[0020] A traditional Chinese medicine seed sowing machine with adjustable sowing density includes a sowing housing 1, and also includes: a grooving mechanism 2 rotatably arranged in front of the sowing housing 1 for opening planting grooves, a pressing mechanism 3 rotatably arranged behind the sowing housing 1 for pressing the planting grooves, a sowing mechanism 4 installed above the sowing housing 1 and arranged between the grooving mechanism 2 and the pressing mechanism 3 for sowing, and a driving mechanism 5 arranged inside the sowing housing 1 for driving the sowing housing 1 to move forward through the grooving mechanism 2 and the pressing mechanism 3 and simultaneously for driving the sowing mechanism 4 to sow; an adjustable feeding unit 43 for adjusting the seed taking amount is arranged inside the sowing mechanism 4, and a material conveying unit 44 for conveying seeds and cooperating with the feeding unit 43; the driving mechanism 5 drives the feeding unit 43 to quantitatively obtain seeds from inside the sowing mechanism 4 as required and put them into the material conveying unit 44 to carry out seed sowing work with adjustable density.

[0021] Furthermore, the grooving mechanism 2 includes: a grooving wheel 21 rotatably arranged in front of the sowing housing 1 for the movement of the sowing housing 1, and an annular grooving knife 22 arranged at the edge of the grooving wheel 21 for breaking the soil layer. When the grooving wheel 21 rotates, the annular grooving knife 22 arranged at its edge opens sowing grooves; Among them, the grooving mechanism 2 is in a butterfly shape, and can increase the pressure on the soil through the relatively narrow area at the edge of the annular grooving knife 22, so that the grooving mechanism 2 is more likely to break the soil layer to form planting grooves; Among them, regarding the specific implementation of the grooving mechanism 2, special attention should be paid to the installation angle and sharpness maintenance of the annular grooving knife 22. The annular grooving knife 22 should be installed at an inclination angle of 15 to 30 degrees at the edge of the grooving wheel 21. This angle can not only ensure the smoothness of cutting into the soil, but also reduce the soil resistance. Before actual operation, it is necessary to check whether the edge of the annular grooving knife 22 is sharp. A dull knife edge will cause uneven grooving and affect the subsequent sowing quality. The grooving depth can be achieved by adjusting the counterweight on the sowing housing 1. The counterweight can be reduced in soft soil and increased in compacted soil. The rotational speed of the grooving wheel 21 should be controlled at 30 to 50 revolutions per minute. Too fast will result in too shallow grooving, and too slow will affect the operation efficiency. After each operation, it is necessary to promptly clean the soil and weeds attached to the annular grooving knife 22 to prevent rust.

[0022] Further, the pressing mechanism 3 includes: a pressing wheel 31 rotatably arranged behind the sowing housing 1 for the movement of the sowing housing 1, and a rubber pressing sleeve 32 arranged at the edge of the pressing wheel 31 for pressing the sowing groove. When the pressing wheel 31 rotates, the rubber pressing sleeve 32 arranged at its edge presses the sowing groove after the seeds are put in. Among them, the pressing mechanism 3 presses the sowing groove after the seeds are put in, so that the seeds fit more closely with the soil, which is beneficial to the rooting and germination of the seeds.

