Description

Technical Field

[0001] The invention relates to the technical field of mugwort seeding, in particular to a full-automatic mugwort seeding machine and a seeding method. Background Art

[0002] Artemisia argyi, scientific name Artemisia argyi, is an important medicinal plant. Its roots and leaves contain a variety of bioactive ingredients and are widely used in traditional Chinese medicine and health products. As the market demand for Artemisia argyi continues to grow, the traditional manual sowing method can no longer meet the needs of large-scale planting, and it is inefficient and labor-intensive.

[0003] At present, most of the seeding machines on the market are fully automatic or semi-automatic equipment, but most of them are aimed at sowing food crops or cash crops. Compared with general crop seeds, Aigen is mostly in the shape of long strips and is easy to entangle with each other, so conventional seeding devices are difficult to adapt to Aigen seeding. For example, the Chinese patent "A semi-automatic Aigen transplanter" applied for on April 9, 2022, application number: 202221044936.0, although it is suitable for large-scale planting, can save a lot of manpower and has high work efficiency, but it still requires manual participation in Aigen seeding to prevent material blockage.

[0004] The main technical problems of the prior art for sowing Artemisia argyi are as follows:

[0005] 1. Shape and entanglement issues: Artemisia selengensis is mostly in the shape of long strips, and due to its strong fibrous nature, it is easy to get tangled together during the seeding process. Traditional seeders are mostly suitable for more regular seed shapes, such as grains, beans, etc., and are difficult to adapt to the irregular shape of Artemisia selengensis. The irregular shape and entanglement of Artemisia selengensis not only affect the accuracy of seeding, but also easily cause blockage inside the equipment, affecting the continuity of the operation and the seeding quality.

[0006] 2. Poor adaptability of seeding equipment: Existing fully automatic or semi-automatic seeding machines are mostly for conventional food crops or cash crops, and are difficult to apply to long or easily entangled crop seeds. When these seeding machines process irregular seeds such as mugwort, they cannot achieve efficient and stable seeding operations, which easily leads to uneven sowing and affects crop growth and final yield.

[0007] 3. The level of automation is not high enough: Although there are some devices on the market, such as the "A semi-automatic Artemisia argyi transplanter" applied for in 2022 (application number: 202221044936.0), which can achieve semi-automation and save some manual labor, these devices still require manual participation in the planting of Artemisia argyi, and cannot achieve full automation of the sowing process, which increases the use cost and labor intensity, and limits the application of the equipment in large-scale Artemisia argyi planting.

[0008] 4. High risk of blockage: The winding characteristics of Aigen make it easy to get blocked during the transmission, separation and seeding process, which requires stopping the machine to deal with the blockage problem, resulting in interruption of seeding operations, reduced seeding efficiency, increased maintenance and downtime, and further affecting the continuity and stability of operations.

[0009] 5. Insufficient sowing accuracy and efficiency: The existing equipment has low sowing accuracy and uneven planting when sowing mugwort. It is easy to have too much or too little planting, which affects the uniformity of crop growth and yield. This problem is particularly prominent in large-scale planting, affecting the quality and benefits of crops.

[0010] Therefore, the existing sowing technology has technical problems such as low efficiency, poor adaptability, low degree of automation, and easy clogging of the mugwort when adapting to the special needs of mugwort sowing. There is an urgent need for a specially designed automated equipment that can effectively handle the long strip shape of mugwort and improve sowing accuracy to solve these problems. Summary of the invention

[0011] In order to overcome the problems of existing semi-automatic mugwort seeding machines requiring manual participation, low planting efficiency, high operating cost, and easy blockage of mugwort, the present invention provides a fully automatic mugwort seeding machine which is easy to operate, low cost, good adaptability, high sowing efficiency, and good sowing uniformity.

[0014] The reducer is the power source of the Aigen orderly separation device. The Aigen orderly separation device is connected to the first shaft and the second shaft. The reducer is combined with the fourth shaft. The fourth shaft is connected to one end of the third shaft through a third chain. The third shaft is connected to one end of the second shaft through a second chain. The third shaft is connected to one end of the first shaft through a first chain, providing seeding power for the Aigen orderly separation device.

