Description

Technical Field

[0001] The present invention belongs to the technical field of crop sowing, and in particular, relates to a rice sowing device with a fertilizing function and a sowing method. Background Art

[0002] Dry direct seeding of rice is a common rice sowing method at present. It is a rice cultivation method that saves water, labor, has high yield and is conducive to full mechanized operation. Moreover, dry direct seeding of rice does not require planting links such as seedling raising, seedling pulling, seedling transporting, and transplanting, which can effectively reduce the labor intensity and also has high economic benefits in the later stage. Therefore, it is highly favored by growers.

[0003] Referring to the Chinese patent with the title: A Paddy and Dry Field Dual-Purpose Rice Direct Seeder (Patent Publication No.: CN117859460A, Publication Date: April 12, 2024), the paddy and dry field dual-purpose rice direct seeder of the present invention can not only remove the deeper wheel ruts generated during the seeding operation of the tractor, which is beneficial to more uniform seeding, but also has the advantage of simple structure and is suitable for dry direct seeding and wet direct seeding work.

[0004] Comparing with the patent (Publication No.: CN117859460A), although it can remove the deeper wheel ruts generated during the progress of the tractor to a certain extent, there are still the following problems:

[0005] 1. In the comparative patent, through the installation columns, soil-returning members and soil-breaking members in the wheel rut removal mechanism, the raised soil is backfilled into the wheel ruts to make the field basically return to its original state. However, the land compacted by the wheels during the seeding process is prone to caking, and it is difficult to completely break up and smooth the caking of the land only by the soil-returning members and soil-breaking members, which will still affect the germination rate of rice seeds.

[0006] 2. At the same time, a row of seeding pipes of its seeder is arranged in a straight line. During the seeding process, when a row of seeding pipes seed through a bend, the seed feeding speed in each pipe remains the same, but the moving distance of each pipe along the bend decreases sequentially from the outside to the inside. As a result, the seeding pipes on the inner side of the bend have excessive feeding or even seed accumulation, which destroys the uniformity of rice planting.

[0007] 3. Therefore, the present invention provides a rice sowing device with a fertilizing function. Summary of the Invention

The flow limiting plate is of a disc-shaped structure and its diameter is smaller than the inner diameter of the second hopper.

[0014] Two auxiliary wheels are further arranged on the front surface of the main beam. The two auxiliary wheels are respectively directly in front of two of the soil-opening members, and the two auxiliary wheels are symmetrically arranged with the towing rod as the center.

[0015] The fertilizer bin and the seed bin have the same size and structure, and discharge ports corresponding to the first hopper and the second hopper respectively are formed at the inner bottom ends of the fertilizer bin and the seed bin.

[0016] The first hopper and the second hopper have the same structure, and a blanking wheel capable of performing intermittent blanking is arranged inside both of them.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention provides a rice sowing device with a fertilizing function. A gully-opening member and a land-leveling mechanism are arranged on the seeder. The gully-opening member performs preliminary leveling and repairing of the ruts during movement. Two soil-leveling modules in the land-leveling mechanism are continuously rotated by a driving mechanism, thereby breaking and loosening the agglomerated soil or raised soil on both sides of the ditch generated by the gully-opening member during movement. The soil is smoothed together with the soil-leveling plate during movement, thereby achieving the operation of thoroughly loosening and smoothing the ruts, thereby providing a guarantee for the expected germination rate of rice.

[0029] 2. The rice sowing device and sowing method with fertilization function are characterized in that a speed sensor is installed on each sowing tube of the seeder. When the seeder is traveling on a curve, the speed sensor detects that the moving speed of the corresponding sowing tube decreases, and the controller of the micromotor controls the micromotor to start the micromotor to drive the current limiting plate to flip from an initial vertical state to a horizontal state, thereby reducing the internal channel space of the sowing tube, thereby achieving the effect of slowing down the feeding speed, thereby ensuring that the seeder has a uniform sowing effect regardless of whether it is in a straight line or a curve.