[0023] Further, the sowing mechanism 4 includes: a seed storage housing 41 fixedly connected above the sowing housing 1 for storing seeds, and a sealing cover 42 rotatably installed above the seed storage housing 41 for sealing the seed storage housing 41; the feeding unit 43 is rotatably arranged on one side inside the seed storage housing 41, and the material conveying unit 44 is arranged on the other side inside the seed storage housing 41; the material conveying unit 44 includes an aggregate hopper 441 arranged on the side wall of the seed storage housing 41 and a discharge pipe 442 connected to the bottom of the aggregate hopper 441 for feeding seeds into the sowing groove; the feeding unit 43 includes a feeding turntable 431 rotatably arranged inside the seed storage housing 41, mounting holes 432 evenly opened at the edge of the feeding turntable 431, and seed scoops 433 detachably installed inside the mounting holes 432 and capable of scooping seeds from the seed storage housing 41 during the rotation of the feeding turntable 431. The seed scoops 433 cooperate with the aggregate hopper 441. Among them, a relatively large number of mounting holes 432 are arranged at equal intervals at the edge of the feeding turntable 431. If the user wants to increase the plant spacing, the number of seed scoops 433 on the feeding turntable 431 can be reduced, so that the frequency of seeds delivered into the aggregate hopper 441 when the feeding turntable 431 rotates is reduced. On the contrary, if the user wants to shorten the plant spacing, the number of seed scoops 433 on the feeding turntable 431 can be increased, so that the frequency of seeds delivered into the aggregate hopper 441 when the feeding turntable 431 rotates is increased, so as to change the planting density of traditional Chinese medicines. However, no matter how the number of seed scoops 433 is adjusted, it should be ensured that the seed scoops 433 on the feeding turntable 431 are arranged at equal intervals, so as to facilitate the equal-spacing delivery of seeds and thus obtain equal plant spacing. Of course, users can also change the planting density by selectively putting traditional Chinese medicine seeds into the interior of the seed storage housing 41. For example, traditional Chinese medicine seeds can be put into the interior of the first seed storage housing 41, and then, skipping one seed storage housing 41, put traditional Chinese medicine seeds into the interior of the third seed storage housing 41, ensuring that there are no traditional Chinese medicine seeds put into the interior of the intermediate skipped seed storage housing 41. In this way, the row spacing between adjacent Chinese medicinal materials can be increased during sowing. Users can choose the number of seed storage housings 41 left empty in the middle according to their needs to obtain the most suitable row spacing, and thereby can also change the planting density of Chinese medicinal materials; Among them, for the implementation of the feeding unit 43, attention should be paid to the selection and installation of the seed scoops 433. The seed scoops 433 should be selected in different volumes according to the size of the seeds, and generally 3 to 5 specifications should be prepared for standby. During installation, it is necessary to ensure that all the seed scoops 433 have the same installation angle on the feeding turntable 431, usually maintaining an angle of 45 degrees with the horizontal plane, and this angle is most conducive to scooping and pouring seeds. During actual operation, the rotation speed of the feeding turntable 431 should be adjusted according to the characteristics of the seeds. For larger and heavier seeds, the rotation speed should be slowly controlled at 10 to 15 revolutions per minute, and for smaller and lighter seeds, it can be appropriately increased to 15 to 20 revolutions per minute. Regularly check the wear condition of the seed scoops 433. Severely worn seed scoops 433 will result in inaccurate seed scooping quantity, and they should be replaced in time. When changing to different varieties of seeds, the remaining seeds in the seed storage housing 41 must be thoroughly cleaned to prevent variety mixing.

[0024] Further, the driving mechanism 5 includes: a driving motor 51 installed inside the sowing housing 1, a first rotating shaft 53 fixedly connected through the center of the grooving wheel 21 for driving the grooving wheel 21 to rotate, a second rotating shaft 56 fixedly connected through the center of the pressing wheel 31 for driving the pressing wheel 31 to rotate, and a third rotating shaft 59 fixedly connected through the center of the feeding turntable 431 for driving the feeding turntable 431 to rotate. The first rotating shaft 53, the second rotating shaft 56, and the third rotating shaft 59 are all rotatably connected to the sowing housing 1. The third rotating shaft 59 is simultaneously rotatably connected to the seed storage housing 41 and the aggregate hopper 441. A driving pulley 52 is installed at the power output end of the driving motor 51. The driving pulley 52 is arranged outside the sowing housing 1. A first transmission belt 55, a second transmission belt 58, and a third transmission belt 511 are simultaneously sleeved on the driving pulley 52. A first pulley 54 is fixedly installed at one end of the first rotating shaft 53 outside the sowing housing 1. The driving pulley 52 is in transmission connection with the first pulley 54 through the first transmission belt 55. A second pulley 57 is fixedly installed at one end of the second rotating shaft 56 outside the sowing housing 1. The driving pulley 52 is in transmission connection with the second pulley 57 through the second transmission belt 58. A third pulley 510 is fixedly installed at one end of the third rotating shaft 59 outside the sowing housing 1. The driving pulley 52 is in transmission connection with the third pulley 510 through the third transmission belt 511; Among them, special attention should be paid to the adjustment of the belt tension during the implementation of the driving mechanism 5. The tension of the first transmission belt 55, the second transmission belt 58, and the third transmission belt 511 should be moderate. Too loose will cause slipping, and too tight will accelerate the wear of the bearings. It is recommended to check the belt condition once a week, and replace the belt with cracks or severe wear in time. The power selection of the driving motor 51 should be determined according to the working width. Generally, a power reserve of 0.5 to 0.8 kilowatts is required per meter of working width. During long-term continuous operation, pay attention to monitoring the temperature of the driving motor 51 to avoid overheating damage. The lubrication of each rotating shaft is also crucial. The bearings of the first rotating shaft 53, the second rotating shaft 56, and the third rotating shaft 59 should be filled with grease every 50 hours of operation. When operating in rainy weather, do a good job in waterproof protection of transmission components such as the driving pulley 52.

