[0043] 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.

[0044] The embodiment of the present application provides a seed filling method of a seeding machine, wherein the seeding machine comprises a seeding disc 2, a driving member 1 and a seed filling mechanism, wherein the seeding disc 2 is drivingly connected to the driving member 1, and the seed filling mechanism is used to fill the seeding disc 2 with seeds, such as Figure 2 As shown, the charging method comprises the following steps:

[0045] Step S101: Determine that the seed drill is not performing a seeding operation.

[0046] Specifically, the seeder in this embodiment can be selected as a mechanical seeder, which also includes a sowing mechanism and a processor. The processor is communicatively connected with the sowing mechanism, the seed filling mechanism, and the driving member 1. Before the sowing mechanism implements the sowing operation (or when implementing the sowing operation), it will send a corresponding signal to the processor. After the processor receives the above signal, it can be determined that the seeder has entered the sowing mode; on the contrary, if the processor does not receive the above signal, it can be determined that the seeder has not implemented the sowing operation.

[0047] Step S102: Determine whether the driving member 1 is powered on and the accumulated time in the powered state reaches a first preset time.

[0048] Furthermore, the driving member 1 in this embodiment may be selected as a driving motor, and the seeder also includes a power supply 3 (in this embodiment, the power supply 3 may be selected as a vehicle-mounted battery of the seeder), a first connecting wiring harness, a second connecting wiring harness, a third connecting wiring harness and a switch 4, the first end of the first connecting wiring harness is electrically connected to the positive pole of the power supply 3, the second end of the first connecting wiring harness is electrically connected to the first connecting end of the switch 4, the first end of the second connecting wiring harness is electrically connected to the second connecting end of the switch 4, the second end of the second connecting wiring harness is connected to the positive pole of the driving member 1, the first end of the third connecting wiring harness is electrically connected to the negative pole of the driving member 1, and the second end of the third connecting wiring harness is electrically connected to the negative pole of the power supply 3. The switch 4 can be selected as a button or a knob. In the present embodiment, the switch 4 is preferably selected as a button, which is a self-resetting normally open button. When no external force is applied, the contact is disconnected. In this case, the electrical connection between the power supply 3 and the drive member 1 is in a disconnected state, and the drive member 1 is not powered at this time. When the button is pressed to maintain the effect, the contact is closed. In this case, the electrical connection between the power supply 3 and the drive member 1 is in a conductive state, and the drive member 1 is powered at this time.

[0049] In this embodiment, after the driving component 1 is powered on, a corresponding signal is sent to the processor. After the processor receives the above signal, it can determine that the driving component 1 is powered on; or, the button is communicated with the processor, and after the button is pressed, a corresponding signal is sent to the processor. After the processor receives the above signal, it can determine that the button is pressed, and then determine that the driving component 1 is powered on.

[0050] The processor is equipped with a timing module, such as Figure 1 As shown, after the processor determines that the driver 1 is powered on, the timing module starts to accumulate timing to obtain the cumulative time that the driver 1 is in the powered state (the time is the time that the button is pressed continuously), and compares the above time with the first preset time t1 (such as 1s). If the above time is greater than or equal to the first preset time t1, it is determined that the cumulative time that the driver 1 is in the powered state reaches the first preset time t1, wherein the first preset time t1 is pre-stored in the processor and can be called out when needed.

[0051] Step S103: controlling the driving member 1 to drive the seed disc 2 to rotate in a first preset direction.

[0052] Specifically, when the accumulated time that the driving member 1 is in the powered state reaches the first preset time t1, the processor controls the driving member 1 to drive the seed disc 2 to rotate in a first preset direction. In this embodiment, the first preset direction is counterclockwise.

[0053] Step S104: Control the seed filling mechanism to perform the seed filling operation.

[0054] Specifically, step S103 and step S104 can be performed successively or simultaneously. In this embodiment, preferably, step S104 and step S104 are performed simultaneously, and when the accumulated time length of the driving member 1 in the powered state reaches the first preset time length t1, the processor controls the seed filling mechanism to perform the seed filling operation so as to fill the seeds in the seed box onto the seeding disc 2.

