Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to a seeder and its seeding method. Background Technology

[0002] In crop cultivation, such as rice, the seed density and quantity directly affect rice yield. Currently, there are two main rice sowing techniques: row sowing and hill sowing. The number of seeds sown by a row seeder largely depends on its operating speed. Rice seeds are evenly discharged during the seeder's movement and then fall into the corresponding furrows under their own weight. However, this method has a drawback: the seeds are subjected to various forces during their descent, causing them to deviate and not accurately land in the designated holes. This compromises the spacing between rows and plants, ultimately affecting rice yield. Precision seeders can compensate for the shortcomings of row seeders in sowing. Precision seeders consist of a seed box, seed metering device, furrow opener, and soil covering and compaction device. Because the seed outlet of the precision seeder is connected to the furrow, the seeds can be directly sown into the soil holes after they come out of the seed outlet. This avoids uneven planting caused by the deviation of seed weight, ensuring appropriate plant and row spacing in rice planting. The emergence of mechanized seeders has also made up for the shortcomings of high labor intensity and low work efficiency, laying the foundation for high rice yield.

[0003] However, current rice seeders mainly rely on mechanical movement. While they can ensure precise sowing of crops, they cannot automatically adjust the rice grain falling speed according to the length of the row and plant spacing, nor can they adjust the falling speed according to the machine's operating speed. Therefore, these problems urgently need to be solved. Summary of the Invention

[0004] The main objective of this invention is to propose a seed planter and a seeding method for the seed planter, which aims to solve the technical problem that existing seed planters cannot automatically adjust the seeding speed according to the length of the plant spacing.

[0005] To achieve the above objectives, the present invention provides a seeding machine, the seeding machine comprising:

[0006] Seed box, used to store seeds ready for sowing;

[0007] A seed sorting device is placed below the seed box. The seed sorting device is used to receive the seeds flowing out of the seed box and sort them into multiple preset batches.

[0008] The seed dispensing device includes a rotating mechanism and multiple seed storage boxes. The rotating mechanism is used to drive the seed storage boxes to rotate to the seed dispensing position of the seed screening device. Each seed storage box is used to receive a preset batch of seeds.

[0009] A seeding tube, located below the seed storage box, is used to receive seeds flowing out of the seed storage box and to sow them; and

[0010] The control unit, electrically connected to both the seed screening device and the seed dispensing device, is configured as follows:

[0011] Obtain the required row spacing, and control the splitting frequency of the seed screening device and the rotation speed of the rotating mechanism to maintain coupling based on the row spacing information;

[0012] Obtain the positional relationship between the seed storage box and the sowing tube;

[0013] When the seed storage box containing the seeds reaches above the sowing tube, the seed storage box is opened to allow the seeds inside to flow out into the sowing tube for sowing.

[0014] In an embodiment of the present invention, the seed screening device includes a box and a first sensor disposed inside the box. The top surface of the box has a seed inlet, and the bottom surface of the box has multiple rows of seed holes evenly distributed. Seeds are diverted between the seed inlet and the seed holes through a guide tube assembly. The first sensor is used to detect the vibration frequency of the box.

[0015] In an embodiment of the present invention, the seed storage box has an open top and a pointed groove outlet at the bottom, which is covered by a bottom cover that can be automatically opened or closed. When the seed storage box is rotated to the docking position with the sowing tube, the bottom cover opens to allow the seeds in the seed storage box to flow into the sowing tube.

[0016] In an embodiment of the present invention, the plane at the bottom of the plurality of seed storage boxes coincides with the plane at the top of the sowing tube. The seed storage box is made of stainless steel, and the bottom cover is made of a weakly magnetic material. When the seed storage box is rotated to the top of the sowing tube, the bottom cover collides with the sowing tube, thereby opening the bottom cover.

[0017] In an embodiment of the present invention, the seed dispensing device includes a cylindrical disk, a plurality of seed storage boxes are arranged circumferentially at intervals on the outer periphery of the cylindrical disk, the top ends of the plurality of seed storage boxes are located in the same circular plane, and the rotating mechanism is used to drive the cylindrical disk to rotate.

[0018] In an embodiment of the present invention, the rotating mechanism includes a driving gear, a driven gear coaxially connected to the bottom of the cylindrical disk, and a rotating drive member for driving the driving gear to rotate, wherein the driving gear and the driven gear mesh.

