[0002] Before a seeder is transported from a farmer's home or farm to the field for operation, its seed tray is usually in a static, empty state.

[0050] 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.

[0051] In an embodiment of the present application, a method for pre-filling a seeding machine is provided. The seeding machine includes a seeding disc 1 and a seed filling mechanism. Figure 1-Figure 3 As shown, the pre-seeding method includes 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 seed disc 1 to rotate in a first preset direction and controlling the seed filling mechanism to perform a seed filling operation, so that the seed disc 1 is manually and completely filled with seeds; or

[0054] Step S120: Before the seeder performs an operation, it is determined that a manual partial seed filling signal is received;

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

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

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

[0058] Specifically, if Figure 4As shown, the seeder also includes a human-computer interaction device 4 (such as a remote control or a touch screen) and a processor 3. The processor 3 is communicatively connected to the human-computer interaction device 4 and the seed filling mechanism. The human-computer 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 to the manual seed filling mode). 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 (for example, when the end of the field to be operated needs to be sown without gaps, manual full seeding can be selected, or when the end of the field to be operated needs to be sown with gaps, manual partial seeding 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 seed disc 1 to rotate in a first preset direction (e.g., counterclockwise) and controls the seed filling mechanism to perform the seed filling operation. In this embodiment, the time it takes for the seed disc 1 to be manually fully filled with seeds is the first preset time. After the seed disc 1 is manually fully filled with seeds, the seed disc 1 is in a full state. In this embodiment, the manual full seed filling mode is suitable for situations where seamless seeding is required in some special environments.

[0060] If the operator selects the manual partial seed filling mode, the human-computer interaction device 4 will send a manual partial seed filling signal to the processor 3. Furthermore, in this embodiment, after the operator selects 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) so that the human-computer interaction device 4 continues to send the manual partial seed filling signal to the processor 3. The processor 3 continues to receive the manual partial seed filling signal, and the cumulative duration of receiving the manual partial seed filling signal is less than a first preset duration. Therefore, while the processor 3 continues to receive the manual partial seed filling signal, it controls the seed disc 1 to rotate in the first preset direction and controls the seed filling mechanism to perform the seed filling operation. In this embodiment, the manual partial seed filling mode is suitable for situations where intermittent seeding is required at the edge of the field or when there are seeds in the seed disc 1 before manual partial 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 communicatively connected to the processor, and the power source can be optionally an engine. In the automatic seed filling mode of the seeder (the default seed filling mode of the seeder in this embodiment), if the operator forgets to perform manual full seed filling or manual partial seed filling before the seeder operates (i.e., before the seeder starts and moves), then in order to ensure the smooth progress of subsequent sowing operations (to avoid leaving a gap at the head of the field for pre-filling), when the seeder starts operating, the processor controls the seeder to execute steps S130-S131. If the automatic seed filling signal is selected as the power source start signal, the seed drill's engine speed suddenly changes, and the engine sends a rising edge mutation signal to processor 3. This rising edge mutation signal sent by the engine is the engine start signal and, 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 travel signal of the walking mechanism, the travel speed of the seed drill's walking mechanism suddenly changes, and the walking mechanism sends a rising edge mutation signal to processor 3. This rising edge mutation signal sent by the walking mechanism is the travel signal of the walking mechanism and, further, the rising edge mutation signal sent by the walking mechanism is also the automatic seed filling signal. Upon receiving the automatic seed filling signal, processor 3 controls the seeding disc 1 to rotate in a first predetermined direction and simultaneously controls the seeding 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 it takes for the seed tray 1 to be automatically filled with seeds is a second preset time, which is less than the first preset time. Therefore, compared with the manual full filling mode, the seed tray 1 can be filled more quickly in the automatic filling mode to avoid the situation where there is a lack of seeds at the head of the field. In this embodiment, the automatic filling mode can be directly applied to situations where seamless seeding is required at the head of the field under conventional conditions. However, the main purpose of setting the automatic filling mode is to prevent the operator from forgetting to operate and failing to manually fill the field with seeds completely or manually partially, resulting in the phenomenon of not 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 range of the seeder, is conducive to ensuring crop harvest, and is conducive to reducing farmers' labor time and labor costs.

[0064] Furthermore, since automatic seed filling is performed before the seeder is started and moves, automatic seed filling is defined as a "fast" pre-seed filling, which does not affect the subsequent sowing of the seeder after it moves. In actual application, those skilled in the art should understand that "fast" here means that the automatic seed filling time is as short as possible, and of course it is preferred that it can be done without affecting the normal sowing of the subsequent seeder after it moves (leaving no gap at the edge of the field). A specific solution in this embodiment is that the first preset time length is at least twice the second preset time length (i.e., the rotation speed of the seed disc 1 during automatic seed filling is at least twice the rotation speed of the seed disc 1 during manual full seed filling). The seeder also includes a drive motor 5 that is communicatively connected to the processor 3 and is used to drive the seed disc 1 to rotate. The drive end of the drive motor 5 is provided with a driving gear, and the seed disc 1 is provided with a driven gear that meshes with the driving gear. The drive motor 5 drives the seed 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 achieving high-speed seed filling of the seed 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 seed disc 1 to rotate in the first preset direction, controlling the seed disc 1 to rotate in the second preset direction and controlling the seed unloading mechanism to perform the seed unloading operation; or,

[0067] Step S202: After receiving the automatic seed filling signal and before controlling the seed disc 1 to rotate in the first preset direction, controlling the seed 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 and is used to unload seeds from the seed tray 1. Before the seed tray 1 is completely filled 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 already seeds, the original seeds in the filling area will fall from the filling area to the ground). Therefore, to avoid the above situation, after receiving the manual complete seed filling signal or the automatic seed filling signal, the processor 3 first controls the seed tray 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 first unload the seeds already on the seed tray 1 into the collection box. After the seed unloading mechanism completes the seed unloading, the processor 3 controls the seed tray 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: while the seed disc 1 is being manually fully filled with seeds, obtaining a first accumulated time duration of the seed 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 seed tray 1 is full;

