[0050] 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.

[0051] In an embodiment of the present application, a method for pre-charging a seed drill is provided. The seed drill comprises a seeding disc 1 and a seed charging mechanism. Figure 1-Figure 3 As shown, the pre-seeding method comprises the following steps:

[0052] Step S110: before the seeder performs an operation, it is determined that a manual full seed filling signal is received;

[0053] Step S111: within a first preset time period, controlling the seeding disc 1 to rotate in a first preset direction and controlling the seed filling mechanism to perform a seed filling operation, so that the seeding disc 1 is manually and completely filled with seeds; or,

[0054] Step S120: before the seeder performs an operation, determining that a manual local seed filling signal is received;

[0055] Step S121: in the process of receiving the manual partial seed filling signal, controlling the seeding disc 1 to rotate in a first preset direction and controlling the seed filling mechanism to perform the seed filling operation, so that the seeding disc 1 is manually partially seeded, wherein the cumulative duration of receiving the manual partial seed filling signal is less than the first preset duration; or,

[0056] Step S130: When the seeder starts to operate, it is determined that an automatic seed filling signal is received;

[0057] Step S131: within a second preset time period, the seed disc 1 is controlled to rotate in a first preset direction and the seed filling mechanism is controlled to perform a seed filling operation, so that the seed disc 1 is automatically and quickly filled with seeds.

[0058] Specifically, Figure 4As shown, the seeder also includes a human-machine interaction device 4 (such as a remote controller or a touch screen) and a processor 3. The processor 3 is communicatively connected with the human-machine interaction device 4 and the seed filling mechanism. The human-machine interaction device 4 is provided with a button for the operator to select a seed filling mode. For example, before the seeder performs an operation, the operator operates on the touch screen to select a manual seed filling mode (if the previous seed filling mode is an automatic seed filling mode, it is necessary to first switch the automatic seed filling mode to the manual seed filling mode), wherein the manual seed filling mode includes a manual full seed filling mode and a manual partial seed filling mode. After entering the manual seed filling mode page of the touch screen, the operator selects between the manual full seed filling mode and the manual partial seed filling mode based on actual needs (such as when the field to be operated needs to be sown without gaps, manual full seed filling can be selected, or when the field to be operated needs to be sown with gaps, manual partial seed filling can be selected).

[0059] If the operator selects the manual full seed filling mode, the human-computer interaction device 4 will send a manual full seed filling signal to the processor 3. After receiving the manual full seed filling signal, the processor 3 controls the seeding disc 1 to rotate in the first preset direction (such as counterclockwise), and controls the seed filling mechanism to perform the seed filling operation. In this embodiment, the time taken for the seeding disc 1 to be manually fully filled with seeds is the first preset time. After the seeding disc 1 is manually fully filled with seeds, the seeding disc 1 is in a full state. In this embodiment, the manual full seed filling mode is suitable for situations where gapless sowing is required in some special environments.

[0060] If the operator selects the manual local seed filling mode, the human-machine interaction device 4 will send a manual local seed filling signal to the processor 3. Furthermore, in this embodiment, after the operator selects the manual local seed filling mode, the human-machine interaction device 4 needs to continue to operate (such as continuously pressing the button corresponding to the manual local seed filling mode) so that the human-machine interaction device 4 continues to send the manual local seed filling signal to the processor 3. The processor 3 continues to receive the manual local seed filling signal and the cumulative time of receiving the manual local seed filling signal is less than the first preset time. Therefore, during the period when the processor 3 continues to receive the manual local seed filling signal, the seeding disc 1 is controlled to rotate in the first preset direction, and the seed filling mechanism is controlled to perform the seed filling operation. In this embodiment, the manual local seed filling mode is suitable for situations where gap sowing is required at the head of the field or there are seeds in the seeding disc 1 before manual local seed filling.

[0061] In one embodiment of the present application, the seed drill includes a power source and a traveling mechanism, and the automatic seed filling signal is a start signal of the power source or a traveling signal of the traveling mechanism.