[0025] Further, it also includes: a soil covering mechanism 6, the soil covering mechanism 6 includes a mounting frame 61 with both ends fixedly connected to the inner wall of the seeding housing 1, a sliding rod 62 vertically and movably inserted into the interior of the mounting frame 61, a soil covering angle iron 63 fixedly connected to the bottom of the sliding rod 62 and inclined, and a resistance spring 64 sleeved outside the sliding rod 62 and arranged between the mounting frame 61 and the soil covering angle iron 63 for pushing the soil covering angle iron 63 downward. A stop block for preventing the sliding rod 62 from falling off is fixedly connected to the top end of the sliding rod 62 above the mounting frame 61. The soil covering angle iron 63 is arranged corresponding to the grooving mechanism 2 and the pressing mechanism 3. The soil covering angle iron 63 is arranged behind the discharge pipe 442. The soil covering angle iron 63 is used for covering the planting grooves filled with seeds with soil; Among them, the key to the implementation of the soil covering mechanism 6 lies in the pre-tightening force adjustment of the resistance spring 64. The pre-tightening force of the resistance spring 64 should be adjusted according to the soil humidity. For dry soil, a smaller pre-tightening force of about 5 to 10 kg is required, while for wet and sticky soil, a larger pre-tightening force of about 15 to 20 kg is needed. The installation angle of the soil covering angle iron 63 is recommended to be kept between 30 and 45 degrees. This angle range can ensure the best soil covering effect. During operation, it is necessary to regularly check whether the sliding of the sliding rod 62 is smooth. When jamming occurs, the accumulated soil should be cleaned in time and lubricating oil should be added. When transferring plots or transporting, the soil covering angle iron 63 should be lifted through the lifting mechanism to avoid collision and deformation. The soil covering depth can be controlled by adjusting the height of the mounting frame 61. Generally, it is appropriate to cover the seeds by 2 to 3 cm. Different seeds require different soil covering depths, and corresponding adjustments should be made before sowing.

[0026] Further, a soil scraping plate 7 is arranged behind the seeding housing 1. The soil scraping plate 7 is attached to one side of the pressing mechanism 3. The soil scraping plate 7 is used for scraping the soil on the surface of the rubber pressing sleeve 32; Among them, regarding the specific implementation of the soil scraping plate 7, special attention needs to be paid to the adjustment of the cooperation gap with the pressing wheel 31. The soil scraping plate 7 should maintain a gap of 1 to 2 mm with the surface of the rubber pressing sleeve 32. This gap can effectively scrape off the attached soil without excessive wear on the rubber surface. During actual operation, the angle of the soil scraping plate 7 should be adjusted according to the soil viscosity. For sticky soil, it is recommended to set the angle between the soil scraping plate 7 and the tangent of the pressing wheel 31 at 30 degrees, while for sandy soil, it can be adjusted to 45 degrees. The material of the soil scraping plate 7 is recommended to be 65Mn spring steel, and the thickness is controlled at 3 to 5 mm, which can ensure both rigidity and certain elasticity. Before each operation, it is necessary to check the wear condition of the cutting edge of the soil scraping plate 7. When the cutting edge thickness exceeds 1 mm, it should be ground or replaced in time. During long-term operation, the soil accumulated on the back of the soil scraping plate 7 should be cleaned regularly to avoid affecting the soil scraping effect.