[0055] Step S10510: Determine that the accumulated time that the driving member 1 is in the powered state reaches a second preset time t2, control the driving member 1 to stop driving the seeding disc 2 to rotate, and the seeder completes the full seed charging operation.

[0056] Specifically, after the seed disc 2 rotates and the seed charging mechanism performs the seed charging operation, the timing module is still accumulating timing. At this time, the accumulated time that the driving member 1 is in the powered state is compared with the second preset time t2 (such as 2s). If the above time is greater than or equal to the second preset time t2, it is determined that the accumulated time that the driving member 1 is in the powered state reaches the second preset time t2, wherein the second preset time t2 is pre-stored in the processor and can be retrieved when needed. In this embodiment, the second preset time t2 is greater than the first preset time t1.

[0057] When the accumulated time of the driving member 1 in the energized state reaches the second preset time t2, the seeding disc 2 rotates a full circle, and during the process of the seeding disc 2 rotating a full circle, the seed filling mechanism performs the seed filling operation. After the seeding disc 2 rotates a full circle, all the seed filling areas on the seeding disc 2 are filled with seeds, that is, the seeding disc 2 is completely filled with seeds. In order to avoid wasting energy and seeds, after the seeding disc 2 is completely filled with seeds, the processor controls the driving member 1 to stop driving the seeding disc 2, the seeding disc 2 stops rotating, and the processor controls the seed filling mechanism to stop the seed filling operation. The complete seed filling operation in this embodiment is applicable to the situation where the seeding disc 2 is completely empty and there is no gap in sowing at the head of the field under normal conditions.

[0058] In another embodiment of the present application, after the processor completes step S104, the processor performs the following steps:

[0059] Step S10520: Determine that after the cumulative time when the driving member 1 is in the energized state reaches the third preset time, the driving member 1 loses power, and the seeder completes the partial seed filling operation and the seed disc 2 is partially filled with seeds when the driving member 1 loses power, wherein the third preset time is greater than the first preset time t1 and less than the second preset time t2.

[0060] Specifically, after the seed charging mechanism performs the seed charging operation, the processor determines that the driving member 1 has lost power, and the cumulative time that the driving member 1 is in the energized state before losing power is greater than the first preset time t1 and less than the second preset time t2. After the driving member 1 loses power, the drive to the seed disc 2 is stopped, and the seed disc 2 stops rotating. At the same time, the processor controls the seed charging mechanism to stop the seed charging operation. After the seed disc 2 and the seed charging mechanism stop moving, only a part of the seed charging areas on the seed disc 2 are charged with seeds in the above process, and the local seed charging operation is completed.

[0061] The operator can operate the buttons according to actual needs to choose to partially fill the seed tray 2 with seeds. The operation is simple and improves the flexibility of the seeder. The partial seed filling mode is suitable for situations where the seed tray 2 is not empty, the geographical environment is special, and there is a gap for sowing at the edge of the field.

[0062] The seed filling method is simple and easy to operate, and the seed filling mode is flexible, so that the seed tray can be fully or partially filled with seeds. The operator can select the appropriate seed filling mode according to the actual situation and operation requirements, thereby expanding the application scope of the seeder, which is beneficial to ensuring crop harvest and reducing farmers' labor time and labor costs.

[0063] In one embodiment of the present application, the seed drill further includes a seed unloading mechanism for unloading seeds in the seed tray 2, and the seed unloading mechanism is communicatively connected to the processor.

