Description

Technical Field

[0002] Before the seeder is transported from the farmer's home / farm to the farmland for operation, its seed meter is usually in a static empty tray state. To ensure the smooth progress of the sowing operation, the seed meter should be filled with seeds before the sowing operation is implemented. Different farmland fields may have different operating conditions. For example, some fields require uninterrupted sowing, while others require intermittent sowing. However, the existing seeders do not have adaptive seed filling methods for different filling requirements, which may lead to seed shortages or farmers needing to replenish the fields that are lacking seeds after sowing. There is also no targeted treatment method for incorrect seed filling operations, which may easily lead to the problem of sowing the wrong seeds.

[0058] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0059] The embodiment of the present application provides a method for pre-filling 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 that the charging operating member 1 is in an operated state.

[0061] Specifically, the seed drill in this embodiment may be 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, wherein the seed filling operating member 1 may be a button or a knob button; preferably, in this embodiment, the seed filling operating member 1 is a button. After the operator operates the seed filling operating member 1 (for example, presses a button), the seed filling operating member 1 sends a corresponding signal to the processor 3, and the processor 3 can determine that the seed filling operating member 1 is in an operated state after receiving the above signal.

[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 of the charging operation member 1 sent by the charging operation member 1, the timing module 2 starts the timing function and accumulates the operation time of the charging operation member 1, which 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 charging mode to perform a partial seeding operation; or,

[0067] Step S10331: When the duration is longer than the third preset duration, the seeder 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 from when the charging operation member 1 is pressed to when it is released is less than the first preset duration), the processor 3 accumulates the number of times the charging operation member 1 is in the operated state when the charging operation member 1 is converted from the operated state to the non-operated state. In this embodiment, the accumulated number of times the charging operation member 1 is operated is consistent with the accumulated number of times the charging operation member 1 is in the operated state. If the above accumulated number is not less than two times, and is two and two adjacent times, the charging operation member 1 is in the non-operated state. When the interval between the operated states is less than the second preset time (e.g., 1s), that is, when the seed charging operating member 1 is operated no less than twice, the duration of each operation of the seed charging operating member 1 is less than the first preset time, and the interval between two adjacent operations of the seed charging operating member 1 is less than the second preset time, 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 sowing the wrong type of seeds 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 compares 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 head 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 the first preset duration. If the duration is longer than the first preset duration, the processor 3 compares the duration with the third preset duration. If the duration is longer than the third preset duration (such as 2s), the processor 3 controls the seeder to enter the full charge mode so as to completely fill the seed meter 4 to avoid the situation of lack of seeds at the head of the field during sowing. In this embodiment, the full charge mode is suitable for the situation where non-stop sowing is required at the head of the field under normal conditions.

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

[0072] Furthermore, the pre-seeding method may also include 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 connected to the seeding mechanism in communication. Before the seeding mechanism performs the seeding operation (or when performing the seeding operation), the processor 3 sends a corresponding signal to the processor 3. After the processor 3 receives the above signal, it can be determined that the seed drill has entered the seeding mode; on the contrary, if the processor 3 does not receive the above signal, it can be determined that the seed drill has not performed the seeding operation. Further, step S100 in this embodiment 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, determining that the seed filling operating member 1 is in a non-operating state;

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

[0078] Specifically, the seeder also includes a driving member (such as a motor) and a seed unloading mechanism. The processor 3 is connected to the driving member and the seed unloading mechanism in communication, and the seed metering device 4 is connected to the driving member in driving. 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, the processor 3 controls the driving member to drive the seed metering device 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 as to first unload the seeds already in the seed metering device 4 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 seeder 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 Compared 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 rotates at least one circle, and then 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. Further, 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, and the preset speed is a fixed value and is pre-stored in the processor 3.