[0027] Furthermore, a placement groove 11 is provided above the sowing outer shell 1. The placement groove 11 is disposed corresponding to the upper part of the grooving mechanism 2. The placement groove 11 is used to press down the grooving mechanism 2 by placing heavy objects inside it. The driving motor 51 is installed inside the placement groove 11. Among them, when using the placement groove 11, attention should be paid to the counterweight selection and installation method. The total weight of the counterweight in the placement groove 11 should be controlled within the range of 20 to 50 kilograms according to the soil hardness. If it is too light, the grooving depth will be insufficient; if it is too heavy, the equipment load will increase. It is recommended that the counterweight blocks adopt a modular design, with each block being 5 kilograms, which is convenient for increasing or decreasing according to actual needs. During installation, it is necessary to ensure that the counterweight blocks are evenly distributed in the placement groove 11 to avoid the center of gravity shifting and affecting the balance of the equipment. When the driving motor 51 is installed in the placement groove 11, attention should be paid to doing a good job in waterproof and dustproof measures, and it is recommended to install a protective cover. During transportation and transfer, all the counterweights in the placement groove 11 should be removed to reduce the weight of the equipment. When operating in different seasons, the counterweight should be adjusted according to the soil moisture content. In spring with moist soil, the counterweight can be appropriately reduced; in autumn with dry soil, the counterweight needs to be increased.

[0028] In summary, during use, first of all, the operator needs to preliminarily adjust the Chinese herbal medicine seed sowing machine with adjustable sowing density according to the characteristics and planting requirements of Chinese herbal medicine seeds. Open the sealing cover 42 above the seed storage outer shell 41, and pour the prepared seeds into the interior of the seed storage outer shell 41. According to the required plant spacing, select an appropriate number of seed-taking spoons 433 and install them equidistantly in the mounting holes 432 on the edge of the feeding turntable 431. If it is necessary to increase the plant spacing, reduce the number of seed-taking spoons 433; conversely, increase the number. At the same time, select an appropriate model of the seed-taking spoon 433 according to the seed size to ensure that the amount of seeds taken each time meets the requirements.

[0029] Next, the operator needs to adjust the parameters of the grooving mechanism 2 and the soil covering mechanism 6 according to the soil conditions. Add appropriate counterweight blocks in the placement groove 11 above the sowing outer shell 1 to control the grooving depth of the annular grooving knife 22. For soft soil, reduce the counterweight; for compacted soil, increase the counterweight. At the same time, adjust the angle of the soil covering angle iron 63 and the pre-tightening force of the resistance spring 64 to ensure that the soil covering depth is between 2 and 3 centimeters. If the soil has high viscosity, the angle of the soil covering angle iron 63 can be adjusted smaller; if the soil is relatively loose, the angle can be appropriately increased.

[0030] After the adjustment is completed, the drive motor 51 is started and the drive mechanism 5 begins to work. The drive motor 51 drives the first transmission belt 55, the second transmission belt 58 and the third transmission belt 511 through the drive pulley 52, which respectively drive the slotting wheel 21, the pressing wheel 31 and the feeding turntable 431 to rotate. The annular slotting knife 22 on the edge of the slotting wheel 21 breaks the soil layer during the rotation process, forming a neat planting trough. The feeding turntable 431 drives the seed scoop 433 to rotate, scooping seeds from the seed storage shell 41, and pouring the seeds into the collecting hopper 441 when it rotates above the collecting hopper 441. The seeds are accurately delivered to the opened planting trough through the discharge pipe 442.

[0031] Subsequently, the soil covering mechanism 6 begins operation. The soil covering angle iron 63, under the action of the resistance spring 64, adheres tightly to the ground, gently covering the soil on the seed-filled planting trough, ensuring full contact between the seed and the soil. The rubber pressure sleeve 32 behind the pressure wheel 31 presses the soil-covered planting trough, further compacting the soil and promoting seed rooting and germination. The scraper plate 7, attached to the side of the pressure wheel 31, promptly scrapes away any soil adhering to the surface of the rubber pressure sleeve 32, maintaining a stable pressure effect.

[0032] Throughout the sowing process, the operator must monitor the machine's operating status in real time. They must check the seeding status of the seed scoop 433 to ensure there are no missed or over-seeded seeds. They must also observe the slotting depth of the annular slotting blade 22 and the soil coverage of the covering angle iron 63, making minor adjustments if necessary. They must also regularly clean soil from the scraper blade 7 and rubber pressure sleeve 32 to prevent any degradation in seed quality. To change seed varieties or adjust row spacing, the operator can selectively place seeds into different seed storage housings 41 or increase or decrease the number of seed scoops 433.

[0033] After the operation is completed, turn off the drive motor 51 and clean the remaining soil and seeds on the various parts of the sowing machine. Take out the counterweight block in the placement slot 11 to reduce the weight of the equipment for easy transportation. Check the wear of the annular slotting knife 22, seed spoon 433 and other wearing parts, and replace or repair them if necessary.