[0019] In an embodiment of the present invention, the rotating mechanism further includes a second sensor disposed on the rotating drive member. The second sensor is used to detect the rotational speed of the rotating drive member and send a rotational speed information signal. The control unit is electrically connected to the second sensor and is further configured to:

[0020] Receive the rotation speed information signal and compare the rotation speed information signal of the rotating drive component with the vibration frequency signal of the housing;

[0021] Adjust the rotational speed of the rotary drive and the shunt frequency of the housing based on the comparison results.

[0022] In an embodiment of the present invention, a seeding method for a hill-seeding machine is also provided. This seeding method is applied to the hill-seeding machine described above and includes the following steps:

[0023] Obtain the required preset plant and row spacing information;

[0024] The seed sorting frequency and the rotation speed of the rotating mechanism are kept coupled according to the plant spacing information.

[0025] Drive the seed storage box to rotate in order to receive seeds diverted from the seed sorting device;

[0026] Obtain the positional relationship between the seed storage box and the sowing tube;

[0027] When the seed storage box containing the seeds reaches above the sowing tube, the seed storage box is opened to allow the seeds inside to flow out into the sowing tube for sowing.

[0028] In an embodiment of the present invention, the step of maintaining coupling between the diversion frequency of the seed screening device and the rotation speed of the rotating mechanism based on the row spacing information includes:

[0029] Acquire the vibration frequency signal of the housing and the rotation speed information signal of the rotating drive component;

[0030] Compare the rotational speed information signal of the rotary drive component with the vibration frequency signal of the housing;

[0031] Adjust the rotational speed of the rotary drive and the shunt frequency of the housing based on the comparison results.

[0032] In an embodiment of the present invention, the step of controlling the seed storage box to open when the seed storage box containing the seeds reaches above the sowing tube, so that the seeds in the seed storage box flow out into the sowing tube for sowing, includes:

[0033] When the seed storage box containing the seeds reaches above the sowing tube, the bottom cover of the seed storage box collides with the top of the sowing tube, causing the bottom cover of the seed storage box to open, and the bottom of the seed storage box to connect with the top of the sowing tube to guide the seeds.

[0034] Through the above technical solutions, the seeding machine provided in this embodiment of the invention has the following beneficial effects:

[0035] This application includes a seed sorting device and a seed dispensing device below the seed box. A rotating mechanism in the seed dispensing device drives the seed storage box to the dispensing position of the seed sorting device. Each seed storage box receives a preset batch of seeds. When sowing is required, the control unit first obtains the desired row spacing and, based on this information, controls the flow rate of the seed sorting device and the rotation speed of the rotating mechanism to maintain coupling. The positional relationship between the seed storage box and the sowing tube is also obtained. When the seed storage box containing seeds reaches above the sowing tube, the control unit opens the seed storage box, allowing the seeds to flow out into the sowing tube for sowing. The seed planter of this invention is connected to a tractor, which provides the driving power to the seed planter, thereby causing the seed sorting device to vibrate. A microcomputer processor is installed in the tractor's cab. After inputting the appropriate row and plant spacing required for crop sowing into the microcomputer processor, the control unit processes the data and controls the vibration frequency of the seed sorting device and the seed dispensing speed of the seed dispensing device according to the row and plant spacing. This ensures that the operation of both devices is always synchronized with the speed of the tractor, guaranteeing that each seed storage box contains seeds. Sowing is carried out after the seed storage box passes over the sowing tube, which keeps the row and plant spacing within the optimal dense planting range, saves crop seeds, and increases crop yield.

[0036] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0042] Detailed Implementation

[0043] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] In existing seed planters, seeding is achieved by using machine vibration to drop seeds into a seed storage box on a conveyor belt. The seeds must pass through small holes in the connecting mechanism during this process. When the machine vibration is low, the seeds do not easily fall; when the vibration is high, the holes become clogged, resulting in empty planting holes. Furthermore, the conveyor belt rotates at a constant speed under the action of a motor, and this speed cannot be adjusted or controlled. When the machine's speed is too fast or too slow, it can lead to either excessively sparse or dense planting, which is detrimental to crop yield.

[0045] Therefore, referring to the accompanying drawings, a towed seeder is provided. This seeder is an improvement on seeding machinery technology and can be combined and disassembled with a tractor, making it convenient to use. This seeder can be used to sow agricultural products such as rice and grains.

