[0002] With the continuous development of agricultural machinery, seeders have gradually replaced manual sowing. Mechanical seeders are equipped with a seeding device. When the seeder is moving, the seeding wheel in the seeding device rotates to sow seeds. The movement of the seeder requires power drive, and the rotation of the seeding wheel also requires power drive. If two independent drive mechanisms are set on the seeder, the structure is relatively redundant, so the movement of the seeder is linked with the seeding action of the seeding device. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a linkage seeder and a sowing method thereof, which links the traveling action of the seeder with the sowing action of the seeding device, so that only one set of driving mechanism is used on the seeder.

The two sprockets are driven by a chain, and the sprockets on the rear wheel shaft and the seed metering shaft are replaceable to change the transmission ratio between the rear wheel shaft and the seed metering shaft.

[0012] Further, the transmission mechanism is a transmission, and the rear wheel shaft and the seed metering shaft are connected by the transmission; a controller, a direction sensor, and a slope detector are also provided on the seeder.

[0019] Att Figure 3 is a schematic structural diagram of the rear roller and the frame. Detailed Embodiments

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] As attached Figures 1 to 3 The linkage seeder includes a frame 1, on which a seed meter 2 is arranged. A front axle 3 and a rear axle 4 are arranged at the front and rear of the frame 1, respectively, and a front roller 5 and a rear roller 6 are respectively installed on the front axle 3 and the rear axle 4. The front roller 5 and the rear roller 6 are both drum-shaped pressing wheels, and when the seeder is working, the front roller 5 and the rear roller 6 can flatten the soil.

[0022] A seeding shaft 7 is provided in the middle of the frame 1, and a seeding device 2 is installed in the middle of the frame 1, and a seeding wheel is provided in the seeding device 2. Sockets are provided on the wheel surface of the seeding wheel, and the seeds in the seeding device 2 fall into the sockets under the action of gravity. When the seeding wheel rotates, the seeds in the sockets are discharged to achieve sowing. The seeding wheel is correspondingly installed on the seeding shaft 7, and the seeding shaft 7 drives the seeding wheel to rotate. The rear wheel shaft 4 is connected to the seeding shaft 7 through a transmission mechanism 16, and when the rear roller 6 rolls, the transmission mechanism 16 drives the seeding wheel to rotate and sow seeds. Therefore, there is no need to set an additional power mechanism on the seeding shaft 7.

[0023] The front roller 5 is a driving wheel, and the rear roller 6 is a driven wheel. When the seeder is performing sowing operations, the front roller 5 actively rotates to drive the seeder forward, and the forward movement of the seeder drives the rear roller 6 to roll, and the rear roller 6 rolls and drives the seeding wheel to rotate and sow seeds through the transmission mechanism 16. Specifically, as shown in the attached figure Figure 2 As shown in the figure, a motor 11 is arranged inside the front roller 5. In addition, the frame 1 forms a support frame 12 above the front roller 5, and a battery box 13 for supplying power to the motor 11 is arranged on the support frame 12.

[0024] The rear part of the seed drill is provided with a push handle 14, which is connected to the frame 1. The operator can control the traveling direction of the seed drill by the push handle 14. When the battery box 13 is insufficiently powered, the operator can also push the seed drill forward by the push handle 14.

[0025] The push handle 14 is provided with a speed regulator 15, which can control the output power of the battery box 13, and further control the start and stop and the rotation speed of the motor 11. The speed regulator 15 can adjust the travel gear of the sowing machine and change the travel speed of the sowing machine.

[0026] A handle 17 is provided below the push handle 14. The handle 17 extends towards the rear of the seeder. When an upward force is applied to the handle 17, the rear part of the seeder can be lifted upwards. During the process of turning around the seeder, the seed metering device 2 cannot be allowed to discharge seeds. Therefore, the operator needs to lift the rear part of the seeder upwards through the handle 17 to suspend the rear roller 6 of the seeder. Thus, when the seeder turns around, the rear roller 6 will not rotate. Correspondingly, the seed metering shaft 7 will not rotate, and the seed metering device 2 will not discharge seeds.