[0015] The travel wheel is the power source of the outer groove wheel seeding device, the outer groove wheel seeding device is connected to the fifth shaft, the fifth shaft and one end of the sixth shaft are connected through the fourth chain, and the travel wheel transmits power to the outer groove wheel seeding device through the fourth chain;

[0016] The furrowing plow and the double-disc soil covering device are fixed to the lower part of the frame through fasteners. The front end of each feeding pipe is provided with a furrowing plow, and the rear end of each seed feeding pipe is provided with a double-disc soil covering device.

[0017] Furthermore, the tensioning device is installed on the fourth chain.

[0018] Furthermore, the travel wheel is mounted on the wheel frame via a sixth axis.

[0019] Furthermore, the wheel frame is installed on the frame.

[0020] Furthermore, support plates are provided on both sides of the frame, wherein a first support plate, a second support plate and a third support plate are installed close to the chain side.

[0021] The present invention also provides a fully automatic method for sowing Artemisia argyi, comprising the following steps:

[0022] 1. The Artemisia argyi in the seed box is discretely processed by the Artemisia argyi discrete-order separation device to separate the entangled Artemisia argyi;

[0023] 2. Use the outer groove wheel seeding device to orderly discharge the discrete mugwort roots and accurately sow the mugwort roots to the predetermined position through the seed delivery tube;

[0024] 3. Before sowing the Artemisia selengensis, use a furrowing plow to dig furrows on the ground to ensure that the Artemisia selengensis falls into the preset furrows;

[0025] 4. Use the double-disc soil coverer to cover the seeds after they fall into the seed furrow to ensure even seed coverage.

[0026] Furthermore, the discrete processing in step 1 is completed by driving the orderly separation device of the mugwort roots through the chain transmission of the first shaft, the second shaft and the third shaft, so as to achieve uniform separation of the entangled mugwort roots in the seed box.

[0027] Furthermore, the orderly seeding in step 2 is completed by the rotational movement of the outer groove wheel seeding device, which is powered by the walking wheel and realizes the precise and orderly seeding of Aigen through chain transmission.

[0028] Furthermore, the soil covering operation in step 4 is performed by a double-disc soil covering device, which works in conjunction with a furrowing plow to ensure that the soil is covered immediately after the Artemisia selengensis falls into the seed furrow to avoid the seeds being exposed.

[0029] Beneficial effects of the present invention:

[0030] First, the present invention adopts an orderly separation device of Aigan based on two differential belts, which can realize the orderly separation of irregularly entangled Aigan. The orderly separation device of Aigan and the outer groove wheel seeding device described in the present invention use two separations of Aigan to realize fully automatic precision strip sowing of Aigan. The power of the orderly separation device of Aigan described in the present invention comes from the tractor and does not require external power. The fully automatic Aigan seeder described in the present invention has no human participation in the entire process of sowing, which saves costs and improves sowing efficiency.

[0031] Second, the technical solution of the present invention solves various problems existing in the prior art through a fully automatic mugwort seeding machine, especially in terms of low mugwort seeding efficiency, high labor costs, uneven seeding, and inability to cope with complex environmental conditions in different seasons and regions. The present invention can effectively solve the problem of mugwort being tightly entangled and difficult to separate through an innovative mugwort discrete-order separation device, realize automatic and orderly separation and seeding of mugwort, and significantly improve seeding uniformity and seeding quality.

[0032] Compared with the traditional purely manual or semi-automatic sowing method, the present invention adopts an outer groove wheel seeding device, a reducer-chain transmission composite transmission device and a ditching-covering device, which combines the advanced design of mechanization and automation, not only improves work efficiency, but also reduces manual intervention and reduces production costs. The promotion and application of this seeder can achieve a planting efficiency of more than 30 mu / day, and it is expected to save 70 yuan per mu (increase income). The national cultivation area of ​​wormwood reaches 1 million mu, and the farmers' planting link is expected to increase income by 70 million yuan.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] The invention discloses a fully automatic mugwort seeding machine, and relates to the technical field of mugwort seeding. The seeding machine comprises a mugwort discrete-order separation device, an outer groove wheel seeding device, a reducer-chain transmission compound transmission device, a furrowing-soil covering device, a seed box and a frame. There are four running wheels, which are respectively arranged on the front and rear sides of the frame. The seed box is installed at the top of the frame and is used to store mugwort. The mugwort discrete-order separation device is installed at the upper end of the frame and is located below the seed box, and is used to discrete the mugwort in the seed box. The outer groove wheel seeding device is installed in the middle of the frame and is located below the mugwort discrete-order separation device, and is used to orderly separate the discrete mugwort. Then the mugwort falls to the ground through a seed transporting pipe. The furrowing-soil covering device performs furrowing before the mugwort falls to the ground, and performs soil covering after the mugwort falls into the seed furrow to complete the seeding. The reducer-chain transmission compound transmission device is the power source of the mugwort discrete-order separation device, and the running wheel is the power source of the outer groove wheel seeding device. The invention can save a lot of labor, has high work efficiency, saves costs, and can achieve orderly separation and sowing of tightly entangled mugwort roots, and adapt to the requirements of mugwort sowing in different seasons and different regions. The tractor output power can drive the seed meter to separate and orderly separate the tightly entangled mugwort roots through the reducer, and can save a lot of labor and have high work efficiency. It has the advantages of reasonable structural design, adaptability to mugwort sowing, and high sowing efficiency.

