[0108] Step S502: controlling the seed metering device 4 to rotate toward a second preset direction and controlling the seed filling mechanism to perform a seed filling operation.

[0109] Specifically, after controlling the seeder to enter the full filling mode and determining that the seed filling operating member 1 is released, the processor 3 controls the driving member to drive the seed meter 4 to rotate in a second preset direction (such as clockwise). The processor 3 also controls the seed filling mechanism to perform the seed filling operation so as to fill the seeds in the grain tank into the seed meter 4.

[0110] Step S503: Determine whether the seed metering device 4 is in a full state.

[0111] In this embodiment, the processor 3 pre-stores a sixth preset time length, which can be retrieved when needed. After the planter enters the full charging mode, the timing module 2 accumulates the time length of the seed meter 4 rotating in the second preset direction, and calculates the accumulated time length t q Comparing with the sixth preset time, if the above accumulated time t q When the sixth preset time is reached, it is determined that the seed metering device 4 has completed one rotation, and further it can be determined that the seed metering device 4 is in a full state at this time, wherein the sixth preset time is the time required for the seed metering device 4 to rotate one rotation at a preset speed without interruption.

[0112] Step S504: controlling the seed metering device 4 to stop rotating and controlling the seed filling mechanism to stop performing the seed filling operation.

[0113] Specifically, after the rotation time of the seed metering device 4 reaches a sixth preset time, the processor 3 controls the seed metering device 4 to stop rotating and controls the seed filling mechanism to stop performing the seed filling operation to avoid wasting energy and seeds.

[0114] Furthermore, after step S503 or step S504 is completed (ie, after the full charging operation is completed), the processor 3 controls the voice announcer to broadcast a voice message of "full charging operation completed" to remind the operator that the full charging operation is completed.

[0115] In one embodiment of the present application, the pre-seeding method further includes:

[0116] Step S601: after the seeder enters the seed unloading mode and the seed charging operating member 1 is in the non-operating state, it is determined within a preset time interval whether the seed charging operating member 1 is in the operated state again.

[0117] Specifically, a preset interval (e.g., 2 seconds) is pre-stored in the processor 3 and can be retrieved when needed. After step S201 is completed, if the operator operates the seeding operating element 1 again (i.e., presses the button again) within the preset interval, the seeding operating element 1 again sends a corresponding signal to the processor 3. Upon receiving the signal, the processor 3 determines that the seeding operating element 1 is in the operated state again.

[0118] Furthermore, after step S201 is completed, the voice announcer plays a voice message reminding the operator to promptly operate the seed filling operation member 1 within the preset time interval, so that the operator can promptly operate the seed filling operation member 1 within the preset time interval to smoothly complete the subsequent seed unloading operation. If the operator does not promptly operate the seed filling operation member 1 within the preset time interval, the seeder exits the current seed unloading mode.

[0119] Step S602: after determining that the seed filling operating member 1 is in a non-operating state, controlling the seed metering device 4 of the seeder to rotate in a first preset direction and controlling the seed unloading mechanism of the seeder to perform a seed unloading operation;

[0120] Specifically, after the operator operates the seed filling operating member 1 again to place it in the non-operating state, the operator releases the seed filling operating member 1, which again sends a release signal to the processor 3. Upon receiving the signal, the processor 3 determines that the seed filling operating member 1 is in the non-operating state, and then executes steps S202-S204 to remove the seeds originally in the seed meter 4. The configuration of steps S601-S602 in this embodiment prevents the seeder from accidentally entering the seed unloading mode due to operator error, further improving the reliability and practicality of the pre-seeding method.

[0121] In another embodiment of the present application, the pre-seeding method further includes:

[0122] Step S603: after the seed drill enters the seed charging mode and the seed charging operating member 1 is in the non-operating state, determining within a preset interval whether the seed charging operating member 1 of the seed drill is in the operated state again, wherein the seed charging mode is the random charging mode or the full charging mode;

[0123] Specifically, after step S301 or step 501 is completed, if the operator operates the seeding operation member 1 again (i.e., presses the button again) within a preset interval, the seeding operation member 1 again sends a corresponding signal to the processor 3. After receiving the above signal, the processor 3 can determine that the seeding operation member 1 is in the state of being operated again.

[0124] Furthermore, after step S301 or step 501 is completed, the voice announcer plays a voice message reminding the operator to promptly operate the seed filling operation member 1 within the preset time interval, so that the operator can promptly operate the seed filling operation member 1 within the preset time interval to smoothly complete the subsequent sequential charging operation or full charging operation. If the operator does not promptly operate the seed filling operation member 1 within the preset time interval, the seed drill exits the current sequential charging mode or full charging mode.

[0125] Step S604: After determining that the seed filling operating member 1 is in the non-operating state, the seed metering device 4 is controlled to rotate toward the second preset direction and the seed filling mechanism is controlled to perform the seed filling operation.

[0126] Specifically, the operator operates the seed filling operating member 1 again to place it in the non-operating state, then releases the seed filling operating member 1. The seed filling operating member 1 again sends a release signal to the processor 3. Upon receiving the signal, the processor 3 determines that the seed filling operating member 1 is in the non-operating state. The processor 3 then executes steps S302-S304 or steps S502-S504 to complete the follow-up charging operation or the full charging operation. The configuration of steps S603-S604 in this embodiment prevents the seeder from accidentally entering the follow-up charging mode or the full charging mode due to operator error.

[0127] Another embodiment of the present application provides a control device, comprising:

[0128] a memory configured to store instructions; and

[0129] The processor 3 is configured to call instructions from the memory and implement the pre-seeding method of the planter in the above embodiment when executing the instructions.

[0130] Another embodiment of the present application provides a seeder, which includes a seed filling operating member 1, a seed metering device 4 and the above-mentioned control device.

[0131] In one embodiment of the present application, the shell of the seed metering device 4 is made of a transparent material (such as acrylic material). Furthermore, the shell of the seed metering device 4 made of a transparent material makes it easy for the operator to observe the seed filling situation inside the seed metering device 4. In the charging mode, the operator can determine the number of charging operations to be performed based on visual observation.

[0132] In another embodiment of the present application, the seed drill further comprises:

[0133] The mounting member is arranged on the outside of the housing of the seed metering device 4 and coincides with the rotation center axis of the seed metering device 4;

[0134] An angle indicator is provided on the mounting member along the radial direction of the seed metering device 4;

[0135] The angle scale bar is provided on the housing and is used to cooperate with the angle indicator to detect the rotation angle of the seed metering device 4.

[0136] Specifically, the mounting member is a mounting shaft mounted on the top of the outer shell of the seed meter 4, with the central axis of the mounting shaft coinciding with the rotational axis of the seed meter 4. The angle indicator can be a pointer mounted on the mounting shaft and distributed radially along the seed meter 4. When the seed meter 4 rotates, the angle of rotation of the seed meter 4 and the angle of rotation of the pointer coincide. An angle scale bar is provided around the outer periphery of the shell of the seed meter 4. The operator can determine the rotation angle of the seed meter 4 by observing the number of graduations on the angle scale bar pointed by the end of the pointer away from the mounting shaft, thereby assisting in understanding the seed filling status within the seed meter 4. In the on-demand filling mode, the operator determines the number of on-demand filling operations to be performed based on the number of graduations on the angle scale bar pointed by the end of the pointer away from the mounting shaft.