[0030] 3. The rice sowing device and sowing method with fertilization function are characterized by arranging two silos, a fertilizer silo and a seed silo, on the seeder at the same time. During the sowing process, the fertilizer falls simultaneously along the fertilizer silo and the fertilizer pipe into the ditch opened by the gully opening member, and then the soil is smoothed by the land leveling mechanism, thereby achieving the effects of sowing, fertilizing, burying fertilizer, loosening and smoothing ruts at the same time.

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figure 1-11, the present invention provides a technical solution: a rice seeding device with a fertilizing function, including: a fixedly installed towing bar 1 and a main beam 11, a fertilizer bin 12 is fixedly installed on the main beam 11, a plurality of first funnels 2 are arranged at the bottom end of the fertilizer bin 12, and a fertilizing pipe 21 is fixedly connected to the bottom end of each first funnel 2. The rear side surface of the fertilizer bin 12 is fixedly connected with a seed bin 13, a plurality of second funnels 3 are arranged at the bottom end of the seed bin 13, and a seeding pipe 31 is fixedly connected to the bottom end of each second funnel 3. A plurality of furrowing members 14 are also arranged on the outer surface of the main beam 11 for furrowing and turning over the soil of the ruts. The bottom end of the fertilizing pipe 21 is tied to the rear side surface of the furrowing member 14 so as to sprinkle the fertilizer into the opened ditch. Connect the towing bar 1 to the connecting frame of the tractor. The furrowing member 14 extends downward to an appropriate distance below the ground, and this distance can be adjusted according to the actual situation. And the furrowing member 14 is located directly behind the tractor wheels. During the process of advancing and seeding, the furrowing member 14 initially levels and repairs the ruts generated. At the same time, the fertilizer in the first funnel 2 falls along the fertilizing pipe 21 into the ditch opened by the furrowing member 14 during its advancement, so as to achieve the effect of seeding and fertilizing simultaneously.

[0045] As Figure 1 and Figure 4 shown, two auxiliary wheels 15 are also arranged on the front side surface of the main beam 11. The two auxiliary wheels 15 are respectively located directly in front of two of the furrowing members 14, so that the ruts generated by the auxiliary wheels 15 can be leveled during the advancement of the furrowing member 14. The two auxiliary wheels 15 are symmetrically arranged with respect to the towing bar 1. The fertilizer bin 12 and the seed bin 13 have the same size and structure, and discharge openings corresponding to the first funnels 2 and the second funnels 3 respectively are opened at the inner bottom ends of the fertilizer bin 12 and the seed bin 13. A extension beam 16 is fixedly connected to the rear side surface of the main beam 11. An elastic member 161 is arranged between the extension beam 16 and the soil leveling frame 4 for supporting the soil leveling frame 4 to improve the overall stability. Fertilizer and rice seeds are respectively added into the fertilizer bin 12 and the seed bin 13, and both are provided with sealing covers to prevent the fertilizer and seeds from being jolted out during the seeding process.

[0046] As Figure 4-8 shown, a land leveling mechanism is arranged at the bottom end of the main beam 11 directly behind the furrowing member 14. The land leveling mechanism includes a soil leveling frame 4. Two soil turning modules 41 are arranged inside the soil leveling frame 4. Each soil turning module 41 includes two crushing wheels fixedly connected to a short shaft for crushing the caked soil on both sides of the ditch. As Figure 5It can be seen from the shape and distribution of the shown crushing wheel that the two soil-turning modules 41 are located behind the ditching member 14, and the two soil-turning modules 41 are respectively on both sides of the ditches dug, so the lumpy soil turned out from the ruts can be completely crushed. The rear side surface of the bottom end of the soil-levelling frame 4 is movably connected with a soil-levelling plate 42, which is used to level the loose land, and finally the ruts are completely repaired and the soil is kept in a loose state, providing a guarantee for the expected germination rate after sowing;