[0027] As shown in the Figure 3 accompanying drawings, a parking port 8 is provided on one side of the rear roller 6, and a socket 9 is provided on the frame 1. The socket 9 is opposite to the parking port 8. When the parking pin 10 is inserted into the socket 9 and the parking port 8, it hinders the rotation of the rear roller 6, enabling the seeder to stop on a slope.

[0028] In one embodiment, the transmission mechanism 16 includes sprockets installed at the ends of the rear wheel shaft 4 and the seed metering shaft 7. The two sprockets are driven by a chain, and the sprockets on the rear wheel shaft 4 and the seed metering shaft 7 are replaceable to change the transmission ratio between the rear wheel shaft 4 and the seed metering shaft 7. When sowing different seeds, different spacing requirements for sowing are needed. At this time, the sprockets on the rear wheel shaft 4 and the seed metering shaft 7 can be replaced to change the sowing spacing. A tensioning mechanism is also provided within the transmission mechanism 16. After replacing the sprockets, the tensioning mechanism can tension the chain.

[0029] In another embodiment, the transmission mechanism 16 is a transmission. The rear wheel shaft 4 and the seed metering shaft 7 are connected through the transmission. The transmission can adjust the transmission ratio between the rear wheel shaft 4 and the seed metering shaft 7. A controller, a direction sensor, and a slope detector are also provided on the seeder. The direction sensor, such as an electronic compass, can detect the traveling direction of the seeder. The slope detector measures the inclination angle of the seeder relative to the horizontal through an accelerometer or a gyroscope to detect the slope along the traveling direction of the seeder. The controller can receive the detection information from the direction sensor and the slope detector, and adjust the gear position of the transmission according to the received detection information to change the transmission ratio between the rear wheel shaft 4 and the seed metering shaft 7, thereby changing the seed metering spacing of the seed metering device 2.

[0030] Light is an important factor affecting the growth of crops. The sun exposure degrees of different slopes are different. Therefore, when crops are planted on different slopes, the sunlight conditions received by the crops will also vary. In addition, when the crops grow to a certain height, the sunlight will be blocked between adjacent crops, and the degree of sunlight blockage will also be related to the slope of the slope. In summary, on slopes with different gradients and aspects, due to different sunlight conditions, the amount of solar radiation received by the crops is different, so the most suitable planting intervals for the crops are different. Correspondingly, the seed metering spacing of the seeder also needs to be adjusted adaptively.

[0031] In order to determine the sunshine conditions of the slope where the seeder is located, it is necessary to know the longitude and latitude of the geographical location where the slope is located, and it is also necessary to know the natural slope direction and natural slope of the slope. It should be noted here that the slope along the traveling direction of the seeder and the natural slope of the slope are two different concepts. The natural slope of the slope refers to the inclination angle in the steepest direction of the slope. Obviously, the seeder does not necessarily travel along the steepest direction of the slope during sowing. Therefore, it is necessary to convert the measured traveling direction of the seeder and the slope along the traveling direction of the seeder in order to obtain the natural slope direction and natural slope of the slope where the seeder is located. Then, combined with the longitude and latitude of the slope, the sunshine conditions of the slope can be obtained.

[0032] In summary, the present invention provides a seeding method for a linkage seeder. When the seeder sows in a certain area, first obtain the longitude and latitude information of the area where the seeder is located. In practical applications, a touch display screen is installed on the controller. Before using the seeder, the user operates on the touch display screen to select the city where they are located, and then the controller obtains the longitude and latitude information of the area where the seeder is located according to the selected city, thus facilitating the user's operation.