[0081] Step S204: Control the seed metering device 4 to stop rotating and control 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 communicatively connected to the processor 3 and is used to broadcast voice messages. Specifically, after the processor 3 completes step S203 or step S204 (i.e., after the seed unloading operation is completed), the processor 3 controls the voice announcer to broadcast a voice message of "seed unloading completed" to remind the operator that the seed 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, determining that the seed charging operating member 1 is in a non-operating state;

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

[0087] Specifically, the seeder also includes a seed charging mechanism that is communicatively connected to the processor 3 and is used to charge the seed meter 4 with seeds. After the processor 3 controls the seeder to enter the follow-charging mode and determines that the seed charging 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 charging mechanism to perform the seed charging operation so as to charge the seeds in the grain tank into the seed meter 4.

[0088] Step S303: Determine 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 metering device 4 and the seed filling mechanism to cooperate in performing a charging operation is a fourth preset time, which is pre-stored in the processor 3 and can be retrieved when needed. After the seed drill enters the charging mode, the timing module 2 accumulates the time for the seed metering device 4 to rotate in the second preset direction, and calculates the accumulated time t s Compared 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 without interruption be t z , the above duration t z The preselected time is stored in the processor 3, then 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 metering device 4 rotates at a preset speed The duration required is consistent.

[0092] Step S304: Control the seed metering device 4 to stop rotating and control 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 the fourth preset time, so as to avoid the situation where the seed filling operation is disordered.

[0094] Furthermore, after the execution of 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 after the single charging operation is completed, the operator determines that the single charging operation needs to be continued according to actual needs, the operator can operate the seed charging operation member 1 again (i.e., press the button again), and after the processor 3 receives the signal sent by the seed charging operation member 1 again indicating that the seed charging operation member 1 is operated, it will execute steps S302 to S304 again. That is, the operator can determine the number of times to operate the seed charging operation member 1 according to actual needs until the seeds on the seed metering device 4 can meet the actual needs.

[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, wherein 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 duration of the seed filling operating member 1 being in the operated state, and 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: controlling 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 connected in communication, and the angle display module can be an angle digital display. When the operator operates the seed filling operation member 1, the timing module accumulates the operation time of the seed filling operation member 1. As the operation time of the seed filling operation member 1 increases, the operation time of the seed filling operation member 1 also increases in real time. The real-time increase in 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 to the duration t z 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 by the proportion between the two, and the rotation angle is the real-time rotation angle. Then the processor 3 controls the rotation angle to display the above-converted real-time rotation angle, so that the operator can determine the rotation angle of the seed metering device 4 in the charging mode according to the operation time of the seed charging operating part 1 when there is a need for charging.

[0101] Step S404: After the seeder enters the charging mode, the seed charging operating member 1 is in a non-operating state, the seed meter 4 rotates in the second preset direction, and the seed charging mechanism performs the seed charging 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: clearing the timing module 2.

[0105] Specifically, in this embodiment, there are multiple timing modules 2, the timing module 2 that accumulates the time when the seed filling operating member 1 is operated is the first timing module, and the timing module 2 that accumulates the rotation time of the seed metering device 4 is the second timing module. After step S403 is executed, the processor 3 controls the driving member to drive the seed metering device 4 to rotate in the second preset direction (such as clockwise), and the processor 3 also controls the seed filling mechanism to perform the seed filling operation. During the rotation of the seed metering device 4, the second timing module accumulates the rotation time of the seed metering device 4, and compares the accumulated time of the second timing module with the accumulated time of the first timing module. If the above two time lengths are consistent, it is determined that the current charging operation has been completed. After that, the processor 3 controls the seed metering device 4 to stop rotating, controls the seed filling mechanism to stop performing the seed filling operation, and clears the first timing module to clear the accumulated time of the seed filling operating member 1 in the current charging operation, so as to facilitate the next charging operation to proceed smoothly.

[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, determining that the seed charging operating member 1 is in a non-operating state;

[0108] Step S502: Control the seed metering device 4 to rotate in a second preset direction and control 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 that the seed metering device 4 is in a full state.