[0073] Step S304: Control the seed 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 the manual full 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 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 full seed filling mode. The above-mentioned first accumulated time length is then 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 full 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 full seed filling mode can be realized. The in-place identification method is simple, and no additional components are required, which is conducive to reducing production costs and avoiding waste of energy and seeds. 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 filling mode, the rotation speed of the drive motor 5 is determined according to the following method:

[0076]

[0077] Wherein, 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 to the seed disc 1 in the manual full seed filling mode; and 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: during the process of the seed disc 1 being automatically filled with seeds, obtaining a second accumulated time length of the seed 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 seed tray 1 is full;

[0083] Step S404: Control the seed 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. The second accumulated time length is the accumulated time length of the seed disc 1 rotating in the first preset direction in the automatic seed filling mode. The above second accumulated time length is then 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 are required, 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 drive 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 to 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 seed disc 1 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0092] Specifically, since 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, if 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 operator cancels the operation on the human-computer interaction device 4 (such as releasing the button corresponding to the manual partial seed filling mode), 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 the manual partial seed filling signal, control the seeder to enter the partial seed filling mode;

[0095] Step S602: When the seeder enters the partial seed filling mode and continues to receive the manual partial seed filling signal, the seed 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 seed disc 1 to stop rotating and control the seed filling mechanism to stop performing the seed filling operation.

[0099] Specifically, after receiving the manual partial seed filling signal, the processor 3 immediately controls the seed drill to enter the partial seed filling mode, and accumulates the time duration of receiving the manual partial seed filling signal in the partial seed filling mode (i.e., the time duration during which the operator presses the button corresponding to the manual partial seed filling mode in the partial seed filling mode is accumulated). For example, after the seed drill enters the partial seed filling mode, if the processor 3 continuously and uninterruptedly receives the manual partial seed filling signal (i.e., the operator presses the button corresponding to the manual partial seed filling mode only once), the timing module 2 accumulates the time duration of receiving the manual partial seed filling signal to obtain the total time duration t during which the manual partial seed filling signal is received. 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 (ie t j<t1),且处理器3还继续收到手动局部充种信号(即此时操作人员还未松开与手动局部充种模式相对应的按键),则排种盘1继续旋转、充种机构继续执行充种操作;若收到该手动局部充种信号的总时长t j Reaching the first preset time t1 (ie t j ≥t1), and at this time the processor 3 continues to receive the manual partial seed filling signal (that is, the operator has not released the key corresponding to the manual partial seed filling mode at this time), then the processor 3 will continue to receive the manual partial seed filling signal at this time (that is, the operator has not released the key corresponding to the manual partial seed filling mode at this time), and the processor 3 will continue to receive the manual partial seed filling signal at this time (that is, the operator has not released the key corresponding to the manual partial seed filling mode at this time), j When the first preset time t1 is reached, the seed disc 1 is controlled to stop rotating and the seed filling mechanism is controlled to stop performing the seed filling operation.

[0100] After the seed drill enters the partial seed filling mode, if the processor 3 receives the manual partial seed filling signal multiple times (i.e., the operator presses the button corresponding to the manual partial seed filling mode multiple times), the duration of each receipt of the manual partial seed filling signal is accumulated, and the total cumulative duration of the multiple receipts of the manual partial seed filling signal from the first receipt of the manual partial seed filling signal to the current moment is calculated. This total duration is the total duration t that the manual partial seed filling signal is received in the partial seed filling mode. j If the total time t of receiving the manual local seeding signal j The first preset time t1 (ie t j <t1),且处理器3还继续收到手动局部充种信号(即此时操作人员还未松开与手动局部充种模式相对应的按键),则排种盘1继续旋转、充种机构继续执行充种操作;若收到该手动局部充种信号的总时长t j Reaching the first preset time t1 (ie t j ≥t1), and at this time the processor 3 still receives the manual partial seed filling signal (that is, the operator has not released the key corresponding to the manual partial seed filling mode at this time), then the processor 3 j When the first preset time t1 is reached, the seed disc 1 is controlled to stop rotating and the seed filling mechanism is controlled to stop performing the seed filling operation. In this way, the in-position locking function of the seed disc 1 in the manual partial seed filling mode can be realized. The in-position identification method is simple and does not require the installation of additional components, which is conducive to reducing production costs and avoiding energy and seed waste.

[0101] In one embodiment of the present application, the seed drill 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 tray 1 is partially filled with seeds manually and the sowing mechanism performs the sowing operation, it is detected that the seed tray 1 is in an empty tray state;

[0103] Step S702: Reset 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 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 set on the seed drop tube and located in the middle or upper position of the seed drop tube, or can be set near the seed drop port 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 filling (that is, to reset the accumulated time of receiving the manual partial filling signal) so that the next round of filling operation can proceed smoothly.

[0105] In an embodiment of the present application, after the seed tray 1 is automatically filled with seeds (or manually fully filled with seeds) and the sowing mechanism performs the sowing operation, if the processor 3 determines that the seed tray 1 is in an empty tray state based on the detection result of the empty tray detector 6, it controls the human-computer interaction device 4 to send a reminder signal (such as displaying that the seed tray 1 is in an empty tray state in text or image) to remind the operator to perform subsequent operations to fill the seed tray 1 with seeds.

[0106] Another embodiment of the present application provides a control device, comprising:

[0107] a memory configured to store instructions; and

[0108] 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.