[0041] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, a fully automatic Aigen seeder is connected to a reducer 14 by a tractor three-point suspension method to tow the fully automatic Aigen seeder.

[0043] like Figure 2 As shown, the reducer 14 is combined with the fourth shaft 13, and the fourth shaft 13 is connected to one end of the third shaft 11 through the third chain 12, so that the power of the fourth shaft 13 is transmitted to the third shaft 11 through the third chain 12, the third shaft 11 is connected to one end of the second shaft 8 through the second chain 9, and the third shaft 11 is connected to one end of the first shaft 6 through the first chain 7, so that the power of the third shaft 11 is transmitted to the first shaft 6 and the second shaft 8, driving the first shaft 6 and the second shaft 8 to rotate, thereby making the Aigen orderly separation device 10 work.

[0044] like Figure 2 As shown, when the tractor is pulling, the running wheel 26 will rotate, and the rotation of the running wheel 26 is transmitted to the fifth shaft 15 of the outer groove wheel seed metering device 17 through the fourth chain 16, so that the outer groove wheel seed metering device 17 works.

[0045] like Figure 3 As shown, the left side of the frame 1 is provided with a first support plate 2, a second support plate 3 and a third support plate 4, which are aesthetically pleasing and can protect the first chain 7, the second chain 9, the third chain 13 and the fourth chain 16 from working properly.

[0046] like Figure 1 As shown, the cross section of the furrowing plow 22 is triangular: strong and easy to dig. The seed delivery tube 21 is installed at the rear end of the furrowing plow 22, and the mugwort root is discharged along the seed delivery tube 21 and falls to the ground. At this time, the furrowing plow 22 has already dug a furrow on the ground, and the mugwort root just falls into the dug seed furrow. Then, the double-disc soil cover 23 covers the mugwort root with soft soil to complete the planting process.

[0047] The fully automatic Aigen seeder is connected to the reducer 14 by a tractor three-point suspension to achieve the overall traction function. Through this structural design, the tractor can provide stable power output for the seeder to adapt to different farmland conditions and operation requirements. The reducer 14 reduces the power transmission speed and converts the high speed provided by the tractor into a low speed output suitable for each working component of the seeder to ensure accuracy and stability during the sowing process.

[0048] During the power transmission process, the reducer 14 is connected to the fourth shaft 13, and the power is transmitted to the third shaft 11 through the third chain 12. The third shaft 11 is then connected to the second shaft 8 through the second chain 9, and the first chain 7 transmits the power of the third shaft 11 to the first shaft 6. This transmission chain system ensures the synchronous rotation of the first shaft 6 and the second shaft 8, thereby driving the orderly separation device 10 of the wormwood to work, so that the tightly wound wormwood can be gradually separated and seeded.

[0049] The outer groove wheel seed metering device 17 obtains power through the rotation of the running wheel 26. As the tractor is pulled, the running wheel 26 starts to rotate, and the rotation power is transmitted to the fifth shaft 15 of the outer groove wheel seed metering device 17 through the fourth chain 16, so that the outer groove wheel seed metering device 17 can stably and orderly discharge the separated mugwort roots into the seed delivery tube 21. This design ensures the stable delivery of seeds during the sowing process and avoids the seed blockage or uneven seeding phenomenon that occurs in traditional sowing.