[0046] like Figure 1 As shown, in an embodiment of the present invention, a seed planter is provided, which includes a seed box 10, a seed sorting device 20, a seed dispensing device 30, a seeding tube 40, and a control unit. The seed box 10 stores seeds to be sown. The seed sorting device 20 is located below the seed box 10 and is used to receive the seeds flowing out of the seed box 10 and divide them into multiple preset batches. The seed dispensing device 30 includes a rotating mechanism and multiple seed storage boxes 31. The rotating mechanism is used to drive the seed storage boxes 31 to rotate to the seed dispensing position of the seed sorting device 20, and each seed storage box 31 is used to receive one preset batch. The seed storage box 31 is located below the seed storage box 31. The seed storage box 31 is used to receive the seeds flowing out of the seed storage box 31 and to sow them. The control unit is electrically connected to the seed screening device 20 and the seed dispensing device 30 and is configured to: obtain the required row spacing; control the flow frequency of the seed screening device 20 and the rotation speed of the rotating mechanism to maintain coupling based on the row spacing information; obtain the positional relationship between the seed storage box 31 and the seeding tube 40; when the seed storage box 31 containing seeds reaches above the seeding tube 40, control the seed storage box 31 to open so that the seeds in the seed storage box 31 flow out into the seeding tube 40 for sowing.

[0047] Compared to existing technologies, the seed planter of this invention is connected to a tractor, with the tractor providing the driving power to the seed planter, thereby driving the vibration of the seed sorting device 20. A microcomputer processor is installed in the tractor's cab. After inputting the appropriate row and plant spacing required for crop sowing into the microcomputer processor, the control unit, after processing, controls the vibration frequency of the seed sorting device 20 and the seed dispensing speed of the seed dispensing device 30 according to the required row and plant spacing, ensuring that both operate synchronously with the tractor's speed. This ensures that each seed storage box 31 contains seeds, avoiding empty holes. Sowing occurs after the seed storage box 31 passes above the sowing tube 40, maintaining the row and plant spacing within the optimal dense planting range, saving crop seeds, and increasing crop yield. Compared to existing technologies, this application can more accurately achieve crop sowing and complete the optimal dense planting required for crop sowing.

[0048] like Figure 2 and Figure 3 As shown, the seed screening device 20 includes a housing 21 and a first sensor 22 disposed within the housing 21. A seed inlet 23 is provided on the top surface of the housing 21, and multiple rows of seed holes 24 are evenly distributed on the bottom surface of the housing 21. Seeds are diverted between the seed inlet 23 and the seed holes 24 via a guide tube assembly. The first sensor 22 is used to detect the vibration frequency of the housing 21. The seed inlet 23 of the housing 21 and the seed outlet of the seed box 10 are connected by a connecting pipe 50. Multiple seed outlets are evenly spaced along the width direction below the seed box 10. Each seed outlet is connected to a seed screening device 20 and a seed dispensing device 30, thereby ensuring that multiple sowing tubes 40 can sow simultaneously, increasing the sowing area and accelerating the sowing speed.

[0049] Furthermore, the diversion tube assembly includes a main diversion tube and multiple branch diversion tubes connected to the main diversion tube. The number of branch diversion tubes is the same as the number of seed holes 24 and they are connected one-to-one. Each branch diversion tube is equipped with a valve to control the on / off state. During diversion, 4 to 5 seeds entering a branch diversion tube are grouped together and fall into the corresponding seed hole 24 through the branch diversion tube.

[0050] Preferably, the bottom surface of the box 21 has three rows of horizontal seed holes 24, each row of seed holes 24 including three seed holes 24, forming a 3*3 seed hole 24 matrix. When the first row of seeds falls into the corresponding three seed storage boxes 31, the seed dispensing device 30 rotates after completion. Then, the next set of empty seed storage boxes 31 in the seed dispensing device 30 is positioned, waiting for the seeds in the second row of seed holes 24 to fall, and so on, to complete the seed storage.

[0051] In an embodiment of the invention, the seed storage box 31 has an open top and a pointed groove-shaped outlet at the bottom, covered by a bottom cover that can open or close automatically. When the seed storage box 31 containing seeds rotates to the docking position with the sowing tube 40, the bottom cover opens to allow the seeds in the seed storage box 31 to flow into the sowing tube 40. The pointed groove-shaped outlet structure at the bottom of the seed storage box 31 facilitates the sequential flow of seeds one by one, preventing blockage of the outlet. During rotation, multiple seed storage boxes 31 rotate in a certain direction.