[0064] In one embodiment of the present application, the seed filling method further comprises:

[0065] Before the seeder performs the sowing operation, the seeder is controlled to enter the seed unloading mode so that the seed tray 2 is in an empty tray state;

[0066] After the seeding disc 2 is in an empty disc state, it is determined that the driving member 1 is powered on and the accumulated time in the powered state reaches a first preset time;

[0067] Control the driving member 1 to drive the seeding disc 2 to rotate in a first preset direction;

[0068] Controlling the seed filling mechanism to perform the seed filling operation;

[0069] It is determined that the accumulated time length of the driving member 1 being in the energized state reaches a second preset time length, and the driving member 1 is controlled to stop driving the seeding disc 2 to rotate, and the seeder completes the full seeding operation.

[0070] Specifically, if the seeding disc 2 is fully filled with seeds when there are still seeds in the seeding area, it will cause seed waste (because when a seed enters the seeding area where there are seeds before, the original seeds in the seeding area will fall from the seeding area to the ground). Therefore, to avoid this situation, if the operator observes that there are still seeds in the seeding area of ​​the seeding disc 2, before the seeder performs the full seeding operation, the seeder will first enter the seeding mode and perform the seeding operation on the seeds on the seeding disc 2, so as to first unload the seeds on the seeding disc 2 into the collection box. After the seeder does not perform the sowing operation and the seeding mechanism completes the seeding, the control step returns to step S102, and the seeding disc 2 is fully filled with seeds after being unloaded through steps S102-S10510.

[0071] In one embodiment of the present application, the seed filling method further comprises the following steps:

[0072] Step S201: after determining that the seed drill is not performing a seeding operation, determining that the driving member 1 is powered on and loses power within a first preset time after being powered on;

[0073] Step S202: Obtain the cumulative number of times the driving member 1 loses power after being powered on;

[0074] Step S203: Determine that the cumulative number of times is not less than two, and the interval between two adjacent power-on states is less than a preset interval;

[0075] Step S204: Control the seeder to enter a seed unloading mode.

[0076] Specifically, Figure 1 As shown, the operator presses the button first and then releases the button, then the driver 1 will be powered on and then powered off. The timing module sends the accumulated power-on time of the driver 1 to the processor after the driver 1 loses power. The processor then compares the above time with the first preset time t1 (such as 1s). If the above time is less than the first preset time t1, it is determined that the driver 1 loses power within the first preset time t1 after being powered on.

[0077] The processor accumulates the number of times that the driving member 1 loses power within the first preset time t1 after being powered on and the interval between two adjacent powered-on states is less than the preset interval time (such as 1s), and compares the above number with the preset number (such as 2 times). If the above number is greater than or equal to the preset number, it is determined that the accumulated number reaches the preset number, and then it is determined that the seeding disc 2 needs to be unloaded. The processor controls the seeder to enter the seed unloading mode, wherein the preset number and the preset interval time are pre-stored in the processor and can be retrieved when needed. Through the above seed charging method, the operator only needs to perform multiple intermittent button operations on the switch 4 according to the actual situation to make the seeder enter the seed unloading mode so that the seeds on the subsequent seeding disc 2 can be unloaded. In addition, the setting of steps S201-step S204 can also prevent the seeder from accidentally entering the seed unloading mode due to misoperation by the operator.

[0078] In an embodiment of the present application, step S201-step S204 is a seed unloading logic, and the processor executes step S201-step S204 once, that is, executes the seed unloading logic once. After the processor executes the seed unloading logic 2n times, the seed disc 2 is in a seed filling state; after executing the seed unloading logic 2n+1 times, the seed disc 2 is in a seed unloading state, where n is a natural number.

[0079] In one embodiment of the present application, the seed filling method further comprises the following steps:

[0080] Step S301: after the seeder enters the seed unloading mode, the seeding disc 2 is controlled to rotate in a second preset direction;

[0081] Step S302: controlling the seed unloading mechanism to perform the seed unloading operation;

[0082] Step S303: Determine whether the seed unloading mechanism has completed seed unloading;

[0083] Step S304: Control the seeding disc 2 to stop rotating and control the seed unloading mechanism to stop performing the seed unloading operation.