[0062] Specifically, the power source and the traveling mechanism are both connected to the processor in communication, and the power source can be selected as an engine. In the automatic seed filling mode of the seeder (the default seed filling mode of the seeder in this embodiment is the seeder), if the operator forgets to operate and does not perform manual full seed filling or manual partial seed filling before the seeder operates (i.e. before the seeder starts and moves), in order to ensure the smooth progress of subsequent sowing operations (avoid leaving a gap for pre-filling the field), when the seeder starts to operate, the processor controls the seeder to execute steps S130-S131. If the automatic seed filling signal is selected as the start signal of the power source, the rotation speed of the engine of the seed drill changes suddenly, and the engine sends a rising edge mutation signal to the processor 3, and the rising edge mutation signal sent by the engine is the start signal of the engine. Further, the rising edge mutation signal sent by the engine is also the automatic seed filling signal; if the automatic seed filling signal is selected as the walking signal of the walking mechanism, the driving speed of the walking mechanism of the seed drill changes suddenly, and the walking mechanism sends a rising edge mutation signal to the processor 3, and the rising edge mutation signal sent by the walking mechanism is the walking signal of the walking mechanism. Further, the rising edge mutation signal sent by the walking mechanism is also the automatic seed filling signal. After receiving the automatic seed filling signal, the processor 3 controls the seeding disc 1 to rotate in the first preset direction, and at the same time controls the seed filling mechanism to perform the seed filling operation. After the seeding disc 1 is automatically filled with seeds, the seeding disc 1 is in a full state. In this embodiment, the time taken for the seeding disc 1 to be automatically filled with seeds is the second preset time, which is less than the first preset time. Therefore, compared with the manual full seeding mode, the seeding disc 1 can be filled faster in the automatic seeding mode to avoid the situation of lack of seeds at the head of the field. In this embodiment, the automatic seeding mode can be directly applied to the situation where the head of the field needs to be sown without gaps under normal conditions, but the main purpose of setting the automatic seeding mode is to prevent the operator from forgetting to operate and failing to perform manual full seeding or manual partial seeding, resulting in the phenomenon of no sowing at the head of the field.

[0063] The pre-seeding method in this embodiment is simple and easy to operate, and the seed filling method is flexible, so that the seed tray 1 can be manually fully filled, manually partially filled or automatically filled. The operator can select the appropriate seed filling method according to the actual situation and operation requirements, which expands the application scope of the seeder, is beneficial to ensuring crop harvest, and is beneficial to reducing farmers' labor time and labor costs.

[0064] Furthermore, since the automatic seed filling is performed before the seed drill is started and moves, the automatic seed filling is limited to "fast" pre-seed filling, so as not to affect the subsequent seeding after the seed drill moves; in the actual application process, as a person skilled in the art, it should be understood that the "fast" here means that the time of automatic seed filling is as short as possible, and of course it is preferred that it can be done without affecting the normal sowing after the subsequent seed drill moves (no gap is left at the end of the field). A specific scheme in this embodiment is that the first preset time is at least twice the second preset time (that is, the rotation speed of the seeding disc 1 during automatic seed filling is at least twice the rotation speed of the seeding disc 1 during manual full seed filling); the seed drill also includes a drive motor 5 that is connected to the processor 3 and is used to drive the seeding disc 1 to rotate, and the driving end of the drive motor 5 is provided with a driving gear, and the seeding disc 1 is provided with a driven gear meshing with the driving gear, and the drive motor 5 drives the seeding disc 1 through the driving gear and the driven gear. In addition, a reduction assembly is also provided inside the drive motor 5 to increase the torque output range of the drive motor 5, which is conducive to realizing high-speed seed filling of the seeding disc 1.