[0111] In this embodiment, the processor 3 stores a sixth preset time length, which can be retrieved when needed. After the seeder 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 Compared 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: Control the seed metering device 4 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0113] 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 the sixth preset time, so as to avoid wasting energy and seeds.

[0114] Furthermore, after the execution of 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 has been completed.

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

[0116] Step S601: after the seed drill enters the seed unloading mode and the seed charging operating element 1 is in a non-operating state, determining within a preset time interval that the seed charging operating element 1 is in an operated state again.

[0117] Specifically, a preset interval time (such as 2s) is pre-stored in the processor 3, which can be retrieved when needed. After step S201 is executed, if the operator operates the seeding operation member 1 again (i.e., presses the button again) within the preset interval time, the seeding operation member 1 sends a corresponding signal to the processor 3 again, and the processor 3 can determine that the seeding operation member 1 is in the state of being operated again after receiving the above signal.

[0118] Furthermore, after step S201 is completed, the voice announcer broadcasts a voice message to remind the operator to operate in time within the preset time interval, so that the operator can operate the seed filling operation member 1 in time within the preset time interval to smoothly complete the subsequent seed unloading operation. If the operator fails to operate the seed filling operation member 1 in time within the preset time interval, the seed drill 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 put the seed filling operating member 1 in a non-operating state, the operator releases the seed filling operating member 1, and the seed filling operating member 1 sends a signal that the seed filling operating member 1 is released to the processor 3 again. After receiving the above signal, the processor 3 can determine that the seed filling operating member 1 is in a non-operating state, and then the processor 3 executes steps S202-S204 again to unload the original seeds in the seed meter 4. The setting of steps S601-S602 in this embodiment can prevent the operator from accidentally entering the seed unloading mode due to misoperation by the operator, further improving the reliability and practicality of the pre-seeding method.

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

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

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

[0124] Further, after step S301 or step 501 is completed, the voice announcer broadcasts a voice message to remind the operator to operate in time within the preset time interval, so that the operator can operate the seed filling operation member 1 in time within the preset time interval to smoothly complete the subsequent on-the-spot charging operation or full-charging operation. If the operator does not operate the seed filling operation member 1 in time within the preset time interval, the seed drill exits the current on-the-spot charging mode or full-charging mode.

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

[0126] Specifically, after the operator operates the seed charging operating member 1 again to put the seed charging operating member 1 in a non-operating state, the operator releases the seed charging operating member 1, and the seed charging operating member 1 sends a signal that the seed charging operating member 1 is released to the processor 3 again. After receiving the above signal, the processor 3 can determine that the seed charging operating member 1 is in a non-operating state, and then the processor 3 executes steps S302-step S304 or steps S502-step S504 to complete the random charging operation or the full charging operation. The setting of steps S603-step S604 in this embodiment can prevent the operator from accidentally entering the random charging mode or the full charging mode due to misoperation by the operator.

[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 seeder 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 on-the-fly charging mode, the operator can determine the number of on-the-fly charging operations to be performed based on visual observation.

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

[0133] A mounting member is arranged outside 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 arranged on the mounting member along the radial direction of the seed metering device 4;

[0135] The angle scale bar is arranged 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 arranged at the top of the outer side of the shell of the seed metering device 4, and the central axis of the mounting shaft coincides with the rotational central axis of the seed metering device 4; the angle indicator can be a pointer, which is arranged on the mounting shaft and distributed along the radial direction of the seed metering device 4. When the seed metering device 4 rotates, the rotation angle of the seed metering device 4 is consistent with the rotation angle of the pointer; the angle scale bar is arranged around the outer peripheral side of the shell of the seed metering device 4. The operator can know the rotation angle of the seed metering device 4 by observing the scale number of the angle scale bar pointed to by the end of the pointer away from the mounting shaft, and can then assist in understanding the seed filling situation inside the seed metering device 4. In the follow-up charging mode, the operator can determine the number of follow-up charging operations to be performed according to the scale number of the angle scale bar pointed to by the end of the pointer away from the mounting shaft.