[0084] Specifically, step S301 can be executed after step S204. After determining that the seeder enters the seed unloading mode, the processor controls the driving member 1 to drive the seeding disc 2 to rotate in the second preset direction. The second preset direction in this embodiment is clockwise. In this embodiment, preferably, controlling the seeding disc 2 to rotate in the second preset direction and controlling the seed unloading mechanism to perform the seed unloading operation are performed simultaneously. When the seeding disc 2 rotates one circle in the second preset direction, it can be determined that the seed unloading mechanism has completed the seed unloading operation, and the seeds on the seeding disc 2 are unloaded into the collection box. After that, the processor controls the seeding disc 2 to stop rotating and controls the seed unloading mechanism to stop performing the seed unloading operation, so as to cause energy waste.

[0085] In one embodiment of the present application, the second preset time length is the time length required for the driving member 1 to drive the seed disc 2 to rotate one circle at a preset speed.

[0086] In one embodiment of the present application, the seed drill further comprises a sprocket mechanism 5 for transmitting power between the driving member 1 and the seeding disc 2, and the preset speed is determined according to the following method:

[0087]

[0088] Where r is the speed of the driving member 1; t m It is the time for the driving member 1 to rotate the seed disc 2 one circle when the driving member 1 is energized; 1 / ρ1 is the speed ratio between the first coaxial gear on the driving member 1 and the gear at the input end of the sprocket mechanism 5; 1 / ρ2 is the speed ratio between the gear at the input end of the sprocket mechanism 5 and the gear at the output end of the sprocket mechanism 5; 1 / ρ3 is the speed ratio between the gear at the output end of the sprocket mechanism 5 and the second coaxial gear on the seed disc 2.

[0089] Specifically, Figure 3 As shown, the seed drill also includes a mounting seat and a sprocket mechanism 5 for transmitting power between the driving member and the seeding disk 2. The mounting seat is detachably mounted on the main beam of the seed drill and is used to detachably mount the driving member. The mounting seat is mounted on the main beam of the seed drill through a half-beam buckle to facilitate the disassembly of the mounting seat; the driving member is connected to the driving member through bolts and spring washers. A first coaxial gear is provided at the output end of the driving member, and a second coaxial gear is provided on the seeding disk 2. The input end of the sprocket mechanism 5 is connected to the first coaxial gear, and the output end of the sprocket mechanism 5 is connected to the second coaxial gear. Further, in order to simplify the relationship between the rotation speed of the driving member and the rotation speed of the seeding disk 2, the speed ratio between the gears is 1 or an even value to eliminate conversion errors and improve calculation accuracy.

[0090] In one embodiment of the present application, the drive member may be a brushed motor (or other types of motors), which is helpful in reducing the overall cost of the seed drill. Furthermore, in the present embodiment, the drive motor and the processor are integrated, and the speed of the drive motor is equal to the number of revolutions of the drive motor shaft in the time consumed by the seeding disc 2 to rotate one circle.

[0091] Furthermore, the drive motor also includes a rotary encoder for detecting the rotational position of the drive motor. The rotary encoder, the drive motor and the processor can all be designed as an integrated structure to improve the sealing performance and have the advantages of dustproof and waterproof. The rotary encoder can feed back the actual position signal of the drive motor detected by it to the processor. The processor can achieve precise control of the position of the drive motor by comparing the theoretical position of the drive motor with the actual position of the drive motor, thereby ensuring the rotation accuracy of the seed disc 2.

[0092] Specifically, the processor sends a speed command to the drive motor, and the drive motor rotates according to the speed command. The rotary encoder sends the actual position to the processor during the rotation of the drive motor. The processor then compares the actual position of the drive motor with the theoretical position of the drive motor. When the actual positions of the drive motor are consistent, the processor sends a stop rotation signal to the drive motor, and the drive motor stops rotating after receiving the stop rotation signal.

[0094] Another embodiment of the present application provides a control device, which includes the processor in the above embodiment.

[0095] Another embodiment of the present application provides a seed drill, which includes the control device in the above embodiment.