[0033] Then, when the seeder sows on a slope, the traveling direction of the seeder is detected by a direction sensor, and the slope along the traveling direction of the seeder is detected by a slope detector; combined with the traveling direction of the seeder and the slope along the traveling direction of the seeder, the natural slope direction and natural slope of the slope are obtained after conversion, and then combined with the longitude and latitude information of the area where the seeder is located, the sunshine conditions of the slope where the seeder is located are judged. Then, based on the sunshine conditions of the slope where the seeder is located, the gear of the transmission is adjusted so that the seeding spacing of the seeder is related to the sunshine conditions of the slope where the seeder is located.

[0034] Specifically, it includes the following process steps:

[0035] Step S1: Based on the gear of the transmission, divide the seeding spacing of the seeder into a reference spacing, a narrow first-level spacing, a narrow second-level spacing... that gradually becomes narrower compared to the reference spacing, and a wide first-level spacing, a wide second-level spacing... that gradually becomes wider compared to the reference spacing;

[0036] Step S2: Determine the area where the seeder is used and obtain the longitude and latitude information of the used area;

[0037] Step S3: According to the longitude and latitude of the used area, determine the reference slope corresponding to the reference spacing, and determine the reference slope direction and reference slope of the reference slope; for example, the reference slope direction is due north and the reference slope is 10 degrees; as the longitude and latitude of the area change, the sunshine conditions will change, and the reference slope direction can be kept unchanged while adjusting the size of the reference slope.

[0038] Step S4: When the seeder sows, use the direction sensor and slope detector to detect the traveling direction of the seeder and the slope along the traveling direction of the seeder, and then convert to obtain the natural slope direction and natural slope of the slope surface;

[0039] Step S5: Calculate the slope direction difference between the natural slope direction and the reference slope direction. For example, if the reference slope direction is due north and the natural slope direction is 15 degrees east of north, calculate the angle difference between the two; and calculate the slope difference between the natural slope and the reference slope. For example, if the reference slope is 10 degrees and the natural slope is 5 degrees, calculate the angle difference between the two; then combine the slope direction difference and the slope difference to judge the difference degree of the sunlight conditions between the slope surface where the seeder is located and the reference slope surface; according to the size of the difference degree of the sunlight conditions, it is also divided into multiple gears, so that it corresponds to the "narrow first-level spacing, narrow second-level spacing..." and "wide first-level spacing, wide second-level spacing..." described above;

[0040] If the sunlight conditions of the slope surface where the seeder is located are the same as those of the reference slope surface, that is, the solar radiation reception amounts are the same, then the seeder uses the reference spacing when sowing, and adjusts the differential to the gear corresponding to the reference spacing;

[0041] If the sunlight conditions of the slope surface where the seeder is located are better than those of the reference slope surface, that is, the solar radiation reception amount of the slope surface where the seeder is located is larger, then the seeder uses a narrower sowing spacing when sowing, and adjusts the differential to the corresponding gear;

[0042] If the sunlight conditions of the slope surface where the seeder is located are worse than those of the reference slope surface, that is, the solar radiation reception amount of the slope surface where the seeder is located is larger, then the seeder uses a wider sowing spacing when sowing, and adjusts the differential to the corresponding gear.

[0043] In summary, when the seeder sows on the slope surface, based on the longitude and latitude information of the area where the seeder is located, as well as the slope and slope direction of the slope surface where the seeder is located, determine the sunlight conditions of the slope surface where the seeder is located. According to the different sunlight conditions of the slope surface where the seeder is located, make the seeder have a smaller sowing spacing on the sunny slope surface and a larger sowing spacing on the shady slope surface. When the sowing spacing is small, adjacent crops are likely to block sunlight from each other, so the advantage of the slope facing the sun will be offset. When the sowing spacing is large, adjacent crops are not likely to block sunlight from each other, so the disadvantage of the slope facing away from the sun will be smoothed out. Therefore, by applying the sowing method in the present invention, the sowing spacing on different slope surfaces can be made more reasonable.

[0044] The above are only the preferred embodiments of the present invention. It should be noted that: for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