[0052] In a preferred embodiment, the plane at the bottom of the multiple seed storage boxes 31 coincides with the plane at the top of the sowing tube 40. The seed storage boxes 31 are made of stainless steel, and the bottom cover is made of a weakly magnetic material. When the seed storage box 31 rotates to the top of the sowing tube 40, the bottom cover collides with the sowing tube 40, causing the weakly magnetic bottom cover to lose its magnetism. Under the influence of impact, centrifugal force, and the gravity of the seeds themselves, the bottom cover opens, and the seeds in the seed storage box 31 fall into the sowing tube 40 for sowing. After the flow is complete, the empty seed storage box 31 continues to rotate to other positions, and the weak magnetism of the bottom cover closes again, starting the next round of operation.

[0053] In an embodiment of the present invention, the seed dispensing device 30 includes a cylindrical disk 32, and a plurality of seed storage boxes 31 are evenly spaced around the outer periphery of the cylindrical disk 32. The tops of the plurality of seed storage boxes 31 are located in the same circular plane, and a rotating mechanism is used to drive the cylindrical disk 32 to rotate. The plurality of seed storage boxes 31 are all engaged with the outer periphery of the cylindrical disk 32 via slots for easy disassembly. When seeds enter the housing 21 of the seed sorting device 20 for diversion, they are transferred in groups of 4-5 seeds to a seed storage box 31. The seed storage box 31 then rotates under the rotation of gears. When it passes the sowing tube 40, the bottom of the seed storage box 31 opens under the action of the weight and centrifugal force of the seeds, allowing the seeds to enter the sowing tube 40. When the seed storage box 31 moves away from the sowing tube 40, the bottom of the seed storage box 31 closes, and then the cycle repeats.

[0054] Preferably, the rotating mechanism includes a driving gear 33, a driven gear 34 coaxially connected to the bottom of the cylindrical disk 32, and a rotating drive 35 for driving the driving gear 33 to rotate, wherein the driving gear 33 and the driven gear 34 mesh.

[0055] The rotary drive component 35 is a servo motor, which drives the drive gear 33 to rotate, thereby causing the driven gear 34 and the cylindrical disk 32 to rotate. The rotation of the cylindrical disk 32 causes the empty seed storage box 31 to rotate sequentially to the bottom of the housing 21 to receive seeds flowing from the seed hole 24. Furthermore, the rotation of the cylindrical disk 32 drives the seed storage box 31, which contains seeds, to rotate to the position where it connects with the sowing tube 40 for sowing. This gear-driven rotation method makes the rotation speed of the cylindrical disk 32 more stable and uniform, and also occupies relatively less space.

[0056] In an embodiment of the present invention, the rotating mechanism further includes a second sensor 36 disposed on the rotating drive member 35. The second sensor 36 is used to detect the rotational speed of the rotating drive member 35 and send a rotational speed information signal. The control unit is electrically connected to the second sensor 36 and is further configured to:

[0057] Receive rotation speed information signal and compare the rotation speed information signal of the rotating drive component 35 with the vibration frequency signal of the housing 21;

[0058] Adjust the rotational speed of the rotary drive 35 and the shunt frequency of the housing 21 based on the comparison results.

[0059] In addition, the microcomputer processor control panel can monitor the tractor's operating speed. When the tractor's speed is too high or too low, and the seed dispensing device 30 cannot sow seeds reasonably according to the set row and plant spacing, the microcomputer processor control panel will issue an alarm to remind the driver to make corresponding adjustments. This method can automatically adjust the seed dispensing speed of the seeder according to the tractor's speed, always keeping the row and plant spacing optimal.

[0060] In an embodiment of the present invention, a seeding method for a hill-seeding machine is also provided. The seeding method for the hill-seeding machine is applied to the hill-seeding machine described above, and the seeding method includes the following steps:

[0061] Obtain the required preset plant and row spacing information;

[0062] The splitting frequency of the seed sorting device 20 and the rotation speed of the rotating mechanism are kept coupled according to the row spacing information.

[0063] Drive the seed storage box 31 to rotate to receive seeds diverted from the seed sorting device 20;

[0064] Obtain the positional relationship between the seed storage box 31 and the seed tube 40;

[0065] When the seed storage box 31 containing the seeds reaches above the sowing tube 40, the seed storage box 31 is opened so that the seeds in the seed storage box 31 flow out into the sowing tube 40 for sowing.