[0065] In one embodiment of the present application, the seeder further includes a seed unloading mechanism, and the pre-seeding method further includes the following steps:

[0066] Step S201: after receiving the manual full seed filling signal and before controlling the seeding disc 1 to rotate in the first preset direction, controlling the seeding disc 1 to rotate in the second preset direction and controlling the seeding mechanism to perform the seeding operation; or,

[0067] Step S202: after receiving the automatic seed filling signal and before controlling the seeding disc 1 to rotate in the first preset direction, controlling the seeding disc 1 to rotate in the second preset direction and controlling the seed unloading mechanism to perform the seed unloading operation.

[0068] Specifically, the seed unloading mechanism is connected to the processor 3 for communication and is used to unload seeds from the seeding disc 1. Before the seeding disc 1 is completely filled with seeds manually or automatically, if there are still seeds in its filling area, it will cause seed waste (because when a seed enters the filling area where there are seeds before, the original seeds in the filling area will fall from the filling area to the ground). Therefore, in order to avoid the above situation, after receiving the manual complete filling signal or the automatic filling signal, the processor 3 first controls the seeding disc 1 to rotate in the second preset direction (such as clockwise) and controls the seed unloading mechanism to perform the seed unloading operation, so as to unload the existing seeds on the seeding disc 1 into the collection box first. After the seed unloading mechanism completes the seed unloading, the processor 3 controls the seeding disc 1 to rotate in the first preset direction and controls the seed filling mechanism to perform the seed filling operation.

[0069] In one embodiment of the present application, the pre-seeding method further includes the following steps:

[0070] Step S301: in the process of the seeding disc 1 being manually fully filled with seeds, obtaining a first accumulated time length of the seeding disc 1 rotating in a first preset direction;

[0071] Step S302: Determine whether the first accumulated duration reaches a first preset duration;

[0072] Step S303: Determine whether the seeding tray 1 is full;

[0073] Step S304: Control the seeding disc 1 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0074] Specifically, the seeder also includes a timing module 2. After the processor 3 receives a manual complete seed filling signal, the seed disc 1 rotates in a first preset direction, and the seed filling mechanism performs a seed filling operation, the processor 3 controls the timing module 2 to start accumulating timing to obtain a first accumulated time length. The first accumulated time length is the accumulated time length of the seed disc 1 rotating in the first preset direction in the manual complete seed filling mode. Then, the first accumulated time length is compared with the first preset time length. If the first accumulated time length is greater than or equal to the first preset time length, it is determined that the seed disc 1 is in a full state, that is, the manual complete seed filling is completed. On this basis, the seed disc 1 is controlled to stop rotating and the seed filling mechanism is controlled to stop the seed filling operation. Through the above method, the in-place locking function of the seed disc 1 in the manual complete seed filling mode can be realized. The in-place identification method is simple, and no additional components need to be set, which is conducive to reducing production costs and avoiding energy and seed waste. Among them, the first preset time length is pre-stored in the processor 3 and can be retrieved when needed.

[0075] Furthermore, in the manual full seed charging mode, the rotation speed of the drive motor 5 is determined according to the following method:

[0076]

[0077] Among them, V1 is the rotation speed of the driving motor 5 in the manual full seed filling mode; n1 is the rotation speed ratio of the driving motor 5 and the seed disc 1 in the manual full seed filling mode; t1 is the first preset time.

[0078] In the manual full seed filling mode in the embodiment of the present application, the rotational speed of the seed disc 1 when rotating in the first preset direction is consistent with the rotational speed of the seed disc 1 when rotating in the second preset direction, that is, in the manual full seed filling mode, the time taken by the seed filling mechanism to perform the seed filling operation is consistent with the time taken by the seed unloading mechanism to perform the seed unloading operation.