[0050] In order to protect the normal operation of the entire mechanical system, the first support plate 2, the second support plate 3 and the third support plate 4 are installed on the left side of the frame 1. These support plates not only have the function of aesthetics, but also provide effective protection for the first chain 7, the second chain 9, the third chain 12 and the fourth chain 16. The design of the support plate ensures that the chain system will not be disturbed by external factors such as soil and stones in the complex field environment, thereby extending the service life of the equipment.

[0051] The cross section of the furrowing plow 22 is designed in a triangular shape, which ensures its furrowing efficiency and strength in the soil. The triangular structure not only improves the strength of the furrowing plow 22 and can withstand greater operating force, but also can quickly and neatly open a seed furrow on the ground to prepare for the subsequent sowing of mugwort. This structural design is suitable for various soil conditions, especially hard soil and soil with high water content, and can also maintain a high furrowing efficiency.

[0052] The seed delivery tube 21 is installed at the rear end of the furrowing plow 22. After the mugwort is discharged through the outer groove wheel seeding device 17, it falls to the ground along the seed delivery tube 21. At this time, the furrowing plow 22 has already opened a suitable seed furrow on the ground in advance to ensure that the mugwort seeds can accurately fall into the seed furrow. This design effectively prevents the seeds from being scattered outside the seed furrow and ensures the accurate planting position of each seed.

[0053] After the mugwort seeds fall into the seed furrow, the double-disc soil coverer 23 immediately completes the soil covering operation. The double-disc soil coverer 23 rotates to cover the sown mugwort with soft soil, ensuring the depth and uniformity of seed coverage. This soil covering method not only effectively protects the seeds, but also provides a suitable environment for seed germination and growth, while preventing the exposed seeds from being blown away by the wind or affected by other external forces.

[0054] The fully automatic Aigan seeder achieves the integrated operation of orderly separation of Aigan seeds, furrowing, sowing and covering soil through a series of precise structural designs. This design greatly improves the sowing efficiency and quality, especially in farmland scenarios that require a large amount of sowing operations, which can significantly reduce labor costs and improve operating efficiency. The equipment has a reasonable structure and can adapt to the Aigan operation needs of different seasons and regions.

[0055] The fully automatic Aigen seeder is connected to the reducer 14 through the tractor three-point suspension, realizing the traction and power transmission functions of the seeder as a whole. The tractor stably transmits high-speed power to the seeder through the device, and the reducer 14 converts the high speed into a low speed suitable for each component of the seeder, thereby ensuring the smooth output and accuracy of power during the sowing process. This design enables the seeder to work flexibly under various field conditions and adapt to different soils, terrains and farming needs.

[0056] During the power transmission process, a series of chains and shaft systems are used to achieve multi-stage power transmission. The power of the reducer 14 is transmitted to the third chain 12 through the fourth shaft 13, and then connected to the third shaft 11 through the third chain. The third shaft 11 is connected to the second shaft 8 through the second chain 9, and finally transmits the power to the first shaft 6 through the first chain 7. In this way, the first shaft 6 and the second shaft 8 rotate synchronously, driving the Aigen separation device 10 to gradually separate the Aigen and enter the seeding process. This multi-stage chain transmission design not only ensures the orderly operation of the equipment, but also avoids excessive vibration and instability in power transmission.

[0057] After the separation of mugwort root is completed, the separation device 10 transfers the separated mugwort root to the outer groove wheel seed meter 17. The walking wheel 26 rotates under the traction of the tractor, and the fourth chain 16 transmits the rotational power to the fifth shaft 15, and then the fifth shaft 15 drives the outer groove wheel seed meter 17. Through this system, the seed meter 17 can stably transport the mugwort root seeds to the seed delivery tube 21, realizing accurate and orderly seeding, avoiding seed blockage or unevenness caused by instability in the traditional sowing process, thereby ensuring sowing efficiency and sowing quality.

[0058] During the sowing process, the triangular cross-section design of the furrowing plow 22 can quickly open a seed furrow in the soil. The triangular structure enhances the strength of the furrowing plow, allowing it to maintain stability when applying force and adapt to hard or wet soil conditions. The furrows opened in this way are not only regular in shape, but also provide a stable foundation for the subsequent sowing operation, ensuring the precise placement of the Aigen seeds, thereby improving the uniformity and consistency of sowing.