[0066] The microcomputer processor, by inputting the sowing row and plant spacing, automatically generates the operating speed of the seed dispensing device 30 by monitoring the machine's running speed, ensuring optimal planting density without being limited by the machine's speed. If the machine speed malfunctions and the seed dispensing device 30's speed cannot meet planting requirements, the microcomputer control panel will issue an alarm to prompt the driver to make appropriate adjustments. This allows the automatic frequency conversion adjustment of the seeder's seed dispensing speed based on the tractor's travel speed, consistently maintaining optimal row and plant spacing.

[0067] This invention enables more precise and accurate sowing of crops, solves the problem of blind seed use, reduces labor costs and seed usage, and can also increase crop yield through reasonable dense planting. In addition, by installing a microcomputer processor in the cab, reasonable dense planting can be achieved by inputting different plant and row spacings and adjusting the seed dispensing speed of the seed dispensing device 30.

[0068] In an embodiment of the present invention, the step of controlling the diversion frequency of the seed sorting device 20 and the rotation speed of the rotating mechanism to maintain coupling based on the row spacing information includes:

[0069] The vibration frequency signal of the housing 21 and the rotation speed information signal of the rotating drive component 35 are acquired.

[0070] Compare the rotation speed information signal of the rotary drive component 35 with the vibration frequency signal of the housing 21;

[0071] Adjust the rotational speed of the rotary drive 35 and the shunt frequency of the housing 21 based on the comparison results.

[0072] A microcomputer control panel is installed in the cab of the agricultural machinery, and the seed screener and the variable frequency seed dispenser are controlled by the control unit to keep them at the same frequency and speed without any delay. This ensures that the seeds falling from the seed screener fall accurately into the seed storage box 31, avoiding the generation of empty sowing holes.

[0073] In an embodiment of the present invention, when the seed storage box 31 containing seeds reaches above the sowing tube 40, the step of controlling the seed storage box 31 to open so that the seeds in the seed storage box 31 flow out into the sowing tube 40 for sowing includes:

[0074] When the seed storage box 31 containing seeds reaches above the sowing tube 40, the bottom cover of the seed storage box 31 collides with the top of the sowing tube 40, so that the bottom cover of the seed storage box 31 opens, and the bottom end of the seed storage box 31 connects with the top end of the sowing tube 40 to guide the seeds.

[0075] To further understand the seeding process of this application, the entire seeding process is described in detail below:

[0076] First, the appropriate plant spacing is input into the microcomputer processor in the machine's cab so that the issued instructions are transmitted to the seed screening device 20 and the seed dispensing device 30 through the first sensor 22 and the second sensor 36, respectively, so as to facilitate the adjustment of the appropriate seed dispensing rate and the synchronization frequency of the two.

[0077] The seeds are then placed in the seed box 10. The seeds in the seed box 10 first pass through the seed sorting device 20. Since the seed sorting device 20 is equipped with a first sensor 22, it can collect the vibration frequency information of the seed sorting device 20 and feed it back to the control unit. The control unit changes the vibration frequency of the seed sorting device 20. After passing through the device, the seeds will be automatically sorted into groups of 4-5 seeds. Then, under the vibration of the box 21 of the seed sorting device 20 and the gravity of the seeds themselves, they fall into the seed storage box 31 below through the 3x3 seed holes 24 at the bottom of the box 21. The arrangement of the seed holes 24 corresponds to the arrangement of the seed storage box 31 below, and the speed and frequency of the two are always kept synchronized.

[0078] Finally, the seed dispensing device 30 rotates by a servo motor driving the drive gear 33 and the driven gear 34 to mesh. The speed of the drive gear 33 can be controlled by the control unit. When the seeds pass through the seed screening device 20, they are transferred to the seed storage box 31 in groups of 4-5. The seed storage box 31 then rotates under the rotation of the gears. When it passes the sowing tube 40, the bottom cover of the seed storage box 31 opens under the action of the weight and centrifugal force of the seeds, allowing the seeds to enter the sowing tube 40. When the seed storage box 31 moves away from the sowing tube 40, the bottom cover of the seed storage box 31 closes, and then the next cycle begins, repeating this process.

[0079] In addition, in order to achieve integrated sowing of the seeder, the entire seeder is equipped with a furrowing mechanism for opening furrows and a soil covering mechanism for covering the soil after sowing. Both the furrowing mechanism and the soil covering mechanism are common structural forms in agricultural seeding machinery, and will not be described in detail here.