[0079] In one embodiment of the present application, the pre-seeding method further includes the following steps:

[0080] Step S401: in the process of the seeding disc 1 being automatically filled with seeds, obtaining a second accumulated time length of the seeding disc 1 rotating in the first preset direction;

[0081] Step S402: Determine whether the second accumulated duration reaches a second preset duration;

[0082] Step S403: Determine whether the seeding tray 1 is full;

[0083] Step S404: Control the seeding disc 1 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0084] Specifically, after the processor 3 receives the automatic seed filling signal, the seed disc 1 rotates in the first preset direction and the seed filling mechanism performs the seed filling operation, the processor 3 controls the timing module 2 to start accumulating timing to obtain a second accumulated time length, which is the accumulated time length of the seed disc 1 rotating in the first preset direction in the automatic seed filling mode. Thereafter, the second accumulated time length is compared with the second preset time length. If the second accumulated time length is greater than or equal to the second preset time length, it is determined that the seed disc 1 is in a full state, that is, the automatic seed filling is completed. On this basis, the seed disc 1 is controlled to stop rotating and the seed filling mechanism is controlled to stop the seed filling operation. Through the above method, the in-place locking function of the seed disc 1 in the automatic seed filling mode can be realized. The in-place identification method is simple, and no additional components need to be set, which is conducive to reducing production costs and avoiding waste of energy and seeds. Among them, the second preset time length is pre-stored in the processor 3 and can be retrieved when needed.

[0085] Furthermore, in the automatic seed filling mode, the rotation speed of the driving motor 5 is determined according to the following method:

[0086]

[0087] Among them, V2 is the rotation speed of the driving motor 5 in the automatic seed filling mode; n2 is the rotation speed ratio of the driving motor 5 and the seed disc 1 in the automatic seed filling mode; t2 is the second preset time length.

[0088] In the automatic seed filling mode in the embodiment of the present application, the rotational speed of the seed disc 1 when rotating in the first preset direction is consistent with the rotational speed of the seed disc 1 when rotating in the second preset direction, that is, in the automatic seed filling mode, the time taken by the seed filling mechanism to perform the seed filling operation is consistent with the time taken by the seed unloading mechanism to perform the seed unloading operation.

[0089] In one embodiment of the present application, the pre-seeding method further includes the following steps:

[0090] Step S501: after receiving a manual partial seed filling signal, the seeding disc 1 rotates in a first preset direction, and the seed filling mechanism performs a seed filling operation, determining that the manual partial seed filling signal is lost;

[0091] Step S502: Control the seeding disc 1 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0092] Specifically, in the manual partial seed filling mode, the operator needs to continuously operate the human-computer interaction device 4 (such as continuously pressing the button corresponding to the manual partial seed filling mode) to maintain the continuous movement of the seed disc 1 and the seed filling mechanism. Therefore, if the operator cancels the operation on the human-computer interaction device 4 (such as releasing the button corresponding to the manual partial seed filling mode) after receiving the manual partial seed filling signal, the seed disc 1 rotates in the first preset direction, and the seed filling mechanism performs the seed filling operation, the manual partial seed filling of the seed disc 1 will also stop.

[0093] In one embodiment of the present application, the pre-seeding method further includes the following steps:

[0094] Step S601: after receiving a manual local seed filling signal, controlling the seeder to enter a local seed filling mode;

[0095] Step S602: When the seeder enters the local seed filling mode and continues to receive the manual local seed filling signal, the seeding disc 1 is controlled to rotate in a first preset direction and the seed filling mechanism is controlled to perform the seed filling operation;

[0096] Step S603: Obtain the total duration of the manual local seeding signal being received in the local seeding mode;

[0097] Step S604: When the manual partial seeding signal is not lost, determining that the total duration reaches a first preset duration;