[0047] Among them, as Figure 4 , Figure 7 and Figure 8 shown, the structures of the first hopper 2 and the second hopper 3 are the same, and intermittent feeding wheels are arranged through both of them. The outer surfaces of the feeding wheels of every two adjacent first hoppers 2 are fixedly connected with the same first central shaft 22. A first motor 20 for driving its own rotation is also installed on the first central shaft 22 in the middle position. One end of the first central shaft 22 is also provided with a driving mechanism for driving the rotation of the land levelling mechanism. The driving mechanism includes a first protective shell 23 and a second protective shell 25. The internal structures of the first protective shell 23 and the second protective shell 25 are the same and both include a first gear shaft 231 and a second gear shaft 232. A chain is sleeved between the first gear shaft 231 and the second gear shaft 232. The first central shaft 22 is fixedly penetrated into the first gear shaft 231. The top end of the soil-levelling frame 4 is fixedly connected to the outer surface of the second protective shell 25. A second central shaft 24 penetrates through the second gear shaft 232 inside the first protective shell 23. The second central shaft 24 also fixedly penetrates through the first gear shaft 231 at the top end inside the second protective shell 25. The second gear shaft 232 at the bottom end inside the second protective shell 25 is fixedly connected with the short shaft of the soil-turning module 41 through a round shaft. When sowing, the first motor 20 is started to drive the first central shaft 22 to rotate. The first central shaft 22 drives the feeding wheels in each first hopper 2 to rotate at a constant speed, so that the fertilizer in the fertilizer bin 12 falls into the fertilizer pipe 21 and is finally scattered into the ditch along the rear side of the ditching member 14. At the same time, the first central shaft 22 drives the first gear shaft 231 inside the first protective shell 23 to rotate. The first gear shaft 231 drives the second gear shaft 232 to rotate through the chain, and then the second gear shaft 232 drives the second central shaft 24 to rotate. The second central shaft 24 then drives the first gear shaft 231 and the second gear shaft 232 inside the second protective shell 25 to rotate at the same time. Finally, the second gear shaft 232 inside the second protective shell 25 drives the soil-turning module 41 to rotate synchronously, so as to crush and loosen the lumpy or convex soil on both sides of the ditch. Cooperating with the soil-levelling plate 42 during movement to further level the soil, the operations of fertilizing, burying fertilizer, loosening and levelling the ruts can be achieved at the same time, providing a guarantee for the expected germination rate of rice.

[0048] As Figure 9 and Figure 11As shown in the figure, a support mechanism for the seeding tube 31 is provided at an obliquely downward position outside the seed bin 13. The support mechanism includes a first connecting plate 5. A horizontal shaft rod is fixedly connected to the bottom end of the first connecting plate 5. A plurality of fixing frames 52 are fixedly connected to the outer surface of the shaft rod. A through hole for the seeding tube 31 to pass through is provided in each fixing frame 52. A speed sensor 522 is installed on each fixing frame 52 to monitor the moving speed of the seeding tube 31 at this position in real time. A flow limiting mechanism is provided on one side of the outer surface of each seeding tube 31. The flow limiting mechanism includes a bracket 6 fixedly connected to the outer surface of the second hopper 3. A micro motor 61 is fixedly installed on the bracket 6. The output shaft of the micro motor 61 extends into the second hopper 3 movably and is fixedly connected to a flow limiting plate 62. The flow limiting plate 62 is in a disc shape and its diameter is smaller than the inner diameter of the second hopper 3. The flow limiting plate 62 rotates to limit the speed of the seeds falling in the second hopper 3. The speed sensor 522 at the bottom end of each seeding tube 31 is electrically connected to the controller of the micro motor 61 outside the seeding tube 31 for control. When the seeding machine is driving on a curve, when the speed sensor 522 detects that the moving speed of the seeding tube 31 decreases, the controller of the micro motor 61 controls to start the micro motor 61 to drive the flow limiting plate 62 to turn from the initial vertical state to the horizontal state, so that the disc-shaped flow limiting plate 62 reduces the internal channel of the seeding tube 31, thereby achieving the effect of slowing down the feeding speed and avoiding the phenomenon of uneven seeding during seeding on a curve.