[0059] Once the furrowing is completed, the outer groove wheel seeding device 17 discharges the mugwort seeds into the opened furrows along the seed delivery tube 21. The seed delivery tube 21 is located at the rear end of the furrowing plow 22 to ensure that the seeds fall accurately into the predetermined furrows and prevent the seeds from being scattered outside the furrows. Such a position design ensures that the planting position of each mugwort seed can be accurately controlled, improves the uniformity of sowing, and thus optimizes the field operation effect.

[0060] After sowing is completed, the double-disc soil cover 23 rotates to cover the loose soil in the sown seed furrow. The double-disc design ensures the uniformity and stability of the soil covering, and reaches an appropriate soil covering depth, which not only effectively protects the seeds from external factors (such as wind or rain erosion), but also provides a suitable environment for seed germination and initial growth. This process ensures the growth conditions of the Artemisia argyi seeds and ensures the healthy development and survival rate of the plants.

[0061] Through the coordinated operation of the above multiple modules, the fully automatic Aigan seeder realizes the integrated operation of Aigan seed separation, furrowing, sowing and covering. The whole machine is precisely designed and has good environmental adaptability, which can meet the needs of farmland operations in different seasons and regions. The equipment has a compact and reasonable structure, which can significantly improve the efficiency of farmland sowing and reduce labor costs, making it a reliable tool for efficient sowing in modern agricultural production.

[0062] Example 1: Fully automatic sowing of Artemisia argyi on flat land

[0063] In a flat farmland environment, a fully automatic Aigen seeder is used for Aigen sowing. The seeder is towed by a tractor with three-point suspension, and the tractor provides power and transmits it to the entire sowing system through a reducer 14. The specific operation process is as follows:

[0064] 1. Equipment preparation: Place the Artemisia argyi seeds into the seed box 5, and ensure that the Artemisia argyi discrete-order separation device 10, the outer groove wheel seed metering device 17 and the reducer-chain drive composite transmission device operate normally.

[0065] 2. Seeding process:

[0066] The tractor starts, pulling the seeder forward, and the travel wheel 26 rotates accordingly, transmitting power to the outer groove wheel seeding device 17 through the fourth chain 16, and seeding begins.

[0067] At the same time, the reducer 14 drives the first shaft 6 and the second shaft 8 through the chain system, driving the artemisia argyi discrete-order separation device 10 to separate the entangled artemisia argyi seeds into single seeds for discharge.

[0068] The furrowing plow 22 opens uniform seed furrows on the ground, and the mugwort seeds fall into the seed furrows through the seed delivery tube 21.

[0069] The double-disc soil cover 23 then covers the seeds with soil to complete the sowing.

[0070] 3. Result: During the land preparation process, the seeder successfully completed the sowing operation of Artemisia argyi on flat ground, the seeds were evenly covered, and the furrowing and soil covering were consistent, which significantly improved the work efficiency.

[0071] Example 2: Fully automatic sowing of Artemisia selengensis in hilly areas

[0072] In a hilly area with complex terrain, a fully automatic Aigan seed drill was used for operation. The slope was large in this environment, but by adjusting the suspension height and power transmission of the equipment, the seed drill was still able to successfully complete the seeding of Aigan.

[0073] 1. Equipment adjustment: According to the slope of the hilly terrain, adjust the suspension height of the seeder through the tractor suspension system to ensure the smooth operation of the equipment. Adjust the reducer 14 to match the working speed of the seeder.

[0074] 2. Seeding process:

[0075] The tractor pulls the seeder on the hilly terrain, and the traveling wheel 26 can still provide stable power transmission despite the terrain changes, and the outer groove wheel seeding device 17 starts to seed stably.

[0076] The Aigen discrete-order separation device 10 maintains a stable seed separation efficiency through chain transmission, ensuring that the seeds are not blocked even on uneven terrain.

[0077] The furrowing plow 22 accurately digs furrows on terrains with different slopes, and the seed delivery tube 21 evenly spreads the mugwort seeds into the furrows, which are then covered with soil by the double-disc soil coverer 23 .

[0078] 3. Result: The sowing task of Aigen was completed in the hilly area. The adaptability of the equipment ensured that the sowing quality was not affected by the changes in terrain.