[0098] Step S605: Control the seeding disc 1 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0099] Specifically, after receiving the manual local seed filling signal, the processor 3 immediately controls the seed drill to enter the local seed filling mode, and accumulates the duration of receiving the manual local seed filling signal in the local seed filling mode (i.e., the duration of the operator pressing the button corresponding to the manual local seed filling mode in the local seed filling mode is accumulated). For example, after the seed drill enters the local seed filling mode, if the processor 3 continuously and uninterruptedly receives the manual local seed filling signal (i.e., the operator presses the button corresponding to the manual local seed filling mode only once), the timing module 2 accumulates the duration of receiving the manual local seed filling signal to obtain the total duration t of receiving the manual local seed filling signal. j , and the total duration t j Compared with the first preset time t1, if the total time t of receiving the manual local seeding signal is j The first preset time t1 (i.e., t j<t1), and the processor 3 continues to receive the manual partial seeding signal (i.e., the operator has not released the button corresponding to the manual partial seeding mode at this time), then the seed metering disc 1 continues to rotate and the seeding mechanism continues to perform the seeding operation; if the total duration t of receiving this manual partial seeding signal j reaches the first preset duration t1 (i.e., t j ≥t1), and the processor 3 still continues to receive the manual partial seeding signal (i.e., the operator has not released the button corresponding to the manual partial seeding mode at this time), then the processor 3 controls the seed metering disc 1 to stop rotating and controls the seeding mechanism to stop performing the seeding operation while the above total duration t j reaches the first preset duration t1.

[0100] After the seeder enters the partial seeding mode, if the processor 3 receives the manual partial seeding signal multiple times (i.e., the operator presses the button corresponding to the manual partial seeding mode multiple times), the duration of receiving the manual partial seeding signal each time is accumulated, and the sum of the accumulated durations of receiving the manual partial seeding signal multiple times from the first time of receiving the manual partial seeding signal until the current moment is calculated, and this sum is the total duration t of the manual partial seeding signal received in the partial seeding mode j , if the total duration t of receiving this manual partial seeding signal j does not reach the first preset duration t1 (i.e., t j <t1), and the processor 3 still continues to receive the manual partial seeding signal (i.e., the operator has not released the button corresponding to the manual partial seeding mode at this time), then the seed metering disc 1 continues to rotate and the seeding mechanism continues to perform the seeding operation; if the total duration t of receiving this manual partial seeding signal j reaches the first preset duration t1 (i.e., t j ≥t1), and the processor 3 still receives the manual partial seeding signal at this time (i.e., the operator has not released the button corresponding to the manual partial seeding mode at this time), then the processor 3 controls the seed metering disc 1 to stop rotating and controls the seeding mechanism to stop performing the seeding operation while the above total duration t j reaches the first preset duration t1. Through the above method, the in-place locking function of the seed metering disc 1 in the manual partial seeding mode can be realized. The in-place recognition method is simple, no additional components need to be set, which is beneficial to reducing the production and manufacturing cost and avoiding waste of energy and seeds.

[0101] In an embodiment of the present application, the seeder further includes a seeding mechanism and a timing module 2, and the pre-seeding method further includes the following steps:

[0102] Step S701: After the seed metering disc 1 is manually partially seeded and the seeding mechanism performs the seeding operation, it is detected that the seed metering disc 1 is in an empty disc state;

[0103] Step S702: clearing the timing module 2.

[0104] Specifically, the sowing mechanism is connected to the processor 3 for communication and is used to sow the seeds on the seed tray 1 into the farmland. The seeder also includes an empty tray detector 6 connected to the processor 3 for communication and is used to detect whether the seed tray 1 is in an empty tray state. The empty tray detector 6 can be optionally an infrared sensor. The infrared sensor can be arranged on the seed drop tube and located at the middle or upper position of the seed drop tube, or can be arranged at a position close to the seed drop opening in the seed tray 1. After the seed tray 1 is manually partially filled with seeds and the sowing mechanism performs the sowing operation, the processor 3 controls the empty tray detector 6 to turn on the empty tray detection function and sends the detection result to the processor 3. If the processor 3 determines that the seed tray 1 is empty based on the above detection result, the timing module 2 is reset to zero, so as to reset the accumulated time of the timing module 2 during the partial seed filling (i.e., to reset the accumulated time of receiving the manual partial seed filling signal), so that the next round of seed filling operation can be carried out smoothly.