[0049] As Figure 3 , Figure 9 and Figure 10 As shown in the figure, the outer surfaces of the feeding wheels of every two adjacent second hoppers 3 are fixedly connected to the same third central shaft 32. A second motor 30 for driving its own rotation is also installed on the third central shaft 32 located in the middle position. The top end of the second motor 30 is fixedly connected to the bottom of the seed bin 13. A second connecting plate 51 is also fixedly connected to the outer surface of the first connecting plate 5. A soil leveling wheel 53 is provided at the bottom end of the second connecting plate 51. Two furrowing wheels 521 are also provided on each fixing frame 52 for furrowing and seeding. The front sides of the two furrowing wheels 521 are close and the rear sides are far away. The bottom end of the seeding tube 31 is located between the two furrowing wheels 521 for spreading the rice seeds into the furrows opened by the furrowing wheels 521. By starting the second motor 30 to drive the third central shaft 32 to rotate, the third central shaft 32 drives the feeding wheels in a plurality of second hoppers 3 to rotate simultaneously, so that the rice seeds in the seed bin 13 fall along the seeding tube 31 and finally fall into the grooves opened by the two furrowing wheels 521. During the progress of the seeding machine, the soil leveling wheel 53 covers the seeds falling into the grooves to complete seeding. The straight-line positions of fertilization and seeding are staggered, and the depth of fertilization is greater than the depth of seeding to avoid the phenomenon of root burning and seedling damage caused by the fertilizer being close to the seeds.

[0050] Working principle: Connect the drawbar 1 to the hitch of the tractor. The ditching member 14 extends downward to an appropriate distance below the ground, and this distance can be adjusted according to the actual situation. At the same time, start the first motor 20 and the second motor 30. The first motor 20 drives the first central shaft 22 to rotate, and the first central shaft 22 drives the feeding wheels in each first hopper 2 to rotate at a uniform speed, so that the fertilizer in the fertilizer bin 12 falls into the fertilizer pipe 21 and finally is scattered into the ditch along the rear side of the ditching member 14. At the same time, the first central shaft 22 also drives the first gear shaft 231 in the first protective shell 23 to rotate. The first gear shaft 231 drives the second gear shaft 232 to rotate through a chain, and further makes the second gear shaft 232 drive the second central shaft 24 to rotate. The second central shaft 24 then drives the first gear shaft 231 and the second gear shaft 232 in the second protective shell 25 to rotate at the same time. Finally, the second gear shaft 232 located inside the second protective shell 25 drives the soil-turning module 41 to rotate synchronously, so as to break and loosen the caked or protruding soil on both sides of the ditch, and cooperate with the leveling plate 42 during movement to level the soil; After the second motor 30 is started, it drives the third central shaft 32 to rotate. The third central shaft 32 drives the feeding wheels in multiple second hoppers 3 to rotate at the same time, so that the rice seeds in the seed bin 13 fall along the seeding pipe 31 and finally fall into the grooves opened by the two ditching wheels 521. During the movement of the seeder, the leveling wheel 53 covers the seeds that have fallen into the grooves to complete seeding.

[0051] A seeding method for a rice seeding device with a fertilizing function, the method comprising the following steps:

[0052] S1. Connect the drawbar 1 to the tractor to drive the whole seeder to move forward, so that the ditching member 14 extends downward to an appropriate distance below the ground. At the same time, start the first motor 20 and the second motor 30 to make the fertilizer and rice seeds fall along the fertilizer pipe 21 and the seeding pipe 31 respectively, and perform fertilization and seeding at the same time;

[0053] S2. The fertilizer is applied into the ditch opened by the ditching member 14, and the rice seeds are applied into the grooves opened by the ditching wheels 521. During the movement of the seeder, the ditching member 14 preliminarily levels and repairs the ruts rolled by the tractor wheels, and the leveling wheel 53 covers the seeds;

[0054] S3. During the fertilization process, the driving mechanism drives the two soil-turning modules 41 in the land leveling mechanism to rotate continuously, which is used to level the loose land, and finally completely repair the ruts and keep the soil in a loose state, providing guarantee for the expected germination rate after seeding;

[0055] S4. When the seeder sows seeds while passing through a curve, the speed sensor 522 located on the seeding tube 31 detects a decrease in the moving speed of the seeding tube 31. Immediately, the speed sensor 522 provides feedback to the controller of the micro-motor 61, causing the controller to start the micro-motor 61 at this location and drive the current-limiting plate 62 to flip from the initial vertical state to the horizontal state, narrowing the internal channel space of the seeding tube 31 and slowing down the material discharging speed of the seeding tube 31, so as to achieve the operation of being able to sow seeds both in a straight line and through a curve.
